The invention provides a laser-based wireless closed-loop control method and device for restraining medium-thickness plate welding deformation and a storage medium. The method includes the steps thatlaser light is emitted; the emitted valid laser light is received; the received valid laser light is processed, the deformation amount of a medium-thickness plate is obtained, and an output parameteris determined; and the determined output parameter is received, and the deformation amount of the medium-thickness plate is adjusted according to the output parameter. By means of the laser emitting and receiving technology, the welding deformation amount of the medium-thickness plate is monitored in real time, monitored data are transmitted to a mechanical hand control cabinet in a wireless manner, the mechanical hand control cabinet analyzes the monitored data, then welding deformation is restrained by adjusting the swinging manner of mechanical hand welding, the electric current magnitude and other parameters, closed-loop control is formed, and welding deformation is restrained fundamentally. Meanwhile, interference and influences caused by cables to mechanical hand actual welding are avoided.

Description

technical field [0001] The present invention relates to the field of welding technology, in particular to a wireless closed-loop control method, device and storage medium for suppressing welding deformation of medium and thick plates based on laser. Background technique [0002] With the advancement of science and technology and the development of industry, various welding machines and welding methods are changing with each passing day. However, in the construction process, because the weldment is a whole, if the weldment is partially heated and cooled during the welding process, The degree of thermal expansion and contraction of the metal at each part of the welded joint is also different. The overall factor of the weldment determines that all parts are interconnected and restricted, and cannot be freely elongated and shortened, so strain and deformation will inevitably occur during the welding process. Due to the internal stress generated during the welding process, the w...

AI Technical Summary

Problems solved by technology

Due to the internal stress generated during the welding process, the weldment is deformed, which seriously affects the project quality, project progress and welding performance; however, the way of mechanical pressure to suppress welding deformation is cumbersome and inflexible, and different products require different fixtures , the economic investment is large, and the effect is sometimes not obvious, and the cause of the welding deformation has not been found out fundamentally, and the welding deformation has not been solved

At the same time, the existing methods of mechanical pressure to suppress welding deformation all require cable connection. In the actual manufacturing process, the cable will affect the welding of the manipulator.
