Example Embodiment

[0035] Examples:

[0036] This embodiment shows a shredding treatment process of a magnetic material for electromagnetic shielding. The specific steps are as follows:

[0037] S1) Provide a soft magnetic material magnetic sheet, and wind the soft magnetic material magnetic sheet;

[0038] S2) heat-treating the wound magnetic sheet of soft magnetic material;

[0039] S3) Single-sided coating of the soft magnetic material magnetic sheet after the heat treatment;

[0040] S4) Graphically process the uncoated side of the soft magnetic material magnetic sheet by using a pinhole flat pressing block with patterns;

[0041] S5) Gluing the patterned surface;

[0042] S6) Adhere the coated surface of the step S5) to the patterned surface of another piece of soft magnetic material magnetic sheet, laminate it to the required number of layers, and then perform the entire lamination operation. A piece of soft magnetic material is obtained after the steps S1) to S4).

[0043] In step S1), the preparatio...

Abstract

The invention relates to a fragmentation treatment technology of a magnetic material for electromagnetic shielding. The specific steps include: S1) providing a soft magnetic material magnetic sheet, and winding the soft magnetic material magnetic sheet; S2) subjecting the wound soft magnetic material magnetic sheet to heat treatment; S3) performing single-side coating on the heat treated soft magnetic material magnetic sheet; S4) using a patterned pinhole plane pressure block to perform graphical processing on the graphical side of the soft magnetic material magnetic sheet; S5) coating the surface subjected to graphical processing; S6) bonding the coated surface in step 5) to the graphical processed surface of another soft magnetic material magnetic sheet, conducting overlaying to a required number of layers, and then conducting lamination operation on the whole, wherein the another soft magnetic material magnetic sheet is obtained by the S1) to S4).

Description

technical field [0001] The invention relates to the application field of wireless energy transmission and electromagnetic shielding of magnetic materials in power electronic magnetic components. Specifically, it shows a fragmentation treatment process of magnetic materials for electromagnetic shielding. Background technique [0002] In recent years, with the popularization of smart phones, digital cameras, tablet computers and other small portable mobile devices, more and more electronic devices have begun to use wireless charging technology for power supply, which saves a lot of chargers and data lines, and also It solves the problem that the interface of the current electronic equipment does not match, and greatly facilitates people's working and living habits. [0003] Wireless charging technology is a technology that transmits electric energy from the power supply transmitter coil (above 100kHz) to the power receiver coil, and charges the battery of the device. The char...
