Laser marking machines can be used to mark many materials, including non-flat materials. Laser marking technology is widely used in industrial production and other application fields because of its high precision and non-contact nature. It can be marked on various materials such as metal, plastic, wood, glass, and can be adapted to materials with different shapes and surfaces.
The working principle of the laser marking machine is to use a high energy laser beam to evaporate part of the material surface, thereby leaving a mark on the material. The energy density of the laser beam can be adjusted to suit the needs of different materials. For non-planar materials, laser marking machines usually use some special techniques to maintain the accurate alignment of the laser beam and the material.
One of the common techniques is the use of a three-axis dynamic autofocus system. This system can automatically adjust the laser focus based on the height and shape of the material to ensure high-quality marking in different positions and surfaces. This method ensures that the focus of the laser beam is always in place, regardless of whether the material is flat or non-flat.
Another common technique is the use of rotating devices. In this configuration, the material is placed on a rotating platform and held in place, and the laser beam is illuminated vertically on the surface of the material. The rotation of the material allows the laser beam to cover the entire surface, enabling continuous, consistent marking. This method is suitable for materials of various shapes, such as cylinders, spheres or irregular objects.
In addition, some laser marking machines are equipped with a camera system to monitor the marking process in real time and correct the laser marking position. This system can automatically recognize the shape and position of the material surface through image processing algorithms, and adjust the focus of the laser beam to the correct position. This technique can improve marking accuracy and consistency, especially for materials with complex shapes and surfaces.
In short, the laser marking machine can mark non-flat materials, and by using special technologies such as three-axis dynamic autofocus systems, rotating devices and camera systems, it can adapt to materials of various shapes and surfaces. Laser marking technology plays an important role in various industrial applications because of its high precision, fast, automated and other characteristics, bringing more convenience and benefits to the production process.
