Problems solved by technology

However, due to the increase of processes in this method, lens grinding is time-consuming and labor-intensive, which becomes a bottleneck process that affects the improvement of production efficiency.
Most of the existing lens grinding adopts multi-equipment single-station grinding, that is, the rough grinding, semi-fine grinding and fine grinding of the lens are processed on different equipment respectively. This method not only needs to frequently move the lens to be ground up and down. And transmission, resulting in a long auxiliary time, which seriously affects the production efficiency, and the lens is easy to be damaged during the transmission process; and because of

Abstract

The invention discloses a multi-station grinding device for optical lenses. The multi-station grinding device comprises a machine seat, a rotating disc, at least two stations and lens fixtures, wherein the lens fixtures are arranged on the stations; a rotating positioning mechanism is arranged at the bottom of the rotating disc through a central shaft; the stations include a grinding station and a workpiece loading-unloading station which are located at the side part of the outer periphery of the rotating disc and are distributed in an even central angle relative to the rotating disc; at least one grinding mechanism is arranged on the periphery close to the rotating disc; the rotating positioning mechanism is a multi-station-switched precise positioning device. Compared with existing multi-station grinding equipment, the multi-station grinding device has the advantages that the structure is simple, the cost is low, and the occupied mounting space is small; the multi-station grinding device is particularly applicable to general large, medium, small-sized optical lens production enterprises; furthermore, the operation is simple and convenient, and requirements on the technological level of operators are low.

Description

technical field [0001] The invention relates to the technical field of optical lens processing, in particular to a multi-station grinding device for optical lenses. Background technique [0002] With the continuous development and popularization of optical equipment and instruments, the use of optical lenses is becoming more and more extensive, and the consumption is also increasing. Therefore, the requirements for the production quality and production efficiency of optical lens processing are also getting higher and higher. The main process with the largest workload and the strongest correlation with its production quality in the production of optical lenses is grinding. In order to ensure the processing quality of the lens, the traditional lens grinding usually has two processes of rough grinding and fine grinding, and then grinding and polishing. The dimensional accuracy and optical performance of the lens produced by this process are poor, which is far from being able to...
