A Predictive Maintenance Method for Electron Beam Welding Equipment Based on Edge Computing

Abstract

The embodiment of the present invention relates to the field of electronic equipment, and discloses a method for predictive maintenance of electron beam welding equipment based on edge computing. In the present invention, the first business flow data generated by the electron beam welding equipment performing this welding task is collected by the edge computing device, and the first business flow data includes: welding process data and welded workpiece quality information; the first business flow The data is predicted by the cathode loss prediction model, and the cathode loss of the electron beam welding equipment is obtained by the end of this welding task; the cathode component reserve strategy that matches the cathode loss of the electron beam welding equipment is determined, so as to ensure the cathode loss of the production enterprise Component storage and procurement give guidance to avoid economic losses.

Description

technical field [0001] Embodiments of the present invention relate to the field of electronic equipment, and in particular, to an edge computing-based predictive maintenance method for electron beam welding equipment. Background technique [0002] Electron beam welding has the advantages of high energy density, small heating area, deep electron beam penetration, fast welding speed, narrow heat affected zone of weld seam, small workpiece deformation, convenient electron beam control, and no pollution in vacuum electron beam welding. At present, electron beam welding has been widely used in automobile, aviation, aerospace, nuclear industry and other industries, and has developed into petroleum, chemical, machinery, instrumentation, precision machining and other industries.

Problems solved by technology

[0003] The cathode component of the electron beam welding equipment, whose function is to emit electron beams, is a vulnerable part. When the cathode reaches the life limit, it will cause fluctuations in the electron beam current, which will have a serious impact on the welding quality and welding efficiency; at the same time, the cathode Components are the main accessories of electron beam welding equipment. Because of their procurement cycle and procurement cost, the maintenance cycle of the equipment will be longer, which will reduce the production capacity of the welding unit and affect the on-time delivery of products.

[0004] At present, the vast majority of enterprises that use electron beam welding equipment adopt a passive maintenance strategy on the one hand and an active preventive maintenance strategy on the other hand for the maintenance of the cathode components of the equipment. Both strategies have sudden The risk of failure still cannot be completely eliminated, the maintenance cycle is difficult to control, the use of spare parts resources is unreasonable, and the maintenance cost is relatively high.
