Description

Technical Field

[0001] This utility model relates to the field of optical and camera industry equipment technology, specifically to a fully automatic lens stray light detection machine. Background Technology

[0002] Optical lenses are essential components of machine vision systems, directly affecting image quality and the implementation and effectiveness of algorithms. An optical lens consists of lenses and a frame for mounting them. After the lenses and frames are manufactured separately, they need to be assembled. The final step in the assembly process is adhesive curing. This involves applying adhesive to the lens components, such as the final assembled lens element or spacer ring, and connecting it to the lens barrel. The curing of the adhesive prevents internal lens displacement or dislodgement, ensuring high-quality optical performance.

[0003] After assembly, precision optical lenses require overall inspection of the assembled lens components to determine the sealing performance of the assembled components, screen out defective products, and ensure the yield rate of the assembled components. However, at present, the sealing performance of precision optical lenses is mostly tested manually, which has problems such as low efficiency and high cost. Utility Model Content
