  • 本論文目標為設計一Delta構型之機器手臂機構,亦稱為三軸平行並聯機構,並以此機構達成在X、Y、Z三方向運動之功能。在此Delta機器手臂機構設計過程中,先以最大桿長所構成之半球,在其空間內進行取點後再進行逆轉換,以求得合適之轉動角並以此來進行其工作空間之分析,之後再改變上、下桿之參數以分析此參數對整個工作空間之影響,最後在分析工作空間完成後選擇最佳尺寸以進行機構設計並實現。
    在本論文中,特別對此機構之平行四連桿接頭部分進行創作設計,此新設計之球軸承,由側邊之一半球面及對立邊之二局部球面所構成,此三球面藉由彈簧供給氣栓之預力而使球頭套貼於球面上,與以往所設計不同之處為當所承受之重量大於允許值時,四連桿也不會造成脫落之現象,並能確保球頭能貼附在球面上保持其構型之完整性。為驅動由此設計製造之Delta構型機器手臂,在既有之三軸CNC工具機控制器軟體中增加機構正、逆轉換計算程式,並將此Delta構型機械手臂機構與三軸CNC工具機控制器相結合成功達到X、Y、Z三方向之驅動,最後對此機構之運動進行驗證。
