Two, carbon dioxide laser marking machine working principle
Laser marking is a laser beam on the surface of a variety of different substances with a permanent mark. Marking effect is through the surface layer of material evaporation to reveal the deep material, or through the light energy caused by the surface layer of material chemical and physical changes and "carve" traces, or through the light energy to burn off part of the material, showing the required etching pattern, text.
At present, the recognized principle is two kinds:
"Thermal processing" has a high energy density of the laser beam (it is a concentrated energy flow), irradiated on the surface of the material to be processed, the material surface absorbs laser energy, in the irradiated area to produce thermal excitation process, so that the material surface (or coating) temperature rises, resulting in metamorphosis, melting, melting. rises, producing phenomena such as metamorphosis, melting, ablation and evaporation.
"Cold processing" has a high loading energy of (ultraviolet) photons, which can interrupt the chemical bonding within the material (especially organic materials) or the surrounding medium, to the point where the material undergoes a non-thermal process of destruction. This kind of cold processing has a special significance in laser marking, because it is not thermal ablation, but cold stripping that breaks chemical bonds without the side effect of "thermal damage", and thus does not produce heating or thermal deformation of the inner layer of the processed surface and the surrounding area. For example, in the electronics industry, excimer lasers are used to deposit thin films of chemicals on substrate materials and to create narrow slots in semiconductor substrates.
Three, carbon dioxide laser marking machine use process
Check the water line, the circuit is correct before starting.
Power on the order of: ① Turn on the incoming power, open the key switch. At this time the machine pumping and refrigeration system is energized, the ammeter shows the value of 7A or so;
② wait 5 to 10 seconds, press the trigger button on the external control panel, the ammeter shows the value of zero, 3 to 5 seconds after the krypton lamp ignited, the ammeter shows the value of 7A. (Refer to the laser power supply operating instructions);
③ open the vibrating mirror power supply;
④ open the computer, call the desired playing Open the computer, call out the required marking file;
⑤Adjust the laser power supply to the working current (10-18A), you can start marking;
After marking, turn off the power of each component in the reverse of the above order:
①Set the laser power supply to the minimum working current (7A or so);
②Shut down the computer;
③Shut down the vibrating mirror power supply;
3 power supply;
④Press the stop button;
⑤Turn off the key switch;
⑥Disconnect the incoming power supply.
Four, the operation of the carbon dioxide laser marking machine precautions
(1) CO2 laser marking machine in the adjustment of the use if found due to moisture or other reasons for discharge, you should immediately shut down the machine, maintenance.
(2) CO2 laser marking machine in the low current can work continuously for 4 hours, high current can be appropriate to shorten the use of time.
(3) The casing should be grounded, and the power cord is a single-phase three-wire.
(4) When the light guide joint arm is not in use, please place it in the drying box to prevent the lens from getting moldy.
(5) Maintenance should first cut off the power supply and high-voltage discharge to ensure safety.
