摘要： Disclosed are an automatic welding system and method for large structural parts based on hybrid robots and 3D vision. The system comprises a hybrid robot system composed of a mobile robot and an MDOF robot, a 3D vision system, and a welding system used for welding. The rough positioning technique based on a mobile platform and the accurate recognition and positioning technique based on high-accuracy 3D vision are combined, so the working range of the MDOF robot in the XYZ directions is expanded, and flexible welding of large structural parts is realized. The invention adopts 3D vision, thus having better error tolerance and lower requirements for the machining accuracy of workpieces, positioning accuracy of mobile robots and placement accuracy of the workpieces; and the cost is reduced, the flexibility is improved, the working range is expanded, labor is saved, production efficiency is improved, and welding quality is improved.

摘要： Disclosed are an electrostatically driven comb structure of an MEMS (Micro Electro Mechanical System), a micro-mirror using the same, and a preparation method therefor. The surface of a comb of the electrostatically driven comb structure of the MEMS has an insulating layer, and the insulating layers on the surfaces of adjacent combs are the same type of insulating layers or different insulating layers; the micro-mirror with the electrostatically driven comb structure of the MEMS successively includes a substrate, an isolating layer and a device layer from bottom to top; the method for manufacturing the micro-mirror prepares the insulating layers by high temperature oxidization, plasma enhanced chemical vapor deposition, low pressure chemical vapor deposition, atmospheric pressure chemical vapor deposition, physical deposition, atomic layer deposition or stepwise heterogeneous deposition; same or different insulating layers are obtained on the surfaces of the driving comb and the ground comb; when the driving comb and the ground comb adsorb each other, the insulating layers on the surfaces of the two contact without forming a short circuit, so that a good insulating effect is achieved. The electrostatically driven MEMS micro-mirror capable of preventing adsorptive damage provided by the present invention features compact structure and simple process.
