Embodiment 1

[0054] Please also refer to Figure 1-4 , figure 1 It is the processing flow chart of the shielding film in the prior art. In the prior art, the coating production of the shielding film is mainly to coat the insulating layer on the carrier film to obtain a semi-finished product, and coat the conductive layer glue on the outside of the semi-finished product, and finally in the The outer side of the conductive layer is pasted with a protective film to form a shielding film. In actual production, a metal layer can be selected to be processed on one side of the insulating layer according to needs.

[0055] Such as figure 2 As shown, this embodiment provides a shielding film processing system, including a semi-finished product processing system 100 and a finished product processing system 200, specifically:

[0056] The semi-finished product processing system 100 is used for coating an insulating layer on the carrier film to make a semi-finished product of the shielding film;

...

Embodiment 2

[0068] This embodiment provides a method for processing a shielding film using the shielding film processing system in Embodiment 1, including:

[0069] Coating an insulating layer on the carrier film to produce a semi-finished product, which can be completed by the semi-finished product processing system 100;

[0070] A conductive layer is coated on the protective film, and the side of the conductive layer facing away from the protective film is combined with the side of the insulating layer facing away from the carrier film to make a finished product. The finished product can be finished by the finished product processing system 200 .

[0071] Coating an insulating layer on a carrier film to make a semi-finished product is:

[0072] Coating an insulating layer on one side of the carrier film, the carrier film can be sent to the first coating device 120 through the first sending device 110, and then utilize the coating head of the first coating device 120 to coat the insulati...

Abstract

The invention provides a processing system and method for a shielding film and relates to the technical field of electromagnetic shielding. The processing system for the shielding film comprises a semi-finished product processing system and a finished product processing system. The semi-finished product processing system is used for coating a carrier film with an insulation layer so as to obtain a semi-finished shielding film. The finished product processing system is used for coating a protective film with a conducting layer and compositing the conducting layer with the insulation layer so as to obtain the finished shielding film. The technical problems of nonuniform coating, reduced coating continuity, appearance defects, and affecting of product performance caused by the fact that in the prior art, a semi-finished shielding film is directly coated with conducting layer glue are solved. The finished product processing system coats the protective film with the conducting layer firstly and then composites the conducting layer with the insulation layer of the semi-finished product, and accordingly the shielding film is obtained, so that the appearance and performance of the shielding film are better.

Description

technical field [0001] The invention relates to the technical field of electromagnetic shielding, in particular to a processing system and method for a shielding film. Background technique [0002] Electromagnetic shielding is widely used in communication, electronic products, network hardware, medical equipment, aerospace and national defense and other fields. In terms of communication, electromagnetic shielding is to isolate metal between two space regions to control electric fields, magnetic fields and electromagnetic waves. Induction and radiation of an area to another area. Specifically, it is to use a shield to surround the interference source of components, circuits, assemblies, cables or the entire system to prevent the interference electromagnetic field from spreading outward, and to surround the receiving circuit, equipment or system with a shield to prevent them from being affected by the outside world. Electromagnetic shielding film is a commonly used shielding ...
