AI Technical Summary

Technical Problem

In existing optical lens polishing equipment, the rigid contact between the lens and the inner wall of the limiting frame leads to wear, uneven polishing, unstable rotation, and uneven distribution of polishing fluid, which affects the polishing accuracy and quality of the lens.

Method used

A limiting fixture is used instead of a limiting frame. Multiple circumferentially distributed lens chucks are used for flexible clamping and positioning. Combined with the design of a spray ring and a base ring, the lens can achieve stable rotation and uniform liquid distribution, avoiding wear on the lens sidewalls and uneven distribution of polishing liquid.

Benefits of technology

It improves the adhesion between the lens and the polishing pad and the uniformity of the polishing fluid, ensuring the precision and quality of lens polishing and solving the problems of unstable lens rotation and uneven polishing.

Abstract

This invention relates to the field of optical lens polishing technology, specifically proposing an automatic optical lens polishing machine. It includes a polishing table and multiple limiting clamps. A turntable is mounted on the polishing table, and a polishing pad is fixed to the upper surface of the turntable. Multiple limiting clamps are fixed on the polishing table and located above the polishing pad. Each limiting clamp includes a horizontally arranged circular tray, with a spray ring rotatably mounted coaxially on the inner wall of the circular tray. A base ring is coaxially fixed on the spray ring. Multiple lens chucks distributed circumferentially are detachably mounted on the base ring, and an adjustment component is also mounted on the base ring for synchronously adjusting the clamping force of the multiple lens chucks on the lens. The automatic optical lens polishing machine provided by this invention achieves stable polishing of the lens by using non-eccentric flexible clamping, adjustable micro-pressure, active rotation, and uniform liquid distribution, ensuring the precision and quality of lens polishing.
