Abstract

The invention provides an SMD inductance device with a magnetic rubber coating iron core and a processing technology thereof. The SMD inductance device with the magnetic rubber coating iron core comprises a substrate, one end of the substrate is plated with a silver paste layer, sunk parts of the substrate and the silver paste layer are wound with enamelled copper wires which are plated with a protection coat, and the protection coat is composed of plastic BASE materials. According to the SMD inductance device with the magnetic rubber coating iron core and the processing technology thereof, on one hand, the good effect of protecting the enamelled wires is achieved; on the other hand, a good induction effect in the actual operation is achieved; damage to electronic products caused by an instantaneous excessive current can be prevented.

Description

A kind of SMD inductance device with magnetic gel coating iron core and processing technology thereof

Technical field

The present invention relates to inductance component field, specifically a kind of SMD inductance device with magnetic gel coating iron core and processing technology thereof.

Background technology

Existing induction structure, mainly welded by the artificial joint portion soldering to coil and terminal, this operator scheme is high especially for the requirement of personnel in welding process on the one hand, personnel easily make mistakes in operation, easily there are substandard products, operating efficiency is low, on the other hand, the cost of enterprise is added with soldering, be unfavorable for the enlarged reproduction of enterprise, existing SMD inductance device magnetic core is mostly directly outside exposed, lack corresponding protection, cause the thermal shock resistance of inductance, moisture resistance properties and shock resistance poor, the use in practical operation cannot be met.

Summary of the invention

The invention provides a kind of SMD inductance device with magnetic gel coating iron core and processing technology thereof; there is the effect of good protective paint envelope curve on the one hand; on the other hand there is in practical operation good inductive effects, immediate current can be prevented excessive, cause the damage of electronic product.

A kind of SMD inductance device with magnetic gel coating iron core of the present invention, comprise matrix, one end of matrix is coated with silver slurry layer, and the depressed area of matrix and silver slurry layer is wound with enamel covered wire, and enamel covered wire is coated with protective layer, and described protective layer is made up of plastic cement BASE material.

Further improvement, described matrix is that carbonyl iron dust material is formed.

Further improvement, described matrix surface is coated with and has crossed nickel and tin.

Present invention also offers a kind of SMD inductance processing technology with magnetic gel coating iron core and comprise the following steps of carrying out successively:

1) coiling spot welding: pour matrix into vibrating disk, is vibrated by vibrating disk, allows matrix arrange according to certain position, enter the bar that directly shakes directly to shake, when the bar that directly shakes puts in place, differentiate there is material, pan feeding arm starts pan feeding, enter to expect capstan head jaw, turret rotated starts coiling to winding position, and after coiling, capstan head starts spot welding, tangent line is carried out, rewinding after tangent line after spot welding.

2) baking paint: by the matrix of coiling, some postwelding, pour vibrating disk into, vibrated by vibrating disk, allow coiling, some postwelding matrix arrange according to certain position, enter the bar that directly shakes after arrangement directly to shake, when the bar that directly shakes puts in place, differentiate there is material, enter material strip and start pan feeding, by turret rotated, correct the position of product, then gluing by turret rotated, after gluing, capstan head starts rewinding, and the matrix after gluing is put into oven cooking cycle by material collecting arm.

3) examine outward: by professional, the product after baking is tested, the outward appearance of inspection product, comprise breakage, secretly split, be stained with foreign matter, leak copper cash, glue overflows and failure welding.

4) testing package: the qualified products after outer inspection are put into vibrating disk, is vibrated by vibrating disk, allows matrix arrange according to certain position, enter the bar that directly shakes directly to shake, when the bar that directly shakes puts in place, differentiate there is material, suction arm starts suction, capstan head after suction, start to correct, after correcting, capstan head starts to test RDC, then capstan head starts to test inductance value, by capstan head, underproof product is blown into bad product box, qualified product is packed.

5) band inspection: tested for the product after packaging by professional, the outward appearance of inspection examination and test of products product, comprises breakage, secretly splits, is stained with foreign matter, leaks copper cash, glue overflows and failure welding.

6) put in storage: the product that band inspection is qualified, directly put in storage after QC quality control's secondary check.

Beneficial effect of the present invention is: the effect on the one hand with good protective paint envelope curve, has good inductive effects on the other hand, immediate current can be prevented excessive, cause the damage of electronic product in practical operation.
