ABSTRACT
The mechanical hand is to improve labor productivity, improve working conditions, reduce the labor intensity of workers and an important means to realize the automation of industrial production, is currently being widely applied to industrial production
This subject mainly design a X-Y screw automatic assembly machine hand, can make the screw in the plane according to the requirements of automatic assembly screws. Research papers to X-Y mechanical hand and screw assembly device research as the main body, the use of programmable controller as the main control unit of the control system, using industrial control technology, the realization of full automatic control of screw assembly machine. The combination of stepping motor and servo motor is used to assemble the screw, which makes the assembly screw fast and accurate. At first, the paper introduces the automatic screw assembly manipulator control system and its implementation, then the part of the structure, function, the work flow and so on are described, finally complete electrical principle diagram design, 2D mobile manipulator PLC control programming and control system implementation. In order to achieve the screw can be automatically assembled on the plane according to the requirements of the threaded hole plate, and realize the automation of the system requirements.
