Description

Technical Field

[0001] This invention relates to the field of parts conveying technology, and more specifically, to a conveying device for commutator assembly with automatic positioning. Background Technology

[0002] The commutator is an important component of the armature of DC motors and AC commutator motors. It performs a commutation function when the motor is rotating. It is a component in DC motors and AC series motors that performs current commutation to allow the motor to continue rotating; it is commonly known as a commutator.

[0003] Commutator assembly involves using automated equipment to insert the commutator onto the motor's output shaft. Since the commutator is cylindrical, it is placed vertically or tilted on the conveying equipment during assembly. This means that the automated assembly equipment needs to frequently adjust the commutator's position after picking it up, and the tilting angle of the commutator is also random, resulting in different adjustment methods each time, which greatly affects the commutator assembly efficiency.

[0004] Therefore, the commutator needs to be positioned when assembling it. However, the positioning of material conveying is different from the traditional positioning. Its purpose is to transport materials to the destination in a specific positional state.

[0005] Existing conveying equipment can adjust the position of rectangular objects and straighten them by using guide plates and push plates. However, when adjusting cylindrical objects such as commutators, the commutators can be either vertically aligned or tilted on the conveying table. This causes operational difficulties for the positioning mechanism on the existing conveying table. Therefore, how to position the commutator during the conveying process so that it always remains vertically aligned during conveying is a pressing problem that needs to be solved. Summary of the Invention

[0006] This invention provides a conveying device for commutator assembly with automatic positioning, which solves the technical problem in related technologies that the different placement states of commutators during conveying make it difficult to adjust their positioning and ensure that they are conveyed in a stable and upright state.

[0007] The present invention provides a conveying device for commutator assembly with automatic positioning, including a body and a conveying platform disposed on the top of the body, and a housing is fixedly connected to the front end of the body. The housing and the conveying platform are provided with a positioning adjustment component for positioning and adjusting the commutator to make it vertically upright.

[0008] The positioning adjustment assembly includes a partition fixedly connected to the middle of the box, which divides the box into two interconnected cavities. The left cavity inside the box has a first inclined surface, and the right cavity inside the box has a second and a third inclined surface. The surface of the first inclined surface has a movable groove for installing the first lifting unit and the second lifting unit. The first lifting unit and the second lifting unit are both inclined at the same angle as the first inclined surface. The left and right parts of the conveyor table are inclined in different directions.

[0009] As a further optimization of the present invention, a baffle is fixedly connected to the middle of the second inclined surface, and the rear end of the baffle extends to the top of the conveyor table. The distance between the baffle and the machine body is greater than the diameter of the commutator and less than the length of the commutator. The inclination angles at both ends of the conveyor table are five degrees.

[0010] As a further optimization of the present invention, the first lifting unit includes a first cylinder fixedly connected inside the movable slot, and the output end of the first cylinder is provided with a first lifting seat. The second lifting unit includes a second cylinder fixedly connected inside the movable slot, and the output end of the second cylinder is provided with a second lifting seat. The second lifting unit and the first lifting unit are arranged side by side in a stepped manner inside the movable slot.

[0011] As a further optimization of the present invention, the surface of the first lifting seat is provided with a rejection assembly, the rejection assembly including a rotating platform rotatably connected to the top of the first lifting seat, a slide platform slidably connected to the output end of the first cylinder inside the first lifting seat, and a slider fixedly connected to the front end of the slide platform, a sliding groove adapted to the slider is opened on the inner wall of the first lifting seat, a piston rod is fixedly connected to the top of the slide platform, and a sleeve slidably sleeved outside the piston rod is rotatably connected to the bottom of the rotating platform, and an exhaust hole is opened on the surface of the sleeve.

[0012] As a further optimization of the present invention, the rotary table is initially set at the same tilt angle as the first lifting seat, and after the rotary table rotates, it tilts at a five-degree angle with the front lower and the rear higher. The diameter of the exhaust hole is frustum-shaped and gradually decreases from the outside of the sleeve to the center. The length of the piston rod is the same as the sliding distance of the slider inside the slide groove.

[0013] As a further optimization of the present invention, the friction coefficient of the surfaces of the rotary table and the conveyor table is 0.15, and the inclination angles of the first inclined plane, the second inclined plane and the third inclined plane are all greater than ten degrees.

[0014] As a further optimization of the present invention, the interior of the second lifting seat is provided with a leveling component. The leveling component includes a positioning pin that slides through the top of the second lifting seat. The interior of the second lifting seat is fixedly connected to a limiting block that is fixedly connected to the output end of the second cylinder. A spring is fixedly connected between the positioning pin and the limiting block. A pull rope is fixedly connected to the bottom of the positioning pin, and the pull rope slides through the limiting block and is fixedly connected to the bottom of the movable groove.

[0015] As a further optimization of the present invention, the elastic force of the spring is greater than the frictional resistance between the positioning pin and the second lifting seat when the positioning pin slides. When the second lifting seat rises to the top, the pull rope pulls the positioning pin to retract into the interior of the second lifting seat.

[0016] As a further optimization of the present invention, a regular component is provided on the right side of the machine body. The regular component includes a third cylinder that is fixedly connected to the front end of the machine body by a connecting seat. The output end of the third cylinder passes through the connecting seat and is fixedly connected to a first stop block. The first stop block is fixedly connected to a second stop block by a connecting piece. A through slot is provided on the surface of the machine body for the first stop block and the second stop block to slide.

[0017] As a further optimization of the present invention, the first stop is L-shaped, the second stop is a flat plate structure, the connecting member is C-shaped and spans the top of the machine body, and the distance between the first stop and the second stop is adapted to the diameter of the commutator.

[0018] The beneficial effects of this invention are as follows:

[0019] 1. The automatic positioning conveying equipment for commutator assembly described in this invention ensures that all commutators conveyed to the assembly area are positioned and kept in a vertical state, facilitating subsequent assembly. This solves the problem of difficulty in positioning cylindrical materials during conveying, ensuring that materials are conveyed to the assembly area in a vertical state regardless of their orientation during the conveying process. It also prevents cylindrical materials from rolling off due to their tilted state during conveying, greatly improving assembly efficiency and conveying safety.

[0020] 2. The automatic positioning conveying equipment for commutator assembly described in this invention removes some tilted commutators in advance during the lifting process, thereby preventing excessive accumulation of commutators on the conveying table and affecting the sliding of tilted commutators back into the housing, thus improving the fault tolerance rate of the positioning adjustment component.

[0021] 3. The automatic positioning conveying equipment for commutator assembly described in this invention increases the proportion of vertically placed commutators on the conveying platform by pre-adjusting the vertical placement of the commutators, ensuring that the conveying efficiency is not affected, so that the commutators can be conveyed to the assembly area in a vertical state in a timely manner.

[0022] 4. The automatic positioning conveying device for commutator assembly described in this invention intermittently intercepts the commutator, allowing it to be conveyed regularly to the assembly area, maintaining consistency between conveying and assembly speeds, and improving assembly efficiency.

[0035] The subject matter described herein will now be discussed with reference to exemplary embodiments. It should be understood that these embodiments are discussed only to enable those skilled in the art to better understand and implement the subject matter described herein, and changes may be made to the function and arrangement of the elements discussed without departing from the scope of this specification. Various processes or components may be omitted, substituted, or added as needed in the examples. Furthermore, features described in some examples may be combined in other examples.

[0036] like Figures 1 to 5 As shown in the figure, a conveying device for commutator assembly with automatic positioning according to an embodiment of the present invention includes a body 10 and a conveying platform 11 disposed on the top of the body 10, and a housing 12 is fixedly connected to the front end of the body 10. The housing 12 and the conveying platform 11 are provided with a positioning adjustment component 20 for positioning and adjusting the commutator to make it vertically upright.

[0037] The positioning adjustment assembly 20 includes a partition 25 fixedly connected to the middle of the housing 12, which divides the housing 12 into two interconnected cavities. The left cavity inside the housing 12 has a first inclined surface 21, and the right cavity inside the housing 12 has a second inclined surface 26 and a third inclined surface 27. The surface of the first inclined surface 21 has a movable groove 22 for installing the first lifting unit 23 and the second lifting unit 24, and both the first lifting unit 23 and the second lifting unit 24 are inclined at the same angle as the first inclined surface 21. The left and right parts of the conveyor table 11 are inclined in different directions. The first lifting unit 23 includes a first cylinder 232 fixedly connected inside the movable groove 22, and the output end of the first cylinder 232 is provided with a first lifting seat 231. The second lifting unit 24 includes a second cylinder 242 fixedly connected inside the movable groove 22, and the output end of the second cylinder 242 is provided with a second lifting seat 241. The second lifting unit 24 and the first lifting unit 23 are arranged in a stepped manner, side by side, inside the movable groove 22.

[0038] A baffle 28 is fixedly connected to the middle of the second inclined surface 26, and the rear end of the baffle 28 extends to the top of the conveyor table 11. The distance between the baffle 28 and the machine body 10 is greater than the diameter of the commutator and less than the length of the commutator. The inclination angles at both ends of the conveyor table 11 are five degrees.

[0039] It should be noted that, firstly, the commutator to be conveyed is placed into the left-side cavity inside the housing 12. The commutator, once inside the left-side cavity, slides down the surface of the first inclined plane 21 to the upper end of the second lifting unit 24. Then, the second cylinder 242 pushes the second lifting seat 241 upwards, raising the commutator to the same height as the first lifting unit 23. At this point, under the action of the inclined plane at the top of the second lifting unit 24, the commutator slides to the top of the first lifting unit 23. Then, the first lifting unit 23 rises again, raising the commutator to the same height as the conveyor table 11. That is, the first cylinder 232 pushes the first lifting seat 231 upwards, and the commutator is lifted by the first lifting unit 24. The commutator slides down to the top of the conveyor platform 11 under the action of the top slope of the first lifting unit 23. Then, the commutator is conveyed from left to right by the conveyor platform 11. Since the left and right parts of the conveyor platform 11 are inclined in different directions, that is, the left part is inclined backward by five degrees and the right part is inclined forward by five degrees, when the commutator slides from the top of the first lifting unit 23 onto the conveyor platform 11, under the action of sliding inertia and in conjunction with the inclination of the left part of the conveyor platform 11, the commutator slides onto the conveyor platform 11 and then moves towards the rear end of the conveyor platform 11, so that the commutator is in contact with the body 10 at the rear end of the conveyor platform 11, thereby ensuring that the commutator follows a consistent path during the conveying process. After that, when the commutator... When the commutator moves to the right side of the conveyor platform 11, the commutator that was originally tilted forward and backward will collide with the baffle 28 during the conveying process because its length is greater than the distance between the baffle 28 and the machine body 10. Combined with the conveying of the conveyor platform 11, the baffle 28 pushes the commutator that was originally tilted forward and backward to tilt left and right. At this time, since the commutator has moved to the right side of the conveyor platform 11, and the right side of the conveyor platform 11 is tilted forward by five degrees, the commutator that was originally tilted left and right and the commutator that was adjusted to tilt left and right by the baffle 28 will slide off the conveyor platform 11 at the tilt angle. The slid-off commutator is guided by the second inclined surface 26 and the third inclined surface 27 again. The material falls into the cavity on the left side of the housing 12, and the above process is repeated. The vertically aligned commutator remains stably on the conveyor 11 due to the friction between its end plane and the conveyor 11, and is then conveyed by the conveyor 11. This ensures that the commutators conveyed to the assembly area are positioned and kept in a vertical state, which is convenient for subsequent assembly. This solves the problem of difficulty in positioning cylindrical materials during the conveying process. Regardless of the shape in which the material is placed during the conveying process, it can ultimately be conveyed to the assembly area in a vertical state. It also avoids the situation where cylindrical materials roll off due to their tilted state during the conveying process, which greatly improves the assembly efficiency and conveying safety.

[0040] like Figure 4As shown, the surface of the first lifting seat 231 is provided with a rejection component 30. The rejection component 30 includes a rotating platform 31 rotatably connected to the top of the first lifting seat 231. The interior of the first lifting seat 231 is slidably connected to a slide 32 fixedly connected to the output end of the first cylinder 232, and a slider 34 is fixedly connected to the front end of the slide 32. The inner wall of the first lifting seat 231 is provided with a sliding groove 33 adapted to the slider 34. The top of the slide 32 is fixedly connected to a piston rod 35. The bottom of the rotating platform 31 is rotatably connected to a sleeve 36 slidably sleeved outside the piston rod 35, and the surface of the sleeve 36 is provided with an exhaust hole 37.

[0041] The rotating platform 31 is initially set at the same angle as the first lifting seat 231, and after rotation, the rotating platform 31 tilts at a 5-degree angle with the front lower and the rear higher. The diameter of the exhaust hole 37 is frustum-shaped and gradually decreases from the outside of the sleeve 36 to the center. The length of the piston rod 35 is the same as the sliding distance of the slider 34 inside the slide groove 33. The coefficient of friction between the rotating platform 31 and the surface of the conveying table 11 is 0.15. The inclination angles of the first inclined surface 21, the second inclined surface 26 and the third inclined surface 27 are all greater than 10 degrees.

[0042] It should be noted that when the first lifting unit 23 pushes the commutator upward, the first cylinder 232 pushes the slide table 32 to slide upward inside the slide groove 33 using the slider 34. At this time, the piston rod 35 at the top of the slide table 32 slides into the sleeve 36, and squeezes the gas inside the sleeve 36 to the outside through the exhaust port 37. Since the exhaust port 37 has a frustum structure that is wider on the outside and narrower on the inside, the gas inside the sleeve 36 cannot be discharged in time. Therefore, the piston rod 35 pushes the sleeve 36 to rise synchronously, so that the sleeve 36 rises against the rotary table 31 and rotates with the connection point of the first lifting seat 231. After rotation, the rotary table 31 is tilted at a five-degree angle with the front lower and the rear higher, so that during the lifting of the commutator, it is tilted at a five-degree angle. The commutator that has tilted to the left and right slides back into the housing 12 along the tilt angle of the rotary table 31. Then, as the first lifting seat 231 continues to move upward, the gas inside the sleeve 36 is also vented. At this time, the sleeve 36 completely covers the piston rod 35. Under the action of gravity, the rotary table 31 returns to its initial state. After the first lifting seat 231 rises to the same height as the conveyor table 11, the commutator slides from the surface of the rotary table 31 onto the conveyor table 11. By removing some of the tilted commutators in advance during the lifting process, the accumulation of too many commutators on the conveyor table 11 is avoided, which would affect the sliding of the tilted commutators from the conveyor table 11 back into the housing 12. This improves the fault tolerance of the positioning adjustment component 20.

[0043] In addition, the surface friction coefficients of the conveyor table 11, rotary table 31, second lifting seat 241, first inclined surface 21, second inclined surface 26, and third inclined surface 27 were limited based on the material properties of the commutator, resulting in a surface friction coefficient of 0.15 for these areas. Based on this friction coefficient, experiments were conducted on the commutator at different tilt angles, and the experimental data are shown in the table below:

[0044] Inclined plane angle θ (degrees) tanθ (critical coefficient of friction) Has it slipped? 0 0.000 No slippage 1 0.017 No slippage 2 0.035 No slippage 3 0.052 No slippage 4 0.070 No slippage 5 0.088 No slippage 6 0.105 No slippage 7 0.123 No slippage 8 0.141 No slippage 9 0.158 slide 10 0.176 slide

[0045] Therefore, it can be seen that the vertically placed commutator will not slip when the tilt angle is five degrees. It will only slip when the tilt angle reaches nine degrees or more, thus ensuring the stability of the commutator in the vertical state at each stage of the transportation process.

[0046] like Figure 5 As shown, the second lifting seat 241 is provided with a leveling component 40 inside. The leveling component 40 includes a positioning pin 41 that slides through the top of the second lifting seat 241. The second lifting seat 241 is fixedly connected to a limiting block 42 that is fixedly connected to the output end of the second cylinder 242. A spring 43 is fixedly connected between the positioning pin 41 and the limiting block 42. A pull rope 44 is fixedly connected to the bottom of the positioning pin 41, and the pull rope 44 slides through the limiting block 42 and is fixedly connected to the bottom of the movable groove 22.

[0047] The elastic force of the spring 43 is greater than the frictional resistance between the positioning pin 41 and the second lifting seat 241 when the second lifting seat 241 slides. When the second lifting seat 241 rises to the top, the pull rope 44 pulls the positioning pin 41 to retract into the interior of the second lifting seat 241.

[0048] It should be noted that when the commutator is lifted using the second lifting unit 24, the second cylinder 242 first drives the second lifting seat 241 to perform high-frequency up-and-down reciprocating motion. During the downward movement, the second lifting seat 241 retracts into the interior of the movable slot 22. During this process, as the second lifting seat 241 moves up and down, it pushes the commutator inside the housing 12 to adjust its position, thereby allowing the positioning pin 41 on the surface of the second lifting seat 241 to be inserted into the hole of the commutator, initially limiting the steering gear to be placed vertically, until the second lifting seat 241 rises to the same height as the first lifting seat. At the same height 231, the pull rope 44 is taut and pulls the positioning pin 41 to retract into the interior of the second lifting seat 241 and squeezes the spring 43 with the limiting block 42, thereby releasing the restriction of the positioning pin 41 on the commutator, allowing the commutator to slide smoothly onto the first lifting seat 231. Then, as the second lifting seat 241 moves down, the spring 43 pushes the positioning pin 41 to reset, and the above operation is repeated. By adjusting the vertical placement of the commutator in advance, the proportion of vertically placed commutators on the conveyor table 11 is increased, ensuring that the conveying efficiency is not affected, so that the commutator can be conveyed to the assembly area in a vertical state in a timely manner.

[0049] like Figure 1 and Figure 6 As shown, a regular component 50 is provided on the right side of the body 10. The regular component 50 includes a third cylinder 52 fixedly connected to the front end of the body 10 by a connecting seat 51. The output end of the third cylinder 52 passes through the connecting seat 51 and is fixedly connected to a first stop block 53. The first stop block 53 is fixedly connected to a second stop block 55 by a connecting piece 54. A through slot 56 is provided on the surface of the body 10 for the first stop block 53 and the second stop block 55 to slide.

[0050] The first stop block 53 is L-shaped, the second stop block 55 is a flat plate structure, and the connector 54 is C-shaped and spans the top of the body 10. The distance between the first stop block 53 and the second stop block 55 is adapted to the diameter of the commutator.

[0051] It should be noted that because the commutators undergo positioning adjustments during transport, and tilted commutators are removed from the conveyor table 11, the spacing between commutators varies. In some areas, multiple commutators may converge, while in others, only a few may be present. However, the assembly speed of the assembly table remains consistent. When multiple commutators converge and are transported to the assembly area, they accumulate. Conversely, when only a few commutators are transported, the transport speed cannot keep up with the assembly speed. Therefore, deviations in the commutator transport speed affect assembly efficiency. Based on this, a regularization component 50 is implemented. In the initial state, the output end of the third cylinder 52 remains in a retracted state, the first stop 53 is inside the connecting seat 51, and the second stop... Block 55 passes through slot 56 and is located at the top of conveyor table 11 to block the commutator. Then, the third cylinder 52 intermittently drives the first stop block 53 to move back and forth. When the first stop block 53 moves towards conveyor table 11, it separates the subsequent commutators. The second stop block 55 retracts into slot 56 synchronously with the first stop block 53 using connector 54, so that the commutator that was originally blocked is transported to the assembly area. Then, when the first stop block 53 moves forward, the commutator that was originally blocked is transported to the position of the second stop block 55 and blocked by the second stop block 55. This process is repeated so that the commutator is regularly transported to the assembly area, maintaining the consistency of the transport and assembly speed and improving the assembly efficiency.

[0052] The embodiments of the present invention have been described above, but the embodiments are not limited to the specific implementation methods described above. The specific implementation methods described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of the embodiments described above, all of which are within the protection scope of the embodiments described above.
