Description

Technical Field

[0001] The utility model relates to the technical field of optical lens processing, in particular to an optical lens edge grinding device. Background Art

[0002] Optical lenses are transparent materials made from optical materials such as optical glass or plastic, often with curved surfaces. Optical glass has specific requirements for optical properties such as refractive index, dispersion, transmittance, spectral transmittance, and light absorption, and its optical properties are uniform.

[0003] Optical lens edging is a critical process in the eyewear manufacturing and optical industries. It involves cutting and trimming optical lens blanks to specific shapes, sizes, and surface quality requirements. Existing edging processes often rely on manual loading, which cannot quickly determine the position of the lens. Furthermore, during processing, the lens is polished with a single grinding disc, which cannot separate the coarse and fine grinding of the lens. A single grinding disc cannot simultaneously meet the different process requirements of coarse and fine grinding. During the coarse grinding stage, if the grinding disc is too fine, the processing efficiency will be low; while during the fine grinding stage, if the grinding disc is too rough, the required surface finish cannot be achieved.
