[0045] In this embodiment, the setting of the first insulating sleeve 5 not only plays an insulating role to prevent the current from directly passing through the product to be magnetized 100, ensuring the safety of operation, but also provides a stable support environment for the product to be magnetized 100, which helps to keep the position of the product to be magnetized 100 stable during the magnetizing process, thereby improving the accuracy and efficiency of magnetizing.

[0050] In an embodiment of the present application, the magnetizing device further comprises a base, and the insulator 1, the magnetic guide core 2, the first insulating sleeve 5, the magnetic yoke 6, and the second insulating sleeve 7 are placed on the base.
[0051] In the present embodiment, the base not only provides a stable support foundation for the magnetizing device, ensuring the relative positions of the components stable during the magnetizing process, but also facilitates the overall handling and installation of the magnetizing device. The design of the base can take into account factors such as heat dissipation and anti-skid to ensure the stability and safety of the magnetizing device during long-term operation.
[0052] Specifically, referring to Figure 1 , the base comprises a seat body 81 and a connecting plate 82 arranged at one end of the seat body 81, and the seat body 81 is in a cylindrical structure. The base, the insulator 1, the magnetic guide core 2, the first insulating sleeve 5, the magnetic yoke 6, and the second insulating sleeve 7 are all arranged on the connecting plate 82.
[0053] In an embodiment of the present application, referring to Figure 1 , the magnetizing device further comprises a pusher 9, and the pusher 9 is in sliding connection with the base. The pusher 9 is inserted into the first end of the product placement area and can move along the axis direction of the insulator 1.
[0054] In the present embodiment, the provision of the pusher 9 enables the magnetizing product 100 to be conveniently pushed out after the magnetizing is completed, facilitating subsequent collection and processing. The sliding connection of the pusher 9 with the base can ensure the smoothness and reliability of the pushing process, avoiding the risk of damage to the magnetizing product 100.

The provision of the sliding groove enables the pusher 9 to slide more stably on the base, ensuring the smooth progress of the pushing process. The driving part is used to provide the power for the movement of the pusher 9, which can be driven by manual operation or mechanical device, so that the pusher 9 can move stably along the axis direction of the insulator 1 and push the magnetizing product 100 out of the product placement area.

[0059] In this embodiment, the setting of the fixing member 11 can fix the to-be-magnetized product 100 during the magnetization process, preventing the to-be-magnetized product 100 from moving or falling off during the magnetization process, further improving the accuracy and efficiency of magnetization. The structure and material selection of the fixing member 11 also need to consider its stability and durability to ensure reliability in long-term use. Specifically, the fixing member 11 can be designed to be adjustable, which can be adjusted according to the size and shape of the to-be-magnetized product 100, thereby effectively fixing different specifications of to-be-magnetized products 100.

[0061] The setting of the fixing cover 12 not only protects the internal structure of the magnetizing device, preventing external environment from interfering with the magnetization process, but also helps to improve the overall structural stability of the magnetizing device. The close cooperation between the fixing cover 12 and the insulator 1, the first insulating sleeve 5 and the magnetically conductive core 2 can ensure that the magnetic field distribution during the magnetization process is more uniform, further improving the magnetization efficiency and quality. In addition, the design of the fixing cover 12 can also consider the heat dissipation performance to ensure that the magnetizing device can maintain stable temperature during long-term work, avoiding the adverse effects on the magnetization effect due to high temperature. In specific implementation, the fixing cover 12 can be fixed with the insulator 1 through screw connection, buckle connection and other ways to ensure the reliability and stability of the connection.
[0062] In another embodiment of the present application, the fixed cover 12 can also be provided with heat dissipation holes (not shown) to further improve the heat dissipation performance of the magnetizing device. The design of the heat dissipation holes can ensure that the heat generated by the magnetizing device during operation can be dissipated in time, avoiding problems such as reduced magnetizing efficiency or equipment damage caused by excessive temperature. At the same time, the setting of the heat dissipation holes can also play a role in ventilation, maintaining the dryness and cleanliness of the internal environment of the magnetizing device, which helps to prolong the service life of the equipment.
[0063] In another embodiment of the present application, the magnetizing device can also include a control system (not shown) for controlling the power-on and power-off of the coil 3, as well as adjusting the size and direction of the current, thereby achieving precise control over the magnetizing process.
