[0002] With the development of the times, new energy vehicles, energy storage systems and consumer electronics products have put forward extremely high requirements for the energy density, safety and cycle life of lithium-ion batteries. As a key material for the negative electrode current collector of lithium-ion batteries, the quality of electrolytic copper foil directly determines the performance and safety of the battery. The traditional copper foil penetration point detection currently used mainly involves passing the copper foil at a constant speed between a highly uniform linear backlight and a line scan camera. The camera performs continuous scanning synchronously based on the encoder trigger. Defect-free copper foil areas will block most of the light, forming a dark background, while penetration points and other defects allow more light to pass through, producing local bright spots in the image captured by the camera. While conventional copper foil penetration point detection methods can detect penetration points in copper foil, they cannot avoid contact with the desktop and are difficult to adjust the detection height and area. Therefore, a copper foil penetration point detection device is proposed to solve the above problems. Utility Model Content

[0009] 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.

[0010] Reference Figures 1-3This utility model provides an embodiment of a copper foil penetration point detection device, including an outer frame 1. The main function of the outer frame 1 is to support and fix all functional components of the device, ensuring orderly installation and preventing structural shaking due to loose components during detection, thus guaranteeing the stability of the copper foil penetration point detection process. A support plate 17 is fixedly connected to the outer side of the outer frame 1, which also fixes a baffle 16, providing a reliable mounting base for the baffle 16 and indirectly supporting the subsequent transmission arm 11. This prevents the transmission arm 11 from sagging due to insufficient support during operation, which would affect the detection process. Baffles 16 are fixedly connected to the top outer side of the support plate 17. The transmission arm 11 is mounted on its inner side, and a handle connecting seat 18 is mounted on its outer side. Only when the baffles 16 are firmly fixed to the support plate 17 can the transmission arm 11 be mounted on its inner side and the handle connecting seat 18 on its outer side. Each component provides a stable pivot point to prevent misalignment during rotation and ensure precise engagement of the transmission structure. A transmission arm 11 is rotatably connected to the inner side of the baffle 16. The transmission arm 11 is the power transmission rod of the device, which subsequently drives the adjusting screw 13 and the pressure head 14. This rotatable connection allows the transmission arm 11 to rotate flexibly around the pivot point on the baffle 16, ensuring that the pressure head 14 can be accurately moved to the detection position of the copper foil without wobbling. A handle connector 18 is rotatably connected to the outer side of the baffle 16. The handle connector 18 is the power component, connected to the handle 10 on one end and the linkage plate 21 on the other. Its rotatable connection to the baffle 16 allows it to rotate steadily with the handle 10 without wobbling, thus smoothly transmitting the force exerted by the operator on the handle 10 to the linkage plate 21. Both the movable plate 21 and the handle connecting seat 18 are rotatably connected to a linkage plate 21. The linkage plate 21 is the transmission link, transmitting the rotational force of the handle connecting seat 18 to the transmission arm 11. The rotatable connection ensures that the linkage plate 21 moves with the handle connecting seat 18 without jamming, allowing the force to be transmitted smoothly and ensuring the stable rotation of the transmission arm 11. The bottom inner side of the linkage plate 21 is rotatably connected to the outer side of the transmission arm 11, enabling precise rotation of the transmission arm 11 around the baffle 16 through this rotation point, ensuring that the pressure head 14 is precisely aligned with the copper foil to be tested without deviation. A hinge block 15 is fixedly connected to the outer side of the linkage plate 21, mainly to prevent misalignment at the connection point between the linkage plate 21 and the transmission arm 11. It can use its own structure to hold the transmission arm 11 in place, preventing them from going astray during rotation and ensuring the force is transmitted smoothly. The transmission direction is accurate and does not affect the detection. The bottom side of the hinge block 15 abuts against the outside of the transmission arm 11, without blocking the linkage plate 21 from driving the transmission arm 11 to rotate normally. It can also pull back in time when there is a slight tendency for misalignment between the two, ensuring accurate power transmission. The pressure head 14 can stably contact the copper foil for detection. The top and bottom sides of the transmission arm 11 are slidably connected with fixed shims 12. The fixed shims 12 are the fixed seats of the adjusting screw 13 and can be adjusted by sliding. The operator can move the position of the fixed shims 12 according to the detection position of the copper foil, and then adjust the position of the adjusting screw 13 and the pressure head 14, so that the device can measure copper foil of different sizes. The outer side of the fixed shims 12 is threaded with the adjusting screw 13. The threaded connection allows it to rotate up and down. The operator turns the adjusting screw 13.This allows the length of the pressure head 14 extending from the fixed pad 12 to be changed, thereby adjusting the distance between the pressure head 14 and the copper foil. This ensures that the pressure head 14 applies just the right amount of pressure to the copper foil, without damaging it or affecting the testing. The pressure head 14 is fixedly connected to the bottom of the adjusting screw 13. Driven by the transmission arm 11 and the adjusting screw 13, it presses against the copper foil and fixes it by applying pressure. The handle 10 is fixedly connected to the top of the handle connecting seat 18. When the operator turns the handle 10, it drives the handle connecting seat 18 to rotate, which in turn drives the pressure head 14 through the linkage plate 21, transmission arm 11, and other components. The pressure head 14 must be tightly connected to the handle connecting seat 18 for easy application of force and to ensure good control of the entire transmission process.

[0011] Reference Figures 3-5 Each of the outer frame 1 has a fixed support column 2 on its bottom side. The support column 2 extends downward from the bottom side of the outer frame 1, supporting the entire device and raising the outer frame 1 and the components above it for easier observation. Adjustment components are installed on the inner sides of the support column 2 and the outer frame 1. These adjustment components can adjust the tightness or component position inside the device according to the specifications of the copper foil and the testing requirements, allowing the device to better adapt to different testing conditions and ensuring that the copper foil is more securely fixed during testing, thus improving testing accuracy. The adjustment component includes an adjustment plate 6, which is the basic component of the adjustment component. Its shape and size are designed to provide a stable installation and sliding track for the slide rod 7, ensuring that the slide rod 7 can only move in the set direction and guaranteeing the normal operation of the adjustment component. The outer side of the adjustment plate 6 is fixedly connected to the inner side of the outer frame 1 and the support column 2. This fixing method connects the adjustment plate 6 with the outer frame 1 and the support column 2 into a whole, making the adjustment component a complete unit. The adjustment plate 6 is an integral part of the device and will not loosen or shift during adjustment, ensuring stable adjustment results. A sliding rod 7 is slidably connected to the inner side of the adjustment plate 6. The sliding rod 7 can slide back and forth within the adjustment plate 6, adjusting the overall length or tightness of the adjustment component by changing its position, thus adapting to copper foils of different widths or thicknesses. This ensures the copper foil is evenly stressed during testing. Limiting plates 8 are fixedly connected to the outer side of the sliding rod 7. The limiting plates 8 have a larger cross-section than the sliding rod 7. When the sliding rod 7 slides within the adjustment plate 6, the limiting plates 8 block it, preventing it from completely slipping out of the adjustment plate 6, ensuring the structural integrity of the adjustment component, and avoiding any impact on device use due to the sliding rod 7 falling off. A spring 9 is fixedly connected to the inner side of the sliding rod 7. The spring 9 can be compressed or stretched, storing elastic potential energy. When the external force disappears, the spring 9 returns to its original shape, driving the sliding rod 7 back to its initial position, causing the adjustment component to automatically reset.

[0012] Reference Figures 1-5All outer sides of the baffle 16 are threaded with bolts 19, which are threaded into the support plate 17. The bolts 19 securely fix the baffle 16 to the support plate 17 through the threads. This connection method is not only secure but also convenient for disassembly and adjustment. When the baffle 16 needs to be repaired or replaced, simply unscrew the bolts 19. The operation is simple. The outer side of the handle connecting seat 18 is rotatably connected with a rotating shaft 1 23 and a rotating shaft 22. The rotating shaft 1 23 and the rotating shaft 22 are the fulcrum for the rotation of the handle connecting seat 18. They can reduce the friction between the handle connecting seat 18 and other parts, making the rotation of the handle connecting seat 18 more flexible and smooth, and ensuring that the operator will not feel any jamming when turning the handle 10. The outer circumference of the rotating shaft 13 is rotatably connected to the inside of the baffle 16. 23. Connecting the handle connector 18 and the baffle 16 allows the handle connector 18 to rotate around the baffle 16, providing a central axis for rotation and ensuring a stable rotation trajectory. The second rotating shaft 22 is rotatably connected to the inside of the linkage plate 21. The second rotating shaft 22 is the connecting shaft between the handle connector 18 and the linkage plate 21, allowing the linkage plate 21 to swing with the rotation of the handle connector 18, while also allowing itself to rotate flexibly, reducing wear between the handle connector 18 and the linkage plate 21 and extending component life. A third rotating shaft 20 is rotatably connected to the outside of the baffle 16, providing a pivot point for the transmission arm 11, allowing the transmission arm 11 to rotate around the baffle 16, ensuring the transmission arm 11 receives power from the linkage plate 21. When force is received, the drive arm 11 moves along a preset trajectory, causing the pressure head 14 to move accurately. The outer circumference of the rotating shaft 20 is rotatably connected to the inner side of the transmission arm 11, providing a pivot point for the transmission arm 11, allowing it to rotate around the baffle 16. This ensures that when the transmission arm 11 receives force from the linkage plate 21, it moves along a preset trajectory, causing the pressure head 14 to move accurately. The outer circumference of the linkage plate 21 is rotatably connected to the rotating shaft 24, which connects the linkage plate 21 and the transmission arm 11, allowing them to rotate relative to each other. When the linkage plate 21 swings, the rotating shaft 24 smoothly drives the transmission arm 11 to rotate, preventing rigid collisions and protecting components. The outer circumference of the rotating shaft 24 is rotatably connected to the inner side of the transmission arm 11, and the rotating shaft 24 is connected to the linkage plate 21. Plate 21 and transmission arm 11 allow relative rotation. When the linkage plate 21 swings, it smoothly drives the transmission arm 11 to rotate via the rotating shaft 24, avoiding rigid collisions between them and protecting the components. Support columns 3 are fixedly connected to the outer side of the support column 2. The top side of the support column 3 is fixedly connected to the bottom side of the outer frame 1. The support column 3 obliquely connects the support column 2 and the outer frame 1, forming a triangular structure. Triangles have stability, and this design enhances the connection strength between the support column 2 and the outer frame 1, improves the load-bearing capacity of the entire device, and makes the device more stable during use. An extension column 4 is fixedly connected to the outer side of the bottom of the adjusting plate 6. The extension column 4 extends outward from the bottom of the adjusting plate 6, increasing the length of the bottom of the adjusting plate 6, allowing the adjusting component to better cooperate with other parts of the device.This also provides an installation position for the anti-slip pad 5, allowing it to function more stably. The anti-slip pad 5, made of rubber or other anti-slip materials, is fixedly connected to the bottom of the extension column 4. It increases the friction between the extension column 4 and the placement surface, preventing the device from sliding due to force during testing, ensuring the stability of the device's position during testing, and improving the accuracy of the test results.

[0013] Working principle: First, place the device on a flat working surface. The support column 2 at the bottom of the outer frame 1 will raise the entire device. At the same time, the anti-slip pad 5 on the bottom side of the extension column 4 will increase the friction with the placement surface to prevent the device from sliding. Then, according to the area of ​​the copper foil to be tested, adjust the adjustment components inside the outer frame 1 and the support column 2. The operator can push the slide rod 7 to slide inside the adjustment plate 6. The spring 9 inside the slide rod 7 will be compressed or stretched as the slide rod 7 moves until the slide rod 7 can fit against the edge of the copper foil. At this time, the limiting plate 8 on the outside of the slide rod 7 will prevent the slide rod 7 from slipping out of the adjustment plate 6. Finally, through the elastic force of the spring 9, the slide rod 7 will stably hold the copper foil and fix the copper foil in the preset detection position, laying a stable foundation for subsequent detection. Secondly, the operator holds the handle 10 on the top side of the handle connector 18 and rotates the handle 10 clockwise. The handle 10 will cause the handle connector 18 to rotate flexibly around the first pivot 23 on the outer side of the baffle 16. At the same time, the handle connector 18 drives the linkage plate 21 to swing through the second pivot 22. The linkage plate 21 then transmits the rotational force to the transmission arm 11 through the fourth pivot 24, causing the transmission arm 11 to rotate around the third pivot 20 on the inner side of the baffle 16. During the rotation of the transmission arm 11, the operator can adjust the height of the pressure head 14 by adjusting the adjusting screw 13 on the outer side of the fixed shim 12. Since the adjusting screw 13 is threadedly connected to the fixed shim 12, rotating the adjusting screw 13 can change its extension length, thereby controlling the height of the pressure head 14. The distance between the copper foil and the pressure head 14 ensures that the pressure head 14 precisely adheres to the surface of the copper foil and applies appropriate pressure, without damaging the copper foil, while ensuring the contact strength required for testing. At this time, the operator can determine whether there are penetration points in the copper foil by observing the shape of the copper foil after being pressed or by using other testing methods. After the copper foil penetration point test is completed, the operator releases the handle 10, and the slide bar 7 slides inside the adjustment plate 6, and the entire adjustment assembly returns to its initial state. At the same time, the handle connecting seat 18, the linkage plate 21, and the transmission arm 11 will also return to their original positions as the handle 10 is released, and the pressure head 14 detaches from the surface of the copper foil. Throughout the process, the bolts 19 between the baffle 16 and the support plate 17 and each rotating shaft always ensure that the components are firmly connected and rotate flexibly.

[0014] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
