[0045] The conveyor line 2 includes: a plurality of cooling conveyor chains 21, a battery feeding conveyor chain 22, a battery discharging conveyor chain 23 and a plurality of steering components 24;

[0046] A plurality of conveyor chains are installed in parallel with each other on the frame 11 and located in the cooling chamber, and the conveying directions of adjacent cooling conveyor chains 21 are opposite. The cooling conveyor chains 21 are used to convey the trays 3 loaded with batteries 4;

[0047] The battery feeding conveyor chain 22 passes through the battery 4 feeding port and enters the cooling chamber. The battery feeding conveyor chain 22 is arranged on one side of the plurality of cooling conveyor chains 21. The battery feeding conveyor chain 22 is used to convey the support cup 3.

[0048] The battery discharge conveyor chain 23 passes through the discharge port of the battery 4 and exits the cooling chamber. The battery discharge conveyor chain 23 is arranged on the other side of the plurality of cooling conveyor chains 21. The battery discharge conveyor chain 23 is used to convey the support cup 3.

[0050] The cooling assembly 13 can reduce the temperature of the cooling cavity. The battery feeding conveyor chain 22 passes through the battery 4 feeding port to feed the cup 3 loaded with the battery 4 into the cooling cavity, and can cool the battery 4 during the process of transferring from the first end to the second end of the cooling furnace body 1. After the battery feeding conveyor chain 22 completes the transfer of the cup 3 loaded with the battery 4, the battery 4 is turned and transposed to the adjacent cooling conveyor chain 21 by the steering assembly 24, and then the battery 4 is transferred from the second end of the cooling furnace body 1 to the first end by the cooling conveyor chain 21 for cooling. After that, the steering assembly 24 turns and transposes the battery 4 from the current cooling conveyor chain 21 to the next cooling conveyor chain 21, and the next cooling conveyor chain 21 transfers the battery 4 from the first end of the cooling furnace body 1 During the transfer to the second end, the battery 4 is cooled.

Finally, the battery 4 of the last cooling conveyor chain 21 is turned and replaced to the battery discharge conveyor chain 23 by the steering assembly 24. The battery discharge conveyor chain 23 passes through the battery 4 discharge port to withdraw the battery 4 from the cooling chamber to complete the cooling of the battery 4. During the cooling process, the battery 4 is cooled individually and will not be affected by the tray. The cooling effect is good. At the same time, a single battery 4 can be transported by the conveyor line 2 through the cooling furnace body 1 for cooling and unloading. In addition, the conveyor line 2 has several cooling conveyor chains 21, so multiple batteries 4 can be cooled at the same time, which improves the cooling efficiency. Compared with the existing cooling furnace body 1 that requires the tray to be taken and placed, the process of putting the battery 4 into the tray and taking it out from the tray is reduced, which can enable the battery 4 to enter the downstream processing program earlier, and improve the manufacturing efficiency of the battery 4. At the same time, there is no tray body to block the cold air, so that each battery 4 is exposed to the surrounding cold air environment, and the battery cools down faster, which improves the cooling efficiency.

[0061] When a predetermined number of cups 3 enter the battery feed conveyor chain 22 and pass through the longitudinal distance adjustment component 2212, the limit cylinder 221211 on the side away from the incoming material drives the limit member 221212 to block the cup 3, and the limit cylinder 221211 on the side close to the incoming material drives the limit member 221212 to block the incoming cup 3, and then the adjustment cylinders 221221 on both sides drive the adjustment racks 221222 to close, so that the cups 3 are fixed by adjusting the pitch of the racks 221222. , so that the manipulator can accurately place the battery 4 into the tray 3.
