Abstract

The present invention discloses an automatic adhesive dispensing process for lens waterproofing, and belongs to the technical field of lens assemblies. The process includes an adhesive dispensing device and an adhesive dispensing method. The adhesive dispensing device includes an adhesive dispensing jig for placing a lens therein and an adhesive dispensing gland disposed above the adhesive dispensing jig. The adhesive dispensing jig is cylindrical. A size of the inner wall of the adhesive dispensing jig matches a size of the lens. 3 notches are formed at the upper end of the adhesive dispensing jig. The adhesive dispensing jig is annular. 3 convex angles are formed on the adhesive dispensing gland. The adhesive dispensing device matches the adhesive dispensing method of the present invention; and with special glue, operation and detection are convenient and fast, the processed product has a stable structure property, and the working efficiency and the product qualified rate are greatlyimproved.

Description

technical field [0001] The invention relates to the technical field of lens assembly, in particular to a lens waterproof automatic dispensing process. Background technique [0002] When assembling the lens, the optical element is generally put into the lens barrel first, and the optical element is pre-fixed in the lens barrel by using the interference between the optical element and the inner wall of the lens barrel, and then glue is dispensed between the optical element and the inner wall of the lens barrel Fix the optical element in the lens barrel. For example, glue is applied between the last assembled lens or the spacer ring and the lens barrel, and then the glue is cured so that the inner lens does not shift or fall out, ensuring the quality of optical performance. At present, there are manual dispensing and automatic dispensing machines. However, no matter whether it is manual dispensing or automatic dispensing machine dispensing, if the needle is not careful or does...
