Is the laser marking machine dangerous to the human body?

by:Leadtech Coding     2022-03-04

Laser marking machines are more and more widely used in modern industrial areas. In our daily life, we can see many electronic products, LEDs, food, medicine, packaging, machinery, etc., where the marks printed by laser marking machines can be seen everywhere. Traces, laser marking machines are so popular, many people want to know, what are the hazards of laser marking machines to the human body, and is the work of laser marking workers dangerous? Now, let's further analyze according to the principle and working process of the laser marking machine. Is the laser marking machine dangerous to the human body?

Types of laser marking machines

The common laser marking machines are mainly divided into four types, respectively Yes: UV laser marking machine, fiber laser marking machine, CO2 laser marking machine and semiconductor laser marking machine.

The working mode and working principle of laser marking machine

1. Working principle:

These four kinds of laser marking machine are mainly It is composed of XY scanning mirror, field mirror, galvanometer and computer-controlled marking software.

The working principle is that the laser beam is incident on two mirrors (scanning mirrors), and the reflection angle of the mirrors is controlled by a computer. The deflection of the beam makes the laser focus point with a certain power density move according to the required requirements on the marking material, thereby leaving a permanent mark on the surface of the material. The focused spot can be circular or rectangular.

2. Working method

The laser marking machine can engrave any vector graphics and text. This method adopts the processing method of graphics software in the computer, and has high drawing efficiency. , good graphics accuracy, no distortion and other characteristics, greatly improving the quality and speed of laser marking.

The laser marking machine can also use the dot matrix marking method, which is very suitable for the online flying laser marking machine. According to the production line of different speeds, one scanning galvanometer or two scanning galvanometers can be used. Compared with the array marking method, the galvanometer can mark more dot matrix information, which has greater advantages for marking Chinese characters.

Because of its wide range of applications, the laser marking machine can perform vector marking and dot matrix marking, the marking range is adjustable, and the response speed is fast and the marking speed is high (the number of markings per second can be Hundred characters), high marking quality, good optical path sealing performance, strong environmental adaptability and other advantages have become mainstream products, and are considered to represent the future development direction of laser marking, with broad application prospects.

3. Application range of laser marking machine

Laser marking machine is widely used in integrated circuit chips, computer accessories, industrial bearings, clocks, electronic and communication products, aerospace devices, Various automotive parts, home appliances, hardware tools, molds, wires and cables, food packaging, jewelry, tobacco and military and many other fields of graphics and text marking, as well as mass production line operations.

The harm of laser marking machine to human body

In summary, it is not difficult to see that laser marking machine will not cause mechanical harm to human body, but Laser radiation, as we all know, has certain effects on the body. In addition, the laser beam of the laser marking machine is very small, and the operator generally likes to stare at the beam of the laser marking machine, but if you stare at it for a long time, it will damage the eyes and cause a tingling sensation. It will have a certain impact on the eyes, so try not to stare at the beam when operating the laser marking machine.
