Title The Design of Intelligent Spraying Robot Used in Spraying Production Line

Abstract This paper mainly described the intelligent spraying robot used in spraying the hub. This Spraying robot selected the highly stable, well-extended Siemens PLC S7-200 as its controller, and used screen sensor to measure the width of to-be-sprayed rims. It realized the movements of the robot’s spraying guns by controlling the two explosion-proof motors , and used two position sensors to assist the spraying robot to reset itself. It used the chain and chain gear and the roller guide rail against dust. This paper designed of the mechanism to change the chain turnover motion into linear reciprocating motion of the spaying guns, which avoids of the frequent reciprocating motion when spraying task is heavy.

This paper has taken accurate calculation to the key parts -- dimensions of chain and sprocket. It also checked the dangerous driving shaft, which showed that the design of the shaft drive meets the strength requirements. It also did the research and design of control system of the spraying robot. Therefore, when the control system is reasonable, the spraying robot can achieve predetermined spraying function, whose structure strength can satisfy the security requirements of the work. As a result, the spraying machine has a certain practical value.
