Base on the automatic assembly system controlled by PLC, this paper gives a thorough analysis on the controlling requirement of the system, the design procedure, the control scheme, the main control components and the programming ideas. In base on PLC, the system also increase the configuration software for system operation process WINCC monitoring, this paper also introduces the configuration software WINCC of control system configuration and operation method. Generally speaking, assembly refers to get the several parts of the product together with combination with accuracy and functionality in line with a predetermined size of the finished(semi) by tight with clasps,threaded connection,bonding,riveting,welding,ect. Assembly by manual processing (contact, organize, capture, motion, position, force, etc.) of each component, strictly speaking, only be described as manual assembly. The assembly which do not need to complete the assembly of the parts of the manual processing can be referred to as automated assembly. In between is semi-automatic assembly. At present,because of PLC’s powerful
