Synchronous Control Technology of Small Automatic Threading Machine Feeder Based on Machine Vision
Feeder,the key hardware of threading machine,is difficult to control.To overcome the difficulty,a machine vision based synchronization control technology for small automatic threading machine feeder is studied.The feed structure of threading machine is analyzed,the internal and external parameter models of machine vision(camera)are built,and the spatial position of the camera is calibrated.The visual image of the feeder is aquired and Roberts operator is applied to refine the visual image of the feeder.Based on PID principle,a fuzzy controller is designed,and the fuzzy output of feeder synchronization control is calculated to complete the automatic threading synchronization control of meat.The experimental data show that under different experimental conditions,the minimum value of feeder synchronization control delay obtained by the proposed technology is 2 s,and the maximum value of threading success rate is 96％.The synchronous control delay of the feeder is short,the threading success rate is high,and the control effect is better,which further improves work efficiency.
