| Abstract: | The sensitivity of contactless ultrasonic sensor is improved from 3.3% to26% through acoustic, electric matching technique. Along {wo crest lines auto seam tra-cking is firstly realized with contactless ultrasonic sensing. The focused acoustic lens isdesigned with the best of care, the diameter with 0.5mm of sonic beam is achieved,Through software and hardware technique the horizontal precision of seam tracking withultrasonic sensing is to 0.5mm and the vertical precision of that is to 0.2mm. |
