Description

  The present invention relates to a tray for conveying a plate-shaped article, and relates to a glass plate, for example, a square or rectangular substrate such as a display glass substrate used for forming a display panel of a liquid crystal display device, or a metal thin plate that is easily bent by its own weight. It is used to transport, transport, and stack the plate-shaped articles to be transported, and responds to bending of the articles to be conveyed by using the tension of the linear member stretched on the inner area of the frame. Support and open the back of the frame.

  Conventionally, a display panel of a liquid crystal display device is usually formed by encapsulating liquid crystal between a pair of display glass substrates arranged to face each other. When such a display panel is manufactured in a factory, a glass substrate for display is transported to the display panel manufacturing factory. The glass substrate is used not only for the display panel of a liquid crystal display device but also for the manufacture of display panels for various display devices.

  In addition, in order to obtain a display panel, there is a semi-finished display panel in which electrodes and the like are formed on the surface of a glass substrate.

  Recently, glass substrates having a thickness of 0.7 mm or less have been used for various display panels. In addition, with the increase in the size of the display panel, the glass substrate carried into the manufacturing factory is also enlarged, and a rectangular glass substrate having a side of 1.3 m or more is also carried into the factory.

  Since a thin glass substrate having such a large area is easily bent, conventionally, for example, a plurality of glass substrates are vertically spaced apart from each other in a glass substrate storage box. Although there is a method of storing in a state, each glass substrate is bent at the time of transportation, and adjacent glass substrates may come into contact with each other and be damaged. For this reason, it is necessary to arrange | position in the glass substrate storage box at intervals so that each glass substrate accommodated may be bent and it may not mutually contact.

  For example, when a glass substrate having a thickness of 0.7 mm and a side length of 1.3 m or more is vertically supported with a side edge of 20 to 30 mm in width, the deflection at the center of the glass substrate is 90 mm or more. become. For this reason, it is necessary to hold | maintain glass substrates at intervals of at least 100 mm or more in a horizontal direction within a glass substrate storage box.

  Moreover, when taking out a glass substrate from a glass substrate storage box, the glass substrate suction hand which has a pair of flat suction pad is used normally. When using such a glass substrate suction hand, it is necessary to insert each suction pad between adjacent glass substrates, and a space for that purpose is also required. Each of the flat suction pads has a thickness of about 20 mm. Therefore, it is necessary to provide an interval between adjacent glass substrates so that the glass substrates do not contact each other even if they are bent, and further, an interval of about 20 mm for inserting the suction pad.

  Since the plurality of glass substrates stored in the glass substrate storage box need to have an appropriate interval, the number of glass substrates that can be stored in the glass substrate storage box of a predetermined size is Decrease. As a result, there is a problem in that the number of glass substrates with respect to the space occupied by the glass substrate storage box is reduced during transportation and storage, and the space efficiency is lowered.

  Furthermore, a glass substrate having a large area with a side length of 1.3 m or more is as heavy as about 5 kg, and when the number of glass substrates stored in the glass substrate storage box becomes 20 or more, There is a problem that it cannot be transported or transported by one person.

Thus, in order to solve the problem of the glass substrate storage box, conventionally, for example, a substrate tray cassette for storing one glass substrate has been proposed. This tray cassette for a substrate forms a lattice-like basic structure with a peripheral frame arranged on the front, rear, left and right sides and a crosspiece spanned between the peripheral frames, and a left peripheral frame and a right peripheral frame among the peripheral frames And the rear peripheral frame forms a main frame of an intricately engaging structure that enables stacking of trays, and the front peripheral frame of the peripheral frames and the crosspieces constitute subframes. Further, the main frame is provided with an overhang member that projects from the inner side surface of the main frame or the bottom surface of the main frame at a position lower than the upper surface. A resin pin for supporting the substrate from below is provided on the projecting member and the subframe attached to the main frame so as to project upward from below. Further, there is one in which a bottom plate can be provided at the bottom of a grid-like tray (for example, see Patent Document 1).
JP 10-287382 A

  However, in the conventional substrate tray cassette described in Patent Document 1, the glass substrate accommodated in the tray cassette protrudes on the protruding member and the subframe attached to the main frame of the lattice-shaped tray cassette. Because it is supported by point support scattered from below by a large number of resin pins, it is thin and large in area, and supports the glass substrate by preventing large deflection at the center of the glass substrate that is heavy. It was not enough.

  Further, the glass substrate supported on the resin pin is easily slid on the resin pin, and is easily damaged by colliding with the inner surface of the peripheral frame.

  And since a big stress concentrates on the center part, the glass substrate may be damaged or hooked during transportation or storage, or may be cracked. In addition, the glass substrate is liable to cause inconveniences such as scratches due to contact with the crosspieces and bottom plate of the substrate tray cassette, resulting in poor yield.

  In addition, the conventional substrate tray cassette described in Patent Document 1 forms a lattice-like basic structure with a peripheral frame arranged on the front, rear, left and right sides, and a crosspiece spanned between the peripheral frames. The left peripheral frame, the right peripheral frame, and the rear peripheral frame form a main frame, the front peripheral frame of the peripheral frames and the crosspiece form a subframe, and the lower surface is closed by a bottom plate. Therefore, the tray cassette has a structure in which the glass substrate is supported by the projecting resin pins provided on the projecting members and the subframes attached to the main frame of the lattice-shaped tray cassette. The sum of the height, the thickness of the glass substrate, the clearance corresponding to the large deflection at the center of the glass substrate, and the thickness of the bottom plate corresponds to the height of the tray cassette. Therefore, the height of the peripheral frame of the tray cassette is increased, the tray cassette itself is forced to be enlarged, and the weight is also increased.

It is a thin and large area, supports a glass plate by reliably preventing a large deflection at the center of a heavy glass plate, Or during storage, the glass plate is not damaged or cracked, the yield is good, the tray itself is thinned, it is reduced in size and weight, the structure is simple, and it is easy to manufacture and assemble An object of the present invention is to provide a plate-shaped article carrying tray.
