Feeding device used for grinding and thinning double end faces of hard and brittle material

Abstract

The invention discloses a feeding device used for grinding and thinning double end faces of a hard and brittle material. The device comprises a hard and brittle material sheet feeding mechanism, an intermediate following mechanism, a feeding turntable and a central rotating seat, wherein the central rotating seat is arranged on a grinding machine, the feeding turntable is arranged on the central rotating seat and rotates along with the central rotating seat, the intermediate following mechanism is arranged on the central rotating seat and is intermittently driven by the feeding turntable to follow, and the hard and brittle material sheet feeding mechanism is fixed on the grinding machine and butted with the intermediate following mechanism. The feeding device has the advantages of accuratefeeding, low cost, capability of pushing hard and brittle material sheets one by one and capability of improving the production efficiency.

Description

technical field [0001] The invention relates to the technology of grinding and thinning the double-end surfaces of superhard and brittle materials, in particular to a feeding device for grinding and thinning the double-end surfaces of hard and brittle materials. Background technique [0002] Nowadays, everyone has a smart phone, and the screen of the mobile phone is getting bigger and bigger. Most of the screens of smart phones are made of optically hard and brittle materials. There are two hard and brittle material thinning processes in the processing technology of hard and brittle materials such as new panels and sapphire. This optical hard and brittle material thinning process is generally thinned by double-end grinding machines. Generally, it will be thinned from 1.1mm to about 0.8mm. Due to the hard and brittle characteristics of optically hard and brittle materials, the processing efficiency in the regrinding process is very low. Therefore, the thinning process in th...

AI Technical Summary

Problems solved by technology

[0003] At present, the grinding process of hard and brittle materials on mobile phone panels uses double-end grinding machines to thin hard and brittle materials. Problems 1. It is cumbersome and difficult to replace the abrasive of the double-end grinding machine; 2. The labor intensity is high and requires a high level of operator skills ; 3. It is difficult to realize automatic loading and unloading and in-line production
