[0026] The specific implementation method is as follows: by setting up a guide classification component 4, the cooperation between the conveying roller 9 and the driving member 3 realizes the automatic transportation and precise positioning of the power battery. The guiding effect of the guide wheel 405 and the guide rod 404 makes the battery accurately centered, which significantly improves the positioning accuracy and detection efficiency.

[0027] Working principle: When in use, the staff drives the electric push rod 407, and the electric push rod 407 drives the guide rod 404 to move, so that the guide rod 404 and the guide wheel 405 adapt to the width of the power battery to be tested. The staff places the power battery to be tested on the conveying roller 9, and the driving member 3 drives the conveying roller 9 to rotate, so that the conveying roller 9 drives the power battery to move to one side. The power battery is guided by the guide rod 404 and the guide wheel 405 to be located in the center position of the conveying roller 9. The guide wheel 405 guides the side of the power battery and moves the power battery to the fixed position. Directly below the fixed frame 5, at this time, the driving member 3 stops driving the conveying roller 9, so that the power battery stagnates directly below the fixed frame 5, and the detection and impurity removal component 6 detects the power battery. If the power battery is detected to be qualified, the driving device 401 drives the guide slot seat 402 to swing to the right, so that the power battery passes the guide slot seat 402 and the guide wheel 403 to move to the left.
