Description

Technical Field

[0001] This utility model relates to the field of electroforming foil production technology, and more specifically to a surface pretreatment device for electroforming foil production. Background Technology

[0002] As a core material for aluminum electrolytic capacitors and tantalum electrolytic capacitors, the quality of its electrical performance directly determines the capacitor's capacitance, loss tangent, leakage current, and even its service life. In order to form a high dielectric constant oxide film dielectric layer on the surface of the metal foil, a crucial formation process must be performed.

[0003] However, surface pretreatment of the foil is an essential preceding process before formation. Its purpose is to thoroughly remove residual grease, contaminants, and natural oxide layers from the foil rolling process. More importantly, it forms a uniform, dense, and specific morphological pit structure on the foil surface through electrochemical etching. This microstructure formed by pretreatment is the cornerstone for the subsequent growth of a high-quality oxide film. Its uniformity and quality are directly related to the specific capacitance, breakdown voltage, and performance consistency of the final formed foil.

[0004] Currently, when removing residual contaminants during surface treatment, the contaminants are removed by contacting the cleaning roller with the coated foil material. However, cleaning through physical contact alone cannot remove some stubborn oil stains. Furthermore, since the coated foil material has different thicknesses, the current cleaning rollers cannot be freely adjusted in distance, resulting in poor applicability. Summary of the Invention

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a surface pretreatment device for electrolytic foil production to solve the problems existing in the background art.

[0006] This utility model provides the following technical solution: a surface pretreatment device for electrolytic foil production, including a feeding roller, electrolytic foil raw material surrounding the side of the feeding roller, a receiving roller movably connected to the inside of the electrolytic foil raw material away from the feeding roller, a spraying mechanism provided on the side of the electrolytic foil raw material near the feeding roller, and a cleaning mechanism provided on the side of the electrolytic foil raw material near the receiving roller; the spraying mechanism includes a supporting fixed plate, an upper connecting plate fixedly connected to the top of the side of the fixed plate, an upper flow channel plate fixedly connected to the side of the upper connecting plate, an upper water inlet pipe fixedly connected to the top of the upper flow channel plate, and an upper spray head fixedly connected to the bottom of the upper flow channel plate.

[0007] Furthermore, the spraying mechanism sprays cleaning liquid above and below the formed foil material, and the cleaning mechanism cleans the above and below the formed foil material. Support plates are fixedly connected to both sides of the feeding roller and the receiving roller.

[0008] Furthermore, a lower connecting plate is fixedly connected to the middle of the side of the fixed plate near the upper connecting plate, a lower flow channel plate is fixedly connected to the side of the lower connecting plate away from the fixed plate, a lower nozzle is fixedly connected to the top of the lower flow channel plate, and a lower water inlet pipe is fixedly connected to the bottom of the lower flow channel plate. The chemically formed foil raw material is located between the upper nozzle and the lower nozzle.

[0009] Furthermore, the cleaning mechanism includes a first fixed block for support, a bidirectional screw is movably connected to the top of the first fixed block, an adjusting wheel is fixedly connected to the top of the bidirectional screw, a mirror-symmetrical threaded groove is opened on the side of the bidirectional screw, and an upper moving plate and a lower moving plate are threadedly connected to the side of the threaded groove of the bidirectional screw, and the upper moving plate and the lower moving plate move closer to each other or further away from each other.

[0010] Furthermore, an upper cleaning block is fixedly connected to the bottom end of the upper moving plate, and a lower cleaning block is fixedly connected to the top end of the lower moving plate. Both the upper and lower cleaning blocks are made of rubber, and the chemically formed foil raw material is located between the upper cleaning block and the lower moving plate.

[0011] Furthermore, both the upper and lower moving plates are movably connected to limit rods on the sides away from the bidirectional screw. Limiting grooves adapted to the limit rods are opened inside the upper and lower moving plates. A second fixing block is fixedly connected to the bottom end of the limit rod.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] 1. This utility model, by comprising an upper flow channel plate, an upper nozzle, a lower flow channel plate, and a lower nozzle, allows for the cleaning of electrolytic foil materials. Water and cleaning fluid are introduced into the upper water inlet pipe. The introduced liquid flows within the upper flow channel plate, and is then sprayed onto the top of the electrolytic foil material by the upper nozzle. Simultaneously, water and cleaning fluid are introduced into the lower water inlet pipe. The introduced liquid flows within the lower flow channel plate and is then sprayed onto the bottom of the electrolytic foil material by the lower nozzle. This ensures that cleaning fluid is sprayed both above and below the electrolytic foil material, effectively removing stubborn oil stains and guaranteeing a cleaning effect.

[0014] 2. This utility model comprises an upper moving plate, an upper cleaning block, a lower moving plate, and a lower cleaning block. After the forming foil material is sprayed with cleaning liquid, the adjusting wheel is rotated. When the adjusting wheel rotates, it drives the bidirectional screw to rotate. When the bidirectional screw rotates, the upper moving plate and the lower moving plate move closer to each other or further away from each other, thereby changing the distance between the upper cleaning block and the lower cleaning block. This adjusts the pressure of the upper cleaning block and the lower cleaning block on the forming foil material moving between them, thereby effectively cleaning the surface of forming foil materials of different thicknesses.

[0020] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0021] Reference Figure 1 This utility model provides a surface pretreatment device for the production of electrolytic foil, including a feeding roller 1, an electrolytic foil raw material 4 surrounding the side of the feeding roller 1, a receiving roller 2 movably connected to the inside of the electrolytic foil raw material 4 away from the feeding roller 1, a spraying mechanism 5 provided on the side of the electrolytic foil raw material 4 near the feeding roller 1, and a cleaning mechanism 6 provided on the side of the electrolytic foil raw material 4 near the receiving roller 2. The spraying mechanism 5 sprays cleaning liquid above and below the electrolytic foil raw material 4, and the cleaning mechanism 6 cleans the top and bottom of the electrolytic foil raw material 4. Support plates 3 are fixedly connected to both sides of the feeding roller 1 and the receiving roller 2.

[0022] In this embodiment, the spraying mechanism 5 sprays cleaning liquid above and below the forming foil material 4, and the cleaning mechanism 6 cleans the above and below the forming foil material 4 after the cleaning liquid has been sprayed, ensuring the cleaning effect and removing stubborn oil stains. The support plate 3 provides stable support for the feeding roller 1 and the receiving roller 2.

[0023] Reference Figure 2 and Figure 3The spraying mechanism 5 includes a fixed plate 501 for support. An upper connecting plate 502 is fixedly connected to the top of the side of the fixed plate 501. An upper flow channel plate 503 is fixedly connected to the side of the upper connecting plate 502. An upper water inlet pipe 505 is fixedly connected to the top of the upper flow channel plate 503. An upper nozzle 504 is fixedly connected to the bottom of the upper flow channel plate 503. A lower connecting plate 506 is fixedly connected to the middle of the side of the fixed plate 501 near the upper connecting plate 502. A lower flow channel plate 507 is fixedly connected to the side of the lower connecting plate 506 away from the fixed plate 501. A lower nozzle 508 is fixedly connected to the top of the lower flow channel plate 507. A lower water inlet pipe 509 is fixedly connected to the bottom of the lower flow channel plate 507. The chemically formed foil raw material 4 is located between the upper nozzle 504 and the lower nozzle 508.

[0024] In this embodiment, the water and cleaning fluid flowing into the upper water inlet pipe 505 are sprayed onto the top of the electroforming foil material 4 through the upper nozzle 504, and the water and cleaning fluid flowing into the lower water inlet pipe 509 are sprayed onto the bottom of the electroforming foil material 4 through the lower nozzle 508, so that cleaning fluid is sprayed both above and below the electroforming foil material 4, which can remove stubborn oil stains and ensure the cleaning effect of the cleaning mechanism 6 on the electroforming foil material 4.

[0025] Reference Figure 2 and Figure 4 The cleaning mechanism 6 includes a first fixed block 601 for support. A bidirectional screw 602 is movably connected to the top of the first fixed block 601. An adjusting wheel 603 is fixedly connected to the top of the bidirectional screw 602. The side of the bidirectional screw 602 has mirror-symmetrical threaded grooves. An upper moving plate 604 and a lower moving plate 606 are threadedly connected to the side of each threaded groove of the bidirectional screw 602. The upper moving plate 604 and the lower moving plate 606 move closer to or further away from each other. An upper cleaning block 60 is fixedly connected to the bottom of the upper moving plate 604. 5. A lower cleaning block 607 is fixedly connected to the top of the lower moving plate 606. Both the upper cleaning block 605 and the lower cleaning block 607 are made of rubber. The chemically formed foil raw material 4 is located between the upper cleaning block 605 and the lower moving plate 606. The upper moving plate 604 and the lower moving plate 606 are movably connected to the inside of the side away from the bidirectional screw 602. The upper moving plate 604 and the lower moving plate 606 are provided with limiting grooves that are adapted to the limiting rods 608. The bottom end of the limiting rods 608 is fixedly connected to a second fixing block 609.

[0026] In this embodiment, when the adjusting wheel 603 drives the bidirectional screw 602 to rotate, the upper moving plate 604 and the lower moving plate 606 on the side move away from each other or move closer to each other. When the upper moving plate 604 and the lower moving plate 606 move, they drive the upper cleaning block 605 and the lower cleaning block 607 to move away from each other or move closer to each other, thereby adjusting the pressure when the upper cleaning block 605 and the lower cleaning block 607 are in contact with each other, adjusting the pressure applied by the upper cleaning block 605 and the lower cleaning block 607 to the electroforming foil material 4, adapting to the electroforming foil material 4, and ensuring the cleaning effect of this application.

[0027] The working principle of this utility model is as follows: When treating the surface of the electroforming foil raw material 4, the adjusting wheel 603 is rotated according to the material and thickness of the electroforming foil raw material 4. When the adjusting wheel 603 rotates, it drives the bidirectional screw 602 to rotate. When the bidirectional screw 602 rotates, it causes the upper moving plate 604 and the lower moving plate 606 on the side to move away from or towards each other. When the upper moving plate 604 and the lower moving plate 606 move, they drive the upper cleaning block 605 and the lower cleaning block 607 to move away from or towards each other, thereby adjusting the pressure when the upper cleaning block 605 and the lower cleaning block 607 are in contact with each other, adjusting the pressure applied by the upper cleaning block 605 and the lower cleaning block 607 to the electroforming foil raw material 4, and adapting it to the electroforming foil raw material 4.

[0028] When the cleaning mechanism 6 is fully adapted to the electrolytic foil material 4, the feeding roller 1 delivers the electrolytic foil material 4, and the take-up roller 2 rewinds it. When the electrolytic foil material 4 passes through the spraying mechanism 5, water and cleaning fluid are introduced into the upper water inlet pipe 505. After flowing in the upper flow trough plate 503, the liquid enters the lower upper nozzle 504 and is finally sprayed onto the top of the electrolytic foil material 4 through the upper nozzle 504. Simultaneously, water and cleaning fluid are introduced into the lower water inlet pipe 509. After flowing in the lower flow trough plate 507, the liquid enters the upper lower nozzle 508 and is sprayed onto the bottom of the electrolytic foil material 4 through the lower nozzle 508. This ensures that cleaning fluid is sprayed both above and below the electrolytic foil material 4, which can remove stubborn oil stains and ensure the cleaning effect of the cleaning mechanism 6 on the electrolytic foil material 4.

[0029] In conclusion, the above are merely preferred embodiments of this utility model and are not intended to limit this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
