2. The straightening mechanism clamps the inner side and the outer side of the root of the pin and moves back to the ceramic head to straighten the iron pin by inserting the rod body in the root gap between the roots of the pin and matching with the first straightening clamp, so as to correct the deformed iron pin and improve the success rate of perforation, the success rate of perforation of the second straightening clamp is generally not 80 percent, the success rate of perforation of the second straightening clamp is 98 percent, and the success rate mainly depends on the quality of a bulk capacitor and the deformation degree of the iron pin in the transportation process.

3. The lug shaping mechanism shapes and corrects the lug tightly attached to the stator through the lower shaping strip which can be inserted between the lug and the outer wall of the stator, so that the relative position of a threading hole is stable, the deformation of almost the lug of the bulk micro motor stator is deformed towards one side of the stator in practice, the design gap between the lug and the stator is possibly small, and the lug is pressed towards the stator easily when the micro motor is contacted with the micro motor.

In order to ensure that the ear with too large upwarp can be corrected, an upper shaping strip is also arranged in the application.

The gear sleeving mechanism feeds the gear into the gear through hole of the rotating disc through the gear vibrating disc, the gear sleeving mechanism pushes the gear into the micro motor rotating shaft along with the rotation of the rotating disc to a corresponding position, or the micro motor is controlled to be inserted into the gear through the gear vibrating disc, so that the assembly of the bulk gear and the micro motor rotating shaft is realized.

The above description is only a preferred embodiment of the present invention, and the present invention is not limited to the above description, and although the present invention has been disclosed with the preferred embodiment, it is not limited to the present invention, and any skilled person can make modifications or changes equivalent to the above embodiments without departing from the scope of the present invention, but all the modifications, equivalent changes and modifications made by the technical spirit of the present invention to the above embodiments are within the scope of the present invention.
