4.旋轉(zhuǎn)編碼器

在可回旋360°的轉(zhuǎn)盤機(jī)構(gòu)上，安裝有OMRON公司生產(chǎn)的E6A2增量型旋轉(zhuǎn)編碼器，編碼器將信號傳給PLC，實現(xiàn)轉(zhuǎn)盤機(jī)構(gòu)的精確定位。

5.PLC的選型

根據(jù)系統(tǒng)的設(shè)計要求，選用OMRON公司生產(chǎn)的CPM2A小型機(jī)。CPM2A在一個小巧的單元內(nèi)綜合有各種性能，包括同步脈沖控制、中斷輸入、脈沖輸出、模擬量設(shè)定和時鐘功能等。CPM2A的CPU單元又是一個獨立單元，能處理廣泛的機(jī)械控制應(yīng)用問題，所以它是在設(shè)備內(nèi)用作內(nèi)裝控制單元的理想產(chǎn)品。完整的通信功能保證了與個人計算機(jī)、其它OMRONPC和OMRON可編程終端的通信。這些通信能力使四軸聯(lián)動簡易機(jī)械手能方便的融合到工業(yè)控制系統(tǒng)中。

三軟件編程

1.軟件流程圖

流程圖是PLC程序設(shè)計的基礎(chǔ)。只有設(shè)計出流程圖，才可能順利而便捷地編寫出梯形圖并寫出語句表，最終完成程序的設(shè)計。所以寫出流程圖非常關(guān)鍵也是程序設(shè)計首先要做的任務(wù)
