如今，航空航天領域在大型零件上實現精度和剛性的任務，都要由工業機器人來完成。因為飛機計劃的使用期限為10到30年，因此簡單組裝任務的回報可能非常有益。接下來讓我們一起來了解下工業機器人在航空航天領域都有哪些應用。
Nowadays, the task of achieving precision and rigidity on large parts in the field of aerospace must be completed by industrial robots. Since the aircraft is planned to last 10 to 30 years, the payoff from simple assembly tasks can be very beneficial. Next, let\'s learn about the applications of industrial robots in the field of aerospace.
1.鉆孔和緊固Drilling and fastening
這是航空航天工業中使用機器人技術的最大區域。實際上，手動鉆孔需要分三個不同的步驟進行：先導孔鉆孔，最終尺寸鉆孔和鉸孔。此外，手動鉆孔機需要使用大而復雜的夾具，以及功能強大的工具才能在鈦等異質材料中執行這些鉆孔步驟。通過使用工業機器人，無需設計特定的夾具-機器人使用視覺系統在所需位置鉆孔。另外，鉆孔步驟可以單次執行。當人們一次完成工作時，機器人可以節省大量時間。
This is the largest area in the aerospace industry where robotics is used. In fact, manual drilling requires three different steps: pilot hole drilling, final dimension drilling and reaming. In addition, manual drilling machines require large and complex fixtures and powerful tools to perform these drilling steps in heterogeneous materials such as titanium. By using an industrial robot, there is no need to design a specific fixture - the robot uses a vision system to drill holes in the desired location. In addition, drilling steps can be performed in a single run. Robots can save a lot of time when people finish their work at once.
2.檢驗Inspection
任何飛機制造過程中的檢查過程都是至關重要的，并且飛機的檢查要求很高。機器人可以執行多種檢查程序。在某些情況下，末端執行器配有激光掃描儀和測量探針。鉆孔操作后，使用計量設備，然后通過激光掃描儀觀察該孔，該激光掃描儀可以收集不同的信息。
The inspection process in any aircraft manufacturing process is very important, and the aircraft inspection requirements are very high. Robots can perform a variety of inspection procedures. In some cases, the end effector is equipped with a laser scanner and a measuring probe. After the drilling operation, metering equipment is used and the hole is observed through a laser scanner, which can collect different information.
3.焊接Welding
即使復合零件在飛機上越來越受歡迎，金屬零件在某些應用中仍然占有一席之地。實際上，組裝中的金屬零件焊接（例如渦輪機）需要精確進行。在電動機中使用諸如鈦和鎳合金之類的稀有金屬時，工業機器人是必不可少的，以便進行有效而準確的焊接。當談到航空航天應用中的機器人焊接時，可重復性，剛度和嚴格的公差實現是主要論據。
Even though composite parts are becoming more and more popular in aircraft, metal parts still have a place in some applications. In fact, welding of metal parts in assembly (e.g. turbines) requires precision. When rare metals such as titanium and nickel alloys are used in motors, industrial robots are essential for effective and accurate welding. When it comes to robotic welding in aerospace applications, repeatability, stiffness and strict tolerance implementation are the main arguments.
4.密封和分配Sealing and distribution
由于部件的尺寸，對于手動操作者來說，在大型機身或框架部件上施加密封劑，油漆，金屬和陶瓷涂層是困難的。這就是為什么將機器人用于此類應用的原因之一。通過將機械臂放在軌道上，工作單元可以覆蓋30到40英尺的距離，并有幾層樓高。航空航天公司傾向于使用更多的機器人方法，包括從小型到大型點膠應用程序。
Due to the size of the components, it is difficult for manual operators to apply sealer, paint, metal and ceramic coatings on large fuselage or frame components. This is one of the reasons why robots are used in such applications. By placing the robotic arm on the track, the work unit can cover a distance of 30 to 40 feet and be several stories high. Aerospace companies tend to use more robotic methods, from small to large dispensing applications.
5.剛性制造Rigid manufacturing
剛性不是應用程序本身，但是在航空航天制造中使用機器人時，可以認為剛性是一種優勢。實際上，多年來，機器人比以往任何時候都趨向于更加精確。但是，由于具有嚴格的公差，可重復性要求和精確的制造工藝，因此機器人必須更加精確。這就是為什么大多數飛機制造商都使用輔助編碼器的原因。換句話說，他們不信任機器人關節中的原始編碼器。植入機器人后，集成商會安裝輔助編碼器，以準確知道機器人關節的位置。
Rigidity is not the application itself, but rigidity can be considered an advantage when robots are used in aerospace manufacturing. In fact, over the years, robots have tended to be more accurate than ever before. However, due to strict tolerances, repeatability requirements and precise manufacturing processes, robots must be more accurate. This is why most aircraft manufacturers use auxiliary encoders. In other words, they don\'t trust the original encoder in the robot\'s joints. After the robot is implanted, the integrator will install an auxiliary encoder to accurately know the position of the robot joint.
航空航天領域對于設備的制造以及檢測有著非常嚴格的要求，而工業機器人先進的技術應用、制造理念和管理規劃等加速了航天航空領域的發展。
Aerospace industry has very strict requirements for equipment manufacturing and testing, and the advanced technology application, manufacturing concept and management planning of industrial robots accelerate the development of aerospace industry.
