Problems solved by technology

However, the shielding devices in the existing technology are mostly fixed. In addition, the structure and shape of the through groove on the shielding device cannot be changed, so that one device can only process one type of film. If the shielding device can be automatically changed, The opening area of ​​the evaporation boat and the distance between it and the evaporation drum are adjustable, which can meet the production of various types of films
[0005] (3) During the transportation of the insulating film, if the tension is not uniform, the phenomenon of floating will be found, which will affect the normal transmission of the film

Embodiment Construction

[0042] In order to further describe the present invention, it is further described below in conjunction with embodiment.

[0043] Such as figure 1As shown, the present invention discloses a secondary vacuum coating machine for metallized film thickening, including a vacuum chamber 401 and a feeding mechanism, a coating mechanism, and a winding mechanism arranged in the vacuum chamber 401 . The feeding mechanism, the coating mechanism, and the winding mechanism are arranged in sequence from front to back according to the process flow.

[0044] Such as figure 1 As shown, the feeding mechanism includes a first lifting mechanism 101 and a feeding device. The telescopic end of the first lifting mechanism 101 cooperates with the feeding device to drive the feeding device to move up and down.

[0045] Such as figure 1 As shown, the vacuum chamber 401 includes a chamber entrance door 4011 at the entrance end and a chamber exit door 4012 at the exit end.

[0046] Such as figure 1...

Abstract

The invention discloses secondary vacuum coating equipment for a thickening metalized thin film. The equipment comprises a vacuum chamber, and a feeding mechanism, a coating mechanism and a winding mechanism which are arranged in the vacuum chamber. A first movable plate assembly which adjusts the size of an opening of a first evaporation boat is arranged in a top opening region of the first evaporation boat; a second movable plate assembly which adjusts the size of an opening of a second evaporation boat is arranged in a top opening region of the second evaporation boat; and thin film limiting devices are arranged between the feeding mechanism and the coating mechanism and between the coating mechanism and the winding mechanism. The secondary vacuum coating equipment disclosed by the invention has the advantages of being high in degree of automation, capable of supplementing and receiving materials conveniently, immediate, capable of uniformly preheating, adjustable in preheating quantity, suitable for machining films of various multiple models and capable of adjusting coating thickness.

Description

technical field [0001] The invention relates to the technical field of coating machines, in particular to a secondary vacuum coating machine for thickening metallized films. Background technique [0002] The metallized film is the main part of the capacitor, and its quality directly affects the service life of the capacitor. At present, the metallized film is mainly processed and prepared by a vacuum coating machine, including an insulating film feeding mechanism, a coating mechanism, and a film winding mechanism after the metal layer is plated. Yet the vacuum coater of prior art has the following weak points: [0003] (1) The coating mechanism melts the metal through the evaporation boat, so that the metal evaporates to the insulating film on the surface of the evaporation drum to form a metal layer and realize the coating process. However, the distance between the evaporation drum and the evaporation boat in the traditional coating mechanism is mostly a fixed value; more...
