What are the four applications of precision laser processing equipment?

In recent years, the rapid development of the laser industry has made laser processing technology more and more popular in the market. Precision processing technology is an advanced manufacturing technology that meets the needs of modern high-tech and is the basis for implementing other high-tech technologies. Laser has promoted the development of precision processing technology and has played a role in the scientific development of machinery, hydraulics, electronics, semiconductors, optics, sensors, measurement technology and materials.

The traditional mechanical knife processing is replaced by invisible laser, which has high precision and fast cutting speed. It not only does not limit the cutting pattern, but also can automatically layout and save materials. The incision is smooth and the processing cost is low. It will gradually improve or replace the traditional metal cutting process equipment. Laser cutting speed is fast. The cutting seam is very narrow. The heat-affected zone is very small. The verticality of the cutting edge is very good. The cutting edge is smooth, and laser cutting materials are of various types, including carbon steel, stainless steel, alloy steel, wood, plastic, rubber, cloth, quartz, ceramics, glass, composite materials, etc.

At present, my country's traditional mechanical processing and manufacturing industry is in a critical period of technological upgrading, so what are the four applications of laser cutting machine precision processing?

Laser precision processing can be divided into four applications: precision cutting, precision welding, precision punching and surface treatment. Under the current technological development and market environment, the application of laser cutting and welding is more popular, and 3C electronics and new energy batteries are currently the most widely used fields. Laser cutting is used in sheet metal processing, aerospace, electronics, electrical appliances, subway accessories, automobiles, food machinery, textile machinery, engineering machinery, precision accessories, ships, metallurgical equipment, elevators, household appliances, craft gifts, tool processing, decoration, advertising, metal processing, kitchen utensils processing and other manufacturing and processing industries.

1. Laser precision cutting

Compared with high-power laser cutting, nanosecond lasers are usually cut precisely according to the processing object. Picosecond lasers can be concentrated in ultra-fine spatial areas, with extremely high peak power and extremely short laser pulses, which will not affect the surrounding materials in the space involved in the processing process, thereby achieving ultra-fine processing. Laser precision cutting technology has unparalleled advantages in the production processes of mobile phone screen cutting, fingerprint recognition sheets, LED invisible cutting, etc.

2. Laser Precision Welding

In the field of new energy batteries, with the promotion of new energy vehicles, the demand for power batteries continues to increase. Laser welding, as a standard welding configuration in the field of power batteries, is widely used in the fields of front pole ear welding, mid-bottom cover, top cover, sealing nail welding, rear battery connector, negative electrode sealing welding, etc. In the 3C field, laser precision welding technology is inseparable from laser precision welding technology.

3. Laser Precision Drilling

What are the applications of laser precision processing? Laser punching is widely used in the PCB industry. Compared with the traditional PCB punching process, laser can not only process PCB quickly, but also realize the drilling of small holes, micro holes and invisible holes below 2渭m that cannot be achieved by traditional equipment. On the surface of electronic products, it can also be used to drill holes in glass such as mobile phone speakers and microphones.

4. Laser Surface Treatment

Laser surface treatment can be roughly divided into the following two categories of processes. Applications that do not change the composition of the substrate include laser quenching (phase change hardening), laser cleaning, laser shock hardening, laser polarization, etc. Changing the composition of the substrate includes laser melting coating, laser electroplating, laser alloying and laser vapor deposition.

Laser cutting machines can be used for plane cutting or bevel cutting with neat and smooth edges. It can be used for high-precision cutting like metal plates and aluminum plates. At the same time, it can perform three-dimensional cutting with a robotic arm instead of an imported five-axis laser. Compared with ordinary carbon dioxide laser cutting machines, it saves more space and gas consumption, and has a high photoelectric conversion rate. It is a new type of energy-saving and environmentally friendly product, and also one of the world's leading technology products.
