Abstract

The invention provides an optical lens processing method and device, and an optical lens and relates to the technical field of lens processing. The optical lens processing device comprises a polishingmachine, a processing machine tool and a rigid disk. The rigid disk is detachably connected to the processing machine tool. The rigid disk is provided with a plurality of processing grooves. The polishing machine is detachably connected to the processing machine tool. During processing, the non-processed surfaces of optical lenses are coated with adhesive glue and are attached to corresponding rigid molds, and the rigid molds are clamped to the rigid disk; the rigid disk is mounted on the processing machine tool, and the processed surfaces of the optical lenses are subjected to grinding; andfinally, the optical lenses are discharged from the rigid disk and cleaned. Compared with the prior art, the optical lens processing method provided by the invention has the advantages that the processing effect is good, the optical lenses can be prevented shaking during processing, the quality of the manufactured optical lenses is high, and the rejection rate of the lenses is extremely low.

Description

technical field [0001] The invention relates to the technical field of lens processing, in particular to a processing method for an optical lens, a processing device for an optical lens and an optical lens. Background technique [0002] Under the trend of structural adjustment and industrial transfer of the international optoelectronic industry, the production capacity of optical cold processing in the world has been transferred to China on a large scale. my country has gradually become the manufacturing center of optical cold processing in the world, and the optical manufacturing capacity has exceeded 500 million pieces per year. [0003] Optical lenses need to be made through several steps of cold processing such as milling and fine grinding. The cold processing process of optical lenses requires high-precision tooling so that the optical lenses can achieve the required precision. [0004] The cold processing process of optical lenses has the following steps: [0005] Th...

AI Technical Summary

Problems solved by technology

[0014] Processes such as milling, fine grinding, and polishing require machining discs and other tooling. In order to avoid the vibration and wear of the processing discs on the lenses during processing, elastic discs made of elastic materials have been used at present. However, in the process of processing optical lenses, Due to the elastic shaking of the elastic plate, the positioning of the optical lens is poor, it is easy to be damaged by processing, and the scrap rate is high

Therefore, the traditional elastic disk is prone to unstable product quality and high lens scrap rate during the processing process, which cannot meet the technical requirements of users.

At the same time, the installation between the original optical lens and the processing disc is not in place, and it is easy to shake or even fall off
