Description

Technical Field

[0001] This application relates to the field of battery processing technology, and in particular to a dynamic detection device for electrode winding. Background Technology

[0002] Electrodes are made by coating metal foil with materials such as active materials, conductive agents and binders. Electrode processing includes steps such as coating, drying and rolling. Rolling is the last step in electrode processing, which involves winding the processed electrode into a roll to facilitate subsequent battery assembly and transportation.

[0003] In related technologies, to facilitate the timely detection of appearance defects such as wrinkles, material loss, gaps, or even tears on the electrode sheet, a collection mechanism, including an industrial camera, is typically installed on the winding device. The industrial camera is positioned above the electrode sheet, and while the electrode sheet is being wound, the camera takes pictures at a preset shooting frequency. These pictures are then analyzed using image processing software to identify whether any appearance defects exist on the electrode sheet.

[0004] However, as the diameter of the electrode increases after winding, the distance between the industrial camera and the electrode surface also increases. This causes the viewing angle of the industrial camera to change, which in turn affects the resolution of the image captured by the industrial camera. Consequently, defects on the electrode surface may be blurred or missed, affecting the accuracy of the detection by the collection mechanism. Utility Model Content

[0049] The accompanying drawings illustrate specific embodiments of this application, which will be described in more detail below. These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0050] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0051] In related technologies, in order to facilitate the timely detection of appearance defects such as wrinkles, material loss, gaps, or even tears on the electrode sheet, a collection mechanism is usually set on the winding device. The collection mechanism includes an industrial camera, which is set above the electrode sheet. When the electrode sheet is wound, the industrial camera takes pictures at a preset shooting frequency to capture image information of the electrode sheet surface. These images are then analyzed by advanced image processing software. The software uses specific algorithms to identify abnormal features in the images, thereby determining whether there are appearance defects on the electrode sheet.

[0052] However, as the diameter of the electrode increases after winding, the distance between the industrial camera and the electrode surface also increases. This causes the viewing angle of the industrial camera to change, which in turn affects the resolution of the image captured by the industrial camera. As a result, defects on the electrode surface may be blurred or missed, affecting the accuracy of the collection mechanism's detection. In addition, due to the change in viewing angle, the industrial camera may not be able to completely cover the entire surface of the electrode, causing defects in some areas to go undetected, further reducing the reliability of the detection system.

[0053] The technical solution of this application and how the technical solution of this application solves the above-mentioned technical problems are described in detail below with specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of this application will now be described with reference to the accompanying drawings.

[0054] Combination Figure 1 and Figure 2 This application provides an electrode winding dynamic detection device, comprising:

[0055] The frame 100 is used to install the winding device 110 for winding the counter electrode sheet;

[0056] Collection mechanism 200, used to collect appearance defects of electrode sheets;

[0057] An adjustment mechanism 300 is mounted on the frame 100, and a collection mechanism 200 is mounted on the adjustment mechanism 300. The adjustment mechanism 300 is used to drive the collection mechanism 200 to move, so as to adjust the relative position between the collection mechanism 200 and the winding device 110.

[0058] In this embodiment, the frame 100 includes a support platform 120 and a connecting seat 130. There are two support platforms 120, which are opposite to each other and spaced apart. The connecting seat 130 is disposed between the two support platforms 120. One side of the connecting seat 130 is fixed to one of the support platforms 120, and the other side of the connecting seat 130 is fixed to the other support platform 120. In other embodiments, the shape and structure of the frame 100 can be adapted as needed. For example, the frame 100 can include a platform and support columns disposed under the platform and located at the four corners of the platform.

[0059] In this embodiment, the winding device 110 includes a spool 111 and a drive member. One end of the spool 111 is inserted through and rotatably connected to one of the support platforms 120. The drive member is disposed inside the support platform 120 and is used to drive the spool 111 to rotate. By fixing the head of the electrode sheet to the spool 111, the spool 111 can drive the electrode sheet to wind around the spool 111 when it rotates. The drive member is a motor, which can drive the spool 111 to rotate, thereby winding the electrode sheet. In other embodiments, the two ends of the spool 111 can be inserted through and rotatably connected to two support platforms 120 respectively.

[0060] In this application, by employing an adjustment mechanism 300, the adjustment mechanism 300 can drive the collection mechanism 200 to move, thereby adjusting the relative position between the collection mechanism 200 and the electrode. When the electrode is wound by the winding device, as the diameter of the electrode roll 112 formed after winding increases, the adjustment mechanism 300 can drive the collection mechanism 200 away from the electrode, thereby ensuring that the collection mechanism 200 always maintains the same distance from the electrode, preventing changes in the distance between the electrode and the collection mechanism 200 from affecting the accuracy of detection, and indirectly improving the detection accuracy of the collection mechanism 200. When the electrode thickness is different, the adjustment mechanism 300 drives the collection mechanism 200 to move, thereby adjusting the relative positions of the collection mechanism 200 and the electrode, ensuring that the adjustment mechanism 300 has the same distance for positions with different thicknesses, thereby further improving the detection accuracy of the collection mechanism 200.

[0061] Combination Figures 1 to 3 The adjustment mechanism 300 includes a support plate 310, a connecting plate 320, and a lifting assembly 330. The support plate 310 is mounted on the frame 100. The connecting plate 320 is slidably mounted on the support plate 310 along the height direction of the support plate 310. The collection mechanism 200 is mounted on the connecting plate 320. The lifting assembly 330 is mounted on the support plate 310. The lifting assembly 330 is used to drive the connecting plate 320 to rise and fall, so that the connecting plate 320 drives the collection mechanism 200 to rise and fall.

[0062] In this embodiment, a first slide rail 311 is provided on the support plate 310 along the height direction of the support plate 310, and a first slider 321 is provided on the connecting plate 320 and slidably connected to the first slide rail 311. The connecting plate 320 is slidably disposed on the support plate 310 through the first slide rail 311 and the first slider 321. In other embodiments, a groove can also be provided on the support plate 310 along the height direction of the support plate 310. By engaging and slidably connecting the first slider 321 in the groove, the connecting plate 320 can also be slidably disposed on the support plate 310 through the groove and the first slider 321.

[0063] In this embodiment, the support plate 310 is disposed on the support platform 120 of the frame 100. The support plate 310 is configured as a right triangle. By configuring the support plate 310 as a right triangle, the right triangle support plate 310 has better strength, thereby indirectly improving the support effect of the support plate 310 on the connecting plate 320 and the collecting mechanism 200. The connecting plate 320 is slidably disposed on one of the right-angled sides of the right triangle support plate 310. In other embodiments, the shape of the support plate 310 can be adaptively adjusted as needed, for example, the support plate 310 can be configured as a rectangle.

[0064] In this application, when it is necessary to adjust the distance between the collecting mechanism 200 and the winding device 110, the connecting plate 320 is driven to rise and fall by the lifting component 330, so that the connecting plate 320 drives the collecting mechanism 200 to rise and fall, thereby adjusting the distance between the collecting mechanism 200 and the winding device 110. When the electrode sheet on the roll 111 is continuously wound, by adjusting the height of the collecting mechanism 200, the collecting mechanism 200 and the electrode sheet always maintain the same distance, thereby indirectly improving the detection accuracy of the collecting mechanism 200.

[0065] Combination Figures 1 to 3 The lifting assembly 330 includes a lifting screw 331 and a lifting motor 332. The lifting screw 331 is rotatably mounted on the support plate 310, and the connecting plate 320 is threadedly connected to the lifting screw 331. The lifting motor 332 is mounted on the support plate 310 and is used to drive the lifting screw 331 to rotate.

[0066] In this embodiment, the lifting screw 331 is rotatably disposed inside the first slide rail 311, and the lifting motor 332 is fixedly disposed at one end of the first slide rail 311. One end of the lifting screw 331 is connected to the drive end of the lifting motor 332. The first slider 321 can be directly threaded to the lifting screw 331, or a threaded sleeve threaded to the lifting screw 331 can be provided on the first slider 321, so that the connecting plate 320 is threadedly connected to the lifting screw 331 through the first slider 321 and the threaded sleeve.

[0067] In this application, when the height of the collection mechanism 200 needs to be adjusted, the lifting screw 331 is driven to rotate by the lifting motor 332. Because the first slider 321 is slidably mounted on the first slide rail 311, the first slider 321 will not rotate with the rotation of the lifting screw 331. This allows the first slider 321 to move on the lifting screw 331, enabling the first slider 321 to drive the connecting plate 320 to rise and fall, thereby driving the collection mechanism 200 to rise and fall. The use of the lifting screw 331 to drive the collection mechanism 200 provides precise position control, ensuring that the collection mechanism 200 can accurately reach the predetermined position. The lifting screw 331 drive has high transmission accuracy and stability, ensuring that the collection mechanism 200 runs smoothly during the lifting process, reducing vibration and shaking, thereby preventing the collection mechanism 200 from being affected in the detection, and indirectly improving the clarity and stability of the detection image. In addition, the lifting screw 331 drive has good self-locking performance, reliably maintaining the position of the collection mechanism 200 when the power is off or the drive stops, avoiding device position deviation due to unexpected situations.

[0068] In other embodiments, the lifting assembly 330 may be replaced by one of an electric cylinder, a pneumatic cylinder, and a hydraulic cylinder.

[0069] Combination Figure 1 , Figure 4 and Figure 5 The adjustment mechanism 300 also includes a drive assembly 340. The connecting plate 320 includes a first connecting part 322 and a second connecting part 323. The first connecting part 322 is slidably disposed on the support plate 310, and the second connecting part 323 is slidably disposed on the first connecting part 322. The collection mechanism 200 is disposed on the second connecting part 323, and the drive assembly 340 is disposed on the first connecting part 322. The drive assembly 340 is used to drive the second connecting part 323 to move, so that the second connecting part 323 drives the collection mechanism 200 to move.

[0070] In this embodiment, the first connecting part 322 is rectangular, and the rectangular first connecting part 322 is arranged along the axis perpendicular to the scroll 111.

[0071] In this embodiment, a second slide rail 324 is provided on the first connecting portion 322 along the length direction of the first connecting portion 322, and a second slider 325 is provided on the second connecting portion 323 and slidably connected to the second slide rail 324. The second connecting portion 323 is slidably disposed on the first connecting portion 322 through the second slide rail 324 and the second slider 325. In other embodiments, a groove can also be provided on the first connecting portion 322 along the length direction of the first connecting portion 322. By engaging and slidably connecting the second slider 325 in the groove, the second connecting portion 323 can also be slidably disposed on the first connecting portion 322 through the groove and the second slider 325.

[0072] In this application, the second connecting part 323 is driven to move on the first connecting part 322 by the driving component 340, so that the second connecting part 323 can drive the collecting mechanism 200 to move further. When the diameter of the electrode on the reel 111 gradually increases, the position of the collecting mechanism 200 can be further adjusted by the driving component 340, so that the collecting mechanism 200 can detect the electrode at different positions, thereby improving the detection range of the collecting mechanism 200.

[0073] Combination Figure 1 , Figure 4 and Figure 5 The sliding direction of the second connecting part 323 is perpendicular to the sliding direction of the first connecting part 322.

[0074] In this embodiment, the sliding direction of the first connecting part 322 is the z-axis direction of the spatial rectangular coordinate system, and the sliding direction of the second connecting part 323 is the x-axis direction of the spatial rectangular coordinate system.

[0075] In this application, when the drive assembly 340 drives the second connecting part 323 to move, the second connecting part 323 can drive the collecting mechanism 200 to move along the axis perpendicular to the roll 111. When the diameter of the electrode roll 112 gradually increases, by adjusting the position of the collecting mechanism 200, the collecting mechanism 200 can detect different positions of the electrode roll 112 with a larger diameter. Furthermore, when the electrode roll 112 shakes during high-speed winding, by continuously adjusting the position of the collecting mechanism 200, the collecting mechanism 200 can adapt to the shaking electrode roll 112, thereby further improving the detection accuracy of the collecting mechanism 200.

[0076] Combination Figure 1 , Figure 4 and Figure 5 The drive assembly 340 includes a drive screw 341 and a drive motor 342. The drive screw 341 is rotatably mounted on the first connecting part 322, and the second connecting part 323 is threadedly connected to the drive screw 341. The drive motor 342 is mounted on the first connecting part 322 and is used to drive the drive screw 341 to rotate.

[0077] In this embodiment, the drive screw 341 is rotatably disposed inside the second slide rail 324, and the drive motor 342 is fixedly disposed at one end of the second slide rail 324. One end of the drive screw 341 is connected to the drive end of the drive motor 342. The second slider 325 can be directly threaded to the drive screw 341, or a threaded sleeve threaded to the drive screw 341 can be provided on the second slider 325, so that the second connecting part 323 is threadedly connected to the drive screw 341 through the second slider 325 and the threaded sleeve.

[0078] In this application, when the position of the collecting mechanism 200 needs to be adjusted, the drive motor 342 drives the drive screw 341 to rotate. Because the second slider 325 is slidably mounted on the second slide rail 324, the second slider 325 will not rotate with the rotation of the drive screw 341. This allows the second slider 325 to move on the drive screw 341, enabling the second slider 325 to drive the second connecting part 323 to move, thereby causing the second connecting part 323 to drive the collecting mechanism 200 to move. Using the drive screw 341 provides precise position control, ensuring that the collecting mechanism 200 can accurately reach the predetermined position. The drive screw 341 has high transmission accuracy and stability, ensuring that the collecting mechanism 200 runs smoothly during the driving process, reducing vibration and shaking, thereby preventing the detection of the collecting mechanism 200 from being affected, and indirectly improving the clarity and stability of the detection image. In addition, the drive screw 341 has good self-locking performance, reliably maintaining the position of the collecting mechanism 200 when the power is off or the drive stops, avoiding device position deviation due to unexpected situations.

[0079] In other embodiments, the drive assembly 340 may be replaced by one of an electric cylinder, a pneumatic cylinder, and a hydraulic cylinder.

[0080] Combination Figure 1 , Figure 4 and Figure 5 There are two support plates 310, which are arranged opposite each other on both sides of the frame 100. A connecting plate 320 is slidably arranged on both support plates 310. The collecting mechanism 200 is arranged between the second connecting parts 323 of the two connecting plates 320. A lifting component 330 is arranged on both support plates 310.

[0081] In this embodiment, two support plates 310 are respectively set on two support platforms 120 of the frame 100; in other embodiments, the number of support plates 310 and lifting components 330 can be adjusted as needed. For example, four sets of support plates 310 and lifting components 330 are set along the circumference of the frame 100, and the first connecting part 322 is driven to lift the collection mechanism 200 through the four sets of lifting components 330.

[0082] In this application, by employing two support plates 310 and two lifting components 330, the connecting plates 320 on both support plates 310 can support the collection mechanism 200, thereby indirectly improving the support strength of the connecting plates 320 for the collection mechanism 200. The two lifting components 330 can drive the collection mechanism 200 to rise and fall, thereby indirectly improving the stability of the collection mechanism 200 during rising and falling, preventing the collection mechanism 200 from shaking during rising and falling, and thus indirectly improving the detection accuracy of the collection mechanism 200.

[0083] Combination Figure 1 , Figure 6 and Figure 7 In the vertical direction, the two sides of the collecting mechanism 200 are rotatably connected to the second connecting parts 323 on both sides.

[0084] In this application, by rotatably connecting the two sides of the collection mechanism 200 to two second connecting parts 323 respectively, and rotating the collection mechanism 200 in the vertical direction, one side connecting plate 320 is driven to rise by a lifting component 330 on one side, and the other side connecting plate 320 is driven to fall by a lifting component 330 on the other side. This causes the two lifting components 330 to tilt the collection mechanism 200. When one side of the electrode roll 112 is thicker than the other side, or when the tension of the two sides of the electrode roll 112 is inconsistent, by driving the collection mechanism 200 to tilt, the tilted collection mechanism 200 can be directly facing the electrode, thereby indirectly improving the detection accuracy of the collection mechanism 200. Furthermore, by driving the collection mechanism 200 to tilt by the two lifting components 330, the tilted collection mechanism 200 can detect the side of the electrode roll 112, thereby further increasing the detection range of the collection mechanism 200.

[0085] Combination Figure 1 , Figure 6 and Figure 7 A ball joint assembly 210 is provided between one side of the collecting mechanism 200 and one of the second connecting parts 323. One side of the collecting mechanism 200 is rotatably connected to one of the second connecting parts 323 through the ball joint assembly 210.

[0086] In this embodiment, the ball joint assembly 210 includes a seat 211 and two balls 212. There are two seats 211 and two balls 212. The seats 211 are disposed on the second connecting part 323 and the balls 212 are disposed on the collecting mechanism 200. The seats 211 are provided with grooves 213. The two balls 212 are respectively engaged and rotatably connected in the two grooves 213.

[0087] In this application, by adopting the ball joint assembly 210, one side of the collection mechanism 200 can be omnidirectionally connected to the second connecting part 323, thereby increasing the rotation range of the collection mechanism 200 and preventing the one side of the collection mechanism 200 from getting stuck when rotating on the second connecting part 323.

[0088] Combination Figure 1 , Figure 6 and Figure 7 A bearing assembly 220 is provided between the other side of the collecting mechanism 200 and another second connecting part 323, and the other side of the collecting mechanism 200 is rotatably connected to the other second connecting part 323 through the bearing assembly 220.

[0089] In this embodiment, the bearing assembly 220 includes two ball bearings, each of which includes an outer ring and an inner ring. The inner ring passes through and is rotatably connected to the outer ring. The outer ring is disposed on the second connecting part 323, and the inner ring is disposed on the other side of the collecting mechanism 200. The rotation axis of the inner ring within the outer ring is perpendicular to the rotation axis of the scroll 111.

[0090] In this application, by adopting the bearing assembly 220, the smoothness of rotation of the other side of the collection mechanism 200, which is rotatably mounted on the second connecting part 323, can be improved, thereby preventing the other side of the collection mechanism 200 from getting stuck when rotating on the second connecting part 323.

[0091] Combination Figure 1 and Figure 8 The adjustment mechanism 300 also includes a moving component 350. The support plate 310 is slidably connected to the frame 100. The moving component 350 is disposed on the frame 100 and is used to drive the support plate 310 to move, so that the support plate 310 drives the collection mechanism 200 to move.

[0092] In this embodiment, a third slide rail 140 is provided on the frame 100 along the length direction of the scroll 111, and a third slider 312 is provided on the support plate 310 and slidably connected to the third slide rail 140. The support plate 310 is slidably mounted on the frame 100 through the third slide rail 140 and the third slider 312. In other embodiments, a slide groove can also be provided on the frame 100 along the length direction of the frame 100. By engaging and slidably connecting the third slider 312 in the slide groove, the support plate 310 can also be slidably mounted on the frame 100 through the slide groove and the third slider 312.

[0093] In this application, by adopting the movable component 350, the movable component 350 can drive the support plate 310 to move on the frame 100, so that the support plate 310 can drive the collection mechanism 200 to move further, thereby further adjusting the relative position between the collection mechanism 200 and the winding device 110, so that the collection mechanism 200 can further detect the electrode at different positions, thereby further increasing the detection range of the collection mechanism 200.

[0094] Combination Figure 1 and Figure 8 The sliding direction of the support plate 310 is perpendicular to the sliding direction of the second connecting part 323, and the sliding direction of the support plate 310 is perpendicular to the sliding direction of the first connecting part 322.

[0095] In this embodiment, both support plates 310 are slidably mounted on the frame 100. Two moving components 350 are provided, and the two moving components 350 correspond one-to-one with the two support plates 310. The sliding direction of the support plate 310 is the y-axis direction of the spatial rectangular coordinate system.

[0096] In this application, by making the sliding direction of the support plate 310 perpendicular to the sliding directions of the first connecting part 322 and the second connecting part 323, the two support plates 310 can drive the collection mechanism 200 to move along the axial direction of the roll 111. When the winding device 110 has two rolls 111 and there is a positional deviation between the two rolls 111, the position of the collection mechanism 200 is adjusted by the moving component 350, so that the collection mechanism 200 can be relative to any position of the electrode roll 112 along the axial direction of the roll 111. When there are bulges or other phenomena on the surface of the electrode roll 112 that affect the position recognition and determination, the support plate 310 is driven to move by the moving component 350, so that the moving component 350 can drive the collection mechanism 200 to avoid the uneven surface position, thereby improving the detection range of the collection mechanism 200 and improving the detection accuracy of the collection mechanism 200.

[0097] Combination Figure 1 and Figure 8 The moving component 350 includes a moving screw 351 and a moving motor 352. The moving screw 351 is rotatably mounted on the frame 100. The support plate 310 is threadedly connected to the moving screw 351. The moving motor 352 is mounted on the frame 100 and is used to drive the moving screw 351 to rotate.

[0098] In this embodiment, the movable screw 351 is rotatably disposed inside the third slide rail 140, and the movable motor 352 is fixedly disposed at one end of the third slide rail 140. One end of the movable screw 351 is connected to the movable end of the movable motor 352. The third slider 312 can be directly threaded to the movable screw 351, or a threaded sleeve that is threaded to the movable screw 351 can be provided on the third slider 312, so that the third connecting part is threaded to the movable screw 351 through the third slider 312 and the threaded sleeve.

[0099] In this application, when the position of the collecting mechanism 200 needs to be adjusted, the moving motor 352 drives the moving screw 351 to rotate. Because the third slider 312 is slidably mounted on the third slide rail 140, the third slider 312 will not rotate with the rotation of the moving screw 351. This allows the third slider 312 to move on the moving screw 351, enabling the third slider 312 to drive the support plate 310 to move, which in turn drives the collecting mechanism 200 to move. The use of the moving screw 351 provides precise position control, ensuring that the collecting mechanism 200 can accurately reach the predetermined position. The movement of the moving screw 351 has high transmission accuracy and stability, ensuring that the collecting mechanism 200 runs smoothly during movement, reducing vibration and shaking, thereby preventing any impact on the detection of the collecting mechanism 200 and indirectly improving the clarity and stability of the detection image. In addition, the moving screw 351 has good self-locking performance, reliably maintaining the position of the collecting mechanism 200 when power is off or movement stops, avoiding device position deviation due to unexpected situations.

[0100] Combination Figure 1 , Figure 9 and Figure 10 The collection mechanism 200 includes a mounting plate 230 and a camera 240. The mounting plate 230 is disposed on the adjustment mechanism 300, and at least one camera 240 is disposed on the mounting plate 230.

[0101] In this embodiment, one side of the connecting plate 320 is rotatably connected to one of the second connecting parts 323 via a ball joint assembly 210, and the other side of the connecting plate 320 is rotatably connected to another second connecting part 323 via a bearing assembly 220; the camera 240 is a high-speed camera, and three cameras 240 are provided, which are located on the same straight line and are spaced apart in the middle of the mounting plate 230.

[0102] In this application, a high-speed camera is used to detect defects on the electrode sheet. The high-speed camera can capture images at an extremely high frame rate, ensuring clear and continuous images even when the electrode sheet is moving rapidly. This effectively avoids detection errors caused by motion blur. High-speed cameras are typically equipped with high-resolution sensors, which can accurately identify minute defects on the electrode sheet, such as wrinkles, material loss, gaps, and tears, improving the sensitivity and accuracy of detection. Combined with image processing software, high-speed cameras can achieve automated defect identification and classification, greatly improving detection efficiency and reducing manual intervention. The real-time feedback function of the high-speed camera can immediately issue an alarm and trigger corresponding processing mechanisms when a defect is detected, helping to correct problems in the production process in a timely manner and preventing defective products from flowing into subsequent processes. This significantly improves product quality and production efficiency, and reduces production costs and safety risks.

[0103] Combination Figure 1 , Figure 9 and Figure 10 The collecting mechanism 200 also includes a light source 250, at least one of which is provided. The light source 250 is disposed on the mounting plate 230 and is used to irradiate the electrode.

[0104] In this embodiment, the light source 250 is a high-flicker frequency conversion light source. The light source 250 is elongated and there are two elongated light sources 250. The two light sources 250 are respectively located on both sides of the three cameras 240, and the two light sources 250 are opposite to the edge of the mounting plate 230.

[0105] In this application, when a high-speed camera detects electrode defects, a high-flicker frequency conversion light source is used to illuminate the electrode. The high-flicker frequency conversion light source can provide high-frequency pulse light, ensuring that each frame of the image can obtain uniform and sufficient illumination under the high frame rate shooting of the high-speed camera, thereby significantly improving the image clarity and contrast. The fast flicker characteristic of this light source 250 can effectively avoid motion blur caused by the rapid movement of the electrode, ensuring that defect features can be accurately captured. At the same time, the high brightness and stability of the high-flicker frequency conversion light source helps to highlight the small defects on the electrode surface, such as wrinkles, material loss, gaps and tears, further improving the accuracy and reliability of defect detection.

[0106] Combination Figure 1 , Figure 9 and Figure 10 The collecting mechanism 200 also includes a ranging element 260, at least one ranging element 260 is provided, the ranging element 260 is disposed on the mounting plate 230, and the ranging element 260 is used to detect the distance between itself and the electrode.

[0107] The ranging device 260 includes at least one follow-up ranging device 261 and at least one positioning ranging device 262. Both the follow-up ranging device 261 and the positioning ranging device 262 are mounted on the mounting plate 230. The follow-up ranging device 261 is used to adjust the direction to detect the distance between various positions of the electrode and the electrode. The positioning ranging device 262 is used to detect the distance between the electrode and the same position.

[0108] In this embodiment, the follow-up rangefinder 261 is a follow-up high-frequency laser rangefinder, and one follow-up high-frequency laser rangefinder is provided. The follow-up high-frequency laser rangefinder is located between two of the three high-speed cameras. The positioning rangefinder 262 is a positioning high-frequency laser rangefinder, and six positioning high-frequency laser rangefinders are provided. Three of the six positioning high-frequency laser rangefinders are located on one side of the three high-speed cameras, and the other three positioning high-frequency laser rangefinders are located on the other side of the three high-speed cameras.

[0109] In this application, a follow-up high-frequency laser rangefinder and a positioning high-frequency laser rangefinder are used. The follow-up high-frequency laser rangefinder can track changes in the electrode surface in real time, thereby dynamically adjusting the position of the camera 240 through the adjustment mechanism 300 to ensure that the camera 240 is always aligned with the electrode surface, thus adapting to the continuous changes in the roll diameter during the electrode winding process. The positioning high-frequency laser rangefinder provides high-precision distance measurement. For example, when multiple positioning high-frequency laser rangefinders detect different distances, the relative position of the mounting plate 230 and the electrode is adjusted according to the adjustment mechanism 300 to ensure that the camera 240 can accurately focus when in a fixed position, improving the image clarity and resolution. This combined use not only improves the accuracy and reliability of defect detection, but also enhances the adaptability and flexibility of the system, effectively solving the problem of changes in the viewing angle and focal length of the camera 240 caused by changes in the electrode roll diameter 112, ensuring that defects on the electrode surface can be identified and processed in a timely and accurate manner.

[0110] Combination Figure 1 and Figure 11 The electrode winding dynamic detection device also includes a computer control mechanism 400, which is connected to the adjustment mechanism 300. The computer control mechanism 400 is used to control the adjustment mechanism 300 according to the detection results of the adjustment mechanism 300.

[0111] In this embodiment, the computer control mechanism 400 includes a chassis 410, buttons 420, and a display 430. Buttons 420 are disposed on the chassis 410, and the display 430 is disposed on the chassis 410. The display 430 can display whether there is a defect in the electrode. The display 430 can also display the distance between the electrode and the follow-up high-frequency laser rangefinder and the positioning high-frequency laser rangefinder. When there is a defect in the electrode, the display 430 can also display defect photos and other information.

[0112] In this embodiment, for example, when the positioning high-frequency laser rangefinder detects that the actual distance between the mounting plate 230 and the electrode is greater than or less than the preset distance, the lifting component 330 can be controlled by the button 420, or the lifting component 330 can be automatically controlled by the controller, so that the lifting component 330 drives the connecting plate 320 to rise and fall, thereby adjusting the distance between the mounting plate 230 and the electrode to the preset distance.

[0113] For example, when several of the positioning high-frequency laser rangefinders detect that the distance between them and the electrode is greater than the distance between the remaining positioning high-frequency laser rangefinders and the electrode, the two lifting components 330 drive the two second connecting parts 323 to lift and lower, so that the two sides of the mounting plate 230 rotate on the two second connecting parts 323 respectively, thereby tilting the mounting plate 230 so that the mounting plate 230 is opposite to the electrode.

[0114] For example, if some of the positioning high-frequency laser rangefinders fail to detect the electrode, and the remaining high-frequency laser rangefinders detect a gap between the electrode and the rangefinder, a positional deviation may occur between the high-speed camera and the electrode. In this case, the drive assembly 340 and the moving assembly 350 can be controlled by the button 420 or the controller to move the mounting plate 230 horizontally, thereby adjusting the relative position between the high-speed camera and the electrode so that the high-speed camera and the electrode are aligned. With the computer control mechanism 400, there is no need to manually adjust the relative position between the collection mechanism 200 and the electrode, saving manpower and improving the automation level of the electrode winding dynamic detection device.

[0115] The electrode winding dynamic detection device provided in this application, when it is necessary to adjust the relative position between the camera 240 and the electrode on the roll 111, drives the lifting screw 331 to rotate via the lifting motor 332, causing the first connecting part 322 to move along the length direction of the lifting screw 331. This causes the first connecting part 322 to drive the second connecting part 323 to rise and fall, which in turn causes the second connecting part 323 to drive the camera 240 on the mounting plate 230 to rise and fall, thereby adjusting the distance between the camera 240 and the electrode. The device also drives the two lifting screws 331 to rotate via two lifting motors 332, causing one lifting screw 331 to drive one side of the mounting plate 230 to rise and the other lifting screw 331 to drive the other side of the mounting plate 230 to fall. This allows one side of the mounting plate 230 to rotate on one of the second connecting parts 323 via the ball joint assembly 210, and the other side of the mounting plate 230 to rotate on the other second connecting part 323 via the bearing assembly 220. At this time, the mounting plate 230 can tilt, thereby adjusting the angle of the camera 240. The motor 342 drives the drive screw 341 to rotate, causing the second connecting part 323 to move along the length direction of the drive screw 341 on the first connecting part 322. This causes the second connecting part 323 to move the camera 240 along the axis perpendicular to the roll 111, thereby further adjusting the relative position between the camera 240 and the electrode. The moving motor 352 drives the moving screw 351 to rotate, causing the support plate 310 to move along the length direction of the moving screw 351 on the frame 100, thus allowing the support plate 310 to move along the length direction of the moving screw 351. The camera 240 is moved along the axial direction of the reel 111, thereby further adjusting the relative position between the camera 240 and the electrode. By adjusting the relative position between the camera 240 and the electrode, the camera 240 can maintain a suitable distance and angle with the electrode in various situations, such as when the diameter of the electrode roll 112 increases, when the electrode roll 112 is swaying while winding, when the thickness on both sides of the electrode is different, or when the position of the electrode roll 112 changes. This ensures that the camera 240 always maintains a suitable focal length, thereby indirectly improving the accuracy of electrode defect detection.
