Problems solved by technology

However, there are some problems in the use of the existing soft actuators. For example, the soft actuators with long structures will produce many redundant parts when deformed, and when the pressure is too large, the airbags and other parts will be damaged. There will be local expansion and expansion in unnecessary directions. These expansions in unnecessary directions will consume additional gas or liquid source pressure, thereby wasting energy
Moreover, if the cavity wall thickness of the soft actuator is small and the bending degree of the soft actuator is large, the local expansion of the airbag under high pressure may also rupture these local expansion areas, thereby destroying the airtightness and affecting the softness of the soft body. robot lifespan

Abstract

The embodiment of the invention provides a novel flexible finger. The novel flexible finger comprises a finger pulp portion and an air bag portion, wherein the finger pulp portion is used for grabbinga component, the air bag portion is used for inflating and deflating so as to change the bending degree of a finger pulp, the air bag portion comprises a bag face portion and a side edge portion, themaximum section shape of the side edge portion is a rectangular shape lacking a long edge, the finger pulp is located on the side, lacking the long edge, of the side edge portion and seals the bag face portion in the side edge portion, and the hardness of a material of the side edge portion is greater than the hardness of the material of the bag face portion.

Description

technical field [0001] The invention relates to the field of flexible fingers, in particular to a flexible finger and a preparation method thereof. Background technique [0002] At present, soft actuating units and actuators made of elastic materials such as silicone rubber are deformed and actuated by using internal and external pressure differences. Generally, fluid (such as gas) is used as the driving medium to change the interior of the soft actuating unit. pressure to achieve differential pressure drive. [0003] As an example of a soft actuating unit or actuator, flexible fingers have many application scenarios in industry and commerce. Flexible fingers usually include an interface for air intake, multiple knuckles connected to the interface, and a one-to-one correspondence with the knuckles. The airbag, the double air channel connecting the multiple airbags and the interface, and the joint connecting two adjacent knuckles. [0004] However, the existing soft actuato...
