Description

Technical Field

[0001] This utility model relates to the field of motor assembly technology, and in particular to a motor base plate bushing press-fitting device. Background Technology

[0002] Currently, in the process of motor assembly, the press-fitting of the motor base plate bushing is the foundation of motor assembly. The bushing serves as the installation reference for the motor shaft, while the base plate supports and protects the entire motor, directly affecting the motor's operational stability and service life.

[0003] The base plate has a round hole and a mounting hole that matches the bushing. Traditional press-fitting equipment usually uses an automated assembly line operation to place the bushing on the press-fitting equipment and place the base plate on top of the bushing so that the mounting hole is aligned with the bushing. Then the base plate and bushing are pressed together. After pressing, the motor base plate falls into the feeding trough along the assembly line.

[0004] Regarding the aforementioned technologies, the different heights of the feeding trough and the pressing equipment can easily cause the assembled base plate and bushing to become misaligned due to impact when the base plate falls into the feeding trough, resulting in unstable installation and affecting the stability of subsequent motor component assembly. Utility Model Content

[0005] To improve the stability of motor assembly, this application provides a motor base plate bushing press-fitting device.

[0006] This application provides a motor base plate bushing press-fitting device, which adopts the following technical solution: A motor base plate bushing pressing device includes a base, a turntable rotatably connected to the base, a plurality of support seats arranged circumferentially on the turntable, the turntable rotating intermittently along its own axis, a feeding assembly for placing the bushing onto the support seats and a feeding assembly for placing the base plate on the base, a support plate 1 and a support plate 2, the base also having a lifting component 1 on the support plate 1, the output end of the lifting component 1 being connected to a pressure plate, the pressure plate moving with the lifting component 1 towards the support seats and pressing the base plate and bushing together, and a lifting component 2 on the support plate 2 and a driving component 1 for driving the lifting component 2 to move vertically. The output end of the lowering component two is connected to a suction cup for adsorbing the bottom plate. The lower end of the support plate two is provided with a discharge groove for outputting the bottom plate. A support rod is slidably connected to the base along the vertical direction, and a lifting component three is provided for driving the support rod to move. A buffer plate is provided at one end of the support rod that passes through the discharge groove. The buffer plate moves closer to or further away from the discharge groove with the support rod. When the suction cup discharges material, it is directly opposite the buffer plate. The buffer plate has discharge ports on both sides along the width direction of the discharge groove. The shortest distance between the discharge ports is less than the diameter of the bottom plate. A top rod is provided on the discharge groove that is directly opposite the discharge port. When the buffer plate contacts the discharge groove, the upper end of the top rod is higher than the buffer plate.

[0007] By adopting the above technical solution, under the support of the base, when the turntable rotates, it drives the support seat to rotate along the turntable axis. The support seat supports the bottom plate and the bushing. The first and second feeding components place the bushing and the bottom plate on the support seat in sequence. The bottom plate rotates with the turntable until it is directly opposite the first support plate. The first lifting component drives the pressure plate to move closer to the bottom plate. The pressure plate and the support seat cooperate to press and assemble the bushing and the bottom plate. When the support seat is directly opposite the unloading suction cup, the second lifting component drives the unloading suction cup to move closer to the bottom plate and suction... With the base plate attached, drive component one drives lifting component two to move laterally and move the feeding suction cup closer to the feeding trough. When the feeding suction cup is directly opposite the buffer plate, the base plate falls onto the buffer plate. Lifting component three drives the support rod closer to the base and moves the buffer plate closer to the top rod. The top rod passes through the feeding port and lifts the base plate, causing it to fall into the feeding trough and be conveyed along the feeding trough to the discharge end. This reduces the probability of misalignment between the base plate and the bushing caused by the collision between the base plate and the feeding trough, thereby improving the stability of the subsequent motor assembly.

[0008] Optionally, the feeding groove is provided with a guide groove along its length, and the bottom of the guide groove is provided with a guide hole that matches the bushing along the length of the feeding groove.

[0009] By adopting the above technical solution, the guide groove guides and supports the sliding of the bottom plate along the length of the feeding groove, and the guide hole limits the displacement of the bushing in the lateral direction, thereby limiting the bottom plate and further improving the stability of the bottom plate sliding.

[0010] Optionally, a buffer groove is provided in the middle part of the buffer plate, and the inner wall of the buffer groove is inclined from the edge of the buffer plate towards the middle.

[0011] By adopting the above technical solution, when the base plate falls onto the buffer plate, the buffer groove supports and limits the base plate, reducing the probability of the base plate falling off the buffer plate and improving the stability of the buffer plate's support for the base plate.

[0012] Optionally, the first feeding component includes a vibrating feeding plate and a conveying slide. The conveying slide is located on one side of the feeding plate and is connected to the discharge end of the vibrating feeding plate. The end of the conveying slide is directly opposite the axis of the turntable. The vibrating feeding plate sends the bushing to the discharge end. The conveying slide is used to continue to convey the bushing to the end. A stop is provided at the end of the conveying slide. A support plate three is provided on the base. A moving part one is provided on the support plate three. A lifting part four is connected to the output end of the moving part one. A limit plate is connected to the output end of the lifting part four. Claws are hinged on both sides of the limit plate along the length direction. The claws are used to clamp the bushing and place the bushing on the support base. The second feeding component has the same structure as the first feeding component. When the device is working, the bottom plate is placed on the support base through the second feeding component.

[0013] By adopting the above technical solution, the bushings are placed in batches into the vibrating feeding tray. Under the action of the vibrating feeding tray, the bushings enter the conveyor slide one by one along the vibrating feeding tray and are conveyed to the end by the conveyor slide. The stop block blocks the bushings, reducing the probability of the bushings falling off the conveyor slide. The moving part one drives the lifting part four to move closer to or away from the support seat along the turntable radially, so that the lifting part four drives the limiting plate closer to or away from the support seat. When the limiting plate is directly opposite the end of the conveyor slide, the lifting part four drives the limiting plate to move closer to the bushing. The gripper picks up the bushing and places it on the support seat. The turntable rotates and drives the support seat into the working range of the feeding assembly two. At this time, the bottom plate in the feeding assembly two is located at the end of the transmission belt.

[0014] Optionally, the base is provided with a detection part and a flipping part. When the turntable rotates, it drives the base plate to pass through the feeding assembly one, the feeding assembly two, the detection part and the flipping part in sequence. The detection part detects the base plate along the vertical placement direction, and the flipping part is used to flip the base plate with the opposite placement direction.

[0015] By adopting the above technical solution, when the support seat rotates with the turntable to face the detection unit, the detection unit detects the base plate along the vertical placement direction and makes a judgment on the placement direction of the base plate. The flipping unit flips the base plate with the incorrect placement direction so that the preset side of the base plate faces upward, which facilitates the correct pressing of the base plate and the bushing in the subsequent process.

[0016] Optionally, the base is also provided with an adjustment part one and an adjustment part two. The adjustment part one is located between the feeding component two and the detection part, and the adjustment part two is located between the flipping part and the support plate two. When the turntable rotates, it drives the bottom plate through the working range of the adjustment part one and the adjustment part two. The adjustment part one and the adjustment part two are used to grab the bottom plate and drive the bottom plate to rotate so that the opening of the bottom plate faces the preset direction.

[0017] By adopting the above technical solution, when the support base and the first adjustment part are aligned, the first adjustment part performs a preliminary adjustment of the base plate so that the opening of the base plate faces the preset direction, which facilitates the subsequent inspection and flipping of the base plate. When the support base and the second adjustment part are aligned, the second adjustment part adjusts the base plate again, which improves the accuracy of the base plate placement and reduces the probability of subsequent incorrect installation of the base plate and bushing.

[0018] Optionally, the feeding trough is provided with air outlet pipes at both ends along the width direction, and the air outlet pipes blow out airflow from the feeding end to the discharging end of the feeding trough.

[0019] By adopting the above technical solution, when the bottom plate falls into the guide groove, the air outlet blows air in the sliding direction of the bottom plate, pushing the bottom plate to slide towards the discharge end, reducing the probability of the bottom plate getting stuck in the guide groove and affecting the material discharge, which is conducive to improving the material discharge efficiency of the bottom plate.

[0020] Optionally, the pressure plate includes an outer column, an inner column, and an elastic element. The outer column is connected to an output end of the lifting component. The inner column is located inside the outer column and is slidably connected to the outer column vertically. The elastic element is located between the outer column and the inner column. In its natural state, the elastic element has a tendency to push the inner column away from the outer column.

[0021] By adopting the above technical solution, the lifting component drives the outer column to approach the support seat, and the outer column drives the inner column to approach the support seat and contact the base plate. The elastic component provides buffer space for the vertical movement of the inner column, reducing the probability of wear caused by the collision between the inner column and the base plate, and thus reducing the probability of damage caused by the collision between the outer column and the base plate.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. Supported by the base, the turntable rotates, causing the support seat to rotate along the turntable axis. The support seat supports the base plate and bushing. Feeding assembly one and feeding assembly two sequentially place the bushing and base plate onto the support seat. The base plate rotates with the turntable until it is directly opposite the support plate. Lifting component one drives the pressure plate towards the base plate. The pressure plate and support seat cooperate to press and assemble the bushing and base plate. When the support seat is directly opposite the unloading suction cup, lifting component two drives the unloading suction cup towards the base plate and suctions it. Drive component one drives lifting component two to move laterally and moves the feeding suction cup closer to the feeding trough. When the feeding suction cup is directly opposite the buffer plate, the bottom plate falls onto the buffer plate. Lifting component three drives the support rod closer to the base and moves the buffer plate closer to the top rod. The top rod passes through the feeding port and lifts the bottom plate, causing the bottom plate to fall into the feeding trough and be conveyed to the discharge end along the feeding trough. This reduces the probability of misalignment between the bottom plate and the bushing caused by the collision between the bottom plate and the feeding trough, thereby improving the stability of the subsequent motor assembly. 2. The guide groove guides and supports the sliding of the base plate along the length of the feeding groove, and the guide hole limits the lateral displacement of the bushing, thereby limiting the base plate and further improving the stability of the base plate sliding. 3. When the base plate falls onto the buffer plate, the buffer groove supports and limits the base plate, reducing the probability of the base plate falling off the buffer plate and improving the stability of the buffer plate's support for the base plate.

[0031] The present application will be further described in detail below with reference to all the accompanying drawings.

[0032] This application discloses a motor base plate bushing press-fitting device. Example

[0033] Reference Figure 1 A motor base plate bushing pressing device includes a base 1, on which a second driving component is provided. The second driving component can be a motor. The output end of the motor is coaxially fixedly connected to a turntable 11, which drives the turntable 11 to rotate intermittently. The base 1 is provided with a feeding assembly 2, a second feeding assembly, an adjustment part 1, a detection part, a flipping part, an adjustment part 2, a support plate 3, and a support plate 4 in sequence along the rotation direction of the turntable 11. Multiple support seats 16 are evenly installed on the turntable 11 in the circumferential direction. The base 1 supports the support seats 16 through the turntable 11. The turntable 11 drives the support seats 16 to move along the axis of the turntable 11. When the turntable 11 stops rotating, the support seats 16 are directly opposite the workstation to be processed.

[0034] Reference Figure 1The feeding assembly 2 includes a vibrating feeding plate 21 and a conveying chute 22. The vibrating feeding plate 21 includes a hopper for placing bushings and a feeding rail spirally arranged along the circumference of the hopper. A vibrating motor is provided at the lower end of the hopper. When the vibrating motor vibrates, it drives the bushings in the hopper to spirally rise along the feeding rail. When the bushings move along the feeding rail, the feeding rail screens the bushings, so that all bushings that move to the discharge end of the feeding rail are perpendicular to the base 1. The vibrating feeding plate 21 is prior art and will not be described in detail here.

[0035] Reference Figure 1 The conveyor chute 22 is fixed on one side of the vibrating feed plate 21 and moves towards the axis of the turntable 11 from the vibrating feed plate 21. Its end is directly opposite the support base 16. The conveyor chute 22 is hollow and its inner diameter height is greater than the height of the bushing. The inner diameter width of the conveyor chute 22 is greater than the diameter of the bushing. The conveyor chute 22 is connected to the discharge end of the material track. The bushings moving along the material track enter the conveyor chute 22 one by one.

[0036] Reference Figure 1 and Figure 2 The conveyor chute 22 is equipped with multiple air blowing pipes along its length. An air source, such as an air compressor, is installed on the base 1 to transmit high-speed airflow to the air blowing pipes. The air blowing pipes blow the bushings towards the discharge end, causing the bushings to move along the conveyor chute 22 towards the turntable 11. A stop 221 is provided at the discharge end of the conveyor chute 22 to block the bushings and reduce the probability of the bushings squeezing against each other and falling off the conveyor chute 22. The second feeding assembly has the same structure as the first feeding assembly 2.

[0037] Reference Figure 1 and Figure 2 A support plate 3 5 is installed on the base 1. The support plate 3 5 is located on one side of the conveyor slide 22 along the width direction. A moving part 1 51 is installed on the side of the support plate close to the conveyor slide 22. The output end of the moving part 1 51 is connected to a lifting part 4 52. The output end of the lifting part 4 52 is fixedly connected to a limit plate 53. The limit plate 53 is parallel to the conveyor slide 22. Both sides of the limit plate 53 along the length direction are hinged with grippers 54. The moving part 1 51 drives the lifting part 4 52 to move closer to or away from the axis of the turntable 11 radially. The lifting part 4 52 drives the limit plate 53 to move closer to or away from the support base 16 radially along the turntable 11. When the limit plate 53 is directly opposite the end of the conveyor slide 22, the lifting part 4 52 drives the limit plate 53 to move downward, so that the grippers 54 approach the bushing at the end of the conveyor slide 22. In this embodiment, both the moving part 1 51 and the lifting part 4 52 are cylinders.

[0038] Reference Figure 1 and Figure 2A driving component three is installed on the base 1. The driving component three can be a cylinder. The output end of the cylinder is connected to the gripper 54 and drives the two grippers 54 to move closer or further away from each other along the length of the limiting plate 53. When the grippers 54 move closer to each other, they grip the bushing near the stop block 221 at the discharge end of the conveyor slide 22. The lifting component four 52 drives the limiting plate 53 to rise. The limiting plate 53 drives the grippers 54 to rise. The moving component one 51 drives the lifting component four 52 to move closer to the support base 16. When the limiting plate 53 is directly opposite the support base 16, the lifting component four 52 drives the limiting plate 53 to move downward, so that the grippers 54 move closer to the support base 16. The driving component three drives the two grippers 54 to move further away from each other, so that the bushing is placed on the support base 16, thereby completing the placement of the bushing.

[0039] Reference Figure 1 and Figure 3 The base 1 is provided with a support plate 4 6, which is located on the side of the feeding assembly away from the feeding assembly 1 2. A moving part 2 61 is installed on the side of the support plate 4 6 near the conveyor slide 22. The output end of the moving part 2 61 is connected to a lifting part 5 62, and the output end of the lifting part 5 62 is connected to a feeding suction cup 63. The feeding suction cup 63 is connected to a negative pressure pump. The moving part 2 61 drives the lifting part 5 62 to move closer to or away from the axis of the turntable 11 radially. The lifting part 5 62 drives the feeding suction cup 63 to move closer to or away from the support base 16 radially along the turntable 11. In this embodiment, both the moving part 2 61 and the lifting part 5 62 are cylinders.

[0040] Reference Figure 2 and Figure 3 When the feeding suction cup 63 is directly opposite the discharge end of the conveyor slide 22, the lifting component 62 drives the unloading suction cup 43 to approach the bottom plate at the end of the conveyor slide 22. The negative pressure pump drives the unloading suction cup 43 to adsorb the bottom plate. The lifting component 62 drives the unloading suction cup 43 to move upward. The moving component 61 drives the lifting component 62 to move closer to the support seat 16. The lifting component 62 drives the unloading suction cup 43 to move closer to the support seat 16. When the unloading suction cup 43 is directly opposite the support seat 16, the lifting component 62 drives the unloading suction cup 43 to move closer. The negative pressure pump stops working, causing the bottom plate to fall into the support seat 16, thus completing the placement of the bottom plate.

[0041] Reference Figure 1 and Figure 4The first adjustment unit is located on the side of the fourth support plate 6 away from the third support plate 5, and the second adjustment unit is located on the side of the first feeding assembly 2 away from the second feeding assembly. The first adjustment unit includes a fifth support plate 7, a sixth lifting component, a first rotating component, and a suction cup 71. The fifth support plate 7 is mounted on the base 1, and the sixth lifting component is mounted on the side of the fifth support plate 7 near the turntable 11. The base 1 guides the vertical displacement of the sixth lifting component. The first rotating component is located below the sixth lifting component and is connected to the lower end of the sixth lifting component. The base 1 supports the sixth lifting component and the first rotating component through the fifth support plate 7. The suction cup 71 is located below the first rotating component and is connected to the output end of the first rotating component. The sixth lifting component drives the first rotating component to move vertically closer to or away from the support base 16, and the first rotating component drives the suction cup 71 to move closer to or away from the support base 16.

[0042] Reference Figure 1 and Figure 4 When the support base 16 and the support plate 7 are directly opposite each other, the lifting component 6 drives the suction cup 71 to approach the base plate and adsorb it through the rotating component 1. The rotating component 1 drives the suction cup 71 to rotate along its own axis, and the suction cup 71 drives the base plate to rotate and rotate the base plate to a preset angle, which facilitates subsequent processing of the base plate. The adjustment unit 2 has the same structure as the adjustment unit 1. The adjustment unit 2 adjusts the base plate after processing at the previous station to the preset angle.

[0043] Reference Figure 4 The detection unit and the flipping unit are located between the adjustment unit one and the adjustment unit two and are arranged sequentially along the rotation direction of the turntable 11. The detection unit includes a support plate six 8, a probe rod 81, and a lifting component seven. The support plate six 8 is set on the base 1, and the lifting component seven is installed on the side of the support plate six 8 near the turntable 11. The lifting component seven can be a cylinder, and the probe rod 81 is connected to the output end of the lifting cylinder. The base 1 supports and limits the lifting component seven and the probe rod 81 through the support plate six 8. The lifting component seven drives the probe rod 81 to move vertically closer to or away from the support base 16. If the probe rod 81 is inserted into the round hole, the bottom plate faces upward; otherwise, the bottom plate is placed incorrectly, which helps to improve the installation accuracy of the bottom plate and the bushing.

[0044] Reference Figure 1 and Figure 5The flipping unit includes a support plate 7 (9), a driving component 4, a driving component 5, a rotating plate 92, and a clamping plate 91. The support plate 7 (9) is mounted on the base 1. The driving component 4 is mounted on the side of the support plate 7 (9) near the turntable 11. The center of the rotating plate 92 is connected to the output end of the driving component 4. The driving component 4 can be a motor, which drives the rotating plate 92 to rotate vertically. The driving component 5 is mounted on the side of the clamping plate 91 near the turntable 11. The driving component 5 can be a cylinder, and the clamping plate 91 is connected to the output end of the cylinder. The base 1 supports the clamping plate 91 through the support plate 7 (9). When the base plate is installed in the wrong direction, the driving component 5 drives the clamping plate 91 to clamp the base plate, and the driving component 4 drives the rotating plate 92 to rotate along the axis. The rotating plate 92 drives the clamping plate 91 to rotate, which in turn causes the clamping plate 91 to drive the base plate to rotate, thereby completing the flipping of the base plate.

[0045] Reference Figure 6 and Figure 7 A drive component 42 is installed on the upper end of the support plate 3. The output end of the drive component 42 is coaxially fixedly connected to the pressure plate 32. The base 1 supports the drive component 42 and the pressure plate 32 through the support plate 3. The pressure plate 32 includes an inner column 322, an outer column 321 and an elastic element 323. The outer column 321 is connected to the output end of the drive component 42. The drive component 42 can be a cylinder. The outer column 321 is sleeved on the outside of the inner column 322. The elastic element 323 is located between the inner column 322 and the outer column 321 and connects the inner column 322 and the outer column 321. The elastic element 323 can be a spring. In its initial state, the spring has the tendency to push the inner column 322 away from the outer column 321, so that the inner column 322 slides vertically connected to the outer column 321. The outer column 321 guides and limits the vertical movement of the inner column 322, which helps to improve the stability of the sliding of the inner column 322.

[0046] Reference Figure 6 and Figure 7 The lifting component 31 drives the outer column 321 to move closer to or away from the support seat 16, thereby causing the outer column 321 to drive the inner column 322 to move closer to or away from the support seat 16. When the inner column 322 moves closer to the support seat 16, the support seat 16 pushes the inner column 322 to move upward. The spring provides a buffer space for the inner column 322 to avoid collision. The outer column 321 moves downward and cooperates with the support seat 16 to press the pressure plate and bushing, reducing the probability of the inner column 322 colliding with the support seat 16 and causing wear, which is beneficial to extending the service life of the device.

[0047] Reference Figure 6 and Figure 8A drive component 42 is installed on the side of the support plate 2 4 near the support base 16. The support plate supports and guides the drive component 42. The output end of the drive component 42 is connected to the lifting component 2 41. The output end of the lifting component 2 41 is connected to the unloading suction cup 43. The support plate 2 4 supports the lifting component 2 41 and the unloading suction cup 43 through the drive component 42. In this embodiment, both the lifting component 2 41 and the drive component 42 are motors.

[0048] Reference Figure 6 and Figure 8 The base 1 is provided with a feeding groove 12. The feeding groove 12 is inclined from the axis of the turntable 11 towards the edge of the base 1. Baffles are installed on both sides of the feeding groove 12 along the width direction and on the side near the turntable 11. When the bottom plate falls into the feeding groove 12, the baffles cover the bottom plate, reducing the probability of the bottom plate falling out of the feeding groove 12.

[0049] Reference Figure 6 and Figure 8 A support rod 13 is vertically slidably connected to the base 1. A lifting component 14 is installed on the base 1, and the output end of the lifting component 14 is connected to the support rod 13. The lifting component 14 drives the support rod 13 to move vertically closer to or away from the base 1. The lifting component 14 can be a cylinder. The base 1 supports and guides the support rod 13. The support rod 13 passes vertically through the feeding trough 12 and is fitted with a buffer plate 15. A buffer groove 151 is opened in the middle of the buffer plate 15. The bottom plate falls into the buffer groove 151, and the buffer plate 15 supports the bottom plate through the buffer groove 151, reducing the probability of the bottom plate slipping off the buffer plate 15.

[0050] Reference Figure 6 and Figure 8 The buffer plate 15 has a discharge port 152 on both sides along its length. Two push rods 121 are installed at the bottom of the discharge trough 12, which are directly opposite the discharge port 152. When the drive component 3 drives the support rod 13 to approach the base 1, the support rod 13 drives the buffer plate 15 to approach the bottom of the discharge trough 12. The push rods 121 gradually contact the bottom plate and lift the bottom plate, so that the bottom plate falls into the bottom of the discharge trough 12 and slides along the discharge trough 12 to the discharge end of the discharge trough 12. This reduces the impact force generated by the collision between the bottom plate and the discharge trough 12 and reduces the probability of relative misalignment between the bottom plate and the bushing affecting the stability of the subsequent motor assembly.

[0051] Reference Figure 6 and Figure 8 The bottom of the feeding trough 12 is provided with a guide groove 122 along its length. The guide groove 122 has a guide hole 123 that matches the bushing along its own length. When the bottom plate falls into the guide groove 122, the guide hole 123 guides and limits the bushing, thereby guiding and limiting the bottom plate as a whole, further reducing the probability of the bottom plate falling out of the feeding trough 12.

[0052] Reference Figure 6 and Figure 8 Air outlet pipes 124 are installed on both sides of the feed trough 12 along the width direction. The end of the air outlet pipe 124 away from the feed trough 12 is connected to an air compressor. The air compressor delivers high-speed airflow into the air outlet pipe 124. The airflow flows along the air outlet pipe 124 in an inclined direction towards the guide groove 122. The two air outlet pipes 124 work together to blow the bottom plate, pushing the bottom plate to move towards the discharge end, reducing the probability of the bottom plate getting stuck in the guide groove 122 and causing blockage, which helps to improve the stability of the device operation.

[0053] The implementation principle of the motor base plate bushing pressing device in this application embodiment is as follows: Under the support of the base 1, the driving component 2 drives the turntable 11 to rotate, and the turntable 11 drives the support seat 16 to rotate along the axial direction of the turntable 11. The bushing places the feeding component 1 2 on the support seat 16, and the base plate is placed on the support seat 16 by the feeding component 2. The adjusting part 1 rotates the base plate to a preset angle, the detection part detects the positive and negative directions of the base plate, the flipping part flips the incorrectly placed base plate, and the adjusting part 2 adjusts the base plate so that the mounting hole is aligned with the bushing. When the base plate rotates with the turntable 11 to be aligned with the support plate 1 3, the lifting component 1 31 drives the pressure plate 32 to press the base plate. When the base plate moves with the support seat 16 to be aligned with the support plate 2 4, the driving component 1 42 drives the lifting component 2 41 to rotate along the axial direction of the turntable 11. As the lifting component 41 moves closer to the support base 16, the lifting component 2 drives the unloading suction cup 43 to approach the support base 16. The unloading suction cup 43 adheres to the bottom plate. The lifting component 2 drives the unloading suction cup 43 away from the support base 16 and, driven by the lifting component 2, moves the unloading suction cup 43 closer to the unloading groove 12, dropping the bottom plate into the groove of the buffer plate 15. The lifting component 3 drives the support rod 13 closer to the base 1. The support rod 13 moves the buffer plate 15 closer to the top rod 121. The top rod 121 lifts the bottom plate, causing it to fall into the guide groove 122. During the unloading process, the buffer plate 15 reduces the falling height of the bottom plate and supports it, reducing the impact force generated by the collision between the bottom plate and the bottom of the unloading groove 12. This helps to reduce the probability of relative misalignment between the bottom plate and the bushing, thereby improving the stability of the subsequent assembly of the motor and the bottom plate.

[0054] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
