The mechanism can clamp and fix the coating object during processing, avoid the object from shifting during rotation, protect the field mirror, and ensure accurate transmission of the laser beam by setting clamping devices and protective devices.
[0004] For example, the invention patent CN116160137B proposes a multi-station rotary disc type laser etching device.
