Electrode foil formation device

Abstract

The invention discloses an electrode foil formation device which comprises a formation tank and a formation frame, and is characterized in that electrolyte is filled into the formation tank, the formation frame is immersed in the electrolyte of the formation tank, electrode foil passes through the electrolyte of the tank along an S-shaped path via the formation frame to be processed, a plurality of circulating pipelines extending to the bottom from the top of the formation tank are arranged on the wall of the formation tank, the circulating pipelines are provided with a plurality of circulating holes from top to bottom, the bottom of the formation tank is provided with a circulating outlet and connected with a circulating pump, and then the circulating pump is connected with the circulating pipelines. The electrode foil formation device can effectively control the temperature difference of the electrolyte at each height level in the formation tank, and the circulation of the electrolyte in the formation tank is changed to be great, thus increasing the uniformity of the concentration and temperature of the electrolyte in the formation tank, improving the electrode foil processing quality, ensuring the uniformity of an oxidation film on the surface of the electrode foil, and guaranteeing the continuity and stability of production.

Description

technical field [0001] The invention relates to the technical field of electrode foil production, in particular to an electrode foil formation device. Background technique [0002] Aluminum electrolytic capacitors are an indispensable part of the electronics industry. With the increase of electronic products, the demand for aluminum electrolytic capacitors is also increasing. The formation of aluminum foil is one of the key processes in the manufacture of aluminum electrolytic capacitors. The formation of aluminum foil is to use the electrochemical principle to anodize the aluminum foil to combine the oxygen atoms in the water with the aluminum atoms, thereby forming an oxide film dielectric layer on the surface of the aluminum foil that can withstand a specific voltage. In the production stage, electronic aluminum foil is high-purity aluminum foil, which is made of refined aluminum (high-purity aluminum) aluminum ingots that are hot-rolled into aluminum sheets, and then fur...
