Embodiment Construction

[0047] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0048] Such as figure 1 and figure 2 As shown, the SMP composite grippers 5, 13, 16, and 33 are structures surrounded by the SMP composite material itself with a snake scale imitation structure. The SMP composite material is mainly composed of 4 periodic arrays of SMP composite material units to form a square planar structure. Each SMP composite material unit 4 includes a rubber sheet 3 and a plurality of strip-shaped SMP connecting sections 1 and 2 connected around the rubber sheet 3. Two adjacent SMP composite material units 4 are connected by respective SMP connecting sections 1 and 2, so that the SMP connecting sections 1 and 2 between adjacent two SMP composite material units 4 are connected to form a V shape.

[0049] The rubber sheet 3 is a regular hexagon, and each side of each rubber sheet 3 is connected to one side of the...

Abstract

The invention discloses a special-shaped grabbable storage and release device based on advanced composite material performance. A SMP composite material gripper is mounted at the bottom of a SMP composite material gripper installation frame, a stretching sliding rail groove supporting piece is fixedly mounted at the top of the SMP composite material gripper installation frame, and the stretching sliding rail groove supporting piece is fixedly connected with an upper rotating unit supporting sectional material through a connecting piece; the SMP composite material gripper is of a structure defined by an SMP composite material; and the stretching sliding rail groove supporting piece and the SMP composite material gripper installation frame are connected with the tail end of the SMP composite material gripper through a plurality of connecting rods. The used composite material refers to a snake scale structure, and through combination of the shape memory polymer SMP and rubber, the device not only has the characteristic of SMP memory deformation, but also has good stretching and bearing capacities and very large variable stiffness capacity, so that the device can adapt to objects in various shapes, and grabbed objects can be safely and effectively stored.

Description

technical field [0001] The invention relates to a grasping device, in particular to a special-shaped graspable storage release device based on the performance of advanced composite materials. Background technique [0002] Due to the deformability and flexibility of the materials used, the soft manipulator has the characteristics of high flexibility, complex environment adaptability and safe human-computer interaction. It has received extensive research by domestic and foreign scholars. Space, deep-sea exploration and other fields have good application prospects. Although the soft manipulator has various excellent performances, there are still problems such as small driving force, weak carrying capacity, single material deformation, lack of accurate dynamic model, and inability to control accurately. These problems largely affect the application of soft manipulators in various aspects. Contents of the invention [0003] In order to solve the problems existing in the backg...
