However, the above-described techniques produce a curved display device by attaching a roller or a window and each jig or the like on which the panel is seated to join the window and the panel, but if the shape of the window is such that the surface is largely bent, There is a fatal problem in that an expensive dedicated cocoon must be purchased separately because the cocoon must be made using only a dedicated cocoon matching the shape of the window.
SUMMARY OF THE INVENTION The present invention has been made in order to solve the above-mentioned problems and technical prejudices, and it is an object of the present invention to provide a method of manufacturing a flexible window, which has various shapes, i.e., a flat shape, a large bend surface, or at least one curved edge, And it is an object of the present invention to provide a window laminating apparatus and a laminating method using the same.
According to an aspect of the present invention, there is provided a window sticking apparatus comprising: a window elevator including a jig having a support groove for supporting the window; A panel seating part disposed below the window lifting part and on which a panel attached to the window is seated; The panel is placed on one side of the panel seating portion and the roller is brought into contact with the center portion of the bottom surface of the panel that is seated on the panel seating portion and the panel is moved by the horizontal movement and the tilting according to the shape of the window, A joining portion for joining to the window; And a controller for controlling a pressure applied to the roller according to a section in which the roller is located.
At this time, the panel seating portion includes a plate-shaped bracket; The panel is rotatably coupled to the bracket at a lower side in the longitudinal direction while maintaining a spaced width at which the panel can be seated, and an extension piece having a predetermined length having a seating groove in which the panel is seated, A pair of pivots; And an elastic member connected to the bracket and the pair of pivotal pieces, respectively, to apply elasticity to return to the original position when the pivotal pieces are rotated.
The joining portion may include a horizontally moving member that horizontally moves in a direction intersecting with the window elevating portion on a horizontal keit tree; A speed reducer provided on one side of the horizontally moving member; Wherein the roller is connected to the speed reducer and applies pressure to the roller according to a section in which the roller is positioned while the roller is raised when the panel is attached, A pressing unit for tilting the roller; And a push cam projecting from the plate-like support piece provided on the other side of the horizontally moving member to the space between the pair of turn pieces of the panel mount portion and pushing the rotary piece to rotate when horizontally moving the horizontal movement member Do.
The pressing unit may include a cam follower disposed on one side of the horizontally moving member in a state of being connected to the speed reducer; A plate-like tilting plate extending a predetermined length from the cam follower; A supporting member arranged on the upper surface of the tilting plate so that the roller having a predetermined length is rotatably disposed on the upper portion and the roller is positioned between the pair of extending pieces; And an elevating shaft penetrating through the tilting plate to engage with the longitudinal center of the supporting member to lift the supporting member so that the roller is positioned in contact with the panel, And an elevating cylinder for adjusting a pressure applied to the roller according to the section.
In addition, it is preferable that a guide member disposed on the bottom surface of the tilting plate and protruding and retracted from the supporting member is provided on both sides of the lifting cylinder so that the supporting member lifted and lowered by the lifting cylinder is kept horizontal.
It is preferable that the surfaces of the respective seating grooves of the pair of pivoting pieces are formed into a curved surface that gradually increases toward the upper portion in the direction facing each other.
When the pivotal piece pivoted by the push cam is returned to its original position, the bracket is provided with a pair of pivots, each pivoted to a position spaced apart from the pivoted piece, It is preferable that a pair of stoppers each supporting one face is disposed between the pair of pivotal pieces.
The window elevator includes a vertical gantry installed upright; And a vertical moving member having one side thereof movably installed in the vertical gantry and the other side of which is coupled with the jig such that the support groove, on which the window is supported, faces the lower surface.
When the panel is attached to a window having curved edges on both sides of the panel, the controller applies pressure to the center of the panel at a pressure P1 at which the roller contacts the center, If the pressure of the losing roller is P2 and the pressure applied to the edge section is P3, it is preferable to control the pressure applied to the roller to satisfy P1 < P2 < P3.
At this time, the pressure range of P1 is 0.048 to 0.11 (MPa), the pressure range of P2 is 0.19 to 0.31 (MPa), and the pressure range of P3 is 0.38 to 0.52 (MPa).
In the meantime, the joining method of the present invention comprises: (S10) lowering the jig supporting the window to a set position; Pressing the center of the panel by raising the roller so that the panel is brought into contact with the window (S20); A step (S30) of pressing the roller in contact with the central portion of the panel while moving the roller in a horizontal section in one direction to join the horizontal section in one direction of the panel with the window; (S40) a step of pressing the roller while tilting the roller from a point where the window edge section starts, to join the edge section of the panel with the window (S40); (S50) moving the roller in the other direction to pressurize the horizontal section in the other direction while adhering the one-direction horizontal section of the panel to the window; (S60) of attaching the edge section of the panel to the window by pressing the roller while tilting the roller from the position where the window edge section of the other direction starts.
According to the window sticking apparatus of the present invention having the above-described structure and the sticking method using the window sticking apparatus of the present invention, when the shape of the flexible window to be cemented is variously shaped, that is, flat, bended greatly or has at least one curved edge, Regardless of the type, there is an excellent effect in stably bonding the panel to the window.
In addition, since windows having various shapes can be attached and bonded through the laminating apparatus of the present invention, it is economically advantageous to reduce the cost of purchasing a dedicated laminator corresponding to the window shape.
Also, since the initial adhesion is made at the center of the panel, and the pressure applied to the roller is differently set according to the zone in which the roller travels, stemming is fundamentally blocked, thereby improving the reliability of the cemented window.
