Glass substrate loading cassette for adjusting interval between slot bars

Abstract

A glass substrate loading cassette for adjusting an interval between slot bars is provided. The glass substrate loading cassette comprises an interval adjusting device used for adjusting the interval between slot bars according to sizes of glass substrates. The interval adjusting device comprises first and second rails arranged to be parallel at a constant interval, first and second moveable members installed to be movable along the longitudinal direction of the first and second rails and configured to install the slot bars, a plurality of guide blocks sleeved to the movable members for guiding to prevent the movable members from derailing from tracks of the rails, a screw shaft rotatably installed between the first and second rails and provided with a left screw portion on the periphery of one side and a right screw portion on the periphery of the other side, and a rotating member rotates the screw shaft. One movable member is sleeved to the left screw portion and the other movable member is sleeved to the right screw portion.

Description

technical field [0001] The invention relates to a glass substrate loading cassette with adjustable spacing between groove bars. [0002] In particular, it is characterized in that glass substrates of different sizes can be exchanged in one cassette, and the moving means of the groove bar is improved to a non-lubricating method, so that compared with lubrication methods such as ball bushings, pollution caused by lubricating oil leakage can be prevented A glass substrate loading cassette with adjustable spacing between slot bars. Background technique [0003] The substrates of flat-panel displays such as LCDs (hereinafter referred to as "glass substrates") are made of glass, which is brittle and needs to be handled with care. This is especially true for large glass substrates with large dimensions. Therefore, in order to prevent breakage, the glass substrate is protectively carried in a cassette (cassette) for a series of display manufacturing processes. [0004] figure 1 ...

AI Technical Summary

Problems solved by technology

[0008] But in above-mentioned prior patent, the upper end and the lower end of side bar (30) are fixed on the long hole (11,21) by screw (31) and clamping nut (33), the displacement and fixing of side bar (30) , need to loosen and tighten the clamping nut (33), the process is cumbersome

[0009] In addition, in the above-mentioned prior patent, when the fixed positions of the top and bottom of the side bar (30) are different from each other, the side bar after installation may be oblique, and it is difficult to install it correctly, which may result in failure to stack glass substrates ( P)

[0010] In addition, in the above-mentioned prior patents, the length of the long holes (11, 21) is not too long, and the variable range of the side bar (30) is limited
