As the conveying device 11 operates, the second-specification batteries 62 and the third-specification batteries 63 are not fixed, and during the operation of the conveying device 11, the batteries fall into the corresponding secondary sorting device 30 due to the action of gravity, and the batteries 61 of the first specification cannot fall off due to being clamped until the batteries are conveyed to the corresponding primary electricity testing device 50, the operation control part 131 drives the clamping arms 133 to move back, so that the clamping heads 135 release the batteries 61 of the first specification, and the batteries 61 of the first specification fall into the primary electricity testing device 50 for electricity testing sorting.

Similarly, the second-specification battery 62 and the third-specification battery 63 which fall into the second-stage sorting device 30 are clamped by the corresponding matched clamping head 135 of the second-stage sorting device 30, so that the second-specification battery 62 cannot fall off, the third-specification battery 63 is not clamped, in the operation process of the conveying device 11, the third-specification battery 63 falls into the corresponding third-stage electricity testing device due to the action of gravity to be subjected to electricity testing sorting, and the second-specification battery 62 is operated to be released and locked to fall into the second-stage electricity testing device to be subjected to electricity testing sorting.
