The work aims to solve the problems of communication and data exchange among industrial robots, machine vision inspection system, MES system and touch control AIO machine, and realize the direct control of the bottom equipment by MES system. The main structure was designed, including photo paper assembly, logo assembly, visual inspection, packaging box assembly and other devices. The communication network and related software were designed with Delta PLC AS228P as the master controller. Modbus TCP protocol was used to realize communication with different intelligent devices through Ethernet. The assembly and packaging operation was stable, the success rate reached 99.5%, the product qualification rate reached 99.2%, and the data communication was stable and reliable, which met the requirements of industrial application. The control system can meet the needs of intelligent manufacturing and solve the problem of data communication between different devices.
