[0072] It should be noted that like reference numerals and letters refer to similar items in the following figures, and therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0073] Reference Figure 1 As shown, according to an embodiment of the present application, a lifting system 1 is provided, the lifting system 1 comprising a first line body 111, a second line body 112, a third line body 121 and a fourth line body 122 arranged in sequence from top to bottom; the first line body 111, the second line body 112, the third line body 121 and the fourth line body 122 all transport the carrier along a first direction;

[0074] The first layer changing machine 13, the second layer changing machine 14 and the lifting machine 15 are further included. The first layer changing machine 13 is connected to the first ends of the first line body 111 and the second line body 112. The first layer changing machine 13 is used to lift and lower the carrier along the second direction so that the carrier can be transferred between the first line body 111 and the second line body 112.

[0075] The second layer changing machine 14 is connected to the first ends of the third line body 121 and the fourth line body 122, and the second layer changing machine 14 is used to lift and lower the carrier along the second direction so that the carrier can be transferred between the third line body 121 and the fourth line body 122;

[0076] Along the first direction, the first line body 111, the second line body 112, the third line body 121 and the fourth line body 122 are arranged on the same side of the elevator 15;

[0079] The lifting system provided in the embodiment of the present application can be used to transport battery cells during the production and manufacturing process of batteries. The battery cells are placed on a carrier, and the battery cells and the carrier are transported together in the lifting system.

[0080] Specifically, the carrier can flow along the first line 111, the second line 112, the third line 121 and the fourth line 122 in the first direction; that is, the first line 111, the second line 112, the third line 121 and the fourth line 122 transport the carrier along the same horizontal direction (defined as the first direction). In addition, the carrier can be transferred in the vertical direction (defined as the second direction) through the first layer changer 13, the second layer changer 14 and the elevator 15; for example, through the descending action of the first layer changer 13, the carrier can be transferred from the first line 111 to the second line 112; through the descending action of the second layer changer 14, the carrier can be transferred from the third line 121 to the fourth line 122.

[0144] In this specific example, two lifting systems 1 and two circulation layers are provided. Under normal circumstances, the two lifting systems 1 and the two circulation layers are independent production systems, each working independently, which can expand production capacity and improve production efficiency.

[0148] Reference Figure 1 , Figure 2a As shown, the first direction is Figure 1 , Figure 2a The a direction shown in the figure, the second direction is Figure 1 , Figure 2a The b direction is shown in the figure, and the third direction is Figure 1 , Figure 2a The c direction shown in .

[0149] A complete working cycle of the circulating production line is as follows:

[0150] The following is an explanation using a carrier as a pallet as an example; the pallet has two states, the first state is an empty pallet without battery cells, and the second state is a loaded pallet with battery cells; Figure 1 The hollow arrows A1 in FIG2 represent the flow direction of the empty pallets, and the solid arrows A2 represent the flow direction of the loaded pallets.

[0151] On the fifth conveyor line 221 of the second sub-layer 22 in the first circulation layer, the empty pallet after the robot takes the battery cells is transferred to the first conveyor line 241 of the fourth sub-layer 24 for transportation through the descending action of the reciprocating elevator 25, and the empty pallet flows to the second conveyor line 242 through the reversing action of the first reversing machine 243; and then transferred to the fourth conveyor line 232 of the third sub-layer 23 through the lifting action of the third layer changing machine 234, thereby participating in the circulation of the third sub-layer 23.

[0152] At the same time, in the lifting system 1, the loading pallet on the third line body 121 is converted into an empty pallet after the material picking operation of the robot, and then the empty pallet is transferred to the fourth line body 122 through the descending action of the second layer changing machine 14, and then transferred from the fourth line body 122 to the first line body 111 through the lifting action of the first lifting part 151 to participate in the transportation of the first circulation layer in the circulation layer.

[0153] As described above, the empty pallet is transferred to the fourth conveyor line 232 of the third sub-layer 23 through the lifting action of the third layer changing machine 234. The empty pallet is converted into a loaded pallet through the unloading operation of the robot on the fourth conveyor line 232. The loaded pallet flows to the third conveyor line 231 through the reversing action of the second reversing machine 233, and then is transferred to the eighth conveyor line 211 of the first sub-layer 21 through the lifting action of the reciprocating elevator 25 to wait for the robot to perform pairing operations.

[0154] In the first sub-layer 21, the robot performs a pairing and material picking operation on the loaded pallet transferred from the third conveyor line 231 to the eighth conveyor line 211, thereby converting the loaded pallet into an empty pallet. The empty pallet is transferred to the fifth conveyor line 221 of the second sub-layer 22 through the descending action of the fourth layer changing machine 210, and then transferred to the first conveyor line 241 of the fourth sub-layer 24 through the descending action of the reciprocating elevator 25, thereby participating in the conveying cycle of the fourth sub-layer 24 again.

[0155] Continuing from the above, the empty pallet is transferred from the fourth line body 122 to the first line body 111 through the lifting action of the first lifting part 151, and then is transported to the ninth conveyor line 212 through the tenth conveyor line 213. The empty pallet is transformed into a loading pallet through the matching unloading operation of the robot on the ninth conveyor line 212. The loading pallet is transferred to the sixth conveyor line 222 through the descending action of the fifth layer changing machine 220, and then the loading pallet reaches the second line body 112 through the conveying action of the seventh conveyor line 223, and then is transferred from the second line body 112 to the third line body 121 through the descending action of the second lifting part 152, and then at the third line body 121, the loading pallet is transformed into an empty pallet through the picking operation of the robot, and finally the empty pallet is transferred to the fourth line body 122 through the descending action of the second layer changing machine 14 to participate in the transportation of the lifting system 1.
