基于PLC的四自由度電動(dòng)機(jī)械手的控制設(shè)計(jì) 摘 要:所介紹的電動(dòng)機(jī)械手由電控機(jī)械手、yz軸絲杠組、手轉(zhuǎn)動(dòng)機(jī)構(gòu)、旋轉(zhuǎn)底盤等機(jī)械部分組成,在PLC控制下,它可在行程范圍內(nèi)將物體從一點(diǎn)搬運(yùn)至另一任意點(diǎn),可置放于各種不同生產(chǎn)線或物流流水線中。關(guān)鍵詞:機(jī)械手;PLC;步進(jìn)電機(jī)中圖分類號(hào):TP241 文獻(xiàn)標(biāo)志碼:A 文章編號(hào):Design of the Control System of 4dimension Motordriven Mechanical Manipulator Based on PLCAbstract: Motordriven mechanical manipulator disscussed in this paper consists of poweroperated mechanical manipulator,yaxis and zaxis screw lever modules ,rotatry mechanism of manipulator,rotatedplate at the bottom etc. On the control of PLC system,it can take bodies from one place to another in the range of its journey. It can be placed on different manufacture assembly lines or goods circulation lines. Key Words:mechanical manipulator。 PLC。 step motor隨著微電子技術(shù)、計(jì)算機(jī)和現(xiàn)代控制理論的不斷完善,機(jī)械手技術(shù)也快速發(fā)展。按實(shí)現(xiàn)功能和驅(qū)動(dòng)方式劃分,機(jī)械手可以分為很多種。僅就驅(qū)動(dòng)方式,就有氣動(dòng)(或液動(dòng))、電動(dòng)和電氣混合等。為實(shí)現(xiàn)不同的功能,有3個(gè)自由度的,也有5個(gè)自由度的,甚至還有6個(gè)自由度的。本文中,筆者僅論述基于PLC技術(shù)的4個(gè)自由度電動(dòng)機(jī)械手的控制設(shè)計(jì),它能滿足絕大多數(shù)場(chǎng)合的搬運(yùn)需要,并且可用于教學(xué)實(shí)驗(yàn),具有良好的示范性和教學(xué)性。1 4
