Etching tank for hole forming of etched foil of aluminum electrolytic capacitor

The utility model discloses an aluminum electrolytic capacitor corrosion foil hole-forming corrosion tank, which comprises a tank body, a baffle plate group is fixedly arranged at an electronic aluminum light foil inlet end of the tank body, the baffle plate group comprises a first baffle plate and a second baffle plate, and the first baffle plate and the second baffle plate are arranged in an inverted triangle shape to form a triangular bubble blocking area. The lower end of the bubble blocking area is positioned below the liquid level of the bath liquid; a conveying gap is kept at the contact position of the first baffle and the second baffle. The device is reasonable in design and ingenious in structure and is used for hole-forming processing of the aluminum light foil, the two insulating baffles are reasonably designed, an inverted-triangle-shaped bubble blocking area is formed, and the influence of bubbles on the electronic aluminum light foil in the hole-forming process can be avoided. 本实用新型公开了一种铝电解电容器腐
