Description

Technical Field

[0001] This invention relates to the field of rotor magnetization technology, specifically to a magnetization device and method for magnetizing both ends of a rotor. Background Technology

[0002] With the rapid development of the new energy vehicle industry, the demand for motors is increasing, and consequently, the demand for rotors used in motors is also growing. Furthermore, there is a wide variety of requirements for the types and styles of rotors. For example, some rotors only need to be magnetized on their outer periphery, while others only need to be magnetized on their end face.

[0003] Currently, the most common method is to magnetize the outer circumference of the rotor, while magnetizing the rotor end face is less common. Correspondingly, there are relatively more magnetizing devices for magnetizing the rotor circumference, but fewer for magnetizing the rotor end face. For magnetizing the rotor end face, it is not only necessary to make it easy for the magnetizing disk of the magnetizing mechanism to approach the rotor end face for stable magnetization, but also to make it easy to separate the disk surface of the magnetizing disk from the rotor end face after magnetization. These are all technical problems that need to be solved for end face magnetizing devices. Summary of the Invention

[0004] In view of the above, it is necessary for the present invention to provide a magnetizing device for magnetizing both end faces of a rotor.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A magnetizing device for magnetizing both ends of a rotor includes a base, a support mechanism, and a magnetizing mechanism. The support mechanism includes a support tube, which is rotatably mounted on the base about an axis. The top surface of the support tube is used to support the rotor.

[0007] The magnetization mechanism includes a lower end face magnetization structure and an upper end face magnetization structure arranged opposite to it, for magnetizing the upper and lower end faces of the rotor respectively. The lower end face magnetization structure includes a lower magnetization disk, which is vertically and flexibly sleeved on the support tube.

[0008] The upper end magnetization structure includes a lifting plate, a magnetization module, and a demolding rod. The lifting plate is movably positioned above the support tube. The magnetization module includes a lifting drive and an upper magnetizing disk. The lifting drive is mounted on the lifting plate, and the upper magnetizing disk is mounted below the lifting plate. The upper magnetizing disk is driven to move up and down relative to the lifting plate by the lifting drive. The demolding rod is fixedly positioned on the bottom surface of the lifting plate and passes downward through the magnetizing disk so that the magnetizing disk can move up and down along the demolding rod.

[0009] In addition, the present invention provides a magnetization method having the aforementioned magnetization device.

[0010] After the rotor is positioned on the support tube, the lifting cylinder lifts the lower charging disk upwards, so that the lower charging disk is close to the lower end face of the rotor; the lifting plate moves downwards, the demolding rod first presses against the upper end face of the rotor, and then the lifting drive pushes the upper charging disk to continue to descend along the demolding rod until the charging disk is close to the rotor, and the lower charging disk and the upper charging disk are activated to magnetize both ends of the rotor.

[0011] Furthermore, the present invention provides a rotor magnetization processing line having the aforementioned magnetization device.

[0012] A rotor magnetization processing line for magnetizing both ends of a rotor includes a conveyor line and a magnetization device. The conveyor line moves the rotor to be processed to a preset position, and the magnetization device picks up the rotor and magnetizes both ends of the rotor.

[0013] The beneficial effects of this invention are as follows: The magnetizing device for magnetizing both ends of a rotor provided by this invention positions the rotor on a support mechanism. A lower magnetizing disk, mounted on the support tube of the support mechanism, can be raised and lowered. When it rises to be flush with the top surface of the support tube, the lower magnetizing disk can fully magnetize the lower end of the rotor. An upper magnetizing structure is provided above the support tube. The upper magnetizing structure includes a demolding rod and a magnetizing module that can be raised and lowered relative to the demolding rod. After the magnetizing module magnetizes the upper end of the rotor, the demolding rod holds the module, facilitating separation between the magnetizing module and the rotor. This solves the problem of the rotor adsorbing the magnetizing disk after magnetization. The magnetizing device and rotor magnetizing processing line with the magnetizing device provided by this invention can magnetize both ends of the rotor, facilitate the magnetizing disk to approach the rotor end face for full magnetization, and achieve stable separation of the magnetizing disk from the rotor end face after magnetization. This solves the problem of magnetizing the rotor end face and greatly improves production efficiency. Attached Figure Description

Detailed Implementation

[0024] The specific embodiments of this application will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this application.

[0025] like Figures 1-4 As shown, this embodiment of the invention provides a rotor magnetization processing line for magnetizing the two end faces of a rotor, especially a disc-shaped rotor. The line includes a conveyor line 1 and a magnetization device 2. The conveyor line 1 moves the rotor to be processed to a preset position, and the magnetization device 2 picks up the rotor, magnetizes the two end faces of the rotor, and performs surface magnetization detection on the magnetized end faces of the rotor.

[0026] The conveyor line 1 includes a conveyor frame 11, a transfer plate 12, and a limiting and lifting mechanism 13. The conveyor frame 11 has two parallel tracks 111. The transfer plate 12 is slidably installed between the tracks 111 to carry the rotor and drive the rotor to move along the tracks 111 to a preset position. The transfer plate 12 can be driven to move on the tracks 111 by a conveying structure such as a belt (not shown). The limiting and lifting mechanism 13 is installed at one end of the conveyor frame 11 and located on one side of the magnetizing device 2. It is used to block the transfer plate 12 when it slides to the limiting and lifting mechanism 13, and to lift the rotor on the transfer plate 12 to a preset height for the magnetizing device 2 to remove.

[0027] The transfer plate 12 includes a plate body 121 and a column 122 fixed on the plate body 121. The plate body 121 is movably mounted on the track 111, and the rotor is inserted into the column 122 for positioning the rotor on the plate body 121.

[0028] The limiting lifting mechanism 13 includes a frame 131, a lifting pallet unit 132, a feeding stop 133, and a discharging stop 134. The lifting pallet unit 132 is located at the top of the frame 131 and is used to lift the transfer plate 12. The lifting pallet unit 132 includes a pallet and a lifting drive component, such as a cylinder or electric cylinder, located below the pallet. The top surface of the pallet has a plug-in structure for relative alignment and cooperation with the plate 121. A feed stop 133 is mounted on the frame 131 at one end of the pallet to allow the plate 121 to enter. A discharge stop 134 is vertically mounted on the frame 131 at the other end of the pallet to allow the plate 121 to exit. When the transfer plate 12, carrying the rotor, moves to contact the feed stop 133, the transfer plate 12 decelerates and stops when it is blocked by the discharge stop 134. The lifting drive of the lifting pallet unit 132 drives the pallet to rise, and the pallet rises to a preset height against the transfer plate 12 so that the magnetizing device 2 can remove the rotor. After the rotor is removed, the pallet descends, and the transfer plate 12 falls back onto the track 111, from which it can move back to its initial position.

[0029] The magnetizing device 2 includes a base 20 and a transfer mechanism 30, a magnetizing mechanism 40, a support mechanism 50, and a surface magnetization detection mechanism 60 mounted on the base 20. The base 20 is installed beside the conveyor frame 11. The transfer mechanism 30 picks up the rotor from the transfer plate 12 and transfers it to the support mechanism 50, which carries the rotor. The magnetizing mechanism 40 moves to the end face of the rotor and magnetizes the end face. After magnetization, the magnetizing mechanism 40 moves away from the end face of the rotor, exposing the end face. The surface magnetization detection mechanism 60 moves to the end face of the rotor, and the support mechanism 50 drives the rotor to rotate relative to the surface magnetization detection mechanism 60. The surface magnetization detection mechanism 60 performs surface magnetization detection on the end face of the magnetized rotor.

[0030] The base 20 includes a base 21 and a frame 22 mounted on the base 21. The top surface of the base 21 is provided with a detachable platform 211. The frame 22 includes side frames 221 arranged opposite each other and a top beam 222 connected between the side frames 221. The side frames 221 are located on both sides of the platform 211, and the top beam 222 is located above the platform 211. A space is formed between the two side frames 221 for the installation of the magnetization mechanism 40, the support mechanism 50, and the surface magnetization detection mechanism 60.

[0031] The transfer mechanism 30 includes a translation module 32, a lifting module 33, and a clamping module 34. The translation module 32 is mounted on one side frame 221, with one end extending outward to above the limiting lifting mechanism 13 of the conveyor line 1. The lifting module 33 is mounted on the translation module 32 and is driven to translate by the translation module 32. The clamping module 34 is mounted on the lifting module 33 and is driven to lift by the lifting module 33. Thus, the translation module 32 moves the clamping module 34 above the limiting lifting mechanism 13, and then the lifting module 33 lowers the clamping module 34, allowing it to clamp and transfer the rotor on the transfer plate 12.

[0032] Specifically, the clamping module 34 includes a liftable mounting plate 341 mounted on the lifting module 33, clamping arms 342 that are translatably disposed on the mounting plate 341, and a drive motor 343 for driving the clamping arms 342 to translate. Specifically, the shaft end of the drive motor 343 is connected to a lead screw, and rotating the lead screw drives the two clamping arms 342 to move in opposite directions or towards each other to achieve opening or clamping.

[0033] Please see Figure 3 , Figure 5 and Figure 6 The support mechanism 50 is used to support the rotor at a fixed height and drive the rotor to rotate. The support mechanism 50 includes a drive motor 52, a support tube 53, and a positioning component 54. The drive motor 52 is fixed to the bottom surface of the platform 211. The support tube 53 is used to support the rotor and can support the rotor on the top surface of the support tube 53. The support tube 53 is rotatably inserted into the platform 211 around its axis and extends downward to the bottom of the platform 211. A synchronous pulley is sleeved at the bottom end of the support tube 53, and a conveyor belt is provided to drive the synchronous pulley to the output shaft of the drive motor 52. The drive motor 52 drives the support tube 53 to rotate synchronously. The positioning component 54 is installed on the support tube 53 to perform angular positioning of the rotor and ensure that the rotor can be accurately installed on the support tube 53.

[0034] Specifically, please refer to Figure 6The positioning assembly 54 includes a crossbar 541, two insert rods 542, a center rod 543, and a spring. The crossbar 541 is radially installed inside the support pipe 53 and can slide a preset height along the axial direction of the support pipe 53. Specifically, an axial groove of a preset length is formed on the pipe wall of the support pipe 53, and the end of the crossbar 541 extends into the axial groove, thereby limiting the sliding distance of the crossbar 541 in the axial direction. The two insert rods 542 are slidably inserted into the grooves 531 on the peripheral wall of the support pipe 53 along the axial direction. The bottom ends of 2 are fixed to both ends of the crossbar 541, and the top end protrudes from the top surface of the support tube 53; the center rod 543 is fixedly connected to the center of the bottom surface of the crossbar 541 and extends downward along the pipe of the support tube 53. The spring is compressed and sleeved on the center rod 543 to provide an upward elastic force for the crossbar 541. For example, the two ends of the spring are connected to the pipe wall of the support tube 53 and the crossbar 541 respectively. The spring maintains the top end of the crossbar 541 elastically pressed against the top end of the axial groove; thereby making the top end of the plug rod 542 protrude from the top surface of the support tube 53. When the rotor is installed on the top surface of the support tube 53, the rotor presses against the top of the plug rod 542, and the top of the plug rod 542 is pushed back into the slide groove 531. Then the rotor rotates on the top surface of the support tube 53 until the alignment hole on the bottom surface of the rotor is aligned with the plug rod 542. Then the top of the plug rod 542 will slide into the alignment hole on the bottom surface of the rotor, thus achieving accurate positioning of the rotor when it is installed on the top surface of the support tube 53.

[0035] Understandably, a sensor (not shown in the figure) is further provided at the bottom end of the center rod 543 to provide feedback on whether the plug rod 542 is inserted into the alignment hole of the rotor. Understandably, the sensor is fixed to the periphery of the bottom end of the center rod 543. By setting multiple sensors at different heights to detect the position of the center rod 543, it is possible to determine whether the plug rod 542 extends out of the top end of the support tube 53 and is inserted into the alignment hole of the rotor accordingly.

[0036] The support tube 53 is driven to rotate by the drive motor 52, which in turn drives the rotor it carries to rotate. Furthermore, an encoder can be installed at the bottom of the support tube 53 to record the rotation angle and number of rotations of the support tube 53.

[0037] The magnetizing mechanism 40 includes a lower end face magnetizing structure 41 and an upper end face magnetizing structure 42. The lower end face magnetizing structure 41 is used to magnetize the lower end face of the rotor, and the upper end face magnetizing structure 42 is used to magnetize the upper end face of the rotor.

[0038] The lower end face magnetization structure 41 is installed on the platform 211 and can be lifted and detached around the support tube 53. The lower end face magnetization structure 41 includes a lifting cylinder 411, a magnetic plate 412 and a lower filling disk 413. The lifting cylinder 411 is fixed on the bottom surface of the platform 211. The magnetic plate 412 is lifted and detached above the platform 211. The lower filling disk 413 is fixed on the top surface of the magnetic plate 412. The magnetic plate 412 and the lower filling disk 413 are both provided with through holes and are connected to each other for being fitted onto the support tube 53. The output shaft of the lifting cylinder 411 passes through the platform 211 and is connected to the magnetic plate 412, thereby driving the magnetic plate 412 and the lower filling disk 413 to rise and fall. When the lower end face of the rotor is magnetized, the lifting cylinder 411 pushes the magnetic plate 413 upward, so that the upper surface of the lower magnetizing disk 413 is flush with the top surface of the support tube 53. This allows the surface of the lower magnetizing disk 413 to be adjacent to the lower end face of the rotor, thus magnetizing the lower end face of the rotor. Furthermore, pins 414 are evenly spaced along the circumference of the lower magnetizing disk 413, forming a contour corresponding to the outer circumference of the rotor. These pins protect the rotor's outer circumference, limiting radial movement and providing protection. They also determine the distance between the upper and lower magnetizing disks. Preferably, the height of the pins 414 is approximately equal to the thickness of the rotor.

[0039] Please see Figure 7The upper end magnetizing structure 42 is installed in conjunction with the side frame 221 and the top beam 222 on the opposite side of the transfer mechanism 30. It includes a pressing cylinder 421, a lifting frame 422, a magnetizing module 423, and a demolding rod 424. The pressing cylinder 421 is fixedly installed on the top beam 222, and its piston end is connected downwards to the lifting frame 422 to provide driving force for the lifting of the lifting frame 422. The lifting frame 422 is connected to the side frame 221 via a slide rail, which guides and improves the stability of the lifting of the lifting frame 422. The lifting frame 422 includes a horizontally arranged lifting plate 4221 and a side plate 4222 vertically arranged on one side of the lifting plate 4221. The lifting plate 4221 is connected to the piston end of the pressing cylinder 421, and the magnetizing module 423 is installed on the lifting plate 4221. The side plate 4222 cooperates with the side frame 221 via a slide rail. The magnetization module 423 includes a mounting plate 4231, a guide rod 4232, a lifting drive component 4233, and a charging disk 4234. The mounting plate 4231 is arranged parallel to the bottom of the lifting plate 4221. The guide rod 4232 is fixedly arranged at the four corners of the top surface of the mounting plate 4231 and can be lifted and lowered through the lifting plate 4221. The lifting drive component 4233 is fixed on the lifting plate 4221 and is preferably a cylinder. Its piston rod passes downward through the lifting plate 4221 and connects with the mounting plate 4231, thereby driving the mounting plate 4231 to rise and fall relative to the lifting plate 4221. The charging disk 4234 is fixedly installed on the bottom surface of the mounting plate 4231. The lifting drive component 4233 drives the mounting plate 4231 to rise and fall, thereby driving the charging disk 4234 to rise and fall synchronously. Both the lifting plate 4231 and the upper filling disk 4234 have through holes in their centers to allow the demolding rod 424 to pass through.

[0040] The demolding rod 424 is fixedly installed on the bottom surface of the lifting plate 4221 and passes through the through hole in the center of the hoisting plate 4231 and the charging disk 4234. After the upper end face of the rotor is magnetized, the lifting drive component 4233 drives the upper charging disk 4234 to move upward. The demolding rod 424 abuts against the rotor, so that the rotor cannot move upward with the upper charging disk 4234, thus separating the rotor from the upper charging disk 4234. Otherwise, the upper end face of the rotor will be magnetic after being magnetized and will be attracted to the upper charging disk 4234, making it difficult to separate. Specifically, one end of the demolding rod 424 is fixed to the lifting plate 4221, and the other end extends downward and inserts into the through hole of the upper charging disk 4232. When magnetizing the upper surface of the rotor, the end face of the demolding rod 424 is flush with the surface of the upper charging disk 4234 after it has moved down, thus magnetizing the rotor. In this embodiment, the downward movement of the upper charging disk 4234 can be limited by the pin 414 on the lower charging disk 413, that is, the downward movement stops when it abuts against the pin 414, and the upper charging disk 4234 is started to magnetize. It can also be understood that the lower charging disk 413 can be limited by abutting against the upper surface of the rotor. After the upper surface of the rotor is magnetized, the lifting drive 4233 drives the lifting plate 4231 to move upward, and the demolding rod 424 abuts against the rotor, the upper charging disk 4234 disengages from the upper surface of the rotor, and the rotor is still fixed on the support tube 53.

[0041] When the magnetizing mechanism 40 magnetizes the upper and lower end faces of the rotor, after the rotor is positioned on the support tube 53, the lifting cylinder 411 pushes the magnetic plate 412 upward, lifting the lower magnetizing disk 413 to move upward simultaneously, so that the lower magnetizing disk 413 is close to the lower end face of the rotor. At the same time, the pressing cylinder 421 drives the lifting frame 422 downward, the demolding rod 424 first presses against the upper end face of the rotor, and then the lifting drive component 4233 pushes the upper magnetizing disk 4234 close to the rotor, starting the lower magnetizing disk 413 and the upper magnetizing disk 4234 to magnetize both end faces of the rotor. Among them, when the upper magnetizing disk 4234 is close to the rotor, the upper magnetizing disk 4234 stops moving downward when the pin 414 of the lower magnetizing disk 413 abuts against the upper magnetizing disk 4234.

[0042] The surface magnetic detection mechanism 60 is located around the magnetization mechanism 40 and is used to perform surface magnetic detection on the magnetized end face of the rotor. For example, to detect the magnetization integrity and magnetization intensity of the rotor end face, please refer to [link to relevant documentation]. Figure 8The magnetic detection mechanism 60 includes a column 61, a transverse slide 62, a smooth folding arm 63, a longitudinal slide 64, a lifting arm 65, and two detection bodies 66. The column 61 is fixedly erected on the top surface of the base 21 of the machine base 20. The transverse slide 62 is vertically fixed to the top of the column 61 and parallel to the tangent of the support tube 53. The transverse slide 62 can be fastened to the column 61 with a fastening sleeve. When it is necessary to adjust the height of the transverse slide 62, the fastening sleeve can be loosened to adjust the height and then tightened again. The smooth folding arm 63 is installed on the transverse slide 62 and is driven to move by the transverse slide 62. The smooth folding arm 63 is an L-shaped arm, including a longitudinal arm portion and a vertical connecting arm. A transverse extension arm is attached to the bottom of the longitudinal extension arm. The upper end of the longitudinal extension arm is mounted on a transverse slide 62. A longitudinal slide 64 is fixedly mounted on the longitudinal extension arm and extends longitudinally. A lifting arm 65 is mounted on the longitudinal slide 64 and is driven to rise and fall by the longitudinal slide 64. In this embodiment, the lifting arm 65 is a long strip block. Of the two detection bodies 66, one is mounted on the transverse extension arm of the smooth folding arm 63 with the detection port facing upward, and the other detection body 66 is mounted on the lifting arm 65 with the detection port facing downward. Preferably, the two detection bodies 66 are arranged opposite each other in the vertical direction. The lifting arm 65 is driven to rise and fall by the longitudinal slide 64 to adjust the distance between the two detection bodies 66.

[0043] Furthermore, the detection body 66 includes a detection base 661, a gaussmeter 662, and a ball assembly 663. The gaussmeter 662 is fixedly mounted on the surface of the detection base 661. The ball assembly 663 is arranged opposite to each other on both sides of the gaussmeter 662. The ball assembly 663 includes a receiving seat and balls contained within the receiving seat. The upper end of the ball protrudes from the top surface of the receiving seat, forming an exposed rolling surface. The exposed rolling surface is higher than the surface of the gaussmeter 662, so as to avoid friction between the gaussmeter 662 and the rotor surface when the ball assembly 663 rolls against the rotor end face, which would cause damage or affect the surface magnetic detection of the rotor end face by the gaussmeter 662.

[0044] When the magnetic detection mechanism 60 detects the rotor end face, the transverse slide 62 drives the smooth folding arm 63 to slide. The detection body 66 on the transverse extension of the smooth folding arm 63 moves to the lower end face of the rotor and abuts against it. Understandably, since the rotor is fixedly supported on the support mechanism 50, its height is fixed, i.e., the height of the rotor bottom surface is fixed. Therefore, as long as the transverse slide 62 is set to an appropriate height, by moving the smooth folding arm 63, the detection body 66 on the transverse extension will correspondingly abut against the lower end face of the rotor, adapting to the detection distance of the rotor's lower end face. For the upper end face of the rotor, the height may vary depending on the rotor. Therefore, by adjusting the lifting arm 65, the detection body 66 on the lifting arm 65 abuts against the upper end face of the rotor, and the ball bearing assembly 663 of the detection body 66 will abut against the upper end face of the rotor and can roll.

[0045] Then, the drive motor 52 is started, driving the rotor to rotate. The gaussmeters 662 of the two detection bodies 66 detect the surface magnetic properties of the upper and lower end faces of the rotor respectively. After the rotor rotates one revolution, the detection of one ring surface on the rotor end face is completed. The transverse slide 62 drives the smooth folding arm 63 to slide to the next point on the rotor diameter. Similarly, after the rotor rotates one revolution, the detection of the ring surface corresponding to the rotor at the next point is completed. In this way, the points at different diameters are detected step by step until the entire end face of the rotor is completely detected (except for the rotor center position, i.e., the support position corresponding to the support tube 53, which is also not magnetized as a support point). After the detection is completed, the longitudinal slide 64 rises and the transverse slide 62 returns to its original position, and the rotor is ready for removal, which can be removed by the transfer mechanism 30.

[0046] During the processing of the rotor magnetization processing line of the present invention: First, the rotor is placed on the transfer plate 12 of the conveyor line 1. The transfer plate 12 moves along the conveyor frame 11 to the limiting lifting mechanism 13. Then, the lifting pallet unit 132 rises to the preset position against the transfer plate 12. Then, the lifting module 33 of the transfer mechanism 30 descends and clamps the rotor through the clamping module 34. The lifting module 33 drives the rotor to rise. Then, the translation module 32 drives the lifting module 33 to move above the support mechanism 50. Subsequently, the lifting module 33 drives the rotor to descend and holds the rotor against the top surface of the support tube 53. The drive motor 52 drives the support tube 53 to rotate, which in turn drives the positioning component 54 to rotate relative to the rotor, so that the plug rod 542 is inserted into the alignment hole of the rotor for positioning. Then, the clamping arm 342 of the clamping module 34 opens, placing the rotor completely on the support tube 53. Then, the lifting cylinder 411 of the lower magnet 41 pushes the lower magnet disk 413 to rise and approach the lower surface of the rotor. At the same time, the lifting frame 422 of the upper magnet 42 descends, causing the upper magnet disk 4234 to abut against the upper surface of the rotor. The rotor is magnetized by the lower magnet disk 413 and the upper magnet disk 4234. After magnetization is completed, the lower magnetization disk 413 and the upper magnetization disk 4234 are reset, and the lifting frame 422 rises. Then, the transverse slide 62 of the surface magnetization detection mechanism 60 drives the smooth folding arm 63 to approach the rotor, so that the detection body 66 installed on the smooth folding arm 63 abuts against the lower surface of the rotor. The longitudinal slide 64 drives the connected detection body 66 to abut against the upper surface of the rotor. In this way, the two detection bodies 66 simultaneously detect the surface magnetization intensity of the upper and lower end surfaces of the rotor. The rotor is driven to rotate through the support tube 53, and the two detection bodies 66 perform corresponding annular surface detection on the rotor. The smooth folding arm 63 is translated, and the two detection bodies 66 perform multi-point detection on the rotor step by step until the detection of the upper and lower end surfaces of the entire rotor is completed. Finally, the surface magnetization detection mechanism 60 is reset, the transfer mechanism 30 removes the rotor and places it on the transfer plate 12 for transfer and collection, completing the automatic magnetization process of the rotor.

[0047] In summary, the rotor magnetization processing line provided by the present invention transports the rotor to the front of the magnetization device 2 via the conveyor line 1, the transfer mechanism 30 clamps the rotor and places it on the support mechanism 50 for positioning, the magnetization mechanism 40 magnetizes the upper and lower end faces of the rotor, and then the surface magnetic strength is detected by the surface magnetic strength detection mechanism 60, thereby realizing automatic magnetization and detection of both end faces of the rotor, which greatly improves production efficiency.

It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this patent should be determined by the appended claims.
