Abstract

The invention discloses a manufacturing method of resin optical lens. The manufacturing method of the resin optical lens comprises the following steps: step 1, designing a secondary mold correspondingto optical lens to be manufactured as needed; step 2, manufacturing the secondary mold through 3D printing technology according to the design in the step 1; step 3, grinding, polishing the secondarymold; step 4, pouring liquid state materials to a mold cavity of the secondary mold; step 5, curing the liquid state materials to obtain a soft mold; step 6, pouring liquid state thermosetting resin into a mold cavity of the soft mold; step 7, curing the liquid state thermosetting resin; step 8, opening the soft mold, obtaining the needed resin optical lens; by adopting the manufacturing method ofthe resin optical lens, the manufacturing period of the resin optical lens is enabled to be short, the manufacturing cost is low, and the performance and quality of the lens can be guaranteed.

Description

technical field

[0001] The invention relates to the manufacture of lenses, in particular to a method for manufacturing resin optical lenses. Background technique

[0002] Resin optical lenses are generally produced by injection molding, that is, the corresponding molds are manufactured first, and then resin materials are poured into the cavity of the molds, and the lenses are obtained after the resin materials are cured. The material of the general resin optical lens manufacturing mold is metal or glass. Due to the high hardness of metal or glass, in the injection molding process, in order to consider the shrinkage and deformation of the resin and the difficulty of mold opening, it is necessary to carry out complicated processing on the male mold and the female mold. Structural design (such as the optical lens mold disclosed in Chinese patent CN201520503336.X), complex structural design will inevitably increase the manufacturing cost and the manufacturing cycle of the mold. ...
