Abstract

The present invention relates to the best means capable of effectively attaching a thin film, such as a protection film, a touch film, and so on, to a curved glass which is curved with a predetermined curvature (R) in a display panel (a liquid crystal display (LCD), a personal digital assistant (PDA), a plasma display panel (PAP), or the like) of an electronic device (a mobile phone, a television, an electronic dictionary, or the like) to exhibit not only excellent aesthetic quality and design, but also a flexible functional characteristic, thereby attracting attention as a next-generation promising product. In other words, according to the present invention, a film adhesion apparatus (A) for an overall curved glass is configured such that a film (F) (a protection film, a transparent conductive touch film, or the like) is effectively attached to an inner surface (a lower surface) or an outer surface (an upper surface) of an overall curved panel (P) having a predetermined curvature (R) on the whole. The film adhesion apparatus (A) is provided at a lower portion thereof with a curved panel mount (100). The curved part panel (100) is set with the overall curved panel (P). The film adhesion apparatus (A) is provided at an upper portion thereof with a drum type film adhesion device (200) corresponding to the curved part panel (100).

Description

TECHNICAL FIELD The present invention relates to a method for attaching a film of a full-curvature type glass,

The present invention can flexibly display a functional characteristic such as a wrist cell phone as well as an excellent sense of newness and design by curving a certain R (curvature) among display panels (LCD, PDA, PAP etc.) It is the best way to effectively attach protective films, touch films, and other thin films to a curvature glass that has been attracting attention as a next-generation promising product.

The outer surface of the display panel (LCD, PDA, PAP, etc.) is usually made of a thin film made of a thin layer of microlenses for the purpose of safely and easily protecting the surface of the panel or preventing fingerprints, , FRP or the like,

It has become common to attach a transparent conductive film having indium tin oxide (ITO) formed thereon by sputtering so that the inner surface of the touch panel can recognize the touch and act as a sensor.

Recently, the trend of the touch panel is formed by forming a curvature only at the sides of the left and right edges for the purpose of enhancing the visual immersion feeling and improving the appearance, design and merchandise of the user according to the preference of the user, A " curvature-type touch panel", in which curvature of R is uniformly formed over the entire panel as shown in the drawing together with the curved touch panel, and a wider and more sophisticated design and a flexible function can be produced together, has already been commercialized There is a bar.

Particularly, the full curvature type touch panel is mainly applied to a wristwatch-type smartphone (a smartphone that is wound around the wrist) that requires a flexible curvature so far. In the future, it is expected that it will gradually expand to use for general purpose mobile phone for the purpose of designing unique, improving the merchantability, and diversifying the functionality.

On the other hand, prior art documents for attaching a film to a pop panel are disclosed in Patent Document 10-1159028 (a method and apparatus for attaching a display film for an electronic device) registered by the applicant of the present application, and Patent Document 10-1316640 A slide-type display panel protective film attaching device using warpage) and a patent pending 10-2014-0150190 (film sticking device of curved glass) have already been known.

However, the preceding documents of the above-mentioned Patent No. 10-1159028 and No. 10-1316640 are apparatuses capable of attaching the film only to a simple form of a panel (glass) in a horizontal or flat form,

In the case of 10-2014-0150190, which is currently filed, it is an apparatus which enables easy attachment of a film to a curved panel bent at a certain R on both edges of the panel,

This is because, as described above, the present invention is limited to a panel-dedicated film adhering device in which a curvature is partially formed on one side or both sides of a panel,

There has been a problem in that it is practically impossible to precisely adhere the film to the entire curvature type panel having a certain R throughout the panel.

Since the entire curvature type touch panel is formed with a curvature as a whole, when a curved panel exclusive film attaching device having a constant curvature is formed on both side edges, moving rollers and deflection of the elastic thin plate to attach the film to the curvature surface thereof It is difficult to attach the film to the film with high efficiency because it is very complicated and complicated because additional separate devices need to be additionally installed in order to avoid interference with the elastic thin plate.

Patent Registration No. 10-1159028, Patent Registration No. 10-1316640

Therefore, in the present invention, it is possible to precisely attach the film to the entire curvature type panel panel, which is not possible with the conventional technology, and thus it is possible to attach a wristwatch type smartphone or a touch mobile phone with a large bend The present invention has been accomplished on the basis of providing a new film adhering method and apparatus which can be applied to a film.

The present invention for achieving the above object is to provide a film (protective film, transparent conductive touch film, etc.) on an inner surface (bottom surface) or an outer surface (upper surface) of a full curvature type panel P having a constant R (F) can be effectively attached to the curved panel mounting device (A), wherein the curved panel mounting platform (100) with the full curvature type panel (P) At the upper portion corresponding to the curved panel mounting table 100, rolling-type drums are mounted on the curved panel (P) set on the curved panel mounting table 100 at regular intervals, Type film adhering device 200 for easily attaching various types of thin films F that can be attached to the panel.

The apparatus for attaching a film of a full-curvilinear panel according to the present invention, which can be configured as described above, is characterized in that the rolling drum of the drum-type film-attaching apparatus 200 is closely contacted with R (curvature) It is possible to attach a more effective and precise film (a variety of thin films F that can be attached to an electronic device panel), which is a useful invention that can greatly contribute to enhancement of the merchantability and quality of a full curvature panel.
