Description

Technical Field

[0001] The invention relates to the technical field of electrode foil processing, in particular to an etching device for electrode foil processing and a use method thereof. Background Art

[0002] Electrode foil is a key material for manufacturing aluminum electrolytic capacitors. With the continuous expansion of the market for large-scale high-power electronic equipment, the demand for various high-voltage and large-capacity electrolytic capacitors has increased sharply. The basic principle of increasing the capacitance of electrode foil is to use corrosive liquid to electrochemically generate and expand holes on the surface of electrode foil to increase the surface area of ​​electrode foil.

[0003] At present, when the electrode foil corrosion device is used, the electrode foil is immersed in the interior of the corrosion device. After the electrode foil is completely immersed in the interior of the corrosion device, the electrode foil needs to be pulled to move inside the corrosion device. However, the electrode foil itself is relatively soft. When the electrode foil enters the interior of the corrosion device, it is easy to be squeezed by the corrosion solution and stacked together, so that the corrosion solution cannot be evenly applied to the surface of the electrode foil, affecting the corrosion treatment quality of the electrode foil.

[0021] When the bending rod of the present invention moves upward, the connection between the rotating ring and the vertical plate pulls the connecting rod upward; when the connecting rod moves upward, the push rod is pulled upward by the inclined plate; when the connecting rod moves downward, the push rod is pushed by the inclined plate to move inside the corrosion rack, and the corrosion solution inside the corrosion rack is stirred by the push rod to avoid condensation of the corrosion solution and poor coating effect.
