The laser marking machine is used to mark various symbols, characters, patterns, etc. with extremely fine spots, and the spot size can be in the order of microns. It has a deeper meaning for micro-processing or anti-counterfeiting.

The focused ultra-fine laser is like a sharp blade, which can remove the material on the surface of the object point by point. The biggest advantage is that the marking process is non-contact processing, which will not cause negative scratches and friction, and will not cause extrusion or crushing. Therefore, the item to be processed will not be damaged. After the laser beam is zoomed again, the light spot becomes smaller, the thermal effect area is small, and the processing is accurate, so some processes that cannot be completed by conventional methods can be completed.

Laser processing can realize any form of plate cutting with the help of modern CAD/CAM software. Using laser processing not only has fast processing speed, high efficiency and low cost, but also avoids mold replacement and shortens the production preparation time period. It is easy to realize continuous processing, and the laser beam transposition time is short, which improves the production efficiency. Various workpieces can be installed alternately. When a workpiece is processed, the completed parts can be removed and the workpiece to be processed can be installed to realize parallel processing, reduce installation time and increase laser processing time. Laser cutting has become the technological development direction of modern metal processing due to its high speed, high precision, high quality, energy saving and environmental protection. In laser processing applications, laser cutting accounts for 32% of the market share. Compared with other cutting methods, the biggest difference between laser cutting is that it has the characteristics of high speed, high precision and high adaptability. At the same time, it also has the advantages of small kerf, small heat-affected zone, good cutting surface quality, no noise during cutting, good verticality of the kerf edge, smooth cutting edge, and easy automatic control of the cutting process. When laser cutting plates, no molds are required, and it can replace some punching methods that require the use of complex and large molds, which can greatly shorten the production cycle and reduce costs.

Sheet metal processing is a key technology that sheet metal technicians need to master, and it is also an important process for forming sheet metal products. It includes not only traditional methods and processes such as cutting, blanking, bending and forming, but also various cold stamping die structures and process parameters, various equipment working principles and operating methods, as well as new stamping technologies and new processes. . The sheet metal processing parts of agricultural machinery products generally use 4-6mm steel plates. There are many types of sheet metal parts, and they are updated quickly. The traditional sheet metal processing parts of agricultural machinery products usually use punching methods, and the mold loss is large. Usually a large agricultural machinery manufacturer is used for The warehouse where the molds are stored is nearly 300 square meters. It can be seen that if the processing of parts is still in the traditional way, it will seriously restrict the rapid upgrading of products and technological development, and the advantages of laser flexible processing are reflected.

70% of the links in mobile phone processing and manufacturing are applied to laser technology and laser manufacturing equipment. Especially in recent years, the development of high-power, high-energy UV marking machine, deep UV and ultrafast laser processing technology has promoted the development of smartphone manufacturing technology. This is related to the nature of laser technology and the nature of precision manufacturing of mobile phones. On the one hand, due to the outstanding characteristics of lasers such as high power density, good directionality, cleanliness, high efficiency, and environmental protection, the trend of laser processing technology to replace traditional processing technology is accelerating. The advantages of cutting machines and other aspects are very obvious. On the other hand, mobile phone processing is the crystallization of a precision manufacturing technology, which requires micro-processing manufacturing equipment.

Laser drilling is one of the important mobile phone processing application technologies. The laser focusing spot can focus on the order of a wavelength and concentrate high energy in a very small area. It is especially suitable for processing fine and deep holes. The minimum aperture is only a few microns, and the ratio of hole depth to aperture can be greater than 50 microns. In mobile phone applications, laser drilling can be used for PCB board drilling, shell receiver and antenna drilling, earphone drilling, etc. It has the advantages of high efficiency, low cost, small deformation, and wide application range. There are more than 200 parts and components in one slap of the mobile phone, and its processing and manufacturing technology can be regarded as one of the most difficult production and manufacturing technologies. More than 200 parts such as LPC, camera, LCD, LCD screen, circuit board, antenna, etc. are processed, inlaid, and integrated together in a space that is a little wider than half a finger, a finger is longer, and a centimeter higher. High precision is required. Laser technology is an important technology that promotes the rapid rise of China's mobile phone manufacturing industry.
