BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a curved material laminating apparatus, and more particularly, to a curved laminating apparatus capable of stably bonding a flexible material to a curved surface material having curved surface and planar shape without bubbling.

A flexible material that has various elastic properties such as a film and can be variously deformed is attached to a specific material and used as an integral body in many cases. Therefore, many techniques for attaching a flexible material to a specific shape material have been developed.

In particular, in recent years, a structure in which a flexible material 2 is cemented to a curved window glass 1 having a shape as shown in Fig. 1 is mainly used for a display device including a mobile phone and a device using a touch screen parcel I started to. In this case, since the flexible material 2 is severely deformed during the attaching process, it is difficult to press the flexible material 2 against the curved surface of the curved window glass 1 with difficulty in applying a uniform pressure to all the surfaces Lt; / RTI >

Particularly, when the flexible panel or sheet is attached to the curved window glass, there is a high possibility that bubbles are generated in the curved surface portion, and the assembling force is also deteriorated. In order to solve this problem, when a flexible panel or sheet is attached to a curved window glass in a current state, a lacquering operation is performed in a vacuum state in order to prevent the occurrence of bubbles.

However, even if the laminating operation is carried out in the vacuum, it is not possible to prevent bubbles from occurring, and the cost of the equipment is increased and the process time is prolonged.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a curved material bonding apparatus capable of stably bonding a flexible material to a curved surface material having both a curved surface and a planar shape without bubbles.

According to an aspect of the present invention, there is provided a curved material cementing apparatus comprising: a mounting jig (110) for mounting a curved surface material (1) having a curved surface (1a) and a curved surface (1b) ; A cohesive roller 120 installed above the mounting jig 110 for pressing the flexible material 2 downward and fixing the flexible material 2 to the curved material 1; Roller moving means 130 coupled to the lapping roller 120 to move the lapping roller 120 vertically and horizontally; A jig driving means 140 coupled to a lower surface of the mounting jig 110 for vertically driving and rotating the mounting jig 110; The other end of the flexible material 2 is adhered to the other end of the curved material 1 from the start of the cohesion at which one end of the flexible material 2 is adhered to one end of the curved material 1 The control unit controls the roller moving unit 130 to horizontally move the lapping roller 120 horizontally at the same height until the end of the lapping process and controls the movement of the flexible material 2 and the curved surface material 120 in accordance with the horizontal movement of the lapping roller 120. [ (Not shown) for controlling the jig driving means 140 such that the curved surface material 1 meets in parallel with the flexible material 2 at the point where the curved surface material 1 is adhered.

Further, in the present invention, it is preferable that the curved material 1 is a window glass having curved surfaces on both sides or one side.

Further, in the present invention, the flexible material 2 is preferably any one selected from a flexible display panel, an OCA film, and an ITO film.

According to the present invention, there is an advantage that a flexible material can be adhered to a curved material without generating bubbles without using a vacuum lacquer, and the overall manufacturing cost of the apparatus is very low.

Hereinafter, a specific embodiment of the present invention will be described in detail with reference to the accompanying drawings.

2, the curved surface material sticking apparatus 100 according to the present embodiment includes a mounting jig 110, a lapping roller 120, a roller moving means 130, a jig driving means 140, (Not shown).

First, the mounting jig is a component to be mounted so that the joint surface of the curved surface material 1 having both the curved surface 1a and the flat surface 1b is exposed. Here, the curved surface material 1 may be a window glass having curved surfaces on both sides or one side thereof. Therefore, as shown in FIG. 2, the mounting jig 110 is formed with a mounting groove having a shape corresponding to the shape of the curved surface material 1, and the mounted curved surface material can be fixed so as not to move during the cementing process Vacuum suction means (not shown in the drawing), and the like.

2, the laminating roller 120 is installed on the upper side of the mounting jig 110 and presses the flexible material 2 downward so as to be fixed to the curved surface material 1 Element. That is, the lapping roller 120 presses the upper surface of the flexible material 2 whose both ends are gripped by the material gripping means 152 and 154 in the downward direction, thereby moving the flexible material 2 to the curved material 1 ) Are sequentially attached to the cemented surface.

Here, the flexible material 2 may be any one selected from a flexible display panel, an OCA film, and an ITO film.

2, the roller moving unit 130 is a component that is coupled to the lapping roller 120 to move the lapping roller 120 in the vertical and horizontal directions. That is, as shown in FIG. 3, the roller moving unit 130 moves the vertical and horizontal directions of the lapping roller 120 in accordance with the change of the pressing position in accordance with the rotational driving of the mounting jig 110 in the process of attaching the flexible material. To move the position. Accordingly, the roller moving unit 130 may include a horizontal moving unit 132 and a vertical moving unit 134.

Next, the jig driving means 140 is coupled to the lower surface of the mounting jig 110, and is a component for vertically driving and rotating the mounting jig 110. That is, the jig driving means 140 is arranged so that the joint portion of the joint surface of the curved surface material 1 mounted on the mounting groove has an angle suitable for the approach form of the flexible material 2, Thereby rotating the mounting jig 110 at various angles.

Also, the mounting jig 110 is vertically moved up and down so that the bonded portion of the curved surface material 2 mounted on the mounting jig 110 is kept at the same height as possible. Therefore, the jig driving unit 140 may include a turning unit 142 and an elevating unit 144, as shown in FIG.
