Application of pneumatic technology
People use air power to complete all the work dates back to ancient times, but as the prototype of pneumatic technology, some began to produce the invention in 1776 of about 1 atmosphere pressure air compressor. In 1880, the first time made use of pneumatic brake cylinder device, it successfully applied to the brake on the train. The early 30s of this century, pneumatic technology successfully used in automatic door opening and closing and a variety of mechanical action on the auxiliary. Into the 70's, along with the development of industrial mechanization and automation, pneumatic technology was widely used in various fields of automation, the formation of modern aerodynamic technology. (1) automotive industry Hyundai Motor Manufacturing plant production lines, especially the major production line welding process, almost without exception, use of pneumatic technology. In each process, such as body movement, body shell is a vacuum suction cups pick up and drop, for a specific station clamping and positioning, spot welding head of the fast approaching, slow swing control of a soft landing spot after all used a variety of special features of the pneumatic cylinder and the corresponding control system. High frequency welding, force control accuracy and complete the whole process highly automated process, called the most representative one of the pneumatic technology applications. In addition, the handling equipment used in high-speed cylinder (the maximum speed of 3m / s), the proportion of composite control valve control technology represents a new development of today's pneumatic technology. (2) electronics, semiconductor manufacturing industry in color television sets, refrigerators and other household product assembly production line in semiconductor chips, printed circuits and other electronic products assembly lines, not only can see a variety of sizes and shapes of different cylinder, Gripper, you can also see a lot of smart vacuum suction will generally difficult to grab the tube Gripper, cartons and other items gently suck, transported to the designated location. Very strict limits on the acceleration of the chip removal system that uses a smooth acceleration of the SIN cylinder. (3) 60 years to achieve automation, pneumatic technology is mainly used to compare areas of heavy job as an auxiliary drive. In the sewing machines, watches, bicycles, washing machines, automatic and semi-automatic machine tool parts and many other industries processing and assembly line, work piece handling, transfer, positioning, clamping, feeding, handling, assembly, cleaning, inspection, and many other processes use pneumatic technology. (4) the realization of automated packaging technology is also widely used in Pneumatic fertilizer, chemical, food, food, medicine and many other industries, to achieve powder, granular, automated measurement of bulk material packaging for the tobacco industry's automatic and automatic packaging of cigarettes and many other processes, used for viscous liquids (such as paints, cosmetics, toothpaste, etc.) and automatic measurement of toxic gases filling.
