In the 1990s, after decades of unremitting efforts using laser technology and energy sources such as optics and crystals, ultraviolet marking equipment was successfully developed, attracting widespread attention internationally and pioneering applications in industries such as photovoltaics, glass, and thin films. This successful development of technology, utilizing 355nm cold laser technology, solved the problems of oxidation changes and atomic active matter in marking metal surfaces.
Ultraviolet laser marking machines are generally used for ultra-fine marking and engraving. They can mark or cut non-metallic materials such as metals, plastics, and glass, and are applied in marking fields such as semiconductors, electronic appliance housings, automotive parts, glass processing, medical equipment, and engineering plastics.
Common ultraviolet laser marking machines are static devices that can only mark stationary objects. This not only wastes energy in production but also results in repetitive work for production personnel.
The current pursuit of automation and intelligent laser production line processing combines galvanometer scanning with the movement of the workpiece on the production line to form an online flying laser marking system. Online laser marking, or flying marking, is a processing method that uses lasers to process objects on the production line (i.e., the object being processed is moving relative to the laser). This processing method greatly improves processing efficiency compared to static processing and is being used by more and more users.
The online laser marking system has the following characteristics
1. The content to be printed should not be too complex, otherwise it will affect the marking speed;
2. It can be directly integrated with the production line, reducing the manpower required for loading and unloading, and allowing operators to avoid harsh production environments;
3. Automated production greatly improves efficiency;
4. Fast coding speed, increasing production output.
Overall advantages
The advantages of ultraviolet lasers are already very obvious and have been widely recognized. Online ultraviolet laser marking is undoubtedly another major technological breakthrough.
1) It has good beam quality and a smaller focused spot, enabling ultra-fine marking.
2) It has a wider range of applications.
3) The marking speed is fast and the efficiency is high.
4) The heat-affected zone is extremely small, and there will be no thermal effects or material scorching problems.
5) The machine has stable performance, small size, and low power consumption.
6) Online ultraviolet laser marking equipment, which has the characteristics of laser equipment, can realize online flying marking on the production line. It is mainly used for shallow marking of thin and fragile items such as: FPC flexible boards, PCB boards, photovoltaic solar glass, etc.
7) Based on cold processing, the effect of processing product materials will be better and better developed. When using cold laser processing, the probability of material influence is reduced to one percent, thus making full use of its processing advantages.
The performance of Guoao Technology's online laser marking system is mainly reflected in...
① It adopts imported fiber lasers and ultraviolet lasers, ensuring stable performance.
② It adopts imported high-speed galvanometers, which have high processing accuracy, fast marking speed and stable performance.
③ The software interface is user-friendly, easy to operate and learn, and has powerful editing functions.
④ It can automatically obtain information such as work order number, product batch number, material code, product name and specifications, and automatically code them.
⑤ It can automatically read QR codes and save data; if it cannot read a QR code, it will automatically record the error and trigger an alarm.
⑥ Compared to ordinary inkjet printing, it requires no consumables, is environmentally friendly and pollution-free, and requires no maintenance.

Precautions for using online UV laser marking machines
1. Conduct thorough inspections.
Before using an online laser marking machine, you must check whether its cooling fan is working properly. Only when you are sure it is working properly can you start the laser and galvanometer power supply of the marking machine, otherwise it will affect the service life of the marking machine.
2. Ensure the voltage is stable before use.
If you are unsure whether the voltage is stable, it is best to equip the marking machine with a voltage regulator to ensure it operates under stable voltage. If any power supply or other abnormalities occur during operation, do not panic. Immediately turn off the main power switch and check the cause of the fault after three minutes.
3. Ensure a good working environment
Not all working environments are conducive to the normal operation of online laser marking machines. Avoid working in enclosed spaces, as this can easily generate static electricity.
4. Clean dust regularly
Laser marking machines need to be cleaned of dust from the inside out every once in a while; otherwise, it will affect the normal operation of the laser marking machine and cause the small electronic components inside to operate inflexibly.
5. Installation and transportation
During installation, be sure to ground the entire machine and pay attention to the safety of the power connection; otherwise, abnormal power outages may cause the equipment to malfunction.
