Abstract

The invention discloses laser dry type cleaning equipment for aluminum alloy anodic oxide films. The laser dry type cleaning equipment comprises a cleaning platform and a laser cleaning device, the laser cleaning device comprises a laser cleaning main machine and a light source emitting system arranged on the laser cleaning main machine, and the laser cleaning main machine is of an all-in-one machine frame type; the light source emitting system comprises a control system and a laser emitter, the control system is used for controlling the laser emitter, and a laser device in the laser emitter is a pulse laser; the cleaning platform is located at the bottom of the light emitting surface of the laser cleaning device, and a workbench is used for placing aluminum alloy workpieces to be machined. The cleaning equipment is used for solving the problems existing in the prior art; a laser cleaning head is used for emitting linear light spots to clean the anodic oxide films of the aluminum alloyworkpieces, the cleaning effect is guaranteed, a cleaning solution is not needed, and the cleaning equipment is an environment-friendly cleaning scheme. The invention further provides an aluminum alloy anodic oxide film laser dry type cleaning method high in cleaning efficiency and good in cleaning effect.

Description

technical field [0001] The invention relates to the technical field of laser cleaning of anodic oxide films of aluminum alloys, in particular to a laser dry cleaning equipment and method for anodic oxide films of aluminum alloys. Background technique [0002] Aluminum alloy workpieces are generally anodized to form an anodized film after manufacture, which improves corrosion resistance and facilitates storage. However, when the aluminum alloy workpiece is welded, the existence of the anodic oxide film will cause different degrees of defects such as pores and slag inclusions in the weld, so it is necessary to remove the anodic oxide film on the surface of the workpiece first. The traditional removal method (manual grinding) has the problems of low cleaning efficiency, substrate damage, and serious dust and particle pollution. The cleaning effect is poor, and the waste after cleaning cannot be discharged in time, which will cause pollution to the human body or the environment....

Problems solved by technology

However, in the welding process of aluminum alloy workpieces, the existence of anodic oxide film will cause different degrees of defects such as pores and slag inclusions in the weld, so it is necessary to remove the anodic oxide film on the surface of the workpiece first.

The traditional removal method (manual grinding) has the problems of low cleaning efficiency, substrate damage, and serious dust and particle pollution. The cleaning effect is poor, and the waste after cleaning cannot be discharged in time, which will cause pollution to the human body or the environment.
