A testing device for testing the flatness of optical lens polishing

Abstract

The invention relates to the technical field of optical lenses, in particular to a testing device for testing the smoothness of optical lens grinding, which includes a casing, the inner surface of the casing is rotatably connected to a limit link, and the limit link is far away from the shell. One end of the body is rotatably connected with a first slider, the first slider slides inside the fixed frame, the lower surface of the fixed frame is fixedly connected with a bearing seat, and the bottom end of the bearing seat is rotatably connected with a worm, so The bottom end of the worm is fixedly connected with a contact rod. When the touch rod slides, the adjustment block exerts a force on the spring support rod, so that the slide frame slides again inside the limit frame. The bottom of the rod is sprayed out, and at the same time, the uneven position of the lens is marked, which is convenient for the staff to find the uneven position on the lens after the inspection is completed, so that the staff can observe the defect position on the lens more intuitively.

Description

technical field [0001] The invention relates to the technical field of optical lenses, in particular to a detection device for testing the smoothness of optical lens polishing. Background technique [0002] Optical glass is mixed with high-purity oxides of silicon, boron, sodium, potassium, zinc, lead, magnesium, calcium, barium, etc. according to a specific formula, melted in a platinum crucible at high temperature, and stirred evenly with ultrasonic waves to remove air bubbles; then after a long time Slowly cool down to avoid internal stress in the glass block, and use processing equipment to process and polish the optical lens into a circular shape as needed. The polished lens needs to be tested by testing equipment to check the flatness of the lens and whether there are defects. [0003] However, the existing detection equipment cannot promptly remind the staff of the result of the lens detection during the detection process, and after the detection, the staff needs to f...
