在現代工業中,為了精準的控制機械輸出,力與扭力的監控就扮演著相當重要的角色。然而目前的市面上的力量、扭力感測器,其量測系統架構皆是:應變規連接而成的惠斯通電橋並將量測訊號輸出至訊號放大器,在此架構下有兩個主要的問題:第一,應變規的安裝,應變規需黏貼在待測系統上,黏貼的品質對於量測的結果有相當的影響;第二,應變規組成惠斯通電橋所需的佈線限制系統設計的彈性。
本論文提出一種新型的感測器設計理念成功解決了傳統上以應變規來設計的問題:利用印刷電路板 (PCB) 上既有的銅箔設計出可以對應受力方向的圖型並將惠斯通電橋、訊號放大器一同設計在PCB上。此種設計改善原本的量測系統:不需要黏貼應變規於待測系統上並將導線從原本的系統架構移除,在量測時可將導線擾動或訊號傳輸時產生的干擾消除並增加整體感測系統設計上的彈性。本研究之研究結果可達到的量測範圍為28 Nm 以及解析度為60 mNm 與16.67 k-count/Nm 的敏感度。
In modern industry, the monitoring force and torque is an important mission to control the output of machine. However, the measurement system of commercial torque and force sensor is built by wheatstone bridge connected by strain gauges and output to instrumentation amplifier. There are two problems in this system. The first problem is mounting strain gauges. Strain gauges have to mount on system under test. The quality of mounting strain gauges influences the results of measurement very much. The second problem is the flexibility of system design is limited by the wiring of wheatstone bridge connected by strain gauges.
The research proposes a novel idea of sensor design to solve the problem of mounting strain gauges. The copper on Printed Circuit Broad (PCB) is used to design the sensing pattern which is able to correspond the direction of applied force. The designed PCB consisted of the sensing pattern, wheatstone bridge and instrumentation amplifier. This proposed design improves traditional measurement system without mounting strain gauges and removing wires from the measurement system. With reducing the influence of signal transmission and wire disturbance in measurement, the flexibility in system design can be improve. The PCB torque sensor can measure 28 Nm with resolution 60 mNm and sensitivity 16.67 k-count/Nm.
