The research of wire grinding machine and wire stripping machine control system based on PLC

摘要

This paper introduces PLC control technology and discusses its characteristics with relay control circuit, computer, SCM control technology????then it talks about the PLC control system design methods. To use the method in reality, the paper introduces wire grinding machine and wire stripping machine. In the wire grinding machine, the module is single and easier, with principle of how it works, PLC obtains the status of sensors, data such as the diameter value to control the operation of the corresponding parts to form a closed loop between PLC control system, the motor and wire diameter grinding detectors to grind the wire into segments with different diameters. Finally, the paper completes the PLCbased control system design of stripping machine. The system requires nine different ways to meet the processing requirements, the papers designs multifunctional modules to realize the requirements. Both of the two PLC systems operates very well in reality.
