Manipulator device driven on basis of photo-induced shape memory polymers and method thereof

Abstract

The invention relates to a manipulator device driven on the basis of photo-induced shape memory polymers and a method thereof. One end of a photo-induced shape memory polymer laminated beam is fixedly arranged in a clamping groove between a base and a fixture block; a metal protection sheet is adhered to the other end of the photo-induced shape memory polymer laminated beam in order to protect the photo-induced shape memory polymers; a claw arm is the photo-induced shape memory polymer laminated beam and comprises three layers; the top layer and the bottom layer are made of the photo-induced shape memory polymers; the middle layer is an elastic beam; the layers are mutually adhered by high-intensity viscous materials; the fixture block and a fastening bolt are arranged on the base; the end part where the fastening bolt is arranged is matched with a screw thread hole of the base after passing through a through hole of the base; the clamping groove formed between the fixture block and the base is used for fixing the end part of the photo-induced shape memory polymer laminated beam; a gap of the clamping groove can be regulated according to the thickness of the photo-induced shape memory polymer laminated beam. The manipulator has the characteristics of simple and intelligent structure, non-contact control, light weight and the like and is suitable for a common micro electro mechanical system.

Description

technical field [0001] The invention relates to a mechanical claw device, in particular to a mechanical claw device driven by a photoinduced shape memory polymer and a method thereof. Background technique [0002] As a traditional and practical grabbing tool, mechanical claws are widely used in automated production and manufacturing. However, the power sources of traditional mechanical claws are mostly servo motors, air pressure and hydraulic pressure, and their structures are relatively complex. The ratio is small. Therefore, mechanical claws driven by smart materials have become a new research and development direction. [0003] In recent years, relevant researchers have vigorously developed mechanical claws driven by smart materials, and have achieved a series of research results. At present, more mature smart materials include shape memory alloys and piezoelectric materials. The mechanical claws based on shape memory alloy materials use temperature changes to real...

AI Technical Summary

Problems solved by technology

At present, more mature smart materials include shape memory alloys and piezoelectric materials. The mechanical claws based on shape memory alloy materials use temperature changes to realize the phase transition between martensite and austenite in shape memory alloy materials. The stress is used as the power source, but the temperature drop process is relatively slow, and if the corresponding heat dissipation device is used, the complexity of the entire system will be increased

The mechanical claw based on piezoelectric material uses the inverse piezoelectric effect to convert electrical energy into mechanical energy output. Its actuation frequency is high, but the stroke at the end of the mechanical claw is small.

In addition, limited by the use of power supply lines, the above two mechanical grippers cannot achieve non-contact control
