Problems solved by technology

Due to the low magnetic energy stored in the unit volume of ferrite, the saturation magnetization is also low (usually only 1 / 3 to 1 / 5 of pure iron), which limits its use in low-frequency strong electricity and high-voltage applications that require higher magnetic energy density. Applications in the high-power field, but at present, ferrite can’t make glue-free areas in one-sided laser, which can’t meet the needs of some customers

Abstract

The invention relates to a method for producing ferrite non-adhesive zones. The method comprises the following steps: 1) an auxiliary material is fixed and placed on a die cutting fixture, and a die cutting knife is used for cutting the auxiliary material into multiple zones to be lasered whose shapes are matched with the shapes of the non-adhesive zones; 2) the cut auxiliary material and ferrite whose non-adhesive zones are to be manufactured are mutually bonded, in order to roll and remove bubbles; d) after bonding, the ferrite is fixed on a laser fixture through location holes and screws, a laser machine is used for carrying out laser, waste is discharged, and the ferrite is taken out; 4) after laser, the ferrite is cut and fixed, and finally the ferrite finished product containing the non-adhesive zones is produced. Compared with the prior art, the method can fill blanks in the industry, and has the advantages of simple operation, improved efficiency, and the like.

Description

technical field [0001] The invention relates to the field of processing and manufacturing, in particular to a method for making a ferrite glue-free area. Background technique [0002] Ferrite is a metal oxide with ferromagnetic properties. In terms of electrical properties, the resistivity of ferrite is much larger than that of metal and alloy magnetic materials, and it also has higher dielectric properties. The magnetic properties of ferrite are also shown to have higher magnetic permeability at high frequencies. Therefore, ferrite has become a widely used non-metallic magnetic material in the field of high frequency and weak current. Due to the low magnetic energy stored in the unit volume of ferrite, the saturation magnetization is also low (usually only 1 / 3 to 1 / 5 of pure iron), which limits its use in low-frequency strong electricity and high-voltage applications that require higher magnetic energy density. Applications in the high-power field, but at present, ferrit...
