摘　　要：速度和精度是衡量贴装机性能的关键参数，而对中系统是贴装机在进行贴装时处理片式元器件特征和位置反馈的关键系统，它直接决定了贴装机的速度和精度。文章详细阐述了贴装机对中系统的分类，分析了视觉对中系统的原理，进而分析了影响贴装机视觉系统光学洼能的主要参数，以便相关人员更好地了解当今高精度贴装机的图像处理技术是如何适应器件高精度贴装的需求。The speed and the precision are important parameters of the measure ot mounting mncuon, and alignment system is the key part to analyze the characters and positions of the chip components during the placement. It determines the speed and the precision of the mounting. In order to be further understand how the image processing technology can fulfill the high-precision placement requirement, the article introduces the sorts and the principle of the mounting alignment system and then analyses the main parameters which affects the optical function of the mounting alignment system.
