Abstract
The invention discloses a laser-dry ice mixed cleaning method which comprises the following steps: placing a to-be-cleaned workpiece with an adhesive layer on the surface on a platform, regulating and starting a laser device and a dry ice jet cleaning device, and dry ice particles sprayed by the dry ice spray head and laser beam spots emitted by the laser head move synchronously and act on the same area of the adhesion layer at the same time all the time, the adhesion layer is removed along the preset cleaning path through the synergistic effect of the dry ice particles and laser, and therefore efficient and high-quality surface cleaning is completed. The problems that in an existing cleaning technology, the cleaning efficiency is poor, the cleaning quality is low, and the process adaptability is poor are solved.
