Abstract

The invention relates to a curve thin board and a laser welding method and laser welding system thereof. The laser welding method of the curve thin board comprises the steps of scanning the curve thinboard, and obtaining curve point cloud data of the curve thin board; treating the point cloud data, and obtaining multiple coordinate data of the curve welding path; fitting the multiple coordinate data, and obtaining the curve welding path curve; controlling a laser welding head to weld the curve thin board along the welding path curve. According to the curve thin board and the laser welding method and laser welding system thereof, the distance between the laser welding head and the curve thin board can be adjusted, the laser welding head adapts to the welding line of the curve thin board, the welding precision of the welding line of the curve thin board is higher, and the problem that the welding precision of the curve thin board is poor is solved.

Description

technical field [0001] The invention relates to the technical field of laser processing, in particular to a curved thin plate, a laser welding method thereof, and a laser welding system. Background technique [0002] Laser welding is an efficient and precise welding method that uses a high-energy-density laser beam as a heat source. Laser welding is one of the important aspects of the application of laser material processing technology. In the 1970s, it was mainly used for welding thin-walled materials and low-speed welding. The welding process is heat conduction, that is, the laser radiation heats the surface of the workpiece, and the surface heat diffuses to the inside through heat conduction. By controlling the width, energy, peak power and repetition frequency of the laser pulse and other parameters to melt the workpiece and form a specific molten pool. Laser welding is used in various industries, such as the manufacture of mobile phone cases in the mobile phone field....
