Description

Technical Field

[0001] This utility model relates to the field of magnetizer technology, and in particular to a strong magnetic field uniform magnetizer. Background Technology

[0002] Various miniaturized, high-performance magnetic components, such as miniature speakers, vibration motors, and magnetic sensors, are widely used in electronic products such as smartphones, tablets, and laptops. These magnetic components have extremely high requirements for the uniformity and stability of the magnetic field. A strong magnetic field uniform magnetizer can meet their high-precision magnetization needs, ensuring the performance indicators of electronic devices such as sound quality, vibration effect, and sensing accuracy.

[0003] Currently, existing strong magnetic field uniform magnetizers all use heat-conducting plates for heat dissipation. However, the heat dissipation method using a single heat-conducting plate is ineffective and impractical. In addition, existing strong magnetic field uniform magnetizers cannot adjust their overall height according to actual needs, making them unsuitable for people of different heights. Furthermore, due to the position of the magnetizing material, uneven magnetization may occur, resulting in significant limitations and poor practicality. Utility Model Content

[0004] The purpose of this invention is to solve the problems of existing technologies that use heat conduction plates for heat dissipation, which have poor performance, poor practicality, and cannot adjust the overall height according to actual needs, making them unsuitable for people of different heights. Furthermore, due to the position of the magnetizing material, uneven magnetization may occur, resulting in significant limitations and poor practicality. Therefore, this invention proposes a strong magnetic field uniform magnetizer.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a strong magnetic field uniform magnetizer, comprising a main board, wherein first limiting plates are provided on both sides of the top of the main board, and a driving structure for driving the two first limiting plates to move in opposite directions is provided inside the main board, and first telescopic rods are provided on both sides of the top of the main board, with second limiting plates fixed to the output ends of the two first telescopic rods, a bracket fixed to the top of the main board, a second telescopic rod installed at the bottom of the bracket, a support plate fixed to the output end of the second telescopic rod, a magnetizing head installed at the bottom of the support plate, a fixing frame fixed to the top of the support plate, a second motor installed inside the fixing frame, and a fan fixed to the output end of the second motor.

[0006] Preferably, the drive structure includes a first motor mounted on the inner wall of the motherboard, the output end of the first motor is fixed with a bidirectional screw, both ends of the outer wall of the bidirectional screw are threaded with movable plates, both ends of the two movable plates are slidably connected with limit posts, and the bottom ends of the two first limit plates penetrate the motherboard and are respectively fixed to the two movable plates.

[0007] Preferably, the motherboard has a base plate at each of its four lower corners, and a third telescopic rod is installed at the top of each of the four base plates. The output ends of the four third telescopic rods are fixed to the motherboard.

[0008] Preferably, a connecting plate is bolted to the top of the fixing frame, the second motor is mounted on the bottom of the connecting plate, and handles are fixed to both sides of the top of the connecting plate.

[0009] Preferably, the end of the bidirectional screw away from the first motor is rotatably connected to the main board, and both ends of the limiting post are fixed to the main board.

[0010] Preferably, the top two sides of the main board are fixed with fixing plates, and the landing ends of the two first telescopic rods are respectively installed on the opposite ends of the two fixing plates.

[0011] Preferably, the top of the bracket has an opening that matches the fixing frame, and both sides of the top of the main board have moving grooves that match the first limiting plate.

[0012] Preferably, a heat-conducting plate is installed inside the support plate at the top of the magnetizing head, and an air outlet groove is provided on the side wall of the fixing frame.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] In this invention, the operation of the first motor drives the bidirectional screw to rotate, causing two moving plates to move towards each other under the limitation of the limiting post. This allows for left-right limiting adjustment of the magnetizing material placed on the main board. Furthermore, the synchronous operation of the two first telescopic rods drives the two second limiting plates to move towards each other, thereby allowing for front-back limiting adjustment of the magnetizing material on the main board. This ensures the magnetizing material is centered on the magnetizing head above it, resulting in more uniform magnetization and enhanced practicality. Additionally, the operation of the second motor drives the fan to rotate, quickly dissipating heat from the heat-conducting plate for better heat dissipation. Finally, the synchronous operation of the four third telescopic rods allows for the overall lifting and lowering of the main board, enabling adjustment to the working height required by the operator, further enhancing its practicality.

It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0022] Example 1, such as Figures 1-4 As shown, this utility model provides a strong magnetic field uniform magnetizer, including a main board 1. First limiting plates 2 are provided on both sides of the top of the main board 1. A driving structure 3 is provided inside the main board 1 to drive the two first limiting plates 2 to move in opposite directions. First telescopic rods 6 are provided on both sides of the top of the main board 1. Second limiting plates 7 are fixed to the output ends of the two first telescopic rods 6. A bracket 8 is fixed to the top of the main board 1. A second telescopic rod 9 is installed at the bottom of the bracket 8. A support plate 10 is fixed to the output end of the second telescopic rod 9. A magnetizing head 11 is installed at the bottom of the support plate 10. A fixing frame 12 is fixed to the top of the support plate 10. A second motor 16 is installed inside the fixing frame 12. A fan 17 is fixed to the output end of the second motor 16.

[0023] The overall effect of Embodiment 1 is that the material to be magnetized is placed on the motherboard 1, and the operation of the drive structure 3 drives the two first limiting plates 2 to move towards each other, thereby adjusting the front and rear limits of the magnetized material placed on the motherboard 1 so that the magnetized material is at the center of the magnetizing head 11 above it. After the limit is set, the operation of the second telescopic rod 9 drives the support plate 10 to descend, thereby driving the magnetizing head 11 to magnetize the material. In addition, the device can drive the fan 17 to rotate through the operation of the second motor 16, thereby quickly dissipating the heat dissipated by the heat conduction plate 13, resulting in better heat dissipation.

[0024] Example 2, as Figures 1-4 As shown, the drive structure 3 includes a first motor 301 mounted on the inner wall of the main board 1. A bidirectional screw 302 is fixed to the output end of the first motor 301. Moving plates 303 are threaded to both ends of the outer wall of the bidirectional screw 302. Limiting posts 304 are slidably connected to both ends of the two moving plates 303. The bottom ends of the two first limiting plates 2 penetrate the main board 1 and are fixed to the two moving plates 303 respectively. Base plates 20 are provided at the four lower corners of the main board 1. Third telescopic rods 21 are installed at the top of each of the four base plates 20. The output ends of the four third telescopic rods 21 are fixed to the main board 1. A connecting plate 14 is installed at the top of the fixing frame 12 via bolts 15. The second motor 1... 6 is installed at the bottom of the connecting plate 14. Handles 19 are fixed on both sides of the top of the connecting plate 14. The end of the bidirectional screw 302 away from the first motor 301 is rotatably connected to the main board 1. Both ends of the limiting post 304 are fixed to the main board 1. Fixing plates 5 are fixed on both sides of the top of the main board 1. The sitting ends of the two first telescopic rods 6 are respectively installed on the opposite ends of the two fixing plates 5. The top of the bracket 8 is provided with an opening 22 that matches the fixing frame 12. The top of the main board 1 is provided with a moving groove 4 that matches the first limiting plate 2. A heat-conducting plate 13 is installed inside the support plate 10 at the top of the magnetizing head 11. An air outlet groove 18 is provided on the side wall of the fixing frame 12.

[0025] The effect achieved by the entire embodiment 2 is that, through the synchronous operation of the four third telescopic rods 21, the main board 1 can be raised and lowered as a whole, so that it can be adjusted according to the working height required by the actual staff, making it more practical. Through the operation of the first motor 301, the bidirectional screw 302 is driven to rotate, so that the two moving plates 303 move towards each other under the limit of the limit post 304, thereby enabling the left and right limit adjustment of the magnetized material placed on the main board 1. Through the setting of the connecting plate 14 and the bolt 15, the second motor 16 and the fan 17 can be installed and removed, which is convenient for replacement and maintenance.

[0026] Working principle: When in use, the first motor 301 drives the bidirectional screw 302 to rotate, causing the two moving plates 303 to move towards each other under the limitation of the limiting post 304. This allows for left and right limit adjustment of the magnetizing material placed on the main board 1. Then, through the synchronous operation of the two first telescopic rods 6, the two second limiting plates 7 can be driven to move towards each other, thereby allowing for front and rear limit adjustment of the magnetizing material placed on the main board 1, so that the magnetizing material is at the center of the magnetizing head 11 above it. After the limit is set, through the operation of the second telescopic rod 9, the support plate 10 is driven to descend, thereby driving the magnetizing head 11 to magnetize the magnetizing material. In addition, through the operation of the second motor 16, the fan 17 can be driven to rotate, thereby quickly dissipating the heat dissipated by the heat conduction plate 13, resulting in better heat dissipation. Furthermore, through the synchronous operation of the four third telescopic rods 21, the main board 1 can be raised and lowered as a whole, allowing it to be adjusted according to the actual working height required by the staff, making it more practical.
