Description

Technical Field

[0001] This application relates to the field of battery manufacturing technology, and in particular to a cell delivery system and a cell delivery method. Background Technology

[0002] New energy batteries are being used more and more widely in daily life and industry. For example, new energy vehicles equipped with batteries are already widely used. In addition, batteries are being used more and more in the field of energy storage.

[0003] Batteries are obtained by processing battery cells through multiple processes. Currently, as battery cells leave the target process one by one, it is necessary to determine whether each battery cell has completed the process flow for this process. Since the determination time is long, it will increase the time cycle of this process and reduce the efficiency of battery cell leaving the station. Summary of the Invention

[0004] To address the aforementioned technical problems, the purpose of this application is to provide a battery cell dispatching system and a battery cell dispatching method.

[0005] This application is achieved through the following technical solution.

[0006] The first aspect of this application provides a battery cell outbound system, the system including a host computer and a control device; the host computer is configured to respond to a received outbound trigger signal, read the battery cell code corresponding to the outbound trigger signal from the control device; and, if it is determined that the data reading is successful based on the battery cell code, request an outbound result from a preset management platform corresponding to the battery cell code, and send the preset management platform outbound result and the battery cell code to the control device, so that the control device adds an outbound marker corresponding to the preset management platform outbound result to the battery cell code; the control device is configured to respond to a received trigger verification signal, read the target outbound marker on the target battery cell code corresponding to the trigger verification signal, and determine whether to perform a normal outbound process for the target outbound battery cell corresponding to the target battery cell code based on the target outbound marker.

[0007] Therefore, when a battery cell leaves the station, it needs to determine whether the cell can leave normally based on the exit result requested from the preset management platform. However, there is a certain waiting time for the exit result to be returned when requesting the preset management platform, which will increase the exit cycle time of the battery cell. The battery cell exit method proposed in this application is an asynchronous exit method. When the battery cell leaves the station, it only needs to read the cell code and then release the cell. The exit operation is then performed on the next battery cell. At the same time, the exit result is requested from the preset management platform based on the cell code. The exit result only needs to be received from the preset management platform before the battery cell moves to the next process, that is, before the trigger verification signal is received. Thus, this application can save the time of waiting to request the preset management platform when the battery cell leaves the station, thereby improving the exit efficiency of the battery cell.

[0008] In some embodiments of this application, the system further includes a detection device; wherein: the detection device is used to detect whether the outgoing battery cell has reached the target outgoing position; if it has, it sends a battery cell arrival signal to the control device; the control device is used to respond to the received battery cell arrival signal, determine whether the outgoing battery cell has successfully entered the target process; if the entry is successful, it adds the process data of the target process to the battery process data associated with the battery cell code of the outgoing battery cell, and sends the outgoing trigger signal for the battery cell code to the host computer; if the entry is unsuccessful, it does not send the outgoing trigger signal for the battery cell code to the host computer.

[0009] Based on this, triggering the exit only for cells that have successfully entered the target process can save exit time and avoid wasting time on cells that failed to enter the station, thereby improving the efficiency of cell exit.

[0010] In some embodiments of this application, the control device is further configured to respond to the received cell code and the outbound result of the preset management platform. If the outbound result of the preset management platform indicates that the outbound cell can leave the station normally, a first outbound marker is added to the cell code; if the outbound result of the preset management platform indicates that the outbound cell cannot leave the station normally, a second outbound marker is added to the cell code.

[0011] Based on this, corresponding outbound markers are added to the cell codes according to the outbound results of different preset management platforms. This allows the cells to be processed directly according to the outbound markers during subsequent verification, saving outbound time and improving the efficiency of cell outbound operations.

[0012] In some embodiments of this application, the system further includes a target gripper device; wherein: the control device is further configured to send a first instruction to the target gripper device if the target exit mark is the first exit mark, and send a second instruction to the target gripper device if the target exit mark is the second exit mark; the target gripper device is configured to, in response to the received first instruction, transfer the target exit cell to a normal unloading conveyor belt, so that the normal unloading conveyor belt can transport the target exit cell to the next process; the target gripper device is configured to, in response to the received second instruction, transfer the target exit cell to an abnormal unloading conveyor belt, so that the abnormal unloading conveyor belt can transport the target exit cell to a defective cell placement area.

[0013] Based on this, only the cells that have successfully completed this target process can be transported to the next process, thus ensuring the quality of the cells.

[0014] In some embodiments of this application, the host computer is further configured to determine whether the outgoing battery cell corresponding to the battery cell code is the first outgoing battery cell. If the outgoing battery cell is the first outgoing battery cell, it requests a first-piece verification interface from the preset management platform, so that the preset management platform performs outgoing verification on the battery cell code based on the first-piece verification interface, and obtains the outgoing result of the preset management platform. The host computer is further configured to request a normal verification interface from the preset management platform if the outgoing battery cell is not the first outgoing battery cell, so that the preset management platform performs outgoing verification on the battery cell code based on the normal verification interface, and obtains the outgoing result of the preset management platform. The battery cell code setting rules for the first outgoing battery cell and non-first outgoing battery cells are different.

[0015] Based on this, setting different verification interfaces for different cell codes can save verification time and thus improve the efficiency of cell delivery.

[0016] In some embodiments of this application, the host computer is further configured to, if it is determined that the current data reading is unsuccessful based on the cell code, read the cell code again from the control device and determine again whether the current data reading is successful; the host computer is further configured to, if it is determined that the current data reading is unsuccessful for a consecutive preset number of times, send a reading failure indication message to the control device; the control device is further configured to, in response to the received indication message, add the second outbound marker to the cell code.

[0017] In some embodiments of this application, the host computer is further configured to send a warning signal to the control device if multiple consecutive outbound results received from the preset management platform indicate that the outbound battery cell cannot be outbound normally; the control device is further configured to respond to the received warning signal and generate corresponding alarm information; the alarm information includes at least the reason for triggering the alarm and the corresponding processing suggestions.

[0018] Based on this, by generating early warning information, users can be promptly alerted when a fault occurs in the cell dispatching system, so that users can deal with the fault in a timely manner and avoid slowing down the efficiency of cell dispatching due to the fault.

[0019] The second aspect of this application provides a battery production line, including production equipment, transfer equipment, and the cell exit system of any one of the first aspects, wherein the production equipment is used to produce exit cells, and the transfer equipment is used to remove the exit cells from the production equipment and place them in the cell exit system, or to remove the exit cells from the cell exit system and transfer them to a target workstation.

[0020] A third aspect of this application provides a method for battery cell outbound processing, applied to a battery cell outbound system, the system including a host computer and a control device; the method includes: the host computer displaying an outbound display interface, wherein the outbound display interface includes a battery cell outbound display frame and a preset management platform outbound result display frame; the host computer responds to a received outbound trigger signal, reads the battery cell code corresponding to the outbound trigger signal from the control device; and, if it determines that the data reading is successful based on the battery cell code, requests the preset management platform outbound result corresponding to the battery cell code from the preset management platform, and displays the preset management platform... The outbound result is displayed in the outbound result display box of the preset management platform; the host computer sends the outbound result of the preset management platform and the cell code to the control device, so that the control device adds the outbound mark corresponding to the outbound result of the preset management platform to the cell code; the control device responds to the received trigger verification signal, reads the target outbound mark on the target cell code corresponding to the trigger verification signal, displays the target outbound mark in the cell outbound display box, and determines whether to perform the normal outbound process for the target cell code corresponding to the target cell based on the target outbound mark.

[0021] In some embodiments of this application, the method further includes: the host computer determining whether the outgoing battery cell corresponding to the battery cell code is the first outgoing battery cell; if the outgoing battery cell is the first outgoing battery cell, the host computer requests a first-piece verification interface from the preset management platform, so that the preset management platform performs outgoing verification on the battery cell code based on the first-piece verification interface, obtains the outgoing result of the preset management platform, and displays the outgoing result of the preset management platform in the outgoing result display box of the preset management platform; if the outgoing battery cell is not the first outgoing battery cell, the host computer requests a normal verification interface from the preset management platform, so that the preset management platform performs outgoing verification on the battery cell code based on the normal verification interface, obtains the outgoing result of the preset management platform, and displays the outgoing result of the preset management platform in the outgoing result display box of the preset management platform; wherein, the battery cell code setting rules for the first outgoing battery cell and non-first outgoing battery cells are different.

[0022] In some embodiments of this application, the outbound display interface further includes an early warning interface, and the method further includes: if the host computer continuously receives multiple outbound results from the preset management platform indicating that the outbound battery cell cannot leave the station normally, it sends an early warning signal to the control device, so that the control device responds to the received early warning signal and generates corresponding alarm information to send to the host computer; the alarm information includes at least the reason for triggering the alarm and the corresponding handling suggestions; the host computer responds to the received alarm information and displays the alarm information on the early warning interface.

[0023] In this application, once the host computer determines that the cell code of the outgoing cell has been successfully read, it releases the outgoing cell and reads the cell code of the next outgoing cell. Simultaneously, the host computer requests the outgoing result from the preset management platform according to the scanned cell code, and sends the outgoing result and cell code from the preset management platform to the control device. The control device adds an outgoing mark to the cell code based on the outgoing result from the preset management platform. Based on this, the control device only needs to determine the target cell code for the trigger verification signal when it receives the trigger verification signal, and then read the target outgoing mark pre-added to the target cell code from the target cell code, and make a judgment based on the target outgoing mark. The cell outgoing method proposed in this application is an asynchronous outgoing method, which saves the time of waiting to request the preset management platform and improves the outgoing efficiency of the cells.

[0046] The following is a detailed description of this application.

[0047] Battery cells are an important component of batteries. New energy batteries are being used more and more widely in daily life and industry. For example, new energy vehicles equipped with batteries are already widely used. In addition, batteries are increasingly being used in the field of energy storage.

[0048] Currently, new energy batteries are increasingly widely used in daily life and industry. They are not only used in energy storage systems such as hydropower, thermal power, wind power, and solar power plants, but also extensively used in electric vehicles such as electric bicycles, electric motorcycles, and electric cars, as well as in aerospace and other fields. With the continuous expansion of the application areas of power batteries, the market demand is also constantly increasing. In this embodiment, the battery can be a single battery cell. A single battery cell refers to a basic unit capable of converting chemical energy into electrical energy, which can be used to manufacture battery modules or battery packs to supply power to electrical devices. A single battery cell can be a rechargeable battery, which refers to a battery cell that can be recharged after discharge to activate the active materials and continue to be used. A single battery cell can be a lithium-ion battery, sodium-ion battery, sodium-lithium-ion battery, lithium metal battery, sodium metal battery, lithium-sulfur battery, magnesium-ion battery, nickel-metal hydride battery, nickel-cadmium battery, lead-acid battery, etc., and this embodiment does not limit the types.

[0049] Batteries are obtained by processing battery cells through multiple processes. Currently, as battery cells leave the target process one by one, it is necessary to determine whether each battery cell has completed the process flow for this process. Since the determination time is long, the time cycle of this process will increase, resulting in a decrease in the efficiency of battery cells leaving the station.

[0050] Based on the above problems, this application proposes a cell outgoing system 0, referring to... Figure 1 The battery cell outbound system 0 includes a host computer 1 and a control device 2. The host computer 1 is used to respond to the received outbound trigger signal, read the battery cell code corresponding to the outbound trigger signal from the control device 2, and, if it determines that the data reading is successful based on the battery cell code, request the outbound result of the preset management platform corresponding to the battery cell code from the preset management platform, and send the preset management platform outbound result and the battery cell code to the control device 2, so that the control device 2 can add an outbound mark corresponding to the preset management platform outbound result to the battery cell code. The control device 2 is used to respond to the received trigger verification signal, read the target outbound mark on the target battery cell code corresponding to the trigger verification signal, and determine whether to perform the normal outbound process for the target battery cell corresponding to the target battery cell code based on the target outbound mark.

[0051] It should be noted that, in the embodiments of this application, the control device 2 is a device that can issue control commands, such as a programmable logic controller (PLC); the specific control device 2 can be selected according to the actual situation, and the embodiments of this application do not make specific limitations here.

[0052] It should be noted that, in this embodiment of the application, the cell code is the unique identifier of the outgoing cell, which can be a label, barcode or QR code. Each outgoing cell has a unique cell code, and the information of each outgoing cell can be stored in correspondence with its own cell code. The specific cell code can be determined according to the actual situation, and this embodiment of the application does not make specific limitations here.

[0053] It should be noted that, in this embodiment of the application, the cell code is obtained by scanning the cell at the station using a scanning device. The scanning device is a device that can scan labels, barcodes, or QR codes, such as a barcode scanner or barcode reader. The specific scanning device can be determined according to the actual situation, and this embodiment of the application does not make specific limitations here.

[0054] It should be noted that, in this embodiment of the application, the preset management platform is a Manufacturing Execution System (MES), which is used to store the production information of each battery cell at all historical processes; the specific preset management platform can be selected according to the actual situation, and this embodiment of the application does not make specific limitations here.

[0055] Specifically, when the host computer 1 receives the outbound trigger signal, it reads the cell code and cell process data corresponding to the outbound trigger signal from the PLC. Based on the read cell code and cell process data, it determines whether the data reading was successful. If the reading is successful, it requests the MES outbound result of the cell code from the MES. After obtaining the MES outbound result, it sends the MES outbound result and the corresponding cell code to the PLC. After receiving the MES outbound result and the cell code, the PLC adds the outbound mark corresponding to the MES outbound result to the cell code. At the same time, when the PLC receives the trigger verification signal, it reads the target outbound mark on the target cell code corresponding to the trigger verification signal, and then determines whether the target cell corresponding to the target cell code can be outbound normally based on the read target outbound mark.

[0056] Specifically, since the cells leaving this process are sequentially dispatched, each dispatched cell triggers a dispatch trigger signal to host computer 1. Assuming host computer 1 needs to read the cell code for each dispatched cell, and only after successfully reading it and requesting the dispatch result from MES before releasing the current dispatched cell, and then repeating this process for the next dispatched cell, the significant time gap between host computer 1's requests to MES will cause... The increased cycle time of this process reduces the efficiency of cell exiting the station. Therefore, this application, upon successful reading of the cell code by the host computer 1, releases the cell for exiting the station and proceeds to read the cell code of the next cell to exit. Simultaneously, the host computer 1 requests the MES exit result from the MES based on the scanned cell code and sends the corresponding MES exit result and cell code to the PLC. The PLC adds an exit marker to the cell code based on the MES exit result. Therefore, the PLC only needs to receive a touch... When a verification signal is sent, the target cell code for which the verification signal is triggered is determined. Then, the target outbound marker pre-added to the target cell code is read from the target cell code, and the judgment is made based on the target outbound marker. Based on this, since the cell needs to determine whether it can leave the station normally based on the outbound result requested from the preset management platform when leaving the station, there is a certain waiting time for the outbound result to be returned when requesting the preset management platform. At this time, the outbound cycle of the cell will increase. The cell outbound method proposed in this application is an asynchronous outbound method. When the cell leaves the station, the cell code is read and the cell is released. The outbound operation is performed on the next cell. At the same time, the outbound result of the preset management platform is requested based on the cell code. The outbound result of the preset management platform only needs to be received before the cell runs to the next process, that is, before the trigger verification signal is received. Thus, this application can save the time waiting for the preset management platform when the cell leaves the station and improve the outbound efficiency of the cell.

[0057] In some embodiments of this application, such as Figure 2 As shown, the cell outgoing system 0 also includes a detection device 3; wherein: the detection device 3 is used to detect whether the outgoing cell has reached the target outgoing position. If it has, it sends a cell arrival signal to the control device 2; the control device 2 is used to respond to the received cell arrival signal, determine whether the outgoing cell has successfully entered the target process, and if it has successfully entered the process, add the process data of the target process to the cell process data associated with the cell code of the outgoing cell, and send an outgoing trigger signal for the cell code to the host computer 1; if it has failed to enter the process, it does not send an outgoing trigger signal for the cell code to the host computer 1.

[0058] It should be noted that, in this embodiment, the detection device 3 is a sensor at the target exit position on the production line, used to detect the exiting cells on the production line; the specific detection device 3 can be selected according to the actual situation, and this embodiment does not make specific limitations here.

[0059] Specifically, when a sensor at the target exit position on the production line detects that a battery cell has arrived at the target exit position, it sends a battery cell arrival signal to the PLC. After receiving the battery cell arrival signal, the PLC obtains the entry information of the battery cell when it enters the target process, and determines whether the battery cell has successfully entered the target process. If the entry is successful, the process data of the target process is added to the battery cell process data associated with the battery cell code of the battery cell, and an exit trigger signal for the battery cell code is sent to the host computer 1. When the host computer 1 receives the exit trigger signal, it reads the battery cell code and requests the exit result from the MES. If the entry is unsuccessful, no exit trigger signal for the battery cell code is sent to the host computer 1.

[0060] In some embodiments of this application, the control device 2 is also used to respond to the received cell code and the preset management platform outbound result. If the preset management platform outbound result indicates that the outbound cell can be outbound normally, a first outbound mark is added to the cell code; if the preset management platform outbound result indicates that the outbound cell cannot be outbound normally, a second outbound mark is added to the cell code.

[0061] Specifically, after requesting the MES outbound result corresponding to the cell code from the MES, the host computer 1 sends the MES outbound result and the corresponding cell code to the PLC. After receiving the MES outbound result, the PLC adds an outbound flag to the cell code according to the MES outbound result. For example, if the MES outbound result is 0, it indicates that the cell can be outbound normally, and a first outbound flag, such as 1, can be added to the cell code. If the MES outbound result is any number other than 0, it indicates that the cell cannot be outbound normally, and a second outbound flag, such as 2, can be added to the cell code.

[0062] In some embodiments of this application, such as Figure 3 As shown, the battery cell exit system 0 also includes a target gripper device 4; wherein: the control device 2 is further configured to send a first instruction to the target gripper device 4 if the target exit mark is a first exit mark, and send a second instruction to the target gripper device 4 if the target exit mark is a second exit mark; the target gripper device 4 is configured to, in response to the received first instruction, transfer the target exit battery cell to the normal unloading conveyor belt, so that the normal unloading conveyor belt can transport the target exit battery cell to the next process; the target gripper device 4 is configured to, in response to the received second instruction, transfer the target exit battery cell to the abnormal unloading conveyor belt, so that the abnormal unloading conveyor belt can transport the target exit battery cell to the defective battery cell placement area.

[0063] It should be noted that, in the embodiments of this application, the target gripper device 4 can be a mechanical / electric gripper used to move the outgoing battery cell; the specific target gripper device 4 can be determined according to the actual situation, and this embodiment of the application does not make specific limitations here.

[0064] It should be noted that, in this embodiment of the application, the defective cell placement area is a No Good (NG) area, which is an area where defective cells are stored during the battery production process; the specific defective cell placement area can be determined according to the actual situation, and this embodiment of the application does not make specific limitations here.

[0065] Specifically, the target battery cell moves via a conveyor belt on the production line during the target process. After completing the target process and moving to the target exit position, the target battery cell's code is read by the host computer 1 upon reaching the target exit position. The host computer 1 then simultaneously requests the target MES exit result for the target battery cell code from the MES system and returns the target MES exit result and the target battery cell code to the PLC. Upon receiving this information, the PLC adds a corresponding target exit marker to the target battery cell code. During this process, the grippers on the production line move the target battery cell from the circular track to the accompanying track. As the grippers pick up the target battery cell, they send a trigger verification signal to the PLC. Therefore, the host computer 1 needs to return the target MES (Manufacturing Execution System) output result for that target battery cell to the PLC before the grippers place it onto the accompanying track. When the target battery cell is placed on the accompanying track and moves to the target transfer position, the sensor at that transfer position detects the arrival of a target battery cell and sends a signal to the PLC. Upon receiving a trigger verification signal, the PLC reads the target exit mark from the target cell code. If the target exit mark is the first exit mark, it indicates that the normal exit process can be performed on the target cell. The PLC then sends a first instruction to the grippers on the production line. Upon receiving the first instruction, the grippers transfer the target cell from the target transfer position to the normal unloading conveyor belt, which then transports the target cell to the entry position of the next process. If the target exit mark is the second exit mark, it indicates that the normal exit process cannot be performed on the target cell. In the process, the PLC sends a second instruction to the grippers on the production line. When the grippers receive the second instruction, they transfer the target battery cell from the target transfer position to the abnormal unloading conveyor belt. The abnormal unloading conveyor belt then transports the target battery cell to the NG yard. Based on this, it can be seen that at the target exit position, the battery cell only needs to be checked to see if the data reading was successful before it can continue to be transported through the production line. Only when it is transported to the target transfer position does it need to be checked by the MES exit result to see if the process flow of this target process has been completed and the battery cell has exited normally.

[0066] In some embodiments of this application, the host computer 1 is further configured to determine whether the outgoing battery cell corresponding to the battery cell code is the first outgoing battery cell. If the outgoing battery cell is the first outgoing battery cell, it requests the first-piece verification interface from the preset management platform so that the preset management platform can perform outgoing verification on the battery cell code based on the first-piece verification interface and obtain the outgoing result of the preset management platform. The host computer 1 is also configured to request the normal verification interface from the preset management platform if the outgoing battery cell is not the first outgoing battery cell, so that the preset management platform can perform outgoing verification on the battery cell code based on the normal verification interface and obtain the outgoing result of the preset management platform. The battery cell code setting rules for the first outgoing battery cell and non-first outgoing battery cells are different.

[0067] It should be noted that in this embodiment of the application, when the production line is first started, it needs to produce the first battery cell to test whether the production line is normal. The battery cell code setting rules for the first battery cell and non-first battery cells are different. The first battery cell often does not have a battery cell code. Therefore, the interface for requesting MES by the first battery cell and non-first battery cells is different.

[0068] Specifically, when the host computer 1 reads the cell code, if the outgoing cell does not have a cell code, then the outgoing cell is the first outgoing cell. The host computer 1 requests the first-piece verification interface corresponding to the first outgoing cell from the MES. The MES performs outgoing verification on the cell code through the first-piece verification interface and obtains the MES outgoing result. If the cell code of the outgoing cell is successfully read, then the outgoing cell is not the first outgoing cell. The host computer 1 requests the non-first-piece verification interface corresponding to the non-first outgoing cell from the MES. The MES performs outgoing verification on the cell code through the non-first-piece verification interface and obtains the MES outgoing result.

[0069] In some embodiments of this application, the host computer 1 is further configured to read the battery cell code from the control device 2 again and determine whether the data reading is successful again if the data reading is determined to be unsuccessful based on the battery cell code; the host computer 1 is further configured to send a reading failure indication message to the control device 2 if the data reading is determined to be unsuccessful for a preset number of consecutive times; the control device 2 is further configured to add a second outbound marker to the battery cell code in response to the received indication message.

[0070] It should be noted that in this embodiment, the preset number of attempts is set to 3. If the reading fails for 3 consecutive attempts, the reading is determined to have failed. The specific preset number of attempts can be set according to the actual situation, and this embodiment does not impose a specific limitation here.

[0071] Specifically, when the host computer 1 determines that the data reading is unsuccessful based on the cell code, it reads the cell code from the PLC again and checks whether the data reading is successful. If it is still unsuccessful, it continues to read the cell code from the PLC for judgment. If the judgment fails three times in a row, it sends a reading failure indication message to the PLC. Upon receiving the indication message, the PLC adds a second exit mark to the cell code, indicating that the cell cannot be exited normally, for example, mark 2. When the PLC subsequently receives a trigger verification signal for the cell code, it sends a second instruction to the gripper based on the second exit mark. The gripper then transfers the cell corresponding to the cell code to the abnormal unloading conveyor belt according to the second instruction. The abnormal unloading conveyor belt transports the cell to the NG yard.

[0072] In some embodiments of this application, the host computer 1 is further configured to send a warning signal to the control device 2 if multiple preset management platform outgoing results received consecutively indicate that the outgoing battery cell cannot leave the station normally; the control device 2 is further configured to respond to the received warning signal and generate corresponding alarm information; the alarm information includes at least the reason for triggering the alarm and the corresponding processing suggestions.

[0073] Specifically, if the host computer 1 receives multiple MES outgoing results for multiple cell codes that are not 0, it indicates that the corresponding multiple outgoing cells cannot be outgoing normally. At this time, an alarm message needs to be displayed on the screen of the host computer 1, and the on-site staff will decide whether to reactivate the system based on the alarm message.

[0074] This application provides a battery cell entry system 0, a host computer 1, and a control device 2. The host computer 1 is used to respond to a received exit trigger signal, read the battery cell code corresponding to the exit trigger signal from the control device 2, and, if it determines that the data reading was successful based on the battery cell code, request the exit result from the preset management platform corresponding to the battery cell code, and send the exit result and the battery cell code to the control device 2 so that the control device 2 can add an exit marker corresponding to the exit result of the preset management platform to the battery cell code. The control device 2 is used to respond to the received trigger signal. The verification signal is read, and the target departure mark on the target cell code corresponding to the trigger verification signal is read. Based on the target departure mark, it is determined whether to execute the normal departure process for the target cell code corresponding to the target cell code. Using the above implementation scheme, when the host computer determines that the cell code of the departing cell has been successfully read, it releases the departing cell and reads the cell code of the next departing cell. Simultaneously, the host computer requests the departure result from the preset management platform according to the scanned cell code, and sends the departure result and the corresponding cell code from the preset management platform to the control device, controlling... The equipment adds an outbound marker to the cell code based on the outbound result from the preset management platform. Therefore, the control equipment only needs to determine the target cell code for the trigger verification signal upon receiving it, then read the pre-added target outbound marker from the target cell code, and make a judgment based on the target outbound marker. However, since the cell needs to determine whether it can leave the station normally based on the outbound result requested from the preset management platform, there is a certain waiting time for the outbound result to be returned when requesting the preset management platform. The waiting time for the result will increase the cell departure cycle time. The cell departure method proposed in this application is an asynchronous departure method. When a cell leaves the station, the cell code is read and the cell is released. The departure operation is performed on the next cell. At the same time, the departure result of the preset management platform is requested based on the cell code. The departure result of the preset management platform only needs to be received before the cell runs to the next process, that is, before the trigger verification signal is received. Thus, this application can save the time of waiting to request the preset management platform when the cell leaves the station, and improve the departure efficiency of the cell.

[0075] In addition, this application embodiment also provides a battery production line, which includes a cell exit system, production equipment and transfer equipment. The production equipment is used to produce exit cells, and the transfer equipment is used to remove the exit cells from the production equipment and place them in the cell exit system, or to remove the exit cells from the cell exit system and transfer them to the target workstation.

[0076] In this embodiment of the application, the production equipment is used to produce outgoing battery cells. For example, the production equipment can be an assembly equipment that assembles outgoing battery cells into a housing, or it can be a welding equipment that connects multiple outgoing battery cells in the housing. Depending on the process sequence, the production equipment can take many different forms.

[0077] In this application embodiment, the transfer device can take many possible forms. For example, the transfer device is a conveyor belt, which has a simple structure and high transportation efficiency. Another example is an arm robot, which can perform more complex operations.

[0078] In this embodiment, the target station can be of various kinds. For example, the target station can be the assembly station for the outgoing battery cells. Specifically, before testing, the cover plate in the outer casing is not installed. The outgoing battery cells that have been welded will be transported to the target location by the transfer equipment for the installation of the cover plate. Another example is that the target station is a testing station, such as vibration testing, high temperature testing, etc. Yet another example is that the target station is a recycling station. When the outgoing battery cells are unqualified, the transfer equipment will transport them to the recycling station.

[0079] Based on the above embodiments, in another embodiment of this application, a cell outbound method is provided, applied to a cell outbound system 0, referenced. Figure 1 The battery cell outgoing system 0 includes a host computer 1 and control equipment 2. Figure 4 This application provides a flowchart illustrating a method for battery cell delivery, which includes the following steps S101 to S104:

[0080] Step S101: The host computer presents the outgoing display interface, which includes a cell outgoing display frame and a preset management platform outgoing result display frame.

[0081] It should be noted that, in this embodiment of the application, the outbound display interface is the graphical user interface (GUI) of the host computer 1, which is used to display the corresponding information; the specific image display interface can be determined according to the actual situation, and this embodiment of the application does not make specific limitations here.

[0082] For example, such as Figure 5 As shown, the battery cell departure display box 5 displays the departure trigger status of the departing battery cell, such as whether it can leave the station normally.

[0083] For example, such as Figure 5 As shown, the pre-set management platform outbound result display box 6 displays the log information of the outbound battery cells, such as operation log, MES log, error log, inbound verification AB side log, outbound log, inbound AB side NG log, outbound NG log, and MES outbound result, etc.

[0084] Step S102: The host computer responds to the received outbound trigger signal, reads the cell code corresponding to the outbound trigger signal from the control device; and if it determines that the data reading is successful based on the cell code, it requests the outbound result of the preset management platform corresponding to the cell code from the preset management platform, and displays the outbound result of the preset management platform in the outbound result display box of the preset management platform.

[0085] It should be noted that, in this embodiment of the application, the outgoing trigger signal is the outgoing trigger signal sent by the control device 2 to the host computer 1 for the cell code of the outgoing cell when it determines that the outgoing cell has successfully entered the target process. When the host computer 1 receives the outgoing trigger signal sent by the control device 2, it reads the cell code of the outgoing cell from the control device 2, and when the reading is successful, it requests the preset management platform outgoing result of the cell code, i.e., the MES outgoing result, from the preset management platform.

[0086] For example, such as Figure 5 As shown, after successfully reading the cell code of the incoming battery cell, the host computer 1 can display the cell code in the cell code display box 7, then request the MES outgoing result for the cell code, and then display the MES outgoing result in N.

[0087] It should be noted that, in this embodiment of the application, when the host computer 1 determines whether the data reading is successful, it is to determine whether the read cell code is accurate. For example, it can determine whether the read cell code is accurate by using rules such as the number of barcode digits of the cell code, so as to avoid affecting the efficiency of subsequent cell exit due to failure to read the cell code.

[0088] Step S103: The host computer sends the preset management platform outbound result and cell code to the control device, so that the control device can add the outbound mark corresponding to the preset management platform outbound result to the cell code.

[0089] It should be noted that, in this embodiment of the application, after the host computer 1 requests the outbound result from the preset management platform, it sends the cell code and the outbound result from the preset management platform to the control device 2. After receiving the outbound result from the preset management platform and the cell code, the control device 2 adds an outbound flag corresponding to the outbound result from the preset management platform to the cell code. If the outbound result from the preset management platform indicates that the outbound cell can leave the station normally, a first outbound flag is added to the cell code; if the outbound result from the preset management platform indicates that the outbound cell cannot leave the station normally, a second outbound flag is added to the cell code.

[0090] Step S104: The control device responds to the received trigger verification signal, reads the target outbound mark on the target cell code corresponding to the trigger verification signal, displays the target outbound mark in the cell outbound display box, and determines whether to perform the normal outbound process for the target cell code corresponding to the target outbound cell based on the target outbound mark.

[0091] It should be noted that, in this embodiment of the application, when the control device 2 receives the trigger verification signal, it reads the target outbound marker pre-added on the target cell code corresponding to the trigger verification signal, and then determines whether the target outbound cell can leave the station normally based on the read target outbound marker. If the target outbound marker is the first outbound marker, the target outbound cell can leave the station normally; if the target outbound marker is the second outbound marker, the target outbound cell cannot leave the station normally.

[0092] For example, such as Figure 5 As shown, if the outgoing battery cell cannot execute the normal outgoing process, NG will be displayed in the battery cell outgoing display box 5; if the outgoing battery cell can execute the normal outgoing process, OK will be displayed in the battery cell outgoing display box 5.

[0093] In some embodiments of this application, such as Figure 2 As shown, the cell exit system 0 also includes a detection device 3; when the detection device 3 detects that the cell has reached the target exit position, it sends a cell arrival signal to the control device 2. When the control device 2 receives the cell arrival signal, it determines whether the cell has successfully entered the target process. If the cell has successfully entered the process, it adds the process data of the target process to the cell process data associated with the cell code of the cell and sends an exit trigger signal for the cell code to the host computer 1. If the cell has not successfully entered the process, it does not send an exit trigger signal for the cell code to the host computer 1.

[0094] like Figure 6 The diagram illustrates an exemplary process for triggering an outbound trigger signal, as shown in steps S201 to S206:

[0095] Step S201: The outgoing battery cell moves to the target outgoing position through the production line.

[0096] Step S202: The testing equipment on the production line checks whether the outgoing battery cells have reached the target outgoing position.

[0097] Step S203: If the cell arrives, send a cell arrival signal to the control device.

[0098] Step S204: The control equipment responds to the received cell arrival signal and determines whether the cell has successfully entered the target process.

[0099] Specifically, if yes, that is, there is no NG (Not Acceptable) entry, then exit is triggered, i.e., proceed to step S205; if no, that is, NG entry, then exit is not triggered, and proceed to step S206.

[0100] Step S205: Add the process data of the target process to the cell process data associated with the cell code of the outgoing cell, and send an outgoing trigger signal for the cell code to the host computer.

[0101] Specifically, assuming the target process is welding, the process data such as cell welding for the welding process are added to the cell process data, and then an outgoing trigger signal is sent to the host computer 1.

[0102] Step S206: Do not send an outbound trigger signal for the cell code to the host computer.

[0103] In some embodiments of this application, after receiving the outbound trigger signal sent by the control device 2, the host computer 1 reads the cell code and invokes the asynchronous outbound process, such as... Figure 7 The diagram illustrates an exemplary process for asynchronous battery cell delivery, where the PLC represents the control device 2 in this application, and the MES represents the pre-defined management platform in this application; specifically, steps S301 to S310 are shown below:

[0104] Step S301: The host computer software initialization is completed, the PLC connection is successful, and the outbound process is started.

[0105] Step S302: The host computer reads the outgoing trigger signal sent by the PLC.

[0106] Step S303: The PLC sets the outgoing station trigger signal to true.

[0107] Specifically, the outbound trigger signal address is of type boolean, true: trigger, false: do not trigger.

[0108] Step S304: The host computer reads the cell code corresponding to the outgoing station trigger signal from the PLC.

[0109] Step S305: The host computer determines whether the data reading was successful based on the cell code.

[0110] Specifically, if the data reading is successful, proceed to step S306; if the data reading is unsuccessful, proceed to step S305 to reread the data; if the data reading is still unsuccessful after 3 attempts, proceed to step S309.

[0111] Step S306: The host computer asynchronously requests the MES outbound result corresponding to the cell code from the MES.

[0112] Step S307: The host computer sends the MES outgoing results and corresponding cell codes to the PLC.

[0113] Step S308: The PLC receives the MES outbound result and adds an outbound marker to the cell code based on the MES outbound result.

[0114] Specifically, if the preset management platform's outbound result indicates that the outbound cell can leave the station normally, then a first outbound marker is added to the cell code; if the preset management platform's outbound result indicates that the outbound cell cannot leave the station normally, then a second outbound marker is added to the cell code.

[0115] Step S309: The PLC receives the reading failure indication information sent by the host computer and adds an outgoing mark to the cell code according to the indication information.

[0116] Specifically, when the PLC receives the instruction information, it adds a second outbound marker to the cell code, indicating that the cell cannot be shipped out normally.

[0117] In step S310, after the PLC adds a marker to the cell code, it sets the outgoing trigger signal to false.

[0118] Based on the above embodiments, after receiving the outbound trigger signal sent by the PLC, the host computer 1 begins to read the cell code and cell process data corresponding to the outbound trigger signal from the PLC. If the reading is successful, the outbound cell is allowed to proceed, and the data reading process for the next outbound cell is started. At the same time, the asynchronous outbound process of the MES is invoked to request the MES outbound result of the cell code from the MES. After obtaining the MES outbound result, the MES outbound result and the corresponding cell code are sent to the PLC. The PLC adds a first outbound marker or a second outbound marker to the cell code according to the MES outbound result. If the reading fails three times, the outbound cell is also allowed to proceed, and the data reading process for the next outbound cell is started. The host computer 1 sends a reading failure indication message and the cell code to the PLC. The PLC adds a second outbound marker to the cell code according to the indication message.

[0119] It should be noted that in this embodiment of the application, the cells that cannot leave the station normally are not discharged at the target exit position, but are discharged at the entrance of the next process. Therefore, at the target exit position, the host computer 1 only needs to be able to successfully read the cell code and cell process data to indicate that the exit is successful. The MES call will be performed asynchronously, ensuring that the efficiency of cell exit is not affected by the MES call.

[0120] In some embodiments of this application, the host computer 1 determines whether the outgoing battery cell corresponding to the battery cell code is the first outgoing battery cell. If the outgoing battery cell is the first outgoing battery cell, it requests the first-piece verification interface from the preset management platform so that the preset management platform can perform outgoing verification on the battery cell code based on the first-piece verification interface, obtain the outgoing result of the preset management platform, and display the outgoing result of the preset management platform in the outgoing result display box of the preset management platform. If the outgoing battery cell is not the first outgoing battery cell, it requests the normal verification interface from the preset management platform so that the preset management platform can perform outgoing verification on the battery cell code based on the normal verification interface, obtain the outgoing result of the preset management platform, and display the outgoing result of the preset management platform in the outgoing result display box of the preset management platform. The battery cell code setting rules are different for the first outgoing battery cell and non-first outgoing battery cells.

[0121] For example, such as Figure 5 As shown, after the host computer 1 requests the MES outbound result from the MES, regardless of whether the outbound cell is the first one, the MES outbound result will be displayed in the preset management platform outbound result display box 6.

[0122] Based on the above embodiments, such as Figure 8 The diagram illustrates an exemplary process for requesting outbound results from the MES (Management Execution System). In the diagram, the MES is the pre-defined management platform of this application, and the PLC is the control device 2 of this application. Specifically, steps S401 to S411 are shown below:

[0123] Step S401: The host computer successfully reads the cell code from the PLC.

[0124] Step S402: The host computer determines whether the battery cell corresponding to the battery cell code is the first battery cell to leave the station.

[0125] Specifically, if the outgoing battery cell is the first outgoing battery cell, proceed to step S403; if the outgoing battery cell is not the first outgoing battery cell, proceed to step S404.

[0126] Step S403: The host computer requests the first item verification interface from the MES.

[0127] Step S404: The host computer verifies whether the cell code conforms to the standard.

[0128] Specifically, if the condition is met, proceed to step S405; otherwise, proceed to step S409.

[0129] Step S405: The host computer requests the normal verification interface from the MES.

[0130] Step S406: MES performs outbound verification of the cell code based on the first-piece verification interface / normal verification interface to obtain the MES outbound result.

[0131] Step S407: MES returns the MES outbound results to the host computer.

[0132] Step S408: The host computer receives the MES outbound result and determines whether the MES verification is OK.

[0133] Specifically, if the MES verification is OK, proceed to step S409; if the verification is not OK, proceed to step S410.

[0134] Step S409: The host computer writes the MES outgoing results into the production data log and sends them to the PLC.

[0135] Specifically, after receiving the MES outbound result of the cell code, the host computer writes the MES outbound result into the production data log to facilitate subsequent data traceability, and sends the cell code and MES outbound result to the PLC so that the PLC can add the corresponding outbound mark to the cell code according to the MES outbound result.

[0136] Step S410: The host computer determines whether a PLC alarm and shutdown are required based on the MES outgoing results returned by the MES.

[0137] Specifically, if a PLC alarm shutdown is required, proceed to step S411; if a PLC alarm shutdown is not required, proceed to step S409.

[0138] Step S411: The PLC receives the warning signal sent by the host computer, stops the machine according to the warning signal, and generates alarm information.

[0139] Based on the above embodiments, after the host computer 1 responds to the outbound trigger signal sent by the PLC and successfully reads the cell code from the PLC, it determines whether the outbound cell corresponding to the cell code is the first outbound cell or a non-first outbound cell (i.e., a normal cell). If it is a non-first outbound cell (i.e., a normal cell), it is also necessary to verify whether the cell code conforms to the standard, such as whether the length of the cell code and the first few digits of the cell code are the same as the preset values. If it is the first outbound cell, since the first outbound cell has no cell code, there is no need to verify the cell code. Furthermore, if it is a non-first outbound cell, the normal verification interface is called. If it is the first outbound cell... Then, the first-piece verification interface is called, and the MES performs logical judgment to verify whether the target process of the outgoing battery cell is normal, whether the outgoing battery cell has NC, whether the process data of the outgoing battery cell is complete, or whether the process data exceeds the upper and lower limits, etc. After the verification is completed, the MES returns the MES outgoing result to the host computer. Among them, the MES returns 0 to indicate that the verification is passed and the outgoing battery cell can be outgoing normally. The MES returns any number other than 0 to indicate that the verification is failed and the outgoing battery cell cannot be outgoing normally, i.e., NG. If an NG occurs, the host computer's self-diagnosis system will automatically pop up a window to prompt the on-site staff for the reason why the outgoing battery cell cannot be outgoing normally.

[0140] In some optional embodiments of this application, the outbound display interface further includes an early warning interface, and the method further includes: if the host computer 1 continuously receives multiple preset management platform outbound results indicating that the outbound battery cell cannot leave the station normally, it sends an early warning signal to the control device 2, so that the control device 2 responds to the received early warning signal and generates corresponding alarm information to send to the host computer 1; the alarm information includes at least the reason for triggering the alarm and the corresponding handling suggestions; the host computer 1 responds to the received alarm information and displays the alarm information on the early warning interface.

[0141] Specifically, if three consecutive NG (Not Okay) errors occur, the host computer 1 will send a warning signal to the PLC, notifying the PLC that three consecutive NG errors have occurred. Upon receiving the warning signal, the PLC will immediately stop the machine, generate alarm information, and display it on the host computer's warning interface. The system will then wait for on-site personnel to determine the cause before deciding whether to restart the machine. In some other cases, the machine needs to be stopped after just one error. For example, if the MES system returns 13033, it means the machine is locked on the MES; 13473 means insufficient electronic materials; -1 means the MES is offline; and 13043 means insufficient production work orders. These situations require immediate shutdown after just one error, and the corresponding alarm information will be displayed on the host computer's warning interface. The system will then wait for on-site personnel to resolve the problem before deciding whether to restart the machine.

[0142] For example, such as Figure 9 As shown, the early warning interface 8 may include an alarm time display box 81, an alarm interface name display box 82, an error code display box 83, an error reason display box 84 (the reason for triggering the alarm), a handling method display box 85, a handling suggestion display box 86, a handling person display box 87, and an upload handling suggestion display box 88, etc., to notify on-site staff of system problems so that on-site staff can handle them in a timely manner.

[0143] In some optional embodiments of this application, such as Figure 10 As shown, the outbound display interface may also include a first connection status display box 9, a file location display box 10, and a second connection status display box 11; wherein, the first connection status display box 9 is used to display the connection status with the control device 2; the file location display box 10 is used to display open icons for logs such as outbound log, barcode scanning log, MES log, first item log, operation log, running log, touch screen alarm log, and touch screen operation log, and the user can open the corresponding log by clicking the corresponding icon; the second connection status display box 11 is used to display the connection status with multiple barcode scanners.

[0144] It is understandable that, such as Figure 11The diagram illustrates an exemplary process for a battery cell leaving the production line. As shown, battery cells completing the target process sequentially reach the target exit position 13 via a conveyor belt on the production line. When a sensor at target exit position 13 detects a battery cell arriving at the target exit position, it sends a battery cell arrival signal to the PLC. Upon receiving the signal, the PLC obtains the battery cell's entry information when entering the target process, determining whether the battery cell has successfully entered the target process. If entry is successful, the PLC adds the target process data to the battery cell process data associated with the battery cell code and sends an exit trigger signal for the battery cell code to the host computer 1. The host computer 1 then reads the battery cell code from the PLC based on the exit trigger signal. If the cell code is successfully read, the current cell is released for departure, and the cell code is read for the next cell to leave the station. Simultaneously, the host computer 1 requests the MES exit result from the MES based on the read cell code, and sends the MES exit result and cell code correspondence to the PLC. The PLC adds an exit mark to the cell code based on the MES exit result. After the cell code is read by the host computer 1 at the target exit position 13, the grippers on the production line clamp the target cell from the ring track 12 to the accompanying track 14. When the grippers pick up the target cell, they send a trigger verification signal to the PLC. Therefore, the host computer 1 needs to return a target value for the target cell to the PLC before the grippers place the target cell onto the accompanying track 14. According to the MES outbound result, when the target outbound battery cell is placed on the accompanying conveyor belt 14 and moves to the target transfer position 15, the sensor located at the target transfer position 15 detects the arrival of a target outbound battery cell and sends a trigger verification signal to the PLC. The PLC reads the target outbound mark from the target battery cell code. If the outbound mark is the first outbound mark, it indicates that the normal outbound process can be performed on the outbound battery cell. The PLC then sends a first instruction to the gripper on the production line. Upon receiving the first instruction, the gripper transfers the target outbound battery cell from the target transfer position 15 to the normal unloading conveyor belt 16. The normal unloading conveyor belt 16 transports the outbound battery cell to the inbound position of the next process. If the outbound mark is the second outbound mark... If the normal outbound process cannot be performed on the outbound battery cell, the PLC sends a second instruction to the gripper on the production line. When the gripper receives the second instruction, it transfers the outbound battery cell from the target transfer position to the abnormal unloading conveyor belt 17. The abnormal unloading conveyor belt 17 then transports the outbound battery cell to the NG field 18. It can be seen that at the target outbound position 13, the outbound battery cell only needs to be checked to see if the data reading was successful before it can continue to be transported through the production line. Only when it is transported to the target transfer position 15 does it need to be checked through the MES outbound result to see if the process flow of this target process has been completed and the battery cell has been normally outbound. That is, the asynchronous outbound method proposed in this application can save the time of waiting for the MES outbound result, reduce the time cycle, and improve the outbound efficiency of the battery cell.

[0145] This application provides a method for battery cell outbound processing, applied to a battery cell outbound system. The system includes a host computer and a control device. The method includes: the host computer responding to a received outbound trigger signal, reading the battery cell code corresponding to the outbound trigger signal from the control device; and, if the data reading is successful based on the battery cell code, requesting the outbound result from the preset management platform corresponding to the battery cell code, and sending the preset management platform outbound result and the battery cell code to the control device so that the control device can add an outbound marker corresponding to the preset management platform outbound result to the battery cell code; the control device responding to a received trigger verification signal, reading the target outbound marker on the target battery cell code corresponding to the trigger verification signal, and determining whether to perform a normal outbound process for the target battery cell corresponding to the target outbound battery cell code based on the target outbound marker; using the above implementation scheme, this application... Once the host computer determines that the cell code of the outgoing cell has been successfully read, it releases the outgoing cell and begins reading the cell code of the next outgoing cell. Simultaneously, the host computer requests the outgoing result from the preset management platform based on the scanned cell code, and sends the corresponding outgoing result and cell code to the control device. The control device adds an outgoing marker to the cell code based on the outgoing result from the preset management platform. Therefore, the control device only needs to determine the target cell code for the trigger verification signal upon receiving it, then read the pre-added target outgoing marker from the target cell code, and make a judgment based on the target outgoing marker. The cell outgoing method proposed in this application is an asynchronous outgoing method, which saves the time spent waiting to request the preset management platform and improves the outgoing efficiency of the cells.

[0146] This application also provides a computer-readable storage medium storing a computer program thereon. The computer-readable storage medium stores one or more programs, which can be executed by one or more processors and applied to a battery cell dispatching system. The computer program implements the battery cell dispatching method described above.
