  • Patent number: 6412677
    Abstract: There is disclosed a method of cutting a plate glass mother material in which a plurality of grooves are scribed/processed beforehand on one main surface, and appropriate pressing is constantly performed, so that more preferable materials to be pressed can be formed. When a plate glass mother material 20 is pressurized by an indenter 191, and cut in a portion of groove D1, vibration is momentarily generated. The vibration is transmitted to a vibration sensor 193 via an indenter base 190. Subsequently, at the time when the vibration sensor 193 detects the vibration, a Z-axis servo motor 192 of a pressing device 19 stops, and pressing by the indenter 191 stops. Therefore, the indenter 191 does not advance by more strokes than necessary, glass in a cut portion can be prevented from being chipped.

  • Publication number: 20020079342
    Abstract: A tool for separating a common printed wiring board substrate into a plurality of substrates where, prior to separation, the plurality of substrates are connected by at least one circuit connector. The purpose of the tool is to apply pressure along a dividing line to break the common substrate into separate boards without crimping or breaking the connectors between the boards. In a preferred embodiment, the tool has a beveled edge for contacting the common substrate with mechanism for adjusting the location of notches in the beveled edge. The notches are for alignment with the location of the connectors between the boards.

As the rotors are rotated further, the ampule in the grooves is pushed down and cut off along a cutoff line formed between this and the immediately upper ampules by the rear edges of the grooves, with the upper ampules supported on cylindrical outer surfaces of the rotors.

  • Patent number: 5944244
    Abstract: Apparatus for dividing laminated glass consists of a device for dividing laminated glass, and a glass cutting table 30 with a cutting bridge 33 which can move along a support and on which a cutting head 38 for scratching plates of glass can move. The device for dividing laminated glass is located on one of the edges of glass cutting table 30 which run parallel to cutting bridge 33. On cutting bridge 33 of glass cutting table 30 there is stop 40 for orienting the laminated glass in the device for dividing laminated glass. Thus the amount of space required is reduced. The device for dividing laminated glass can also be made narrower or can have only one movable support 5 if a support 2 affixed to the frame is made integral with the bearing surface of glass cutting table 30. The glass cutting table is not used to divide the laminated glass: only its cutting bridge is used, and only as an adjustable support for the stop 40.

  • Patent number: 5913468
    Abstract: An improved method and device for separating parts from the sheet metal carrier. In particular, a single sheet from a stack of sheets having parts micro-joined to the carrier sheet is transported to the nip of a pair of pinch rollers. The pinch rollers move down to engage the front edge of the sheet, the pinch rollers moving the sheet to the nip formed between a pair of main rollers. The main rollers then move together to the drive position and transport the sheet to a separation device on the opposite side of the main rollers. The main rollers drive the sheet material in a manner such that the top surface of the leading edge of the sheet metal is engaged below the forward tip of the separation device. The separation device is then moves downwardly so that the upper surface of the separation device assembly is level to the part pass line.

  • Patent number: 5911349
    Abstract: For a device for fracture separating bearing covers of aligned bearing bores in bearing arrangements of a machine member, which comprises a guided separating element which is profiled in an approximately semicircular shape and acts in the center onto a bearing cover in the bearing bore, for obtaining a device which is structurally simple, it is suggested that, for the fracture separating, a half-mandrel or full mandrel, which can be axially arranged in one or several bearing bores, is provided. An operating linkage, which only causes the guiding of the respective mandrel in the fracture separating direction, is applied to the respective mandrel transversely to its longitudinal course, the respective mandrel being held in a rotationally secured manner and each bearing cover being rotationally secured while being clamped against the respective mandrel.

  • Patent number: 5853101
    Abstract: The present invention is directed to a blister pack opener which includes a structure designed to receive a soft pack of individually segregated unit dosages of medication. The opener or soft pack puncturing mechanism has a base segment and a top segment hingedly connected to one another. The base segment has an orifice located thereon which is of sufficient size to receive a unit dosage section of a soft pack commonly referred to as a "blister" and the top segment has a protrusion adapted to nest within the orifice of the bottom segment. The protrusion of the top segment has sufficient height so as to puncture a dosage unit section of a soft pack of medication. When a dosage unit or "blister" is placed within the orifice of the bottom segment and the top segment is hingedly pushed downwardly, the protrusion on the top segment will puncture the foil or flat element of the blister pack. Preferably, the puncture mechanism has toothed edges on this protrusion to enhance puncturing.

  • Patent number: 5829658
    Abstract: A method and a device are provided for obtaining semiconductor bars for laser devices starting from portions of a processed wafer and carrying out the cleavage in ultra-high-vacuum. The cleavage mechanical stresses are impulsive forces and are all applied from the processed side of the wafer through a lowerable shaped member actuated by compressed helical springs, which applies these stresses on the ledging parts of the wafer portion held on a central region thereof by a fixed support and held down in position by a suitably shaped centering thrust member. The spring-up occurs by translating the device in the ultra-high-vacuum environment and opposing a locking lever engaging the lowerable member in an upper or first position with a fixed cam.

  • Patent number: 5820006
    Abstract: Apparatus for automatic scribing and breaking of semiconductor wafers wherein scribing is performed at a scribing station and the scribed wafer transported in the X direction to a breaking station on an X-Y table. Scribing and breaking of parallel lines is accomplished by transporting the wafer step-wise in the Y direction by the Y table. Rotation of the wafer for scribing and breaking along sets of lines perpendicular to one another is accomplished by a theta table carried on the Y table. An impulse bar is carried by the X table for applying force to the bottom surface of the wafer during both scribing and breaking. In one embodiment, upward movement of the wafer during breaking is resisted by an anvil positioned above the wafer. In a second embodiment, such upward movement is resisted by a vacuum chuck beneath the wafer, to avoid contact with the upper wafer surface.

  • Patent number: 5791539
    Abstract: Method and apparatus for separating a bundle of blank pieces from a stack of sheets. The apparatus has a frame and a subframe which pivots with respect to the frame. The frame and subframe each have a clamp for clamping the stack of sheets along a stack plane and the bundle portion to be separated from the stack along a separation plane that intersects the stack plane. The subframe pivots with respect to the frame, bending the stack to cause the bundle portion to be separated from the remainder of the stack in such a way that separation is initiated at one point along the stack rather than across the whole stack or across an entire sheet of the stack. The subframe pivots about an axis that is skewed with respect to at least one of the planes to produce the described effect.

    Abstract: A wafer to be diced to form chips is placed on the sticky side of a thin elastic film in the form of a Swiss Cross which is secured to the side members of a compressed but expandable square frame, the frame being placed in a scribing and dicing machine in its released state so that the frame and thus the film can expand during the dicing operation, further expansion being accomplished after dicing of the wafer by heating the film while in an expansion fixture to insure removal of the chips from the film without damaging adjacent chips. The sticky material on the film may be rendered less sticky after formation of the chips by exposure to ultraviolet energy or the like.
