本研究主要發展智能化滑塊，將感測器內嵌於線性滑軌之循環式滾珠滑塊中，此滾珠滑塊中安裝兩種感測器，第一個為提供定位訊息的光學位置傳感器，第二個為觸覺式秤重傳感器，稱為薄膜式壓力傳感器(Force Sensitive Resistor, FSR)，也稱為力敏電阻，此感測器量測來自導軌的力量，利用這兩種感測器檢測滾珠滑塊在線軌上的位置以及線軌變形造成的受力變化，甚至是量測單一線軌直線度、雙線軌相對不平行度、螺帽受力以及計算軸承受力與壽命。結果顯示，單線軌直度量測實驗中智能滑塊與數位千分錶所量測之直度分別小於50Nt與4μm，而雙線軌相對平行度量測實驗中不平行度6條、5條、2條以及1條之智能滑塊與數位千分錶量測數據之間的相關係數皆大於0.5。工具機作動過程是以馬達驅動螺桿帶動工作平台於線軌上進行軸向運動，因此本研究運用相對偏移量的概念發展單一線軌直線度與雙線軌相對不平行度，以及應用靜力學取得螺帽受力與軸承受力，進而獲得軸承工作壽命，此檢測發展系統分別針對工作平台組裝前後進行量測，當無法利用馬達編碼器取得平台位置訊號時，可透過智能滑塊中的位置感測器偵測平台於線軌上的位置。實驗架構為使用數位千分錶量測線軌狀況，利用力量感測器量測線軌變形造成的受力變化，以及使用3D印表機印製的夾具夾持位置感測器。本研究發展的檢測系統可幫助調整及組裝線軌，甚至是工具機系統即時監測導軌平行度、螺帽負載變化、及軸承壽命。 A cost-effective sensor-embedded smart linear guideway type (LGT) recirculating linear ball bearing, or simply called carriage hereafter, is proposed. Two kinds of sensors are installed on this smart carriage. The first one is an optical mouse sensor which provides the positioning information. The second one is a tactile load cell, called film type pressure sensor, also known as Force Sensitive Resistor (FSR), which measures the forces from the guideway. These two sensors are utilized to monitor the position of the carriage on the linear guideway and the loading change caused by the deformation of linear guideway. By tracking the force variation sensed by the FSR along the guide way, the linear guideway straightness and parallelism between the two linear guideways can be determined indirectly. Results show that the differences in measuring the straightness of reference guideway between the proposed this smart carriage system and dial gauge are less than 50Nt and 4μm, respectively. Results also show that the correlation coefficients in measuring the parallelism of the two linear guideways are more than 0.5. Moreover, the force acting on the screw nut as well as the supported bearing at two ends can be determined when the worktable is traveling, which enables us to calculate the remaining useful life (RUL) of nut and bearings. A ball screw feed drive system with adjustable linear guideways was built to assess the performance of the proposed smart carriage both in its positioning accuracy and the on-line measurement of linear guideway straightness and parallelism as compared to those measured by the optical ruler and dial gauge, respectively.
