[0001] The utility model relates to the technical field of curved screens, and in particular to a curved screen laminating device. Background Art

[0002] With the continuous development of display technology, in order to bring users a better experience, the screen-to-body ratio of display devices is getting higher and higher, such as curved screens. Since curved screens can provide users with a more immersive viewing effect and greatly enhance the sense of breadth of the user's visual experience, curved screens have developed rapidly. The curved screen includes a display panel and a cover plate. The display panel is usually bonded to the cover plate using SCF (super-clean foam). The current common bonding method is to use a roller to attach the display panel to the cover plate, but because the roller cannot change with the curved surface of the display panel, this causes the roller to be unable to rest against the curved surface of the display panel, making the SCF of the curved surface of the curved screen prone to false bonding problems, affecting the quality of the curved screen.

[0003] Accordingly, the art needs a new technical solution to solve the above problems. Utility Model Content

[0045] Reference Figure 1-2 , the curved screen bonding device of the present application is introduced.

[0046] like Figure 1-2 As shown, in order to improve the problem of SCF false sticking, the curved screen bonding device of the present application includes a first roller unit 1 and a second roller unit 2. The first roller unit 1 corresponds to the curved surface of the curved screen during the use of the curved screen bonding device, and the first roller unit 1 includes an elastic component and a ring mounted on the elastic component, and the ring is configured so that the outermost side of the ring can be commonly attached to the curved surface of the curved screen under the action of the elastic component during the bonding process. The second roller unit 2 is arranged on the end face of the first roller unit 1, and the second roller unit 2 corresponds to the flat surface of the curved screen during the use of the curved screen bonding device.

[0047] The present application is a segmented structure, with the first roller unit 1 corresponding to the curved surface of the curved screen, and the second roller unit 2 corresponding to the plane of the curved screen, so that the wheel ring on the first roller unit 1 can squeeze the elastic component under force and cause the center of gravity to shift, so that the outer side of the wheel ring can always be attached to the curved surface of the curved screen during the use of the curved screen bonding device, thereby solving the problem of SCF on the curved surface of the curved screen being easily attached. The curved screen bonding device of the present application can better adapt to the bending characteristics of the curved screen, improve the bonding effect of the curved screen, and thus improve the quality of the curved screen.

[0048] See below for further reference Figure 1-5 , the preferred implementation manner of the curved screen bonding device of the present application is introduced.

[0049] See also Figure 1-2 The number of the first roller units 1 is 2, and the two first roller units 1 are respectively arranged at the first end of the second roller unit 2 (such as Figure 1The left side of the second roller unit 2 shown) and the second end (as shown Figure 1 The curved screen laminating device is configured as a three-stage structure, so that the second roller unit 2 can correspond to the plane of the curved screen, and the two first roller units 1 can correspond to the curved surfaces on both sides of the length or width direction of the curved screen, thereby improving the working efficiency of the curved screen laminating device. During use, a bearing or a rotating shaft can be set at one end of the two first roller units 1 away from the second roller unit 2, and the curved screen laminating device can be driven to rotate to achieve the installation of the curved screen, thereby avoiding the problem of SCF false lamination on the curved surface of the curved screen.

[0050] Of course, the number of the first roller unit 1 set in the present application is not fixed, and those skilled in the art can adjust it according to the setting needs. For example, the number of the first roller unit 1 can also be 1. When the number of the first roller unit 1 is 1, the first roller unit 1 can be set at the first end or the second end of the second roller unit 2. At this time, in order to facilitate the assembly of the first roller unit 1 and the second roller unit 2 to form a curved screen bonding device, a fifth connecting structure can be set at one end of the first roller unit 1, and a sixth connecting structure that cooperates with the fifth connecting structure is set at the first end or the second end of the second roller unit 2, wherein one of the fifth connecting structure and the sixth connecting structure can be a threaded groove, and the other can be a threaded column that cooperates with the thread of the threaded groove. Alternatively, one of the fifth connecting structure and the sixth connecting structure is a magnetic suction groove, and the other is a magnetic suction column that magnetically cooperates with the magnetic suction groove. Alternatively, one of the fifth connecting structure and the sixth connecting structure is a first magnetic suction sheet, and the other is a second magnetic suction sheet that magnetically cooperates with the first magnetic suction sheet. In addition, when the number of the first roller unit 1 is 1, a bearing or a rotating shaft can be set at the end of the first roller unit 1 away from the second roller unit 2, and at the end of the second roller unit 2 away from the first roller unit 1. The curved screen can be installed by driving the curved screen bonding device to rotate, thereby avoiding the problem of SCF false bonding on the curved surface of the curved screen.

[0051] See next Figure 1-3 The first roller unit 1 includes a first roller 11, which includes a first roller body 111, a first elastic component and a first ring 113. The first elastic component is a first silicone ring 112, which is sleeved on the first roller body 111, and the first silicone ring 112 is sleeved with a first ring 113. The first ring 113 is attached to the end face of the second roller unit 2 corresponding thereto, that is, the first roller 11 located at the first end of the second roller unit 2 is attached to the first end of the second roller unit 2, and the first roller 11 located at the second end of the second roller unit 2 is attached to the second end of the second roller 21, thereby solving the problem that the first roller 11 is only in contact with the second roller unit 2 in the axial direction (such as Figure 1 The existence of gaps in the X direction (shown) causes the problem of SCF virtual sticking.

[0052] In the exemplary embodiment, the number of the first rollers 11 is not fixed, and those skilled in the art can adjust it according to the setting needs. For example, the number of the first rollers 11 is 2, 3 or other numbers. When the number of the first rollers 11 is 2 or more, in the first roller unit 1 located at the first end of the second roller unit 2, a plurality of first rollers 11 are sequentially arranged along the first end of the second roller unit 2 in the axial direction, and in the second roller unit 2 located at the second end of the second roller unit 2, a plurality of second rollers 21 are sequentially arranged along the second end of the second roller unit 2 in the axial direction. And by setting a plurality of first rollers 11, the curved screen laminating device can adjust the number of first rollers 11 according to the size of the curved screen. Taking two first rollers 11 as an example, when the size of the curved surface of the curved screen is large, two first rollers 11 can be used, and when the size of the curved surface of the curved screen is small, one first roller 11 can be used to solve the problem of SCF virtual laminating in curved screens of different sizes. In addition, the number of the two first roller units 1 can be the same or different. For example, the number of the first roller 11 in the first roller unit 1 located at the first end of the second roller unit 2 may be 1, and the number of the first roller 11 in the first roller unit 1 located at the second end of the second roller unit 2 may be 2. Alternatively, the number of the first roller 11 in the first roller units 1 at both ends of the second roller unit 2 is 1, 2, or another number.

[0053] In an exemplary embodiment, when the number of the first rollers 11 is two or more, in order to facilitate the assembly of the plurality of first rollers 11 to form the first roller unit 1, at both ends of each first roller 11 (such as Figure 3The first connecting structure and the second connecting structure are respectively provided on the left and right sides (shown), and the first connecting structure cooperates with the second connecting structure. At this time, in order to assemble the first roller unit 1 and the second roller unit 2, the first connecting structure or the second connecting structure can be independently provided at the first end and the second end of the second roller unit 2, as long as a first roller 11 close to the second roller unit 2 can be installed on the second roller unit 2. In addition, when the number of the first roller 11 is 1, the first connecting structure and the second connecting structure can also be provided at both ends of the first roller 11, or the first connecting structure can be provided at one end where the first roller 11 is connected to the second roller unit 2, and the second connecting structure is provided on the second roller unit 2, or the second connecting structure is provided at one end where the first roller 11 is connected to the second roller unit 2, and the first connecting structure is provided on the second roller unit 2. In the above, one of the first connecting structure and the second connecting structure can be a thread groove, and the other can be a thread column threadedly matched with the thread groove. Alternatively, one of the first connecting structure and the second connecting structure is a magnetic suction groove, and the other is a magnetic suction column magnetically matched with the magnetic suction groove. Alternatively, one of the first connecting structure and the second connecting structure is a first magnetic sheet, and the other is a second magnetic sheet that magnetically cooperates with the first magnetic sheet.

[0054] In the exemplary embodiment, the first elastic component is not necessarily configured in a unique manner, as long as it can cause the center of gravity of the first wheel ring 113 to shift when subjected to force. For example, the first elastic component can also be a rubber ring, which is sleeved on the first roller body 111. Or, Figure 4 As shown, the first elastic component may include a plurality of first silicone rubbers 114 disposed on the outer wall of the first roller body 111, and the plurality of first silicone rubbers 114 are spaced apart along the circumference of the first roller body 111. Alternatively, the first elastic component may include a plurality of rubbers or springs disposed on the outer wall of the first roller body 111, and the plurality of rubbers or springs are spaced apart along the circumference of the first roller body 111.

[0055] In an exemplary embodiment, the first ring 113 may be made of a rigid material, and its center of gravity may shift under the action of the first elastic component, so that the outer side of the first ring 113 can always be in contact with the curved surface of the curved screen during use of the curved screen fitting device.

[0056] See next Figure 1-3A first mounting groove 1111 is provided on the outer wall of the first roller body 111. The cross-sectional shape of the first mounting groove 1111 is rectangular. The first silicone ring 112 is provided in the first mounting groove 1111. The axial length thereof is adapted to the first mounting groove 1111 to facilitate deformation of the first silicone ring 112 under force. The cross section of the first wheel ring 113 is T-shaped, and it includes a first rod segment 1131 and a first cap segment 1132, both of which have rectangular cross sections, wherein the first rod segment 1131 is sleeved on the first silicone ring 112, and part of the first rod segment 1131 extends out of the first mounting groove 1111, and part of it is arranged in the first mounting groove 1111, and the first cap segment 1132 is sleeved on the outer wall of the first rod segment 1131, so that when the first cap segment 1132 is subjected to force, the first rod segment 1131 can squeeze the first silicone to drive the first cap segment 1132 to shift its center of gravity, so that the outer side surface of the first cap segment 1132 can always be attached to the curved surface of the curved screen during the use of the curved screen bonding device, thereby solving the problem that the SCF of the curved surface of the curved screen is prone to false bonding. Among them, the dimension L1 of the first cap segment 1132 in the axial direction is greater than the dimension L2 of the first rod segment 1131 in the axial direction, and one end of the first cap segment 1132 in the axial direction abuts against the end face of the second roller unit 2 corresponding to it (such as Figure 2 The first rod section 1131 extends out of the mounting groove in the radial direction (as shown in the figure) and the second roller unit 2 in the figure) to solve the problem of SCF virtual sticking caused by the gap between the first roller unit 1 and the second roller unit 2 in the axial direction. Figure 1 The dimension H1 in the Y direction (as shown) is greater than or equal to the radial deformation of the first silicone ring 112, which can increase the offset of the center of gravity caused by the first ring 113 squeezing the first silicone ring 112, improve the fitting effect of the curved screen, and help solve the problem of false sticking of the SCF on the curved surface of the curved screen.

[0057] In an exemplary embodiment, the radial length of the first silicone ring 112 may also be equal to the depth of the first mounting groove 1111 in the radial direction, or may also be greater than the depth of the first mounting groove 1111 in the radial direction. When the radial length of the first silicone ring 112 is greater than the depth of the first mounting groove 1111, part of the first silicone ring 112 is disposed in the first mounting groove 1111, and part of the first silicone ring 112 extends out of the first mounting groove 1111, and at this time, the first rod segment 1131 is completely disposed outside the first roller body 111.

[0058] In an exemplary embodiment, the cross section of the first wheel ring 113 may also be an inverted L-shape or other shapes. In addition, the cross-sectional shape of the first rod segment 1131 and the first cap segment 1132 in the first wheel ring 113 may not be limited to a rectangle. The cross-sectional shape of the first rod segment 1131 and the first cap segment 1132 may also be a trapezoid, or other regular or regular shapes, as long as the first rod segment 1131 can squeeze the first silicone ring 112 and the first cap segment 1132 can be abutted against the end face of the second roller unit 2 corresponding thereto. In addition, the cross-sectional shape of the first mounting groove 1111 may also be a trapezoid with a long notch and a short bottom, or other regular or irregular shapes, as long as it is conducive to the deformation of the first elastic component. When the first mounting groove 1111 is other regular or irregular shapes, the overall size of the first rod segment 1131 in the axial direction is less than or equal to the overall size of the first mounting groove 1111 in the axial direction, that is, the maximum size of the first rod end in the axial direction is less than or equal to the minimum size of the first mounting groove 1111 in the axial direction.

[0059] In an exemplary embodiment, the present application has no restrictions on the arrangement of the first mounting groove 1111, as long as it can prevent the first silicone ring 112 from detaching from the first roller body 111 during use. For example, one end of the first mounting groove 1111 on the first roller 11 in the axial direction can extend to the side of the first roller body 1111 close to the second roller unit 2. When one end of the first mounting groove 1111 of the first roller unit 1 in the axial direction extends to the side of the first roller body 1111 close to the first roller unit 1, the first mounting groove 1111 and the end surface of the second roller unit 2 can form a space for accommodating the first elastic component, thereby preventing the curved screen laminating device from detaching from the first roller body 111 during use. It should also be noted that when the number of first rollers 11 is 2 or more, except for a first roller 11 close to the second roller unit 2, the first mounting grooves 1111 on the remaining first rollers 11 and the end surfaces of the adjacent first rollers 11 form a space for accommodating the silicone ring.

[0060] See next Figure 1-2 5, the second roller unit 2 includes 6 second rollers 21 arranged in sequence axially, and the first end (such as Figure 5 The left side shown in FIG. 1 is provided with a third connection structure, and the second end (such as Figure 5The fourth connection structure is provided on the right side of the figure, and the third connection structure on any second roller 21 is connected with the fourth connection structure on the adjacent second roller 21. Among them, the third connection structure is a threaded groove 2113, and the fourth connection structure is a threaded column 2112 that is threadedly matched with the threaded groove 2113. The connection method of the threaded groove 2113 and the threaded column 2112 is adopted to facilitate the installation and disassembly of the second roller unit 2 formed by assembling multiple second rollers 21. The second roller unit 2 is arranged as a segmented structure to adapt to curved screens of different sizes and specifications. For example, when the size of the curved screen plane is larger, 4, 5 or 6 second rollers 21 can be used. When the size of the curved screen plane is smaller, 1, 2 or 3 second rollers 21 can be used to solve the problem of SCF virtual sticking in curved screens of different sizes and specifications. When the first end of the second roller 21 is provided with a threaded groove 2113 and the second end face is provided with a threaded column 2112, the end face of the first roller unit 1 located at the first end of the second roller 21 (such as Figure 2 A threaded column 1112 that cooperates with the thread groove 2113 is provided on the right side of the first roller unit 1 shown in the figure. The end surface of the first roller unit 1 located at the second end of the second roller 21 (as shown in the figure) Figure 2 A thread groove 1113 matching with the thread column 2112 is provided on the left side of the first roller unit 1 shown.

[0061] In an exemplary embodiment, the third connection structure and the fourth connection structure are not unique in their arrangement, and the following arrangement can also be used, as long as a plurality of second rollers 21 are assembled to form the second roller unit 2. For example, the third connection structure is a threaded column, and the fourth connection structure is a threaded groove that is threadedly matched with the threaded column. Alternatively, one of the third connection structure and the fourth connection structure is a magnetic suction groove, and the other is a magnetic suction column that is magnetically matched with the magnetic suction groove. Alternatively, one of the third connection structure and the fourth connection structure is a first magnetic suction sheet, and the other is a second magnetic suction sheet that is magnetically matched with the first magnetic suction sheet.

[0062] In an exemplary embodiment, the number of the second rollers 21 in the second roller unit 2 may also be 1, 2 or other numbers. Taking 1 second roller 21 as an example, when the number of the second roller 21 is 1, in order to facilitate the installation of the two first roller units 1 at the first end and the second end of the second roller 21, a fifth connection structure may be provided at the first end of the second roller 21, and a seventh connection structure may be provided at the second end, and a sixth connection structure matched with the fifth connection structure may be provided on the first roller 11 located at the first end of the second roller unit 2, and an eighth connection structure matched with the seventh connection structure may be provided on the first roller 11 located at the second end of the second roller unit 2. In the above-mentioned setting, one of the fifth connection structure and the seventh connection structure is a thread groove and the other is a thread matched with the thread groove, or one of the fifth connection structure and the seventh connection structure is a magnetic suction groove and the other is a magnetic suction column matched with the magnetic suction groove, or one of the fifth connection structure and the seventh connection structure is a first magnetic suction sheet and the other is a second magnetic suction sheet matched with the first magnetic suction sheet. And / or, one of the sixth connection structure and the eighth connection structure is a thread groove and the other is a thread column that is threadedly matched with the thread groove; or one of the sixth connection structure and the eighth connection structure is a magnetic suction groove and the other is a magnetic suction column that is magnetically matched with the magnetic suction groove; or one of the sixth connection structure and the eighth connection structure is a first magnetic suction sheet and the other is a second magnetic suction sheet that is magnetically matched with the first magnetic suction sheet. In other words, the fifth connection structure and the seventh connection structure can be the same or different, and the sixth connection structure and the eighth connection structure are the same, such as the fifth connection structure and the seventh connection structure are both thread grooves, and the sixth connection structure and the eighth connection structure are both thread grooves.

[0063] See next Figure 1-2 5, the second roller 21 includes a second roller body 211, a second elastic component and a second ring 213. The first end of the second roller body 211 is provided with a third connection structure, the second end is provided with a fourth connection structure, and the second elastic component is a second silicone ring 212, which is sleeved on the second roller body 211. Under stress, the second ring 213 can squeeze the second silicone ring 212 to shift the center of gravity, so that the outer side of the second ring 213 can always be attached to the curved screen during the use of the curved screen bonding device.

[0064] In the exemplary embodiment, the second elastic component is not uniquely provided, as long as the second elastic component can drive the second ring 213 to shift its center of gravity when subjected to force. For example, the second elastic component can also be a rubber ring, which is sleeved on the second roller body 211. Alternatively, the second elastic component can include a plurality of silicones, rubbers or springs provided on the outer wall of the second roller body 211, and the plurality of silicones, rubbers or springs are distributed at intervals along the circumference of the second roller body 211. In addition, in other preferred embodiments, the second elastic component is not required, and those skilled in the art can make a selection according to the setting requirements.

[0065] In an exemplary embodiment, the second ring 213 may be made of a rigid material, and its center of gravity may shift under the action of the second elastic component, which facilitates the connection between the display panel and the cover plate through the SCF.

[0066] See next Figure 1-2 5. A second mounting groove 2111 is provided on the outer wall of the second roller body 211. The cross-sectional shape of the second mounting groove 2111 is rectangular. The second silicone ring 212 is provided in the second mounting groove 2111. Its axial length is adapted to the second mounting groove 2111, so as to facilitate the deformation of the second silicone ring 212 under stress. The cross-sectional shape of the second wheel ring 213 is T-shaped, and it includes a second rod segment 2131 and a second cap segment 2132, both of which are rectangular in cross-sectional shape. The second rod segment 2131 is sleeved on the second silicone ring 212, and part of the second rod segment 2131 extends out of the second mounting groove 2111, and part of the second rod segment 2131 is provided in the second mounting groove 2111. The second cap segment 2132 is sleeved on the outer wall of the second rod segment 2131, so that when the second cap segment 2132 is subjected to stress, the second rod segment 2131 can squeeze the second silicone ring 212 to drive the second cap segment 2132 to shift its center of gravity. The dimension L3 of the second cap segment 2132 in the axial direction is greater than the dimension L4 of the second rod segment 2131 in the axial direction, and the axial end surface (such as Figure 5 The left and right sides shown in the figure are in abutment with each other, and one end of the second roller 21 close to the first roller unit 1 in the axial direction abuts against the end face of the first roller unit 1 corresponding thereto, thereby solving the problem of SCF virtual sticking caused by the gap between the first roller unit 1 and the second roller unit 2 in the axial direction. The radial dimension H2 of the portion of the second rod segment 2131 extending out of the second mounting groove 2111 is greater than or equal to the radial deformation of the second silicone ring 212, thereby increasing the offset of the center of gravity offset caused by the second ring 213 squeezing the second silicone ring 212.

[0067] In an exemplary embodiment, the radial dimension of the second silicone ring 212 may also be equal to the radial depth of the second mounting groove 2111, or may be greater than the radial depth of the second mounting groove 2111. When the radial length of the second silicone ring 212 is greater than the depth of the second mounting groove 2111, part of the second silicone ring 212 is disposed in the second mounting groove 2111, and part of the second silicone ring 212 extends out of the second mounting groove 2111, and at this time, the second rod segment 2131 is completely disposed outside the second roller body 211.

[0068] In an exemplary embodiment, the cross section of the second wheel ring 213 may also be an inverted L-shape or other shapes. In addition, the cross-sectional shape of the second rod segment 2131 and the second cap segment 2132 in the second wheel ring 213 may not be limited to a rectangle. The cross-sectional shape of the second rod segment 2131 and the second cap segment 2132 may also be a trapezoid, or other regular or regular shapes, as long as the second rod segment 2131 can squeeze the second silicone ring 212, the adjacent second cap segments 2132 are abutted against each other, and the second cap segment 2132 can be abutted against the end face of the first roller unit 1 corresponding thereto. In addition, the cross-sectional shape of the second mounting groove 2111 may also be a trapezoid with a long notch and a short groove bottom, or other regular or irregular shapes, as long as it is conducive to the deformation of the second elastic component. When the second mounting groove 2111 is other regular or irregular shapes, the overall dimension of the second rod segment 2131 in the axial direction is less than or equal to the overall dimension of the second mounting groove 2111 in the axial direction, that is, the maximum dimension of the second rod segment 2131 in the axial direction is less than or equal to the minimum dimension of the second mounting groove 2111 in the axial direction.

[0069] In an exemplary embodiment, the present application has no limitation on the setting form of the second mounting groove 2111, as long as it can prevent the second silicone ring 212 from detaching from the second roller body 211 during use. For example, one end of the second mounting groove 2111 on the second roller body 211 in the axial direction extends to the first end or the second end of the second roller body 211. Take the example that one end of the second mounting groove 2111 on the second roller body 211 in the axial direction extends to the second end of the second roller body 211 as an example. At this time, the first end of the second roller body 211 corresponds to the first end of the second roller unit 2, the second end of the second roller body 211 corresponds to the second end of the second roller unit 2, and the second mounting groove 2111 on the second roller 21 at the second end of the second roller unit 2 corresponds to the end surface of the first roller unit 1 at the second end of the second roller unit 2 (such as Figure 1The left side of the first roller unit 1 shown in the figure can form a space for accommodating the second silicone ring 212 to prevent the second silicone ring 212 from detaching from the second roller body 211 during use of the curved screen bonding device, and a space for accommodating the second elastic component is formed between the second mounting groove 2111 on the remaining second rollers 21 and the end face of the second roller 21 adjacent thereto. At this time, in order to ensure that the first roller units 1 at both ends of the second roller unit 2 can form a space for accommodating the first elastic component, the first mounting groove 111 on the first roller 11 at the first end of the second roller unit 2 can have one end in the axial direction extending to the end face of the first roller body 111, and both ends in the axial direction of the first mounting groove 1111 on the first roller 11 at the second end of the second roller unit 2 are closed ends.

[0070] In the exemplary embodiment, since the second roller unit 2 corresponds to the plane of the curved screen, when the second elastic component is not provided, the second mounting groove 2111 and / or the second ring 213 may not be provided. When the second elastic component, the second mounting groove 2111 and the second ring 213 are not provided, the second ring 213 may be formed only by the second roller body 211.
