[0002] Lithium-ion batteries are rechargeable batteries commonly used in mobile phones, laptops, electric vehicles, energy storage systems, and other fields. Equipment used for detecting surface defects on lithium-ion battery electrodes is a key quality control tool in the lithium-ion battery manufacturing process. It is mainly used to detect surface defects generated during electrode coating, rolling, slitting, and other processes to ensure the safety and performance of the battery.

[0003] In the existing technology, since the positive and negative electrodes of a lithium battery are located at the two ends of the lithium battery respectively, the existing lithium battery electrode surface defect detection equipment is not convenient to rotate to the lithium battery to detect the other electrode after completing the detection of one end of the electrode, which reduces the detection efficiency. At the same time, when detecting the surface electrodes of a lithium battery, multiple lithium batteries are usually placed mixed together on a conveyor belt and moved through the detection equipment for detection. The existing lithium battery electrode surface defect detection equipment is not convenient to feed the lithium batteries into the detection one by one, which reduces the accuracy of the detection. Utility Model Content

[0004] To overcome the shortcomings of existing technologies and solve the problem that it is convenient to feed lithium batteries one by one into the testing process, but inconvenient to rotate the lithium battery to test the other end of the electrode after completing the testing of one end of the electrode, this utility model proposes a device for testing surface defects of lithium battery electrodes.

[0005] The technical solution adopted by this utility model to solve its technical problem is: the device for surface defects of lithium battery electrode sheet according to this utility model includes a base plate, a vertical plate is fixedly connected to the top edge of the base plate, a rotating component is connected through the inner surface of the vertical plate, and a moving component is rotatably connected to the middle of one side of the rotating component. The rotating assembly includes a transmission rod A that is connected through to the surface of the vertical plate. One end of the transmission rod A is splined to the output end of the servo motor A. The other end of the transmission rod A is fixedly connected to a rotating disk A. A connecting rod is fixedly connected to one edge of the rotating disk A. One end of the connecting rod is fixedly connected to a rotating disk B. The vertical plate is rotatably connected to one side of the rotating disk A. The moving component includes a threaded rod rotatably connected to the center of one side of the A rotating disk. A threaded cylinder is threadedly connected to the surface of the threaded rod. A fixing clamp is fixedly connected to one side of the threaded cylinder in a linear array. A B transmission rod is fixedly connected to one end of the threaded rod. One end of the B transmission rod is splinedly connected to the output end of the B servo motor.

[0006] Preferably, the surface of the A servo motor is fixedly connected to the A motor box, and a vertical plate is fixedly connected to one side of the A motor box.

[0011] The advantages of this utility model are: 1. The rotating component structure of this utility model fixes the lithium battery to be tested on the moving component. After the moving component drives the lithium battery through the testing equipment body to test one end of the electrode, the A servo motor is powered on, which drives the A rotating disk to rotate through the A transmission rod, and drives the B rotating disk to rotate through the connecting rod. This causes the structure including the moving component, which is fixedly connected to the rotating disk, to rotate half a turn, so that the other end of the lithium battery faces upward. The other end of the electrode is then tested by the moving component moving in the opposite direction, which improves the testing efficiency. 2. This utility model, through the structural design of the moving component, fixes the lithium battery in a vertical position with a fixing clamp when inspecting the surface defects of lithium battery electrodes. The B servo motor is powered on, and the B transmission rod drives the threaded rod to rotate. The threaded rod pushes the threaded cylinder to move linearly along the threaded rod, so that the lithium batteries pass through the inspection equipment body one by one for inspection, thereby improving the accuracy of the inspection.

During operation, the rotating component 3 fixes the lithium battery to be tested onto the moving component 4. The moving component 4 drives the lithium battery through the testing equipment body 9 to test one end of the electrode. Then, the A servo motor 302 is energized, which drives the A rotating disk 303 to rotate via the A transmission rod 301. The B rotating disk 305 is then rotated via the connecting rod 304, which in turn drives the structure including the moving component 4, which is fixedly connected to the rotating disk, to rotate half a turn, so that the other end of the lithium battery faces upward. The moving component 4 then moves in the opposite direction to test the other end of the electrode, improving the testing efficiency. Through the structural design of the moving component 4, when testing for surface defects of the lithium battery electrode, the lithium battery is fixed in a vertical position by the fixing clamp 403. The B servo motor 405 is energized, and the B transmission rod 404 drives the threaded rod 401 to rotate.
