Problems solved by technology

The production of domestic high-precision lenses is mainly realized by expensive imported equipment, which seriously restricts the production and supply of domestic products
[0003] CN2564303Y discloses an automatic control system for precise grinding and thickness determination of optical lenses, which mainly relies on the control of pressurized cylinder pressure to increase the thickness of optical lenses for fine grinding. The control is even more difficult, which will easily lead to poor product quality and reliability; 2) Due to the difficulty of air pressure control, especially when used for the processing of brittle material lenses, the lens is easy to break, which will lead to a decrease in yield; 3) The system has many components , the structure is more complicated and the manufacturing cost is higher

Description

technical field [0001] The invention relates to the technical field of optical lens production, in particular to a grinding thickness control device of an optical lens. Background technique [0002] In the process of optical lens grinding, the most difficult and most important is the precise control of the thickness of the lens and the pressure of the grinding head, especially the grinding of precision optical instruments and lenses with brittle materials. Two factors are the bottleneck processes that plague the production of enterprises. Therefore, imported products still occupy a dominant position in the market for the matching of precision optical instruments and lenses with brittle materials. The production of domestic high-precision lenses also mainly relies on expensive imported equipment, which seriously restricts the production and supply of domestic products. [0003] CN2564303Y discloses an automatic control system for fine grinding and thickness determination of ...
