基于PLC的搬运机械手硬件系统设计

本文针对完成工件在两条生产线之间搬运任务的搬运机械手控制系统进行设计。采用了电气一体化的设计方案,使用气缸实现了机械手对工件的抓放,通过变频器控制异步电动机来实现机械手在水平、竖直方向快速精确的移动。采用三菱公司的FX2N系列PLC作为核心控制器,从硬件方面进行设计,完成了PLC在搬运机械手中硬件连接、I/O点分配以及界面的简单设计,实现了机械手的零点复位、故障报警、手动运行和在无人看守时的自动运行。最终达到设计要求,完成搬运目的。

The Design of Carrying Manipulator Hardware System Based on PLC

This paper aimed at designing the carrying manipulator handling mission control system which achieved the workpiece between two production lines. Adopting electrical integration design, we use a cylinder to realize the manipulator grasp and put the workpiece, through state of manipulator keep motor move quickly and accurately in level and the vertical direction. Adopt Mitsubishi company FX2N PLC as the core controller, designing from hardware, completed in handling mechanical hand PLC hardware connection, I/O point distribution and the interface, realizing the manipulator on zero reset, fault alarm, manual operation and the automatic operation when no keeping watch. Finally achived the design requirements and completed handling purpose.
