Processing device for ultrasonic grinding on sapphire lenses

Abstract

The invention discloses a processing device for ultrasonic grinding on sapphire lenses. The processing device comprises a support seat (18) and an ultrasonic vibration loading system, wherein a working table (17) and a machine tool body (2); a grinding head driving system and a grinding liquid supply system which are located above the working table (17) are arranged on the machine tool body (2); a lens fixing and mounting system is arranged on the working table (17); the support seat (18) is provided with an auxiliary moving system used for controlling the working table (17) to horizontally move in an X direction and a Y direction and move up and down in a Z direction. The processing device for the ultrasonic grinding of the sapphire lenses has the advantages that the process is advanced, the processing cost is relatively low, the production efficiency is high, the processing quality is high, and an existing machine tool device and an existing vacuum sucking disc of a research institute are fully utilized; the processing device can be used for grinding and processing the sapphire lenses with increasingly high temperature at high efficiency and high quality; the requirements of enterprises in the future are met.

Description

technical field [0001] The invention belongs to the technical field of ultrasonic vibration grinding processing, in particular to a processing device for ultrasonic grinding sapphire lens. Background technique [0002] As the word sapphire appears more and more in the hardware parameters of some new products, the popularity of "sapphire" has begun to heat up sharply, and it is rumored that a certain major brand mobile phone will use sapphire glass screen, which further improves the quality of sapphire raw materials. heat. The data shows that the hardness of sapphire has reached Mohs 9, second only to diamonds, and has dozens of times higher hardness and abrasion resistance than ordinary glass. Using sapphire raw materials to make camera lenses or mobile phone screens can greatly improve the camera performance. Excellent anti-scratch and wear-resistant properties to ensure clear imaging. Due to the performance advantages of sapphire compared with ordinary glass, sapphire g...

AI Technical Summary

Problems solved by technology

Due to the performance advantages of sapphire compared with ordinary glass, sapphire glass is widely used in mobile phones and other mobile electronic products, and there will inevitably be a shortage of sapphire resources. The reason is mainly determined by its processing technology: when processing sapphire lenses , Surface treatment is one of the biggest bottlenecks in production capacity. The cut surface needs 2-3 hours of double-sided polishing to achieve >90% light transmittance. The characteristics of sapphire processing make it impossible to have as many resources as ordinary glass. , and no effective alternative processing technology has been developed at present, so it is of great significance to invent a new type of processing technology and device for sapphire lenses
