How to Correctly Adjust the Lens Focal Length of Fiber Laser Marking Machine？

1: Continuous Lighting Test Standard.

After marking the architectural coating material about 1 cm square or ring, after the basic filling, the laser energy is transferred to set the main parameters, the frequency of use, and then the continuous marking is checked, and a metal material laser projection part card is placed on the surface of the finished product. Barricades, such as continuing the mouse cursor, shaking the Z-axis posture, until the powerful metal business card kinetic energy laser, clear sound, high-brightness tone, most of which are the focal length of the lens, cause the detection to be several times more to find a suitable lens focal length. This method is suitable for 1064nm optical fiber line laser marking machine, semiconductor material laser marking machine, inner hole pump laser marking machine, 565nm laser marking machine, UV 532nm green laser marking machine, etc., co2 laser marking machine Able to find white paper, then draw a box in the mobile phone software for marking, keep shaking the Z axis with the light source, and make the focal plane detailed when printing paper online for free

2：This method stipulates that the machine equipment has this system configuration in the original factory. Install 1 or 2 skewed bright red light sources on the side of the galvanometer or galvanometer and use the basic principle of right triangles to find the other side of the lens focal length plan based on using a fixed right side and 2 coincident arcs right. It can quickly find the focal length of the lens by shaking it up and down in simple soil until the two bright red indicators overlap. Although this method saves time and effort, it is required that the machine manufacturer and the second machine cooperate with each other. On the other hand, if the adjustment is not very good or the center shift is performed, it is very easy to cheat and produce an incorrect lens focal length surface
