  • Patent number: 10131564
    Abstract: A glass plate separating apparatus, as one example, includes: a trigger device that forms a start point flaw in a first main surface of a glass ribbon on a division-planned line; a pair of holding members disposed at the first main surface side of the glass ribbon; and a heater disposed at a second main surface side of the glass ribbon. The pair of holding members, each of which extends parallel to the division-planned line, is brought into contact with the glass ribbon at both sides of the division-planned line while being lowered together with the glass ribbon. The heater extends along the division-planned line, and is brought into contact with and pressed onto the glass ribbon on the division-planned line while being lowered together with the glass ribbon.

  • Publication number: 20160151929
    Abstract: A method of dividing a plate member made of a brittle material includes; first, forming a minute start point flaw 16 in a first main surface of a plate member on a division-planned line; then holding the first main surface of the plate member on a pair of lines; and thereafter, for example, bringing a dividing member, which heats up a second main surface of the plate member by contact heating, into contact with the second main surface of the plate member to generate a tensile thermal stress on the first main surface and applying bending force in a thickness direction of the plate member to the second main surface of the plate member, such that a tensile stress derived from the bending force and the tensile thermal stress are combined together. In this manner, the plate member is divided along the division-planned line.

  • Patent number: 9114935
    Abstract: The present invention provides a plate member conveying apparatus configured such that an occupied area is small, and a plate member is unlikely to be damaged. A plate member conveying apparatus according to the present invention includes a feed device having a conveying portion and a pressurizing portion. The conveying portion includes a belt configured to contact one of surfaces of a plate member in a vertical state to feed the plate member in a conveying direction. The pressurizing portion applies pressure of a fluid to the other surface of the plate member in the vertical state in a direction perpendicular to the surface of the plate member to press the plate member toward the belt. Then, the plate member in the vertical state is conveyed while being held by sandwiching the plate member between the belt of the conveying portion and the fluid of the pressurizing portion.

  • Patent number: 9079226
    Abstract: A high-pressure liquid jet cleaner removes particles adhered to the inside of scribe lines formed at consistent intervals in a thin film solar cell panel and prevents the surface of a thin film formed at the surface of the solar cell panel from being damaged or detached. Jet nozzles are arranged at consistent intervals in the longitudinal direction of a nozzle holder, corresponding to positions of the respective scribe lines. The nozzle holder is supported by supports provided at both ends of the nozzle holder to allow the nozzle holder to move in the longitudinal direction. While the solar cell panel is conveyed parallel to the scribe lines, a high-pressure liquid is jetted out in a straight line from the jet nozzles to the respective scribe lines for cleaning, such that the high-pressure liquid jetting direction of each jet nozzle is parallel to that of the other jet nozzles.
