The Influence Mechanism And Cooperative Regulation Of Injection Forming Elements Of Non-expanded Curved Surface On Conductive Patterns

The non-expanded curved surface conducting graph is a specific graph formed on the surface with conductive properties,and its preparation is one of the key steps in the production of conformal antenna,frequency selection surface and wearable electronic products.Traditional method is to splice on the surface using conductive plane graph,which has shortcomings with complicated technological process,poor accuracy of the conductive graphics forming,preparation on the surface of developable surface only.This paper is aimed at the problem that it is difficult to fabricate the conductive graph on the surface of non-expanded curved surface and to predict the shape of the three-dimensional conductive pattern forming.To solve the problem,firstly,the influence of the key injection forming factors on the forming quality of the conductive graph was studied,and the prediction model of the jet forming quality of the non-expanded curved surface was established.Secondly,the paper revealed how the factors of non-expanded curved surface conductive graphics injection forming influences the quality of the conductive pattern forming,and having realized the collaborative control between the injection forming elements based on BP neural network to achieve the optimum of the print quality.Finally,a non-expanded curved surface conductive graphics making method based on inkjet printing technology was put forward,which solved the shortcomings before,and the author developed a printing devices with the function of printing on a curved surface,to lay the foundation for the study of electronic equipments,such as high-performance conformal antennas,SMT electronics,frequency selective surface,etc.
