摘　　要：针对市场上工业贴片机成本较高的问题,提出了面向中小型企业及实验室的经济型贴片机。首先从合理选择X-Y-Z轴传动机构入手,由步进电机带动同步带取代传统的伺服电机带动滚珠丝杠的传动,实现X-Y轴的运动;贴装头部分由凸轮传动取代滚珠丝杠传动,实现Z轴的进给运动;按照传动要求,对凸轮结构进行了设计;然后对视觉识别系统进行分析,确定获取清晰元器件轮廓的最理想图像处理算法,并建立常用元件图像库,完成视觉识别系统设计。经过以上工作,该贴片机具有体积紧缩,低成本的优势,具有一定的节约应用价值。According to the higher cost of industrial SMT machine in the market,we put forward the design of economical SMT machine system to use in small business and laboratory.At first,we start from a reasonable choice of X-Y-Z transmission mechanism.We adopt the stepping motor drive synchronous belt transmission to take the place of the servo motor drive the ball screw transmission to accomplish X-Y axis movement.Using the cam-gear to replace the lead screw drive to complete the Z axis movement and focusing on the design of the cam＇s structure.All about those are to make the reduction of SMT machine＇s cost.Then the visual identity system are analyzed and to determine the most ideal algorithms of the clear outline of components involved in image processing.We use the processed images to establish a common element image library and thus complete the design of Visual Identity System; All of those improvements make the SMT machine＇s cost and the volume reduced.As the result,the economical SMT machine has certain practical value.
