Laser marking machine common fault handling method
In the early stage, Foshan Fulan Laser Xiaobian shared five articles about the causes of laser marking machine related failures and their treatment methods: "Laser printers common faults and their rapid maintenance and treatment methods", "marking machine The laser intensity is reduced, the marking is not clear enough, the solution method, the "CO2 laser marking machine common failure causes and treatment measures summary", "the laser jet printer does not spray code or uneven marking reasons and solutions summary", The reason why the laser tube of the laser marking machine is not bright and its rapid processing method is different, because each laser marking machine has different models, different configurations, personnel operation and other factors, the faults are different. Many of them are new faults that are encountered in real time. Therefore, it is impossible to collect all the faults and processing methods at once. Only after processing the faults that have never been encountered before, record them and share them with everyone. Foshan Fulan Laser Xiaobian recently collected and summarized the laser marking machine common faults and treatment methods:
Fault 1: Common problems in the main control computer of the marking machine
1. Whether the graphics during processing are complicated, this must be checked;
2, the online computer does not connect to the Internet cable, it is a separate control of the laser system;
3, the operation is slow, please do not be too impatient at this time, so as not to crash;
4. Please pay attention to prevent viruses in case of system error.
Fault 2: The laser output spot of the laser marking machine has flickering phenomenon:
1. Whether the cavity adjustment is accurate;
2. Whether the diaphragm holder is fixed firmly;
3. Whether there is a problem with fixing the concentrating cavity;
4. Whether the YAG crystal is fixed tightly.
Fault three, open the key switch does not respond
1. The power supply has no power or lack of phase ----- Restore power;
2, the air switch is not closed ----- closed air switch;
3. The emergency stop switch is pressed ----- Rotate the emergency stop switch.
Fault 4, the graphic or text of the marking is distorted and deformed
1. The software has not been corrected, or the data is lost ----- parameter adjustment;
2. The galvanometer power supply is not correct ----- Adjust the switching power supply voltage, or replace it;
3. Signal interference ----- Confirm whether it is reliably grounded, and whether the signal line is in poor contact;
4. There is a problem with the control board ----- Replace the control board;
5, galvanometer failure ----- Replace the galvanometer.
Fault 5, did not reach the expected marking depth
1. The marked object is not on the focal plane ----- Adjust the focal length;
2. The F-θ lens is contaminated ----- cleaning the F-θ lens;
3. The software parameters are incorrect ----- Re-adjust the parameters;
4, the software output is abnormal ----- restart the software.
Fault six, no laser output
1. Is the software setting normal ----- Check the software settings;
2. Is the power key turned on ----- Turn on the power key;
3. Is the red light on the USB control card flashing ----- Check if the USB control card is securely connected;
4, laser power supply or laser internal fault ----- Please contact our technical staff.
Fault 7. When the software is opened, the message “Cannot find the control card, ...” pops up.
1. Control does not power up ----- Check if the key switch is turned on, and whether the switching power supply has no output;
2, the USB cable is loose ----- Check the USB cable;
3. Is the driver of the card not installed? ------ Reinstall the driver of the card;
4. USB control card is damaged ----- Replace the control card.
Fulan Laser Xiaobian reminds you warmly: Laser marking equipment is not cheap after all. If there is a malfunction, it is best not to repair it yourself, so as to avoid unnecessary loss. If any abnormality occurs during the operation, it should be closed imtely. Equipment, arrange personnel to check and maintain the equipment. Please note: To be repaired by a professional or authorized supplier of the equipment supplier, do not disassemble it yourself. You can contact the equipment manufacturer or find a professional repair in time.
