The anti-rotation mechanism 505 is arranged on the side of the feeding mechanism 504 close to the sleeve interface assembly 4;

[0029] The conveyor belt assembly 1 is used to convey the motor forward;

[0030] The rotation correction assembly 2 is used to correct the position of the keyway of the motor shaft;

[0031] The chain excitation assembly 3 is used to press the flat key into the keyway of the motor shaft;

[0032] The positioning assembly is used to position the motor conveyed on the conveyor belt assembly 1 so that the motor can be positioned at the stations of the rotation correction assembly 2, the chain excitation assembly 3, and the sleeve interface assembly 4;

[0033] The sleeve interface assembly 4 is used to receive the sleeve conveyed by the coupling sleeve assembly 5 and put the sleeve on the motor shaft;

[0034] The coupling sleeve assembly 5 is used to convey the sleeve and align the sleeve;

[0035] In specific implementation, the horizontal conveying mechanism 502 drives the alignment mechanism 503 to reciprocate in the direction of the motor movement. The alignment mechanism 503 transports the sleeve. First, the anti-rotation mechanism 505 rotates the position of the sleeve to a position consistent with the keyway of the motor shaft, and then the feeding mechanism 504 sends the sleeve to the alignment mechanism 503 and conveys it to the sleeve interface assembly 4.

[0036] Furthermore, refer to Figure 5, the fixing mechanism 501 includes a strip-shaped fixing base plate 511. At least four fixing screws 512 are provided at the bottom of the fixing base plate 511.

The output end of the differential 526 is connected with a motor 527. The alignment mechanism 503 is fixed on the upper surface of the slider 523;

[0039] During specific implementation, when conveying the bushing, the motor 527 rotates forward and backward. The motor 527 drives the differential 526, so that the differential 526 drives the gear 525 to rotate, and the gear 525 meshes with the toothed belt 522 to perform reciprocating motion, and the slider 523 reciprocates to make the alignment mechanism 503 feed the bushing.

[0040] Further, referring to Figures 6 to 9 , the alignment mechanism 503 includes a rectangular frame 531 fixed on the upper surface of the slider 523. The rectangular frame 531 is arranged in a hollow manner. A through hole is provided on one side surface of the rectangular frame 531 close to the bushing interface assembly 4. An alignment differential 533 is provided on the inner wall of the rectangular frame 531 at the through hole. The input end of the alignment differential 533 is connected with an alignment motor 532. The output end of the alignment differential 533 passes through the through hole and is provided with a rotating die head 534. A rubber head 535 is provided at the outer end of the rotating die head 534. A bushing 536 is sleeved on the rubber head 535. A feeding mechanism 504 is provided at the top of the rectangular frame 531;

[0041] In specific implementation, when aligning the bushing, the bushing 536 is sleeved onto the rubber head 535. The alignment motor 532 drives the alignment differential 533. The alignment differential 533 drives the rotating die head 534, the rubber head 535, and the bushing 536 to rotate. When the protruding part on the bushing 536 is caught by the anti-rotation mechanism 505, at this time, the bushing 536 is aligned.

[0042] Further, referring to Figure 8 , the feeding mechanism 504 includes a feeding cylinder 541 fixed to the top of the rectangular frame 531. The output end of the feeding cylinder 541 is provided with a feeding bottom plate 542. The outer surface of the feeding bottom plate 542 is provided with an anti-rotation mechanism 505. The anti-rotation mechanism 505 includes a feeding frame 551 arranged in a U shape. The opening of the feeding frame 551 faces downward. The bottom of the feeding frame 551 at the end for feeding is trapezoidally arranged. In the middle of the bottom of the feeding frame 551 at the end for feeding, there is a feeding groove 5511. The feeding groove 5511 is semicircularly arranged and fits the outer wall of the rubber head 535.

[0043] In specific implementation, when feeding, the output end of the feeding cylinder 541 extends outwards, so that the feeding bottom plate 542 pushes the feeding frame 551 forward, and the feeding groove 5511 pushes the bushing 536 forward to convey the bushing 536 to the bushing interface assembly 4.

[0044] Further, referring to Figure 8 and Figure 11 , the outer surface of the feeding frame 551 is provided with an anti-rotation cylinder 552.

[0045] In specific implementation, when aligning, the output end of the anti-rotation cylinder 552 moves downward, pushing the anti-rotation bottom plate 553 downward, so that the anti-rotation bottom plate 553 pushes the vertical surface of the anti-rotation baffle 554 to catch the protruding part of the bushing 536. At this time, the alignment position of the bushing 536 is consistent with the keyway position of the motor shaft. After alignment, the output end of the anti-rotation cylinder 552 contracts.
