Abstract

The invention discloses a laser machining method and device for cooperative motion of a laser galvanometer and an air blowing device. The method comprises the steps that a moving path of the laser galvanometer is planned; scanning machining is carried out by the laser galvanometer according to a planned moving path; the air blowing device moves cooperatively along with the laser galvanometer; andthe device comprises the laser galvanometer, the air blowing device and a driving device, wherein the laser galvanometer is arranged opposite to a laser source, the air blowing device is arranged below the laser galvanometer, and the driving device is used for moving the air blowing device. According to the method, through the optimized path and the mode of block machining on the path, the problemof matching between the high-speed mobility of the galvanometer and the motion of a motor platform is solved; and meanwhile, idle stroke waiting of the galvanometer redundancy is avoided, and the waiting time of the galvanometer idle stroke is reduced to the minimum, so under the condition that the machining efficiency is guaranteed, the influence of the heat effect on the machining effect in thelaser machining process can be reduced, the problem of shielding of a galvanometer light beam in the moving process of the air blowing device is avoided, and the quality of a laser machining workpiece is improved.

Description

technical field [0001] The invention belongs to the field of laser processing, and more specifically relates to a laser processing method and device in which a laser vibrating mirror and an air blowing device move in concert. Background technique [0002] Laser processing is to use the advantages of laser energy concentration, high precision, fast speed, good controllability and not limited by materials to implement cutting, engraving, welding, drilling and other processing methods on various materials such as metals. Since its emergence in the 1970s, it has been widely used in industrial production and has become an indispensable processing method. [0003] In laser processing, in order to reduce the influence of the thermal effect of the laser on the deformation of the workpiece as much as possible, and to avoid the influence of debris during processing on the processing quality to obtain better processing results and quality, it is necessary to blow protection to the proc...
