現(xiàn)今工業(yè)機(jī)器人主要分兩大類——直角坐標(biāo)機(jī)器人和關(guān)節(jié)機(jī)器人，這兩類機(jī)器人在諸多工業(yè)
領(lǐng)域得以廣泛應(yīng)用。MOTEC(中國)營業(yè)體系多年從事工業(yè)機(jī)器人研發(fā)和制造，本文是我們研發(fā)
設(shè)計隊伍結(jié)合的多年經(jīng)驗和積累來介紹一下直角坐標(biāo)機(jī)器人特點和應(yīng)用，以及直角坐標(biāo)工業(yè)
機(jī)器人的后期保養(yǎng)和維護(hù)。
直角坐標(biāo)機(jī)器人
1、概念：
我們現(xiàn)在所講的工業(yè)機(jī)器人和直角坐標(biāo)機(jī)器人是指以標(biāo)準(zhǔn)化結(jié)構(gòu)件為機(jī)械本體，內(nèi)嵌方軌或
圓柱導(dǎo)軌為支撐導(dǎo)向，以皮帶傳動或絲桿傳動為主要機(jī)械傳動方式，配合使用伺服電機(jī)步進(jìn)
電機(jī)和多軸運(yùn)動控制系統(tǒng)一起構(gòu)成工業(yè)化的重復(fù)使用的機(jī)器人系統(tǒng)。在現(xiàn)在機(jī)器人系統(tǒng)中，
也必須結(jié)合機(jī)器人使用過程中的工藝特點來選用相符合的機(jī)器人手抓和傳感器。
因為直角坐標(biāo)的結(jié)構(gòu)，它的承載主要指標(biāo)受到標(biāo)準(zhǔn)化結(jié)構(gòu)件為機(jī)械本體和內(nèi)嵌方軌或圓柱導(dǎo)
軌承載能力限制。一般這類機(jī)器人，比相應(yīng)特制的鋼結(jié)構(gòu)的機(jī)器人承載能力要小，但容易批
量化生產(chǎn)，容易模塊化管理，有效的控制了成本保證了精度和品質(zhì)得一致性，為眾多行業(yè)所
使用。
工業(yè)機(jī)器人能夠搬運(yùn)物體、操作工具，以完成各種作業(yè)。
2、特點：
1）任意組合成各種樣式，形成兩軸到六軸不同結(jié)構(gòu)形式。
以為是結(jié)構(gòu)化標(biāo)準(zhǔn)件的機(jī)械本體，所以它很容易任意裁切組合。我們需要注意的是，各種
組合之后，直角坐標(biāo)機(jī)器人的系統(tǒng)精度是不同的。
2） 超大行程：單根最多長度是6米，但可以多根方便地級連成超大行程，例如50米長。
MOTEC(中國)的機(jī)器人研發(fā)生產(chǎn)隊伍目前在中國最長的單根機(jī)器人運(yùn)行產(chǎn)度為20多米。已
在用戶處成功使用。
3）負(fù)載能力強(qiáng)：通常是到200公斤，但當(dāng)采用多根多滑塊結(jié)構(gòu)時其負(fù)載能力可增加到數(shù)噸。
當(dāng)你的負(fù)載要求較大時，就要和MOTEC(中國)的機(jī)器人研發(fā)工程師及行溝通，在設(shè)計中用
輔助結(jié)構(gòu)或者改變其本體承載能力才可以。
4）高動態(tài)特性：輕負(fù)載時其{zg}運(yùn)行速度每秒8米，加速度每秒5米。
5）高精度：重復(fù)定位精度可達(dá)到0.05mm～0.01mm。
6）擴(kuò)展能力強(qiáng)：可以方便改變結(jié)構(gòu)或通過編程來適合新的應(yīng)用。
7）簡單經(jīng)濟(jì)：編程簡單類同數(shù)控銑床，易培訓(xùn)員工和維修，使其具有非常好的經(jīng)濟(jì)性。
8）壽命長：直角坐標(biāo)機(jī)器人的壽命一般是10年以上，維護(hù)好可達(dá)40年。
關(guān)于機(jī)器人的壽命，必須要提及維護(hù)問題。一般機(jī)器人維護(hù)，主要是指機(jī)器人本體的維護(hù)
。和維護(hù)機(jī)床是一樣的，要定期上油和清潔，需要檢查和緊固。
關(guān)于機(jī)器人的定義隨著科技的不斷發(fā)展，在不斷的完善，直角坐標(biāo)機(jī)器人作為機(jī)器人的一種
，其含義也在不斷的完善中。
直角坐標(biāo)機(jī)器人應(yīng)用范圍廣：可以方便地裝配多種形式和尺寸的手爪，可以勝任許多常見的
工作，如焊接、切割，搬運(yùn)、上下料、包裝、碼垛、檢測、探傷、分類、裝配、貼標(biāo)、噴碼
、打碼和噴涂等任務(wù)。
