  • Publication number: 20110266325
    Abstract: In a breaking operation, a substrate is moved so that a blade can be situated in line with a scribe line, and the blade is lowered to break the substrate. After the breaking, the blade is raised. Then, the substrate is moved along its surface while taking an image of the substrate by using a camera after the breaking. Moreover, the blade is lowered to break the substrate. After the breaking, the blade is raised. Then, the substrate is moved along its surface while performing image processing concurrently. After the movement of the substrate, the position of the substrate is corrected so that the following scribe line to be cut for breaking can be situated immediately below the blade. In this way, the time required for breaking the substrate formed with a multiplicity of scribe lines into pieces can be shortened.

  • Publication number: 20100127034
    Abstract: An apparatus and method for cleaving an optical fiber. The method includes supporting a connector in a fixed axial position along an axis of an optical fiber extending from an end of the connector, and placing an axial tension along the axis of the optical fiber. A fiber engaging member is moved along an arcuate path such that a sharpened blade tip of the fiber engaging member cuts across a cut location of the optical fiber. The axial tension induces crack propagation through the thickness of the optical fiber at the cut location.

  • Patent number: 7717311
    Abstract: Vertical cracks Vm in the thickness direction of a mother glass substrate 10 are sequentially formed along lines to be scribed and broken, and thus main scribe lines MS are formed along the lines to be scribed and broken of the mother glass substrate 10. Then, subordinate scribe lines SS are formed along the main scribe lines MS which have been formed, at a predetermined distance from the main scribe lines MS. Thus, the mother glass substrate 10 is broken along the main scribe lines MS. In this manner, the substrate can be scribed and broken efficiently without requiring a complicated device or the like.

  • Patent number: 7710533
    Abstract: A liquid crystal display (LCD) panel is fixed to a supporting stage by vacuum holding in a way that an end portion of a predetermined one of edges of the pair of substrates protrudes from the supporting stage. Next, scribe lines are formed respectively in positions on upper and lower surfaces of the end portion of the pair of substrates, and the end portion protruding from the supporting stage. Thereafter, a load is applied to a predetermined position by using a break pin. The load is applied to the predetermined position at a side of the scribe lines toward the outside closer to starting points of the respective scribe lines. Accordingly, the LCD panel is cut.

  • Patent number: 7699199
    Abstract: A method for producing glass plates of any desired contour from sheet glass, comprising the following steps: scribing scribe lines into a least one face of the sheet glass along the contour down to a depth, using a cutting device, and positioning the glass plate on a support. The method is further characterized in that a defined force F is applied to the sheet glass so that it breaks along the scribe lines, said break extending through the entire thickness of the sheet glass. The flat glass may be sandwiched between two flexible plates prior to being placed on a base pad and being subjected to the breaking force.

  • Publication number: 20100044406
    Abstract: There are provided an optical fiber cutting method and a cutting apparatus which can easily cut a coated optical fiber without a step of removing a coating from the optical fiber. It includes a clamp which holds the coated optical fiber, having a glass fiber and the coating, on both sides of a portion-to-be-cut, a disk-shaped blade member which moves at the portion-to-be-cut in a direction orthogonal to an axis of the optical fiber to cut the coating and to provide a slit into the glass fiber, and a support which presses, with a predetermined pressing force, the portion-to-be-cut from an opposite side of the blade member with respect to the portion-to-be-cut when cutting the coating and providing the slit into the glass fiber. A head of the support is formed with a groove along a sliding direction of the blade member.

  • Patent number: 7665394
    Abstract: The dispenser dispenses tickets such as instant-winner lottery tickets from a strip in which the individual tickets are delineated by perforation lines. The dispenser includes a separator to tear the tickets apart before issuing them from the machine. The separator preferably is rotary and has a dull helical blade which rotates to contact the ticket strip adjacent a perforation line, and presses against the strip to tear the tickets apart along the perforation line at a point which progresses across the strip along the perforation line. Preferably, a bar code reader is provided for reading codes on tickets in the dispensing machine. The bar code reader is used in reading information from the tickets to initialize the dispenser control system and in accounting for the sale of tickets, and in the verification of winning tickets being sold. A game is provided in which the concept is that a jackpot is built up using the detection of each ticket sold.

  • Patent number: 7638730
    Abstract: Disclosed herein is an apparatus for cutting a glass plate. The apparatus comprises a cracking means for forming a minute crack at a point on the glass plate where the cutting is started, at least one scribing means using a laser beam absorbed by the glass plate, at least one quenching means using a quenching fluid after irradiation of the laser beam, a breaking means using the laser beam. The breaking means comprises a laser oscillator, a reflection mirror and a focusing lens. The focusing lens has at least two or more focal lengths. The apparatus may further apparatus further comprise a photo mask formed with light transmission openings for transmitting a part of the laser beam to be irradiated on the glass plate instead of the focusing lens. With the apparatus of the present invention, the problems caused by the conventional lens, such as a reduced straightness of a cutting line or a rough cutting plane, can be prevented, thereby providing a clean cutting plane.

  • Publication number: 20090250497
    Abstract: A pane is separated from a moving ribbon of brittle material by restraining the ribbon upstream of a score line prior to separating the pane. The ribbon is restrained by selectively contacting a first side and a second side of the ribbon in one of an opposite, overlapping or offset relation. The ribbon can be restrained prior to, substantially simultaneous with or subsequent to forming the score line. The restrained status of the ribbon is maintained during and immediately after separation of the pane from the ribbon, thereby reducing the introduction of a disturbance or bending moment into the upstream ribbon.
