Abstract
The invention discloses a Farad level electrolytic capacitor lead sheet hydraulic riveting technology comprising the following steps: rolling core; dipping; drying; riveting; fixing and casing; aging and detection. A riveting step is added when compared with a conventional technology, and lead sheets are integrated so as to reduce gaps between the lead sheets, thus reducing capacitor resistance, and minimizing loss tangent, so a capacitor is high in quality, long in life, shortened in charge and discharge time under a high frequency state, and is low in blast rate.
Description
Technical field
The present invention relates to the processing technology of capacitor, what be specifically related to is a kind of farad level electrolytic capacitor leader hydraulic pressure thorn riveter skill.
Background technology
Along with the develop rapidly of modern science and technology and auto industry and consumer electronics, people require more and more higher to the tonequality perfection of car sounder, home audio.Adopt that farad-grade aluminium electrolytic capacitor can promote that supply voltage is highly stable, big current abrupt release, decoupling, noise control, reduce low-frequency distortion etc.Its basic role improves power quality, strengthening filter function and decoupling, suppresses noise and various electromagnetic interference, improves power of bursting.
The both positive and negative polarity of farad-grade aluminium electrolytic capacitor forms by organizing leader more, but at present, many groups leader on the market directly welds with cover plate, and the gap often organized between leader is very large, cause both positive and negative polarity self-resistance large, thus loss tangent is high.Therefore there is following problem in capacitor:
(1) capacitor resistance is high, and loss tangent is large;
(2) life-span of capacitor is short;
(3) under high frequency state, capacitor easily explodes;
(4) under high frequency state, the discharge and recharge time of capacitor is long.
Summary of the invention
The object of the invention is to the above problem overcoming prior art existence, provide a kind of farad level electrolytic capacitor leader hydraulic pressure to sting riveter skill, leader riveted will be organized integral more, reduce the gap between leader.
For realizing above-mentioned technical purpose, reach above-mentioned technique effect, the present invention is achieved through the following technical solutions:
A kind of farad level electrolytic capacitor leader hydraulic pressure thorn riveter skill, comprises the following steps:
Step 1) core: anode foils, electrolyte are wound into core bag together with Cathode Foil, Cathode Foil is outwardly and encase electrolyte;
Step 2) dipping: core bag is immersed in forming liquid;
Step 3) is dry: taken out by the core bag after dipping, carry out drying by drying machine;
Step 4) thorn riveting: use thorn riveting mould to carry out thorn riveting;
Step 5) is fixed, and enters shell envelope: be packaged into by core in aluminum hull, seal with rubber stopper;
Step 6) is aging, detects: the product after sealing is applied direct voltage by the rated voltage of 60%, 80%, 100%, 120% respectively, carries out segmentation burin-in process.
As what optimize, the forming liquid in described step 2 is ammonium dihydrogen phosphate, and concentration is 1mg/ml-3mg/ml.
As what optimize, the dip time of described step 2 is 30 minutes-40 minutes.
As what optimize, the baking temperature in described step 3 is 200-300 DEG C, and drying time is 5-10 minute.
As what optimize, thorn riveting mould in described step 4 comprises frame, described frame top is provided with guide pad, is provided with top board, upper cushion block, lower cushion block and lower platen from top to bottom successively in described frame, is provided with contiguous block and force-applying piece between described upper cushion block and described lower cushion block.
The invention has the beneficial effects as follows:
Thorn riveting step that the present invention is more than traditional handicraft, leader is integrated, reduce the gap between leader, thus the resistance of capacitor diminishes, loss tangent diminishes, and therefore capacitor quality is high, life-span is long, time shorten, the rate of explosion of discharge and recharge under high frequency state are low, instead of the use of storage battery at wind power generation, solar power generation, automobile industry aluminum cell capacitor gradually, not only energy-conservation but also environmental protection.
