Description

Technical Field

[0001] The utility model relates to the technical field of demagnetization, in particular to a demagnetization component and a demagnetization device. Background Art

[0002] Materials may be magnetic after processing, and may absorb ferromagnetic materials, making them difficult to clean. Therefore, the processed materials generally need to be demagnetized first. High current demagnetization is a method of reducing or completely eliminating the magnetization of a magnet by applying a high current. When a magnet is exposed to a high current, the current will generate a strong magnetic field, the direction of which is opposite to the original magnetic field of the magnet, resulting in a reduction in the magnetization of the magnet or a complete disappearance. High current demagnetization is usually used in the following situations: 1. Reset the magnet: Some magnets may be disturbed or mismagnetized by external magnetic fields during use. By applying high current demagnetization, the magnet can be restored to its initial state and re-magnetized. 2. Demagnetization of magnets: Some applications require that the magnet be completely demagnetized at a specific moment in order to proceed to the next step. By applying high current demagnetization, the magnet can be effectively demagnetized so that it no longer has magnetism. After demagnetization, the material is completely non-magnetic, does not absorb other ferromagnetic materials, and is easy to clean. The wear resistance, durability and fatigue resistance of the magnetically treated material are significantly improved.

[0003] The demagnetization process is usually completed by a demagnetization machine or demagnetization device, but most of the demagnetization machines on the market are not easy to operate and have many safety hazards. Workers need to move the materials to the conveyor belt of the demagnetization machine and then press the start button. When the materials are finished on the conveyor belt, they need to free their hands to press the stop button to turn off the demagnetization machine. Moreover, during the demagnetization process, the materials are placed on the conveyor belt and are prone to move on the conveyor belt, resulting in insufficient demagnetization.
