Problems solved by technology

Pneumatic soft grippers are more suitable for grasping fragile and fragile objects than rigid grippers, and have a wide range of application prospects. However, due to the limitations of their materials, the stiffness of flexible grippers is often low, and it is impossible to achieve large-mass objects. Grabbing, and the pneumatic fingers need to maintain a bent state during the grasping process to make the gripper envelope the object to achieve gripping, which has caused great restrictions on the application of pneumatic flexible grippers

Embodiment Construction

[0017] Such as figure 1 with figure 2 As shown, this embodiment includes: a pair of pneumatic fingers 6 relatively slidably arranged on the gripper fixing frame 1, wherein: the opposite sides of the pneumatic fingers 6 are provided with a detachment air chamber 7 and a dry adhesive layer 8 in sequence.

[0018] The sliding setting is realized by connecting the handle fixing frame with the adjustment groove 103 on the handle fixing frame 1 and the pneumatic fingers respectively.

[0019] Such as figure 1 As shown, the position of the handle fixing frame 2 can be adjusted on the handle fixing frame 1 and fixed on the handle fixing frame 1 through the adjustment groove 103 using bolts 101 and nuts 102 .

[0020] The gripper fixing frame 2 is used to install and fix the top of the pneumatic finger 6, use the compression plate 3 to compress the pneumatic finger 6 to fix it in the gripper fixing frame 2, use the bolt 4 and the nut 5 to connect the gripper and fix it The frame 2 ...

Abstract

The invention relates to a self-adaptive dry adsorption-desorption functional pneumatic flexible gripper. The self-adaptive dry adsorption-desorption functional pneumatic flexible gripper comprises apair of pneumatic fingers arranged on a gripper fixing frame in an opposite sliding mode, separation air chambers and dry adhesion layers are sequentially arranged on the opposite side faces of the pneumatic fingers, each dry adhesion layer comprises a left adhesion layer body, a right adhesion layer body and micron-sized wedge-shaped protrusions located on the adhesion layer bodies, directional deformation is generated through the wedge-shaped protrusions, the contact areas between the dry adhesion layers and a contacted object are increased, and the Van der Waals' force and the adsorption force between the dry adhesion layers and the object are improved. According to the self-adaptive dry adsorption-desorption functional pneumatic flexible gripper, by improving the adsorption force, theobject grabbing quality of the pneumatic gripper is improved, meanwhile, the grabbing action of the gripper is simplified, and grabbing of the object can be achieved without wrapping the object.

Description

technical field [0001] The invention relates to a technology in the field of robots, in particular to an adaptive dry adsorption-desorption functionalized pneumatic flexible gripper. Background technique [0002] The fingers of the pneumatic flexible gripper used for soft robots generally expand and bend after being fed with compressed gas, and the pneumatic gripper composed of this can produce a palm-like grasping action after being fed with compressed gas. Pneumatic soft grippers are more suitable for grasping fragile and fragile objects than rigid grippers, and have a wide range of application prospects. However, due to the limitations of their materials, the stiffness of flexible grippers is often low, and it is impossible to achieve large-mass objects. Grabbing, and the pneumatic fingers need to maintain a bent state during the grasping process to make the gripper envelope the object to achieve gripping, which has caused great restrictions on the application of pneumati...
