1. a kind of manufacture method of polymer solid aluminum electrolytic capacitor, the polymer solid aluminum electrolytic capacitor include aluminum hull,The core bag that is arranged in the aluminum hull, be arranged on the Jiao Gai being tightly connected at the top of the core bag and with the aluminum hull, positive terminal,Negative terminal, the core bag include cathode foil, anode foil, the electrolytic paper that is arranged between the cathode foil and the anode foil withAnd polymer dielectric, the positive terminal is positioned at one end of the core bag and is riveted in the cathode foil, described negative poleTerminal is connected with the bottom of the aluminum hull, and the anode foil is connected by conducting resinl with the aluminum hull, described manufacture methodThe step of winding including carrying out successively forms core bag, carburising step, chemical conversion step, impregnation step, heating polymerization procedure, encapsulationStep and Aging Step, wherein the winding core bag step is:

  • Positive terminal is connected on the one end of cathode foil, thenElectrolytic paper is intervened between cathode foil and anode foil, core bag is wound into, wherein anode foil exceeds cathode foil described in gained core bagWith electrolytic paper and it is exposed,It is characterized in that:

    Described chemical conversion step is:

    First the core bag is put into the electrolytic bath with forming liquid, then by coreThe positive terminal of bag is electrically connected with being melted into the positive pole of power supply so that chemical conversion positive source is connected with cathode foil;

    Simultaneously by core bagThe exposed parts of anode foil are electrically connected with being melted into the negative pole of power supply so that chemical conversion power cathode is connected with anode foil, finally opensPower supply is melted into, while the cathode foil and anode foil to core bag are powered, is applied the voltage in cathode foil and anode foil;

    Described encapsulation step is:

    Bottom is connected with the inner bottom surface of the aluminum hull of negative terminal and coats conducting resinl, then willCore bag is positioned in aluminum hull by Jiao Gai and the exposed parts of the anode foil of core bag are located at the top of conducting resinl, and then heating makesConductive adhesive curing so that negative terminal can be electrically connected with the exposed parts of anode foil by conducting resinl and aluminum hull, then willAluminum hull is sealed with the Jiao Gai forms sealed by rolling, that is, completes encapsulation.
