Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a flexible film,

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a flexible display film adhering apparatus, and more particularly, to a flexible display film adhering apparatus which is capable of reducing the defective rate due to bubble generation or glass breakage when a film is adhered to a side surface of a glass, The present invention relates to a flexible display film laminating apparatus which has been developed in order to reduce time.

The display device has been mainly limited to TVs and monitors in the past, but the development of technology has been rapidly shifting to a flat panel display (FDP: Flat Panel Display) which is easy, thin and light in weight.

Such a flat panel display (FDP) uses a plate type glass such as a liquid crystal display (LCD), a plasma display panel (PDP), an organic electroluminescence display (OLED) Flexible flexible displays, however, can be applied to a wide range of applications beyond the conventional flat display, and therefore the industry's interest and research on flexible displays with stable lines is increasing day by day. .

Since the flexible display device is flexible, it does not refer to only bending arbitrarily, but it does not bend, but the display surface itself includes various curves other than a straight line.

In the case of such a curved display, since the installation site can be more widely applied, a variety of devices having curved display are developed in a smart phone, thereby giving a new aesthetic feeling and functionality.

However, in the process of attaching the film to the flexible display having such a curved line, there is a disadvantage in that the defective rate such as generation of bubbles and the pressure of the glass in the adhesion process is increased, and unlike the flat surface, Is consumed.

The film guide portion 3 is fixed to the upper portion of the film 200 in a convex shape with both ends of the film 200 hanging on the mounting step 34. The width of the film guide portion 3 is determined by the fourth to fifth electric cylinders 31 and 32 To the glass fixing portion 2 to be described later.

At this time, the film 200 includes a film supply block 42 that moves in conjunction with a third guide rail 41 extending in the front-rear direction on the front surface of the film crimping portion 1, And a film fixing plate 43 having a width smaller than the width of the film 200 to be supplied and having a convex shape from the left and right ends toward the center, The film supply unit 4 is provided with a film supply unit 4 for supplying a film.

When the film 200 is placed on the film fixing plate 43, the film fixing plate 43 is advanced in a state in which the film 200 is fixed by the suction force of the air adsorption holes, and when the film fixing plate 43 is positioned below the glass fixing unit 2, When the two ends of the film 200 are stuck to the seating step 34 while the distance between the film seating plates 33 of the film guide part 3 is narrowed, air suction is stopped and the film 200 is guided to the film guide part 3, So that it is positioned below the glass 100 fixed to the glass fixing part 2.

FIG. 7 is a perspective view showing a film seating unit according to an embodiment of the present invention, FIG. 8 is a side view showing the operation of the film seating unit according to an embodiment of the present invention, FIGS. 9 to 11 are views A bottom plate 11 having a pair of vertical panels 111 vertically installed on both sides of the bottom panel 11 and a guide plate 11 fixed to the top surface of the bottom panel 11, A lower inclined block 12 mounted on an upper surface of the block 121 and inclined in a forward direction and moving in the forward and backward direction by a first power cylinder 122 and a lower inclined block 12 vertically formed on the vertical panel 111 The lower inclined block 12 is mounted on the bottom surface of the lower plate 132 of the flat plate type in combination with the pair of first guide rails 131 and has an inclined surface in close contact with the inclined surface of the lower inclined block 12, In accordance with the forward and backward movement of The upper inclined block 13 and the upper end of the pressure regulating cylinder 141 mounted at the center of the upper surface of the lower table 132 are connected to the center of the bottom surface of the lower table 132 and both sides thereof are connected to the first guide rail 131 The upper table 14 includes a pair of second guide rails 142 extending upward and downward and extending in the left and right direction. The second guide rails 142 are coupled to the lower surface of the second power transmission cylinder 151 A rotary shaft 162 extending in the front and rear direction and rotated by a rotary motor 161 is mounted on the rotary table 162 and a rotary shaft 162 And a pressing roller (164) which is connected to an upper end of a pair of roll fixing brackets (163) extending to the upper portion of the film pressing unit (16);

The glass fixing block 22 to which the opposite surface to which the film 200 of the glass 100 is to be mounted is tightly fixed is located at the vertical upper portion of the film pressing device 16 And a glass fixing part (2) for fixing the flexible display film.

When the film 200 is positioned in the vertical lower part of the glass fixing part 2, the first electrodynamic cylinder 122 is actuated to raise the device in the film seating part 1, and the rotation motor 161 rotates the pressing rollers 164 Is positioned at one end of the glass 100 and the film 200 to which the glass 100 is adhered.

Thereafter, the moving table 15 moves along the second guide rail 142, and the pressing roller 164 advances the process of attaching the film 200. As shown in the figure, the glass 100 is curved The roll fixing bracket 163 can be adjusted so that the roll fixing bracket 163 can be positioned in the most effective direction for joining by using the rotation motor 161.
