[0016] The utility model is described in detail below in combination with the drawings and specific embodiments.

[0017] Please refer to Figs. 1 to 3 The utility model provides a kind of quick positioning welding tool for energy storage inverter power device, including: tray 1, be set to the positioning plate 2 on the tray 1, the elevated plate 3 being set to the positioning plate 2 both sides, and the pressing plate 4 being hinged to one side elevated plate 3, the positioning plate 2 is distributed and is provided with several lower guide blocks 21 and positioning needle 22, the positioning plate 2 is movably placed with PCB board, the lower guide block 21 is correspondingly set to the edge outside of PCB board, the positioning needle 22 is corresponding with the positioning hole on PCB board, the bottom surface of the pressing plate 4 is distributed and is provided with several pressing needles 41, the pressing plate 4 is covered on the elevated plate 3 of the other side of positioning plate 2 around hinge position.

[0018] When the power device of the inverter needs to be welded, the PCB is placed on the tray 1, the edge position of the PCB is limited by the guide block 21, and the positioning needle 22 is inserted into the positioning hole on the PCB, so that the PCB is fixed and limited in the X-axis and Y-axis directions, and movement of the PCB is prevented. Then, the pressing plate 4 is flipped and closed around the hinge position, so that the pressing needle 41 is tightly pressed on the PCB, and the PCB is tightly pressed on the positioning plate 2, so that the PCB is fixed and limited in the Z-axis direction. Then, the whole welding tool is moved to the welding position, and the pins of the power device on the PCB are welded. In the utility model, the guide block 21 and the positioning needle 22 on the positioning plate 2 provide limiting and fixing for the PCB, and the pressing needle 41 on the pressing plate 4 tightly fixes the PCB, so that the power device on the PCB of the energy storage inverter is quickly positioned, and the power device and the PCB are conveniently welded and fixed.

[0019] In some embodiments, the welding area of the PCB on the pressing plate 4 is provided with a skylight 42. The welding area of the power device on the PCB is exposed outside through the skylight 42, so that the power device on the PCB fixed and limited by the welding tool is conveniently welded by the welding equipment.

[0020] In some embodiments, the pressing needle 41 includes an upper limiting pressing needle 411, an upper positioning pressing needle 412 and a power device pressing needle 413. The power device pressing needle 413 is arranged at a corresponding position of the power device on the PCB. The upper limiting pressing needle 411 is arranged outside the edge of the PCB. The upper positioning pressing needle 412 is arranged at a position corresponding to the positioning hole on the PCB, and the positioning needle 22 on the positioning plate 2 is provided with a insertion hole. The positioning needle 22 passes through the positioning hole on the PCB and is inserted into the insertion hole of the upper positioning pressing needle 412.
