Laser processing has become an important processing method in the modern processing industry. This fast, efficient, and environmentally friendly processing method is increasingly favored by users. In the field of coding and marking, the traditional two-dimensional laser marking machine has been widely used in the flat signs of various products, but with the development of the industry, when the processing requirements for three-dimensional curved surfaces appear, the traditional two-dimensional laser marking machine is difficult to meet Processing requirements. The emergence of 3D laser marking machine is a major leap in the field of laser marking. It not only restricts the surface shape of the processed object to a similar plane, but can also be extended to three-dimensional surfaces to realize efficient laser graphics of three-dimensional curved surfaces. Marking and surface microstructure manufacturing. Compared with traditional 2D laser marking machine, 3D laser marking machine has the following advantages:
First of all, a larger range and finer lighting effects.
3D marking can be divided into two types: front focus and back focus. When using the front focus mode, the main purpose is to achieve a larger marking range. Generally speaking, larger X-axis and Y-axis deflection lenses can make the incident laser spot more. Larger, smaller focal spot, higher energy density; thus meeting a wider range of needs.
Second, zooming can be implemented to achieve three-dimensional marking.
Since 3D marking can quickly change the laser focal length and laser beam position, it is possible to mark surfaces that could not be achieved in 2D in the past. After 3D marking, the cylindrical marking within the light projection range is completed at one time, which greatly improves the processing efficiency. In addition, the surface shape of many industrial products is not only a flat surface, and is powerless for two-dimensional marking. At this time, 3D marking is easier to achieve.
Third, it is more suitable for deep carving.
The traditional two-dimensional marking method has inherent defects in the deep surface carving of the object. During the engraving process, as the laser focus increases, 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 3D marking of deep carving processing, there is no such problem, which not only guarantees the effect, but also improves the efficiency.
The three-dimensional laser marking machine has increased the technical application range of laser marking processing and expanded the demand for surface marking. Some leading domestic laser companies have developed their own 3D laser marking machines and produced Kailuo laser marking machines. This machine has been widely used in precision medical equipment, auto and motorcycle parts, hardware tools, cables and other industries.
