Description

Technical Field

[0001] This utility model relates to the field of electrode foil formation equipment technology, and in particular to a formation tank with an aluminum foil ductility enhancement device. Background Technology

[0002] The preparation process of electrode foil mainly includes melting, casting, cold rolling, formation, and cutting. Among them, the formation process is to endow the aluminum foil obtained from the cold rolling process with specific dielectric properties, so that it can be used as an electrode material for capacitors. The formation process is usually carried out in a formation tank containing a specific electrolyte. By using the aluminum foil as the anode and applying direct current, a dense hydrated oxide film is generated in situ on the surface of the aluminum foil through an electrochemical anodic oxidation reaction. The thickness of this oxide film is directly related to the formation voltage and determines the withstand voltage of the electrode foil.

[0003] In actual industrial production, in order to achieve the target withstand voltage, aluminum foil needs to be continuously passed through multiple forming tanks with progressively increasing voltages under the traction of a winding machine to carry out continuous step-by-step voltage boosting. However, aluminum foil undergoes severe plastic deformation during the cold rolling process, resulting in the accumulation of high internal stress. This internal stress caused by work hardening reduces the ductility of the aluminum foil, making it extremely prone to breakage during the winding process, thus reducing the production efficiency and product yield of the electrode foil. Utility Model Content

[0004] In view of this, it is necessary to provide a forming tank with an aluminum foil ductility enhancement device, which can release the internal stress accumulated inside the aluminum foil to improve the ductility of the aluminum foil, thereby reducing the probability of the aluminum foil breaking during the traction process of the winding machine, and thus improving the production efficiency and product yield of the electrode foil.

The top of the first transverse slider is provided with an adjustment groove. The bottom surface of the adjustment plate is slidably mounted on the top surface of the first fixed plate. The horizontal adjustment rod is rotatably mounted on the adjustment plate in the vertical direction, with its bottom end extending into the adjustment groove and fixed with an adjustment gear. The outer side of the first fixed plate is provided with an adjustment gear track in the horizontal direction that meshes with the adjustment gear. Rotating the horizontal adjustment rod drives the adjustment gear to roll along the adjustment gear track, thereby causing the first transverse slider to move horizontally... Directional movement; a sleeve is provided on the outer side of the first horizontal slider, and a guide hole is opened on the first vertical slider. The vertical adjusting rod is rotatably mounted on the adjusting plate in the vertical direction. Its bottom end passes through the guide hole and rotatably extends into the sleeve.

These components are rotatably mounted in the forming tank in descending order of height, with the height of the second guide component lower than the electrolyte level in the forming tank. Thus, the first guide component first alters the aluminum foil's path, immersing it in the electrolyte of the forming tank. Then, the second and third guide components guide the aluminum foil along an "S"-shaped path, causing it to repeatedly bend within the electrolyte, thereby promoting lattice slippage and displacement within the aluminum foil. The repositioning process releases the internal stress accumulated in the aluminum foil during the cold rolling process, improving its ductility and reducing the probability of breakage during winding. This enhances the production efficiency and yield of the electrode foil. Simultaneously, since the entire process takes place in the electrolyte of the forming tank, the electrolyte buffers the localized tensile and shear stresses generated during repeated bending, reducing potential damage from stress concentration. Furthermore, the lubricating effect of the electrolyte reduces friction between the aluminum foil and the second and third guiding components immersed in the liquid, mitigating mechanical damage to the hydrated oxide film on the aluminum foil surface. The electrolyte also promptly wets and repairs the bent area, maintaining the integrity of the hydrated oxide film and preventing damage from bending operations. Attached Figure Description

Detailed Implementation

[0024] The technical solutions and effects of the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings.

[0025] Please refer to Figures 1 to 3This utility model provides a forming tank 10 with an aluminum foil ductility enhancement device, including a forming tank 20 and a ductility enhancement component 30. The ductility enhancement component 30 is disposed at the input end of the forming tank 20 and includes a first guide component 31, a second guide component 32, and a third guide component 33. The first guide component 31, the second guide component 32, and the third guide component 33 are rotatably installed in the forming tank 20 in descending order of height, and the height of the second guide component 32 is lower than the liquid level of the electrolyte in the forming tank 20. The first guide component 31 is used to guide the travel path of the aluminum foil, so that it is immersed in the electrolyte in the forming tank 20. The second guide component 32 and the third guide component 33 are used to make the aluminum foil move in an "S" shaped path in the electrolyte, so that the aluminum foil is continuously bent and deformed in the electrolyte. Thus, the travel path of the aluminum foil is first changed by the first guide component 31, so that the aluminum foil is immersed in the electrolyte in the forming tank 20; then... The aluminum foil is guided along an "S"-shaped path by the second guide component 32 and the third guide component 33, causing it to bend repeatedly in the electrolyte of the forming tank 20. This promotes slippage and displacement reorganization of the internal lattice of the aluminum foil, thereby releasing the internal stress accumulated during the cold rolling process, improving the ductility of the aluminum foil, and reducing the probability of breakage during the winding process of the coiler. This improves the production efficiency and product yield of the electrode foil. At the same time, since the entire process takes place in the electrolyte of the forming tank 20, the electrolyte can buffer the local tensile force and shear stress generated by the repeated bending of the aluminum foil, reducing the potential damage to the aluminum foil caused by stress concentration. In addition, the lubrication effect of the electrolyte also reduces the friction between the aluminum foil and the second guide component 32 and the third guide component 33 immersed in the liquid, reducing mechanical damage to the hydrated oxide film on the surface of the aluminum foil. The electrolyte can also promptly wet and repair the bending area, maintaining the integrity of the hydrated oxide film and preventing it from being damaged by the bending operation.

[0026] In this embodiment, the travel path of the aluminum foil at the input end of the forming tank 20 is as follows: Figure 2 As shown.

[0027] Please refer to Figure 3Furthermore, the forming tank 10 with the aluminum foil ductility enhancement device also includes an adjustment component 40, which includes an active adjustment component 41 and a passive adjustment component 42.

Specifically, the passive adjustment component 42 moves synchronously with the active adjustment component 41, which enables the second guide component 32 to maintain a stable horizontal posture during the adjustment process and avoids positional deviation caused by unilateral support. By adjusting the position of the second guide component 32, the bending path and degree of bending of the aluminum foil in the electrolyte can be adjusted according to the width and thickness of the aluminum foil. For example, when the aluminum foil is thick, increasing the degree of bending can effectively promote the release of internal stress; when the aluminum foil is thin, decreasing the degree of bending can effectively reduce damage to the surface of the aluminum foil.

[0028] Please refer to Figure 4 Furthermore, the active adjustment component 41 includes a first fixed plate 411, a first transverse slider 412, and a first longitudinal slider 413.

Specifically, when the first transverse slider 412 moves in the horizontal direction, it drives the second guide component 32 to move in the horizontal direction to change the transverse bending position of the aluminum foil; when the first longitudinal slider 413 moves in the vertical direction, it drives the second guide component 32 to move in the vertical direction to change the longitudinal bending position of the aluminum foil, thereby realizing the control of the bending path of the aluminum foil.

The horizontal adjustment rod 415 is rotatably mounted on the adjustment plate 414 in the vertical direction, with its bottom end extending into the adjustment groove 4123 and fixed with an adjustment gear 417. The outer side of the first fixed plate 411 is provided with a locking mechanism along the horizontal direction... The adjusting gear 417 meshes with the adjusting gear rail, so that rotating the horizontal adjusting rod 415 drives the adjusting gear 417 to roll along the adjusting gear rail, thereby driving the first transverse slider 412 to move horizontally. A sleeve 4124 is provided on the outer side of the first transverse slider 412. A guide hole 4132 is opened on the first longitudinal slider 413. The vertical adjusting rod 416 is rotatably mounted on the adjusting plate 414 in the vertical direction. Its bottom end passes through the guide hole 4132 and extends rotatably into the sleeve 4124. The middle part of the vertical adjusting rod 416 is aligned with the guide hole.

[0031] In this embodiment, the top surface of the first fixing plate 411 has two parallel T-shaped guide rails, and the bottom surface of the adjusting plate 414 has a corresponding T-shaped groove, so that the sliding connection between the adjusting plate 414 and the first fixing plate 411 can be realized through the cooperation between the T-shaped guide rails and the T-shaped groove; the sleeve 4124 is provided with a bearing to realize the rotational connection between the sleeve 4124 and the bottom of the vertical adjusting rod 416; the middle part of the vertical adjusting rod 416 has a threaded section, and the guide hole 4132 has a thread to realize the threaded cooperation between the vertical adjusting rod 416 and the guide hole 4132.

[0032] Please refer to Figure 4 Furthermore, each locking assembly 418 includes a locking gear 4181, a locking seat 4182, and a locking pin 4183.

By setting the locking group 418, the second guide assembly 32 can be prevented from being accidentally displaced during operation due to vibration or other reasons, thereby ensuring the consistency of the aluminum foil bending path.

[0033] Please refer to Figure 9Furthermore, the passive adjustment component 42 includes a second fixed plate 421, a second transverse slider 422, and a second longitudinal slider 423. The sidewall of the forming groove 20 opposite to the first fixed plate 411 is fixedly connected to the inner side of the second fixed plate 421. The inner side of the second transverse slider 422 is slidably mounted on the outer side of the second fixed plate 421 for sliding horizontally on the outer side of the second fixed plate 421. The inner side of the second longitudinal slider 423 is slidably mounted on the outer side of the second transverse slider 422 for sliding vertically on the outer side of the second transverse slider 422.

Specifically, the guide roller 312 is made of an inert material with corrosion resistance and a smooth surface, such as alumina ceramic or polytetrafluoroethylene, to effectively resist the long-term erosion of the electrolyte, maintain its own smoothness, provide smooth support for the aluminum foil, reduce the risk of scratching and peeling of the hydrated oxide film, and thus ensure the integrity of the hydrated oxide film.

[0036] Example 1: Adjustment process of the second guiding component 32

[0037] 1. To unlock, pull out the locking pins 4183 of the two locking groups 418 so that their toothed ends disengage from the corresponding locking gears 4181;

[0038] 2. Horizontal position adjustment: Rotate the horizontal adjustment rod 415 to drive the adjustment gear 417 at its bottom to rotate. Since the adjustment gear 417 meshes with the adjustment gear rail fixed on the first fixed plate 411, it drives the first transverse slider 412 to slide horizontally along the convex guide rail 4111 of the first fixed plate 411, driving the first longitudinal slider 413 and the first end of the second guide component 32 fixed on the first longitudinal slider 413 to move horizontally together; at the same time, the second end of the second guide component 32 drives the second transverse slider 422 to slide horizontally synchronously along the second fixed plate 421.

[0039] 3. Vertical position adjustment: Rotate the vertical adjustment rod 416. Since its bottom end is rotatably connected to the sleeve 4124 of the first transverse slider 412 through a bearing and cannot move axially, and its middle threaded section is threadedly engaged with the guide hole 4132 of the first longitudinal slider 413, this rotational motion is converted into linear motion of the first longitudinal slider 413 in the vertical direction through the threaded pair. The first longitudinal slider 413 is guided by the protrusions 4131 at both ends and the guide grooves 4122 on the side of the first transverse slider 412, thereby smoothly driving the first end of the second guide assembly 32 to rise and fall. At the same time, the second end of the second guide assembly 32 pushes the second longitudinal slider 423 of the passive adjustment assembly 42, causing it to slide synchronously in the vertical direction on the second transverse slider 422, ensuring that the second guide assembly 32 always remains horizontal during the vertical adjustment process.

[0040] 4. Relock: After completing the horizontal and vertical position adjustment, push the locking pins 4183 of the two locking groups 418 inward so that their toothed ends re-engage with the corresponding locking gears 4181, thereby locking the horizontal adjusting rod 415 and the vertical adjusting rod 416 and fixing the second guide assembly 32 in the adjusted position.

The middle part of the vertical adjusting rod is threaded into the guide hole so that the first vertical slider can be driven to move in the vertical direction by rotating the vertical adjusting rod. The fixed ends of the two locking groups are mounted on the top surface of the adjusting plate, and their movable ends are respectively facing the horizontal adjusting rod and the vertical adjusting rod so that the horizontal adjusting rod and the vertical adjusting rod can be locked or released by the extension and retraction of the movable ends of the two locking groups.

6. The forming tank with an aluminum foil ductility enhancement device as described in claim 5, characterized in that, Each locking assembly includes a locking gear, a locking seat, and a locking pin. The locking gear is fixedly mounted on the horizontal or vertical adjusting rod and is located above the top surface of the adjusting plate. The locking seat is fixedly installed on the top surface of the adjusting plate, and has a locking groove at one end facing the horizontal or vertical adjusting rod. The first end of the locking pin is slidably installed in the locking groove, and the second end has a toothed structure that meshes with the locking gear. By sliding the locking pin, the second end can be engaged or disengaged from the locking gear, thereby locking or releasing the horizontal or vertical adjusting rod.

7. The forming tank with an aluminum foil ductility enhancement device as described in claim 6, characterized in that, The passive adjustment assembly includes a second fixed plate, a second transverse slider, and a second longitudinal slider. The sidewall of the formation groove opposite to the first fixed plate is fixedly connected to the inner side of the second fixed plate. The inner side of the second transverse slider is slidably mounted on the outer side of the second fixed plate for sliding horizontally on the outer side of the second fixed plate. The inner side of the second longitudinal slider is slidably mounted on the outer side of the second transverse slider for sliding vertically on the outer side of the second transverse slider. The second end of the second guide assembly is fixedly mounted on the outer side of the second longitudinal slider so that the second transverse slider and the second longitudinal slider move horizontally and vertically as the second guide assembly moves, thereby stably supporting the second guide assembly and keeping the second guide assembly in a horizontal state.

8. The forming tank with an aluminum foil ductility enhancement device as described in claim 7, characterized in that, The first, second, and third guiding components each include a roller and a guide roller. The first end of the roller is fixedly mounted on a first fixed plate or a first longitudinal slider, and the second end is fixedly mounted on a second fixed plate or a second longitudinal slider. The guide roller is rotatably mounted on the roller and is used to guide the aluminum foil's travel path, so that the aluminum foil moves along a preset "S" shaped path in the electrolyte of the forming tank, thereby causing the aluminum foil to continuously bend and deform in the electrolyte.
