The connection mode between the CCD automatic screen printing machine and the MES system mainly relies on the compatibility of the data interface protocol and the equipment information collection structure.The MES system is typically responsible for production planning,equipment status monitoring and process flow execution.Its connection needs to be completed under the premise that the data access permission of the screen printing machine control system is open.

The common way is to achieve data interaction through industrial communication protocols such as OPC UA or Modbus TCP.Key parameters in the screen printing machine controller,such as work order numbers,image recognition positions,printing completion status,and alarm information,can be uploaded to MES through interfaces to achieve real-time updates of equipment layer data.

In addition,the CCD automatic screen printing machine should be equipped with a barcode or QR code scanning module to achieve automatic matching with work order information.After the MES system acquires the product traceability data,it can send back parameters such as image template paths and printing path files to realize full-line linkage.

In practical applications,it is also necessary to set the interface frequency and data synchronization mechanism according to the production environment to ensure the real-time and accuracy of data transmission.Through the integration of interface standardization,parameter synchronization and process traceability,the CCD automatic screen printing machine can be effectively integrated into the MES main control architecture to achieve intelligent production collaboration.
