Liquid crystal glass substrate thinning etching equipment

Abstract

The invention discloses liquid crystal glass substrate thinning etching equipment, and the equipment comprises a mounting device used for mounting a glass substrate and a spraying device used for spraying etching liquid; the mounting device comprises a pivot end and a free end which are oppositely arranged, the free end rotates with the pivot end as the axis, so the inclination angle of the glass substrate arranged on the mounting device is changed; the spraying device is arranged at the upper part of the upper end of the inclined glass substrate and uniformly sprays etching liquid to the glass substrate from the upper end of the inclined glass substrate. According to the liquid crystal glass substrate thinning etching equipment, by inclining the liquid crystal glass substrate, on one hand, one face of the liquid crystal glass substrate can be thinned, on the other hand, etching liquid flows on the surface of the liquid crystal glass substrate, white powdery precipitates and the like generated by reaction are washed, and the surface quality of the thinned liquid crystal glass substrate is improved.

Description

technical field [0001] The invention belongs to the field of production equipment for liquid crystal glass substrates, and more specifically relates to thinning and etching equipment for liquid crystal glass substrates. Background technique [0002] With the development of portable electronic devices, electronic devices such as mobile phones, tablets, TVs, and computers are becoming more and more slim and thin. Therefore, thinner and ultra-thin glass substrates are required as accessories. There are two main ways to obtain ultra-thin glass substrates. One is to directly produce ultra-thin glass. The ultra-thin glass obtained in this way requires high production and processing technology and equipment, and the production cost is high. Most manufacturers cannot produced, and the produced ultra-thin glass needs to be protected by a carrier during transportation. In the production of glass substrates, it is necessary to process the glass and the carrier at the same time to form ...

Problems solved by technology

However, in the multi-piece vertical immersion thinning method, the white powdery precipitate produced by the reaction is easy to deposit and adhere to the lower end of the glass substrate, which will cause the lower end of the glass to be uneven and not smooth, which will affect the product quality.
