Cutting process method of touch screen

Abstract

The invention discloses a cutting process method of a touch screen. The touch screen is OGS (one-glass solution) large glass which is formed by integrating a glass cover plate and a touch screen sensing module and processed via chemical reinforcement. The cutting process method comprises the following steps: 1) adopting the laser control fracture method or the laser invisible cutting method to cut the OGS large glass along the set horizontal line and vertical line, after cutting, the OGS large glass is enabled to keep complete and large, wherein the set horizontal line and vertical line divided the OGS large glass into a plurality of small glass units; 2) adopting the laser ablation method to cut the OGS large glass along the set curve, so as to cut lead angles and internal through holes of each small glass unit in the OGS large glass; 3) sending the whole OGS large glass to an automatic break machine or manually breaking the glass, thereby separating out each small glass unit. By virtue of the cutting process method, the efficiency of the cutting process is higher, the yield is higher, and the productivity is improved, and at the meantime the cost for the cutting process is lower.

Description

【Technical field】 [0001] The invention relates to a processing method for electronic products, in particular to a cutting and processing method for a touch screen. 【Background technique】 [0002] With the rapid development of touch screen technology, it has been applied to every corner of daily life, such as smartphones, digital cameras, tablet computers, car navigators, ATM machines, subway ticket machines, number calling machines in public places such as banks and administrative departments, shopping malls, hospitals and hotels Interactive indication screens in service places such as mobile phones, various large-screen demonstration equipment used by news media, etc., have become an indispensable part of daily life. There are many types of touch screen technologies, such as surface acoustic wave type, infrared type, resistive screen, capacitive screen, etc. From the comparison of their performance indicators, the capacitive touch screen has the greatest advantage, so it is...

AI Technical Summary

Problems solved by technology

[0005] However, due to the high hardness of glass after chemical strengthening, it is more difficult to cut by the knife wheel in the above cutting method

After the glass is chemically strengthened, the Mohs hardness can reach 7.2-8.5. The usual cutter wheel is a superhard alloy cutter wheel or a diamond cutter wheel. The Mohs hardness is 9-10. Although it can be cut, the cutter wheel is easy to cut because of the hard glass. Slipping, if the pressure of the cutter wheel is increased during cutting or the cutting parameters are not well controlled, it is easy to cause the entire piece of the product to break, resulting in a low yield rate of the product during cutting by the cutter wheel (at present, the yield rate of different manufacturers is different, most of them are about 50~ 70%), resulting in serious waste, increased costs, and limited production capacity

At the same time, both the cutter wheel and the grinding head are consumables, and there is loss in each cutting process, which further increases the cost
