Description

Technical Field

[0001] The utility model relates to the field of coating feeding structures, in particular to a feeding structure of lens coating equipment. Background Art

[0002] Optical lenses play a vital role in various fields. In order to improve the performance of lenses, coating technology is widely used on the surface of lenses. Coating can not only improve the optical properties of lenses, such as reducing reflection and increasing light transmittance, but also enhance its surface hardness and improve wear resistance.

[0003] In the existing optical lens coating automation equipment, the feeding structure is an indispensable part to improve the overall automation rate of the equipment. Due to the physical characteristics of the optical lens, when the optical lens shakes and moves during the feeding process, the mutual friction between the optical lenses will produce irreparable tiny scratches on the optical lens body, affecting the finished product yield. The industry generally adds a separate product isolation mechanism to the feeding structure to avoid this situation. The cost is high, the structure is complex, and the debugging process is cumbersome, which needs to be further simplified. Utility Model Content
