Embodiment Construction

[0021] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, so that those skilled in the art can better understand the present invention and implement it, but the examples given are not intended to limit the present invention.

[0022] refer to Figure 1-5 As shown, a robot flexible finger structure includes a finger body, and the finger body includes a finger bottom plate 1 and a finger finger surface 2, and the finger finger surface 2 is connected to one side of the finger bottom plate 1, and the finger finger surface Surface 2 includes fingertip 21, knuckle and root of finger. Air inlet 3 is arranged on the base of finger. The knuckle part includes finger peak 23 and finger valley 24. A plurality of flat semicircular shapes are arranged inside the knuckle part. The air cavity 22, a plurality of the air cavities 22 are communicated through an air passage 25, and the deformation of the finger base 1 is s...

Abstract

The invention relates to the technical field of industrial robots, in particular to a flexible finger structure of a robot. The flexible finger structure has the advantages of being high in response speed, high in bearing capacity, stable and reliable and the like. By adopting a structure that deformation of a finger bottom plate is smaller than that of knuckles and a gas cavity distribution modeof arranging multiple gas cavities in series, when air of certain pressure is introduced to a gas circuit, a flat semicircular gas cavity expands, and adjacent gas cavities extrude each other, so thata finger body bends toward the finger bottom plate and a material grabbing space is formed among the flexible fingers, and therefore, the grabbing using range is wider. Meanwhile, the flexible fingerstructure is simple in adopted driving mode, easy to control and low in cost. The knuckle parts comprise finger peaks and finger valleys, so that tension generated by the knuckle parts when the flexible fingers bend is reduced, and therefore, the flexible fingers have a better bending effect.

Description

technical field [0001] The invention relates to the technical field of industrial robots, and relates to a robot flexible finger structure. Background technique [0002] In the field of industrial automation, the grasping action at the end of the robotic arm is mainly completed by rigid mechanical grippers or vacuum suction cups. However, due to the difficulty in controlling the strength of rigid mechanical grippers, it is difficult to achieve non-destructive grasping of soft and fragile objects. It is difficult for vacuum suction cups to adapt to irregular objects with rough surfaces and holes during handling, which leads to limitations in the application scenarios of both. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a robot flexible finger structure with simple driving mode, easy control and low cost. [0004] In order to solve the above technical problems, the technical solution adopted by the present in...
