Automatic cleaning technology for large-aperture optical mirror surfaces using fan-shaped jet streams
For the current issue of the lack of suitable automatic cleaning equipment for large-aperture mirror surfaces,a fan-shaped jet automatic cleaning technology was proposed.The structure,arrangement,and cleaning force of fan-shaped nozzles were studied.The spray angle was controllable within the range of 25° to 125°.An innovative gas-liquid mixed cleaning approach was proposed,and in combination with automated equipment,an automated cleaning device specifically for large-aperture optical mirrors was designed without damaging the mirror surface during the process.This device is capable of completing the mirror cleaning within 1 min.Post-cleaning surface morphology analysis using a Zeta instrument reveals that the remaining impurity particles are smaller than 10 μm in diameter,without observable defects such as pits or scratches.The automated cleaning device boasts high automation,fast cleaning speed,and a cleaning effect,which meet both manufacturing and coating requirements without damaging the mirror surface.The research provides an approach for automated cleaning of large-aperture optical mirror surfaces.
