[0029] The NTC is placed on the receiving part 6, and the cutting mechanism 7 cuts the pins of the NTC to a suitable length. The cut waste falls into the waste receiving mechanism 5. The conveying mechanism 2 conveys the semi-finished motor of the fan to be welded to the front of the receiving part 6. The feeding mechanism places the cut NTC to the position where the semi-finished motor is to be welded. Then the feeding mechanism feeds the jig together with the semi-finished motor to the welding mechanism 3. Finally, the welding mechanism 3 welds the NTC to the semi-finished motor. The device automatically cuts the pins of the NTC and welds the NTC, which not only makes the length of the NTC pins consistent after cutting, but also makes it less likely to have defective products during welding, and also improves production efficiency.
