Development of Control System for the Assembly Equipments of Spacer Bar Based on PLC.

At present spacer bar cable clamp used for high voltage transmission line has been assembled manually at home, which lead to low production efficiency and unstable product quality. In order to achieve the high quality requirement of spacer bar cable clamp, a coordinated control system for spacer bar assembly equipments based on S7-200 PLC was developed. The composition of the control system was determined according to spacer bar assembly process and the hardware and the software included in the control system were designed. The new automatic control system greatly could improve the assembly efficiency and product quality, substituted for the hand labor.
