[0004] Such a curved display can be bonded to a window by coating an optical clear resin (OCR) on the entire surface of the panel.

[0005] However, the panel and the window are bonded together when the optically transparent adhesive is in a pseudo-cured state, so the bonding force is not sufficient. Therefore, there is a problem of separation of the curved surface portion of the window and the panel during the manufacturing operation. Summary of the invention

[0040] Hereinafter, the embodiments will be described in detail with reference to the accompanying drawings. Regardless of the figure numerals, the same or corresponding components are given the same reference numerals, and repeated descriptions are omitted.

[0041] Figure 1 is a perspective view showing a fixing module and a pressurizing module according to an embodiment of the present invention, Figure 2 This is a conceptual diagram of a fixed module.

[0042] refer to Figure 1 and Figure 2 The laminating device in the embodiment includes a fixing module 130 for fixing the window 11, and a pressurizing module 120 for pressing the panel 13 to the window 11.

[0043] The window 11 may be a protective glass of a mobile phone. The side 11a of the window 11 may be curved. The area with the curvature may be used as an auxiliary display area. However, the present invention is not limited thereto, and the side 11a may be curved for other purposes.

[0044] The side surface 13a of the panel 13 may also be formed with a curvature so as to correspond to the side surface 11a of the window 11. In addition, the window 11 and the panel 13 may be fixed by an adhesive layer 12. The panel 13 may be a display panel and / or a touch panel, but is not limited thereto.

[0045] The adhesive layer 12 is formed on the entire surface of the panel 13. By forming the adhesive layer 12 on the entire surface of the panel 13, a gap between the adhesive layer 12 and the panel 13 can be minimized, thereby reducing light reflectivity.

[0046] The adhesive layer 12 may be a variety of resins that are cured under the action of ultraviolet rays. For example, the adhesive layer 12 may be a resin such as acrylic, but is not limited thereto, and may be a variety of resins that are cured under the action of ultraviolet rays. For example, a silicone resin or a polyurethane resin may also be selected.

[0047] The adhesive layer 12 may be pre-coated on the panel 13 or the window 11. Also, there is no limitation on the method of coating the adhesive layer 12 on the panel 13 or the window 11. For example, the adhesive layer 12 may be formed on the panel 13 with a uniform thickness or in a 3D shape using inkjet printing technology.

[0048] The first pseudo-curing may be performed when the adhesive layer 12 is applied to the panel 13 or the window 11. Pseudo-curing may be defined as a state in which the resin is not completely cured during the curing process. For example, the first pseudo-curing may be a state in which the resin is 60% to 80% cured based on 100% complete curing.

[0049] The fixing module 130 can perform a second temporary curing of the adhesive layer by irradiating ultraviolet rays when the panel 13 is bonded to the window 11. The second temporary curing can be defined as a state in which the curing degree is higher than the curing degree of the first temporary curing and lower than the curing degree of the complete curing. At this time, temporary curing can improve the bonding force to prevent the window 11 and the panel 13 from being separated and can also remove bubbles. This is because if the adhesive layer is completely cured, the bubbles inside cannot be removed.

[0050] Based on this structure, the adhesion between the window 11 and the panel 13 is improved, thereby improving the problem of the panel 13 being peeled off before being completely cured.

[0051] For the fixing module 130, a circuit board 135 is provided on the fixing block 131, and a plurality of light emitting elements 133 may be provided on the circuit board 135. The plurality of light emitting elements 133 may be respectively provided in the ultraviolet irradiation channels 134 formed in the fixing block 131, but the present invention is not limited thereto. For example, the light emitting elements 133 and the fixing block 131 may be provided in a manner of being spaced apart by a predetermined interval, and a diffusion film (not shown) or the like may be provided therebetween.

[0052] The ultraviolet light emitting element 133 is arranged in the ultraviolet irradiation channel 134 and can irradiate ultraviolet light to the window 11. The ultraviolet light emitting element 133 can be an ultraviolet light emitting diode or an ultraviolet lamp. At this time, a light-transmitting component (such as quartz) capable of transmitting ultraviolet light is arranged on the fixing surface 130-1.

[0053] The plurality of ultraviolet light emitting elements 133 may include a plurality of first ultraviolet light emitting elements 133 having a first light emitting wavelength, a plurality of second ultraviolet light emitting elements 133 having a second light emitting wavelength, and a plurality of third ultraviolet light emitting elements 133 having a third light emitting wavelength.

[0054] The first light emitting wavelength may be 300nm to 320nm, the second light emitting wavelength may be 355nm to 375nm, and the third light emitting wavelength may be 395nm to 415nm. Depending on the type of resin, the wavelength for accelerating curing is also different, so multiple wavelengths can be selectively irradiated or multiple wavelengths can be irradiated simultaneously to accelerate the curing of the resin.

[0055] The power supply unit 220 may apply power to the plurality of ultraviolet light emitting elements 133. The power supply unit 220 may apply power to the plurality of ultraviolet light emitting elements 133 as a whole, or may apply power sequentially.

[0056] At this time, an illuminance sensor (not shown) may measure the illuminance of light emitted from the plurality of ultraviolet light emitting elements 133. Therefore, when the illuminance of light emitted from some ultraviolet light emitting elements 133 decreases, it may be determined as defective and a replacement alarm may be output.

[0057] When 300 determines that the illumination of some ultraviolet light emitting elements 133 is low, the control unit can increase the current value of the corresponding light emitting element 133 to maintain the overall illumination constant. In addition, when the temperature of the fixing module 130 rises sharply through the temperature sensor (not shown), the control unit 300 can output a stop operation alarm to the outside and execute a protection program for the safety of the light emitting element. The protection program for safety can be, for example, an algorithm for forcing the circulation of cooling water or prohibiting re-operation within a certain period of time. In addition, the control unit 300 can control each component to operate the laminating device.

[0058] Figure 3 is a diagram showing a process of bringing a portion of the panel into contact with the window, Figure 4 is a diagram showing the process of bonding the entire panel to the window, Figure 5 The figure shows the detection unit for detecting whether the window and the panel are aligned.

[0059] refer to Figure 3 , the window 11 can be fixed to the fixing surface 130-1 of the fixing module 130. Air is sucked into the suction device 210 through a plurality of suction channels 132 formed in the fixing block 131, so that the window 11 can be firmly fixed to the fixing surface 130-1 of the fixing block 131. However, the fixing method is not limited thereto, and a mechanical fixing structure other than the suction channel (such as a fixing clamp) may also be provided.

[0060] The panel clamp 140 can pressurize the side of the panel 13 so that the panel 13 is bent in a convex manner toward the window 11. At this time, the panel 13 can be bent only by the panel clamp 140, or the panel clamp 140 can bend the panel 13 while pushing the pressure pad upward, thereby bending the panel 13.

[0061] refer to Figure 4 As the pressure pad 121 of the pressure module rises, the protruding portion of the panel 13 can come into contact with the window 11. If the window 11 and the panel 13 come into contact as a whole at the beginning, bubbles will be generated. Therefore, at the initial stage of contact, the protruding portion of the panel 13 can come into contact with the window 11 first, which is conducive to suppressing the generation of bubbles.

[0062] refer to Figure 5 As the pressure pad 121 is pressed, the window 11 and the panel 13 can be bonded as a whole. Since the pressure pad 121 is pressed while the protruding portion of the panel 13 is in contact with the window 11, the air between the window 11 and the panel 13 is discharged to both sides based on the protruding portion of the panel 13, thereby effectively removing bubbles.

[0063] Since the pressure pad 121 is pressed in such a way that the window 11 and the panel 13 can be integrally bonded, the curved surface portion of the window 11 and the curved surface portion of the panel 13 can also be pressed. However, if the adhesive force of the adhesive layer 12 is not sufficient, the curved surface portion of the window 11 and the curved surface portion of the panel 13 will peel off again.

[0064] Therefore, in the embodiment, after the window 11 and the panel 13 are bonded as a whole under the action of the pressure pad 121, the adhesive layer 12 can be pseudo-cured for the second time by irradiating ultraviolet rays through the ultraviolet light emitting element 133. As a result, the adhesive force of the adhesive layer 12 is increased, and the window 11 and the panel 13 can be fully fixed without peeling. In this way, the problem of peeling of the window 11 and the panel 13 before the adhesive layer 12 is completely cured can be solved. At this time, for the adhesive layer 12, the second pseudo-curing can be performed on the entire area, or the second pseudo-curing can be performed only on a part (such as the curved surface area).

[0065] For example, the second false curing can be defined as: based on 100% curing, it is in a curing state of 81% to 98%. Therefore, the curing degree of the second false curing can be 101% to 141% of the curing degree of the first false curing. At this time, the false curing can improve the bonding force to prevent the window 11 and the panel 13 from being separated, and can also remove bubbles. This is because if the adhesive layer is completely cured, the bubbles inside cannot be removed.

[0066] When the window 11 and the panel 13 are bonded, the assembly of the window and the panel can be transferred by an additional transfer component (such as a robot arm) and a bubble removal process is performed. Since the adhesive layer 12 is still in the pseudo-curing step, the bubble removal process can be used to remove the fine bubbles remaining inside. In this way, the light reflectivity and light extraction efficiency can be improved. The bubble removal process can adopt various known methods.

[0067] Afterwards, when it is determined that the window 11 and the panel 13 have been aligned and bonded and the bubbles have been removed, the adhesive layer 12 can be completely cured.

[0068] Figure 6 This is a top view of the fixed module. Figure 7 2 is a diagram showing a process of adjusting the area by moving the fixed module left and right.

[0069] refer to Figure 6 , the fixing module 130 may include a first fixing module 131a and a second fixing module 131b that are separable from each other, and a driving unit 36. The window 11 may have various widths according to the type of display. In the embodiment, since the window 11 has a curvature, it is necessary to have a fixing module 130 that is suitable for the curvature. In this case, the cost of manufacturing a plurality of fixing modules 130 increases, and there is the trouble of replacing the fixing module 130 whenever the window 11 model is replaced.

[0070] In the embodiment, since the first fixing module 131a and the second fixing module 131b are spaced apart in the first direction, an area for fixing the window 11 can be adjusted. In this case, the first direction may be a width direction of the window.

[0071] The first fixing module 131 a may include a plurality of protrusions 136 a protruding in a first direction (X1 axis direction) facing the second fixing module 131 b , and a plurality of recesses 136 b recessed in a direction (X2 axis direction) opposite to the first direction.

[0072] The second fixing module 131 b may include a plurality of protrusions 136 c protruding in a direction (X2-axis direction) opposite to the first direction, and a plurality of recesses 136 d recessed in the first direction (X1-axis direction).

[0073] According to this structure, since the first fixing module 131a and the second fixing module 131b are formed in a zigzag shape, even if the first fixing module 131a and the second fixing module 131b are separated by the first interval d1, the reduction in light uniformity can be minimized. If the first fixing module 131a and the second fixing module 131b are formed in a rectangular shape, light is hardly irradiated in the middle portion when they are separated from each other, so the light uniformity is reduced. Therefore, the problem of partial area not being cured may occur.

[0074] When the first fixing module 131a is spaced apart from the second fixing module 131b by a first interval d1, a spacing portion G1 is formed between the protrusion 136a of the first fixing module 131a and the recess 136d of the second fixing module 131b, and a spacing portion G1 is formed between the recess 136b of the first fixing module 131a and the protrusion 136c of the second fixing module 131b.

[0075] Figure 8 is a first variant of the fixed module, Fig. 9 is a second variant of the fixed module, Fig.10 This is a third variation of the fixing module.

[0076] refer to Figure 8The fixing module 130 may include a first fixing block 131a and a second fixing block 131b that may be spaced apart from each other, a first circuit board 135a disposed on the first fixing block 131a, and a second circuit board 135b disposed on the second fixing block 131b. When the first fixing block 131a is spaced apart from the second fixing block 131b, the first circuit board 135a and the second circuit board 135b may also be spaced apart.

[0077] At this time, the third circuit board 135c and the light emitting element 133-1 may be disposed on the side of the first fixing block 131a, and the fourth circuit board 135d and the light emitting element 133-1 may be disposed on the side of the second fixing block 131b. According to this structure, light can be uniformly irradiated to the curved surface area of ​​the window.

[0078] refer to Fig. 9 , a circuit board 135 can be set on the first fixed block 131a and the second fixed block 131b of the fixed module 130 that can transmit ultraviolet rays. For example, the first fixed block 131a and the second fixed block 131b can be quartz plates, and any material that can transmit ultraviolet rays can be used. According to this structure, the channel for irradiating ultraviolet rays can be omitted, so it has the advantage of simplifying the production. In addition, as the light is reflected and refracted in the first fixed block 131a and the second fixed block 131b, the ultraviolet light can be uniformly irradiated onto the fixed surface 130-1. At this time, although not shown in the figure, an intake channel can be set in the fixed block 131 in advance.

[0079] When the first fixing block 131a is spaced apart from the second fixing block 131b, the first light emitting element 133a disposed in the spacing area d1 of the first fixing block 131a and the second fixing block 131b among the plurality of light emitting elements 133 can still irradiate the window with ultraviolet light. Therefore, some areas of the window disposed in the spacing area d1 can be completely cured.

[0080] Therefore, in an embodiment, when the first fixing block 131a is spaced apart from the second fixing block 131b, the luminous intensity of the first light emitting element 133a can be controlled to be lower than the luminous intensity of the other light emitting elements 133. When the first fixing block 131a is not separated from the second fixing block 131b, the luminous intensity of the first light emitting element 133a can be controlled to be the same as the luminous intensity of the other light emitting elements 133.

[0081] According to this structure, some areas of the window disposed in the spacing area d1 may also be provisionally cured for the second time. However, the present invention is not limited thereto, and an additional light shielding member may also be disposed in the spacing area d1.

[0082] refer to Fig.10The fixing blocks can be divided into a first fixing block 131a, a second fixing block 131b and a third fixing block 131c. That is, the fixing blocks can be divided into various numbers to adjust the area.

[0083] The fixing block 131 may include a first area EA corresponding to the curved area 130-1b of the fixing surface, and a second area PA corresponding to the plane area 130-1a of the fixing surface. At this time, the spacing d12 between the light-emitting elements 133 arranged in the first area EA is denser than the spacing d11 between the light-emitting elements arranged in the second area PA. Since it is relatively difficult to irradiate the curved area of ​​the window (or the curved area of ​​the fixing surface) with uniform light, the amount of light on the outer side of the circuit board 135 is relatively small. Therefore, as compensation, it is best to arrange the light-emitting elements 133 more densely. As a result, the curved area of ​​the window can also be irradiated with uniform ultraviolet light, so that a uniform second false curing can be achieved. At this time, a reflective film 137 can be formed on the outer side and bottom surface of the fixing block to prevent the irradiated light from emitting to the surface other than the fixing surface. The reflective film 137 can be an aluminum reflective film that reflects ultraviolet light.

[0084] Fig.11 is a cross-sectional view of a pressure pad. Fig.12 is a first variation of the pressure pad, Fig.13 is a second variation of the pressure pad, Fig.14 is a third variation of the pressure pad, Fig.15 is a diagram showing a process of dividing a support portion to adjust an area, Fig.16 is a diagram showing a process in which the fixing module and the pressure pad are respectively divided, Fig.17 yes Fig.16 A variation of .

[0085] refer to Fig.11 , the pressurizing module 120 may include a pressurizing pad 121 for pressing the pad, and a support portion 127 for fixing the pressurizing pad 121. The upper surface 121a of the pressurizing pad 121 may have a curvature. The curvature of the upper surface 121a may be substantially equal to or less than the curvature of the curved panel 13. In addition, when the pressurizing pad 121 is pressed, the area of ​​the upper surface 121a may be greater than the width and / or length of the panel 13.

[0086] A plurality of volume adjustment members 122a to 122e may be provided inside the pressure pad 121. The inside of the volume adjustment members 122a to 122e may be an air gap (AirGaP). In this case, the volume adjustment member may be inserted into the air gap.

[0087] The pressure pad 121 is a process means in which the directionality of contraction and expansion is very important. A driving shaft 128a, 128b or a fixing pin may be inserted to control the directionality and expansion amount of the contraction and expansion of the pressure pad 121.

[0088] However, the present invention is not limited thereto, and the volume adjusting components 122a to 122e may have a shape into which a preset elastic component is inserted. In this case, the elastic modulus of the elastic component inserted into each of the volume adjusting components 122a to 122e may be different.

[0089] In the embodiment, after the window and the panel come into contact, it is necessary to control the pressure pad 121 to be quick so that the window and the panel are bonded as a whole. Therefore, it is necessary to control the upper part to be relatively quick. Therefore, the volume adjustment components 122a to 122e can be set so that the first volume adjustment component 122c set in the central area is deployed most quickly when pressurized. When the volume adjustment components 122a to 122e are all gaps, the diameter of the first volume adjustment component 122c can be set to the maximum for easy deployment.

[0090] refer to Fig.12 In this case, an ultrasonic generator 123 or a vibration device may be provided to further enhance the adhesion by applying ultrasonic or vibration energy when the window contacts the panel.

[0091] refer to Fig.13 and Fig.14 A linear volume adjustment component 124 may also be provided so that the pressure pad 121 can be rapidly deployed.

[0092] refer to Fig.15 , the support portion 127 may be composed of a first support portion 127a and a second support portion 127b that can be spaced apart in the length direction. The first support portion 127a and the second support portion 127b are connected to the drive shafts 128a and 128b and can be spaced apart from each other in the axial direction. Therefore, even in the case where the length of the window 11 is long, the first support portion 127a and the second support portion 127b can be spaced apart to perform the lamination operation without replacing an additional pressurizing module 120.

[0093] refer to Fig.16 , the first fixing module 131a and the second fixing module 131b can be spaced apart in the first direction, and the first supporting portion 127a and the second supporting portion 127b can be spaced apart in the second direction (Y-axis direction) perpendicular to the first direction (X-axis direction). Therefore, even if the width of the window 11 is widened or the length of the window 11 is increased, the operation can be performed immediately without replacing the fixing module 130 or the pressurizing module.

[0094] At this time, since the pressure pad 121 has elastic force, the first support portion 127a and the second support portion 127b can be spaced apart by a predetermined distance even when the pressure pad 121 is fixed. If the distance between the first support portion 127a and the second support portion 127b is greater than the elongation force of the pressure pad 121, a larger pressure pad 121 can be replaced.

[0095] refer to Fig.17 , the pressure pad 121 may include a first pressure pad 121a disposed on the first support portion 127a, and a second pressure pad 121b disposed on the second support portion 127b. Therefore, the first pressure pad 121a and the second pressure pad 121b can be freely spaced apart according to the window spacing for lamination operation without replacing the pressure pad.

[0096] Although the preferred embodiments of the present invention have been described above, it will be appreciated by those skilled in the art that various modifications and changes may be made to the present invention without departing from the spirit and scope of the present invention as set forth in the claims.
