It should be noted that, in the case of no conflict, different features in the embodiments of the present application may be combined with each other.
Referring to fig. 1, fig. 1 is a schematic diagram of a bonding tool 10 according to the present embodiment, the bonding tool 10 may be used for bonding a display module to a curved cover, the bonding tool 10 includes a pushing portion 100, a receiving bag set 200, and a circulation interface 300, and the receiving bag set 200 includes a plurality of mutually separable receiving bags.
The pushing part 100 is a pushing surface on a surface near the display module, and the accommodating bag set 200 is located on the pushing surface. Each of the pockets in the set 200 is configured to hold a flowable material. Illustratively, the flowable material may be a liquid or a gas.
Optionally, in this embodiment, the accommodating pocket is an elastic accommodating pocket, and the stiffness of the pushing surface is greater than the stiffness of the accommodating pocket. For example, the pushing portion 100 may be made of a silicone material having relatively high rigidity but still having a certain elasticity; the accommodating bag is made of a material with relatively small elasticity and easy deformation.
The flowable material flows into or out of the set of containment pockets 200 through the flow-through interface 300 to place the set of containment pockets 200 in different deformation states. When the accommodating bag set 200 is in different deformation states, the accommodating bag set 200 may have different profiles, so as to apply forces in different directions to the display modules disposed on the accommodating bag set 200.
In some possible implementations, the set 200 can be provided with at least three different deformation states by controlling the amount of flowable material in the set 200.
Referring to fig. 1 again, when the flowable material flows out of the accommodating bag set 200 to make the accommodating bag set 200 in the first deformed state, adjacent accommodating bags in the accommodating bag set 200 are attached to each other. For example, by extracting the flowable material from the set of pockets 200, the amount of flowable material in each pocket may be reduced, allowing each pocket to be more tightly adsorbed on the pushing surface, thereby allowing adjacent pockets in the set of pockets 200 to be adhered to one another. In the first deformed state, the outer shape profile of the plurality of the accommodating pockets in the accommodating pocket set 200 may be similar to the outer shape profile of the pressing surface.
Referring to fig. 2, when the flowable material is filled into the accommodating bladder set 200 to make the accommodating bladder set 200 in the second deformed state, at least part of the adjacent accommodating bladders in the accommodating bladder set 200 are separated from each other. Alternatively, in the present embodiment, a side of the set of accommodating cells 200 adjacent to the pressing surface is connected to the pressing surface, and the accommodating cells in the set of accommodating cells 200 are separated from each other in a direction parallel to the pressing surface. Therefore, when the set of the accommodation bags 200 is filled with an appropriate amount of the flowable material, the respective accommodation bags are no longer closely adsorbed on the pressing surface, so that at least part of the adjacent accommodation bags are separated from each other in a direction parallel to the pressing surface by the self-gravity.
Referring to fig. 3, when the flowable material is filled into the accommodating bladder set 200 to make the accommodating bladder set 200 in the third deformed state, at least part of the accommodating bladders in the accommodating bladder set 200 expand in a direction parallel to the pressing surface. Specifically, each of the accommodating bags is inflated in various directions, and because the accommodating bags in the accommodating bag set 200 are distributed on the pushing surface and are relatively separated, a certain mutual extrusion is generated in the direction parallel to the pushing surface after the accommodating bags are inflated, so that a thrust force from the center to the outer edge is generated in the direction parallel to the pushing surface as a whole, and a required pushing force can be provided for the lamination of the display module and the curved surface part of the curved surface cover plate.
Alternatively, in one possible implementation, the pushing portion 100 may be a hollow structure, and each of the accommodating capsules in the accommodating capsule group 200 is respectively communicated with the pushing portion 100 to form an accommodating chamber. The flow port 300 is provided in the pressing portion 100 and communicates with the accommodating chamber, so that the flowable material can be uniformly filled into or extracted from each of the accommodating cells in the accommodating cell group 200 through the flow port 300.
In another possible implementation, the pushing portion 100 may also include a plurality of flow channels, each of which is respectively connected to each of the receiving pockets of the receiving pocket set 200. The flow-through interface 300 may be connected to each of the flow-through channels such that each of the receptacles in the receptacle set 200 may be uniformly inflated or deflated with flowable material through the flow-through interface 300; or the fitting jig 10 may also include a plurality of circulation interfaces 300, where each circulation interface 300 is respectively connected to each circulation channel, so that each of the accommodation bags in the accommodation bag set 200 may be filled with a flowable material or the flowable material in the accommodation bag may be extracted separately, so as to implement independent control of each accommodation bag.
Optionally, in one possible implementation manner, the accommodating bags are strip-shaped, and an arrangement direction of each accommodating bag in the accommodating bag set 200 is matched with an extension direction of the curved surface portion of the curved surface cover plate. For example, referring to fig. 4, the curved cover plate to be bonded may be a U-shaped curved cover plate, and the curved extension direction thereof extends outwards from two sides of the planar portion. In this case, the accommodation pockets may be distributed in a stripe shape on the pressing surface, and arranged in the same direction as the extending direction of the curved surface portion. In this way, the force parallel to the pushing surface generated by the plurality of the accommodating bag sets when the accommodating bag set 200 is in the third deformation state is also along the extending direction of the curved surface portion, so as to better provide the required pushing force for fitting the curved surface portion.
Optionally, in a possible implementation manner, a shape of a portion of the accommodating pocket along at least one side in an arrangement direction of the plurality of accommodating pockets is similar to a shape of a curved portion of the curved cover plate. For example, referring again to fig. 1, in the set of accommodating pockets 200, the shape of the accommodating pockets at the edges may be arc-shaped and similar to the shape of the curved portion of the curved cover plate.
Optionally, in one possible implementation, the bonding tool 10 may further include a flowable material supply assembly coupled to the flow-through interface 300. The flowable material supply assembly may be an air pump or a liquid pump.
Referring to fig. 5, based on the attaching jig 10 provided in the present embodiment, the present embodiment further provides a method for implementing attaching a curved cover plate and a display module by using the attaching jig 10, where the curved cover plate includes a planar portion and a curved portion, and the method includes:
step S110, extracting the flowable material from the set of accommodating bags 200 through the flow interface 300, so that the set of accommodating bags 200 is in a first deformed state to make adjacent accommodating bags fit to each other.
Specifically, during this process, the amount of flowable material in each of the pockets may be reduced by withdrawing the flowable material from the pocket set 200, thereby allowing each of the pockets to be relatively tightly adsorbed on the pushing surface, having a profile similar to the pushing surface. For example, taking the flowable material in the set of accommodating cells 200 as an example, in the initial state, each of the accommodating cells has a certain amount of gas therein, and when the appropriate amount of gas is extracted, a surface of each of the accommodating cells on a side away from the pressing portion 100 is appropriately collapsed due to a decrease in the amount of gas, so that adjacent accommodating cells are adhered to each other.
Step S120, disposing the display module on the accommodating bag set 200 of the bonding fixture 10.
Referring to fig. 6, in the present embodiment, the flexible display module 20 may be disposed on the accommodating bag set 200 of the bonding fixture 10, and the curved cover 30 may be disposed on a base 40. Alternatively, CF film may be used to pre-deform the display module 20 prior to lamination.
Step S130, controlling the pushing part 100 to drive the display module 20 to move towards the curved cover 30, so that the display module 20 is attached to the planar portion of the curved cover 30.
In this process, the lamination of the display module 20 and the planar portion of the curved cover plate 30 can be achieved.
In step S140, a flowable material is filled into the set of accommodating cells 200 through the flow-through port 300, so that the set of accommodating cells 200 is in a second deformed state, and at least some adjacent accommodating cells are separated from each other along a direction parallel to the pressing surface.
Referring to fig. 7, in this process, an appropriate amount of flowable material may be filled into the accommodating bag set 200, so that each accommodating bag in the accommodating bag set 200 is no longer tightly adsorbed on the pushing surface, and further each accommodating bag is separated from each other along a direction parallel to the pushing surface.
Step S150, continuously filling the flowable material into the set of accommodating bags 200 through the flow interface 300, so that the set of accommodating bags 200 is in a third deformation state, so that at least part of the accommodating bags expand in a direction parallel to the pushing surface, and an attaching force is applied to the display module 20 and the curved cover plate 30 through the accommodating bags.
Referring to fig. 8, in this process, the flowable material may be continuously filled into the set of accommodating bags 200, so that the accommodating bags are inflated and pressed against each other in a direction parallel to the pressing surface, so as to apply a pressing force parallel to the pressing surface to the display module 20, so as to further press the display module 20 against the curved portion of the curved cover 30.
Optionally, in one possible implementation, step S140 may control the pushing portion 100 to move away from the curved cover plate 30 before the flowable material is filled into the accommodating bag set 200 through the flow interface 300 to make the accommodating bag set 200 in the second deformation state, so as to reduce the pushing force applied to the display module 20. In this way, the distance between the storage bag set 200 and the display module 20 can be slightly increased, and the space of each storage bag can be dispersed in the direction parallel to the pressing surface.
Preferably, in step S140, after the flowable material is filled into the accommodating bag set 200 through the flow-through interface 300 to make the accommodating bag set 200 in the second deformation state, the pushing part 100 may be controlled again to drive the display module 20 to move toward the curved cover plate 30.
According to the bonding jig and the bonding method provided by the embodiment of the application, as the bonding jig comprises the containing bag group, the containing bag group comprises a plurality of containing bags which can be separated from each other, and the flowing material can be controlled to flow into or flow out of the containing bag group through the flowing interface, the containing bag group can be in different deformation states, and then acting forces in different directions are applied to the display modules arranged on the containing bags. Therefore, the bonding acting force in different directions can be provided for the curved surface part in the bonding process, so that uneven stress caused by the shape of the curved surface cover plate can be reduced, the possibility of generating bubbles in the bonding process is reduced, and the manufacturing yield of the display panel is improved.
The technical features of the above-described embodiments may be arbitrarily combined, and all possible combinations of the technical features in the above-described embodiments are not described for brevity of description, however, as long as there is no contradiction between the combinations of the technical features, they should be considered as the scope of the description.
