Fiber laser marking machine technology and troubleshooting

Author: Correct Pack -Laser Marking Machine Manufacturer

Fiber laser marking machine technology is used in PVC marking. Generally speaking, near-infrared lasers or far-infrared lasers (such as CO2 lasers) are used for marking on PVC materials. Far-infrared laser marking machines are the most common It is a carbon dioxide laser marking machine. The wavelength of this laser is 10.6um. This kind of marking machine can print yellow-red writing on PVC materials. Because the power of carbon dioxide laser can be very large, such as the current general power of 30W Marking machine and 50W power marking machine, so this type of marking machine can mark at a very high speed, it is very suitable for processing on the assembly line, instead of not so environmentally friendly inkjet coding. PVC material is a non-crystalline vinyl polymer material. This material has good resistance to oxidizing agents, reducing agents and strong acids. Therefore, products made of this material are used in many occasions. , electrical casings, sewer pipes, industrial accessories, etc., such a widely used product, it will be a very common event to engrave the logo on its surface. The wavelength of fiber laser is 1060nm, which can be clearly engraved on PVC material and shows black. Fiber laser is considered to be the best laser to replace semiconductor laser, and its application prospect on PVC material is also the most anticipated. , because the frequency of fiber laser marking machine can reach 80K, the light spot is very small, and the galvanometer with small light spot can reach a very high speed, and the speed of the marking line can reach or exceed the effect of CO2 laser.

However, the yellow-red color of carbon dioxide laser marking on PVC materials is often not so popular, and near-infrared lasers, such as fiber laser marking machines and semiconductor laser marking machines, have two wavelengths of UV laser marking machines. At about 1060nm, this wavelength can mark black, which is similar to the black of inkjet printers, and is the most acceptable color for customers, so this type of marking is more and more popular. Applied to PVC material. If the laser marking machine breaks down, please be sure to activate the emergency stop switch. If there is a fire, please cut off the power immediately. 1. It is forbidden to start the machine when the power supply voltage of the customer is unstable, otherwise a voltage stabilizer must be used.

2. The indoor environment will affect the life of the machine, especially the humid and dusty environment. The humid environment is easy to damage the reflector. 3. The environment where the machine is located has no pollution, no strong electricity, strong magnetism and other interference and influence. 4. It is strictly forbidden to run the laser at full power for a long time.

5. It is strictly forbidden to start the machine without grounding. All the laser marking machines produced by our company, whether it is the shell or the casing, the IC automatic laser marking machine or the control cabinet, have artificial grounding. When the machine is at the customer's place, All parts of our machine are grounded and must be completely reliable to prevent static electricity from hurting people. If there is no ground wire at the customer's site, be sure to pull a new ground wire. 6. Those who have not been trained by the manufacturer or those who have not been trained by old technology are prohibited from using the laser machine. 7. Non-professionals or personnel not authorized by the manufacturer are strictly forbidden to disassemble the machine to avoid accidents.

8. It is strictly forbidden to place any irrelevant high-reflective objects in the equipment. The reflected laser has no directionality, which is easy to cause unforeseen losses, so as to prevent the laser from being directly reflected on the human body or flammable objects, causing danger. 9. The waste materials around the machine should be removed regularly to prevent too much waste from clogging the air outlet. At the same time, care should be taken to prevent scratching the lens and rusting the lens, which may also easily cause circuit short circuit or laser discharge and ignition.
