[0034] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.

[0035] Reference Figure 1 One embodiment of this application provides an electrode imaging device 10. In this embodiment, the electrode imaging device 10 includes a first guide roller 100, a second guide roller 200, and an imaging device 300; the second guide roller 200 is disposed below the first guide roller 100, and an electrode feeding channel extending vertically is formed between the first guide roller 100 and the second guide roller 200, that is, the electrode 400 feeds vertically between the first guide roller 100 and the second guide roller 200, and electrode tabs 410 are formed on both sides of the electrode 400; the imaging device 300 is disposed between the first guide roller 100 and the second guide roller 200, and when the electrode tab 410 is between the first guide roller 100 and the second guide roller 200, the imaging device 300 images the electrode tab 410.

[0036] In this embodiment, the second guide roller 200 is located directly below the first guide roller 100. When the electrode sheet 400 feeds, it is parallel to the vertical plane between the first guide roller 100 and the second guide roller 200. The electrode sheet 400 can feed downwards from the first guide roller 100 towards the second guide roller 200, and it can also feed upwards from the second guide roller 200 towards the first guide roller 100. This embodiment will be described using the example of the electrode sheet 400 moving downwards from the first guide roller 100 towards the second guide roller 200.

[0037] Reference Figure 2 During the production process, electrode 400 requires tension to ensure it can drive the driven guide roller. However, due to the back-cut notch at electrode 410, there is no tension at electrode 410. Therefore, during material feeding, electrode 410 is in a relaxed state. If the feeding plane is at an angle to the vertical plane, electrode 410 will sag, and the more inclined the feeding plane, the more severe the sag. When imaging is performed with electrode 410 sag, superimposed images will appear, making defect detection impossible.

[0038] In related technologies, the imaging of the tab 410 is usually performed on the surface of the guide roller. Due to the presence of the roller surface, pinhole defects on the electrode 400 cannot be detected, leading to a missed detection of a serious defect. Furthermore, as the electrode 400 is produced on the guide roller for extended periods, the edges of the electrode 400 and the tab 410 portion will wear scratches onto the guide roller surface. These scratches affect the distance measurement and detection of the tab 410, making it difficult to accurately locate the edge of the tab 410 and affecting the accuracy of the distance measurement. This embodiment addresses this by having the electrode 400 move vertically during imaging, thereby imaging the vertical tab 410. This avoids the tab 410 sagging during imaging and also eliminates the need for the roller surface during imaging, enabling pinhole detection with more accurate positioning.

[0039] It should be noted that there can be two imaging devices 300, with each device 300 positioned on one side of the electrode 400 to image the tabs 410 on both sides. Each imaging device 300 may include a camera, used to capture images of the tabs 410, thus completing the imaging of the tabs 410. To improve image quality, the imaging device 300 is positioned directly opposite the location the tabs 410 need to pass through, and the surface of the imaging device 300 may coincide with the feed surface of the electrode 400. When the tab 410 passes through the imaging area of ​​the imaging device 300, the imaging device 300 is controlled to capture an image of the tab 410.

[0040] In some embodiments, the imaging device 300 can be communicatively connected to an image analysis device, and the imaging device 300 can transmit the captured image of the tab 410 to the image analysis device. The image analysis device can analyze the image using a defect detection model, thereby completing the detection of the tab 410. Image analysis devices already possess mature technology, and will not be described in detail here.

[0041] According to the electrode tab imaging device 10 of this application, the electrode sheet 400 is made to move vertically by using the first guide roller 100 and the second guide roller 200, and then the imaging device 300 is used to image the vertical electrode sheet 400 between the first guide roller 100 and the second guide roller 200. Imaging is performed when the electrode tab 410 is vertical, avoiding contact between the electrode tab 410 and the roller surface. This enables the detection of pinhole defects and eliminates the ranging deviation caused by scratches on the roller surface to the electrode tab 410. It also avoids the ranging deviation caused by the drooping of the electrode tab 410. The defect detection is more comprehensive and more accurate.

[0042] Reference Figure 3In some embodiments of this application, the imaging device 300 may include a light-transmitting plate 310, a backlight (not shown in the figure), and a camera (not shown in the figure). The light-transmitting plate 310 is disposed between the first guide roller 100 and the second guide roller 200. When the electrode sheet 400 is fed, the electrode tab 410 passes through the light-transmitting plate 310. The backlight is disposed corresponding to the light-transmitting plate 310, and the light from the backlight is projected onto the light-transmitting plate 310. The camera is disposed corresponding to the light-transmitting plate 310, and the camera uses the backlight to image the electrode tab 410 passing through the light-transmitting plate 310.

[0043] In this embodiment, a backlight and a camera are respectively disposed on both sides of the light-transmitting plate 310. The light-transmitting plate 310 can be used to form an imaging area, and the camera is set with reference to the imaging area to image the imaging area. The backlight can use light to project onto the tabs 410 passing through the light-transmitting plate 310, thereby making the shape of the tabs 410 clearer, and the camera uses the light projection from the backlight to image.

[0044] Reference Figure 4 In some embodiments of this application, the light-transmitting plate 310 may include a first transparent plate 311 and a second transparent plate 312 facing each other. The first transparent plate 311 and the second transparent plate 312 are both disposed between the first guide roller 100 and the second guide roller 200, and a gap is formed between the first transparent plate 311 and the second transparent plate 312 to allow the tab 410 to pass through.

[0045] In some embodiments, the first transparent plate 311 and the second transparent plate 312 may both be made of high-transparency explosion-proof glass. Gaskets may also be provided on the two opposite sides of the first transparent plate 311 and the second transparent plate 312. The two gaskets are parallel to each other and have a certain interval to form a gap. When the electrode 400 feeds, the electrode tab 410 passes through the gap.

[0046] It should be noted that after the gap is made, the tab 410 is restricted by the first transparent plate 311 and the second transparent plate 312 on both sides and cannot shift to the sides, so it moves in the vertical direction to avoid the tab 410 tilting and causing detection deviation.

[0047] In some embodiments of this application, the imaging device 300 may further include a guide 320, which is disposed above the first transparent plate 311 and the second transparent plate 312. The guide 320 has a guide surface that extends into the gap. When the electrode 400 is feeding and the electrode tab 410 contacts the guide surface, the electrode tab 410 enters the gap along the guide surface.

[0048] In some embodiments, the guide surface can be curved or flat, and the guide surface extends at least partially to both sides of the gap. During the cutting process, the tab 410 may experience deformation such as warping or wrinkles. Therefore, this embodiment utilizes the guide member 320 to smooth out deformations such as warping and wrinkles on the tab 410, thereby allowing the tab 410 to enter the gap for imaging more smoothly.

[0049] In some embodiments of this application, the guide member 320 may include a first bent plate 321 and a second bent plate 322. The lower end of the first bent plate 321 is connected to the upper end of the first transparent plate 311, and the upper end of the first bent plate 321 extends in a first direction to form a first arc surface protruding toward the electrode 400. The lower end of the second bent plate 322 is connected to the upper end of the second transparent plate 312, and the upper end of the second bent plate 322 extends in a second direction to form a second arc surface protruding toward the electrode 400. The first arc surface and the second arc surface serve as guide surfaces.

[0050] It should be noted that the first direction and the second direction can be perpendicular to the feeding direction of the electrode 400, and the first direction and the second direction can be opposite; for example, the first direction can be the direction away from the second transparent plate 312, and the second direction can be the direction away from the first transparent plate 311.

[0051] In this embodiment, the first arc surface and the second arc surface are arranged opposite to each other. When the electrode 400 is transmitting, if the electrode tab 410 has deformations such as warping or wrinkles, the warped or wrinkled structures first contact the first arc surface or the second arc surface, and then enter the gap along the first arc surface or the second arc surface, thereby smoothing it out.

[0052] In some embodiments of this application, the imaging device 300 may further include an attitude adjustment component 330, which is connected to the guide member 320. The attitude adjustment component 330 is used to adjust the attitude of the guide member 320 to adjust the guiding direction of the guide member 320 to the tab 410.

[0053] In some embodiments, the attitude adjustment component 330 can be indirectly connected to the guide member 320 via the first transparent plate 311 and the second transparent plate 312. The attitude adjustment component 330 can be connected to the first transparent plate 311 and the second transparent plate 312, and the guide member 320 is fixedly connected to the first transparent plate 311 and the second transparent plate 312. The attitude adjustment component 330 can adjust the attitude of the guide member 320 by adjusting the attitude of the first transparent plate 311 and the second transparent plate 312.

[0054] In other embodiments, the attitude adjustment component 330 may also be directly connected to the guide 320 to directly adjust the attitude of the guide 320.

[0055] It should be noted that the guiding direction of the guide member 320 for the electrode tab 410 refers to the positional relationship between the electrode tab 410 and the gap after it slides into the gap along the guide member 320. Due to structural component assembly and other reasons, a certain angular deviation between the guide member 320 and the feeding plane of the electrode 400 is unavoidable after installation. Figure 5 As shown, after the tab 410 enters the gap, the tab 410 may not be parallel to the gap. Or... Figure 6 As shown, after the tab 410 enters the gap, it may not be centered in the gap. Both of these situations may cause the tab 410 to scrape against the first transparent plate 311 and the second transparent plate 312, causing secondary damage to the tab 410.

[0056] In this embodiment, the attitude adjustment component 330 can adjust the attitude of the guide 320 so that after the tab 410 enters the gap along the guide surface of the guide 320, the tab 410 is parallel to the gap and is located in the center of the gap.

[0057] Reference Figure 7 In some embodiments of this application, the attitude adjustment component 330 may include a base 331, a linear displacement slide 332, and an angle adjustment mechanism 333; the linear displacement slide 332 is slidably disposed on the base 331, and the sliding direction of the linear displacement slide 332 on the base 331 is perpendicular to the feeding surface of the electrode 400; the angle adjustment mechanism 333 is disposed on the linear displacement slide 332 and connected to the first transparent plate 310 and the second transparent plate 320, and the angle adjustment mechanism 333 is used to adjust the tilt angle of the first transparent plate 310 and the second transparent plate 320.

[0058] In this embodiment, the base 331 serves a supporting function. The linear displacement slide 332 can adjust the position of the gap. By adjusting the linear displacement slide 332, the tab 410 can be positioned in the center of the gap after entering it.

[0059] In some embodiments, the first transparent plate 310 and the second transparent plate 320 can be fixed by a fastener, the guide member 320 is fixedly connected to the first transparent plate 310 and the second transparent plate 320, and the angle adjustment mechanism 333 adjusts the angle between the first transparent plate 310 and the second transparent plate 320 and the feed surface of the electrode 400 by adjusting the posture of the fastener.

[0060] In some embodiments, the angle adjustment mechanism 333 may include a reference member, which is placed vertically. The fixing member can be connected to the reference member by multiple bolts. By adjusting the length of each bolt, the included angle between the reference member and the fixing member can be adjusted, thereby adjusting the posture of the fixing member, so that the tab 410 can be parallel to the gap after entering the gap.

[0061] In some embodiments of this application, the attitude adjustment component 330 may further include a machine base connecting seat 334, a base 331 slidably disposed on the machine base connecting seat 334, the base 331 sliding on the machine base connecting seat 334 in a horizontal direction, and the sliding direction being parallel to the feeding surface of the electrode 400.

[0062] In some embodiments, the machine base connecting seat 334 is disposed between the first guide roller 100 and the second guide roller 200. The machine base connecting seat 334 can be a crossbeam, and the upper end of the crossbeam can be a groove or a guide rail. The base 331 cooperates with the groove or guide rail to form a sliding pair.

[0063] In this embodiment, the base 331 slides on the machine tool connecting seat 334, which can adjust the overall position of the attitude adjustment component 330. This allows it to accommodate electrode sheets 400 of different widths or electrode tabs 410 of different widths.

[0064] One embodiment of this application also provides an electrode die-cutting system, which includes an electrode imaging device 10 according to any of the foregoing embodiments. The specific structure of the electrode imaging device 10 can be referred to the foregoing embodiments, and will not be repeated here.

[0065] According to the electrode die-cutting system of this application, imaging is performed when the electrode tab 410 is perpendicular, avoiding contact between the electrode tab 410 and the roller surface. This enables pinhole defect detection and eliminates the ranging deviation caused by scratches on the roller surface to the electrode tab 410. It also avoids ranging deviation caused by the drooping of the electrode tab 410, resulting in more comprehensive and accurate defect detection. Of course, since the electrode die-cutting system can adopt the technical solutions of the above embodiments, it also possesses corresponding technical effects.

[0066] Reference Figure 8 In some embodiments of this application, the electrode die-cutting system may further include a die-cutting device 20 and a correction device 30. The die-cutting device 20 is used to cut the electrode 400 to form tabs 410 on both sides of the electrode 400. The correction device 30 is located downstream of the die-cutting device 20 and upstream of the tab imaging device 10. The height of the correction device 30 is higher than that of the tab imaging device 10. The correction device 30 is used to correct the feeding direction of the electrode 400. The tab imaging device 10 receives the electrode 400 transmitted by the correction device 30 and images the tabs 410 in the electrode 400.

[0067] It should be noted that the feeding direction of the electrode 400 can be understood as the position of the electrode 400 along the axial direction of the guide roller. To ensure the accuracy of subsequent processes, it is necessary to ensure that the die-cut electrode 400 enters the subsequent processes in the correct posture. Typically, the alignment device 30 is positioned relatively high, and the electrode 400 before and after it feeds vertically or nearly vertically. Therefore, it is more convenient to set up the electrode tab imaging device 10 proposed in this application downstream of the alignment device 30. At the same time, since there is a change in the electrode 400 before and after the alignment device 30, the first guide roller 100 and the second guide roller 200 in this embodiment can isolate the electrode 400 from the alignment device 30. By correcting the feeding plane of the electrode 400 through the first guide roller 100 and the second guide roller 200, it is ensured that the electrode 400 will not undergo horizontal positional changes when feeding vertically. The die-cutting device 20 and the alignment device 30 are based on mature technologies, and will not be described in detail here.
