Description

Technical Field

[0001] This utility model relates to the field of optical lens processing technology, specifically a high-precision cutting device for optical lens processing. Background Technology

[0002] With the rapid development of modern technology, optical lenses are increasingly widely used in many fields, such as photography, medical imaging, aerospace, virtual reality, and smartphones. These fields have increasingly higher requirements for the precision, surface quality, and performance of optical lenses, driving the continuous development of optical lens processing technology towards higher precision and higher efficiency.

[0003] When optical lenses are processed, they need to be cut. During the cutting process, the optical lenses need to be fixed. However, the existing clamping mechanism usually consists of two planes that fit against the two sides of the optical lens to fix it. Some optical lenses have a certain curvature when they are cut, which can cause the lens to break during clamping, affecting the cutting of the optical lens. Utility Model Content
