Taking the manipulator technology as the design basis, the overall structure, execution structure, drive system and control system are designed. A sorting manipulator based on PLC and pneumatic control is proposed to sort the products. Through in-depth study on the realization of sorting function, careful analysis of the advantages and disadvantages of the control system and hardware selection, some optimizations were carried out on the basis of the realization of sorting function, and a series of design drawings such as the corresponding circuit wiring diagram were drawn. A simple, easy-to-operate a...
