  • Patent number: 9977189
    Abstract: Apparatus and methods are described herein for cleaving an optical element at a defined distance from a splice (or other reference point/feature) of the optical element within a desired precision and/or accuracy. In some embodiments, a method includes receiving an indication of a location of a feature in an intermediate optical assembly visible within an image of the intermediate optical assembly. The feature can be for example, a splice. A position of the intermediate optical assembly is translated relative to a cleave unit based on the indication. After translating, the intermediate optical assembly, the intermediate optical assembly is cleaved to form an optical assembly that has an end face at a location disposed at a non-zero distance from the location of the feature. In some embodiments, the location of the feature can be determined with an image recognition system.

    Abstract: The present invention discloses a method for scribing and breaking a glass substrate and related device. The method includes: scribing the glass substrate to form a scribing notch; making a transmission medium of supersonic waves contact the scribing notch; transmitting supersonic waves to the scribing notch via the transmission medium to break the scribed glass substrate under an effect of supersonic waves. The present invention adjusts the frequency of the supersonic waves to make the frequency close to the natural frequency of the scribing notch such that they resonate together. Therefore, the resonation force is uniformly applied on all scribing notch. Therefore, this resonation force can break the scribed glass substrate along the scribing notch beautifully without any damages on the scribing notch and terminals.

  • Patent number: 8740029
    Abstract: Axial tension is applied to an optical fiber that had been scored at the intended cleave location, wherein the axial tension is applied in a time-varying manner to maintain the stress intensity factor for crack on the fiber within an acceptable level to produce a stable crack growth at a reasonable rate to cleave the fiber without requiring polishing of the end surface. Careful control of the applied tension force with time acts to control the velocity of the propagating crack by maintaining substantially constant stress intensity factor. The applied axial tension force is reduced with time and/or crack growth (as crack propagates). As a result, the strain energy in the fiber material is released by formation of a single plane with an optical quality surface without requiring polishing. A substantially flat optical surface of enhanced optical quality is formed at the cleaved end of the optical fiber.

  • Patent number: 8348115
    Abstract: A vertical crack is generated at a desired position on a brittle material substrate S by making a wheel tip 5a of a glass cutter 5 move while being in contact with the substrate surface by a load which does not allow the wheel tip 5a to damage the surface, using an armature 6 applying an abrupt impact force for generating the vertical crack having a predetermined depth, to the glass cutter 5 moving on the substrate. A scribe line is formed as the vertical crack is urged to extend along a planned scribe line, due to a stress gradient exerted onto the vertical crack and occurring between a compressive stress in an irradiation area on the substrate at which a laser beam is irradiated from a laser beam oscillator 8 and a tensile stress in a cooling area made by a cooling medium released from a cooling nozzle 7.

  • Publication number: 20120199625
    Abstract: Layers of material such as glass layers for displays may be cut using scribing and breaking techniques. Scribing-and-breaking equipment may include a scribe tip that forms a loop-shaped scribe line in the surface of a layer of material. The loop-shaped scribe line may have a rectangular shape with four straight sides and four rounded corners. A breaking structure such as a rectangular ring-shaped metal break frame with rounded corners may be configured to match the shape of the scribe line. During breaking operations, the layer of material may be supported on a support structure. The support structure may have a flexible material such as an elastomer and a lower-friction coating layer such as a polytetrafluoroethylene coating. The break frame may be aligned with the scribe line and may be used to press down on the layer of material, thereby breaking the layer of material along the scribe line.

    Abstract: In a wafer dicing press for reducing time and cost for wafer dicing and for evenly applying a dicing pressure to a whole wafer, a wafer dicing press includes a support unit supporting a first side of a wafer; and a pressurization device applying a pressure, by dispersing the pressure, to a second side of the wafer so that a laser-scribed layer of the wafer operates as a division starting point. Accordingly, the wafer dicing press reduces laser radiation and pressure-application times for dividing a wafer into semiconductor devices. This increased efficiency is achieved without increasing the likelihood of damaging the wafer.

  • Publication number: 20120048905
    Abstract: Apparatus and equipment for making glass sheet from a glass ribbon including scoring, bending and separation in vertical state with improved glass ribbon stability provided by edge restrainers located above the score-line that also travel with substantially the same vertical velocity with the elastic ribbon. The edge restrainers on both sides of the glass ribbon serve to limit the motion and perturbation of the ribbon during scoring, bending and separation, advantageously by tensioning the glass ribbon where needed. The invention can reduce disturbance of the glass ribbon in upstream visco-elastic and/or viscous zones due to scoring, bending and separation, therefore enhance forming process stability and product attributes such as thickness variation, stress and stress variation, and the like. The invention can be particularly advantageous for making glass sheet with large width and/or low thickness using the fusion down-draw, slot down-draw, re-draw down-draw, and other down-draw processes.
