摘　　要：汽车上有许多塑料材质的饰件,通过电镀工艺可增加装饰性、提高硬度和耐磨性。饰件在安装时利用自身卡扣或者进行超声焊接,由于工艺需要,卡扣及焊接处不能被电镀,需涂绘阻镀漆实现这些位置的防护。因汽车更新换代迅速,饰件需求量大,并且种类繁多、形状复杂,阻镀涂绘工作劳动强度较高。为解决这一现状,研制阻镀漆智能涂绘生产线,利用机械手实现阻镀漆自动化涂绘。生产线设计为多工位,机械手循环作业方式。鉴于饰件单批次数量少、种类多,设计为三种类型饰件同时涂绘,设计气动快速夹具系统实现三维复杂饰件的平面内定位;针对不同类型饰件涂绘出漆量、涂绘速度不同,设计出漆自动控制系统;针对阻镀漆易固化堵塞管线的特性,设计自动气、液冲洗系统。经实验验证,气压设定误差±0.5%范围内,不影响涂绘效果;气动夹具系统配合机械手视觉实现涂绘位置的精确控制,重复定位精度可达0.1 mm;通过自动气、液冲洗系统清洗管线回路后,系统长时间停机可保证不发生堵塞。There are many plastic decorative parts on cars,which are electroplated to increase decoration,hardness and wear resistance.Decorative parts in the installation of their own buckle or ultrasonic welding,due to the needs of the process,buckle and welding can not be electroplated,paint resistance plating to achieve the protection of these positions.Due to the rapid replacement of automobiles,the demand for ornaments is large,and there are many types and complex shapes,so the labor intensity of resistance plating and painting is high.In order to solve this problem,an intelligent production line for resistance coating was developed,and a mechanical hand was used to realize automatic resistance coating.The production line is designed for multiple stations and the manipulator circulates.In view of the small number and variety of ornaments in a single batch,three types of ornaments are designed to be painted at the same time.The pneumatic rapid fixture system is designed to realize the in-plane positioning of three-dimensional complex ornaments.The automatic control system of paint is designed according to the different paint quantity and painting speed of different types of ornaments.The automatic gas and liquid flushing system is designed to prevent the coating from curing and block the pipeline.Experimental verification,the pressure setting error within the range of±0.5%,does not affect the painting effect;Pneumatic fixture system with manipulator vision to achieve precise control of the painting position,repeated positioning accuracy up to 0.1mm;After cleaning the pipeline loop by automatic gas and liquid flushing system,the system can be shut down for a long time to ensure no chemical blockage.
