AI Technical Summary

Technical Problem

During the polishing process of optical lenses, the poor adhesion between the freeform lens and the polishing skin leads to uneven polishing, requiring multiple adjustments, which affects efficiency and may cause uneven wear.

Method used

By employing a flexible pressing method, the combination of the airbag layer and the polishing head ensures that the polishing cloth is completely adhered to the lens surface. The gap is monitored in real time by the detection unit, and the pressure of the airbag is automatically adjusted to maintain close contact and avoid uneven wear.

Benefits of technology

It improves polishing efficiency, ensures the quality of lens surface polishing, reduces the number of manual adjustments, and allows for timely detection and correction of uneven wear issues.
