Description

Technical Field

[0001] The utility model belongs to the technical field of optical lens processing and preparation, and in particular relates to an optical lens centering calibration device. Background Art

[0002] Optical lenses are important components that form images by refraction of light. Their application range has expanded from the initial film cameras, microscopes, telescopes, simple medical devices and other products to digital cameras, laptops, mobile phones, security surveillance cameras, vehicle-mounted visual systems, smart homes, and aerial drones, which are closely related to human life. As a result, optical lenses occupy an important position in our daily lives. In the process of processing and manufacturing, existing optical lenses generally use a cylinder to push a mechanical claw to align and correct the position of the lens, but the alignment accuracy is not high, resulting in a decrease in the quality of the optical lens during the processing and manufacturing process, and a decrease in the yield rate. The centering correction of the mechanical claw driven by the cylinder sometimes causes excessive clamping force, which can easily cause slight deformation of the lens or poor appearance, and poor repeated positioning accuracy, resulting in a decrease in the efficiency of the overall processing equipment.
