[0037] The present utility model will be further described in detail below with reference to the drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the present utility model, rather than limiting the present utility model. In addition, it should be noted that for the convenience of description, only parts related to the present utility model are shown in the drawings, rather than all structures.

[0038] In the description of the present utility model, unless otherwise clearly defined and limited, the terms "connected", "connected", and "fixed" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the internal communication of two components or the interaction relationship between two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0039] In the present utility model, unless otherwise clearly defined and limited, the first feature being "above" or "below" the second feature may include direct contact between the first and second features, or may include that the first and second features are not in direct contact but in contact through other features therebetween. Moreover, the first feature being "above", "above", and "on" the second feature includes the first feature being directly above and obliquely above the second feature, or merely indicating that the first feature has a higher horizontal height than the second feature. The first feature being "below", "below", and "under" the second feature includes the first feature being directly below and obliquely below the second feature, or merely indicating that the first feature has a lower horizontal height than the second feature.

[0040] In the description of this embodiment, the terms "upper," "lower," "right," and other orientations or positional relationships are based on the orientations or positional relationships shown in the accompanying drawings and are intended solely for ease of description and simplified operation. They do not indicate or imply that the devices or components referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on the present invention. Furthermore, the terms "first" and "second" are used solely for descriptive purposes and have no special meaning.

[0041] The technical solution provided by the present invention is described below with reference to the accompanying drawings and specific embodiments.

[0042] This embodiment provides a packaging and transportation device that can package and encapsulate batteries 100 and then transport them to a designated location via a transportation vehicle. This embodiment will use a square aluminum shell battery as an example to specifically illustrate the packaging and transportation device.

[0043] Specifically, combined Figure 1 and Figure 2 As shown, the packaging and transportation device includes a packaging box 1 and multiple pallets 2, wherein the packaging box 1 includes a base 11, a panel 12, and a top cover 13. Multiple pallets 2 are stacked on the base 11. The panel 12 is a box-shaped structure with openings at both ends and is arranged around the periphery of the multiple pallets 2. The bottom opening edge of the panel 12 is sealed to the base 11, and the top cover 13 is abutted against the top opening of the panel 12 to form a packaging cavity within the packaging box 1 that can seal and enclose the batteries 100. Multiple trays 2 are stacked vertically in the packaging cavity. The trays 2 are provided with multiple spaced mounting slots 20. The mounting slots 20 are square in shape to match the cross-sectional shape of the batteries 100, and the batteries 100 can be limitedly accommodated within the mounting slots 20.

[0044] In the above arrangement, by housing multiple batteries 100 within separate mounting slots 20, batteries 100 in adjacent mounting slots 20 are prevented from contact, resulting in damage and deformation. Furthermore, the bottom plates of the mounting slots 20 also support and separate the batteries 100 on adjacent trays 2, thereby preventing vertical contact and collision between adjacent batteries 100. Furthermore, the packaging box 1 encapsulates the batteries 100 on all sides, eliminating the risk of direct contact with the external environment and preventing oxidation during transportation, ensuring that the batteries 100 can be subsequently welded in groups.

[0045] In this embodiment, the enclosure 12 is made of plastic pallets to form external protection for the battery 100. Compared with the existing combination of wooden pallets + paper packaging boxes, it has higher strength, better waterproof and moisture-proof properties, is not easy to shed, and has a longer service life.

[0046] Specifically, in this embodiment, in combination with Figures 3 to 8 As shown, the terminal post 110 is installed on the upper surface of the battery 100. The battery 100 is inserted into the installation groove 20 in a standing posture. The installation groove 20 includes a first groove body 201 and a second groove body 202. Among two adjacent trays 2, the bottom surface of the upper tray 2 is provided with the first groove body 201, and the top surface of the lower tray 2 is provided with the second groove body 202. The first groove body 201 surrounds at least part of the top of the battery 100, and the second groove body 202 surrounds at least part of the bottom of the battery 100, so as to complete the clamping of the battery 100 by the way of buckling the two trays 2. After removing the upper tray 2, the battery 100 inserted on the lower tray 2 can be exposed, so as to facilitate the clamping of the battery 100.

[0047] It should be noted that, in this embodiment, the inner wall surface of the installation groove 20 has an avoidance hole 2011. After the battery 100 is placed in the installation groove 20, the avoidance hole 2011 can avoid the convex structure protruding from the outer surface of the battery 100, so as to prevent the tray 2 from directly contacting the convex structure, ensure the integrity of the convex structure, and prevent it from being squeezed and damaged by the tray 2.

[0048] Specifically, in this embodiment, the convex structure includes a terminal post 110 and an explosion-proof valve (not shown in the figure). The terminal post 110 (including a positive terminal post and a negative terminal post) protrudes from the outer surface of the battery 100, and the explosion-proof valve is located at the center of the top cover 13 of the battery 100. In addition, the avoidance hole 2011 includes a first clearance hole 20111 and a second clearance hole 20112. The first clearance hole 20111 and the second clearance hole 20112 are provided on the inner wall surface of the first groove body 201. The first clearance hole 20111 is used to avoid the terminal post 110, and the second clearance hole 20112 is used to avoid the explosion-proof valve. Through the above settings, after the battery 100 is placed in the installation groove 20 in a standing posture, the terminal post 110 and the explosion-proof valve will not directly contact the tray 2, so as to prevent the tray 2 from squeezing and knocking the terminal post 110 and the explosion-proof valve during bumpy transportation, and keep the shape and function of the terminal post 110 and the explosion-proof valve intact.

[0049] It can be understood that, in this embodiment, two first clearance holes 20111 are provided on the first groove body 201 to avoid the positive terminal post and the negative terminal post respectively, and the cross-sectional shape of the first clearance hole 20111 is the same as that of the positive terminal post and the negative terminal post, both of which are square.

[0050] More specifically, the avoidance hole 2011 further includes a third clearance hole 20113. The four corner positions of the installation groove 20 are recessed inward to form the third clearance hole 20113. The third clearance holes 20113 are oppositely arranged at the edges of the battery 100, so as to prevent hard contact between the edges of the metal shell of the battery 100 and the inner wall surface of the installation groove 20, thereby reducing the possibility of the metal shell of the battery 100 being damaged and deformed.

[0051] Further, in this embodiment, referring to Figure 5 As shown, an exhaust groove 20114 is provided on the inner side wall of the first groove body 201. The size of the first clearance hole 20111 needs to be opened to communicate with the exhaust groove 20114, and the size of the second clearance hole 20112 needs to be opened to communicate with the third clearance hole 20113. In this way, the gas generated during the charging and discharging process of the battery 100 will be released into the pole post clearance hole 20112 through the pole post 110, and then released to the outside from the pole post clearance hole 20112 through the third clearance hole 20113, so that the pole post 110 maintains air permeability; in addition, when the internal pressure of the battery 100 surges, causing the explosion-proof valve to rupture, the gas ejected from the explosion-proof valve can be discharged to the outside through the explosion-proof valve clearance hole 20111 and the exhaust groove 20114 in sequence, thereby avoiding the accumulation of gas between the battery 100 and the first groove body 201, and contributing to maintaining the stable safety inside the battery 100.

[0052] It should be noted that in some other parallel embodiments, for example, when the packaging and transportation device is used to transport cylindrical batteries, the opening of the third clearance hole 20113 can be omitted, so that only the exhaust groove 20114 is provided on the side wall of the first groove body 201, and the gas generated in the battery 100 can be discharged from the installation groove 20; or, in order to reduce the mold opening difficulty and improve the production efficiency of the tray 2, the opening of the exhaust groove 20114 can also be omitted, and only the third clearance hole 20113 is communicated with the second clearance hole 20112, which can also achieve the effect of discharging the gas generated in the battery 100 from the installation groove 20. Therefore, those skilled in the art can make a choice according to the actual situation, and the present invention does not limit this.

[0053] It should be added that in this embodiment, referring to Figure 8As shown, a first ventilation groove 2021 is formed at the bottom of the second tank body 202, and a second ventilation groove 2022 is formed on the inner side wall of the first tank body 201. The second ventilation groove 2022 communicates with the first ventilation groove 2021, so that the gas discharged from the weak bottom of the battery 100 housing can be discharged from the second tank body 202 through the second ventilation groove 2022 and the first ventilation groove 2021. Thus, it can effectively prevent the gas generated inside the battery 100 from accumulating at the bottom of the battery 100, and further improve the safety and reliability of the battery 100 during transportation. Preferably, the second ventilation groove 2022 is in the shape of a cross-shaped groove, so that there are channels for discharging gas from the second ventilation groove 2022 around the four sides of the bottom of the battery 100, thereby further reducing the possibility of gas accumulation at the bottom of the battery 100.

[0054] As Figure 8 shown, the installation groove 20 further includes a receiving groove 203. In this embodiment, the receiving groove 203 is arranged on the blocking portion 204 for separating the two second tank bodies 202. The receiving groove 203 communicates with the second tank body 202, and a drying medium, such as silica gel, activated carbon, etc., is installed in the receiving groove 203. The drying medium can absorb the water vapor emitted from the installation groove 20, thereby keeping the packaging cavity dry and preventing the battery 100 from short-circuiting. Preferably, in this embodiment, a receiving groove 203 is respectively arranged at the four corner positions of the tray 2 to meet the requirements for the dryness degree of the packaging cavity under actual working conditions.

[0055] Specifically, in this embodiment, the tray 2 includes a bottom tray 21, a middle tray 22 and a top tray 23. The bottom tray 21 is fitted and abutted against the bottom of the packaging box 1. A plurality of middle trays 22 are arranged and clamped between the bottom tray 21 and the top tray 23. The top tray 23 is clamped between the top of the packaging box 1 and the middle tray 22 to space the battery 100 and the top of the packaging box 1 to prevent direct contact between the two. The bottom tray 21, the middle tray 22 and the top tray 23 are all made of recyclable EPP foam plastics. Compared with EPO materials, the tray 2 made of EPP materials has better shock-absorbing and energy-absorbing performance, higher recovery rate after deformation, better heat resistance, chemical resistance, oil resistance and heat insulation, and is light in weight, which can greatly reduce the weight of the overall structure.

[0056] Among them, in combination with Figure 2 、 Figure 9As shown in the figure, a plurality of limiting blocks 21a are provided at the bottom of the bottom tray 21, and a plurality of limiting grooves 111 are provided on the base 11. The limiting grooves 111 are arranged in one-to-one correspondence with the limiting blocks 21a. After the bottom tray 21 is placed on the base 11, the limiting blocks 21a are inserted into the limiting grooves 111 one by one, thereby restricting the horizontal movement of the bottom tray 21, so that during the subsequent stacking of the trays 22, the top tray 23 and the transportation process, the bottom tray 21 and the base 11 can remain relatively stable, avoiding the shaking of the bottom tray 21, and further improving the stacking accuracy of the trays 2 and the stability during the transportation of the battery 100. Moreover, a second groove 202 and a receiving groove 203 are provided at the top of the bottom tray 21.

[0057] Four middle trays 22 are selected. The four middle trays 22 are stacked on the top of the bottom tray 21 in sequence. A first groove 201 is provided on the lower surface of the middle tray 22, and a second groove 202 is provided on the upper surface, so as to be opposite to the second groove 202 and the first groove 201 on the adjacent tray 2 respectively and can be buckled to form an installation groove 20. In this embodiment, a receiving groove 203 is also provided on the upper surface of the middle tray 22.

[0058] A first groove 201 is formed at the bottom of the top tray 23, and it can be buckled with the second groove 202 on the uppermost middle tray 22 to form an installation groove 20.

[0059] Furthermore, in this embodiment, positioning structures 24 are provided on the bottom tray 21, the middle trays 22 and the fixed tray 23. Refer to Figure 8 As shown in the figure, taking the bottom tray 21 as an example, four MARK positioning holes are evenly arranged circumferentially around the center of the bottom tray 21. After the bottom tray 21 is installed on the base 11, an external positioning device (such as a CCD vision positioning camera) can detect the actual positions of the four MARK positioning holes, calculate the offset amount, obtain the offset signals of each MARK positioning hole, and then the CCD vision positioning camera feeds back the offset signal to the corresponding rectifying device, and the rectifying device rectifies the direction and angle of the bottom tray 21, so that the bottom tray 21 can be moved to make the four MARK positioning holes located at the preset positions pre-stored by the CCD vision positioning camera, so as to accurately place the bottom tray 21 in the standard area at the bottom of the packaging box 1. It can be understood that the positioning processes of the middle trays 22 and the top tray 23 are similar to that of the bottom tray 21, and the present invention will not elaborate here too much.

[0060] It should be noted that the above process of loading and unloading the bottom tray 21, the middle tray 22, and the top tray 23 can be fully automatically completed by a mechanical gripper. A CCD vision positioning camera is assembled on the fixed end of the mechanical gripper. During the process of loading the bottom tray 21, the middle tray 22, and the top tray 23 onto the base 11 respectively through the clamping part of the mechanical gripper, the CCD vision positioning camera and the deviation correction device can be used to detect and correct the deviation of the loading position, so as to achieve accurate loading of the bottom tray 21, the middle tray 22, and the top tray 23.

[0061] Furthermore, in this embodiment, along the direction from the bottom of the tray 2 to the top of the tray 2, clamping grooves 25 are also provided on the side walls of the middle tray 22 and the top tray 23. The clamping part of the mechanical gripper can be clamped in the clamping grooves 25 to improve the clamping stability of the mechanical gripper. Of course, it can be understood that in other embodiments, clamping grooves 25 can also be provided on the side wall of the bottom tray 21.

[0062] Reference Figure 8 As shown, in this embodiment, a chamfer 2023 is provided along the circumferential direction at the opening of the second groove body 202. The chamfer 2023 can play a guiding role for the clamping part of the mechanical gripper, so that the clamping part can extend into the second groove body 202 along the chamfer 2023 and accurately clamp the battery 100 in the second groove body 202, facilitating the unloading of the battery 100.

[0063] Reference Figure 2 As shown, in this embodiment, first anti-fooling parts 26 are provided at the ends of the bottom tray 21, the middle tray 22, and the top tray 23, and a second anti-fooling part 121 is provided on the surrounding plate. When the surrounding plate is assembled with the bottom plate, the surrounding plate can be accurately sleeved on the outer periphery of the bottom tray 21, the middle tray 22, and the top tray 23 by means of the limit cooperation between the first anti-fooling part 26 and the second anti-fooling part 121, thereby improving the accuracy and efficiency of installing the surrounding plate.

[0064] Specifically, in this embodiment, the bottom tray 21, the middle tray 22, and the top tray 23 are all square plate members. Taking the bottom tray 21 as an example, reference Figure 6 、 Figure 7 As shown, the first anti-fooling part 26 is at least one first cut corner among multiple corners of the bottom tray 21, and the second anti-fooling part 121 is at least one second cut corner on the surrounding plate 12 corresponding to the first anti-fooling part 26. In this way, anti-fooling is achieved by means of cut corners, which can simplify the structures of the first anti-fooling part 26 and the second anti-fooling part 121, and will not prevent the battery 100 from being placed in the installation groove 20. It can also improve the recognition effect and contribute to the installation positioning of the surrounding plate 12.

[0065] More specifically, the first chamfer includes a first bevel chamfer 261 and a first rounded chamfer 262. At least one corner of the bottom tray 21 is provided with the first bevel chamfer 261, and at least one of the remaining corners on the bottom tray 21 is provided with the first rounded chamfer 262. For example, in this embodiment, both ends of one side of the bottom tray 21 are provided with the first bevel chamfer 261, and both ends of the other opposite side of the bottom tray 21 are provided with the first rounded chamfer 262, thereby increasing the aesthetic appearance of the bottom tray 21.

[0066] Of course, it can be understood that in other embodiments, only one first bevel chamfer 261 and one first rounded chamfer 262 can also be provided on the bottom tray 21; one first bevel chamfer 261, two or three first rounded chamfers 262 can also be provided on the bottom tray 21; one first rounded chamfer 262, two or three first bevel chamfers 261 can also be provided on the bottom tray 21. All of these are helpful to improve the aesthetic appearance of the bottom tray 21, and can eliminate the sharp corners of the bottom tray 21, enhancing the safety of the bottom tray. Therefore, they all fall within the protection scope of the present utility model.

[0067] It should be noted that the outer shapes of the middle tray 22 and the top tray 23 are the same as that of the bottom tray 21, so the first anti-fooling part 26 on the middle tray 22 and the top tray 23 will not be elaborated herein.

[0068] More specifically, the second chamfer includes a second bevel chamfer 1211. In this embodiment, as shown in Figure 7 the enclosure panel includes four second bevel chamfers 1211. Since the cross-sectional area of the enclosure panel 12 is larger than that of the tray 2, only two of the second bevel chamfers 1211 need to cooperate with the two first bevel chamfers 261 to achieve the positioning and assembly of the enclosure panel 12, and the part of the tray 2 provided with two first rounded chamfers 262 will not hinder the installation of the enclosure panel 12. Through the above settings, while ensuring that the enclosure panel 12 can be installed in place, the structure of the enclosure panel 12 can be simplified, thereby reducing the production cost and pressure of the enclosure panel 12.

[0069] It should be noted that in other embodiments, the second chamfer may also include a second rounded chamfer. The enclosure panel 12 includes two second bevel chamfers 1211 and two second rounded chamfers to respectively correspond to the two first bevel chamfers 261 and the two first rounded chamfers 262, so that the cross-sectional shape of the enclosure panel 12 is adapted to the cross-sectional shape of the tray 2, thereby making the cooperation between the two more closely and firmly. Therefore, both of the above two structural forms of the enclosure panel 12 can meet the requirements of the accurate assembly of the enclosure panel 12 and the tray 2. Those skilled in the art can choose one of the ways to produce and manufacture the enclosure panel 12 according to actual needs, and the present utility model does not limit this.

[0070] In the description of this specification, the descriptions referring to terms such as "some embodiments" and "other embodiments" mean that the specific features, structures, materials, or characteristics described in connection with the embodiment or example are included in at least one embodiment or example of the present utility model. In this specification, the schematic representations of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials, or characteristics described can be combined in a suitable manner in any one or more embodiments or examples.

[0071] Obviously, the above embodiments of the present utility model are merely examples given for clearly illustrating the present utility model, rather than limitations on the implementation manners of the present utility model.
