Description

Technical Field

[0001] This utility model relates to the field of electrode foil pickling technology, and more specifically to a miniaturized electrode foil processing pickling device for large-capacity capacitors. Background Technology

[0002] In the production of miniaturized, high-capacity capacitors, the processing quality of the electrode foil has a crucial impact on its performance. Among these processes, pickling is one of the key steps in electrode foil processing, as it effectively removes oxide layers and impurities from the electrode foil surface, thereby improving the conductivity and reliability of the electrode foil.

[0003] Traditional electrode foil pickling equipment often has several shortcomings. Firstly, the movement and positioning of the electrode foil during pickling typically rely on manual operation, which is not only inefficient but also makes it difficult to guarantee the accuracy and stability of the electrode foil's position during pickling, easily leading to uneven pickling and affecting the pickling effect. Secondly, existing pickling equipment lacks effective protective measures when spraying the electrode foil. Contaminants adhering to the electrode foil surface can easily reduce the pickling effect, and the pickling liquid may accidentally injure nearby personnel, posing a safety hazard to operators. Furthermore, after pickling, pickling liquid often remains on the electrode foil surface. If not cleaned promptly, this residue not only adversely affects the quality of the electrode foil, such as causing rust and affecting its electrical properties, but also poses a risk of injury to workers and environmental pollution during subsequent processing.

[0004] Therefore, it is necessary to propose a miniaturized pickling device for electrode foil processing of large-capacity capacitors to solve the above problems. Utility Model Content

This invention provides a miniaturized pickling device for electrode foil processing of large-capacity capacitors.

[0025] 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.

[0026] Example 1

[0027] Please see Figure 1-3A pickling apparatus for processing electrode foil of a miniaturized high-capacity capacitor includes a pickling tank 1. Limiting grooves 4 are formed on both inner walls of the pickling tank 1. A movable plate 5 is slidably connected between the two limiting grooves 4. A support frame 6 is fixedly connected to the top of the movable plate 5. A fixed frame 7 is fixedly connected to the side of the pickling tank 1. A fixed plate 8 is fixedly connected to the side of the pickling tank 1 away from the fixed frame 7. A lead screw 9 is rotatably connected between the fixed frame 7 and the fixed plate 8. A movable block 11 is threaded onto the outer side of the lead screw 9. Two rotating rods 13 and a fan 14 are rotatably connected between the two inner walls of the pickling tank 1. A second motor 17 is fixedly connected to the side of the pickling tank 1, and the output shaft of the second motor 17 passes through the pickling tank 1. One of the rotating rods 13 is fixedly connected. A partition 2 is fixedly connected between the inner walls of both sides of the pickling tank 1. A filter plate 3 is fixedly connected between the partition 2 and one of the inner walls of the pickling tank 1. A first motor 10 is fixedly connected to the side of the fixed frame 7. The output shaft of the first motor 10 passes through the fixed frame 7 and is fixedly connected to the lead screw 9. Telescopic rods 12 are fixedly connected to both ends of the bottom of the moving block 11. A moving plate 5 is fixedly connected to the end of the telescopic rod 12 away from the moving block 11. Multiple fixed blocks 19 are fixedly connected to the outside of the rotating rod 13. A nozzle 20 is fixedly connected to the side of the fixed block 19. A hose 21 is connected to the side of the nozzle 20. The end of the hose 21 away from the nozzle 20 is connected to the water outlet pipe 18.

[0028] In this embodiment, the first motor 10 drives the lead screw 9 to rotate, causing the moving block 11 to move along the lead screw 9. Then, the telescopic rod 12 drives the moving plate 5 to move smoothly, thereby achieving precise position control of the electrode foil. This automated movement method, compared with manual operation, can transport the electrode foil to the designated position more quickly and accurately, reducing the time spent on the electrode foil during handling and positioning, and significantly improving production efficiency. Especially in large-scale production, it can effectively shorten the overall production cycle. From the movement of the electrode foil and its docking with the bottom of the water outlet pipe 18, to the subsequent rinsing by the nozzle 20, drying by the fan 14, and contact with the pickling liquid, a series of operations can be completed automatically in the device. The entire process does not require much manual intervention, forming a coherent and efficient production process. This avoids the time wasted due to manual handover or operation changes, and greatly improves production efficiency.

[0029] The second motor 17 drives the rotating rod 13 to rotate, which in turn drives the fixed block 19 and the nozzle 20 to rotate synchronously. This allows the nozzle 20 to thoroughly and evenly rinse the electrode foil. This dynamic rinsing method ensures that all parts of the electrode foil surface can fully contact the water flow, effectively removing the dirt attached to the electrode foil surface and avoiding the problem of the pickling effect being affected by the dirt residue. This improves the quality of pickling. The blower 14 dries the electrode foil in time after rinsing to prevent moisture residue. Residual moisture may cause a series of problems in subsequent processing or use. Timely drying ensures the quality stability of the electrode foil, extends its service life, and also provides good conditions for subsequent processing and use.

[0030] During the pickling process, the device is in a relatively enclosed state, and its rational structural design prevents the pickling liquid from splashing or leaking. For example, when rinsing and drying the electrode foil, the operations are carried out in an orderly manner inside the device, avoiding the possibility of accidental injury to surrounding personnel by the pickling liquid and effectively ensuring the personal safety of operators. The design of this device allows the entire pickling process to be carried out in a closed space, reducing the environmental pollution caused by the evaporation of pickling liquid and the discharge of waste liquid. At the same time, the effective cleaning and recycling of residual pickling liquid on the surface of the electrode foil reduces the amount of pollutants emitted.

[0031] Example 2

[0032] Please see Figure 1 , 2 In embodiment 4, this embodiment is a further optimization based on embodiment 1. Specifically, the pickling tank 1 has three synchronous pulleys 15 on its side. The three synchronous pulleys 15 are respectively fixedly connected to two rotating rods 13 and a fan 14. The three synchronous pulleys 15 are connected by a transmission belt 16. The pickling tank 1 has two water outlet pipes 18 fixedly connected inside. The pickling tank 1 has a water pump 22 fixedly connected to its side. The water pump 22's water inlet penetrates the pickling tank 1 and is located inside the pickling tank 1. The water pump 22's water outlet is connected to one of the water outlet pipes 18.

[0033] In this embodiment, by setting two water outlet pipes 18 and cooperating with the nozzles 20, multi-angle and all-round rinsing of the electrode foil surface is achieved. Compared with the rinsing method of a single water outlet pipe and nozzle, this design can more thoroughly remove the residual acid pickling liquid and impurities on the electrode foil surface, improving the cleaning effect and quality. The simultaneous operation of multiple nozzles 20 makes the water flow distribution on the electrode foil surface more uniform, avoiding the problem of incomplete cleaning in some areas due to uneven water flow.

[0034] The improved cleaning mechanism further reduces the amount of acid pickling liquid remaining on the electrode foil surface. This not only reduces the risk of workers coming into contact with acid during subsequent operations, but also reduces potential safety hazards caused by acid residue, providing stronger protection for the company's production safety. It effectively cleans the acid pickling liquid from the electrode foil surface, reduces the evaporation and diffusion of acid pickling liquid in the air, thereby improving the odor and air quality of the working environment.

[0035] Working principle: During use, one of the water outlet pipes 18 is connected to an external water source. The electrode foil is then moved into the support frame 6. The first motor 10 is then started, causing the lead screw 9 to rotate. The rotation of the lead screw 9 moves the moving block 11, which in turn moves the moving plate 5 via the telescopic rod 12. The moving plate 5 then moves the electrode foil, which eventually reaches the bottom of the water outlet pipe 18 connected to the water pump 22. At this point, the second motor 17 rotates the rotating rod 13, which in turn causes the fixed block 19 to rotate the nozzle 20. Simultaneously, the water pump 22 draws water from the pickling tank 1, causing the nozzle to rotate. The head 20 rinses the electrode foil, and the residue after rinsing the electrode foil remains on the top of the filter plate 3. Then the electrode foil moves to the bottom of the blower 14. At this time, the blower 14 starts to rotate through the synchronous pulley 15 to dry the residual moisture on the surface of the electrode foil. After the electrode foil is dried, it continues to move and then moves through the limiting groove 4 to the bottom of the pickling tank 1 to contact the pickling liquid. Then the electrode foil begins to be pickled. Then the electrode foil rises to the bottom of the water outlet pipe 18 connected to the external water source and is rinsed with the pickling liquid on the surface of the electrode foil through the nozzle 20. Then the staff can take out the electrode foil and replace it with a new electrode foil.

[0036] In summary, this invention, through the cooperation of the water pump 22, water outlet pipe 18, fan 14, rotating rod 13, nozzle 20, filter plate 3, partition plate 2, and limiting groove 4, allows the device to pre-spray and dry the electrode foil during acid pickling, thereby cleaning the surface contaminants. Then, the electrode foil is immersed in the pickling liquid. This effectively solves the problems of contaminants adhering to the electrode foil surface reducing the pickling effect and the pickling liquid potentially injuring nearby personnel during spray pickling. Furthermore, the cooperation of the water outlet pipe 18, nozzle 20, and fan 14 allows the device to rinse the surface of the electrode foil after pickling, thereby cleaning the residual pickling liquid. This effectively solves the problems of inconvenience in cleaning residual pickling liquid after pickling and the potential harm to workers from the pickling liquid during electrode foil processing.

The patent protection scope of this utility model is determined by the claims. Similarly, any equivalent structural changes made based on the description and drawings of this utility model should also be included within the protection scope of this utility model.
