贴片机x-y运动横梁结构设计研究

高速、高精度是贴片机的主要特征。在框架式贴片机中,横梁的质量与刚度是决定整机速度和精度的主要因素。横梁的结构形式、与传动机构的连接方式、材料等都直接影响横梁的质量与刚度值。通过综合分析传动机构与横梁不同连接方式的利弊,从中选择能够满足设计要求的连接方式。在此基础上,对横梁结构进行数值仿真分析与优化,从而达到了降低横梁质量、提高刚度的设计目的。

Design Research on x-y Moving Beam of Placement Equipment

High speed and high precision are the principal characters of the placement machine. In the frame placement machine, the mass and stiffness of the beam are the major factors that impact the speed and precision of the whole machine. The structure form of the beam, and the connection way to the transmission-mechanism and the material affect the mass and stiffness of the beam all directly. The advantages and disadvantages of the connection way of the transmission-mechanism and the beam are analyzed, and the connection way being able to satisfy the design demand is chosen. Lastly, the beam structure is analyzed and optimized by simulation so that the beam mass is reduced and the stiffness is improved.
