%X LED粘片机在正常工作时，摆臂往往存在运动不平稳、振幅较大及趋稳时间较长等问题，影响粘片效率与精度。通过分析摆臂的整个运动过程，提出新的设计方法。首先，利用5次多项式运动曲线来替代梯形运动曲线，保证摆臂运动过程的平滑性；其次，结合静力学分析、模态分析及瞬态动力学分析，对摆臂进行外形优化设计；然后，为减少摆臂转动惯量对运动的影响，对摆臂进行拓扑优化，得到摆臂的优化模型；最后，通过瞬态动力学分析验证，证实了此方法的可行性。<br>In normal operation of swing bar of LED Bonder, there exist the questions of the non-stability, large amplitude and long settling time. These questions affect the efficiency and accuracy of LED Bonder. By analyzing the whole swing bar movement a new design method is proposed. Firstly, the quintic polynomial motion curve is used instead of trapezoid motion curve to ensure the stability of the swing bar in the moving process. Secondly, the shape of the swing bar is optimized with the results of the static analysis, modal analysis and transient dynamics analysis. Then, topology optimization is carried out on the structural design of the swing bar to reduce the influence of moment of inertia and get the optimization model. Finally, the feasiblity and effectiveness of this method are verified with the results of transient dynamics analysis
