Description

Technical Field

[0001] This application belongs to the field of motor manufacturing, and more specifically, relates to a rotor magnetizing and shaft inserting device. Background Art

[0002] The motor rotor is a rotating component in the motor, which is a device for realizing the conversion between electrical energy and mechanical energy, and between mechanical energy and electrical energy. The rotor generally includes a rotating shaft and a core assembly. The core assembly generally includes a rotor core and a permanent magnet. The rotor core is provided with magnet slots, and the permanent magnets are installed in the magnet slots. After the permanent magnets are installed in the magnet slots, it is necessary to magnetize the core assembly so that the permanent magnets have magnetism. A central shaft hole is provided at the central axis of the rotor core, and the rotating shaft is inserted into the central shaft hole of the core assembly.

[0003] Some motor rotors include a rotating shaft and multiple core assemblies. The multiple core assemblies are sequentially sleeved on the rotating shaft along the axial direction of the rotating shaft, thereby improving the power density. When two or more core assemblies are assembled onto the rotating shaft at the same angle, the torque ripple of the motor rotor is relatively large. However, the existing rotor magnetizing and shaft inserting devices cannot achieve the angularly staggered assembly of two or more core assemblies. Summary of the Invention

[0004] The purpose of the embodiments of this application is to provide a rotor magnetizing and shaft inserting device to solve the technical problem in the related art that the rotor magnetizing and shaft inserting device cannot achieve the angularly staggered assembly of two or more core assemblies.

[0005] To achieve the above purpose, the technical solution adopted in the embodiments of this application is: Provide a rotor magnetizing and shaft inserting device, including: A magnetizing mechanism for magnetizing the core assembly; A shaft inserting mechanism, including a first sliding assembly and a pressing shaft assembly. The first sliding assembly includes a first working plate, a first sliding driving member, and a first slide rail extending along a first direction. The first working plate has two or more first positioning through holes spaced apart along the first direction. A first positioning pin is provided at the peripheral edge of the top of the first positioning through hole. The first positioning pins of the first positioning through holes distributed along the first direction are sequentially deflected in a preset direction. The first sliding driving member is used to drive the first working plate to slide along the first slide rail; The pressing shaft assembly includes a pressing shaft driving member and a clamping assembly. The clamping assembly includes a pressing shaft member and a clamping sleeve arranged coaxially. The pressing shaft member is used to position and abut against the top end of the rotating shaft. The clamping sleeve is used to clamp the core assembly. The pressing shaft driving member is located above the first working plate. The pressing shaft driving member is connected to the clamping assembly. The pressing shaft driving member is used to drive the clamping assembly to perform a lifting motion.

[0006] The rotor magnetizing and shaft - inserting device provided by the embodiment of the present application has at least the following beneficial effects: The magnetizing mechanism magnetizes a plurality of iron - core components. After the magnetization of the plurality of iron - core components is completed, they are transported to the first working plate manually or by a transfer manipulator and are respectively positioned and placed in a plurality of first positioning through - holes through the first positioning pins. Since the first positioning pins of the first positioning through - holes distributed along the first direction are sequentially deflected in a preset direction, the placement angles of the plurality of iron - core components are sequentially deflected and staggered. The plurality of iron - core components with staggered angles slide sequentially along the first direction to the lower part of the clamping component. The clamping component makes a lifting motion under the drive of the shaft - pressing driving part, and the clamping rotating shaft sequentially presses the plurality of iron - core components, realizing the stacked socket connection of the plurality of iron - core components with staggered angles to the rotating shaft. Furthermore, the tooth harmonics generated by each iron - core component cancel or weaken each other, reducing the torque ripple and reducing the vibration and noise of the motor rotor.

[0015] References to "one embodiment" or "an embodiment" in the course of the specification mean that a particular feature, structure, or characteristic described in connection with the embodiment is included in at least one embodiment of the present application. Thus, the phrases "in one embodiment" or "in some embodiments" appearing in various places throughout the specification do not necessarily all refer to the same embodiment. Moreover, the particular features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.

[0016] The rotor magnetizing and shaft inserting device provided by the embodiments of the present application will now be described. Please refer to Figure 1 , Figure 2 and Figure 3 . The first direction X, the second direction Y, and the vertical direction Z are perpendicular to each other pairwise. The rotor magnetizing and shaft inserting device includes a magnetizing mechanism 10 and a shaft inserting mechanism 20. The magnetizing mechanism 10 is used to magnetize the iron core assembly 2.

[0017] Please refer to Figure 4 . The shaft inserting mechanism 20 includes a first sliding assembly 100 and a pressing shaft assembly 200. The first sliding assembly 100 includes a first working plate 110, a first sliding driving member 120, and a first slide rail 130 extending along the first direction X. The first working plate 110 has two or more first positioning through holes 111 spaced along the first direction X. A first positioning pin 112 is provided on the peripheral edge of the top of the first positioning through hole 111. The first positioning pins 112 of the first positioning through holes 111 distributed along the first direction X are sequentially deflected in a preset direction. The first sliding driving member 120 is used to drive the first working plate 110 to slide along the first slide rail 130.

[0018] Please refer to Figure 3 and Figure 5 . The pressing shaft assembly 200 includes a pressing shaft driving member 210 and a clamping assembly 220. The clamping assembly 220 includes a pressing shaft member 221 and a clamping sleeve 222 arranged coaxially. The pressing shaft member 221 is used to position and abut against the top end of the rotating shaft 1. The clamping sleeve 222 is used to clamp the iron core assembly 2. The pressing shaft driving member 210 is located above the first working plate 110. The pressing shaft driving member 210 is connected to the clamping assembly 220. The pressing shaft driving member 210 is used to drive the clamping assembly 220 to perform a lifting motion.

[0019] Among them, the magnetizing mechanism 10 magnetizes the multiple core assemblies 2. After the magnetization of the multiple core assemblies 2 is completed, they are transported to the first working plate 110 by manual or transfer manipulators, and are positioned and placed in the multiple first positioning through holes 111 respectively through the first positioning pins 112. Since the first positioning pins 112 of the first positioning through holes 111 distributed along the first direction X are deflected and set in sequence according to the preset direction, the placement angles of the multiple core assemblies 2 are deflected and staggered in sequence. The multiple core assemblies 2 with staggered angles slide to the bottom of the clamping assembly 220 in sequence along the first direction X. The clamping assembly 220 performs lifting and lowering motion under the drive of the pressing shaft driving member 210, and the clamping shaft 1 is pressed and connected with the multiple core assemblies 2 in sequence, so that the multiple core assemblies 2 are stacked and sleeved on the shaft 1 with staggered angles, and then the tooth harmonics generated by each core assembly 2 offset or weaken each other, reduce torque pulsation, and reduce motor rotor vibration and noise.

[0020] It should be noted that the rotor magnetizing shaft device provided in this embodiment realizes the staggered placement angle of the core assembly 2 through the first positioning pin 112, without the need for additional precision electronic control components such as rotating motors and encoders, and only requires setting first positioning pins 112 of different angles on different first positioning through holes 111. On the one hand, the manufacturing cost is greatly reduced; on the other hand, compared with the electronic control method, the mechanical method is easy to implement and has reliable accuracy.

[0021] Combination Figure 4 Each first positioning through hole 111 is configured with two first positioning pins 112, and the two first positioning pins 112 are located in the same radial direction of the first positioning through hole 111. Looking from left to right, the angle between the line connecting the first group of first positioning pins 112 and the first direction X is 0. Assuming that the angle between the line connecting the second group of first positioning pins 112 and the first direction X is θ, the angle between the line connecting the third group of first positioning pins 112 and the first direction X is 2θ, that is, in the multiple first positioning through holes 111 distributed along the first direction X, the setting angles of the first positioning pins 112 are deflected by angle θ in sequence.

[0022] When the motor is running, the tooth harmonics generated by the interaction between the stator tooth slots and the core assembly 2 are the main source of torque pulsation. When the assembly angles of the core assemblies 2 are deflected in sequence according to the deflection angle θ, the magnetic fields of adjacent core assemblies 2 form a phase difference in space, so that the tooth harmonics weaken each other when superimposed. In addition, the angle deflection causes the magnetic fields of the core assemblies 2 to form a step-by-step dislocation in the axial direction, and the superimposed air gap magnetic flux waveform is closer to a sine wave, reducing the high-order harmonic components.

[0023] Generally, the deflection angle θ is 3° to 8°. For the low-speed high-torque scenario, the deflection angle θ can be selected as 6° to 8° to enhance the suppression of low-order harmonics (such as the 6th and 12th harmonics); for the high-speed low-torque scenario, the deflection angle θ can be selected as 3° to 5° to reduce high-frequency losses and improve high-speed stability. Taking a 4-pole 24-slot motor as an example, when the deflection angle θ is 5°, the phase difference of the 24th tooth harmonic is 5° × 24 = 120°, and the amplitude decays to cos120° = 0.5 of the original amplitude; after superimposing 3 core components 2 (phase differences of 0°, 120°, and 240°), the harmonic amplitude can theoretically be reduced to 0.

[0024] Optionally, the deflection angle θ is 3°, 4°, 5°, 6°, 7°, and 8°.

[0025] In one embodiment, in combination with Figure 1 , the rotor magnetization and shaft insertion device further includes a controller 30, and the controller 30 is electrically connected to the magnetization mechanism 10 and the shaft insertion mechanism 20 respectively, to improve the automation level, control the production rhythm, and carry out the magnetization and shaft insertion processes in an orderly manner. For example, the controller 30 is electrically connected to the first sliding drive member 120 and the shaft pressing drive member 210 respectively.

[0026] In one embodiment, please refer to Figure 3 , Figure 6 and Figure 7 , as a specific implementation manner of the rotor magnetization and shaft insertion device provided in the embodiment of the present application, the shaft pressing drive member 210 is connected to the clamping assembly 220 through a first lifting shaft 211. A pressing plate 212 is connected to the end of the first lifting shaft 211. The pressing plate 212 has a large area, which is convenient for the pressing plate 212 to be connected to the shaft pressing member 221 and the clamping sleeve 222 respectively, and is convenient for the uniform distribution of force.

[0027] In one embodiment, please refer to Figure 3 and Figure 4 , a force sensor 230 is provided between the end of the first lifting shaft 211 and the pressing plate 212. The force sensor 230 is used to detect the pressure borne by the end of the first lifting shaft 211. When multiple core components 2 are assembled in a staggered manner in sequence, the shaft pressing drive member 210 drives the pressing plate 212 to descend until the pressure of the pressing plate 212 reaches a preset value, and the pressing plate 212 stops descending further, so that the pressing force of the rotating shaft 1 on each core component 2 is the same, to avoid axial offset or angular deviation caused by uneven force and achieve assembly consistency.

[0028] In one embodiment, please refer to Figure 4 and Figure 6, the pressing assembly 200 further includes a displacement sensor 240. The displacement sensor 240 is installed on the pressing plate 212 and moves up and down with the pressing plate 212 to detect the lifting displacement of the clamping sleeve 222. When multiple iron core assemblies 2 are assembled with staggered levels in sequence, the pressing drive 210 drives the pressing plate 212 to descend. Through the displacement sensor 240, the depth of the rotating shaft 1 extending into the iron core assembly 2 can be identified, and the pressing depth can be accurately controlled to ensure the axial positioning accuracy of the iron core assembly 2 and avoid excessive gaps or mutual interference between two adjacent iron core assemblies 2.

[0029] When manufacturing motor rotors of different models, the thickness or quantity of the iron core assemblies 2 may be different. The displacement sensor 240 provides real-time feedback on the current pressing position, and the controller 30 automatically adjusts the stroke of the pressing drive 210 to adapt to the assembly requirements of different specifications without manual re-setting of mechanical limits.

[0030] Specifically, the controller 30 is electrically connected to the displacement sensor 240 and the force sensor 230 respectively to obtain a force-displacement curve and determine whether the iron core assembly 2 is in place completely, so as to avoid assembly defects caused by mechanical limit errors.

[0031] In one embodiment, please refer to Figure 6 and Figure 7 , as a specific implementation manner of the rotor magnetization and shaft insertion device provided by the embodiment of the present application, the pressing assembly 200 further includes a pressing guide rod 251, a first adapter 252, a second adapter 257, a first elastic member 253 and a first limit sleeve 254. The first adapter 252 is installed at the end of the first lifting shaft 211. The second adapter 257 has a linkage rising hole 258 for sleeving the first adapter 252. There is a step in the linkage rising hole 258 for pressing against the first adapter 252. Thus, the second adapter 257 rises with the first adapter 252 and can be separated from the first adapter 252 when the first adapter 252 descends. The second adapter 257 has a pressing guide hole 255. One end of the pressing guide rod 251 is fixedly installed on the pressing plate 212, and the other end of the pressing guide rod 251 passes through the pressing guide hole 255 and is fixedly sleeved on the first limit sleeve 254. Two ends of the first elastic member 253 respectively abut against the first limit sleeve 254 and the second adapter 257.

[0032] When the first lifting shaft 211 rises, the first adapter 252 rises, driving the second adapter 257 that is pressed against the upper side of the first adapter 252 through the step to rise. The second adapter 257 compresses the first elastic member 253 when it rises, and then drives the pressing plate 212 to rise accordingly. When the first lifting shaft 211 descends, the first adapter 252 separates from the step of the linkage rising hole 258, and the gravity and the elastic force of the first elastic member 253 press the step of the linkage rising hole 258 onto the first adapter 252 to maintain the pressing state. At the same time, the first adapter 252 descends to press the force sensor 230 or the pressing plate 212, driving the pressing plate 212 to descend.

[0033] Based on this, when the first lifting shaft 211 descends, the pressing plate 212 does not descend immediately. The first elastic member 253 absorbs the impact kinetic energy, converts the instantaneous peak force into a controllable gradual force, and prevents the iron core assembly 2 from cracking or warping due to the impact force. When the first lifting shaft 211 rises, the first adapter 252 drives the second adapter 257 to rise, compresses the first elastic member 253, and then drives the pressing plate 212 to rise through the first limiting sleeve 254, converting the instantaneous peak force into a controllable gradual force.

[0034] When there are dimensional tolerances in different iron core assemblies 2 or rotating shafts 1, the first elastic member 253 can adjust the pressure through the compression amount to ensure uniform force when each iron core assembly 2 is press-fitted, avoiding assembly stress concentration caused by rigid contact. For example, it can prevent the iron core assembly 2 from warping or deforming after press-fitting, and there is no need to separately adjust the press-fitting parameters for the minor tolerances of each iron core assembly 2.

[0035] Optionally, the force sensor 230 is located between the pressing plate 212 and the first adapter 252 and is mounted on the pressing plate 212. When the first lifting shaft 211 rises, the first adapter 252 drives the second adapter 257 to rise through the pressing relationship, and there is no relative acting force between the first adapter 252, the second adapter 257 and the force sensor 230. When the first lifting shaft 211 descends, the first adapter 252 descends to directly press the force sensor 230 to achieve accurate measurement of the press-fitting force.

[0036] Specifically, when the first elastic member 253 abuts against the first adapter 252, it can abut against the upper end surface of the shaft pressing guide hole 255 or inside the shaft pressing guide hole 255, and this is not uniquely limited here. Specifically, the first limiting sleeve 254 is threadedly sleeved on the shaft pressing guide rod 251.

[0037] In one embodiment, please refer to Figure 5 and Figure 6, as a specific implementation of the rotor magnetizing and shaft - inserting device provided in the embodiments of the present application, the pressing shaft member 221 is connected to the pressing plate 212 through the second elastic member 256. When the multi - core assemblies 2 are stacked and pressed, the angular offset of each core assembly 2 may cause the pressing angle of the rotating shaft 1 to shift or the axial position of the rotating shaft 1 to deviate. The second elastic member 256 enables the rotating shaft 1 to adaptively compensate for the pressing angle or the axial installation position through its own deformation. Among them, the clamping sleeve 222 is rigidly connected to the pressing plate 212, ensuring that the clamping sleeve 222 and the core assembly 2 it clamps do not adaptively compensate for the position deviation, guaranteeing that the installation angle of the core assembly 2 is assembled according to the preset deflection angle, and avoiding the shaking of the installation angle of the core assembly 2.

[0038] In one embodiment, please refer to Figure 3 and Figure 6 , the shaft - inserting mechanism 20 further includes a shaft - inserting bracket 21, and the pressing shaft driving member 210, the first slide rail 130, and the first sliding driving member 120 are respectively installed on the shaft - inserting bracket 21. Specifically, the shaft - inserting bracket 21 includes a first top plate 24, a first bottom plate 23, and a first connecting column 25. The first top plate 24 and the first bottom plate 23 are arranged at intervals up and down, and a plurality of first connecting columns 25 are connected between the first top plate 24 and the first bottom plate 23. The plurality of first connecting columns 25 are circumferentially spaced along the first top plate 24. The shaft - inserting mechanism 20 further includes a pressing shaft bracket 260, and the pressing shaft bracket 260 is slidably connected between the pressing plate 212 and the first top plate 24 along the vertical direction Z.

[0039] In one embodiment, please refer to Figure 5 and Figure 6 , as a specific implementation of the rotor magnetizing and shaft - inserting device provided in the embodiments of the present application, the clamping assembly 220 further includes a pair of shaft - clamping driving members 223. The clamping sleeve 222 has a pair of shaft - clamping holes 224 that penetrate along the same radial direction. The pair of shaft - clamping driving members 223 are respectively installed on the outer wall of the clamping sleeve 222. The output shafts of the pair of shaft - clamping driving members 223 respectively clamp the opposite sides of the same radial direction of the rotating shaft 1 through the shaft - clamping holes 224, ensuring that the rotating shaft 1 does not rotate after being stably installed. The pair of shaft - clamping driving members 223 clamp the rotating shaft 1 bidirectionally, avoiding axial offset or radial inclination caused by unilateral force.

[0040] In one embodiment, please refer to Figure 5 , the clamping assembly 220 further includes a positioning disk 225. The positioning disk 225 is fixedly installed on the clamping sleeve 222. The positioning disk 225 protrudes with an assembly positioning pin 226. The installation radial direction of the assembly positioning pin 226 on the positioning disk 225 is the same as the installation angle of the first core assembly 2 assembled with the rotating shaft 1, thereby guiding the first assembled core assembly 2 to be transferred from the first working plate 110 to the clamping sleeve 222 without changing the angle.

[0041] In one embodiment, please refer toFigure 6 As a specific implementation of the rotor magnetizing and shaft inserting device provided in the embodiments of the present application, the shaft inserting mechanism 20 further includes a shaft jacking assembly 300. The shaft jacking assembly 300 includes a shaft jacking member 310 and a shaft jacking driving member 320. The shaft jacking member 310 is used to position and abut against the bottom end of the rotating shaft 1. The shaft jacking member 310 is coaxially arranged with the shaft pressing member 221. The outer diameter of the shaft jacking member 310 is smaller than the aperture of the first positioning through hole 111. The shaft jacking driving member 320 is installed below the first working plate 110, and the shaft jacking driving member 320 is used to drive the shaft jacking member 310 to perform lifting and lowering movements. The shaft jacking member 310 and the shaft pressing member 221 jointly support the rotating shaft 1 to perform lifting and lowering movements up and down, ensuring the accurate and reliable axial movement of the rotating shaft 1. When it is necessary to jack up the rotating shaft 1, both the shaft jacking member 310 and the shaft pressing member 221 press the rotating shaft 1, and the pressing force of the shaft jacking member 310 is greater than the pressing force of the shaft pressing member 221, and the rotating shaft 1 rises. When it is necessary for the rotating shaft 1 to descend, both the shaft jacking member 310 and the shaft pressing member 221 press the rotating shaft 1, and the pressing force of the shaft jacking member 310 is less than the pressing force of the shaft pressing member 221, and the rotating shaft 1 descends.

[0042] Optionally, both the shaft jacking member 310 and the shaft pressing member 221 are embedded in the positioning holes at both ends of the rotating shaft 1 to achieve stable support.

[0043] Specifically, the shaft jacking member 310 and the shaft pressing member 221 are respectively connected to an external cold source. The shaft jacking member 310 and the shaft pressing member 221 make the temperature of the rotating shaft 1 drop by contacting the rotating shaft 1, thereby facilitating the temporary reduction of the outer diameter of the rotating shaft 1 and smoothly inserting it into the iron core assembly 2. After assembly, the rotating shaft 1 is separated from the shaft jacking member 310 and the shaft pressing member 221, and expands back to the initial outer diameter at room temperature, firmly stuck in the iron core assembly 2, improving the assembly firmness between the rotating shaft 1 and the iron core assembly 2.

[0044] In one embodiment, please refer to Figure 3 and Figure 6 As a specific implementation of the rotor magnetizing and shaft inserting device provided in the embodiments of the present application, the shaft inserting mechanism 20 further includes a first position sensor 410. The detection direction of the first position sensor 410 is perpendicular to the vertical direction Z. The detection height of the first position sensor 410 is higher than the first positioning through hole 111. The first position sensor 410 is used to detect whether the clamping assembly 220 clamps the rotating shaft 1. If the rotating shaft 1 is detected to exist, the first sliding assembly 100 sequentially transports the iron core assembly 2 to directly below the shaft pressing assembly 200.

[0045] In one embodiment, please refer to Figure 2 and Figure 3, as a specific implementation of the rotor magnetizing and shaft inserting device provided by the embodiments of the present application, the shaft inserting mechanism 20 further includes a second position sensor 420 located upstream of the shaft pressing assembly 200. The number of the second position sensors 420 is the same as the number of the first positioning through holes 111. All the second position sensors 420 are spaced along the first direction X and have the same interval as that between all the first positioning through holes 111. The second position sensor 420 is used to detect whether the iron core assembly 2 is placed in the first positioning through hole 111. All the second position sensors 420 synchronously detect whether all the iron core assemblies 2 to be assembled on a rotating shaft 1 are in place. If it is detected that a certain first positioning through hole 111 has no iron core assembly 2, the controller 30 immediately suspends the subsequent clamping and shaft pressing actions to prevent empty pressing.

[0046] In one embodiment, please refer to Figure 4 , as a specific implementation of the rotor magnetizing and shaft inserting device provided by the embodiments of the present application, the first working plate 110 includes a first plate member 113 and a second plate member 114 which are spaced up and down. The first plate member 113 is located below the second plate member 114. The first plate member 113 is connected to the first sliding driving member 120. The second plate member 114 is provided with a first positioning pin 112. Both the first plate member 113 and the second plate member 114 have a through first positioning through hole 111. A third elastic member (not shown in the figure) is provided between the first plate member 113 and the second plate member 114. When the shaft pressing assembly 200 presses the rotating shaft 1 onto the iron core assembly 2 located on the second plate member 114, the third elastic member bears the axial impact force during pressing, and the elastic buffer force prevents the iron core assembly 2 from deforming due to local stress concentration. When there is an angular deviation between the rotating shaft 1 clamped by the clamping assembly 220 and the iron core assembly 2, the deformation buffer of the third elastic member can flexibly guide the insertion of the rotating shaft 1 to avoid jamming.

[0047] In one embodiment, in combination with Figure 4 , a heating body (not shown in the figure) is provided on the periphery of the first positioning through hole 111. The heating body realizes heat transfer by abutting against the iron core assembly 2, which is beneficial to expanding the inner diameter of the iron core assembly 2 and facilitating the smooth pressing of the rotating shaft 1 and the iron core assembly 2. After returning to room temperature, the inner diameter of the iron core assembly 2 shrinks and is firmly fixed to the rotating shaft 1 by interference fit.

[0048] In one embodiment, in combination with Figure 4 , the first positioning pin 112 is electrically connected to an external resistance measuring circuit. The two first positioning pins 112 of each first positioning through hole 111 measure the resistance of the iron core assembly 2 by embedding the iron core assembly 2, and then judge the quality of the iron core assembly 2.

[0049] Specifically, two first positioning pins 112 obtain the measured resistance R1 of the iron core assembly 2 at the current temperature. The temperature coefficient of resistance describes how the resistance value of the iron core assembly 2 changes with temperature. According to the formula of the Temperature Coefficient of Resistance (TCR), , where TCR represents the temperature coefficient of resistance, R1 represents the resistance value corresponding to the iron core assembly 2 at the actual measured temperature T1, and R0 represents the reference resistance corresponding to the iron core assembly 2 at the experimental temperature T0. The controller 30 obtains the converted resistance R2 corresponding to the experimental temperature T0 based on the measured resistance R1 according to the formula TCR, and determines the resistance deviation value corresponding to the iron core assembly 2 based on the difference between the converted resistance R2 and the reference resistance R0, and then judges the quality of the iron core assembly 2, such as the insulation of the iron core assembly 2, the uniformity of the insulation coating, etc.

[0050] In one embodiment, please refer to Figure 2 , the shaft feeding mechanism 20 further includes a first feeding component 431 and a third position sensor 432. One end of the first feeding component 431 is connected to the magnetizing mechanism 10, and the other end is connected to the first sliding component 100, realizing the transfer of the iron core assembly 2 from the magnetizing mechanism 10 to the shaft feeding mechanism 20. The third position sensor 432 is used to detect whether the first feeding component 431 is placed with the iron core assembly 2. By counting the number of transferred iron core assemblies 2, it is convenient to subsequently transfer the required number of iron core assemblies 2 to the first working plate 110.

[0051] Optionally, the first feeding component 431 transfers the iron core assembly 2 along the first direction X.

[0052] Optionally, the first feeding component 431 is located between the magnetizing mechanism 10 and the pressing shaft component 200, and the three are spaced apart along the second direction Y without interfering with each other.

[0053] In one embodiment, please refer to Figure 2 , the shaft feeding mechanism 20 further includes a second feeding component 441 and a fourth position sensor 442. The second feeding component 441 is used to convey the rotating shaft 1 to the pressing shaft component 200. The fourth position sensor 442 is used to detect whether the second feeding component 441 is placed with the rotating shaft 1.

[0054] Optionally, the second feeding component 441 transfers the iron core assembly 2 along the second direction Y. The second feeding component 441 and the first feeding component 431 are located on both sides of the first sliding component 100 in the second direction Y without interfering with each other.

[0055] Optionally, the second feeding component 441 is further configured to convey the assembled rotor and iron core assembly 2 out. When the second feeding component 441 slides along the second direction Y towards the first working plate 110, the supply shaft 1 is provided. Meanwhile, the assembled rotor and iron core assembly 2 are received and returned along the second direction Y.

[0056] In one embodiment, referring to Figure 2 , the shaft feeding mechanism 20 further includes a fifth position sensor 450, and the fifth position sensor 450 is located at one end of the first sliding component 100 away from the pressing shaft component 200. The fifth position sensor 450 is configured to detect whether the first working plate 110 is located at one end of the first sliding component 100 away from the pressing shaft component 200, facilitating the transfer of the iron core assembly 2 onto the first working plate 110, and ensuring that the transfer and pressing are not interfered with each other.

[0057] In one embodiment, referring to Figure 1 , as a specific implementation manner of the rotor magnetizing and shaft feeding device provided in the embodiments of the present application, the rotor magnetizing and shaft feeding device further includes a transfer manipulator, and the transfer manipulator is configured to transfer the magnetized iron core assembly 2 from the second working plate 510 to the first working plate 110.

[0058] In one embodiment, referring to Figure 8 and Figure 9 , as a specific implementation manner of the rotor magnetizing and shaft feeding device provided in the embodiments of the present application, the magnetizing mechanism 10 includes a second sliding component 500, a magnetizing component 600, and more than two lifting components 700.

[0059] Combining Figure 10 and Figure 11 , the second sliding component 500 includes a second working plate 510, a second sliding driving member 520, and a second slide rail 530. The second working plate 510 has more than two second positioning through holes 511 distributed at intervals in a straight line. The second sliding driving member 520 is configured to drive the second working plate 510 to slide along the second slide rail 530. The magnetizing component 600 includes a magnetizing bracket 610 and a magnetizing head 620. The magnetizing head 620 is installed on the magnetizing bracket 610, and the magnetizing head 620 is located above the second slide rail 530. Each lifting component 700 is installed below a second positioning through hole 511. The lifting component 700 includes a lifting driving member 710, a support seat 720, and a second positioning pin 730. The support seat 720 is movably disposed in the corresponding second positioning through hole 511. The second positioning pin 730 protrudes from the support seat 720, and the second positioning pin 730 is configured to be positioned and embedded in the iron core assembly 2. The lifting driving member 710 is installed on the second working plate 510, and the lifting driving member 710 is configured to drive the support seat 720 to perform a lifting motion, so that the iron core assembly 2 located on the support seat 720 enters the magnetizing head 620.

[0060] Each lifting assembly 700 is installed below a second positioning through hole 511. The lifting assembly 700 includes a lifting driving member 710, a support seat 720, and a second positioning pin 730. The support seat 720 is movably arranged in the corresponding second positioning through hole 511. The second positioning pin 730 protrudes from the support seat 720 and is used for positioning and embedding in the iron core assembly 2 to prevent the iron core assembly 2 from rotating on the support seat 720, so as to guide and limit the placement angle of the iron core assembly 2. The lifting driving member 710 is installed on the second working plate 510 and is used for driving the support seat 720 to move up and down, so that the iron core assembly 2 located on the support seat 720 enters the magnetizing head 620 for magnetization.

[0061] Optionally, since the second positioning pins 730 of different lifting assemblies 700 are sequentially deflected in a preset direction, that is, the deflection angles of all the second positioning pins 730 and all the first positioning pins 112 correspond one by one, the iron core assembly 2 only needs to keep the angle unchanged during the transfer process without adjusting the angle. Of course, the setting angles of the second positioning pins 730 of different lifting assemblies 700 can also be the same. After the iron core assembly 2 is transferred to the first working plate 110, with the guidance of the first positioning pins 112, the angle is sequentially deflected.

[0062] In one embodiment, in combination with Figure 9 、 Figure 10 and Figure 12 , the lifting assembly 700 further includes a coaxial limiting block 740. The coaxial limiting block 740 is installed on the top of the support seat 720, and the outer diameter of the coaxial limiting block 740 matches the inner diameter of the iron core assembly 2. Based on this, the coaxial limiting block 740 makes the iron core assembly 2 placed on the support seat 720 coaxial with it, which is beneficial to force the iron core assembly 2 to coincide with the axis of the rotating shaft 1 during subsequent magnetization. By improving the coaxiality between the iron core assembly 2 and the magnetizing head 620, the air-gap magnetic density distribution is made more uniform. Moreover, the coaxial limiting block 740 realizes the coaxiality constraint of the iron core assembly 2 in a mechanical hard constraint manner, and the scheme is easy to implement and has high reliability.

[0063] In one embodiment, referring to Figure 12 , the number of the second positioning pins 730 of each lifting assembly 700 is more than two and is circumferentially spaced along the coaxial limiting block 740. More than two second positioning pins 730 further improve the positioning effect on the iron core assembly 2. When the constraint of the coaxial limiting block 740 is not considered, more than two second positioning pins 730 can prevent the iron core assembly 2 from shaking.

[0064] Optionally, in each lifting assembly 700, the number of the second positioning pins 730 is two, and the connection line of the two second positioning pins 730 passes through the center of the top view of the support base 720. On the one hand, the coaxiality between the lifting iron core assembly 2 and the lifting assembly 700 is improved; on the other hand, excessive second positioning pins 730 are avoided to cause over-positioning, and thus it is avoided that it is difficult to embed the iron core assembly 2 due to the machining errors of multiple second positioning pins 730.

[0065] In one embodiment, please refer to Figure 12 , the lifting assembly 700 further includes a guiding sleeve 750, the guiding sleeve 750 is installed on the second working plate 510 and is coaxially arranged with the corresponding second positioning through hole 511, and the guiding sleeve 750 is used for movably sleeving the lifting shaft 711 of the lifting driving member 710. The lifting shaft 711 moves in the guiding sleeve 750, forcing the lifting direction to coincide with the vertical direction Z, ensuring that the iron core assembly 2 enters the magnetizing head 620 along the vertical direction Z, and avoiding the axis offset of the iron core assembly 2.

[0066] In one embodiment, in combination with Figure 12 , the inner wall of the guiding sleeve 750 has a first positioning groove 751, the lifting shaft 711 of the lifting driving member 710 has a second positioning groove 712, and the lifting assembly 700 further includes a key plate 760, and the key plate 760 is respectively embedded in the first positioning groove 751 and the second positioning groove 712. The key plate 760 keeps the lifting shaft 711 and the guiding sleeve 750 in a fixed angular relationship through rigid constraint, avoiding the circumferential offset of the lifting shaft 711 due to the torque fluctuation or external force during the start and stop of the lifting driving member 710, preventing the lifting shaft 711 and the iron core assembly 2 from rotating at an angle during the lifting process, and ensuring that the iron core assembly 2 enters the magnetizing head 620 reliably at an angle.

[0067] In one embodiment, in combination with Figure 12 , the lifting shaft 711 of the lifting driving member 710 has a first positioning plane 713, the guiding sleeve 750 has a positioning notch 752, and the positioning notch 752 and the first positioning plane 713 are located in the same radial direction of the lifting shaft 711 of the lifting driving member 710. During installation, through the corresponding relationship between the first positioning plane 713 and the positioning notch 752, the circumferential position of the lifting shaft 711 relative to the guiding sleeve 750 can be quickly determined without additional calibration steps.

[0068] In one embodiment, please refer to Figure 12 , the magnetizing mechanism 10 further includes a lifting mounting frame 801, and all the lifting driving members 710 are installed on the lifting mounting frame 801 at intervals along the first direction X, so that all the lifting driving members 710 are installed on the second working plate 510 based on the same reference, avoiding cumulative errors.

[0069] Specifically, the jacking mounting frame 801 is located below the second working plate 510. The jacking mounting frame 801 is fixedly mounted on the second working plate 510 through multiple mounting columns 802. The multiple mounting columns 802 rigidly connect the jacking mounting frame 801 and the second working plate 510, enabling the load of each jacking driving member 710 to be evenly transmitted to the entire second working plate 510.

[0070] In one embodiment, please refer to Figure 12 , the jacking assembly 700 further includes a buffer 770. The buffer 770 is fixedly mounted on the fixed part of the jacking driving member 710. The output end of the buffer 770 is connected to the jacking shaft 711 of the jacking driving member 710. When the jacking shaft 711 starts or stops, the buffer 770 absorbs kinetic energy through a damping medium (such as hydraulic oil, air), and can attenuate the vibration frequency of the jacking shaft 711, avoiding the angular deviation of the iron core assembly 2 caused by vibration.

[0071] In one embodiment, the buffer 770 and the jacking driving member 710 are arranged side by side to avoid spatial interference with axial components such as the guiding sleeve 750. The directions of the forces output by the two are the same, enabling the buffer 770 to more effectively buffer the jacking shaft 711 in the vertical direction Z.

[0072] Specifically, the output end of the buffer 770 is connected to the jacking shaft 711 through a cross bar 780 to achieve force transmission.

[0073] In one embodiment, each jacking driving member 710 corresponds to two buffers 770. The two buffers 770 are located on opposite sides of the jacking shaft 711 of the jacking driving member 710, using symmetric damping forces to offset the lateral torque borne by the jacking shaft 711 and eliminate the axial yaw that may be generated by a single buffer 770.

[0074] Optionally, the two buffers 770 are located on opposite sides of the jacking shaft 711 in the first direction X.

[0075] In one embodiment, please refer to Figure 9 , the magnetizing mechanism 10 further includes a plurality of sixth position sensors 803 spaced apart along the first direction X. Each second positioning through hole 511 corresponds to a sixth position sensor 803. The sixth position sensor 803 is used to detect whether the iron core assembly 2 is placed in the second positioning through hole 511, and to provide real-time feedback on whether the iron core assembly 2 is in place, avoiding omission of the iron core assembly 2 and improving the assembly accuracy.

[0076] In one embodiment, combining Figure 8 and Figure 9, the magnetizing head 620 is installed on the magnetizing bracket 610 through the magnetizing driving member 630, and the magnetizing driving member 630 is used to drive the magnetizing head 620 to perform lifting motion. During magnetization, the magnetizing driving member 630 drives the magnetizing head 620 to move downward, shortening the time for the magnetizing head 620 to sleeve the iron core assembly 2 and improving the magnetization efficiency. After magnetization is completed, the magnetizing driving member 630 drives the magnetizing head 620 to move upward to avoid interference between the magnetizing head 620 and the jacking assembly 700.

[0077] In one embodiment, in combination with Figure 8 , the magnetizing mechanism 10 further includes a barcode scanner 804, and the barcode scanner 804 is located at the loading section of the second sliding assembly 500 for recording the code of the iron core assembly 2.

[0078] Specifically, the magnetizing mechanism 10 further includes a third feeding assembly 805, an outer diameter detection sensor 806, an inner diameter detection sensor 807, and a seventh position sensor 808. The third feeding assembly 805 provides the iron core assembly 2 to the second sliding assembly 500 along the second direction Y. The barcode scanner 804, the outer diameter detection sensor 806, the inner diameter detection sensor 807, and the seventh position sensor 808 are sequentially distributed at intervals along the conveying direction of the third feeding assembly 805 to sequentially perform barcode scanning, outer diameter detection, inner diameter detection, and position detection on the iron core assembly 2. When the detection is qualified, when reaching the seventh position sensor 808, the iron core assembly 2 is placed into the first positioning through hole 111 manually or by a transfer manipulator.

[0079] It should be understood that the magnitudes of the sequence numbers of the steps in the above embodiments do not mean the order of execution. The order of execution of each process should be determined according to its function and internal logic, and should not constitute any limitation to the implementation process of the embodiments of the present application.

[0080] The above are only optional embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present application shall be included within the protection scope of the present application.
