This application claims the benefit of U.S. Provisional Patent Application Ser. No. 63/449,647, filed Mar. 3, 2023, and U.S. Provisional Patent Application Ser. No. 63/603,879, filed Nov. 29, 2023, which are incorporated by reference in their entirety herein.

BACKGROUND

A fiber optic cable or ribbon generally includes a protective or supporting material through which optical fibers extend. The cables or ribbons typically have connectors located on each end to connect them to other fiber optic cables or ribbons or to peripheral devices, and the connectors are high precision devices that position the optical fibers for optimal connection.

In order to pass light signals through optical fibers, the end face of the connector (from which a ferrule and optical fibers extend) must abut an adjacent connector in a specific manner. The high tolerances required of the parts to make these connections lead to precise shaping of the ends of the optical fibers via cleaving, cutting, and/or polishing. Apex offset, radius of curvature, fiber protrusion/recession, and angularity are all geometric parameters of the optical fiber end face that play into the quality of the signal passing through it. Final test measurements for back reflection and insertion loss are typically used as the final checks to determine the quality of the geometry (as well as the alignment, cleanliness, and surface finish of the finished cable). As such, the end face is usually cleaved, cut and/or polished to exacting standards so as to produce a finished product with minimal back reflection and loss. For example, it is often necessary to cleave, cut, and/or polish the end face of the connector to a precise length, i.e., so the end face projects a predetermined amount from a reference point such as a shoulder on the fiber optic connector within a predetermined tolerance. Fiber optic cables having multiple optical fibers can also be cleaved, cut, and/or polished to produce a particular performance specification.

Optical fiber polishers typically include a rotating platen and a polishing mechanism, such as a polishing arm mechanism (arm or overarm assembly), that positions and supports the connectors during the polishing process. Typically, the end face is lowered onto a film resting on the platen, and depending upon the film, the speed of the platen, the pressure applied, and its duration, acquires a product suitable for a particular application. Optical fiber polishers generally include a fixture coupled to the arm mechanism that is capable of holding and gripping one or more fiber optic connectors and advancing them under controlled conditions of speed and force to engage a plurality of fiber optic ends into engagement with a polishing member such as a rotatable platen having an abrasive surface (e.g., a platen with a pad having a film with an abrasive surface positioned thereon).

The manufacturing process for building a finished fiber optic connector typically involves polishing it at various speeds and pressures using various polishing films. Typically, the process will start with a more aggressive film of higher abrasive particle size at lower speeds and pressures and work toward smaller particle size films at faster speeds and higher pressures.

The various polishing films are currently manually positioned on the platen, which can cause delay in the process. In addition, the fixture is manually cleaned between polishing steps, and the next polishing film is wetted manually, which can also cause delay in the process.

For the reasons stated above and for other reasons stated below, which will become apparent to those skilled in the art upon reading and understanding the present specification, there is a need in the art for improved film or media exchange and cleaning.

DETAILED DESCRIPTION

In the following detailed description, reference is made to the accompanying drawings, which form a part hereof, and in which is shown by way of illustration embodiments in which the disclosure may be practiced. In this regard, directional terminology, such as “top,”“bottom,”“front,”“back,”“leading,”“trailing,” etc., is used with reference to the orientation of the Figure(s) being described. Because components of embodiments can be positioned in a number of different orientations, the directional terminology is used for purposes of illustration and is in no way limiting. It is to be understood that other embodiments may be utilized and structural or logical changes may be made without departing from the scope of the present invention. The following detailed description, therefore, is not to be taken in a limiting sense, and the scope of the present invention is defined by the appended claims.

It is to be understood that other embodiments may be utilized and mechanical changes may be made without departing from the spirit and scope of the present disclosure. The following detailed description is, therefore, not to be taken in a limiting sense.

Embodiments of the disclosure generally provide media exchange and cleaning assemblies for use with fiber optic polishing machines. Placing the appropriate polishing film, preferably including an underlying support plate or disc (e.g., glass plate or rubber pad), on the platen, after removing any polishing film from the platen, is referred to herein as media exchange. The terms polishing film and media are used interchangeably. It is recommended to clean the fixture and fiber optic connectors between polishing steps to prevent scratching from coarser media materials used in prior polishing steps. Although the assemblies are shown and described as being used together, with the same fiber optic polishing machine, it is recognized that either one or both can be used with a suitable fiber optic polishing machine. Also, the assemblies can be positioned on any side of the fiber optic polishing machine.

An example of a suitable optical fiber polishing machine is Model APM-HDC-5400 by Domaille Engineering, LLC of Rochester, Minnesota. An example of a suitable optical fiber polishing machine with controlled platen stopping positions is disclosed in PCT/US2022/052114, which is incorporated by reference herein. An example optical fiber polishing machine 100 is shown in the drawings. Although example polishing machines and components are shown and described, it is recognized that other suitable polishing machines and components can be used and the present invention is not limited to these examples. Because optical fiber polishing machines are generally known in the art, only relevant components of optical fiber polishing machine 100 are being generally described herein.

Alternatively, the grippers could be L-shaped members that engage the bottoms of the media plates. The L-shaped end effector component for lifting the media from underneath within the platen slots is operatively connected to a rectangular air cylinder and a coupler to the rod actuator. Optionally, the media can be pushed downward into position on the platen using the grippers or a suitable mechanical pusher.

Generally, the motor 150 moves the connector shaft 148, which moves the exchange arm 187 (the exchange arm 187 moves with the pivoting/rotating actuator connector 148). The pneumatic cylinders 161a, 161b, 161c, 161d move the connectors 162a, 162b, 162c, 162d, which move the lifting base 166 (the lifting base 166 moves up and down with the connectors 162a, 162b, 162c, 162d). The motor 194 moves the connector shaft (not shown), which moves the end effector 202 (the end effector 202 moves with the pivoting/rotating connector shaft) in a desired position relative to the platen by locating the pins with sensors 199. As shown in FIG. 5, cylinder actuators 215a and 215b (others not shown) incorporated into the film engaging assemblies 204a, 204b, 204c, 204d move the rods, which move the connectors and the grippers 217b, 217c, 217d in and out relative to the bases 205a, 205b, 205c, 205d. Air inlets 218a, 218b, 218c, and 218d receive air to push the cylinder actuators in and air inlets 219a, 219b, 219c, and 219d receive air to push the cylinder actuators out relative to the bases 205a, 205b, 205c, and 205d.

An example cleaning assembly 220, shown best in FIG. 9, includes a base 221 configured and arranged to engage the polishing machine 100. A receiving portion 222 is configured and arranged to receive a portion of the polishing machine 100, for example the spacer plate 110, and a clamp 223 secures the connection.

An arm 257 is operatively connected to the shaft 231 by positioning the second end 254 of the shaft 252 through a bore 259 in a first end 258 of the arm 257. A fastener 256 extends through the bore 259 of the arm 257 into the bore 255 of the shaft 252, and fastener 256 prevents the arm 257 from rotating about the shaft 252. A second end 260 of the arm 257 is operatively connected to a connector plate 262. The connector plate 262 includes apertures 263 proximate one side through which fasteners 267 extend to secure the connector plate 262 to the second end 260 of the arm 257. The second end 260 includes bores (not shown) configured and arranged to receive the fasteners 267. The connector plate 262 also includes apertures 264 proximate a middle and the other side and apertures 265 on opposing sides of the apertures 264. A connector plate 270 includes apertures 271 that align with apertures 264 and apertures 272 that align with apertures 265. The apertures 264 and 271 are configured and arranged to receive pins 275, and apertures 265 and 272 are configured and arranged to receive fasteners 277. The connector plate 262 includes a housing connecting portion 279, which is preferably generally circular with a central bore 281 and apertures 280 positioned about the bore 281. Fasteners 283 extend through the apertures 280 to connect a housing 308.

A manifold 285 includes a threaded extension 286 configured and arranged to extend through the bore 281. The manifold 285 includes a bore 287 extending through the threaded extension 286. A fitting 289 is operatively connected to a side of the manifold 285 and includes a bore 290 in fluid communication with the bore 287. An elbow 298 connects a mist nozzle 302 to the fitting 306.

A threaded tubing connector 294 with a bore 295 is operatively connected to the tube 292, and the tube 292 is operatively connected to the fitting 296. The fitting 296 includes a bore 297. The bores 287, 295 and 297 are aligned and in fluid communication and tubing 292 extends through them. Preferably, the tubing 292 is configured and arranged to receive water via fitting 296 and selectively deliver water to spray nozzle 302 and a nozzle/diffuser assembly (340, 354, 366), and a space within the bores around the tubing 292 is configured and arranged to receive air via fitting 289. This is shown best in FIG. 10.

The housing 308 is generally bowl-shaped to form a cavity 315 and includes a top 309 having apertures 311 configured and arranged to receive the fasteners 283. A fitting 318 connects through an aperture in the side 314 of the housing 308. The fitting 318 is for connecting a drain to the housing 308. The top 309 also includes an aperture (not shown) through which the tube 292 extends and connects through seal plate 354 within the housing's cavity 315. The spindle 322 is generally cylindrical with a threaded extension 323 having a bore 324. An O-ring 326 is positioned about the threaded extension 323, and a thrust bearing 328 including a bore 329 is positioned about the extension 323 and the O-ring 326. A cover 332 has a generally cylindrical side 333 and a bottom 335 forming a cavity (not shown). The bottom 335 includes an aperture 336 through which the extension 323 extends. Fixture splash guard 338 is operatively connected to the edge of the housing 308 to create a close fit to the polishing fixture to contain the water during the cleaning process. Multiple splash guards with a variety of aperture sizes will be available to fit different sized polishing fixtures.

A manifold 340 includes a generally central bore 341 configured and arranged to receive the extension 323. A first end 342 of the manifold 340 includes a first channel 343 extending from the bore 341 along a first side, and the first channel 343 includes an extension 344 branching out proximate its distal end. The first end 342 also includes apertures 345. In this example, there are preferably three apertures spaced along a second side of the first end 342. A second end 346 of the manifold 340 includes a second channel 347 extending from the bore 341 along the second side, and the second channel 347 includes an extension 348 branching out proximate its distal end. The second end 346 also includes apertures 349. In this example, there are preferably three apertures spaced along the first side.

A seal plate 354 includes a bore 355 aligned with bore 341. A first end 356 includes apertures 357 aligned with apertures 345 and apertures 358 aligned with the first channel 343. A second end 360 includes apertures 361 aligned with apertures 349 and apertures 362 aligned with the second channel 347. Fasteners 364 extend through the apertures 345, 357 and 349, 361 into apertures (not shown) in a diffuser 366 to connect these components.

As best shown in FIGS. 11 and 12, the diffuser 366 includes a first end 367 and a second end 374. The first end 367 includes a nozzle 368 with apertures 369 and 370 and a nozzle 371 with apertures 372 and apertures (not shown but similar to apertures 377). The second end 374 includes a nozzle 375 with apertures 376 and 377 and a nozzle 378 with apertures 379 and apertures (not shown but similar to apertures 370). Preferably, the apertures are staggered for better coverage. For example, the first end 367 includes three apertures 372 and three apertures similar to 377 and the second end 374 includes four apertures 376 and four apertures 377.

Generally, to move the cleaning assembly 220 from a storage position into a cleaning position, the stepper motor 230 rotates the shaft 231, the shaft 231 rotates the timing pulley 233, the timing pulley 233 rotates the timing belt (not shown), the timing belt rotates the timing pulley 239, the timing pulley 248 rotates the shaft 252, and the housing 308 and associated components move with the shaft 252. The rotary sensor 236 sends positional feedback to the computer.

A water source is connected to fitting 296, the aperture 297 of fitting 196 is connected to the water tube 292, which extends through apertures 295, 287, 281, 324, 341, and 355 allowing it to supply water to the diffuser 366, which preferably has an angled surface 366a, as shown in

FIG. 15. The water tube 292 is a close fit to the aperture 355 in the seal plate 354. This allows the manifold 340 to seal to the water tube 292 separating the air and water but allows the manifold to rotate and the water tube remain stationary. An incoming compressed air supply line is connected to fitting 289. The compressed air travel through aperture 290 into manifold 285 through aperture 287, 281, 324, and 341 outside of the water tube 292. Preferably, the air contacts angled surfaces on the nozzles proximate apertures 369, 372, 3376, 379 to fan out and water contacts the fanned air to help distribute the water in a fine mist during cleaning steps. This is shown in FIG. 15. If a drying step is desired, the water can be turned off and fanned air also helps during any drying steps. The diffuser can be spun or rotated using a motor or it can be air driven. The water and air pressure and duration can be controlled by the operator as needed.

The cleaning system can have user selected parameters including, but not limited to, water pressure, air pressure, rotation speed of the diffuser, direction of diffuser rotation, duration of cleaning, duration of drying, number of cleaning cycles, etc. There could also be a pre-rinse or pre-air cycle, which could be especially beneficial for the coarser media polishing steps.

Alternative designs could be used for the cleaning assembly spray bars. For example, as shown in FIGS. 16 and 17, a hollow shaft motor could be used for generating the rotation of the spray bar with diffuser and tubing carrying water or air or both into the cleaning bowl would transfer the fluids to the area. Instead of air with water diffuser type spray nozzles a water only conical type spray heads could be used to create conical liquid spray features rather than straight line type spray nozzles. In addition to conical type spray heads, it is recognized that any desired spray pattern and/or spray angle can be used (e.g., conical nozzles, linear nozzles, crossing linear nozzles, etc. could be used to produce pulsating spray, mist spray, flat spray, etc.). Brushes or other mechanical action can also be added. Also, as shown in FIG. 16, opposing sides can be used or, as shown in FIG. 17, just one side can be used relative to the axis of rotation of the spray manifold. Spray bars that are capable of 360 degrees rotation can be used or others that are limited to only rotating less than 360 degrees can be used. In FIG. 17, a quick connect fitting is used to bring water and air into the cleaning assembly via tubing. This arrangement would limit the spray bar rotation to less than 360 degrees. As shown in FIG. 18, a diverter diffuser could be positioned between the water outlets and the air outlets to create straight line water/air knife action while also preventing water from getting into the air outlets. Rather than using an angled iris contained bowl-shaped housing, an upright plate with a spray blocking member with a drip tray could be used. This is shown in FIGS. 19-21, which also shows different rotating bar concepts with spray nozzle and brush types for creating different types of water spray patterns and cleaning. An example brush bar 380 is shown in FIGS. 19 and 20. The drip tray can include a drain integrated into the rotating support post. The drain discards water and any slurry debris including material from media and/or fiber optic connectors.

In operation, for this example, using both the media exchange assembly 140 and the cleaning assembly 220 with a polishing machine 100, the operator positions the polishing films 108a, 108b, 108c, and 108d, which are preferably positioned on support members (e.g., glass plates, rubber pads, or any other suitable type of support members) for ease of exchange, on the polishing machine platen 107 and the media exchange platens 182b, 182c, and 182d. The operator leaves the first media exchange platen 182a empty. The first polishing step film 108a (e.g., roughing media) is positioned on the polishing machine platen 107, the second polishing step film 108b (e.g., first semi-finish media) is positioned on the second media exchange platen 182b, the third polishing step film 108c (e.g., second semi-finish media) is positioned on the third media exchange platen 182c, and the fourth polishing step film 108d (e.g., finish media) is positioned on the fourth media exchange platen 182d. The first media exchange platen 182a is left empty so that it is ready to receive the first polishing step film 108a after the first polishing step 108a. This is illustrated in FIG. 22. FIG. 6 shows a general polishing film 108 on the platen 107. With the overarm 116 in a storage or releasing position, the operator connects the polishing fixture 128 to the fixture connector 118 of the polishing machine 100. Preferably, the fixture 128 is pre-populated with fiber optic connectors, with their cables preferably restrained in a cable management mounted on the fixture 128, as known in the art. The optional fixture lift 126 is connected to the fixture 128, and the polishing process can begin. This is illustrated in FIG. 23. The first polishing step film 108a can be manually lubricated (e.g., misted with water). Although water is referenced as the lubricant, it is recognized that any suitable lubricant can be used.

The lock assembly 120 releases the overarm 116, and the optional positioning assembly 124 lowers the overarm 116 into an operating or polishing position. This is illustrated in FIGS. 24 and 25. The lock assembly 120 locks the overarm 116, and the polishing process begins the first polishing step. This is illustrated in FIG. 26. The fixture lift 126 can be used to lower the fixture 128 to engage the fiber optic connectors on the polishing film 108a. When the polishing step is completed, the fixture lift 126 raises the fixture 128, and preferably controlled platen stopping brings the platen 107 to the forward most position. If used, an example controlled platen stopping is described in PCT/US2022/052114, which is incorporated by reference herein. The lock assembly 120 unlocks the overarm 116, and the positioning assembly 124 raises the overarm 116 into a cleaning position, which can either be in an intermediate position as shown in FIG. 27 or an upright position (storage or releasing position). If used, the cleaning assembly 220 is rotated (by rotating the shaft 252) to position the housing 308 proximate the fixture 128 to start the cleaning process as shown in FIG. 28. During the cleaning process, the exchange arm 187 rotates to position the film engaging assemblies 204a, 204b, 204c, 204d proximate the platen 107 to begin exchanging the media (film) as shown in FIG. 29. The end effector 220 rotates to align with the platen pins 109, which also aligns the grippers 217b, 217c, 217d of the end effector 220 with the slots 107a in the platen 107. The exchange arm 187 lowers and then the grippers 217b, 217c, 217d are actuated to move inward within slots 107a to engage the media (polishing film 108a) as shown in FIGS. 30 and 31. The exchange arm 187 then raises, thereby raising the media (polishing film 108a) off the platen 107 as shown in FIG. 32, and rotates to proximate the first exchange platen 182a as shown in FIG. 33. The end effector 220 rotates to align with the exchange platen pins 183a so that the grippers are aligned with the slots 184a. The exchange arm 187 then lowers the media (polishing film 108a) onto the first exchange platen 182a, as shown in FIG. 34, and the grippers 217b, 217c, 217d are moved within the slots 184a outward to disengage the media (polishing film 108a) as shown in FIG. 35. The exchange arm 187 is raised so that the media (polishing film 108a) is positioned on the first exchange platen 182a as shown in FIG. 36. The exchange arm 187 rotates to the second exchange platen 182b and the end effector 220 rotates to align with the exchange platen pins 183b as shown in FIG. 37. The exchange arm 187 lowers onto the second exchange platen 182b, as shown in FIG. 38, and the grippers 217b, 217c, 217d on the end effector 220 are actuated to move inward within the slots 184b to engage the media (polishing film 108b) as shown in FIG. 39. The exchange arm 187 is raised, thereby raising the media (polishing film 108b) off the second exchange platen 182b as shown in FIG. 40. The exchange arm 187 rotates to the platen 107 and the end effector 220 rotates to align with the platen pins 109 as shown in FIG. 41. The exchange arm 187 lowers the media (polishing film 108b) onto the platen 107, as shown in FIG. 42, the grippers 217b, 217c, 217d are moved within the slots 107a outward to disengage the media (polishing film 108b), as shown in FIG. 43, and the exchange arm 187 is raised thereby leaving the media (polishing film 108b) on the platen 107 as shown in FIG. 44. The exchange arm 187 rotates to the first exchange platen 182a, as shown in FIG. 45, and the cleaning assembly 220 applies a mist of lubrication (e.g., water) via spray nozzle 302 onto the media (polishing film 108b) on the platen 107. The cleaning arm 257 rotates away when the cleaning is complete, as shown in FIG. 46.

The subsequent polishing and cleaning steps are similarly performed for a desired number of polishing steps. After the final polishing step, if used, the cleaning assembly 220 is rotated proximate the fixture 128 to start the cleaning process. The polishing process is complete. The operator removes the fixture 128 with the polished fiber optic connectors. The operator cleans or replaces the media (polishing films) and positions clean or replacement media, as previously described, for the next polishing process.

Advantages of embodiments of the present invention include an ability to implement full automation of polishing fiber optic connectors with very little human action. For example, an operator can position a loaded fixture and polishing films on the polishing machine and then can walk away and return to fully polished (e.g., four polishing steps) fiber optic connectors. This will increase efficiency and reduce human labor in the polishing process.

In one example, the various subcomponents or elements (e.g., elements 500) of the polisher 100 may be embodied in a plurality of different systems, where different modules may be grouped or distributed across the plurality of different systems. To achieve its desired functionality, polisher 100 may include various hardware components.

The polisher 100 may also include a USB port that connects to a keyboard to receive user input. It is not intended that this disclosure be limited by the above-described input devices. A person skilled in the art can readily appreciate that there are a number of input devices that can be implemented to allow a user to interface with the processor, including a keypad, a mouse, a switch, and buttons.

To perform a polishing process, operational parameters such as process time, platen speed, pressure, film type, pad type, lubricant type, platen stop position, and automation parameters may be entered for each step of the polishing process. The process of inputting this information into the polisher 100 may be performed by scrolling through a plurality of screens on the input device 114 and selecting from a menu of parameters. Once inputted, the procedure can be saved into memory and used by at least one processor of the polisher 100 immediately or at a later date.

In addition to communicating with polishing machine elements 502, the controller 504 may also communicate with automation control box elements 522 to monitor and control automation features of the polishing process in accordance with the operational parameters entered by a user. The controller 504 communicates with the automation control box elements 522 through IO PCB(s) with microprocessor 508, which is coupled to the automation data buffer PCB with microprocessor 524 via I2C communication link 520.

In some embodiments, a carrier ring for positioning a glass plate/rubber pad for a fiber optic polishing machine can be used. The carrier ring can have voids, grooved teeth, or other suitable registration features that mate with locking or registration features of the polishing platen on which the carrier ring is placed. The carrier ring and platen can provide easy rotation locking for the glass plate or rubber pad during the polishing process. In addition, the carrier ring can be easily picked up and set down for a manual user and/or an automated positioning system for the polishing machine. This is advantageous for fiber optic automation due to the rotating and revolving motion that is commonly seen with fiber optic polishing machines, resulting in reduced time for placing the carrier ring onto the platen for the polishing process.

The carrier ring and mating locking features may eliminate the need to locate anti-rotation features when placing the carrier ring. Further, as described herein, a carrier ring can add rigidity to semi-flexible rubber pads, making pick-and-place actions more robust, e.g., as it is generally more difficult to pick up a non-rigid object, such as a rubber pad. Furthermore, the carrier ring and locking features can reduce cross-contamination between media during media exchange events. For instance, when a robotic end effector touches a carrier ring and not polishing media, there may be less chance of polishing particles having one particular size migrating to polishing media having polishing particles of a different size during exchanges.

Referring now to FIGS. 57 through 61, a series of operational steps performed by an example polishing system 400 are depicted. An example carrier ring 410 is transferred from a supporting tray 416 to a platen 408. As described, the polishing system 400 includes a polishing machine 402 having a polishing arm 404 for supporting optical fibers for polishing operations. As described, the optical fibers can be brought into contact with an abrasive polishing substrate 406 by the polishing arm 404. For example, a set of optical fibers are bundled together and fixedly held by the polishing arm 404 for a polishing operation, where the optical fibers are pressed onto the abrasive as the platen 408 is rotated. The abrasive polishing substrate 406 can be mounted on a polishing plate 418 (FIGS. 68 and 69). The platen 408 of the polishing system 400 is configured to couple with the carrier ring 410 that supports the abrasive polishing substrate 406.

The carrier ring 410 and the platen 408 preferably each have multiple registration features 412 and 424 for rotationally fixing the carrier ring 410 with respect to the platen 408 when the carrier ring 410 is positioned to rest on the platen 408. The polishing system 400 includes an articulating arm 414 for moving the carrier ring 410 onto the platen 408 and off of the platen 408. As shown in FIG. 57, carrier rings 410 can rest on the supporting tray 416 adjacent to the polishing machine 402. For example, carrier rings 410 can be prepared using abrasives with differently sized polishing particles for different polishing operations and placed on the supporting tray 416 ready for use.

As described with reference to FIG. 58, the articulating arm 414 can grip a carrier ring 410 on the supporting tray 416. As described, the articulating arm 414 can be rotatably driven by a motor and corresponding gearbox (not shown) that is coupled to the polishing machine 402. In FIG. 59, the articulating arm 414 is shown transporting the carrier ring 410 to the platen 408. In FIG. 60, the articulating arm 414 is shown depositing the carrier ring 410 onto the platen 408. In this step, the multiple registration features 412 and 424 ensure proper alignment for rotationally fixing the carrier ring 410 with respect to the platen 408. With reference to FIG. 61, the articulating arm 414 is shown returned to an intermediate position between the platen 408 and the supporting tray 416.

Referring now to FIGS. 62, 63, 68, 69, 71, and 72, a carrier ring 410 is configured to support a polishing plate 418 within its periphery. For example, the carrier ring 410 can be a generally circular (e.g., annular) ring with an open center, where the polishing plate 418 is preferably supported in the center of the carrier ring 410. In some embodiments, the polishing plate 418 is formed of a rigid material (e.g., glass) and/or an elastomeric material (e.g., rubber or another elastomeric material). As described, the polishing plate 418 supports an abrasive polishing substrate 406. For example, the polishing plate 418 can be a glass plate or a rubber pad, and the abrasive polishing substrate 406 can be affixed to the glass or rubber surface. In an example where the polishing plate 418 is constructed from a glass material, water and/or adhesive can be used to affix the abrasive polishing substrate 406 to the glass.

In embodiments, the carrier ring 410 includes a top side 420, a bottom side 422, and registration features 424 on the bottom side 422 at the periphery of the carrier ring. For example, the registration features 424 can be circumferentially positioned around the bottom side 422 of an annular carrier ring 410 as shown in the accompanying figures. In some embodiments, the carrier ring 410 is at least substantially circularly shaped. In some embodiments, the carrier ring 410 includes at least one retaining feature 426 for securing the polishing plate to the carrier ring 410. For example, as shown in FIGS. 62 and 71, a carrier ring 410 includes a notch retaining feature 426 extending from an inner surface 428 of the carrier ring 410, which can also include a flange, ledge and/or other features for supporting the polishing plate 418.

Referring now to FIGS. 64 through 70 and 73, a platen 408 can be configured to couple with the carrier ring 410. The platen 408 can be driven to impart lateral polishing motion to the abrasive polishing substrate 406. However, lateral motion is described by way of example and is not meant to limit the present disclosure. In other embodiments, different polishing motions can also be used to drive the platen 408. As described, the platen 408 includes registration features 412 such that each one of the registration features 412 is configured to mate with at least one of the registration features 424 of the carrier ring 410. In embodiments, the carrier ring 410 is configured to be lowered onto the platen 408 to rest on the platen 408. The registration features 412 and the registration features 424 are configured to cause the carrier ring 410 to be rotationally fixed with respect to the platen 408 when the carrier ring 410 is lowered to rest on the platen 408 and the registration features 412 and 424 are aligned. For the purposes of the present disclosure, it shall be understood that terminology such as “rotationally fixed” is used to describe a substantially rotationally fixed alignment between the carrier ring 410 and the platen 408 but not necessarily a completely rigid alignment.

With reference to FIGS. 62 through 69, in some embodiments the registration features 424 on the carrier ring 410 are tapered recesses 430 (e.g., countersunk holes), and the registration features 412 on the platen 408 are locking pins 432. In one embodiment, the locking pins 432 each include a tapered head 440 (e.g., a bullnosed head) for interfacing with a respective tapered recess 430. In some embodiments, the locking pins 432 include a threaded surface 442 (or another retention surface, such as a knurled surface, a rigid surface, and so forth) for coupling the locking pins 432 to a respective receiving aperture 444 of the platen 408. In some embodiments, the locking pins 432 can be arranged circumferentially around the platen 408, e.g., across from one another. For example, multiple locking pins 432 (e.g., three locking pins 432, four locking pins 432) can be included with the platen 408. Referring to FIGS. 70 through 73, in some embodiments the registration features 424 on the carrier ring 410 can be a series of grooves 431 located about the periphery of the carrier ring 410 on the bottom side 422 of the carrier ring, and the registration features 412 on the platen 408 can be locking pins 433 that extend in a radial direction from a center of the platen 408 to engage the grooves 431. The registration features 412 and 424 can also be mating teeth or other suitable configurations.

It should be noted that the registration features 412 and 424 described herein are provided by way of example and are not meant to limit the present disclosure. Thus, in other embodiments, different registration features can be used, including registration features that do not involve tapered or curved surfaces. For example, one or more of the registration features 424 on the carrier ring 410 or the registration features 412 on the platen 408 can include magnets and/or electromagnets. For instance, in some embodiments, electromagnets (e.g., electrically powered by an electrical current source) on or proximate to a platen 408 can be used to selectively engage with permanent magnets and/or ferromagnetic material on a carrier ring 410.

An advantage offered by the registration features 412 and 424 of the carrier rings 410 and platens 408 as described herein is that such features allow for minor misalignments between a carrier ring 410 and a platen 408 as the articulating arm 414 (and/or another transport device) lowers the carrier ring 410 onto the platen 408. As the registration features 412 and 424 are brought into contact with one another, the carrier ring 410 and the platen 408 can be guided out of misalignment and into alignment by the registration features 412 and 424. Once the carrier ring 410 completely rests on the platen 408, the guidance offered by the interacting registration features 412 and 424 ensures final alignment between the carrier ring 410 and the platen 408.

For example, as described with reference to FIGS. 68 and 69, in some embodiments the carrier ring 410 and the platen 408 can be rotationally and/or translationally misaligned as much as one hundred and twenty thousandths of an inch (0.120″) with respect to one another and still be properly aligned upon placement of the carrier ring 410 onto the platen 408. As shown in FIG. 68, the initially misaligned carrier ring 410 is lowered onto the platen 408, and as the registration features 412 and 424 are brought into contact with one another, the registration features 412 and 424 correctly align the carrier ring 410 onto the platen 408, resulting in a proper final alignment as shown in FIG. 69.

In embodiments, the carrier ring 410 includes a flange 436 that protrudes proximate to the top side 420 of the carrier ring 410 such that the flange 436 can interface with arcuate protrusions 438 that extend from beneath the articulating arm 414 for lifting the carrier ring 410 from beneath the flange 436 (see, for example, FIG. 59). In this example, the articulating arm 414 includes opposing arms with protrusions 438, and as the opposing arms move inward and outward to engage and release the carrier ring 410, the protrusions 438 contact the carrier ring 410 below the flange 436, with the flange 436 extending into recesses formed in the opposing arms, as shown in FIG. 59. In some embodiments, the platen 408 may include one or more recesses 443 (e.g., blind holes as shown in FIG. 65) for coupling the platen 408 to a motor drive of the polishing machine 402. With reference to FIGS. 68 and 69, in some embodiments, the platen 408 includes a tapered ring 434 that guides the carrier ring 410 into alignment with the platen 408 as it is lowered to rest on the platen 408. In this example, the tapered ring 434 includes a tapered surface 446 proximate to an inner bore 448 of the tapered ring 434.

Another example optical fiber polishing machine 1000 with a media exchange assembly 1040 and a cleaning assembly 1120 is shown in FIGS. 74 and 99-101. This example shares similarities with previously described example(s) and, therefore, only significant differences will be described.

The media exchange assembly 1040 includes a base 1041 operatively connected to a media support base 1073 and the optical fiber polishing machine 1000 with connecting rods 1043. The media support base 1073 includes media support portions, preferably one for each polishing step. In this example, there are four media support portions 1074a, 1074b, 1074c, 1074d configured and arranged to support each carrier ring 410 supporting each polishing substrate 406. A gear box 1047 extends through an opening 1046 in the base 1041, and a connector 1048 extends upward from the gear box 1047 and a motor 1050 is operatively connected to a bottom of the gearbox 1047. The motor 1050 selectively rotates the connector 1048 in first and second directions, which are opposite directions. A housing 1049 is operatively connected to the base 1041 and contains the motor 1050 and a portion of the actuator 1047 therein. Pneumatic cylinders 1061 are operatively connected to and extend through the base 1041 to interconnect the base 1041 and a lifting base 1066. Preferably, the lifting base 1066 is a generally rectangular plate and a pneumatic cylinder is operatively connected proximate each corner of the plate. The pneumatic cylinders 1061 are configured and arranged to move the lifting base 1066 between an upward position 1068a (see for example FIGS. 79, 82, 99) and a downward position 1068b (see for example FIGS. 80, 81, 100, 101) relative to the base 1041. Sensor flags 1070 and 1072 can be operatively connected to opposing ends of the lifting base 1066 so that a sensor on an exchange arm 1087 can detect rotation of the exchange arm 1087 between positions.

The exchange arm 1087 is pivotally connected to the lifting base 1066, and the connector 1048 of the actuator 1047 extends through the lifting base 1066 and is operatively connected to a proximal end 1088 of the exchange arm 1087. Preferably, the connector 1048 extends into a bore 1086 in the exchange arm 1087. Thus, as the connector 1048 rotates the exchange arm 1087 pivots or rotates relative to the lifting base 1066. Optionally, a base 1085 is positioned between the lifting base 1066 and the exchange arm 1087 to support the exchange arm 1087 and the connector 1048 extends through a bore 1086 in the base 1085. In this example, the base 1085 is generally wedge-shaped. Bearings can be used between the lifting base 1066 and the base 1085 to help the exchange arm 1087 pivot or rotate relative to the lifting base 1066. Optionally, a cover 1084 can be operatively connected to the exchange arm 1087. A pneumatically driven actuator 1094 is preferably operatively connected to the cover 1084 and extends through an aperture 1091 in a distal end 1090 of the exchange arm 1087. Bases 1105a and 1105b are operatively connected to opposing sides of the actuator 1094 and are configured and arranged to move inward and outward relative to the actuator 1094 to move between a disengaged position 1107a (see for example FIGS. 79, 80, 99) and an engaged position 1107b (see for example FIGS. 81, 82, 100, 101). Preferably, each of the bases 1105a and 1105b includes grippers 1117a and 1117b, respectively, configured and arranged to receive and engage the flanges 436 of the carrier rings 410 when positioned in the engaged position 1107b.

An example of how the media exchange assembly 1040 operates is illustrated in FIGS. 79-82. FIG. 79 shows the lifting base 1066 in an upward position 1068a and the bases 1105a and 1105b in a disengaged position 1107b. When the bases 1105a and 1105b are positioned over the carrier ring 410, by rotating the exchange arm 1087, the lifting base 1066 is lowered into the downward position 1068b, as shown in FIG. 80. The bases 1105a and 1105b are aligned with the flange 436 of the carrier ring 410 in the disengaged position 1107a. The bases 1105a and 1105b are then moved inward into the engaged position 1107b, shown in FIG. 81, in which the flange 436 is positioned in the grippers 1117a and 1117b. The lifting base 1066 is then moved into the upward position 1068a thereby lifting the exchange arm 1087 and the carrier ring 410. The exchange arm 1087 can then be rotated to move the carrier ring 410 to the platen 408. Once the carrier ring 410 is positioned proximate the platen 408, the lifting base 1066 is lowered into the downward position 1068b and the bases 1105a and 1105b are then moved into the disengaged position 1107a to place the carrier ring 410 on the platen 408. Rotation of the platen 408 assists in seating the carrier ring 410 on the platen 408, as previously described. The exchange arm 1087 is then rotated out of the way to begin the polishing step and/or cleaning step, for example as shown in FIG. 99. Similar movements are made to remove the carrier ring 410 from the platen 408 and replace it with another carrier ring 410.

Referring to FIG. 83, the cleaning assembly 1120 includes a base 1121 with bores through which rods 1123 extend to operatively connect the base 1121 to the optical fiber polishing machine 1000. The base 1121 is preferably a rectangular plate with a circular receiving cavity 1124 in its top surface. An aperture 1125 is positioned in the center of the receiving cavity 1124, and a slot 1126 extends partially about the circumference of the receiving cavity 1124. A housing 1129 is operatively connected to the base 1121 below the receiving cavity 1124 and is configured and arranged to contain a motor 1130 and at least a portion of an actuator 1132 including an upwardly extending shaft 1133. The shaft 1133 extends through the aperture 1125 and into a connector 1136. Rotation of the shaft 1133 rotates the connector 1136, and bearings 1137 can be used to assist with the rotation. Optionally, a stop 1138 extends through the connector 1136 and into the slot 1126 to limit rotation of the connector 1136 relative to the base 1121.

Any suitable dispensing assembly can be used for dispensing water and/or air. An example nozzle/diffuser assembly includes a manifold 1240 shown in FIGS. 94, 95 and 96 and a diffuser 1266 shown in FIGS. 91, 92 and 93. The manifold 1240 includes a generally central bore 1241 configured and arranged to receive a fitting 1225. A first end 1244 of the manifold 1240 includes first channels 1242a and 1242b extending from the bore 1241, and a second end 1245 of the manifold 1240 includes second channels 1243a and 1243b extending from the bore 1241. On the top side of the diffuser 1266 includes nozzles 1268, 1271, and 1275 with apertures 1269, 1272, and 1276, respectively. Between the nozzles 1268, 1271, and 1275 are surfaces 1270 that could include brushes or any suitable material configured and arranged to assist with cleaning. Alternatively, as shown in FIG. 91A, brush bars 1280 could extend outward from the diffuser 1266 and include brushes 1281 proximate their distal ends. On the bottom side of the diffuser 1266 a first end 1262 includes a first channel 1263 extending from the bore 1261, and a second end 1264 of the diffuser 1266 includes a second channel 1265 extending from the bore 1261. A connecting plate 1254, shown in FIGS. 83, 97, and 98, can be used between the manifold 1240 and the diffuser 1266. The connecting plate 1254 separates the first channel 1263 and the second channel 1265 of the diffuser 1266 used for water and the first channels 1242a and 1242b and the second channels 1243a and 1243b of the manifold 1240 used for air. The small apertures 1255 in the connecting plate 1254 allow air to pass from the first channels 1242a and 1242b and the second channels 1243a and 1243b of the manifold 1240 to the apertures 1267 (small holes outside of the channels) of the diffuser 1266.

Shafts 1152 interconnect the connector 1136 and an arm 1157, and shafts 1162 interconnect the arm 1157 and a housing 1208, which is preferably generally bowl-shaped in this example. A motor 1222 is operatively connected to a rear of the housing 1208. A cover 1220 contains the motor 1222, and a shaft 1223 extends outward from the motor 1222 and through an aperture in the rear of the housing 1208. A fitting assembly 1217 is operatively connected to the cover 1220 and extends through the motor 1222, the shaft 1223, the fitting 1225, the manifold 1240 and the connecting plate 1254 into the bore 1261. The fitting assembly 1217 provides a connection to a water source. A fitting assembly 1219 (FIG. 87) is operatively connected to the cover 1220 and extends about a portion of the fitting assembly 1217 into the manifold 1240 and provides a connection to an air source. A fitting assembly 1218 (FIG. 83) provides a connection to a waste hose. The fitting assemblies 1217 and 1218 connected to the manifold 1240, which is connected to a connecting plate 1254 and a diffuser 1266 are for dispensing water and/or air within a cavity of the housing 1208. The motor 1222 assists in rotating the dispensing assembly including a nozzle/diffuser assembly. A misting nozzle assembly 1221 (FIG. 88) is also operatively connected to the cover 1220.

After a polishing step, the fixture and the cleaning assembly are moved into cleaning positions, for example as shown in FIGS. 99-101. In this example, the motor 1130 causes the shaft 1133 to rotate, which causes the connector 1136 to rotate thereby moving the housing 1208 from a storage position (see for example FIG. 74) to a cleaning position (see for example FIGS. 99-101). In the cleaning position, the fixture is received within the cavity of the housing 1208. Water and/or air is/are dispensed using a suitable dispensing assembly. For example, water could be dispensed to clean the fixture and air could be used to supplement the cleaning action. Air could be used to at least partially dry the fixture. If the diffuser 1266 includes a brush or any suitable cleaning material, the brush or suitable cleaning material assists in cleaning via contact with the fiber optic ends and/or at least a portion of the fixture. The nozzle/diffuser assembly could include a brush or be substituted with a brush.

An optional feature of embodiments is an iris assembly 1290, which can selectively and adjustably close about the fixture after the cleaning assembly is placed in its cleaning position. If used, the iris assembly will help prevent water from escaping the cleaning bowl during the cleaning process. The iris assembly 1290 is preferably operated by an air cylinder 1224 that partially extends out of the top of the cleaning bowl or housing 1208. A connector 1229 connects the air cylinder 1224 to the housing 1208. The iris assembly 1290 includes a plurality of pivotally connected blades 1291 that are operatively connected to an adjuster ring 1236. The adjuster ring 1236 includes an extension tab 1238 that is pivotally connected via a connector 1230 to the rod 1228 of the air cylinder 1224. One end of each blade 1291 is pivotally connected to another blade 1291 with a hinge 1293, and the other end of each blade 1291 includes a connector 1292 that extends into a slot 1237 in the adjuster ring 1236. The slots 1237 are angled so that as the adjuster ring 1236 is turned or rotated by the air cylinder 1224, via the rod 1228 moving the extension tab 1238 of the adjuster ring 1236, the connectors 1292 can move within the slots 1237, which cause the blades 1291 to pivot relative to one another. When the adjuster ring 1236 is turned in one direction, the blades 1291 pivot and move toward a closed position. When the adjuster ring 1236 is turned in an opposite direction, the blades 1291 pivot and move toward an open position. Preferably, a selector button 1234 is positioned in a desired position within a plurality of selector apertures 1233 to adjust how far the blades 1291 of the iris assembly 1290 close thereby providing several closed positions. When the connector 1230 contacts the selector button 1234, which acts as a stop, the rod 1228 is prevented from moving thereby limiting movement of the blades 1291 relative to one another. As illustrated in FIGS. 86 and 89, the selector button 1234 is positioned to allow the blades 1291 to move into a first selected closed position relative to a fixture. As illustrated in FIG. 90, the selector button 1234 is positioned to allow the blades 1291 to move into another selected closed position relative to a fixture. The desired position of the blades 1291 could depend upon the number and the type of fibers being polished. A cover 1232 can be used to protect the iris assembly 1290.

FIG. 102 is a block diagram illustrating one example of a processing system 800 for a polishing machine (e.g., 100 of FIG. 1) including a media exchange assembly (e.g., 140 of FIG. 1) and a cleaning assembly (e.g., 220 of FIG. 1). Processing system 800 may be part of polishing machine elements 502 and/or automation control box elements 522 previously described and illustrated with reference to FIG. 47. Processing system 800 includes a processor 802 and a machine-readable storage medium 806. Processor 802 is communicatively coupled to machine-readable storage medium 806 through a communication path 804. Although the following description refers to a single processor and a single machine-readable storage medium, the description may also apply to a system with multiple processors and multiple machine-readable storage mediums. In such examples, the instructions may be distributed (e.g., stored) across multiple machine-readable storage mediums and the instructions may be distributed (e.g., executed by) across multiple processors (e.g., 504, 506, 508, 510, 524, 526, 528, 530, and/or 532 of FIG. 47).

Processor 802 includes one (i.e., a single) central processing unit (CPU) or microprocessor or more than one (i.e., multiple) CPU or microprocessor, and/or other suitable hardware devices for retrieval and execution of instructions stored in machine-readable storage medium 806. Processor 802 may fetch, decode, and execute instructions 810-818 to operate optical fiber polishing machine 100 (FIG. 1) including media exchange assembly 140 (FIG. 1) and cleaning assembly 220 (FIG. 1).

Processor 802 may fetch, decode, and execute instructions 810 to move a first polishing media (e.g., 108a-108d of FIG. 2) from a first media exchange platen (e.g., 182a-182d of FIG. 1) to a polishing machine platen (e.g., 107 of FIG. 1). Processor 802 may fetch, decode, and execute instructions 812 to lower a fixture (e.g., 128 of FIG. 2) from a first fixture position (e.g., illustrated in FIG. 24) to a second fixture position (e.g., illustrated in FIG. 25) proximate the polishing machine platen to polish at least one optical fiber supported by the fixture via the first polishing media. With the polishing complete, processor 802 may fetch, decode, and execute instructions 814 to raise the fixture to the first fixture position. Processor 802 may fetch, decode, and execute instructions 816 to rotate a cleaning assembly (e.g., 220) from a first cleaning assembly position (e.g., illustrated in FIG. 27) to a second cleaning assembly position (e.g., illustrated in FIG. 28) proximate the fixture to clean the at least one optical fiber.

In some examples, processor 802 may fetch, decode, and execute additional instructions 818. In some examples, processor 802 may fetch, decode, and execute additional instructions 818 to, during the cleaning of the at least one optical fiber, move the first polishing media from the polishing machine platen to the first media exchange platen; and move a second polishing media from a second media exchange platen to the polishing machine platen. In some examples, processor 802 may fetch, decode, and execute additional instructions 818 to apply, via the cleaning assembly, a mist of lubricant (e.g., illustrated in FIG. 45) onto the second polishing media; and rotate the cleaning assembly to the first cleaning assembly position. In some examples, processor 802 may fetch, decode, and execute additional instructions 818 to receive, via a user interface (e.g., 114 of FIG. 1, 504 of FIG. 47), a mist spray pressure parameter and a mist spray duration parameter (e.g., entered in region 636b of display screen 630 of FIG. 52B); and wherein the instructions to apply the mist of lubricant comprises instructions to apply the mist of lubricant onto the second polishing media based on the mist spray pressure parameter and the mist spray duration parameter.
