co2 laser marking machine engraving machine maintenance manual. One, the laser head does not emit light. 1. Press the test button on the operation panel to check the status of the ammeter:.
①No current: Check whether the laser power supply is connected, whether the high-voltage wire is loose or disconnected, and whether the signal wire is loose. ②There is current: Check whether the lens is broken and whether the optical path is seriously shifted. 2. Check whether the water circulation system is normal:.
① No water flow: Check whether the water pump is damaged or not powered on. ②Water connection: Check whether the water inlet and outlet are reversed or the water pipe is broken. 3. Capable of burst shooting, self-checking, and no light for sending data (check whether the computer settings are correct).
Second, the laser engraving has different depths or not deep enough. 1. Check whether the water flow in the water circulation system is smooth (the water pipe is bent or the water pipe is broken). 2. Check whether the focal length is normal (re-calibrate).
3. Check whether the optical path is normal (re-calibrate). 4. Check whether the paper on the plate is too thick and whether there is too much water (re-correct). 5. Check whether the beam is parallel (adjust the belts on both sides).
6. Check whether the lens is broken (replace). 7. Check whether the lens or the emitting end of the laser tube is polluted (re-clean). 8. Check whether the water temperature is higher than 30°C (replace the circulating water).
9. Check whether the laser head or focusing lens is loose (tightened). 10. The laser current and light intensity must reach 8mA. 11. The laser tube is aging (replacement).
12. Lifting platform. Three, the reset is abnormal. 1. The laser marking machine checks whether the sensor is dusty, poorly connected or damaged (wipe off the dust on the sensor or replace it).
2. Check whether the flexible conductive tape data cable is in poor contact or damaged (trimming the data cable and re-plugging or replacing the data cable). 3. Check whether the contact of the ground wire is reliable or whether the high-voltage wire is damaged (re-ground or replace the high-voltage wire). 4. The motor wires are in poor contact.
Fourth, omission of engraving. 1. The initialization is incorrect, and the data has been sent (corrected). 2. The order of operations is reversed (re-output).
3. Static interference (check if the ground wire is off). 4. Computer problems (replace the host). Category of laser marking machines.
Lamp pumped YAG laser marking machine. YAG laser is a solid-state laser with a wavelength of 1.064um in the infrared frequency band. It uses a krypton lamp as the energy source (excitation source). ND: YAG (Nd: YAG laser, Nd (neodymium) is a rare earth element, YAG stands for yttrium aluminum pomegranate Stone, whose crystal structure is similar to ruby) as the medium for generating laser light, the excitation source emits incident light of a specific wavelength, which promotes the population inversion of the working substance, releases the laser light through the energy level transition, amplifies the laser energy and shapes and focuses it to form a laser The laser beam used. Diode pumped YAG laser marking machine.
The semiconductor pump laser marking machine uses a semiconductor laser diode (measurement surface or end surface) with a wavelength of 0.808um to pump the Nd:YAG medium, so that the medium produces a large number of inversion particles and forms a wavelength of 1.0 UV laser marking under the action of the Q switch. The 64um giant pulse laser output of the machine has high electro-optical conversion efficiency. Compared with the lamp-pumped YAG marking machine, the semiconductor-pumped laser marking machine has better stability, power saving, no need to change the lamp, etc., the price Relatively high. Fiber laser marking machine. The marking machine that uses fiber laser to produce laser has good beam quality and high electro-optic conversion efficiency.
CO2 laser marking machine. The CO2 laser is a gas laser with a wavelength of 10.64um in the far-infrared frequency band. CO2 gas is used to fill the discharge tube as the medium for generating laser light. When a high voltage is applied to the electrode, a glow discharge is generated in the discharge tube to release gas molecules. The laser is emitted, and the laser energy is amplified to form a laser beam for material processing. The process of using the laser marking machine.
Check the water circuit, and start the machine after the circuit is correct. The start sequence is: . ① Connect the incoming power supply and turn on the key switch. At this time, the machine is ventilated and the refrigeration system is powered on. The ammeter shows a value of about 7A. ②Wait for 5-10 seconds, press the trigger button on the external control panel, the ammeter will display a value of zero, after 3-5 seconds, the krypton lamp will be ignited, and the ammeter will display a value of 7A, (refer to the operation manual of the laser power supply).
③ Turn on the power of the galvanometer. ④ Turn on the computer and call up the required marking files. ⑤ Adjust the laser power supply to the working current (10-18A), and then start marking.
After the marking is finished, turn off the power supply of each component reversely according to the above sequence:. ① Adjust the working current of the laser power supply to the minimum (about 7A for IC automatic laser marking machine). ② Shut down the computer.
③Turn off the power of the galvanometer. ④Press the stop button. ⑤ Turn off the key switch.
⑥ Disconnect the incoming power supply. Common problems and solutions of laser marking machines. Fault 1: The laser intensity drops, and the marking is not clear enough.
Marking machine solution:. ① Whether the laser resonant cavity changes, fine-tune the resonant cavity lens to make the output spot the best. ②The acousto-optic crystal is offset or the output energy of the acousto-optic power supply is low, adjust the position of the acousto-optic crystal or increase the working current of the acousto-optic power supply.
③The laser entering the galvanometer is off-center: adjust the laser. ④ If the current is adjusted to about 20A, the photosensitive intensity is still not enough: the krypton lamp is aging, replace it with a new lamp. Marking machine failure 2: The krypton lamp cannot be triggered (refer to the NTP power supply manual).
Marking machine solution:. ① Check all power cables. ②The high-voltage krypton lamp is aging, replace the krypton lamp.
③Precautions for operating the laser marking machine. ① It is strictly forbidden to start the laser power supply and Q-switching power supply when there is no water or the water circulation is abnormal. ②The Q power supply is not allowed to work without load (that is, the output terminal of the Q-modulated power supply is suspended).
③If there is an abnormal phenomenon, first turn off the vibrating mirror switch and the key switch, and then check. ④ It is not allowed to start other components before the krypton lamp is ignited to prevent high voltage from entering and damaging the components. ⑤ Note that the output terminal (anode) of the laser power supply is suspended in the air to prevent ignition and breakdown with other electrical appliances.
⑥Keep the internal circulating water clean, clean the water tank regularly and replace it with deionized water or pure water.
