Traditional process changed by laser technology
Due to the immature production technology, laser technology did not have many practical uses at the beginning. Although there are applications such as cutting and beam weapons, it is subject to high manufacturing costs and complicated climatic conditions. Over the past century, engineers and experts in various fields have been working hard to improve innovative technologies and applications. Laser cutting, welding, fiber laser marking and other technologies have been widely used in all aspects of industrial production and social life, and have replaced many traditional manufacturing processes.
Mobile phone (3C) manufacturing
Mobile phone (3C) consumer electronics products are being upgraded in the direction of high integration and high precision. The internal components of their products are getting smaller and smaller, and the degree of electronic integration is getting higher and higher. Therefore, screens, circuit boards, back covers, and internal structural parts (appearance, deformation, pullout force) require increasingly higher cutting, welding, and marking technologies.
At the same time, with the problems of short product cycles and large shipments, traditional printing, stamping, CNC and other processes have been unable to meet the high-quality processing needs, or can not effectively control production costs. After a long period of development, laser technology has been able to easily implement processes that cannot be achieved by conventional methods, and has become the unanimous choice of high-end users such as Apple and Lansi Technology.
In developed industrial countries such as Europe and the United States, currently 50% to 70% of auto parts are processed by laser (laser body welding of body panels, welding of body-in-white top cover, laser three-dimensional cutting of cover parts, laser marking and cladding of parts) It is completed with high speed, high precision and good quality.
With the new energy policy and the trend of continuously launching new products in the market, the lightweight and more efficient production technology of automobiles is crucial to the development of automobile production enterprises.
New energy battery welding
Power batteries are the core components of new energy vehicles, which directly determine the performance of the entire vehicle. The traditional processing method of the battery shell is completed by ordinary welding or deep throat stamping and drawing, but the safety, service life and comprehensive cost cannot always meet the market requirements. The comparison found that the advantages of laser welding are low welding material loss, small deformation of the workpiece to be welded, stable equipment performance and easy operation, and high welding quality and automation.
It can be said that the advantages of the laser welding process are unmatched by other welding methods. As the new energy vehicle industry moves toward in-depth development, higher requirements are placed on the assembly and welding accuracy and quality of the supporting batteries. Large-scale use of laser welding technology is also imperative.
Sheet metal processing
Before the outbreak of the laser market, the processing of various types of metal sheet parts could not avoid the CNC turret punching process. Through a simple mold combination, it can automatically complete a variety of complex hole patterns and shallow stretch forming processes at one time. However, when fiber laser technology becomes mainstream in the market, laser processing shows great advantages.
Fiber laser processing is not only high-precision and high-efficiency, but also can process both thin and thick plates, various complex graphics and curved surfaces, without the need for mold opening, and it is easier to achieve automation. Therefore, laser processing on the market has begun to replace some CNC turret punching and shearing machines.
When "manufacturing" meets "environmental protection", how to find a cleaner and non-destructive cleaning method has become a problem that bosses have to consider. Compared with traditional cleaning methods such as mechanical friction cleaning, chemical corrosion cleaning, strong liquid solid impact cleaning, and high-frequency ultrasonic cleaning, laser cleaning has the advantages of safety, high efficiency, and no pollution.
At present, laser cleaning is mainly used in industrial fields such as molds, weapons and equipment, aircraft old paint, electronics industry, stone carving, etc. With the continuous improvement of technology and the mass production of equipment, laser cleaning technology will definitely play an important role in the field of industrial cleaning.
