The manipulator based on PLC control system design
Abstract ：Handling machinery is widely used in mechanical processing automatic linelogistics system, it is one of the important equipment in automatic line. Handling machinery ismainly used for the movement of parts or finished products in fixed position, instead ofmanual work, especially in the toxic, flammable and explosive and other harsh environment,has been widely used. Mechanical handling hand is high degree, flexible action, instead ofmanual operation, accelerate the production cycle, greatly improve the production efficiencyand product quality of manufacturing enterprises. Industrial use of the handling of largemechanical hand larger, expensive. With the application of electromechanical integration invarious fields, automatic control component of mechanical equipment is increasinglyimportant, due to the need to work, people are often subjected to the harm of high temperature,corrosive and toxic gases and other factors, increases the labor intensity of workers, and even life-threatening. So manipulator is born in this way, the manipulator is the traditional taskexecution mechanism in the industrial robot system, and it is one of the key parts of the robot.According to the control requirement of this manipulator PLC control system hardware design,PLC programming and simulation debugging, make the manipulator to complete theprescribed function.Through this graduation design, to grasp the method of control project,the application of PLC in the real business, master the automatic control system for thecomplete analysis and design process, cultivating the practical ability to solve the problem ofthe similar projects.
