中文摘要:
      在喷涂机器人自动喷塑过程中,静电装置和喷嘴内部易产生粉末涂料堆积的问题,因此课题组基于SolidWorks 2016软件建立了喷头三维模型;使用ANSYS17.0的FLUENT模块对喷头进行流体仿真分析,发现喷头内部结构设计不合理。然后对喷头进行结构优化:将静电装置中原先的单条4 mm宽度横梁改成3条按等边三角形分布的1 mm宽度的横梁,同时将内芯的圆柱体改成圆锥体;使用斜面喷嘴代替整平面喷嘴,并对斜面角度进行研究,发现45°角斜面是最合适的角度。静力学分析结果表明:改进后喷嘴内粉末不易堆积,优化设计达到了要求。
英文摘要:
      Aiming at the problem that the accumulation of powder paint was easily occurred in electrostatic devices and nozzles in the automatic spraying process of the spraying robot, a three dimensional model of the nozzle based on SolidWorks2016 software was established and the FLUENT module of ANSYS17.0 was used to perform fluid simulation analysis on the nozzle. It was found that the design of the interior structure of the nozzle was unreasonable, and anoptimization of the nozzle structure was proposed. The original single 4 mm width beam in the electrostatic device was changed to three 1 mm width beams distributed according to an equilateral triangle and the inner cylinder was changed to a cone; the bevel nozzle was used to replace the full plane nozzle, and the angle of the bevel angle was studied.The results show that the 45 bevel is the most suitable angle. The static analysis results show that the powder in the improved nozzle is not easy to accumulate and the optimized design meets the requirements.
