【正文】 r module, sensor, photoelectric encoder ,pneumatic ponent and so on. It controls manipulator move vertically or horizontally, chassis or paw rotate, packandplace. The design mainly uses stepping sequence control and stepping control technology. The process covers programmable control technology, position control technology, detection technology, which is a typical representative of mechatronics. The design report firstly describes how to choose the way to control the mechanical hand and introductions of the ways. Then introduces the design steps. It also introduces program test of the manipulator. At last, the paper introduces the steps of processing and monitoring manipulator by KingView. 【 Key words】 : mechanical hand PLC ball screw step contr西南科技大學(xué) 本科生畢業(yè)設(shè)計(jì)（論文 ） 1 目錄 一、 緒論 ....................................................................................... 3 （一） 課題研究目的及意義 ....................................................................................................... 3 （二） 國(guó)內(nèi)外機(jī)械手研究概況 .................................................................................................... 3 ............................................................................................................................. 3 ............................................................................................................................. 3 二、 機(jī)械手控制 方式選擇 ........................................................... 5 （一）機(jī)械手常用控制方法 ......................................................................................................... 5 1．控制方式的分類 ................................................................................................................ 5 ........................................................................................................ 6 （二） PLC 簡(jiǎn)介 .......................................................................................................................... 6 組成 ............................................................................................................................. 8 的特點(diǎn) ......................................................................................................................... 8 3.
