According to the classification method of international practice, laser products include laser processing, medical treatment, printing and optical storage, including various laser instruments and equipment in collimation, detection and civic education, laser devices and communication laser components and laser materials and components 1 1. , the fastest growing laser ranging collimated laser processing in China (the growth rate of YAG laser processing equipment in recent two years is 46%-60%, reaching 90 trillion yuan, exceeding that of CO2 laser processing equipment). The laser medical market developed earlier. Once it grew at a high speed, it fell into a downturn, with sales hovering at 55 million yuan. The high-end market is almost completely occupied by foreign products, but the TD-98 Q switched ruby laser therapeutic machine developed by Tianjin University wins by quality and has passed the US FDA and export volume. The classification of 1998 lasers shows that solid-state lasers account for 37.4% and semiconductor lasers account for 18.5%, which shows that the solid-state laser market is strong and the semiconductor lasers are growing rapidly. Diode-pumped solid-state lasers (pulsed, continuous, single-mode frequency stabilization, microchip, frequency doubling) will become new growth points.
Working principle of pneumatic marking machine
The computer input content and computer marking software content for printing Chinese and English characters and graphics are converted into digital control signals and sent to the printing controller, and the driver plays the characters and graphics composed of continuous grids of the workpiece; The needle is on the X-Y two-dimensional plane with a set of tracks, and under the action of compressed air of the printing needle, it is on the surface of the workpiece, thus printing gravure printing composed of dense lattice.
