Abstract
An apparatus for manufacturing a solid electrolytic capacitor includes an anodization part, a polymerization part, a cathode layer formation part, an assembly part, and a molding part. The polymerization part includes a plurality of polymerization baths of a substantially same structure and a conveyance mechanism. In addition the plurality of polymerization baths are placed around the conveyance mechanism within a conveyance range.
Claims20
An apparatus for manufacturing a solid electrolytic capacitor comprising:
- (1) an anodization part for forming a dielectric oxide film on a surface of a porous anode element made of a valve action metal, the anode element embedded therein an anode lead line with one end portion of the anode lead line exposed to an outside;
- (2) a polymerization part for forming a solid electrolytic layer made of an electroconductive polymer on the dielectric oxide film by a chemical oxidation polymerization, and comprising a plurality of polymerization baths of a substantially same structure, and a conveyance mechanism, wherein the plurality of polymerization baths are placed around the conveyance mechanism within a conveyance range;
- (3) a cathode layer formation part for forming a cathode layer on the solid electrolytic layer and providing a capacitor element;
- (4) an assembly part for connecting the anode lead line with an anode terminal and connecting the cathode lead line with a cathode terminal, the anode and cathode terminals being for connecting with an outer circuit;
- and
- (5) a molding part for covering the capacitor element with a covering resin with respective portions of the anode and cathode terminals exposed to an outside.
