本論文研究是設計一LED點測單元,取代目前在自動化機械中所使用的槓桿式之彈簧檢知機構。目前使用之點測裝置的克重精度極差,若以人員調整模式誤差達80%以上,無法滿足高精度的需求,故本研究擬以自動回授控制設計取代人力調整。 本文以LED產業之點測設備之功能為範例,探討所設計的點測裝置,內容包括應變規的選用、機構設計的環境,經由ANSYS模擬分析、及實驗測試,以及利用線性迴歸方法解析實驗數據,找出輸入力與輸出電壓之間最佳之線性關係。經實際運用檢測之結果,可將誤差大幅降低達到初期預設目標之10%以下誤差之精度。
In this study, a LED spot measurement unit is designed to replace the conventional unit using lever-type spring inspection mechanism. Weight precision Accuracy of the current measurement unit is not qualified. Pattern error reaches up to 80% while adjusting by labor work so that cannot satisfy the requirement of high precision. Therefore, it is proposed to utilize automatic measurement and feedback control method to enhance the accuracy. This article takes probing equipment function of LED industry as an example to discuss designed probing device. It consists of strain gauge selection, mechanism design environment, simulation analysis via ANSYS, experimental test and using linear regression to analyze experimental data to find linear relationship between input force and output voltage. To apply the inspected result practically, the error can be decreased significantly for reaching below 10% precision of initial stage default target.
