Description

[0002] The commutator is a key component of the drive motor. Its technical performance indicators and quality directly affect the overall performance of the micromotor. The commutator is usually installed on the rotor of the motor and rotates synchronously with the rotor. The function of the micromotor commutator is to change the current direction and magnetic field distribution in the motor winding, so that the motor can run smoothly and normally;

[0029] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0030] Please refer to Figures 1-9, A rotor commutator assembly tool for motor production, including an assembly table 1. A rotating disk 10 is rotatably arranged on the assembly table 1. A fixed ring 21 is fixedly arranged on the assembly table 1. The fixed ring 21 is rotatably connected to the rotating disk 10. A convex rod 22 is fixedly arranged on the rotating disk 10. A first sleeve 23 and a second sleeve 26 are rotatably arranged on the convex rod 22. A first slider 25 and a second slider 271 are slidably arranged on the fixed ring 21. A first rod core 24 is slidably arranged in the first sleeve 23. A second rod core 27 is slidably arranged in the second sleeve 26. The first rod core 24 is rotatably connected to the first slider 25. The second rod core 27 is rotatably connected to the second slider 271. A push rod 32 for press-fitting the commutator onto the rotor core is fixedly arranged on the first slider 25. A detection rod 272 for removing unqualified commutators is fixedly arranged on the second slider 271; a driving mechanism. The driving mechanism includes a driving disk 12 rotatably arranged in the assembly table 1. The driving disk 12 is fixedly connected to the rotating disk 10. A driven disk 15 cooperated with the driving disk 12 is rotatably arranged in the assembly table 1. When the driving disk 12 rotates, while pushing the detection rod 272 through the second rod core 27 to remove unqualified commutators, it presses the qualified commutator onto the rotor core through the first rod core 24 and performs station switching; the convex rod 22 is fixedly arranged along the radial direction of the rotating disk 10 and is close to the outer peripheral surface of the rotating disk 10. Two first springs 28 are fixedly arranged between the first rod core 24 and the inner wall of the first sleeve 23. Two second springs 34 are also fixedly arranged between the second rod core 27 and the inner wall of the second sleeve 26. By setting the first sleeve 23, the first rod core 24, the second sleeve 26 and the second rod core 27 to be telescopic, the volume of the equipment can be reduced. One end of the first rod core 24 far from the convex rod 22 is rotatably connected to the first slider 25. One end of the second rod core 27 far from the convex rod 22 is rotatably connected to the second slider 271. The push rod 32 is arranged on the side of the first slider 25 far from the convex rod 22. The convex rod 22 has a groove 35 for the shaft of the rotor core to extend into. The detection rod 272 is arranged on the side of the second slider 271 far from the convex rod 22. A servo motor (not marked in the figure) is fixedly arranged in the assembly table 1. The output end of the servo motor is fixedly provided with a rotating shaft 11. The rotating shaft 11 is fixedly connected to the rotating disk 10 and the driving disk 12 and is coaxially arranged. The rotating disk 10 is above the driving disk 12. During use, the servo motor drives the rotating shaft 11, the driving disk 12 and the rotating disk 10 to rotate. When the rotating disk 10 rotates, it drives the convex rod 22 to make a circular motion around the axis of the rotating disk 10, so that the parts where the first sleeve 23 and the second sleeve 26 are rotatably connected to the convex rod 22 make a circular motion around the axis of the rotating disk 10, so that the first slider 25 and the second slider 271 make a reciprocating linear motion on the fixed ring 21, such as Figure 4As shown, the rotating disk 10 rotates counterclockwise. When the convex rod 22 rotates to the rightmost side, the push rod 32 retracts into the fixed ring 21, and the first slider 25 is on the side close to the rotating disk 10. At this time, the two first springs 28 in the first sleeve 23 extend, and the slider pushes the detection rod 272 to extend out of the fixed ring 21 and insert into the inner ring of the commutator. The size of the detection rod 272 is adapted to the size of the qualified inner ring of the commutator. When the size of the inner ring of the commutator is too small and the interference fit with the rotor core is too large, the detection rod 272 cannot be inserted into the inner ring of the commutator. When the coaxiality of the inner ring of the commutator is different, the end of the detection rod 272 will abut against the inner ring of the commutator, so that it cannot pass through the inner ring of the commutator normally, and then it will push the commutator with an undersized inner ring or different coaxiality to move and fall off the assembly table 1, completing the rejection of unqualified commutators and avoiding damaging the rotor core during press-fitting. If the commutator is qualified, the detection rod 272 will pass through the inner ring of the commutator, and the commutator will not move. As the rotating disk 10 rotates counterclockwise, when the convex rod 22 rotates from the rightmost side to the uppermost side, the second spring 34 pulls the second slider 271 to the side close to the rotating disk 10. At this time, the detection rod 272 is withdrawn from the commutator, and the first spring 28 in the first sleeve 23 retracts. When the convex block 241 rotates to the uppermost end, the second slider 271 is on the side of the fixed ring 21 close to the rotating disk 10. At this time, the springs in the first sleeve 23 and the second sleeve 26 are both in the normal state. As the rotating disk 10 continues to rotate, the convex rod 22 rotates from the uppermost side to the leftmost side. At this time, the first slider 25 is pushed by the first sleeve 23 and the first rod core 24 to move away from the rotating disk 10. At this time, the first slider 25 pushes the push rod 32 to move and press the qualified commutator onto the rotor core. As the convex rod 22 moves from the leftmost side to the lowermost side, when the convex rod 22 rotates from the lowermost side to the rightmost side, the driving disk 12 drives the driven disk 15 to rotate 45 degrees, that is, when the rotating disk 10 rotates 360 degrees, the driven disk 15 rotates 45 degrees. At this time, the workpieces at the detection station and the assembly station both move forward one step for the next operation.

[0031] Further, a rotating ring 31 is rotatably provided on the assembly table 1. The rotating ring 31 is rotatably connected to the fixed ring 21. Four first clamping plates 36 are fixedly provided on the rotating ring 31, and second clamping plates 37 are rotatably provided on each of the first clamping plates 36; the commutator is clamped by the first clamping plates 36 and the second clamping plates 37. Torsion springs are fixedly provided in one-to-one correspondence between each of the first clamping plates 36 and the second clamping plates 37. In the initial state, the second clamping plates 37 on the first clamping plates 36 are in the open state, so as to facilitate placing the commutator on the first clamping plates 36. When it is necessary to detect and press-fit the commutator, the second clamping plates 37 are closed on the corresponding first clamping plates 36 to limit the commutator.

[0032] Furthermore, a fixed arc plate 2 is fixedly arranged on the assembly table 1, and the fixed arc plate 2 is fixedly connected to the fixed ring 21; the fixed ring 21 is fixed by the fixed arc plate 2, as Figure 1 shown, a first loading manipulator 3 for loading the commutator is fixedly arranged below the assembly table 1, and a unloading manipulator 4 for taking out the shaft core 11 and the commutator pressed together is fixedly arranged below the assembly table 1. A second loading manipulator 5 for loading the rotor core is fixedly arranged on the upper side of the assembly table 1. The first loading manipulator 3, the second loading manipulator 5, and the unloading manipulator 4 are all prior arts and will not be elaborated here. A notch is provided on one side of the fixed arc plate 2 close to the first loading manipulator 3. Combining Figure 1 , when the first clamping plate 36 and the corresponding second clamping plate 37 move perpendicular to the lower side of the assembly table 1 and close to the first loading manipulator 3, the second clamping plate 37 is in an open state. At this time, the unloading manipulator 4 takes off the assembled rotor core and commutator to complete the unloading. Then, the commutator is placed on the first clamping plate 36 by the first loading manipulator 3. As the rotating disk 10 rotates, the rotating ring 31 also rotates intermittently. When the first clamping plate 36 with the commutator installed rotates counterclockwise and moves to the fixed arc plate 2, the first clamping plate 36 and the second clamping plate 37 are closed by the abutment of the corresponding second clamping plate 37 of the fixed arc plate 2, thereby clamping the commutator. When the second clamping plate 37 is separated from the fixed arc plate 2, the second clamping plate 37 is automatically opened by the torsion spring, so as to facilitate the loading of the commutator. When the first clamping plate 36 and the second clamping plate 37 move counterclockwise to the left side closest to the assembly table 1, the commutator is detected by the detection rod 272. When the first clamping plate 36 and the second clamping plate 37 move counterclockwise to the upper side closest to the assembly table 1, the rotor core is loaded. When the first clamping plate 36 and the second clamping plate 37 move counterclockwise to the right side closest to the assembly table 1, the commutator is pressed onto the rotor core by the push rod 32. When the first clamping plate 36 and the second clamping plate 37 move counterclockwise to the lower side closest to the assembly table 1, the rotor core with the installed commutator is taken off and a new commutator is placed on the first clamping plate 36.

[0033] Specifically, a bearing ring 41 is rotatably arranged on the assembly table 1. The bearing ring 41 is rotatably connected to the rotating ring 31. A bearing plate 42 is fixedly arranged on the bearing ring 41. A baffle 43 is fixedly arranged on the assembly table 1; combining Figure 1, there are four carrier plates 42, which are evenly arranged on the carrier ring 41. The carrier plates 42 are used to place the rotor core. After the second loading manipulator 5 places the rotor core on the carrier plate 42, as the rotary disk 10 rotates one week, the rotary ring 31 is driven to rotate 45 degrees by the driven disk 15. When the rotary ring 31 rotates, it drives the carrier ring 41 to rotate 45 degrees at the same time, so that the commutator after detection and the carrier plate 42 with the rotor core installed move together to the side of the assembly table 1 close to the push rod 32. At this time, the commutator, the push rod 32, and the rotor core are coaxially aligned. At this time, the push rod 32 is retracted in the fixed disk, and the baffle 43 is at the rightmost side of the assembly table 1. When the commutator, the push rod 32, and the rotor core are coaxially aligned, the baffle 43 is behind the carrier plate 42 close to the push rod 32. As the rotary disk 10 rotates, the push rod 32 moves in the direction close to the baffle 43, so as to press-fit the commutator on the rotor core to complete the assembly of the commutator.

[0034] In another embodiment of the present invention: four discharging grooves 312 are symmetrically arranged on the rotary ring 31; when the commutator clamped between the first clamping plate 36 and the second clamping plate 37 moves to be coaxially aligned with the detection rod 272, the commutator stops moving. At this time, it is necessary for the rotary disk 10 to rotate one more week to make the commutator rotate 45 degrees around the axis of the rotary disk 10 again. When the rotary disk 10 rotates, it drives the detection rod 272 to extend towards the commutator. The inner wall surfaces of the first clamping plate 36 and the second clamping plate 37 are both treated with frosting that can increase friction. When the inner diameter of the commutator is small, the detection rod 272 will push the end of the commutator away from the carrier plate 42, so as to withdraw the commutator from the first clamping plate 36 and the second clamping plate 37. When the unqualified commutator is removed from the first clamping plate 36 and the second clamping plate 37, it falls from the rotary ring 31 through the discharging grooves 312, so as to complete the removal of the unqualified commutator. There are also four first clamping plates 36 on the rotary ring 31, which are aligned with the respective discharging grooves 312 one by one.

[0035] Specifically, a clamping block 38 is slidably arranged in each second clamping plate 37, and a third spring 39 is arranged corresponding to each clamping block 38 and each first clamping plate 36; the number of the third springs 39 on each clamping block 38 is two and they are arranged symmetrically on both sides of the clamping block 38. After a commutator is placed on the first clamping plate 36, the second clamping plate 37 is closed on the first clamping plate 36. The clamping block 38 is extruded upward by the commutator. At this time, the clamping block 38 contracts into the second clamping plate 37, and the clamping block 38 abuts against the commutator. When the detection rod 272 is inserted into a commutator with different coaxiality, it will abut against the inner wall of the commutator and push the commutator to move. When the commutator moves out of the first clamping plate 36 and the second clamping plate 37, the third spring 39 makes the clamping block 38 move downward. Since the detection rod 272 is inserted into the inner ring of the commutator at this time, when the detection rod 272 moves back into the fixed disk, the downward-moved clamping block 38 abuts against the end of the commutator, thereby pushing the commutator out of the detection rod 272, and the commutator falls into the blanking chute 312.

[0036] In another embodiment of the present invention: a limit disk 13 is fixedly arranged on the driving disk 12, and a driving rod 14 is fixedly arranged on the driving disk 12. Four driving grooves 17 are formed on the driven disk 15; the four driving grooves 17 are symmetrically arranged. Four limiting grooves 16 capable of fitting with the outer rear surface of the limit disk 13 are symmetrically formed on the driven disk 15. When the driving disk 12 rotates, it drives the driving rod 14 to rotate around the axis of the rotating shaft 11. When the driving rod 14 rotates to the position of the driving groove 17, it will extend into the driving groove 17. As the driving disk 12 continues to rotate, the driven disk 15 is driven to rotate 45 degrees through the cooperation between the driving rod 14 and the inner wall of the driving groove 17. After the driven disk 15 rotates 45 degrees, the limiting groove 16 fits with the outer peripheral surface of the limit disk 13 again, thereby preventing the driven disk 15 from rotating accidentally and making the rotor core and the commutator unable to be aligned.

[0037] Specifically, a toothed ring 19 is rotatably arranged on the limit disk 13, a gear 18 meshing with the toothed ring 19 is fixedly arranged on the driven disk 15, and four connecting rods 44 are symmetrically and fixedly arranged on the toothed ring 19. Each connecting rod 44 is fixedly connected with the rotating ring 31; when the driving disk 12 drives the driven ring to rotate through the cooperation between the driving rod 14 and the driving groove 17, the driven ring drives the gear 18 to rotate, the gear 18 drives the toothed ring 19 to rotate, and the transmission ratio between the gear 18 and the toothed ring 19 is one to one. When the toothed ring 19 rotates, the rotating ring 31 is driven to rotate through each connecting rod 44, so that the rotating ring 31 drives the commutator to switch the processing station, realizing the feeding, detection and assembly of the commutator.

[0038] In another embodiment of the present invention: Four abutting blocks 48 are fixedly arranged on the bearing ring 41. A moving plate 45 is slidably arranged at one end of each connecting rod 44 away from the gear ring 19. An avoidance groove 451 is formed in each moving plate 45. When the moving plate 45 is pushed so that the moving plate 45 can abut against the abutting block 48 when passing through the abutting block 48, the bearing ring 41 can be driven to rotate by the abutting block 48 when the rotating ring 31 rotates, so that the rotor core and the commutator rotate together for station switching. When the unqualified commutator is pushed down into the blanking chute 312 at the detection rod 272, with the rotation of the rotating ring 31 and the bearing ring 41, the empty first clamping plate 36 and the second clamping plate 37 move to the push rod 32. At this time, the push rod 32 moves towards the first clamping plate 36. Since there is no commutator in the first clamping plate 36 and the second clamping plate 37, the push rod 32 extends into the first clamping plate 36 and the second clamping plate 37 at this time, and pushes the moving plate 45 in the direction away from the gear ring 19, so that the avoidance groove 451 is aligned with the abutting block 48. At this time, when the rotating ring 31 rotates 45 degrees, the bearing ring 41 will not rotate, and the abutting block 48 will pass through the avoidance groove 451, thereby preventing the rotor core without an assembled commutator from moving to the blanking manipulator 4 and being taken out. With the rotation of the rotating ring 31, the first clamping plate 36 clamping the qualified commutator moves to the position of the rotor core without an assembled commutator, thereby realizing automatic replenishment after automatic rejection of unqualified products.

[0039] Specifically, four sliding grooves 311 are formed in the rotating ring 31, and a contact rod 452 is slidably arranged in each sliding groove 311. Each contact rod 452 is fixedly connected to each moving plate 45 in a one-to-one correspondence. A second spring 34 is fixedly arranged between the first slider 25 and the push rod 32. A contact plate 33 is fixedly arranged at one end of the push rod 32 close to the first slider 25. An inclined plate 47 and a triangular plate 46 are fixedly arranged in the assembly table 1;When the commutator axis is aligned with the axis of the detection rod 272, there is no rotor core on the carrier plate 42 on the carrier ring 41. When the commutator detection is completed, the rotor core is placed on the carrier plate 42 by the second loading robot 5. At this time, the axis of the rotor core is above the corresponding avoidance groove 451. In the initial state, the avoidance groove 451 on each movable plate 45 is aligned with the abutment block 48. At this time, the rotation of the rotating ring 31 will not drive the carrier ring 41 to rotate. When the first clamping plate 36 and the second clamping plate 37 are about to move to the push rod 32, the movable plate 45 at the bottom of the rotating ring 31 abuts against the inclined plate 47, and the movable plate 45 is pushed to move by the inclined plate 47, so that the avoidance groove 451 of the movable plate 45 is staggered with the abutment block 48. When the first clamping plate 36 and the second clamping plate 37 are about to move to the push rod 32, the movable plate 45 at the bottom of the rotating ring 31 abuts against the inclined plate 47. When the plate 36 and the second clamping plate 37 move to the push rod 32, the moving plate 45 just abuts against the abutment block 48 and separates from the inclined plate 47. The rotating disk 10 that continues to rotate drives the push rod 32 to move in the direction close to the first clamping plate 36 and the second clamping plate 37. If there is a commutator in the first clamping plate 36 and the second clamping plate 37 at this time, the push rod 32 pushes the commutator to move toward the axis of the rotor core and inserts the end of the axis into the inner ring of the commutator. The rear of the rotor core abuts against the baffle 43, and the second spring 34 is gradually compressed. As the first slider 25 moves, the first slider 25 pushes the push rod 32 to move in the direction close to the baffle 43, so that the axis of the rotor core is inserted into the inner ring of the commutator and the installation is completed. Due to the abutment of the commutator, the push rod 32 will not be completely The first clamping plate 36 and the second clamping plate 37 are fully extended into the first clamping plate 36 and the second clamping plate 37, so that the abutment plate 33 will not abut against the abutment rod 452, and the movable plate 45 remains in a state of abutting against the corresponding abutment block 48. At this time, the rotation of the rotating ring 31 can push the abutment block 48 through the movable plate 45 and drive the bearing ring 41 to rotate. A fixed rod 453 is fixedly arranged at the bottom of the movable plate 45. The fixed rod 453 is slidably connected with the connecting rod 44 and extends out from the bottom of the connecting rod 44. When the rotating ring 31 drives the bearing ring 41 to rotate 45 degrees, the fixed rod 453 is pushed through the triangular plate 46 and drives the movable plate 45 to move, so that the avoidance groove 451 on the movable plate 45 gradually coincides with the abutment block 48. When the bearing ring 41 and the rotating ring 31 rotate 45 degrees, the avoidance groove 451 is not rotated. 51 is just aligned with the abutment block 48, that is, the moving plate 45 can only drive the abutment block 48 and the carrying ring 41 to rotate at the push rod 32, so that whether the carrying ring 41 follows the rotating ring 31 depends on whether there is a commutator in the first clamping plate 36 at the push rod 32. When there is no commutator in the first clamping plate 36 and the second clamping plate 37 at the push rod 32, the first slider 25 pushes the push rod 32 to move, and the push rod 32 will fully extend into the first clamping plate 36. At this time, the abutment plate 33 abuts against the abutment rod 452, thereby pushing the moving plate 45 to move, so that the avoidance groove 451 of the moving plate 45 is aligned with the abutment block 48. At this time, the rotation of the rotating ring 31 will not drive the carrying ring 41 to rotate, so that the rotor core without a commutator is waiting for assembly in situ. ;
