Description

Technical Field

[0001] This utility model relates to a magnetization device, specifically a uniform magnetization device for rare earth permanent magnet materials, belonging to the field of rare earth magnetization technology. Background Technology

[0002] Rare earth permanent magnet materials are a class of special magnetic materials that incorporate rare earth metals as alloying elements. Due to their superior properties such as high remanence, high coercivity, and high energy product, they play a crucial role in numerous fields, including new energy vehicles, wind power generation, and electronic communications. Currently, the industry commonly uses a strong magnetic field to magnetize rare earth permanent magnet materials, and pulse magnets are a frequently used device for this operation. They generate pulse currents of hundreds of amperes instantaneously, thereby exciting a strong magnetic field, enabling the magnetization of rare earth permanent magnet materials in an extremely short time.

[0003] However, existing magnetization devices for rare earth permanent magnet materials still have certain problems. Specifically, during the magnetization process, due to limitations in equipment structure and technology, it is difficult to magnetize multiple surfaces of the rare earth permanent magnet material simultaneously. This results in each magnetization operation targeting only one surface, requiring manual adjustment of the material's position and angle to magnetize other surfaces. However, the randomness of manual operation and individual differences make it difficult to maintain consistent magnetization time for each operation. This inconsistency in magnetization time leads to differences in the magnetization degree of different parts of the material, making it difficult to achieve uniform magnetization of the rare earth permanent magnet material, which seriously affects the final performance and quality of the material. Therefore, a uniform magnetization device for rare earth permanent magnet materials is proposed. Utility Model Content

[0004] In view of this, the present invention provides a uniform magnetization device for rare earth permanent magnet materials to solve or alleviate the technical problems existing in the prior art, and at least provides a beneficial option.

[0005] The technical solution of this utility model embodiment is implemented as follows: a uniform magnetization device for rare earth permanent magnet materials includes a frame, an adjustment component is provided on the frame, and two conveyor belts are provided inside the frame;

[0006] The adjustment assembly includes a support frame, a support ring, a rotating ring, a friction ring, a limiting frame, a mounting frame, a limiting plate, a friction plate, a spring, and a guide rod;

[0007] The support frame is installed on the outer side wall of the two conveyor belts. The support ring is fixedly connected to the upper surface of the support frame. The rotating ring is rotatably connected to the outer side wall of the support ring. The friction ring is fixedly connected to the outer side wall of the rotating ring.

The guide rod is fixedly connected to the outer side wall of the friction plate at equal intervals. The guide rod is slidably connected to the inside of the limiting plate. The spring is sleeved on the outer side wall of the guide rod.

[0008] More preferably, two drive rollers are installed inside the frame, and the conveyor belt is installed on the outer side wall of the two drive rollers.

[0010] More preferably, one end of the spring abuts against the friction plate, and the other end of the spring abuts against the limiting plate.

[0011] More preferably, the limiting frame contains a rare earth permanent magnet material body, and the frame is respectively equipped with a first magnetizing plate and a second magnetizing plate.

[0013] More preferably, the second magnetizing plate is symmetrically located on the left and right sides of the rare earth permanent magnet material body.

[0014] More preferably, the mounting bracket is located between the first magnetizing plate and the second magnetizing plate.

[0015] The present invention has the following advantages due to the adoption of the above technical solution:

[0016] This invention uses a conveyor belt to transport the rare earth permanent magnet material body. During the transport process, a first magnetizing plate magnetizes the upper, lower, left, and right sides of the rare earth permanent magnet material body.

Detailed Implementation

[0026] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this invention. Therefore, the drawings and description are considered exemplary in nature and not restrictive.

[0027] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0028] like Figures 1-6As shown, this utility model embodiment provides a uniform magnetization device for rare earth permanent magnet materials, including a frame 31, an adjustment component 101 on the frame 31, two conveyor belts 33 inside the frame 31, and two drive rollers 32 installed inside the frame 31. The conveyor belts 33 are installed on the outer walls of the two drive rollers 32. During operation, with the cooperation of the two drive rollers 32, the conveyor belts 33 drive the support frame 11 to move, thereby realizing the conveying of rare earth permanent magnet materials.

[0029] The adjustment assembly 101 includes a support frame 11, a support ring 12, a rotating ring 13, a friction ring 14, a limiting frame 15, a mounting frame 16, a limiting plate 17, a friction plate 18, a spring 19, and a guide rod 20;

[0030] The support frame 11 is installed on the outer side wall of the two conveyor belts 33, the support ring 12 is fixedly connected to the upper surface of the support frame 11, and the rotating ring 13 is rotatably connected to the outer side wall of the support ring 12. When the rotating ring 13 rotates, it can adjust the position of the rare earth permanent magnet material so that its two unmagnetized surfaces rotate to the sides, thereby achieving uniform magnetization.

[0031] The limiting frame 15 is fixedly connected to the upper surface of the rotating ring 13. The rare earth permanent magnet material body 21 is placed inside the limiting frame 15. The position of the rare earth permanent magnet material body 21 can be limited by the limiting frame 15. When adjusting the position, the rare earth permanent magnet material body 21 can remain stable.

[0032] The limiting plate 17 is fixedly connected to the upper surface of the frame 31 via the mounting bracket 16. The guide rod 20 is fixedly connected to the outer side wall of the friction plate 18 at equal intervals. The guide rod 20 is slidably connected to the inside of the limiting plate 17. Through the cooperation of the limiting plate 17, the mounting bracket 16 and the guide rod 20, the position of the friction plate 18 can be limited.

[0033] In one embodiment, the friction ring 14 is fixedly connected to the outer wall of the rotating ring 13, and the position of the friction plate 18 corresponds to the position of the friction ring 14. When the conveyor belt 33 drives the support frame 11 to move, the support frame 11 drives the rare earth permanent magnet material body 21 in the limiting frame 15 to move. When the friction ring 14 moves to the position corresponding to the friction plate 18, the friction plate 18 is in contact with the friction ring 14. Since the position of the friction plate 18 is limited by the mounting frame 16, as the friction ring 14 moves, the friction ring 14 drives the rotating ring 13 to rotate on the support ring 12. The rotating ring 13 drives the limiting frame 15, and the limiting frame 15 drives the rare earth permanent magnet material body 21. Then, the position of the rare earth permanent magnet material body 21 can be adjusted so that its two unmagnetized sides are adjusted to the sides so as to magnetize it.

[0034] The friction plate 18 on the side away from the guide rod 20 and the outer wall of the friction ring 14 are provided with abrasive particles. The abrasive particles can increase the friction and prevent slippage. The front and rear ends of the friction plate 18 are both inclined surfaces, which can guide the friction ring 14 and reduce the impact on the friction ring 14.

[0035] In one embodiment, spring 19 is sleeved on the outer wall of guide rod 20, one end of spring 19 abuts against friction plate 18, and the other end of spring 19 abuts against limiting plate 17. Under the push of spring 19, friction plate 18 remains in contact with friction ring 14, thereby increasing friction and preventing slippage, so that friction ring 14 can stably drive rare earth permanent magnet material body 21 to rotate.

[0036] In one embodiment, a first magnetizing plate 34 and a second magnetizing plate 35 are respectively installed on the frame 31. The first magnetizing plate 34 is located in the upper, lower, left and right directions of the rare earth permanent magnet material body 21, and the upper surface, lower surface, left side and right side of the rare earth permanent magnet material body 21 can be magnetized through the first magnetizing plate 34.

[0037] The second magnetizing plate 35 is symmetrically located on the left and right sides of the rare earth permanent magnet material body 21. The mounting bracket 16 is located between the first magnetizing plate 34 and the second magnetizing plate 35. After the upper surface, lower surface, left side and right side of the rare earth permanent magnet material body 21 are magnetized, the rare earth permanent magnet material body 21 is adjusted in position with the cooperation of the adjusting component 101, so that the two unmagnetized sides are rotated to the sides. At this time, the two sides can be magnetized by the second magnetizing plate 35, thereby achieving uniform magnetization of the rare earth permanent magnet material.

[0038] In operation, the rare earth permanent magnet material body 21 is placed inside the limiting frame 15. The transmission roller 32 drives the conveyor belt 33, which in turn drives the support frame 11, thus conveying the rare earth permanent magnet material body 21. The first magnetizing plate 34 magnetizes the upper, lower, left, and right surfaces of the rare earth permanent magnet material body 21. Subsequently, the support frame 11 moves to the position corresponding to the mounting frame 16, and the friction ring 14 contacts the friction plate 18. The friction plate 18 is pushed by the friction ring 14, and the spring 19 is stressed. Compression occurs when the friction plate 18 and friction ring 14 are tightly fitted together. As the conveyor belt 33 moves, the friction ring 14 drives the rotating ring 13 to rotate, which in turn drives the limiting frame 15. The limiting frame 15 then drives the rare earth permanent magnet material body 21. At this point, the position of the rare earth permanent magnet material body 21 can be adjusted so that its two unmagnetized sides are moved to the sides. Then, the second magnetizing plate 35 magnetizes the two unmagnetized sides, thereby achieving uniform magnetization of the rare earth permanent magnet material. After magnetization is completed, the rare earth permanent magnet material body 21 is removed from the limiting frame 15.

[0039] Compared with the prior art, this utility model, by setting the adjustment component 101, can automatically adjust the position of the rare earth permanent magnet material body 21 when it is being transported, replacing the traditional manual operation steps, realizing uniform magnetization of the rare earth permanent magnet material body 21, and ensuring the final performance and quality of the material.

[0040] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in this utility model, and these should all be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
