The horizontal moving device 1 is arranged on the supporting truss 8 and is parallel to the moving direction of the steel plate; the vertical moving device 2 is arranged on the horizontal moving device 1, is vertical to the moving direction of the steel plate and realizes plane motion with the horizontal moving device 1; the laser follow-up system 3 is arranged below the vertical moving device 2 and used for marking; the control and operation system is used for controlling the action of the laser follow-up system; the speed sensor 5 is arranged below the steel plate transmission belt of the production line and used for measuring the moving speed of the steel plate; the position sensor 7 is arranged on the support truss 8 and used for sensing a steel plate in-place signal; the control and operation system is used for acquiring data of the speed sensor 5 and the position sensor 7 and controlling the horizontal moving device 1, the vertical moving device 2 and the laser follow-up system 3 to act.
Specifically, the horizontal moving device 1 and the vertical moving device 2 are long in moving distance, a gear rack mechanism can be selected, and the motors are servo motors or stepping servo motors, so that accurate control is facilitated. The horizontal moving device 1 is used for moving along with the steel plate after the laser follow-up system 3 is in place. Because the distance from the laser light outlet to the steel plate influences the marking quality, the vertical moving device 2 is used for accurately controlling the distance from the laser light outlet to the steel plate, and the marking quality is guaranteed. The light outlet of the laser random system 3 is provided with a precise distance measuring sensor 17 which performs closed-loop control with a servo motor of the vertical moving device 2, so that the requirement of the distance from the light outlet to the steel plate is met.

Meanwhile, the horizontal moving device 1 moves synchronously according to the signal of the speed sensor 5, it should be noted that, because the horizontal movement of the horizontal moving device 1 is accelerated from zero to the speed of the steel plate, and the steel plate is at a constant speed, a displacement difference is generated, and the relative movement of the sliding rod 10 and the follower base 11 can offset the displacement difference. After the follow-up, the light outlet 16 emits laser to mark. After marking, the electromagnet 15 is powered off, the vertical moving device 2 is lifted, and the horizontal moving device 2 returns to the initial position. And finishing marking at one time.
