Description

TECHNICAL FIELD

[0001] The utility model belongs to optical lens detection technical field, concretely relates to an optical lens corner testing fixture. BACKGROUND

[0002] In the production process of optical lens, ensuring the accuracy of lens corner is the key step to ensure product quality. The traditional optical lens corner detection usually relies on manual operation, that is, manually rotating the lens on the optical lens support seat, and then detecting the optical lens edge detector. This manual operation has certain limitations in production efficiency, detection accuracy and consistency.

[0003] The traditional manual detection method needs time for lens placement, rotation and alignment, which takes a long time and leads to low production efficiency. Manual operation cannot guarantee the accuracy of rotating the lens each time, which may cause errors in the detection results and affect product quality. Due to the difference in skill level and operation habit of the operator, the consistency of the detection process is poor, and it is difficult to ensure that each lens can be detected with the same standard. Long-time manual operation not only has low efficiency, but also requires high physical and attention of the operator, which is easy to cause fatigue and misoperation.

[0004] In view of this, we propose an optical lens corner testing fixture for optical lens detection by automatic feeding, fixing and rotating the lens to solve the above problems. CONTENT OF THE UTILITY MODEL
