[0036] Reference below Figure 1-Figure 4 The notch detection device 100 of the blade 200 according to the first embodiment of the present invention will be described.

[0037] Figure 1 A schematic diagram of a blade notch detection device 100 according to an embodiment of the present invention is shown. The notch detection device 100 comprises a mounting base 10 and a detection assembly 30. The mounting base 10 is provided with a mounting position 101 for mounting a blade 200. The detection assembly 30 is movably mounted on the mounting base 10 and includes a camera 31 for photographing the blade 200.

[0038] In this embodiment, the notch detection device 100 uses a camera 31 to capture an image of the blade 200, obtaining a contour image of the cutting edge area. The notch detection device 100 then analyzes the contour features based on an image recognition algorithm to determine whether the blade 200 has a notch. Optionally, the notch detection device 100 in this embodiment of the present invention includes: an image recognition algorithm acquisition module, a comparison module, a judgment module, and a display module. The image recognition algorithm acquisition module acquires a real-time contour image of the blade; the comparison module compares the real-time contour image with an ideal contour image and uses the image recognition algorithm to determine the difference between the two. The judgment module determines whether the difference is within a set range: if the difference is within the set range, it indicates that the real-time contour image is close to the ideal contour image, and the blade is determined to have no notch. If the difference exceeds the set range, it indicates that the real-time contour image is not close to the ideal contour image, and the blade is determined to have a notch. The display module displays the judgment result and includes a display screen, an indicator light, and other components for visually displaying the judgment result. The image recognition algorithm used in this application can adopt a known solution in the prior art. The image recognition algorithm itself is not the core of this application and will not be described in detail here.

[0039] As mentioned in the background technology, some existing blade inspections use ultra-depth-of-field inspections, which require the blades to be inspected to be removed from the production line and placed under a microscope for manual observation and analysis. This method has many shortcomings: First, the inspection of the blades must be carried out when the production line is shut down, which affects production continuity and wastes time; second, the entire inspection process relies on manual operation, resulting in increased labor costs and the instability of the inspection results due to human observation errors; third, this inspection method can usually only perform random inspections on the blades, making it difficult to achieve continuous monitoring and unable to detect whether there are gaps in the blades in a timely manner, which may lead to a decline in cutting quality and affect the cutting accuracy and product consistency of lithium battery pole pieces.

[0040] In contrast, the notch detection device 100 of the present invention can perform online inspection without downtime, effectively improving inspection efficiency. It also identifies the blade 200's contour through image acquisition and analysis, improving inspection accuracy. Furthermore, the notch detection device 100 can monitor the blade 200 in real time, facilitating the timely detection of notch defects. This notch detection device not only monitors the life of the blade 200 but also provides early warning of blade wear, replacing manual inspection.

[0041] The distance between the detection assembly 30 and the mounting position 101 is adjustable to adjust the focal length of the camera 31. This facilitates adjustment of the focal length of the camera 31, ensuring accurate detection of the blade 200. Furthermore, the notch detection device 100 can adjust the relative position between the blade 200 and the camera 31 to accommodate different blade models and thicknesses, or to accommodate different camera models, ensuring clear and accurate contour information during image capture. This increases the flexibility of the notch detection device 100 and ensures reliable detection of the blade 200.

[0042] Optionally, the distance between the detection assembly 30 and the mounting position 101 is automatically adjusted by a first movable assembly. This approach enables rapid focal length adjustment, improving the automation of the notch detection device 100. Alternatively, the distance between the detection assembly 30 and the mounting position 101 can be manually adjusted to reduce manufacturing costs and simplify the device structure.

[0043] Further optionally, the analysis algorithm in the notch detection device 100 includes comparing the profile of the blade 200 captured in real time by the camera 31 with a preset profile. When a deviation is detected between the two and the deviation exceeds a set threshold, it is determined that a notch defect exists on the cutting edge of the blade 200.

[0044] According to some optional embodiments of the present invention, the notch detection device 100 further includes a first movable assembly mounted on the mounting base 10. At least one of the detection assembly 30 and the mounting position 101 is connected to the first movable assembly to adjust the distance between the detection assembly 30 and the mounting position 101.

[0045] In this embodiment, the first movable component can be used to adjust the relative position between the detection component 30 and the installation position 101, thereby adjusting the distance between the camera 31 and the blade 200 to adapt to blades 200 of different thicknesses or installation heights, thereby ensuring image acquisition clarity.

[0046] In some optional technical solutions, the first moving assembly is adapted to adjust the position of the mounting position 101. After the blade 200 is fixed to the mounting position 101, the first moving assembly can be used to move the blade 200, thereby adjusting the relative position between the blade 200 and the camera 31 to achieve focusing.

[0047] In some other optional technical solutions, the first moving component is suitable for adjusting the position of the detection component 30 to achieve focusing.

[0048] Optionally, the first movable component is suitable for adjusting the positions of the mounting position 101 and the detection component 30. On the one hand, by adjusting the relative position between the two, the focus of the camera 31 is achieved to ensure clear image acquisition; on the other hand, after the blade 200 is fixed at the mounting position 101, the blade 200 can be stopped at different positions according to different cutting requirements, and then the focus of the blade 200 can be achieved by adjusting the position of the detection component 30, thereby improving the flexibility and adaptability of detection.

[0049] Specifically, the detection component 30 and the installation position 101 are arranged along the first direction. In this way, the detection component 30 and the installation position 101 can be close to or away from each other in the first direction.

[0050] More specifically, the first moving component includes: a first linear motor, the first linear motor has a first mover that moves along a first direction, and one of the detection component 30 and the mounting position 101 is connected to the first mover. The movement of the first mover drives the detection component 30 or the mounting position 101 to move synchronously, thereby achieving relative position adjustment. For example, the detection component 30 is connected to the first mover, and after the blade 200 is installed to the mounting position 101, focusing is achieved by adjusting the position of the detection component 30. In another example, the mounting position 101 is connected to the first mover, and after the blade 200 is installed in place, focusing adjustment is achieved by adjusting the position of the blade 200 itself.

[0051] Alternatively, the first moving component includes two independent second linear motors, each of which has a second mover that moves along the first direction, and the detection component 30 and the mounting position 101 are each connected to a second mover. The dual-motor structure makes the position adjustment of the detection component 30 and the mounting position 101 more flexible and can be controlled separately, which is conducive to flexible adaptation to more cutting and adjustment requirements. For example, after the blade 200 is installed in the mounting position 101, the mounting position 101 can be moved by controlling the corresponding second mover, thereby adjusting the position of the blade 200 to adapt to different cutting requirements. Subsequently, by adjusting the other second mover connected to the detection component 30, the positioning of the detection component 30 relative to the blade 200 is achieved, thereby completing the focusing operation.

[0052] Optionally, the first moving assembly includes a drag chain and a drag chain frame, with the drag chain mounted within the drag chain frame. The first mover or the second mover is connected to the drag chain. For example, when the first mover or the second mover moves in a first direction, the drag chain moves accordingly, ensuring that it maintains a stable path during repeated movement, reducing wear and interference. The drag chain frame provides a securing and limiting function, preventing the drag chain from shifting or falling off during operation.

[0053] Further optionally, combined with Figure 1 and Figure 2The notch detection device 100 further includes a first guide assembly 52. ​​The first guide assembly 52 is conducive to improving the stability of the detection assembly 30 and the installation position 101 during the movement, so as to improve the focus stability of the camera 31.

[0054] Specifically, the first guide assembly 52 includes a first guide rail 521 and two first sliders 522. The first guide rail 521 extends along a first direction and is mounted on the mounting base 10. The two first sliders 522 engage with the first guide rails 521, respectively. The detection assembly 30 is connected to one of the first sliders 522, and the mounting position 101 is connected to the other first slider 522. The first moving assembly is connected to at least one first slider 522.

[0055] In the above technical solution, the two first sliders 522 can slide linearly along the first guide rail 521. The detection assembly 30 is connected to one of the sliders, and the mounting position 101 is connected to the other slider, which means that the two can move relative to or synchronously on the first guide rail 521. The first moving assembly is connected to at least one of the sliders, so that the first slider 522 can be driven to move the detection assembly 30 or the mounting position 101 in the first direction to achieve focal length adjustment or position matching.

[0056] For example, the first movable assembly is connected to a slider having a mounting position 101. By driving the slider, the blade 200 moves in a first direction, thereby adjusting its relative position with the detection assembly 30 and achieving focal length adjustment. Alternatively, the first movable assembly is connected to a slider having the detection assembly 30, so that the detection assembly 30 is driven to move to achieve focal length adjustment.

[0057] According to a further optional embodiment of the present invention, please combine Figure 1 and Figure 3 The detection assembly 30 and the mounting position 101 are arranged along the first direction. The notch detection device 100 further includes a second movable assembly 61 and a tool holder 63. The second movable assembly 61 is mounted on the mounting base 10. The tool holder 63 is connected to the second movable assembly 61 and is used to drive the tool holder 63 to move in the second direction. The mounting position 101 is located on the tool holder 63.

[0058] Reference Figure 3 The second direction can be a vertical direction. The second moving assembly 61 drives the blade holder 63 to move up and down along the second direction, thereby driving the blade 200 to move synchronously. Through the cooperation of the second moving assembly 61 and the blade holder 63, the position of the blade 200 in the vertical direction can be adjusted, thereby allowing the blade 200 to complete the cutting operation by moving up and down during the actual cutting process.

[0059] Optionally, the second moving assembly 61 includes a drive motor, which can be a linear motor, a servo motor, etc., for driving the tool holder 63 to move up and down.

[0060] In some optional embodiments, such as Figure 3 As shown, the notch detection device 100 further includes a knife holder 67 and a rotating assembly 65. The knife holder 67 is rotatably mounted on the knife frame 63, and the knife holder 67 forms a mounting position 101. The rotating assembly 65 is mounted on the knife frame 63 and is connected to the knife holder 67 to drive the knife holder 67 to rotate.

[0061] It's worth noting that the rotating assembly 65 controls the movement of the blade holder 67. During the actual cutting process, the rotating assembly 65 drives the blade holder 67 to rotate, which in turn drives the blade 200 to rotate. Simultaneously, the blade 200 moves downward in the second direction, effectively cutting the workpiece (e.g., a pole piece). In other words, the blade 200 simultaneously rotates and presses downward, and the two work together to complete the workpiece cutting process.

[0062] Further optionally, the rotating assembly 65 includes: a driving motor, a belt and a transmission wheel, etc. Specifically, the driving motor drives the transmission wheel to rotate, and the transmission wheel transmits power to the knife seat 67 through the belt, thereby rotating the knife seat 67 and the blade 200 thereon.

[0063] More optimally, the blade holder 63 is provided with a viewing window 631 facing the camera 31. This window 631 is arranged circumferentially and extends in an arc. Specifically, the blade 200 is mounted on the blade holder 63, and by rotating the blade holder 67, different portions of the blade 200 sequentially pass through the viewing window 631. The camera 31 then captures the exposed blade 200 through the viewing window 631. This helps improve the purity of the viewing angle and minimize interference.

[0064] In yet other optional embodiments, the notch detection device 100 further includes a second guide assembly 62, which includes a second guide rail 621 and a second slider 622. The second guide rail 621 extends along the second direction and is mounted on the mounting base 10. The second slider 622 engages with the second guide rail 621, and the tool holder 63 is connected to the second slider 622. The second movable assembly 61 is connected to the second slider 622.

[0065] In this technical solution, the cooperation between the second guide rail 621 and the second slider 622 improves the stability of the blade 200 in the second direction and reduces shaking and offset, which helps the focus of the camera 31 and improves the stability of cutting.

[0066] Optionally, the second guide assembly 62 includes a ball screw structure to guide and support the tool holder 63 to move smoothly along the second direction.

[0067] Further, if Figure 4 As shown, the gap detection device 100 further includes: a third moving assembly 71 and a frame 711, and the third moving assembly 71 is mounted on the mounting base 10. The frame 711 is connected to the third moving assembly 71, and the third moving assembly 71 is used to drive the frame 711 to move along the second direction. The detection assembly 30 is located on the frame 711.

[0068] Specifically, the third moving assembly 71 drives the detection assembly 30 in the second direction via the drive frame 711. The movement speed and direction of the detection assembly 30 are consistent with the movement speed and direction of the blade 200 during the cutting process. This allows for synchronous tracking of the blade 200's position changes during the cutting process, continuously monitoring the blade 200's status, and more timely acquisition of the blade 200's actual operating profile information, thereby improving detection efficiency.

[0069] Furthermore, the gap detection device 100 also includes a third guide assembly 72, which includes a third guide rail 721 and a third slider 722. The third guide rail 721 extends along the second direction and is mounted on the mounting base 10. The third slider 722 is engaged with the third guide rail 721, and the frame 711 is connected to the third slider 722. The third movable assembly 71 is connected to the third slider 722.

[0070] In this embodiment, the cooperation between the third guide rail 721 and the third slider 722 provides precise guidance for the movement of the frame 711 and the detection component 30 thereon, ensuring its stable operation along the second direction, effectively improving the focus stability during image acquisition, and ensuring accurate detection.

[0071] At the same time, the linear structure of the third guide rail 721 has a certain anti-eccentric load performance, which makes the detection component 30 more stable when following the movement of the blade 200, reducing the risk of image blur or misjudgment caused by vibration and shaking.

[0072] In some optional embodiments, the detection assembly 30 further includes a lens 32 and a steering cylinder 33. The lens 32 is positioned toward the mounting position 101. One end of the steering cylinder 33 is connected to the camera 31, and the other end is connected to the lens 32, so as to redirect light incident from the lens 32 toward the camera 31.

[0073] In this embodiment, by providing the steering cylinder 33, the camera 31 and the lens 32 can be connected in a non-coaxial manner, which helps to avoid interference from other structures and improve the rationality of the spatial layout.

[0074] In addition, the lens 32 and the camera 31 are optically connected through the steering cylinder 33, and the two can be disassembled and assembled independently, which is convenient for later maintenance, cleaning or replacement, thereby improving the maintenance convenience of the notch detection device 100.

[0075] More optimally, the detection assembly 30 further includes a light source 34 disposed at the lens 32 .

[0076] Here, light source 34 provides stable illumination for blade 200, ensuring sufficient light and no shadows during image acquisition, thereby improving image clarity and contour recognition accuracy. Furthermore, light source 34 evenly illuminates the edge of blade 200, enhancing the contrast between the edge of blade 200 and the background, which helps image processing algorithms extract features.

[0077] In addition, the light source 34 can provide constant lighting when the light in the production environment changes, thereby reducing the impact of external factors on image quality.

[0078] The slitting device according to the second embodiment of the present invention comprises: a notch detection device 100 for a blade 200 and a blade 200. The blade 200 is mounted on a mounting position 101. The notch detection device 100 is the notch detection device 100 of the first embodiment of the present invention.

[0079] It is worth noting that slitting equipment can be used for slitting films, foils, or other materials, including but not limited to longitudinal cutters, crosscutters, and slitting machines. Furthermore, it also includes electrode cutting machines specifically used for cutting electrodes during battery manufacturing. Once the type of slitting equipment is determined, the position of the notch detection device 100 and the mounting position 101 can be adaptively designed.

[0080] By providing the notch detection device 100 on the slitting equipment, it is advantageous to realize online monitoring of the status of the blade 200, ensure that the blade 200 has no notches, improve production efficiency, and enhance the quality of the final product.
