Abstract
Description
Technical Field
[0001] The embodiment of the utility model relates to the technical field of optical detection, in particular to an upper and lower surface detection mechanism for military lenses. Background Art
[0002] Military lenses are optical lenses used on military equipment. During production and processing, some lenses may occasionally have defects due to material and process problems. At this time, they need to be inspected to eliminate defective products. Optical cameras are now mostly used to achieve this.
[0003] In the current inspection process, the inspection camera is usually set directly above the inspection station. When the workpiece is moved to the inspection station, it is inspected by the inspection camera.

This makes it easy for the inspection result to have a certain deviation due to interference from external light sources during actual inspection, affecting the inspection accuracy. For this reason, a military lens upper and lower surface inspection mechanism is specially provided to solve the above problem. Utility Model Content
