Common problems of fiber laser marking machine

Handling of common problems of fiber laser marking machine

The technology of fiber laser marking machine is applied in PVC marking. Generally speaking, near-infrared laser or far-infrared laser is currently used for marking on PVC materials. Laser (such as CO2 laser), the most common far-infrared laser marking machine is a carbon dioxide laser marking machine. The wavelength of this laser is 10.6um. This marking machine can make yellow-red writing on PVC materials. The power of the laser can be very large, such as the current general 30W power marking machine and 50W power marking machine, so this type of marking machine can mark at a very high speed, which is very suitable for the production line. Processing, instead of less environmentally friendly ink Leadtech Coding.

PVC material is a non-crystalline vinyl polymer material, which has good resistance to oxidizing agents, reducing agents and strong acids, so it is currently used in many occasions. For products made of this material, electrical enclosures, sewer pipes, industrial accessories, etc., such a widely used product, it will be a very common event to engrave a logo on its surface.

The wavelength of the fiber laser is 1060nm, which can be clearly engraved on the PVC material and show black color. The fiber laser is considered to be the best alternative to the semiconductor laser. Laser, its application prospect on PVC materials is also the most anticipated. Because the frequency of fiber laser marking machine can reach 80K, the spot is very small, and the galvanometer with small spot can achieve very high speed. In the marking line The speed can reach or exceed the effect of CO2 laser.

However, the yellow-red marking of PVC materials by carbon dioxide lasers is often not so popular, and near-infrared lasers such as fiber laser marking machines and semiconductor laser marking The wavelengths of the two types of UV laser marking machines are around 1060nm, but this wavelength can mark black, which is similar to the black of ink jet printers, and is a kind of black that Z can accept for customers. Color, so this type of marking is more and more applied to PVC materials.

If the laser marking machine fails, please be sure to activate the emergency stop switch, and if there is a fire, please cut off the power immediately.

1. It is forbidden to start the machine when the power supply voltage is unstable at the customer's place, otherwise a voltage stabilizer must be used.

2. The indoor environment will have an impact on the life of the machine, especially in humid and dusty environments, which are easy to make the reflector.

3. The environment where the machine is located has no pollution, no interference and influence from strong electricity and strong magnetism.

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, IC automatic laser marking machine or control Cabinets are grounded artificially. When the machine is at the customer's place, all parts of our machine must be grounded reliably to prevent static electricity from hurting people. If there is no ground wire at the customer's place, be sure to pull a ground wire again.

6. It is forbidden to use the laser machine without the factory training personnel or the personnel who have not been brought by the old technology.

7. Non-professionals or personnel not authorized by the manufacturer are strictly prohibited from disassembling the machine without authorization to avoid accidents.

8. It is strictly forbidden to place any irrelevant high-reflection objects in the equipment. The reflected laser has no directionality, and it is easy to cause unforeseen losses to prevent the laser from being directly reflected to the human body or flammable materials, causing a hazard.

9. It is necessary to regularly remove the waste around the machine to prevent too much waste from blocking the air outlet. At the same time, care should be taken to prevent the lens from being scratched, the sheet is rusted, and it is also easy to cause Short circuit or laser discharge sparks.
