Description

technical field [0001] The invention relates to the technical field of adsorption devices, in particular to a permanent magnet adsorption wheel used on a magnetically permeable wall surface that can realize rapid demagnetization. Background technique [0002] With the continuous advancement of globalization, the demand for large-scale manufacturing of large-scale components such as large ships and heavy machinery continues to increase. The manufacture of these large-scale components often requires welding to achieve, and there may be defects in the welding, which will seriously affect the quality of components. It even brings security problems. In traditional weld inspection, workers need to wear masks and use inspection instruments to carry out inspection operations. The working environment is poor and the risk is relatively high. Therefore, the digital fluorescent magnetic particle inspection robot used for non-destructive inspection of magnetic wall surfaces has a wide ra...

Problems solved by technology

Most permanent magnet wall-climbing detection robots on the market use fixed magnetic force, that is, no matter what the wall environment is, the adsorption force generated by the magnet module is basically fixed. Although this method is more reliable in safety, the performance of the magnet module is poor, and the magnetism of the magnet cannot be controlled. Fully utilized; the provided magnetic force cannot be adjusted, which reduces the motion performance of the robot; it is inconvenient to demagnetize the magnet, and it is difficult for the wall-climbing robot to detach from the magnetically conductive wall surface
