An optical glass thickness measurement stage

Abstract

This utility model relates to the technical field of equipment for optical glass testing, and discloses an optical glass thickness testing platform, including a worktable, a support platform, and a top plate. Measuring mechanisms are provided at the bottom of the top plate. Lifting mechanisms are provided on both sides of the top of the support platform, and a motor is provided at the bottom of the placement platform. After the optical lens is fixed, the measuring mechanism is reset, and then the motor is started. The motor rotates the placement platform, allowing the measuring mechanism above it to measure the thickness of the lens at multiple points. In this utility model, the lifting mechanisms on the left and right sides of the support platform, through the rotation of knobs, drive gear one to mesh with gear two, which in turn drives the top shaft to rotate, thereby causing the lifting plate to lift and lower the measuring mechanism. After resetting the measuring mechanism, the placement platform rotates with the assistance of the motor, thus enabling multi-point measurement of the optical lens and improving the accuracy of optical lens measurement.

Description

Technical Field

[0001] This utility model relates to the technical field of equipment for optical glass testing, and in particular to an optical glass thickness testing platform. Background Technology

[0002] As a core material in optical instruments, display devices, semiconductor devices and other fields, the thickness accuracy of optical glass directly determines the optical performance and stability of downstream products. This places stringent requirements on the accuracy, efficiency and adaptability of thickness detection. In order to ensure the quality of glass, relevant personnel often use optical glass thickness detection stages to detect the thickness of optical glass.

[0003] However, in optical glass thickness testing, measuring thickness at a single point, such as the center, cannot reflect thickness deviations in critical areas such as edges and corners. Since uniformity directly determines the optical performance of downstream devices, the inability to accurately measure the thickness of optical lenses is a current challenge.

[0004] Therefore, those skilled in the art have provided an optical glass thickness detection stage to solve the problems mentioned in the background art. Utility Model Content

After the lens is placed, the knob 302 is rotated to reset the measuring mechanism 2. Then, the motor 13 is started. The motor 13 drives the motor shaft 14 to rotate, causing the placement stage 16 to rotate.
