IMD production process for manufacturing PC polarized lens

Abstract

The invention relates to an IMD production process for manufacturing a PC polarized lens, and belongs to the technical field of PC polarized lens production and manufacturing. The process comprises the following steps: 1, tearing a film of a polarized arc-shaped sheet; 2, blowing the polarized arc-shaped sheet to remove dust; 3, putting the polarized arc-shaped piece into a lens bearing sub-mold, and conveying the lens bearing sub-mold into an injection molding machine; 4, starting the injection molding machine, and conducting injection molding on the polarized arc-shaped piece in the lens forming sub-mold; 5, after injection molding, moving the lens bearing sub-mold with the polarized lens out of the injection molding machine; and 6, taking out the polarized lens from the lens bearing sub-mold, and packaging the polarized lens. In order to improve the production efficiency in the production process of a PC polarized lens product, the invention provides the IMD production process for manufacturing the PC polarized lens, on one hand, the efficiency in the production process can be effectively improved, and on the other hand, the quality of the product can be improved.

Description

technical field [0001] This application relates to the field of manufacturing PC polarized lenses, in particular to an IMD production process for PC polarized lenses. Background technique [0002] PC polarized lenses are also called outer space polarized lenses. The scientific name of PC material is polycarbonate. It is widely used in aerospace and military fields. Its strength is 60 times that of glass lenses, 20 times that of TAC lenses, and 10 times that of resin lenses. Known as the safest material in the world. [0003] PC polarized lenses can be said to be a revolutionary upgrade to traditional polarized lenses. It overcomes the problem of spherical astigmatism caused by the easy deformation of traditional TAC polarized lenses after being framed; it also solves the problem of relatively heavy and fragile glass polarization; at the same time, PC polarized lenses The use of polymer materials has strong impact resistance; in addition, most of the PC polarized lenses use ...

Problems solved by technology

[0005] Since the manufactured sunglasses are often adapted to the curvature of the human face, the shape of the polarizer often has a certain curvature, so that the polarizer often needs to be manually inserted into the lens during the melt injection molding process. In the mold, and put the mold into the injection molding machine by manual operation for injection molding, this process is a test of the speed of the staff, and a little carelessness will often cause the shutdown of the production line, which greatly increases the difficulty of producing polarized lenses.
