Description

A tilting function-imparting attachment of a head unit for a curved panel flexible material bonding device and a curved panel flexible material bonding device including the attachment}

The present invention relates to an apparatus for bonding a flexible material such as a film to a curved panel, and more specifically, to a curved panel as well as a flat part of a curved panel having one or more sides formed in a curved surface, as well as a flexible material such as a film. In the head unit constituting the curved panel flexible material bonding device, the head unit for the curved panel flexible material bonding device can automatically maintain the level of the curved panel surface when the pressure roller part moves up and down vertically to the ground. It relates to a tilting function giving attachment and a curved panel flexible material bonding device including the attachment.

A display represents an electrical signal output from an electronic device as image information, and collectively refers to an image display device that implements various visual information that humans can see on a screen. Such a display is evolving from a flat panel display, which was composed of flat surfaces on all sides, to a flexible display that can transform its shape, such as by folding or bending. As shown in , a curved display in which a flexible material such as a film is bonded to a curved panel having at least one side surface formed as a curved surface is used.

It is relatively easy to attach a film to a flat panel in a flat display, but in case of attaching to a curved panel of a curved display, it is difficult to apply uniform pressure to all surfaces. It is very difficult to attach.

In order to solve this problem, when a flexible panel or sheet is bonded to a curved window glass, the bonding operation is performed in a vacuum state to prevent the generation of bubbles. Another problem, such as a high unit price and a long process time, also occurs.

As a result of a number of studies to develop a technology that can precisely bond flexible materials such as films on not only the flat part of the curved panel but also the curved part without air bubbles or wrinkles, the present inventor has applied a flexible material to the curved panel to the flat surface of the curved panel. A flexible material bonding device with a structure that can be attached by dividing into areas and curved areas was developed, and the device and a flexible material bonding method using the device were applied for and registered as Patent No. 10-2209125 (hereinafter referred to as "prior patent technology"). have been registered

By the way, as shown in Figures 1a and 1b, the prior patent technology is parallel to the curved panel (PANEL) when the pressure roller part, that is, the main pressure part 212 and the auxiliary pressure part 213 descend, and the flat part with constant pressure In order to press and bond the curved surface part, a leveling unit is formed on the fixed plate part, and an adjuster (parts such as micrometers and adjusting bolts) is installed. This is difficult and therefore requires a lot of time for flat setting.

In other words, for level setting, ① Lowering the pressure roller ② UNCLAMP the fixing bolt of the pressure roller ③ Finely adjust with the adjuster (micrometer & adjustment bolt) of the leveling unit ④ CLAMP the fixing bolt of the pressure roller ⑤ Raise the pressure roller ⑥ Standby because it had to go through a process called

Therefore, it is necessary to develop a head unit having a new structure that does not require a separate leveling of the pressure roller unit, that is, flatness setting, or a flatness setting time can be easily performed.
