Description

Technical Field

[0001] This utility model relates to the field of corrosion foil production technology, specifically an acid scraping mechanism for corrosion foil production. Background Technology

[0002] Etched foil is a key material widely used in the manufacture of electronic components, especially in the production of aluminum electrolytic capacitors. With the rapid development of the electronics industry, the demand for etched foil is constantly increasing, and the quality requirements for its surface treatment are also rising. The production process of etched foil involves multiple steps, among which pickling is a crucial step used to remove the oxide layer and other impurities from the foil surface.

[0003] An investigation revealed that a Chinese utility model patent (publication number: CN211112313U) discloses a novel acid scraper for electrode foil. The scraper includes symmetrically arranged supports, with two sets of fixed shafts connected between the supports. These fixed shafts are arranged vertically, with a rotating tube fitted onto the lower set and a cotton sleeve fitted onto the upper set. The etched foil passes between the two rotating tubes and then through the two cotton sleeves. This invention significantly improves the removal of residual electrolyte on the foil surface, reduces ineffective corrosion after exiting the electrolytic cell, and lowers capacity decay. It also increases production capacity by approximately 3% and prevents foil deformation and wrinkling, resulting in a smoother aluminum foil.

[0004] Although the aforementioned patent uses a transfer tube for pre-acid scraping and then a cotton transfer tube for secondary removal of the plating solution, which can significantly reduce the residual plating solution on the foil surface, it still has some shortcomings. For example, although the cotton transfer tube can absorb the acid solution, some plating solution will still remain on the acid scraping mechanism. If it is not cleaned, it will corrode or contaminate the acid scraping mechanism, affecting the next use of the acid scraping component and reducing the service life of the acid scraping mechanism.

[0005] Therefore, this utility model provides an acid scraping mechanism for producing etched foil to solve the above problems. Utility Model Content

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] This utility model relates to an acid scraping mechanism for producing corrosion foil, combined with the attached... Figure 1 To be continued Figure 5 The specific embodiments of this utility model are described in detail below. The acid scraping mechanism includes a base 1, a first support plate 2, an adjustment component 3, an acid scraping component 4, and a cleaning component 5. Two first support plates 2 are welded to the top of the base 1, and an acid scraping component 4 is installed between the two first support plates 2 for scraping acid off the surface of the corrosion foil. An adjustment component 3 is provided inside the first support plate 2, which can be used to adjust the height or position of the acid scraping component 4 to accommodate corrosion foils of different thicknesses. A cleaning component 5 is provided on the outside of the acid scraping component 4 for periodically cleaning residual acid on the surface of the acid scraping component 4 to prevent acid from corroding or contaminating the equipment.

[0026] Combined with appendix Figure 1 and attached Figure 2 The acid scraping assembly 4 includes two connecting shafts 41, which are respectively installed between the adjusting block 33 and the guide block 35 and between the two first support plates 2. A first acid scraping roller 42 is fixedly connected to the outer wall of one connecting shaft 41, and a second acid scraping roller 43 is fixedly connected to the outer wall of the other connecting shaft 41. The second acid scraping roller 43 is located below the first acid scraping roller 42. The first acid scraping roller 42 is mainly used to initially scrape off most of the acid liquid on the surface of the corrosion foil, while the second acid scraping roller 43 further removes the residual acid liquid, thereby realizing a two-stage acid scraping design. This design significantly improves the acid scraping efficiency and reduces the amount of residual acid liquid. The two ends of the connecting shaft 41 are installed between the adjusting block 33 and the guide block 35 through bearings to ensure that the acid scraping assembly 4 maintains stable operation during operation. The surface material of the first acid scraping roller 42 and the second acid scraping roller 43 is selected from corrosion-resistant materials, such as polytetrafluoroethylene or stainless steel, to extend their service life. The distance between the two acid scraping rollers is designed according to the thickness of the corrosion foil and the viscosity of the acid liquid.

[0027] Combined with appendix Figure 3 and attached Figure 5The cleaning component 5 includes a servo motor 51, a lead screw 52, ​​a moving block 53, a limit rod 54, a water tank 55, a pump body 56, a water guide pipe 57, a U-shaped diversion frame 59, and spray holes 510. The servo motor 51 is fixedly connected inside the first support plate 2, and its output end is fixedly mounted with the lead screw 52 via a coupling. The outer wall of the lead screw 52 is threadedly connected to the moving block 53. The inside of the moving block 53 is slidably connected to the limit rod 54, which completely penetrates the moving block 53 and is fixedly installed between the two first support plates 2, ensuring that the moving block 53 moves in a straight line. The top of the moving block 53 is fixedly connected to the water tank 55, and the inner side of the top of the water tank 55 has a water filling hole 58 for adding cleaning water. The capacity of the water tank 55 is designed according to the cleaning frequency and water consumption to ensure... To ensure that cleaning water does not need to be added frequently during a single cleaning process, a pump body 56 is fixedly connected to the top of the water tank 55. Water guide pipes 57 are fixedly connected to both the front and rear sides of the pump body 56. The ends of the water guide pipes 57 extend into the diversion grooves opened inside the U-shaped diversion frame 59. The U-shaped diversion frame 59 is fixedly installed at the bottom of the moving block 53. Multiple spray holes 510 are opened inside it for spraying cleaning water onto the acid scraping assembly 4 to remove residual acid. The spray holes 510 are evenly distributed on the inner side of the U-shaped diversion frame 59, and the number is designed according to the actual cleaning needs to ensure that the cleaning water can cover the entire surface of the acid scraping assembly 4. The flow rate and pressure of the cleaning water are adjusted by the pump body 56 to ensure that residual acid is effectively removed without causing additional impact or damage to the acid scraping assembly 4.

[0028] The working process of cleaning component 5 is as follows: servo motor 51 is started, and servo motor 51 drives lead screw 52 to rotate; the rotation of lead screw 52 drives moving block 53 to move linearly along limit rod 54; when moving block 53 moves, the U-shaped diversion frame 59 fixed at its bottom moves accordingly; pump body 56 is started, and pump body 56 transports cleaning water in water tank 55 to diversion groove inside U-shaped diversion frame 59 through water guide pipe 57; cleaning water is sprayed out from spray hole 510 inside U-shaped diversion frame 59 and sprayed onto the surface of acid scraping component 4 to remove residual acid. The design of cleaning component 5 realizes automated cleaning function, significantly reduces manual maintenance costs, and extends the service life of acid scraping component 4.

[0029] Combined with appendix Figure 4The adjusting assembly 3 includes a threaded sleeve 31, a threaded rod 32, an adjusting block 33, a guide rod 34, and a guide block 35. The threaded sleeve 31 is fixed to the top of one of the first support plates 2, and the threaded rod 32 is threadedly connected to its inner side. The threaded rod 32 passes through a rectangular groove opened inside the first support plate 2, and the adjusting block 33 is installed at its bottom via a bearing. The other first support plate 2 has a guide groove inside, and the guide rod 34 is fixedly connected inside the guide groove. The guide block 35 is slidably connected to the outer wall of the guide rod 34. By rotating the threaded rod 32, the adjusting block 33 can move up and down, thereby adjusting the height or position of the acid scraping assembly 4 to adapt to corrosion foils of different thicknesses. The pitch and length of the threaded rod 32 are designed according to the adjustment range of the acid scraping assembly 4 to ensure that the adjusting block 33 can move up and down within a reasonable range. The cooperative design of the guide rod 34 and the guide block 35 ensures that the adjusting block 33 remains stable during movement and avoids the position of the acid scraping assembly 4 from shifting due to shaking. The operation of the adjusting assembly 3 is achieved by manually rotating the threaded rod 32, which is simple and reliable.

[0030] Combined with appendix Figure 1 The base 1 has a collection tank 6 inside, which is used to collect the acid produced during the acid scraping process. The collection tank 6 is rectangular in shape, and its depth and width are designed according to actual use needs to ensure that it can accommodate the amount of acid produced during the acid scraping process. A drain pipe 7 is fixedly connected to the front side of the base 1. The drain pipe 7 has a valve inside, which is used to discharge the acid in the collection tank 6. The valve is designed to control the discharge time of the acid and avoid acid leakage causing environmental pollution.

[0031] The specific application scenario of this utility model is as follows: In the production process of etched foil, after the pickling process, the etched foil enters the acid scraping mechanism. First, according to the thickness of the etched foil, the threaded rod 32 is rotated to adjust the height of the acid scraping component 4, so that the first acid scraping roller 42 and the second acid scraping roller 43 contact the surface of the etched foil. The etched foil passes between the first acid scraping roller 42 and the second acid scraping roller 43. The first acid scraping roller 42 initially scrapes off most of the acid liquid on the surface of the etched foil, and the second acid scraping roller 43 further removes the residual acid liquid. The scraped acid liquid flows into the collection tank 6 inside the base 1 and is discharged through the drain pipe 7. When a certain amount of residual acid liquid accumulates on the surface of the acid scraping component 4, the cleaning component 5 is started. The cleaning component 5 drives the lead screw 52 to rotate through the servo motor 51, which drives the moving block 53 to move linearly along the limit rod 54. At the same time, the pump body 56 is started to transport the cleaning water to the U-shaped diversion frame 59 through the water guide pipe 57. The cleaning water is sprayed out from the spray hole 510 to clean the residual acid liquid on the surface of the acid scraping component 4. The entire cleaning process is completed automatically without manual intervention.

[0032] This invention significantly improves acid scraping efficiency and product quality through a two-stage acid scraping design, automated cleaning function of the cleaning component, height adjustment function of the adjustment component, and the design of the collection tank and drain pipe. At the same time, it reduces maintenance costs and environmental pollution risks. The acid scraping mechanism has a reasonable structure, is easy to operate, and has reliable performance. It is suitable for various corrosion foil production lines and has broad application prospects.

[0033] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
