Anti-oxidation metalized film, and preparation device and processing method thereof

Abstract

The invention discloses an anti-oxidation metalized film, and a preparation device and a processing method thereof. The anti-oxidation metalized film comprises a base film, and a first adhesion grooveis formed in the top surface of the base film; a second adhesion groove is formed in the bottom surface of the base film, and adhesive glue is injected into the first adhesion groove; an anti-oxidation metal layer is evaporated on the top surface of the base film, and a reserved edge is arranged on one side of the anti-oxidation metal layer; the preparation device comprises a machine body, and amotor and a feeding box are arranged on the outer side walls of the machine body; a rolling mechanism, a first roller and a second roller are perpendicularly connected between the inner side walls ofthe machine body, and a limiting wheel is connected with the side, close to a winding column, of the inner side wall of the machine body; and a delivery mechanism is arranged at the inner bottom of the machine body. The processing method comprises the steps of S1, preparation of the base film; and S2, evaporation of the anti-oxidation metal layer. According to the anti-oxidation metalized film, the first adhesion groove and the second adhesion groove are machined in the surface of the base film, so that the anti-oxidation metal layer can be attached to the base film more tightly; And the adhesive glue is injected into the first adhesion groove, so that the adhesion rate of the evaporated metal layer on the base film is effectively improved, and it is ensured that the structure of the capacitor is more stable.

Description

technical field [0001] The invention belongs to the technical field of metallized films, in particular to an anti-oxidation metallized film and a preparation device and method thereof. Background technique [0002] Two conductors that are close to each other, with a layer of non-conductive insulating medium in between, constitute a capacitor. A capacitor stores charge when a voltage is applied between its two plates. Capacitors play an important role in tuning, bypassing, coupling, filtering and other circuits. [0003] In the manufacturing process of capacitors, the winding process is usually adopted, and the circuits attached to various metallized films are wound together to reduce the volume. The existing capacitors use the base film attached with a metal layer as the basis , usually the metal layer is oxidized, and when the metal layer is attached to the base film, the adhesion rate is usually not high, which leads to the instability of the internal structure of the me...

[0003] In the manufacturing process of capacitors, the winding process is usually adopted, and the circuits attached to various metallized films are wound together to reduce the volume. The existing capacitors use the base film attached with a metal layer as the basis , usually the metal layer is oxidized, and when the metal layer is attached to the base film, the adhesion rate is usually not high, which leads to the instability of the internal structure of the metallized film, thus affecting the normal use of the capacitor
