Abstract

The invention discloses a flexible pneumatic finger and a grabbing device. The flexible pneumatic finger comprises a first structural unit, a plurality of second structural units and a third structural unit which are sequentially hinged, wherein the first structural unit, the second structural units and the third structural unit are hinged to form an internal cavity; a latex balloon is arranged inthe internal cavity; and the latex balloon is connected with an air pipe through a vent hole in the first structural unit. The overall structure of the flexible pneumatic finger is more compact; by means of the first structural unit, the second structural units and the third structural unit, a modular design and an application concept can be realized; and the load bearing capacity of the flexiblepneumatic finger is one magnitude order higher than that of a bent flexible soft driver in the same size.

Description

technical field [0001] The invention relates to the field of pneumatic fingers, in particular to a flexible pneumatic finger and a grabbing device. Background technique [0002] Pneumatic fingers in the industry are mainly divided into two categories, one is the rigid pneumatic finger with cylinder piston as the transmission mechanism, which is characterized by linear power output and can withstand large loads. The disadvantage is reflected in the bloated structure of such a mechanical system , not suitable for grasping flexible objects; the other type is flexible pneumatic fingers made of flexible materials such as silica gel and latex as the main body, and imposing special constraints. It is characterized by good grasping surface adaptability, It has no destructive effect on the object to be grasped. The disadvantage is that such a soft material driver usually forms a system with other hard structures to complete the grasping task. Its structure is loose, the output force ...
