the accident. Application of mechanical hand instead of manual work, which is directly reduced the human one side, at the same time as a result of the application of the manipulator can be continuously, it is to reduce the human to another side. Therefore, in the automation of machine tools and processing automatic production line almost at present is provided with mechanical hands, in order to reduce manpower and to more accurately control the production rhythm, facilitate rhythmic production. With the development of modern industrial technology, industrial automation technology is more and more high, the working environment of workers and working content requirements of ideal and simple, for some reciprocating work by robot remote control or automatically is very important. This can avoid some people cannot contact material harm to human body, such as metallurgy, chemical, pharmaceutical, aerospace and other. The manipulator on the domestic and foreign research level is not a, but represent the most advanced technology in Japan, his automation, humanity is as the acme of perfection, these techniques rely on control theory, new material science, it is the integration of a variety of cuttingedge technology and modern machines. Our country also gradually in the industry has been applied, for automatic control, flexible manufacturing system in the application of more extensive, but China39。PLC manipulator control system Machinery industry is the national equipment department, national economy is to provide equipment and life for the people to provide durable consumer goods industry. Machinery industry scale and technical level is to measure a country 39。s economic strength and scientific and technological level of an important symbol. Therefore, all countries in the world the development of machinery industry as national economy development strategic point of ( Zhang Zhixian, 2020). The new century, the level of production and the continuous progress of science and technology and development to the entire machinery industry39。s automation level remains to rise, only the equivalent of the world advanced technology in the level of eighty time. With the development of industrial modernization, robot technology has also increased, the development trend is the working strength is high, flexibility, accurate and reliable, can automatical
