Laser cutting system

Abstract

The invention relates to the technical field of laser cutting and discloses a laser cutting system. The laser cutting system comprises a laser light source assembly, an optical assembly, a three-dimensional motion assembly and a computer, wherein the three-dimensional motion assembly comprises an x-y-axis moving platform and a z-axis moving platform, the x-y-axis moving platform drives materials to be machined to move in the x direction and in the y direction, and the z-axis moving platform drives the optical assembly to move in the z direction. The laser light source assembly emits machining laser beams, second laser beams and third laser beams are formed by the machining laser beams under the action of the optical assembly and are focused on the materials to be machined to machine the materials. A first zone without laser beams is formed between the second machining beams and the third machining beams. The computer is connected with the laser light source assembly, the optical assembly, the x-y-axis moving platform and the z-axis moving platform. According to the laser cutting system, images of the surfaces of the materials to be machined can be observed and detected, and focuses of the machining light beams can be automatically adjusted.

Problems solved by technology

However, the use of the capacitor height controller can only work when cutting metal. When the capacitor height controller is cutting non-metal, because the capacitance formed is very small, it is difficult to detect and control, so the capacitor height controller cannot be used for non-metallic materials.
