In the production line with marking process, the laser marking speed can't meet the requirements of the high-speed. In order to solve this problem, the affecting factors for the speed of laser marking are analyzed. Combined with experiments, a new algorithm based on the vector trajectory optimization of the marking information is proposed. The new algorithm changes the traditional vector trajectory method which is from left to right and from top to the bottom to a new restructuring trajectory. Experiments show that the method can improve marking speed effectively.
