[0027] The rotating assembly 4 comprises a first rotating rod 401 rotatably installed on the inner front wall of the bottom plate 1, a first motor 402 fixedly installed on the front surface of the bottom plate 1, a main helical gear 403 fixedly installed on the surface of the first rotating rod 401, a slave helical gear 404 engaged with the right side of the main helical gear 403, a second rotating rod 405 fixedly installed in the middle of the slave helical gear 404, a worm 406 fixedly installed on the right side of the second rotating rod 405, a worm wheel 407 engaged with the rear side of the worm 406, and a third rotating rod 408 fixedly installed in the middle of the worm wheel 407.

The bidirectional screw rod 301 extends to one side outside the test platform 2 and is provided with a handle. When testing, the battery is placed on the top of the test platform 2, and then the bidirectional screw rod 301 is rotated through the handle. The bidirectional screw rod 301 drives the two clamping blocks 303 to move relative to each other through the screw block 302, so as to clamp the battery.

[0029] As shown in Figure 4 , the detection box 6 is arranged, and the knocking assembly 7 is arranged in the detection box 6. The knocking assembly 7 comprises a fourth rotating rod 701, a sector gear 702, a double-sided rack 703, a second motor 704, a moving plate 705 and a knocking rod 706.

[0032] In implementation, the following steps are performed:

[0033] 1) First, the mechanical stability of the battery is detected through the knocking assembly 7, the infrared emitter 11 and the infrared receiver 12;

[0034] 2) Then, after the detection is completed, the first motor 402 is started, and the first motor 402 drives the first rotating rod 401 to rotate;

[0035] 3) Then, the first rotating rod 401 drives the second rotating rod 405 to rotate through the cooperation of the main bevel gear 403 and the driven bevel gear 404, the second rotating rod 405 drives the worm 406 to rotate, and the worm 406 drives the third rotating rod 408 to rotate through the meshing with the worm wheel 407;

[0036] 4) Finally, the third rotating rod 408 drives the mounting column 5 to rotate, so that the lamp box 8 is rotated above the test platform 2, and the performance detection under the actual illumination conditions is performed.
