The following embodiments are used to illustrate the present application, but are not used to limit the scope of the present application.

[0047] Unless otherwise defined, all technical and scientific terms used in this application have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used in this application are only for the purpose of describing this embodiment and are not intended to limit this application.

[0049] If similar descriptions of "first / second" appear in the application documents, the following instructions are added. In the following description, the terms "first\second\third" involved are merely used to distinguish similar objects and do not represent a specific ordering of the objects. It can be understood that "first\second\third" can be interchanged in a specific order or sequence where permitted, so that the present embodiment described here can be implemented in an order other than that illustrated or described here.

[0050] In the embodiments of the present application, the term "and / or" is merely a description of the association relationship between associated objects, indicating that three relationships may exist. For example, object A and / or object B may represent three situations: object A exists alone, object A and object B exist at the same time, and object B exists alone.

[0051] At present, new energy batteries are more and more widely used in life and industry. New energy batteries are not only used in energy storage power systems such as hydropower, thermal power, wind power and solar power stations, but also widely used in electric vehicles such as electric bicycles, electric motorcycles, electric vehicles, and aerospace and other fields. With the continuous expansion of the application field of power batteries, the market demand is also constantly expanding. In the embodiment of the present application, the battery involved may be a battery cell. A battery cell refers to a basic unit that can realize the mutual conversion of chemical energy and electrical energy, which can be used to make a battery module or a battery pack, so as to supply power to an electrical device. A battery cell may be a secondary battery, which refers to a battery cell that can be used to activate the active material by charging after the battery cell is discharged. The battery cell may be a lithium ion battery, a sodium ion battery, a sodium lithium ion battery, a lithium metal battery, a sodium metal battery, a lithium sulfur battery, a magnesium ion battery, a nickel hydrogen battery, a nickel cadmium battery, a lead-acid battery, etc., and the embodiment of the present application is not limited to this.

[0052] In the embodiment of the present application, the battery may also be a single physical module including one or more battery cells to provide higher voltage and capacity. When there are multiple battery cells, the multiple battery cells are connected in series, in parallel or in hybrid connection through a busbar component.

[0053] In the related art, liquid injection is a key process in the production of lithium-ion batteries. The quality of the liquid injection results not only affects the battery performance, but also restricts the battery production efficiency. In the process of cell liquid injection, the cell after liquid injection is separated from the tray that carries the cell. The mechanical gripper needs to know which positions of the tray to be disassembled contain the cell, so as to grab the cell and separate the tray from the cell. Here, if the mechanical gripper cannot accurately know the specific position of the cell in the tray, it will lead to low efficiency and low accuracy in the process of separating the cell from the tray.

[0054] Based on the above technical problems, some embodiments of the present application provide a system and method for disassembling a battery cell, and the method for disassembling a battery cell includes: first, in response to the battery cell after liquid injection arriving at the disassembling station, the tray code of the tray is obtained; wherein the tray is used to carry the battery cell, and based on the tray code, the position index information of the battery cell in the tray is determined in the tray data table obtained by the code reading station; wherein the code reading station is the station before the disassembling station; then, based on the position index information and the tray code, the disassembling mechanism deployed at the disassembling station is controlled to separate the tray and the battery cell, so that the battery cell enters the next station in the liquid injection process. In this way, on the one hand, based on the tray code and the tray data table, the position index information of the battery cell in the tray is determined, that is, which positions in the tray have battery cells can be accurately known; on the other hand, based on the position index information, that is, the more specific battery cell position, the disassembling mechanism deployed at the disassembling station is controlled to separate the battery cell from the tray, thereby improving the efficiency and accuracy of separating the battery cell after liquid injection from the tray.

[0055] For the convenience of explanation, the following embodiments are described by taking a method for disassembling a battery cell provided in some embodiments of the present application as an example. The method for disassembling a battery cell is applied to a liquid injection host computer, see Figure 1 FIG. 1 is a flow chart of a method for disassembling a battery cell according to some embodiments of the present application. Figure 1 , the following combination Figure 1 The following instructions are given:

[0056] Step S101: in response to the battery cells after injection arriving at the tray depalletizing station, a tray code of the tray is obtained.

[0057] Wherein, the tray is used to carry the battery core.

[0058] In the embodiment of the present application, the liquid injection host computer may be an industrial computer (industrial control equipment); wherein the liquid injection host computer may include a processor and a memory. Here, the memory may be used to store relevant programs running on the processor, and at the same time, the processor may execute the method for disassembling the battery cell when running the program.

[0059] In the embodiment of the present application, the injection host computer can exchange data with the controller; wherein the controller can be: a programmable logic controller (PLC) and the like.

[0060] In the embodiment of the present application, the battery cell after liquid injection may refer to the battery cell after liquid injection once, or may refer to the battery cell after liquid injection twice, and the embodiment of the present application does not impose any limitation on this.

[0061] It should be noted that the primary liquid injection of the battery cell is carried out during the battery cell manufacturing process, and its purpose is to ensure the stability of the battery cell capacity and provide protection for the life of the battery cell; while the secondary liquid injection is carried out during the use of the battery cell, and its purpose is to maintain the consistency of the battery cell capacity and extend the service life of the battery cell.

[0062] In the embodiments of the present application, the battery cell may refer to a battery cell of any shape, such as a square battery cell, a round battery cell, etc. And the battery cell usually refers to a battery cell (Battery Cell), which is one of the basic units that constitute the battery. The battery cell is the core component of the battery, responsible for storing and releasing electrical energy. Here, the battery cell can be: a lithium-ion battery cell (Li-ion Cell), a lithium polymer battery cell (Li-polymer Cell), a nickel-metal hydride battery cell (NiMH Cell), etc. The embodiments of the present application do not impose any restrictions on the type of battery cell, and the specific selection can be made according to the actual application scenario.

[0063] In the embodiments of the present application, the battery cell is the core component of the battery pack. A battery pack usually contains multiple battery cells, which are combined together to provide the required power capacity and voltage. Among them, the battery pack refers to a device composed of multiple battery cells, which is designed to store electrical energy and provide power supply. The components of the battery pack include at least: battery cells, battery management system (Battery Management System, BMS), housing, connecting harness, connector and interface, etc. These components work together to combine the battery cells into a fully functional battery pack for various application scenarios. For example, the battery pack can be applied to electric vehicles, energy storage systems, portable electronic devices, solar energy systems, wind energy systems, emergency backup power supplies, power tools or electric bicycles, etc. The embodiments of the present application do not make any restrictions on this, and can be selected according to the actual application scenario.

[0064] In the embodiment of the present application, the tray removal station may be a station for separating the battery cell from the tray carrying the battery cell; wherein the tray removal station may be equipped with a gripping mechanism (mechanical gripper) for gripping the battery cell. Here, the gripping mechanism is a typical robot end effector, which is mainly used to perform operations such as gripping, carrying, placing, and releasing.

[0065] In the embodiment of the present application, the tray is used to carry the (filled) battery cells, that is, the battery cells that have entered the filling process and have been filled with liquid; wherein, a plurality of slots may be arranged on the tray, and the slots are used to hold a plurality of battery cells (batteries), and the battery cells held in the slots may perform related operations, such as filling, welding or welding detection, etc. At the same time, the corresponding shape and size settings of the plurality of slots arranged on the tray match the battery cells or batteries.

[0066] In the embodiment of the present application, the number of the card slots on the tray can be 8, 10, 32, etc. Here, the number of the card slots can be determined according to the actual battery cell filling requirements; there is no limitation on this in the embodiment of the present application.

[0067] In the embodiment of the present application, the battery cell after liquid injection arrives at the tray disassembly station, and the relevant battery cell transportation mechanism can transport the tray carrying the battery cell to the tray disassembly station. Here, the control system (controller) corresponding to the battery cell in the liquid injection process can also control the tray transportation so that the battery cell after liquid injection arrives at the tray disassembly station; or the controller can control the relevant grasping mechanism to grasp the battery cell after liquid injection from the previous station to the tray disassembly station.

[0068] In the embodiment of the present application, the number of battery cells after liquid injection can be one or more, and the embodiment of the present application does not impose any limitation on this.

[0069] In the embodiment of the present application, the pallet code may be in the form of a barcode, a QR code, etc., and the present application does not impose any limitation on this.

[0070] It should be noted that pallet codes are usually used in logistics, such as battery cell transportation management, to identify and track the battery cells it carries.

[0071] In the embodiment of the present application, the pallet code may be a mark on the pallet, or may be a pallet code associated with the pallet and stored inside the injection host computer.

[0072] In an embodiment of the present application, the liquid injection host computer can control the relevant scanning mechanism to scan the tray under the action of the read signal sent by the controller to obtain the tray code (barcode) of the tray.

[0073] In an embodiment of the present application, when the battery cells after liquid injection arrive at the tray depalletizing station, an image of the tray can be captured, and the tray code of the tray carrying the battery cells can be obtained by identifying the image obtained from the image capture.

[0074] It can be understood that through the above steps, the tray code of the tray carrying the battery cells is obtained, so as to provide a parameter basis for subsequently determining the specific positions of the battery cells in the tray based on the tray code, thereby improving the efficiency and accuracy of subsequent separation of the battery cells after injection from the tray.

[0075] Step S102: Based on the tray code, determine the position index information of the battery cell in the tray in the tray data table obtained by the code reading station.

[0076] Among them, the code reading station is the station before the disk disassembly station.

[0077] In the embodiment of the present application, the liquid injection host computer obtains the corresponding position index information from the previously known pallet data table based on the pallet code. The position index information may be generated when the battery cell is placed on the pallet, and the battery cell has been placed on the pallet before reaching the pallet removal station, so that the liquid injection host computer can obtain the position index information from the previously generated relevant data.

[0078] In the embodiment of the present application, the position index information corresponding to the battery cell in the tray refers to the position memory information of the battery cell in the tray; wherein the position index information can be represented by the slot number corresponding to the battery cell in the tray, etc.

[0079] In an embodiment of the present application, the pallet data table may be obtained by the liquid filling host computer performing corresponding data reading at the code reading station. During the liquid filling process, the battery cell is transported to the code reading station, the liquid filling station and the pallet disassembly station in sequence.

[0080] In the embodiment of the present application, the tray removal station and the code reading station can be adjacent or far away. For example, there are other stations in the middle, such as a testing station, a liquid injection station, etc. Here, the code reading station can be the first station of the battery cell entering the liquid injection process.

[0081] It should be noted that the pallet data table may include relevant information of multiple pallets. Here, the relevant information of each pallet may at least include: pallet code, position index information of the battery cells in the pallet, position mark of the pallet on the workstation, etc.; wherein the pallet code, position index information and position mark of each pallet correspond to each other one by one.

[0082] It can be understood that through the above steps, based on the obtained pallet code, the position index information of the battery cells carried by the pallet is obtained from the previously stored pallet data table. In this way, on the basis of being able to improve the efficiency of obtaining the position index information, parameter support is provided for the subsequent separation of the battery cells from the pallet.

[0083] Step S103: Based on the position index information and the tray code, control the tray removal mechanism deployed at the tray removal station to separate the tray and the battery cell, so that the battery cell enters the next station in the liquid injection process.

[0084] In an embodiment of the present application, after obtaining the position index information and the pallet code, the liquid injection host computer can, under the action of the controller, control the tray removal mechanism deployed at the tray removal station to separate the pallet and the battery cells, that is, to grab the battery cells from the pallet and move them to the next station.

[0085] It should be noted that the disassembly mechanism deployed on the disassembly station can be set corresponding to the battery cell on the disassembly station, and the present application embodiment does not impose any limitation on this. For example, the disassembly mechanism can be deployed directly above the disassembly station, or can be deployed on the side of the disassembly station and can be rotated at a preset angle to achieve the purpose of grabbing the battery cell on the disassembly station.

[0086] It should be noted that the number of battery cells that the tray removal mechanism grabs at one time can be determined according to actual needs, and the embodiments of the present application do not impose any limitation on this.

[0087] In the embodiment of the present application, the next station in the injection process can be an exit station, that is, a station for post-weighing, or a barcode scanning and verification station. The embodiment of the present application does not impose any limitation on this.

[0088] It can be understood that through the above scheme, first, in response to the battery cell after injection arriving at the tray removal station, the tray code of the tray carrying the battery cell is obtained, and based on the tray code, the position index information of the battery cell in the tray is determined in the tray data table obtained by the code reading station; wherein the code reading station is the station before the tray removal station; then, based on the position index information and the tray code, the tray removal mechanism deployed at the tray removal station is controlled to separate the tray and the battery cell, so that the battery cell enters the next station in the injection process. In this way, on the one hand, based on the tray code and the tray data table, the position index information of the battery cell in the tray is determined, that is, it is possible to accurately know which positions in the tray have battery cells; on the other hand, based on the position index information, that is, the more specific battery cell position, the tray removal mechanism deployed at the tray removal station is controlled to separate the battery cell from the tray, thereby improving the efficiency and accuracy of separating the battery cell after injection from the tray.

[0089] In some embodiments of the present application, obtaining the pallet code of the pallet in the above step S101 can be implemented by the following steps S201 and S202. Figure 2 FIG. 1 is a flow chart of a method for disassembling a battery cell according to some embodiments of the present application. Figure 2 , the following combination Figure 2 The following instructions are given:

[0090] Step S201: In response to the battery cell arriving at the tray disassembly station, receiving a code scanning signal sent by a controller.

[0091] In the embodiment of the present application, the controller in the injection system where the injection host computer is located sends a code scanning signal to the injection host computer when it detects that the battery cell after injection has arrived at the tray disassembly station. Here, there may be a detector on the tray disassembly station, which sends an arrival signal to the controller when it detects that the battery cell after injection has arrived, so that the controller sends a code scanning signal to the injection host computer.

[0092] Step S202: Based on the code scanning signal, control the code scanning mechanism to scan the pallet, and obtain the pallet code obtained by the code scanning mechanism.

[0093] In the embodiment of the present application, after receiving the code scanning signal, the liquid injection host computer can correspondingly control the code scanning mechanism to scan the pallet to obtain the pallet code. Here, the code scanning mechanism can be deployed on the liquid injection host computer, or the code scanning mechanism can be deployed on the pallet removal station; and the code scanning mechanism can be a code scanning gun.

[0094] It can be understood that, through the above steps, based on the interaction between multiple devices, the pallet code of the pallet can be intelligently acquired to improve the efficiency of acquiring the pallet code.

[0095] In some embodiments of the present application, obtaining the pallet code in the above step S202 may include the following steps S2021 and S2022 (not shown in the figure):

[0096] Step S2021: Based on the code scanning signal, control the code scanning mechanism to scan the tray to obtain an initial code obtained by the code scanning mechanism.

[0097] Step S2022: When the verification result corresponding to the initial code is successful, the initial code is determined as the pallet code.

[0098] In the embodiment of the present application, the scanning mechanism can be further controlled to scan the pallet based on the acquired scanning signal, and the obtained initial code can be verified. Here, the verification includes but is not limited to: verifying the format of the initial code and verifying the length of the initial code to obtain a corresponding verification result. Here, if the verification result is successful, the initial code can be determined as the pallet code.

[0099] Continuing from the above description, determining that the verification result corresponding to the initial code of the pallet is successful may mean that the format of the initial code is consistent with the format of the preset pallet code, and the length of the initial code is the same as the length of the preset pallet code. Here, the preset pallet code may be data pre-stored in the host computer.

[0100] It should be noted that, when the verification result corresponding to the initial code is a verification failure, the verification can be performed again accordingly, or a new initial code can be identified again and verified again accordingly to avoid the probability of verification errors or errors in the link of obtaining the initial code; or, when the verification result corresponding to the initial code is a verification failure, a verification failure signal or an alarm signal can be issued accordingly. Here, the verification failure signal can also be sent to the controller so that the controller can perform relevant operations accordingly, such as: shutting down (stopping the operation of the injection host computer, and / or stopping the operation of itself, and / or stopping the operation of the code scanning mechanism), so that relevant staff can check the cause of the abnormality, etc.

[0101] It can be understood that, through the above steps, when the initial code of the pallet code is read, it is correspondingly verified to improve the accuracy of the pallet code obtained subsequently.

[0102] In some embodiments of the present application, the tray disassembly mechanism includes a gripping mechanism, and the separation of the tray and the battery cell in the above step S103 can be achieved by the following steps S301 and S302. Figure 3 FIG. 1 is a schematic diagram of a method for injecting liquid into a battery cell according to some embodiments of the present application. Figure 3 , the following combination Figure 3 The following instructions are given:

[0103] Step S301: sending the tray code and the location index information to a controller to receive a tray removal signal sent by the controller.

[0104] In an embodiment of the present application, the liquid injection host computer transmits the acquired pallet code and position index information to the controller, so that the controller sends a tray removal signal carrying the pallet code and position index information.

[0105] Step S302: Based on the tray removal signal, control the grasping mechanism to grasp the battery cells in the tray to the next station to separate the tray and the battery cells, so that the battery cells enter the next station in the injection process.

[0106] In an embodiment of the present application, the tray removal signal carries position index information and a tray code, so that the injection host computer can control the grasping mechanism to grasp the battery cells in the tray to the next workstation based on the received tray removal signal (it has known which positions in the tray have battery cells).

[0107] In the embodiment of the present application, the number of cells that can be grabbed by the grabbing mechanism at one time can be 8 or one. Here, after the tray carries multiple cells after liquid injection, the liquid injection host computer can control the grabbing mechanism to grab the cells in the tray one by one based on the tray removal signal, and can also control the grabbing mechanism to grab a preset number of cells in the tray; wherein the preset number is an integer greater than 1.

[0108] It can be understood that, through the above steps, based on the tray code and position index information, the tray removal signal sent by the controller is obtained, so that based on the tray removal signal, the gripping mechanism can be accurately and efficiently controlled to detach the battery cells from the tray.

[0109] Based on the above description, in the method for depalletizing a battery cell provided in an embodiment of the present application, after the battery cell is transported to the next station, the data associated with the battery cell in the previously stored pallet data table may be updated, such as clearing operations, that is, after step S103, the following step A may be performed:

[0110] Step A: after the battery cell is transported to the next workstation, based on the pallet code and the location index information, update the data of the battery cell in the pallet data table.

[0111] In an embodiment of the present application, after the battery cell is transported to the next workstation, that is, after the battery cell is grabbed from the pallet, the data associated with the battery cell in the pallet data table, such as parameters such as the position index information of the battery cell in the pallet, can be cleared accordingly, thereby updating the battery cell data in the pallet data table.

[0112] It should be noted that if a pallet carries multiple battery cells, such as 32, the position index information of each battery cell in the pallet data table may be cleared after each battery cell is separated from the pallet; that is, a battery cell is grabbed to the next workstation, and the data of the battery cell in the pallet data table is cleared accordingly among the data of all battery cells associated with the pallet.

[0113] It is understandable that, through the above steps, after the battery cell is transported to the next station, the data related to the battery cell in the tray data table can be updated, such as cleared. In this way, the battery cell data associated with the tray in the tray data table can be matched in real time with the specific battery cell information in the tray during the actual battery cell injection process, thereby improving the injection stability and efficiency of the battery cell in the injection process.

[0114] Correspondingly, after all the battery cells in the tray have been transported to the next station, the information associated with the tray code in the tray data table can be cleared accordingly, so that the tray can be operated to carry new battery cells again for liquid injection and other operations, that is, the method for disassembling the battery cells provided in the embodiment of the present application can also perform the following steps B1 and B2:

[0115] Step B1: After all the battery cells in the tray have been transported to the next workstation, receiving a clear signal sent by the controller.

[0116] In the embodiment of the present application, after the controller detects that all the cells in the tray have been transported to the next station, it may send a clear signal to the liquid injection host computer accordingly.

[0117] Step B2: based on the clear signal, clear the information associated with the tray code in the tray data table, so that the tray can carry new battery cells again in the liquid injection process.

[0118] In an embodiment of the present application, the injection host computer clears the information associated with the pallet code in the pallet data table, that is, all information associated with the pallet, based on the received clear signal, so that the pallet can carry new battery cells again during the injection process, such as: battery cells after injection and battery cells to be injected.

[0119] It should be noted that the information associated with the pallet code in the pallet data table includes but is not limited to: the cell code of the battery cell carried by the pallet, the position index information of the battery cell in the pallet, the station identification of the pallet at the pallet disassembly station (and any station in the liquid injection process), the pallet code and other information.

[0120] It is understandable that, through the above steps, after all the cells in the tray are transported to the next station, all the data associated with the tray in the tray data table can be cleared. In this way, the tray can be reused next time, that is, it can provide a basis for carrying new cells into the relevant operations in the injection process, thereby improving the injection stability and efficiency of the cells in the injection process.

[0121] Correspondingly, the injection host computer can present a tray disassembly display interface, which can be used to display multiple information involved in the above embodiment, such as: tray code of the tray, position index information of the battery cell in the tray, etc. Correspondingly, steps S101 to S103 provided in the above embodiment can be implemented by following steps S401 to S404. Please refer to Figure 4 As shown, Figure 4 Schematic diagram of the process of disassembling the battery cell provided in some embodiments of the present application Figure 4 The following combination Figure 4 The following instructions are given:

[0122] Step S401, presenting a disk disassembly display interface.

[0123] Wherein, the disk disassembly display interface includes a disk disassembly data frame.

[0124] Step S402: In response to the battery cell arriving at the tray depalletizing station, displaying the tray code in the tray depalletizing data frame.

[0125] Step S403: Based on the pallet code and the pallet data table, display the position index information of the battery cell in the pallet in the pallet removal data frame.

[0126] Step S404, in response to the tray disassembly mechanism separating the tray and the battery cells based on the position index information and the tray code.

[0127] Wherein, the disc disassembly mechanism is deployed on the disc disassembly station.

[0128] In some embodiments of the present application, the presentation form of the disk disassembly data frame included in the disk disassembly display interface may be determined according to actual needs; illustratively, the disk disassembly data frame is displayed in a table form or a curve form. Here, the disk disassembly data frame is displayed in any area of ​​the disk disassembly display interface.

[0129] It should be noted that the disassembly display interface includes but is not limited to the above-mentioned disassembly data frame; it can also display the schematic architecture diagram of the injection host computer in different dimensions (three-dimensional and / or two-dimensional).

[0130] In the embodiment of the present application, for the specific implementation instructions of the above steps S401 to S403, reference may be made to the detailed description of the above-mentioned method for disassembling the battery cell.

[0131] Here, see Figure 5 , which is a schematic diagram of a disk disassembly display interface shown in some embodiments of the present application; wherein the disk disassembly display interface 501 includes: a disk disassembly data frame 5011; here, Figure 5 This is just an example, and the disassembly display interface in the actual production process of the battery cell can be determined according to actual needs.

[0132] It can be understood that through the above steps, on the one hand, based on the pallet code and the pallet data table, the position index information of the battery cells in the pallet is determined, that is, it is possible to accurately know which positions in the pallet have battery cells, and then display the position index information to facilitate viewing by relevant operators; on the other hand, based on the position index information, the pallet disassembly mechanism deployed at the pallet disassembly station is controlled to separate the battery cells from the pallet, and the real-time updated pallet data table is simultaneously displayed on the display interface, which can not only present the separation data changes more clearly and specifically, but also improve the efficiency and accuracy of separating the battery cells and the pallet after liquid injection.

[0133] In the embodiment of the present application, the injection host computer can also display the updated pallet data table in the pallet removal data frame in response to the battery cell being transported to the next station. Here, the updated pallet data table is obtained by updating the data of the battery cell in the pallet data table based on the pallet code and the location index information.

[0134] Correspondingly, the disassembly display interface includes: clearing controls, and the disassembly method also includes:

[0135] Step C: in response to the battery cells in the tray being all transported to the next workstation, receiving a trigger for the clear control, and displaying the cleared tray data table in the tray removal data frame.

[0136] The cleared pallet data table is obtained after clearing the information associated with the pallet code in the pallet data table.

[0137] It can be understood that through the above steps, the updated pallet data table and the cleared pallet data table are displayed in real time in the pallet disassembly data frame, which can not only present the separation data changes more clearly and specifically, but also facilitate the relevant operators of the liquid injection host computer to view and analyze the data.

[0138] In some embodiments of the present application, based on the presentation of the tray disassembly display interface provided in the above embodiments by the liquid injection host computer, a corresponding display interface of the liquid injection host computer as shown below can be presented accordingly to enrich the display function of the liquid injection host computer, thereby providing a more comprehensive human-computer interaction control interface.

Here, the status display area 604 may display, for example: the connection status between the PLC communicating with the injection host computer, the scanning status of the battery cell to be injected at the front end of the injection process, the Hipot test status, etc. In addition, the display interface 600 may also present a user login area, i.e. 605, for operating the injection host computer.

[0140] In addition, the function interface selection area 601 may also involve: data display interfaces related to multiple operations corresponding to the battery cell in the liquid injection process, such as: generating data output, Hipot process diagram, real-time display of production data, alarm query, data query, parameter configuration, electronic scale inspection involved in the weighing process, test tools, user management and authority management.

Here, 701 is the data for output analysis in a table form and in time periods, wherein the time periods can be divided into 7: 08:00-09:00, 09:00-10:00, 10:00-11:00, 11:00-12:00, 12:00-13:00, 14:00-15:00, 15:00-16:00, 16:00-17:00, 17:00-18:00; and the production data output can be divided into output (the total output of the battery cell in the injection link) and NG output (defective product output). At the same time, 702 is data for production analysis in the form of charts and time periods, and is also divided into good products and defective products, that is, OK products and NG products.

[0142] It should be noted that defective products and good products can be distinguished based on the relevant data generated by the battery cells during the liquid injection process. For example, defective products are batteries whose corresponding measured voltage and / or resistance are abnormal, the front and rear weighing data are not within the preset important range, the liquid injection parameters are abnormal, etc.

[0146] Correspondingly, some embodiments of the present application also provide a battery cell disassembly system, please refer to Fig.11 As shown, Fig.11 A schematic diagram of the structure of a battery cell disassembly system provided in some embodiments of the present application. The disassembly system 1100 includes: a liquid injection host computer 1101, a controller 1102, and a disassembly mechanism 1103 deployed at a disassembly station, wherein:

[0147] In response to the battery cell after injection arriving at the tray removal station, the liquid injection host computer 1101 obtains the tray code of the tray under the action of the controller 1102; wherein the tray is used to carry the battery cell;

[0148] The injection host computer 1101 determines the position index information of the battery cell in the tray in the tray data table obtained by the code reading station based on the tray code; wherein the code reading station is the station before the tray removal station;

[0149] Based on the position index information and the tray code, the liquid injection host computer 1101 controls the tray removal mechanism 1103 to separate the tray and the battery cell under the action of the controller 1102, so that the battery cell enters the next station in the liquid injection process.

[0150] In some embodiments of the present application, the tray disassembly system 1100 also includes: a code scanning mechanism 1104, and the liquid injection host computer 1101 receives a code scanning signal sent by the controller 1102 in response to the battery cell arriving at the tray disassembly station; the liquid injection host computer 1101 controls the code scanning mechanism to scan the tray based on the code scanning signal, and obtains the tray code obtained by the code scanning mechanism 1104.

[0151] In some embodiments of the present application, the battery cell disassembly system 1100 can be applied to the battery cell disassembly method provided in any of the above embodiments. For detailed descriptions of the liquid injection host computer 1101, the controller 1102, and the disassembly mechanism 1103 deployed at the disassembly station, reference can be made to the detailed descriptions of the battery cell disassembly method mentioned above.

[0152] The battery cell disassembly system provided in the present application is explained below in a specific embodiment.

[0153] When the battery cells are transported to the tray depalletizing station in the liquid injection process, the battery cell depalletizing system will correspondingly execute the following three processes: 1. Depalletizing code scanning; 2. Depalletizing; 3. Clearing the tray memory.

[0154] Among them, see Fig.12 As shown in the figure, in the battery cell disassembly system, the disassembly and code scanning are realized based on the controller 121, the injection host computer 122 and the code scanning gun 123, which specifically includes:

[0155] 1201, start;

[0156] 1202. The controller 121 sends a tray removal code scanning trigger to the liquid injection host computer 122. Here, the controller 121 may detect that the battery cell after liquid injection arrives at the tray removal station, and then send a tray removal code scanning signal to the liquid injection host computer 122;

[0157] 1203, the injection host computer 122 reads the unpacking disk scanning code trigger;

[0158] 1204. The liquid injection host computer 122 sends a code scanning instruction to the code scanning gun 123. Here, the liquid injection host computer 122 may send the code scanning instruction to the code scanning gun 123 based on the received disk disassembly code scanning trigger signal;

[0159] 1205. The barcode scanner 123 scans the barcode. Here, the barcode scanner 123 may scan the tray carrying the battery cells based on the received barcode scanning instruction to obtain the tray code of the tray (here, the tray code may be a barcode);

[0160] 1206. The liquid injection host computer 122 verifies the pallet code scanned by the barcode scanner 123 (whether the length and format are qualified) and obtains the corresponding verification result;

[0161] 1207. When the pallet code verification result is qualified, the liquid injection host computer 122 searches for the cell index position matching the pallet code from the previously obtained pallet data table;

[0162] 1208. After the liquid injection host computer 122 finds the battery cell index position, it ends the liquid injection code scanning.

[0163] It should be noted that during the pallet unpacking and code scanning process, each process performed by the liquid injection host computer 122 will send a signal to the controller 121 accordingly, so that the controller 121 can obtain the real-time workflow of the liquid injection host computer 122 in real time. Here, if the liquid injection host computer 122 fails to verify the pallet code, and if the battery cell index position is not found, the corresponding verification failure signal and the signal that no relevant information is found will be sent to the controller 121.

[0164] Correspondingly, see Fig.13 As shown, the disassembly system of the battery cell is based on the controller 121 and the liquid injection host computer 122 to realize the disassembly, which specifically includes:

[0165] 1301, start;

[0166] 1302. The controller 121 sends a tray removal trigger to the injection host computer 122;

[0167] 1303, the liquid injection host computer 122 reads the signal corresponding to the tray removal trigger sent by the controller 121;

[0168] 1304. The liquid injection host computer 122 reads the previously known position index information of the battery cell in the tray and the tray code, etc. based on the corresponding signal triggered by the tray removal;

[0169] 1305. The liquid injection host computer 122 updates the data of the battery cells in the tray data table according to the tray code and the position index information. Here, the liquid injection host computer 122 controls the grabbing mechanism to grab the battery cells in the tray based on the tray removal trigger signal, thereby adaptively updating the data of the battery cells in the tray data table.

[0170] 1306. End.

[0171] Here, in the process of disassembling the plate, each process executed by the liquid injection host computer 122 will correspondingly send a signal to the controller 121, so that the controller 121 can obtain the real-time working data of the liquid injection host computer 122 in real time.

[0172] Correspondingly, see Fig.14 As shown, in the battery cell disassembly system, the tray memory is cleared based on the controller 121 and the liquid injection host computer 122, which specifically includes:

[0173] 1401, start;

[0174] 1402, the controller 121 sends a tray removal trigger to the injection host computer 122;

[0175] 1403, the injection host computer 122 reads the signal corresponding to the tray removal trigger sent by the controller 121;

[0176] 1404. The liquid injection host computer 122 reads the pallet code of the pallet based on the received pallet removal trigger;

[0177] 1405. The liquid injection host computer 22 deletes the pallet data in the pallet data table based on the pallet code read;

[0178] 406. End.

[0179] Here, in the tray memory clearing process, the liquid injection host computer 122 also sends a signal to the controller 121 correspondingly when executing each step, so that the controller 121 obtains the real-time working data of the liquid injection host computer 122 in real time.
