DETAILED DESCRIPTION

[0067] In order to make the objectives, technical solutions and advantages of the present application more clearly understood, the present application is further described in detail below in combination with specific embodiments and with reference to the accompanying drawings.

[0068] It should be noted that, unless otherwise defined, the technical terms or scientific terms used in the embodiments of the present application should be the usual meanings understood by people with ordinary skills in the field to which the present application belongs.

"Up", "down", "left", "right" and the like are only used to indicate relative positional relationships. When the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0069] In the related art, a flexible display panel is generally attached to a curved cover plate by an attaching device. Figure 1 As shown, the attaching device includes a first carrier 11, a second carrier 12 and a profiling jig 10, a first sticker 101 is detachably fixed on the first carrier 11, and the second carrier 12 carries a second sticker 102 through the profiling jig 10, wherein the profiling jig 10 includes a profiling pad made of silicone material, specifically, the first sticker 101 includes a curved cover plate, and the second sticker 102 includes a flexible display panel. During the attaching process, the first carrier 11 and the second carrier 12 are moved relative to each other, and the profiling jig 10 squeezes the first sticker 101 and the second sticker 102 from the side of the second sticker 102 away from the first sticker 101, and the second sticker 102 is stretched and bent to match the shape of the first sticker 101, so as to complete the 3D bonding of the first sticker 101 and the second sticker 102 to form a curved screen.

[0070] The inventor has found through research that the current attachment device needs to replace the first carrier 11 and the profiling fixture 10 when attaching curved screens of different sizes, which wastes manpower, material resources and financial resources. In particular, the fixtures on the experimental line will be replaced more frequently, resulting in an increase in sample production costs.

[0071] Based on this, the present application provides an attachment device solution to improve the versatility of the attachment device and reduce the replacement frequency.

[0072] Reference Figures 2 to 6As shown, an attaching device 100 provided in an embodiment of the present application includes a first carrier 11, wherein the first carrier 11 includes a first main body portion 111, and a fixed portion 112 and a movable portion 113 are provided on the first main body portion 111. The movable portion 113 can move along a first direction (X direction in the figure) to adjust the distance between the movable portion 113 and the fixed portion 112. The first main body portion 111 includes a first plane 1110, the fixed portion 112 includes a first curved surface 1120, and the movable portion 113 includes a second curved surface 1130. The first plane 1110, the first curved surface 1120 and the second curved surface 1130 enclose a receiving groove 110 for receiving the first object 101.

[0073] The attaching device 100 provided in the embodiment of the present application can adapt to first objects 101 of different sizes by adjusting the distance between the moving part 113 and the fixed part 112 of the first carrier 11, thereby adjusting the width of the accommodating groove 110 in the first direction X. On the premise that the curvature of the curved surface portion of the first object 101 remains unchanged, the distance between the moving part 113 and the fixed part 112 can be adjusted to adapt to first objects 101 of different sizes without frequently replacing the first carrier 11, thereby improving the versatility of the attaching device 100 and reducing the replacement frequency.

[0074] In one embodiment, the attaching device 100 further includes a second carrier 12, the second carrier 12 includes a second plane 120, the second plane 120 is a surface of the second carrier 12 close to the receiving groove 110, and the second plane 120 is used to carry the second adhesive 102. The second carrier 12 is relatively close to the receiving groove 110, and the second adhesive 102 on the second carrier 12 can be attached to the flat surface part and the curved surface part of the first adhesive 101 in the receiving groove 110 to form a curved screen.

[0075] In one embodiment, the attaching device 100 further includes a first pressing mechanism 13 and a second pressing mechanism 14. The first pressing mechanism 13 is used to drive the second stage 12 and the first stage 11 to move relative to each other along the second direction (Z direction in the figure) until the second object 102 is attached to the portion of the first object 101 corresponding to the first plane 1110; the second pressing mechanism 14 can move along the first direction X to apply pressure to the portion of the second object 102 corresponding to the first curved surface 1120 and the second curved surface 1130. The first direction X is parallel to the first plane 1110, and the second direction Z is perpendicular to the first plane 1110.

[0076] Specifically, the first pressing mechanism 13 drives the second platform 12 and the first platform 11 to move relative to each other along the second direction Z, so that the second platform 12 approaches the receiving groove 110, and under the pressure of the first pressing mechanism 13, the second object 102 is partially bonded with the first object 101 corresponding to the first plane 1110, and the second pressing mechanism 14 moves along the first direction X so that the curved surface parts of the second object 102 and the first object 101 are pressed and bonded, thereby completing the entire bonding between the second object 102 and the first object 101; the position of the second pressing mechanism 14 in the first direction X is adjustable, and can adapt to second objects 102 of different sizes.

[0077] In one embodiment, the second pressing mechanism 14 can move in the first direction X and the second direction Z simultaneously, so that when pressing the curved surface portion, the movement trajectory of the second pressing mechanism 14 can automatically adapt to the shapes of the first curved surface 1120 and the second curved surface 1130 .

[0078] In other embodiments, the second pressing mechanism 14 only moves along the first direction X, and at the same time, the first pressing mechanism 13 moves along the second direction Z, so as to achieve pressing of the curved surface portion.

[0079] In the embodiment of the present application, the first direction X corresponds to the left-right direction, the second direction Z corresponds to the up-down direction, and the third direction Y corresponds to the front-back direction for description.

[0080] In the attaching device 100 provided in this embodiment, the first adhesive 101 is fixed in the receiving groove 110 of the first carrier 11, and specifically, the first adhesive 101 can be detachably fixed in the receiving groove 110 by vacuum adsorption or bonding, and the notch of the receiving groove 110 faces downward. When the moving part 113 and the fixing part 112 are located at both ends of the first main body 111, the width of the receiving groove 110 is the maximum width, and when the moving part 113 moves a distance b on the first main body 111, the width dimension of the receiving groove 110 changes to b. The second adhesive 102 is placed in a flat form on the second plane 120 of the second carrier 12. The first pressing mechanism 13 can be located below the second carrier 12, thereby driving the second carrier 12 to move up and down; the first pressing mechanism 13 can also be located above the first carrier 11, thereby driving the first carrier 11 to move up and down. In short, the first pressing mechanism 13 can change the distance between the second carrier 12 and the first carrier 11. The first pressing mechanism 13 mainly applies pressure to the planar part of the second adhesive 102 and the first adhesive 101 to achieve the bonding of the planar parts.

[0081] Specifically, during or after the process of applying pressure to the flat part of the second adhesive 102 and the first adhesive 101, the second pressing mechanism 14 can move in the up-down direction and the left-right direction, so as to apply pressure to the curved part of the second adhesive 102 and the first adhesive 101; of course, the second pressing mechanism 14 can also be moved only in the left-right direction, while the first carrier 11 is moved up-down or rotated up-down, so as to achieve the same pressure application on the curved part of the second adhesive 102 and the first adhesive 101, until the second adhesive 102 and the first adhesive 101 are fully attached. Among them, the width of the receiving groove 110 is adjustable, and the position of the second pressing mechanism 14 in the left-right direction is adjustable, so as to adapt to the attachment of curved screens of different sizes, and the pressure of the first pressing mechanism 13 and the second pressing mechanism 14 ensures that the entire area of ​​the bonding surface of the second adhesive 102 and the first adhesive 101 has a good bonding effect, thereby ensuring the display quality.

[0082] Preferably, there are two second pressing mechanisms 14, which are respectively arranged on opposite sides of the first pressing mechanism 13 along the first direction X. Among them, through two independently controllable second pressing mechanisms 14, two parts of the second adhesive 102 corresponding to the first curved surface 1120 and the second curved surface 1130 can be pressed at the same time, thereby improving the attachment efficiency. Alternatively, one second pressing mechanism 14 is used to press the part of the second adhesive 102 corresponding to the first curved surface 1120, and then another second pressing mechanism 14 is used to press the part of the second adhesive 102 corresponding to the second curved surface 1130.

[0083] In other embodiments, there is one second pressing mechanism 14 disposed on one side of the first pressing mechanism 13 along the first direction X. After the second pressing mechanism 14 partially presses the first curved surface 1120 , the second pressing mechanism 14 is moved to the bottom of the second curved surface 1130 to press it.

[0084] Specifically, the two second pressing mechanisms 14 are located on both sides of the first pressing mechanism 13 in the first direction X, that is, the two second pressing mechanisms 14 are located on the left and right sides of the first pressing mechanism 13 and are symmetrically distributed.

[0085] Reference Figure 2 , Figure 7 As shown, in one embodiment, the attaching device 100 further includes a rotating mechanism 15, the rotation axis of the rotating mechanism 15 extends along the third direction Y, and is used to drive the first carrier 11 and the second pressing mechanism 14 to rotate relative to each other. The third direction Y is perpendicular to the first direction X and the second direction Z.

[0086] Preferably, the rotating mechanism 15 is disposed on the first carrier 11. Wherein, the rotating mechanism 15 is disposed on the first carrier 11, and the load of the rotating action is relatively small, which is easier to achieve. Further, the rotating mechanism 15 can drive the first carrier 11 to rotate from the initial position to the first angle a.

[0087] Among them, the first angle a includes an angle of 0-30 degrees with the plane where the initial position is located, and the first stage 11 located at the initial position can be parallel to the second stage 12. For example, the first angle a can be a smaller angle such as 0 degrees, 3 degrees, 5 degrees, 10 degrees, 30 degrees, etc. When the first angle a is 0 degrees, the first stage 11 is located at the initial position. For example, after the first stage 11 rotates, the middle section of the first curved surface 1120 or the second curved surface 1130 faces directly downward. In this way, the movement range of the second pressing mechanism 14 in the second direction Z can be relatively reduced, that is, the stroke of the second pressing mechanism 14 in the up and down directions can be reduced.

[0088] Reference Figure 5 As shown, in one embodiment, the attaching device 100 further includes a first driving component 16 and a second driving component 17. The first driving component 16 drives the first pressing mechanism 13 and the second pressing mechanism 14 to move along the first direction X, and the second driving component 17 drives the first pressing mechanism 13 and the second pressing mechanism 14 to move along the second direction Z. The first pressing mechanism 13 and the second pressing mechanism 14 can move in two directions, and the positions of the first pressing mechanism 13 and the second pressing mechanism 14 relative to the receiving groove 110 can be quickly adjusted. The pressure position of the second adhesive 102 and the first adhesive 101 can also be adjusted according to the width adjustment of the receiving groove 110. For example, the middle position of the first pressing mechanism 13 is aligned with the middle position of the receiving groove 110, and the first pressing mechanism 13 and the second pressing mechanism 14 are driven by the second driving component 17 to move upward at the same time so that the first pressing mechanism 13 and the second pressing mechanism 14 and the second stage 12 are close to the receiving groove 110, so as to apply pressure to the second adhesive 102 and the first adhesive 101 for bonding.

[0089] Preferably, refer to Figure 2 , Figure 5 As shown, the attaching device 100 further includes a third driving assembly 21, which is used to drive the first pressing mechanism 13 to move along the third direction Y. In this embodiment, the third direction Y corresponds to the front-back direction, and during the movement of the first pressing mechanism 13 along the third direction Y, the second adhesive 102 and the plane part of the first adhesive 101 can be evenly and comprehensively pressed.

[0090] Preferably, refer to Figure 2 , Figure 5As shown, the attaching device 100 also includes a support platform 20, a first pressing mechanism 13 and a second pressing mechanism 14 are arranged on the support platform 20, the first driving component 16 can drive the support platform 20 to move along the first direction X, and the second driving component 17 is used to drive the support platform 20 to move along the second direction Z.

[0091] Optionally, refer to Figure 6 As shown, for the convenience of understanding the top view, the first pressing mechanism 13 is shown as being moved to the outside of the second stage 12, that is, the orthographic projection of the first pressing mechanism 13 on the plane where the second stage 12 is located is located outside the second stage 12. During operation, the first pressing mechanism 13 is located below the second stage 12, that is, the orthographic projection of the first pressing mechanism 13 on the plane where the second stage 12 is located is located inside the second stage 12. After the first pressing mechanism 13 presses the planar portion of the second object 102 and the first object 101, the first pressing mechanism 13 supports the second stage 12, and then the first driving assembly 16 can drive the second pressing mechanism 14 to move along the first direction X and the second direction Z to press the curved surface portion of the second object 102 and the first object 101.

[0092] Alternatively, in some other embodiments, the number of first drive components 16 may be the same as the total number of first pressing mechanisms 13 and second pressing mechanisms 14, and correspond one to one, that is, each first drive component 16 individually drives a first pressing mechanism 13 or a second pressing mechanism 14 to move along the first direction X; the number of second drive components 17 may be the same as the total number of first pressing mechanisms 13 and second pressing mechanisms 14, and correspond one to one, that is, each second drive component 17 individually drives a first pressing mechanism 13 or a second pressing mechanism 14 to move along the second direction Z.

[0093] Reference Figure 6 As shown, in one embodiment, the first pressing mechanism 13 includes a first roller 131, and the rotation axis of the first roller 131 extends along the first direction X; the second pressing mechanism 14 includes a second roller 141, and the rotation axis of the second roller 141 extends along the third direction Y.

[0094] Preferably, the first roller 131 can move along the second direction Z and the third direction Y respectively, that is, the first roller 131 can move along the up-down direction and the front-back direction, and can realize the rolling pressing action on the plane part.

[0095] Preferably, the second roller 141 can move along the first direction X and the second direction Z respectively, that is, the second roller 141 can move along the left-right direction and the up-down direction, so as to realize the rolling pressing action on the curved surface part.

[0096] The roller structure is used to roll the second adhesive 102 onto the first adhesive 101, so that bubbles are not easily generated during the bonding process, especially the second adhesive 102 and the curved surface part of the first adhesive 101 have a better bonding effect, which helps to improve the bonding quality.

[0097] In other embodiments, in addition to the roller structure, the first pressing mechanism 13 and the second pressing mechanism 14 may also adopt other curved surface structures or planar structures to achieve corresponding pressing actions.

[0098] Reference Figure 5 As shown, in one embodiment, the attaching device 100 further includes a first attaching driving member 18 and a second attaching driving member 19, wherein the first attaching driving member 18 is connected to the first pressing mechanism 13, and is used to drive the first pressing mechanism 13 to move along the second direction Z; the second attaching driving member 19 is connected to the second pressing mechanism 14 in a one-to-one correspondence, and the second attaching driving member 19 is used to drive the second pressing mechanism 14 to move along the second direction Z. Among them, the attaching pressure of the first pressing mechanism 13 and the second pressing mechanism 14 can be controlled by the first attaching driving member 18 and the second attaching driving member 19, respectively, and the pressure strength of the plane part of the second adhesive 102 and the first adhesive 101 and the curved part of the second adhesive 102 and the first adhesive 101 can be adjusted to improve the attaching quality. In general, the first drive assembly 16 and the second drive assembly 17 mainly perform rough adjustment on the position of each attaching mechanism, and the first attaching driving member 18 and the second attaching driving member 19 focus on fine adjustment and pressure adjustment of each attaching mechanism.

[0099] Specifically, the first laminating drive member 18 is directly connected to the first roller 131, and the second laminating drive member 19 is directly connected to the second roller 141.

[0111] The present embodiment provides an attaching method, in which the distance between the moving part 113 and the fixed part 112 of the first carrier 11 is adjustable, so as to adapt to first objects 101 of different sizes. On the premise that the curvature of the curved surface portion of the first object 101 remains unchanged, the distance between the moving part 113 and the fixed part 112 can be adjusted to adapt to first objects 101 of different sizes without frequently replacing the first carrier 11, thereby improving the versatility of the attaching device 100 and reducing the replacement frequency.

[0112] In one embodiment, step S2 includes:

[0113] The first pressing mechanism 13 moves along the second direction Z, driving the second carrier 12 and the first carrier 11 to move relative to each other.

[0114] Step S3 includes: using the second pressing mechanism 14 to move at least along the first direction X to apply pressure to the portion of the second adhesive 102 corresponding to the first curved surface 1120 and the second curved surface 1130 .

[0115] Preferably, there are two second pressing mechanisms 14 , which are respectively disposed on two opposite sides of the first pressing mechanism 13 along the first direction X.

[0116] One second pressing mechanism 14 can press the portion of the second adhesive 102 corresponding to the first curved surface 1120, and another second pressing mechanism 14 can press the portion of the second adhesive 102 corresponding to the second curved surface 1130. The two second pressing mechanisms 14 can work sequentially or simultaneously under the premise of independent control.

[0117] Alternatively, there is one second pressing mechanism 14, which is disposed on one side of the first pressing mechanism 13 along the first direction X. After the second pressing mechanism 14 applies pressure to the portion of the second adhesive 102 corresponding to the first curved surface 1120, pressure is then applied to the portion of the second adhesive 102 corresponding to the second curved surface 1130. The switching of the two pressure applications can be achieved by moving the position of the second pressing mechanism 14 or by swapping the positions of the first curved surface 1120 and the second curved surface 1130.

[0124] The extension direction of the first rotating shaft is parallel to the third direction Y. Before each rotation of the first carrier 11 , the first carrier 11 can be driven downward by the first roller 131 to return the first carrier 11 and its connecting structure to the standby position.

[0125] In addition, after each rotation of the first carrier 11, the middle portion of the first curved surface 1120 or the second curved surface 1130 can face downward, so that the moving range of the second roller 141 in the second direction Z can be relatively reduced, that is, the stroke of the second roller 141 in the vertical direction can be reduced.
