The principle of metal laser marking machine and how to maintain it

Electrocorrosion metal laser marking machine, laser metal laser marking machine.

First, the working principle of electro-corrosion metal laser marking machine:.

The low voltage makes the metal surface partially ionized with the help of the marking liquid, which can print any pattern or text that will never fall off on almost any conductive metal surface. A very economical and refined.

The beautiful marking method requires no computer, and the purchase price is low. Second, the basic features of laser electro-corrosion metal laser marking machine:.

Formal, clear, durable, no discoloration, no shedding, high temperature resistance, not afraid of organic solvent scrubbing, no matter the size of the product, flat, curved, sheet can be printed, fine printing , the depth is 5-.

100um, easy to operate, it only takes a few seconds to complete, without drying and curing.

Third, the application method of laser electro-corrosion metal laser marking machine:.

Make the content to be printed on the stencil (screen stencil in large batches, wax paper stencils in small batches), and then place the stencil on the stencil to be printed. On the workpiece, the laser marking machine dips the output electrode of the machine into the marking hydraulic pressure.

Above, just 1-2 seconds, remove the electrode, stencil, and a beautiful logo is printed, which will never fall off.

Fourth, the application range of electro-corrosion metal laser marking machine:.

1. Hardware tools, knives, scissors, pliers, measuring cutting tools, carbide tools.

1. When the fiber laser marking machine is not working, the power of the marking machine and the computer should be cut off.

2. When the fiber laser marking machine is not working, cover the field lens lens to prevent dust from contaminating the optical lens.

3. If there is any failure of the fiber laser marking machine, the power should be cut off immediately.

4. When the equipment is used for a long time, the dust in the air will be adsorbed on the lower end surface of the focusing mirror, which will reduce the power of the laser and affect the marking effect. Optical lenses suck.

If it is overheated and burst, when the marking effect is not good, you should carefully check whether the surface of the focusing mirror is contaminated.

In the marking fiber laser marking machine, the UV laser marking machine does not move the workpiece to be processed, and the galvanometer is used to deflect the laser beam, so as to realize the scanning of the pattern, The galvanometer is controlled by the scanning driver, and the two rotating shafts are perpendicular to each other.

The galvanometer can realize two-dimensional scanning of the xy plane, the computer is used to input the information to be marked, and then convert it to control the deflection of the galvanometer through the interface circuit instruction.

At present, in the marking fiber laser marking machine, the low inertia galvanometer type galvanometer is mostly used, such as the G325DT produced by the General Scanning Company of the United States. The mirror has temperature compensation and displacement.

Compensation function, the scanning mechanical rotation angle is ±12.50, and the beam deflection angle is ±250. The focusing optical system generally adopts a specially designed flat field lens (fe lens) to Scan the laser beam in.

Focus and make the focal plane a plane, so as to correct the image distortion caused by the scanning principle of the galvanometer. The worktable is used to place the workpiece to be marked. When marking, focused Nd:YAG excitation.

The beam or IC automatic laser marking machine uses female engraving vaporization (removal of material), or instantaneous heating to change color (without removing material), to The workpiece is marked, because the computer can always input each.

A wide variety of information, so engraved marking offers great flexibility.

In the marking fiber laser marking machine, in addition to marking by galvanometer scanning, there are some other structural forms, one of which is The laser beam does not move and the workpiece is transported.

In this case, the workpiece is fixed on a zy two-dimensional precision table with a ball screw structure, the table is driven by a stepper motor, and the computer will The information to be marked is transmitted to the stepper.

The motor driver controls the movement of the worktable. Due to the large weight of the worktable, the marking speed is relatively slow, but a more complex flat field is not required at this time. lens, but simply use a junction.

A simpler focusing lens can be used, and the processing quality of this focusing lens is easy to ensure and the cost is lower.
