[0002] The importance of the lamination cell hot pressing device in the field of new energy power batteries cannot be ignored. This device is mainly used for hot pressing lamination cells and is one of the key devices in the battery manufacturing process. With the continuous expansion of the new energy vehicle market and the continuous development of power battery technology, the requirements for battery performance and quality are getting higher and higher. As an advanced battery manufacturing device, the lamination cell hot pressing device can meet the market demand for high-performance and high-quality batteries and has good market prospects.

[0003] In current life, in order to ensure the safe use of the cell and prevent the cell from being pinched or deformed, during the production process of the laminated cell, it is necessary to hot press the cell into shape; however, the shape of the laminated cell is loose, and the phenomenon of lamination misalignment is likely to occur during the process of cell displacement and feeding; when processing the cell with the existing hot pressing technology, imprints will be generated after processing the cell and hot pressing the laminated battery, and the clamping jaws will pinch the cell. In terms of the hot pressing effect, the phenomenon of unstable quality occurs from time to time, such as imprints, pinching, etc., with low efficiency, high defect rate, and high cost;

[0004] An existing patent (Publication No.: CN218472031U) for a lamination cell hot pressing device includes a material clamping device and a hot pressing device.

[0036] The heating mechanism 6 includes a heating component 61, a jaw telescopic component 62, and an elastic tensioning component 63. The heating component 61 includes an upper heating receiving platform 611, a lower heating receiving platform 612, a guide rail slider 613, an equal-height column 614, a displacement sensing component 615, and a heating and temperature sensing component 616. Both the upper heating receiving platform 611 and the lower heating receiving platform 612 are arranged between the columns 1. The lower heating receiving platform 612 is located below the upper heating receiving platform 611. The number of the upper heating receiving platforms and the lower heating receiving platforms is five groups, and four pressing spaces are formed between every two of them. The guide rail slider 613 is arranged at the connection of the upper heating receiving platform, the lower heating receiving platform, and the column 1.

[0038] Specifically, as Figure 9 shown, the elastic tensioning component 63 includes a convex mounting block 631, an XHS type damping spring shock absorber 632, a lower pressing block 633, and an upper pressing block 634. The convex mounting block 631 is fixedly arranged at the top of the lower heating receiving platform 612, and the number of them is two groups and they are arranged left and right. The XHS type damping spring shock absorber 632 is horizontally installed between the two convex mounting blocks 631.

The number of the upper pressing blocks 634 is two groups and they are respectively fixedly arranged at the top of the lower pressing block 633.

[0039] By setting up the heating mechanism 6, the number of upper heating receiving platforms and lower heating receiving platforms is five groups, and four pressing spaces are formed between every two of them. Four battery cells can be hot-pressed at one time, greatly improving the usage efficiency. For the anti-displacement of the battery cell stack, when the battery cells are placed on the heating press receiving platforms, grippers are set to pick and place the materials alternately to ensure that the battery cells are always clamped by the grippers.

[0040] Specifically, as Figure 7 shown, on one side of the upper heating receiving platform 611 and the lower bearing plate 3, a third cylinder 7 and a first lifting block 8 are both arranged. The first lifting block 8 is fixedly connected to the telescopic rod of the third cylinder 7. The third cylinders 7 on the upper heating receiving platform 611 all extend and retract downward, and the third cylinders 7 on the lower bearing plate 3 all extend and retract upward.

[0041] Specifically, as Figure 6 shown, a fourth cylinder 9 and a second lifting block 10 are arranged on the periphery of the lower heating receiving platform 612. The second lifting blocks 10 are all fixedly connected to the telescopic rods of the fourth cylinders 9.

[0042] Specifically, as Figure 2 shown, a loading docking channel 11 and an unloading docking channel 12 are respectively arranged on both sides of the heating mechanism 6. The loading docking channel 11 and the unloading docking channel 12 are respectively used for the feeding and discharging of the battery cells.

[0043] Specifically, as Figure 2 shown, one end of the loading docking channel 11 is provided with a loading channel 13. The end of the loading channel 13 is provided with a feeding lifting and stratifying device 14. One side of the feeding lifting and stratifying device 14 is provided with a conveying and transferring device 15. The conveying and transferring device 15 is located on one side of the heating mechanism 6.

[0044] Specifically, as Figure 2 shown, an unloading lifting and stratifying device 16 is arranged at the end of the heating mechanism 6. One end of the unloading lifting and stratifying device 16 is provided with a cooling logistics channel 17.

[0045] By setting up the loading docking channel 11, the loading channel 13, the feeding lifting and stratifying device 14, the conveying and transferring device 15, the unloading lifting and stratifying device 16, the cooling logistics channel 17 and the unloading docking channel 12, it is ensured that the battery cells can be smoothly and accurately transported from the outside to the loading area of the hot-pressing equipment, laying a foundation for the subsequent process steps, ensuring the stability and safety of the battery cells during the transmission process, avoiding damage or displacement. The feeding lifting and stratifying device 14 helps to ensure that the battery cells can be evenly stressed during the hot-pressing process, improving the hot-pressing effect. The conveying and transferring device 15 can accurately transfer the battery cells from one station to the next station, ensuring the continuity and high efficiency of the hot-pressing process. The unloading lifting and stratifying device 16 helps to stabilize the performance and structure of the battery cells. The unloading docking channel 12 ensures that the battery cells can be smoothly and accurately transported from the cooling area to the next process or inspection equipment, preparing for the subsequent processing and encapsulation of the battery cells.

[0046] By adopting the above technical solution, the problems existing in most of the existing technologies are solved. That is, this process and the previous process equipment are made into an integrated body, which has a large occupied space, low production capacity, high cost, and is prone to cause misalignment of the battery cell stack body, thus resulting in defective products.

[0047] Working principle: When this application is in use, first, trays are fed into the feeding channel 13 through multiple feeding docking channels 11, and then flow into the feeding lifting and stratifying unit 14. The battery cells in the trays are placed into the hot press through the handling and transfer unit 15. Then, the battery cells after hot pressing are placed into the discharging lifting and stratifying unit 16, and finally flow into the cooling logistics channel 17 and flow out from the discharging docking channel 12. For battery cells of different sizes, only a very small number of parts need to be replaced to meet the production requirements. For the traditional hot press, the original mechanism has only one layer, and the space utilization rate is low. This device has a four-layer mechanism and can hot press four battery cells at a time, greatly improving the use efficiency. For preventing misalignment of the battery cell stack body, whether the tray is in the transportation process of the feeding channel 13, the opening process in the feeding lifting and stratifying unit 14, the process of the handling and transfer unit 15 transporting the battery cells, or the battery cells are placed on the lower heating receiving table, grippers are arranged to alternately pick and place the materials to ensure that the battery cells are always clamped by the grippers. At this time, the battery cells are placed on the lower heating receiving table through the handling and transfer unit 15, and the battery cells are clamped by the gripper telescopic assembly 62. Then, the handling and transfer unit 15 withdraws, and the upper heating receiving table 611 is pressed on the upper surface of the battery cells. The two-side gripper telescopic assemblies 62 retract backward, and then hot pressing is carried out. After the end, the two-side gripper telescopic assemblies 62 extend and clamp, waiting for the handling and transfer unit 15 to pick up the battery cells. The misalignment prevention of the battery cell stack body is realized by clamping with the two-side gripper telescopic assemblies 62.

[0048] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention.
