Description

Technical Field

[0001] This utility model relates to the field of electrode foil production technology, and more specifically to a surface treatment device for the production of electrode foil for new energy vehicles. Background Technology

[0002] In the development of new energy vehicles, electrode foil, as a key component of the battery, plays a crucial role in the overall performance of the battery. Surface treatment of electrode foil is a key step in improving its performance, including surface coating, etching, and other surface modification processes. These treatment methods can improve the conductivity, stability, and corrosion resistance of the electrode foil, thereby increasing the battery's energy density, charge-discharge efficiency, and cycle life.

[0003] However, existing electrode foil surface treatment technologies face numerous challenges in ensuring uniform processing. Traditional methods often fail to guarantee uniform treatment across all parts of the electrode foil, leading to variations in product quality. This results in inconsistent coating thickness and uneven etching on the electrode foil surface, affecting the uniformity of current distribution during battery charging and discharging. During battery use, this non-uniformity can lead to localized overheating or undercooling, thereby impacting battery performance and reliability, and shortening battery life.

[0004] In the production of electrode foil for new energy vehicles, the unloading operation of traditional surface treatment devices after electrode foil processing is often complex and inconvenient. Some early devices adopted a fixed structure design, where the angle of the cleaning roller or processing chamber could not be changed, making it difficult for the electrode foil to be discharged automatically after processing. This usually required manual disassembly or the use of additional auxiliary tools to remove the electrode foil from the device, which was not only time-consuming and labor-intensive but also prone to damaging the electrode foil, affecting product quality.

[0005] Therefore, it is necessary to propose a surface treatment device for the production of electrode foil for new energy vehicles to solve the above problems. Utility Model Content

[0011] Furthermore, a fixed box is fixedly connected to one end of the upper surface of the base plate, and a conveying frame is slidably connected to one side of the fixed box.

[0012] Furthermore, a second motor is fixedly installed inside the fixed box, and a screw is fixedly connected to one end of the output shaft of the second motor. The screw is adapted to the conveyor frame.

[0017] Furthermore, a third telescopic rod is fixedly installed on one side of the upper surface of the base plate, and the other end of the third telescopic rod is fixedly connected to the sliding plate.

[0018] Furthermore, a cleaning rack is fixedly connected to the upper surface of the base plate. The cleaning rack is arc-shaped and can spray water onto the inner hardware parts from multiple angles simultaneously for cleaning.

[0019] (III) Beneficial Effects

[0020] The beneficial effects of this utility model are as follows:

[0021] 1. This utility model, through the design of toothed grooves, a first motor and a drive gear matching to drive the rotating ring inside the processing ring to rotate, ensures that all parts of the electrode foil receive uniform surface treatment, avoiding product quality differences caused by uneven local treatment. Whether it is surface coating, etching treatment or other surface modification processes of the electrode foil, uniform treatment helps to improve the overall performance consistency of the electrode foil, thereby improving the performance and reliability of new energy vehicle batteries. For example, in the coating treatment of electrode foil, uniform coating thickness can ensure the uniformity of current distribution during battery charging and discharging, reduce local overheating or overcooling, and extend battery life.

[0022] 2. In this utility model, the second telescopic rod enables the baffle to be raised and lowered. This design provides high flexibility for the processing of electrode foil. Operators can precisely adjust the position of the baffle according to electrode foils of different specifications, sizes, and processing requirements, thereby controlling the effective processing area of ​​the electrode foil inside the processing ring. For smaller electrode foils, the baffle can be lowered appropriately to concentrate the processing of specific areas; while for larger electrode foils or those requiring comprehensive processing, the baffle can be raised to expand the processing range. This flexible control capability allows the device to adapt to diverse production needs, improving production efficiency and product versatility. The baffle not only shields the electrode foil inside the processing ring but also provides protection during the processing. In some surface treatment processes, such as plasma treatment and chemical etching, some spatter may be generated. The baffle can effectively prevent these substances from contaminating and damaging the untreated parts of the electrode foil.

[0023] 3. In this utility model, after the baffle is lifted by the second telescopic rod, the angle of the second ring support can be changed by the synergistic action of the first telescopic rod, the movable connecting block and the connecting frame. This design allows the device to easily discharge the processed electrode foil after processing. In actual operation, the operator can quickly adjust the angle of the first ring support without complicated operating procedures to achieve automated material discharge. For example, after a batch of electrode foil has been processed, the first ring support can be tilted or rotated to a suitable angle by simply operating the second telescopic rod, and the electrode foil can be smoothly discharged by gravity or a simple mechanical structure, which greatly improves production efficiency and reduces manual intervention and production interruptions caused by poor material discharge.

[0030] 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.

[0031] Example 1

[0032] Please see Figure 1 , 25. A surface treatment device for producing electrode foil for new energy vehicles includes a base plate 1 with a first telescopic rod 2 fixedly installed on one side of the upper end. The end of the first telescopic rod 2 is rotatably connected to a connecting frame 11, and the other end of the connecting frame 11 is rotatably connected to a movable connecting block 10. The top of the movable connecting block 10 is fixedly connected to a second ring bracket 13. A fixed connecting piece 3 is fixedly connected to the upper surface of the base plate 1. The upper end of the fixed connecting piece 3 is rotatably connected to a first ring bracket 4. A processing ring 5 is fixedly connected to the inner side of the first ring bracket 4 and the second ring bracket 13. A rotating ring 29 is rotatably connected to the inner side of the processing ring 5. A processing mechanism is fixedly connected to the inner side of the rotating ring 29. The outer end of the rotating ring 29 has multiple toothed grooves 6 arranged in a ring array. A first motor 7 is fixedly installed on the upper end of the processing ring 5. One end of the output shaft of the first motor 7 is fixedly connected to a drive gear 8, which meshes with the toothed grooves 6. A second telescopic rod 12 is symmetrically fixedly installed inside both ends of the first ring bracket 4. A baffle 14 is fixedly connected to the top of the second telescopic rod 12.

[0033] In this embodiment, the design of the rotating ring 29 inside the processing ring 5 is driven by the toothed groove 6, the first motor 7 and the active gear 8. This stable rotation method ensures that all parts of the electrode foil can be uniformly surface treated, avoiding product quality differences caused by uneven local treatment. Whether it is the surface coating, etching treatment or other surface modification processes of the electrode foil, uniform treatment helps to improve the overall performance consistency of the electrode foil, thereby improving the performance and reliability of new energy vehicle batteries. For example, in the coating treatment of the electrode foil, a uniform coating thickness can ensure the uniformity of current distribution during battery charging and discharging, reduce local overheating or overcooling, and extend the battery's service life.

[0034] The second telescopic rod 12 enables the baffle 14 to be raised and lowered. This design provides high flexibility for the processing of electrode foil. Operators can precisely adjust the position of the baffle 14 according to electrode foils of different specifications, sizes, and processing requirements, thereby controlling the effective processing area of ​​the electrode foil inside the processing ring 5. For smaller electrode foils, the baffle 14 can be lowered appropriately to concentrate the processing of specific areas; while for larger electrode foils or those requiring comprehensive processing, the baffle 14 can be raised to expand the processing range. This flexible adjustment capability allows the device to adapt to diverse production needs, improving production efficiency and product versatility. The baffle 14 not only shields the electrode foil inside the processing ring 5 but also plays a protective role during the processing. In some surface treatment processes, such as plasma treatment and chemical etching, some spatter may be generated. The baffle 14 can effectively prevent these substances from contaminating and damaging the untreated parts of the electrode foil, ensuring the processing accuracy and quality of the electrode foil. At the same time, the shielding function can also prevent external impurities from entering the processing area, avoiding interference with the processing process and further improving the quality stability of the product.

[0035] After the baffle 14 is lifted by the second telescopic rod 12, the angle of the second ring support 13 can be changed by the coordinated action of the first telescopic rod 2, the movable connecting block 10 and the connecting frame 11. This design allows the device to easily discharge the processed electrode foil after processing. In actual operation, the operator can quickly adjust the angle of the first ring support 4 without complicated operating procedures to achieve automated material discharge. For example, after a batch of electrode foil is processed, the first ring support 4 can be tilted or rotated to a suitable angle by simply operating the first telescopic rod 2, and the electrode foil can be discharged smoothly by gravity or a simple mechanical structure, which greatly improves production efficiency and reduces manual intervention and production interruptions caused by poor material discharge.

[0036] Example 2

[0037] Please see Figure 3 This embodiment is a further optimization based on embodiment 1. Specifically, a fixed box 15 is fixedly connected to the upper surface of one end of the base plate 1, and a conveying frame 16 is slidably connected to one side of the fixed box 15.

[0038] Specifically, a second motor 17 is fixedly installed inside the fixed box 15, and a screw 18 is fixedly connected to one end of the output shaft of the second motor 17. The screw 18 is adapted to the conveyor frame 16.

[0039] Specifically, a first roller 19 is rotatably connected to one end of the conveying frame 16, a fixed plate 20 is fixedly connected to the bottom end of the conveying frame 16, and a second roller 21 is rotatably connected to one side of the lower end of the fixed plate 20.

[0040] Specifically, an auxiliary roller 22 is movably connected to one end of the inner side of the fixed box 15, and an active roller 23 is fixedly installed at the bottom inner side of the fixed box 15. The active roller 23 has a built-in motor.

[0041] Specifically, a conveyor belt 24 is connected between the first roller 19, the second roller 21, the auxiliary roller 22 and the driving roller 23, and the upper surface of the conveyor belt 24 is provided with anti-slip grooves.

[0042] In this embodiment, the combination of the second motor 17 and the screw 18 enables the conveying movable frame 16 to achieve telescopic sliding. This ingenious design automates the feeding process. During the operation of the production line, there is no need for manual placement of electrode foil, saving labor and time costs. Compared with the traditional method of manual feeding, it not only improves production efficiency but also reduces the occurrence of misoperation and production interruption caused by human factors. For example, in large-scale production, automated feeding can continuously and stably provide electrode foil for subsequent surface treatment processes, ensuring the continuity and efficiency of the entire production process.

[0043] The cooperation between the fixed plate 20 and the second roller 21 enables the conveyor belt 24 to be displaced. This function enhances the adaptability of the device to electrode foils of different specifications. In actual production, the electrode foils may have size differences due to design or process requirements. The device can easily handle electrode foils of different widths and lengths by adjusting the position of the conveyor belt 24, ensuring that they can be accurately transported into the processing ring 5 for surface treatment. This flexibility enables the device to meet diverse production needs and improves its versatility and market competitiveness.

[0044] The first roller 19, the second roller 21, the auxiliary roller 22, and the driving roller 23 work together to achieve smooth movement of the conveyor belt 24. During the conveying of the electrode foil, these rollers ensure that the conveyor belt 24 maintains constant tension, preventing the electrode foil from shaking, wrinkling, or shifting during the conveying process. The stable conveying process helps ensure that the electrode foil is in an ideal state when it enters the processing ring 5, so that subsequent surface treatment can be applied to the surface of the electrode foil evenly and accurately, thereby improving the surface treatment quality of the electrode foil. For example, during the coating process, stable electrode foil conveying can ensure that the coating thickness is uniform and consistent, improving the conductivity and corrosion resistance of the electrode foil.

[0045] Example 3

Specifically, a slide rail 25 is symmetrically fixedly connected to one end of the upper surface of the base plate 1, and a sliding plate 26 is slidably connected to the upper end of the slide rail 25. A drainage groove is provided on the inner side of the sliding plate 26.

[0047] Specifically, a third telescopic rod 27 is fixedly installed on one side of the upper surface of the base plate 1, and the other end of the third telescopic rod 27 is fixedly connected to the sliding plate 26.

[0048] Specifically, a cleaning rack 28 is fixedly connected to the upper surface of the base plate 1, and the cleaning rack 28 is arc-shaped.

[0049] In this embodiment, the slide 25, the slide plate 26, the third telescopic rod 27 are adapted to the cleaning rack 28, and after the external treatment liquid is applied, multiple processing functions for the electrode foil can be realized. This multi-functional integrated design concept integrates the conveying, cleaning and other possible surface treatment processes of the electrode foil into one device. In the actual production process, the electrode foil can continuously complete multiple processing steps within the device without the need to transfer between different devices, thereby reducing the time wasted in intermediate links and the risk of electrode foil damage caused by the transfer process. For example, after the electrode foil enters the device, the electrode foil can move smoothly on the slide 25 through the cooperation of the slide plate 26 and the third telescopic rod 27. At the same time, the external treatment liquid can clean, etch or perform other surface modification treatments on the electrode foil, making the entire production process more compact and efficient.

[0050] In summary, this utility model, by realizing functions such as automated feeding, conveyor belt displacement, and stable conveying, brings an efficient, flexible, and high-quality production experience to the electrode foil production process. It is of great significance to improving the production efficiency and product quality of electrode foil for new energy vehicles.
