3D printing device and preparation method for gel-kind bionic artificial muscle

Abstract

The invention discloses a 3D printing device and preparation method for gel-kind bionic artificial muscle. The 3D printing device comprises a rack, a printing mechanism, a printing platform, a phase separating module, a laser cutting module, an electrode spraying module and a temperature control module, wherein the rack is of a gantry type structure, the printing mechanism is arranged at the bottom end of a stand column of the rack, the laser cutting module is arranged on a cross beam of the rack, the electrode spraying module is arranged on the side wall of the rack, symmetric guide rails arearranged on the two sides of rack, meanwhile, a driving device used for driving the printing platform to ascend and descend is arranged on the side wall, and the phase separating module is placed under the printing platform. The 3D printing device is suitable for continuously preparing the artificial muscle, printing artificial muscle strips with different specifications, and has the advantages that the preparation speed is high, the cost is low, batch and standardized production can be achieved; and an artificial muscle electrolyte layer is in close contact with an electrode layer, so that the contact resistance between the electrode layer and a driving layer is reduced, and then 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
