Embodiment 1

[0022] A processing technology of a solid electrolyte aluminum electrolytic capacitor is carried out according to the following steps:

[0023] 1) Rivet the positive guide pin on the anode foil, and rivet the negative guide pin on the cathode foil. When riveting, the foil is placed in the middle of the flat plate of the guide pin, so that the reserves on both sides are equal, and the electrolytic paper is sandwiched between the two guide pins. , the electrolytic paper is wider than the electrode foil, and the two sides of the winding exceed the electrode foil. Electrolytic paper covers the junction of the round rod part and the flat part of the guide pin;

[0024] 2) Winding with a winding machine, the cathode foil is rolled more, so that the cathode foil wraps the entire core package, and then wraps it with high-temperature adhesive tape to fix it tightly;

[0025] 3) Install the rubber cover for sealing on the core bag;

[0026] 4) The core pack is immersed in the ...

Abstract

The invention discloses a processing technology of an aluminum electrolytic capacitor for solid electrolytes. The processing technology includes the steps of: riveting a positive guide pin on an anode foil, and riveting a negative guide pin on a cathode foil; coiling by a coiler, coiling more cathode foil to cover the whole core cladding, and then winding with a high-temperature resistant tape for clinging and fixing; installing a rubber cover for sealing on the core cladding; steeping the core cladding into forming agent for repairing, taking out and then soaking up redundant moisture; performing carbonization treatment on the repaired core cladding; repeating the steps of steeping the core cladding and carbonizing; further steeping the core cladding into the forming agent for repairing, after formation putting into deionized water for cleaning, wherein the electrical resistivity of the water is more than 2M; impregnating by monomer oxidizing agent; after impregnation, polymerizing, thermally processing, finally packaging into an aluminum shell, sealing, aging, and thereby obtaining the finished product. According to the unique impregnating method and technical parameters in impregnation provided by the invention, the produced solid capacitor is stable in quality and low in rejection rate.

Description

technical field [0001] The invention relates to the technical field of preparation of electrolytic capacitors, in particular to a processing technology of solid electrolyte aluminum electrolytic capacitors. Background technique [0002] The replacement products of traditional liquid capacitors for solid capacitor operation have their unique and excellent characteristics. At present, they are all used in the production process. The positive guide pin is riveted on the anode foil, and the negative guide pin is riveted on the cathode foil; Machine winding, more rolls of cathode foil, let the cathode foil wrap the entire core package, and then wrap around it with high-temperature adhesive tape to fix it tightly; install the sealing rubber cover on the core package; immerse the core package in the chemical solution for repairing, After taking it out, absorb the excess water; carry out carbonization treatment on the repaired core bag; repeat the immersion and carbonization of the...
