Description

Technical Field

[0001] This invention relates to the field of battery tab testing equipment technology, specifically to a battery tab testing equipment and its testing method. Background Technology

[0002] Battery tab testing equipment is a series of specialized devices used to test the performance and quality of battery tabs.

[0003] Currently, when inspecting battery tabs, images of the product are captured by a camera, and then deep learning algorithms and image processing technology are used to analyze and compare the images to automatically identify defects on the product and mark or remove them.

[0004] Existing cameras used for battery tab identification are generally fixed and cannot be adjusted in position or angle. This results in a large blind spot for detecting the entire tab, failing to meet the requirements for battery tab detection. Manual assistance is required, reducing efficiency. Furthermore, during tab transmission, the camera cannot effectively position the battery tabs to coordinate with the camera's position, leading to the detection of tabs of different sizes. This further increases the camera's blind spot and reduces accuracy. While multi-angle imaging and comparative analysis are used for battery tab detection, only one side is imaged, resulting in limited data for subsequent image analysis and comparison, increasing the likelihood of detection errors. Therefore, we propose a battery tab detection device and method. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a battery tab detection device and method. It solves the problems of fixed cameras used for battery tab identification, which cannot adjust their position and angle, resulting in a large blind spot for overall tab detection and failing to meet the requirements for battery tab detection. Furthermore, detecting battery tabs of different sizes increases the camera's blind spot and further reduces detection accuracy.

The upper connecting frame is installed on the detection equipment. Multiple bottom surface detection components are installed on the upper connecting frame through a transmission mechanism.

[0020] A method for detecting battery tabs using a battery tab detection device includes the following steps:

[0021] The battery is transferred through a transmission mechanism, allowing it to enter the testing equipment for imaging and testing. The sliding cover is opened, and the battery is transported to the pull transmission frame. The transmission mechanism moves the battery, and the clamping mechanism on the sliding cover ensures the stability of the battery movement and positions the battery.

[0022] The transverse track is activated, causing the second guide rail to slide along the first guide rail. As the second guide rail moves, the clamping connecting frame and the clamping gripper move accordingly until the clamping gripper is directly above the battery in the detection pull belt assembly. The sliding frame moves, causing the clamping connecting frame and the clamping gripper to move downwards. At this point, the two clamping grippers are at both ends of the battery and move towards each other to clamp the battery. Then, the transverse track is activated, causing the second guide rail to slide on the first guide rail. With the help of the sensors in the detection equipment, the battery is clamped and moved to the cell transport unit for transfer.

[0023] When the battery is clamped to the top of the placement rack by the clamping hand, the battery is lowered so that it first contacts and is squeezed by two transport positioning blocks to position the battery. Under the action of gravity, the battery contacts two contact frames. When the battery needs to be transferred, the placement rack pushes the battery upward to separate it from the contact frames. Then, the transport drive moves the placement rack so that the battery is between another set of transport positioning blocks and contact frames. When the placement rack moves downward to contact the contact frames, multiple batteries perform the above movements simultaneously and move at the same time to complete the transfer of the batteries.

[0024] When the battery is transferred through the cell transport unit, the battery passes through the first side detection unit. The side detection unit takes pictures of the battery and takes pictures of the side of the battery through the side detection component. At the same time, the first camera takes pictures of the side of the battery. The position of the first guide rod on the side detection mounting base is adjusted to detect the side of batteries of different sizes.

[0025] When the battery is directly under the sliding base, the image is taken through the sliding base. At the same time, multiple large-area detection components are used to take pictures and detect the battery tabs and the front. By rotating the angle of the large-area detection components, it is convenient to take pictures and detect different battery tabs of different sizes to effectively ensure the detection effect.

[0026] Under the action of the flipping moving frame, the flipping component is moved. The battery is fixed in the flipping component by the clamping mechanism. Then, the flipping component is rotated by the push cylinder to flip the battery, thereby flipping the tabs on the battery. Finally, the flipping moving frame transports the battery to the cell handling unit for transfer.

[0027] The positions of the electrode tail detection component and the third camera are adjusted on the first and second connecting frames to facilitate the shooting and detection of batteries of different sizes. A rotating mechanism is provided between the third camera and the second connecting frame. The angle of the electrode tail detection component is adjusted by the rotating mechanism to avoid the generation of blind spots and ensure the accuracy of detection.

[0028] The battery is clamped by the clamping unit on the positioning frame, which simultaneously positions the battery and the battery edge. This allows the third camera to effectively photograph and inspect the battery tail and the tabs. The fourth camera moves on the adjustment frame to ensure that the battery is under appropriate lighting, thus ensuring accurate and clear inspection.

[0029] By adjusting the bottom surface detection components to a suitable angle, the battery can be effectively inspected over a large area, avoiding blind spots and ensuring the effectiveness of the inspection. When the battery is transported to the top of the upper connecting frame by the cell transport unit, the battery is photographed by the bottom surface detection connecting frame. Multiple bottom surface detection components are used to perform large-area inspection of the battery, and then the inspected battery is transported through the transmission mechanism.

[0030] This invention discloses a battery tab detection device and method, which have the following beneficial effects:

[0031] 1. The battery tab detection device and its detection method use a side detection component on the side detection unit to photograph and detect the side of the battery. By adjusting the position of the first guide rod on the side detection mounting base, it is convenient to detect the side of batteries of different sizes, ensuring the accuracy of battery detection. Multiple large-area detection components on the large-area detection unit photograph and detect the battery tabs and the front, avoiding the generation of blind spots and ensuring the accuracy of detection. By rotating the angle of the large-area detection components, it is convenient to photograph and detect different battery tabs of different sizes, effectively ensuring the detection effect.

[0032] 2. The battery tab detection equipment and its detection method flip the battery by rotating the flipping component on the tab flipping unit, thereby flipping the tabs on the battery. Then, the battery is transported to the cell transport unit by the flipping moving frame for transfer, completing the multi-directional detection of the battery. This allows for more data analysis and comparison of subsequent images, improving the accuracy and effectiveness of the detection.

[0033] 3. The battery tab detection equipment and its detection method effectively detect the battery tail and tabs by adjusting the position of the tab tail detection component and the third camera on the tab tail detection unit. Adjusting the angle of the tab tail detection component avoids the generation of blind spots and ensures the accuracy of detection. By adjusting the bottom surface detection component on the bottom surface detection unit to a suitable angle, the battery can be effectively detected over a large area, avoiding blind spots and ensuring the effectiveness of detection.

[0049] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention are described clearly and completely. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0050] This application provides a battery tab detection device and method, which solves the problems of battery tab identification cameras being generally fixed and unable to adjust their position and angle, resulting in a large blind spot for overall tab detection and failing to meet the requirements for battery tab detection. Detecting battery tabs of different sizes further increases the camera's blind spot and reduces detection accuracy. Furthermore, while multi-angle images of the battery are taken and compared during tab detection, only one side of the battery is photographed, leading to insufficient data for subsequent image analysis and comparison, which can easily cause detection errors. The method addresses these issues by using two transport positioning blocks 737 and a contact frame 736 on the cell transport unit 73 to position the battery, and using a transport drive 733 to move the placement frame 735, thus transferring the battery.

[0051] The side of the battery is photographed and inspected by the side detection component 714 on the side detection unit 71. By adjusting the position of the first guide rod 712 on the side detection mounting base 713, it is convenient to inspect the side of batteries of different sizes and ensure the accuracy of battery inspection.

[0052] The battery tabs and front are photographed and inspected by multiple large-area inspection components 723 on the large-area inspection unit 72, avoiding the generation of blind spots and ensuring the accuracy of inspection. By rotating the angle of the large-area inspection component 723, it is convenient to photograph and inspect different battery tabs of different sizes, which can effectively ensure the inspection effect.

[0053] The battery is flipped by rotating the flipping component 743 on the tab flipping unit 74, thereby flipping the tabs on the battery. The battery is then transported to the cell transport unit 73 by the flipping moving frame 744 for transfer, completing the multi-directional detection of the battery. This allows for more data analysis and comparison of subsequent images, improving the accuracy and effectiveness of the detection.

[0054] By adjusting the positions of the electrode tail detection component 754 and the third camera 753 on the electrode tail detection unit 75, the battery tail and electrode are effectively photographed and detected. The angle of the electrode tail detection component 754 is adjusted to avoid the generation of blind spots and ensure the accuracy of detection.

[0055] By adjusting the bottom surface detection component 764 on the bottom surface detection unit 76 to a suitable angle, the battery can be effectively inspected on a large scale, avoiding blind spots and ensuring the effectiveness of the inspection.

[0056] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0057] This invention discloses a battery tab detection device and its detection method.

[0058] According to the appendix Figure 1-12 As shown, the device includes a testing device 1, a transmission mechanism 2, a testing pull belt assembly 3, multiple clamping manipulators 4, a testing frame 5, a barcode scanning pull belt assembly 6, and a battery cell testing assembly 7. The testing device 1 is connected to the transmission mechanism 2, which transmits the batteries so that they enter the testing device 1 for testing. The testing pull belt assembly 3 is located on one side of the testing device 1, above the transmission mechanism 2. The clamping manipulators 4 include a manipulator bracket 401 and a first guide rail 402, which are located on both sides of the testing device 1. The testing frame 5 and the barcode scanning pull belt assembly 6 are located inside the testing device 1. The battery cell testing assembly 7 is located inside the testing device 1.

[0059] The detection pull strap assembly 3 includes a pull strap bracket 301 that contacts the ground. The pull strap bracket 301 is provided with a pull transmission frame 303. By opening the sliding cover plate 302, the battery is placed on the pull transmission frame 303. The battery is moved by the transmission mechanism. At the same time, the clamping mechanism on the sliding cover plate 302 ensures the stability of the battery movement and positions the battery.

[0060] The clamping robot 4 includes a robot support 401 fixedly connected to the detection equipment 1. A second guide rail 404 is driven to the robot support 401. A clamping connecting frame 407 is fixedly connected to the end of the second guide rail 404. Two clamping grippers 408 are slidably connected to the clamping connecting frame 407. When the clamping grippers 408 are directly above the battery in the detection pull belt assembly 3, the longitudinal track 405 drives the sliding frame 406 to move, which in turn drives the clamping connecting frame 407 and the clamping grippers 408 to move downward. At this time, the two clamping grippers 408 are at both ends of the battery. The clamping drive 409 drives the transmission mechanism to start. Under the action of the transmission mechanism, the two clamping grippers 408 move towards each other to clamp the battery and make the battery clamped at the center position of the clamping connecting frame 407.

[0061] The barcode scanning pull belt assembly 6 is positioned directly opposite the inspection frame 5;

[0062] The cell detection assembly 7 is located between the detection frame 5 and the barcode scanning pull belt assembly 6. The cell detection assembly 7 includes multiple side detection units 71, large surface detection units 72, cell handling units 73, tab flipping units 74, tab tail detection units 75 and bottom surface detection units 76. The battery is positioned by two handling positioning blocks 737 and contact frame 736 on the cell handling unit 73. The placement frame 735 is moved by the handling drive 733, so that the battery can be transferred.

[0063] The side of the battery is photographed and inspected by the side detection component 714 on the side detection unit 71. By adjusting the position of the first guide rod 712 on the side detection mounting base 713, it is convenient to inspect the side of batteries of different sizes and ensure the accuracy of battery inspection.

[0064] The battery tabs and front are photographed and inspected by multiple large-area inspection components 723 on the large-area inspection unit 72, avoiding the generation of blind spots and ensuring the accuracy of inspection. By rotating the angle of the large-area inspection component 723, it is convenient to photograph and inspect different battery tabs of different sizes, which can effectively ensure the inspection effect.

[0065] The battery is flipped by rotating the flipping component 743 on the tab flipping unit 74, thereby flipping the tabs on the battery. The battery is then transported to the cell transport unit 73 by the flipping moving frame 744 for transfer, completing the multi-directional detection of the battery. This allows for more data analysis and comparison of subsequent images, improving the accuracy and effectiveness of the detection.

[0066] By adjusting the positions of the electrode tail detection component 754 and the third camera 753 on the electrode tail detection unit 75, the battery tail and electrode are effectively photographed and detected. The angle of the electrode tail detection component 754 is adjusted to avoid the generation of blind spots and ensure the accuracy of detection.

[0067] By adjusting the bottom surface detection component 764 on the bottom surface detection unit 76 to a suitable angle, the battery can be effectively inspected on a large scale, avoiding blind spots and ensuring the effectiveness of the inspection.

[0068] A sliding cover plate 302 is slidably connected to the pull belt bracket 301. The sliding cover plate 302 is located directly above the pull transmission frame 303. A pull connecting frame 304 is installed at the bottom of the pull transmission frame 303. The pull connecting frame 304 is fixedly installed on the pull belt bracket 301. A transmission mechanism is provided on the pull connecting frame 304, which drives the pull transmission frame 303 to move. A clamping mechanism is provided on the pull transmission frame 303.

[0069] The battery is clamped and positioned by a clamping mechanism. The battery is placed on the pull transmission frame 303 by opening the sliding cover 302. The battery is moved by the transmission mechanism. At the same time, the clamping mechanism on the sliding cover 302 ensures the stability of the battery movement and positions the battery.

[0070] The pull belt bracket 301 is located on one side of one of the clamping manipulators 4. The manipulator bracket 401 of the clamping manipulator 4 is connected to a transverse track 403. The output end of the transverse track 403 is fixedly connected to the second guide rail 404. The first guide rail 402 is fixedly installed on the manipulator bracket 401. The second guide rail 404 is slidably connected to the outer peripheral wall of the first guide rail 402. Under the action of the first guide rail 402, the movement of the second guide rail 404 is relatively stable.

[0071] When it is necessary to clamp and move the battery in the detection pull belt assembly 3, the transverse track 403 is activated to drive the second guide rail 404 to slide along the first guide rail 402. As the second guide rail 404 moves, the clamping connecting frame 407 and the clamping hand 408 move accordingly until the clamping hand 408 is directly above the battery in the detection pull belt assembly 3.

[0072] A sliding frame 406 is slidably connected to the outer peripheral wall of the second guide rail 404. The sliding frame 406 is fixedly connected to the clamping connection frame 407. A longitudinal track 405 is provided on the side of the second guide rail 404. The output end of the longitudinal track 405 is fixedly connected to the sliding frame 406. The sliding frame 406 is connected to a clamping drive 409 through the clamping connection frame 407. The clamping drive 409 is fixedly installed on the clamping connection frame 407. A transmission mechanism is provided on the clamping connection frame 407. The clamping drive 409 is connected to the transmission mechanism. The end of the transmission mechanism is fixedly connected to the clamping gripper 408.

[0073] When the second guide rail 404 moves to the appropriate position along the first guide rail 402, the longitudinal track 405 drives the sliding frame 406 to move, which in turn drives the clamping connecting frame 407 and the clamping hand 408 to move downward. At this time, the two clamping hands 408 are at both ends of the battery. The clamping drive 409 drives the transmission mechanism to start. Under the action of the transmission mechanism, the two clamping hands 408 move towards each other to clamp the battery and make the battery clamped at the center position of the clamping connecting frame 407.

[0074] Then, the longitudinal track 405 is started, causing the sliding frame 406 to drive the clamping connecting frame 407 to move upward and clamp the battery upward. At this time, the transverse track 403 is started, causing the second guide rail 404 to slide on the first guide rail 402. With the help of the sensor set in the detection device 1, the battery is clamped and moved to the cell transport unit 73, and then transported through the cell transport unit 73.

[0075] The clamping handle 408 is positioned directly above the cell handling unit 73. The cell handling unit 73 includes a handling connecting frame 731 fixedly installed on the testing equipment 1. A fixed frame 732 and a handling drive 733 are fixedly connected to the top end face of the handling connecting frame 731. A drive mechanism is connected to the end of the handling drive 733. Multiple handling cylinders 734 are installed on the drive mechanism of the handling drive 733. A placement frame 735 is fixedly installed at the output end of the handling cylinder 734. Multiple sets of handling positioning blocks 737 are fixedly connected to the top end face of the placement frame 735. A contact frame 736 is fixedly connected to the inner wall of the fixed frame 732. Each set of handling positioning blocks 737 is located on both sides of the contact frame 736.

[0076] When the battery is clamped to the top of the placement rack 735 by the clamping hand 408, the battery is lowered so that it first contacts and is squeezed by the two transport positioning blocks 737 to position the battery. Under the action of gravity, the battery contacts the two contact racks 736.

[0077] When the battery needs to be transferred, the placement rack 735 pushes the battery upward to separate it from the contact rack 736. Then, the transport drive 733 drives the placement rack 735 to move, so that the battery is between another set of transport positioning blocks 737 and the contact rack 736. When the placement rack 735 moves downward, so that the battery contacts the contact rack 736, multiple batteries perform the above movements at the same time, and the transfer of the battery is completed simultaneously.

[0078] The two ends of the cell handling unit 73 pass through two side detection units 71 respectively. The side detection unit 71 includes a base plate 711 fixedly connected to the detection device 1. A first guide rod 712 and a second guide rod 715 are fixedly connected to the base plate 711. Multiple side detection mounting seats 713 are installed on the inner wall of the first guide rod 712. A side detection assembly 714 is installed between the side detection mounting seats 713. A first camera 716 is installed on the second guide rod 715. The first camera 716 is located between the two side detection mounting seats 713.

[0079] When the battery is transferred through the cell transport unit 73, the battery passes through the first side detection unit 71, which takes pictures of the battery. The side detection component 714 takes pictures of the side of the battery, and the first camera 716 takes pictures of the side of the battery. By adjusting the position of the first guide rod 712 on the side detection mounting base 713, it is convenient to detect the side of batteries of different sizes and ensure the accuracy of battery detection.

[0080] The cell handling unit 73 passes through the large-area detection unit 72. The large-area detection unit 72 includes a third guide rod 721 fixedly connected to the detection equipment 1. A large-area detection mounting base 722 and a sliding base 726 are fixedly installed on the inner wall of the third guide rod 721. A large-area detection mounting frame 724 is fixedly connected between the large-area detection mounting bases 722. A plurality of first rotating seats 725 are provided on the bottom end face of the large-area detection mounting frame 724.

The second camera 727 is located at the center of the plurality of large-area detection components 723.

[0081] The battery is transported by the cell transport unit 73. When the battery is directly below the sliding seat 726, the sliding seat 726 takes pictures. At the same time, multiple large-area detection components 723 take pictures and detect the battery tabs and front side, avoiding the generation of blind spots and ensuring the accuracy of detection. By rotating the angle of the large-area detection components 723, it is convenient to take pictures and detect different battery tabs of different sizes, which can effectively ensure the detection effect.

[0082] The cell handling unit 73 is located on one side of the tab flipping unit 74. The tab flipping unit 74 includes a flipping connecting frame 741 fixedly installed on the testing equipment 1. Multiple flipping moving frames 744 are installed on the bottom end face of the flipping connecting frame 741. Multiple pushing cylinders 742 are installed on the flipping connecting frame 741. A flipping component 743 is fixedly connected to the output end of the pushing cylinder 742. A clamping mechanism is provided on the flipping component 743.

[0083] Under the action of the flipping moving frame 744, the flipping component 743 is moved. The battery is fixed in the flipping component 743 by the clamping mechanism. Then, the flipping component 743 is rotated by the pushing cylinder 742, flipping the battery and flipping the tabs on the battery. The battery is then transported to the cell transport unit 73 by the flipping moving frame 744 for transfer, completing the multi-directional detection of the battery. This allows for more data for subsequent image analysis and comparison, improving the accuracy and effectiveness of the detection.

[0084] The cell handling unit 73 passes through the tab tail detection unit 75. The tab tail detection unit 75 includes a first connecting frame 751 and a second connecting frame 752 fixedly connected to the detection equipment 1. The first connecting frame 751 and the second connecting frame 752 are respectively equipped with a tab tail detection component 754 and two third cameras 753. The positions of the tab tail detection component 754 and the third cameras 753 can be adjusted on the first connecting frame 751 and the second connecting frame 752 to facilitate the shooting and detection of batteries of different sizes. A rotating mechanism is provided between the third camera 753 and the second connecting frame 752. The angle of the tab tail detection component 754 can be adjusted by the rotating mechanism to avoid the generation of blind spots and ensure the accuracy of detection.

[0085] The testing equipment 1 is equipped with a third connecting frame 755, on which a positioning frame 756 and an adjusting frame 757 are slidably mounted. A fourth camera 758 is slidably connected to the adjusting frame 757. The positioning frame 756 is equipped with a clamping unit, which clamps the battery and positions it, as well as the battery's edge. This allows the third camera 753 to effectively photograph and inspect the battery's tail and tabs. The fourth camera 758 moves on the adjusting frame 757 to ensure that the battery is under appropriate illumination, thus ensuring accurate and clear testing.

[0086] The bottom of the cell handling unit 73 is provided with a bottom surface detection unit 76. The bottom surface detection unit 76 includes a bottom surface detection connecting frame 761 fixedly installed on the detection equipment 1. A fifth camera 762 is installed on the bottom surface detection connecting frame 761. An upper connecting frame 763 is provided directly above the fifth camera 762. The upper connecting frame 763 is installed on the detection equipment 1. Multiple bottom surface detection components 764 are installed on the upper connecting frame 763 through a transmission mechanism.

[0087] By adjusting the bottom surface detection component 764 to a suitable angle, the battery can be effectively inspected over a large area, avoiding blind spots and ensuring the effectiveness of the inspection. When the battery is transferred to the top of the upper connecting frame 763 by the cell transport unit 73, the battery is photographed by the bottom surface detection connecting frame 761. Multiple bottom surface detection components 764 are used to inspect the battery over a large area. The side detection unit 71, the large surface detection unit 72, the tab flipping unit 74, the tab tail detection unit 75, and the bottom surface detection unit 76 are used to comprehensively inspect the front, sides, tail, and tabs of the battery, ensuring the accuracy and precision of the inspection.

[0088] Working principle: The battery is transferred through the transmission mechanism 2, so that the battery enters the detection device 1 for shooting and detection. The sliding cover 302 is opened and the battery is transported to the pull transmission frame 303. The battery is moved by the transmission mechanism. At the same time, the clamping mechanism on the sliding cover 302 ensures the stability of the battery movement and positions the battery.

[0089] The transverse track 403 is activated, causing the second guide rail 404 to slide along the first guide rail 402. As the second guide rail 404 moves, the clamping connecting frame 407 and the clamping hand 408 move accordingly until the clamping hand 408 is directly above the battery in the detection pull belt assembly 3. The sliding frame 406 moves, causing the clamping connecting frame 407 and the clamping hand 408 to move downward. At this time, the two clamping hands 408 are at both ends of the battery and move towards each other to clamp the battery. Then, the transverse track 403 is activated, causing the second guide rail 404 to slide on the first guide rail 402. With the help of the sensors set in the detection device 1, the battery is clamped and moved to the cell transport unit 73 for transfer.

[0090] When the battery is clamped above the placement rack 735 by the clamping hand 408, the battery is lowered so that it first contacts and is squeezed by the two transport positioning blocks 737 to position the battery. Under the action of gravity, the battery contacts the two contact frames 736. When the battery needs to be transferred, the placement rack 735 pushes the battery upward to separate it from the contact frames 736. Then, the transport drive 733 drives the placement rack 735 to move so that the battery is between another set of transport positioning blocks 737 and contact frames 736. When the placement rack 735 moves downward to contact the contact frames 736, multiple batteries perform the above movements at the same time to complete the transfer of the batteries.

[0091] When the battery is transferred through the cell transport unit 73, the battery passes through the first side detection unit 71. The side detection unit 71 takes pictures of the battery and the side detection component 714 takes pictures of the side of the battery. At the same time, the first camera 716 takes pictures of the side of the battery. The position of the first guide rod 712 on the side detection mounting base 713 is adjusted to detect the side of batteries of different sizes.

[0092] When the battery is directly below the sliding base 726, the image is taken through the sliding base 726. At the same time, multiple large-area detection components 723 are used to take pictures and detect the battery tabs and front. By rotating the angle of the large-area detection components 723, it is convenient to take pictures and detect different battery tabs of different sizes to effectively ensure the detection effect.

[0093] Under the action of the flipping moving frame 744, the flipping component 743 is moved. The battery is fixed in the flipping component 743 by the clamping mechanism. Then, the flipping component 743 is rotated by the pushing cylinder 742 to flip the battery, thereby flipping the tabs on the battery. Then, the battery is transported to the cell transport unit 73 for transfer by the flipping moving frame 744.

[0094] The positions of the electrode tail detection component 754 and the third camera 753 are adjusted on the first connecting frame 751 and the second connecting frame 752 to facilitate the shooting and detection of batteries of different sizes. A rotating mechanism is provided between the third camera 753 and the second connecting frame 752. The angle of the electrode tail detection component 754 is adjusted by the rotating mechanism to avoid the generation of blind spots and ensure the accuracy of detection.

[0095] The battery is clamped by the clamping unit on the positioning frame 756, which simultaneously positions the battery and the battery edge. This allows the third camera 753 to effectively photograph and inspect the battery tail and tabs. The fourth camera 758 moves on the adjustment frame 757 to ensure that the battery is under appropriate lighting, thus ensuring accurate and clear inspection.

[0096] By adjusting the bottom surface detection component 764 to a suitable angle, the battery can be effectively inspected on a large scale, avoiding blind spots and ensuring the effectiveness of the inspection. When the battery is transported to the top of the upper connecting frame 763 by the cell transport unit 73, the battery is photographed by the bottom surface detection connecting frame 761, and the battery is inspected on a large scale by multiple bottom surface detection components 764. The inspected battery is then transported by the transmission mechanism 2.
