    Abstract: 力量的監測是執行智慧製造的重要手段,而在適當位置裝設具靈敏度及強健性的感測器以達成監測的目的更是智慧製造的關鍵。滾珠螺桿是機械設備中的基本元件。本研究以自行設計的力量感測器裝設在滾珠螺桿中的相關位置來監測滾珠螺桿在長時間使用中的剛性變化及裝設之平行度是否妥適,以展示力量感測器的設計及裝設位置在監測端可以發揮的作用及重要性。先前研究團隊開發之預壓力感測器可以成功用來監測預壓力,但使用的可靠度需要檢測。測試自行開發預壓力感測器之可靠度方面是使用垂直軸測試平台來進行滾珠螺桿的加速磨耗實驗,其中一支小螺桿是使用本研究團隊研發之低摩擦高耐磨鍍層,除了驗證預壓力感測器可靠度外,也探討高耐磨鍍層對滾珠螺桿運轉之效益。在螺桿平行度的監測上,是使用與預壓力監測相同概念的感測器,將預壓力感測器分佈在均衡的座落於螺桿的四個象限時,除了預壓力的監測也可以同時判斷螺桿裝設的平行度之變化。測試平台是線軌的調整端可以進行偏擺度的調整之平行機台。 根據本論文的結果顯示,自行設計的力量感測器與找到裝設的關鍵位置能達到不同工況需求的監測。從加速磨耗實驗結果證實,預壓力感測器量測之可靠度與訊號檢測結果具可信度,且導入的低摩擦高耐磨鍍層能確實降低滾珠螺桿因摩擦磨耗造成的預壓力損失。根據平行度實驗結果證明,因不同工況需求所改良之預壓力感測器,透過在螺桿上的關鍵位置安裝,可藉由預壓力之間的不平衡判斷出機台的不平行,成功用來檢測工作螺桿因組裝不平行造成的影響。本研究驗證自行研發預壓力感測器經過適當的調整能同時監測預壓力與平行度,並展現本研究開發之預壓力感測器,經過自行設計與找到裝設的關鍵位置具有產業應用性。關鍵字:力量感測器、滾珠螺桿、預壓力、力量監測、平行度
    Monitoring of force is an important means of implementing smart manufacturing, and the installation of sensitive and robust sensors in appropriate locations for monitoring purposes is the key to smart manufacturing. Ball screw is the basic element in mechanical equipment.This research , a self-designed force sensor was installed at the relevant position in the ball screw to monitor whether the rigidity change of the ball screw during long-term use and the parallelism of the installation were appropriate, so as to demonstrate the design of the force sensor. The role and importance of the installation location at the monitoring end.The preload sensor developed by the previous research team can be successfully used to monitor the preload, but the durability and reliability of use need to be tested. To test the durability and reliability of self-developed preload sensors, an accelerated wear test was performed using a vertical shaft test platform with a small ball screw, one of the small ball screws is a low-friction, high wear-resistant coating developed by our research team. In addition to verifying the durability of the preload sensor, the benefits of the high wear-resistant coating for ball screw operation are also discussed. In the monitoring of the parallelism of the ball screw, a sensor with the same concept as the preload monitoring is used. When the preload sensors are distributed in a balanced position in the four quadrants of the screw, in addition to the monitoring of the preload, it is also possible to judge simultaneously. Changes in the degree of parallelism of the ball screw mounting. The test platform is a parallel machine that can adjust the deflection of the slave side of the linear slide.According to the results of this research, self-designed force sensors and key locations for installation can achieve monitoring of different operating conditions. From the results of accelerated wear test, it was confirmed that the durability and signal detection results measured by the preload sensor were reliable, and the low-friction high wear-resistant coating introduced could actually reduce the preload loss due to friction wear of the ball screw. According to the results of the parallelism test, it is proved that the preload sensors modified according to the requirements of different working conditions can be judged to be non-parallel by using the imbalance between the preload through installation at the key position on the screw. To detect the effect of the yaw of the work ball screw due to parallelism. This research verifies that the self-developed preload sensor can monitor preload and parallelism at the same time through appropriate adjustments, and demonstrates the preload sensor developed in this research. It is an excellent industry to design and find key locations for installation universality.Keywords: force sensor, ball screw, preload, force monitoring, parallelism
