Plate glass surface grinding device and method

Abstract

The invention relates to a flat glass surface grinding device which can meet the processing requirement of large-area flat glass and a grinding method thereof; the grinding device comprises a grinding worktable, a base and a frame, wherein, the grinding worktable is arranged on the guide rail, independently moves along the X direction or along the Y direction and is used for mounting a glass substrate; the base is used for bearing a guide rail; the frame spans over the two sides of the grinding worktable and is fixedly connected with the base; two or more grinding heads are arranged on the frame above the grinding worktable and is driven by a power device to rotate; all grinding heads are arranged on a revolution bracket which is connected with a rotation shaft of a revolution bull gear; the revolution bull gear is meshed with a gear on an output shaft of a revolution driving motor; the rotation shaft of the revolution bull gear is connected with an ascending-descending cylinder of the grinding heads and is driven by the ascending-descending cylinder to ascend and descend; the grinding pressure of the grinding heads are adjusted by the ascending-descending cylinder; even grinding is achieved by the rotation and revolution of a plurality of grinding discs and the motion of the worktable. The grinding device and the grinding method have good grinding efficiency and can be applied to a surface polishing process in the field of liquid crystal glass substrate.

Description

Technical field: [0001] The invention relates to a flat glass surface grinding device and grinding method that can meet the processing requirements of large-area flat glass. Uniform grinding is achieved through the rotation and revolution of multiple grinding discs and the movement of the worktable, and at the same time, it has better grinding Efficiency, especially suitable for the surface polishing process in the field of liquid crystal glass substrates. technical background: [0002] The production of liquid crystal glass is first formed by a special method of molten glass. Due to the principle of thermal expansion and contraction, there will be glass ribs on the surface of the formed glass plate, and there will also be a certain distortion during the forming process, that is, waviness. On the surface of the glass plate, various electrical devices, such as TFT (thin film transistors, etc.), are formed by various processes such as chemical deposition, physical deposition, ...

AI Technical Summary

Problems solved by technology

[0005] However, only a single grinding disc is used in this patent, and the grinding efficiency is still not high, especially not suitable for the production of large glass, and the eccentric rotation mechanism adopted is very complicated, and the equipment is relatively difficult to manufacture. The cost of substrates above G5 is high, and the volume of the grinding head is small The increase is bound to be due to the low rotation speed due to inertia, and it takes a long time to process a large-area glass substrate, and the performance-price ratio is not high
