Aluminum alloy anode oxide film and surface paint film compound layer laser cleaning device and method

Abstract

The invention discloses an aluminum alloy anode oxide film and surface paint film compound layer laser cleaning device and method. The device comprises a laser cleaning device, a smoke purifier and adeflectable cleaning platform; the cleaning platform is used for clamping and positioning aluminum alloy workpieces to be cleaned; the laser cleaning device comprises a laser cleaner main machine anda manipulator; the laser cleaner main machine comprises a laser emitter and a laser cleaning head; the laser cleaning head is fixed at the tail end of an arm of the manipulator; the cleaning platformis positioned in a light outlet direction of the laser cleaning head; a scanning galvanometer is arranged in the laser cleaning head; a smoke sucking pipe of the smoke purifier is fixed on the laser cleaning head; laser generated by the laser emitter is radiated to the surfaces of areas to be cleaned of the aluminum alloy workpieces on the cleaning platform after being acted by the scanning galvanometer in the laser cleaning head, so that the areas to be cleaned of the workpieces are dynamically scanned in a selected range; and such particle pollutants as dust generated in the cleaning processof the smoke purifier are treated through the smoke purifier to prevent the personal or environmental pollution.

Description

technical field [0001] The invention relates to the technical field of laser cleaning of aluminum alloy anodic oxide film, in particular to a laser cleaning device and method for an aluminum alloy anodic oxide film and a composite layer of surface paint film. Background technique [0002] Anti-rust aluminum alloy parts generally need to be anodized after manufacture to form an anodized film and then coated with special paint to improve the corrosion resistance of the parts. [0003] After a certain period of use of anti-rust aluminum alloy parts, the original paint layer on the surface will be damaged to varying degrees, which affects the overall corrosion resistance of the parts. It is necessary to remove the original paint layer as a whole before repainting and renovation. [0004] Anti-rust aluminum alloy parts have non-destructive damage during the service life, such as cracks and other defects, the defect area needs to be cleaned up and then welded and repaired, but the...

AI Technical Summary

Problems solved by technology

[0004] Anti-rust aluminum alloy parts have non-destructive damage during the service life, such as cracks and other defects, the defect area needs to be cleaned up and then welded and repaired, but the anodic oxide film will affect the welding quality, resulting in different degrees of defects such as pores and inclusions , so it is necessary to remove all the original paint layer and anodized film layer in the defect area before repairing welding
