Description

Technical Field

[0001] This application relates to the field of magnetization technology, and in particular to a planar multipole magnetization coil for magnets. Background Technology

[0002] Magnets are widely used in modern industry and electronic equipment, such as in motors, sensors, and magnetic levitation devices. For these applications, it is often necessary to magnetize magnets through multiple poles to meet specific performance requirements.

[0003] However, the magnetizing coils currently used for multi-pole magnetization of magnetic planes have significant shortcomings in terms of magnetization effect. On the one hand, the magnetic field distribution generated by existing magnetizing coils is uneven, resulting in inconsistent magnetization intensity in different parts of the magnetic plane. This makes it difficult for the magnet to achieve ideal performance, affecting the overall quality and performance of subsequent products. On the other hand, because a large current needs to be passed through during the magnetization process, the existing magnetizing coil structure has defects in insulation protection, making it prone to leakage. Leakage not only threatens the personal safety of operators but may also damage equipment, increasing safety hazards and maintenance costs in the production process. At the same time, leakage may also interfere with surrounding electronic equipment, affecting the stability of the production environment. Utility Model Content

[0004] In view of the above problems, this application provides a multi-pole magnetizing coil for a magnetic plane to solve the significant shortcomings of existing magnetizing coils used for multi-pole magnetizing of magnetic planes in terms of magnetizing effect. On the one hand, the magnetic field distribution generated by existing magnetizing coils is uneven, resulting in inconsistent magnetization intensity in different parts of the magnetic plane, making it difficult for the magnet to achieve the ideal performance and affecting the overall quality and performance of subsequent products. On the other hand, since a large current needs to be passed through during the magnetization process, the existing magnetizing coil structure has defects in insulation protection, which easily leads to leakage. Leakage not only threatens the personal safety of operators but may also cause equipment damage, increasing safety hazards and maintenance costs in the production process. At the same time, leakage may also interfere with surrounding electronic equipment, affecting the stability of the production environment.

[0005] This application provides a planar multi-pole magnetizing coil. The planar multi-pole magnetizing coil includes a coil frame, which is a flat frame structure. A magnetizing coil winding is wound on the surface of the coil frame. The magnetizing coil winding includes multiple independent coil units, which are evenly distributed along the surface of the coil frame. A magnetizing mechanism and a leakage protection mechanism are provided on the outer surface of the magnetizing coil winding. The magnetizing mechanism is located around the coil units, and the leakage protection mechanism is located on the upper and lower surfaces of the magnetizing mechanism. A reinforcing mechanism is provided on the outer surface of the magnetizing mechanism.

[0006] In some embodiments, the magnetizing mechanism includes a magnetizing platform disposed around the coil unit, a magnetizing head fixedly mounted on the inner wall surface of the magnetizing platform, and a wire coil wound on the outer surface of the magnetizing head.

[0007] In some embodiments, a magnetizing plate is fixedly mounted on one end of the magnetizing head, a magnetizing ring is fixedly mounted on the inner surface of the magnetizing plate, and the coil unit is disposed inside the magnetizing ring.

[0008] In some embodiments, the leakage protection mechanism includes mounting legs fixedly connected to the upper and lower surfaces of the magnetizing ring, an insulating component fixedly connected to the inner side of one end of the mounting leg, and a current-collecting ring fixedly mounted at one end of the insulating component.

[0024] To facilitate understanding of the technical solutions in the embodiments of this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings.

[0025] This application provides a planar multipole magnetizing coil. Figure 1 This is a three-dimensional schematic diagram of the magnetizing coil in some embodiments of this application. Figure 2 This is a perspective view of the magnetization mechanism in some embodiments of this application. For example... Figure 1 , Figure 2 As shown, the planar multi-pole magnetizing coil includes a coil frame 1, which is a flat frame structure. A magnetizing coil winding 2 is wound on the surface of the coil frame 1. The magnetizing coil winding 2 includes multiple independent coil units, which are evenly distributed along the surface of the coil frame 1. A magnetizing mechanism 3 and a leakage protection mechanism 4 are provided on the outer surface of the magnetizing coil winding 2. The magnetizing mechanism 3 is located around the coil unit, and the leakage protection mechanism 4 is located on the upper and lower surfaces of the magnetizing mechanism 3. A reinforcing mechanism 5 is provided on the outer surface of the magnetizing mechanism 3. The magnetizing mechanism 3 includes a magnetizing platform 31 located around the coil unit. A magnetizing head 32 is fixedly installed on the inner wall surface of the magnetizing platform 31. A wire coil 33 is wound on the outer surface of the magnetizing head 32. A magnetizing plate 34 is fixedly installed at one end of the magnetizing head 32. A magnetizing ring 35 is fixedly installed on the inner surface of the magnetizing plate 34. The coil unit is located inside the magnetizing ring 35.

[0026] In the technical solution of this application embodiment, the magnetizing platform 31 provides a stable working platform for the magnetization operation. A magnetizing head 32 is fixedly installed on the inner wall surface of the magnetizing platform 31. The magnetizing head 32 is the key component for magnetization. A wire coil 33 is wound on its outer surface. When current passes through the wire coil 33, a magnetic field is generated. The magnetizing head 32 magnetizes the magnet. The magnetizing plate 34 and the magnetizing ring 35 further enhance the magnetization effect, so that the magnetic field can act more concentratedly on the magnet, improving the efficiency and quality of magnetization. 。

[0027] According to other embodiments of this application, such as Figure 3 As shown, the leakage protection mechanism 4 includes mounting legs 41 fixedly connected to the upper and lower surfaces of the magnetizing ring 35. An insulating component 42 is fixedly connected to the inner side of one end of the mounting leg 41. A current-collecting ring 43 is fixedly installed at one end of the insulating component 42. A first guide plate 44 is fixedly installed on the inner wall surface of the current-collecting ring 43. A flow-slowing plate 45 is fixedly installed on the outer surface of the first guide plate 44. A second guide plate 46 is fixedly installed on the inner surface of the flow-slowing plate 45. The inner surface of the second guide plate 46 is in contact with the outer surface of the coil frame 1.

[0028] In the technical solution of this embodiment, when leakage occurs, the current is first guided by the first guide plate 44, the current flow rate is reduced by the slow flow plate 45, and then the current is guided to a safe path by the second guide plate 46. At the same time, the insulation component 42 plays a good insulating role, effectively preventing the current from leaking to the outside, thereby achieving protection against leakage.

[0029] According to other embodiments of this application, such as Figure 4 As shown, the reinforcement mechanism 5 includes a mounting block 51 that is snapped into the inside of the magnetizing table 31. Limiting side plates 52 are installed on both sides of the mounting block 51. A buffer rod 53 is fixedly connected inside the limiting side plate 52. A reinforcement clamping plate 54 is fixedly installed at one end of the buffer rod 53. The inner surface of the reinforcement clamping plate 54 is in contact with the outer wall surface of the magnetizing table 31.

[0030] In the technical solution of this embodiment, when the magnetizing coil is subjected to external force, the mounting block 51, the limiting side plate 52, the buffer rod 53 and the reinforcing clamp 54 work together. Through the buffering effect of the buffer rod 53 and the reinforcement of the magnetizing platform 31 by the reinforcing clamp 54, the overall structural stability of the magnetizing coil is enhanced, and the risk of damage caused by external force is reduced.
