The present disclosure claims priority to the U.S. Provisional Application No. 62/694,479 filed Jul. 6, 2018, which is hereby incorporated by reference.
FIELDThe present disclosure relates generally to a system and method for flexible manufacturing. More particularly, the present disclosure relates to a system and method for flexible manufacturing that includes a press, a quick-exchange tooling apparatus, and modular moveable elements allowing fully automatic or semi-automatic manufacturing.
BACKGROUNDFlexible manufacturing has become more and more important in industry due to the rapid pace of change and the desire of consumers to personalize products. Manufacturing equipment needs to be more adaptable so that it is easier to make changes without large downtime in between production runs.
Conventional flexible manufacturing systems typically involve components/elements such as overhead cranes or robots that allow for x-y movement above a work area so that various tools can be kept on a nearby tool rack or the like and then provided to the crane/robot when moved away from a work area. One of the elements that has been difficult to include in these flexible manufacturing systems is a press. Some systems involve a press hanging from an overhead support beam. However, press forces that can then be applied to a part or parts are limited by the maximum loading on the overhead beams. Other systems involve the use of a press and a table where a part is moved along the table under the press. These systems are limited because the table is positioned between the press plates. Thus, the table can prevent inhibit changeover of tooling on the press plates. Further, it can be difficult to complete other types of operations on a part (for example, diagnostic testing, manual assembly, and/or the like) while it is at the press and the part may need to be moved to another station for these operations.
As such, there is a need for an improved system and method for flexible manufacturing that overcomes at least some of the noted issues.

Other aspects and features of the present disclosure will become apparent to those ordinarily skilled in the art upon review of the following description of specific embodiments in conjunction with the accompanying figures.
Embodiments of the present disclosure will now be described, by way of example only, with reference to the attached Figures:
Generally, the present disclosure provides a manufacturing system for flexible manufacturing. The manufacturing system includes a cell framework defining a manufacturing area, at least one workplace within the manufacturing area, and at least one manufacturing component configured to be movable within the manufacturing area in relation to the at least one workplace. The manufacturing system also has a conveying mechanism configured to move a part or workpiece into the at least one workplace to be worked on by the at least one manufacturing component.
In some embodiments, the manufacturing component includes a multiple-axis sliding structure, a C-frame provide to the multiple-axis sliding structure and movably coupled to the multiple-axis sliding structure, and one or more tools demountably coupled to the C-frame.
The multiple-axis sliding structure may be movable in a three-dimensional (3D) space of the manufacturing area, for example along mutually orthogonal x, y, and z axes, and, in particular, about the workplace for precisely positioning one or more tools at desired 3D positions with respect to the workplace and/or the components therein such as a pallet, a fixture, or a workpiece to be operated on.
In some embodiments, the tools may include a press coupled to the C-frame and configured for applying an enhanced press force to the workpiece. In some embodiments, the press may be a rotatable press. In some embodiments, the press may be a machine press. In some embodiments, the press is intended to have an actuation path. In some cases, a tool exchanger having a plurality of tools can be coupled to the C-frame and may include a lower end of the rotatable press. The tool exchanger may be rotated to select a tool. The press may engage and drive the selected tool without transmitting the press force to the tool exchanger.
In some embodiments, the manufacturing system may include two or more workplaces accessible to the manufacturing component. In some embodiments, the manufacturing system may include two or more manufacturing components accessible to a common workplace. Depending on the configuration and manufacturing needs, the two or more manufacturing components may operate on or with a same workpiece or separate workpieces, and the two or more manufacturing components may operate in parallel or in serial.
In some embodiments, the above-described manufacturing system is modularized and forms a manufacturing module that may be used with other modules to form an expanded manufacturing system. For example, such a modular manufacturing module may be coupled with one or more robot modular modules in a “front-to-front” manner and/or a “side-by-side” manner to allow the robots in the robot modules to access the workplace of the manufacturing module and the workpieces therein.
Turning now to
The cell framework 102 in these embodiments is formed by a base structure 112 and a frame 114 thereabove. The frame 114 includes a front entrance 116 having one or more doors 118, and a console or control terminal 120, which may be mounted at or near the front entrance 116. As will described in more detail below, the manufacturing system 100 may be configured in an automatic manufacturing mode in which the doors 118 may be closed for safety, or may be configured in a semi-automatic manufacturing mode in which the doors 118 may be open for an operator to access the workplace 106 and other components in the manufacturing area 104 as needed.
In these embodiments, the workplace 106 includes a supporting structure fixed in the manufacturing area 104 near the front entrance 116 for supporting a pallet 124. The manufacturing system 100 may include a pair of tracks 122A and 122B with a suitable conveying mechanism (not shown) such as one or more rollers and/or conveyor belts for moving a pallet 124 into the workplace 106. The tracks 122 may be mounted to the frame 114 or may be at a small distance from the frame 114 as shown in
The manufacturing component 108 may include a sliding structure 132, a C-frame 134 vertically movably coupled to the sliding structure 132, and one or more tools coupled to the C-frame 134. The sliding structure 132 is intended to allow for the positioning of the C-frame 134 coupled with one or more tools. The one or more tools may include one or more permanently-mounted tools such as a press 136 and/or one or more quick-exchange tools 138 that may be demountably installed onto the C-frame 134 as needed via a tool exchanger 140. In some cases, mounted tools may be decoupled from the C-frame 134 to allow coupling of another mounted tool to C-frame 134. In some cases, the tools may be installed beside the press 136. In other cases, the tools may be installed onto the press 136.
As shown in
The longitudinal slider 144 includes a sliding structure (not shown) for laterally slidably engaging the rails 148 of the lateral slider 142. Similar to the lateral slider 142, the longitudinal slider 144 also includes a pair of parallel rails 156 longitudinally extending along the y-axis for longitudinally slidably supporting a column 146 thereon. A driving device (not shown), such as a servo coupled to the column 146 and a pulley-belt system 158 or the like, is used for moving the column 146 and components on the longitudinal slider 144 along the y-axis during a manufacturing cycle.
The column 146 includes a sliding structure (not shown) for longitudinally slidably engaging the rails 156 of the longitudinal slider 142, a pair of pneumatic cylinders 162, and a C-frame 134 vertically movably mounted on a C-frame-mounting surface 166 thereof facing the workplace 106 and the front entrance 116. The C-frame 134 includes an electro-mechanical press 136 mounted onto an upper arm 172 thereof and a press plate 174 mounted onto a lower arm 176 thereof. Electro-mechanical press 136 may be, for example, a machine press. The pneumatic cylinders 162 is configured for vertically sliding the C-frame 134 along the z-axis to engage the press plate 174 with a pallet 124 positioned onto the workplace 106 (not shown in
When assembling the sliding structure 132, one may first slide the longitudinal slider 144 onto the lateral slider 142, and then slide the column 146 onto the longitudinal slider 144.
By controlling the servos and the pneumatic cylinders 162 of the lateral slider 142, the longitudinal slider 144, and the column 146, the manufacturing component 108 is therefore movable within the 3D manufacturing area 104 along the x, y, and z axes. Subsequently, while the workpiece 184 is on pallet 124 (and in the workplace 106) and is stationary, the tools of the manufacturing component 108 are movable within the 3D manufacturing area 104 in relation to the workplace 106 about the workpiece 184 thereon for accurate positioning and/or for multiple operations during a manufacturing cycle. For example, manufacturing component 108 may be moved to an operating position within workplace 106 to complete an automated operation on the workpiece 184. Compared to conventional systems that use a conveyor to move the pallet and workpiece 184 thereon towards the tool, the manufacturing system 100 disclosed herein is intended to reduce the tolerance stack between the tools and the workpiece 184, thereby giving rise to improved positioning precision.
An advantage is that the manufacturing component 108, e.g. press 136, may be moved completely away from a part so that new fixtures/tooling can be introduced on, for example, the press plates. For example, manufacturing component 108 may be moved to a standby position away from the part as needed, for example, to complete separate operations on a part such as diagnostic testing, manual assembly, and/or the like,
As the manufacturing component 108 (press 136) is supported by the ground or the base structure 112 of the cell framework 102 via the C-frame 134 and the multiple-axis sliding structure 132, the manufacturing component 108 may be capable of providing an enhanced press force. C-frame 134 may support press 136 by transmitting equal and opposite force back into the workpiece 184 via press plate 174 and therefore manufacturing component 108 may be capable of providing an enhanced press force. For example, in some embodiments, the manufacturing component 108 may provide a maximum press force greater than 12 kN (12,000 Newtons). In some embodiments, the manufacturing system 100 may provide a maximum press force of about 65 kN.
In comparison, conventional manufacturing systems may only be able to provide a maximum press force of lower than 12 kN through rails and may have about 50 μm deflection. Moreover, conventional manufacturing systems may require the workpiece 184 to exit the manufacturing system for any pressing work.
The manufacturing component 108 supports a variety of tools such as the press 136 and quick-exchange tools 138 such as gaging tools, rundown tools, pick-and-placing tools, and the like, and may have a plurality of tools installed thereon for use. In these embodiments, the press 136 may be a rotatable press such as a Rotational Electro-Mechanical Assembly Press (REMAP) offered by Promess Incorporated of Brighton, Mich., U.S.A., which may be used for pressing and for driving quick-exchange tools 138.

As shown in
The turret 182 is coupled to a gear 200 and the combination thereof is rotatably coupled to the front surface 192 of the tool-exchanger housing 190. The gear 200 engages the tool-indexing servo 196 via a gear system (not shown) for rotating the turret 182 to select a tool thereon. Of course, those skilled in the art will appreciate that in some alternative embodiments, the turret 182 may be rotated by the servo 196 via an endless belt or other drive system and tool exchanger 140 does not include the gear 200.
The turret 182 is in a frustum shape with a sidewall 202 tapering from a proximal end coupled to the gear 200 to a distal end thereof. The sidewall 202 of the turret 182 includes a plurality of tool-mounting structures 204 (for example six tool-mounting structures 204 in
Those skilled in the art will appreciate that in some embodiments, at least one of the rotary tool-couplings 206A may be driven by an electrical drive for rotation.
The tool exchanger 140 may be configured in an operation mode wherein the tools 138 attached thereon may be in operation for manufacturing or an indexing mode wherein the tool exchanger 140 may be automatically or manually rotated to select a tool 138. As shown in
As shown in
As shown in
As described above, the press arm 136 extends into the tool-exchanger housing 190. The press arm 136 includes a press-and-rotate coupling 224 at the lower end thereof which seats on the circumferential shoulder 222 of the rotary tool-coupling 206A and is releasably fastened to the rotary tool-coupling 206A by a connect/disconnect mechanism 226 controllable by, for example, a release handle 228 such that the rotary tool-coupling 206A and the tool attached thereon (not shown) may be rotated and upwardly/downwardly moved by the press 136. Moreover, when the press arm 136 engages the rotary tool-coupling 206A and the tool attached thereon, the press forces of the press arm 136 are transmitted to the attached tool without being applied to the tool exchanger 140.
As shown in
The turret 182 may be indexable, where an indexable turret includes a turret that may be rotated between a plurality of fixed rotary positions, wherein each fixed rotary position aligns a respective one of the one or more tool-couplings with the press arm 136. An indexable turret may be advantageous since a desired tool may be aligned with the press arm 136 quickly and reliably by selecting the corresponding fixed position, rather than continuously monitoring the position of the tool as the turret 182 rotates and then halting rotation of the turret 182 when alignment is achieved.
