Lens chamfering device

Abstract

The invention discloses a lens chamfering device. The lens chamfering device comprises a conical grinding wheel making contact with a lens and used for chamfering the lens, a drive unit connected withthe conical grinding wheel and for driving the conical grinding wheel to linearly move and rotate, and an adjusting unit which makes the area of the contact face of the lens and the conical grindingwheel be adjustable. In this mode, the area of the contact face of the lens and the conical grinding wheel can be adjusted by the adjusting unit, so that the chamfering size and angle are adjusted, the lens is chamfered through the conical grinding wheel, multiple times of replacement is not needed, and the lens chamfering precision is ensured; and the drive unit not only drive the conical grinding wheel to rotate, but also can make the conical grinding wheel to linearly move, the chamfering angle is changed, chamfers of different angles can be machined, and universality of the whole device isimproved.

Description

technical field [0001] The invention relates to the technical field of lens processing, in particular to a lens chamfering device. Background technique [0002] For the optical processing technology of the chamfering of rectangular lenses or polygonal lenses, sandpaper flat discs or diamond flat discs are generally used to process the chamfering of flat lenses in a straight line; in order to improve efficiency, multiple lenses can be bonded into a row, or clamped In a row, chamfering processing. Of course, CNC equipment is also used to process linear chamfering with diamond grinding heads, but this processing method is expensive and economical. [0003] The traditional lens chamfering process is a flat disc or a diamond flat disc pasted with sandpaper. Sandpaper is easy to be damaged in the water environment, and needs to be replaced frequently, and the processing accuracy and efficiency are relatively low; the efficiency of diamond flat disk is higher than that of sandpap...

AI Technical Summary

Problems solved by technology

Sandpaper is easy to be damaged in the water environment, and needs to be replaced frequently, and the processing accuracy and efficiency are relatively low; the efficiency of diamond flat disk is higher than that of sandpaper, and it does not need to be replaced and maintained frequently, but the economy is poor

Both of these methods require high requirements for operator skills, large dimensional fluctuations, and it is difficult to obtain ideal accuracy and dimensional consistency.
