Title Analysis and Optimization Design of Wheel Production System —— the Design of Intelligent Spraying Robot
Abstract
In recent years, due to the rapid development of China's automobile industry, opportunities and challenges have brought to China's auto parts makers. Wheel hub is one of the most important parts of a car. According to the existing wheel production line of the SMD Wheel Co. , Ltd, an intelligent hub spray painting robot for replacing the traditional manual spraying is introduced in this paper. In the intelligent spray painting robot, photoelectric sensors are used to test the hub’s presence and size and Siemens S7-200 SMART PLC is used to control the operation of three stepping motors. The synchronous belt is used to drive the spraying guns moving along the rail.
In this paper, dimensions of synchronous belt have been accurately calculated and the appropriate fit of the shaft has been selected; the driving shaft has also been checked, and the result shows that the designed shaft can meet the strength requirements; the wheel detection scheme for the spraying robot has been designed, and the control system has been designed.
