The current 3D laser marking machine adopts the front focus optical mode and uses larger X and Y axis deflection lenses. This is conducive to the transmission of a larger laser spot, which greatly improves the focusing accuracy and energy effect, and the marking surface is also larger. The 3D laser marking machine can easily solve the problem of curved surface marking. The one-time laser engraving 3D laser marking machine will not affect the energy of the surface of the processed object as the laser focal length moves up like the 2D laser marking machine, which will eventually lead to the engraving effect. not ideal.
Since the 3D laser marking machine can quickly change the laser focal length and the position of the laser beam, it is possible to mark curved surfaces that cannot be achieved by the previous 2D laser marking machine. 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.
3D laser marking machines can be divided into two types: front focus and rear focus. When the front focus mode is used, 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 to The spot is bigger, and the focused spot is smaller, and the energy density is higher; so as to meet the standard requirements of a larger area. In recent years, with the gradual expansion of market demand for 3D marking business, the current 3D laser marking technology has also attracted the attention of many industry companies. Some domestic leading laser companies have developed their own 3D laser marking machines, which are widely used in mobile phone manufacturing. , three-dimensional circuits, medical equipment, molds, 3C electronics, auto parts, electronic communications and other industries. Refined surface marking provides a professional solution for surface processing.
