Description

Pallets, battery processing equipment and battery production lines Technical Field

[0001] The present application relates to the field of battery technology, and in particular to a pallet, battery processing equipment and a battery production line. Background Art

[0002] During the processing of batteries, it is usually necessary to constrain the batteries to a tray so that the batteries can be moved through the tray.

[0003] In some cases, the tray has low compatibility and can generally only accommodate a single type of battery, making it difficult to accommodate other types of batteries.

[0004] Summary of the Invention

[0005] In view of the above problems, embodiments of the present application provide a pallet, battery processing equipment, and a battery production line, which can improve the problem of low compatibility of the pallet.

[0006] The technical solution adopted in the embodiment of this application is:

[0007] In a first aspect, an embodiment of the present application provides a tray, comprising:

[0008] Bottom bracket;

[0009] The limiting structure is arranged on the bottom support and encloses a plurality of limiting spaces; the limiting spaces are located on the side of the bottom support along the first direction and are used to limit the batteries; the projections of the plurality of limiting spaces along the first direction are different.

[0010] The tray provided in the embodiment of the present application is surrounded by a limiting structure to form multiple limiting spaces located on the side of the bottom support member along the first direction, and the projections of the multiple limiting spaces along the first direction are different, so that the multiple limiting spaces can be used to respectively limit multiple different types of batteries, that is, the tray can be suitable for multiple different types of batteries, thereby improving the compatibility and versatility of the tray.

[0011] In some embodiments, at least part of the limiting spaces are located on the same side of the bottom supporting member along the first direction, and their projections along the first direction are partially overlapped.

[0012] In this way, the limiting structure can be used to selectively limit the corresponding type of battery through the corresponding limiting space. In addition, the limiting structure has a smaller size in the direction perpendicular to the first direction, so that the size of the tray can be reduced.

[0013] In some embodiments, the plurality of limiting spaces are arranged in sequence and connected along the first direction.

[0014] This arrangement makes the distribution of the multiple limiting spaces on the limiting structure very clear, making it easier to place batteries in the limiting spaces of corresponding models, thereby improving the efficiency of the tray's battery limiting function. In addition, the limiting structure is very simple.

[0015] In some embodiments, on a cross section parallel to the first direction, at least two limiting spaces are partially overlapped.

[0016] Such an arrangement can reduce the size of the tray in the first direction, thereby facilitating a miniaturized design of the tray.

[0017] In some embodiments, the two limiting spaces are respectively a first limiting space and a second limiting space; in the second direction, a size of the first limiting space is smaller than a size of the second limiting space; and the second direction intersects with the first direction.

[0018] In this way, the battery constrained by the first limiting space and the battery constrained by the second limiting space have different sizes along the second direction, that is, the limiting structure can be used to constrain batteries with different sizes along the second direction.

[0019] In some embodiments, in the third direction, the size of the first limiting space is smaller than that of the second limiting space; the third direction intersects with the first direction and the second direction respectively, and the first direction, the second direction and the third direction are not located in the same plane at the same time.

[0020] With such an arrangement, the limiting structure can be used to limit batteries having different sizes along the second direction and the third direction.

[0021] In some embodiments, the limiting structure includes at least one group of limiting components, the limiting components including a first limiting component and a second limiting component spaced apart on the bottom support member along the second direction and a third limiting component and a fourth limiting component spaced apart on the bottom support member along the third direction, the first limiting component, the second limiting component, the third limiting component and the fourth limiting component constitute a plurality of limiting spaces; the first direction intersects with the second direction, the first direction intersects with the third direction, and the second direction intersects with the third direction, and the first direction, the second direction and the third direction are not located in the same plane at the same time.

[0022] By providing the first limiting member, the second limiting member, the third limiting member and the fourth limiting member, the limiting assembly forms a plurality of limiting spaces, so that the tray can be suitable for batteries of various models, thereby improving the compatibility and versatility of the tray.

[0023] In some embodiments, the first limiting member includes a plurality of first blocks distributed in sequence along the second direction, and in the direction of the first block away from the second limiting member along the second direction, the sizes of the plurality of first blocks along the first direction are gradually increased; each first block is used to form a limiting space with the second limiting member, and the limiting spaces corresponding to the plurality of first blocks are respectively connected and arranged in sequence along the first direction.

[0024] In this way, the multiple limiting spaces defined by the first limiting member and the second limiting member can be used to respectively limit batteries of different sizes along the second direction, and the operation of placing the batteries into the limiting spaces is also facilitated.

[0025] In some embodiments, the plurality of first blocks are spaced apart along the second direction; or, the plurality of first blocks are sequentially connected along the second direction to form a stepped structure.

[0026] Such an arrangement can reduce the size of the first position-limiting member in the second direction. Alternatively, the plurality of first sub-blocks of the first position-limiting member can be arranged separately, thereby making the arrangement of the first position-limiting member more flexible.

[0027] In some embodiments, the second limiting member includes a plurality of second blocks distributed in sequence along the second direction. In the direction in which the second blocks are away from the first block along the second direction, the sizes of the plurality of second blocks along the first direction are gradually increased, and each second block is used to form a limiting space with the corresponding first block.

[0028] This arrangement allows for the corresponding arrangement of multiple first sub-blocks with multiple second sub-blocks, facilitating the formation of multiple confined spaces that are sequentially connected along the first direction. Furthermore, the multiple confined spaces have different sizes along the second direction to accommodate batteries of varying sizes along the second direction. Furthermore, this facilitates the placement of batteries into the confined spaces.

[0029] In some embodiments, the plurality of second blocks are spaced apart along the second direction; or, the plurality of second blocks are sequentially connected along the second direction to form a stepped structure.

[0030] Such an arrangement can reduce the size of the second position-limiting member along the second direction. Alternatively, the plurality of second sub-blocks of the second position-limiting member can be arranged separately, thereby making the arrangement of the second position-limiting member more flexible.

[0031] In some embodiments, the third limiting member includes a plurality of third blocks distributed in sequence along the third direction, and in the direction of the third blocks away from the fourth limiting member along the third direction, the sizes of the plurality of third blocks along the first direction are gradually increased; each third block is used to form a limiting space with the fourth limiting member, and the limiting spaces corresponding to the plurality of third blocks are respectively connected and arranged in sequence along the first direction.

[0032] In this way, the plurality of limiting spaces defined by the third limiting member and the fourth limiting member can be used to respectively limit batteries of different sizes along the third direction, and also facilitate the operation of placing the batteries into the limiting spaces.

[0033] In some embodiments, the plurality of third blocks are spaced apart along the third direction; or, the plurality of third blocks are sequentially connected along the third direction to form a step structure.

[0034] Such an arrangement can reduce the size of the third limiting member in the third direction. Alternatively, the plurality of third sub-blocks of the third limiting member can be arranged separately, thereby making the arrangement of the third limiting member more flexible.

[0035] In some embodiments, the fourth limiting member includes a plurality of fourth blocks distributed in sequence along the third direction. In the direction of the fourth block away from the third block along the third direction, the sizes of the plurality of fourth blocks along the first direction are gradually increased, and each fourth block is used to form a limiting space with the corresponding third block.

[0036] This arrangement allows the corresponding arrangement of the plurality of third sub-blocks with the plurality of fourth sub-blocks, thereby forming a plurality of confined spaces that are sequentially connected along the first direction. Furthermore, the plurality of confined spaces have different sizes along the third direction to accommodate batteries of varying sizes along the third direction. Furthermore, this facilitates the placement of batteries into the confined spaces.

[0037] In some embodiments, the plurality of fourth blocks are spaced apart along the third direction; or, the plurality of fourth blocks are sequentially connected along the third direction to form a step structure.

[0038] Such an arrangement can reduce the size of the fourth position-limiting member in the third direction. Alternatively, the plurality of fourth sub-blocks of the fourth position-limiting member can be arranged separately, thereby making the arrangement of the fourth position-limiting member more flexible.

[0039] In some embodiments, at least one limiting space is formed by a first block, a second limiting member, a third block, and a fourth limiting member.

[0040] By adopting the above technical solution, at least one limiting space can limit the battery along the second direction and the third direction respectively.

[0041] In some embodiments, each first block, each third block, the second limiting member, and the fourth limiting member form each limiting space.

[0042] Such an arrangement enables the limiting structure to be used to adapt to batteries of different models with different sizes along the second direction and the third direction, so that the tray has very high compatibility and versatility.

[0043] In some embodiments, a plurality of first blocks respectively form a limited space with the same third block.

[0044] With this arrangement, the multiple limiting spaces formed by the limiting structure can be used to adapt to batteries of different models with different sizes along the second direction, and can also be used to adapt to batteries of different models with different sizes along the third direction, so that the tray has very high compatibility and versatility.

[0045] In some embodiments, at least one confined space corresponding to the first block and any confined space corresponding to the third block are different confined spaces.

[0046] Such an arrangement enables at least one first block and a third block to respectively define different limiting spaces, that is, the limiting space corresponding to at least one first block and the limiting space defined by the third block are different limiting spaces. In this way, the limiting structure can define a variety of different limiting spaces and can be compatible with more types of batteries.

[0047] In some embodiments, the limiting assembly also includes a fifth limiting member arranged between the first block and the third block and a sixth limiting member arranged between the second limiting member and the fourth limiting member; the fifth limiting member and the fourth limiting member are used to form a limiting space with the first block and the second limiting member, and are also used to form a limiting space with the third block and the fourth limiting member.

[0048] By adopting the above technical solution, the limiting space corresponding to one of the first blocks and the limiting space corresponding to any third block can limit the battery in the second direction and the third direction to maintain the limiting stability of the battery.

[0049] In some embodiments, the limiting structure further includes a support member disposed on the bottom supporting member, and the support member is used to support the workpiece along the first direction.

[0050] Such an arrangement enables the support member to support the battery along the first direction to maintain the positional stability of the battery on the tray.

[0051] In some embodiments, the first limiting member, the second limiting member, the third limiting member, and the fourth limiting member are sequentially connected around the first direction;

[0052] Alternatively, the first limiting member is connected to the third limiting member and / or the second limiting member is connected to the fourth limiting member.

[0053] Such arrangement makes the limiting structure substantially annular in structure. Alternatively, the limiting structure can better avoid the handling device used to carry the batteries, thereby facilitating the positioning of the batteries on the tray.

[0054] In some embodiments, a avoidance groove is provided on one side of the first limiting member along the second direction toward the second limiting member, or one side of the second limiting member along the second direction toward the first limiting member, or one side of the third limiting member along the third direction toward the fourth limiting member, or one side of the fourth limiting member along the third direction toward the third limiting member.

[0055] With such arrangement, when at least a portion of the battery is confined in the avoidance groove, the battery pole or other components can be avoided in the avoidance groove.

[0056] In some embodiments, the limiting structure is a soft material and / or an elastic material.

[0057] This configuration can improve the problem of battery damage.

[0058] In a second aspect, an embodiment of the present application provides a battery processing device, including a tray.

[0059] The battery processing equipment provided in the embodiment of the present application also has the advantage of being compatible with a variety of different models of batteries by adopting the above-mentioned tray.

[0060] In a third aspect, an embodiment of the present application provides a battery production line, including battery processing equipment.

[0061] The battery production line provided in the embodiment of the present application also has the advantage of being compatible with a variety of different models of batteries by adopting the battery processing equipment involved above.

DETAILED DESCRIPTION

[0083] The following describes in detail embodiments of the present application, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limiting the present application.

[0084] In the description of this application, it should be understood that the terms "length", "width", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on this application.

[0085] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be understood to indicate or imply relative importance or to implicitly indicate the quantity of the technical features indicated. Thus, a feature specified as "first" or "second" may explicitly or implicitly include one or more of the features.

[0086] In the description of this application, "a plurality of" means more than two, and unless otherwise specifically defined, "more than two" includes two. Accordingly, "a plurality of groups" means more than two groups, including two groups.

[0087] In the description of this application, unless otherwise expressly specified or limited, terms such as "installed," "connected," "connect," and "fixed" should be understood in a broad sense. For example, they may refer to fixed connections, detachable connections, or integration; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and they may refer to internal communication between two components or interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in this application based on specific circumstances.

For example, A and / or B can mean: A exists, A and B exist at the same time, and B exists. In addition, in this application, the character " / " generally indicates that the related objects are in an "or" relationship.

[0089] Although the present application has been described with reference to preferred embodiments, various modifications may be made thereto and components may be substituted with equivalents without departing from the scope of the present application. In particular, the various technical features described in the various embodiments may be combined in any manner as long as there are no structural conflicts. The present application is not limited to the specific embodiments disclosed herein, but encompasses all technical solutions within the scope of the claims.

[0090] During the battery processing, it is usually necessary to limit the batteries to a pallet and move the batteries through the pallet so that the batteries can be transferred to the corresponding workstation for inspection, gluing and other operations.

[0091] The tray includes a bottom supporting member and a limiting structure provided on the bottom supporting member. The limiting structure defines a limiting space, and the limiting space is used to accommodate and limit the battery.

[0092] In some cases, the compatibility of the tray is low, and it can generally only limit the position of a single type of battery, and it is difficult to take into account other types of batteries. Taking the square battery as an example, the battery has thickness direction, length direction and width direction. When the battery is limited to the tray, one side of the battery along the thickness direction can face the bottom support member, that is, the limiting space can be located on the side of the bottom support member in the thickness direction of the battery. And, at this time, the battery is limited to the limiting space along the length direction and width direction respectively. It should be noted here that the limiting space has predetermined dimensions in the length direction and width direction of the battery, respectively, so that batteries of corresponding models can be accommodated and limited in the limiting space. When the battery models are different, the length and / or width of the battery will be different, so that the battery cannot be adaptively accommodated in the limiting space, that is, the tray cannot adaptively limit the battery of that model.

[0093] In this way, when it is necessary to limit or operate other types of batteries, the pallet needs to be remodeled or replaced with a pallet of the corresponding model so that the pallet can be suitable for the corresponding type of battery. This will inevitably lead to problems such as cumbersome battery processing operations, low efficiency, and high costs.

[0094] Based on the above considerations, an embodiment of the present application provides a pallet, battery processing equipment and a battery production line, which are surrounded by a limiting structure to form multiple limiting spaces located on the side of the bottom support along the first direction, and the projections of the multiple limiting spaces along the first direction are different, so that the multiple limiting spaces can be used to respectively limit multiple different types of batteries, that is, the pallet can be suitable for multiple different types of batteries, thereby improving the compatibility and versatility of the pallet.

[0095] The batteries involved in the embodiments of the present application may be battery cells or a single physical module comprising one or more battery cells to provide higher voltage and capacity. A battery cell is the smallest unit that stores and outputs electrical energy. When there are multiple battery cells, the multiple battery cells may be connected in series, in parallel, or in a hybrid configuration via a busbar. A hybrid configuration refers to multiple battery cells being connected in both series and parallel configurations.

[0096] While the trays involved in the embodiments of this application were developed to address the issue of poor compatibility between trays and batteries that arises during battery processing, their application is not limited to this and can be applied to any situation requiring position limiting. It is understood that the trays involved in the embodiments of this application can be used to position batteries, as well as other workpieces besides batteries.

[0097] For ease of description, the embodiments of the present application are mainly described by taking the tray for limiting the position of batteries as an example. The same explanation can be given for the situation where the tray limits the position of other workpieces, and they will not be listed one by one.

[0098] It should be added here that the pallet is used to limit the batteries, can be used to transport batteries, and can also be used for operations such as gluing and testing the batteries on the pallet.

[0099] Please refer to FIG. 1 , which shows a battery processing device 1000 provided in some embodiments of the present application. The battery processing device 1000 includes a tray 100 .

[0100] As an example, as shown in FIG1 , the battery processing equipment 1000 may include a gluing device 200 for gluing batteries. The tray 100 may be used to limit the position of the batteries and transfer the batteries to the gluing station of the gluing device 200 for gluing the batteries.

[0101] As an example, the battery processing equipment 1000 may include a detection device for performing detection operations on batteries. The tray 100 may be used to limit the position of the batteries and transport the batteries to the detection station of the detection device for battery detection operations.

[0102] As an example, the battery processing equipment 1000 may also include a stacking device for stacking battery cells to form a battery. The tray 100 can be used to limit the battery cells and transfer the battery cells to the stacking station of the stacking device to allow the battery cells to be stacked to form a battery.

[0103] Please refer to Figures 2 to 5 together. Figure 2 is a three-dimensional schematic diagram of the tray 100 provided in some embodiments of the present application, Figure 3 is a partial schematic diagram of Figure 2, Figure 4 is a cross-sectional view of Figure 3 along AA, and Figure 5 is a top view of Figure 3, that is, Figure 5 is a schematic diagram of Figure 3 along the first direction Z. The tray 100 provided in the embodiment of the present application includes a bottom support member 10 and a limiting structure 20. The limiting structure 20 is arranged on the bottom support member 10 and encloses a plurality of limiting spaces 201. The limiting space 201 is located on the side of the bottom support member 10 along the first direction Z and is used to limit the battery. The projections of the plurality of limiting spaces 201 along the first direction Z are different.

[0104] The bottom supporting member 10 refers to the bottom supporting portion of the tray 100, and is mainly used for installing the limiting structure 20. The bottom supporting member 10 can be a plate-shaped structure or a structure of other shapes.

[0105] The first direction Z refers to the direction in which the tray 100 can be used to receive batteries. For example, when the bottom support member 10 is a plate-shaped structure, the first direction Z can be the thickness direction of the bottom support member 10 .

[0106] The limiting structure 20 is a component used to limit the position of the battery. Specifically, the limiting structure 20 forms a limiting space 201. At least part of the battery can be located in the limiting space 201. The battery is limited in the limiting space 201 by the inner sidewall of the limiting space 201.

[0107] In some possible designs, at least a portion of the limiting structure 20 may be located on opposite sides of the limiting space 201 along the second direction Y to define the size of the limiting space 201 along the second direction Y, thereby limiting the battery in the second direction Y. In other possible designs, at least a portion of the limiting structure 20 may also be located on opposite sides of the limiting space 201 along the third direction X to define the size of the limiting space 201 in the third direction X, thereby limiting the battery in the third direction X. In some other possible designs, as shown in Figures 2 to 5, the limiting structure 20 can also be configured so that a portion of it is arranged on opposite sides of the limiting space 201 along the second direction Y to limit the size of the limiting space 201 along the second direction Y, such as the first limiting member 211 and the second limiting member 212 mentioned below, and the other portion is arranged on opposite sides of the limiting space 201 along the third direction X to limit the size of the limiting space 201 along the third direction X, thereby realizing the limitation of the battery in the second direction Y and the third direction X, such as the third limiting member 213 and the fourth limiting member 214 mentioned below.

[0108] In the case where at least a portion of the battery is confined within the confined space 201, the battery may be completely contained within the corresponding confined space 201, or may be only partially contained within the corresponding confined space 201. In the case where the battery is only partially contained within the corresponding confined space 201, another portion of the battery may be located within another confined space 201 or outside the confined space 201, but the battery is still confined by the corresponding confined space 201.

[0109] As shown in Figures 2 to 4 , at least a portion of the limiting structure 20 is disposed laterally of the bottom supporting member 10 along the first direction Z. Thus, the limiting space 201 formed by the limiting structure 20 can be located laterally of the bottom supporting member 10 along the first direction Z.

[0110] The limiting space 201 is located on the side of the bottom support member 10 along the first direction Z. Multiple limiting spaces 201 can be located on the same side of the bottom support member 10 along the first direction Z, as shown in Figures 2 to 4; or multiple limiting spaces 201 can be arranged on opposite sides of the bottom support member 10 along the first direction Z.

[0111] In some possible designs, the projections of multiple confined spaces 201 projected onto the bottom support member 10 along the first direction Z can be partially overlapped, as shown in Figure 5. Figure 5 is a top view of the tray 100, which is a viewing angle along the first direction Z, the same as the viewing angle of the projections of multiple confined spaces 201 projected onto the bottom support member 10 along the first direction Z. Alternatively, in other possible designs, the projections of multiple confined spaces 201 projected onto the bottom support member 10 along the first direction Z can be staggered, for example, they can be staggered along the second direction Y or the third direction X, or they can be staggered along directions that intersect the first direction Z, the second direction Y and the third direction X respectively. Alternatively, in some other possible designs, among the multiple confined spaces 201, the projections of some confined spaces 201 projected onto the bottom support member 10 along the first direction Z are overlapped, and the projections of some confined spaces 201 projected onto the bottom support member 10 along the first direction Z are staggered.

[0112] The projections of the multiple limiting spaces 201 along the first direction Z are different, which means that among any two limiting spaces 201, the projection of one limiting space 201 along the first direction Z onto the bottom support member 10 is different from the projection of the other limiting space 201 along the first direction Z onto the bottom support member 10. The different projections can be different in size along the second direction Y or in size along the third direction X. Based on this, each limiting space 201 can be used to adaptively limit the corresponding model of battery.

[0113] As an example, as shown in Figures 4 and 5, the limiting structure 20 encloses two limiting spaces 201, namely a first limiting space 201a and a second limiting space 201b. In Figures 4 and 5, the first limiting space 201a and the second limiting space 201b are demarcated by dotted lines. The dimension of the first limiting space 201a along the second direction Y is smaller than the dimension of the second limiting space 201b along the second direction Y, so that the first limiting space 201a and the second limiting space 201b are different.

[0114] As an example, as shown in Figures 6 to 8, Figure 6 is a partial structural diagram of the tray 100 provided in other embodiments of the present application, Figure 7 is a cross-sectional view along BB in Figure 6, and Figure 8 is a cross-sectional view along CC in Figure 6. The two limiting spaces 201 formed by the limiting structure 20 are respectively the first limiting space 201a and the second limiting space 201b. In Figures 7 and 8, the first limiting space 201a and the second limiting space 201b are divided by dotted lines. The size of the first limiting space 201a along the second direction Y is smaller than the size of the second limiting space 201b along the second direction Y, and the size of the first limiting space 201a along the third direction X is smaller than the size of the second limiting space 201b along the third direction X, so that the first limiting space 201a and the second limiting space 201b are different.

[0115] It should also be noted that the multiple limiting spaces 201 formed by the limiting structure 20 can be used to limit batteries of corresponding models at the same time, or can be used to limit batteries of corresponding models selectively.

[0116] The first direction Z and the second direction Y intersect, the first direction Z and the third direction X intersect, the second direction Y intersects, and the first direction Z, the second direction Y and the third direction X do not all lie in the same plane at the same time. The intersection of the first direction Z and the second direction Y means that the first direction Z and the second direction Y are not parallel, that is, the first direction Z and the second direction Y form an angle greater than 0° and less than 180°. The first direction Z and the second direction Y may be perpendicular to each other or not. The first direction Z and the second direction Y may be directions intersecting on the same plane; or they may be directions on different planes, and the projection of the first direction Z on the plane where the second direction Y lies may intersect with the second direction Y. The intersection of the first direction Z and the third direction X and the intersection of the second direction Y and the third direction X may be explained in the same way, and will not be elaborated here.

[0117] As an example, as shown in FIG. 2 to FIG. 8 , the first direction Z is perpendicular to the second direction Y, the first direction Z is perpendicular to the third direction X, and the second direction Y is perpendicular to the third direction X.

[0118] The tray 100 provided in the embodiment of the present application is formed by a limiting structure 20 to define multiple limiting spaces 201 located to the side of the bottom support member 10 along the first direction Z. The projections of the multiple limiting spaces 201 along the first direction Z are different. In this way, each limiting space 201 can be used for a battery whose projection along the first direction Z roughly corresponds to that limiting space 201. For example, the projection of each limiting space 201 along the first direction Z has corresponding dimensions along the second direction Y and dimensions along the third direction X, so that it can be used for batteries with corresponding dimensions along the second direction Y and the third direction X. Therefore, each limiting space 201 can be used to limit a corresponding model of battery. Based on this, the multiple limiting spaces 201 can be used to respectively limit multiple different models of batteries, that is, the tray 100 can be used for multiple different models of batteries. Therefore, compared to a tray 100 that can only be used to limit a single model of battery, the tray 100 provided in the embodiment of the present application has higher compatibility and versatility.

[0119] Moreover, the pallet 100 provided in the embodiment of the present application defines a plurality of limiting spaces 201 through a limiting structure 20, thereby improving the compatibility and versatility of the pallet 100. That is, the compatibility and versatility can be improved through a simple design, thereby reducing the manufacturing cost of the pallet 100 and increasing its scope of application.

[0120] In some embodiments, referring to FIG. 2 and in conjunction with other figures, the tray 100 includes a plurality of limiting structures 20 , each of which can enclose a plurality of limiting spaces 201 .

[0121] The plurality of limiting structures 20 may be disposed on the same side of the bottom supporting member 10 along the first direction Z, or may be disposed on opposite sides of the bottom supporting member 10 along the first direction Z. Furthermore, the plurality of limiting structures 20 located on the same side of the bottom supporting member 10 along the first direction Z may be arranged sequentially along the second direction Y, or along the third direction X, or along directions intersecting the first direction Z, the second direction Y, and the third direction X, or may even be arranged in an array or randomly distributed along multiple different directions.

[0122] As an example, as shown in FIG2 , two limiting structures 20 are provided and are located on the same side of the bottom supporting member 10 along the first direction Z. The two limiting structures 20 are distributed along the second direction Y on the bottom supporting member 10 at intervals.

[0123] This configuration allows the tray 100 to simultaneously position multiple batteries.

[0124] In some embodiments, referring to Figures 4 and 5, 7 and 8, and in conjunction with other figures, at least a portion of the limiting spaces 201 are located on the same side of the bottom support member 10 along the first direction Z, and their projections along the first direction Z are partially overlapped.

[0125] In some possible designs, among the multiple limiting spaces 201 formed by the limiting structure 20, some of the limiting spaces 201 are located on the same side of the bottom supporting member 10 along the first direction Z, and the projections of the multiple limiting spaces 201 located on the same side of the bottom supporting member 10 projected onto the bottom supporting member 10 along the first direction Z are partially overlapped. Alternatively, in other possible designs, as shown in Figures 4 and 5, 7 and 8, among the multiple limiting spaces 201 formed by the limiting structure 20, all of the limiting spaces 201 are located on the same side of the bottom supporting member 10 along the first direction Z, and the projections of all of the limiting spaces 201 formed by the limiting structure 20 along the first direction Z onto the bottom supporting member 10 are partially overlapped.

[0126] By employing the above technical solution, at least a portion of the limiting spaces 201 defined by the limiting structure 20 are located on the same side of the bottom support member 10 along the first direction Z, with their projections along the first direction Z overlapping. In this way, the limiting structure 20 can selectively position corresponding battery models through corresponding limiting spaces 201. Furthermore, the limiting structure 20 has a smaller dimension perpendicular to the first direction Z, thereby reducing the size of the tray 100.

[0127] It can be understood that one limiting structure 20 is used to limit one battery and can be used to limit batteries of various models.

[0128] In some embodiments, referring to Figures 4, 7 and 8, and in combination with other figures, a plurality of limiting spaces 201 are sequentially connected and arranged along the first direction Z.

[0129] As shown in Figures 4, 7 and 8, the plurality of limiting spaces 201 formed by the limiting structure 20 are sequentially arranged along the first direction Z and are sequentially connected along the first direction Z. It can be understood that the plurality of limiting spaces 201 are located on the same side of the bottom supporting member 10 along the first direction Z, and the projections of the plurality of limiting spaces 201 along the first direction Z are arranged to overlap.

[0130] When the limiting structure 20 limits the battery, the battery can be completely accommodated in the corresponding limiting space 201; the battery can also be accommodated in the corresponding limiting space 201 only in a part along the first direction Z, and the other part of the battery along the first direction Z can be accommodated in another one or more adjacent limiting spaces 201 along the first direction Z.

[0131] This arrangement makes the distribution of the plurality of limiting spaces 201 on the limiting structure 20 very clear, making it easier to place batteries in the limiting spaces 201 of corresponding models, thereby improving the efficiency of the tray 100 in limiting batteries. Furthermore, the structure of the limiting structure 20 is very simple.

[0132] In some embodiments, please refer to Figures 9 and 10 together with other figures. Figure 9 is a partial schematic diagram of a tray 100 provided in some embodiments of the present application, and Figure 10 is a cross-sectional view taken along line DD in Figure 9. In a cross section parallel to the first direction Z, at least two limiting spaces 201 are partially overlapped.

[0133] Specifically, among the multiple limiting spaces 201 defined by the limiting structure 20 , at least two limiting spaces 201 are located at the same position of the tray 100 along the first direction Z. Furthermore, when the battery is confined in any one of the two limiting spaces 201 , part of the battery is also accommodated in the other limiting space 201 .

[0134] Such an arrangement can reduce the size of the tray 100 in the first direction Z, thereby facilitating a miniaturized design of the tray 100 .

[0135] In some embodiments, please refer to Figures 2 to 7 together with other figures. The two confined spaces 201 are respectively a first confined space 201a and a second confined space 201b. In the second direction Y, the size of the first confined space 201a is smaller than the size of the second confined space 201b.

[0136] It can be understood that, of the two limiting spaces 201 formed by the limiting structure 20, one limiting space 201 is a first limiting space 201a, and the other limiting space 201 is a second limiting space 201b. In Figures 4, 5, and 7, the first limiting space 201a and the second limiting space 201b are divided by dotted lines.

[0137] Because the size of the first limiting space 201a along the second direction Y is smaller than the size of the second limiting space 201b along the second direction Y, the size of the battery used to be limited by the first limiting space 201a and the size of the battery used to be limited by the second limiting space 201b along the second direction Y are different, that is, the limiting structure 20 can be used to limit batteries with different sizes along the second direction Y.

[0138] In some embodiments, please refer to FIG6 to FIG8 together with other drawings. In the third direction X, the size of the first limiting space 201a is smaller than the size of the second limiting space 201b.

[0139] 7 , the size of the first confined space 201a along the second direction Y is smaller than the size of the second confined space 201b along the second direction Y. As shown in FIG8 , the size of the first confined space 201a along the third direction X is also smaller than the size of the second confined space 201b.

[0140] With such a configuration, the limiting structure 20 can be used to limit batteries having different sizes along the second direction Y and the third direction X.

[0141] It can be understood that the limiting structure 20 can be used to limit at least two batteries of different models, and the two batteries can be set to have different sizes in one direction, or can be set to have different sizes in two non-parallel directions.

[0142] In some embodiments, please refer to Figures 2 to 11 together, and in combination with other drawings. Among them, Figure 11 is a top view of Figure 9. The limiting structure 20 includes at least one set of limiting components 21, and the limiting components 21 include a first limiting member 211, a second limiting member 212, a third limiting member 213 and a fourth limiting member 214. The first limiting member 211 and the second limiting member 212 are distributed on the bottom support member 10 at intervals along the second direction Y. The third limiting member 213 and the fourth limiting member 214 are distributed on the bottom support member 10 at intervals along the third direction X. In addition, the first limiting member 211, the second limiting member 212, the third limiting member 213 and the fourth limiting member 214 surround and form a plurality of limiting spaces 201.

[0143] The first limiting member 211 , the second limiting member 212 , the third limiting member 213 and the fourth limiting member 214 are all components of the limiting structure 20 used to limit the battery.

[0144] It can be understood that the first limiting member 211, the second limiting member 212, the third limiting member 213 and the fourth limiting member 214 constitute multiple limiting spaces 201, and each limiting space 201 can be composed of the first limiting member 211, the second limiting member 212, the third limiting member 213 and the fourth limiting member 214, as shown in Figures 2 to 8. It is also possible that a part of the limiting space 201 is surrounded by the first limiting member 211, the second limiting member 212, the third limiting member 213 and the fourth limiting member 214; another part of the limiting space 201 is surrounded by the first limiting member 211 and the second limiting member 212, or is surrounded by the first limiting member 211, the second limiting member 212 and, for example but not limited to, the fifth limiting member 215 and the sixth limiting member 216 mentioned below; another part of the limiting space 201 is surrounded by the third limiting member 213 and the fourth limiting member 214, or is surrounded by the third limiting member 213, the fourth limiting member 214 and, for example but not limited to, the fifth limiting member 215 and the sixth limiting member 216 mentioned below, as shown in Figures 9 to 11.

[0145] The first limiting member 211 and the second limiting member 212 are spaced apart along the second direction Y, and are used to be disposed on opposite sides of the corresponding limiting space 201 along the second direction Y, thereby limiting the position of the battery in the corresponding limiting space 201 in the second direction Y. The third limiting member 213 and the fourth limiting member 214 are spaced apart along the third direction X, and are used to be disposed on opposite sides of the corresponding limiting space 201 along the third direction X, thereby limiting the position of the battery in the corresponding limiting space 201 in the third direction X.

[0146] The first limiting member 211 , the second limiting member 212 , the third limiting member 213 and the fourth limiting member 214 are used to enclose the same limiting space 201 , and thus can simultaneously limit the battery in the second direction Y and the third direction X.

[0147] By providing the first limiting member 211 , the second limiting member 212 , the third limiting member 213 and the fourth limiting member 214 , the limiting assembly 21 forms a plurality of limiting spaces 201 , so that the tray 100 can be suitable for a variety of different types of batteries, thereby improving the compatibility and versatility of the tray 100 .

[0148] In some embodiments, please refer to Figures 3 to 5 and 12 together, and in combination with other drawings. Among them, Figure 12 is an enlarged view of point E in Figure 3. The first limiting member 211 includes a plurality of first blocks 2111, and the plurality of first blocks 2111 are distributed in sequence along the second direction Y. In the direction in which the first blocks 2111 are away from the second limiting member 212 along the second direction Y, the sizes of the plurality of first blocks 2111 along the first direction Z are gradually increased. Each first block 2111 is used to enclose a limiting space 201 with the second limiting member 212, and the limiting spaces 201 corresponding to the plurality of first blocks 2111 are connected and arranged in sequence along the first direction Z.

[0149] It can be understood that, among any two first blocks 2111 adjacent to each other along the second direction Y, one of the first blocks 2111 is closer to the second stopper 212 along the second direction Y. Furthermore, the size of the first block 2111 closer to the second stopper 212 along the second direction Y in the first direction Z is smaller than the size of the other second block 2121 in the first direction Z.

[0150] For ease of description, of any two first sub-blocks 2111 adjacent to each other along the second direction Y, the first sub-block 2111 closer to the second stopper 212 along the second direction Y is defined as the first first sub-block 2111a, and the other first sub-block 2111 is defined as the second first sub-block 2111b. The second first sub-block 2111b extends beyond the first first sub-block 2111a along the first direction Z.

[0151] It should be noted that the first first sub-block 2111a can define a confined space 201 with the second confining member 212, and the portion of the second first sub-block 2111b that extends beyond the first first sub-block 2111a along the first direction Z can also define another first confined space 201a with the second confining member 212. The confined space 201 corresponding to the first first sub-block 2111a can be the first confined space 201a, and the confined space 201 corresponding to the second first sub-block 2111b can be the second confined space 201b. The first confined space 201a and the second confined space 201b are sequentially distributed along the first direction Z and are sequentially connected along the first direction Z. Based on the sequential distribution of the first first sub-block 2111a and the second first sub-block 2111b along the second direction Y, the size of the second confined space 201b along the second direction Y is larger than the size of the first confined space 201a along the second direction Y.

[0152] When the battery is confined in the first confining space 201a, at least a portion of the battery is located between the second confining member 212 and the first first sub-block 2111a, so that the second confining member 212 and the first first sub-block 2111a respectively confine the battery on opposite sides along the second direction Y. In other words, the second confining member 212 and the first first sub-block 2111a jointly confine the battery in the second direction Y.

[0153] When the battery is confined in the second confining space 201b, at least a portion of the battery is located between the portion of the second first sub-block 2111b that extends beyond the first first sub-block 2111a along the first direction Z and the second confining member 212. This allows the portion of the second first sub-block 2111b that extends beyond the first first sub-block 2111a along the first direction Z and the second confining member 212 to confine the battery on opposite sides along the second direction Y. In other words, the second confining member 212 and the second first sub-block 2111b together confine the battery in the second direction Y. Furthermore, the battery can be supported along the first direction Z by the end of the first first sub-block 2111a that is away from the bottom support member 10 along the first direction Z, thereby achieving a supporting and confining effect on the battery on the tray 100.

[0154] The battery confined in the first confined space 201a may be completely accommodated in the first confined space 201a, or a portion of the battery may be accommodated in the first confined space 201a and the other portion of the battery may be accommodated in the second confined space 201b.

[0155] It can be understood that each of the multiple first sub-blocks 2111 of the first limiting member 211 can define a limiting space 201 with the second limiting member 212, such that one first sub-block 2111 corresponds to one limiting space 201. The multiple limiting spaces 201 corresponding one-to-one with the multiple first sub-blocks 2111 are sequentially distributed and connected along the first direction Z. Furthermore, as the first limiting member 211 moves away from the base member 10 along the first direction Z, the multiple limiting spaces 201 corresponding one-to-one with the multiple first sub-blocks 2111 gradually increase in size in the second direction Y.

[0156] This arrangement allows each first block 2111 to define a confined space 201 with the second limiting member 212. Consequently, the multiple confined spaces 201 defined by the first limiting member 211 and the second limiting member 212 are arranged to be sequentially connected along the first direction Z, and to have gradually increasing sizes in the second direction Y. This allows the multiple confined spaces 201 defined by the first limiting member 211 and the second limiting member 212 to be used to separately confine batteries of different sizes along the second direction Y. Furthermore, this facilitates the placement of batteries into the confined spaces 201.

[0157] In some embodiments, referring to FIG12 and in combination with other drawings, the plurality of first blocks 2111 of the first position-limiting member 211 are sequentially connected along the second direction Y to form a step structure.

[0158] With such configuration, the size of the first limiting member 211 in the second direction Y can be reduced.

[0159] In some embodiments, the plurality of first blocks 2111 are distributed along the second direction Y at intervals.

[0160] Such an arrangement enables the multiple first blocks 2111 of the first position-limiting member 211 to be arranged separately, thereby making the arrangement flexibility of the first position-limiting member 211 higher.

[0161] In some embodiments, please refer to Figures 3 to 5 and Figure 13 in conjunction with other accompanying drawings. Figure 13 is an enlarged view of point F in Figure 3. The second limiting member 212 includes a plurality of second blocks 2121, which are sequentially distributed along the second direction Y. As the second blocks 2121 move away from the first blocks 2111 along the second direction Y, the plurality of second blocks 2121 are arranged with increasing dimensions along the first direction Z. Each second block 2121 is used to enclose a limiting space 201 with the corresponding first block 2111.

[0162] As shown in Figures 3 to 5, 12, and 13, the number of first blocks 2111 and second blocks 2121 is the same, and the multiple first blocks 2111 are arranged in a one-to-one correspondence with the multiple second blocks 2121. The size of each first block 2111 in the first direction Z is the same as the size of the corresponding second block 2121 in the first direction Z. Each first block 2111 and the corresponding second block 2121 define the same confined space 201.

[0163] When at least part of the battery is limited in the limiting space 201 defined by the first block 2111 and the corresponding second block 2121, at least part of the battery is located between the first block 2111 and the corresponding second block 2121, and the first block 2111 and the corresponding second block 2121 jointly realize the limitation of the battery in the second direction Y.

[0164] This arrangement allows the plurality of first sub-blocks 2111 to correspond to the plurality of second sub-blocks 2121, thereby forming a plurality of confined spaces 201 that are sequentially connected along the first direction Z. Furthermore, the plurality of confined spaces 201 have different sizes along the second direction Y to accommodate batteries of different sizes along the second direction Y. Furthermore, this facilitates the placement of batteries into the confined spaces 201.

[0165] Moreover, when the battery is limited in the second limiting space 201b, the battery can be connected to the first first block 2111a along the first direction Z, and connected to the second block 2121 corresponding to the first first block 2111a along the first direction Z, thereby achieving a stable placement of the battery on the tray 100.

[0166] In some embodiments, the second limiting member 212 may not include multiple second sub-blocks 2121. Based on this, the bottom support member 10 may be provided with a movable member capable of receiving the battery along the first direction Z. When a battery needs to be confined to a corresponding limiting space 201, for example, a battery needs to be confined to the second limiting space 201b, the battery can be received by the first first sub-block 2111a along the first direction Z. Furthermore, the movable member can be moved along the first direction Z to a predetermined position to receive the battery along the first direction Z. In this manner, the battery can be stably placed on the tray 100.

[0167] In some embodiments, referring to FIG13 and in combination with other drawings, the plurality of second segments 2121 of the second position-limiting member 212 are sequentially connected along the second direction Y to form a step structure.

[0168] With such configuration, the size of the second limiting member 212 along the second direction Y can be reduced.

[0169] In some embodiments, the plurality of second blocks 2121 are distributed along the second direction Y at intervals.

[0170] Such an arrangement enables the plurality of second segments 2121 of the second position-limiting member 212 to be arranged separately, thereby making the arrangement of the second position-limiting member 212 more flexible.

[0171] In some embodiments, please refer to Figures 6 to 8, Figure 14, and other accompanying drawings. Figure 14 is an enlarged view of point G in Figure 6. The third limiting member 213 includes a plurality of third blocks 2131. The plurality of third blocks 2131 are distributed in sequence along the third direction X. In the direction in which the third blocks 2131 are away from the fourth limiting member 214 along the third direction X, the sizes of the plurality of third blocks 2131 along the first direction Z are gradually increased. Each third block 2131 is used to enclose a limiting space 201 with the fourth limiting member 214, and the limiting spaces 201 corresponding to the plurality of third blocks 2131 are respectively connected and arranged in sequence along the first direction Z.

[0172] It can be understood that, among any two third blocks 2131 adjacent to each other along the third direction X, one of the third blocks 2131 is closer to the fourth limiting member 214 along the third direction X. Furthermore, the dimension of the third block 2131 closer to the fourth limiting member 214 along the third direction X in the first direction Z is smaller than the dimension of the other third block 2131 in the first direction Z.

[0173] For ease of description, of any two third sub-blocks 2131 adjacent along the third direction X, the third sub-block 2131 closer to the fourth limiting member 214 along the third direction X is defined as the first third sub-block 2131a, and the other third sub-block 2131 is defined as the second third sub-block 2131b. The second third sub-block 2131b extends beyond the first third sub-block 2131a along the first direction Z.

[0174] It should be noted that the first third block 2131a can define a confined space 201 with the fourth limiting member 214, and the portion of the second third block 2131b that extends beyond the first third block 2131a along the first direction Z can define another first confined space 201a with the fourth limiting member 214. The confined space 201 corresponding to the first third block 2131a can be the first confined space 201a, and the confined space 201 corresponding to the second third block 2131b can be the second confined space 201b. The first confined space 201a and the second confined space 201b are sequentially distributed along the first direction Z and are sequentially connected along the first direction Z. Based on the sequential distribution of the first third block 2131a and the second third block 2131b along the third direction X, the size of the second confined space 201b along the third direction X is larger than the size of the first confined space 201a along the third direction X.

[0175] When the battery is confined in the first confining space 201a, at least a portion of the battery is located between the fourth confining member 214 and the first third sub-block 2131a, so that the fourth confining member 214 and the first third sub-block 2131a respectively confine the battery on opposite sides along the third direction X. In other words, the fourth confining member 214 and the first third sub-block 2131a jointly confine the battery in the third direction X.

[0176] When the battery is confined in the second limiting space 201b, at least a portion of the battery is located between the portion of the second third block 2131b that extends beyond the first third block 2131a along the first direction Z and the fourth limiting member 214. This allows the portion of the second third block 2131b that extends beyond the first third block 2131a along the first direction Z and the fourth limiting member 214 to limit the battery on opposite sides along the third direction X. In other words, the fourth limiting member 214 and the second third block 2131b jointly limit the battery in the third direction X. Furthermore, the battery can be supported along the first direction Z at the end of the first third block 2131a that is away from the bottom support member 10 along the first direction Z, thereby achieving a supporting and limiting effect on the battery on the tray 100.

[0177] The battery confined in the first confined space 201a may be completely accommodated in the first confined space 201a, or a portion of the battery may be accommodated in the first confined space 201a and the other portion of the battery may be accommodated in the second confined space 201b.

[0178] It can be understood that each of the multiple third blocks 2131 of the third limiting member 213 can define a limiting space 201 with the fourth limiting member 214, such that one third block 2131 corresponds to one limiting space 201. The multiple limiting spaces 201 corresponding one-to-one with the multiple third blocks 2131 are sequentially distributed along the first direction Z and are sequentially connected. Furthermore, as the third limiting member 213 moves away from the base member 10 along the first direction Z, the multiple limiting spaces 201 corresponding one-to-one with the multiple third blocks 2131 gradually increase in size in the third direction X.

[0179] This arrangement allows each third block 2131 to define a limiting space 201 with the fourth limiting member 214. Consequently, the multiple limiting spaces 201 defined by the third limiting member 213 and the fourth limiting member 214 are arranged to be sequentially connected along the first direction Z, and to have increasing sizes along the third direction X. This allows the multiple limiting spaces 201 defined by the third limiting member 213 and the fourth limiting member 214 to be used to separately limit batteries of different sizes along the third direction X. This also facilitates the placement of batteries into the limiting spaces 201.

[0180] In some embodiments, referring to FIG14 and in combination with other drawings, the plurality of third blocks 2131 of the third position-limiting member 213 are sequentially connected along the third direction X to form a step structure.

[0181] With such configuration, the size of the third limiting member 213 in the third direction X can be reduced.

[0182] In some embodiments, among the plurality of third blocks 2131 of the third limiting member 213 , the plurality of third blocks 2131 are distributed at intervals along the third direction X.

[0183] Such an arrangement enables the multiple third blocks 2131 of the third position-limiting member 213 to be arranged separately, thereby making the arrangement flexibility of the third position-limiting member 213 higher.

[0184] In some embodiments, please refer to Figures 6 to 8, Figure 14, and Figure 15 together, and in conjunction with other figures. Figure 15 is an enlarged view of point H in Figure 6. The fourth limiting member 214 includes a plurality of fourth blocks 2141, and the plurality of fourth blocks 2141 are sequentially distributed along the third direction X. In the direction in which the fourth blocks 2141 are away from the third block 2131 along the third direction X, the plurality of fourth blocks 2141 are arranged with increasing sizes along the first direction Z. Each fourth block 2141 is used to enclose a limiting space 201 with the corresponding third block 2131.

[0185] As shown in Figures 6 to 8, 14, and 15, the number of third blocks 2131 and fourth blocks 2141 is the same, and the plurality of third blocks 2131 and the plurality of fourth blocks 2141 are arranged in a one-to-one correspondence. The size of each third block 2131 in the first direction Z is the same as the size of the corresponding fourth block 2141 in the first direction Z. Each third block 2131 and the corresponding fourth block 2141 define the same confined space 201.

[0186] When at least part of the battery is limited in the limiting space 201 defined by the third block 2131 and the corresponding fourth block 2141, at least part of the battery is located between the third block 2131 and the corresponding fourth block 2141, and the third block 2131 and the corresponding fourth block 2141 jointly realize the limitation of the battery in the third direction X.

[0187] This arrangement enables the corresponding arrangement of the plurality of third sub-blocks 2131 and the plurality of fourth sub-blocks 2141, thereby facilitating the formation of a plurality of confined spaces 201 that are sequentially connected along the first direction Z. Furthermore, the plurality of confined spaces 201 have different sizes along the third direction X to accommodate batteries having different sizes along the third direction X. Furthermore, this facilitates the placement of batteries into the confined spaces 201.

[0188] Moreover, when the battery is limited in the second limiting space 201b, the battery can be connected to the first third block 2131a along the first direction Z, and connected to the fourth block 2141 corresponding to the first third block 2131a along the first direction Z, thereby achieving a stable placement of the battery on the tray 100.

[0189] In some embodiments, the fourth limiting member 214 may not include multiple fourth sub-blocks 2141. Based on this, the bottom support member 10 may be provided with a movable member capable of receiving the battery along the first direction Z. When a battery needs to be confined to a corresponding limiting space 201, for example, a battery needs to be confined to the second limiting space 201b, the battery can be received by the first third sub-block 2131a along the first direction Z. Furthermore, the movable member can be moved along the first direction Z to a predetermined position to receive the battery along the first direction Z. In this manner, the battery can be stably placed on the tray 100.

[0190] In some embodiments, referring to FIG15 and in combination with other drawings, the plurality of fourth segments 2141 of the fourth position-limiting member 214 are sequentially connected along the third direction X to form a step structure.

[0191] With such configuration, the size of the fourth limiting member 214 in the third direction X can be reduced.

[0192] In some embodiments, among the plurality of fourth blocks 2141 of the fourth limiting member 214 , the plurality of fourth blocks 2141 are distributed along the third direction X at intervals.

[0193] Such an arrangement enables the plurality of fourth segments 2141 of the fourth position-limiting member 214 to be arranged separately, thereby making the arrangement of the fourth position-limiting member 214 more flexible.

[0194] Based on the above structure, the limiting structure 20 can be provided with multiple limiting members to enclose multiple limiting spaces 201 with different projections along the first direction Z, so that the structure of the tray 100 is very simple and the manufacturing cost is very low.

[0195] Based on the above structure, each first block 2111 may correspond to a confined space 201, and each third block 2131 may also correspond to a confined space 201. There may be a certain connection between the confined space 201 corresponding to the first block 2111 and the confined space 201 corresponding to the third block 2131, and the details will be described in the embodiments below.

[0196] In some embodiments, referring to FIG. 6 to FIG. 8 and other figures, at least one limiting space 201 is formed by the first block 2111 , the second limiting member 212 , the third block 2131 and the fourth limiting member 214 .

[0197] It is understood that at least one of the plurality of confined spaces 201 corresponding one-to-one with the plurality of first blocks 2111 is the same confined space 201 as at least one of the plurality of confined spaces 201 corresponding one-to-one with the plurality of third blocks 2131. That is, at least one confined space 201 is encompassed by both the first block 2111 and the second confining member 212, and the corresponding third block 2131 and the fourth confining member 214. Based on this, when the battery is confined within the confined space 201 encompassed by the first block 2111, the second confining member 212, the third block 2131, and the fourth confining member 214, at least a portion of the battery is located between the first block 2111 and the second confining member 212, and between the corresponding third block 2131 and the fourth confining member 214. The first block 2111 and the second limiting member 212 jointly limit the battery in the second direction Y, and the third block 2131 and the fourth limiting member 214 jointly limit the battery in the third direction X.

[0198] When the second position-limiting member 212 includes a plurality of second sub-blocks 2121, the first sub-block 2111 and the corresponding second sub-block 2121 jointly limit the battery in the second direction Y. When the fourth position-limiting member 214 includes a plurality of fourth sub-blocks 2141, the third sub-block 2131 and the corresponding fourth sub-block 2141 jointly limit the battery in the third direction X.

[0199] By adopting the above technical solution, at least one limiting space 201 can limit the battery along the second direction Y and the third direction X respectively.

[0200] 6 to 8 , each limiting space 201 is collectively formed by each first segment 2111, each third segment 2131, the second limiting member 212, and the fourth limiting member 214. In FIG2 to 5 , the first limiting member 211 is divided into a plurality of first segments 2111, and the third limiting member 213 is not divided into a plurality of third segments 2131. Instead, each limiting space 201 is collectively formed by the first segment 2111, the second limiting member 212, the third limiting member 213, and the fourth limiting member 214.

[0201] In some embodiments, please refer to FIG. 6 to FIG. 8 in conjunction with other drawings. Each first block 2111 and each third block 2131 , the second limiting member 212 , and the fourth limiting member 214 define each limiting space 201 .

[0202] It can be understood that all first blocks 2111 of the first limiting member 211 correspond one-to-one to all third blocks 2131 of the third limiting member 213, and each first block 2111, together with the corresponding third block 2131, the second limiting member 212, and the fourth limiting member 214, form a limiting space 201. That is, among the multiple limiting spaces 201 formed by the limiting structure 20, each limiting space 201 is formed by the corresponding first block 2111, the third block 2131, the second limiting member 212, and the fourth limiting member 214.

[0203] Based on this, the plurality of confined spaces 201 formed by the confining structure 20 are sequentially connected and arranged along the first direction Z. Any two confined spaces 201 sequentially distributed along the first direction Z can be the first confined space 201a and the second confined space 201b, respectively. The size of the first confined space 201a along the second direction Y is smaller than the size of the second confined space 201b along the second direction Y, and the size of the first confined space 201a along the third direction X is smaller than the size of the second confined space 201b along the third direction X.

[0204] The first block 2111 corresponding to the first confined space 201a is the first first block 2111a, the first block 2111 corresponding to the second confined space 201b is the second first block 2111b, the third block 2131 corresponding to the first confined space 201a is the first third block 2131a, and the third block 2131 corresponding to the second confined space 201b is the second third block 2131b. When the battery is confined in the second confined space 201b, the second first block 2111b and the second limiting member 212 jointly limit the battery in the second direction Y, and the second third block 2131b and the fourth limiting member 214 jointly limit the battery in the third direction X. Furthermore, the battery can be connected to the first first block 2111a along the first direction Z, or it can be connected to the first third block 2131a along the first direction Z at the same time.

[0205] By employing the above-described technical solution, the plurality of limiting spaces 201 defined by the limiting structure 20 can accommodate batteries of different models, and the dimensions of two battery models can differ in both the second direction Y and the third direction X. In other words, the limiting structure 20 can accommodate batteries of different models having different dimensions in both the second direction Y and the third direction X, thereby making the tray 100 highly compatible and versatile.

[0206] In some embodiments, please refer to Figures 16 to 18 in conjunction with other figures. Figure 16 is a partial top view of a tray 100 provided in some embodiments of the present application, Figure 17 is a cross-sectional view taken along line II in Figure 16 , and Figure 18 is a cross-sectional view taken along line JJ in Figure 16 . Multiple first sub-blocks 2111, each together with the same third sub-block 2131, form a confined space 201.

[0207] It can be understood that each first block 2111 corresponds to a respective confined space 201, and each third block 2131 also corresponds to a respective confined space 201. The multiple confined spaces 201 corresponding to the multiple first blocks 2111 are arranged in sequence along the first direction Z. Furthermore, among the multiple confined spaces 201 sequentially connected along the first direction Z, any first confined space 201a is the same confined space 201 as the confined space 201 corresponding to one of the third blocks 2131, so that the multiple confined spaces 201 have different sizes along the second direction Y and the same size along the third direction X.

[0208] As an example, as shown in Figures 16 to 18, two adjacent first blocks 2111 are respectively set as a first first block 2111a and a second first block 2111b. The first first block 2111a corresponds to the first confined space 201a, and the second first block 2111b corresponds to the second confined space 201b. The first confined space 201a and the confined space 201 corresponding to one of the third blocks 2131 are the same confined space 201, and the second confined space 201b and the confined space 201 corresponding to the third block 2131 are also the same confined space 201. Based on this, the size of the first confined space 201a along the second direction Y is smaller than the size of the second confined space 201b along the second direction Y, and the size of the first confined space 201a along the third direction X is the same as the size of the second confined space 201b along the third direction X. Furthermore, when the battery is confined in the first confining space 201a, the first first sub-block 2111a and the third sub-block 2131 respectively confine the battery in the second direction Y and the third direction X. When the battery is confined in the second confining space 201b, the second first sub-block 2111b and the third sub-block 2131 respectively confine the battery in the second direction Y and the third direction X.

[0209] It should be supplemented here that, based on the third limiting member 213 being divided into a plurality of third blocks 2131 , the plurality of limiting spaces 201 corresponding one-to-one to the plurality of third blocks 2131 have different sizes in the third direction X.

[0210] In this way, the multiple limiting spaces 201 formed by the limiting structure 20 can be used to adapt to different types of batteries with different sizes along the second direction Y, and can also be used to adapt to different types of batteries with different sizes along the third direction X, so that the compatibility and versatility of the tray 100 are very high.

[0211] It should be additionally explained that, when the third limiting member 213 is not divided into a plurality of third blocks 2131 , the third limiting member 213 may also jointly enclose the limiting space 201 with the first block 2111 , the second limiting member 212 , and the fourth limiting member 214 .

[0212] Based on this, the plurality of confining spaces 201 corresponding one-to-one to the plurality of first sub-blocks 2111 are all the confining spaces 201 formed by the confining structure 20, and all the confining spaces 201 are sequentially connected and arranged along the first direction Z. Furthermore, the dimensions of the plurality of confining spaces 201 along the second direction Y are different, and the dimensions of the plurality of confining spaces 201 along the third direction X are the same, so that the confining structure 20 can be used to confine batteries of different models having different dimensions along the second direction Y.

[0213] In some embodiments, referring to FIG9 to FIG11 together with other drawings, at least one confined space 201 corresponding to the first block 2111 and any confined space 201 corresponding to the third block 2131 are different confined spaces 201 .

[0214] It can be understood that at least one limit space 201 corresponding to the first block 2111 and any limit space 201 corresponding to the third block 2131 are different limit spaces 201, and the limit space 201 corresponding to the first block 2111 and the limit space 201 corresponding to the third block 2131 can be arranged in sequence along the first direction Z, or they can be located at the same position of the pallet 100 along the first direction Z.

[0215] The sizes of the plurality of limiting spaces 201 corresponding to the plurality of first blocks 2111 along the second direction Y are different; the sizes of the plurality of limiting spaces 201 corresponding to the plurality of third blocks 2131 along the third direction X are different.

[0216] As an example, as shown in Figures 9 to 11, the limit space 201 corresponding to one of the first blocks 2111 is set as the third limit space 201c, and the limit space 201 corresponding to one of the second blocks 2121 is set as the fourth limit space 201d. The third limit space 201c and the fourth limit space 201d are different limit spaces 201.

[0217] Among them, when the battery is limited to the third limiting space 201c, the first block 2111 and the second limiting member 212 jointly realize the limitation of the battery along the second direction Y. When it is necessary to limit the battery in the third direction X, the fifth limiting member 215 and the sixth limiting member 216 mentioned below can be set, and the battery in the third direction X can be limited by the fifth limiting member 215 and the sixth limiting member 216. When the battery is limited to the fourth limiting space 201d, the third block 2131 and the fourth limiting member 214 jointly realize the limitation of the battery along the third direction X. When it is necessary to limit the battery in the second direction Y, the fifth limiting member 215 and the sixth limiting member 216 mentioned below can be set, and the battery in the second direction Y can be limited by the fifth limiting member 215 and the sixth limiting member 216.

[0218] In some possible designs, the confined space 201 corresponding to any first sub-block 2111 and the confined space 201 corresponding to any third sub-block 2131 are different confined spaces 201. That is, the first sub-block 2111 and the third sub-block 2131 do not enclose a confined space 201. Based on this, the battery can be selectively confined in the confined space 201 corresponding to the first sub-block 2111 or the confined space 201 corresponding to the third sub-block 2131.

[0219] The first block 2111 can only form the limiting space 201 with the second limiting member 212, and the first block 2111 and the second limiting member 212 can jointly limit the battery in the second direction Y. The first block 2111 can also simultaneously form the limiting space 201 with the second limiting member 212, and can be, but not limited to, the fifth limiting member 215 and the sixth limiting member 216 described below, and the first block 2111, the second limiting member 212, the fifth limiting member 215, and the sixth limiting member 216 can jointly limit the battery in the second direction Y and the third direction X. Correspondingly, the third block 2131 can only form the limiting space 201 with the fourth limiting member 214, and the third block 2131 and the fourth limiting member 214 can jointly limit the battery in the third direction X. The third block 2131 can also simultaneously form a limiting space 201 together with the fourth limiting member 214, which may be but is not limited to the fifth limiting member 215 and the sixth limiting member 216 mentioned below, and the battery is limited in the second direction Y and the third direction X through the third block 2131, the fourth limiting member 214, the fifth limiting member 215 and the sixth limiting member 216.

[0220] In some other possible designs, the limiting space 201 corresponding to a part of the first block 2111 and the limiting space 201 corresponding to the third block 2131 are different limiting spaces 201; and another part of the first block 2111 can be together with the corresponding third block 2131 to form the limiting space 201, that is, the first block 2111 can be together with the corresponding third block 2131, the second limiting member 212, and the fourth limiting member 214 to form the limiting space 201.

[0221] Such arrangement enables at least one first block 2111 and the third block 2131 to respectively define different limiting spaces 201, that is, the limiting space 201 corresponding to at least one first block 2111 and the limiting space 201 defined by the third block 2131 are different limiting spaces 201, so that the limiting structure 20 can define a variety of different limiting spaces 201 and can be compatible with more models of batteries.

[0222] In some embodiments, please refer to Figures 9 to 11 in conjunction with other figures. The limiting assembly 21 further includes a fifth limiting member 215 and a sixth limiting member 216. The fifth limiting member 215 is disposed between the first block 2111 and the third block 2131, and the sixth limiting member 216 is disposed between the second limiting member 212 and the fourth limiting member 214. The fifth limiting member 215 and the sixth limiting member 216 are used to form the limiting space 201 together with the first block 2111 and the second limiting member 212, and are also used to form the limiting space 201 together with the third block 2131 and the fourth limiting member 214.

[0223] It can be understood that the limit space 201 corresponding to one of the first blocks 2111 is set as the third limit space 201c, and the limit space 201 corresponding to one of the third blocks 2131 is set as the fourth limit space 201d. The third limit space 201c and the fourth limit space 201d are different limit spaces 201.

[0224] The third limiting space 201c is enclosed by the first block 2111, the second limiting member 212, the fifth limiting member 215, and the sixth limiting member 216, forming the limiting space 201. When the battery is confined in the third limiting space 201c, the first block 2111 and the second limiting member 212 jointly limit the battery in the second direction Y, and the fifth limiting member 215 and the sixth limiting member 216 jointly limit the battery in the third direction X.

[0225] The fourth limiting space 201d is enclosed by the third block 2131, the fourth limiting member 214, the fifth limiting member 215, and the sixth limiting member 216. When the battery is confined in the fourth limiting space 201d, the third block 2131 and the fourth limiting member 214 jointly limit the battery in the third direction X, and the fifth limiting member 215 and the sixth limiting member 216 jointly limit the battery in the second direction Y.

[0226] Among them, the fifth limiting member 215 is arranged between the first block 2111 and the third block 2131, and the sixth limiting member 216 is arranged between the second limiting member 212 and the fourth limiting member 214, so that the setting of the fifth limiting member 215 and the sixth limiting member 216 will not make the size of the limiting space 201 too small, which is conducive to limiting the battery within the limiting space 201.

[0227] By adopting the above technical solution, the limiting space 201 corresponding to one of the first blocks 2111 and the limiting space 201 corresponding to any third block 2131 can limit the battery in the second direction Y and the third direction X to maintain the limiting stability of the battery.

[0228] In some embodiments, please refer to FIG2 and FIG3 together with other drawings. The limiting structure 20 further includes a support member 22 disposed on the bottom bracket 10, and the support member 22 is used to support the battery along the first direction Z.

[0229] As shown in Figure 3, the support member 22 is also used to assist in forming a limited space 201 closest to the bottom support member 10 along the first direction Z. In this way, when the battery is limited in the limited space 201 closest to the bottom support member 10 along the first direction Z, the support member 22 is supported by the battery along the first direction Z.

[0230] Such a configuration enables the support member 22 to support the battery along the first direction Z, so as to maintain the position stability of the battery on the tray 100 .

[0231] In some embodiments, the first limiting member 211 , the second limiting member 212 , the third limiting member 213 and the fourth limiting member 214 are connected in sequence around the first direction Z.

[0232] With such configuration, the limiting structure 20 is substantially annular in shape.

[0233] In some embodiments, please refer to FIG. 3 to FIG. 18 in conjunction with other drawings. The first limiting member 211 is connected to the third limiting member 213 .

[0234] Because the first limiting member 211 and the second limiting member 212 are spaced apart along the second direction Y, the third limiting member 213 and the first limiting member 211 can both be spaced apart from the second limiting member 212 along the second direction Y. Because the third limiting member 213 and the fourth limiting member 214 are spaced apart along the third direction X, the first limiting member 211 and the third limiting member 213 can both be spaced apart from the fourth limiting member 214 along the third direction X. This arrangement allows the limiting structure 20 to effectively avoid the handling device used to carry the batteries, facilitating the positioning of the batteries on the tray 100.

[0235] In some embodiments, please refer to FIG. 3 to FIG. 18 in conjunction with other drawings. The second limiting member 212 is connected to the fourth limiting member 214 .

[0236] Because the first limiting member 211 and the second limiting member 212 are spaced apart along the second direction Y, the fourth limiting member 214 and the second limiting member 212 can both be spaced apart from the first limiting member 211 along the second direction Y. Because the third limiting member 213 and the fourth limiting member 214 are spaced apart along the third direction X, the second limiting member 212 and the fourth limiting member 214 can both be spaced apart from the third limiting member 213 along the third direction X. This arrangement allows the limiting structure 20 to effectively avoid the handling device used to carry the batteries, facilitating the positioning of the batteries on the tray 100.

[0237] The first limiting member 211 and the third limiting member 213 may be connected to form an L-shaped structure. The second limiting member 212 and the fourth limiting member 214 may also be connected to form an L-shaped structure.

[0238] In addition, in other embodiments, the first limiting member 211 and the third limiting member 213 , and the second limiting member 212 and the fourth limiting member 214 are spaced apart.

[0239] In some embodiments, a side of the first limiting member 211 along the second direction Y facing the second limiting member 212 is provided with an avoiding groove 202 , and a side of the second limiting member 212 along the second direction Y facing the first limiting member 211 is also provided with an avoiding groove 202 .

[0240] Alternatively, as shown in Figures 3, 12 and 13, the third limiting member 213 is provided with an avoidance groove 202 on one side facing the fourth limiting member 214 along the third direction X, and the fourth limiting member 214 is also provided with an avoidance groove 202 on one side facing the third limiting member 213 along the third direction X.

[0241] The avoidance groove 202 is communicated with the limiting space 201 .

[0242] With such arrangement, when at least a portion of the battery is confined in the avoidance groove 202 , the battery pole or other components can be avoided in the avoidance groove 202 .

[0243] In some embodiments, the limiting structure 20 includes multiple groups of limiting components 21. The provision of multiple groups of limiting components 21 can improve the stability of the limiting effect of the limiting structure 20 on the battery.

[0244] As an example, as shown in Figures 2 and 3, the limiting assemblies 21 are provided in two groups, and the first limiting members 211 of the two groups of limiting assemblies 21 are spaced apart along the third direction X, and the second limiting members 212 of the two groups of limiting assemblies 21 are spaced apart along the third direction X. The third limiting assemblies 21 of the two groups of limiting assemblies 21 are spaced apart along the third direction X, and the fourth limiting members 214 of the two groups of limiting assemblies 21 are spaced apart along the third direction X.

[0245] In some embodiments, the limiting structure 20 is made of a soft material.

[0246] Specifically, the first limiting member 211 , the second limiting member 212 , the third limiting member 213 , the fourth limiting member 214 , the fifth limiting member 215 , the sixth limiting member 216 , the supporting member 22 , etc. are all made of soft materials.

[0247] With such an arrangement, when the limiting structure 20 limits the battery, the limiting structure 20 is in soft contact with the surface of the battery, thereby alleviating the problem of battery damage.

[0248] In some embodiments, the piece of elastic material.

[0249] Specifically, the first limiting member 211 , the second limiting member 212 , the third limiting member 213 , the fourth limiting member 214 , the fifth limiting member 215 , the sixth limiting member 216 , the supporting member 22 , etc. are all made of elastic materials.

[0250] With such a configuration, when the limiting structure 20 limits the battery, the limiting structure 20 elastically contacts the surface of the battery, thereby providing buffer protection for the battery and improving the problem of battery damage.

[0251] As an example, the limiting structure 20 can be made of materials such as nylon, polyoxymethylene, polyurethane, rubber, and silicone.

[0252] Based on the above concept, referring to FIG. 1 and in conjunction with the other accompanying drawings, this embodiment of the present application further provides a battery processing device 1000, which includes a tray 100. The tray 100 in this embodiment is identical to the tray 100 in the previous embodiment. For details, please refer to the description of the tray 100 in the previous embodiment, which will not be repeated here.

[0253] The battery processing equipment 1000 provided in the embodiment of the present application also has the advantage of being compatible with a variety of different types of batteries by adopting the tray 100 involved in the above embodiments.

[0254] Based on the above concept, an embodiment of the present application also provides a battery production line, including battery processing equipment 1000.

[0255] The battery production line provided in the embodiment of the present application also has the advantage of being compatible with a variety of different models of batteries by adopting the battery processing equipment 1000 involved in the above embodiments.

[0256] As one embodiment of the present application, as shown in Figures 2 to 5, a tray 100 includes a bottom support member 10 and a limiting structure 20. The limiting structure 20 is disposed on one side of the bottom support member 10 along a first direction Z to enclose a plurality of limiting spaces 201 located on the same side of the bottom support member 10 along the first direction Z. The projections of the plurality of limiting spaces 201 along the first direction Z are different and partially overlap.

[0257] The limiting structure 20 includes two groups of limiting assemblies 21, each group of limiting assemblies 21 includes a first limiting member 211, a second limiting member 212, a third limiting member 213, and a fourth limiting member 214. The first limiting members 211 and the second limiting members 212 are spaced apart along the second direction Y, and the third limiting members 213 and the fourth limiting members 214 are spaced apart along the third direction X. The first limiting member 211 includes a plurality of first blocks 2111 sequentially distributed along the second direction Y, and the second limiting member 212 includes a plurality of second blocks 2121 sequentially distributed along the second direction Y. As the first blocks 2111 move away from the second blocks 2121 along the second direction Y, the plurality of first blocks 2111 are arranged with increasing sizes along the first direction Z. As the second blocks 2121 move away from the first blocks 2111 along the second direction Y, the plurality of second blocks 2121 are arranged with increasing sizes along the first direction Z. The plurality of first sub-blocks 2111 correspond one-to-one with the plurality of second sub-blocks 2121, and each first sub-block 2111 and the corresponding second sub-block 2121 have the same size along the first direction Z. The first sub-blocks 2111 and the corresponding second sub-blocks 2121, the third limiting members 213, and the fourth limiting members 214 of the two sets of limiting assemblies 21 collectively enclose the limiting spaces 201. The plurality of limiting spaces 201 are arranged in sequence along the first direction Z, and the sizes of the plurality of limiting spaces 201 along the second direction Y gradually increase as the limiting structure 20 moves away from the base member 10 along the first direction Z.

[0258] Based on this, the limiting structure 20 can be used to limit batteries of various sizes and sizes along the second direction Y. When the battery is limited in the limiting space 201, the first limiting members 211 and the second limiting members 212 of the two limiting assemblies 21 both limit the battery along the second direction Y, and the third limiting members 213 and the fourth limiting members 214 of the two limiting assemblies 21 both limit the battery along the third direction X.

[0259] Furthermore, the first limiting member 211 and the third limiting member 213 of each limiting assembly 21 are connected to form an "L"-shaped structure, and the second limiting member 212 and the fourth limiting member 214 are also connected to form an "L"-shaped structure. Thus, the two limiting assemblies 21 together form four "L"-shaped structures, and the four "L"-shaped structures are located at the four vertices of the square space. The length and width of the square space are respectively the second direction Y and the third direction X.
