Technical Field

[0001] This utility model relates to the technical field of electrolytic foil production equipment, specifically to an improved automatic material collection device for electrolytic foil. Background Technology

[0002] In the field of electronic equipment manufacturing, electrolytic foil is a key component of aluminum electrolytic capacitors. Its quality and production efficiency play a vital role in the development of the entire industry. Electrolytic foil is made from specially made high-purity aluminum foil through a series of complex processes. First, the surface area of ​​the aluminum foil is effectively expanded through electrochemical or chemical corrosion methods. Then, with the help of electrochemical formation, a high-performance oxide film is generated on its surface. Automatic material collection devices are required in the production process of electrolytic foil.

[0003] However, existing automatic foil collection devices still have some problems in use:

[0004] First, the existing device's guiding mechanism is not precise enough and cannot guide the electroformed foil stably and accurately. During the take-up process, the electroformed foil is prone to lateral deviation, resulting in uneven edges of the roll, or even wrinkles and damage.

[0005] Secondly, the tension directly affects the quality of the roll when the electrolytic foil is wound up. The tension control mechanism of the existing device is not sensitive enough. When the speed or thickness of the electrolytic foil changes, the tension cannot be adjusted in time, resulting in the roll being too tight or too loose. Utility Model Content

[0006] In order to solve the problems of insufficient guidance and insensitive tension adjustment in existing electroforming foil collection devices, the purpose of this utility model is to provide an improved automatic collection device for electroforming foil.

[0007] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: an improved automatic foil collecting device, comprising a support platform, a first bracket and a second bracket fixedly connected to the upper surface of the support platform, a first servo motor and a second servo motor fixedly connected to one side of the first bracket and the second bracket respectively, the output ends of the first servo motor and the second servo motor respectively passing through one side of the first bracket and the second bracket and fixedly connected to a first winding roller and a second winding roller, a housing fixedly connected to the upper surface of the support platform, a tension adjusting component provided in the inner cavity of the housing, a positioning seat provided on the upper surface of the tension adjusting component, a positioning shaft rotatably connected to the inner wall of the positioning seat, and a tension roller fixedly connected to the end of the positioning shaft, a guide component being provided on the inner cavity and outer surface of the tension roller.

[0020] 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.

[0021] Example: Figure 1-5 As shown, this utility model provides an improved automatic take-up device for electrolytic foil, including a support platform 1. A first bracket 8 and a second bracket 13 are fixedly connected to the upper surface of the support platform 1. A first servo motor 4 and a second servo motor 5 are fixedly connected to one side of the first bracket 8 and the second bracket 13, respectively. The output ends of the first servo motor 4 and the second servo motor 5 pass through one side of the first bracket 8 and the second bracket 13 and are fixedly connected to a first take-up roller 7 and a second take-up roller 6, respectively. One end of the first take-up roller 7 and the second take-up roller 6 are rotatably connected to the inner wall of the first bracket 8 and the second bracket 13, respectively. The first servo motor 4 and the second servo motor 5 drive the first take-up roller 7 and the second take-up roller 6 to rotate, thereby realizing the take-up operation of electrolytic foil.

[0022] A housing 12 is fixedly connected to the upper surface of the support platform 1. The inner cavity of the housing 12 is provided with a tension adjustment component 3. The tension adjustment component 3 enables rapid tension adjustment during material take-up. A positioning seat 11 is provided on the upper surface of the tension adjustment component 3. A positioning shaft 10 is rotatably connected to the inner wall of the positioning seat 11, and a tension roller 9 is fixedly connected to the end of the positioning shaft 10. The positioning seat 11 and the positioning shaft 10 cooperate to enable the tension roller 9 to rotate stably, ensuring that the formed foil is smoothly transmitted on the tension roller 9. At the same time, it provides reliable support for the tension roller 9 and ensures that its position is stable during adjustment. The inner cavity and outer surface of the tension roller 9 are provided with a guide component 2. The guide component 2 cooperates with the tension roller 9 and plays a guiding role during the transmission and winding of the formed foil, reducing the deviation of the formed foil and ensuring neat winding.

[0023] The guide assembly 2 includes a miniature DC motor 22, which is fixedly installed on one side of the tension roller 9. A protective cover 21 for use with the miniature DC motor 22 is fixedly installed on one side of the tension roller 9. The miniature DC motor 22 is fixedly installed inside the protective cover 21, which protects the miniature DC motor 22 from dust, impurities, etc., and extends the service life of the motor. The output end of the miniature DC motor 22 passes through one side of the tension roller 9 and is fixedly connected to a screw 24. The miniature DC motor 22 drives the screw 24 to rotate, and one end of the screw 24 is damped and rotated through the inner wall of the tension roller 9 to ensure the stability of the screw 24's rotation and effectively reduce the screw 24's self-rotation.

[0024] The outer surface of the screw 24 is threaded with a slider 26, and the outer surface of the slider 26 is fixedly connected with a moving block 25. The outer surface of the tension roller 9 is provided with a guide groove 27 that works with the moving block 25. The outer surface of the moving block 25 is slidably connected to the inner wall of the guide groove 27. The guide groove 27 guides and limits the moving block 25, ensuring that the moving block 25 and the guide ring 23 move smoothly along a straight line, thus improving the guiding accuracy. The side of the moving block 25 facing away from the slider 26 passes through the guide groove 27 and is fixedly connected with the guide ring 23. Under the action of the thread, the slider 26 moves, and then the moving block 25 drives the guide ring 23 to slide on the tension roller 9, thereby adjusting the position of the guide ring 23 to accommodate different widths of formed foil. The guide ring 23 is slidably sleeved on the outer surface of the tension roller 9. The two guide rings 23 are in direct contact with the formed foil and work together to guide the formed foil through position adjustment, reducing the offset during the take-up process and the unevenness of the coil edge.

[0025] The tension adjustment assembly 3 includes parallel support plates 31, which are fixedly installed on the inner wall of the housing 12. A cylinder 32 is fixedly installed on the upper surface of the support plate 31, providing a stable mounting base for the cylinder 32 and ensuring its stability during operation. Each output end of the cylinder 32 is fixedly connected to a connecting plate 33, and each upper surface of the connecting plate 33 is fixedly connected to a guide rod 34. The guide rod 34 has a cross-shaped cross section, providing good guidance and stability during movement, preventing wobbling and ensuring accurate height adjustment of the tension roller 9. The top of the guide rod 34 penetrates the housing 12 and is fixedly connected to the lower surface of the positioning seat 11. The cylinder 32 acts as a power source, extending and retracting to move the connecting plate 33 and guide rod 34 up and down, thereby adjusting the height of the positioning seat 11 and the tension roller 9. The two tension adjustment structures work together to quickly create a height difference between the two tension rollers 9. When the foil forming speed or thickness changes, the tension can be adjusted promptly, effectively improving the material collection effect of the collecting device.

[0026] Working principle: When the automatic take-up device starts working, the chemically formed foil that needs to be taken up is sequentially wound around the outer surface of the second take-up roller 6, the tension roller 9 and the first take-up roller 7.

[0027] At this time, the guide component 2 comes into play. According to the width of the formed foil, the micro DC motor 22 starts, and its output end drives the screw 24 to rotate in a damped manner on the inner wall of the tension roller 9. Since the outer surface of the screw 24 is threaded with a slider 26, the slider 26 will move along the length direction of the screw 24 when the screw 24 rotates.

[0028] When the slider 26 moves, the movable block 25, which is fixedly connected to it, slides in the guide groove 27, thereby driving the guide ring 23 on the side of the movable block 25 facing away from the slider 26 to move.

[0029] Because the guide ring 23 is slidably sleeved on the outer surface of the tension roller 9, the two guide rings 23 can be adjusted to a position that matches the width of the formed foil, thus providing precise guidance for the formed foil and preventing it from shifting during transmission.

[0030] Then, the first servo motor 4 and the second servo motor 5 are started respectively, and their output ends drive the first take-up roller 7 and the second take-up roller 6 to rotate, so as to wind the chemical foil onto the take-up roller and complete the material taking work.

[0031] During the process of the formed foil passing through the tension roller 9, the tension adjustment component 3 will adjust the tension according to the speed and thickness changes of the formed foil. When the tension needs to be adjusted, the cylinder 32 is started, and its output end drives the connecting plate 33 to move up and down. The connecting plate 33 then drives the guide rod 34 to move. The movement of the guide rod 34 will drive the positioning seat 11 to move up and down, and then drive the tension roller 9 to move up and down through the positioning shaft 10.

[0032] Because of the two sets of tension adjustment structures, the two tension rollers 9 can quickly form a height difference, thereby changing the tension of the foil and ensuring that it maintains a stable tension during the winding process.

[0033] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
