Description

Technical Field

[0002] An optical lens is an optical element used to aggregate or disperse light. It can be widely used in various fields such as automobiles, security, digital cameras, lasers, optical instruments, etc. Optical lenses are generally concave lenses or convex lenses. Some optical lenses need to be polished on their edges during the processing process. In the existing optical lens polishing device (such as a circular plane lens edge polishing device disclosed in application number 201721179351.9), during the polishing process of the optical lens, the lens is fixed by a clamping mechanism, and the clamping mechanism is driven to rotate by a motor to drive the lens to rotate.
