1、摘要為工業(yè)機(jī)械手研制一個(gè)技術(shù)性能優(yōu)良的控制系統(tǒng)，對(duì)于提高工業(yè)機(jī)械手的整體技術(shù)性能來說具有十分重要的意義。本論文正是針對(duì)這一課題，選擇了可編程控制器(PLC)作為工業(yè)機(jī)械手的控制系統(tǒng)，這對(duì)提升工業(yè)機(jī)械手的整體技術(shù)性能起到了良好的作用。本論文的控制對(duì)象是由三個(gè)搬運(yùn)機(jī)械手組成的機(jī)械手群，每個(gè)機(jī)械手完成八個(gè)基本動(dòng)作，三個(gè)機(jī)械手互相配合動(dòng)作。機(jī)械手由氣缸驅(qū)動(dòng)，氣缸受電磁閥控制。限位開關(guān)檢測(cè)機(jī)械手是否到達(dá)固定位置?？删幊炭刂破?PLC)控制每個(gè)機(jī)械手的動(dòng)作，實(shí)現(xiàn)機(jī)械手群的自動(dòng)運(yùn)行。本論文可編程控制器(PLC)選用西門子（SIEMENS）公司S7–200系列的CPU224，并擴(kuò)展了E
