Abstract

The invention discloses an adhesion and desorption control device which comprises a base, an actuator and a movement mechanism, wherein the actuator is mounted on the base; the movement mechanism comprises a bearing unit, a stripping unit and an adhesion unit; the bearing unit is compressible but tensile, and the upper surface of the bearing unit is fixed to the lower surface of the base; the stripping unit is a thin plate with high elasticity modulus and is provided with a first side and a second side which are opposite to each other; the upper surface of the stripping unit is fixed to the lower surface of the bearing unit; the actuator is fixed to the first side of the stripping unit; the adhesion unit is arranged on the lower surface of the stripping unit; the stripping unit is bent andelastically deformed from the first side to the second side under the action of the actuator, so that the adhesion unit synchronously moves to realize desorption release; and the stripping unit is ina plane state after elastic deformation is recovered so as to realize adhesion grabbing. The control device can achieve rapid, reliable and stable high-strength adhesion and desorption control, and is low in cost, simple in structure, convenient to operate and good in repeatability.

Description

technical field [0001] The invention relates to the field of mechanical structures and components, in particular to a control device for adhesion and detachment. Background technique [0002] The active regulation of adhesion and friction can help various advanced intelligent mechanical equipment components such as manipulators and robot feet to complete operations such as grasping, assembling, docking, and movement between surfaces under various environmental conditions. Inspired by creatures such as geckos and beetles, researchers revealed the mechanical mechanism of biomimetic adhesion, and based on this, prepared biomimetic adhesion surfaces with high-strength adhesion and friction properties. Compared with the traditional grasping method that relies on mechanical pressure and friction, the bionic adhesion technology based on van der Waals force has the advantages of flexible contact, can be used in vacuum environment, small stress concentration, no pollution, simple con...
