长尾夹自动装配系统上料卸料同步装置研究

Loading and unloading synchronous device for automatic assembly machine for binder clips

针对长尾夹自动装配系统装配过程中上料卸料的欠缺和低效等问题,对自动装配系统上料卸料机构进行了研究,提出了新型的间歇性双段推板上料卸料同步装置,利用该同步装置实现了对未装配夹体进行上料和对已装配好的长尾夹进行卸料。利用西门子公司的S7-200系列PLC控制器对长尾夹装配机进行了上料卸料、输送、装配的系统控制,实现了过程中的自动装配。利用Matlab软件中的Simulink仿真工具对自动装配系统的上料卸料气缸进行了动力学仿真,通过仿真确定了上料卸料气缸在充气推出过程中的各个参数值,得出了工作气压最优值和平台的装配效率。研究结果表明,上料卸料同步装置装配在气缸压强为0.2 MPa,上料卸料时间为0.693 s时的工作效率最高,容错率更低,可有效取代人工上料卸料。

Aiming at the problem of the defect and inefficient of the binder clips automated assembly system assembly loading and unloading process,a new loading and unloading synchronization device which was two-stage intermittent push plate was proposed. This synchronization device was used to realize the function of unassembled clip body loading and assembled binder clip unloading. Using the Siemens S7-200 series PLC controller to roundly control loading and unloading device,transport device and assembly device,the automatic assembly machine were implemented. Based on the loading and unloading cylinder dynamics simulation with the Simulink simulation tool of Matlab,each parameter value in the process of pneumatic launch was determined,and the optimal value of working pressure and the platform assembly efficiency were worked out. The experimental results indicate that the loading and unloading synchronization device has highest work efficiency and the lower fault rate,which can effectively replace manual loading unloading,while the cylinder pressure is 0. 2 MPa and the loading and unloading time is 0. 693 s.
