Electric fluid dynamic spray printing equipment for flexible dielectric substrate and control method

Abstract

In order to solve the problem that existing electric fluid dynamic spray printing equipment cannot meet electric fluid dynamic spray printing of a flexible dielectric substrate, the invention provideselectric fluid dynamic spray printing equipment for the flexible dielectric substrate and a control method. The electric fluid dynamic spray printing equipment comprises a support, a spray printing module and a spray printing platform. The spray printing module is arranged on the support through an X-axis slipping mechanism and a Z-axis slipping mechanism, and a spray head is arranged on the spray printing module, and a working platform is arranged on the spray printing platform. The working platform comprises a bottom plate and a plurality of supporting assemblies, and each supporting assembly comprises a first position in mounting and a second position for supporting the flexible dielectric substrate to be subjected to spray printing to form a hook face in working. According to the method, the equipment is adopted to conduct spray printing. According to the electric fluid dynamic spray printing equipment and the control method, the flexible dielectric substrate to be subjected to spray printing can be arranged into the hook face of a preconceived object subjected to spray printing, the spray printing effect of the flexible dielectric substrate is good, and accurate forming of apattern on the complex hook face is achieved.

Problems solved by technology

Although this method has a relatively simple structure and convenient printing, since flexible electronics will be bent or stretched during use, this deformation will affect the tiled printing pattern, thereby affecting the characterization and performance of flexible electronics. In severe cases, it may even cause open circuit of flexible electronics, thus affecting the service life and reliability of flexible electronics
