The principle of 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:. With the help of marking liquid, the low voltage can partially ionize the metal surface, and can print any pattern or text that will never fall off on almost any conductive metal surface. It is a very economical and precise method.

Midea's marking method does not require a computer, and the purchase price is low. Second, the basic features of the laser electrocorrosion metal laser marking machine:. Formal, clear, durable, no discoloration, no falling off, high temperature resistance, not afraid of organic solvent scrubbing, no matter the size of the product, flat, curved, thin sheet can be printed, the printing is fine, the depth is 5-. 100um, easy to operate and can be completed in a few seconds without drying and curing.

Three, the application method of laser electrocorrosion metal laser marking machine:. Make the content to be printed on the stencil (screen stencil for large batches, wax paper stencil for small batches), and then place the stencil on the workpiece to be printed, and the laser marking machine will dip the output electrode of the machine Take the marking hydraulic pressure. On the top, it only takes 1-2 seconds to remove the electrode and film plate, and a beautiful logo is printed out, and it will never fall off.

Fourth, the scope of application of electro-corrosion metal laser marking machine:. 1. Hardware tools, knives, scissors, pliers, measuring tools, carbide tools. 1. When the fiber laser marking machine is not working, the marking machine and computer power should be cut off.

2. When the fiber laser marking machine is not working, cover the lens cover of the field lens to prevent dust from contaminating the optical lens. 3. If there is any failure of the fiber laser marking machine, the power supply should be cut off immediately. 4. If the equipment is used for a long time, the dust in the air will be adsorbed on the lower surface of the focusing mirror. The light ones will reduce the power of the laser and affect the marking effect, and the heavy ones will cause the optical lens to absorb.

If it is overheated, it will burst. When the marking effect is not good, you should carefully check whether the surface of the focusing lens is polluted. The workpiece of the marking fiber laser marking machine does not move, and the laser beam is deflected by the vibrating mirror, so as to realize the scanning of the graphics. The vibrating mirror is controlled by the scanning driver, and the two rotating shafts are perpendicular to each other. The vibrating mirror can realize the two-dimensional scanning of the x-y plane, and the computer is used to input the information to be marked, and then convert it into instructions to control the deflection of the vibrating mirror through the interface circuit.

At present, in marking-type fiber laser marking machines, low-inertia galvanometer-type vibrating mirrors are mostly used, such as the G325DT produced by General Scan Corporation of the United States. This kind of vibrating 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 uses a specially designed flat-field lens (f-e lens) to advance the scanning laser beam. Line focus, and make the focal plane a plane, so as to correct the image distortion caused by the scanning principle of the galvanometer. The workbench is used to place the workpiece to be marked. When marking, the focused Nd:YAG is excited.

The beam or IC automatic laser marking machine marks the workpiece by vaporization (removing material), or by instantaneous heating to change color (not removing material), because the computer can input various parameters at any time. Various information, so engraved marking has great flexibility. In the marking fiber laser marking machine, in addition to marking by galvanometer scanning, there are other structural forms, one of which is that the laser beam does not move, and the workpiece moves.

In this case, the workpiece is fixed on a z-y two-dimensional precision worktable with a ball screw structure. The worktable is driven by a stepper motor, and the computer transmits the information to be marked to the stepper. The motor drive controls the movement of the worktable. Due to the heavy weight of the worktable, the marking speed is relatively slow, but at this time, the more complicated flat-field lens is not needed, and only the knot is needed. A focusing lens with a relatively simple structure is enough. The processing quality of this focusing lens is easy to guarantee, and the cost is also low.
