Embodiment Construction

[0020] The specific implementation manner of the present invention will be described below in conjunction with the accompanying drawings.

[0021] Such as figure 1 with figure 2 As shown, the flexible gripper with surface microstructure of this embodiment includes a motor 8, and the end of its output shaft is connected with a bending grabbing mechanism through a connecting body 7; One end of 5 communicates with the inflation nozzle 6 arranged on the surface of one side of the connecting body 7, and the other end communicates with the bending grabbing mechanism; The bottom surface is connected, and the bottom end is a free end. An elastic body 10 is connected to one side of the flexible finger fingerboard 4. The elastic body 10 is sequentially connected into a whole by a plurality of interconnected airbags 3 along the length direction. The inside of each airbag 3 It has an inflatable cavity 9, and the inflatable cavities 9 of two adjacent airbags 3 are connected through the ...

Abstract

The invention relates to a flexible gripper with a surface micro structure. The flexible gripper includes a motor, a bending grabbing mechanism is connected to the end part of an output shaft of the motor through a connecting body; an air guiding channel is formed in the connecting body, one end of the air guiding channel communicates with an inflating connector on the surface of one side of the connecting body, and the other end of the air guiding channel communicates with the bending grabbing mechanism; the structure of the bending grabbing mechanism includes a flexible finger plate, the topend of the flexible finger is connected with the bottom surface of the connecting body, the bottom end of the flexible finger plate is the free end, an elastomer is connected to one side of the flexible finger plate and is formed to a whole by connecting a plurality of mutual communicating air bags in the length direction sequentially, an inflating cavity is formed in each air bag, the inflatingcavities of the every two adjacent air bags are in communication through an air channel, and the inflating cavity of the air bag located at the top most communicates with the air guiding channel; andunder the uninflated state, the sizes of the inflatable cavities of the air bags decrease in sequence in the direction away from the connecting body. According to the flexible gripper with the surfacemicro structure, effective grasping of objects with the complex shapes and regular structures can be met.

Description

technical field [0001] The invention relates to the technical field of robotic hands, in particular to a flexible gripper with a surface microstructure. Background technique [0002] At present, the most widely used robotic grippers in industrial applications are rigid grippers. However, rigid grippers have limitations in principle and can only grasp a few regular-shaped objects. Moreover, they are costly, difficult to control, and have strict environmental requirements, which are far from meeting the needs of logistics. , housekeeping services, rescue and other emerging industries. Most of the traditional flexible grippers use the connection of multiple tiny rigid components to achieve the purpose of "flexibility", but their essence is still rigid grippers. In today's flexible manufacturing, these are difficult to meet the effective grasping of products with complex shapes and various types. Contents of the invention [0003] The applicant aims at the shortcomings in th...
