基于TIA和PLC的全自动ABS塑料电镀控制系统设计

针对传统的ABS塑料电镀生产线自动化程度偏低、适用性差、生产成本较高和维护管理难度大等问题,设计开发了以S7-1200 PLC和博途TIA Portal为核心的ABS塑料电镀生产全自动控制系统。利用S7-1200 PLC设计主、从站控制系统,通过主站监控和管理电镀生产过程,通过从站输出控制电镀设备。在博途TIA Portal平台上设计上位机操作面板和PLC控制程序,既满足不同形状规格、牌号和用途的ABS塑料制件的电镀生产需求,又为工艺人员提供易于操作、维护和管理的应用功能。实际调试表明,所设计的系统能按照电镀工艺设定输出控制信号、反馈生产数据,实现了对电镀生产流程和工艺条件的高效监控。

Design of Automatic Control System for ABS Plastics Electroplating Line Based on TIA and PLC

Aiming at the problems of low automation,poor applicability,high cost and difficult maintenance and management in traditional ABS plastics electroplating line,an automatic control system for ABS plastics electroplating line based on S7-1200 PLC and TIA Portal has been designed. The master-slave control system is designed by S7-1200 PLC,where master station is used to monitor and manage the plating process,and the slave station outputs the control signals for plating equipments. The upper computer operation panel and PLC control program are designed with TIA Portal,which can not only meet the requirements of ABS plastics with different shapes,brands and uses,but also provide easy operation,maintenance and management for technicians. Practical debugging shows that the designed system can set output control signals and feedback production data according to the plating process,and thus realize efficient monitoring of plating production process and conditions.
