Problems solved by technology

However, magnetic adsorption is very sensitive to changes in the adsorption gap. When the gap becomes larger, the adsorption force drops rapidly, causing the robot to fall from the working wall.

Embodiment Construction

[0009] The present invention will be further described below in conjunction with accompanying drawing.

[0010] Such as figure 1 As shown, the present invention includes a first magnetic yoke iron 1, a first magnetic absorption block 2, a magnetic isolation block 3, a second adsorption magnetic block 4, and a magnetic isolation under the first magnetic block 2 arranged under the magnetic yoke iron. The second magnetic yoke iron 5 on the left side of the block 3, the third magnetic yoke iron 6 on the right side of the magnetic isolation block 3 under the second magnetic block 4, etc. are composed of an adsorption unit, a flexible magnetic conduction medium 7 and a workpiece 8; the adsorption unit , the flexible magnetically permeable medium 7 and the workpiece 8 form a magnetic circuit 9 . When the distance between the adsorption unit and the workpiece 8 changes, the flexible magnetically permeable medium 7 can always keep in contact with the two, and the magnetic permeability...

Abstract

The invention relates to a flexible magnetic adhesion method for movable welding robot. An adhesion device comprises a first magnetic conduction yoke, a first magnetic block, a magnetic isolation block, a second magnetic block, a second magnetic conduction yoke, a third magnetic conduction yoke, and a flexible magnetic conduction medium, wherein the first magnetic conduction yoke, the first magnetic block, the magnetic isolation block, the second magnetic block, the second magnetic conduction yoke, and the third magnetic conduction yoke and the like form an adhesion unit. The method is characterized in that the flexible magnetic conduction medium is added between the adhesion unit and a work piece, so that the adhesion unit, the flexible magnetic conduction medium and the work piece form a magnetic circuit; and when the distance between the adhesion unit and the work piece changes, the flexible magnetic conduction medium is always tightly contacted with the adhesion unit and the work piece to maintain the magnetic circuit. The invention has the advantages of simple structure, and easiness in implementation; since the flexible magnetic conduction medium with the magnetic permeability far beyond the air is added between the adhesion unit and the work piece, when the distance between the adhesion unit and the work piece changes, the flexible magnetic conduction medium is always contacted with the adhesion unit and the work piece and the change of the magnetic permeability is extremely small, and when the clearance between the adhesion unit and the work piece changes, the adhesion force changes very slightly.

Description

technical field [0001] The invention relates to the technical field of robots, in particular to a flexible magnetic adsorption method for a mobile welding robot on an uneven steel surface. Background technique [0002] The development of modern industry and manufacturing technology has led to more and more applications of important large-scale structural parts. The welding, testing and maintenance of such components must be done on-site. To realize automatic welding, testing and maintenance, mobile The robot as a work platform is the key to realization. The automatic welding of large components requires that the robot can work on the wall, so how to attach the mobile welding robot to the surface of the workpiece has become the primary problem to be solved by the mobile welding robot. Due to its compact structure and reliable adsorption, magnetic adsorption has become the main adsorption method for mobile welding robots. However, magnetic adsorption is very sensitive to cha...
