Description

Technical Field

[0001] The utility model relates to the technical field of battery core shell transportation, in particular to a packaging box. Background Art

[0002] With the rapid development of the lithium battery industry, the requirements for battery automation production level are gradually increasing, and at the same time, it is also necessary to reduce unnecessary waste in the production line. At present, the incoming aluminum shells of battery cells are usually packaged in carton thermoplastic film and paper panels. At the same time, the incoming materials need to be unpacked and unpacking is difficult. After unpacking, they need to be stacked on blister trays and then delivered to the production line. This requires the cost of repackaging of one-time packaging, as well as the investment and management costs of turnover packaging within the factory. Utility Model Content

[0003] The main purpose of the utility model is to provide a packaging box, aiming to improve the problem of high repackaging cost of the existing disposable packaging materials of the battery core aluminum shell.

[0004] In a first aspect, the present application provides a packaging box, the packaging box comprising:

[0005] A box structure is formed with a receiving cavity; and

[0006] A partition structure is arranged in the accommodating cavity, and the partition structure divides the accommodating cavity into a plurality of accommodating grooves, and the accommodating grooves are used to accommodate the battery cell shells.

[0007] In the technical solution of the embodiment of the present application, by setting a reasonable number and spacing of the accommodating grooves, the battery cell shell accommodated by the packaging box can be consistent with the original paper box packaging. At the same time, the packaging box can not only be recycled as a transportation packaging, but also can replace the blister tray. After transporting the incoming materials, the packaging box can be loaded with the battery cell shell and directly put on line without turning the package over. This reduces the quality problems of the battery cell shell caused by turning over, such as scratches, nicks, burrs, etc. on the battery cell shell, and realizes the streamlining of unpacking manpower. For the battery cell shell manufacturers, it can reduce the packaging actions and at the same time reduce the packaging costs, save energy and protect the environment, and meet the requirements of sustainable development.

[0008] In some embodiments, a buffer protrusion is provided on at least a portion of the side wall of the receiving groove.

[0009] At this time, since a buffer protrusion is provided on the side wall of the accommodating groove, after the battery cell shell is installed in place, the buffer protrusion can press against the battery cell shell, playing a role of buffering and limiting, thereby stably limiting the battery cell shell in the accommodating groove, and preventing the battery cell shell from being damaged by vibration and collision with the partition structure during transportation.

[0010] In some embodiments, the cross-section of the buffer protrusion gradually decreases in a direction toward the middle of the receiving groove.

[0011] At this time, in the direction toward the middle of the accommodating groove, the buffer protrusion can apply a pressing force to the battery cell shell, and in this direction, the cross-sectional area of ​​the buffer protrusion gradually decreases, that is, the contact area between the buffer protrusion and the battery cell shell is reduced, thereby reducing the friction resistance encountered when removing the battery cell shell, making the removal process easier and faster.

[0012] In some embodiments, the buffer protrusion is disposed on the partition structure.

[0013] At this time, setting the buffer protrusion on the partition structure can reduce the processing of the box structure and reduce the processing complexity of the box structure. Since it does not need to serve as a mounting base for the buffer protrusion, there are many material options for the box structure. For example, a material with low density and light weight can be selected to facilitate placement and transportation.

[0014] In some embodiments, a mounting hole is formed on the partition structure through two adjacent accommodating grooves;

[0015] A buckle structure is arranged in the mounting hole, and the buckle structure includes two buckle parts which buckle with each other and are respectively exposed in the two receiving grooves, and the buckle part includes the buffer protrusion.

[0016] At this time, the mounting hole serves as a mounting base to connect the two receiving grooves, and the two snap-fitting parts of the snap-fit ​​structure can be snap-fitted and connected through the mounting hole, and are respectively exposed in the two receiving grooves, and the snap-fitting part includes the buffer protrusion, thereby realizing a detachable connection between the buffer protrusion and the partition structure. At the same time, the installation of the two buffer protrusions can be completed by snapping together once, thereby improving the installation efficiency of the buffer protrusion.

[0017] In some embodiments, a plurality of the mounting holes are arranged at intervals in the height direction of the partition structure, and the snap-fit ​​structure can be selectively arranged in any of the mounting holes.

[0018] At this time, by opening a plurality of the mounting holes along the height direction of the partition structure, the snap-fit ​​structure can be selectively installed in one or more of the mounting holes, so that the snap-fit ​​structure can be adjusted in height according to the specifications of the battery cell shell, thereby improving the applicability of the packaging box to battery cell shells of multiple specifications.

[0019] In some embodiments, the partition structure includes a plurality of first partition plates and a second partition plate vertically disposed in the accommodating cavity, and the plurality of first partition plates and the plurality of second partition plates are staggeredly connected;

[0020] Two adjacent first partition plates and two adjacent second partition plates together form at least a portion of the accommodating groove, and / or the side wall of the accommodating cavity and the corresponding first partition plates and second partition plates together form at least a portion of the accommodating groove.

[0021] At this time, the partition structure is formed by staggeredly connecting multiple first partition plates and multiple second partition plates, which can divide the accommodating cavity to the maximum extent, and the first partition plates and the second partition plates occupy relatively small space, so as to separate as many accommodating slots as possible, that is, as many battery cell shells as possible can be accommodated, thereby ensuring transportation efficiency.

[0022] In some embodiments, the first partition plate and / or the second partition plate are hollowed out; and / or

[0023] The material of the first partition plate and / or the second partition plate includes polyoxymethylene plastic.

[0024] At this time, by setting the first partition plate and the second partition plate to be hollow, the weight of the packaging box can be reduced to a great extent. Lighter packaging weight means that more battery cell shells can be loaded in the same batch of transportation, which also means that manual stacking or unloading is easier. The first partition plate and the second partition plate are made of polyformaldehyde plastic, which can obtain greater supporting strength and are not easy to deform.

[0025] In some embodiments, a first card slot opening along the height direction is formed on the first partition plate, and correspondingly, a second card slot opening along the height direction is formed on the second partition plate;

[0026] The first partition plate and the second partition plate are plug-connected via the first card slot and the second card slot.

[0027] At this time, the first partition plate and the second partition plate are plugged into each other to facilitate the disassembly and assembly of the partition structure. When needed, the partition structure can be quickly assembled. The plug-in connection between the first card slot and the second card slot makes the partition structure as a whole more stable. When not needed, the partition structure can be split into multiple first partition plates and multiple second partition plates, which can be stacked and stored, reducing space occupancy.

[0028] In some embodiments, a positioning mark portion is formed on the first partition plate, and the positioning mark portion and the first card slot are arranged in a positional manner in the height direction; and / or,

[0029] The second partition plate is formed with a positioning marking portion, and the positioning marking portion and the second clamping slot are arranged in a positioning manner in the height direction.

[0030] At this time, by setting the alignment calibration part on the first partition plate and the second partition plate, after the first partition plate and the second partition plate are plugged and connected through the first card slot and the second card slot, it can be determined whether the first partition plate is vertically plugged in by identifying the alignment calibration part on the first partition plate and the second partition plate, and it can be determined whether the second partition plate is vertically plugged in by identifying the alignment calibration part on the second partition plate and the first partition plate, thereby preventing the battery cell casing from being unable to be inserted into the corresponding receiving slot due to the skewed plugging of the first partition plate and the second partition plate.

[0031] In some embodiments, a plurality of first card slots are provided along the length direction of the first partition plate, and a plurality of second partition plates can be selectively inserted into any of the first card slots of the first partition plate; and / or,

[0032] A plurality of the second card slots are arranged along the length direction of the second partition plate, and a plurality of the first partition plates can be selectively inserted into any of the second card slots of the second partition plate.

[0033] At this time, by setting a plurality of the first card slots, the second partition plate can select the corresponding first card slot to be inserted, thereby changing the interval between two adjacent second partition plates. Similarly, by setting a plurality of the second card slots, the first partition plate can select the corresponding second card slot to be inserted, thereby changing the interval between two adjacent first partition plates. By adjusting the interval between the two first partition plates and / or the second partition plates, the specifications of the accommodating slot can be adjusted, so that the packaging box can adapt to the packaging needs of battery cell shells of different specifications.

[0034] In some embodiments, an identification unit is provided on the box structure, and the identification unit includes at least one of a barcode identification unit, a supply information identification unit, an online direction identification unit, and a robot grasping identification unit.

[0035] At this time, through the setting of the barcode recognition unit, it is convenient to identify the model, specification, quantity, batch and other information of the battery shell packaged in the packaging box; through the setting of the supply information recognition unit, it is convenient to reflect the brand logo of the supplier; through the setting of the online direction recognition unit, it is convenient for the operator or the robot to put the packaging box online to the production line according to the direction of the mark, which has a certain anti-fool function; and through the setting of the robot recognition unit, it is convenient for the robot to accurately grasp the packaging box, and locate the position of the battery cell shell in the packaging box according to the robot recognition unit, so as to accurately grasp the battery cell shell from the receiving slot.

[0036] In some embodiments, the material of the box structure includes polypropylene plastic foam material.

[0037] At this time, the box structure is made of polypropylene plastic foam material, which has the characteristics of light weight, strong temperature resistance and good buffering performance. The box structure is not easy to scratch the battery shell and can protect the internal battery shell.

[0038] In some embodiments, a vent hole connected to the accommodating cavity is formed on the side wall of the box structure.

[0039] At this time, through the setting of the air hole, the accommodating cavity can be connected to the external atmosphere. When grabbing the upper packaging box from a plurality of tightly stacked packaging boxes, it can be easily grabbed without lifting the adjacent lower packaging box, thereby preventing the position of the lower packaging box from changing, thereby enhancing the safety of the products in the box.

[0040] In some embodiments, a positioning protrusion is formed at the bottom of the box structure, and the positioning protrusion is arranged in alignment with the opening of the accommodating cavity.

[0041] At this time, by aligning the positioning protrusion with the opening of the accommodating cavity, after the two packaging boxes are stacked, the positioning protrusion of the packaging box on the upper layer will be aligned and inserted into the accommodating cavity of the packaging box on the lower layer, thereby generating a limit along the horizontal direction of the packaging box, which can prevent the packaging box on the upper layer from sliding from a high place, thereby improving the safety of the transportation process.

[0060] With the rapid development of the lithium battery industry, the requirements for battery automation production level are gradually increasing, and at the same time, it is also necessary to reduce unnecessary waste in the production line. At present, aluminum shell incoming materials use carton thermoplastic film and paper fence incoming materials. The materials need to be unpacked and unpacking is difficult. After unpacking, they need to be stacked on blister trays and then delivered to the production line. On the one hand, it is necessary to bear the cost of flipping disposable packaging, as well as the investment and management costs of turnover packaging in the factory. On the other hand, the flipping action itself does not add value, and there are quality risks in the flipping process. At the same time, the use of disposable packaging is not environmentally friendly, affects the on-site 5S management, and does not conform to the green and low-carbon corporate concept.

[0061] Based on the above considerations, it is necessary to design and develop a set of battery cell shell packaging that can be directly put into production and can be recycled multiple times.

[0062] According to some embodiments of the present application, please refer to Figure 1 and Figure 2 ,in, Figure 1 A schematic diagram of the three-dimensional structure of an embodiment of a packaging box provided by the utility model; Figure 2 for Figure 1 Schematic diagram of the top view structure of the packaging box.

[0063] An embodiment of the present application provides a packaging box 100, which aims to improve the problem of high repackaging cost of disposable packaging materials of existing battery cell aluminum shells. The packaging box 100 includes a box structure 1 and a partition structure 2. The box structure 1 is formed with a accommodating cavity 11; the partition structure 2 is arranged in the accommodating cavity 11, and the partition structure 2 divides the accommodating cavity 11 into a plurality of accommodating grooves 111, and the accommodating grooves 111 are used to accommodate the battery cell shells.

[0064] Among them, the specifications and sizes of the box structure 1 can be in many cases. For example, one specification of the box structure 1 is 606*494*240mm. In this case, a T1111 pallet with a specification of 1100*1100*165mm can load four groups of packaging boxes 100, and each group of packaging boxes 100 can include multiple stacked packaging boxes 100. At the same time, the specifications and sizes of the accommodating cavity 11 and the accommodating groove 111 can also be in many cases, as long as they can meet the single carrying capacity requirements, which will not be elaborated in this embodiment; the function of the partition structure 2 is mainly to separate the accommodating cavity 11, and its specific structural form can be in various forms. For example, the partition structure 2 can be directly integrated with the box structure 1, or it can be detachably connected to the box structure 1. This embodiment does not limit this, as long as the separated accommodating cavity 11 can accommodate a battery cell shell of corresponding specifications.

[0065] In the technical solution of the embodiment of the present application, by setting a reasonable number and spacing of the accommodating grooves 111, the battery cell shell accommodated by the packaging box 100 can be consistent with the original paper box packaging. At the same time, the packaging box 100 can not only be recycled as a transportation packaging, but also can replace the blister tray. After transporting the incoming materials, the packaging box 100 can be loaded with the battery cell shell and directly put on line without turning the package over, thereby reducing the quality problems of the battery cell shell caused by turning over the package, such as scratches, nicks, burrs, etc. on the battery cell shell, thereby streamlining the unpacking manpower. For the battery cell shell manufacturers, the packaging actions can be reduced, and the packaging cost can be reduced, which is energy-saving and environmentally friendly and meets the requirements of sustainable development. Moreover, different battery cell shell suppliers can share the same packaging box 100 to avoid packaging investment redundancy caused by fluctuations in the production of battery cell shells. The packaging box 100 can be uniformly placed and managed by a third-party packaging supplier to truly realize packaging sharing.

[0066] See also Figure 1 and Figure 5 ,in, Figure 5 for Figure 1Schematic diagram of the enlarged structure of part A in the figure, in some embodiments, a buffer protrusion 241 is provided on at least part of the side wall of the accommodating groove 111.

[0067] Among them, the accommodating groove 111 is adapted to the aluminum shell of the battery cell, which generally has four side walls. At least part of the side walls of the accommodating groove 111 refer to one side wall, two side walls, three side walls or four side walls. The function of the buffer protrusion 241 is to abut the battery cell shell, thereby eliminating the frame amount between the battery cell shell and the accommodating groove 111. Its specific structure can have many forms. A single one can be set for each side wall of the accommodating groove 111, or multiple ones can be set. However, the buffer protrusion 241 first needs to have a certain buffering capacity, which means that it can be deformed. Secondly, the hardness of the buffer protrusion 241 needs to be less than that of the battery cell shell to prevent the battery cell shell from being scratched. It can be made of many materials, and this embodiment does not limit this.

[0068] According to the above technical solution, since a buffer protrusion 241 is provided on the side wall of the accommodating groove 111, after the battery cell shell is installed in place, the buffer protrusion 241 can press against the battery cell shell, playing a role of buffering and limiting, thereby stably restricting the battery cell shell in the accommodating groove 111, and preventing the battery cell shell from being damaged by vibration and collision with the partition structure 2 during transportation.

[0069] In some embodiments, the cross-section of the buffer protrusion 241 gradually decreases in a direction toward the middle of the receiving groove 111 .

[0070] The direction toward the middle of the accommodating groove 111 refers to the direction from the side wall of the accommodating groove 111 to the center of the accommodating groove 111 within the cross section of the accommodating groove 111, that is, the direction of the force exerted by the buffer protrusion 241 on the battery cell shell after the battery cell shell is placed.

[0071] According to the above technical solution, in the direction toward the middle of the accommodating groove 111, the buffer protrusion 241 can apply a pressing force to the battery cell shell, and in this direction, the cross-sectional area of ​​the buffer protrusion 241 gradually decreases, that is, the contact area between the buffer protrusion 241 and the battery cell shell is reduced, thereby reducing the friction resistance encountered when removing the battery cell shell, making the removal process easier and faster.

[0072] In some embodiments, the buffer protrusion 241 is disposed on the partition structure 2 .

[0073] According to the above technical solution, the buffer protrusion 241 is arranged on the partition structure 2, which can reduce the processing of the box structure 1 and reduce the processing complexity of the box structure 1. Since it is not necessary to serve as a mounting base for the buffer protrusion 241, there are many material options for the box structure 1. For example, a material with low density and light weight can be selected to facilitate placement and transportation.

[0074] See also Figure 4 and Figure 5 ,in, Figure 4 for Figure 1 Schematic diagram of the assembly structure of the first partition plate 21 and the second partition plate 22. In some embodiments, a mounting hole 23 is formed on the partition structure 2 through two adjacent receiving grooves 111; a snap-fit ​​structure 24 is provided in the mounting hole 23, and the snap-fit ​​structure 24 includes two snap-fitting parts that are snapped together and respectively exposed in the two receiving grooves 111, and the snap-fitting parts include a buffer protrusion 241.

[0075] Among them, the snap-on structure 24 includes two snap-on parts that snap into each other, and the two snap-on parts can be snap-on connected from the two accommodating grooves 111 through the mounting holes 23 respectively, which means that the two snap-on parts are detachable, and there are many snap-on connection methods of the two snap-on parts, which are not limited in the embodiments of the present application; and the snap-on part includes the buffer protrusion 241, which means that the snap-on part can be composed of the buffer protrusion 241 as a whole, or can partially include the buffer protrusion 241.

[0076] According to the above technical solution, the mounting hole 23 serves as a mounting base to connect the two receiving grooves 111, and the two snap-fitting parts of the snap-fit ​​structure 24 can be snap-fitted and connected through the mounting hole 23, and are respectively exposed in the two receiving grooves 111, and the snap-fitting part includes a buffering protrusion 241, thereby realizing a detachable connection between the buffering protrusion 241 and the partition structure 2. At the same time, the installation of the two buffering protrusions 241 can be completed by snapping together once, thereby improving the installation efficiency of the buffering protrusion 241.

[0077] Specifically, the buffer protrusion 241 includes a rubber buckle. The rubber buckle has a relatively low hardness and a certain elastic deformation ability, and can protect the battery cell shell.

[0078] In some embodiments, a plurality of mounting holes 23 are arranged at intervals in the height direction of the partition structure 2 , and the snap-fit ​​structure 24 can be selectively arranged in any mounting hole 23 .

[0079] The height direction of the partition structure 2 is the direction of the opening of the accommodating groove 111. The buckle structure 24 can be selectively set in any mounting hole 23, which means that among the mounting holes 23 at different heights, one of them can be selected to set the buckle structure 24, two of them can be selected to set the buckle structure 24, or even multiple of them can be selected to set the buckle structure 24. This embodiment is not limited to this.

[0080] According to the above technical solution, by opening a plurality of mounting holes 23 along the height direction of the partition structure 2, a snap-fit ​​structure 24 can be selectively installed in one or more of the mounting holes 23, so that the snap-fit ​​structure 24 can be adjusted in height according to the specifications of the battery cell shell, thereby improving the applicability of the packaging box 100 to battery cell shells of multiple specifications.

[0081] See also Figure 4 In some embodiments, the partition structure 2 includes a plurality of first partition plates 21 and a second partition plate 22 vertically disposed in the accommodating cavity 11, and the plurality of first partition plates 21 and the plurality of second partition plates 22 are staggeredly connected;

[0082] Two adjacent first partition plates 21 and two adjacent second partition plates 22 together form at least a portion of the accommodating groove 111 , and / or the side wall of the accommodating cavity 11 and the corresponding first partition plates 21 and second partition plates 22 together form at least a portion of the accommodating groove 111 .

[0083] Among them, multiple first partition plates 21 and multiple second partition plates 22 are arranged vertically, and at the same time, multiple first partition plates 21 and multiple second partition plates 22 are staggeredly connected, which means that multiple first partition plates 21 are arranged relatively at intervals along the thickness direction of the second partition plates 22, and multiple second partition plates 22 are arranged relatively at intervals along the thickness direction of the first partition plates 21, and any first partition plate 21 is staggeredly connected to multiple second partition plates 22, and any second partition plate 22 is staggeredly connected to multiple first partition plates 21.

[0084] It should be noted that the above two parallel technical features "two adjacent first partition plates 21 and two second partition plates 22 enclose at least part of the receiving groove 111" and "the side wall of the receiving cavity 11 and the corresponding first partition plates 21 and second partition plates 22 enclose at least part of the receiving groove 111" can be set selectively or simultaneously. When set simultaneously, it means that the partition structure 2 can not only separate part of the receiving groove 111 through its own first partition plate 21 and second partition plate 22, but also separate the remaining part of the receiving groove 111 with the assistance of the side wall of the receiving cavity 11.

[0085] According to the above technical solution, the partition structure 2 is formed by staggered connection of multiple first partition plates 21 and multiple second partition plates 22, which can divide the accommodating cavity 11 to the maximum extent, and the first partition plates 21 and the second partition plates 22 occupy relatively small space, and can separate as many accommodating slots 111 as possible, that is, can accommodate as many battery cell shells as possible, thereby ensuring transportation efficiency.

[0086] In some embodiments, the first partition plate 21 and / or the second partition plate 22 are hollowed out; and / or

[0087] The material of the first partition plate 21 and / or the second partition plate 22 includes polyoxymethylene plastic.

[0088] Among them, “the first partition plate 21 and / or the second partition plate 22 are hollowed out” includes three solutions, namely, “the first partition plate 21 is hollowed out”, “the second partition plate 22 is hollowed out” and “the first partition plate 21 and the second partition plate 22 are both hollowed out”;

[0089] “The material of the first partition plate 21 and / or the second partition plate 22 includes polyformaldehyde plastic” includes three options, namely, “the material of the first partition plate 21 includes polyformaldehyde plastic”, “the material of the second partition plate 22 includes polyformaldehyde plastic” and “the material of the first partition plate 21 and the second partition plate 22 includes polyformaldehyde plastic”.

[0090] It should be noted that the above two parallel technical features "the first partition plate 21 and / or the second partition plate 22 are hollowed out" and "the material of the first partition plate 21 and / or the second partition plate 22 includes polyformaldehyde plastic" can be set selectively or simultaneously.

[0091] According to the above technical solution, by setting the first partition plate 21 and the second partition plate 22 to be hollow, the weight of the packaging box 100 can be reduced to a great extent. Lighter packaging weight means that more battery cell shells can be loaded in the same batch of transportation, which also means that manual stacking or unloading is easier. The first partition plate 21 and the second partition plate 22 are made of polyformaldehyde plastic, which can obtain greater supporting strength and are not easy to deform.

[0092] Please continue reading Figure 4 In some embodiments, a first card slot 211 opening along its height direction is formed on the first partition plate 21, and correspondingly, a second card slot 221 opening along its height direction is formed on the second partition plate 22; the first partition plate 21 and the second partition plate 22 are plug-connected through the first card slot 211 and the second card slot 221.

[0093] Among them, the first card slot 211 opens along the height direction of the first partition plate 21 and should also pass through along the thickness direction of the first partition plate 21. The second card slot 221 opens along the height direction of the second partition plate 22 and should also pass through along the thickness direction of the second partition plate 22. Only in this way can the first card slot 211 and the second card slot 221 be plugged into each other.

[0094] According to the above technical solution, the first partition plate 21 and the second partition plate 22 are plugged into each other to facilitate the disassembly and assembly of the partition structure 2. When needed, the partition structure 2 can be quickly assembled. The plug-in connection between the first card slot 211 and the second card slot 221 makes the partition structure 2 as a whole more stable. When not needed, the partition structure 2 can be split into multiple first partition plates 21 and multiple second partition plates 22, which can be stacked and stored, reducing space occupancy.

[0095] In some embodiments, a positioning mark portion 25 is formed on the first partition plate 21, and the positioning mark portion 25 is arranged to be aligned with the first slot 211 in the height direction; and / or,

[0096] A positioning marking portion 25 is formed on the second partition plate 22 , and the positioning marking portion 25 and the second clamping slot 221 are arranged in a positional alignment in the height direction.

[0097] Among them, the alignment calibration part 25 is aligned with the first card slot 211 or the second card slot 221 in the height direction, which means that if the first partition plate 21 and the second partition plate 22 are correctly inserted into place, the first partition plate 21 and the second partition plate 22 can point to the corresponding alignment calibration part 25. The alignment calibration part 25 can be a mark or a protruding structure or a concave structure, and the present application does not limit this.

[0098] It should be noted that the above two parallel technical features "a positioning calibration portion 25 is formed on the first partition plate 21, and the positioning calibration portion 25 and the first card slot 211 are aligned in the height direction" and "a positioning calibration portion 25 is formed on the second partition plate 22, and the positioning calibration portion 25 and the second card slot 221 are aligned in the height direction" can be set one by one or at the same time. Obviously, the effect of setting them at the same time is better.

[0099] According to the above technical scheme, by setting a positioning calibration part 25 on the first partition plate 21 and the second partition plate 22, after the first partition plate 21 and the second partition plate 22 are plugged and connected through the first card slot 211 and the second card slot 221, it can be determined whether the first partition plate 21 is vertically plugged in by identifying the positioning calibration part 25 on the first partition plate 21 and the second partition plate 22, and it can be determined whether the second partition plate 22 is vertically plugged in by identifying the positioning calibration part 25 on the second partition plate 22 and the first partition plate 21, thereby preventing the battery cell casing from being unable to be loaded into the corresponding receiving slot 111 due to the skewed plugging of the first partition plate 21 and the second partition plate 22.

[0100] In some embodiments, a plurality of first slots 211 are provided along the length direction of the first partition plate 21, and a plurality of second partition plates 22 can be selectively inserted into any first slot 211 of the first partition plate 21; and / or,

[0101] A plurality of second slots 221 are provided along the length direction of the second partition plate 22 , and a plurality of first partition plates 21 can be selectively inserted into any second slot 221 of the second partition plate 22 .

[0102] It should be noted that, multiple second partition plates 22 can be optionally inserted into any first card slot 211 of the first partition plate 21, which means that one first card slot 211 can be reserved between two adjacent partition plates, or two first card slots 211 can be reserved, which are set as multiple first card slots, in order to change the spacing between two adjacent second partition plates 22; similarly, multiple first partition plates 21 can be optionally inserted into any second card slot 221 of the second partition plate 22, which means that one second card slot 221 can be reserved between two adjacent partition plates, or two second card slots 221 can be reserved, which are set as multiple second card slots, in order to change the spacing between two adjacent first partition plates 21.

[0103] According to the above technical solution, by setting a plurality of first card slots 211, the second partition plate 22 can select the corresponding first card slot 211 to be inserted, thereby changing the interval between two adjacent second partition plates 22. Similarly, by setting a plurality of second card slots 221, the first partition plate 21 can select the corresponding second card slot 221 to be inserted, thereby changing the interval between two adjacent first partition plates 21. By adjusting the interval between the two first partition plates 21 and / or the second partition plates 22, the specifications of the accommodating groove 111 are adjustable, so that the packaging box 100 can adapt to the packaging needs of battery cell shells of different specifications.

[0104] See also Figure 1 and Figure 3 ,in, Figure 3 for Figure 1 The front view structural diagram of the packaging box 100 is shown in FIG. 1 . In some embodiments, an identification unit 14 is provided on the box structure 1, and the identification unit 14 includes at least one of a barcode identification unit 141, a supply information identification unit 142, an online direction identification unit 144 and a robot grasping identification unit.

[0105] Among them, the barcode recognition unit 141 usually includes a barcode or a QR code; the supply information recognition unit 142 usually includes the brand logo of the supplier; the online direction recognition unit 144 usually includes a pointing arrow or other structure that can determine the direction; the manipulator grasping recognition unit usually includes a grasping recess or a manipulator recognition calibration block.

[0106] It should be noted that the identification unit 14 includes at least one of the barcode identification unit 141, the supply information identification unit 142, the online direction identification unit 144 and the robot grasping identification unit, which means that the identification unit 14 may include one, two or even all of the barcode identification unit 141, the supply information identification unit 142, the online direction identification unit 144 and the robot grasping identification unit.

[0107] According to the above technical scheme, through the setting of the barcode recognition unit 141, it is convenient to identify the model, specification, quantity, batch and other information of the battery shell packaged in the packaging box 100; through the setting of the supply information recognition unit 142, it is convenient to reflect the brand logo of the supplier; through the setting of the online direction recognition unit 144, it is convenient for the operator or the robot to put the packaging box 100 online to the production line according to the marked direction, which has a certain anti-mistake function; and through the setting of the robot recognition unit 143, it is convenient for the robot to accurately grasp the packaging box 100, and locate the position of the battery cell shell in the packaging box 100 according to the robot recognition unit 143, so as to accurately grasp the battery cell shell from the accommodating slot 111.

[0108] In some embodiments, the material of the box structure 1 includes polypropylene plastic foam material.

[0109] According to the above technical solution, the box structure 1 is made of polypropylene plastic foam material. The box structure 1 has the characteristics of light weight, strong temperature resistance and good buffering performance. The box structure 1 is not easy to scratch the battery shell and can play a role in protecting the internal battery shell.

[0110] See also Figure 1 and Figure 3 In some embodiments, an air hole 12 connected to the accommodating cavity 11 is formed on the side wall of the box structure 1.

[0111] Among them, the function of the air hole 12 is mainly to balance the pressure of the accommodating chamber 11 and the external atmosphere. It can be set in multiple locations, for example, it can be on the side wall of the box structure 1, or around the bottom of the box structure 1. The shape and size of the air hole 12 can be in various situations, as long as it can meet the requirement of balancing the air pressure without destroying the overall structural strength of the box structure 1.

[0112] According to the above technical solution, through the setting of the air hole 12, the accommodating cavity 11 can be connected to the external atmosphere. When grabbing the upper packaging box 100 from multiple tightly stacked packaging boxes 100, it can be easily grabbed without lifting the lower packaging box 100 adjacent to it, thereby preventing the position of the lower packaging box 100 from changing, thereby enhancing the safety of the products in the box.

[0113] See also Figure 3In some embodiments, a positioning protrusion 13 is formed at the bottom of the box structure 1 , and the positioning protrusion 13 is arranged in alignment with the opening of the accommodating cavity 11 .

[0114] Among them, the specific structural forms of the positioning protrusion 13 can be various, for example, it can be set as an annular protrusion at the bottom of the box structure 1, or it can be set as a whole protrusion at the bottom of the box structure 1, as long as it is aligned with the opening of the accommodating cavity 11.

[0115] According to the above technical solution, by aligning the positioning protrusion 13 with the opening of the accommodating cavity 11, after the two packaging boxes 100 are stacked, the positioning protrusion 13 of the packaging box 100 on the upper layer will be aligned and inserted into the accommodating cavity 11 of the packaging box 100 on the lower layer, thereby generating a limit along the horizontal direction of the packaging box 100, which can prevent the packaging box 100 on the upper layer from sliding down from a high place, thereby improving the safety of the transportation process.

[0116] In a specific embodiment, the packaging box 100 includes a box structure 1 and a partition structure 2, the box structure 1 forms a accommodating cavity 11, the partition structure 2 is arranged in the accommodating cavity 11, the partition structure 2 includes a plurality of first partition plates 21 and a second partition plate 22 which are vertically arranged in the accommodating cavity 11, the plurality of first partition plates 21 and the plurality of second partition plates 22 are staggeredly connected, and two adjacent first partition plates 21 and two second partition plates 22 are surrounded to form at least a portion of the accommodating groove 111, and the side walls of the accommodating cavity 11 and the corresponding first partition plates 21 and second partition plates 22 are surrounded to form at least a portion of the accommodating groove 111; the first partition plate 21 is formed with a first card groove 211 which is open along its height direction, and a positioning marking portion 25 which is aligned with the first card groove 211, and correspondingly, the second partition plate 22 is formed with a second card groove 221 which is open along its height direction, and a positioning marking portion 25 which is aligned with the second card groove 221, the first partition plate 21 and The second partition plate 22 is connected with the second partition plate 221 by plugging with the first card slot 211. A plurality of first card slots 211 are arranged along the length direction of the first partition plate 21, and a plurality of second card slots 221 are arranged along the length direction of the second partition plate 22. A plurality of second partition plates 22 can be selectively inserted into any first card slot 211 of the first partition plate 21, and a plurality of first partition plates 21 can be selectively inserted into any second card slot 221 of the second partition plate 22. The first partition plate 21 and the second partition plate 22 are respectively provided with mounting holes 23 penetrating in their respective thickness directions corresponding to two adjacent receiving grooves 111. A plurality of mounting holes 23 are arranged along the height direction of the partition structure 2. A snap-fit ​​structure 24 can be selectively arranged in any mounting hole 23.
