Abstract

The invention relates to a vacuum evaporating coating machine of films for aluminum thickened metalized capacitors. An evaporation source comprises a first aluminum crucible and a second aluminum crucible, wherein the first aluminum crucible is installed on one side wall of a vacuum evaporation coating chamber for synchronously performing an aluminum film evaporation coating step, and the second aluminum crucible is used for an aluminum reinforced layer evaporation coating step. After aluminum film evaporation coating, an aluminum reinforced layer can be quickly coated by vaporization on the surface coated with an aluminum film by vaporization; the two evaporation steps are synchronously performed; and the thickening of the reserved side of the aluminum metalized capacitor is realized. The machine has the greatest advantages that a natural oxide layer is formed, the capability of moisture resistance is high, the storage cycle is long, the natural repair performance is good, metalized films can produce Al2O3 after natural repair, and the parameters of the capacitor arrre not affected. Simultaneously, the machine improves the quality of the whole coating film, and simultaneously improves the evaporation efficiency, and solves the problem that the traditional vacuum evaporating coating machine at home and abroad can not prepare films of aluminum thickened metalized capacitors. Simultaneously, the vacuum evaporating coating machine of films for aluminum thickened metalized capacitors can also be used for producing films for pure aluminum metalized capacitors.

Description

technical field [0001] The invention relates to a vacuum evaporation coating machine for thin films for metallized capacitors, in particular to a vacuum evaporation coating machine for aluminum thickened thin films for metallized capacitors. Background technique [0002] Existing films for metallized capacitors are based on base films (such as insulating materials such as polyester films and polypropylene films) as dielectric materials, using a vacuum coating machine to coat metal plates with metal heating and evaporation technology under high vacuum conditions. , The metal level board can be divided into two layers of single aluminum coating and aluminum thickening. Because of its unique self-healing characteristics, it is widely used in the manufacture of various types of AC capacitors and DC filter capacitors for power compensation or motor starting. The unique self-healing properties of the metallized film can significantly improve and increase the voltage resistance and...
