The welding mechanism 3 includes a mounting frame, which is fixed on the machine body 1 and located on the rear side of the stator clamping mechanism 2, and also includes a welding head, which can be moved horizontally and vertically by a conventional driving structure, such as a screw lifting structure or a hydraulic cylinder structure.

[0050] Cleaning Agency

[0051] This embodiment further includes a cleaning mechanism 5, which is disposed on the machine body 1 and located in front of the stator clamping mechanism 2. The cleaning mechanism 5 includes a cleaning roller 50 for cleaning the surface of the stator. The cleaning mechanism 5 can move in the horizontal direction.

[0052] The cleaning mechanism 5 further includes: a roller frame 51, which is movably arranged on the machine body 1; a rotating motor 52, which is arranged on the roller frame 51; an exhaust fan 53, which is arranged on the side of the roller frame 51, and the air inlet end of the exhaust fan 53 is connected to a dust suction pipe 54; a filter 55, which is arranged at the air outlet end of the exhaust fan 53;

[0053] The roller frame 51 can move in the horizontal direction, the cleaning roller is rotatably arranged on the roller frame 51, the rotating motor 52 can drive the cleaning roller to rotate, and the dust suction pipe 54 is located at one side of the cleaning roller.

[0055] The top end of the filter core 9 is provided with an air hole 10 connected with the air outlet 72, and the air inlet 70 at the bottom end of the filter tube 7 is conical.

[0056] A guide groove cooperating with the roller frame 51 is provided on the surface of the machine body 1. The roller frame 51 can move horizontally along the surface of the machine body 1 by installing a guide block at the bottom to cooperate with the guide groove. The roller frame 51 can be driven to move by a conventional driving cylinder. Bristles are evenly distributed on the surface of the cleaning roller.

[0064] The cleaning mechanism 5 is reset, and then the preheating mechanism 4 moves downward. After the thermal insulation cover completely covers the motor stator, the gas is transported to each branch pipe 44, and the nozzle 45 discharges gas and ignites it. The motor stator is preheated by the flame.
