DETAILED DESCRIPTION

[0015] The utility model will be further described in connection with the drawings.

[0016] Please combine with reference to Figs. 1-3This utility model discloses a power lithium battery testing device, including a base 1. A rear upright plate 6 is fixedly connected to the middle of one side wall of the base 1. A movable groove 7 is opened in the middle of one side wall of the rear upright plate 6, and a movable block 8 is slidably connected in the movable groove 7. A horizontal plate 9 is provided on one side of the movable block 8. A sliding groove 15 is opened in the middle of the side wall of the horizontal plate 9 away from the movable block 8. A bidirectional screw 16 is rotatably connected in the sliding groove 15. A slider 17 is threadedly sleeved at both ends of the bidirectional screw 16. A clamping plate 10 is detachably connected to one end of the slider 17.

[0017] A second motor 18 is detachably connected to one end of the side wall of the horizontal plate 9. The output end of the second motor 18 extends into the slide groove 15 and is detachably connected to one end of the bidirectional screw 16. A first motor 14 is detachably embedded inside the moving block 8. The output end of the first motor 14 passes through its side wall and is detachably connected to the middle of one side wall of the horizontal plate 9. Diagonal bracing plates 2 are fixedly connected to the top of the base 1 and near both ends. Vertical plates 3 are detachably connected to the side wall of the two diagonal bracing plates 2 facing each other. A pressure-applying telescopic rod 4 is detachably embedded in the side wall of the vertical plate 3 near the top. A pressure plate 5 is set between the two vertical plates 3. The output end of the pressure-applying telescopic rod 4 passes through the vertical plate 3 and is detachably connected to one side wall of the pressure plate 5.

[0018] The technical effect of this solution is as follows: The battery is placed on the placement plate 12, and then the pressure extension rod 4 is activated to drive the pressure plate 5 to clamp the battery. The pressure increases intermittently, and each pressure is held for a period of time to observe the battery's performance and appearance changes under different pressures. After the vertical state test is completed, the clamping plate 10 is controlled to clamp the battery. Then, the battery is flipped by the drive of motor 14 to turn it into a horizontal state. The above test steps are repeated to test the battery's lateral pressure resistance. The two tests can effectively improve the comprehensiveness and accuracy of the pressure resistance test.

[0019] The top side wall of the movable slot 7 is detachably inlaid with a lifting and adjusting telescopic column 13. The output end of the lifting and adjusting telescopic column 13 is detachably connected to the middle of the top side wall of the movable block 8. The middle of the top side wall of the base 1 is detachably connected with a height adjusting telescopic rod 11. The output end of the height adjusting telescopic rod 11 is fixedly connected to a placement plate 12. The top side wall of the placement plate 12 is fixedly connected with an anti-slip pad.

[0020] The technical effect of this solution is as follows: starting the lifting and adjusting telescopic column 13 can control the lifting and lowering of the moving block 8 and the horizontal plate 9, so that the battery can be lifted to leave enough space for the clamping plate 10 to flip. At the same time, the height adjusting telescopic rod 11 can drive the lifting and lowering of the placement plate 12 to place the battery on the placement plate 12. After the pressure plate 5 clamps the battery, the placement plate 12 is lowered to avoid affecting the detection effect.

[0021] Specifically, in use, the battery is first vertically placed on the placing plate 12, then the pressing telescopic rod 4 is started to drive the pressing plate 5 to clamp the battery, after clamping is stable, the placing plate 12 is lowered by the height adjusting telescopic rod 11, then the battery is subjected to compression resistance detection, after the vertical state detection is completed, the placing plate 12 is lifted below the battery by the height adjusting telescopic rod 11, at the same time, the pressing plate 5 is away, then the lifting adjusting telescopic column 13 is started to lower the cross plate 9 from above, after the clamping plate 10 is dropped to the two sides of the battery, the second motor 18 is started, the sliding block 17 and the clamping plate 10 are driven by the rotating bidirectional screw rod 16 to clamp the battery, then the placing plate 12 is lowered by the height adjusting telescopic rod 11, after that, the first motor 14 is started to drive the cross plate 9 to rotate, so as to drive the clamping plate 10 to overturn, after overturning, the pressing telescopic rod 4 is started to drive the pressing plate 5 to clamp the two ends of the battery, at this time, the clamping plate 10 is loosened to clamp the battery, but itself remains stationary, then the battery can be subjected to transverse compression resistance detection, after the detection is completed, the battery is clamped by the clamping plate 10 and placed on the newly raised placing plate 12, then the staff places a new battery on the placing plate 12, and the clamping plate 10 returns to the original position to wait for reactivation.
