International customary classification, laser products include laser processing, medical, printing, optical storage, including collimation, detection, civic education in a variety of laser instruments and equipment, laser devices and communications laser components and laser materials and components 11. The fastest growing in China's largest sales volume of Laser Ranging and Collimation Laser Processing (in the last two years, YAG laser processing equipment has been growing at a rate of 46%-60%, and up to 90 trillion yuan, surpassing CO2 laser processing equipment). Laser medical market developed earlier, once the high speed growth, but in a depressed state, sales hovering at 55 million dollars. High-end market is almost entirely occupied by foreign products, but the development of Tianjin University, TD-98 type Q-switch ruby laser therapy machine to win the quality, through the U.S. FDA and export volume. In 1998, the classification of laser varieties show that there are 37.4% of solid-state lasers, semiconductor lasers accounted for 18.5%, showing a strong market for solid-state lasers, semiconductor lasers, the rapid growth of the trend. Diode-pumped solid-state lasers (pulsed, continuous, single-mode frequency-stabilized, microchip, frequency-doubling) will become a new growth point.
Pneumatic marking machine principle of operation
To print Chinese and English characters, graphic computer input content, computer marking software content is converted into digital control signals sent to the print controller, the drive to play the workpiece on the successive grid composed of characters and graphics; needle in the X-Y two by a set of trajectory of the two-dimensional plane, while in the role of compressed air in the print needle on the surface of the workpiece on the surface of the workpiece under the action of the compressed air of the printing needle, in order to print the concave mark consisting of a dense matrix of dots.
