AI Technical Summary

Technical Problem

Existing technologies make it difficult to precisely control the operating force during the film-splitting process, which can easily cause irreversible damage to the precision mask, resulting in a high risk of scrapping.

Method used

A film-prying device for optical films on photomasks was designed, including a fixed base, a photomask fixing assembly, and an optical film prying assembly. The device utilizes a lateral movement structure and a lifting structure to achieve mechanized film prying. Combined with the interference fit between the pin and the process hole of the film frame, it ensures clamping stability and uniform force.

Benefits of technology

This technology mechanizes the film-skimming process, avoiding the problem of inaccurate force during manual operation, reducing the risk of damage to the mask, and improving the reliability and efficiency of film skimming.
