[0003] The conventional structure of the hollow cup motor rotor includes a winding coil, a rotor shaft and a commutator. The commutator is mounted on the rotor shaft, the winding coil is sleeved on the outer periphery of the commutator, and three circumferentially distributed pins on the winding coil are welded to three circumferentially distributed commutator segments of the commutator.

[0004] In the prior art, manual work is usually used when welding hollow cup rotors. The assembled hollow cup motor rotor is placed on the operating table. That is, the winding coil is first manually assembled to the outer periphery of the commutator and the pins of the winding coil are aligned with the commutator segments of the commutator.

[0032] The present invention will be further described below in conjunction with the accompanying drawings.

[0033] like Figure 1-Figure 14 As shown, a finishing device for hollow cup motor winding coils includes a base 10, a multi-station rotating disk 20 arranged on the base 10, and a loading station 30, an alignment station 40, a shaping station 50, a cutting station 60 and a transfer station 70 distributed along the circumference of the multi-station rotating disk 20. A driving mechanism 11 for driving the multi-station rotating disk 20 to rotate is provided on the base 10. The driving mechanism 11 can drive the multi-station rotating disk 20 to rotate intermittently, and the driving mechanism 11 is preferably a dividing disk device.

[0034] The multi-station rotating disk 20 is provided with a plurality of groups of circumferentially distributed support seats 21, and the number of the support seats 21 is not less than the number of the stations. The support seats 21 are provided with positioning columns 22 and a clamping mechanism 23 for positioning the winding coil on the positioning columns 22. The positioning columns 22 are arranged vertically upward. Further, the clamping mechanism 23 includes a clamping block 231, a guide column 232 and a connecting block 233. One end of the guide column 232 is connected to the clamping block 231, and the other end of the guide column 232 is connected to the connecting block 233. The support seat 21 is provided with a sliding groove that slides with the guide column 232. An elastic member 234 is abutted between the connecting block 233 and the support seat 21. Specifically, the elastic member 234 is sleeved on the outer periphery of the guide column 232 to play a guiding role. The connecting block 233 drives the clamping block 231 to move toward the side of the positioning column 22 under the elastic force of the elastic member 234, so that the clamping block 231 and the positioning column 22 cooperate to clamp the winding coil. That is to say, under normal circumstances, the clamping block 231 maintains a tendency to clamp in the direction of the positioning column 22.

[0035] The loading station 30 is provided with a loading tray 31 and a first transfer device 32 for transporting the winding coils on the loading tray 31 to the support seat 21. A plurality of limit columns arranged in an array are arranged on the loading tray 31, and the limit columns are used to vertically store the winding coils. The base 10 is provided with a first transfer module 311 for driving the loading tray 31 to move forward and backward. The first transfer device 32 includes a first beam 321, a first fixed block 322, a first clamping jaw assembly 323, a first lifting cylinder 324 and a second transfer module 325. The second transfer module 325 is installed on the first beam 321 to drive the first fixed block 322 to move horizontally. The first lifting cylinder 324 is fixedly installed on the first fixed block 322. The first clamping jaw assembly 323 is fixedly installed at the output end of the first lifting cylinder 324. The first clamping jaw assembly 323 is a first clamping jaw cylinder and a first clamping jaw arranged at the output end of the first clamping jaw cylinder.

[0036] The alignment station 40 is provided with a detection device 41 for detecting whether the pin of the winding coil is in the set position, a pushing device 42 for releasing the positioning of the winding coil by the clamping mechanism 23, and a position adjustment device 43 for driving the winding coil to rotate along the positioning column 22. The detection device 41 includes a connecting frame 411 and an infrared detector 412 installed on the connecting frame 411. The infrared detector 412 detects whether one of the pins of the winding coil is in the set position. When the detection device 41 detects that the pin of the winding coil is in the set position, the pin of the winding coil is just in the required position and does not need to be adjusted by the position adjustment device 43. When the detection device 41 detects that the pin of the winding coil is not in the set position, the pushing device 42 first moves to push the connecting block 233 toward the side of the compression elastic member 234 to release the positioning of the winding coil by the clamping mechanism 23, and then drives the winding coil to rotate by the position adjustment device 43 to adjust the pin position of the winding coil.

[0037] In some embodiments, the position adjustment device 43 includes a mounting plate 431, an adjusting wheel 432, a driving wheel 433, a transmission belt 434 and a servo motor 435. Two adjusting wheels 432 are provided and are arranged horizontally flush. The transmission belt 434 is wound around the outer circumference of the driving wheel 433 and the two adjusting wheels 432. The transmission belt 434 is used to drive the winding coil to rotate. The driving wheel 433 is fixedly connected to the output end of the servo motor 435. The transmission belt 434 wound between the two adjusting wheels 432 is arranged horizontally. The transmission belt is used to drive the winding coil to rotate, thereby adjusting the pin position of the winding coil. In the present invention, a tensioning wheel 436 is symmetrically arranged between the driving wheel 433 and the two adjusting wheels 432.

[0038] Furthermore, the pushing device 42 is a driving cylinder that drives the mounting plate 431 to move forward and backward. The driving cylinder drives the mounting plate 431 to move toward the side of the support seat 21 and pushes the connecting block 233 to move toward the side of the compression elastic member 234, thereby releasing the positioning of the winding coil by the clamping mechanism 23. The mounting plate 431 is provided with an avoidance groove 4311 corresponding to the position between the two adjusting wheels 432. The inner end of the avoidance groove 4311 forms a pushing surface 4312 for compressing the connecting block 233. The mounting plate 431 is provided with a push surface 4312 for compressing the connecting block 233. Two corners are formed according to the positions of the two adjusting wheels 432. When the driving cylinder drives the mounting plate 431 to move toward one side of the multi-station rotating disk 20, the pushing surface 4312 first abuts against the connecting block 233 and pushes the connecting block 233 to move toward one side of the compression elastic member 234. When the mounting plate 431 moves to the set position under the action of the driving cylinder, the clamping block 231 releases the positioning of the winding coil, and then the servo motor 435 drives the driving wheel 433 to rotate to adjust the pin position of the winding coil through the transmission belt 434.

[0039] The shaping station 50 is provided with a pin adjustment device 51 for adjusting the pins of the winding coil to an equal angle setting and a pressing device 52 for pressing down the pins of the winding coil. Furthermore, the pin adjustment device 51 includes a support plate 511, an adjustment block 512, a first cylinder 513 and a lifting mechanism 514 for driving the support plate 511 to rise and fall vertically. The support plate 511 is provided with a through hole corresponding to the positioning column 22 below. The adjustment block 512 is provided with three groups and is distributed at equal angles on the periphery of the through hole. A symmetrically arranged inclined portion 5121 is provided on one side of the adjustment block 512 adjacent to the through hole. The angle between the two inclined portions 5121 of the same adjustment block 512 is equal to or slightly less than 120°. The first cylinder 513 is provided with three groups and corresponds one to one with the adjustment block 512. The first cylinder 513 is used to drive the corresponding adjustment block 512 to extend and retract along the center of the through hole. Specifically, a guide seat 53 is provided on the support plate 511, and the guide seat 53 is provided with a through hole consistent with the through hole on the support plate 511, and the guide seat 53 is provided with a first guide groove with an upper end opening, and the first guide groove corresponds one-to-one with the adjustment block 512, and the adjustment block 512 is partially accommodated in the first guide groove and can move along the guide groove under the action of the first cylinder 513, and the adjacent inclined surface parts 5121 of the adjacent adjustment blocks 512 cooperate to adjust the pin angle of the winding coil, so that the three pins of the winding coil are set at equal angles, so that they can correspond one-to-one with the three commutator segments set at equal angles on the commutator.

[0040] Further, the pressing device 52 includes a pressing plate 521 and a second cylinder 522. The pressing plate 521 is provided with three groups and arranged at equal angles. The position of the pressing plate 521 corresponds to the groove 222 one by one. The second cylinder 522 is used to drive the pressing plate 521 to expand and contract along the center of the through hole. Specifically, the output end of the second cylinder 522 is connected with a connecting strip 523. The pressing plate 521 is arranged on the other side of the connecting strip 523. The guide seat 53 is provided with three second guide grooves corresponding to the connecting strip 523 one by one. The connecting strip 523 is partially accommodated in the second guide groove. The pressing plate 521 can be extended and contracted along the second guide groove under the action of the second cylinder 522. When the pin adjustment device 51 completes the adjustment of the pin, the pressing device 52 starts to work, and the pin of the winding coil is pressed down into the groove 222 of the positioning column 22 through the pressing plate 521.

[0041] The cutting station 60 is provided with a cutting device 61 for cutting the pins of the winding coil. Further, the positioning column 22 is provided with a central channel 221 with an upper opening, and the upper end surface of the positioning column 22 is provided with three grooves 222 arranged at equal angles, and the grooves 222 extend from the outer wall of the positioning column 22 to the central channel 221. Further, the cutting device 61 includes a support frame 617, a mounting block 611 slidably arranged on the support frame 617, a connecting cylinder 612 fixedly arranged on the mounting block 611, a sleeve 613 slidably arranged in the connecting cylinder 612, a spring 614 for driving the sleeve 613 to move upward, a needle body 615 fixedly connected to the mounting block 611, and a downward pressure cylinder 616 for driving the connecting block 233 to cut. The center of the sleeve 613 is provided with an avoidance channel that cooperates with the needle body 615 for guiding, and the outer diameter of the needle body 615 is adapted to the aperture of the central channel 221 of the positioning column 22. When the downward pressure cylinder 616 drives the mounting block 611 to move downward, the lower end of the sleeve 613 first contacts the upper end surface of the positioning column 22, and the needle body 615 begins to extend into the central channel 221 of the positioning column 22 to cut the winding coil pins located in the central channel 221 area.

[0042] The transfer station 70 is provided with a second transfer device 71 for transferring the winding coil on the support seat 21.
