[0037] Battery cells are a crucial component of battery packs and are typically loaded and transported using shipping frames. However, during transport, battery cells are prone to collisions and friction, affecting their production yield. In the baking process, heat transfer is slow, increasing the baking time. Furthermore, the cooling time after baking also increases due to the slow heat transfer. Additionally, during the vacuum liquid filling process, battery cells are prone to tipping over, and transporting them to the next step in a vacuum environment is difficult, thus impacting production efficiency.
[0038] like Figure 1 As shown, to solve the above-mentioned technical problems, embodiments of this application provide a loading device 100, relating to the field of battery technology, mainly used for loading and transferring battery cells 200. These battery cells 200 are primarily used in battery packs, so as to be indirectly used in electrical devices or energy storage devices through the battery packs. Of course, the battery cells 200 may also be directly used in electrical devices or energy storage devices without using battery packs; no specific limitations are made here.
[0039] For example, electrical devices can be vehicles, mobile phones, portable devices, laptops, ships, spacecraft, electric toys, and power tools. Vehicles can be gasoline-powered cars, natural gas-powered cars, new energy vehicles, etc., and new energy vehicles can be pure electric vehicles, hybrid electric vehicles, and range-extended electric vehicles, etc.; spacecraft can be airplanes, rockets, space shuttles, drones, and spacecraft, etc.; electric toys include stationary or mobile electric toys, such as game consoles, electric car toys, electric ship toys, and electric airplane toys, etc.; power tools can be metal cutting power tools, grinding power tools, assembly power tools, and railway power tools, such as electric drills, electric grinders, electric wrenches, electric screwdrivers, electric hammers, impact drills, concrete vibrators, and electric planers, etc.; energy storage devices include energy storage containers, energy storage cabinets, energy storage power stations, wind power generation devices, solar power generation devices, mobile power devices, and temporary power supply devices, etc.; no specific limitations are made on the types of electrical devices and energy storage devices here.
[0040] It should be noted that the battery cell 200 provided in this embodiment can be a lithium-ion secondary battery cell, a lithium-ion primary battery cell, a lithium-sulfur battery cell, a sodium-lithium-ion battery cell, a sodium-ion battery cell, a magnesium-ion battery cell, etc., and is not specifically limited here. The battery cell 200 can be cylindrical, flat, cuboid, or other shapes, and is not specifically limited here. The battery cell 200 is generally divided into three types according to the packaging method: square battery cell, cylindrical battery cell, and pouch battery cell, and is not specifically limited here.
[0041] like Figure 1 and Figure 2 As shown, the battery cell 200 provided in this embodiment has a first direction X, a second direction Y and a third direction Z that are perpendicular to each other, and includes a shipping frame 110 and a plurality of separators 120.
[0042] The shipping frame 110 has a receiving cavity and an opening. The opening is located on one side of the shipping frame 110 along the third direction Z. At least one side of the shipping frame 110 along the second direction Y is provided with a plurality of first heat-conducting holes 113 that penetrate along the second direction Y. The plurality of first heat-conducting holes 113 are arranged at intervals along the first direction X. A plurality of partitions 120 are disposed in the receiving cavity and are arranged at intervals along the first direction X, so that the receiving cavity is divided into a plurality of placement slots 111 arranged at intervals along the first direction X. Each first heat-conducting hole 113 and each placement slot 111 are arranged opposite to each other along the second direction Y. Each partition 120 is provided with a second heat-conducting hole 121 that penetrates along the first direction X. Each placement slot 111 is used to place a battery cell 200.
[0043] It should be noted that the receiving cavity can be understood as the internal space of the shipping frame 110, and the opening can be understood as the shipping frame 110 opening on the Z side along the third direction, so that the battery cell 200 can be placed in the placement slot 111 from the opening position; the first heat conduction hole 113 penetrating along the second direction Y can be understood as the first heat conduction hole 113 penetrating the shipping frame 110 along the second direction Y; the second heat conduction hole 121 penetrating along the first direction X can be understood as the second heat conduction hole 121 penetrating the partition 120 along the first direction X.
[0044] For example, the material of the shipping frame 110 and / or the material of each separator 120 can be plastic, metal, wood, ceramic, etc., without specific limitations. It should be noted that the electrical insulation between two adjacent battery cells 200 can be achieved by attaching an insulating film to the surface of each battery cell 200, or by using plastic, wood, or ceramic as the material of the shipping frame 110 and each separator 120, without specific limitations.
[0045] It is understood that the shipping device 100 provided in this embodiment has multiple partitions 120 arranged in the receiving cavity of the shipping frame 110. These partitions 120 are spaced apart along the first direction X, dividing the receiving cavity into multiple placement slots 111 spaced apart along the first direction X. Each placement slot 111 is used to place one battery cell 200. This separates adjacent battery cells 200, reducing the possibility of collisions and friction between them. Furthermore, the shipping frame 110 has multiple partitions 120 arranged along at least one side of the second direction Y. A first heat-conducting hole 113 extends in the Y direction, and multiple first heat-conducting holes 113 are arranged at intervals along the first X direction. Simultaneously, each separator 120 is provided with a second heat-conducting hole 121 extending in the first X direction. Each first heat-conducting hole 113 and a placement groove 111 are arranged opposite each other along the second Y direction. This effectively increases the contact area between the battery cell 200 and the external environment, thereby improving the heat transfer efficiency of the battery cell 200. Furthermore, the separator 120 also provides a limiting effect on the battery cell 200, reducing the possibility of the battery cell 200 tipping over. Therefore, the production yield and production efficiency of the battery cell 200 are improved.
[0046] like Figure 6 As shown, in one embodiment, each partition 120 is provided with a plurality of second heat conduction holes 121, which are arranged at intervals along the second direction Y, thereby further increasing the contact area between the battery cell 200 and the external environment, and further improving the heat transfer efficiency of the battery cell 200.
[0047] like Figure 2 and Figure 4As shown, in one embodiment, the shipping frame 110 is provided with a third heat-conducting hole 114 extending through the first direction X on at least one side. The third heat-conducting hole 114 and each placement slot 111 are arranged opposite to each other along the first direction X, thereby further increasing the contact area between the battery cell 200 and the external environment, and further improving the heat transfer efficiency of the battery cell 200.
[0048] It should be noted that the third heat conduction hole 114 that penetrates along the first direction X can be understood as the third heat conduction hole 114 penetrating the shipping frame 110 along the first direction X.
[0049] like Figure 2 and Figure 4 As shown, the shipping frame 110 is further provided with a plurality of third heat conduction holes 114 on at least one side along the first direction X, and the plurality of third heat conduction holes 114 are arranged at intervals along the second direction Y, thereby further increasing the contact area between the battery cell 200 and the external environment, and further improving the heat transfer efficiency of the battery cell 200.
[0050] like Figure 4 and Figure 5 As shown, in one embodiment, the inner side of the shipping frame 110 is provided with a plurality of slots 115 arranged at intervals along the first direction X. Each partition 120 passes through a slot 115 so that each partition 120 is detachably connected to the shipping frame 110. This facilitates the assembly and disassembly of the partitions 120, thereby reducing the assembly and maintenance difficulty of the shipping device 100.
[0051] like Figure 5 As shown, each slot 115 is further provided with an arc-shaped recess 116 at the end of the slot 115 that is close to the opening along the third direction Z. The arc-shaped recess 116 can guide the partition 120 to be accurately inserted into the slot 115, thereby reducing the assembly difficulty of the partition 120.
[0052] like Figure 3 As shown, in one embodiment, the shipping device 100 further includes a plurality of rolling elements 130, which are disposed on the side of the shipping frame 110 away from the opening along the third direction Z. The plurality of rolling elements 130 are arranged at intervals along the circumference of the shipping frame 110. Each rolling element 130 includes a connecting seat 131 and a ball 132. The connecting seat 131 is connected to the shipping frame 110, and the ball 132 is omnidirectionally connected to the connecting seat 131. That is, the ball 132 can roll in three-dimensional space within a 360° range, which makes the shipping device 100 more flexible, especially in the liquid injection process, and easier to move in a vacuum environment, making it more convenient.
[0053] like Figure 5As shown, in one embodiment, each separator 120 is provided with an arc-shaped chamfer 122 on the side of the separator 120 approaching the opening along the third direction Z. This increases the smoothness of the side of the separator 120 approaching the opening along the third direction Z, which can reduce the possibility of appearance damage caused by the separator 120 hitting the battery cell 200 during the process of placing the battery cell 200 in the placement slot 111, and improve the appearance yield of the battery cell 200.
[0054] like Figure 6 As shown, in one embodiment, the dimension of each separator 120 along the first direction X is T (i.e., the thickness of each separator 120 is T), which satisfies: 2mm≤T≤4mm. This not only separates two adjacent battery cells 200, but also makes the gap between two adjacent battery cells 200 smaller, so that there is no need to use a customized taller shipping frame 110 to increase costs (taller means that the dimension of the shipping frame 110 along the third direction Z is larger), and the problem of battery cells 200 tipping over can still be solved.
[0055] For example, the dimension T of each partition 120 along the first direction X can be any value of 2mm, 2.1mm, 2.2mm, 2.5mm, 2.6mm, 2.8mm, 3mm, 3.2mm, 3.5mm, 3.8mm and 4mm or any value of any combination thereof, without any specific limitation herein.
[0056] like Figure 2 and Figure 4 As shown, in one embodiment, the loading device 100 further includes a first handle 141 and a second handle 142. The first handle 141 is connected to one side of the loading frame 110 along the first direction X, and the second handle 142 is connected to the side of the loading frame 110 away from the first handle 141 along the first direction X. This design of handles on opposite sides makes it easier for personnel to move the loading frame 110.
