[0002] In the structure of a lithium battery, the separator is one of the key inner components. The performance of the separator determines the interface structure, internal resistance, etc. of the battery, directly affecting the characteristics such as the capacity, cycle, and safety performance of the battery. A separator with excellent performance plays an important role in improving the comprehensive performance of the battery. The main function of the separator is to separate the positive and negative electrodes of the battery to prevent the two electrodes from contacting and short - circuiting. In addition, it also has the function of allowing electrolyte ions to pass through.

[0003] At present, the existing lithium battery separator detectors on the market have the following technical problems: (1) The position of the line - array camera is fixed. When there is a certain small - angle deviation in the transmission of the lithium battery separator, the existing line - array camera cannot make corresponding small - angle rotation adjustments, affecting the normal shooting of images and thus the detection accuracy; (2) Its light source is directly facing the surface of the lithium battery separator, which will cause serious reflection phenomena, affecting the image shooting quality of the line - array camera and thus the detection accuracy.

[0024] The utility model, by setting a sliding base block 6 and a toggle rod group 5, can make the sliding base block 6 move closer or farther away synchronously under the drive of the bidirectional lead screw 7, and then drive the connecting plate 2 and the lamp body 3 thereon to rotate through the toggle rod group 5, adjust the illumination angle of the lamp body 3, and effectively avoid the reflection phenomenon caused by the illumination angle of the light source, which affects the quality of the subsequent image shooting of the camera component 11; through the second driving motor 10, the shooting angle of the camera component 11 can be independently adjusted, effectively cooperating with the adjustment of the illumination angle of the lamp body 3, to achieve high-precision shooting and detection of lithium battery diaphragms.
