[0034] In order to make the objectives, technical solutions and advantages of the present application more clearly understood, the present application is further described in detail below in combination with specific embodiments and with reference to the accompanying drawings.

[0035] It should be noted that, unless otherwise defined, the technical terms or scientific terms used in the embodiments of the present application should be the usual meanings understood by people with ordinary skills in the field to which the present application belongs. The "first", "second" and similar words used in the present application do not represent any order, quantity or importance, but are only used to distinguish different components. "Including" or "comprising" and similar words mean that the elements or objects appearing in front of the word cover the elements or objects listed after the word and their equivalents, without excluding other elements or objects. "Connecting" or "connected" and similar words are not limited to physical or mechanical connections, but can include electrical connections, whether direct or indirect. "Up", "down", "left", "right" and the like are only used to represent relative positional relationships. When the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0036] In the manufacturing process of lithium-ion batteries, the battery cells discharged from the stacking machine or winding machine are generally transported through the transportation line to the welding machine in the subsequent section for subsequent operations. Limited by the battery cell process requirements, the unloading end of the winding machine or stacking machine mostly adopts the technology of transporting single-layer battery cells with single-layer pallets, and the unloading is also single-layer unloading, which results in the transportation efficiency of the battery cells being far lower than the efficiency of the subsequent welding machine. With the gradual increase in demand, the efficiency of single-layer transportation of battery cells has become increasingly difficult to meet production capacity requirements. How to improve the transportation efficiency of battery cells is an urgent problem to be solved in the industry.

[0037] At present, since there are many technical points that need to be taken into account in the transportation process of battery cells on the logistics line and the process of transferring battery cells through grippers, the current way to improve the efficiency of battery cell transfer is still based on increasing the size of the pallet, thereby increasing the number of single-layer battery cells that can be placed in each pallet, thereby improving the transportation capacity of a single pallet.

[0038] However, increasing the size of the pallet means that the size of the logistics line will also increase. The size of the material buffer components and other related components of each machine will also increase accordingly, occupying the factory space, making the production line bloated and causing a lot of waste of manpower, material resources and space. In addition, when transporting batteries, the current pallets use tension springs to tighten, and the tension springs are prone to foreign matter iron powder falling during movement, which affects the performance of the transported batteries and leads to defects during battery transportation.

[0039] Therefore, how to solve the problems of low efficiency and foreign matter falling when transporting battery cells has become an important technical problem to be solved by those skilled in the art.

[0040] Based on this, the present application provides a battery cell transfer tray and a battery cell transfer device. The battery cell transfer tray can support multiple battery cells to be transferred, so that multiple battery cells to be transferred can be transferred at the same time, thereby improving the efficiency of transferring battery cells. In addition, the battery cells to be transferred on the tray do not need to be tightened and fixed by tension springs, ensuring that the battery cell performance will not be affected by foreign objects falling during storage and transportation.

[0041] Specifically, see Figure 1 , Figure 1 The first exemplary structural schematic diagram of the battery cell transfer tray 1 is shown. The battery cell transfer tray 1 includes a plurality of sub-trays 11 spaced apart along the vertical direction, each sub-tray 11 includes at least two first support members 1111 spaced apart along the horizontal direction, each first support member 1111 is used to support a battery cell 3 to be transferred, and a clamping interval 113 is provided between two adjacent first support members 1111.

[0042] Specifically, the battery cell transfer tray 1 includes a plurality of sub-trays 11 spaced apart along the vertical direction, and the plurality of sub-trays 11 can be fixedly connected or detachably connected by connecting members. Exemplarily, the battery cell transfer tray 1 includes a plurality of columns 12, each of which is arranged along the vertical direction and connected to the plurality of sub-trays 11, so that the plurality of vertically arranged columns 12 can connect the plurality of sub-trays 11 spaced apart along the vertical direction together. Exemplarily, the columns 12 and the plurality of sub-trays 11 can be fixedly connected by welding, or detachably connected by bolting, and the specific connection method is not limited, as long as the columns 12 can connect the plurality of sub-trays 11 together.

[0043] Furthermore, a plurality of upright posts 12 are respectively located on two opposite sides of the sub-tray 11 to fix the plurality of sub-trays 11 from both sides, thereby increasing the stability of the entire battery cell transfer tray 1 .

[0044] Each sub-tray 11 includes at least two first support members 1111 spaced apart along the horizontal direction, and each first support member 1111 is used to support a battery cell 3 to be transferred, so that each sub-tray 11 can support at least two battery cells 3 to be transferred at the same time, and then multiple sub-trays 11 can support multiple battery cells 3 to be transferred at the same time.

[0045] Exemplarily, the battery cell transfer tray 1 includes five sub-trays 11 spaced apart in the vertical direction, each sub-tray 11 can support three battery cells 3 to be transferred, so one battery cell transfer tray 1 can simultaneously support 15 battery cells 3 to be transferred. Compared with the existing single tray, without increasing the size of the tray, the battery cell transfer tray 1 of the present application can greatly increase the number of battery cells 3 to be transferred that can be supported, thereby improving the efficiency of battery cell transfer.

[0046] A clamping gap 113 is provided between two adjacent first support members 1111. The clamping gap 113 allows the claws of the battery cell clamping device to extend into and clamp the battery cell 3 to be transported, so that at least two battery cells 3 to be transported on each sub-tray 11 can be transported at the same time, thereby improving the efficiency of battery cell transportation.

[0047] In the present application, the battery cell transfer tray 1 includes a plurality of sub-trays 11 spaced apart along the vertical direction, each sub-tray 11 includes at least two first support members 1111 spaced apart along the horizontal direction, each first support member 1111 is used to support a battery cell 3 to be transferred, so that the battery cell transfer tray can support a plurality of battery cells 3 to be transferred at the same time, and a clamping interval 113 is provided between adjacent first support members 1111, and the clamping interval 113 allows the transfer clamp to clamp the battery cell 3 to be transferred, thereby allowing a plurality of battery cells 3 to be transferred to be transferred at the same time, thereby improving the efficiency of battery cell transfer, and the tray and the first support member 1111 do not need to be tightened and fixed by tension springs, to ensure that the battery cell performance is not affected by the falling of foreign objects during storage and transfer.

[0048] In some embodiments, see Figure 2 and Figure 3 , Figure 2 A partial enlarged schematic diagram of the battery cell transfer tray 1 is shown. Figure 3 Shows Figure 2 The partial enlarged schematic diagram of C in the figure. Figure 2 and Figure 3 As shown, a second support member 1112 is disposed at intervals on two opposite sides of each first support member 1111 , and a clamping interval 113 is formed between the second support member 1112 and the first support member 1111 .

[0049] Specifically, there is a clamping gap between each second support member 1112 and the first support member 1111, and the clamping gap provides a space for the claws of the battery cell transport fixture 2 to extend into. In this way, the first support member 1111 and the second support member 1112 are used to support the battery cells 3 to be transported at the same time, thereby improving the storage stability of the battery cells 3 to be transported. At the same time, the clamping gap between the first support member 1111 and the second support member 1112 allows the claws of the battery cell transport fixture 2 to extend into the gap. The extended claws can clamp the battery cells 3 to be transported above the first support member 1111 and the second support member 1112 and transfer the battery cells 3 to be transported to the target position.

[0050] In some embodiments, see Figure 1 As shown, the first support member 1111 and the second support members 1112 located on both sides of the first support member 1111 form a support assembly 111, and the battery cell transport tray 1 also includes a first limit member 112 and a second limit member 116. The first limit member 112 is arranged in the first direction (i.e. Figure 1The second stopper 116 is disposed on both sides of the second direction (i.e. Figure 1 On both sides of the direction shown in B in the figure), wherein the first direction and the second direction are perpendicular to each other, and a plane formed by the intersection of the first direction and the second direction is parallel to the plane where the sub-tray 11 is located.

[0051] Specifically, each supporting assembly 111 is used to support a battery cell 3 to be transported.

[0052] The first limiting members 112 are disposed on both sides of each supporting assembly 111 in the first direction, and are used to limit the position of the battery cells 3 to be transported from both sides in the first direction to prevent the battery cells 3 to be transported from being offset from the first direction.

[0053] The second stoppers 116 are disposed on both sides of each supporting assembly 111 in the second direction, and are used to limit the position of the battery cells 3 to be transported from both sides in the second direction, so as to prevent the battery cells 3 to be transported from being deviated from the second direction, and further prevent the battery cells 3 to be transported from being moved out of the edge of the sub-tray 11. The edge refers to the position close to the outer edge of the sub-tray 11.

[0054] The first limiting member 112 and the second limiting member 116 are used to limit the battery cell 3 to be transported, so as to ensure that the battery cell 3 to be transported can be stably supported on the support assembly 111, and its position will not move arbitrarily, thereby ensuring the stability and transport efficiency of the battery cell 3 to be transported. If the position of the battery cell 3 to be transported moves arbitrarily, the battery cell 3 to be transported may not be effectively supported by the support assembly 111, thereby causing damage to the battery cell 3 to be transported, or affecting the efficiency of clamping and transporting the battery cell 3 to be transported.

[0055] In some embodiments, see Figure 1 and Figure 4 , Figure 4 A first side view of the cell transport tray 1 is shown. Figure 1 and Figure 4 As shown, the first stopper 112 includes a first stopper 112 along a first direction (such as Figure 1 A direction (as shown in FIG. 1 ), each of the first limit groups 1121 includes a plurality of first limit groups 1121 spaced apart from each other along the second direction (as shown in FIG. 1 ). Figure 1 A plurality of first limiting portions 11211 are arranged at intervals in the direction B as shown, wherein the first direction and the second direction are perpendicular to each other, and a plane formed by the intersection of the first direction and the second direction is parallel to the plane where the sub-tray 11 is located.

[0056] Specifically, the first direction and the second direction are perpendicular to each other, and the plane formed by the intersection of the first direction and the second direction is parallel to the plane where the sub-tray 11 is located, that is, the first direction can be the length direction of the sub-tray 11, and the second direction can be the width direction of the sub-tray 11, or the first direction can be the width direction of the sub-tray 11, and the second direction can be the length direction of the sub-tray 11.

[0057] A first limiting group 1121 is disposed on both sides of each supporting component 111 , so that the first limiting groups 1121 on both sides can limit the battery cells 3 to be transported on the supporting component 111 .

[0058] The first limiting group 1121 includes a plurality of positions along the second direction (eg Figure 1 The plurality of first limiting portions 11211 are arranged at intervals in the direction B shown in the figure. The plurality of first limiting portions 11211 can limit the battery cell 3 to be transported from various positions, ensuring that each position of the battery cell 3 to be transported can be limited without deviation.

[0059] Furthermore, the first limiting portion 11211 can be made of a soft material such as a rubber material, so that the first limiting portion 11211 can not only limit the battery cell 3 to be transported, but also ensure that the first limiting portion 11211 does not cause damage to the battery cell 3 to be transported.

[0060] Furthermore, the portion of the first limiting portion 11211 close to the battery cell 3 to be transported is an arc-shaped structure, so as to further ensure that the first limiting portion 11211 will not cause damage to the battery cell 3 to be transported.

[0061] In some embodiments, see Figure 1 , Figure 4 and Figure 5 , Figure 5 A second side view of the cell transport tray 1 is shown. Figure 1 , Figure 4 and Figure 5 As shown, the second stopper 116 includes a Figure 1 The first limit group 1121 and the support assembly 111 are located between the two second limit groups 1161, and each second limit group 1161 includes a first limit group 1121 and a second limit group 1161 along the first direction (such as Figure 1 A plurality of second limiting portions 11611 are spaced apart from each other in the direction A shown in the figure, and each second limiting portion 11611 is connected to at least one second supporting member 1112.

[0062] Specifically, the second stopper 116 includes a Figure 1Two second limiting groups 1161 are spaced apart in the direction B as shown, the first limiting group 1121 and the supporting assembly 111 are both located between the two second limiting groups 1161, and the second limiting member 116 is used to further limit the battery cell 3 to be transported which is supported by the supporting assembly 111 and limited by the first limiting group 1121.

[0063] Each second limit set 1161 includes a plurality of Figure 1 Multiple second limiting portions 11611 are arranged at intervals (in the direction A shown), so that the multiple second limiting portions 11611 can respectively limit the battery cells 3 to be transferred on the multiple supported components 111 arranged at intervals, and prevent the battery cells 3 to be transferred from moving out from the two edges of the sub-tray 11.

[0064] Continue to see Figure 3 As shown, each second limiting portion 11611 is connected to at least one second support member 1112, so that the second limiting portion 11611 can limit the end of the battery cell 3 to be transferred located on the second support member 1112, ensuring that the battery cell 3 to be transferred can be limited in all directions and the position of the battery cell 3 to be transferred will not change arbitrarily.

[0065] Furthermore, each second limiting portion 11611 is connected to two adjacent second support members 1112, and the two adjacent second support members 1112 respectively belong to two adjacent support assemblies 111. In this way, one second limiting portion 11611 can limit the ends of the battery cells 3 to be transported on the two support assemblies 111 at the same time, and the number of the second limiting portions 11611 can be reduced while ensuring the limiting effect, thereby reducing the manufacturing cost.

[0066] Furthermore, the second limiting portion 11611 can be made of a soft material such as a rubber material, so that the second limiting portion 11611 can not only limit the battery cell 3 to be transported, but also ensure that the second limiting portion 11611 does not cause damage to the battery cell 3 to be transported.

[0067] Furthermore, the portion of the second limiting portion 11611 close to the battery cell 3 to be transported is an arc-shaped structure, so as to further ensure that the second limiting portion 11611 will not cause damage to the battery cell 3 to be transported.

[0068] In some embodiments, the thickness of the first limiting member 112 and the second limiting member 116 are both greater than the thickness of the supporting assembly 111 , and the thickness direction is perpendicular to the direction of the sub-tray 11 .

[0069] Specifically, see Figure 3, the thickness of each first limiting portion 11211 in the first limiting member 112 is greater than the thickness of the supporting assembly 111, that is, the thickness of each first limiting portion 11211 in the first limiting member 112 is greater than the thickness of the first supporting member 1111 and the second supporting member 1112. The thickness of each second limiting portion 11611 in the second limiting member 116 is greater than the thickness of the supporting assembly 111, that is, the thickness of each second limiting portion 11611 in the second limiting member 116 is greater than the thickness of the first supporting member 1111 and the second supporting member 1112.

[0070] In this way, the first limiting member 112 and the second limiting member 116 can limit the battery cell 3 to be transferred in all directions to ensure that the position of the battery cell 3 to be transferred will not be offset.

[0071] In some embodiments, see Figure 1 Each sub-tray 11 includes a bottom plate 115, and the support assembly 111, the first stopper 112, and the second stopper 116 are all located on the bottom plate 115. The arrangement of the bottom plate 115 can make the battery cells 3 to be transported on each sub-tray 11 independent of each other, and prevent dust from crossing between the battery cells 3 to be transported.

[0072] The present application also provides a battery cell transport device, see Figure 6 , Figure 6 The schematic diagram of the exemplary structure of the battery cell transfer device is shown. The battery cell transfer device comprises a battery cell transfer tray 1 and a battery cell transfer fixture 2 of any of the above embodiments, wherein the battery cell transfer fixture 2 is used to clamp the battery cell 3 to be transferred located in the battery cell transfer tray 1 and transfer the battery cell 3 to be transferred to a target location.

[0073] Figure 7 shows an exemplary structural schematic diagram of a battery cell transport fixture 2, Figure 8 An exemplary structural schematic diagram of the clamping mechanism of the battery cell transport clamp 2 is shown.

[0074] In some embodiments, Figure 7 and Figure 8 As shown, the battery cell transport fixture 2 includes a driving mechanism 22 and a clamping mechanism 21. The clamping mechanism 21 includes a fixing plate 211. The fixing plate 211 has a Figure 8 At least two clamping components 212 are arranged at intervals in the D direction as shown, and the at least two clamping components 212 correspond one-to-one to at least two supporting components 111. The clamping components 212 are used to clamp the battery cells 3 to be transported on the corresponding supporting components 111.

[0075] Specifically, the driving mechanism 22 can drive the clamping mechanism 21 to move up, down, left, and right to flexibly adjust the position of the clamping mechanism 21, so that the clamping mechanism 21 can clamp the battery cell 3 to be transported in the battery cell transport tray 1 and transport the battery cell 3 to the target position. Exemplarily, the driving structure can be a robotic arm.

[0076] Continue to see Figure 8 Each clamping assembly 212 includes two clamping portions 2121 spaced apart in the horizontal direction. The two clamping portions 2121 correspond one-to-one to two clamping intervals 113 on both sides of a first support member 1111. The two clamping portions 2121 can extend into the two clamping intervals 113 simultaneously and separately.

[0077] Furthermore, within the same support component 111, clamping gaps are provided between the first support member 1111 and the second support members 1112 located on both sides thereof, and the two clamping portions 2121 of the clamping component 212 corresponding to the support component 111 can simultaneously and separately extend into the two clamping gaps to clamp the battery cells 3 to be transported located above the support component 111.

[0078] Fig. 9 21 shows a schematic diagram of the structure of the clamping portion 2121. In some embodiments, continue to refer to Figure 8 and Fig. 9 As shown, each clamping portion 2121 includes a plurality of Figure 8 The first clamp 21211 and the second clamp 21212 are spaced apart in the direction E shown in the figure. When the clamping portion 2121 extends into the corresponding clamping interval 113, the first clamp 21211 and the second clamp 21212 are respectively located on both sides of the battery cell 3 to be transported, and the first clamp 21211 can move relative to the second clamp 21212 so that the first clamp 21211 and the second clamp 21212 clamp or release the battery cell 3 to be transported.

[0079] Specifically, Fig.10 As shown, Fig.10 The side view of the battery cell transfer tray 1 with the battery cell 3 to be transferred is shown. When the clamping portion 2121 extends into the corresponding clamping interval 113, the first clamping jaw 21211 is located above the battery cell 3 to be transferred, and the second clamping jaw 21212 is located below the battery cell 3 to be transferred. The first clamping jaw 21211 can move relative to the second clamping jaw 21212, so that the first clamping jaw 21211 and the second clamping jaw 21212 can clamp or release the battery cell 3 to be transferred.

[0080] Fig.11 A side view of the clamping portion 2121 is shown. In some embodiments, see Fig.11As shown, a first clamping block 2123 is provided on the side of the first clamping jaw 21211 close to the second clamping jaw 21212, and a second clamping block 2122 is provided on the side of the second clamping jaw 21212 close to the first clamping jaw 21211. The first clamping block 2123 and the second clamping block 2122 are arranged relative to each other and / or staggered. In this way, the cooperation between the first clamping block 2123 and the second clamping block 2122 can enable the first clamping jaw 21211 and the second clamping jaw 21212 to better clamp the battery cell 3 to be transported.

[0081] Furthermore, the first clamping block 2123 and the second clamping block 2122 are made of soft materials such as rubber materials. On the one hand, the first clamping block 2123 and the second clamping block 2122 made of rubber materials have greater surface friction and can better clamp the battery cell 3 to be transported. On the other hand, the first clamping block 2123 and the second clamping block 2122 made of rubber materials can avoid damage to the battery cell 3 to be transported.

[0082] Furthermore, a plurality of openings 2124 are formed on the first clamping block 2123 and the second clamping block 2122 to reduce the weight of the first clamping jaw 21211 and the second clamping jaw 21212 while clamping the battery cell 3 to be transported, thereby facilitating practical operation.

[0083] Fig.12 A partial schematic diagram of the gripping assembly 212 is shown. In some embodiments, see Fig.11 and Fig.12 As shown, each clamping assembly 212 also includes a driving part 2125, a moving part 2126 and a fixed part 2127 which are connected in sequence from top to bottom, the first clamping jaw 21211 is connected to the moving part 2126, and the second clamping jaw 21212 is connected to the fixed part 2127. The moving part 2126 can move relative to the fixed part 2127 under the action of the driving part 2125, so that the first clamping jaw 21211 moves relative to the second clamping jaw 21212.

[0084] Specifically, the fixing portion 2127 includes a base 21271 and a monorail 21272 located on the base 21271. A second through hole 21273 is formed on the base 21271, and one end of the second clamping jaw 21212 extends into the second through hole 21273 and is fixed to the base 21271. Exemplarily, the end of the second clamping jaw 21212 is fixed to the base 21271 by a bolt, and one end of the bolt passes through the base 21271 and abuts or is threadedly connected to the end of the second clamping jaw 21212 located in the second through hole 21273, so as to fix the second clamping jaw 21212 and the base 21271.

[0085] The moving part 2126 includes a slider 21261 and reinforcement blocks 21262 fixed on both sides of the slider 21261. The slider 21261 is slidably matched with the monorail 21272. The reinforcement blocks 21262 reinforce and limit the slider 21261 from both sides, preventing the slider 21261 from deviating from the monorail 21272 during the sliding process, and ensuring the sliding accuracy of the slider 21261.

[0086] Each reinforcement block 21262 has a first through hole 21263, and one end of the first clamping jaw 21211 extends into the first through hole 21263 and is fixed to the reinforcement block 21262. Exemplarily, the end of the first clamping jaw 21211 is fixed to the reinforcement block 21262 by a bolt, and one end of the bolt passes through the reinforcement block 21262 and abuts or is threadedly connected to the end of the first clamping jaw 21211 located in the first through hole 21263, so as to fix the first clamping jaw 21211 and the reinforcement block 21262.

[0087] The driving part 2125 is fixed to the slider 21261, and the driving part 2125 can drive the slider 21261 to move along the monorail 21272, so that the first clamping jaw 21211 moves relative to the second clamping jaw 21212. Exemplarily, the driving part 2125 can be a driving motor or a cylinder.

[0088] During specific implementation, there is a large gap between the first clamping jaw 21211 and the second clamping jaw 21212 of the battery cell transporting clamp 2 to facilitate insertion into the tray.

[0089] The battery cell 3 to be transported is placed on the support assembly 111, and the first limiter 112 and the second limiter 116 limit the battery cell 3 to be transported. Then, the driving mechanism 22 of the battery cell transport fixture 2 drives the clamping mechanism 21 to move toward the direction close to the battery cell transport tray 1, so that each clamping assembly 212 corresponds to a support assembly 111, and the two clamping parts 2121 of the clamping assembly 212 can simultaneously and respectively extend into the two clamping intervals of the support assembly 111, and the first clamping jaw 21211 is located above the battery cell 3 to be transported, and the second clamping jaw 21212 is located below the battery cell 3 to be transported.

[0090] At this time, the driving part 2125 is started, so that the driving part 2125 drives the moving part 2126 to move towards the direction close to the fixed part 2127, and then the first clamping jaw 21211 moves towards the direction close to the second clamping jaw 21212, so that the first clamping jaw 21211 and the second clamping jaw 21212 can clamp the battery cell 3 to be transported.

[0091] After the first clamp 21211 and the second clamp 21212 clamp the battery cell 3 to be transported, the driving mechanism 22 of the battery cell transport fixture 2 drives the clamping mechanism 21 to move away from the battery cell transport tray 1, so that the first clamp 21211 and the second clamp 21212 move out of the clamping interval, and then the driving mechanism 22 continues to drive the clamping mechanism 21 to move to the target position.

[0092] Finally, start the driving part 2125 so that the driving part 2125 drives the moving part 2126 to move away from the fixed part 2127, and then the first clamp 21211 moves away from the second clamp 21212, so that the first clamp 21211 and the second clamp 21212 can release the battery cell 3 to be transported, and then steadily place the battery cell 3 to be transported at the target position, and drive the second clamp 21212 to be pulled out to leave the battery cell 3 to be transported, thereby completing the transportation of the battery cell 3 to be transported.

[0093] In the present application, there are multiple support components 111 on each sub-tray 11, and the multiple support components 111 can support multiple battery cells 3 to be transported. There are also multiple clamping components 212 of the battery cell transport fixture 2, so that the multiple clamping components 212 can simultaneously clamp and transport multiple battery cells 3 to be transported placed in a sub-tray 11, greatly improving the transport efficiency.

[0094] After transferring multiple battery cells 3 to be transferred on a sub-tray 11, the battery cell transfer clamp 2 is repeatedly driven to transfer multiple battery cells 3 to be transferred on the next sub-tray 11 again, which greatly improves the transfer efficiency.

[0095] In the present application, the purpose of transporting multiple layers of battery cells on a single pallet is achieved by setting up multiple stacked sub-pallets 11, thereby improving the transportation efficiency of the logistics line, abandoning the drawback of increasing the transportation capacity of a single pallet by increasing the plane size, and adopting multi-layer stacking technology to achieve cost reduction and efficiency improvement. The multi-layer stacking transportation technology of battery cells also alleviates the bloated problem of the caching mechanism between machines, thereby reducing the manufacturing cost of the entire production line from another dimension.
