摘要
为了满足在平板显示贴附类设备中对高精度贴合的要求,设计了一种平面3-PRP型并联机构UVW工作平台,并对平台的自由度进行了分析,利用解析法给出了平台精确的运动学正反解模型,并在此基础上对平台产生误差的原因进行了深入分析。在平台的各种误差中,PRP支链的对心误差是导致运动学正反解误差的关键,是影响平台精度的主要原因。
In order to meet the requirements of high precision fitting attached equipment in the flat panel display, a kind of UVW working platform of 3-PRP parallel mechanism of plane was designed, and the degree of freedom of the platform were analyzed, and the analytical model of kinematics of the positive and negative was give by analytical method, the errors of the platform are analyzed in depth based on former research.In all kinds of errors of the platform, the central error is the key to the error of positive and negative solution of kinematics in the chain of PRP, which is the main reason of the platform precision.
