Vehicle license plate laminate film attachment device

The present invention relates to the manufacture of license plates, and more particularly, a technology for stably attaching a film for protecting license plates while removing air bubbles. It relates to a laminate film attachment device.

In general, a license plate or panel may be in the form of a simple flat plate or in various forms, and is applied to various devices requiring display surfaces of various radii of curvature.

Here, the term "panel" refers to an object to which a film is attached, and typically refers to a vehicle license plate. Therefore, there are cases where the panel is not attached to anything. Meanwhile, there are various types to which other films may be attached first.

In the panel manufacturing process, in attaching a film to a panel based on the adhesion or adhesiveness formed on at least one side of the film or panel, attaching an adhesive film to one side of the panel, and a touch film or display film to one side of the adhesive film It is carried out including the process of attaching the

Hereinafter, the expression "adhesive" or "adhesive" is used as a concept that also includes the meaning of "adhesiveness".

In order to attach an adhesive film (including various films capable of "adhesion" such as an Optically Clear Adhesive (OCA) film, etc.), a touch film, or a display film to the panel, various film attachment devices are being developed.

For example, Korean Patent Registration No. 10-0923582 (20091019) discloses a 'polarizing film attachment device' for attaching a polarizing film to have the same curvature as glass.

However, according to the 'polarizing film attachment device' published in Korean Patent Registration No. 10-0923582, there is a problem in that the edge portion sticks to the end of the attachment film before putting it on the attachment position.

In addition, the license plate has a panel made of aluminum and a film printed with a pattern or logo is attached to the front of the panel.

As shown in FIG. 1 , in the prior art, the panel 1 moving by being released from the supply roll 11 moves through the lower part of the heating unit 20 , and the heating unit 20 generates heat using several electricity. The heating panel (1) is positioned above the moving panel (1), and the arrangement or form is applied differently depending on the moving form of the panel (1).

The cut part 50 is configured to cut the film panel 4 adhered by the adhesive part 40 to a set unit length.

The discharge unit 60 is configured to collect the film panel 4 cut by the cutting unit 50 for subsequent processing.

However, in the prior art, there is a problem in that bubbles are generated between the panel and the film in the process of continuously adhering the film to the continuously moving aluminum panel, causing a lifting phenomenon.

In addition, in the prior art, when air bubbles are generated between the panel and the film, when used for a long time, the film peels off the panel and the panel deteriorates.

In addition, the prior art has a problem in that when air bubbles are generated between the panel and the film, it is not possible as a product and is discarded as a defective product, resulting in loss.

For this reason, when the panel moves continuously and the film is requested, the adhesion of the adhesive layer is increased and the shape of the roller is improved so that air bubbles do not occur, so that it is possible to remove even if air bubbles are generated. There is an urgent need for an attachment device.
