The battery formation/capacity grading system enables the battery to move among different devices without using a tray when the battery is formed/graded, so that the aim of reducing the production cost is fulfilled, and the phenomenon that the battery is deviated in position, toppled and the like to influence the formation/capacity grading effect is avoided. According to the invention, after a tray is cancelled, the pull belt is adopted to replace a roller for conveying, the battery is directly conveyed through the pull belt, a station for disassembling and assembling the tray by a robot is omitted, and auxiliary equipment can directly work on a pull belt line, so that the equipment cost of a production line is greatly reduced, and the field space is saved.

According to the battery formation/capacity grading system, when the battery clamping manipulator clamps/releases the battery, the whole manipulator does not need to move up and down, the upper clamping jaw part only moves for small displacement in the up-and-down direction, the requirement on the movement space in the height direction is low, the internal space of the existing formation/capacity grading cabinet can be met, and therefore the size of the existing formation/capacity grading cabinet does not need to be changed. If the transfer manipulator shown in fig. 17 is used instead of the battery gripping manipulator, the required up-and-down movement space is larger because the transfer manipulator needs to move up and down as a whole, which is obviously not satisfied by the existing chemical/volume conversion cabinet.

The parts not involved in the battery formation/capacity separation system of the present invention (for example, the control part for controlling the coordinated operation of the battery transport device, the stacker, and the like) are the same as or can be realized by the prior art.

The above-mentioned embodiments are only used to further illustrate the battery formation/capacity grading system of the present invention, but the present invention is not limited to the embodiments, and any simple modification, equivalent change and modification made to the above-mentioned embodiments according to the technical spirit of the present invention fall within the protection scope of the technical solution of the present invention.
