BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a lapping device for a curved cover glass using roller pressing, and more particularly, to a lapping device for a curved cover glass by roller pressing, And more particularly, to a cohesive device for a curved cover glass using a roller pressing method in which a sensor film is pressed against an inner surface of a curved cover glass by a roller.
2. Description of the Related Art In general, a touch screen panel is an input device that replaces a keyboard and a mouse, and is a display device in which a user touches a touch screen panel installed on a display terminal with a hand or a touch pen to input desired information.
The touch screen panel is an ideal device that can perform intuitive work in a GUI (Graphic User Interface) environment and is widely used in computer-based training, simulation application, office automation application, education application, and game application. In recent years, a touch screen panel is widely used in various communication apparatuses to widen the display area while reducing the weight and thickness of the terminal.
In recent years, a curved display screen has appeared rather than a flat surface, so that a curved window has to be fitted to the curved surface of the display, thus requiring a curved touch screen panel.

However, in order to attach the curved sheet in this manner, the diameter of the roller must be smaller than the radius of curvature of the curved portion. Otherwise, the surface of the roller is not completely in contact with the curved surface, and the crimping is not correct. However, the cover glass of recent products has a very small radius of curvature of the curved surface portion, which requires a small-sized roller. However, the method of pressing the film slowly while releasing the film with a small-sized roller has a problem in implementation.
According to an aspect of the present invention, there is provided a sensor film comprising two rollers for pressing and curving an edge of a sensor film to form a curved surface, and a sensor film formed by a curved surface is attached to the inner surface of the curved cover glass, And an object of the present invention is to provide a cohesive device for a curved cover glass using roller pressing for applying pressure while rotating a cover glass.
Further, the present invention provides a roller pressing device for rotating a cover glass and a sensor film while gripping a cover glass and a sensor film between a roller having a large outer diameter and a roller having a small inner diameter, And to provide a lapping device for a curved cover glass using the same.
Further, the present invention provides a cohesive device for a curved cover glass using roller pressing, which prevents the cover glass rotated on the opposite side from contacting the attracting plate by rotating the opposite end of the attracting plate by a predetermined angle when the cover glass is rotated about 180 degrees .
In order to solve the above-described problems, the present invention, which is devised to solve the above-described problems, is an apparatus for pressing a

Claims (2)
A glass attracting plate (102) for attracting the outer surface of the cover glass (60) by a vacuum suction force or an electrostatic force;
The center axis is located at one side edge of the glass attracting plate 102 in a state where the central axis is parallel to the plane of the glass attracting plate 102 and the center axis is moved at the beginning of the joining process to press the sensor film 70, A first roller 104 that presses an edge of the first roller 70 to form a curved surface;
A film attracting plate 106 installed at a position opposite to an inner side surface of the cover glass 60 adsorbed on the glass attracting plate 102 to attract the sensor film 70;
The film is smaller than the first roller 104 in diameter and is provided at a side of the edge of the film attracting plate 106 that is closer to the first roller 104, And a second roller (108) having a radius that is relatively smaller than a curvature radius of the curved portion of the cover glass (60)
While the cover glass 60 and the sensor film 70 are rotated while being pressed by the first roller 104 and the second roller 108, the film attracting plate 106 gradually removes the attracting force, So as to allow the film (70) to slide from the film suction plate (106) to the inner side of the cover glass (60).
