[0024] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0025] With the trend of iterative technology updates in the industry, battery workshops are required to split whole cell sheets into two halves for use, doubling production capacity. However, continuing with the original whole-cell process and using a single carrier box would increase packaging equipment consumption, leading to reduced packaging production efficiency. To address the problem of low packaging production efficiency caused by increased cell production capacity in the existing technology, this utility model provides a battery cell packaging box and packaging production system.

[0026] Please refer to Figures 1 to 3 As shown, one aspect of the technical solution applied to the present invention, the battery cell 1 packaging box includes a carrying box body 10 and a cover box body 20; the carrying box body 10 includes a carrying plate 11 and a surrounding plate assembly 12, the surrounding plate assembly 12 is arranged on the carrying plate 11 to enclose a carrying space, and at least one partition assembly 13 is provided in the middle of the surrounding plate assembly 12, so that the carrying space is located on both sides of the partition assembly 13 to form a carrying cavity, respectively, for accommodating multiple battery cells 1; the cover box body 20 is used to be mounted on the carrying box body 10 toward the inner bottom surface of the carrying plate 11; wherein, the length value W1 of the carrying cavity satisfies: 262mm≤W1≤266mm; the width value W2 of the carrying cavity satisfies: 131mm≤W2≤133mm.

[0027] In this embodiment, a single partition 131 is used to divide the carrying space into two carrying cavities, each for accommodating two half-cells 1 meeting the aforementioned predetermined length and width. This allows the packaging box to meet the production needs of half-cells 1, and the actual loading capacity is twice the number of full-cells 1 that can be loaded into a single packaging box. This ensures that the production efficiency of the half-cell packaging line is consistent with that of the full-cell packaging line, eliminating the need to double the investment in packaging line equipment and manpower. Furthermore, packaging material consumption is maintained consistent with that of the full-cell process, eliminating the need for additional space to accommodate the additional packaging equipment. This improves the efficiency of the packaging box, reduces packaging box consumption, and lowers production costs, thereby resolving the issue of lower packaging production efficiency resulting from increased production capacity of cell 1 in the prior art.

[0028] like Figure 1 As shown, the enclosure assembly 12 includes two groups of enclosure members 120 arranged opposite to each other along a first direction, and at least one partition assembly 13 is spaced apart between the two groups of enclosure assemblies 12. In this embodiment, there is only one partition assembly 13. In this way, the carrying space can be divided into two carrying cavities, and each carrying cavity can independently carry a half-cell battery cell 1, effectively separating the two half-cell battery cells 1, avoiding direct contact between the battery cells 1, and reducing damage caused by collision or friction during transportation or handling, thereby maximizing the loading quantity within a limited space to meet the packaging process line requirements of the half-cell battery cell 1 and improve the space utilization of the packaging box.

[0029] Specifically, each panel assembly 120 includes two sub-panels 1201 spaced apart along the second direction, with the first and second directions being perpendicular to each other. Thus, the four sub-panels 1201 are spaced apart to enclose a carrying space, and in combination with the spacer assembly 13, ensure optimal arrangement of multiple half-cells 1 within the carrying space. This increases the loading capacity of half-cells 1 compared to conventional packaging boxes, reduces the amount of packaging equipment, and reduces the space required for the packaging line, thereby improving packaging line production efficiency.

[0030] Specifically, the sub-panel 1201 is an L-shaped panel. Thus, the structural design of the sub-panel 1201 allows four sub-panels 1201 to be arranged relative to each other to form a square-shaped load-bearing space; wherein, the two right-angled portions of the L-shaped panel serve as side panels, and the load-bearing plate 11 serves as the bottom panel. By providing the partition assembly 13, each sub-panel 1201 and partition assembly 13 fits tightly against the side of the half-cell battery cell 1 to adapt to the shape and size of the battery cell 1, thereby ensuring the stable arrangement of multiple half-cell battery cells 1 within the packaging box and avoiding mutual squeezing between the battery cells 1. This allows for more efficient loading of more half-cell battery cells 1, thereby improving packaging density and efficiency.

[0031] To facilitate the removal of half-cells 1, a first escape opening 1202 is provided between the outer walls of the two sub-enclosures 1201 in each set of enclosures 120. The opening size L1 of the first escape opening 1202 along the second direction satisfies the following condition: 85mm≤L1≤90mm. This facilitates the operation of operators or automated equipment when loading and unloading the cell 1. The cell 1 will not wobble within the carrier box 10 due to an overly large first escape opening 1202, nor will the operation become more difficult due to the first escape opening 1202 being too narrow. At the same time, by precisely controlling the size of the first escape opening 1202, waste of material from the carrier box 10 can be reduced, while ensuring the structural strength of the packaging box and achieving effective cost control.

[0032] Optionally, when there is only one partition assembly 13, a second avoidance opening 14 is respectively provided between the outer side walls of the two sets of enclosure members 120 and the outer side walls of the partition assembly 13, and the opening size L2 of the second avoidance opening 14 along the first direction satisfies: 65mm≤L2≤70mm. In this way, the design of the second avoidance opening 14 enables operators or automated equipment to more conveniently remove or place the battery cells 1 from the carrier box body 10 in a carrier cavity containing multiple half-cell battery cells 1, and the specific opening size ensures that it can accommodate the size and operating space requirements of the half-cell battery cells 1, while at the same time not affecting the structural strength and stability of the packaging box due to an overly large opening. In addition, the precise definition of the opening size facilitates rapid positioning and grasping, reduces damage to the battery cells 1 and operating time during the packaging process, and improves packaging production efficiency.

[0033] Optionally, when there are multiple partition assemblies 13, a third avoidance opening is provided between the outer side walls of two adjacent partition assemblies 13, and the opening size L3 of the third avoidance opening along the first direction satisfies: 65mm≤L3≤70mm. Similarly, the design of the third avoidance opening enables operators or automated equipment to more conveniently remove or place the battery cells 1 from the carrier box body 10 in a carrier cavity containing multiple half-cell battery cells 1, and the specific opening size ensures that it can accommodate the size and operating space requirements of the half-cell battery cells 1, while not affecting the structural strength and stability of the packaging box due to an overly large opening. In addition, the precise definition of the opening size facilitates rapid positioning and grasping, reduces damage to the battery cells 1 and operating time during the packaging process, and improves packaging production efficiency.

[0034] It should be noted that if Figure 2 As shown, in the present application, a first avoidance groove is provided on the carrier plate 11 corresponding to the first avoidance opening 1202, and the first avoidance groove is connected to the first avoidance opening 1202, further facilitating the operation of operators or automated equipment when loading and unloading the battery cells 1. A second avoidance groove is provided on the carrier plate 11 corresponding to the second avoidance opening 14, and the second avoidance groove is connected to the second avoidance opening 14, further facilitating operators or automated equipment to more conveniently remove or insert the battery cells 1 from the carrier box body 10.

[0035] Specifically, the partition assembly 13 includes two mounting plates 130 and a partition 131; the two mounting plates 130 are arranged relative to each other on the supporting plate 11 along the second direction; the two ends of the partition 131 are respectively connected to the two mounting plates 130, so that a supporting cavity is formed on both sides of the partition 131. In the above arrangement, the two right-angled portions formed by the partition 131 connecting to the two mounting plates 130 respectively serve as side panels. In this way, when the supporting cavity is loaded with multiple half-cell battery cells 1, the right-angled portions connecting the two mounting plates 130 and the partition 131 and the two sub-enclosures 1201 are respectively tightly fitted with the sides of the half-cell battery cells 1 to achieve the loading and positioning of multiple half-cell battery cells 1. At the same time, the partition 131 not only effectively divides the supporting space, but also separates multiple half-cell battery cells 1, optimizing the internal space utilization of the packaging box and avoiding direct contact between the half-cell battery cells 1.

[0036] In this embodiment, the height H of the enclosure assembly 12 and the partition assembly 13 in the vertical direction both satisfy: 40mm≤H≤50mm. In this way, by precisely controlling the height of the enclosure assembly 12 and the partition assembly 13 without affecting the normal operation of the packaging line, the battery cell 1 packaging box can be maximized within the limited vertical space, thereby reducing space waste during transportation and storage, improving logistics efficiency, and saving costs. In addition, the above-mentioned specific height range helps to maintain the structural stability of the packaging box, prevent structural deformation caused by excessive height or mutual collision between battery cells 1 during transportation, and avoid the inability to effectively isolate external impacts due to too low a height, thereby ensuring the safety of the battery cell 1 in the packaging box.

[0037] In this embodiment, the carrier box body 10 and the cover box body 20 are both made of insulating materials. During the production, transportation and storage process, the battery cell 1 may encounter the risk of electrostatic discharge (ESD) or short circuit. In this configuration, the use of insulating materials can effectively prevent these risks, protect the battery cell 1 from damage caused by charge accumulation or accidental contact, and improve the safety of the entire battery cell 1 packaging box and packaging production system. In addition, it can prevent current from flowing in unintended paths, avoiding current leakage between battery cells 1 or between battery cell 1 and the packaging box. This is a very important protective measure for sensitive electronic components such as battery cells 1.

[0038] Another aspect of the technical solution applied to the present utility model is as follows: Figure 4 As shown, a packaging production system is provided, including the battery cell 1 packaging box mentioned above.

[0039] In this embodiment, the packaging production system process includes, in sequence, a sorting machine conveying a plurality of carrier boxes 10, manually packaging (a plurality of half-cell battery cells 1 are loaded into the carrier boxes 10 respectively), and then grading and caching (the cover box 20 is placed on the carrier box 10). After completion, the plurality of packaging boxes are automatically packed, and the packed boxes are then palletized, thereby completing the entire packaging production line.

[0040] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects:

[0041] The battery cell 1 packaging box includes a carrier box body 10 and a cover box body 20; the carrier box body 10 includes a carrier plate 11 and a panel assembly 12. The panel assembly 12 is arranged on the carrier plate 11 to enclose a carrier space. At least one partition assembly 13 is provided in the middle of the panel assembly 12, so that the carrier space is located on both sides of the partition assembly 13 to form a carrier cavity for accommodating multiple battery cells 1 respectively; the cover box body 20 is used to be mounted on the carrier box body 10 toward the inner bottom surface of the carrier plate 11; wherein the length W1 of the carrier cavity satisfies the following conditions: 262mm≤W1≤266mm; the width W2 of the carrier cavity satisfies the following conditions: 131mm≤W2≤133mm. In this embodiment, there is a single partition 131, so that the carrier space is divided into two carrier cavities for accommodating two half-cell battery cells 1 of the above-mentioned predetermined length and width. In this way, the packaging box can adapt to the production needs of half-cell battery cells 1, and the actual loading capacity reaches twice the number of whole-cell battery cells 1 loaded in the original single packaging box. In this way, the production efficiency of the half-cell process packaging line is ensured to be consistent with the production efficiency of the whole-cell process packaging line, and there is no need to increase the investment in packaging line equipment and manpower exponentially. At the same time, the consumption of packaging materials can also be consistent with the whole-cell process, and there is no need to increase additional space for placing additional packaging equipment, thereby improving the utilization efficiency of the packaging box, reducing the consumption of the packaging box, and reducing production costs, thereby solving the problem of low packaging production efficiency caused by the increase in the production capacity of the battery cell 1 in the prior art.
