Problems solved by technology

[0004] However, if foreign matter, cullet, and other sundries of the equipment are sandwiched between the glass substrate adsorption table and the glass substrate, the glass substrate adsorbed on the glass substrate adsorption table will be scratched due to the high adsorption force. scratches, resulting in a problem of deteriorating the quality of the glass substrate
In addition, when the scratches are found on the glass substrate after the polishing process in the latter stage of the process, there is a problem that many glass substrates produced until the scratches are found become defective.

Embodiment Construction

[0033] Hereinafter, preferred embodiments of the glass substrate adsorption table and the glass substrate processing method of the present invention will be described with reference to the drawings.

[0034] figure 1 (A) to (C) are explanatory diagrams showing the structure of the glass substrate suction table 10 of the glass substrate processing machine according to the embodiment, and the left figures of (A) to (C) respectively show a plan view of the glass substrate suction table 10, and the right The figures each show a side sectional view of the glass substrate adsorption table 10 . The glass substrate suction table 10 is a table set on a glass substrate edger, figure 1 Among them, three stages 12 , 14 , and 16 divided into elongated rectangular shapes are configured as a planar rectangular shape corresponding to the shape of the glass substrate G as a whole. In addition, the number of divisions of the glass substrate adsorption stage 10 is not limited to three, and m...

Abstract

Disclosed is a sheet material (18) which is intended to be adhered to a glass substrate suction table for a glass substrate-processing machine. The sheet material (18) has a hardness of 90 to 95 degrees in accordance with JIS K6253 or JIS K7215, a thickness of 0.7 mm or less, and a coefficient of kinetic friction of 0.3 or less. Preferably, the sheet material (18) has a multi-layered structure composed of at least a urethane sheet material (32) and an olefin sheet material (or a nitflon sheet material) (34), and has a total thickness of 0.7 mm or less.

Description

technical field [0001] The invention relates to a glass substrate adsorption table and a glass substrate processing method, and relates to a glass substrate adsorption table and a glass substrate processing method for adsorbing and holding a glass substrate to be edged through a sheet. Background technique [0002] For glass substrates for FPD (Flat Panel Display: Flat Panel Display) such as liquid crystal displays and plasma displays, the glass plate is cut and broken into a predetermined rectangular shape and size in the cutting and breaking process, and the edges are edged in the edging process. Thereby, the glass substrate of the external dimension of a product is manufactured. Then, the glass substrate is transferred to the surface polishing step through the cleaning step and the inspection step provided after the edging step, where a glass substrate having a product thickness is produced. [0003] In the manufacturing process of such a glass substrate, when cutting an...
