However, for the same light source, the greater the working distance of the light source, the smaller the light-emitting surface of the light source, the brightness of the light source will also be weakened, and the effect and the actual situation cannot be obtained at the same time;

[0037] Working principle: during inspection, the lens is placed above the lens holder 3031, and then the hydraulic component 304 is used to control the lens holder 3031 to descend so as to perform preliminary limiting operations on the lens. The inner side of the lens holder 3031 adopts a soft rubber structure, which can effectively avoid damage to the lens structure while fixing the lens. The lens is moved to the bottom of the positioning component 5 through the detection axis platform 1, and the positioning component 5 is used to detect and position the optical lens above the detection axis platform 1 to prevent the optical lens from offset during inspection.

Adjusting the displacement distance during the detection process can adjust the illumination angle, thereby achieving a more comprehensive detection operation.
