The extension dimension of the sorting device in the vertical direction along the sorting direction is widened, the extension dimension of the sorting device in the sorting direction is reduced, and the layout space of the system is further reduced, so that the equipment cost and maintenance cost are reduced. In addition, due to the widening of the extension dimension of the sorting device in the vertical direction along the sorting direction, the sorting efficiency of the battery cells is improved.

[0034] In some embodiments, the sorting device further includes a transport mechanism and a pairing mechanism. The pairing mechanism is used to screen out battery cells that match the target type, and the transport mechanism is used to continuously arrange multiple battery cells of the same target type.

It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0060] Currently, the packaging equipment used in the power battery packaging process usually includes a roller line, which transports the battery cells stacked on pallets to the discharge position. This occupies a large area and requires a lot of equipment and maintenance costs.

[0061] To solve the above technical problems, an embodiment of the present application provides a battery cell packaging system, which adopts a transfer robot to replace the existing roller line to achieve miniaturization of battery cell packaging equipment, which is conducive to reducing equipment investment and maintenance costs.

[0062] The technical solutions described in the embodiments of this application are applicable to battery cell packaging systems, methods, and computer-readable storage media. The battery cell packaging systems, methods, and computer-readable storage media disclosed in this application can be used in the fields of lithium-ion secondary batteries, as well as sodium-ion secondary batteries, and can be specifically configured as needed.

[0063] The present application is described in detail below with reference to the accompanying drawings and embodiments.

[0064] See also Figure 1 , Figure 1 Schematic diagram of the structure of the battery cell packaging system provided in the embodiment of the present application.

[0065] See Figure 1 , an embodiment of the present application provides a battery monomer packaging system 1000, including a feeding device 100, a sorting component 200, a manipulator 300 and a transfer robot 401. Among them, the feeding device 100 is configured to receive the battery monomer 2000 and obtain the type information of the battery monomer 2000. The sorting component 200 is configured to receive the battery monomer 2000 transferred from the feeding device 100, and to divert multiple battery monomers 2000 to different transfer channels based on the type information. The manipulator 300 is configured to grab the battery monomer 2000 on the transfer channel and transfer the grabbed battery monomer 2000 to the pallet 500. The transfer robot 401 is configured to receive a control instruction and transfer the pallet 500 to be transferred.

[0066] Among them, the battery cell packaging system 1000 refers to a combined equipment system that performs multiple processes such as sorting, stacking, and transferring a large number of battery cells 2000. A battery cell 2000 refers to the smallest unit that makes up a battery. In some embodiments, a battery cell 2000 includes a positive electrode sheet, a negative electrode sheet, and a separator provided between the positive electrode sheet and the negative electrode sheet. Since the types of battery cells 2000 in the production line are in dynamic change, the embodiments of the present application can automatically switch the type of battery cells 2000 entering the sorting component 200 based on the acquired type information of the battery cells 2000, so that the sorting component 2000 can operate efficiently for a long time, thereby improving the operating efficiency of the battery cell packaging system 1000. In some embodiments, the discharge port of the feeding device 100 is provided with a barcode scanner for scanning the battery cells 2000 to obtain the type information of the battery cells 2000. In some embodiments, the sorting component 200 includes multiple transfer channels for receiving battery cells 2000. In some embodiments, the transfer channel of the sorting component 200 is set within the grasping range of the manipulator 300. In the embodiment of the present application, the multiple battery cells 2000 transferred to the same pallet 500 should in principle be of the same type. The transfer robot 401 refers to a robot with an automatic guidance function, which can travel along a set guide path and has various transfer and / or loading functions. The number of transfer robots 401 can be one or more, and can be set according to specific needs. In some embodiments, the transfer robot 401 has a fixed standby position. When no control command is received, the transfer robot 401 is stored in the standby position. When a control command is received, the transfer robot 401 leaves the standby position and is transferred to the pallet stacking area of ​​​​the pallet 500. In some embodiments, there can be multiple standby positions to facilitate the dispatch of multiple transfer robots to transfer the pallets 500 to be transferred when multiple pallets 500 are to be transferred. In some embodiments, the transferred pallets 500 can be stored in an area adjacent to the battery cell packaging system 1000 to improve the transfer efficiency. In some embodiments, the transfer robot 401 refers to an automated guided vehicle (AGV).

[0067] In an embodiment of the present application, a battery cell packaging system 1000 is provided, including a transfer robot 401. The transfer robot 401 is used to transfer the battery cells 2000 to be transferred. Compared to setting up fixed transfer equipment, this reduces the system's layout space, achieves miniaturization of the battery cell packaging system 1000, and reduces equipment and maintenance costs. Furthermore, the transfer robot 401's standardized transfer reduces the possibility of damage to the battery cells 2000. Furthermore, the transfer robot 401's flexible and efficient transfer reduces manpower and time consumption, improves transfer efficiency, and contributes to increased production line profits.

[0068] In some embodiments, the transfer robot 401 is further configured to: receive control instructions, obtain an empty pallet 500, transfer the obtained empty pallet 500 to the palletizing area AA, and place it in the pallet installation position of the palletizing area AA.

[0069] Among them, palletizing area AA refers to the palletizing area of ​​​​the pallet 500. In some embodiments, multiple pallets 500 are stacked and palletized in palletizing area AA. In some embodiments, there are multiple palletizing areas AA, each palletizing area AA is used to receive multiple battery cells 2000 of a single type. In some embodiments, multiple palletizing areas AA are located within the grasping range of the manipulator. In some embodiments, empty pallets 500 can be set in an empty pallet storage area, and the empty pallet storage area can be set adjacent to the area where the battery cell packaging system 1000 is located to reduce the transfer path length of the transfer robot 401.

[0070] In an embodiment of the present application, the transfer robot 401 also has the function of replenishing empty pallets 500, so that when the pallets 500 to be transferred are transferred out, the empty pallets 500 can be replenished in time, which is beneficial to improving the transfer efficiency of the battery cells 2000.

[0071] In some embodiments, the battery cell packaging system 1000 includes at least one transfer robot group 410, which includes a first transfer robot 411 and a second transfer robot 412. The first transfer robot 411 is configured to receive a first control instruction and transfer a pallet 500 to be transferred. The second transfer robot 412 is configured to receive a second control instruction, obtain an empty pallet 500, follow the first transfer robot 411, and place the empty pallet 500 on the pallet mounting position in palletizing area AA after the first transfer robot 411 transfers the pallet 500 to be transferred.

[0072] The transfer robot group 410 is used to improve the efficiency of pallet 500 replacement. In some embodiments, the activation of the first transfer robot 411 and the second transfer robot 412 can be controlled simultaneously. In some embodiments, the first transfer robot 411 can be activated first, followed by the second transfer robot 412. In some embodiments, the second transfer robot 412 can be activated first, followed by the first transfer robot 411. In some embodiments, the second transfer robot 412 can be controlled to pre-acquire an empty pallet 500. After receiving the control command, the two transfer robots can be activated simultaneously. The second transfer robot 412, carrying the empty pallet 500, follows the first transfer robot 411. After the first transfer robot 411 transfers the pallet 500 to be transferred, it places the empty pallet 500 on the pallet mounting position in palletizing area AA. In some embodiments, the second transfer robot 412 can be controlled to be pre-positioned in the standby position of the first transfer robot 411, or it can be controlled to be pre-positioned in palletizing area AA where the empty pallet 500 to be transferred is located. In some embodiments, multiple transfer robot groups 410 can be provided to improve transfer efficiency. In some embodiments, the transfer robot group 410 may include a plurality of first transfer robots 411 and a plurality of second transfer robots 412 to improve transfer efficiency.

[0073] In an embodiment of the present application, by setting up the transfer robot group 410, when one transfer robot 401 takes away a pallet 500 containing battery cells 2000, another transfer robot 401 can replace the empty pallet in time, thereby improving the replacement efficiency of the pallet 500 and the transfer efficiency of the battery cells 2000.

[0074] See also Figure 2 , Figure 2 This is another structural schematic diagram of the battery cell packaging system provided in an embodiment of the present application.

[0075] In some embodiments, see Figure 2 The battery cell packaging system 1000 also includes a working condition control module 600 and a transfer control module 700. The working condition control module 600 is configured to communicate with the feeding device 100, the sorting assembly 200, and the manipulator 300. The transfer control module 700 is configured to communicate with the transfer robot 401 and the working condition control module 600. The transfer control module 700 is configured to receive data information transmitted by the working condition control module 600 and issue control instructions to control the transfer robot 401.

[0076] In an embodiment of the present application, by setting up the working condition control module 600 and the transfer control module 700, the transfer robot 401 can transfer the battery cell 2000, and thereby realize the miniaturization of the battery cell packaging system 1000 formed by the transfer robot 401, the feeding device 100, the sorting component 200 and the manipulator 300, thereby reducing the equipment cost and maintenance cost.

[0077] In some embodiments, please refer to Figure 1 and Figure 2 The operating condition control module 600 is configured to: transmit information that the tray 500 is full of battery cells 2000; or, transmit information that the number of battery cells 2000 carried on the tray 500 has reached a threshold; or, transmit information that the target type of the battery cells 2000 has changed.

[0078] Among them, a full tray means that the pallet 500 carries the maximum number of battery cells 2000. The threshold value refers to the preset number of battery cells 2000 carried on the pallet 500. The working condition control module 600 is configured to transmit information that the number of battery cells 2000 carried on the pallet 500 has reached the threshold value, so as to facilitate the early call of the transfer robot 401, so that the timing when the battery cells 2000 carried on the pallet 500 reaches a full tray is close to the timing when the transfer robot 401 is transferred to the stacking area AA, thereby improving the transfer efficiency. In some embodiments, a model can be established based on the historical data information of the battery cell 2000. When the pallet 500 carrying the battery cell 2000 is not full, the transfer robot 401 is notified in advance based on the historical data of the pallet discharge, and there is no need to wait until the pallet is full, which is conducive to improving the efficiency of transfer. The operating condition control module 600 is configured to transmit information that the target type of the battery cells 2000 has changed, so that according to the dynamic changes of the production line, the tray 500 containing the battery cells 2000 that no longer belong to the target type can be removed in time, so that the battery cells 2000 of the new target type can be transferred from the robot 300 to the empty tray 500.

[0079] In some embodiments, through the setting of the working condition control module 600, information about the battery cells 2000 carried by the pallet 500 or information about changes in the target type of the battery cells 2000 can be transmitted in a timely manner. The transfer control module 700 can issue control instructions to the transfer robot in a timely manner based on the acquired information, thereby improving the transfer efficiency of the battery cell packaging system 1000.

[0080] In some embodiments, please continue to refer to Figure 1 and Figure 2 , the operating condition control module 600 is configured to:

[0081] Obtaining type information of all battery cells 2000 entering the feeding device 100, and counting the top N types of all battery cells 2000 to determine them as target types;

[0082] Count the number ratio of battery cells 2000 of each target type;

[0083] When information is obtained that the number ratio of the battery cells 2000 of non-target types exceeds the number ratio of the battery cells 2000 of the target type, information is issued indicating that the target type of the battery cells 2000 has changed.

[0084] In some embodiments, a barcode scanner is provided at the outlet of the feed device 100. The barcode scanner scans the battery cells 2000 at the outlet to obtain the type information of all the battery cells 2000 entering the feed device 100. In some embodiments, the number of all the battery cells 2000 entering the feed device 100 and the number of the battery cells 2000 transported by the transport robot 401 are counted. Based on the difference between the two, the total number of battery cells 2000 in the battery cell packaging system 1000 can be obtained. Based on the proportion of the number of each type of battery cells 2000 in the battery cell packaging system 1000 to the total number, information on changes in the target type of the battery cells 2000 is promptly issued.

[0085] In the embodiment of the present application, the operating condition control module 600 can timely transmit information on changes in the target types of the battery cells 2000 in the battery cell packaging system 1000 based on information on changes in the types of the battery cells 2000 in the system.

[0086] See also Figure 3 , Figure 3 It is a structural schematic diagram of the sorting component provided in the embodiment of the present application.

[0087] In some embodiments, please refer to Figure 1 and Figure 3 The sorting component 200 provided in the embodiment of the present application includes a sorting device 210, and the sorting device 210 includes a first-level sorting mechanism 211, a second-level sorting mechanism 212 and a cache mechanism 213; the first-level sorting mechanism 211 is connected to the feeding device 100, and the second-level sorting mechanism 212 is connected to the first-level sorting mechanism 211; the first-level sorting mechanism 211 and the second-level sorting mechanism 212 include four-motor drives, and the cache mechanism 213 includes eight transfer channels. The first-level sorting mechanism 211 and the second-level sorting mechanism 212 divert multiple battery cells 2000 to different transfer channels based on type information.

[0088] Among them, in some embodiments, the primary material distribution mechanism 211 is configured to divert two target types of battery cells 2000 from a plurality of battery cells 2000. The secondary material distribution mechanism 212 is configured to divert the two target types of battery cells 2000 to different transfer channels, and enter the cache mechanism 213 through different transfer channels. The cache mechanism 213 is configured to receive and store a plurality of battery cells 2000 from the secondary material distribution mechanism 212, and reconcile the differences in the feeding rate and the discharging rate of the battery cells 2000. In some embodiments, among the eight transfer channels included in the cache mechanism 213, four adjacent ones are configured to receive battery cells 2000 of one target type, and the other four adjacent ones are configured to receive battery cells 2000 of another target type.

[0089] In the embodiment of the present application, the first-level material dividing mechanism 211 and the second-level material dividing mechanism 212 include four-motor drives, and the cache mechanism 213 includes eight transfer channels. The extension dimension of the sorting device 210 in the vertical direction along the sorting direction is widened, and the extension dimension of the sorting device 210 in the sorting direction is reduced, which further reduces the layout space of the system, reduces the equipment cost and maintenance cost, and due to the widening of the extension dimension of the sorting device 210 in the vertical direction along the sorting direction, the sorting efficiency of the battery cell 2000 is improved.

[0090] In some embodiments, please continue to refer to Figure 1 and Figure 3 The sorting device 210 provided in the embodiment of the present application also includes a transfer mechanism 214 and a pairing mechanism 215. The pairing mechanism 215 is used to screen out battery cells 2000 that match the target type, and the transfer mechanism 214 is used to continuously arrange multiple battery cells 2000 of the same target type.

[0091] In some embodiments, the transfer mechanism 214 is configured to transfer a plurality of battery cells 2000 of the same target type that are arranged in a row from the buffer mechanism 213 to the pairing mechanism 215. In some embodiments, the pairing mechanism 215 is configured to transfer the plurality of battery cells 2000 of the same target type as a whole to the robot 300. In some embodiments, the pairing mechanism 214 is equipped with a barcode scanner for scanning the battery cells 2000 to obtain the type information of the battery cells 2000. If a battery cell 2000 of a different type is present, the robot 300 will transfer the battery cell group. If the type information is correct, the robot 300 will palletize the battery cell group onto the corresponding tray 500.

[0092] In the embodiment of the present application, by setting up the transfer mechanism 214 and the pairing mechanism 215, multiple battery cells 2000 of the same target type are configured as multiple battery cell combinations, so that the robot 300 can grasp the battery cell combinations, thereby improving the unloading rate.

[0093] See also Figure 4 , Figure 4 This is another structural schematic diagram of the sorting component provided in an embodiment of the present application.

[0094] In some embodiments, please refer to Figure 1 、 Figure 3 and Figure 4 The sorting assembly 200 provided in the embodiment of the present application includes multiple sorting devices 210 and a transition mechanism 220. The transition mechanism 220 is used to connect the feeding device 100 or the primary sorting mechanism 211 of the sorting device 210, and is configured to divert battery cells 2000 to different sorting devices 210.

[0095] In some embodiments, the transition mechanism 220 is disposed on a side of the transition mechanism 220 away from the sorting device 210. In some embodiments, the sorting assembly 200 includes two sorting devices 210, which are arranged in parallel and spaced apart. The first sorting device 210 is used to sort out the first and second target types of battery cells 2000, and the second sorting device 210 is used to sort out the third and fourth target types of battery cells 2000. One end of the transition mechanism 220 is connected to the primary sorting mechanism 211 of the first sorting device 210, and the other end is connected to the primary sorting mechanism 211 of the second sorting device 210, and is used to receive the battery cells 2000 that have not entered the first sorting device 210, and allow the third and fourth target types of battery cells 2000 to enter the second sorting device 210.

[0096] In the embodiment of the present application, by disposing a plurality of sorting devices 210 and transition mechanisms 220 , the sorting assembly 200 can sort multiple target types of battery cells 2000 , thereby improving the sorting efficiency.

[0097] In some embodiments, please continue to refer to Figure 1 and Figure 4 The sorting assembly 200 provided in the embodiment of the present application further includes a manual handling mechanism 230 and an NG mechanism 240. The manual handling mechanism 230 is used to connect to the feeding device 100, the transition mechanism 220, or the primary sorting mechanism 211 of the sorting device 210. The manual handling mechanism 230 is configured to receive battery cells 2000 that have not been diverted to the sorting device 210. The NG mechanism 240 is configured to receive battery cells 2000 that do not match the target type.

[0098] In some embodiments, the NG mechanism 240 cooperates with the pairing mechanism 214 to receive battery cells 2000 that do not match the target type after being scanned by the pairing mechanism 214, and quickly transfers the sorted mismatched battery cells 2000, which is beneficial to improving the accuracy and efficiency of sorting.

[0099] In the embodiment of the present application, the setting of the manual processing mechanism 230 allows non-target type battery cells 2000 to be quickly received, and the setting of the NG mechanism 240 facilitates the rapid transfer of battery cells 2000 that do not match the target type, thereby improving the sorting efficiency.

[0100] In some embodiments, see Figure 1 The battery cell packaging system 1000 provided in an embodiment of the present application further includes a middle cap feeding mechanism 800, which is disposed on a side of the sorting assembly 200 near the robot arm 300. The middle cap feeding mechanism 800 is configured to hold multiple layers of middle caps. The top middle cap of the multiple layers is movably protruding from the middle caps of the other layers and is movable toward the robot arm 300.

[0101] The middle cover is positioned between two adjacent layers of battery cells 2000 stacked on the same tray 500, providing protection and cushioning for the adjacent layers. The middle cover feeding mechanism 800 is used to pre-store multiple middle covers, allowing the robot 300 to promptly transfer them to the top of a layer of battery cells 2000. In some embodiments, the middle cover feeding mechanism 800 includes a main structure, typically a shelf, upon which multiple layers of trays 500 are positioned, each carrying the middle covers. In embodiments of the present application, the top tray 500 is movably protruding from the main structure. In some embodiments, a guide rail structure is provided at the top of the main structure, allowing the top tray 500 to protrude from the main structure, allowing the top middle cover to move toward the robot 300, facilitating its grasping. In some embodiments, the middle covers are also supplemented by the transfer robot 401, reducing the need for fixed transfer equipment, simplifying the layout of the battery cell packaging system 1000, and reducing the difficulty of transfer.

[0102] In the embodiment of the present application, the middle cover feeding mechanism 800 is provided to shorten the distance to the robot 300, so that the robot 300 can quickly grasp the middle cover within its grasping range, thereby improving the stacking efficiency of the battery cells 2000.

[0103] In a specific embodiment, the working process of the battery cell packaging system 1000 provided in the embodiment of the present application is as follows:

[0104] The battery cells 2000 are input through the feeding device 100, and a barcode scanner is equipped at the discharge port of the feeding device 100 to identify the type of the battery cells 2000, and flow into the first-level sorting mechanism 211 of the first sorting device 210. The battery cells 2000 of the first target type and the second target type are diverted to the second-level sorting mechanism 212 of the first sorting device 210, and the battery cells 2000 of the first target type and the second target type are diverted to the cache mechanism 213 of the eight transfer channels in turn. When the cache mechanism 213 is full of 10 battery cells 2000, the transfer mechanism 214 is triggered to pair and arrange the 10 battery cells 2000. After the pairing is completed, the pairing mechanism 215 performs a second scan to confirm the type of the battery cell 2000. If other types of battery cells 2000 appear, the robot 300 grabs this column of battery cells 2000 and places them in the NG mechanism 240 to discharge unmatched battery cells 2000. If the information is correct, the robot 300 stacks the battery cells 2000 into the corresponding tray 500 .

[0105] The third target type of battery cells 2000, the fourth target type of battery cells 2000 and other types of battery cells 2000 in the first-level sorting mechanism 211 of the first sorting device 210 are shunted to the first-level sorting mechanism 211 of the second sorting device 210 through the transition mechanism 220, and then the first-level sorting mechanism 211 shunts the third and fourth target types of battery cells 2000 to the second-level sorting mechanism 212 of the second sorting device 210, and then the third and fourth target types of battery cells 2000 are shunted to the second-level sorting mechanism 212 of the second sorting device 210. Cells 2000 are sequentially distributed to the buffer mechanism 213 of the eight transfer channels. When the buffer mechanism 213 is full of 10 battery cells 2000, the transfer mechanism 214 is triggered to pair and arrange the 10 battery cells 2000. After pairing is complete, the pairing mechanism 215 performs a second scan to confirm the type of battery cells 2000. If a different type of battery cell 2000 is present, the robot 300 grabs the battery cells 2000 in that row and places them in the NG mechanism 240 to remove the mismatched battery cells 2000. If the information is correct, the robot 300 palletizes the battery cells 2000 onto the corresponding tray 500.

[0106] Other types of battery cells 2000 in the primary sorting mechanism 211 of the second sorting device 210 are discharged through the manual processing mechanism 230 for manual sorting and palletizing.

[0107] The transfer control module 700 receives information that the pallet 500 is full of battery cells 2000; or receives information that the number of battery cells 2000 carried on the pallet 500 has reached a threshold; or receives information that the target type of the battery cells 2000 has changed, and controls the transfer robot 401 to move to the stacking area of ​​the pallet 500 to be transferred, and transfers the pallet 500 to be transferred out.

[0108] During the operation of the production line, battery cells 2000 are generated in real time. The working condition control module 600 improves the formula of the battery cells 2000 in real time and realizes automatic switching. A model is established based on the historical data information of the battery cells 2000. When the tray 500 carrying the battery cells 2000 is not full, the transfer robot is notified in advance based on the historical data of the pallet discharge, realizing intelligent and flexible transfer.
