When the production conditions are met, the steps S2-S6 or the steps S1-S6 can be continuously produced in a roll-to-roll processing mode, so that the method is suitable for large-scale batch production, and when the roll-to-roll processing is adopted, a transition buffer and tension adjusting mechanism can be arranged on a production line for adjustment, so that the phenomenon that coiled materials are too tight or too loose is avoided, and the production feeding speed is controlled to meet the requirements. Cutting the coated coiled material into a proper size according to the requirement.
The foregoing description is only specific embodiments of the present invention and is not intended to limit the scope of the invention, and all equivalent structural changes made by the present invention and the accompanying drawings, or direct or indirect application in other related technical fields, are included in the scope of the present invention.
