Background

Calcium Alginate Hydrogel (CAH) is an intelligent material of ionic electrically-actuated polymer, the actuating performance of the calcium alginate hydrogel is very similar to that of biological muscle, generally called as 'artificial muscle', and the calcium alginate hydrogel has wide application value in the fields of bionic manufacturing and the like. The CAH artificial muscle consists of an electric actuating membrane and two electrode membranes, wherein the two electrode membranes cover two sides of the electric actuating membrane respectively and are jointed to form an electric actuator similar to a sandwich structure. The response performance is an important index for measuring the CAH artificial muscle, and the process of assembling and drying the CAH artificial muscle directly influences the quality of the response performance of the CAH artificial muscle. At present, researchers at home and abroad are actively exploring the technological process for assembling CAH artificial muscles, but lack developed and mature and suitable assembling and drying appliances. Therefore, a set of experimental assembly drying die with simple structure and reliable precision is researched and developed, the assembly efficiency of the CAH artificial muscle and the success rate of drying and film forming can be greatly improved, and the method has important significance for further wide application.

The "Polymer compositions" journal of the "contamination and application of a muscle like linear actuator using polymeric compositions" published in 2015 uses a small biological petri dish and a chemical beaker as the assembly and drying mold for the linear actuator. However, in the assembly process, only a single film formation can be performed for each electric actuator, and rapid mass production cannot be achieved, resulting in low working efficiency. In addition, the thickness of the dried film cannot be accurately controlled, so that the performance quality of each piece of the linear actuator after cutting and forming is inconsistent.

The invention aims to provide a drying die for batch assembly of CAH artificial muscles, which is simple in structure, reliable in precision, easy to operate and high in assembly efficiency and is used in scientific research experiments. Meanwhile, the CAH artificial muscle formed by assembling the drying die can improve the integral response performance of the CAH artificial muscle and achieve the consistency of each piece.

The purpose of the invention is realized as follows:

a drying die for an experiment for assembling CAH artificial muscle mainly comprises a communicated grid type support and a die box body. The grid-type bracket is correctly arranged in the mould box body along the guide line groove on the inner wall of the mould box body. The interior space of the mold box is divided evenly into equal volume portions, similar to the common "grid" structure space. So that a number of individual electro-actuators can be assembled and formed by drying the membrane solution of a CAH artificial muscle once. Meanwhile, the connecting parts of the corners of the communicated grid type bracket are provided with mutually communicated pore channels, so that when each layer of membrane solution of each artificial muscle is dried, the volume of each small grid space is equal. The film thickness of the assembled and molded film is consistent in the same layer, each layer is controllable, and the performance quality is the same. In addition, the inner wall sides of the mold box body and the communicated grid type support are all provided with scale scales for indicating the drying capacity, so that the thickness of each layer of artificial muscle membrane after assembly and forming can be accurately controlled.
