【摘要】：建立机器人喷涂涂层厚度分布数学计算模型,优化平面喷涂轨迹,求出最佳喷涂步距,获得平整连续的涂层。通过设计单点喷涂试验,获得不同喷涂时长所对应的涂层厚度最大值,用MATLAB软件拟合涂层厚度与时间的关系函数。利用高斯模型建立机器人喷涂涂层厚度分布数学模型,根据该模型获得喷涂点叠加函数。最后利用MATLAB软件进行模拟。结果表明:建立的涂层厚度分布数学模型与实际喷涂涂层厚度分布基本吻合。连续喷涂过程中喷涂点的叠加是以三个喷涂点为周期,在该模型的基础上计算出的最佳步距能获得平整连续的涂层。
[Abstract]:A mathematical model of the thickness distribution of the robot spray coating was established to optimize the plane spray trajectory, to obtain the best spray step, and to obtain a flat and continuous coating. The single point spraying test was designed. The maximum coating thickness corresponding to different spraying time was obtained, and the relationship function between coating thickness and time was fitted by MATLAB software, and the mathematical model of coating thickness distribution of robot spraying was established by Gao Si model. According to the model, the superposition function of spray point is obtained. Finally, the simulation is carried out by using MATLAB software. The results show that:. The mathematical model of coating thickness distribution is basically consistent with the actual coating thickness distribution. The superposition of spray points in the process of continuous spraying takes three spraying points as the period. On the basis of the model, the optimum step distance can be obtained by a flat and continuous coating.
