Abstract

The invention discloses a miniature grabbing device based on van der waals force and a grabbing method of the miniature grabbing device. The miniature grabbing device comprises a supporting and fixingframe, a bionic adhesive material and a sticking and desorption control system. The supporting and fixing frame comprises a bottom plate and longitudinal vertical plates arranged at two sides of thebottom plate. One side of the bionic adhesive material is mounted at the lower end of the longitudinal vertical plate, and the other side of the bionic adhesive material is a free end and can rotate along the side, mounted on the longitudinal vertical plate, of the bionic adhesive material. The sticking and desorption control system comprises a pressure device located above the bionic adhesive material and a tearing device connected with the free end of the bionic adhesive material. The bionic adhesive material is pressed down by the pressure device to adhere to the surface of a pre-grabbed object and is transferred to a predetermined position and then torn off along one side of the free end by the tearing device so as to be separated from the grabbed object. The device is mainly used forclamping, carrying and unloading a target object in the industry and capturing the target object in a space environment.

Description

technical field [0001] The invention relates to a van der Waals force-based miniature grasping device and a grasping method thereof, belonging to the field of adhesion mechanisms. Background technique [0002] The mechanism by which geckos can stably adhere to various surfaces is derived from van der Waals force, and this mechanism benefits from hundreds of thousands of micronano bristles on the soles of their feet. Based on the bionic material and structure of the gecko mechanism and structure, the micro-clamping device is designed. Because it has wide adaptability to surfaces with different roughness and is not limited by the space environment, it has a wide range of application values. Objects are clamped, transported and unloaded, and target objects can be captured in the space environment, assisting astronauts to work or fix positions, so as to grab and transport different objects safely, conveniently and efficiently. [0003] The existing relevant practical equipment ...
