Description
Technical field
The invention belongs to capacitor manufacturing process technical field, particularly relate to the system of a kind of liquid aluminum electrolytic capacitor
Make method.
Background technology
Aluminium electrolutic capacitor basic role in electronic circuit is typically summarised as: logical exchange, resistance direct current, have filtering,
Bypass, coupling and the function of fast charging and discharging, and have that volume is little, store electricity is big, cost performance is high characteristic.Along with modern section
The progress of skill improves constantly with capacitor performance, aluminium electrolutic capacitor be widely used to consumption electronic product, communication products,
Computer and perimeter product, new forms of energy, Automated condtrol, auto industry, photovoltaic, high-speed railway and aviation and military equipment
Deng.
The production technology of original liquid aluminum electrolytic capacitor is: hack → follow closely volume → drying → impregnation → de-liquid → assembling →
Sleeve pipe → test → packaging, the product that completes needs nine operations to complete, has following defects that
One is that owing to having adsorbed liquid electrolyte, its structural strength can reduce, at follow-up set after core bag impregnates in the electrolytic solution
Plug, encapsulation process are easily subject to extruding, core bag are caused damage and then affects the performance of product；
Two is before core wraps in set plug, need to carry out drying → be impregnated with → de-liquid → vibrating disk etc. is to be assembled, and vibrating disk etc. is to be installed
Be difficult to control between timing, then to expose the time in atmosphere longer for green sand core bag, causes green sand core bag to absorb the moisture content in air and sky
Other impurity in gas, greatly affect the life-span of product；
Three is that green sand core wraps in vibration processes, and electrolyte has drippage or the problem of volatilization, the then content of electrolyte between core bag
There is deviation, and longer with a batch of first finished product and last finishing room interval, easily cause between product
There is bigger discordance；
Four is that green sand core wraps in vibration processes, is easily shaken brokenly after electrolytic paper impregnation, and product fraction defective is high, will also result in product
The deterioration of energy, the lost of life；
Five be capacitor when specifically applying, as high temperature reflux weld (about 260 DEG C), owing to capacitor processing procedure exposing in atmosphere
Long period, absorbing the moisture content in air, and too much moisture content is at high temperature heated, boiling becomes steam, and disequilibrium is interior
Portion's gas flow increases to the most then capacitor and the drum end easily occurs, and causes capacitor to lose original function, even results in expansion
Explosion.
Summary of the invention
The technical problem to be solved is the defect overcoming above-mentioned prior art, it is provided that a kind of liquid aluminium electrolysis electricity
The manufacture method of container, plug is first assemblied in the core not being impregnated with and wraps, then carry out impregnation process, greatly reduces green sand core bag by it
Absorb the probability of moisture in air, it is ensured that it is the most quick-fried that capacitor will not occur the drum end to expand in the hot environment of subsequent applications
The problem such as split, it is thus achieved that a kind of high temperature resistant, life-span length, reliability high and concordance is good liquid aluminium electrolysis condenser, this method work
Skill is simple, low cost, not only improves work efficiency and the most effectively reduces the fraction defective of product.
The technical problem to be solved is achieved by the following technical programs:
A kind of manufacture method of liquid aluminum electrolytic capacitor, it comprises the following steps: plug is assemblied in the core not being impregnated with and wraps,
Then impregnation processes, and finally enters aluminum hull sealing.
Further, described impregnation processes is to immerse in electrolyte by the core bag being cased with plug or electrolyte is injected into set
Have in the core bag of plug.
Further, described the step that the core bag being cased with plug immerses in electrolyte is specifically included following steps: immerse
Electrolyte is impregnated with, and then takes off liquid.
Further, described immersion electrolyte carries out impregnation for be impregnated with under vacuum conditions.
Further, the described step being injected into by electrolyte in the core bag being cased with plug specifically includes following steps:
Normal pressure injection electrolyte, then moves in confined space, last evacuation；
Or,
Evacuation, then injects electrolyte；
Or,
Normal pressure injection electrolyte, evacuation, then pressurizes；Wherein, evacuation → pressurization steps at least circulates 1 time；
Or,
Evacuation, injects electrolyte, pressurization.Preferably, also include at least circulating 1 evacuation → add after described pressurization steps
Pressure step.
Further, described in enter aluminum hull sealing after further comprising the steps of: burn-in test, wrap after test passes
Dress.
There is advantages that
(1) core bag first overlaps plug, then is impregnated with, encapsulates, and compared with traditional first impregnation, then overlaps the technique of plug, encapsulation, and impregnation processes
The most directly enter the time that the core bag after aluminum hull greatly reduces impregnation exposes in atmosphere, i.e. decrease green sand core bag by air
Absorb moisture and the possibility being easily polluted by the external foreign matters, greatly shorten with a batch of first finished product and last finishing room simultaneously
Interval so that be impregnated with the amount of electrolyte between product individuality almost without deviation, the consistency of performance between product individuality simultaneously
Also it is improved significantly, improves conforming product rate and work efficiency；
(2) capacitor that this method prepares is under hot environment (higher than 135 DEG C), owing to during processing procedure, green sand core bag is seldom or base
Originally being not exposed in air the most not absorb the moisture content in air, capacitor is essentially without generation the most in high temperature environments
The drum end, expands the problem even burst, it is ensured that the stability under the high temperature of capacitor, improves product high-temperature stability, product quality
And increase the service life；
(3) assembling of plug is wrapped and is carried out not being impregnated with core, i.e. avoids green sand core bag due to absorption electrolyte structural strength
Reduce and make to be vulnerable to the problems such as crush injury during assembling；In core bag vibration processes before plug assembling, owing to being not to be impregnated with core
, there is not the problem of electrolyte drippage or volatilization to ensure the concordance of electrolyte content between core bag, it also avoid green sand core in bag
The problem that in bag, electrolytic paper is easily shaken brokenly, reduces the fraction defective of product, also avoids the performance degradation problems that product is recessive；
(4) use electrolyte to inject the technique of core bag, decrease de-liquid operation after core bag immerses electrolyte, it is to avoid centrifuge takes off liquid
Technique easily causes pin inconsistent etc. by the electrolyte content getting rid of askew, the mutual collsion damage of electrolytic paper and diverse location
Problem, improves product quality further and increases the service life.
