[0022] The lithium batteries to be tested are transported in an orderly manner to the location of the two power-connecting copper plates 8 by using the conveying correction component, so that the lithium batteries to be tested pass under the two power-connecting copper plates 8 in turn. The two power-connecting copper plates 8 pushed by the elastic force of the first spring 6 are in close contact with the positive and negative poles of the lithium battery respectively, so that the lithium battery supplies power to the indicator light 11 through the power-connecting copper plates 8, the power-connecting copper columns 10, and the wires 12 in turn. It is observed whether the indicator light 11 is lit to realize the detection of the power-on status of the lithium battery, so that the power-on detection of the lithium battery does not require manual alignment and is more intuitive.

[0023] Among them, a plurality of fixing rods are fixed through the support base 1, and both ends of the fixing rods are rotatably connected to two rollers 14 through bearings. With the help of the multiple rollers 14, the device is more convenient to transfer positions.

[0024] Among them, the conveying correction component includes a U-shaped seat 18, which is fixedly mounted on the support seat 1, and two transmission rollers 19 are rotatably connected between the opposite inner walls of the U-shaped seat 18 through bearings. A conveyor belt 20 is provided on the two transmission rollers 19, and a plurality of groups of plywood 21 are provided on the conveyor belt 20, and each group of plywood 21 has two plywoods. A driving motor 22 is provided on the front side of the U-shaped seat 18, one of the transmission rollers 19 is driven by the driving motor 22, and a supporting plate 23 is fixed between the opposite inner walls of the U-shaped seat 18. The supporting plate 23 is located on the inner side of the conveyor belt 20, and a group of carrier blocks 24 are fixed to the opposite inner walls of the U-shaped seat 18.

[0025] The driving motor 22 is used to drive the conveyor belt 20 to transport the lithium batteries. The lithium batteries to be tested are separated one by one by means of multiple groups of clamps 21 set on the conveyor belt 20. The lithium batteries being transported can be gathered to the middle of the conveyor belt 20 under the guidance of the two guide plates 25 to complete the adjustment of their own positions.

The two guide plates 25 can guide the lithium batteries to be tested to gather in the middle of the conveyor belt 20, so that the lithium batteries to be tested are guided to the predetermined position;

[0030] When the lithium battery to be tested is moved under the two power-connecting copper plates 8, because its position has been precisely guided, the two power-connecting copper plates 8 are in contact with the positive and negative poles of the lithium battery respectively. The current is conducted to the indicator light 11 along the power-connecting copper plates 8, the power-connecting copper columns 10, and the wires 12. If the indicator light 11 lights up normally, it is determined that the lithium battery is powered normally. If the indicator light 11 does not light up, the worker will remove it and manually perform a secondary test. The qualified lithium battery will continue to move with the conveyor belt 20 and can slide onto the unloading chute 16. Multiple second springs 15 and multiple third springs 17 can provide buffering protection for the lithium battery when it enters the unloading chute 16. The lithium battery that slides down the unloading chute 16 is transported by workers.
