Example Embodiment
[0044] Example one
[0045] Such as Figure 6 As shown, laser welding is performed on a single network transformer. The device for the solderless laser welding method of the network transformer includes a microcomputer 6 and a positioning device for signal connection, a laser welding device, and a shielding gas device. The positioning device includes a clamp 3. The workbench 5, the clamp 3 is embedded and fixed with the magnetic loop coil wire 2-2 of the network transformer at the lowest position of lifting, and the pin frame 1 of the network transformer is fixedly connected with the workbench 5; The laser welding device adopts a dynamic focusing and scanning method, which includes a dynamic focusing unit composed of a laser 7, a beam expander 8, a dynamic focusing unit 9 and a focusing mirror 10 connected in order by an optical path, an X-axis scanning galvanometer 11, and a Y-axis Scanning galvanometer 12; the protective gas device includes a nozzle 4 and its switching mechanism...
