Grinding technology for optical filter

Abstract

The invention relates to the field of lens manufacturing, in particular to a grinding technology for an optical filter. According to the grinding technology, a first fastening mechanism, a second fastening mechanism, a first cutting mechanism, a second cutting mechanism, a first grinding mechanism and a second grinding mechanism are arranged; the first fastening mechanism comprises a first air cylinder and two first fastening units; the second fastening mechanism comprises a second air cylinder and two second fastening units; arc-shaped through grooves are formed in the inner side walls of fastening blocks; Y-shaped through holes are formed in the middle of the fastening blocks in the radial direction; the first cutting mechanism comprises a first supporting rod, a first pushing rod, two first adjusting rods and two first cutters; the second cutting mechanism comprises a second supporting rod, a second pushing rod, two second adjusting rods and two second cutters; the first grinding mechanism comprises a first motor and a first grinding disc; and the second grinding mechanism comprises a second motor and a second grinding disc. According to the technical scheme of the grinding technology, double-sided grinding can be simultaneously carried out on the round optical filter, and meanwhile, the cutting operation can be completed.

Description

technical field [0001] The invention relates to the field of optical filter processing, in particular to an optical filter grinding process. Background technique [0002] The main raw material of the optical filter is optical glass, and its refractive index is higher than that of the resin lens. Therefore, under the same degree of power, the optical filter is thinner than the resin lens. The light transmittance and mechanical and chemical properties of the filter are relatively good, with a constant refractive index and stable physical and chemical properties. [0003] In the process of processing the circular filter, the circular filter needs to be polished. The traditional grinding method is generally to polish it by manually holding the circular filter. Since the circular filter is not fixed, there are defects of poor grinding effect and long grinding time. In order to solve the above defects, the most commonly used grinding method at present is to absorb and fix one si...

AI Technical Summary

Problems solved by technology

This kind of grinding method improves the stability of grinding, thereby improving the grinding accuracy, but the efficiency has not been effectively improved; at the same time, in order to facilitate subsequent installation and use, the circular filter needs to be chamfered after the double-sided grinding is completed, resulting in Processing procedures are cumbersome
