Description

Technical Field

[0001] This utility model relates to the technical field of corrosion foil, and in particular to a production and processing device for medium and high pressure corrosion foil. Background Technology

[0002] Etched foil is a functional material that forms a porous structure on the surface of high-purity aluminum foil through an electrochemical etching process. Its core function is to significantly increase the specific surface area of ​​the aluminum foil, providing an "electrode energy storage carrier" for aluminum electrolytic capacitors. It is a key component of aluminum electrolytic capacitors, and its performance directly determines the capacitor's capacity, lifespan, and ripple current withstand capability. It is widely used in consumer electronics, industrial control, new energy vehicles, and other fields.

[0003] Precise control of aluminum foil tension is a core factor in determining product quality and production stability. Excessive tension can lead to stretching deformation of the aluminum foil and damage to the etched hole structure; insufficient tension can cause aluminum foil wrinkles and misalignment during transmission.

In this process, the transmission component 4 drives the unwinding roller 2 to rotate, the aluminum foil is released from the unwinding roller 2, and the aluminum foil moves into the corrosion chamber. The corrosion reaction component 6 sprays the corrosion liquid onto the surface of the aluminum foil, so that the corrosion liquid reacts with the surface of the aluminum foil to generate a porous corrosion layer. The cleaning component 7 cleans the residual corrosion liquid on the surface of the aluminum foil, so that the pores on the surface of the aluminum foil are not easy to continue to expand due to the residual liquid. After the reaction is completed, the winding roller 3 winds up the corrosion foil, making it convenient for the staff to carry out the next process. During this process, the tension adjustment component 5 monitors the tension of the aluminum foil in real time, so that the aluminum foil is not prone to stretching and deformation or damage to the etched hole structure due to excessive tension, or wrinkles due to insufficient tension, resulting in spray dead corners and reduced product quality.

When the aluminum foil tension is too high, the aluminum foil pushes up the detection wheel 513 located above. The detection wheel 513 drives the slider 511 to move upward. The slider 511 pulls the lever 514 to rotate counterclockwise. The friction block 515 moves away from the friction disk 517, the damping decreases, the rotational resistance of the damping shaft 516 decreases, the rotational speed of the damping shaft 516 increases, and the damping shaft 516 drives the unwinding roller 2 to rotate through the second gear 519 and the third gear 520.

The slider 511 pushes the lever 514 to rotate clockwise, the friction block 515 moves closer to the friction disk 517, the damping increases, the resistance of the damping shaft 516 increases, the rotation speed of the unwinding roller 2 decreases, the unwinding speed slows down, and the tension rises again.

[0021] In this embodiment, the corrosion reaction assembly 6 includes a storage tank 610, an adjusting tank 611, a first liquid guide pipe 612, a second liquid guide pipe 613, a spray head 614, a rotating shaft 615, a cam 616, a push rod 617, a push plate 618, a return spring 619, and a fourth gear 620. The storage tank 610 is fixedly disposed at the bottom end of the housing 1, and an inlet groove is provided at the top end of the storage tank 610. The adjusting tank 611 is fixedly disposed on the side wall of the housing 1 and located above the storage tank 610. A metal diaphragm is disposed inside the adjusting tank 611. The interior of the adjusting tank 611 is divided into a driving chamber and a reagent chamber.

One end of the second liquid guide pipe 613 is connected to the reagent chamber. The spray head 614 is disposed at the end of the second liquid guide pipe 613 away from the regulating box 611.

In this system, the conveyor chain 416 drives the fourth gear 620 to rotate, and the rotating shaft 615 follows the rotation of the fourth gear 620. The rotating shaft 615 drives the cam 616 to rotate, and the cam 616 periodically pushes the push rod 617 to move closer to the regulating box 611. The return spring 619 is compressed, and at the same time, the push plate 618 squeezes the metal diaphragm, reducing the volume of the reagent chamber of the regulating box 611. This forces the corrosive liquid out from the second liquid guide pipe 613 and sprays it out from the spray head 614. After the cam 616 disengages from the push rod 617, the return spring 619 returns the push rod 617 to its original position, and the volume of the reagent chamber of the regulating box 611 increases, generating negative pressure. This draws the corrosive liquid in the lower cavity of the storage tank 610 into the first liquid guide pipe 612, thereby adjusting the spraying speed of the corrosive liquid according to the moving speed of the aluminum foil.
