[0049] To make the purpose, technical solutions and advantages of the embodiments of the present disclosure more clear, the specific technical solutions of the present disclosure will be further described in detail below in conjunction with the drawings in the embodiments of the present disclosure. The following embodiments are used to illustrate the present disclosure, but are not intended to limit the scope of the present disclosure.

[0050] Unless otherwise defined, all technical and scientific terms used in this disclosure have the same meaning as commonly understood by those skilled in the art in the art of this disclosure. The terms used in this disclosure are only for the purpose of describing the present embodiment and are not intended to limit this disclosure.

[0051] In the following description, references to “some embodiments,” “this embodiment,” “this embodiment,” and examples, etc., describe a subset of all possible embodiments, but it can be understood that “some embodiments” may be the same subset or different subsets of all possible embodiments, and may be combined with each other without conflict.

[0052] If similar descriptions of "first / second" appear in the public document, the following explanation is added. In the following description, the terms "first\second\third" are merely used to distinguish similar objects and do not represent a specific order of the objects. It can be understood that "first\second\third" can be interchanged with a specific order or sequence where permitted, so that the embodiment described herein can be implemented in an order other than that illustrated or described herein.

[0053] In the embodiments of the present disclosure, 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.

[0054] At present, the application of new energy batteries in life and industry is becoming more and more extensive. New energy batteries are not only used in energy storage power supply systems such as hydropower, thermal power, wind power and solar power stations, but are also widely used in electric vehicles such as electric bicycles, electric motorcycles, electric cars, as well as in aerospace and other fields. With the continuous expansion of the application field of power batteries, the market demand is also constantly expanding. In the embodiments of the present disclosure, 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 battery pack, thereby being used to supply power to electrical devices. A battery cell may be a secondary battery, which refers to a battery cell that can continue to be used by activating 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 embodiments of the present disclosure are not limited to this.

[0055] In the embodiment of the present disclosure, 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 through a busbar.

[0056] 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 battery cell liquid injection process, the battery cells after liquid injection are separated from the tray that carries the battery cells. The mechanical gripper needs to know which positions of the battery cells are located in the tray to be disassembled so as to grab the battery cells and separate the tray from the battery cells. Here, if the mechanical gripper cannot accurately know the specific position of the battery cells in the tray, it will lead to low efficiency and low accuracy in the process of separating the battery cells from the tray.

[0057] Based on the above technical problems, some embodiments of the present disclosure provide a system and method for disassembling battery cells. The method for disassembling battery cells includes: first, in response to the arrival of the battery cells after liquid injection at the disassembling station, obtaining the tray code of the tray; wherein the tray is used to carry the battery cells, and based on the tray code, determining the position index information of the battery cells in the tray 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, controlling the disassembling mechanism deployed at the disassembling station to separate the tray and the battery cells so that the battery cells enter 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 cells 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 disassembling mechanism deployed at the disassembling station is controlled to separate the battery cells from the tray, thereby improving the efficiency and accuracy of separating the battery cells and the tray after liquid injection.

[0058] 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 disclosure as an example. The method for disassembling a battery cell is applied to a liquid injection host computer. FIG1 is a flow chart of a method for disassembling a battery cell provided in some embodiments of the present disclosure. The following description is made in conjunction with FIG1 :

[0059] Step S101: In response to the battery cells after injection arriving at the tray depalletizing station, a tray code of the tray is obtained.

[0060] Wherein, the tray is used to carry the battery core.

[0061] In the disclosed embodiment, 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 the processor may execute the method for disassembling the battery cell when running the program.

[0062] In the embodiment of the present disclosure, the injection host computer can exchange data with the controller; wherein the controller can be: a programmable logic controller (PLC) and the like.

[0063] In the embodiment of the present disclosure, 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 disclosure does not impose any limitation on this.

[0064] 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.

[0065] In the embodiments of the present disclosure, 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 make up 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: lithium-ion battery cell (Li-ion Cell), lithium polymer battery cell (Li-polymer Cell), nickel metal hydride battery cell (NiMH Cell), etc. The embodiments of the present disclosure do not impose any restrictions on the type of battery cell, and the specific type can be selected according to the actual application scenario.

[0066] In the embodiment of the present disclosure, the battery cell is the core component of the battery pack, and 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 intended to store electrical energy and provide power supply. The components of the battery pack include at least: battery cells, battery management system (BMS), casing, connecting wiring harness, connectors and interfaces, 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 embodiment of the present disclosure does not impose any restrictions on this, and the specific selection can be made according to the actual application scenario.

[0067] In the disclosed embodiments, the tray removal station may be a station for separating battery cells from the tray on which they are carried; wherein the tray removal station may be equipped with a gripping mechanism (mechanical gripper) for gripping the battery cells. Here, the gripping mechanism is a typical robot end effector, primarily used to perform operations such as gripping, transporting, placing, and releasing.

[0068] In the disclosed embodiments, the tray is used to carry (filled) battery cells, i.e., battery cells that have entered the filling process and have been filled. The tray may be provided with multiple slots for holding multiple battery cells (batteries). The battery cells held in the slots can be used for related operations such as filling, welding, or welding inspection. Furthermore, the multiple slots on the tray are configured with corresponding shapes and sizes to match the battery cells or batteries.

[0069] In the embodiment of the present disclosure, the number of slots on the tray can be 8, 10, 32, etc. Here, the number of the slots can be determined according to the actual battery cell filling requirements; there is no limitation on this in the embodiment of the present disclosure.

[0070] In the disclosed embodiment, after the injection of the battery cells, the battery cells may arrive at the depalletizing station by means of a relevant battery cell transport mechanism, which transports the pallet carrying the battery cells to the depalletizing station. Alternatively, the control system (controller) corresponding to the battery cells during the injection process may control the pallet transport so that the injected battery cells arrive at the depalletizing station; or the controller may control the relevant gripping mechanism to grip the injected battery cells from the previous station to the depalletizing station.

[0071] In the embodiment of the present disclosure, the number of battery cells after liquid injection can be one or more, and the embodiment of the present disclosure does not impose any limitation on this.

[0072] In the embodiment of the present disclosure, the pallet code may be in the form of a barcode, a QR code, etc., and the present disclosure does not impose any limitation on this.

[0073] It should be noted that pallet codes are usually used in logistics, such as battery cell transportation management, to identify and track the loaded battery cells.

[0074] In the embodiment of the present disclosure, the pallet code may be a mark on the pallet, or may be a pallet code associated with the pallet and stored inside the liquid injection host computer.

[0075] In the embodiment of the present disclosure, the liquid injection host computer can control the relevant scanning mechanism to scan the tray under the action of the reading signal sent by the controller to obtain the tray code (barcode) of the tray.

[0076] In the embodiment of the present disclosure, when the battery cells after injection arrive at the tray removal station, the tray can be imaged and the tray code of the tray carrying the battery cells can be obtained by identifying the image obtained from the image capture.

[0077] 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 position of the battery cells in the tray based on the tray code, thereby improving the efficiency and accuracy of the subsequent separation of the battery cells after liquid injection from the tray.

[0078] Step S102: Based on the pallet code, determine the position index information of the battery cell in the pallet in the pallet data table obtained by the code reading station.

[0079] Among them, the code reading station is the station before the disk disassembly station.

[0080] In the disclosed embodiment, the liquid injection host computer obtains the corresponding position index information from a previously known pallet data table based on the pallet code. The position index information may be generated when the battery cells are placed on the pallet, and the battery cells may have been placed on the pallet before arriving at the depalletizing station. Thus, the liquid injection host computer can obtain the position index information from the previously generated relevant data.

[0081] In the embodiment of the present disclosure, 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 label corresponding to the battery cell in the tray, etc.

[0082] In the embodiment of the present disclosure, the pallet data table can 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.

[0083] In the disclosed embodiment, the tray removal station and the barcode reading station can be adjacent or separated. For example, there can be other stations in between, such as an inspection station and a liquid injection station. Here, the barcode reading station can be the first station in the liquid injection process.

[0084] It should be noted that the pallet data table can include information related to multiple pallets. Here, the relevant information for each pallet may include at least: the pallet code, the location index information of the battery cells within the pallet, and the location mark of the pallet at the workstation. The pallet code, location index information, and location mark of each pallet are in a one-to-one correspondence.

[0085] It is 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 pre-stored pallet data table. This improves the efficiency of obtaining the position index information and provides parameter support for the subsequent separation of the battery cells from the pallet.

[0086] 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.

[0087] In the embodiment disclosed herein, after obtaining the position index information and the pallet code, the liquid injection host computer can, under the action of the controller, control the pallet removal mechanism deployed at the pallet 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.

[0088] It should be noted that the tray removal mechanism deployed at the tray removal station can be arranged corresponding to the battery cells on the tray removal station, and the embodiments of the present disclosure do not impose any restrictions on this. For example, the tray removal mechanism can be deployed directly above the tray removal station, or it can be deployed to the side of the tray removal station and can rotate at a preset angle to achieve the purpose of grabbing the battery cells on the tray removal station.

[0089] It should be noted that the number of battery cells that the tray removal mechanism can grab at one time can be determined according to actual needs, and the embodiments of the present disclosure do not impose any limitation on this.

[0090] In the embodiment of the present disclosure, the next station in the liquid 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 disclosure does not impose any limitation on this.

[0091] It can be understood that through the above scheme, first, in response to the battery cells arriving at the tray removal station after injection, the tray code of the tray carrying the battery cells is obtained, and based on the tray code, the position index information of the battery cells 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 cells, so that the battery cells enter 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 cells 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 cells from the tray, thereby improving the efficiency and accuracy of separating the battery cells and the tray after injection.

[0092] In some embodiments of the present disclosure, obtaining the tray code of the tray in step S101 can be achieved by following steps S201 and S202. Referring to FIG2 , which is a second flow chart of the method for disassembling a battery cell tray provided in some embodiments of the present disclosure, the following description is provided in conjunction with FIG2 :

[0093] Step S201: In response to the battery cell arriving at the tray disassembly station, a code scanning signal sent by a controller is received.

[0094] In the disclosed embodiment, a controller within the injection system in which the injection host computer is located sends a code scanning signal to the injection host computer upon detecting that a cell after injection has arrived at the tray removal station. Here, a detector may be present at the tray removal station, which, upon detecting the arrival of a cell after injection, sends an arrival signal to the controller, causing the controller to send a code scanning signal to the injection host computer.

[0095] 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.

[0096] In the disclosed embodiment, after receiving the code scanning signal, the liquid filling 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 filling host computer, or deployed on the pallet removal station; and the code scanning mechanism can be a code scanning gun.

[0097] 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.

[0098] In some embodiments of the present disclosure, obtaining the pallet code in step S202 may include the following steps S2021 and S2022 (not shown in the figure):

[0099] Step S2021: Based on the code scanning signal, control the code scanning mechanism to scan the tray and obtain an initial code obtained by the code scanning mechanism.

[0100] Step S2022: If the verification result corresponding to the initial code is successful, the initial code is determined as the pallet code.

[0101] In the disclosed embodiment, the scanning mechanism can be controlled to scan the pallet based on the acquired scanning signal, and the obtained initial code can be verified. Verification includes, but is not limited to, verifying the format and length of the initial code to obtain a corresponding verification result. If the verification result is successful, the initial code can be determined to be the pallet code.

[0102] Continuing with the above description, determining that the verification result corresponding to the initial pallet code is successful can 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 can be data pre-stored within the host computer.

[0103] It should be noted that, if the verification result corresponding to the initial code is a verification failure, the verification can be performed again, or a new initial code can be identified and obtained again and the verification can be performed again accordingly to avoid the possibility of verification errors or errors in the process of obtaining the initial code; or, if 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 liquid injection host computer, and / or stopping the operation of the controller itself, and / or stopping the operation of the code scanning mechanism) so that relevant staff can check the cause of the abnormality, etc.

[0104] It is understandable 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.

[0105] In some embodiments of the present disclosure, the tray removal mechanism includes a gripping mechanism. The separation of the tray and the battery cell in step S103 can be achieved by following steps S301 and S302. Referring to FIG3 , which is a flow diagram of a third method for injecting liquid into a battery cell according to some embodiments of the present disclosure, the following description is provided in conjunction with FIG3 :

[0106] Step S301: Send the tray code and the location index information to the controller to receive a tray removal signal sent by the controller.

[0107] In the embodiment of the present disclosure, the liquid injection host computer sends 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.

[0108] Step S302: Based on the tray removal signal, control the grabbing mechanism to grab 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.

[0109] In the disclosed embodiment, the tray removal signal carries position index information and a pallet code, so that the liquid injection host computer can control the gripping mechanism to grab the battery cells in the tray and move them to the next workstation based on the received tray removal signal (it has been known which positions in the tray have battery cells).

[0110] In the disclosed embodiment, the gripping mechanism can grip eight or one battery cell at a time. When a tray carries multiple injected battery cells, the injection host computer can control the gripping mechanism to grip the battery cells in the tray one by one based on the tray removal signal. Alternatively, the gripping mechanism can control the gripping mechanism to grip a preset number of battery cells in the tray; the preset number is an integer greater than 1.

[0111] 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 cell from the tray.

[0112] Based on the above description, in the method for depalletizing a battery cell provided in an embodiment of the present disclosure, after the battery cell is transported to the next workstation, the data associated with the battery cell in the previously stored pallet data table may be updated, such as by clearing the data. That is, after step S103, the following step A may be performed:

[0113] Step A: After the battery cell is transported to the next workstation, the data of the battery cell in the pallet data table is updated based on the pallet code and the location index information.

[0114] In an embodiment of the present disclosure, 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 the position index information of the battery cell in the pallet and other parameters, can be cleared accordingly, thereby updating the battery cell data in the pallet data table.

[0115] 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.

[0116] It is understood that through the above steps, after a battery cell is transported to the next workstation, the data related to the battery cell in the tray data table can be updated, such as cleared. This allows the battery cell data associated with the tray in the tray data table to match the specific battery cell information in the tray during the actual battery cell filling process in real time, thereby improving the battery cell filling stability and efficiency during the filling process.

[0117] Correspondingly, after all the battery cells in the pallet have been transported to the next workstation, the information associated with the pallet code in the pallet data table can be cleared to enable the pallet to operate and carry new battery cells for liquid injection and other operations. That is, the battery cell depalletizing method provided by the embodiment of the present disclosure can also perform the following steps B1 and B2:

[0118] Step B1: After all the battery cells in the tray have been transported to the next workstation, a clear signal sent by the controller is received.

[0119] In the embodiment of the present disclosure, after the controller detects that all the battery cells in the tray have been transported to the next workstation, it may send a clear signal to the liquid injection host computer accordingly.

[0120] 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 filling process.

[0121] In the embodiment of the present disclosure, the liquid 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 liquid injection process, such as: battery cells after liquid injection and battery cells to be injected.

[0122] 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 depalletizing station (and any station in the liquid injection process), the pallet code and other information.

[0123] It is understood that through the above steps, after all battery cells in the tray are transported to the next workstation, all data associated with the tray in the tray data table can be cleared. This provides a basis for the tray to be reused next time, that is, to carry new battery cells into the relevant operations of the liquid filling process, thereby improving the liquid filling stability and efficiency of the battery cells during the liquid filling process.

[0124] Correspondingly, the liquid injection host computer can present a tray disassembly display interface, which can be used to display multiple information involved in the above embodiments, such as: the tray code of the tray, the position index information of the battery cell in the tray, etc. Correspondingly, steps S101 to S103 provided in the above embodiments can be implemented by following steps S401 to S404.

[0136] In the disclosed embodiment, the liquid injection host computer may further display the updated pallet data table in the depalletizing data frame in response to the battery cell being transported to the next workstation. Here, the updated pallet data table is obtained by updating the battery cell data in the pallet data table based on the pallet code and the location index information.

[0138] 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.

[0139] The cleared pallet data table is obtained after clearing the information associated with the pallet code in the pallet data table.

[0140] 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.

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:

[0150] In response to the arrival of the injected battery cell at the tray removal station, the liquid injection host computer 1101 obtains the tray code of the tray under the control of the controller 1102; wherein the tray is used to carry the battery cell;

[0151] The liquid injection host computer 1101 determines the position index information of the battery cell in the tray based on the tray code in the tray data table obtained by the code reading station; wherein the code reading station is the station before the tray removal station;

[0157] 12 shows a battery cell disassembly system, in which disassembly and barcode scanning are implemented based on a controller 121, a liquid injection host computer 122, and a barcode scanner 123. The system specifically includes:

[0158] 1201, start;

[0159] 1202. The controller 121 sends a scan code trigger for unpacking to the liquid injection host computer 122. Here, the controller 121 may detect that the battery cell after liquid injection arrives at the unpacking station and then send a scan code signal for unpacking to the liquid injection host computer 122.

[0160] 1203, the liquid injection host computer 122 reads the disk removal code scan trigger;

[0161] 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 removal code scanning trigger signal;

[0163] 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;

[0164] 1207. When the pallet code verification result is qualified, the liquid injection host computer 122 searches the previously obtained pallet data table for the cell index position that matches the pallet code;

[0165] 1208. After the liquid filling host computer 122 finds the battery cell index position, it ends the liquid filling code scanning.

[0166] It should be noted that during the pallet removal and code scanning process, each process executed by the liquid injection host computer 122 will send a corresponding signal to the controller 121, 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 the pallet code verification result or fails to query the battery cell index position, it will send a corresponding verification failure signal and a signal that no relevant information was found to the controller 121.

[0167] Correspondingly, referring to FIG13 , the battery cell disassembly system is based on the controller 121 and the liquid injection host computer 122 to realize the disassembly, which specifically includes:

Here, the liquid injection host computer 122 controls the gripping mechanism to grip the battery cells in the pallet based on the pallet removal trigger signal, thereby adaptively updating the battery cell data in the pallet data table.

[0173] 1306. End.

[0174] Here, in the process of disassembling the tray, 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.

[0175] Correspondingly, referring to FIG14 , in the battery cell disassembly system, the tray memory clearing is implemented based on the controller 121 and the liquid injection host computer 122, which specifically includes:

[0180] 1405. The liquid injection host computer 22 deletes the pallet data in the pallet data table based on the pallet code read;
