[0028] Battery cells are an important component of battery packs. During the manufacturing process of battery cells, multiple battery cells are usually transferred using a transfer frame; however, due to the poor stability of battery cells in the transfer frame, they are prone to bumping and rubbing against each other, which can damage their outer surfaces and affect the appearance quality of the battery cells.

[0029] Furthermore, the slow heat transfer during the baking process prolongs the baking time of the battery cells, and the cooling time of the battery cells after baking is also prolonged due to the slow heat transfer, thus affecting the production efficiency of the battery cells.

[0030] like Figure 1 As shown, in order to solve the above-mentioned technical problems, the embodiments of this application provide a transfer device 100, which relates to the field of battery technology. It is mainly used to transfer battery cells 200 and reduce the risk of battery cells 200 being bumped or damaged by friction during the transfer process.

[0031] It should be noted that the battery cell 200 can be indirectly applied to electrical devices or energy storage devices in the form of a battery pack, or it can be directly applied to electrical devices or energy storage devices without using a battery pack. No specific application scenarios for the battery cell 200 are specified here.

[0032] For example, electrical devices can be vehicles, mobile phones, portable devices, laptops, ships, spacecraft, electric toys, and power tools.

[0033] It should be noted that the battery cell 200 primarily relies on the movement of metal ions between the positive and negative electrode plates to function. The battery cell 200 can be rectangular, cylindrical, flat, or other shapes; classified according to the physical state of the electrolyte, the battery cell 200 can be a liquid battery or a solid-state battery; classified according to the packaging method, the battery cell 200 can be a prismatic battery, a cylindrical battery, a pouch battery, etc.; classified according to the type of metal ions, the battery cell 200 can be a lithium-ion battery, a sodium-ion battery, etc.; no specific limitations are made on the type of battery cell 200 here.

[0034] like Figure 1 As shown, the transfer device 100 provided in this embodiment has a first direction X, a second direction Y and a third direction Z that are perpendicular to each other. The transfer device 100 includes a transfer frame 110 and a plurality of insulating shells 120.

[0035] Combination Figures 2 to 4As shown, the transfer frame 110 has a plurality of first protrusions 111 spaced apart in the first direction X on one side in the second direction Y, and a plurality of first grooves 112 spaced apart in the first direction X on the other side in the second direction Y. The plurality of first protrusions 111 and the plurality of first grooves 112 are arranged opposite to each other in the second direction Y. A plurality of insulating shells 120 are arranged in the first direction X. The plurality of insulating shells 120 are used to accommodate a plurality of battery cells 200. Each insulating shell 120 has a second groove 121 on one side in the second direction Y, and a second protrusion 122 on the other side in the second direction Y. In the third direction Z, the plurality of first protrusions 111 are correspondingly inserted into the second grooves 121 of the plurality of insulating shells 120, and the plurality of second protrusions 122 of the plurality of insulating shells 120 are correspondingly inserted into the plurality of first grooves 112.

[0036] For example, for each battery cell 200, the battery cell 200 can be completely housed within the insulating housing 120; of course, the battery cell 200 can also be partially housed within the insulating housing 120, so that a portion of the battery cell 200 is exposed outside the insulating housing 120, thereby facilitating the handling by operators.

[0037] It should be noted that "the transfer frame 110 is provided with a plurality of first protrusions 111 spaced apart in the first direction X on one side in the second direction Y, and the transfer frame 110 is provided with a plurality of first grooves 112 spaced apart in the first direction X on the other side in the second direction Y" means that the transfer frame 110 is provided with a plurality of first protrusions 111 on one side in the second direction Y, and the plurality of first protrusions 111 on this side are spaced apart in the first direction X, and the transfer frame 110 is provided with a plurality of first grooves 112 on the other side in the second direction Y, and the plurality of first grooves 112 on this side are spaced apart in the first direction X.

[0038] For example, the materials of the insulating housing 120 and / or the transfer frame 110 can be selected from the following categories: 1. Synthetic organic insulating materials: plastics (e.g., polyethylene, polyvinyl chloride, polypropylene, polytetrafluoroethylene, epoxy resin, etc.), synthetic rubbers (e.g., silicone rubber, nitrile rubber, etc.), synthetic fibers (e.g., polyester fiber, nylon, etc.); 2. Natural organic insulating materials: wood, natural rubber, etc.; 3. Inorganic insulating materials: ceramics, glass, mica, quartz, asbestos, etc.; 4. Polymer insulating materials: polycarbonate, polyimide, etc., without specific limitations.

[0039] It is understood that in the transfer device 100 provided in this embodiment, multiple insulating shells 120 are arranged in a row and are used to accommodate multiple battery cells 200 one by one, so as to separate two adjacent battery cells 200. The transfer frame 110 is provided with multiple first protrusions 111 spaced apart and multiple first grooves 112 spaced apart. The multiple first protrusions 111 and multiple first grooves 112 are arranged opposite to each other. Each insulating shell 120 is provided with a second groove 121 and a second protrusion 122. The multiple first protrusions 111 are correspondingly inserted into the multiple second grooves 121, and the multiple second protrusions 122 of the multiple insulating shells 120 are correspondingly inserted into the multiple first grooves 112, so that each battery cell 200 maintains high stability. This effectively reduces the risk of collisions and friction between battery cells 200, thereby helping to improve the appearance quality of the battery cells 200.

[0040] It should be noted that, through the limiting cooperation of the grooves and protrusions, even if the transfer frame 110 is not fully loaded with battery cells 200, each battery cell 200 inside can maintain a high degree of stability.

[0041] like Figures 3 to 5 As shown, in some embodiments, the transfer frame 110 is provided with a third protrusion 113 in the third direction Z, and each insulating shell 120 is provided with a third groove 123 on one side in the third direction Z; in the first direction X, the third protrusion 113 passes through the third groove 123 of the multiple insulating shells 120 respectively, which can play a further limiting role, thereby further improving the stability of each battery cell 200.

[0042] like Figure 3 and Figure 5 As shown, further, multiple third protrusions 113 are provided, and the multiple third protrusions 113 are spaced apart in the second direction Y. Multiple third grooves 123 are provided in each insulating housing 120, and the multiple third grooves 123 are spaced apart in the second direction Y. In the first direction X, the multiple third protrusions 113 are correspondingly inserted into the multiple third grooves 123 of each insulating housing 120, thereby further improving the stability of each battery cell 200.

[0043] like Figure 4 and Figure 5As shown, in some embodiments, each insulating housing 120 has a fourth groove 124 on one side in the first direction X, and a fourth protrusion 125 on the other side in the first direction X; in two adjacent insulating housings 120, in the third direction Z, the fourth protrusion 125 of one insulating housing 120 passes through the fourth groove 124 of the other insulating housing 120 to limit the relative movement of the two adjacent insulating housings 120 in the second direction Y, thereby further improving the stability of each battery cell 200.

[0044] like Figure 1 and Figure 2 As shown, the transfer frame 110 further includes a fifth protrusion 114 on one side of the first direction X and a fifth groove 115 on the other side of the first direction X. In the two insulating shells 120 that are furthest apart in the first direction X, the fifth protrusion 114 passes through the fourth groove 124 of one of the insulating shells 120 in the third direction Z, and the fourth protrusion 125 of the other insulating shell 120 passes through the fifth groove 115. In this way, when the transfer frame 110 is fully loaded with battery cells 200, it can limit the movement of the first and last insulating shells 120, thereby increasing the stability of the arrangement of multiple insulating shells 120 in the first direction X and improving the stability of each battery cell 200.

[0045] like Figure 2 As shown, in some embodiments, the transfer frame 110 is provided with a plurality of first heat transfer holes 116 penetrating in the first direction X, and the plurality of first heat transfer holes 116 are spaced apart in the second direction Y. This can improve the heat transfer efficiency of the transfer frame 110, thereby shortening the baking time and cooling time of the battery cell 200, and thus helping to improve the production efficiency of the battery cell 200.

[0046] like Figure 2 As shown, in some embodiments, the transfer frame 110 is provided with a plurality of second heat transfer holes 117 extending through in the second direction Y. The plurality of second heat transfer holes 117 are spaced apart in the first direction X. This can further improve the heat transfer efficiency of the transfer frame 110, thereby further shortening the baking time and cooling time of the battery cell 200.

[0047] like Figure 2 As shown, in some embodiments, the transfer frame 110 is provided with a plurality of third heat transfer holes 118 penetrating in the third direction Z. The plurality of third heat transfer holes 118 are spaced apart in the first direction X. This can further improve the heat transfer efficiency of the transfer frame 110, thereby further shortening the baking time and cooling time of the battery cell 200.

[0048] like Figure 4 and Figure 5As shown, in some embodiments, each insulating housing 120 is provided with a plurality of fourth heat transfer holes 126 penetrating in the first direction X, and the plurality of fourth heat transfer holes 126 are spaced apart in the second direction Y.

[0049] like Figure 5 As shown, in some embodiments, each insulating housing 120 is provided with a plurality of fifth heat transfer holes 127 penetrating in the third direction Z, and the plurality of fifth heat transfer holes 127 are spaced apart in the second direction Y. This can further improve the heat transfer efficiency of the insulating housing 120, thereby further shortening the baking time and cooling time of the battery cell 200.

[0050] like Figure 2 and Figure 4 As shown, in some embodiments, the transfer frame 110 is a one-piece molded structure; and / or, each insulating shell 120 is a one-piece molded structure. This facilitates the manufacturing of the transfer frame 110 and the insulating shell 120, and provides higher structural strength and stability, which helps the transfer device 100 to better transfer the battery cells 200.

[0051] For example, the one-piece molded structure can be formed by injection molding, stamping, 3D printing, etc., without any specific limitation.

[0052] like Figure 3 As shown, in some embodiments, the transfer frame 110 is provided with a first handle structure 1191 on one side in the first direction X, and a second handle structure 1192 on the other side in the first direction X. This makes it easier for operators to move the transfer frame 110 and increases its ease of use.
