By producing battery cells separately and then assembling them, the voltage and capacity of the battery products can be improved, as well as the production efficiency can be increased.

[0003] To ensure the quality of the assembled battery, after the cell production is completed, the cells need to undergo processes such as cleaning, testing, sorting, loading, and assembly. Therefore, individual cells need to be transported between different workstations to perform different processes.

[0004] During transportation, the internal materials of the battery cell may be displaced due to vibration, such as the tabs becoming misaligned, which affects the detection effect of the individual battery cell and the yield of battery products. Utility Model Content

For example, they can refer to a fixed connection, a replaceable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in the embodiments of this application according to the specific circumstances.

[0046] Please see Figure 1 and Figure 2 This application provides a conveying device with battery cell positioning, comprising: a conveyor line 100 and a plurality of positioning components 200. The conveyor line 100 is used to convey battery cells. In application, the conveyor line 100 can be, for example, a belt.

[0047] The positioning assembly 200 is used to align individual battery cells on the conveyor line. The positioning assembly 200 includes a placement plate 210 and a pusher 220; the placement plate 210 is used to abut one side of the individual battery cell; the pusher 220 is used to push the other side of the individual battery cell on the placement plate 210.

[0048] In this embodiment, the alignment operation refers to the positioning component 200 providing pushing and supporting forces to the battery cell, so that the materials in the battery cell (such as the positive electrode sheet, separator, and negative electrode sheet) can be reset to the aligned state due to the pushing force after displacement caused by vibration, thereby achieving positioning of the battery cell. Specifically, the placement plate 210 can be used to abut against one side of the battery cell to provide supporting force to one side of the battery cell; the pushing member 220 can push the other side of the battery cell to provide pushing force to the other side of the battery cell, thereby pushing the materials in the battery cell to reset to the aligned state, thereby reducing the impact of vibration on the alignment degree of the materials during the conveying process.

[0049] In application, the placement plate 210 and the pusher 220 can be configured such that one is fixed to the conveyor line 100 and the other is movable.

[0050] In one implementation, for example, the placement plate 210 is fixed to the conveyor line 100. During the conveying of individual battery cells, the individual cells are conveyed to abut the placement plate 210. Afterward, the conveyor line 100 stops conveying, and the pusher 220 moves into the conveyor line 100, pushing the other side of the individual battery cell for alignment. After alignment, the individual battery cell is removed for the next process. The movable nature of the pusher 220 allows it to avoid individual battery cells during the conveying process.

[0051] In summary, in this embodiment, the alignment operation of the battery cell before the process is configured to be carried out on the conveyor line 100, which can achieve rapid positioning and rapid alignment, thereby facilitating the rapid docking of the battery cell with the next process and improving work efficiency.

[0052] In one embodiment, a cutout area 110 is provided on the conveyor line 100; the placement plate 210 and the pusher 220 are vertically and vertically disposed within the cutout area 110. For example, the cutout area 110 may be disposed in the middle of the conveyor line 100.

[0053] Before alignment is required, the conveyor line 100 transports individual battery cells above the positioning assembly 200. Then, the placement plate 210 and the pusher 220 rise until the individual battery cell is positioned between them. After alignment by the positioning assembly 200, the individual battery cell can be removed by a transfer mechanism (such as a robot) to the next processing station, or the placement plate 210 and the pusher 220 can be lowered to avoid the individual battery cell before continuing to transport it.

[0054] For a more specific embodiment, please refer to Figures 1 to 3The positioning component 200 includes: a support plate 230 and a lifting drive component 240; a lifting plate 231 is provided on the support plate 230; a placement plate 210 and a pushing component 220 are provided on the plate 231; the lifting drive component 240 is provided on the support plate 230 and its output end is connected to the plate 231.

[0055] The lifting drive component 240 can be a linear drive mechanism such as a cylinder. The plate 231 can be a T-shaped plate with a flat top to accommodate the plate 210 and the pusher 220. The support plate 230 can be provided with a slide rail for the plate 231 to slide.

[0056] In one embodiment, the pushing member 220 includes a pushing drive member 221 and a push plate 222. The output end of the pushing drive member 221 is connected to the push plate 222, which drives the push plate 222 to move horizontally to push the other side of the battery cell, so that the battery cell moves on the placement plate 210 to achieve positioning of the battery cell. Specifically, under the push of the push plate 222, the battery cell can move on the placement plate 210, and eventually move until one side of the battery cell abuts against the placement plate 210. During the movement, the displaced material on the battery cell is pushed back to its original position, thereby achieving positioning and alignment of the battery cell, that is, completing the alignment operation.

[0057] The push drive component 221 can be, for example, a linear drive mechanism such as a cylinder.

[0058] Optionally, the pusher 220 includes: a reference plate 223 and an elastic member 224; the reference plate 223 is fixedly connected to the pusher drive member 221; the two ends of the elastic member 224 are respectively connected to the pusher plate 222 and the reference plate 223.

[0059] The elastic element 224, in conjunction with the fixed reference plate 223, can provide elastic force to the push plate 222, thereby reducing the impact of the push plate 222 on the individual cells and buffering the thrust provided by the push plate 222.

[0060] In application, the push drive 221 and the reference plate 223 can be fixed on the flat plate 231.

[0061] In one embodiment, the placement plate 210 includes a main board 212 and a raised edge 211; the main board 212 is used to receive individual battery cells; the raised edge 211 is disposed on the main board 212 and is used to abut against one side of the individual battery cells.

[0062] In application, the conveyor line 100 can be equipped with several process stations; each process station corresponds to a number of positioning components 200.

[0063] The process stations can perform cleaning, testing, and other processes on individual battery cells. Furthermore, the process stations are set up according to the sequence of processes that need to be performed on individual battery cells during battery production. The mainboard 212 can lift the individual battery cells to facilitate the transfer operation of the process station's transport mechanism.

[0064] In one embodiment, a plurality of positioning structures 120 are provided on the conveyor line 100; the positioning structures 120 are used for placing individual power supply cores.

[0065] The positioning structure 120 is used to assist in fixing the battery cell, so as to position the battery cell during the transportation process and reduce the displacement of materials inside the battery cell.

[0066] In one embodiment, the positioning structure 120 includes four positioning posts 121; the four positioning posts 121 are symmetrically arranged on both sides of the hollow area 110; both sides of the battery cell abut against the positioning posts 121.

[0067] The distance between the two positioning posts 121 located on the same side of the hollow area 110 can be configured to be slightly larger than the width of the battery cell to facilitate the insertion of the battery cell.

[0068] In one embodiment, a positioning sensor 130 is provided on the conveyor line 100; when the positioning component 200 performs an alignment operation, the positioning sensor 130 is aligned with the center line of the positioning structure 120.

[0069] Similarly, the position of the positioning sensor 130 corresponds one-to-one with the workstations of the aforementioned processes. The position of the push plate 222 after the alignment operation is completed is called the alignment position. When the center line of the positioning structure 120 is aligned with the center line of the positioning sensor 130, the center line between the push plate 222 and the protruding edge 211 at the alignment position is also aligned with the positioning sensor 130.

[0070] In this embodiment, the positioning sensor 130 facilitates the central control processor to control the start and stop of the conveyor line 100, ensuring that individual battery cells are conveyed to the processing station. Furthermore, the conveyor device with individual battery cell positioning provided in this embodiment integrates the alignment operation of the individual battery cells and the alignment operation before the next process on the conveyor line 100, reducing vibration during conveying and effectively improving work efficiency.

[0071] The above are merely preferred embodiments of this application and are not intended to limit the present invention. Although the present application has been described in detail with reference to examples, those skilled in the art can still modify the technical solutions described in the foregoing examples or make equivalent substitutions for some of the technical features. However, any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
