When the shearing structure 4 is in the reset state, the pulling structure can pull the end of the bus bar 51 and can drive the bus bar 51 to move in the direction away from the shearing structure 4, after the bus bar moves to the set distance, the pulling structure stops moving, and the shearing structure 4 acts to shear the bus bar passing through the pulling structure. After the bus bar is sheared, the clamping structure 9 loosens the clamped bus bar, the clamping structure 9 moves towards the reset direction under the driving of the clamping driving structure 10, the shearing structure 4 resets, and the clamping structure 9 resets to clamp the end of the bus bar. The bus bar on the discharging carrying platform is sucked and placed on a welding belt mechanism of the series welding machine under the action of the manipulator. Regarding the soldering flux containing structure 2 and the punching structure 3, when the bus bar passes through the soldering flux containing structure 2, the soldering flux in the soldering flux containing structure 2 is coated on the passing bus bar, and the punching structure 3 is used for punching the bus bar.
