[0001] The present application relates to the technical field of bonding processes, and in particular to a bonding device. Background Art

[0002] With the rapid development of electronic display technology, flexible display technology has emerged. With its thin, bendable and foldable features, flexible display has brought new possibilities to the design of electronic devices and is widely used in smart phones, tablet computers, smart wearable devices and other fields.

[0003] In practical applications of flexible displays, it is usually necessary to bond them to curved glass cover plates to provide protection, enhance optical performance and achieve a better appearance. Traditional bonding methods mainly rely on manual bonding or simple mechanical auxiliary equipment to bond.

[0009] In one of the embodiments, in a plane perpendicular to the fitting direction, the bulge is located in a relatively central area of ​​the push bladder.

[0010] In one embodiment, the second picking structure includes a clamping claw component, and the number of the clamping claw components is at least two, which are respectively used to clamp the opposite ends of the flexible element; at least one of the clamping claw components includes a connecting seat, a claw portion and an elastic connecting member, the claw portion is movably arranged on the connecting seat, and the elastic connecting member is connected between the connecting seat and the claw portion. When the pushing bag abuts against the flexible element, the claw portion moves toward the direction of the clamping claw component located at the other end of the flexible element, and causes the elastic connecting member to elastically deform.

[0011] In one embodiment, the second bonding component also includes a support, and the second picking structure also includes a bracket, a tensioning drive structure and a second longitudinal drive structure. The bracket is movably provided on the support along the bonding direction, and the clamping jaw component is movably provided on the support along a direction perpendicular to the bonding direction. The tensioning drive structure is connected to the clamping jaw component to drive at least two clamping jaw components arranged opposite to each other to move toward and away from each other. The pushing bag is provided on the support, and the pushing bag is located on the side of the clamping jaw component away from the first bonding component along the bonding direction. The second longitudinal drive structure is provided on the support and connected to the bracket to drive the bracket to move relative to the support along the bonding direction.

[0012] In one embodiment, the expansion generator is used to provide gas or liquid to the push bladder to expand the push bladder, and the fitting device also includes a pressure valve, which is connected between the expansion generator and the push bladder, and the pressure valve is used to control the pressure in the push bladder within a set range.

[0013] In one embodiment, the bonding device also includes a negative pressure generator, the first bonding component includes a first cover body and a first picking structure disposed in the first cover body, the second bonding component also includes a second cover body, the second picking structure is disposed in the second cover body, at least one of the first cover body and the second cover body can be buckled with the other along the bonding direction to form a closed bonding cavity, the negative pressure generator is connected to the inner cavity of the first cover body and / or the second cover body to form a negative pressure in the bonding cavity after the first cover body and the second cover body are buckled; the first picking structure includes a support seat, an adsorption component and a clamping component, the adsorption component is connected to the channel in the support seat, and is used to adsorb the curved surface element to the support seat, and the clamping component is used to clamp the curved surface element adsorbed on the support seat.

[0014] In one embodiment, the bonding device further includes a loading component, the loading component includes a stand and a supporting structure, the supporting structure is used to carry the curved element, the stand includes a supporting surface located between the first bonding component and the second bonding component in the bonding direction, the supporting structure is movably provided on the supporting surface to move to a position aligned with the first bonding component so that the first bonding component can remove the curved element it carries.

[0016] In the above-mentioned laminating device, the first laminating component picks up the curved element, and the second picking structure picks up the flexible element.

In addition, the second laminating component also includes a push capsule, and the bulging portion of the push capsule has a larger bulging amplitude in the laminating direction than other areas. Therefore, during laminating, the bulging portion can first contact and abut the flexible element, so that the corresponding partial area of ​​the flexible element (i.e., the area abutted by the bulging portion) first contacts and abuts the curved element. With further laminating, the area of ​​the curved element that contacts the flexible element provides reaction force support to the flexible element, and the bulging amplitude of the part of the push capsule that has contacted the flexible element is limited by supporting the flexible element, while the part of the push capsule that has not contacted the flexible element is not affected, so the contact area of ​​the push capsule that contacts the flexible element gradually increases. Moreover, in the direction away from the bulge, the bulge amplitude of each area of ​​the push bag along the bonding direction gradually decreases, so starting from the area where the bulge is located, other areas on the push bag gradually contact and fit with the flexible element from near to far from the bulge, and gradually push the corresponding area of ​​the flexible element to contact the curved surface element. Therefore, during bonding, the push bag can gradually squeeze out the gas between the flexible element and the curved surface element, reduce bubbles after bonding, and improve the product qualification rate.

[0037] See also Figures 1 to 3 , Figure 1 FIG. 1 shows an axonometric diagram of a bonding device provided in an embodiment of the present application. Figure 2 for Figure 1 A side view of a first bonding component and a second bonding component in the bonding device shown, Figure 3 for Figure 2 The side view of the push bladder in the bonding device shown is in an expanded state. The bonding device 10 provided in one embodiment of the present application is used to bond the flexible element 30 to the curved element 20, wherein during the bonding process, one area of ​​the flexible element 30 can first contact the curved element 20, and then other areas adjacent to the first contacted area also gradually contact the curved element 20 to complete the bonding. During the above bonding process, the bonding area gradually diffuses outward from the first contacted area, so the gas between the flexible element 30 and the curved element 20 can also be gradually squeezed out, reducing the probability of gas staying between the flexible element 30 and the curved element 20 to form bubbles, and improving the bonding yield rate.

[0038] See also Figure 2 and Figure 3In one embodiment, the laminating device 10 includes a first laminating component 100 and a second laminating component 200. The first laminating component 100 is used to pick up the curved component 20, and the second laminating component 200 is used to pick up the flexible component 30. Part of the structure of at least one of the second laminating component 200 and the first laminating component 100 can move toward the other, so that the flexible component 30 is laminated with the curved component 20. The second laminating component 200 includes a second picking structure 210 and a push capsule 220. The second picking structure 210 is used to pick up the flexible component 30, and the push capsule 220 is a flexible member. Among them, the push capsule 220 includes a bulging portion 221. The bulging amplitude of the bulging portion 221 along the laminating direction S is greater than that of other areas, and the bulging portion 221 first abuts against the side of the flexible component 30 picked up by the second picking structure 210 that is away from the first laminating component 100, so that the corresponding part of the flexible component 30 is first laminated with the curved component 20. Furthermore, in the direction away from the bulging portion 221 , the bulging amplitude of each region of the push bladder 220 along the fitting direction S gradually decreases.

[0039] In the above-mentioned laminating device 10, the first laminating component 100 picks up the curved element 20, and the second picking structure 210 picks up the flexible element 30, and a part of the structure of at least one of the two can be close to the other, so that the curved element 20 and the flexible element 30 are laminated. In addition, the second laminating component 200 also includes a push capsule 220, and the bulging portion 221 of the push capsule 220 has a larger bulging amplitude in the laminating direction S than other areas, so that during laminating, the bulging portion 221 can first contact and abut the flexible element 30, so that the corresponding part of the flexible element 30 (i.e., the area abutted by the bulging portion 221) first contacts and abuts the curved element 20. With further bonding, the area of ​​the curved element 20 in contact with the flexible element 30 provides reaction force support to the flexible element 30, and the bulging amplitude of the part of the push capsule 220 that has been in contact with the flexible element 30 is limited by supporting the flexible element 30, while the part of the push capsule 220 that is not in contact with the flexible element 30 is not affected, so the contact area of ​​the push capsule 220 in contact with the flexible element 30 gradually increases. In addition, in the direction away from the bulging portion 221, the bulging amplitude of each area of ​​the push capsule 220 along the bonding direction S gradually decreases, so starting from the area where the bulging portion 221 is located, the other areas on the push capsule 220 gradually contact and bond with the flexible element 30 from the bulging portion 221 from near to far, and gradually push the corresponding area of ​​the flexible element 30 to contact the curved element 20. Therefore, during bonding, the push capsule 220 can gradually squeeze out the gas between the flexible element 30 and the curved element 20, reduce bubbles after bonding, and improve the product qualification rate.

[0040] It should be noted that in conventional technology, a profiling auxiliary tool is usually used to push the flexible element 30 so that the flexible element 30 has a curvature corresponding to the curved element 20, so that the curved element 20 and the flexible element 30 can fit in a substantially parallel posture. Figure 4 When the curvature of the curved element 20 is large, the bending degree of the flexible element 30 is also greater under the action of the profiling auxiliary workpiece. Therefore, it is easy for some areas of the flexible element 30 to accidentally contact the curved element 20 first, so that the gas cannot flow out from this area, resulting in many bubbles after bonding. Different from this, the bonding device 10 provided in the present application can make the contact part between the flexible element 30 and the curved element 20 diffuse from the local area (i.e., the area aligned with the bulge 221) to the whole, and each area of ​​the flexible element 30 is contacted and bonded with the curved element 20 in sequence. There is a gas discharge action during the bonding process, so it can effectively reduce the gas between the flexible element 30 and the curved element 20 and reduce bubbles after bonding.

[0041] See also Figure 4 As one example, the curved surface element 20 may be a curved surface glass cover plate (CG, CoverGlass). Figure 5 As one example, the flexible element 30 may be a flexible display screen, in which case the flexible element 30 includes a flexible screen body 31 and a carrier film 32, the flexible screen body 31 is bonded to the carrier film 32, the carrier film 32 can provide support for the flexible screen body 31, and the second bonding component 200 may pick up the flexible element 30 by clamping the carrier film 32. Furthermore, the flexible element 30 may also be coated with OCA (Optically Clear Adhesive) glue to improve the bonding performance between the flexible element 30 and the curved element 20 and the optical performance after the two are bonded. Of course, the curved element 20 and the flexible element 30 may also be other elements, for example, the flexible element 30 may be a flexible film, and the curved element 20 is an element with a curved surface to be bonded. The same is true for other situations, so they will not be repeated. Unless there is a contradiction, the bulging amplitude referred to in each embodiment of the present application refers to the bulging amplitude in the bonding direction S, and each embodiment will not be repeated one by one.

[0042] In one embodiment, the push capsule 220 can be constructed as a solid flexible body, and the bulging portion 221 always has the largest bulging amplitude. In this case, the second fitting component 200 can be configured to further include a push driver (not shown in the figure, the same below), which is connected to the push capsule 220 to drive the push capsule 220 to move along the fitting direction S, so that the push capsule 220 is pushed up to a position where each area is in contact with the flexible element 30.

[0043] See also Figure 2 and Figure 3In one embodiment, the push bladder 220 can be constructed as a hollow bladder, and the push bladder 220 can be flexibly expanded by filling. The laminating device 10 also includes an expansion generator (not shown in the figure, the same below), which is connected to 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 an expanded state, the expansion and swelling amplitude of the bulge 221 is greater than that of other areas, and in the direction away from the bulge 221, the swelling amplitude of each area of ​​the push bladder 220 along the laminating direction S gradually decreases. When the push bladder 220 is in an unexpanded state, the bulge 221 is concave relative to other areas in the laminating direction S. In this embodiment, during laminating, after the bulge 221 contacts the flexible element 30, further providing the filling medium to the push bladder 220 can make the other areas of the push bladder 220 gradually expand to the amplitude of contacting the flexible element 30, so as to gradually squeeze out the gas between the flexible element 30 and the curved element 20.

[0044] In one embodiment, when the push bladder 220 is in an unexpanded state, the bulge 221 can also be in the same plane as other areas, and the push bladder 220 is elastic. After being filled with the filling medium, the push bladder 220 bulges elastically and abuts against the flexible element 30. Each part of the push bladder 220 can have a different stiffness coefficient or structural size (such as thickness), so that after the push bladder 220 is filled with the filling medium, each part of the area presents a different bulge amplitude.

[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 also includes a pressure valve, which is connected between the expansion generator and the push bladder 220. 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 as an example, the pressure valve can adjust the amount of gas charged to the push bladder 220 by the expansion generator to achieve controllable expansion and deformation of the push bladder 220, so as to achieve the above-mentioned effect of gradually discharging gas. For example, in one of the embodiments, the expansion generator can be configured as an airflow generator, in which case the above-mentioned filling medium is gas. For example, in another embodiment, the expansion generator can be configured as a hydraulic pump, in which case the above-mentioned filling medium is liquid. Of course, the expansion generator can be configured as other components that can expand the push bladder 220, which will not be repeated here.

[0046] Please refer again Figure 1In one embodiment, the laminating device 10 further includes a base 700, and the first laminating component 100 and the second laminating component 200 are both disposed on the base 700. The laminating device 10 further includes a pump component 300, and the pump component 300 includes the above-mentioned expansion generator and the adsorption component and negative pressure generator mentioned below. The pump component 300 is disposed beside the base 700, and provides positive pressure or negative pressure to the required part through a connecting member such as a pipeline.

[0047] See also Figure 3 In one embodiment, in a plane perpendicular to the bonding direction S, the bulge 221 is located in a relatively central area of ​​the push capsule 220, so that the push capsule 220 can gradually discharge the gas between the flexible element 30 and the curved element 20 from the central area to the periphery, thereby reducing bubbles after bonding. 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] See also Figure 6 and Figure 7 In one embodiment, the first laminating component 100 includes a first cover 110 and a first picking structure 120, wherein the first picking structure 120 is disposed in the first cover 110, and the first picking structure 120 is used to pick up the curved surface element 20. The second laminating component 200 also includes a second cover 2310, wherein the second picking structure 210 is disposed in the second cover 2310. Both the first cover 110 and the second cover 2310 are hollow. At least one of the first cover 110 and the second cover 2310 can be buckled with the other along the laminating direction S to form a closed laminating cavity. The laminating device 10 also includes a negative pressure generator, which is connected to the inner cavity 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, and the gas in the laminating cavity is sucked out. It is easy to understand that the first pick-up structure 120 and the second pick-up structure 210 are both located in the bonding chamber, so the curved element 20 and the flexible element 30 are bonded in the bonding chamber. Thus, the negative pressure generator forms a negative pressure in the bonding chamber, further improving the smoothness of the gas discharge between the flexible element 30 and the curved element 20, and reducing bubbles after bonding.

[0049] See also Figure 6 and Figure 7 In one embodiment, the first cover body 110 and the second cover body 2310 are both provided with openings on one side, and the two openings are aligned with each other so that after the first cover body 110 and the second cover body 2310 are buckled together, the inner cavities of the two are connected to each other to form a fitting cavity.

[0050] See also Figure 7In one embodiment, the first bonding component 100 includes a gantry 140, which is mounted on the base 700, and the first cover 110 is movably disposed on the gantry 140, so that the first cover 110 and the first picking structure 120 disposed in the first cover 110 have a higher position relative to the second bonding component 200, so as to facilitate the longitudinal bonding of the two.

[0051] See also Figure 7 and Figure 8 In one embodiment, the first fitting component 100 includes a first longitudinal driving structure 150, which is disposed on the gantry 140 and connected to the first cover body 110 to drive the first cover body 110 to engage with the second cover body 2310 along the fitting direction S.

[0052] In one embodiment, the first longitudinal driving structure 150 may be configured to drive the first cover 110 to move along the fitting direction S through a transmission structure of a motor, a lead screw and a nut. Of course, the first longitudinal driving structure 150 may also drive the first cover 110 to move in other ways, such as a cylinder or a hydraulic cylinder.

[0053] See also Figures 7 to 9 In one embodiment, the first pickup structure 120 includes a support seat 1210, an adsorption component (not shown in the figure, the same below) and a clamping component 1220. The adsorption component is connected to the channel in the support seat 1210 and is used to adsorb the curved surface element 20 to the support seat 1210. The use of adsorption fixation can directly and effectively pick up and fix the curved surface element 20, and reduce possible damage to the curved surface element 20. The clamping component 1220 is used to clamp the curved surface element 20 adsorbed on the support seat 1210. Since the curved surface element 20 and the flexible element 30 are bonded in a bonding chamber 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 negative pressure adsorption effect provided by the adsorption component being weaker than the negative pressure effect in the bonding chamber.

[0054] See also Fig. 9 , combined with Figure 2 In one embodiment, the support seat 1210 includes a contact surface 1211, which is configured as a curved surface for fitting the curved surface element 20.

[0078] To facilitate understanding of the bonding device 10 provided in the present application, the following is a brief description of the steps of bonding the curved element 20 and the flexible element 30 using the bonding device 10:

[0079] The curved surface element 20 is loaded into the supporting structure 520 , and the supporting structure 520 moves to a position aligned with the first bonding component 100 . At this time, the adsorption component cooperates with the support seat 1210 to adsorb and fix the curved surface element 20 , and the clamping component 1220 clamps the curved surface component.

[0080] The flexible element 30 is loaded onto the second laminating assembly 200. After the claws 2112 clamp the flexible element 30, the two claws 2112 move away from each other to tension the flexible element 30, so that the flexible element 30 is in a horizontal state with balanced tension.

[0081] The supporting structure 520 moves between the first bonding component 100 and the second bonding component 200, so that the detector 600 takes pictures of the curved component 20 picked up by the first bonding component 100 and the flexible component 30 picked up by the second bonding component 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 fitting cavity, and the negative pressure generator evacuates the fitting cavity. When the vacuum value in the fitting cavity reaches the expected requirement, the expansion generator provides the filling medium to the push bladder 220. The push bladder 220 expands and swells, so that the flexible element 30 gradually diffuses from a partial area contacting the curved surface element 20 to the entire fitting curved surface element 20, and discharges the gas between the flexible element 30 and the curved surface element 20 during the fitting.

[0083] It should be noted that the embodiments of the present application and the drawings in the specification are described by taking the curved surface element 20 having a downward convex curved surface, and the downward convex curved surface is used for bonding as an example. It should be understood that the bonding device 10 described in the embodiments of the present application can also be compatible with bonding the flexible element 30 with the curved surface element 20 having a downward concave curved surface, and the downward concave curved surface of the curved surface element 20 is used to bond with the flexible element 30 (i.e. Figure 4 The top surface of the curved component 20 is used for fitting. At this time, the shape of the contact surface 1211 of the support seat 1210 can be adjusted accordingly to adapt to picking up the curved component 20.

[0084] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0085] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application.
