Laser welding equipment and laser welding method

Abstract

The invention provides laser welding equipment and a laser welding method. The laser welding equipment comprises a welding equipment body, a welding table, a support, a dynamic focusing galvanometer welding system, a vision detection system, a workpiece positioning mechanism, a welding head adjusting driving mechanism and a control system. Image data of a workpiece are obtained through the vision detection system so that accurate positioning can be conducted on a welding line on the workpiece, the welding head is controlled to rapidly move to the welding line position through the control system, and the dynamic focusing galvanometer welding system transmits laser pulses to conduct rapid and accurate laser scanning welding on the workpiece. Meanwhile, in the laser scanning welding process, the dynamic focusing galvanometer welding system is used for conducting dynamic compensation on the out-of-focus error of the laser pulses emitted by the dynamic focusing galvanometer welding system, accordingly, dynamic focusing of the laser pulses is achieved, the welding efficiency and precision of laser welding can be greatly improved, and the labor cost is reduced.

Description

technical field [0001] The embodiments of the present invention belong to the technical field, and in particular relate to a laser welding device and a laser welding method. Background technique [0002] With the continuous development of science and technology, various industrial products emerge in an endless stream, and laser welding equipment is widely used in instant noodles such as industrial product welding. [0003] However, the existing laser welding equipment needs to rely on manual calibration of the position of the welding head, which has a low degree of automation and low welding precision, and cannot quickly and accurately weld products such as power batteries that require high welding precision, thus seriously reducing the quality of laser welding. The welding efficiency and increased labor costs. Contents of the invention [0004] The embodiment of the present invention provides a laser welding device and a laser welding method, which acquires the image dat...
