Design of online laser marking system by vision guided based on template matching

Abstract

Abstract Industry 4.0 has put forward the requirements of improving the marking efficiency and accuracy of the laser marking industry, and manual placement has been unable to meet the production needs. In this paper, laser marking technology is combined with image recognition technology, and the automation of marking production process is realized by controlling the stepper motor to drive the conveyor belt, and accurate marking of arbitrarily placed workpiece is realized on the conveyor belt. The test results show that this marking system designed by us has high precision, and the yield of finished products reaches 99.5%, which provides a set of efficient and reliable solution for small and medium power laser marking production line to realize online positioning function.
