Description

Technical Field

[0001] The utility model belongs to the technical field of nanocrystalline shielding sheet processing, and particularly relates to a magnetic breaking mechanism for preparing nanocrystalline shielding sheets. Background Technique

[0002] At present, nanocrystalline shielding sheets have been widely applied to electronic devices such as household appliances, smart phones, drones, and electric vehicles. However, technical problems have been encountered in the manufacturing process. Especially when the anti-saturation current of wireless charging devices is getting larger and larger, high magnetic permeability, low magnetic loss, and high efficiency are required. This puts higher requirements on high-Bs nanocrystalline tapes. Because the iron content of Bs nanocrystalline tapes is very high, the iron loss is relatively large, resulting in a relatively high resistance under the same magnetic permeability, thereby affecting the efficiency.

[0003] When preparing nanocrystalline shielding sheets, one surface of the Bs nanocrystalline tape needs to be subjected to magnetic breaking treatment (the other surface of the Bs nanocrystalline tape is used to bond an ultra-thin double-sided tape) to improve the performance of the nanocrystalline shielding sheet. The magnetic breaking mechanism for preparing nanocrystalline shielding sheets in the prior art usually adopts a roller with 1*1 mm grid lines, and the grid roller is used to roll one surface of the Bs nanocrystalline tape to achieve the magnetic breaking treatment of the Bs nanocrystalline tape. However, the existing magnetic breaking mechanism still has the following disadvantages: when using the grid roller to roll the Bs nanocrystalline tape, the pattern presented on the surface of the Bs nanocrystalline tape is very messy (as shown in the attached drawings of the specification), so that the resistance and loss cannot be effectively reduced. Therefore, it is urgent to study a magnetic breaking mechanism for preparing nanocrystalline shielding sheets to solve the above problems. Figure 1 Therefore, it is urgent to study a magnetic breaking mechanism for preparing nanocrystalline shielding sheets to solve the above problems. Summary of the Utility Model
