機械式光開關自動化組裝系統之研製
Development of an automatic assembly system for mechanical optical switches
摘要
目前許多機械式光開關及其它光學元件的組裝仍須仰賴大量的人力,不僅耗時且效率低。在本論文中,我們主要致力於機械式光開關之研究與自動化組裝技術。本研究整合了光、機、電各領域的技術,且已經成功地開發出機械式光開關的自動化組裝系統。系統中使用CCD及影像處理的技術來協助裝置於四軸平台上的夾爪抓取輸出housing模組,並利用IR card來執行粗對光的程序。精對光的部份則是結合了電控平台、尋光演算法及光功率計來完成。最後利用UV膠及UV光源將輸出及輸入模組封裝在一起,完成整個機械式光開關的組裝程序。 實驗的結果顯示,我們所組裝的光開關可以成功通過Bellcore的光開關國際規範。另外,相較於人工組裝的程序,我們所開發的自動化組裝系統不僅可以大量的縮短組裝時間且可以提高光開關插入損失的穩定性。

Currently, there are many mechanical optical switches still assembled manually, which accounts for the high price of optical switch due to the low throughput and time consuming of the assembly process. In this paper, we engage in the research of mechanical optical switch and its automatic assembly system techniques. We have successfully developed an automatic assembly system for mechanical optical switch. In this system, we use CCD and image process to assist the gripper which was mounted on the 4-axis micro stage in catching the output housing module and then implement the coarse alignment process by taking advantage of IR card that can show the invisible light spot on it. The fine alignment process is carried out by combination of optical light searching algorithm, motorized micro stage and power meter. Finally, we use UV light and UV glue to package output and input modules together to finish the processes of assembly of mechanical optical switch. Experimental results showed that our optical switches can meet the international specification called Bellcore for optical switch and the developed automatic assembly system can not only largely reduce the assembly time but also enhance the stability of insertion loss of optical switch in comparison with those assembled by human.
