The invention relates to the field of electrode foil, and discloses a current sharing control device and method for formation of corroded aluminum foil. The current sharing control device for formation of the corroded aluminum foil comprises a rack; a guide assembly, a conductive roller rotatably installed on the rack, and a conductive frame which is installed on the rack and connected with a negative electrode of a formation power supply are sequentially arranged on the rack; the conductive roller is connected with a positive electrode of the formation power supply, and the bottom end of the conductive frame extends into formation liquid in a formation tank; and an electric adjusting assembly used for adjusting vertical lifting of the conductive roller is installed on the rack, a current detection module connected between the conductive roller and the formation power source and a controller electrically connected with the current detection module are further arranged on the rack, the current detection module detects current signals, and transmits the current signals to the controller, and the controller is used for driving the electric adjusting assembly according to change of the received current signals. The current sharing control device and method for formation of the corroded aluminum foil have the effect of stabilizing currents during electrolytic formation of the aluminum foil.

Description

technical field [0001] The present application relates to the field of electrode foils, in particular to a current sharing control device and method for forming corroded aluminum foils. Background technique [0002] At present, in the production process of anode foil for aluminum electrolytic capacitors, in order to expand its effective surface area and increase the electrostatic capacity per unit area, electrochemical reactions are generally used to corrode the surface of the aluminum foil, and then the corroded aluminum foil is then chemically formed on the aluminum foil. Oxide films with different thicknesses resistant to different voltage levels are formed on the surface of the battery. [0003] Such as figure 1 As shown, in the formation process of the aluminum foil 05, the aluminum foil 05 passes through the conductive roller 3 and the guide roller assembly through the chemical formation tank 01, the chemical conversion tank 01 is provided with the chemical conversion...

Problems solved by technology

[0004] However, in view of the related technologies mentioned above, the inventor believes that: in the actual production process, due to the different connection conditions of the power connection equipment in the plant, the voltage of the formation power supply corresponding to the formation tank may be unstable, which in turn causes the actual formation power supply to be unstable. The current and voltage are unstable, which in turn affects the electrolytic formation of aluminum foil
