Description

Technical Field

[0001] This invention relates to the field of electric motor manufacturing technology, specifically to a dual-magnet electric motor assembly mechanism and assembly process. Background Technology

[0002] An electric motor is a device that converts electrical energy into mechanical energy. It utilizes a energized coil to generate a magnetic field that acts on the rotor, thus creating a magnetoelectric torque. A dual-magnet motor has two magnets mounted on the same shaft. The magnetic poles of the two magnets have a fixed deflection relative to each other. During operation, the two magnets rotate in a coordinated manner under the electromagnetic influence of their respective coils, thereby driving the shaft to rotate continuously and enabling the dual-magnet motor to output power continuously.

[0003] Due to their strong continuous operation and stable power output, twin-magnet motors are widely used in many electrical components, leading to a significant increase in production demand. However, their mass production requires extremely high quality and efficiency. In the assembly and production of twin-magnet motors, the magnetic pole positioning between the two magnets on the shaft and the positioning between the magnets and the coil are particularly important. Magnetic pole positioning must be controlled by the angle between the N and S poles of the two magnets; otherwise, fluctuations will occur during the rotational connection of the two magnets under the electromagnetic influence of the coil, resulting in unstable motor output. Furthermore, if the positioning between the magnets and the coil is misaligned, the electromagnetic field generated by the coil will deviate from the magnetic field of the magnets, resulting in weak or unstable rotational action of the magnets. Therefore, precise positioning of the twin magnets is crucial during the assembly process when mounting them onto the shaft.

[0004] Furthermore, when assembling a rotor with dual magnets into the stator, it is crucial to ensure that the rotor is properly positioned and inserted into the stator without colliding with it. Otherwise, the position of the magnets on the rotor may change, or the magnets may scrape against the stator, generating magnetic powder. This magnetic powder can be affected by the magnetic field of the coils, interfering with the rotor's rotation and affecting the motor's operating accuracy. Simultaneously, for dual-magnet motors using a worm gear as the output drive, precise positioning and assembly of the worm gear are also necessary. This ensures that the worm gear installation does not affect the rotor's installation accuracy on the stator, guaranteeing the overall assembly precision of the dual-magnet motor. Summary of the Invention

[0005] To ensure the precise positioning and assembly of the two magnets and the rotor with the two magnets in a dual-magnet motor, so as to guarantee that the assembled dual-magnet motor has good output performance, this invention provides a dual-magnet motor assembly mechanism.

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0047] The dual-magnet motor assembly mechanism of the present invention can be used in the production of dual-magnet motors to achieve precise assembly of the various components of the dual-magnet motor, thereby obtaining a dual-magnet motor with good working performance.

[0048] For details, please refer to Figure 1 The image shows a dual-magnet motor to be assembled. The dual-magnet motor includes a coil 1, a stator 2, and a rotor 3. The rotor 3 is housed within the stator 2 and is rotatably mounted on the stator 2 via bearings 5. Please refer to [link to relevant documentation]. Figure 2As shown, the rotor 3 includes a shaft 33 and magnets I 31 and II 32 tightly fitted onto the shaft 33. Magnets I 31 and II 32 are relatively fixed to the shaft 33 and do not rotate relative to it. Magnets I 31 and II 32 can rotate synchronously with the shaft 33, generating a corresponding output when the shaft 33 rotates. The bearing 5 is sleeved on the shaft 33 and located between the shaft 33 and the stator 2. There is a gap between magnets I 31 and II 32 and the stator 2. Magnets I 31 and II 32 have a magnetic pole deflection angle relative to each other. The N pole on magnet I 31 and the S pole on magnet II 32 are deviated from each other by 18°, that is, the S pole on magnet I 31 and the N pole on magnet II 32 are deviated from each other by 18°, or even the N pole on magnet I 31 corresponds to the N pole on magnet II 32. The coil 1 includes two coils, both of which are located outside the stator 2 and correspond to magnet I 31 and magnet II 32 respectively. When the two coils 1 are energized, they can generate magnetic fields, and the corresponding magnetic fields can interact with the corresponding magnets I 31 and II 32 respectively.

[0049] When in operation, the two coils 1 are energized and generate a magnetic field. Magnets I 31 and II 32 are alternately acted upon and rotate, which in turn drives the rotating shaft 33 to rotate continuously, so as to continuously output power.

[0050] In a preferred embodiment, the stator 2 is composed of an inner stator portion 21 and an outer stator portion 22, which facilitates the rotor 3. Specifically, magnet I 31 and magnet II 32 each correspond to one stator 2. The inner stator portions 21 of the two stators 2 are fixedly connected to each other and located at the inner ends, while the outer stator portions 22 of the two stators 2 respectively mate with the two inner stator portions 21 from the left and right ends. Optionally, the inner stator portions 21 and the outer stator portions 22 have mutually compatible mating structures, such as a toothed meshing structure.

[0051] Furthermore, an output worm gear 4 can be fitted to the front end of the rotating shaft 33. The output worm gear 4 can rotate synchronously with the rotating shaft 33 to transmit power. The output worm gear 4 can transmit power through a matching worm, or even with a corresponding gear set to achieve stable power output.

[0052] Example 1

[0053] The dual-magnet motor assembly mechanism of the present invention can be used for the assembly and production of the above-mentioned dual-magnet motor or similar dual-magnet motors. The dual-magnet motor of the present invention will be described in detail below with reference to specific embodiments.

[0054] For details, please refer to Figure 4 , Figure 6 , Figure 8As shown, the dual-magnet motor assembly mechanism of the present invention includes a magnet positioning component 6, a shaft assembly component 7, and a rotor assembly component 8. The magnet positioning component 6, the shaft assembly component 7, and the rotor assembly component 8 are arranged sequentially according to the assembly process of the dual-magnet motor. During the assembly and production of the dual-magnet motor, the magnet positioning component 6 is activated to achieve the magnetic pole positioning and deflection assembly of magnet I 31 and magnet II 32, while the shaft assembly component 7 is activated to achieve the positioning assembly of rotor 3, and finally, the rotor assembly component 8 achieves the positioning assembly of rotor 3 within stator 2.

[0055] The magnet positioning assembly 6 includes a first positioning clamp 61 and a second positioning clamp 62. During the magnetic pole positioning and deflection assembly of magnet I 31 and magnet II 32, the first positioning clamp 61 and the second positioning clamp 62 are used to clamp and position magnet I 31 and magnet II 32, respectively. Both the first positioning clamp 61 and the second positioning clamp 62 are movable, including vertical, horizontal, and lateral movement. Furthermore, relative rotation between the first positioning clamp 61 and the second positioning clamp 62 is possible. Specifically, both the first positioning clamp 61 and the second positioning clamp 62 can rotate freely, or one of them can rotate freely to achieve relative rotation between them.

[0056] After magnets I 31 and II 32 have completed their magnetic pole positioning, the first positioning clamp 61 and the second positioning clamp 62 respectively clamp magnets I 31 and II 32. Magnets I 31 and II 32 can be separated by the relative movement of the first positioning clamp 61 and the second positioning clamp 62. Then, by rotating the first positioning clamp 61 and the second positioning clamp 62 relative to each other, magnets I 31 and II 32 will rotate relative to each other, thereby achieving magnetic pole positioning deflection and completing the positioning and assembly of the magnets.

[0057] Specifically, both the first positioning clamp 61 and the second positioning clamp 62 include two cooperating jaws, each jaw having a clamping portion 621, and each jaw is made of a non-magnetic material, so it will not have a magnetic attraction with the magnet. In the specific embodiment shown, both the first positioning clamp 61 and the second positioning clamp 62 include two jaws that cooperate front to back. The clamping portions 621 on the two jaws, when engaged, form a polygonal hole structure adapted to the magnet. This polygonal hole structure allows for good clamping of the magnet, whose outer periphery is arc-shaped.

[0058] The rotating shaft assembly 7 includes a movable rotating shaft clamp, which is specifically a rod clamp of various forms and can move up and down, forward and backward, and left and right. During the assembly of the rotor 3, the rotating shaft clamp holds the rotating shaft 33 and positions it to be inserted into the magnet I 31 and magnet II 32, thereby completing the positioning and assembly of the entire rotor 3.

[0059] Furthermore, the rotating shaft assembly 7 also includes a first magnet blocking plate 71 and a second magnet blocking plate 72. Specifically, both the first magnet blocking plate 71 and the second magnet blocking plate 72 are made of non-magnetic materials and will not generate magnetic attraction with the magnets. During the assembly of the rotor 3, as the rotating shaft 33 is positioned and inserted into the magnets I 31 and II 32, the first magnet blocking plate 71 and the second magnet blocking plate 72 can respectively abut against the side of the magnets I 31 and II 32 opposite to the insertion of the rotating shaft 33 to tighten the magnets I 31 and II 32, preventing the magnets I 31 and II 32 from shifting during the insertion of the rotating shaft 33, thus ensuring the assembly precision of the rotor 3.

[0060] Preferably, the first magnet blocking plate 71 and the second magnet blocking plate 72 can be planar plates with an area larger than that of the magnet. Both the first magnet blocking plate 71 and the second magnet blocking plate 72 have through-hole clearance positions that can accommodate the rotating shaft 33. In the specific embodiment shown, the first magnet blocking plate 71 and the second magnet blocking plate 72 respectively have a first through-hole clearance position 711 and a second through-hole clearance position 721 corresponding to the rotating shaft 33. The first through-hole clearance position 711 and the second through-hole clearance position 721 are notches opened at the lower ends of the first magnet blocking plate 71 and the second magnet blocking plate 72, respectively. When positioning and blocking magnet I 31 and magnet II 32, the first magnet blocking plate 71 and the second magnet blocking plate 72 move downwards, causing the positioning shaft 10 to enter the corresponding first through-hole clearance position 711 and second through-hole clearance position 721. This effectively positions and blocks the magnets without affecting the positioning of the positioning shaft 10 and the assembly of the rotating shaft 33.

[0061] The rotor assembly assembly 8 includes a guide clamp 81. The guide clamp 81 is made of a non-magnetic material and will not be magnetically attracted to the magnet. The guide clamp 81 can move up and down, forward and backward, and left and right. When assembling the rotor 3 in the stator 2, the guide clamp 81 can hold the rotor 3 with the magnet and position the rotor 3 in the stator 2 to complete the assembly.

[0062] In a preferred embodiment, the guide clamp 81 has a clamping portion 811 adapted to clamp the rotating shaft 33, which can stably clamp the rotating shaft 33 of the rotor 3. Moreover, the clamping portion 811 can move left and right along the axial direction through the stator 2. Specifically, the clamping portion 811 of the guide clamp 81 is designed as a slender structure with a length greater than that of the stator 2 and an outer diameter smaller than that of the stator 2, so that the clamping portion 811 can penetrate the stator 2 and can move left and right through the stator 2. When assembling the rotor 3 within the stator 2, the clamping part 811 passes from the left end of the stator 2 to the right end of the stator 2 and clamps the left end of the rotor 3's shaft 33. Then, the guide clamp 81 moves to the left, thereby directionally pulling and assembling the entire rotor 3 into the inner stator part 21. At the same time, it can adjust and guide the coaxiality of the inner stator part 21 and the outer stator part 22 and ensure that the rotor 3 does not interfere with the inner stator part 21 and the outer stator part 22 when it is installed in the stator 2.

[0063] Furthermore, for a dual-magnet motor with an output worm gear 4 mounted at the front end, the rotor assembly assembly 8 is also equipped with a worm gear positioning clamp, which can move up and down, forward and backward, and left and right. During the process of pre-assembling the output worm gear 4 onto the rotor shaft 33 of the rotor 3 and then assembling the rotor 3 into the stator 2, the output worm gear 4 can be positioned and clamped by the corresponding worm gear positioning clamp during the process of the rotor 3 being pulled into the stator 2 by the guide clamp 81. The output worm gear 4 moves synchronously with the rotor 3 through the directional movement of the worm gear positioning clamp until the rotor 3 completes its positioning assembly within the stator 2, thus avoiding any impact on the assembly accuracy of the rotor 3 caused by the assembly of the output worm gear 4.

[0064] Specifically, the worm gear positioning clamp includes a first worm gear clamp 82 and a second worm gear clamp 83. When positioning and clamping the output worm gear 4, the first worm gear clamp 82 and the second worm gear clamp 83 can approach each other along the axial direction of the rotating shaft 33 to position and clamp the output worm gear 4 mounted on the rotating shaft 33. Both the first worm gear clamp 82 and the second worm gear clamp 83 have clamping clearance positions to avoid damaging the output worm gear 4 during clamping.

[0065] In another preferred embodiment, the dual-magnet motor assembly mechanism is further equipped with a fixed mold base 9. Specifically, the fixed mold base 9 has coil fixing positions and stator fixing positions. When assembling the rotor 3 on the stator 2, the coil 1 and the stator 2 can be pre-positioned and fixed on the coil fixing positions and stator fixing positions of the fixed mold base 9, respectively, so that the rotor 3 after positioning and assembly can be precisely aligned with the coil 1 and the stator 2, ensuring the assembly quality of the overall dual-magnet motor assembly mechanism.

[0066] The present invention also provides an assembly and manufacturing process for the above-described dual-magnet motor or similar dual-magnet motor. The assembly process of the dual-magnet motor of the present invention will be described in detail below with reference to specific embodiments.

[0067] Example 2

[0068] The assembly process of the dual-magnet motor of the present invention, using the dual-magnet motor assembly mechanism of Embodiment 1 above, includes the following steps:

[0069] S1. Magnet I 31 and magnet II 32 are assembled onto the positioning shaft 10 using a clearance fit. Magnet I 31 and magnet II 32, assembled onto the positioning shaft 10 with a clearance fit, can magnetically attract each other. Please refer to [link to relevant documentation]. Figure 3 As shown, the S pole of magnet I 31 and the N pole of magnet II 32 are attracted by opposite poles, and the N pole of magnet I 31 and the S pole of magnet II 32 are attracted by opposite poles, thus completing the magnetic pole positioning.

[0070] S2, please refer to Figure 4 As shown, the first positioning clamp 61 and the second positioning clamp 62 of the magnet positioning assembly 6 are moved and positioned, and respectively clamp magnet I 31 and magnet II 32. In the axial direction of the positioning shaft 10, the first positioning clamp 61 and the second positioning clamp 62 are separated from each other along the axial direction by relative movement, thereby orienting magnet I 31 and magnet II 32 to be separated from each other.

[0071] S3. The first positioning clamp 61 and the second positioning clamp 62 rotate relative to each other, causing the corresponding clamped magnets I 31 and II 32 to rotate relative to each other, completing the magnetic pole positioning deflection. In the specific embodiment shown, the first positioning clamp 61 remains fixed, while the second positioning clamp 62 rotates around the positioning axis 10, thereby rotating relative to the first positioning clamp 61, which in turn causes magnets I 31 and II 32 to rotate relative to each other around the axis. After the relative rotation, the dissimilar magnetic poles of magnets I 31 and II 32 are deflected, and the magnetic attraction between magnets I 31 and II 32 weakens, or even becomes repulsive.

[0072] Specifically, for the magnetic pole distribution characteristics of magnet I31 and magnet II32, please refer to [link / reference needed]. Figure 5 As shown, the first positioning clamp 61 and the second positioning clamp 62 rotate relative to each other by 18°, which in turn causes magnet I 31 and magnet II 32 to rotate relative to each other by 18°, so that the S poles of magnet I 31 and magnet II 32 correspond to each other and the N poles correspond to each other, and they have a magnetic repulsion effect on each other.

[0073] S4, please refer to Figure 6As shown, the first magnet blocking plate 71 and the second magnet blocking plate 72 of the rotating shaft assembly 7 are moved and positioned, and respectively abut against the left ends of magnet I 31 and magnet II 32 by avoiding the positioning shaft 10, thereby fixing magnet I 31 and magnet II 32 to the left. Then, the rotating shaft clamp of the rotating shaft assembly 7 clamps the rotating shaft 33 and moves it for positioning. Please refer to... Figure 7 As shown, in the axial direction of the positioning shaft 10, the rotating shaft clamp drives the rotating shaft 33 to move to the left, pushing the positioning shaft 10 out from the magnet I 31 and magnet II 32, and causing the rotating shaft 33 to pass into the magnet I 31 and magnet II 32, thereby completing the assembly of the rotor 3.

[0074] S5. Assemble the rotor 3 within the stator 2 and the bearing 5 to complete the assembly of the dual-magnet motor. Further, an output worm gear 4 can be assembled at the output end of the shaft 33 to obtain a dual-magnet motor with output worm gear 4 driving the output.

[0075] Example 3

[0076] This embodiment is the same as Embodiment 2. For further details, please refer to... Figure 9 As shown, in the assembly process of the dual-magnet motor in this embodiment, after the rotor 3 is assembled, the following steps are performed:

[0077] S51' The inner stator portion 21 and outer stator portion 22 of the coil 1 and stator 2 are pre-positioned and fixed on the fixed mold base 9. The two coils 1 correspond to the two stators 2. The left end of the rotating shaft 33 of the rotor 3 is clamped by the guide clamp 81 of the rotor assembly assembly 8, and the rotor 3 is pulled into the positioning assembly in the stator 2 by the directional movement of the guide clamp 81 in the axial direction.

[0078] S52', Complete the assembly of bearing 5 on shaft 33.

[0079] S53' Then, the output worm gear 4 is assembled at the output end of the rotating shaft 33 to complete the assembly of the dual magnet motor.

[0080] Example 4

[0081] This embodiment is the same as Embodiment 2. For further details, please refer to... Figure 8 and Figure 9 As shown, in the assembly process of the dual-magnet motor in this embodiment, after the rotor 3 is assembled, the following steps are performed:

[0082] S51”, complete the assembly of bearing 5 on shaft 33.

[0083] S52”, and then, the output worm gear 4 is assembled at the output end of the rotating shaft 3.

[0084] S53”, the inner stator portion 21 and outer stator portion 22 of the coil 1 and stator 2 are pre-positioned and fixed on the fixed mold base 9. The two coils 1 correspond to the two stators 2. The left end of the rotor shaft 33 of the rotor 3 is clamped by the guide clamp 81 of the rotor assembly assembly 8. At the same time, the output worm 4 is positioned and clamped by the worm positioning clamp. The rotor 3 with bearing 3 and output worm 4 is moved by the axial directional movement of the guide clamp 81. The rotor 3 is pulled into the positioning assembly in the stator 2. The worm positioning clamp moves synchronously with the rotor 3, so that the output worm 4 keeps moving synchronously with the rotor 3 until the rotor 3 is inserted and positioned in the stator 2, thus completing the assembly of the dual magnet motor.
