[0136] Repeat the above steps to complete stacking.

[0137] The specific pallet disassembling process is as follows:

[0138] When the disk conveyor line 31 conveys the stacked disks b1 formed by stacking N disks b together to between the two disk-unstacking clamps 316-1, the disk-unstacking lifting cylinder 316-51 extends to drive the disk-unstacking lifting plate 316-53 to extend, lifting the stacked disks b1 to a height exceeding the conveyor belt 317-1;

[0139] The disk-unstacking clamp telescopic driving member 316-3 drives the disk-unstacking clamp 316-1 to extend, clamping the (N-1)th disk b (in the height direction, counting from top to bottom, the 1st disk b is at the topmost, and the Nth disk b is at the bottommost);

[0140] The disk-unstacking lifting cylinder 316-51 retracts to drive the Nth disk b to descend to the surface of the conveyor belt 317-1, and continues to retract, and the Nth disk b flows away along with the conveyor belt 317-1;

[0141] Repeat the above steps to complete disk unstacking.

[0142] Specifically, grooves for the stacked-disk clamping member 315-1 and the disk-unstacking clamp 316-1 to extend into can be provided on each of the disks a and b.

[0143] Furthermore, the feeding direction of the loading line 1 is opposite to the feeding direction of the unloading line 6. Further improves the space utilization rate.

[0144] Specifically, the loading line 1 is adjacent to the disk conveyor line 31 and is arranged parallel to the disk conveyor line 31;

[0145] The unloading line 6 is adjacent to the disk conveyor line 31 and is arranged parallel to the disk conveyor line 31;

[0146] The loading robot 2 is adjacent to the disk conveyor line 31 and is arranged at one end of the loading line 1;

[0147] The unloading robot 5 is adjacent to the disk conveyor line 31 and is arranged at one end of the unloading line 6.

[0148] More specifically, the disk conveyor line 31 is arranged side by side with the aging furnace 4.

[0149] Furthermore, a number of chamber doors 42 are provided at both ends of the aging furnace 4, and the number of the chamber doors 42 is twice the number of the aging chambers 41;

[0150] One chamber door 42 is provided at each of the feeding end and the discharging end of the aging chamber 41, and the chamber door 42 is used to close the aging chamber 41.

[0151] Among them, the setting of the chamber door 42 can reduce the heat leakage in the aging chamber 41 and reduce energy waste.

[0152] A chamber door 42 is provided at the feeding end and the discharging end of each aging chamber 41, which is convenient for opening or closing the aging chamber 41 according to production needs, ensuring that the aging environment of the battery cells in each chamber 41 is independent and controllable.

[0153] Referring to Figure 9 , more specifically, a plurality of conveyor lines 43 are provided in the aging furnace 4, and each of the conveyor lines 43 is disposed at the bottom of each aging chamber 41 for driving the tray a / tray b.

[0154] Each of the conveyor lines 43 can rotate synchronously at the same speed, or the conveyor lines 43 in different aging chambers 41 can have different transmission speeds, and the specific situation can be adjusted according to production needs.

[0155] The setting of the conveyor line 43 further improves the automation degree of the aging furnace.

[0156] Further, a plurality of mounting positions for mounting the battery cells are provided on the tray a / tray b / tray c. It can realize the one-time transmission and aging of multiple battery cells, improving the aging efficiency of the battery cells.

[0157] The above is a specific description of the preferred embodiment of the present invention, but the present invention is not limited to the above embodiments. Those skilled in the art can make various equivalent deformations or substitutions without departing from the spirit of the present invention, and these equivalent deformations or substitutions are all included in the scope defined by the claims of this application.
