[0002] With the continuous development and popularization of intelligent manufacturing and industrial internet technologies, the demand for intelligent equipment is becoming increasingly important. Building a platform-based, integrated hardware and software solution for intelligent equipment control systems can quickly address these needs and enhance the intelligent capabilities of industrial products. Important real-time data generated by production equipment during the production process is typically collected by industrial software (MES - Manufacturing Execution System). Through the installation and deployment of an MES system, production data can be collected and transmitted in real time, enabling targeted adjustments and effective production control.

[0003] During the deployment of MES data acquisition hardware, for some production processes, especially the printing and testing process in battery production, there are approximately 400 test points across ten production lines. The large number and wide range of these test points, with each production line test point connected to the MES server, would make the transmission lines extremely complex and result in high deployment and management costs. Summary of the Invention

[0004] In view of this, the present invention provides a data acquisition device for a battery printing production line, which aims to solve the problem of high cost of data acquisition hardware deployment and management in the existing MES technology.

[0025] In the following description, specific details such as particular system architectures and techniques are set forth for illustrative purposes and not for limitation, in order to provide a thorough understanding of the embodiments of the invention. However, those skilled in the art will understand that the invention can be implemented in other embodiments without these specific details. In other instances, detailed descriptions of well-known systems, apparatuses, circuits, and methods are omitted so as not to obscure the description of the invention with unnecessary detail.

[0026] Explanation of relevant terms in this invention:

[0027] TOPCon cells, or Tunnel Oxide Passivated Contact cells, are a novel passivation contact technology. This technology uses an ultrathin oxide layer and doped silicon film for passivation on the cell surface. Simultaneously, the ultrathin silicon oxide reduces surface states, maintaining a low tunneling resistance, while the doped silicon film provides field-induced passivation and selective carrier permeability, forming a good passivation contact with the silicon substrate. TOPCon cells represent the current trend in high-efficiency battery development.

[0028] MES: Manufacturing Execution System, is the execution layer (bridging the gap) between the planning layer and the field automation system. It is primarily responsible for shop floor production management and scheduling, implementing management functions such as production scheduling, product tracking, quality control, equipment management, fault analysis, and network reporting. Using a unified database and network connectivity, it can simultaneously provide shop floor management information services to departments such as production, quality inspection, process, and logistics.

[0029] SPC: Statistical Process Control. It uses statistical methods to control each stage of a process, thereby improving and ensuring quality. SPC emphasizes prevention throughout the entire process.

[0030] OPC: The OPC standard is a set of specifications jointly developed by industry suppliers, end users, and software developers. These specifications define the interfaces between clients and servers, as well as between servers. For example, accessing real-time data, monitoring alarms and events, accessing historical data, and other applications all require the coordination of the OPC standard.

[0031] Figure 1 This is a schematic diagram of the data acquisition device for a battery printing production line provided in an embodiment of the present invention. Figure 1 As shown, in some embodiments, the battery printing production line data acquisition device includes: multiple local area network (LAN) acquisition ports 11, a gateway 12, and an MES server 13; each battery production device is connected to at least one LAN acquisition port 11, and each LAN acquisition port 11 is used to collect production data of the connected production device; the multiple LAN acquisition ports 11 are connected to the gateway 12; the gateway 12 is used to acquire the production data collected by each LAN acquisition port 11 and perform consistency processing on all acquired production data; the gateway 12 is connected to the MES server 13; the gateway 12 is also used to report the consistency-processed production data to the MES server 13.

[0032] In this embodiment of the invention, the battery printing process is a single-line, dual-track process involving multiple equipment such as a feeding machine, printing machine (4 times), oven (3 times), sintering, photoinjection, unloading machine, and integrated machine. This results in a large number of test points, making data acquisition difficult. Connecting all points to the MES server via network cables would be extremely cumbersome and costly. This solution uses various hardware sensors, barcode scanners, PLCs, industrial computers, and other data acquisition devices to collect data from these equipment and upload it uniformly to the corresponding local area network (LAN) acquisition port 11. Each LAN acquisition port 11 then transmits the data to the gateway 12, where it is processed into standardized production data and finally reported to the MES server. This invention achieves millisecond-level data acquisition, ensuring that all production information, process information, and alarm information are grasped immediately, making the entire process transparent, digital, and comprehensive. The network layout is simple and highly stable. The gateway can be an industrial router, computer, etc., and is not limited here.

[0033] In this embodiment of the invention, all production data is collected by a gateway 12, and then processed into production data of the same format by the gateway 12. Finally, the data is directly transmitted from the gateway 12 to the MES server 13, thereby effectively reducing the large number of complex transmission lines generated by connecting the production line test points to the MES server 13, effectively reducing the complexity of the transmission lines and reducing the cost of the device.

[0034] In some embodiments, the type of local area network acquisition port 11 includes, but is not limited to, at least one of the following: printing energy consumption acquisition port, printing automation information acquisition port, printing host information acquisition port, sintering furnace information acquisition port, safety monitoring information acquisition port, and test analysis information acquisition port.

[0035] In this embodiment of the invention, printing energy consumption specifically includes energy consumption data such as water, electricity, gas, and paste. Printing automation information, printing main unit information, and sintering furnace information specifically include machine status, process parameters, station data (traceability query), and production capacity uploaded by the automated equipment, main unit, and sintering furnace. Safety monitoring information may include alarms for abnormal process parameters and equipment status. Test analysis information may include yield rate, electrical performance display, and efficiency level distribution information from test sorting.

[0036] In some embodiments, gateway 12 includes multiple gateway devices; each gateway device is connected to a type of local area network acquisition port 11; and all multiple gateway devices are connected to MES server 13.

[0037] In this embodiment of the invention, there are approximately 400 test points across ten production lines. While a single gateway can simultaneously collect data from all 400 test points, this method has a low fault tolerance and places high performance requirements on the gateway. Therefore, gateway 12 can be a single gateway device or a combination of multiple gateway devices; this is not limited here. The 400 test points can be divided according to the data type being collected or the data collection volume per test point, with one gateway device configured for each group of test points. This reduces the operational requirements of each gateway device while improving the data acquisition fault tolerance.

[0038] In some embodiments, multiple gateway devices form at least one gateway device group, each gateway device group includes at least two gateway devices, and the gateway devices in each gateway device group are interconnected.

[0039] In this embodiment of the invention, multiple gateway devices can be grouped together, and the gateways in each group are interconnected. When a fault occurs in itself, the collected data is transferred to other devices in the group for processing. That is, each gateway in the group serves as a backup gateway for the other.

[0040] In some embodiments, each gateway device is further configured to instruct the connected LAN acquisition port 11 to collect production data according to the acquisition frequency after receiving the acquisition frequency from the user input / MES.

[0041] In this embodiment of the invention, each gateway can be individually configured to set the acquisition frequency of the local area network acquisition port 11 it is connected to.

[0042] In some embodiments, multiple local area network acquisition ports 11 are connected to the gateway 12 via a serial-to-RJ45 module converter.

[0043] In this embodiment of the invention, a serial port to RJ45 module converter and an OPC protocol gateway server are added, enabling interconnection between devices such as RFID information, automation PLC, process equipment PLC, and equipment industrial control computer using TCP communication, realizing internal data processing. The gateway server reads PLC data through OPC, converts the data read by OPC into XML format (plain text format) for processing, and achieves consistency with other data in form.

[0044] In some embodiments, gateway 12 is connected to MES server 13 via a network cable.

[0045] Figure 2 This is a diagram of the data entry interface of the data entry terminal provided in an embodiment of the present invention. Figure 2 As shown, in some embodiments, the device further includes a data entry terminal; the data entry terminal is connected to the gateway 12; the data entry terminal is used to send the production data entered by the user to the gateway 12.

[0046] In this embodiment of the invention, production personnel can input data that is difficult for equipment to capture, such as fragments, defects, target capacity, SPC information, and PM time, onto a data entry terminal. Figure 2 Data is entered using the table format shown. This reduces the use of paper documents, lowers the error rate, and makes querying and statistics more convenient.

[0047] In some embodiments, the device further includes a camera device; the camera device is connected to the gateway 12; the MES server 13 is used to send a verification command to the gateway 12 when abnormal production information is detected; the gateway 12 is used to turn on the camera device after receiving the verification command and send the image captured by the camera device to the MES server 13.

[0048] In this embodiment of the invention, when certain production data is abnormal, in order to distinguish whether it is a production problem or a data acquisition / entry error, corresponding camera devices can be set up at various locations in the process. By taking pictures and analyzing the process corresponding to the abnormal data, erroneous production adjustments caused by data acquisition / entry errors can be avoided. However, the image analysis process is generally quite complex; to reduce costs, image analysis is only performed on the process corresponding to the abnormal data.

[0049] In some embodiments, the communication protocol between the multiple local area network acquisition ports 11 and the gateway 12 is the OPC protocol.

[0050] In summary, the beneficial effects of this invention are as follows: It achieves automated connection to the main equipment, bypassing switches and using direct field connection. Data is processed internally, with numerous points automatically reporting and outputting data uniformly. Finally, the data is uploaded to the MES server via a single network cable. Data that other devices cannot directly capture is manually entered into the lineside data acquisition software, and finally, the MES server collects and summarizes the data. This simplifies complex network cabling, reduces production costs, and facilitates future maintenance.
