現今工業機器人主要分兩大類——直角坐標機器人和關節機器人，這兩類機器人在諸多工業


領域得以廣泛應用。MOTEC(中國)營業體系多年從事工業機器人研發和制造，本文是我們研發


設計隊伍結合的多年經驗和積累來介紹一下直角坐標機器人特點和應用，以及直角坐標工業


機器人的后期保養和維護。
直角坐標機器人
1、概念：
我們現在所講的工業機器人和直角坐標機器人是指以標準化結構件為機械本體，內嵌方軌或


圓柱導軌為支撐導向，以皮帶傳動或絲桿傳動為主要機械傳動方式，配合使用伺服電機步進


電機和多軸運動控制系統一起構成工業化的重復使用的機器人系統。在現在機器人系統中，


也必須結合機器人使用過程中的工藝特點來選用相符合的機器人手抓和傳感器。
因為直角坐標的結構，它的承載主要指標受到標準化結構件為機械本體和內嵌方軌或圓柱導


軌承載能力限制。一般這類機器人，比相應特制的鋼結構的機器人承載能力要小，但容易批


量化生產，容易模塊化管理，有效的控制了成本保證了精度和品質得一致性，為眾多行業所


使用。
工業機器人能夠搬運物體、操作工具，以完成各種作業。
2、特點：
1）任意組合成各種樣式，形成兩軸到六軸不同結構形式。
   以為是結構化標準件的機械本體，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，直角坐標機器人的系統精度是不同的。
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)的機器人研發生產隊伍目前在中國最長的單根機器人運行產度為20多米。已


在用戶處成功使用。
3）負載能力強：通常是到200公斤，但當采用多根多滑塊結構時其負載能力可增加到數噸。
   當你的負載要求較大時，就要和MOTEC(中國)的機器人研發工程師及行溝通，在設計中用


輔助結構或者改變其本體承載能力才可以。
4）高動態特性：輕負載時其{zg}運行速度每秒8米，加速度每秒5米。
5）高精度：重復定位精度可達到0.05mm～0.01mm。
6）擴展能力強：可以方便改變結構或通過編程來適合新的應用。
7）簡單經濟：編程簡單類同數控銑床，易培訓員工和維修，使其具有非常好的經濟性。
8）壽命長：直角坐標機器人的壽命一般是10年以上，維護好可達40年。
   關于機器人的壽命，必須要提及維護問題。一般機器人維護，主要是指機器人本體的維護


。和維護機床是一樣的，要定期上油和清潔，需要檢查和緊固。
關于機器人的定義隨著科技的不斷發展，在不斷的完善，直角坐標機器人作為機器人的一種


，其含義也在不斷的完善中。
直角坐標機器人應用范圍廣：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、上下料、包裝、碼垛、檢測、探傷、分類、裝配、貼標、噴碼

、打碼和噴涂等任務。
