Description

Technical Field

[0001] This invention relates to the field of hub motor assembly equipment technology, and in particular to a hub magnet assembly equipment. Background Technology

[0002] To save space, most electric bicycles use hub motors, which require numerous magnets to be attached to the hub. The quality of magnet installation significantly impacts the performance and lifespan of the hub motor. Currently, magnets are mostly installed piece by piece manually or using automated equipment, which is relatively inefficient. Furthermore, the sequential assembly of magnets can lead to improper placement or even assembly failure due to the forces between them. Summary of the Invention

[0003] The purpose of this invention is to provide a wheel hub magnet assembly equipment, which can press magnets onto the wheel hub in one go, ensuring assembly quality. Moreover, the assembly of magnets can be automated, resulting in high assembly efficiency.

[0004] To achieve the above objectives, the present invention discloses a hub magnet assembly equipment, which includes a controller, a frame, a magnet feeding device, and a magnet pressing device;

[0005] The frame is equipped with a positioning seat for positioning and placing the wheel hub;

[0006] The magnet pressing device is mounted on a frame and includes a first moving mechanism and a pressing mechanism. The first moving mechanism drives the pressing mechanism to move. The pressing mechanism includes a pressing drive and a pressing assembly. The pressing assembly has several gripping stations for positioning and gripping magnets. The gripping stations are evenly distributed around the circumference of the pressing assembly. The pressing drive drives all gripping stations to move synchronously. The magnet pressing device cooperates with the positioning seat to synchronously press the magnets gripped by all gripping stations into the hub placed on the positioning seat.

[0007] The magnet feeding device is mounted on the frame and is used to feed magnets to the gripping station.

[0008] The first moving mechanism, the pressing drive, and the magnet feeding device are connected to the controller.

[0009] Preferably, the pressing assembly further includes a mounting bracket, a rotating shaft, a first circular seat, a second circular seat, a plurality of guide members, a plurality of first pushing members, a plurality of second pushing members, and a plurality of positioning members;

[0010] The rotating shaft is rotatably connected to and limited on the mounting bracket. The rotating shaft has a first threaded section and a second threaded section arranged sequentially along its length. The helical directions of the first threaded section and the second threaded section are opposite.

[0011] The first and second round seats are both slidably connected to the mounting bracket, and the sliding direction of the first and second round seats is the same as the length direction of the rotating shaft; the first round seat, the second round seat and the rotating shaft are coaxially arranged, the first round seat is threadedly connected to the first threaded segment, and the second round seat is threadedly connected to the second threaded segment;

[0012] The guide, positioning, first pusher, second pusher, and gripping station are arranged in a one-to-one correspondence, with the gripping station positioned on the positioning. One end of the guide is connected to the positioning, and the other end is slidably connected to the mounting bracket. The guides are evenly distributed around the rotating shaft, and the sliding direction of the guides is perpendicular to the center line of the rotating shaft. One end of the first pusher is rotatably connected to the positioning, and the other end is rotatably connected to the first circular seat. One end of the second pusher is rotatably connected to the positioning, and the other end is rotatably connected to the second circular seat. The first and second pushers are symmetrically arranged about the guide.

[0013] Preferably, the positioning member is further provided with a buffer member and a first elastic member. The buffer member is connected to the positioning member by an equal-height screw, and the buffer member can slide relative to the equal-height screw. The first elastic member presses against the buffer member and the positioning member. The gripping station is set on the buffer member.

[0014] Preferably, the gripping station consists of a positioning groove and an adsorption component that can be magnetically attracted to the magnet. The positioning groove is adapted to the shape of the magnet. The bottom of the positioning groove is provided with an installation groove for installing the magnetic component, and the magnetic component does not extend beyond the installation groove. A stepped surface supporting the magnet is formed between the positioning groove and the installation groove. The distance from the stepped surface to the opening of the positioning groove is not greater than the thickness of the magnet.

[0015] Preferably, the magnet feeding device includes a material tray and a lifting mechanism. The material tray is mounted on a frame and has several feeding slots for horizontally stacking magnets, baffles for limiting magnet position, and several discharging slots for guiding magnets. The discharging slots are evenly distributed around the circumference of the material tray, and each discharging slot corresponds to a gripping station. When the pressing mechanism approaches the magnet feeding device, the opening of the discharging slot along its length is directly opposite the gripping station. The depth of the discharging slot is not less than the thickness of the magnet and less than twice the thickness of the magnet. The feeding slots and discharging slots correspond to each other and are connected, and are perpendicular to each other. The baffles are positioned above the feeding slots. The lifting mechanism includes a lifting drive and push rods corresponding to the discharging slots. The push rods are slidably connected to the discharging slots, and the lifting drive drives all push rods to rise and fall synchronously. The baffles, discharging slots, and push rods work together to push the magnets placed in the discharging slots out of the discharging slots.

[0016] Preferably, the system further includes buffer components and positioning detection elements corresponding to the feed troughs. The buffer components are located on the side of the discharge trough away from the feed trough and include a telescopic rod, a roller, a second elastic element, and a limiting pin for limiting the travel of the telescopic rod. The telescopic rod is slidably connected to the material tray, and the sliding direction of the telescopic rod is directly opposite the feed trough. The roller is rotatably connected to the end of the telescopic rod near the feed trough, and the discharge trough has a clearance hole for the roller to pass through. One end of the second elastic element presses against the material tray, and the other end presses against the telescopic rod or roller. Under normal conditions, the roller partially extends out of the clearance hole. The telescopic rod has an elongated hole adapted to the limiting pin. One end of the limiting pin is connected to the material tray, and the other end is inserted into the elongated hole. The positioning detection element is located at the end of the telescopic rod away from the feed trough, and the telescopic rod can abut against the positioning detection element.

[0017] Preferably, the tray is provided with a magnetic suction element for magnetically attracting magnets, and the discharge trough is disposed on the magnetic suction element; or, the magnetic suction element is disposed at the connection between the discharge trough and the feed trough.

[0018] Preferably, the device further includes a rotary drive for driving the material tray to rotate and a locking assembly for locking the material tray, the material tray being rotatably connected to the frame; the locking assembly includes a locking cylinder and a locking block, and the material tray is provided with a locking hole that cooperates with the locking block for limiting.

[0019] Preferably, it also includes a shaping device, which includes a shaping drive assembly and a shaping seat. The shaping drive assembly is connected to a controller, and the shaping drive assembly drives the shaping seat to move up and down. The shaping seat cooperates with the positioning seat to shape the wheel hub.

[0020] The frame is also provided with a second moving mechanism, which is connected to the controller; at least one positioning seat is provided, and the second moving mechanism drives the positioning seat to move between the magnetic steel pressing device and the shaping device.

[0021] Preferably, it further includes an unloading device for removing the wheel hub from the positioning seat, the unloading device including a third moving mechanism and a gripping assembly for gripping the wheel hub, the third moving mechanism driving the gripping assembly to move; the third moving mechanism and the gripping assembly are connected to a controller.

[0022] The present invention has the following beneficial effects:

[0023] This invention uses a first moving mechanism to move the pressing mechanism above the magnet feeding device. The magnet feeding device can automatically feed magnets to the gripping stations. After all gripping stations on the pressing mechanism have positioned and gripped the magnets, the first moving mechanism moves the pressing mechanism above the positioning seat. The positioning seat positions the wheel hub, ensuring accurate alignment of the pressing mechanism. Before the pressing assembly is inserted into the inner ring of the wheel hub, the pressing drive first causes all gripping stations to retract inward synchronously. At this time, the magnets gripped by the pressing assembly will not contact the wheel hub. After the pressing assembly is inserted into the inner ring of the wheel hub, the pressing drive drives all gripping stations to extend outward synchronously, thus allowing the magnets to be pressed into the inner ring of the wheel hub in one go, completing the automatic assembly of the magnets with high efficiency. In addition, because the magnets are assembled in one go, a relatively stable magnetic field can be built between the magnets, ensuring the stability of the magnet positions and thus ensuring the quality of the magnet assembly.

[0054] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0055] like Figures 1-23 As shown, this invention discloses a hub magnet assembly equipment, which includes a controller, a frame 10, a shaping device 20, a magnet feeding device 40, a magnet pressing device 30, and an unloading device 50. The shaping device 20, the magnet pressing device 30, and the unloading device 50 are sequentially mounted on the frame 10, while the magnet feeding device 40 is mounted on the frame 10 and positioned close to the magnet pressing device 30. In this case, two magnet feeding devices 40 are provided, one on each side of the magnet pressing device 30, so that when one magnet feeding device 40 is replenished with magnets 61, the other magnet feeding device 40 can be used to ensure continuous production. Of course, only one set of magnet feeding devices 40 may be used. A second moving mechanism 11 and at least one positioning seat 12 are mounted on the frame 10. The positioning seat 12 is used to position and place the wheel hub 62 to ensure that the wheel hub 62 participates in the assembly process of the magnet 61 in a uniform posture. The wheel hub 62 can be placed on the positioning seat 12 manually or by an external mobile device. The second moving mechanism 11 drives the positioning seat 12 to pass through the shaping device 20, the magnet pressing device 30, and the unloading device 50 in a reciprocating or cyclical manner. In this case, the second moving mechanism 11 is a linear motion module based on a motor, which is prior art and will not be described in detail. The second moving mechanism 11 is connected to a controller. Of course, the second moving mechanism 11 can also adopt other structures such as a turntable. The unloading device 50 is used to remove the wheel hub 62 with the assembled magnet 61 from the positioning seat 12.

[0056] The shaping device 20 is used to shape the wheel hub 62 placed on the positioning seat 12, providing a good mounting base for the pressing of the magnet 61. Of course, if the shape of the wheel hub 62 can be guaranteed, the shaping device 20 can be omitted. In this case, the shaping device 20 includes a shaping drive assembly 21 and a shaping seat 22. The shaping drive assembly 21 consists of a guide assembly and a cylinder (or hydraulic cylinder), which is connected to a controller. The cylinder pushes the shaping seat 22 to move up and down, and the guide assembly is used to ensure the stability of the shaping seat 22 in the direction of movement. When the positioning seat 12 on which the wheel hub 62 is placed moves to directly below the shaping seat 22, the shaping seat 22 is pressed down, and the shaping seat 22 cooperates with the positioning seat 12 to stamp and shape the inner ring of the wheel hub 62. After shaping, the wheel hub 62 moves to below the magnet pressing device 30, waiting for the assembly of the magnet 61.

[0057] The magnet pressing device 30 includes a first moving mechanism 31 and a pressing mechanism. The first moving mechanism 31 drives the pressing mechanism to move. The first moving mechanism 31 includes a horizontal moving component and a vertical moving component. The horizontal moving component drives the vertical moving component to move back and forth between the magnet feeding device 40 and the second moving mechanism 11. The vertical moving component drives the pressing mechanism to move up and down, so that the pressing mechanism moves closer to the positioning seat 12 for magnet 61 assembly, or the pressing mechanism moves closer to the magnet feeding device 40 for magnet 61 feeding. Both the horizontal moving component and the vertical moving component are linear motion modules based on motors, which are existing technologies and will not be described in detail. Both the horizontal moving component and the vertical moving component are connected to a controller.

[0058] The pressing mechanism includes a pressing drive 32 and a pressing assembly 33. The pressing assembly 33 includes a mounting bracket, a rotating shaft 35, a first circular seat 361, a second circular seat 362, several guide members 371, several first push members 372, several second push members 373, and several positioning members 38, with each guide member 371, positioning member 38, first push member 372, and second push member 373 corresponding to the others. The positioning member 38 is provided with a gripping station for positioning and gripping the magnet 61.

[0059] The mounting bracket includes a first mounting platform 341, a second mounting platform 342, a third circular seat 343, and several guide posts. The first mounting platform 341, the second mounting platform 342, and the third circular seat 343 are arranged parallel to each other. The first mounting platform 341 is connected to the third circular seat 343 via guide posts, and the second mounting platform 342 is connected to either the first mounting platform 341 or the third circular seat 343 via guide posts. In this case, the second mounting platform 342 is connected to the first mounting platform 341 via guide posts, which makes the connection more convenient and less prone to interference. For ease of distinction, the guide post connecting the first mounting platform 341 and the third circular seat 343 is defined as the first guide post 344, and the guide post connecting the first mounting platform 341 and the second mounting platform 342 is defined as the second guide post 345. A through hole is provided on the third circular seat 343 for the second guide post 345 to pass through.

[0060] The rotating shaft 35 rotatably connects and limits the first mounting platform 341 and the second mounting platform 342, meaning the rotating shaft 35 can only rotate on its own axis and cannot move along its length. A first threaded section 351 and a second threaded section 352 are sequentially arranged along the length of the rotating shaft 35. The helical directions of the first threaded section 351 and the second threaded section 352 are opposite; for example, the external thread on the first threaded section 351 is clockwise, and the external thread on the second threaded section 352 is counterclockwise. The first threaded section 351 and the second threaded section 352 can be considered as mirror images of each other with respect to the third circular seat 343. Furthermore, one end of the rotating shaft 35 extends a certain distance beyond the first mounting platform 341 to facilitate the transmission connection of the pressing drive component 32. The pressing drive component 32 is a motor connected to a controller. The first mounting platform 341 can be used as a connection point for the first moving mechanism 31.

[0061] The first circular seat 361 is positioned between the first mounting platform 341 and the third circular seat 343, and is parallel to the first mounting platform 341. The first circular seat 361 is slidably connected to the first guide post 344. The first circular seat 361 has a guide hole adapted to the first guide post 344 and a through hole for the second guide post 345 to pass through. This arrangement ensures stable movement of the first circular seat 361. The second circular seat 362 is positioned between the third circular seat 343 and the second mounting platform 342, and is parallel to the second mounting platform 342. The second circular seat 362 is slidably connected to the second guide post 345. The second circular seat 362 has a guide hole adapted to the second guide post 345. This arrangement ensures stable movement of the second circular seat 362. The movement directions of the first circular seat 361 and the second circular seat 362 are the same as the length direction of the rotating shaft 35. The first round seat 361, the second round seat 362 and the rotating shaft 35 are coaxially arranged. The first round seat 361 is threaded to the first threaded section 351, and the second round seat 362 is threaded to the second threaded section 352. Due to the guide post, the first round seat 361 and the second round seat 362 will not rotate. When the rotating shaft 35 rotates, the first round seat 361 and the second round seat 362 will move closer to or further away from each other.

[0062] Guide members 371 are evenly distributed around the rotating shaft 35. One end of each guide member 371 is slidably connected to a third circular seat 343, and the sliding direction of the guide member 371 is perpendicular to the center line of the rotating shaft 35. Guide holes corresponding to the guide members 371 are provided on the outer edge of the third circular seat 343. The other end of each guide member 371 is screwed to a positioning member 38. This arrangement ensures the stability of the movement direction of the positioning member 38. One end of the first pusher 372 is rotatably connected to the positioning member 38, and the other end of the first pusher 372 is rotatably connected to the first circular seat 361. One end of the second pusher 373 is rotatably connected to the positioning member 38, and the other end of the second pusher 373 is rotatably connected to the second circular seat 362. The first pusher 372 and the second pusher 373 are symmetrically arranged about the guide members 371. With this arrangement, when the rotating shaft 35 rotates, all the positioning members 38 can synchronously extend and retract outward under the linkage of the first pusher 372 and the second pusher 373. When the positioning component 38 retracts synchronously, the diameter of the circle formed by the magnets 61 gripped at the gripping station is smaller than the inner diameter of the hub 62. When the magnets 61 are assembled into the hub 62, the magnets 61 gripped by the pressing assembly 33 will not contact the hub 62, ensuring that the magnets 61 can reliably move into place. When the positioning component 38 extends synchronously, the gripped magnets 61 are pressed against the hub 62.

[0063] In a preferred embodiment, both the first pushing member 372 and the second pushing member 373 include a first ball head 374, a connecting rod 375, and a second ball head 376 connected in sequence. Both the first circular seat 361 and the second circular seat 362 include a first circular plate 363 and a second circular plate 365, which are detachable by screws. A plurality of first grooves 364 are evenly distributed around the outer edge of the first circular plate 363, the number of which matches the number of positioning members 38. The second circular plate 365 is provided with second grooves 366 corresponding one-to-one with the first grooves 364. The first grooves 364 and the second grooves 366 cooperate to form a first rotating hole 367. The first ball head 374 is rotatably connected and limited within the first rotating hole 367, meaning that the first ball head 374 can only rotate within the first rotating hole 367 and will not fall out of it. Correspondingly, a limiting member 381 is detachably connected to the positioning member 38 via screws. The positioning member 38 has a third groove 383, and the limiting member 381 has a fourth groove 382. The third groove 383 and the fourth groove 382 cooperate to form a second rotating hole 384, and the second ball head 376 is rotatably connected to and limited in the second rotating hole 384. In addition, the first round seat 361 and the second round seat 362 are both provided with a first limiting groove 368 that cooperates with the limiting of the connecting rod 375, and the limiting member 381 is provided with a second limiting groove that cooperates with the limiting of the connecting rod 375. By setting the first limiting groove 368 and the second limiting groove 385, it can be ensured that the positioning member 38 will not rotate, ensuring the installation stability of the positioning member 38, and facilitating a more neat arrangement of the magnets 61 gripped by the gripping station.

[0064] To facilitate the cooperation between the pressing assembly 33 and the magnet feeding device 40, and to better press the magnet 61 into the hub 62, a buffer 386 and a first elastic element 391 are provided on the positioning component 38. The buffer 386 is connected to the positioning component 38 via a height-equalizing screw 392, and the buffer 386 can slide relative to the height-equalizing screw 392. The first elastic element 391 is a spring, which presses against the buffer 386 and the positioning component 38. Under normal conditions, it is best if the spring is compressed to a certain extent. A positioning groove 387 adapted to the shape of the magnet 61 is provided on the buffer 386. An adsorption element 393 is provided at the bottom of the positioning groove 387 to adsorb and connect with the magnet 61. The positioning groove 387 and the adsorption element 393 constitute a gripping station. The adsorption force between the adsorption element 393 and the magnet 61 is less than the adsorption force between the magnet 61 and the hub 62, so that the magnet 61 can be detached from the gripping station without control.

[0065] Furthermore, the adsorption component 393 is made of a material that can be magnetically attracted to the magnet 61, such as a weak magnet or an iron block. A mounting groove 388 for mounting the adsorption component 393 is provided at the bottom of the positioning groove 387. A stepped surface 389 supporting the magnet 61 is formed between the positioning groove 387 and the mounting groove 388. The adsorption component 393 is positioned not beyond the mounting groove 388. This arrangement reduces the contact area between the magnet 61 and the adsorption component 393, facilitating the detachment of the magnet 61. Additionally, the distance from the stepped surface 389 to the opening of the positioning groove 387 is required to be no greater than the thickness of the magnet 61, ensuring that the magnet 61 can reliably attract the hub 62. Furthermore, the positioning component 38 is also made of a non-magnetic material to facilitate the detachment of the magnet 61. By setting the buffer 386 and the first elastic element 391, it is easier to grip and feed the magnet 61, and also easier to press the magnet 61 onto the wheel hub 62. When pressing the magnet 61, the buffer makes it less likely to damage the wheel hub 62. Of course, it can also be used without setting the buffer 386 and the first elastic element 391. In this case, the positioning groove 387 and the adsorption element 393 are set on the positioning element 38.

[0066] The magnet feeding device 40 is used to feed magnets 61 onto all gripping stations on the pressing assembly 33 in a single operation. It includes a material tray 41, a lifting mechanism, a rotary drive 43, and a locking assembly. The material tray 41 is rotatably connected to the frame 10 via bearings 45. The rotary drive 43 drives the material tray 41 to rotate. The rotary drive 43 can be a rotary joint (e.g., MQR4-M5) and is controlled by a controller. The locking assembly is used to lock the state of the material tray 41. It includes a locking cylinder 441 and a locking block. The locking cylinder 441 is connected to the controller. The material tray 41 has a locking hole 411 that engages with the locking block. The locking cylinder 441 drives the locking hole 411 to move relative to the material tray 41, allowing the locking block to be inserted into the locking hole 411, thereby locking the material tray 41. The rotation of the material tray 41 facilitates the replenishment of magnets 61 into it. The locking tray 41 is to ensure that the tray 41 and the pressing assembly 33 are aligned smoothly, and to ensure that the magnet 61 is fed smoothly.

[0067] The material tray 41 is provided with several feeding slots 412 for horizontally stacking magnets 61, baffles 413 for limiting the magnets 61, several discharging slots 414 for guiding the magnets 61, several buffer components, and several positioning detection elements 415. The discharging slots 414 are evenly distributed around the circumference of the material tray 41, and each discharging slot 414 corresponds to a gripping station. When the pressing mechanism approaches the magnet feeding device 40, the opening of the discharging slot 414 along its length is directly opposite the gripping station. The feeding slots 412 and discharging slots 414 correspond to each other and are connected, and the feeding slots 412 and discharging slots 414 are perpendicular to each other. The baffles 413 are located above the feeding slots 412 and abut against the edge of the discharging slots 414. In this case, the depth of the discharge trough 414 is required to be no less than the thickness of the magnet 61 and less than twice the thickness of the magnet 61, to ensure that only one magnet 61 can be pushed out of the discharge trough 414 at any given time. The tray 41 is equipped with a magnetic suction element 46 for magnetically attracting the magnet 61. The discharge trough 414 is positioned on the magnetic suction element 46, or the magnetic suction element 46 is positioned at the connection between the discharge trough 414 and the feed trough 412. With this configuration, the magnets 61 in the feed trough 412 can automatically move towards the discharge trough 414 and be attracted to it under the magnetic force of the magnetic suction element 46. When the magnets 61 are fed onto the tray 41, the rows of attracted magnets 61 are pushed to the discharge trough 414 to ensure automatic replacement of subsequent magnets 61. Except for the magnetic suction element 46, all components on the tray 41 are made of non-magnetic materials as much as possible to avoid affecting the automatic replacement of the magnets 61.

[0068] The feed chute 412, buffer assembly, and positioning detection element 415 correspond one-to-one. The buffer assembly is located on the side of the discharge chute 414 away from the feed chute 412 and includes a telescopic rod 416, a roller 417, a second elastic element 418, and a limiting pin 419. The telescopic rod 416 is slidably connected to the material tray 41, and the sliding direction of the telescopic rod 416 is directly opposite to the feed chute 412. The roller 417 is rotatably connected to the end of the telescopic rod 416 near the feed chute 412. A clearance hole 41a is provided on the discharge chute 414 for the roller 417 to pass through. One end of the second elastic element 418 presses against the material tray 41, and the other end presses against the telescopic rod 416 or the roller 417. Under normal conditions, under the force of the second elastic element, the roller 417 partially extends out of the clearance hole 41a. An elongated hole 41b, adapted to a limiting pin 419, is provided on the telescopic rod 416. One end of the limiting pin 419 is connected to the material tray 41, and the other end is inserted into the elongated hole 41b, thereby limiting the stroke of the telescopic rod 416. A positioning detection element 415 is located at the end of the telescopic rod 416 furthest from the feed trough 412, and the telescopic rod 416 can abut against the positioning detection element 415. When the magnet 61 is attracted to the discharge trough 414, it can overcome the elastic force of the second elastic element 418, causing the roller 417 to be pushed into the clearance hole 41a, and the telescopic rod 416 abuts against the positioning detection element 415, thus triggering a positioning signal. The positioning detection element 415 can be a negative pressure sensor, which determines whether the magnet 61 is in position by detecting the airtightness between the telescopic rod 416 and the negative pressure sensor. The positioning detection element 415 is connected to a controller. At this time, the rotary joint can serve as a transfer station for connecting the negative pressure sensor to the air pipe, preventing the air pipe from becoming tangled or even pulled out due to the rotation of the material tray 41. Only when all positioning detection elements 415 send positioning signals to the controller will the controller control the lifting mechanism to operate.

[0069] The lifting mechanism is used to push the magnet 61 placed in the discharge trough 414 and feed it into the positioning groove 387. The lifting mechanism includes a lifting drive component 421 and push rods 422 corresponding to the discharge trough 414. The push rods 422 are slidably connected to the discharge trough 414. A guide groove 41c that cooperates with the push rods 422 can be provided on the material tray 41 to ensure the stability of the sliding of the push rods 422. The lifting drive component 421 drives all push rods 422 to rise and fall synchronously. In this case, the lifting drive component 421 is a screw jack, which is connected to a controller.

[0070] After the pressing component 33 moves directly above the material tray 41, the positioning groove 387 corresponds to and is connected to the discharge. After all the positioning detection elements 415 have indicated that the magnet 61 is ready, the lifting mechanism pushes the push rod 422 to rise. Due to the obstruction of the baffle 413, the magnet 61 placed in the discharge groove 414 overcomes the attraction of other magnets 61 and is then peeled off and pushed out of the discharge groove 414, entering the positioning groove 387, thus realizing the feeding of the magnet 61. After the magnet 61 is loaded, the pressing assembly 33 moves above the second moving mechanism 11 and faces the positioning seat 12 where the hub 62 is placed. Then the pressing assembly 33 moves down. During this process, the first round seat 361 and the second round seat 362 move away from each other, causing the gripped magnet 61 to retract. The diameter of the circle formed by the magnet 61 is smaller than the inner diameter of the hub 62, so the pressing assembly 33 can be inserted into the inner diameter of the hub 62. After the toothed assembly moves into place, the first round seat 361 and the second round seat 362 move closer to each other, causing the gripped magnet 61 to extend outward. The magnet 61 can be attracted to the hub 62. Because the attraction force between the adsorption component 393 and the magnet 61 is less than the attraction force between the magnet 61 and the hub 62, when the first round seat 361 and the second round seat 362 move away from each other again, the magnet 61 is removed from the gripping position, and the pressing assembly 33 can be smoothly removed from the hub 62. The magnet 61 is assembled in one go.

[0071] The unloading device 50 is used to remove the wheel hub 62, after the magnet 61 has been assembled, from the positioning seat 12. The second moving mechanism 11 can either move the positioning seat 12 out of the pressing device before unloading, or the unloading device 50 can move directly under the pressing device for unloading. The unloading device 50 includes a third moving mechanism 51 and a gripping component 52 for gripping the wheel hub 62. The third moving mechanism 51 includes a horizontal moving module and a lifting moving module. The horizontal moving module drives the lifting moving module to approach or move away from the positioning seat 12 in the horizontal direction, while the lifting moving module drives the gripping component 52 to move up and down. The horizontal moving module and the lifting moving module are existing technologies and will not be described in detail. The gripping component 52 can be a gripper cylinder. Both gripper arms of the gripper cylinder are equipped with gripping blocks, which grip the outer ring of the wheel hub 62 to grip it. The horizontal moving module, the lifting moving module, and the gripper cylinder are connected to a controller.

[0072] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in the present invention should be included within the scope of protection of the present invention.
