[0037] Referring to Figures 1 to 3 , Figure 1 shows a perspective view of the fitting device provided by an embodiment of the present application, Figure 2 is Figure 1 a side view of the first fitting assembly and the second fitting assembly in the fitting device shown, Figure 3 is Figure 2 a side view of the fitting device shown when the pushing bag is in an inflated state, the fitting device 10 provided by an embodiment of the present application is used to fit the flexible element 30 and the curved surface element 20, wherein in the fitting process, one area of the flexible element 30 can first contact the curved surface element 20, and then other areas adjacent to the first contact area also gradually contact the curved surface element 20 to complete the fitting. In the above fitting process, the fitting area gradually spreads outward from the first contact area, so that the gas between the flexible element 30 and the curved surface element 20 can also be gradually squeezed out, reducing the probability of gas residing between the flexible element 30 and the curved surface element 20 to form bubbles, and improving the yield of the fitting.
[0038] Referring to Figure 2 and Figure 3In one embodiment, the attaching device 10 comprises a first attaching assembly 100 for picking up the curved element 20 and a second attaching assembly 200 for picking up the flexible element 30, and at least one of the second attaching assembly 200 and the first attaching assembly 100 is capable of moving towards the other so as to attach the flexible element 30 to the curved element 20. The second attaching assembly 200 comprises a second picking structure 210 for picking up the flexible element 30 and a pushing bag 220 which is flexible. The pushing bag 220 comprises a bulging portion 221 which has a greater bulging amplitude along the attaching direction S than other regions, and the bulging portion 221 first abuts against the side of the flexible element 30 picked up by the second picking structure 210 which is away from the first attaching assembly 100, so that the corresponding partial region of the flexible element 30 is first attached to the curved element 20. Furthermore, in the direction away from the bulging portion 221, the bulging amplitude of each region of the pushing bag 220 along the attaching direction S gradually decreases.
[0039] In the attaching device 10 described above, the first attaching assembly 100 picks up the curved element 20 and the second picking structure 210 picks up the flexible element 30, and at least one of them is capable of moving towards the other so as to attach the curved element 20 to the flexible element 30. Furthermore, the second attaching assembly 200 further comprises the pushing bag 220, and the bulging portion 221 of the pushing bag 220 has a greater bulging amplitude along the attaching direction S than other regions, so that the bulging portion 221 can first contact and abut against the flexible element 30 during the attaching process, so that the corresponding partial region of the flexible element 30 is first attached to the curved element 20. With further attaching, the region of the curved element 20 which contacts the flexible element 30 provides a reaction force support to the flexible element 30, and the bulging amplitude of the portion of the pushing bag 220 which has contacted the flexible element 30 is limited by abutting against the flexible element 30, while the portion of the pushing bag 220 which has not contacted the flexible element 30 is not affected, so that the contact area of the pushing bag 220 which contacts the flexible element 30 gradually increases. Furthermore, in the direction away from the bulging portion 221, the bulging amplitude of each region of the pushing bag 220 along the attaching direction S gradually decreases, so that starting from the region where the bulging portion 221 is located, each region of the pushing bag 220 gradually contacts and attaches to the flexible element 30 from the bulging portion 221 to the region away from the bulging portion 221, and gradually pushes the corresponding region of the flexible element 30 to contact the curved element 20. In this way, the pushing bag 220 can gradually squeeze and discharge the gas between the flexible element 30 and the curved element 20 during the attaching process, so as to reduce the air bubbles after the attaching process and improve the product yield.
[0040] It should be noted that in the conventional technology, a profiling auxiliary tool is usually used to push the flexible element 30 so as to make the flexible element 30 have a curvature corresponding to the curved element 20, so that the curved element 20 and the flexible element 30 can be attached in a substantially parallel posture. However, please refer toFigure 4 When the curvature of the curved element 20 is large, the flexible element 30 is bent to a larger extent under the action of the profiled auxiliary workpiece, and thus some regions of the flexible element 30 are likely to be in contact with the curved element 20 unexpectedly, so that the gas cannot flow out of the regions, resulting in many bubbles after lamination. Unlike the prior art, the lamination device 10 provided by the present application can diffuse the contact position of the flexible element 30 with the curved element 20 from a local region (i.e., the region opposite the bulging portion 221) to the whole, and the regions of the flexible element 30 are sequentially in contact with the curved element 20, and the lamination process has the action of discharging gas, so as to effectively reduce the gas between the flexible element 30 and the curved element 20, and reduce the bubbles after lamination.
[0041] Please refer to Figure 4 As one of the examples, the curved element 20 can be a curved glass cover plate (CG, Cover Glass). Please refer to Figure 5 As one of the examples, the flexible element 30 can be a flexible display screen, at this time the flexible element 30 includes a flexible screen body 31 and a supporting film 32, the flexible screen body 31 is laminated with the supporting film 32, the supporting film 32 can provide support for the flexible screen body 31, and the second lamination assembly 200 can pick up the flexible element 30 by clamping the supporting film 32. Further, the flexible element 30 can be coated with OCA (Optically Clear Adhesive) glue to improve the adhesion performance of the flexible element 30 and the curved element 20 and the optical performance after lamination. Of course, the curved element 20 and the flexible element 30 can also be other elements, for example, the flexible element 30 can be a flexible film, and the curved element 20 is a film element to be laminated with a curved surface. The same is true for other cases, and thus will not be described again. In the case of no contradiction, the bulging amplitude referred to by each embodiment of the present application refers to the bulging amplitude in the lamination direction S, which will not be described again in each embodiment.
[0042] In one of the embodiments, the push capsule 220 can be configured as a solid flexible body, and the bulging portion 221 always has the maximum bulging amplitude. At this time, the second lamination assembly 200 can further include a pushing driver (not shown, the same below), the pushing driver is connected with the push capsule 220 to drive the push capsule 220 to move along the lamination direction S, so that the push capsule 220 is lifted to a position where each region is in contact with the flexible element 30.
[0043] Please refer to Figure 2 and Figure 3In one embodiment, the push bladder 220 can be configured as a hollow bladder capable of flexible expansion under filling. The fitting device 10 further comprises an expansion generator (not shown in the figure, the same below) in communication with the push bladder 220 to provide a filling medium to the push bladder 220 to expand the push bladder 220. When the push bladder 220 is in the expanded state, the expansion amplitude of the bulge portion 221 is greater than other regions, and in the direction away from the bulge portion 221, the bulge amplitude of the regions of the push bladder 220 in the fitting direction S gradually decreases. When the push bladder 220 is in the unexpanded state, the bulge portion 221 is concave relative to other regions in the fitting direction S. In this embodiment, when the bulge portion 221 contacts the flexible element 30 during fitting, further providing the filling medium to the push bladder 220 can gradually expand the other regions of the push bladder 220 to the amplitude of contacting the flexible element 30 to gradually squeeze out the gas between the flexible element 30 and the curved surface element 20.
[0044] In one embodiment, when the push bladder 220 is in the unexpanded state, the bulge portion 221 can also be in the same plane as the other regions, at which time the push bladder 220 has elasticity. The push bladder 220 is elastically bulged after being filled with the filling medium, and abuts against the flexible element 30. The regions of the push bladder 220 can have different stiffness coefficients or structural dimensions (such as thickness), so that after the push bladder 220 is filled with the filling medium, the regions have different bulge amplitudes.
[0045] In one embodiment, the expansion generator is used to provide gas or liquid to the push bladder 220 to expand the push bladder 220. The fitting device 10 further comprises a pressure valve in communication between the expansion generator and the push bladder 220, and the pressure valve is used to control the pressure in the push bladder 220 within a set range, to reduce the risk of the push bladder 220 expanding too much and damaging the flexible element 30. Taking the filling medium as gas for example, the pressure valve can adjust the amount of air provided by the expansion generator to the push bladder 220, to achieve controllable expansion and deformation of the push bladder 220, to achieve the above-mentioned gradual gas discharge effect. For example, in one embodiment, the expansion generator can be configured as an air flow generator, at which time the above-mentioned filling medium is gas. For another example, in another embodiment, the expansion generator can be configured as a hydraulic pump, at which time the above-mentioned filling medium is liquid. Of course, the expansion generator can also be configured as other components capable of expanding the push bladder 220, which will not be described here.
[0046] Please refer again to Figure 1In one embodiment, the laminating apparatus 10 further comprises a base 700, and the first laminating assembly 100 and the second laminating assembly 200 are arranged on the base 700. The laminating apparatus 10 further comprises a pump assembly 300, which comprises the above-mentioned inflation generator and the below-mentioned suction component and negative pressure generator, and the pump assembly 300 is arranged beside the base 700 to provide positive pressure or negative pressure to the required position through a pipeline or other communication component.
[0047] Referring to Figure 3 In one embodiment, the bulge 221 is arranged at the opposite central region of the push bag 220 in the plane of the vertical laminating direction S, so that the push bag 220 can gradually discharge the gas between the flexible element 30 and the curved element 20 from the central region to the periphery, thereby reducing the air bubbles after lamination. Of course, when the curved element 20 has other special convex shapes, the distribution position of the bulge 221 can also be adaptively adjusted according to the shape of the curved element 20.
[0048] Referring to Figure 6 and Figure 7 In one embodiment, the first laminating assembly 100 comprises a first cover 110 and a first pickup structure 120, and the first pickup structure 120 is arranged in the first cover 110 and is used to pick up the curved element 20. The second laminating assembly 200 further comprises a second cover 2310, and the second pickup structure 210 is arranged in the second cover 2310. The first cover 110 and the second cover 2310 are both hollow. At least one of the first cover 110 and the second cover 2310 can be buckled with the other to form a closed laminating cavity. The laminating apparatus 10 further comprises a negative pressure generator, which is in communication with the inner cavities of the first cover 110 and / or the second cover 2310 to form a negative pressure in the laminating cavity after the first cover 110 and the second cover 2310 are buckled, thereby sucking and discharging the gas in the laminating cavity. It is easy to understand that the first pickup structure 120 and the second pickup structure 210 are both located in the laminating cavity, so that the curved element 20 and the flexible element 30 are laminated in the laminating cavity. Therefore, the negative pressure generator is used to form a negative pressure in the laminating cavity, thereby further improving the smoothness of discharging the gas between the flexible element 30 and the curved element 20 and reducing the air bubbles after lamination.
[0049] Referring to Figure 6 and Figure 7 In one embodiment, the first cover 110 and the second cover 2310 are both provided with an opening near one side, and the two openings are aligned with each other, so that the inner cavities of the first cover 110 and the second cover 2310 are in communication with each other to form the laminating cavity after the first cover 110 and the second cover 2310 are buckled.
[0050] Referring to Figure 7In one embodiment, the first bonding assembly 100 comprises a gantry 140, which is arranged on the base 700, and the first cover 110 is movably arranged on the gantry 140, so that the first cover 110 and the first pickup structure 120 arranged in the first cover 110 have a higher position relative to the second bonding assembly 200, facilitating the longitudinal bonding of the two.
[0051] Referring to Figure 7 and Figure 8 In one embodiment, the first bonding assembly 100 comprises a first longitudinal driving structure 150, which is arranged on the gantry 140 and connected with the first cover 110 to drive the first cover 110 to be buckled with the second cover 2310 along the bonding direction S.
[0052] In one embodiment, the first longitudinal driving structure 150 can be configured to drive the first cover 110 to move along the bonding direction S through a transmission structure of a motor, a screw rod and a nut. Of course, the first longitudinal driving structure 150 can also drive the first cover 110 to move in other ways, such as a pneumatic cylinder or a hydraulic cylinder.
[0053] Referring to Figures 7 to 9 In one embodiment, the first pickup structure 120 comprises a support seat 1210, a suction component (not shown, the same below) and a clamping component 1220. The suction component is in communication with a hole in the support seat 1210 and is used to suction the curved surface element 20 to the support seat 1210. The suction fixation can directly and effectively pick up and fix the curved surface element 20 and reduce the damage to the curved surface element 20. The clamping component 1220 is used to clamp the curved surface element 20 suctioned to the support seat 1210. Since the curved surface element 20 and the flexible element 30 are bonded in the bonding cavity with negative pressure, the clamping component 1220 is configured to clamp the curved surface element 20 on the support seat 1210, which can improve the position stability of the curved surface element 20 and reduce the risk of the curved surface element 20 falling off due to the suction component providing a negative pressure suction weaker than the negative pressure in the bonding cavity.
[0054] Referring to Figure 9 , in combination with Figure 2 In one embodiment, the support seat 1210 comprises a contact surface 1211, which is configured as a curved surface for bonding the curved surface element 20. Along the bonding direction S, the region of the contact surface 1211 closest to the second bonding assembly 200 (i.e. the most protruding part in the bonding direction S) is aligned with the bulging part 221, i.e. when the first pickup structure 120 picks up the curved surface element 20, the bulging part 221 is aligned with the most protruding part of the curved surface element 20 in the bonding direction S, so that the pushing bag 220 can gradually extrude the gas between the flexible element 30 and the curved surface element 20 from the most protruding part, improving the smoothness of the exhaust.

It can be understood that guide rails can also be arranged on other components that can slide and move, so as to improve the stability of the movement, which will not be described one by one in each embodiment.
[0066] In one embodiment, the tensioning driving structure 2130 and the second longitudinal driving structure 2140 can be configured to be driven by a motor in combination with a transmission structure, such as a screw-nut transmission structure and a gear-rack transmission structure.

Since the support surface 511 is between the first lamination assembly 100 and the second lamination assembly 200 along the lamination direction S, the movement of the supporting structure 520 on the support surface 511 can conveniently load the curved surface element 20 to the first lamination assembly 100. It can be understood that the supporting structure 520 can also be moved to a position out of alignment with the first lamination assembly 100 to facilitate the loading of the curved surface element 20 to the supporting structure 520.

[0075] Please continue to refer to Figure 13 In one embodiment, the laminating device 10 further comprises a detector 600, the detector 600 being arranged on the supporting structure 520, so that the detector 600 can move with the supporting structure 520 to the position between the first laminating assembly 100 and the second laminating assembly 200.

[0076] Further, the number of the detector 600 can be at least two, one of which takes a picture of the curved element 20 picked up by the first laminating assembly 100, and the other of which takes a picture of the flexible element 30 picked up by the second laminating assembly 200.

[0077] Please refer to Figure 1 In one embodiment, the first laminating assembly 100, the second laminating assembly 200, the transverse movement structure 400 and the feeding assembly 500 are collectively referred to as a laminating module, and the laminating assembly can comprise a plurality of laminating modules to improve the laminating efficiency.
[0078] For the purpose of facilitating understanding of the laminating device 10 provided in the present application, the steps of laminating the curved element 20 and the flexible element 30 by using the laminating device 10 are briefly described as follows:
[0079] The curved surface element 20 is filled into the supporting structure 520, the supporting structure 520 is moved to a position in alignment with the first laminating assembly 100, at this time the adsorption part is adsorbed and fixed to the curved surface element 20 in cooperation with the supporting seat 1210, and the clamping part 1220 clamps the curved surface part.
[0080] The flexible element 30 is fed to the second laminating assembly 200. Wherein, after the claw part 2112 clamps the flexible element 30, the two claw parts 2112 move away from each other to tension the flexible element 30, so that the flexible element 30 is in a balanced state of tension.
[0081] The supporting structure 520 is moved between the first laminating assembly 100 and the second laminating assembly 200, so that the detector 600 takes a photo of the curved surface element 20 picked up by the first laminating assembly 100 and the flexible element 30 picked up by the second laminating assembly 200, and corrects the relative positions of the two.
[0082] The first cover body 110 and the second cover body 2310 are buckled to form a closed laminating cavity, and the negative pressure generator evacuates the laminating cavity. When the vacuum value in the laminating cavity reaches the expected requirement, the expansion generator provides the filling medium to the push capsule 220. The push capsule 220 expands and bulges, so that the flexible element 30 gradually spreads from the partial area contacting the curved surface element 20 to the whole laminating curved surface element 20, while laminating and discharging the gas between the flexible element 30 and the curved surface element 20.
[0083] It should be noted that each embodiment of the present application and the drawings attached to the specification are taken as an example for laminating the curved surface element 20 with a lower convex curved surface. It should be understood that the laminating device 10 described in each embodiment of the present application is also compatible with laminating the flexible element 30 with the curved surface element 20 having a lower concave curved surface, and the lower concave curved surface in the curved surface element 20 is used for laminating with the flexible element 30 (i.e. Figure 4 The top surface of the curved surface element 20 is used for laminating). At this time, the shape of the contact surface 1211 of the supporting seat 1210 can be adjusted accordingly to adapt to picking up the curved surface element 20.
[0084] Each technical feature of the above-described embodiments can be combined arbitrarily. In order to make the description simple, not all possible combinations of each technical feature in the above-described embodiments are described, however, as long as the combination of these technical features does not exist contradictory, it should be considered as the scope of the present application.
[0085] The above embodiments only express several implementation ways of the present application, and the description is relatively specific and detailed, but it should not be understood as a limitation to the patent scope of the application. It should be pointed out that for ordinary skilled persons in the art, several modifications and improvements can be made without departing from the concept of the present application, which all belong to the protection scope of the present application. Therefore, the protection scope of the patent of the present application should be subject to the appended claims.
