Problems solved by technology

However, when damage and waviness are locally generated deeper than the predetermined amount, there is a problem that the damage and waviness cannot be removed by polishing and remain (hereinafter referred to as "grinding residue").
In addition, local damage may occur during grinding and transportation
When grinding residue and damage occur, the entire surface of the glass plate G is ground again by the grinding device 100, so the efficiency is low.

Abstract

The invention provides an apparatus and a method for locally polishing glass plates, and an apparatus and a method for producing glass products, wherein grinding quality is stable and the production efficiency is increased.After the defects on the surface of a glass plate (G) are detected by a detection unit (4), the glass plate (G) is adsorbed and fixed to a work table (2).The positions of the defects (D) detected by the detection unit (4) and the surrounding place are polished by a polishing pad (34) with a smaller dimension compared with the glass plate (G), thereby removing the defects (D) without polishing the whole surface of the glass plate.

Description

technical field [0001] The present invention relates to a glass plate partial grinding device, a glass plate partial grinding method, a glass product manufacturing device, and a glass product manufacturing method, which use a grinding pad to grind the surface of a glass plate adsorbed and fixed on a workbench. Background technique [0002] In the manufacture of plate glass products used for flat panel displays, etc., the molten glass melted by the molten glass manufacturing device is formed into a glass ribbon by the forming unit, and the formed glass ribbon is slowly cooled by the slow cooling unit, thereby producing into a glass plate. The slowly cooled glass plate is cut into a glass plate of a predetermined shape by the cutting unit, and the micro damage and ripples on the surface are removed by a grinding device to make a plate-shaped glass product. Carry out the polishing device of glass plate in the polishing device that is provided with the workbench that adsorbs an...
