What are the system components of the laser marking machine?

The laser marking machine is mainly composed of the following systems.

Chassis desktop system.

Galvanometer scanning optics.

Software control system.

Laser integrated system.

The types and characteristics of the laser marking machines we come into contact with on a daily basis are different, and the application fields are naturally different.

1.Ultraviolet laser marking machine.

The main working principle of the ultraviolet laser marking machine is that the bonds between atoms or molecules are broken by the laser energy, and then become small molecules vaporized, and then all evaporated. Its main features are: by focusing on on-site performance, the influencing factors in processing are very small, and the purpose of ultra-fine marking and special material marking is realized.

2.Fiber laser marking machine.

The main working principle of the fiber laser marking machine is to output the laser through the fiber laser, and then pass through the high-speed scanning galvanometer system to finally realize the marking function. Its main features are: the conversion rate is very high, and the engraving can be completed for both metallic and non-metallic materials.

It is suitable for secret areas that require high precision, as well as for fields that require high depth and smoothness. Its main application areas: such as the marking of hardware products, the marking of glasses, clocks and watches, plastic buttons, and the marking of some medicines, food, and mobile communication equipment.

3.CO2 laser marking machine.

The main principle of the CO2 laser marking machine is to expand the laser beam, galvanometer and focus, and then control the deflection of the galvanometer to achieve marking. Its main application fields are: marking some clothing, shoes and hats, marking leather bags, marking food, cosmetics, electronic products, etc.

It can be used to mark or engrave non-metallic tea products, and there are various carving methods, such as carving, hollowing, cutting, etc.

Through the above explanation, we should find that the classification of laser marking machines is different, and the application fields are also different. Therefore, when purchasing, you must choose the right model and understand the characteristics in order to ensure that you can buy a practical laser marking machine.

We should pay attention to the use of laser marking machine:

1.When using the marking machine, remember not to press the laser head directly with your bare hands to avoid scratching the laser head.

2.It is forbidden to use sharp instruments during marking, so as not to accidentally injure the laser head and adversely affect the subsequent marking effect.

3.When removing the laser head, do not touch the film part, and remember that removing it from the edge of the laser head will help protect the entire laser head from damage.

4.When cleaning the laser head of the laser marking machine, it should be cleaned in a relatively dry and tidy environment to avoid other unclean water, dust and other pollutants from damaging the lens. This often has a significant impact on the display performance of the final device.

Clause. First, the laser marking machine is currently the most advanced laser equipment, the use is also quite extensive, such as semiconductor integrated circuit industry, food and beverage industry, jewelry handicraft industry and household appliances industry and other fields are used, laser marking machine and traditional mechanical engraving, chemical corrosion, screen printing, ink printing and other methods, has low cost, high flexibility, can be controlled by computer system, and the laser acting on the surface of the workpiece to produce a firm permanent mark is its outstanding feature.

Clause. Second, the use of laser marking machine has the following benefits:

1. Permanent: For example, the marking mark will not fade due to environmental relations (touch, acidic and reducing gases, high temperature, low temperature, etc.).

2. Anti-counterfeiting: The mark engraved by laser marking technology is not easily imitated and changed, and has strong anti-counterfeiting to a certain extent.

3. Non-contact: Laser marking is non-mechanical"Light knives"For processing, marks can be printed on any regular or irregular surface, and the workpiece will not produce internal stress after marking, ensuring the original accuracy of the workpiece. No corrosion to the working surface, none"Knives"Abrasive, non-toxic, non-polluting.

4. Wide applicability: Using laser as a processing method, it can process a variety of metal and non-metallic materials (aluminum, copper, iron, wood products, etc.).

5. High engraving accuracy: The items engraved by the laser marking machine have fine patterns and the minimum line width can be reached. The markings are clear, long-lasting and beautiful.

Laser marking meets the needs of printing large amounts of data on very small plastic parts. For example, 2D barcodes that require more precision and clarity can be printed, which is more competitive in the market than embossing or jet marking.

6. Low operating cost: The marking speed is fast and the marking is formed at one time, and the energy consumption is small, so the operating cost is low. Although the equipment investment of laser marking machine is larger than that of traditional marking equipment, in terms of operating cost, the use of laser marking machine is much lower.

For example: plastic transistor marking: the working speed of the laser marking machine is 10 seconds, if the depreciation of the equipment is calculated in 5 years, the marking degree is yuan.

If the pad printing machine is used, its comprehensive operating cost is about yuan, or even higher. Bearing surface marking: If the bearing is typed in three equal parts, a total of 18 No. 4 words, using a galvanometer marking machine, the service life of the krypton lamp is 700 hours, and the comprehensive cost of marking each bearing is yuan.

The cost of electro-etched lettering is about yuan. With an annual output of 4 million sets of bearings, only one marking, at least 1 year can reduce the cost of about 10,000 yuan.

7. High processing efficiency: the laser beam under computer control can move at high speed (speed up to 5 7 meters per second), and the marking process can be completed in a few seconds.

8. Fast development speed: due to the combination of laser technology and computer technology, users can realize laser printing output as long as they program on the computer, and can change the printing design at any time, which fundamentally replaces the traditional mold making process and provides a convenient tool for shortening the product upgrading cycle and flexible production.
