Description

[0002] The gluing process of optical lenses refers to the process of gluing two or more lenses or plane mirrors with optical surfaces that match each other into optical components according to certain technical requirements using optical glue or optical glue. There are two methods for gluing optical lenses, namely gluing and optical glue. The gluing method uses optical grade transparent glue to glue several optical lenses into complex optical components, while the optical glue method relies on the molecular attraction between the polished surfaces of the parts to combine several lenses into a complex optical lens group. After the optical lenses are glued, sometimes there will be glue residue on the surface of the optical lenses, which affects the quality of the optical lenses. Therefore, it is necessary to use a detection device to check the glued optical lenses. Lens inspection; In the prior art, the surface inspection of the optical lens after gluing is mostly performed manually. The personnel pick up the optical lens and use a magnifying glass to observe the gluing position of the optical lens to determine whether there is any glue remaining on the surface of the optical lens. However, this method takes a long time to work, consumes a lot of labor, and has low inspection efficiency. Even if some inspection devices can capture image information of the surface of the optical lens through a camera and then automatically detect whether there is any glue remaining on the surface of the optical lens through software calculation, although it saves human resource investment, it is inconvenient to change the inspection position of the optical lens during the inspection process, which takes a lot of time and affects the inspection efficiency.
