Description

Technical Field

[0001] This application belongs to the field of assembly equipment technology, and more specifically, relates to an assembly apparatus. Background Technology

[0002] Micro motors, also known as miniature motors, are motors with a diameter of less than 160mm or a rated power of less than 750mW. Micro motors are commonly used in control systems or transmission machinery loads to perform functions such as detection, analysis, amplification, execution, or conversion of electromechanical signals or energy.

[0003] A micro motor includes a stator, rotor, commutator, bushing, and housing. The stator, rotor, commutator, and bushing are all housed within the housing. The stator remains stationary during micro motor operation and its main function is to generate a magnetic field. The rotor rotates during micro motor operation and its main function is to generate electromagnetic torque and induced electromotive force, serving as the hub for energy conversion in the micro motor. The rotor includes a rotor shaft and a rotor core. The rotor core is fixedly fitted around the outer circumference of the rotor shaft. The commutator is fixedly fitted around the outer circumference of the rotor shaft and located on one side of the rotor core. Its main function is rectification to ensure that the direction of electromagnetic torque remains constant. The bushing is fitted around the outer circumference of the rotor shaft and located on the side of the rotor core furthest from the commutator. Its main function is to ensure that the rotor core is stably mounted on the housing and to prevent axial movement of the rotor core along the rotor shaft.

[0004] In existing technologies, before assembling a micro motor, one worker typically needs to manually apply glue to the outer circumference of the rotor shaft. Then, another worker needs to manually press the commutator onto the rotor shaft from the first end, so that the commutator fits onto the glued outer circumference, thus assembling the commutator to the rotor. Next, another worker needs to manually press a sleeve onto the rotor shaft from the second end, so that the sleeve fits onto the outer circumference, thus assembling the sleeve to the rotor. This method involves a dispersed sequence of steps, resulting in low assembly efficiency. Summary of the Invention

[0037] Reference Figures 1 to 6 To address the aforementioned problems, according to one aspect of this application, an embodiment of this application provides an assembly apparatus for assembling a rotor 1100 and a commutator 1200. The rotor 1100 includes a rotor shaft 1110 and a rotor core 1120 sleeved on the outer periphery of the rotor shaft 1110. The commutator 1200 is provided with a first through hole through which the rotor shaft 1110 passes.

[0038] The assembly device includes a base 100, a limiting part 200, and an assembly drive part 300. The limiting part 200 is disposed on the base 100 and has a rotor limiting groove 211. The assembly drive part 300 is disposed on one side of the rotor limiting groove 211, and its output end can reciprocate within the rotor limiting groove 211 along its extension direction. The limiting part 200 has a commutator blocking part disposed on the side of the rotor limiting groove 211 away from the assembly drive part 300, and is used to prevent the commutator 1200 from moving away from the rotor limiting groove 211. The rotor core 1120 moves in the direction of the positioning groove 211 during the assembly of the rotor 1100 and the commutator 1200. The rotor core 1120 is at least partially located in the rotor positioning groove 211 and can move along the extension direction of the rotor positioning groove 211. The rotor positioning groove 211 can limit the position of the rotor shaft 1110 so that the first through hole is opposite to the rotor shaft 1110. The commutator 1200 is mounted on the commutator blocking part. The output end of the assembly drive part 300 pushes the rotor 1100 toward the commutator 1200 so that the commutator 1200 is sleeved on the outer periphery of the rotor shaft 1110.

[0039] In this embodiment, the rotor core 1120 is coaxially arranged with the rotor shaft 1110, and the rotor core 1120 is fixedly sleeved on the outer periphery of the rotor shaft 1110. The limiting part 200 is a limiting seat, which is fixedly installed on the base 100 with screws, and the rotor limiting groove 211 is horizontally arranged.

[0040] In specific applications, when assembling the rotor 1100 and the commutator 1200, the rotor core 1120 is placed in the rotor limiting groove 211, and then the commutator 1200 is mounted on the commutator blocking part. At the same time, under the action of the rotor limiting groove 211, the first through hole is made coaxial with the rotor shaft 1110. Then, glue is applied to the outer peripheral surface of the rotor shaft 1110 near the commutator 1200. Finally, the assembly drive unit 300 is started. The output end of the assembly drive unit 300 pushes the rotor 1100 toward the commutator 1200. During this process, the rotor shaft 1110 will pass into the first through hole. After the commutator 1200 reaches the designated position on the rotor shaft 1110, the assembly drive unit 300 is stopped, and the assembly of the rotor 1100 and the commutator 1200 is completed. By using the assembly device of this application to assemble the rotor 1100 and commutator 1200, it is not necessary for workers to manually press the commutator 1200 into the rotor shaft 1110, which not only reduces the number of workers, but also reduces the amount of assembly work and improves assembly efficiency.

[0041] Reference Figures 2 to 4In this embodiment, the commutator 1200 includes a commutator mount 1210 and a commutator body 1220 disposed on the commutator mount 1210. The end face of the commutator body 1220 near the commutator mount 1210 is the first end face, and the end face of the commutator mount 1210 near the commutator body 1220 is the second end face. The projection surface of the first end face onto the second end face at least partially covers the second end face. The limiting part 200 is provided with a blocking groove 221. The blocking groove 221 is located on the side of the rotor limiting groove 211 away from the assembly drive part 300 and communicates with the rotor limiting groove 211. The rotor limiting groove 211 has a slot for communicating with the blocking groove 221. The groove wall on the blocking groove 221 opposite to the slot of the rotor limiting groove 211 is a blocking wall. During the assembly of the rotor 1100 and the commutator 1200, the first end face is at least partially in contact with the blocking wall to prevent the commutator 1200 from moving away from the rotor limiting groove 211. The blocking wall is the commutator blocking part.

[0042] In this embodiment, the commutator body 1220 is fixedly installed on one side of the commutator mount 1210. The first end face and the second end face are not only parallel but also coaxially arranged, and the area of ​​the first end face is larger than the area of ​​the second end face; the blocking groove 221 is horizontally arranged. The blocking groove 221 facilitates the blocking of the commutator 1200 from moving away from the rotor limiting groove 211.

[0043] Reference Figure 1 Figure 7 In this embodiment, the assembly device also includes a dispensing assembly 400. The dispensing assembly 400 includes a dispensing section, which includes a dispensing syringe 410 and a pressure member. The liquid outlet of the dispensing syringe 410 is located below the liquid inlet of the dispensing syringe 410 and between the rotor limiting groove 211 and the liquid inlet of the dispensing syringe. The pressure member is disposed on one side of the dispensing syringe 410 and communicates with the dispensing syringe 410 so that the liquid outlet of the dispensing syringe 410 dispenses glue outward.

[0044] In this embodiment, the dispensing syringe 410 is tilted so that the glue inside the dispensing syringe 410 can be sprayed out more smoothly from the liquid outlet of the dispensing syringe 410. The liquid outlet of the dispensing syringe 410 is located above the rotor limiting groove 211. The dispensing part is a conventional dispensing machine, and the pressure component is a pressure pump. The pump outlet of the pressure pump is connected to the dispensing syringe 410. The specific structure and connection method of the dispensing syringe 410 and the pressure pump are common knowledge to those skilled in the art and will not be described in detail here.

[0045] In practical applications, when assembling the rotor 1100 and commutator 1200, after arranging the rotor 1100 and commutator 1200, the pressurizing component is activated to spray the adhesive in the dispensing syringe 410 from the outlet end of the dispensing syringe 410 onto the outer circumferential surface of the rotor shaft 1110. Then, the assembly drive unit 300 is activated to fit the commutator 1200 onto the outer circumference of the rotor shaft 1110. By using the dispensing assembly 400 of this application, the need for workers to manually apply adhesive to the outer circumferential surface of the rotor shaft 1110 is avoided, further reducing the number of workers, reducing the amount of adhesive application work, and improving assembly efficiency.

[0046] Reference Figure 1 , Figure 5 and Figure 7 As an optional embodiment of this application, the dispensing assembly 400 further includes a dispensing drive unit, which includes a dispensing drive component 420, a dispensing moving component 430, and a dispensing fixing component 440. The dispensing fixing component 440 is fixedly mounted on the base 100. The dispensing moving component 430 is slidably disposed on the dispensing fixing component 440 in a direction that approaches or moves away from the rotor limiting groove 211. The dispensing syringe 410 is mounted on the dispensing moving component 430. The dispensing drive component 420 is drivenly connected to the dispensing moving component 430 to drive the dispensing moving component 430 to move in a direction that approaches or moves away from the limiting part 200.

[0047] In this optional configuration, the dispensing fixing component 440 is horizontally positioned, with its length direction perpendicular to the extension direction of the rotor limiting groove 211. The dispensing fixing component 440 is a dispensing fixing plate, which is fixedly mounted on the base 100 by screws. The dispensing moving component 430 is a dispensing moving seat. Connecting grooves are provided on both sides of the dispensing fixing plate along its length direction. Two opposing sliding strips are provided on the dispensing moving seat, each sliding strip corresponding to and slidably positioned within one of the two connecting grooves. The two sliding strips are adapted to the two connecting grooves, allowing the dispensing moving component 430 to slide on the dispensing fixing component 440 in a direction approaching or moving away from the rotor limiting groove 211. The dispensing driving component 420 is a cylinder, with its piston fixedly connected to the dispensing moving component 430. The dispensing drive unit is designed to facilitate the dispensing assembly 400 to move closer to or further away from the rotor limiting groove 211. This prevents the dispensing syringe 410 from remaining above the rotor limiting groove 211 when dispensing is not required on the rotor shaft 1110, thus avoiding situations where the glue in the dispensing syringe 410 falls into the rotor limiting groove 211. This ensures the cleanliness of the rotor limiting groove 211 and thus guarantees the smoothness of the rotor 1100's movement within the rotor limiting groove 211.

[0048] In this optional embodiment, the dispensing moving part 430 is provided with an installation through hole and a disassembly gap. The disassembly gap is located on one side of the installation through hole and communicates with the installation through hole. The dispensing syringe 410 includes a syringe body 711 and a connecting body. The connecting body is fixedly sleeved on the outer periphery of the syringe body 711 and passes through the installation through hole. The outer peripheral surface of the connecting body is adapted to the hole wall of the installation through hole. The dispensing moving part 430 is provided with two coaxially arranged threaded through holes. The two threaded through holes are respectively located on opposite sides of the disassembly gap and are both communicated with the disassembly gap. The dispensing moving part 430 is also provided with an installation screw that passes through one of the two threaded through holes and the disassembly gap in sequence and enters the other threaded through hole. The installation screw is threadedly connected to the hole wall of one threaded through hole and also threadedly connected to the hole wall of the other threaded through hole.

[0049] Specifically, the disassembly gap is located above the mounting through hole and extends beyond the dispensing moving part 430, and both threaded through holes are horizontally positioned. By using the mounting screws, mounting through holes, and disassembly gap described in this application to install the dispensing syringe 410, not only can the dispensing syringe 410 and the dispensing moving part 430 be detachably connected, but it also facilitates the adjustment of the tilt angle of the dispensing syringe 410.

[0050] Reference Figures 1 to 6 as well as Figure 8 In this embodiment, the assembly device is also used to assemble the rotor 1100 and the sleeve 1300. The sleeve 1300 is provided with a second through hole for the rotor shaft 1110 to pass through. The assembly device also includes a mounting part 500, which is located on the side of the limiting part 200 near the assembly drive part 300. The mounting part 500 is provided with a sleeve limiting groove 510 along the extension direction of the rotor limiting groove 211, and the sleeve limiting groove 510 communicates with the rotor limiting groove 211. The assembly drive part 300 includes a pushing member 320, which is provided with a through hole 321 for the rotor shaft 1110 to pass through. The pusher 320 can reciprocate within the sleeve limiting groove 510 and the rotor limiting groove 211 along the extension direction of the sleeve limiting groove 510. The pusher 320 is the output end of the assembly drive unit 300. During the assembly of the rotor 1100 and the sleeve 1300, the sleeve 1300 is at least partially located within the sleeve limiting groove 510. The sleeve limiting groove 510 can limit the position of the sleeve 1300 so that the second through hole is opposite to the rotor shaft 1110. The pusher 320 pushes the sleeve 1300 toward the rotor 1100 so that the sleeve 1300 is fitted onto the outer periphery of the rotor shaft 1110.

[0051] In this embodiment, the mounting part 500 is a mounting platform, which is fixedly mounted on the base 100 by screws. The sleeve limiting groove 510 is horizontally arranged, and the part of the sleeve 1300 located in the sleeve limiting groove 510 is in contact with the groove wall of the sleeve limiting groove 510 arranged along the extension direction of the sleeve limiting groove 510. The pushing member 320 is a pusher, and the diameter of the through hole 321 is equal to the diameter of the rotor shaft 1110. Of course, in other embodiments, the diameter of the through hole 321 may also be larger than the diameter of the rotor shaft 1110.

[0052] In specific applications, when assembling the rotor 1100, commutator 1200, and sleeve 1300, after arranging the rotor 1100 and commutator 1200, the sleeve 1300 is placed vertically in the sleeve limiting groove 510, and the second through hole is made coaxial with the rotor shaft 1110. Then, the driving pusher 320 is driven to move towards the commutator 1200. During this process, the sleeve 1300 will be sleeved on the rotor shaft 1110 and move towards the rotor core 1120 along the axial direction of the rotor shaft 1110. When the surface of the sleeve 1300 near the rotor core 1120 is in contact with the surface of the rotor core 1120 near the sleeve 1300, the driving pusher 320 is continued to move towards the commutator 1200 until the commutator 1200 is sleeved on the outer periphery of the rotor shaft 1110 and moves to the designated position. By using the mounting part 500 in this application to assemble the rotor 1100, commutator 1200 and sleeve 1300, it is avoided that workers need to manually press the sleeve 1300 into the rotor shaft 1110, which further reduces the number of workers, reduces the amount of assembly work, and improves assembly efficiency.

[0053] Reference Figure 1 , Figure 5 and Figure 7 In this embodiment, the assembly drive unit 300 also includes an assembly drive component 310. The assembly drive component 310 is fixedly installed on the base 100 and located on the side of the pusher 320 away from the limiting part 200. The output end of the assembly drive component 310 is driven to connect with the pusher 320 to drive the pusher 320 to reciprocate.

[0054] In this embodiment, the assembly drive 310 is a cylinder, and the piston of the cylinder is drivenly connected to the pusher 320. Furthermore, in this embodiment, to ensure a stable connection between the output end of the assembly drive 310 and the pusher 320, the assembly drive unit 300 also includes a connector. The connector is fixedly connected to the output end of the assembly drive 310 and to the end of the pusher 320 near the assembly drive 310. The connector is a coupling. Of course, in other embodiments, the connector can also be any other component that can be fixedly connected to both the output end of the assembly drive 310 and the end of the pusher 320 near the assembly drive 310.

[0055] Reference Figure 1 , Figure 6 , Figure 9 and Figure 10 In this embodiment, a sliding groove 520 is provided on the upper surface of the mounting part 500. The sliding groove 520 is located on the side of the sleeve limiting groove 510 away from the rotor limiting groove 211 and is connected to the sleeve limiting groove 510. The pushing member 320 can pass through the sliding groove 520 and the sleeve limiting groove 510 in sequence along the extension direction of the sleeve limiting groove 510 and enter the rotor limiting groove 211. The assembly device also includes a feeding assembly 600, which includes a feeding part 610. The feeding part 610 is embedded in the sliding groove 520 and can slide along the extension direction of the sliding groove 520. The upper surface of the feeding part 610 is provided with a placement area for placing the sleeve 1300. The groove 611 has two open walls that are opposite to the groove wall of the sliding groove 520, so that the pusher 320 can pass through the groove 611 and enter the sleeve limiting groove 510. During the assembly of the rotor 1100 and the sleeve 1300, the sleeve 1300 is placed vertically in the groove 611 so that the extension direction of the second through hole is parallel to the axial direction of the rotor shaft 1110. The loading part 610 slides along the extension direction of the sliding groove 520 to drive the groove 611 to move to the position communicating with the sleeve limiting groove 510, so that the pusher 320 pushes the sleeve 1300 toward the sleeve limiting groove 510.

[0056] In this embodiment, the slide 520 is horizontally arranged, and the extension direction of the slide 520 is perpendicular to the extension direction of the sleeve limiting groove 510; the upper surface of the feeding part 610 is flush with the upper surface of the mounting part 500, and the bottom of the placement groove 611 is flush with the bottom of the sleeve limiting groove 510, so that the pusher 320 can smoothly push the sleeve 1300 in the placement groove 611 to move into the sleeve limiting groove 510. The length of the placement groove 611 along the extension direction of the sleeve limiting groove 510 is the width of the placement groove 611. The width of the placement groove 611 is greater than or equal to the axial length of the sleeve 1300 and less than the diameter of the sleeve 1300.

[0057] In specific applications, when assembling the rotor 1100, commutator 1200, and sleeve 1300, after arranging the rotor 1100 and commutator 1200, the sleeve 1300 is placed vertically in the placement groove 611 so that the extension direction of the second through hole is parallel to the axial direction of the rotor shaft 1110. Then, the feeding part 610 is pushed to slide along the extension direction of the sliding groove 520. When the placement groove 611 moves to the position communicating with the sleeve limiting groove 510, the movement of the feeding part 610 is stopped. Then, the pushing member 320 is driven to move towards the commutator 1200, thereby fitting the sleeve 1300 onto the outer circumference of the rotor shaft 1110 and fitting the commutator 1200 onto the outer circumference of the rotor shaft 1110. By using the feeding section 610 of this application to convey the sleeve 1300, the sleeve 1300 can be kept vertical as it enters the sleeve limiting groove 510, thereby ensuring that the sleeve 1300 is stably and accurately fitted onto the outer circumference of the rotor shaft 1110, thus improving assembly efficiency.

[0058] Reference Figure 5 and Figure 7 In this embodiment, the feeding assembly 600 also includes a feeding drive 620, which is fixedly installed on the base 100 and driven to the feeding part 610 to drive the feeding part 610 to reciprocate along the extension direction of the slide groove 520.

[0059] In this embodiment, the loading drive 620 is a cylinder, and the piston of the cylinder is fixedly connected to the loading part 610. By using the loading drive 620 in this application, the need for workers to manually push the loading part 610 to move within the slide 520 is avoided, reducing workload and improving assembly efficiency.

[0060] Reference Figure 9 and Figure 10 As an optional embodiment of this application, the feeding part 610 is adapted to the chute 520. The feeding part 610 includes a support part and a feeding part. The support part is disposed below the feeding part, and the placement groove 611 is disposed on the feeding part. Both the support part and the feeding part are elongated. The projection of the surface of the support part near the feeding part onto the projection surface of the feeding part near the support part partially covers the surface of the feeding part near the support part. Correspondingly, the longitudinal section of the chute 520 is the same as the longitudinal section of the feeding part 610. This design allows the feeding part 610 to move more smoothly and steadily within the chute 520.

[0061] Reference Figures 9 to 13In this embodiment, the assembly device further includes a feeding assembly 700, which includes a feeding cylinder 710. The feeding cylinder 710 includes a cylinder body 711, a cylinder seat 712, and a cylinder cover 713. The cylinder body 711 is mounted on the mounting part 500 and has mounting holes at both its upper and lower ends. The cylinder cover 713 is detachably mounted on the upper part of the cylinder body 711 and corresponds to the mounting hole located at the upper end. The cylinder seat 712 is mounted in the mounting hole located at the lower end. The outer peripheral surface of the cylinder seat 712 is in contact with the inner wall of the cylinder body 711. A sleeve rolling limiting groove 7121 is provided along the circumference of the outer peripheral surface of the cylinder seat 712. The sleeve rolling limiting groove 7121 extends downward from the upper surface of the cylinder seat 712. The width of the sleeve rolling limiting groove 7121 is greater than the axial length of the sleeve 1300, and the width of the sleeve rolling limiting groove 7121 is less than the diameter of the sleeve 1300, so that the sleeve 1300... The sleeve 1300 rolls vertically within the sleeve rolling limiting groove 7121. A discharge groove 7122 is provided on the bottom of the sleeve rolling limiting groove 7121. The discharge groove 7122 is connected to the slide groove 520. The minimum length of the cross-section of the discharge groove 7122 is greater than or equal to the diameter of the sleeve 1300, and the minimum width of the cross-section of the discharge groove 7122 is greater than or equal to the axial length of the sleeve 1300. There is a first preset height between the bottom of the placement groove 611 and the bottom of the discharge groove 7122. The first preset height is greater than or equal to the diameter of the sleeve 1300. The discharge assembly 700 also includes a discharge driving part, which includes a toggle member 721. The toggle member 721 is rotatably disposed within the cylinder body 711 around the circumference of the cylinder body 711. There is a second preset height between the lower surface of the toggle member 721 and the upper surface of the cylinder seat 712. The second preset height is less than or equal to the axial length of the sleeve 1300.

[0062] In this embodiment, the lower surface of the cylinder body 711 is flush with the upper surface of the mounting part 500, the lower surface of the cylinder seat 712 is flush with the upper surface of the mounting part 500, the material discharge groove 7122 is a cuboid cavity, and the axial length of the sleeve 1300 is the thickness of the sleeve 1300.

[0063] In specific applications, when assembling the rotor 1100, commutator 1200, and sleeve 1300, after arranging the rotor 1100 and commutator 1200, the loading drive 620 drives the loading part 610 to move within the slide groove 520, so that the placement groove 611 is aligned with the unloading through groove 7122. Then, multiple sleeves 1300 are placed into the cylinder body 711 through the mounting hole located at the top of the cylinder body 711, and then the cylinder cover 713 is placed on the cylinder body 711. The sleeve 1300 is aligned with the mounting hole located on top. Then, the actuating element 721 is driven to rotate circumferentially within the sleeve body 711. As the actuating element 721 rotates, the sleeve 1300 within the sleeve body 711 is moved into the sleeve rolling limiting groove 7121. Simultaneously, because the width of the sleeve rolling limiting groove 7121 is greater than the axial length of the sleeve 1300, and the width of the sleeve rolling limiting groove 7121 is less than the axial length of the sleeve 1300... Because the diameter is 0, the sleeve 1300 moved into the sleeve rolling limiting groove 7121 will be vertically positioned, and the axial direction of the sleeve 1300 will be horizontal and perpendicular to the axial direction of the cylinder body 711. As the number of sleeves 1300 in the sleeve rolling limiting groove 7121 increases, the sleeves 1300 in the sleeve rolling limiting groove 7121 will gradually move to the position of the discharge groove 7122 and fall into the placement groove 611 by their own gravity. Next, the feeding drive 620 drives the feeding part 610 to continue sliding in the slide groove 520 along the extension direction of the slide groove 520. When the placement groove 611 moves to the position that communicates with the sleeve limiting groove 510, the feeding part 610 is stopped from moving. Then, the pusher 320 is driven to move toward the commutator 1200, so that the sleeve 1300 is fitted on the outer periphery of the rotor shaft 1110 and the commutator 1200 is fitted on the outer periphery of the rotor shaft 1110.

[0064] Reference Figure 1 and Figure 7 In this embodiment, the feeding drive unit also includes a feeding drive component 722. The feeding drive component 722 is disposed above the cylinder cover 713 and is drivenly connected to the actuating component 721 to drive the actuating component 721 to rotate around the circumference of the cylinder body 711 within the cylinder body 711.

[0065] In this embodiment, the feeding drive 722 is a geared motor, which is fixedly mounted on the top of the cylinder cover 713 with screws. The output shaft of the geared motor passes through the cylinder cover 713 and extends into the cylinder body 711. The feeding drive 722 facilitates the driving of the actuating member 721 to rotate inside the cylinder body 711, thereby improving the feeding efficiency of the sleeve 1300.

[0066] Reference Figure 9 and Figure 13In this embodiment, the actuating component 721 includes an actuating support 7211 and multiple actuating plates 7212. The actuating support 7211 is driven to be connected to the output end of the feeding drive component 722. There is a placement space for the sleeve 1300 between the lower surface of the actuating support 7211 and the upper surface of the cylinder seat 712. The multiple actuating plates 7212 are arranged on the actuating support 7211 along the circumference of the cylinder body 711. The lower surface of the actuating plate 7212 is in contact with the upper surface of the cylinder seat 712. The surface of the actuating plate 7212 near the inner wall of the cylinder body 711 is in contact with the inner wall of the cylinder body 711.

[0067] In this embodiment, when assembling the rotor 1100, commutator 1200, and sleeve 1300, the sleeve 1300 is placed in the placement space. Simultaneously, to reduce the weight of the actuating mount 7211 and thus more smoothly drive the multiple actuating plates 7212 to rotate, the actuating mount 7211 includes a mount body and multiple connecting bodies. The mount body is coaxially arranged with the cylinder body 711 and fixedly connected to the output shaft of the geared motor. Multiple connecting bodies are integrally formed on the outer periphery of the mount body along its circumference. The number of connecting bodies is the same as the number of actuating plates 7212, and they are arranged in a one-to-one correspondence. Four actuating plates 7212 are provided. To facilitate the assembly and disassembly of the actuating plates 7212 and the connecting bodies, screws are used to connect the actuating plates 7212 and the connecting bodies. Furthermore, to reduce the possibility of damage to the outer surface of the sleeve 1300 when the actuating plate 7212 moves the sleeve 1300 into the sleeve rolling limiting groove 7121, the actuating plate 7212 is made of plastic. The actuating plate 7212 facilitates the movement of the sleeve 1300 inside the cylinder body 711 into the sleeve rolling limiting groove 7121, thereby improving the feeding efficiency of the sleeve 1300.

[0068] Reference Figure 9 As an optional embodiment of this application, the cylinder cover 713 includes a cover body 7131 and a limiting body 7132. The limiting body 7132 is disposed below the cover body 7131. The cover body 7131 is mounted on the upper surface of the cylinder body 711. The limiting body 7132 is disposed inside the cylinder body 711. The outer peripheral surface of the limiting body 7132 is in contact with the inner wall of the cylinder body 711.

[0069] In this optional configuration, the limiting body 7132 and the cover body 7131 are integrally molded and coaxially arranged. The surface of the cover body 7131 near the limiting body 7132 is in contact with the upper surface of the cylinder body 711. This design of the cylinder cover 713 not only facilitates the mounting of the unloading drive component 722, but also makes it easy to detachably connect the cylinder cover 713 and the cylinder body 711.

[0070] Reference Figures 9 to 13As an optional embodiment of this application, the cylinder body 711 includes a cylinder body and a cylinder base. The cylinder base is sleeved on the outer periphery of the cylinder seat 712 and is integrally formed with the cylinder seat 712. The cylinder body and the cylinder base are fixedly connected by screws, and the cylinder base is fixedly connected to the mounting part 500 by screws. A first threaded hole for screws to be screwed into is provided on the upper surface of the cylinder body, a second threaded hole for screws to be screwed into is provided on the upper surface of the cylinder base, and a third threaded hole for screws to be screwed into is provided on the mounting part 500. The first threaded hole, the second threaded hole, and the third threaded hole are coaxially arranged. In addition, a limiting through hole is provided on the upper surface of the cover body 7131. The limiting through hole is correspondingly arranged and connected to the first threaded hole. The screw is screwed into the first threaded hole, the second threaded hole, and the third threaded hole through the limiting through hole. The engagement of the screw with the hole wall of the limiting through hole can restrict the rotation of the cover body 7131 on the cylinder body 711. In this optional embodiment, two screws are provided on the cylinder body 711, and the two screws are arranged opposite each other with the axis of the cylinder body 711 as the center.

[0071] Reference Figure 1 , Figure 2 and Figure 6 In this embodiment, the limiting part 200 includes a rotor limiting platform 210, a rotor limiting groove 211 disposed on the rotor limiting platform 210, and two groove walls on the rotor limiting groove 211 that are arranged opposite each other along the extending direction of the rotor limiting groove 211 to limit the rotation of the rotor 1100. The limiting part 200 also includes a commutator limiting platform 220, which is disposed on the side of the rotor limiting platform 210 away from the assembly drive part 300. A blocking groove 221 is disposed on the commutator limiting platform 220, and the blocking groove 221 includes a first groove segment and a second groove segment. The first groove segment is disposed on the side of the second groove segment away from the rotor limiting groove 211 and communicates with the second groove segment. During the assembly of rotor 1100 and commutator 1200, commutator mount 1210 is at least partially located in the first slot section, commutator body 1220 is at least partially located in the second slot section, the first end face is at least partially in contact with the bottom of the second slot section, and the bottom of the second slot section is a barrier wall.

[0072] In this embodiment, the rotor limiting platform 210 is fixedly mounted on the base 100 with screws. When assembling the rotor 1100 and the commutator 1200, the portion of the rotor core 1120 located within the rotor limiting groove 211 abuts against the groove wall of the rotor limiting groove 211 along its extension direction, to prevent the rotor core 1120 from swaying left and right when moving within the rotor limiting groove 211 along its extension direction. The commutator limiting platform 220 is fixedly mounted on the base 100 with screws. The second groove segment extends from the surface of the commutator limiting platform 220 near the rotor limiting platform 210 toward the interior of the commutator limiting platform 220, and the first groove segment extends from the bottom of the second groove segment toward the interior of the commutator limiting platform 220. The groove opening of the second groove segment near the first groove segment completely covers the groove opening of the first groove segment near the second groove segment.

[0073] When assembling the rotor 1100 and the commutator 1200, a portion of the outer peripheral surface of the commutator mount 1210 is in contact with the groove wall of the first groove segment, a portion of the outer peripheral surface of the commutator body 1220 is in contact with the groove wall of the second groove segment, and a portion of the first end face is in contact with the bottom of the second groove segment. Through the above design, the commutator 1200 can be stably mounted on the commutator limiting platform 220, thereby facilitating the smooth insertion of the rotor shaft 1110 into the first through hole of the commutator 1200, and thus enabling the rotor 1100 and the commutator 1200 to be assembled.

[0074] Reference Figure 6 As an optional embodiment of this application, the commutator limiting platform 220 is provided with an air intake hole 222. The air intake hole 222 extends from the bottom of the first groove section into the commutator limiting platform 220. The assembly device also includes an air intake component, and the intake end of the air intake component is connected to the air intake hole 222.

[0075] In this optional configuration, the air intake component is a vacuum generator, and the suction end of the vacuum generator is connected to the end of the air intake hole 222 away from the first slot section. When assembling the rotor 1100 and the commutator 1200, the air intake component is activated, which draws air from the air intake hole 222, and then the commutator body 1220 is mounted in the first slot section. By adopting the above design, the commutator body 1220 can be more stably mounted on the commutator limiting stage 220.

[0076] Reference Figure 2 and Figure 6 As an optional embodiment of this application, the assembly device further includes an adjusting member 800. An adjusting groove is provided on the commutator limiting platform 220. The adjusting groove is located on the side of the blocking groove 221 away from the rotor limiting groove 211 and is connected to the blocking groove 221. The outer peripheral surface of the adjusting member 800 is threadedly connected to the groove wall of the adjusting groove and can reciprocate along the extension direction of the adjusting groove.

[0077] In this optional configuration, the extension direction of the adjusting groove is parallel to the extension direction of the blocking groove 221, and the adjusting component 800 is an adjusting screw, the length direction of which is parallel to the extension direction of the adjusting groove. When assembling the rotor 1100 and commutator 1200, after arranging the rotor 1100 and commutator 1200, the assembly drive unit 300 is activated. The output end of the assembly drive unit 300 pushes the rotor 1100 toward the commutator 1200. As the rotor 1100 moves, the rotor shaft 1110 passes through the first through hole. Once the end of the rotor shaft 1110 near the commutator 1200 abuts against the end of the adjusting screw near the rotor limiting groove 211, the rotor shaft 1110 stops moving, and the assembly drive unit 300 stops operating. The adjusting component 800 facilitates adjustment of the commutator 1200's stopping position on the rotor shaft 1110.

[0078] Reference Figure 1 and Figure 5 In this embodiment, the assembly device further includes a control unit 900 and a jog switch 1000. The control unit 900 is electrically connected to the assembly drive unit 310, the dispensing drive unit 420, the loading drive unit 620, the unloading drive unit 722, and the pressure unit. The jog switch 1000 is mounted on the base 100 and is electrically connected to the control unit 900. The control unit 900 is a controller.

[0079] In practical applications, when assembling the rotor 1100, commutator 1200, and bushing 1300, the operator picks up the commutator 1200 with their left hand and the rotor 1100 with their right hand, placing the commutator 1200 in the blocking groove 221 and ensuring that part of its first end face is in contact with the bottom of the second groove section. Simultaneously, the suction device is activated to stably attach the commutator mount 1210 to the first groove section. The rotor core 1120 is then placed in the rotor limiting groove 211. After both the commutator 1200 and the rotor 1100 are in place, a single press of the jog switch 1000 is performed. A start signal is sent to the control unit 900, which then controls the assembly drive unit 310, dispensing drive unit 420, loading drive unit 622, unloading drive unit 722, and pressurizing unit to start. First, the dispensing drive unit 420 drives the dispensing moving part 430 to move towards the rotor limiting groove 211. After the dispensing syringe 410's liquid outlet end moves above the rotor shaft 1110, the pressurizing unit pressurizes the dispensing syringe 410 so that the glue inside the dispensing syringe 410 is sprayed from the dispensing syringe 410's liquid outlet end onto the outer circumferential surface of the rotor shaft 1110. After dispensing is completed, the dispensing... The drive unit 420 drives the dispensing moving part 430 to move away from the rotor limiting groove 211; at the same time, the loading drive unit 620 drives the loading part 610 to move to the position corresponding to the placement groove 611 and the unloading channel 7122, and the unloading drive unit 722 drives the actuating part 721 to rotate inside the cylinder body 711 to move the sleeve 1300 inside the cylinder body 711 into the sleeve rolling limiting groove 7121, and then convey it to the placement groove 611 through the unloading channel 7122. Subsequently, the loading drive unit 620 drives the loading part 610 to move to the placement groove 611 and the sleeve limiting groove 51. At position 0; finally, the drive unit 300 drives the pusher 320 to move toward the commutator 1200. During this process, the sleeve 1300 will be sleeved on the rotor shaft 1110 and move toward the rotor core 1120 along the axial direction of the rotor shaft 1110. When the surface of the sleeve 1300 near the rotor core 1120 is in contact with the surface of the rotor core 1120 near the sleeve 1300, the drive pusher 320 continues to move toward the commutator 1200 until the commutator 1200 is sleeved on the outer periphery of the rotor shaft 1110 and moves to the designated position.

[0080] As an optional embodiment of this application, the assembly device further includes four solenoid valves. One solenoid valve has its first end connected to the assembly drive unit 310 and its second end connected to an external air source. Another solenoid valve has its first end connected to the dispensing drive unit 420 and its second end connected to an external air source. A third solenoid valve has its first end connected to the feeding drive unit 620 and its second end connected to an external air source. The last solenoid valve has its first end connected to the suction end of the suction unit and its second end connected to the end of the suction hole 222 furthest from the first groove section. Three of the four solenoid valves connected to the assembly drive unit 310, the dispensing drive unit 420, and the feeding drive unit 620 are electrically connected to the control unit 900, thereby facilitating the control of the start and stop of the assembly drive unit 310, the dispensing drive unit 420, and the feeding drive unit 620.

[0081] As an optional embodiment of this application, the assembly device further includes a pressure regulating valve. The first end of the pressure regulating valve is connected to an external air source, and the second end is connected to three of the four solenoid valves that are connected to the assembly drive unit 310, the dispensing drive unit 420, and the loading drive unit 620. The pressure regulating valve reduces the possibility of damage to the assembly drive unit 310, the dispensing drive unit 420, and the loading drive unit 620 due to excessive air pressure.

[0082] In summary, the assembly apparatus provided in this embodiment has at least the following beneficial technical effects: When assembling the rotor 1100 and the commutator 1200, the rotor core 1120 is placed in the rotor limiting groove 211, and then the commutator 1200 is mounted on the limiting part 200, with part of the first end face fitting against the groove wall of the blocking groove 221 opposite to the groove opening of the rotor limiting groove 211. At the same time, the first through hole is coaxial with the rotor shaft 1110. Then, glue is applied to the outer peripheral surface of the rotor shaft 1110 near the commutator 1200. Finally, the assembly drive unit 300 is started, and the output end of the assembly drive unit 300 pushes the rotor 1100 toward the commutator 1200. During this process, the rotor shaft 1110 will pass into the first through hole. After the commutator 1200 reaches the designated position on the rotor shaft 1110, the assembly drive unit 300 is stopped, and the assembly of the rotor 1100 and the commutator 1200 is completed. By using the assembly device of this application to assemble the rotor 1100 and commutator 1200, it is not necessary for workers to manually press the commutator 1200 into the rotor shaft 1110, which not only reduces the number of workers, but also reduces the amount of assembly work and improves assembly efficiency.

[0083] The above are merely preferred embodiments of this application and are not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
