[0002] With the rapid development of electric vehicles, mobile devices, energy storage systems and other fields, the market demand and application scope of lithium batteries, as key components for energy storage and conversion, are constantly expanding. However, various surface defects may occur in lithium batteries during production and use. These defects not only affect battery performance, but may also cause safety accidents. Therefore, it is crucial to conduct efficient and accurate detection of lithium battery surface defects. Lithium battery surface defects mainly include physical defects (such as dents, pores, cracks, etc.) and chemical defects (such as electrolyte leakage, chemical reactions, etc.). The causes of these defects may involve multiple aspects such as material preparation, production process, and use environment. In order to ensure the safety and reliability of lithium batteries, these defects need to be comprehensively and carefully detected.

[0003] After consulting relevant patent documents, it is found that there are still some problems with the existing lithium battery surface defect detection devices. The optimization solutions currently on the market are mainly: installing a CCD camera on a conveyor belt, and the camera can be raised and manually moved horizontally. However, this method only achieves simple vertical and horizontal displacement, and it is difficult to take pictures of the sides of the lithium battery to check for defects, and manual operation above the conveyor belt is prone to accidents. In response to the above problems, a lithium battery surface defect detection device that can automatically rotate the camera angle and automatically move the camera horizontally is proposed.

[0024] The steering mechanism 16 includes a moving box 1601 , on one side wall of which a steering shaft 1602 is rotatably connected. The top of the steering shaft 1602 located inside the moving box 1601 is fixedly connected to a driven gear 1603 , on the surface of which a driving gear 1604 is meshed.

[0025] A rotating shaft 11 passes through the driving gear 1604 , and a limiting block 1605 is fixedly connected to the inner wall of the moving box 1601 at a position where the rotating shaft 11 passes through the moving box 1601 . The limiting block 1605 contacts the inner wall of the moving box 1601 but is not fixedly connected.

[0026] A rotating block 17 is fixedly connected to the top of the steering shaft 1602 away from the moving box 1601 , and a CCD camera 18 is fixedly connected to the bottom of the rotating block 17 .

[0027] A thread is provided on one end surface of the rotating shaft 11 close to the slide slot 19 , and the thread is meshed with the tooth pattern of the disc gear 12 .

[0028] The slot opening of the slide groove 19 is in an inverted T-shape, and the buckle shape at the bottom of the slider 6 is in a positive T-shape, which is consistent with the size of the slot opening of the slide groove 19.

[0029] The rotating shaft 11 can rotate and slide freely inside the positioning block 10 , and a clamping block is fixedly connected to the bottom end of the moving box 1601 , and the clamping block is fitted with the bottom surface of the supporting plate 9 .

[0030] The working principle of a lithium battery surface defect detection device in the embodiment of the present application is as follows: when the conveyor belt 4 rotates, it will drive the lithium battery placed on its surface to pass under the support plate 9. At this time, for the lithium battery surface that needs to be detected, the motor 14 is first started. At this time, the rotation of the motor 14 will drive the connecting shaft 13 to rotate, thereby driving the disc gear 12 to rotate. At this time, the rotating shaft 11 meshing with the disc gear 12 will rotate, and the rotating shaft 11 will slide along the inside of the positioning block 10. According to the rotation direction of the disc gear 12, when it rotates clockwise, the rotating shaft 11 will move in the direction away from the slide groove 19, and when it rotates counterclockwise, it will move in the opposite direction. During the forward and backward movement of the rotating shaft 11, rotation will also occur. When the rotating shaft 11 moves toward the direction away from the slide slot 19, the rotating shaft 11 itself will rotate clockwise, thereby driving the driving gear 1604 to rotate clockwise, and driving the driven gear 1603 to rotate counterclockwise, so that the CCD camera rotates counterclockwise, and the left side of the lithium battery can be observed; conversely, when the rotating shaft 11 itself rotates counterclockwise, it will drive the driving gear 1604 to rotate counterclockwise, thereby driving the driven gear 1603 to rotate clockwise, and further causing the CCD camera to rotate clockwise, and the right side of the lithium battery can be observed, thereby improving the accuracy of detection and the safety of detection operations.

Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
