A kind of processing method of lens sticking film

Abstract

The invention discloses a processing method for lens film pasting. According to the technical scheme, the processing method is characterized by including the following steps that (1) gluing is conducted, specifically, UV glue or thermocuring glue is applied between a base lens and a mother lens; (2) pasting is conducted, specifically, the base lens and the mother lens are press-fitted through a press-fitting mold; (3) the first time of curing is conducted, specifically, in the process that the base lens and the mother lens are continuously press-fitted through the press-fitting mold in the step (2), a UV lamp or thermocuring equipment is used for primarily curing the UV glue or the thermocuring glue, wherein the working time duration of the UV lamp or the thermocuring equipment is 5-30 seconds; and (4) the second time of curing is conducted, specifically, a lens is taken out of the press-fitting mold after the step (3), and then the UV lamp or the thermocuring equipment is used for secondarily curing the UV glue or the thermocuring glue, wherein the working time duration of the UV lamp or the thermocuring equipment is 20-180 seconds. The processing method can effectively improve press-fitting efficiency of lens film pasting, so that the lens manufacturing cost is lowered.

Description

technical field [0001] The invention relates to the technical field of spectacle lens processing, more specifically, it relates to a processing method of a lens film. Background technique [0002] In addition to the basic configuration of the traditional spectacle lens, such as plain mirror, convex lens or concave lens, in order to add other optical effects, a layer of film that can produce a predetermined optical effect will be attached or coated on the lens, and the additional film The layer can be a polarizing film, a color filter film or a mirror protection film, etc. For example, when a polarizing film is attached to the surface of the lens, it can become a polarizing lens. [0003] At present, the Chinese patent with the notification number CN106483588B discloses a lens film processing method, which includes the following steps: Step 1: use a shaping process to process the curved surface of the substrate; Step 2: use a cleaning process to make the A microstructure is ...

Problems solved by technology

Although this method can achieve the advantages of no air bubbles, no wrinkles, good bonding effect and excellent optical properties between the bonding surface between the master sheet and the substrate, it is necessary to cure the laminated lens during the film attachment step of the lens. , the curing treatment can use UV light for light curing treatment. Usually, in order to improve the curing firmness of the adhesive, it is necessary to irradiate with UV light for 40-80 seconds, resulting in low efficiency of the lamination operation of the lens film and increasing the manufacturing cost, which is not conducive to widely used
