Abstract

This invention relates to a manufacturing method for Al electrolyte condensers including: connecting the tongue parts of positive and negative conducting pins with positive and negative foils by riveting and putting the front parts of the initially processed anode and cathode foils at a cylindrical shaft together characterizing in adding two layers of electrolyte paper a and c between the foils and putting the front parts of them at the shaft, adding two layers of electrolyte paper b and d between the cathode foil and an anti-loose adhesive tape and putting the front parts of them at the shaft, starting up the switch of the shaft to wind the anode and cathode foils and electrolyte paper a, b, c and d along with the shaft then to bind them with the anti-loose tape, then dipping them to put them into a tubular Al shell with bottom and sealing the open of the Al shell with rubber plug to get an Al electrolyte condenser.

Description

A kind of manufacturing process of aluminium electrolytic capacitor
Technical field
The present invention relates to a kind of manufacturing process of aluminium electrolytic capacitor, belong to the capacitor manufacturing process technical field.
Background technology
At present, in the existing aluminium electrolytic capacitor production technology, the riveting of the tongue of its positive and negative guide pin thorn is on the positive and negative electrode aluminium foil, because alternating floor electrolytic paper only between the positive and negative aluminium foil, the burr of its cathode foil guide pin tongue contacts with electrolytic paper, and burr may pierce through electrolytic paper and cause short circuit to puncture; The tongue of cathode foil and guide pin links by the thorn riveting in addition, and this place electrochemical reaction will take place and produces a large amount of heat during energising, causes life of product to shorten.
Summary of the invention
The manufacturing process that the purpose of this invention is to provide a kind of rate of finished products height, stable performance, long-life aluminium electrolytic capacitor.
For realizing above purpose, technical scheme of the present invention provides a kind of manufacturing process of aluminium electrolytic capacitor, comprising:
The first step. link together with cathode foil, anode foil respectively by the tongue of thorn riveting positive guide pin, negative guide pin;
Second step. the anode foils of initial processing and Cathode Foil placed columniform rotating shaft place foremost together;
It is characterized in that,
The 3rd step. between anode foils and Cathode Foil, add two-layer a electrolytic paper and c electrolytic paper, a electrolytic paper and c electrolytic paper placed columniform rotating shaft place foremost together;
The 4th step. in Cathode Foil with end and add two-layer electrolytic paper and d electrolytic paper between the loose adhesive tape, b electrolytic paper, d electrolytic paper placed columniform rotating shaft place foremost together;
The 5th step. start the rotating shaft switch, anode foils and Cathode Foil, a electrolytic paper and c electrolytic paper, b electrolytic paper, d electrolytic paper are reeled with rotating shaft for six layers together, extend and covering fully, bundle with ending the pine band again from roll set;
The 6th step. will bundle good aluminium electrolytic capacitor inner core impregnation and be placed in the band bottom tube shape aluminum hull, be aluminium electrolytic capacitor with rubber plug sealed aluminum shell opener.
The present invention is reaching in Cathode Foil and is ending increase one deck electrolytic paper between the loose adhesive tape between anode foils and the Cathode Foil, make becoming of original one deck two-layer, this electrolytic paper has covered positive and negative aluminium foil, prevent that effectively burr from piercing through electrolytic paper and causing switching between the positive and negative paper tinsel, solve Yin Maoci and punctured the capacitor short-circuit puncture that electrolytic paper causes, simultaneously, because of increasing electrolytic paper, reduce the harmful effect that the product heating brings, prolonged life of product.Through test, the short circuit puncture rate that is caused by positive and negative paper tinsel burr is reduced to 10ppm by original 0.3%, prolongs 20%-40% useful life.
Advantage of the present invention is aluminium electrolytic capacitor rate of finished products height, stable performance, the long-life that makes.
Description of drawings
Fig. 1 is a kind of aluminium electrolytic capacitor structural representation.
Embodiment
The invention will be further described below in conjunction with drawings and Examples.
