A Steel Billet Crack Marking System: Design And Implementation

Abstract

In industrial billet casting, the billet's surface will inevitably crack. To mark cracks for the convenience of subsequent grinding work, a set of automatic steel billet crack marking robot is designed by our work. Based on our design, the robot combines the fluorescent magnetic powder liquid flaw detection and 3D reconstruction of steel billet to accurately mark cracks which can replace the manual marking scheme used in the current factory. In addition, due to the vibration problem in the process of billet transportation, we designed a shock-proof marker pen to ensure marking accuracy and reduce the impact of vibration on the robot. The results show that the robot can complete the automatic marking work without supervision.
