Description

Technical Field

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

[0002] With the development of optics, optical lenses are used more and more widely. During the processing of optical lenses, it is usually necessary to mark the optical lenses to prevent different models of optical lenses from being mixed up. Optical lens laser marking refers to marking the frame with a laser device. This laser marking allows insiders and consumers to better identify frame materials and related information.

[0003] When an existing optical lens laser marking device performs laser marking on a circular optical lens, it is difficult to accurately position the optical lens because the optical lens is relatively smooth, which may cause deviation in the position of the laser mark on the optical lens and affect the marking effect of the optical lens.

[0004] To this end, we propose an optical lens laser marking device. Utility Model Content
