Manufacturing device, manufacturing method and application of conductive grid type touch sensing layer

Abstract

The invention relates to a manufacturing device, a manufacturing method and application of a conductive grid type touch sensing layer. When the manufacturing device is used, insulating glue liquid iscontained in a glue wrapping cavity of a printing and laying head, and when a wire to be printed and laid passes through the glue wrapping cavity, the insulating glue liquid wraps the wire. When the wire is led out of a wire outlet hole to a substrate, the insulating glue solution wraps the wire and is extruded together with the wire. And the wire wrapped by the insulating glue solution is adheredto the surface of the substrate after being contacted with the substrate. Because the insulating layer can be formed after the insulating glue solution is cured, the conductive grid formed on the substrate has an insulating characteristic, and the insulating property is very good when the conductive grid is overlapped with metal grids of other layers. According to the manufacturing device and method of the conductive grid type touch sensing layer, a special adhesive layer does not need to be preset on the substrate to fix the wire, and the conductive grid type touch sensing layer can be laidon substrates of different materials, structures and shapes, and the manufacturing device and method have the advantages of being wide in application range, easy to operate and the like.

Description

technical field [0001] The invention relates to the technical field of touch screens, in particular to a manufacturing device, a manufacturing method and an application of a conductive mesh touch sensing layer. Background technique [0002] Metal mesh is a conductive mesh formed on the substrate by micromachining technology. It has the advantages of good conductivity, high light transmittance and strong anti-interference ability. At present, metal mesh technology has been applied to touch screens. manufacturing. Traditional micromachining techniques for metal mesh production include photolithography, embossing, silk screen printing, and printing. Among them, the yellow light process is mainly used for copper, nickel, silver and other pure metal conductors; embossing and screen printing processes are mainly used for mixed conductors such as silver paste; the printing method is mainly used for mixed conductors, enameled wires, etc. Among the above-mentioned methods, printing...

Problems solved by technology

However, at present, the printed metal grid is mainly laid on the substrate with glue by using enameled wire, and the conductive material is pasted on the substrate by using the viscosity of the glue, and this technology is generally only suitable for making on the film substrate, which has certain limitations and structural restrictions. sex

In addition, in terms of reliability, because the two layers of wires need to be pasted, the current technology has some short circuit risks and insufficient insulation
