Problems solved by technology

[0002] Optical prisms are widely used in cameras, DV, scanning, projection and other instruments. With the development of the market, the demand for optical prisms is increasing. In related technologies, cold glue is used in the processing of optical prisms Bonding lens and glass tooling, and when separating the lens and glass tooling, it needs to be soaked in acetone for a long time, and acetone is a hazardous chemical, the risk factor of using acetone is high and the production cost of optical prisms is high; and the glass is separated It is easy to burst and break, and there is a certain danger; in addition, the existing optical prism is easy to cause mirror wear and affect the operation performance during long-term use.

Abstract

The invention discloses a processing method of an optical prism. The processing method comprises the following steps that S1, a resin sheet is cut into polyhedral prismatic sheets; S2, the multiple faces of a resin edge sheet blank are ground; S3, the ground resin edge sheet blank is cleaned; S4, the resin edge sheet blank and the lens are bonded by using glue to form a bonding body; S6, the lensis processed; S7, the bonding body and a milling and grinding table are separated; S8, the lens and the resin edge blank are separated; S9, the separated lens is polished; and S10, the polished lens is plated with a layer of scratch-resistant film. The lens is bonded through the glue, the bonding effect is good, when the resin edge piece blank and the lens are separated, water with different temperatures and glue separating agents is used for alternate soaking, the safety system is high, and each face of a treated prism is plated with a PET film, so that the mirror face is resistant to scratches, and the transparency and the photorefractive property of the mirror face are good; and the mirror face also has tensile strength, impact strength, chemical corrosion resistance and other properties.
