Abstract
Description
Technical Field
[0001] The utility model relates to a lens optical detection device, belonging to the technical field of optical detection. Background Art
[0002] The detection of telescope lenses involves multiple aspects to ensure the optical performance, mechanical stability, alignment, and efficient operation of the electronic and control systems of the telescope. There are currently two mainstream lens detection methods. One is manual detection, which requires workers to manually adjust the angle and orientation of the lens under a strong light to detect the lens. This detection method has low detection efficiency and a high missed detection rate, and is increasingly unable to meet the production requirements. The other is automated detection, which uses a camera to take pictures of the lenses on the production line and then transmits the taken lens images to a computer for processing. The quality of the lens images will directly affect the computer's judgment of the lens quality. However, since automated detection is a still-developing technology, the quality of the lens images collected by mainstream automated detection equipment is very poor. Therefore, in order to improve the detection accuracy, how to obtain high-definition lens images has become an urgent problem to be solved in automated detection. When the existing detection device detects telescope lenses, in order to obtain clear pictures, the length of the target used reaches 10.6 meters, resulting in an overly large volume of the entire device, which is not conducive to operation. At the same time, the device uses manual focus adjustment, and it is easy to generate shaking during the adjustment process, affecting the measurement accuracy. Summary of the Utility Model
