Four evenly distributed clamps 4 are fixed on the edge of the rotating disk 31. Four stations are sequentially arranged on the surface of the frame 1, and each station corresponds to the clamp 4, including a loading and unloading station, a solder paste injection station, a welding station and a cooling station. An opening is opened on one side of the frame 1, and the loading and unloading station is arranged near the opening side, which is convenient for manual loading or unloading and improves the loading efficiency. A solder paste filling station is fixed with a solder paste filling station. Device 11, a welding device 5 is fixed on the welding station, and a cooling device 12 is fixed on the cooling station. The rotation of the rotating disk 31 is driven by the driving motor 3 to rotate the four clamps 4 on the rotating disk 31.

At the solder paste injection station, the solder paste is filled on the power terminals. At the welding station, the power terminals are heated to weld the solder paste to the power terminals. Then, the terminals are rotated to the cooling station to cool the ends of the power terminals to accelerate the solidification and fixing of the ends of the power terminals. Finally, the terminals are rotated to the loading and unloading stations again to remove the welded power terminals.
