3D dynamic focusing laser marking is a laser surface concave processing method. Compared with traditional 2D laser marking, 3D marking has greatly reduced the surface flatness requirements of the processing object, and the processable effects are more colorful and more effective. Creative processing technology came into being. In the field of coding and marking, the traditional two-dimensional laser marking machine has been widely used in the plane marking of various products, but with the development of the industry, there has been a processing requirement for three-dimensional curved surfaces, (such as: mobile phone antenna, three-dimensional circuit etc.) The traditional two-dimensional laser marking machine is difficult to meet such processing requirements, so the three-dimensional 3D dynamic focusing laser marking machine came into being. The emergence of 3D dynamic focusing laser marking machine is a major leap in the field of laser marking. It is no longer limited to the surface shape of the processing object on a similar plane, but can be extended to three-dimensional solid surface to achieve high-efficiency laser marking on three-dimensional curved surface objects. Graphic marking and surface microstructure fabrication.
Compared with the traditional two-dimensional laser marking machine, the 3D dynamic focusing laser marking machine has the following advantages: Since 3D marking can quickly change the laser focal length and laser beam position, it becomes possible to mark curved surfaces that cannot be achieved in 2D before. After using 3D marking, the cylindrical marking in the light projection range can be completed at one time, which greatly improves the processing efficiency. Furthermore, the surface shape of many parts of industrial products is not just a plane, which is really powerless for 2D marking processing. At this time, 3D marking is easier to achieve.
There are inherent defects in traditional 2D marking for deep engraving on the surface of objects. As the laser focus moves up during the engraving process, the laser energy acting on the actual surface of the object will drop sharply, which seriously affects the effect and efficiency of deep engraving. For the traditional deep engraving method, the lifting platform is moved to a certain height at regular intervals during the engraving process by electric means to ensure that the laser surface is well focused. 3D marking for deep engraving processing does not have the above problems, which not only ensures the effect, but also improves the efficiency, and saves the cost of the electric lifting table at the same time.
3D marking can be divided into two types: front focus and rear focus. When using the front focus mode, the main purpose is to achieve a larger marking range. Generally, larger X and Y axis deflection lenses are used to allow the incident laser spot to be larger. Larger, and get a smaller focused spot, higher energy density; thus meet the standard requirements of a larger area. Surface blackening, such as the practice of anodized aluminum, usually uses higher frequency pulses with appropriate energy to mark under a certain defocus. The defocus distance obviously affects the energy distribution and color effect of the laser on the surface of the material. For general 2D marking users, even if advanced features such as curved surface marking are not required, it is very meaningful for 3D marking machines to perform plane processing with multi-grayscale and multi-color effects.
