Description
Technical Field
[0001] This utility model relates to the field of trimming device technology, and in particular to an electrode foil edge trimming and collection device. Background Technology
[0002] Electrode foil is a key material in the manufacture of aluminum electrolytic capacitors. It is mainly used to store charge and is known as the "CPU" of aluminum electrolytic capacitors. Its performance directly affects the capacitor's core indicators such as capacity, loss and lifespan. Electrode foil can be divided into cathode foil and anode foil according to its function, into etched foil (increasing surface area through etching) and formed foil (forming an oxide film on the surface) according to its processing steps, and into low-voltage foil, medium-high voltage foil and ultra-high voltage foil according to its working voltage. When coating lithium-ion battery electrodes, electrode foil is prone to a crescent-shaped thick edge phenomenon, which affects subsequent rolling, winding and other processes. It is usually eliminated by cutting off the edge or adjusting process parameters (such as die pressure and slurry viscosity).
[0003] In the prior art, Chinese patent CN211941070U discloses an electrode foil cutting device for lithium battery production that facilitates fixed-distance cutting, enabling the unwinding and flattening of the electrode foil and preventing curling at the cut. Simultaneously, the drive disc rotates via the transmission between the gear teeth, thereby achieving fixed-distance cutting of the electrode foil by the cutter. The cutting distance can be adjusted by regulating the transmission ratio between the drive worm and the turbine. However, in practical applications, a crescent-shaped thick edge phenomenon easily occurs when the electrode foil is coated with lithium-ion battery electrodes. Currently, when this thick edge phenomenon occurs, workers mostly use scissors to trim the edges of the electrode foil, which is slow and prone to uneven cutting. Therefore, we disclose an electrode foil edge trimming and collection device. Summary of the Invention
[0004] In view of this, the purpose of this utility model is to propose an electrode foil edge trimming and collection device to solve the problem of slow processing efficiency when manually trimming the edges of electrode foil.
[0005] To achieve the above objectives, this utility model provides an electrode foil edge trimming and collection device, comprising two bases. A support frame and a first reel are fixedly connected to one side of the top of each base. The first reels on both sides are rotatably connected to their respective support frames. A motor is fixedly connected to the top of one support frame, and the output end of the motor is fixedly sleeved with the first reel. A connecting shaft is movably engaged in the middle of the first reel, and an electrode foil body is wound around the outer periphery of the connecting shaft. A belt assembly is fixedly sleeved at one end of each of the two first reels. A fixed... The frame has several limiting shafts rotatably connected to its top end, which are in contact with the electrode foil body. A movable tool holder is movably sleeved in the middle of the frame, with one end of the movable tool holder in contact with the electrode foil body. Connecting rings are fixedly connected to both ends of the first spool on one side of the frame. A second spool is movably sleeved on the outer wall of the connecting ring, and the outer wall of the second spool is wound with the edge material after cutting the electrode foil body. The outer wall of the connecting ring is a regular polygon. A cutting component is provided in the middle of the movable tool holder, which is used to cut the edge of the electrode foil body.
[0006] Preferably, there are four limiting axes, which are divided into two groups. The two groups of limiting axes are symmetrically distributed in pairs. The electrode foil body is located between the two groups of limiting axes, and the movable tool holder is located between the two groups of limiting axes.
[0007] Preferably, both ends of the first reel have limiting holes. The connecting shaft includes a limiting block, a sleeve ring, and a rotating shaft. The rotating shaft is sleeved on the middle of the sleeve ring and fixedly connected to one end of the sleeve ring. The limiting block is located between the sleeve ring and the rotating shaft and is fixedly connected to the rotating shaft and the sleeve ring on both sides respectively. The sleeve ring and the rotating shaft are sleeved on the first reel, and the limiting block is movably engaged with the limiting hole.
[0008] Preferably, a movable groove is provided on the other side of the base, and a connecting block is slidably connected in the movable groove. The top end of the connecting block extends to the outside of the base and is fixedly connected to the support frame. Several sets of limiting grooves are provided at the top end of the base, and a limiting frame is movably engaged in the limiting groove. A first spring and a connecting rod are fixedly connected in the middle of the limiting frame. The first spring is sleeved on the outside of the connecting rod. The connecting rod is slidably connected to the support frame. The first spring is fixedly connected to the support frame.
[0009] Preferably, the limiting frame is U-shaped, and the moving groove and the connecting block are both T-shaped.
[0010] Preferably, the cutting assembly includes several fixing slots opened in the middle of the movable tool holder, a second spring is fixedly connected to the top of the movable tool holder, a fixing rod is fixedly connected to the top of the second spring, one end of the fixing rod passes through the fixing frame and is movably engaged with the fixing slots, and the movable tool holder is a rectangular rod.
[0011] Preferably, the fixing rod is T-shaped, one end of the movable blade holder is fixedly connected to a pull plate, and the other end of the movable blade holder is fixedly connected to a blade, which fits against the edge of the electrode foil body to cut the edge of the electrode foil body.
[0012] The beneficial effects of this utility model are as follows: During the winding and unwinding process of the electrode foil body, the position of the electrode foil body is adjusted by the limiting shaft, so that the moving blade holder can be in contact with the electrode foil body during the winding and unwinding process, and the edge of the electrode foil body is trimmed neatly. When the first roll rotates, it drives the second roll to rotate through the connecting ring, so that the second roll is used to wind the edge waste material cut off from the electrode foil body, and completes the collection of the edge of the connecting ring, which facilitates the subsequent processing of the edge of the connecting ring. The base restricts the position of the connecting block and the support frame through a movable groove, allowing the support frame connected to one side of the first reel to move, facilitating the loading and unloading of the first reel. It also allows for the fitting of first reels of various sizes within the support frame, improving the device's practicality. The base restricts the position of the limiting frame through a limiting groove, which in turn restricts the position of the limiting frame through a connecting rod and a first spring. This locking of the limiting groove and the limiting frame fixes the position of the moving support frame, ensuring the stability of the first reel during operation. A fixing frame fixes the position of the second spring, which in turn fixes the position of the fixing rod. The fixing rod, passing through the fixing frame and engaging with the fixing groove, restricts the position of the movable tool holder. This allows the movable tool holder to adjust its position according to the width of the electrode foil to be cut, further enhancing its practicality. Attached Figure Description

[0018] like Figures 1-5 As shown, an electrode foil edge trimming and collection device includes two bases 1. A support frame 2 and a first reel 5 are fixedly connected to one side of the top of each base 1. The first reels 5 on both sides are rotatably connected to their respective support frames 2. A motor 3 is fixedly connected to the top of one support frame 2. The output end of the motor 3 is fixedly sleeved with the first reel 5. A connecting shaft 4 is movably engaged in the middle of the first reel 5. An electrode foil body 6 is wound around the outer periphery of the connecting shaft 4. Two first spools 5 are each fixedly fitted with a belt assembly 13 at one end. A fixing frame 19 is provided between the two bases 1. Several limiting shafts 20 are rotatably connected to the top of the fixing frame 19. The limiting shafts 20 are in contact with the electrode foil body 6. A movable tool holder 21 is movably fitted in the middle of the fixing frame 19. One end of the movable tool holder 21 is in contact with the electrode foil body 6. Connecting rings 16 are fixedly connected to both ends of the first spools 5 on one side of the fixing frame 19. A second spool 15 is movably fitted on the outer wall of the connecting ring 16. The outer wall of the second spool 15 is wound with the edge material after cutting the electrode foil body 6. The outer wall of the connecting ring 16 is a regular polygon. A cutting assembly is provided in the middle of the movable tool holder 21. The cutting assembly is used to cut the edge of the electrode foil body 6. There are four limiting shafts 20. The four limiting shafts 20 are divided into four sections. There are two sets of limiting shafts 20, symmetrically distributed in pairs. The electrode foil body 6 is located between the two sets of limiting shafts 20, and the movable knife holder 21 is located between the two sets of limiting shafts 20. Limiting holes are opened at both ends of the first reel 5. The connecting shaft 4 includes a limiting block, a sleeve ring, and a rotating shaft. The rotating shaft is sleeved on the middle of the sleeve ring and fixedly connected to one end of the sleeve ring. The limiting block is located between the sleeve ring and the rotating shaft, and its two sides are fixedly connected to the rotating shaft and the sleeve ring respectively. The sleeve ring and the rotating shaft are sleeved on the first reel 5, and the limiting block is movably engaged with the limiting hole. In use, the support frame 2 and the first reel 5 are fixedly connected to one side of the top of each of the two bases 1, so that the base 1 fixes the position of one side of the support frame 2, and the first reel 5 is rotatably connected to the top of each of the two bases 1. Within the corresponding support frame 2, a motor 3 is fixedly connected to the top of one side of the support frame 2. The output end of the motor 3 is fixedly sleeved with the first reel 5. A connecting shaft 4 is movably engaged in the middle of the first reel 5. The electrode foil body 6 is wound around the middle of the connecting shaft 4, which fixes the position of the motor 3 in the support frame 2. After the motor 3 starts, it drives the connecting shaft 4 to rotate through the first reel 5. This causes the connecting shaft 4 to unwind the electrode foil body 6 on one side of the base 1. Belt groups 13 are fixedly sleeved at one end of each of the two first reels 5. This allows the first reels 5 on both sides of the belt group 13 to simultaneously unwind and rewind the electrode foil body 6, preventing the electrode foil body 6 from being damaged by excessive tension and also preventing the electrode foil body 6 between the two first reels 5 from being too weak to cut. The electrode foil body 6 is cut by a fixed frame 19 positioned between two bases 1. Several limiting shafts 20 are rotatably connected to the top of the fixed frame 19, and these limiting shafts 20 are in contact with the electrode foil body 6. A movable blade holder 21 is movably sleeved in the middle of the fixed frame 19, with one end of the movable blade holder 21 in contact with the electrode foil body 6. This allows the limiting shafts 20 to adjust the position of the electrode foil body 6, ensuring that the movable blade holder 21 remains in contact with the electrode foil body 6 during its unfolding and rewinding process, thus trimming the edges of the electrode foil body 6 neatly. Connecting rings 16 are fixedly connected to both ends of a first spool 5 on one side of the fixed frame 19. A second spool 15 is movably sleeved on the outer wall of the connecting ring 16, and the outer wall of the second spool 15 is wound around the cut edge material of the electrode foil body 6. The outer wall of the connecting ring 16 is a regular polygon.When the first reel 5 rotates, it drives the second reel 15 to rotate via the connecting ring 16. This causes the connecting ring 16 to wrap around the cut edge of the electrode foil body 6, completing the collection of the edge of the connecting ring 16. This facilitates subsequent processing of the edge of the connecting ring 16 and allows for faster edge trimming of the electrode foil body 6. There are four limiting shafts 20, divided into two groups, symmetrically distributed in pairs. The electrode foil body 6 is located between the two groups of limiting shafts 20, and the moving tool holder 21 is also located between the two groups of limiting shafts 20, thus ensuring that the limiting shafts 20... The electrode foil body 6 can maintain a close fit with the movable tool holder 21. Limiting holes are provided at both ends of the first reel 5. The connecting shaft 4 includes a limiting block, a sleeve ring, and a rotating shaft. The rotating shaft is sleeved on the middle of the sleeve ring and fixedly connected to one end of the sleeve ring. The limiting block is located between the sleeve ring and the rotating shaft, and its two sides are fixedly connected to the rotating shaft and the sleeve ring respectively. The sleeve ring and the rotating shaft are sleeved on the first reel 5, and the limiting block is movably engaged with the limiting holes, allowing the first reel 5 and the connecting shaft 4 to rotate simultaneously after being sleeved.
[0019] As a preferred embodiment of this example, Figures 1-4As shown, a movable groove 7 is provided on the other side of the base 1. A connecting block 8 is slidably connected in the movable groove 7. The top of the connecting block 8 extends to the outside of the base 1 and is fixedly connected to the support frame 2. Several sets of limiting grooves 9 are provided at the top of the base 1. A limiting frame 10 is movably engaged in the limiting grooves 9. A first spring 11 and a connecting rod 12 are fixedly connected to the middle of the limiting frame 10. The first spring 11 is sleeved on the outside of the connecting rod 12. The connecting rod 12 is slidably connected to the support frame 2. The first spring 11 is fixedly connected to the support frame 2. The limiting frame 10 is U-shaped. The movable groove 7 and the connecting block 8 are both T-shaped. The cutting assembly includes several fixed grooves 18 opened in the middle of the movable tool holder 21. A second spring 14 is fixedly connected to the top of the movable tool holder 21. The top of the second spring 14 is fixedly A fixed rod 17 is connected, with one end of the fixed rod 17 passing through the fixed frame 19 and movably engaging with the fixed groove 18. The movable blade holder 21 is a rectangular rod, and the fixed rod 17 is T-shaped. A pull plate is fixedly connected to one end of the movable blade holder 21, and a blade is fixedly connected to the other end of the movable blade holder 21. The blade is attached to the edge of the electrode foil body 6 to cut the edge of the electrode foil body 6. A movable groove 7 is provided on the other side of the base 1, and a connecting block 8 is slidably connected in the movable groove 7. The top end of the connecting block 8 extends to the outside of the base 1 and is fixedly connected to the support frame 2. This allows the base 1 to restrict the position of the connecting block 8 and the support frame 2 through the movable groove 7, thereby allowing the support frame 2 connected to one side of the first roll 5 to move, facilitating the loading and unloading of the first roll 5, and allowing various sizes to be fitted inside the support frame 2. The first reel 5, sized to improve the practicality of the device, has several sets of limiting grooves 9 at the top of the base 1. A limiting frame 10 is movably engaged within each limiting groove 9. A first spring 11 and a connecting rod 12 are fixedly connected to the middle of the limiting frame 10. The first spring 11 is sleeved on the outside of the connecting rod 12, which is slidably connected to the support frame 2. The first spring 11 is fixedly connected to the support frame 2, allowing the base 1 to limit the position of the limiting frame 10 through the limiting grooves 9. Similarly, the support frame 2, through the connecting rod 12 and the first spring 11, limits the position of the limiting frame 10. This engagement of the limiting grooves 9 and the limiting frame 10 fixes the position of the support frame 2 after movement, ensuring the stability of the first reel 5 during operation. The U-shaped limiting frame 10 further enhances the device's practicality. After the limiting frame 10 is disconnected from the limiting groove 9, it can rotate around the connecting rod 12 at an angle that is offset from the arrangement of the limiting groove 9, thereby facilitating the movement of the support frame 2. Since both the moving groove 7 and the connecting block 8 are T-shaped, the connection between the moving groove 7 and the connecting block 8 is stable. Several fixing grooves 18 are provided in the middle of the moving tool holder 21. A second spring 14 is fixedly connected to the top of the moving tool holder 21, and a fixing rod 17 is fixedly connected to the top of the second spring 14. One end of the fixing rod 17 passes through the fixing frame 19 and is movably engaged with the fixing groove 18, allowing the fixing frame 19 to fix the position of the second spring 14, which in turn fixes the position of the fixing rod 17. Thus, after the fixing rod 17 passes through the fixing frame 19 and engages with the fixing groove 18, it restricts the position of the moving tool holder 21.This allows the movable tool holder 21 to be adjusted in position according to the width of the electrode foil body 6 to be cut, thus improving its practicality. The movable tool holder 21 is a rectangular rod, connected to a T-shaped fixing rod 17. One end of the movable tool holder 21 is fixedly connected to a pull plate, facilitating the use of the fixing rod 17 and the movable tool holder 21. The other end of the movable tool holder 21 is fixedly connected to a blade, which fits against the electrode foil body 6 to cut it, allowing the electrode foil body 6 to be cut by the blade of the movable tool holder 21.
