Abstract
Provided is a production process for a capacitor. Aging and electrical property tests of a core after impregnation are conducted. Compared with the conventional step of packaging and then aging, according to the production process, aging can be realized with high current without packaging, the aging time is greatly saved, the phenomenon of electrolysis appears at the internal part of the core during high-current aging, generated hydrogen can be directly discharged, the bulging or even explosion of a shell in the conventional aging process can be prevented, the electrical property test is conducted after aging, unqualified cores are directly discarded, rubber plugs and shells in the subsequent process can be saved, and the cost of enterprises can be greatly reduced.
Description
Technical field
The present invention relates to a kind of production technology of capacitor.
Background technology
Capacitor is one of a large amount of electronic component used in electronic equipment, be widely used in circuit every straight-through friendship, coupling, bypass, filtering, resonant tank, power conversion, the aspects such as control.Along with making rapid progress of electronic information technology, the update speed goes of digital electronic goods is fast, based on the consumer electronics product volume of production and marketing sustainable growth of the products such as panel TV (LCD and PDP), notebook computer, digital camera, capacitor industry has been driven to increase.Capacitor needs to carry out aging after group grain, existing is all the electric capacity produced is put into ageing oven unification to carry out aging, this aging equipment is bulky, ageing time is general all more than 20 hours, again electric performance test is carried out to capacitor after aging, wherein underproof product needed is scrapped, and the situation that simultaneously quick-fried shell easily occurs capacitor in the middle of aging process has an impact to production.
Summary of the invention
The technical problem to be solved in the present invention overcomes the deficiencies in the prior art, provides the capacitor production technology that a kind of ageing time is short, save material.
For solving the problems of the technologies described above, the technical scheme that the present invention proposes is: a kind of production technology of capacitor, comprise the following steps: 1, a kind of production technology of capacitor, is characterized in that: comprise the following steps: 1) cut: cathode foil, anode foil, electrolytic paper are cut into the coiled material needing width;
2) electrode draws the assembling of paper tinsel: positive pole is drawn paper tinsel by riveting or colding pressing riveting in cathode foil, negative pole is drawn paper tinsel by riveting or colding pressing riveting in anode foil;
3) reel: by positive and negative electrode paper tinsel and electrolytic paper staggered floor stacked after roll into core bag, core body outer peripheral face by gummed paper sealing bundle
Tie up;
4) impregnation: temperature 30-80 DEG C, above-mentioned core bag is put into electrolyte under the environment of pressure 5-10kg and floods 6-8 hour;
5) aging: the capacitor before dress shell to be put into opening ageing machine and carries out aging, through following process in opening ageing machine
A: room temperature boost phase, rose to 6.3-600V by voltage by 0V in 10 minutes, and electric current is: 0.6-0.8A,
B: room temperature constant-voltage phase: voltage remains unchanged in 10 minutes, and electric current is down to below 0.02A by 0.5-0.8A;
6) electric performance test: carry out electric performance test by completing aging core bag;
7) shell is filled: load in shell by aging for impregnation good core bag by the vertical machine of group;
8) valve, encapsulation is played: pressure port pressure valve air gun being squeezed into cover plate; Core bag good for impregnation is mixed plug, encapsulation
In aluminum hull, then by mechanical crimp suitable for reading for aluminum hull, and on cover plate, rubber forms the capacitor of sealing;
9) cleaning, drying: cleaning shell, and dry;
10) sleeve pipe: at the outer surface cover one deck hot shortness insulating barrier of aluminium shell of capacitor;
11) packaging is detected: with carton etc., capacitor is packed after having detected outward appearance.
Compared with prior art, the invention has the advantages that: capacitor production technology of the present invention carries out aging and electric performance test to core bag after impregnation; With after conventional package carry out aging compared with, the present invention does not carry out encapsulation and can carry out agingly greatly saving ageing time with big current when aging, when big current is aging, core bag inside there will be the phenomenon of electrolysis, and the hydrogen of generation directly can be discharged and shell bulge even will be exploded as traditional aging technique.And then carry out electric performance test after simultaneously the present invention is aging, underproof core bag is directly scrapped process, so just can save the cost that the rubber stopper of subsequent handling and shell can save enterprise greatly.
