The third material picking mechanism 92 picks up the motor assembly on the material discharging fixture 1060 and rotates it to a preset angle and places it in the material discharging position 9111. In this embodiment, the preset angle is 90°, that is, the motor assembly is rotated from a vertical state to a flat state so as to operate the side of the motor body 1001. After the motor assembly is placed in the material discharging position 9111, the clamping assembly 9112 acts to clamp and position the motor assembly from both sides and expose the side of the motor body 1001 so as to polish the side of the motor body 1001. On the other hand, the positioning assembly 912 includes a bending member 9121, and the bending member 9121 acts to bend the ground wire to the other end at the welding position. The bending member 9121 is L-shaped, and the bending member 9121 can slide back and forth on the frame 101. Since one end of the ground wire is welded to the circuit board 1004 of the motor assembly, the other end protrudes out of the circuit board 1004. When the bending member 9121 slides close to the motor body 1001 on the material discharge position 9111, it contacts the ground wire and drives the ground wire to move horizontally to bend the ground wire, so that one end of the ground wire contacts the polished welding position. The bending member 9121 positions one end of the ground wire on the welding position, and then the fourth welding mechanism 94 welds the other end of the ground wire to the welding position.

The gear loading device 103 loads the gear part 1002 onto the assembly position 211 of the first assembly device 20. The material taking device 10 is used to pick up the motor body 1001 on the motor loading device 102 and place it on the assembly position 211 to cooperate with the gear part 1002, and press-fit it through the pressing assembly mechanism 21. The motor body 1001 assembled with the gear part 1002 is placed on the correction mechanism 22 for correction by the material taking device 10, and then the first material taking mechanism 23 places the motor body 1001 assembled with the gear part 1002 into the material discharging fixture 1060 on the turntable mechanism 106. The second assembly device 30 is used to assemble the end cover 1003 loaded from the end cover loading device 104 onto the motor body 1001. The third assembly device 40 is used to assemble the circuit board 1004 loaded from the circuit board loading device 105 onto the motor body 1001 to form a motor assembly. The first welding device 50 is used to weld the positive wire on the motor assembly. The second welding device 60 is used to weld the negative wire on the motor assembly. The third welding device 80 is used to weld one end of the ground wire on the motor assembly. The fourth welding device 90 is used to weld the other end of the ground wire on the motor assembly. The gear part 1002, the end cover 1003 and the circuit board 1004 can all be automatically loaded and automatically assembled with the motor body 1001 to form a motor assembly. And the positive wire, the negative wire and the ground wire can be automatically welded on the circuit board 1004 of the motor assembly.
