摘　　要：针对目前移液器装载机的欠缺,课题组设计了一种新型吸头自动装载系统。采用模块化的设计思想,设计了自动送料机构的3个模块:自动送料模块、输送模块以及装盒模块,实现了吸头的自动整理上料;采用解析法分析了凸轮的运动理论以及吸头的输送过程;采用ADAMS虚拟样机技术对自动送料和输送过程进行了仿真分析。仿真结果表明该吸头自动送料机构能够满足吸头自动装载的应用要求。该装置不但适用于移液器吸头的自动送料,对其他小零件送料也有一定的借鉴意义。In view of the shortcomings of the current transporter loader for pipette tip,a new type of pipette tip automatic loading system was designed by the research group. Using modular design idea,three modules of automatic feeding mechanism were designed,including automatic feeding module,conveying module and boxing module,which realized the automatic sorting and feeding of pipette tips;the movement theory of cam and the conveying process of pipette tips were analyzed by analytic method;and the simulation analysis and theoretical calculation of automatic feeding and conveying process were carried out by using ADAMS virtual prototype technology. The simulation results show that the pipette tip automatic feeding mechanism can meet the application requirements of pipette tip automatic loading. The device is not only suitable for automatic feeding of pipette tip,but also has important reference significance for feeding other small parts.
