Processing device for ultrasonic grinding sapphire lens

Abstract

A processing device for ultrasonically grinding sapphire lenses, including a support (18) and an ultrasonic vibration loading system, the support (18) is provided with a workbench (17) and a machine bed (2), and the machine bed (2) is There is a grinding head drive system and a grinding liquid supply system located above the workbench (17). The workbench (17) is equipped with a lens fixing system. The support (18) is provided with a Auxiliary motion system for horizontal movement in the direction and Y direction and lifting movement in the Z direction. The invention has the advantages of advanced technology, relatively low processing cost, high production efficiency and good processing quality, fully utilizes the advantages of existing machine tools and vacuum suction cups in the research institution, and can efficiently and high-quality sapphire lenses that are getting hotter and hotter. Grinding to meet the needs of future enterprises.

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 gl...

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. After cutting, the surface needs to be polished on both sides for 2-3 hours 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
