Abstract

The invention provides a laser welding device with a fume cleaning function. The laser welding device comprises a laser welding gun, wherein a laser welding head is arranged at the lower end of the laser welding gun, a worktable is arranged below the laser welding head, a groove for accommodating a workpiece is formed in the worktable, and air absorption pipes are arranged on side walls of two sides of the groove. According to the laser welding device with the fume cleaning function, the groove for accommodating the workpiece is formed in the worktable, during use, the workpiece is placed in the groove for welding, so that generated fume is relatively concentrated, the air absorption pipes arranged on the side walls of the groove can absorb the fume generated in the groove as much as possible, and accordingly, the fume generated in a welding process can be reduced effectively. Meanwhile, a spray pipe is arranged on each support rod, so that during welding, the spray pipe sprays water to a weld firstly, generated fume can be reduced to a certain extent, water cooling of a weld assembly can be realized, the weld width and thermal effect width can be reduced effectively, and the welding quality can be improved.

Description

technical field [0001] The invention relates to the field of laser welding, in particular to a laser welding device with the function of purifying smoke and dust. 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. Due to its unique advantages, it has been successfully applied in the precision welding of micro and small parts. At present, laser welding ...
