Embodiment Construction

[0014] A two-stage hardened cemented lens process comprising the steps of:

[0015] 1. Lens lamination: Firstly, wash the lens baskets and put them directly on the assembly line for lamination, then glue the appearance, and cure the two lenses for centering to ensure the accuracy of the cores, and then perform temporary hardening to prevent the centering from being centered. Then wipe away glue spills and surface stains for maximum cleanliness before formally hardening to prevent arching of shiny lines.

[0016] 2. Secondary curing procedure: set the illuminance according to three technical standard sections:

[0017] The first standard section: it is stricter for parts of Yasi , and the outer diameter is more than ; the illumination is set to 1500-2000um / cm 2 ;

[0018] The second standard section: for parts Yas is more strict than , and the outer diameter is ; the hardening time is 1-3 hours; the structural illumination is set at 4800-7500um / cm 2 ;

[0019] The third sta...

Abstract

The invention discloses a two stage technology for hardening and combining lenses. The two stage technology for hardening and combining the lenses includes the following steps: 1) performing lens lamination; 2) performing solidification procedures twice; 3) hardening the lenses; 4) roasting the lenses. According to the two stage technology for hardening and combining the lenses, the lenses obtained by being solidified twice and roasted twice are superior in optical performance, no double image exists in light spots imaged by the lenses, the phenomena of chromatic aberration, spherical aberration, glue failure, core shifting, bubbling and the like are eliminated, image quality is improved, hardening requirements of lens combination are met, and product quality is guaranteed.

Description

technical field [0001] The invention relates to the technical field of lens production, in particular to the two-stage hardening operation of lens bonding engineering. Background technique [0002] During the lens production process, the original one-stage hardened surface of the lens will directly cause the lens to be strained, glued, and easily cause eccentricity and air bubbles. The lens is first temporarily hardened, wiped with glue, and then formally hardened. The advantages of the two-stage hardening process are: one is to eliminate the ghosting of the facula in imaging, which is beneficial to eliminate chromatic aberration and spherical aberration, and improve the image quality; the other is to optimize the optical Design and structural design, so the two-stage hardening process of bonding lenses is extremely important. Contents of the invention [0003] In view of the technological requirements of the above-mentioned two-stage lens hardening operation, the purpose...
