Abstract

The invention discloses a waterproof automatic glue dispensing process for lenses, which belongs to the technical field of lens assembly technology and includes a glue dispensing device and a glue dispensing method. The dispensing gland above the dispensing fixture, the dispensing fixture is cylindrical, the size of the inner wall of the dispensing fixture matches the size of the lens, and the upper end of the dispensing fixture is set 3 There are two gaps, the dispensing gland is ring-shaped, and 3 convex corners are set on the dispensing gland. The glue dispensing device of the present invention cooperates with the glue dispensing method and is combined with special glue, so that the operation and detection are convenient and fast, the structure and performance of the processed product are stable, and the work efficiency and product qualified rate are greatly improved.

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...
