[0117] like Figure 9 and Figure 10 Shown is the third embodiment of the light curing device 40B of the present invention. In the third embodiment, the light curing device 40B has an isolation box 41B and a conveyor belt device 47B. The two sides of the isolation box 41B respectively have an inlet 42B and an outlet 43B, and the conveyor belt device 47B is arranged under the isolation box 41B, and penetrates into the interior of the isolation box 41B from the inlet 42B of the isolation box 41B. , and pass through the outlet 43B to the outside of the isolation box 41B.

[0118]A plurality of lenses 20 can be placed on the conveyor belt device 47B, so the plurality of lenses 20 can be transported through the inner side of the isolation box 41B through the conveyor belt device 47B. The inner side of the isolation box 41B is also provided with a plurality of ultraviolet light emitting devices 44B. When a plurality of lenses 20 pass through the isolation box 41B, the lenses 20 ca...

Abstract

The invention discloses a method for manufacturing anti-fogging films of lenses and a light hardening device for the anti-fogging films of the lenses. The method for manufacturing the anti-fogging films of the lenses comprises the steps of loading the lenses, specifically, installing the multiple lenses on a movable carrier; spraying the lenses, specifically, spraying light-hardening anti-fogging coatings on the surfaces to be sprayed of the multiple lenses by a spraying device; sucking and removing the redundant coatings, specifically, sucking and removing the redundant light-hardening anti-fogging coatings by a suction nozzle; pre-drying the lenses, specifically, placing the sprayed lenses at the room temperature so as to enable the photo-hardening anti-fogging coatings to be preliminarily dried; hardening the films, specifically, irradiating the multiple lenses with ultraviolet light so as to enable the light-hardening anti-fogging coatings to be hardened to form the anti-fogging films after the light-hardening anti-fogging coatings absorb the ultraviolet light; and taking out the lenses, specifically, taking out the lenses with the hardened films from the light hardening device. The invention provides the light hardening device for the anti-fogging films of the lenses at the same time.

Description

technical field [0001] The invention relates to a method for manufacturing an anti-fog film for a lens and a photohardening device for an anti-fog film for a lens, in particular to a method for manufacturing an anti-fog film for a lens and a lens suitable for lenses made of plastic materials such as swimming goggles or sports glasses Photohardening device for anti-fog films. Background technique [0002] Because, when general optical lenses encounter different environments with large temperature differences outside, fog will often adhere to the surface and affect the user's field of vision. It occurs more often on the type of optical lenses, so the lenses of general swimming goggles or sports glasses are usually treated with anti-fog. [0003] The most commonly used method for the existing optical lens anti-fog treatment method is to spray a thermally hardened anti-fog coating on the lens, and then form an anti-fog film on the lens after the anti-fog coating is heated and d...
