Description

Lamination device {LAMINATION APPARATUS}

The present invention relates to a lamination apparatus, and more particularly, to a lamination apparatus for accurately and precisely laminating a film on a glass having a three-dimensional curved surface.

Currently, in the automobile market, an 850 mm (30 inch) display placed on the driver's seat side and a 1,500 mm (60 inch) display covering the front are used in the automobile market, and a free-form surface is preferred over a flat surface.

Such displays for automobiles are mainly applied to the cluster and center information displays (CIDs), but plastic products have been used due to limitations in molding technology.

However, conventional plastic displays for automobiles have problems in that yellowing occurs due to UV rays and the like and distortion of the screen due to hardening, as well as being vulnerable to chemicals for cleaning the interior of the vehicle.

In addition, in recent years, as a trend to apply a digital instrument panel rather than an analog instrument panel, a clean screen is more important, and there is a difficulty in overcoming the above-mentioned technical limitations with the conventional plastic material.

For this reason, recently, glass with good touch feeling, strong UV resistance, chemical strengthening, and excellent surface light properties has been widely adopted and used as a display material.

However, the glass (glass) is easily damaged, such as a risk exists. Accordingly, for the purpose of solving these shortcomings, the scattering prevention film is necessarily laminated.

Although such lamination treatment is performed manually, there is a disadvantage that a uniform laminating treatment is impossible and a problem of lowering productivity. work is possible

At this time, the conventional laminating roller has a configuration having a flat roller arrangement.

However, as described above, as described above, a free-form surface is preferred over a flat surface of the current interior display for a vehicle, and there is a problem in that a lamination operation cannot be performed on a free-form surface with a conventional lamination apparatus using a flat roller.

In this case, the free-form surface may be referred to as a three-dimensional curved surface, which means a curved surface having various curvatures rather than a simple curved surface having a constant curvature.

On the other hand, in relation to the prior art literature, reference may be made to Korean Patent Publication No. 10-2015-0105887, which is "a base frame having a mounting space formed at the upper part; it is rotatably mounted in the mounting space of the base frame and has an outer surface. A rotating drum in which a vacuum adsorption unit for fixing the ITO sensor is formed; a rotating unit accommodated in the base frame and rotating the rotating drum; an ITO sensor accommodated in the base frame and located in the vacuum adsorption unit A device for lamination of a curved touch screen panel comprising: a vacuum means for adsorbing; is starting

As such, the prior art literature mainly discloses a lamination device for a curved touch screen panel, but it will be said that there is a difference in technical configuration from the present invention proposed below, and the instrument panel (Cluster) unit and information guide display (CID) : It was not easy to find the proposed technology of lamination device for automobile display manufacturing such as Center Information Display).
