汽车轮毂自动喷涂系统的设计

摘要

Now the job of automotive wheel spraying is done manual y in lots of domestic SMEs, which greatly affects the health of workers and also shows a low degree of automation. The paper designs an automatic spray system that can spray the wheels of dif-ferent size continuously. Three spray guns with sprocket chain and rol er slide rail are used to spray the upper and side surface of wheel simultaneously. The control system is equipped with PLC, encoders and light curtain are used to detect the speed of wheel transport line and wheel condition intel igently.%许多国内中小企业对于汽车轮毂的喷涂都采用手工喷涂，这极大影响工人的身体健康，且自动化程度较低。设计了一种可对轮毂进行连续自动喷涂的简单喷涂系统。采用了链传动、滚轮滑轨等机械结构，使用3把喷枪对轮毂上表面及侧面分别同时进行喷涂；以PLC为控制核心，采用编码器及光幕传感器对轮毂运输线速度及轮毂情况进行智能检测，实现对喷枪喷涂动作自动控制。系统可对不同尺寸的轮毂进行连续自动的喷涂。
