摘要

本篇論文研究主要目的是探討使用可程式控制器(PLC)進行雷射機台的安全程序控制的可行性分析。近年來因雷射用於加工設備市場需求逐年成長，而雷射光強大的能量帶來了加工製程上的方便，相對的也因其特性進而對人體某些部位如易產生傷害，主要會對眼精的視網膜及皮膚傷害，因此必需對雷射機台採取一些適當的控制及防護措施，確保設備運作時對設備操作人員及設備的安全。
本論文主題為可程式程序控制實現雷射機台的安全防護機制，探討設備操作人員和設備的安全。實驗設備使用KEYENCE PLC為控制系統，其CPU模組作為雷射機台的安全程序控制與軸控控制，配合溫控模組作為機台溫度即時監控，AD模組作為機台工作電壓的即時監控，I/O模組作為訊號燈及警報器控制，配合兩軸XY運動平台，整合模擬成雷射機台安全防護控制系統，探討雷射機台的安全防護機制。
此研究經實驗證明PLC從監控到設備異常點到完成輸出反應可在兩個掃瞄時間內完成，相較於PC Based會因其系統的負載 而變更程式運算時間而言相對的快速與穩定。可對雷射周邊進行即時監控，進而達到雷射機台的設備安全防護。希望藉由此研究能讓雷射自動化設備廠等瞭解雷射在加工設備上可能帶來的危害，使能其能夠建立正確的雷射加工設備的安全及防護觀念。

Main purpose of this thesis is to investigate the use of a programmable controller (PLC) for laser safety program control machine Feasibility Analysis. Laser processing equipment used in recent years because of the market demand growing year by year, while the powerful energy laser machining process brings the convenience, but also because of the relative characteristics of certain parts of the human body and thus prone to injury as the main be eye refinement of the retina and skin damage, so necessary for the laser machine to take some appropriate control and protective measures to ensure the operation of the device when the equipment operator and equipment safety.
This thesis is programmable process control laser machine to achieve security protection mechanisms, explore the equipment operator and equipment safety. Using KEYENCE PLC laboratory equipment for the control system, the CPU module as laser machine control and safety procedures axis control control, with temperature control module as machine temperature real-time monitoring, AD module machine operating voltage as real-time monitoring , I/O modules as signal lights and siren control, with two-axis XY motion platform to integrate simulation into the laser machine safety control system, explore the laser machine's security mechanisms.
The experiment proved that this study PLC outliers from the monitoring to the device to complete the output reaction can be completed within two scan time, compared to PC Based on the load of the system will change its program in terms of computation time is relatively quick and stability. Surrounding the laser can be real-time monitoring, thus achieving the laser machine equipment safety. I hope through this study to make laser factory automation equipment such as laser machining equipment to understand the potential hazards to enable it to establish the correct laser processing equipment, safety and protection concepts.
