Laser marking is to use very fine spot to play all kinds of symbols, characters, patterns and so on. The spot size can be in micron scale. It has a deeper meaning for micro work or anti-counterfeiting.
After focusing, the very fine laser, like a sharp knife, removes material from the surface of the object by itself. The biggest advantage is that the process of marking is non-contact processing, will not produce negative scratches and friction, and will not cause extrusion or pressure injury. Therefore, the goods to be processed will not be damaged. As the laser beam is re focused, the spot becomes smaller, the thermal effect area is small, and the processing is accurate, so some conventional processes which can not be completed and can not be realized can be completed.
With the help of modern laser processing CAD/CAM software, to achieve any form of sheet cutting, the laser processing, not only fast processing speed, high efficiency, low cost, and avoid the mould replacement, shorten production preparation cycle time. The utility model has the advantages of easy realization of continuous processing, short laser beam transposition time, and improved production efficiency. Various workpieces can be alternately installed. When a workpiece is machined, 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 development direction of modern metal processing because of its high speed, high precision, high quality, energy saving, environmental protection and so on. Laser cutting accounts for 32% of the market share in laser processing applications. The biggest difference between laser cutting and other cutting methods is that it has the characteristics of high speed, high accuracy and high adaptability. At the same time also has a small slot, small heat affected zone, good cutting surface quality, cutting noise, cutting edge, cutting edge smooth, vertical cutting process is easy to realize automation control etc.. When cutting the sheet metal, no die is needed, which can replace the punching and cutting method of complex large mold, which can greatly shorten the production cycle and reduce the cost.
Sheet metal processing is the key technology that sheet metal technicians need to master, and it is also an important process of sheet metal forming. It includes not only the traditional cutting, punching, bending forming method and process, including cold stamping die structure and process parameters, working principle and operating method of all kinds of equipment, new technology and new stamping process also includes. Fabrication of agricultural products generally use the 4-6mm steel plate, sheet metal species, and updated quickly, agricultural products fabrication usually use a punch, die loss, usually a large agricultural machinery manufacturer for mold storage warehouse near 300 square meters, thus, parts processing if you still stay in the traditional the way, fast update will seriously restrict the upgrading of products and technology development, and the advantages of laser flexible processing is reflected.
Mobile processing 70% of the link is 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 smart phone manufacturing technology. This is related to the nature of laser technology and the precise manufacture of mobile phones. On the one hand, because the laser has high power density, good directivity, clean, efficient and environmentally friendly features, laser processing technology to replace the traditional processing technology of the trend is accelerating, the micro processing advantages of laser welding machine, laser marking machine, cutting machine and other advantages in the laser is very obvious. On the other hand, cell phone processing is a crystallization of precision manufacturing technology, the need for micro processing equipment.
Laser drilling is one of the most important mobile phone processing technologies. Laser beam can get the order of the wavelength, high energy concentrated in a small area, especially suitable for machining micro hole, the minimum aperture of only a few microns, hole depth and aperture ratio greater than 50 microns. Laser drilling in the mobile phone applications can be used for PCB plate punching, shell, receiver and antenna drilling, headset drilling, etc., with high efficiency, low cost, small deformation, wide range of advantages. A mobile phone palm place focus on more than 200 parts, its manufacturing technology is one of the difficult technology in manufacturing. In a half finger a little wider, a long point, a high point cm space, LPC, camera, LCD, LCD screen, circuit board, antenna and other more than 200 parts processing, mosaic, together, its high precision requirements. Laser technology is an important technology to promote the rapid rise of mobile phone manufacturing industry in china.
