Mechanical Parts Inspection System Based on LabVIEW and Machine Vision
This paper introduces the measuring technology of dimension of mechanical parts based on machine vision,and develops hardware combinations and software functions such as external fixtures and cameras.15 valve bodies from the same batch are selected for tests including inner hole diameter,outer circle diameter,roundness,distance between the center positions of the two circles in the top view,as well as step height and overall height in the side view.The measured data are analyzed by LabVIEW and compared with the upper and lower limits of the required dimensions to determine whether the parts are qualified or not.Indicator light is provided on the front panel to indicate whether the part is qualified,in order to ensure accuracy and stability of the inspection results and improve inspection efficiency.
