[0034] The assembly guide component 5 includes a mounting base 51 installed on the top of the frame 1, a fourth electric push rod 52 is arranged inside the mounting base 51, a movable plate 514 is installed at the telescopic end of the fourth electric push rod 52, a third motor 53 is installed on the top of the movable plate 514, a third electric push rod 55 is installed on the top of the mounting base 51, and the power drive end of the third motor 53 is connected to an elastic positioning column 54; a support frame 56 is installed at the telescopic end of the third electric push rod 55, a telescopic rod 57, a fixed rod 59, a first mounting rod 511 and a second mounting rod 512 are respectively installed at the bottom of the support frame 56, a positioning plate 58 is installed at the bottom end of the telescopic rod 57, a fourth pressure sensor 510 is arranged at the bottom of the fixed rod 59, a positioning card plate 513 is installed at the bottom end of the first mounting rod 511 and the second mounting rod 512, and balls are arranged at the bottom of the two positioning card plates 513.

[0035] The armature is composed of an armature shaft, an armature core, an armature winding, a commutator, etc. Its function is to generate electromagnetic torque. After the armature shaft, the armature core, and the armature winding are assembled, the armature winding is located at the armature core and needs to be assembled with the commutator and welded.

[0036] The whole device is operated by the control device 9; the assembled armature shaft, armature core and armature winding are placed on the top of the moving seat 23, and the commutator is placed on the top of the mounting seat 51; when the first pressure sensor 28 senses the pressure, a signal is sent to the double-headed electric push rod 25, and the telescopic ends of both ends of the double-headed electric push rod 25 drive the clamping plate 27 installed on one side to move toward the middle through the connecting frame 26, until the two clamping plates 27 clamp and fix the armature core, the second electric push rod 21 is started, and the telescopic end of the second electric push rod 21 drives the connecting seat 22 to move forward, and the moving seat 23 is located at the top of the frame 1 through the setting of the slide plate 24 and the slide groove 10. Move linearly until the laser sensor 8 senses that the moving seat 23 has moved to the corresponding position, and the telescopic end of the second electric push rod 21 stops operating;

[0037] After the moving seat 23 moves to the appropriate position, the telescopic end of the first electric push rod 3 drives the guide paint scraping assembly 4 to move downward, so that the guide plate 414 corresponds to the armature winding, and one end of the armature winding is close to the position of the guide plate 414; when the first electric push rod 3 drives the guide plate 414 to correspond to the armature winding, the first motor 44 and the timer 42 are started at the same time, and the timer 42 is set to make the first motor 44 operate for a certain period of time, and the power driving end of the first motor 44 drives the half gear 45 to rotate. When the half gear 45 rotates clockwise and meshes with the first rack 46, the first rack 46 and the second rack 47 are slidably connected to the bottom of the fixed frame 43 through the setting of the connecting groove 417 and the connecting block 418. At this time, the first rack 46 drives the bottom-mounted fixed plate 49 to the electric When the armature winding is close to the second pressure sensor 415, when the armature winding does not correspond to the plurality of guide holes 416, the armature winding will collide with the second pressure sensor 415. When the second pressure sensor 415 senses that the pressure value is changed, the first motor 44 stops operating. At this time, the second motor 410 starts to drive the driving gear 411 to rotate, and the driving gear 411 drives the driven gear 413 to rotate. The driven gear 413 drives the guide plate 414 to rotate through the rotating plate 412. When the armature winding does not apply pressure to the second pressure sensor 415, it means that the armature winding corresponds to different guide holes 416. At this time, the second motor 410 stops rotating, and the first motor 44 starts again. When the half gear 45 is meshed with the first rack 46, the guide plate 414 moves forward toward the armature winding, and the armature winding is located in the plurality of guide holes 416.

[0038] When the armature winding is located in the plurality of guide holes 416, the first motor 44 stops operating again, and the second motor 410 drives the driving gear 411 to rotate in the opposite direction to reset the guide plate 414 and notify the first motor 44 to operate. After the guide plate 414 is reset, the position of the end of the armature winding can be adjusted to facilitate the one-to-one correspondence between the armature winding and the slots of the commutator behind; the first motor 44 continues to operate, and when the half gear 45 is meshed with the second rack 47, the guide plate 414 moves toward the rear end of the armature winding. When the half gear 45 is meshed with the first rack 46 When meshing, the guide plate 414 moves toward the front end of the armature winding, and the guide plate 414 is located outside the armature winding and moves back and forth through the back and forth meshing of the half gear 45 with the first rack 46 and the second rack 47; since the aperture of the guide hole 416 is in an "eight" shape, and the aperture changes from large to small, and a scraper is provided on the inner wall of the guide hole 416, the paint on the outside of the armature winding can be scraped off by the scraper provided in the guide hole 416 when the guide plate 414 moves back and forth, and the provided guide hole 416 plays a guiding role for the armature winding;

[0039] The first motor 44 is started only for a certain time by setting the timer 42. When the timer 42 reaches the set time, the first motor 44 stops rotating, and the telescopic end of the first electric push rod 3 drives the guide paint scraping assembly 4 to move upward. At this time, the paint scraping work on the outer side of the armature winding and the guiding work of the resistor winding can be completed; when the laser sensor 8 detects that the guide paint scraping assembly 4 moves upward, the second electric push rod 21 continues to start and drives the connecting seat 22 to move forward until one side of the moving seat 23 fits with one side of the mounting seat 51, and then the second electric push rod 21 stops operating, so that the armature winding corresponds to the commutator;

[0040] The armature shaft, armature core and armature winding are placed on the top of the moving seat 23, and the commutator is placed on the top of the mounting seat 51. At this time, the moving clamping assembly 2 and the assembly guide assembly 5 are both in operation.

[0041] Embodiment 2

[0042] like Figures 1 to 10 In the second embodiment, other structures remain unchanged. The difference from the first embodiment is that after the commutator is placed on the top of the mounting seat 51 and inserted into the elastic positioning column 54, the telescopic end of the third electric push rod 55 drives the support frame 56 to move downward, and the support frame 56 drives the telescopic rod 57, the fixing rod 59, the first mounting rod 511 and the second mounting rod 512 to move downward at the same time. The telescopic rod 57 drives the positioning plate 58 to clamp and fix the commutator. The ball at the positioning card plate 513 installed at the bottom of the first mounting rod 511 and the second mounting rod 512 is located at the groove of the commutator, and the fourth pressure sensor 510 set at the bottom of the second mounting rod 512 is in contact with the outermost side of the commutator. When the fourth pressure sensor 510 is sensed, it represents that the commutator slots correspond to the armature windings one by one.

[0043] When the balls at the two positioning cards 513 come into contact with the outside of the commutator, the fourth pressure sensor 510 is located at the top of the commutator slot and is in a vacant state without being subjected to pressure. At this time, the slots of the commutator do not correspond one-to-one with the armature windings, and the positioning plate 58 does not contact the commutator. At this time, the power drive end of the third motor 53 drives the commutator arranged outside the elastic positioning column 54 to rotate until the balls of the two positioning cards 513 are located in the slots of the commutator. When the fourth pressure sensor 510 is pressure-induced, the third motor 53 stops operating. At this time, the telescopic end of the fourth electric push rod 52 drives the movable plate 514 to move, and the elastic positioning column 54 is separated from the commutator, so as to facilitate the insertion of the armature shaft into the commutator for connection. When the movable seat 23 fits with the mounting seat 51, the armature windings correspond one-to-one with the slots of the commutator. At this time, the hydraulic cylinder 6 can be started to drive the welding device 7 to perform welding.
