Application Of Laser Marking Technology In Mobile Phone Manufacturing Industry

- Jun 09, 2017 -

Laser marking is a very small spot to play a variety of symbols, text, patterns and so on, spot size can be micron level. For micro-work plus or anti-counterfeiting has a deeper meaning.
After focusing the very thin laser like a sharp knife, the surface of the object can be removed by point. The greatest advantage is that the process of marking is non-contact processing, will not produce negative scratches and friction, nor will it cause compression or pressure injury and so on. Therefore, it will not damage the items to be processed. Because the laser beam again zoom after the spot becomes more small, the heat effect area is small, the processing is accurate, so can complete some routine cannot complete, cannot realize process.
Laser processing can use the modern CAD/CAM software, to achieve any form of plate cutting, the use of laser processing, not only processing speed, high efficiency, low cost, but also to avoid mold replacement, shorten the production preparation time period. It is easy to realize continuous processing, the laser beam transposition time is short and the production efficiency is improved. Multiple workpieces can be installed alternately. When a workpiece is processed, the finished parts can be unloaded and the workpiece to be machined will be installed in parallel processing to reduce the installation time and increase the laser processing time. Laser cutting with its high-speed, high-precision, high-quality, energy-saving and environmental protection characteristics, has become a modern metal processing technology development direction. In laser processing applications, laser cutting accounted for 32% of the market share. Laser cutting compared with other cutting methods, the biggest difference is that it has high-speed, high-precision and high adaptability. At the same time, it also has the advantages of small slit, small heat-affected area, good quality of cutting surface, no noise when cutting, good verticality of kerf edge, smooth trimming, and easy to realize automatic control during cutting. Laser cutting plate, do not need to die, can replace some of the need to adopt a complex large-scale die cutting processing methods, can greatly shorten the production cycle and reduce costs.
Sheet metal processing is the key technology that sheet metal technicians need to master, and is also an important process of forming sheet metal products. It not only includes the traditional cutting blanking, blanking processing, bending forming and other methods and processes, but also includes various cold stamping die structure and process parameters, various equipment working principle and operating methods, but also include new stamping technology and new technology. The sheet metal processing parts of agricultural machinery products generally adopt 4-6MM steel plate, many kinds of sheet metal pieces, and update quickly, traditional sheet metal processing parts of agricultural machinery products usually adopt punching method, die loss is large, usually a large-scale agricultural machinery manufacturers used to store the warehouse in the vicinity of 300 square meters, it can be seen that parts of the processing if still stay in the traditional way, will seriously restrict the rapid upgrading of products and technology development, and laser flexible processing advantages are reflected.
Mobile phone manufacturing 70% of the links are applied to laser technology and laser manufacturing equipment. Especially in recent years, the development of high power, high energy ultraviolet marking machine, deep ultraviolet and ultrafast laser processing technology has promoted the development of smartphone manufacturing technology. This is related to the nature of laser technology and the precise manufacture of mobile phone. On the one hand, because the laser has high power density, directional good, clean, high efficiency, environmental protection and other outstanding characteristics, laser processing technology to replace the traditional processing technology trend is accelerating, its micro-processing advantages in laser welding machine, laser marking machine, laser cutting machine and other advantages are very obvious. On the other hand, mobile phone processing is a precision manufacturing technology crystallization, the need for micro-processing manufacturing equipment.
Laser drilling is one of the most important applications in mobile phone processing. Laser focusing spot can gather a wavelength of magnitude, in a very small area concentrated very high energy, especially suitable for processing micro-deep hole, the smallest aperture only a few microns, depth and aperture ratio can be greater than 50 microns. Laser drilling in mobile phone applications can be used in PCB board drilling, Shell receiver and antenna drilling, headphone drilling, etc., with high efficiency, low cost, small deformation, wide range of application and so on. Mobile phone a big place to focus on more than 200 parts, its processing and manufacturing technology can be regarded as a more difficult production and manufacturing technology. In a half point slightly wider, a point of length, a centimeter high one points of space, the LPC, camera, LCD, LCD, circuit boards, antennas and other 200 parts processing, mosaic, integration, the precision of its requirements are high. Laser technology is an important technology to promote the rapid rise of China's mobile phone manufacturing industry.
