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 rapid development. In the modern industry, the production process of mechanization, automation has bee a prominent theme. However in the mechanical industry, machining, assembly and other production is not continuous. Rely on human these discontinuities in the cow process joins up, not only timeconsuming and inefficient. At the same time, the labor intensity is very large, sometimes there will be errors and injuries. Obviously, the serious influence restricts the entire production process efficiency and automation degree. Application of mechanical hands is a very good solution to this situation, it is not the presence of repetitive accidental error, also can effectively avoid accidents ( Yang Yongqing, 2020). In the mechanical industry, mechanical hand application has the following meanings. The application of the manipulator, is beneficial to improve the material conveyor, workpiece loading and unloading, cutter replacement and assembly of the machine and the degree of automation, thereby can improve labor productivity, reduce the production cost, accelerate the realization of industrial production mechanization and automation. In high temperature, high pressure, low temperature, low pressure, dust, noise, odor, radioactive or other toxic pollution and limited working space and other occasions, with manual operation is dangerous or impossible. Application of mechanical hand can replace some or all of the safety work, greatly improves the working conditions. At the same time, in some simple action but a repeat operation operation, with mechanical hand instead of manual work, to avoid the operation fatigue or negligence caused the accident. Application of mechanical hand instead of manual wor
