Laser Scanner Head

Laser marking head principle

The vibrating mirror scanning marking head is mainly composed of XY scanning mirror, field mirror, vibrating mirror and computer-controlled marking software. According to the different wavelengths of the laser choose the appropriate optical components. Related options also include laser beam expanders, lasers and so on. The working principle is the laser beam is incident to the two mirrors (scanning mirror), the reflection angle of the computer-controlled mirrors, these two mirrors can be scanned along the X and Y axes, so as to achieve the deflection of the laser beam, so that a certain power density of the laser focusing point in the marking of the material according to the desired requirements of the movement, so as to leave a permanent mark on the surface of the material, the focused light spot can be circular or rectangular. In the galvanometer scanning system, vector graphics and text can be used.

This method adopts the processing of graphics by the graphics software in the computer, which has the characteristics of high graphic efficiency, good graphic accuracy, no distortion, etc., and greatly improves the quality and speed of laser marking. At the same time vibrating mirror type marking can also be used in dot matrix marking method, using this method for online marking is very suitable, according to different speeds of the production line can be used in a scanning vibrating mirror or two scanning vibrating mirror, compared with the array type marking described earlier.

Compared with the array marking mentioned above, more dot matrix information can be marked, which has a greater advantage for marking Chinese characters. Scanning galvanometer marking because of its wide range of applications, vector marking and dot-matrix marking, adjustable marking range, and has a fast response speed, high marking speed (can mark hundreds of characters per second), marking quality is higher, the optical path sealing performance is good, strong adaptability to the environment, etc. has become a mainstream product, and is considered to represent the future direction of development of the laser marking, has a broad application prospects.

Operating Modes of the Laser Scanner Head

Laser scanning heads typically have two modes of operation: point scanning and line scanning. The point scan mode is suitable for fine processing, while the line scan mode is suitable for fast cutting.

Technical features of the Laser Scanner Head
