Design of Data Converter Device for Non-destructive System
PLC is more suitable for small-scale production and simple control tasks,and it is not suitable for detecting large curved composite materials.To overcome this problem,this paper proposes to use robotic arm as the motion mecha-nism,which has the advantages of large workspace,high positioning accuracy,good flexibility and good spatial accessibili-ty.It can detect not only small planar composite materials,but also composite materials with large curved surfaces.Most of the robotic arms on the market transmit data through the TCP protocol and cannot be directly converted into pulse sig-nals.This paper proposes a data converter based on the STM32,which can receives real-time position data of the robotic arm and converts it into pulse signals to be sent to the ultrasonic detector.Through this device the mechanical part and the ultrasonic part can be connected as a whole,and the robotic arm can also be used as a moving component for non-destructive detecting system.The practical application results of the nondestructive testing laboratory show the system can effectively integrates mechanical systems and ultrasonic testing systems,expands the detecting scope of composite material.
