[0039] Curved displays have a beautiful curved appearance, a wide viewing angle, and the distance from each point on the screen to the eye is equal, which can eliminate visual distortion at the edge of the screen and create a natural and comfortable viewing experience. As consumers are increasingly pursuing the appearance and user experience of electronic mobile terminal products, curved glass cover plates have become the mainstream in the electronic product market due to their high light transmittance, novel appearance, and varied colors, which can bring users a visual experience of a larger screen-to-body ratio.

[0040] At present, the bonding between the curved glass cover plate and other components such as the module is mainly achieved by making the curved surface of the curved glass cover plate contact with the bonding surface of the module through the bonding device. However, most of the existing bonding devices are suitable for curved glass whose curved surface area is smaller than the bonding surface area of ​​the module, and curved glass whose chord height is smaller than the thickness of the module. However, the curved surface area of ​​the curved glass in the car B-pillar screen, car instrument and central control, and industrial cold-bent glass screen is larger than the bonding surface area of ​​the module, and the chord height of the curved glass is larger than the thickness of the module, resulting in the existing bonding device being unable to achieve the bonding between the curved glass in the car B-pillar screen, car instrument and central control, and industrial cold-bent glass screen and the module.

[0041] Therefore, there is an urgent need for a curved glass bonding device that can be used for curved glass whose curved surface area is larger than the area of ​​the module bonding surface and whose chord height is larger than the module thickness.

[0042] See also Figure 1-Figure 3 An embodiment of the present application provides a curved glass bonding device for bonding a curved glass 3 and a module 4. The curved glass 3 has a curved surface for bonding with the module 4, and the module 4 has a bonding surface 12 for bonding with the curved glass 3. In the embodiment of the present application, the area of ​​the bonding surface 12 of the module 4 is smaller than the area of ​​the curved surface of the curved glass 3, and the thickness of the module 4 is smaller than the chord height of the curved glass 3.

[0043] In a specific configuration, the curved glass bonding device includes a first fixture 1 and a second fixture 2, and the first fixture 1 and the second fixture 2 are respectively used to position the curved glass 3 and the module 4. The second fixture 2 is detachably arranged on the first fixture 1, so that the module 4 on the second fixture 2 can be bonded with the curved glass 3 on the first fixture 1.

[0044] Specifically, the first fixture 1 is provided with a placement groove 11 for placing the curved glass, and the outer contour of the orthographic projection of the curved glass on the first fixture 1 is consistent with the outer contour of the orthographic projection of the placement groove 11 on the first fixture 1, so that the placement groove 11 can realize the positioning of the curved glass 3 on the first fixture 1.

[0045] A pressing piece 21 for pressing the curved glass is provided on the side of the second jig 2 facing the first jig 1, and the orthographic projection of the pressing piece 21 on the first jig 1 is located in the placement groove 11, so that after the second jig 2 is placed on the first jig 1, the pressing piece 21 on the second jig 2 can press and fix the curved glass, further ensuring the stability of the curved glass on the first jig 1. Specifically, the pressing piece 21 is provided on the side of the second jig 2 facing the first jig 1, and a plurality of pressing pieces 21 are provided, and the plurality of pressing pieces 21 cooperate to achieve stable pressing of the curved glass 3.

[0046] The second jig 2 is also provided with a positioning opening 22 for placing the module 4, and the orthographic projection of the positioning opening 22 on the first jig 1 is located in the placement groove 11. The outer contour of the orthographic projection of the module 4 on the first jig 1 is consistent with the outer contour of the orthographic projection of the positioning opening 22 on the first jig 1. The positioning opening 22 can be used to position the module 4 on the second jig 2, so that the module 4 on the second jig 2 can contact the curved glass, and then the module 4 and the curved glass are bonded. Specifically, the pressing piece 21 is provided with a through opening connected to the positioning opening 22 to ensure that the pressing piece 21 can have a closer distance with the positioning opening 22, so that the pressing piece 21 can press the curved glass 3 close to the module 4, and further ensure the bonding effect between the module 4 and the curved glass 3.

[0047] When in use, the curved glass bonding device of the present application can first place the curved glass in the placement groove 11 of the first fixture 1, so that the placement groove 11 can realize the positioning of the curved glass 3 on the first fixture 1, and then place the second fixture 2 on the first fixture 1, and make the pressing piece 21 on the second fixture 2 abut against the curved glass, further ensuring the stability of the curved glass on the first fixture 1, and then place the module 4 in the positioning port 22 of the second fixture 2, and realize the positioning of the module 4 through the positioning port 22 of the second fixture 2, so that the module 4 on the second fixture 2 can contact the curved glass, and then the module 4 is bonded to the curved glass. In summary, the curved glass bonding device of the present application can realize the positioning of the curved glass on the first fixture 1 by the placement groove 11, and further ensure the stability of the curved glass on the first fixture 1 by pressing the pressing piece 21, and realize the positioning of the module 4 by the positioning port 22 of the second fixture 2, so that the module 4 on the second fixture 2 can contact the curved glass, thereby making the curved surface area larger than the area of ​​the bonding surface 12 of the module 4, and the curved glass 3 whose chord height is larger than the thickness of the module 4 can be firmly bonded with the module 4.

[0048] See also Figure 1 and Figure 3 In one embodiment, the placement groove 11 has a bonding surface 12 facing the second fixture 2, and the first fixture 1 supports the curved glass in the placement groove 11 through the bonding surface 12. The bonding surface 12 is a curved surface consistent with the curvature of the curved glass to ensure the supporting effect of the first fixture 1 on the curved glass in the placement groove 11. The center of the curved surface is away from the first fixture 1, so that after the curved glass is placed in the placement groove 11, the center of the curved glass 3 is away from the first fixture 1, thereby facilitating the subsequent bonding of the curved glass 3 with the module 4.

[0049] Specifically, see Figure 3 and Figure 5 The first fixture 1 has a bottom surface 13 and a mounting surface 14 which are arranged in opposite directions along a first direction, and the second fixture 2 is arranged on the first fixture 1 along the first direction. The bottom surface 13 is the side of the first fixture 1 that contacts the bearing surface (such as the ground, a tabletop, or the surface of other supporting bodies) after being placed, and the mounting surface 14 is the side of the first fixture 1 facing the second fixture 2. The placement groove 11 opens on the mounting surface 14 and extends a distance toward the inside of the first fixture 1 along the first direction. The fitting surface 12 is the side of the placement groove 11 facing the second fixture 2, and the center of the fitting surface 12 faces the opening of the placement groove 11. When the curved glass 3 is placed in the placement groove 11, the side of the curved glass 3 facing away from the opening of the placement groove 11 is fitted with the fitting surface 12, and the center of the curved glass 3 faces the opening of the placement groove 11.

[0050] More specifically, the mounting surface 14 is a curved surface having the same curvature as the bonding surface 12. By making the mounting surface 14 a curved surface having the same curvature as the bonding surface 12, it is convenient to process the curved bonding surface 12 on the first fixture 1.

[0051] See also Figure 1 , Figure 3 and Figure 5 In one embodiment, a support portion 15 for supporting the second fixture 2 is provided on the mounting surface 14, and the support portion 15 can ensure the stability of the second fixture 2 on the arc-shaped mounting surface 14. The support portion 15 has a support surface for supporting the second fixture 2, which is arranged away from the mounting surface 14 and parallel to the bottom surface 13.

[0052] It is understandable that, since the mounting surface 14 is an arc surface, when the second fixture 2 is mounted on the first fixture 1, the second fixture 2 will contact the arc-shaped mounting surface 14, thereby causing a problem of poor stability. Therefore, the present application provides a support portion 15 on the mounting surface 14, and makes the support surface of the support portion 15 for supporting the second fixture 2 parallel to the bottom surface 13, so that after the second fixture 2 is mounted on the first fixture 1, it can also be parallel to the bottom surface 13, and stably supported by the support member, thereby ensuring the stability of the second fixture 2 and the first fixture 1.

[0053] See also Figure 3-Figure 5 In one embodiment, the projection area of ​​the second fixture 2 on the first fixture 1 is smaller than the area of ​​the mounting surface 14, so that the volume of the second fixture 2 can be set to be smaller than the volume of the first fixture 1, which not only saves the production cost of the second fixture 2, but also ensures that after the second fixture 2 is placed on the first fixture 1, the curved glass 3 is not completely blocked by the second fixture 2, and the operator can still easily check the status of the curved glass 3, thereby facilitating operation.

[0054] That is, it can be understood that since the bonding device of the present application is aimed at the use between the curved glass 3 and the module 4 whose curved surface area is larger than the area of ​​the bonding surface 12 of the module 4 and whose chord height is larger than the thickness of the module 4, a larger first fixture 1 and a smaller second fixture 2 can be provided, so that the curved glass 3 with a larger curved surface area can be placed in the first fixture 1 for positioning, and the module 4 with a smaller bonding surface 12 area can be placed in the second fixture 2 for positioning, which can not only save the production cost of the second fixture 2 while ensuring the use effect between the first fixture 1 and the second fixture 2, but also ensure that after the second fixture 2 is placed on the first fixture 1, the curved glass 3 will not be completely blocked by the second fixture 2, and the operator can still easily check the status of the curved glass 3, thereby facilitating operation.

[0055] See also Figure 1-Figure 5In one embodiment, a first positioning structure 16 is provided on the support portion 15, and a second positioning structure 23 is provided on the second fixture 2. The second positioning structure 23 is detachably connected to the first positioning structure 16, so that the second fixture 2 is detachably connected to the first fixture 1. And because the first fixture 1 supports the second fixture 2 through the support portion 15, the stability of the second fixture 2 and the first fixture 1 can be effectively guaranteed by setting the first positioning structure 16 on the support portion 15.

[0056] Specifically, in one embodiment, the first positioning structure 16 is a positioning block provided on the support portion 15, and the second positioning structure 23 is a positioning opening 22 provided on the support portion 15. By inserting the positioning block into the positioning opening 22, a detachable connection between the second positioning structure 23 and the first positioning structure 16 is achieved, thereby making the second fixture 2 detachably connected to the first fixture 1. In another embodiment not shown, the first positioning structure 16 is a positioning groove provided on the support portion 15, and the second positioning structure 23 is a positioning block provided on the support portion 15. By inserting the positioning block into the positioning groove, a detachable connection between the second positioning structure 23 and the first positioning structure 16 is achieved, thereby making the second fixture 2 detachably connected to the first fixture 1.

[0057] To ensure the supporting effect of the support portion 15 on the second fixture 2. In one embodiment, two support portions 15 are provided, and the placement groove 11 is arranged between the two support portions 15 at intervals. The two support portions 15 cooperate with each other to realize the support of the second fixture 2, and ensure the stability of the second fixture 2 on the first fixture 1. Specifically, the second fixture 2 has two fitting portions on the side facing the first fixture 1, and the two fitting portions and the two support portions 15 are arranged one by one along the first direction. The positioning port 22 is arranged between the two fitting portions at intervals. When the second fixture 2 is placed on the first fixture 1, the two fitting portions are distributed and abutted against the two support portions 15 to ensure the stability between the second fixture 2 and the first fixture 1.

[0058] Since the volume of the second fixture 2 is smaller than that of the first fixture 1 and the shape of the module 4 is irregular, the second fixture 2 needs to be placed on the first fixture 1 in the correct direction so that the module 4 and the curved glass 3 can be correctly attached. Therefore, in order to facilitate the confirmation of the direction of the second fixture 2 on the first fixture 1, at least one first positioning structure 16 is provided on each support portion 15, and the number of first positioning structures 16 on the two support portions 15 is different, and at least one second positioning structure 23 is provided on each attachment portion, and the number of second positioning structures 23 on the two attachment portions is different. By having different numbers of first positioning structures 16 on the two support portions 15 and different numbers of second positioning structures 23 on the two attachment portions, the attachment portions with matching numbers can be abutted against the support portions 15, so that the second fixture 2 can be set on the first fixture 1 in the correct direction.

[0059] Specifically, in the embodiment of the present application, one of the supporting parts 15 is provided with a first positioning structure 16, and the other supporting part 15 is provided with two first positioning structures 16, one of the fitting parts is provided with a second positioning structure 23, and the other fitting part is provided with two second positioning structures 23. The supporting part 15 having one first positioning structure 16 cooperates with the fitting part having one second positioning structure 23, and the supporting part 15 having two first positioning structures 16 cooperates with the fitting part having two second positioning structures 23, so that the second fixture 2 can be set on the first fixture 1 in the correct direction.

[0060] See also Figure 2-Figure 4 In order to avoid the fingers holding the module 4 when the module 4 enters the positioning opening 22, in one embodiment, the second fixture 2 is further provided with an avoidance opening 24 connected to the positioning opening 22, and the orthographic projection of the avoidance opening 24 on the first fixture 1 is located in the placement groove 11. In addition, in order to reduce the wear of the edge of the module 4 when it is in the placement groove 11 and reduce the damage, the second fixture 2 is further provided with a surface reduction groove 25, and the positioning opening 22 is arranged in the surface reduction groove 25.

[0061] The embodiment of the present application further provides a curved glass bonding method, which is used in the curved glass bonding device of any one of the above embodiments, and the bonding method includes:

[0062] A curved glass is obtained and placed in a placement groove of a first fixture. Specifically, the placement groove has a bonding surface facing the second fixture, the bonding surface is a curved surface and its center faces the opening of the placement groove. When the curved glass is placed in the placement groove, the side of the curved glass facing away from the opening of the placement groove is bonded to the bonding surface, and the center of the curved glass faces the opening of the placement groove.

[0063] The second jig is placed on the first jig, and the pressing piece on the second jig is brought into contact with the curved glass. Specifically, the pressing piece is arranged on the side of the second jig facing the first jig, and there are multiple pressing pieces, and the multiple pressing pieces cooperate to achieve a stable pressing of the curved glass. Each pressing piece is provided with a through hole connected to the positioning port. This ensures that the pressing piece can be close to the positioning port, so that the pressing piece can press the curved glass close to the module, further ensuring the bonding effect between the module and the curved glass.

[0064] Obtain the module and place it in the positioning opening of the second fixture so that the module is bonded to the curved glass. Specifically, the outer contour of the orthographic projection of the module on the first fixture is consistent with the outer contour of the orthographic projection of the positioning opening on the first fixture, and the positioning opening can be used to position the module on the second fixture so that the module on the second fixture can contact the curved glass, thereby bonding the module to the curved glass.

[0065] When the curved glass bonding method of the present application is applied to the above-mentioned curved glass bonding device, the curved glass is positioned on the first jig by placing a groove, and the stability of the curved glass on the first jig is further ensured by pressing the pressing piece, and the module is positioned by the positioning port of the second jig, so that the module on the second jig can contact the curved glass, thereby making the curved surface area larger than the area of ​​the module bonding surface and the curved glass whose chord height is larger than the module thickness can be firmly bonded to the module.

[0066] 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.

[0067] 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.
