Front and back automatic laminating machine and laminating method of multi-hollow metal sheet

Abstract

The present invention relates to an automatic film laminating machine and a film laminating method for the front and back of multi-hollow metal sheets. Both the lamination system and the second lamination system can move and tear off the release film along the combined force direction of the X-axis and the Z-axis, and both the first lamination system and the second lamination system can move between the first vacuum chamber and the second lamination chamber. 2. Complete the back and front film of the metal sheet in the vacuum chamber. On the one hand, the present invention gradually separates the release film and the film to be attached along the direction of force synthesis when tearing the film, which greatly reduces the probability of film damage caused by tearing the film; on the other hand, it does not need to flip the metal sheet. The alignment film on the front or back of the metal sheet is carried out under the vacuum chamber, which not only has a low probability of bubbles, but also ensures the accuracy and quality of the multi-hollow metal sheet.

Description

technical field [0001] The invention belongs to the technical field of vacuum coating of metal sheets, and in particular relates to an automatic front and back film lamination machine for multi-hollow metal sheets, and also relates to an automatic front and back film lamination method for multi-hollow metal sheets. Background technique [0002] At present, the laminating machine used in the market is mainly to paste the PET film with the release film removed on the surface of the corresponding metal sheet, and the laminating machine includes a PET film supply unit, a film tearing unit, a film unit, and a metal sheet transmission unit. , where the length direction of the PET film is the X-axis, the width direction is the Y-axis, and the thickness direction is the Z-axis. The PET film supply unit mainly feeds each piece of PET film to the film unit, and the film tearing unit is mainly used to apply the film. The release film on the surface of the film is torn off, and the film...

AI Technical Summary

Problems solved by technology

[0004] 1. Before sticking the film, it is necessary to tear off the release film with hollow holes. However, due to the difficulty in controlling the angle and strength of the tear film, when the release film is torn off, there is a high probability that the film will be damaged ( Such as: tearing or tearing off), in this way, not only the scrapping rate of the lamination film is high, but also the film supply efficiency of the lamination film is greatly reduced;

[0005] 2. When sticking the film, the phenomenon that will appear the most under normal circumstances is: air bubbles, so for the laminating film with hollow holes, the probability of bubbles is greater, so the accuracy of the film is difficult to guarantee;

[0006] 3. After the front film of the metal sheet is completed, when the back film is required, at this time, the metal sheet needs to be turned 180°, and then the back film is applied. In this way, not only the transmission process of the metal sheet is very complicated, but also Due to the change of the positioning reference, it is difficult to grasp the accuracy of the back film, so it is difficult to meet the film precision requirements;

[0007] 4. The film tearing process and the film sticking process are two completely independent processes, and the film is generally peeled off after the film is pasted. Therefore, it takes a long time to wait for each film sticking, and the film sticking efficiency is low.
