Grinding device of glass sheet

Abstract

The invention relates to a grinding device (1) of a glass sheet, which is provided with a linear conveying unit (3), a first grinding device and a second grinding device. A glass sheet (2) is linearly conveyed by the linear conveying unit (3) along the X direction, the first grinding device is provided with grinding heads (5 and 6) for respectively grinding two lateral edges (4a and 4b) of the glass sheet (2) which is linearly conveyed by the linear conveying unit (3), and the second grinding device is adjacent to the first grinding device in the X direction and is provided with movable grinding heads (9 and 10) for respectively grinding a front edge (7) and a rear edge (8) extending along the Y direction orthogonal to the X direction in which the glass sheet (2) is linearly conveyed by the linear conveying unit (3).

Description

[0001] This application is a divisional application of the invention patent application with the application number "200710127487.X" and the invention title "glass plate grinding device" submitted by the applicant on June 28, 2007. technical field [0002] The present invention relates to a glass plate grinding machine for grinding the edges of glass plates such as glass plates for plasma displays (PDP), glass plates for liquid crystal displays (LCD), glass plates for solar cells, glass plates for furniture, glass plates for buildings, etc. cutting device. In addition, the present invention relates to a glass plate grinding device for grinding the edges of a glass plate and cutting the corners. In particular, the present invention relates to horizontally conveying a rectangular glass plate, and first simultaneously Grinding device for glass plate that grinds one side and then grinds the remaining opposite sides at the same time, and then cuts the corners of the front and rear ...

AI Technical Summary

Problems solved by technology

[0005] However, in the grinding apparatus of Patent Document 1, since the peripheral edge of the glass plate is ground while reciprocating the glass plate one by one, the glass plate cannot be supplied in a continuous flow operation, and continuous grinding cannot be performed. difficult to increase production

And in this grinding device, there will be a rotating device that will rotate the glass plate 90° between the first device and the second device, and a positioning device and a positioning space will be arranged so that the glass plate coming out of the rotating device is aligned with the second device. Corresponding to the second device, as a whole, the equipment space becomes larger, and the glass plate requires high positioning accuracy of the second device, which requires complicated operations and adjustments during operation
