The working principle of laser marking machine

Laser marking machine is a marking equipment that uses laser beam to mark directly on the surface of the processed object. It can realize the precise marking of various characters, patterns and bar codes on the surface of the processed material through a laser beam to achieve customized marking requirements. The working principle of the laser strike standard machine can be roughly divided into three steps:

The first step: Operation of the laser generator

The main component of the laser marking machine is the laser generator, which is responsible for producing a laser beam for marking. Laser is a special light source which is different from natural light. It has the advantages of small scattering, good directivity and high monochromaticity. Laser generators typically use solid-state lasers, semiconductor lasers, and other technologies to accurately mark the desired marks on the surface of the workpiece.

Step 2: Focus the laser beam

The laser beam generated by the laser generator cannot be used directly, and needs to be used after a series of control and processing to achieve the marking effect. One of the main controlling factors is the focusing of the laser beam. Because different processed products require no marking using the same diameter of the laser beam, it is necessary to gather or diffuse the laser beam through the lens or collimator to form

Make a laser beam suitable for the object being processed. At the same time, it is also necessary to adjust the focusing depth of the laser beam to accurately reach the surface of the object to be machined at a certain depth on or below the surface to obtain a clear mark.

Step 3: Laser marking

After the laser beam is focused, it is guided to the processing area to achieve the desired marking effect. In this process, the laser beam is carved on the surface of the object being processed to create various patterns, text, signs, bar codes and so on. Laser marking machine can mark the surface of any material, including metal, plastic, glass, ceramics and other materials, so that it is widely used in industrial manufacturing, aerospace, electronic technology, printing and packaging and other fields.

To sum up, the working principle of the laser marking machine is to generate a laser beam through the laser generator, the laser beam passes through the lens or the collimator adjustment parts, the laser beam is focused to the appropriate depth, and then the required mark is carved on the surface of the processed object. This process is very precise and allows for high quality marking on a variety of materials. Due to the use of laser marking in the manufacturing process with the wide range of applications, more and more industries use laser marking machines to improve product quality and production efficiency.
