A processing device for ultrasonic grinding sapphire lens

Abstract

The invention discloses a machining device for ultrasonic grinding of a sapphire lens. The device comprises a support and an ultrasonic vibration loading system; a worktable and a machine tool lathe bed are fixedly arranged on the upper portion of the support, a grinding liquid box is fixedly arranged on the front side of the machine tool lathe bed, the middles of the upper end face and the lowerend face of the grinding liquid box are provided with first through holes, a vertical pipe is arranged in the first through holes through a seal bearing, the upper end and the lower end of the vertical pipe are closed, a driven belt wheel is fixedly arranged on the upper end of the vertical pipe, a vertical motor is fixedly arranged on the front side of the machine tool lathe bed, a driving belt wheel is fixedly arranged on an output shaft of the motor, and the driving belt wheel and the driven belt wheel are connected through a transmission belt. Compared with an existing lens machining device, the structure is simpler, multiple workpieces can be machined at the same time, a grinding liquid supply system is arranged, grinding liquid flowing out operation has the automatic rotating speed adjusting function, a rotating shaft of a grinding head can be automatically and slightly changed along with rotating speed changes of the motor, and the relative position of the grinding head can be changed at any time in the sapphire lens grinding process.

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 9 on the Mohs scale, second only to diamonds, and has dozens of times higher hardness and friction resistance than ordinary glass. Using sapphire raw materials to make camera lenses or mobile phone screens can greatly improve the performance of the camera. Scratch-resistant and wear-resistant performance to ensure clear imaging. Due to the performance advantages of sapphire compared with ordinary 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. 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

[0003] The traditional sapphire lens processing device has a complex structure and requires an additional abrasive liquid supply device. It is difficult for the abrasive liquid to automatically adjust the liquid supply speed according to the different working speeds of the processing device. There are slight fixed grinding marks on the surface of the lens, which is not conducive to the high-precision processing of the lens. The traditional processing device is inefficient and difficult to meet the needs of all walks of life.
