Abstract: According to the deficiency of the traditional printing screen printing unit such as poor anti-interference ability, weak communication networking function, low position control accuracy, the big pollution of net frame up and so on, this paper put forward a kind of electrical control improved scheme aiming at above deficiency. At the same time we use the Panasonic FP-X PLC as the center controller of each printing unit，Each printing unit forming monitored control system though PC-LINK communication networks, and the touch screen as a display and control unit, dynamically monitoring the production process. The printing unit scraper system and network frame lifting system technology is improved by using new permanent magnet synchronous servo driving strategy. Though the renovation to a number of enterprises equipment, results show that system has high control precision, fast speed, full functions, high degree of automation, and the efficiency of production and management of enterprises is improved.
