【摘要】：在汽车、家电等行业中表面涂装是生产过程中关键一步,对喷涂质量和成本的把控也越来越严格。因此,静电喷涂机器人在这些行业中得到了越来越多的应用。喷涂工件表面外形,旋杯电压、喷枪运动速率等参数,还包括最终喷涂轨迹的设置,都决定着漆膜质量的好坏。离线仿真技术正朝着和CAD系统相结合的发展趋势发展,实现了CAM/CAD/ROBOTICS一体化,促使机器人运行安全性增强,降低机器人空闲时间且压低了运行成本。机器人在给工件喷涂时常常采用固定的喷涂参数,因为那些工件表面曲面平缓、表面结构不复杂。但是随着当今工业产品的多样化,其表面构造越来越复杂,仍然以固定喷涂参数对复杂曲面工件喷涂已经不能达到所需喷涂质量的要求,且不能发挥喷涂机器人的优势。所以变量喷涂的方法应运而生,在曲面不同位置设置不同的喷涂参数,以使喷涂机器人在工件各个位置都能保证漆膜均匀平滑,同时以最节省涂料的方法完成喷涂任务。本文尝试结合CATIA V5二次开发、ROBCAD离线仿真、并利用变量喷涂的方法来编制喷涂机器人离线程序。在变量喷涂的方法指导下,利用CATIA CAA二次开发出喷涂辅助工具;在CATIA环境下利用二次开发软件处理喷涂模型;利用ROBCAD实现离线仿真编程,并导出机器人离线程序。
[Abstract]:Surface coating is a key step in the production process in automobile, home appliance and other industries, and the control of spraying quality and cost is becoming more and more strict. Electrostatic spraying robot has been used more and more in these industries. The surface shape of spraying work piece, rotor voltage, spray gun movement rate and other parameters, including the setting of the final spray trajectory are also included. Off-line simulation technology is developing towards the combination of CAD system and the development trend, realizing the integration of CAM/CAD/ROBOTICS. In order to improve the safety of the robot, reduce the idle time of the robot and reduce the running cost, the robot often uses the fixed spraying parameters when spraying the workpiece because the surface of the workpiece is flat. The surface structure is not complex, but with the diversification of industrial products, its surface structure is becoming more and more complex, still with the fixed spraying parameters to complex surface parts spraying can not meet the requirements of the required spraying quality. And can not play the advantages of spraying robot, so variable spraying method came into being, in different positions of the surface set different spraying parameters, in order to ensure that the spraying robot in every position of the workpiece uniform smooth film. At the same time, the method of saving coating is used to finish the spraying task. In this paper, we try to develop off-line simulation of CATIA V5 in combination with CATIA V5. The off-line program of the spraying robot is programmed by the method of variable spraying. Under the guidance of the method of variable spraying, the auxiliary tool of spraying is developed twice by using CATIA CAA. The spray model is processed by using secondary development software in CATIA environment. The off-line simulation program is realized by ROBCAD, and the robot off-line program is derived.
