Driven by the goal of "carbon peak and carbon neutrality", the development momentum of new energy vehicles is booming, and lithium batteries, as the core components of new energy electric vehicles, are closely related to the development of the new energy vehicle industry, ushering in a broad market space, and are supported by the Internet of Things technology.
The electrode coating equipment of the lithium battery factory is to evenly mix the materials required for the positive electrode or negative electrode and other formulations, and then coat or composite on the front and back sides of the aluminum foil or copper foil, and then the liquid coating is dried or cured in the oven to form a film layer with special functions. By accessing the programmable logic controller PLC, the automatic control of feeding pump, oven, roller pressing, etc. can be realized, which has the advantages of high production efficiency, stable product quality and convenient operation mode.
By connecting the PLC of the pole piece coating equipment to the industrial Internet of Things gateway, the data is collected in real time and processed in a standardized manner, so as to realize the visual display, monitoring, alarm, control and analysis of equipment and data, so as to help the factory better control the coating quality and avoid production loss and material waste.
1. Data acquisition and transmission: The system has the function of 24-hour data acquisition and transmission, which collects the operation status and production data of the lithium battery coating machine, so that users can retrieve it at any time and manage and adjust it in time.
2. Remote monitoring: The data through edge computing will be uploaded to the cloud platform or configuration software, providing visual charts or 2D 3D process modeling, and users can quickly locate different parts of different equipment to understand the operating data and status.
3. Alarm function: When abnormal data is collected, users will also receive automatic push of alarm information on mobile phones, computers and other software, which is convenient for timely maintenance.
4. Protocol analysis and conversion: The system has a diversified protocol library, which can realize the protocol analysis and conversion of multiple devices, such as MODBUS-TCP, MODBUS-RTU, OPC-UA, etc., which can be uniformly converted into MQTT protocol and connected to the host computer cloud platform.
5. Device networking: Support 5G, 4G WiFi, LoRa and Ethernet and other ways to build a device IoT network, and you can freely choose wired or wireless mode based on the on-site environment and budget cost.
6. Data storage and management: store and manage the collected data, facilitate the query and analysis of historical data, and provide reference for equipment maintenance and management.
