[0100] The feeding slide 13 and the output slide 12 are perpendicular to each other; the piston rod of the feeding cylinder 14 is connected to the feeding slide 13, so that the feeding slide 13 carrying the commutator 82 moves to between the pressing mechanism 5 and the fixing mechanism 2.

[0101] Preferably, the sensing element of the press-mounted Hall sensor 7 surrounds the rotating shaft 81 of the rotor 8 and is used to detect the position of the commutator 82 on the rotating shaft 81 of the rotor 8;

[0102] The sensing element of the output Hall sensor 6 is located above the feeding chute 13 and is used to detect whether there is a commutator 82 on the feeding chute 13 .

[0103] like Figure 4 As shown, a commutator press-fitting method is used to press-fit the commutator 82 onto the rotor 8, comprising the following steps:

[0104] S1: Outputting a clamping signal to the rotor clamping cylinder 22, so that the rotor clamping cylinder 22 pushes the rotor clamping block 23, and after the bayonet 25 is engaged with the slot on the side of the rotor 8, receiving a clamping success signal output by the rotor clamping cylinder 22;

[0105] In this step, the rotor clamping cylinder 22 is a cylinder having a magnetic switch for position control;

[0106] When the magnetic switch detects that the piston rod of the rotor clamping cylinder 22 is extended to a specified length, a clamping success signal will be generated, and at this time, the bayonet 25 will engage with the slot on the side of the rotor 8.

[0107] S2: outputting a pressing signal to the rotor positioning cylinder 31 according to the clamping success signal, so that the rotor positioning cylinder 31 pushes the rotor positioning block 32 to contact the rotating shaft 81 of the rotor 8, and then receiving a pressing completion signal output by the rotor positioning cylinder 31;

[0108] In this step, the rotor positioning cylinder 31 is a cylinder with a magnetic switch for position control. When the magnetic switch detects that the piston rod of the rotor positioning cylinder 31 is extended to a specified length, a top pressure completion signal will be generated, and the rotor positioning block 32 will contact the rotating shaft 81.

[0109] S3: Output a vibration start signal to the vibration plate 11 according to the top pressure completion signal, so that the vibration plate 11 starts and outputs the commutator 82 to the feeding slide 13 through the output slide 12; receive the output execution signal output by the vibration plate 11, and output a detection signal to the output Hall sensor 6 according to the output execution signal;

[0110] S4: receiving a material presence signal outputted by the output Hall sensor 6 according to the output execution signal; outputting a feeding execution signal to the feeding cylinder 14 according to the material presence signal, so that the feeding cylinder 14 moves the feeding slide 13 and the commutator 82 to between the pressing mechanism 5 and the fixing mechanism 2, and receiving a feeding in place signal outputted by the feeding cylinder 14;

[0111] In this step, if the feeding chute 13 has a commutator 82, the output Hall sensor 6 will output a material signal; if the feeding chute 13 does not have a commutator 82, the output Hall sensor 6 will output a no-material signal;

[0112] The feeding cylinder 14 is a cylinder with a magnetic switch for position control. When the magnetic switch detects that the piston rod of the feeding cylinder 14 extends to a specified length, a feeding in place signal will be generated. At this time, the commutator 82 will be located between the pressing mechanism 5 and the fixing mechanism 2 and correspond to the lead screw 51.

[0113] S5: outputting a material-picking signal to the push rod motor 41 according to the material-picking signal, and the push rod motor 41 pushes the press-fitting mechanism 5 to move toward the fixing mechanism 2 according to the material-picking signal, so as to obtain the commutator 82 from the feeding slideway 13, stop after contacting the rotating shaft 81 of the rotor 8, and receive the push-in-place signal output by the push rod motor 41;

At this time, the push rod motor 41 will generate a push-in-place signal through the limit switch.

[0117] S6: Outputting a press-fitting signal to the rotary motor 52 according to the push-in-place signal, the rotary motor 52 is started according to the press-fitting signal and press-fits the commutator 82 onto the rotating shaft 81 through the press-fitting sleeve 54; receiving a press-fitting execution signal output by the rotary motor 52;

[0118] In this step, the rotating motor 52 is started according to the press-fitting signal and moves the moving block 53 and the press-fitting sleeve 54 along the axis of the lead screw 51 toward the commutator 82. The press-fitting sleeve 54 pushes the commutator 82 toward the rotating shaft 81 and allows the rotating shaft 81 to penetrate into the through hole of the commutator 82. At the same time, one end of the rotating shaft 81 facing the press-fitting mechanism 5 is inserted into the press-fitting sleeve 54.

[0120] S7: outputting a sensing signal to the press-fitting Hall sensor 7 according to the press-fitting execution signal, and receiving a press-fitting in place signal output by the press-fitting Hall sensor 7 according to the sensing signal;

[0121] In this step, the press-mounted Hall sensor 7 senses the commutator 82 on the rotating shaft 81 according to the sensing signal;

[0122] If the press-fit Hall sensor 7 does not sense the commutator 82 in its sensing area, a press-fit failure signal is generated;

[0123] If the press-fit Hall sensor 7 senses the commutator 82 within its sensing area, a press-fitting in-place signal is generated.
