Embodiment Construction

[0025] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0026] Referring to Figure 1, a negative pressure-assisted bionic dry adhesion pick-up structure is a sucker-shaped elastic body 1 as a whole. The size of the elastic body 1 is on the order of millimeters to centimeters, and a layer of imitation gecko mushroom is bonded on the surface of the elastic body 1. The size of a single gecko-like dry-adhesive elastic body structure 2 is at the micron level.

[0027] The elastic body 1 and the gecko-like mushroom-like dry adhesive elastic body structure 2 are all made of silicon rubber or polyurethane.

[0028] refer to diagram 2-1 , Figure 2-2 , when the roughness of the surface 11 of the object is at the micron level, such as the surface of ground glass and gallium nitride, since the scale of the gecko-like mushroom-like dry-adhesive elastomer structure 2 is in the same order of magnitude, the adhesion effect is not obv...

Abstract

The invention discloses a biomimetic dry-adhesion pickup structure with negative pressure assistance and a preparation technology. The structure is overall an elastic body being in a suction cup shape. A layer of a dry-adhesion elastic body structure in a gecko-like mushroom shape is attached to the surface of the elastic body. According to the preparation technology, the elastic body in a suctioncup shape is prepared firstly, then the dry-adhesion elastic body structure in a gecko-like mushroom shape is prepared, and finally a composite structure is prepared. Adhesive pickup of coarse surfaces of any material in any size is achieved, and the requirements for mechanical pickup and production line transport can be met.

Description

technical field [0001] The invention belongs to the technical field of bionic manufacturing of micro-nano engineering, and in particular relates to a negative-pressure-assisted bionic dry adhesion pick-up structure and a preparation process. Background technique [0002] The transfer and transportation of rough surfaces at nano-, micro-, and nano-scales is a key problem that needs to be solved in mechanical grasping, production line demonstration applications, and other occasions. At present, the main ways to achieve this goal are through mechanical clamping, vacuum chucks, electromagnetic chucks, and electrostatic chucks. Or conductive, etc., limiting the types of rough surfaces that can be gripped. Since Professor Autumn and others clarified the adhesion mechanism of gecko feet on Nature in 2000, the bionic micro-nano adhesion structure of gecko has received extensive attention and research, and has been gradually applied to adhesion-pickup-transfer occasions, such as Tsi...
