Marking or etching on the film is to form patterns, lines, characters, bar codes and other information by irradiating the film surface with high-energy laser beam. Is the laser marking machine and the etching machine the same equipment?
The principle of the laser marking machine is the same as that of the laser etching machine. It can be understood that the laser etching machine is an upgraded version of the laser marking machine. These two devices can choose different lasers according to the characteristics of the processing materials. What is the difference between these two devices?
The laser etching machine for conductive metal film etching is developed for touch screen, optoelectronics, military, scientific research and other fields. Its function is to remove the conductive metal on the surface of thin film materials and form conductive lines, such as ITO laser etching and silver award laser etching.

According to the present invention, the surface marking pattern, characters, two-dimensional code and other information of the thin film material are processed, and the material surface with a thickness of several microns is peeled into a pattern different from the color of the substrate, thereby forming a chemical or physical reaction. Such as two-dimensional code marking.

Based on the different laser marking machines, the working principle of the laser etching machine is also different. Its working principle mainly includes optical path, software, visual recognition, processing difference caused by linear motor, dust extraction and adsorption functions.
Due to the different optical path structures in the laser etching machine, the optical path part is more complex, which needs to be optimized by means such as the reflective lens. However, there are differences in the direct light output mode between the vibrating lens and the laser marking machine.
The software part of the laser etching machine is a specially developed system, which integrates vision, motor, touch control and other functions, mainly for the processing of circuit graphics. The laser is a kind of marking software. It has only processing control function and no other control function. Of course, it also has additional functions, which requires special customization and secondary development.
The camera positioning function is specially added to the visual recognition of some laser etching machines to ensure the processing accuracy. And the marking machine usually does not have this function. Of course, with the continuous improvement of customer demand, there are also some laser marking equipment in the market.
In order to improve the processing width and speed on the premise of ensuring the processing accuracy, the linear motor is used, but the laser marking machine does not have this function. Similarly, with the improvement of processing requirements in the market, laiser laser has also developed a large format laser marking machine controlled by a screw rod, with an effective processing width of 600 * 600mm.
Other components include the laser etching machine to ensure the flatness during the etching process and the dust after evaporation. Moreover, the marking machine does not have this function. At most, a set of marking machine is added outside. The system also uses a laser etching machine as a marble stable platform to ensure the stability of the whole device when the linear motor is running.
