A production process of origami teaching aids based on conductive ink

Abstract

The invention provides a paper folding teaching tool manufacturing process based on conductive ink. The process comprises the steps of firstly designing the pattern of the paper folding teaching tool,determining each crease position and a conductive ink path of the paper folding teaching tool, then printing the conductive ink on the surface of paper according to the relation between each crease position and the conductive ink path, and then adhering electronic elements on the surface of the paper. According to the paper folding teaching tool manufacturing process, printing layers of the conductive ink are designed for aiming at paper folding characteristics; one layer of conductive ink is printed on the non-crease position, thereby reducing the number of printing; two layers of conductiveink are printed on the crease, thereby reinforcing the conductive ink at the crease, realizing no easy ink falling, ensuring moderate thickness of the conductive ink, and realizing stable resistanceafter folding. At a folded position without conductivity caused by folding, insulating ink is printed, thereby ensuring no conductivity at the insulator at the folding part. The whole folding paper surface is provided with at most two layers of conductive ink and one layer of insulating ink, namely the front surface and the back surface can be wholly manufactured through printing by three times. The paper folding teaching tool manufacturing process has advantages of simple process step, easy application and easy batch production.

AI Technical Summary

Problems solved by technology

However, although conductive ink has certain ductility and seems to be easy to combine with paper, it is only used on flat surfaces such as posters and book pages at this stage, and has a certain degree of curl resistance.

To apply conductive ink to origami, there are still technical difficulties in the process, such as how to conduct or insulate the conductive ink on the upper and lower contact surfaces after folding, how to ensure the adhesion effect of the conductive ink at the crease, and the crease during the folding process. There is a change in the resistance of the conductive ink at the place, how to avoid this change from causing a major impact on the effect of the entire circuit, etc.
