Abstract
The invention discloses an adhering molding technology of picking inductance soft magnet oxygen mini-type magnetic jar that mixes adhesive agent into magnetic powder, whisking to equal and taking impact briquetting. It lowers producing cost and realizes automatic manufacturing. It has high yield. And the inductance reaches standard of sintering technology.
Description
Affiliated technical field
The present invention relates to a kind of improvement of miniature inductance magnet ring manufacture craft, this product is applicable to electronic watch, on the small-sized electronic products such as pocket calculating machine, electronic door bell and electronic toy.
Technical background
As everyone knows, the miniature inductance magnet ring is made up of miniature soft magnetic ferrite magnetic jar and magnetic core, their production technology is that magnetic is carried out sintering, grinding again through after the compression forming at present, manufacturing process is very complicated, and because temperature deviation causes shrinkage inconsistent, and the magnetic jar is easy to generate cracking, breakage or metaboly in sintering process, rate of finished products is low, make that the quality of fit between magnetic jar and the magnetic core is poor, leakage flux is bigger, ultra-thin tank skin grinding difficulty is big, the required precision height, and production efficiency is low.
Summary of the invention
Task of the present invention provides a kind of adhesive moulding technique of chip inductor soft magnetic ferrite micro-magnetic tank, it bonds together mutually with magnetic powder and bonding agent, additive, remove sintering circuit from, the quality of fit of magnetic jar and magnetic core is improved, magnetic resistance is little, not only its performance and rate of finished products are significantly increased, and can realize the production automation, without grinding, it can not produce cracking, damaged or distortion yet, have the moulding consistency, its inductance index reaches and adopts the requirement of sintering process production standard.
Task of the present invention is to finish in such a way, at the defective that exists in the magnetic jar sintering process, at first aspect manufacture craft, improve, it adopts the technology of non-sintering, promptly uses bonding method, mixes into bonding agents such as epoxy resin, polyacrylic resin or phenolic resins in the magnetic powder, the back forms composite material by stirring, make bonding ferrite soft magnetic have good material property, use the production equipment of automatic compression forming, realize the automation of producing.
Description of drawings
The present invention is further illustrated below in conjunction with accompanying drawing.
Fig. 1 is chip inductor soft magnetic ferrite micro-magnetic tank technological process of production figure of the present invention.
Embodiment
Can know among the technological process of production figure from figure, the adhesive moulding technique of this chip inductor soft magnetic ferrite micro-magnetic tank is to mix earlier into bonding agent and additive in the functional material magnetic, bonding agent mainly is meant epoxy resin, three kinds in polyacrylic resin and phenolic resins, make powder and various mixed with resin even by stirring again, form composite material, in compacting shape machine, carry out punch forming then, realize the production of automation in enormous quantities, this manufacture craft is owing to adopt the adhesive technology of non-sintering, it does not carry out the grinding program, makes production cost greatly reduce, and rate of finished products greatly improves.
This chip inductor soft magnetic ferrite micro-magnetic tank is produced with adhering method, it is unburned knot, therefore have the dimensional structure of good magnetic permeability, ultra-thin-wall and very high robustness, inductance value reaches the level that adopts sintering process, it also has accurate dimensional uniformity and high Curie temperature point, have the accuracy that cooperates with soft magnet oxidation magnetic core, leakage flux is little.
Claims (1)
1, a kind of adhesive moulding technique of chip inductor soft magnetic ferrite micro-magnetic tank, it is characterized in that: in the functional material magnetic, mix earlier into bonding agent and an amount of additives such as epoxy resin, polyacrylic resin or phenolic resins, by stirring they are mixed, form composite material, in compacting shape machine, carry out punch forming then.
