A gel bionic artificial muscle 3D printing device and preparation method

Abstract

The invention discloses a 3D printing device and a preparation method of a gel bionic artificial muscle. The 3D printing device includes a frame, a printing mechanism, a printing platform, a phase separation module, a laser cutting module, an electrode spraying module, and a temperature control module. The frame is a gantry structure, the printing mechanism is installed at the bottom of the frame column, the laser cutting module is installed on the frame beam, the electrode spraying module is installed on the side wall of the frame, and symmetrical guide rails are installed on both sides of the frame. At the same time, the side wall There is a driving device for driving the printing platform up and down, and the phase separation module is placed under the printing platform. This device is suitable for continuous preparation of artificial muscles and printing of artificial muscle strips of different specifications. It has the advantages of fast preparation speed, low cost, batch production and standardized production; the artificial muscle electrolyte layer is in close contact with the electrode layer, reducing the contact resistance between the electrode layer and the driving layer. Thus, the deflection displacement and driving force of the artificial muscle are enhanced.

Description

technical field [0001] The invention relates to the technical field of artificial muscles, in particular to a 3D printing method for preparing artificial muscles. Background technique [0002] The development of drive technology has gone through steam engines, internal combustion engines, and electric motors, and the flexibility, ease of use, and energy utilization of mechanical systems have also been greatly improved. However, high-performance robots (miniature, bionic robots) require high flexibility, high redundancy, high efficiency, and high load / mass ratio, and motors are still difficult to meet. Most of the various movement modes of organisms are realized through muscle stretching and stretching, so artificial muscles have become one of the hot issues in scientific research. The artificial muscle is mainly composed of an ionic polymer film in the middle and metal electrodes on both sides, commonly known as a "sandwich" structure. The preparation process is mainly to a...

AI Technical Summary

Problems solved by technology

In the preparation method, the precipitation method precipitates a colloidal metal on both sides of the film, but the metal electrodes on both sides of the artificial muscle prepared by this method cannot be well attached to both sides of the film, and the metal electrodes are easy to fall off

In the traditional process method, the actuating film and the electrode film of the driver are formed independently, and then assembled together by thermocompression bonding. This method cannot guarantee that all parts of the surface of the electrode film and the driving film can Good fit together, from the microscopic scale, there will still be many surfaces in the state of separation or poor contact, which makes the contact resistance value too large, the performance of the driver is limited by the proficiency of the operator, and the performance is relatively poor. Stablize

The direct casting method is different from the hot-press lamination process. It casts the driving layer film and the electrode film together during the film-forming stage. This method has obvious advantages over the previous three methods. The contact between the driving layer and the electrode layer is not easy to crack, but The process of casting method is complicated, the efficiency is low, the cost is high, and it cannot be mass-produced
