Example Embodiment

[0044] Hereinafter, preferred embodiments of the glass plate partial polishing device, the glass plate partial polishing method, the glass product manufacturing device, and the glass product manufacturing method of the present invention will be described based on the drawings.

[0045] The local polishing device 1 includes: a table 2 holding a glass plate G; and a plurality of units ( figure 1 Only one of the grinders 3 and 3 is shown in the figure. In addition, such as figure 2 (a) or figure 2 As shown in (b), the local polishing device 1 includes an optical detection unit 4 based on a laser or the like and a conveying unit 5. The conveying unit 5 is composed of X, Y, and Z moving shafts and suction arms. Controlled by the control unit 6. The whole surface polishing device 7 is arranged at the position of the pre-process or post-process of the partial polishing device 1.

[0046] As the entire surface polishing device 7, an entire surface polishing device that performs polishi...

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...
