Embodiment 1

[0029] Such as figure 1 , 2 .

[0030] A manipulator device based on unidirectional thermotropic shape memory polymer, including a clamping part 1 , a deformation part 3 and a base 5 . Clamping part 1 is made of carbon fiber / epoxy shape memory composite material, deformation part 3 is made of styrene shape memory polymer foam material, base 5 is made of carbon powder / epoxy shape memory composite material, fasteners 2, 4 Made of epoxy polymer. Among them, the clamping part 1 is fixed on the base 5 by fasteners (bolts), and the deformation part 3 is connected between the base 5 and the clamping part 1 by fasteners (bolts). In order to facilitate deformation, the connecting part should can maintain relative rotation. The deformation part 3 and the base 5 are embedded with resistance wires, the carbon fiber in the clamping part 1 is a conductor, and all three are connected to the power supply.

[0031] When implementing it:

[0032] At least one of the clamping part 1 and th...

Embodiment 2

[0036] Such as image 3 , 4 .

[0037] A manipulator device based on two-way shape memory polymer, including a clamping part 1 , a fastener 4 and a base 5 . The clamping part 1 is made of carbon fiber / heterophase copolyester-urethane copolymer composite material with two-way shape memory, and its glass transition temperature is 35 ° C and 65 ° C respectively; the fastener 4 and the base 5 Made of epoxy polymer. The clamping part 1 is fixed on the base 5 by the fastener 4 .

[0038] When implementing it:

[0039] At least one of the clamping components 1 has been pre-deformed. The pre-deformation can be one or more combinations of stretching, bending, twisting, curling or compression, and the base 5 can be a shape-memory polymer body or a conventional polymer body. The two-way shape memory polymer is one or more combination of pure polymer, polymer foam or polymer composite material. The polymer composite material is a composite material formed by blending and compounding ...

Abstract

A corrosion-resistant lightweight manipulator based on shape-memory polymers, which is characterized in that it is mainly composed of clamping parts, fasteners, bases, etc., and all components are made of polymer materials. It has the advantages of simple structure, light weight, no oil supply and foldable. The invention further expands the scope of use of the manipulator, which can greatly reduce the labor intensity of the operator, ensure the personal health of the operator, and realize safety. Efficient production.

Description

technical field [0001] The invention relates to a gripping mechanical device, in particular to a manipulator used in special industries, in particular to a corrosion-resistant lightweight manipulator based on a shape memory polymer that can withstand strong acid and strong alkali corrosion. Background technique [0002] In the harsh environment of high temperature, high pressure, radioactivity and toxic pollution, the application of manipulators can partially or completely replace the operator for production, thereby reducing the labor intensity of the operator, ensuring the personal health of the operator, and achieving safe and efficient production. However, most of the manipulators currently on the market are made of metal. Although they have high strength, accurate and fast movements, they have limited corrosion resistance and are not suitable for use in certain special environments (such as strong acid and strong alkali environments). For example, in industrial producti...
