Method and die for manufacturing glass polarizing lens

Abstract

The invention discloses a method for manufacturing a glass polarizing light lens, and belongs to the field of lens manufacturing. The method comprises the first step of clamping a polarizing film and heating and humidifying the polarizing film until the polarizing film is softened, the second step of bonding the convex plane of a back glass thin sheet with one face of the polarizing film to enable the curve radian of the polarizing film to be consistent with the radian of the convex plane of the back glass thin sheet and removing dust on the surface of the polarizing film and bubbles between the polarizing film and the back glass thin sheet, the third step of bonding the concave plane of a front glass thin sheet with the other face of the polarizing film and removing the bubbles between the polarizing film and the front glass thin sheet, the fourth step of roasting and solidifying the glass polarizing lens, and the fifth step of cutting the unnecessary polarizing film and carrying out washing and testing. The invention further discloses a die for manufacturing the glass polarizing lens, the forming technology of the glass polarizing light lens is simplified, and the production efficiency and the finished product yield are improved; the special forming die is adopted, and the die is simple in structure, convenient to machine and manufacture and low in cost.

Description

technical field [0001] The invention relates to a manufacturing method and mold of a lens, more specifically, to a manufacturing method and a mold of a glass polarizing lens. Background technique [0002] Polarized lenses are manufactured according to the principle of polarization of light, which can block the scattered reflected light in natural light, glare and irregular reflected light of objects, so as to avoid eye discomfort and safety hazards. Wear it when you are in the sun, or playing in a lake with strong waves, or in a glass building, or driving on a smooth road, to filter the strong light reflection and avoid inconvenience to people's life, travel, especially driving in summer . [0003] The process structure of the existing polarizing lens mainly adopts two methods: (1) The process structure in which the polarizing film is placed on the concave surface of the mold and refilled with resin is integrally formed. The forming structure of this process is relatively s...
