[0002] In order to improve the assembly efficiency of battery cells, a control system is usually used to realize the automated assembly of battery cells. In related technologies, a dual physical control system is usually adopted, such as a control device equipped with a time-sharing operating system and a hard PLC control system, to realize the automated assembly of battery cells. Among them, the hard PLC control system refers to hardware or a dedicated ASIC chip to implement the execution of PLC instructions. However, this method requires the configuration of at least two control devices, and the hard PLC control system needs to be based on dedicated hardware. It is difficult to build an open hardware system, and the hardware expansion and upgrade are relatively difficult. Components from specific manufacturers are required, resulting in high cost of the control system for battery cell assembly. Utility Model Content

[0003] In view of the above problems, the present application provides a control system for battery cell assembly, which can reduce the cost of the control system.

[0004] In a first aspect, an embodiment of the present application provides a control system for battery cell assembly, comprising a dual-system industrial computer equipped with a time-sharing operating system and a real-time operating system, and a controlled device for performing battery cell assembly; the dual-system industrial computer comprises a first core for running the time-sharing operating system, and a second core for running the real-time operating system, the first core and the second core are communicatively connected, and the first core and the second core each include at least one processor core; the controlled device is communicatively connected to the second core.

[0005] In the technical solution of the embodiment of the present application, since the first core of the dual-system industrial computer runs a time-sharing operating system and the second core runs a real-time operating system, it is only necessary to deploy corresponding programs in the time-sharing operating system and the real-time operating system, respectively. For example, deploying the programming software of the soft PLC in the time-sharing operating system and deploying the logic motion control program of the soft PLC in the real-time operating system, can control the controlled equipment to perform battery cell assembly through the processor core of a single dual-system industrial computer, eliminating the need to configure multiple physical control systems and the need to use a dedicated ASIC chip to execute PLC instructions, thereby reducing the hardware cost of the control system. At the same time, since the real-time operating system runs on the processor core of the dual-system industrial computer, the real-time operating system can fully utilize the resources of the processor core, thereby increasing the speed of data processing and thus improving the efficiency of battery cell assembly.

[0006] In some embodiments, the controlled device includes a driving component and a sensing component; the dual-system industrial computer includes an EtherCAT coupler and an Ethernet / IP coupler connected to the second core; the driving component is connected to the EtherCAT coupler, the sensing component is connected to the Ethernet / IP coupler, and the driving component is connected to an execution component for performing battery cell assembly operations, thereby improving the versatility of the control system while improving the battery cell assembly efficiency.

[0007] In some embodiments, the drive component includes at least one I / O module and at least one servo drive; each I / O module and each servo drive is connected to the EtherCAT coupler, and each servo drive is connected to a corresponding actuator. This allows each servo drive to drive the actuator for cell assembly, while each I / O module enables the EtherCAT coupler to support a wider range of input and output signal types, thereby meeting various complex industrial automation requirements. This not only increases the practicality and flexibility of the control system, but also improves the system's configurability and scalability.

[0008] In some embodiments, the drive component includes at least one I / O module and at least one servo drive. Each I / O module and each servo drive are connected to the EtherCAT coupler in a daisy-chain mode to form a daisy chain. Each servo drive is connected to a corresponding actuator. This improves the configurability and scalability of the system through the use of I / O modules while reducing the complexity of cable connections and avoiding bus contention and signal blocking.

[0009] In some embodiments, the drive component includes at least one I / O module and at least one servo drive. The input of each I / O module is connected to the EtherCAT coupler, and the input of any servo drive is connected to the output of the I / O module or the output of another servo drive. Each servo drive is connected to a corresponding execution component. This allows the I / O modules to improve the configurability and scalability of the system while reducing the possibility of bus contention and signal blocking.

[0010] In some embodiments, the sensing component includes a barcode scanner and a pressure sensor; the barcode scanner and the pressure sensor are connected to the Ethernet / IP coupler.

[0011] In some embodiments, the control system further includes a detection component for performing pressure detection; the detection component is connected to the pressure sensor and the Ethernet / IP coupler, so that the detection component can be used to determine whether the pressure of the battery cell assembly environment meets the requirements.

[0012] In some embodiments, the number of processor cores of the second core is greater than the number of processor cores of the second core, thereby enabling more efficient control of the controlled device to perform battery cell assembly, thereby improving battery cell assembly efficiency.

[0013] In some embodiments, the control system further includes an MES server, which is communicatively connected to the first kernel. The MES server can thus be used to track and monitor the battery cell assembly process in real time, enabling management personnel to obtain real-time production data and information and respond promptly.

[0014] In some embodiments, the dual-system industrial computer further includes a display, and the display is used to display a human-computer interaction interface deployed by the time-sharing operating system. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] Currently, to improve battery cell assembly efficiency, control systems are often used to automate the assembly of battery cells. Related technologies typically employ dual physical control systems to achieve this. For example, a control device equipped with a time-sharing operating system is connected to a hard-wired PLC control system. The hard-wired PLC control system is connected to each controlled device used for battery cell assembly via a motion control board. This allows for automated assembly of battery cells through the control device and the hard-wired PLC control system. A hard-wired PLC control system refers to hardware or a dedicated ASIC chip that executes PLC instructions.

[0032] However, this approach requires the configuration of at least two control devices, and the hard PLC control system needs to be based on dedicated hardware, making it difficult to build an open hardware system. Hardware expansion and upgrades are relatively difficult and require components from specific manufacturers, resulting in high costs and poor versatility of the control system used for battery cell assembly.

[0033] In response to the above technical problems, an embodiment of the present application provides a control system for battery cell assembly, including a dual-system industrial computer equipped with a time-sharing operating system and a real-time operating system, and a controlled device for battery cell assembly; the dual-system industrial computer includes a first core for running the time-sharing operating system, and a second core for running the real-time operating system, the first core and the second core are communicatively connected, and the first core and the second core each include at least one processor core; the controlled device is communicatively connected to the second core. Since the first core of the dual-system industrial computer runs the time-sharing operating system and the second core runs the real-time operating system, it is only necessary to deploy corresponding programs in the time-sharing operating system and the real-time operating system respectively, such as deploying the programming software of the soft PLC in the time-sharing operating system and deploying the logical motion control program of the soft PLC in the real-time operating system, so that the controlled device can be controlled to perform battery cell assembly through the processor core of a dual-system industrial computer, without configuring multiple physical control systems and without using dedicated ASIC chips to implement the execution of PLC instructions, thereby reducing the hardware cost of the control system. At the same time, since the real-time operating system runs on the processor core of the dual-system industrial computer, the real-time operating system can make full use of the resources of the processor core, thereby increasing the speed of data processing and further improving the efficiency of battery cell assembly.

[0034] According to some embodiments of the present application, a control system for battery cell assembly is provided, such as Figure 1 As shown, the control system for battery cell assembly includes a dual-system industrial computer 10 equipped with a time-sharing operating system and a real-time operating system, and a controlled device 20 for performing battery cell assembly; the dual-system industrial computer 10 includes a first kernel 30 for running the time-sharing operating system, and a second kernel 40 for running the real-time operating system, the first kernel 30 and the second kernel 40 are communicatively connected, and the first kernel 30 and the second kernel 40 both include at least one processor core; the controlled device 20 is communicatively connected to the second kernel 40.

[0035] In some embodiments, the dual-system industrial computer 10 may be an industrial computer equipped with a time-sharing operating system and a real-time operating system, capable of running both the time-sharing operating system and the real-time operating system simultaneously within a single chassis. For example, the industrial computer may be equipped with a virtual machine running the time-sharing operating system and a virtual machine running the real-time operating system. The time-sharing operating system may be a Windows system, and the time-sharing operating system may be deployed with soft PLC programming software and a human-computer interaction interface, etc. The real-time operating system may be deployed with a soft PLC logic motion control program and an EtherCAT motion control program, etc., to implement functions such as sequential control, interlocking alarms, one-button initialization, and beat control.

[0036] The dual-system industrial computer 10 includes a first kernel 30 running a time-sharing operating system and a second kernel 40 running a real-time operating system. The first kernel 30 and the second kernel 40 may be composed of different processor cores in the central processing unit of the dual-system industrial computer 10. Exemplarily, the central processing unit of the dual-system industrial computer 10 is a multi-core processor comprising N processor cores, i.e., N physical cores. Of the N processor cores, n constitute the first kernel 30, and the remaining Nn constitute the second kernel 40, where n ≥ 1 and Nn ≥ 1. Since the first kernel 30 runs a time-sharing operating system, which can be deployed with soft PLC programming software and a human-computer interface, the first kernel 30 is equivalent to a control device equipped with a time-sharing operating system. The second kernel 40 runs a real-time operating system, which is deployed with the soft PLC's logical motion control program and the EtherCAT motion control program, and therefore the second kernel 40 is equivalent to an EtherCAT master controller.

[0037] To improve cell assembly efficiency, in some embodiments, the number of processor cores in the second core 40 is greater than the number of processor cores in the second core 40. For example, assuming the CPU of the dual-system industrial computer 10 is a quad-core processor, one of the processor cores can be used to form the first core 30, and the other two to three processor cores can be used to form the second core 40. This allows more processor cores to process motion control programs deployed on the real-time operating system, increasing data processing speed, thereby more efficiently controlling the controlled device 20 for cell assembly and improving cell assembly efficiency.

[0038] The first core 30 and the second core 40 are in communication, enabling data transmission and information exchange between the time-sharing operating system and the real-time operating system, allowing the time-sharing operating system and the real-time operating system to cooperate with each other to control the automated assembly of battery cells. For example, the first core 30 can execute an operating instruction of the real-time operating system, which can be sent to the real-time operating system of the second core 40, thereby controlling the controlled device 20 to perform the corresponding operation.

[0039] The input end of the controlled device 20 can be connected to the second core 40 via the EtherCAT bus for communication, and the output end of the controlled device 20 is used to access the execution component 105 that performs the battery cell assembly operation, such as a robot or a robotic arm. Exemplarily, the controlled device 20 may include a drive component 101, such as a servo driver 202. In this case, the controlled device 20 is equivalent to an EtherCAT slave station. When assembling battery cells, the controlled device 20 can receive the battery cell assembly instructions sent by the second core 40 running a real-time operating system, execute the battery cell assembly instructions, and drive the execution component 105 to perform the corresponding battery cell assembly operation, such as driving the robot to grab the battery cell and insert the battery cell into the shell.

[0040] A control system for battery cell assembly is provided, comprising a dual-system industrial computer 10 equipped with a time-sharing operating system and a real-time operating system, and a controlled device 20 for battery cell assembly. The dual-system industrial computer 10 includes a first core 30 for running the time-sharing operating system and a second core 40 for running the real-time operating system. The first core 30 and the second core 40 are communicatively connected, and each of the first core 30 and the second core 40 includes at least one processor core. The controlled device 20 is communicatively connected to the second core 40. Because the first core 30 of the dual-system industrial computer 10 runs the time-sharing operating system and the second core 40 runs the real-time operating system, it is only necessary to deploy corresponding programs in the time-sharing operating system and the real-time operating system, respectively. For example, deploying software program logic controller (PLC) programming software in the time-sharing operating system and deploying software program logic and motion control in the real-time operating system, the controlled device 20 can be controlled to perform battery cell assembly using the processor core of the dual-system industrial computer 10. This eliminates the need for multiple physical control systems and the need for dedicated ASIC chips to execute PLC instructions, thereby reducing the hardware cost of the control system. At the same time, since the real-time operating system runs on the processor core of the dual-system industrial computer 10, the real-time operating system can fully utilize the resources of the processor core, thereby increasing the speed of data processing and further improving the efficiency of battery cell assembly.

[0041] In some embodiments, as Figure 2 As shown, the controlled device 20 includes a driving component 101 and a sensing component 102; the dual-system industrial computer 10 includes an EtherCAT coupler 103 and an Ethernet / IP coupler 104 connected to the second core 40; the driving component 101 is connected to the EtherCAT coupler 103, the sensing component 102 is connected to the Ethernet / IP coupler 104, and the driving component 101 is connected to an execution component 105 that performs battery cell assembly operations.

[0042] The driving component 101 may be a servo driver 202, and the sensing component 102 may be a sensor, such as a photoelectric sensor or a pressure sensor 204. The input end of the driving component 101 is connected to the EtherCAT coupler 103 to access the second core 40 via the EtherCAT interface, and the output end of the driving component 101 is connected to the execution component 105 that performs the battery cell assembly operation. The sensing component 102 is connected to the Ethernet / IP coupler 104 to access the second core 40 via the Ethernet / IP interface. The sensing component 102 is used to collect data, upload the collected data to the second core 40 via the Ethernet / IP interface, and then send the collected data to the first core 30 via the second core 40, so that the data collected by the sensing component 102 can be displayed on the dual-system industrial computer 10 through the time-sharing operating system running on the first core 30.

[0043] Because the drive component 101 and the sensing component 102 have different real-time requirements, for example, the drive component 101 needs to perform operational control of battery cell assembly, which has higher real-time requirements than the sensing component 102. EtherCAT is a master-slave control communication protocol on Ethernet that can achieve very low latency and efficient bandwidth utilization. It is commonly used in high-performance machine control and motion control applications. Ethernet / IP provides more flexible network configuration and management options. Therefore, the drive component 101 can be connected to the second core 40 via the EtherCAT coupler 103 to improve the control accuracy of the drive component 101, and the sensing component 102 can be connected to the second core 40 via the Ethernet / IP coupler 104 to facilitate the configuration of the sensing component 102, thereby improving the efficiency of battery cell assembly while increasing the versatility of the control system.

[0044] To improve the configurability and scalability of the control system, in some embodiments, Figure 3a As shown, the drive component 101 includes at least one I / O module 201 and at least one servo drive 202;

[0045] Each of the I / O modules 201 and each of the servo drivers 202 is connected to the EtherCAT coupler 103 , and each of the servo drivers 202 is connected to a corresponding execution component 105 .

[0046] The inputs of each I / O module 201 and each servo driver 202 are connected to the EtherCAT coupler 103, and the outputs of each servo driver 202 are connected to corresponding actuators 105, such as manipulators or robotic arms. The I / O modules 201 may be EIM series I / O modules 201. The inputs of each I / O module 201 and each servo driver 202 may be connected to the EtherCAT coupler 103 via the same bus, or the inputs of each I / O module 201 and each servo driver 202 may be connected to the EtherCAT coupler 103 separately.

[0047] By connecting each I / O module 201 and each servo driver 202 to the EtherCAT coupler 103, and each servo driver 202 is connected to a corresponding actuator 105, each servo driver 202 can be used to drive the actuator 105 to assemble the battery cell. At the same time, each I / O module 201 can be used to enable the EtherCAT coupler 103 to support more input and output signal types, thereby meeting various complex industrial automation requirements. This not only increases the practicality and flexibility of the control system, but also improves the configurability and scalability of the system.

[0048] In order to improve the configurability and scalability of the system while reducing the complexity of cable connections, in some embodiments, such as Figure 3b As shown, each of the I / O modules 201 and each of the servo drivers 202 is connected to the EtherCAT coupler 103 in a daisy chain mode to form a daisy chain, and each of the servo drivers 202 is connected to a corresponding execution component 105 .

[0049] For example, each I / O module 201 and each servo drive 202 can serve as an EtherCAT slave and be connected to the EtherCAT coupler 103 in sequence using a daisy-chain connection. The connection order of each I / O module 201 and each servo drive 202 can be adjusted according to actual conditions. For example, at least one I / O module 201 can be connected between the servo drive 202 and the EtherCAT coupler 103, that is, the first EtherCAT slave connected to the EtherCAT coupler 103 can be the I / O module 201. Alternatively, at least one servo drive 202 can be connected between the I / O module 201 and the EtherCAT coupler 103, that is, the first EtherCAT slave connected to the EtherCAT coupler 103 can be the servo drive 202. At least one servo drive 202 can be connected between adjacent I / O modules 201. For example, if an I / O module 201 is connected to a servo drive 202, the servo drive 202 can be connected to another servo drive 202 or an I / O module 201. Alternatively, each I / O module 201 is sequentially connected to the input end of the EtherCAT coupler 103, and each servo drive 202 is sequentially connected to the last I / O module 201; or each servo drive 202 is sequentially connected to the EtherCAT coupler 103, and each I / O module 201 is sequentially connected to the last servo drive 202. Each servo drive 202 is also connected to a corresponding actuator 105 to control the actuator 105 to perform the cell assembly operation.

[0050] Since each I / O module 201 and each servo drive 202 are connected to the EtherCAT coupler 103 in daisy chain mode, limited signal lines can be used to connect each I / O module 201 and each servo drive 202 to share the services of the real-time operating system. This reduces the complexity of cable connections while improving the configurability and scalability of the system by utilizing the I / O modules 201, and avoids bus contention and signal blocking.

[0051] In some embodiments, as Figure 3c As shown, the input end of each I / O module 201 can also be connected to the EtherCAT coupler 103 , and the input end of any servo driver 202 can be connected to the output end of the I / O module 201 or the output end of another servo driver 202 .

[0052] For example, each I / O module 201 can be connected to the EtherCAT coupler 103 respectively, and the M servo drivers 202 in each servo driver 202 can be connected to a certain I / O module 201 in the form of a daisy chain connection, where M≥1. Figure 3cAs shown, three servo drives 202 can be connected to a single I / O module 201 in a daisy-chain fashion. The input of the first servo drive 202 is connected to the output of the I / O module 201, the output of the first servo drive 202 is connected to the input of the second servo drive 202, and the output of the second servo drive 202 is connected to the input of the third servo drive 202. Each servo drive 202 is also connected to a corresponding actuator 105 to control the actuator 105 in performing cell assembly operations. This improves the configurability and scalability of the system through the use of the I / O module 201 while reducing the possibility of bus contention and signal blocking.

[0053] In some embodiments, as Figure 4 As shown, the sensing component 102 may include a barcode scanner 203 and a pressure sensor 204 ; the barcode scanner 203 and the pressure sensor 204 are connected to the Ethernet / IP coupler 104 .

[0054] Among them, the barcode scanner 203 can be a barcode scanning gun, which can be used to scan the label of the battery cell during the loading stage of battery cell assembly, such as scanning the electronic label affixed to the battery cell, to obtain the configuration information of the battery cell, such as the batch and model of the battery cell, and upload the configuration information to the second core 40 through the Ethernet / IP coupler 104, so that the second core 40 can transmit the configuration information to the first core 30.

[0055] The pressure sensor 204 can be used to collect pressure signals and upload the collected pressure signals to the second core 40 through the Ethernet / IP coupler 104, and the first core 30 transmits the configuration information to the first core 30, so that the second core 40 transmits the configuration information to the first core 30.

[0056] In some embodiments, as Figure 4 As shown, the control system may further include a detection component for performing pressure detection; the detection component is connected to the pressure sensor 204 and the Ethernet / IP coupler 104 .

[0057] The detection component can be a comparator, pressure detector, or robot, etc., for detecting whether the pressure has reached a preset pressure value. Taking the comparator as an example, the first input of the comparator is connected to the pressure sensor 204, the second input is connected to a reference voltage converted from the preset pressure value, and the output of the comparator is connected to the Ethernet / IP coupler 104. The comparator is used to receive the sensing signal sent by the pressure sensor 204 in the form of a voltage signal, compare the sensing signal with the reference voltage, and generate a corresponding comparison signal based on the comparison result. The comparison signal is uploaded to the second core 40 via the Ethernet / IP coupler 104, and the second core 40 transmits the configuration information to the first core 30. The detection component can thus be used to determine whether the pressure in the battery cell assembly environment meets the requirements.

[0058] In some embodiments, as Figure 4 As shown, the control system may further include an MES server 50 ; the MES server 50 is communicatively connected to the first kernel 30 .

[0059] Among them, the MES server 50 is the core component of the manufacturing execution system and can be used to manage and monitor various data and tasks in the manufacturing process. It has functions including data acquisition and storage, production scheduling and planning, quality control and testing, process monitoring and analysis, etc. The MES server 50 can communicate with the first core 30 by accessing the TCP / IP port of the first core 30 to receive all data obtained by the first core 30 from the second core 40, such as sensor data, battery cell configuration information, and comparison signals obtained by the first core 30 from the second core 40, and store and analyze the received data, thereby achieving real-time tracking and monitoring of the battery cell assembly process, allowing management personnel to grasp the data information in production in real time and respond in a timely manner.

[0060] In some embodiments, the dual-system industrial computer 10 further includes a display, which is communicatively connected to the first kernel 30. Since the time-sharing operating system runs on the first kernel 30 and the time-sharing operating system can deploy a human-computer interaction interface, the human-computer interaction interface deployed by the time-sharing operating system can be displayed on the display, facilitating user operation.

[0061] In order to make the purpose, technical solutions and advantages of this application clearer, the technical solutions in this application will be described clearly and completely below. In some embodiments, Figure 4 As shown, the control system for battery cell assembly includes a dual-system industrial computer 10 equipped with a time-sharing operating system and a real-time operating system, at least one I / O module 201, at least one servo driver 202, a barcode scanner 203, a pressure sensor 204, a detection component 106, an MES server 50 and a display;

[0062] The dual-system industrial computer 10 includes a first core 30 for running a time-sharing operating system, and a second core 40 for running a real-time operating system. The first core 30 and the second core 40 are communicatively connected. The first core 30 and the second core 40 each include at least one processor core, and the number of processor cores of the second core 40 is greater than the number of processor cores of the second core 40.

[0063] Each I / O module 201 and each servo driver 202 is connected to the EtherCAT coupler 103 in daisy chain mode to form a daisy chain. Each servo driver 202 is connected to a corresponding actuator 105. At least one I / O module 201 can be connected between a servo driver 202 and the EtherCAT coupler 103, and at least one servo driver 202 can be connected between adjacent I / O modules 201.

[0064] The barcode scanner 203 and the pressure sensor 204 are connected to the Ethernet / IP coupler 104, and the detection component 106 is connected to the pressure sensor 204 and the Ethernet / IP coupler 104;

[0065] The MES server 50 is in communication with the first core 30 , and the display is in communication with the first core 30 for displaying a human-computer interaction interface deployed by the time-sharing operating system.

[0066] Taking the control system described above as executing battery cell assembly as an example, when executing a battery cell assembly task, such as battery cell placement, the human-machine interface displayed on the display can first be used to conduct communication tests and parameter tuning for devices such as the servo driver 202, barcode scanner 203, and pressure sensor 204. The barcode scanner 203 can then scan the label of the battery cell to be placed in the shell, obtaining the battery cell's configuration information and uploading it to the MES server 50. The MES server 50 then performs an inbound determination on the battery cell's configuration information to determine whether the battery cell is suitable for placement in the shell. After the MES server 50 completes the inbound determination, it generates a corresponding trigger signal, which is sent via the first core 30 to the second core 40. In response to this trigger signal, the second core 40 controls the servo driver 202 to drive the actuator 105 to perform the corresponding battery assembly operation, such as driving the actuator 105 to grab the battery cell to a predetermined station for placement in the shell. At the same time, pressure sensor 204 can detect pressure signals at predetermined workstations during the battery cell shelling process in real time. This pressure signal is then sent to detection component 106 for pressure testing. This pressure signal is then uploaded to second core 40 via Ethernet / IP coupler 104. Second core 40 then transmits this pressure signal to MES server 50 via first core 30 for storage and analysis. At the same time, detection component 106 transmits the detection signal generated after pressure testing to second core 40 via Ethernet / IP coupler 104. Second core 40 then transmits this detection signal via first core 30 to MES server 50 for storage and analysis.
