The invention relates to the technical field of aluminum electrolytic capacitor manufacturing, and provides a novel impregnation process for an aluminum electrolytic capacitor, which comprises the following steps: drying: respectively drying electrolytic paper, a positive electrode foil and a negative electrode foil; carrying out impregnation, i.e., carrying out uniform impregnation on the dried electrolytic paper; conveying, i.e., respectively conveying the impregnated electrolytic paper, the dried positive electrode foil and the dried negative electrode foil to a winding device; and winding,i.e., arranging electrolytic paper between the positive electrode foil and the negative electrode foil, sequentially laminating, and winding the electrolytic paper, the positive electrode foil and the negative electrode foil into a core package through a winding device. The novel impregnation process for the aluminum electrolytic capacitor provided by the invention can integrate winding and impregnation, is simple in preparation process, good in impregnation effect and low in industrialization cost, and is beneficial to improvement of economic benefits and reduction of labor cost.
Description
technical field [0001] The application belongs to the technical field of making aluminum electrolytic capacitors, and more specifically relates to a new process of impregnating aluminum electrolytic capacitors. Background technique [0002] At present, the production process of aluminum electrolytic capacitors is generally to first roll the electrolytic paper, positive electrode foil and negative electrode foil into core packages, and then put the rolled core packages in large quantities into a vacuumed impregnation tank for impregnation. In the actual production process, such an impregnation method is likely to cause uneven impregnation of the electrolyte, and the impregnation time is relatively long, and the core package is soaked in the electrolyte for a long time, which may easily cause deformation and pollution of the lead terminals. At the same time, large-scale impregnation is adopted. After impregnation and before assembly, the impregnated core packs are exposed to t...
