Galvanometer System for Laser Marking Machines|The Impact of Galvanometer Systems on Laser Marking Accuracy

As the core component of laser marking machines, galvanometer mirrors have a direct impact on the quality and stability of the marking.It analyzes the impact of galvo deflection, temperature changes, and lens contamination on marking accuracy, and provides practical calibration techniques such as galvo zeroing, setting of dynamic correction parameters, and lens maintenance, to help operators quickly resolve common problems and ensure that laser systems remain in optimal condition.

In the actual laser marking process, the galvanometer system is like the "wrist" of the equipment, and even a small deviation can greatly diminish the marking effect.Many operators have experienced problems with lines appearing blurred or patterns becoming distorted. The roots of these problems are often to be found in the galvanometer scanning system.For example, a mechanical error in the positioning of the lens can cause the laser focus to shift. If the current driving the motor is unstable, the scanning trajectory will have a sawtooth pattern. Even a 5 ° C change in temperature in the factory can cause the metal frame to expand or contract, affecting the precision of the positioning.

Calibrating the mirror requires both hardware and software.First, use the manufacturer's test pattern to do a basic test, and observe whether the crosshairs are symmetrical. This step can quickly determine whether there is a lens looseness or motor failure.If the edges of a complex image are not even, don't adjust the focus; first check the delay parameters of the mirror control card. Reducing the scan speed often has a greater effect than changing the lens.Daily maintenance is also important. The wearer is advised to use a special cleaning stick to wipe the lenses once a week. Never use ordinary paper towels, because the residue of the fibers can increase the scattering of the laser light.

Parameters must be adjusted according to the material being engraved.For example, when deep engraving on a metal surface, it is suggested that you activate the dynamic focusing function of the galvanometer system. Before processing highly reflective materials, remember to check the condition of the protective coating on the lens.Mastering these practical skills can not only boost the yield of laser marking, but also extend the life of the galvanometer and reduce the amount of time the equipment is out of service.
