Adsorption cavity with honeycomb grid structure and adsorption method thereof

Abstract

The invention discloses an adsorption cavity with a honeycomb grid structure and an adsorption method thereof, and belongs to the technical field of robots. The adsorption cavity comprises a fan, a hose, an air cylinder, a negative pressure adsorption side wall and a connecting plate, wherein a negative pressure adsorption cavity body internally provided with a cavity is formed by the connecting plate and the negative pressure adsorption side wall, the lower surface of the negative pressure adsorption side wall is tightly attached to an adsorbed surface by downwards pressing the connecting plate through the air cylinder, air is continuously pumped through the fan, a negative pressure adsorption area is formed by utilizing the venturi effect of the lower surface of the negative pressure adsorption side wall and the adsorbed surface, so that the negative pressure adsorption cavity is stably and reliably adsorbed to the adsorbed surface. The invention further provides a corresponding adsorption method. The structure can actively conform to complex curved surfaces, attaching between the adsorption cavity and a free curved surface can be ensured, so that the structure can adapt to variable-curvature surfaces of various materials, so that a wall climbing robot can be guaranteed to still keep stable and reliable adsorption on the variable-curvature surfaces under the moving state, andthe low resistance during movement is ensured.

Description

technical field [0001] The invention belongs to the technical field of robots, and more specifically relates to an adsorption cavity with a honeycomb grid structure and an adsorption method thereof. Background technique [0002] In the field of mobile robot research, the wall-climbing robot is an important branch. It combines adsorption technology, mobile technology and control technology well, can be adsorbed on curved surfaces for local special processing operations, and can grind large structural parts. Throwing and other processing. Adsorption is a unique function of the wall-climbing robot, and it is also a significant difference from ordinary mobile robots. At present, there are mainly the following adsorption methods: negative pressure adsorption, magnetic adsorption, thrust adsorption and biomimetic adsorption (based on intermolecular van der Waals force). In comparison, vacuum adsorption has no strict requirements on the material of the adsorption surface, and can...
