Abstract

The present application relates to the technical field of curved screen manufacturing, and particularly relates to a fixing jig and a laminating device, which solve the problem of poor adaptability of the fixing jig in the prior art. The fixing jig provided by the present application comprises a first fixing member, a second fixing member and a splicing member. The second fixing member is fixed to the first fixing member. The splicing member is configured to move relative to the first fixing member along a first direction to adjust and maintain the distance between the splicing member and the second fixing member. The side of the second fixing member facing the splicing member has a first jig curved surface. The side of the splicing member facing the second fixing member has a second jig curved surface. When the fixing jig is adapted to the cover plates with the same curved surface shape and different sizes, the first jig curved surface and the second jig curved surface can be adapted to the side edges of the cover plates. Only the relative position of the splicing member on the first fixing member needs to be adjusted to change the distance between the splicing member and the first fixing member, and the fixing jig does not need to be replaced, so that the cost is reduced.

[0030] Preferred embodiments of the present disclosure will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present disclosure and are not intended to limit the scope of protection of the present disclosure.

[0031] It should be noted that in the description of this disclosure, the terms "upper," "lower," "left," "right," "inner," and "outer," which indicate directional or positional relationships, are based on the directional or positional relationships shown in the accompanying drawings. These are used merely for ease of description and do not indicate or imply that the device or element must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this disclosure. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0032] Furthermore, it should be noted that, in the description of this disclosure, unless otherwise expressly specified and limited, the terms "installation," "setup," and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection, an indirect connection through an intermediate medium, or a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this disclosure according to the specific circumstances.

[0033] The curved screen consists of a cover plate and a flexible substrate, which are bonded together under vacuum conditions. Adhesive can be applied to the cover plate or the flexible substrate to enhance the bonding strength between them.

[0034] The cover plate and the flexible substrate are bonded using a bonding device, which includes a fixing fixture and an attachment mechanism. The attachment mechanism is located on one side of the fixing fixture along the second direction. In the example of this invention, the attachment mechanism is located directly below the fixing fixture, which has vent holes that penetrate the first fixing member along the second direction. The surface of the fixing fixture near the attachment mechanism has an inner contour of a cavity that is the same shape as the outer contour of the cover plate. A negative pressure is formed on the side of the fixing fixture away from the attachment mechanism, which allows the cover plate to be adsorbed onto the fixing fixture using the vent holes. The cover plate is a curved cover plate, with a flat top surface and curved sides. Correspondingly, the bottom of the inner contour of the fixing fixture cavity is flat, and the edge portion along the first direction is curved.

[0035] The attachment mechanism includes a contouring fixture and a driving mechanism, which drives the contouring fixture to reciprocate along a first direction. The outer contour shape of the side of the contouring fixture closest to the fixed fixture matches the shape of the inner contour of the cavity of the fixed fixture. The flexible substrate is located between the fixed fixture and the attachment mechanism. As the driving mechanism drives the contouring fixture closer to the fixed fixture, the flexible substrate is pushed closer to the fixed fixture by the contouring fixture. Under the squeezing action of the contouring fixture and the fixed fixture, the cover plate and the flexible substrate are bonded to form a curved screen. After the driving mechanism drives the contouring fixture away from the fixed fixture, it facilitates the demolding of the curved screen. For example, by placing the side of the fixed fixture away from the attachment mechanism in a non-negative pressure state, the curved screen can be detached from the fixed fixture.

[0036] The bonding device includes a fixing fixture and a bonding mechanism located within a vacuum chamber. The bonding mechanism and fixing fixture bond the flexible substrate to the cover plate to form a curved surface, thereby minimizing the possibility of air bubbles forming between the cover plate and the flexible substrate.

[0037] The aforementioned bonding device requires the design and manufacture of corresponding fixing fixtures and contouring fixtures for curved screens of different shapes and sizes. The design and manufacture of molds are costly, and they also increase warehousing costs, as well as the installation and debugging costs for changing fixtures. This is especially true for experimental production lines, where fixture changes are more frequent, resulting in persistently high fixture-related costs in experimental production lines.

[0038] Based on this, embodiments of the present invention provide a fixing fixture, comprising: a first fixing member having a planar fixture bottom surface; a second fixing member fixed to the first fixing member; and a splicing member connected to the first fixing member, the splicing member being configured to move relative to the first fixing member along a first direction to adjust and maintain the spacing between the splicing member and the second fixing member; wherein the second fixing member and the splicing member are disposed opposite to each other along the first direction, the side of the second fixing member facing the splicing member has a first fixture curved surface, the side of the splicing member facing the second fixing member has a second fixture curved surface, the first fixture curved surface and the second fixture curved surface are in contact with the fixture bottom surface, the first fixture curved surface, the second fixture curved surface and the fixture bottom surface located between the first fixture curved surface and the second fixture curved surface constitute the inner contour of the cavity of the fixing fixture.

[0039] The following describes some embodiments of the fixing fixture and the fitting device having the fixing fixture through several specific examples.

[0040] Figure 1 The figure shown is a schematic diagram of the cross-sectional structure of the curved screen provided in an embodiment of the present invention.

[0041] The bonding device is used to bond the cover plate 101 and the flexible substrate 102 in the curved screen 10, wherein the middle of the cover plate 101 is flat and the two sides of the cover plate 101 are curved. Of course, this is only one application of the bonding device provided in this embodiment of the invention. In other possible embodiments, the bonding device can bond two other types of objects to be bonded.

[0042] To facilitate understanding of the embodiments of the present invention, the present invention defines a first direction X, a second direction Y, and a third direction Z in space, wherein any two of the first direction X, the second direction Y, and the third direction Z are perpendicular to each other.

[0043] Figure 6A The diagram shown is a structural diagram of a bonding device in a non-bonding state according to an embodiment of the present invention. Figure 2 The diagram shown is a cross-sectional view of a fixing fixture in the bonding device provided in an embodiment of the present invention.

[0044] like Figure 6A As shown, the bonding device includes a fixing fixture 1 and a bonding mechanism 2, with the bonding mechanism 2 located on one side of the fixing fixture 1 along the second direction Y. In an example of the present invention, the bonding mechanism 2 is located directly below the fixing fixture 1. For example, the fixing fixture 1 and the bonding mechanism 2 are located within a vacuum chamber, and the bonding mechanism 2 and the fixing fixture 1 bond the flexible substrate 102 to the cover plate 101 to form a curved surface, thereby minimizing the possibility of air bubbles forming between the cover plate 101 and the flexible substrate 102.

[0045] like Figure 6A and Figure 2 As shown, the fixing fixture 1 has an inner cavity contour 11 on the side facing the attachment mechanism 2. The shape of the inner cavity contour 11 is the same as the shape of the outer contour of the cover, so that the cover plate 101 can fit into the inner cavity contour 11. Specifically, as... Figure 2 As shown, the fixing fixture 1 includes a first fixing member 12, a second fixing member 13, and a splicing member 14. The second fixing member 13 is fixed to the first fixing member 12, and the splicing member 14 is configured to move relative to the first fixing member 12 along a first direction X to adjust and maintain the distance between the splicing member 14 and the second fixing member 13. The first fixing member 12 has a planar fixture bottom surface 121 on the side facing the attachment mechanism 2. The second fixing member 13 and the splicing member 14 are arranged opposite to each other along the first direction X. The second fixing member 13 has a first fixture curved surface 131 on the side facing the splicing member 14, and the splicing member 14 has a second fixture curved surface 141 on the side facing the second fixing member 13. The first fixture surface 131 and the second fixture surface 141 are close to the bottom surface 121 of the fixture and are tangent to each other to form a smooth transition. The first fixture surface 131, the second fixture surface 141 and the bottom surface 121 of the fixture located between the first fixture surface 131 and the second fixture surface 141 constitute the inner contour 11 of the cavity of the fixing fixture 1.

[0046] When the fixing fixture 1 provided in this embodiment of the invention adapts to cover plates 101 with the same curved surface shape but different sizes, the first fixture curved surface 131 of the first fixing member 12 and the second fixture curved surface 141 of the splicing member 14 can adapt to the side of the cover plate 101. It is only necessary to adjust the relative position of the splicing member 14 on the first fixing member 12 to change the distance between the splicing member 14 and the first fixing member 12, without replacing the fixing fixture 1, thereby reducing the cost of the fixing fixture 1. In addition, when the fixing fixture 1 provided in this embodiment of the invention adapts to cover plates 101 with different curved surface shapes, it is only necessary to replace the first fixing member 12 and the splicing member 14 to change the first fixture curved surface 131 and the second fixture curved surface 141 so that the first fixture curved surface 131 and the second fixture curved surface 141 can adapt to the corresponding cover plate 101. Therefore, only the first fixing member 12 and the splicing member 14 need to be designed and processed, thereby reducing the design and processing cost of the fixing fixture 1.

[0047] For example, the first fixing member 12 has a guide groove 122 extending along the first direction X on the side near the attachment mechanism 2, and the splicing member 14 is provided with a sliding part 142 that slides with the guide groove 122. When the sliding part 142 on the splicing member 14 slides with the guide groove 122, the splicing member 14 fits against the bottom surface 121 of the fixture, thereby ensuring that the curved surface 131 of the first fixture can be connected with the bottom surface 121 of the fixture. For example, the second fixing member 13 is fixed to the end of the first fixing member 12 along the first direction X, which facilitates the connection between the curved surface 141 of the second fixture and the bottom surface 121 of the fixture.

[0048] For example, the splicing component 14 is connected to a locking member 143, which is configured to lock the splicing component 14 and the first fixing member 12 after adjusting the distance between the splicing component 14 and the second fixing member 13. For example, the locking member 143 is a bolt, threadedly connected to the splicing component 14, and as the locking member 143 is screwed deeper, it abuts against the first fixing member 12 to lock the splicing component 14 and the first fixing member 12, keeping the distance between the splicing component 14 and the second fixing member 13 constant. In this case, the movement between the splicing component 14 and the first fixing member 12 can be manually operated by the operator, and then the locking member 143 is used to lock the splicing component 14 and the first fixing member 12 to maintain the distance between the splicing component 14 and the second fixing member 13, thereby reducing the complexity of the structure in the fixing fixture 1.

[0049] Figure 3 The diagram shown is a cross-sectional view of another fixing fixture in the bonding device provided in an embodiment of the present invention. Figure 4 The diagram shown is a schematic diagram of another fixing fixture in the bonding device provided in an embodiment of the present invention along the second direction.

[0050] For example, such as Figure 3 and Figure 4 As shown, a fifth drive mechanism 15 is provided on the side of the first fixing member 12 near the attachment mechanism 2. The fifth drive mechanism 15 is configured to drive the splicing member 14 to reciprocate along the first direction X, thereby changing the distance between the splicing member 14 and the second fixing member 13. For example, the fifth drive mechanism 15 can be any one of a cylinder, a hydraulic cylinder, and a linear module, wherein the linear module can be any one of a synchronous belt type linear module, a lead screw type linear module, and a linear motor module.

[0051] Figure 5A The figure shown is a cross-sectional view of a linear module provided in an embodiment of the present invention.

[0052] For example, such as Figure 5A As shown, the synchronous belt type linear module includes a module housing 201, a slider 203, a synchronous belt 204, a drive roller 205, a driven roller 206, and a drive motor. The module housing 201 is hollow inside. The drive roller 205 and the driven roller 206 are located at opposite ends inside the module housing 201 and are rotatably connected to it. The drive motor 207 is fixed to the outside of the module housing 201, and its output shaft is connected to the drive roller 205 to drive the drive roller 205 to rotate. The synchronous belt 204 is sleeved on the drive roller 205 and the driven roller 206. Synchronous teeth are provided on the inner side of the synchronous belt 204. Synchronous teeth are also provided on the circumferential surfaces of the drive roller 205 and the driven roller 206. The synchronous teeth on the drive roller 205 and the driven roller 206 mesh with the synchronous teeth on the inner side of the synchronous belt 204 to increase the friction between the synchronous belt 204 and the drive roller 205 and the driven roller 206. The module housing 201 has an opening 202 on one side, which extends along the length of the module housing 201. A slider 203 is located within the opening 202 and is slidably connected to the module housing 201. The slider 203 is fixed to a timing belt 204, and a moving part is fixed to the slider 203. When the drive motor 207 rotates, it can drive the timing belt 204 to move, thereby moving the slider 203 and the moving part fixed to the slider 203. The forward and reverse rotation of the drive motor 207 determines the direction of movement of the slider 203 and the moving part. By controlling the forward and reverse rotation of the drive motor 207, the reciprocating movement of the slider 203 and the moving part can be achieved.

[0053] Figure 5B The figure shown is a cross-sectional view of another linear module provided in an embodiment of the present invention.

[0054] For example, such as Figure 5BAs shown, the lead screw type linear module includes a module housing 201, a guide rail 208, a slider 203, a lead screw 209, and a drive motor 207. The module housing 201 is hollow inside, and an opening 202 is provided on one side of the module housing 201, extending along the length direction of the module housing 201. The guide rail 208 is fixed inside the module housing 201 and extends along the length direction of the module housing 201. The lead screw 209 extends along the length direction of the module housing 201, passes through the module housing 201, and is rotatably connected to the module housing 201. The drive motor 207 is fixed to the outside of the module housing 201, and its output shaft is connected to the lead screw 209 to drive the lead screw 209 to rotate. A portion of the slider 203 is located inside the module housing 201, while the other portion extends out of the module housing 201 from the opening 202. The portion of the slider 203 inside the module housing 201 is slidably connected to the guide rail 208 and threadedly connected to the lead screw 209. The portion of the slider 203 outside the module housing 201 is fixedly connected to the moving component. The drive motor 207 can drive the lead screw 209 to rotate. Utilizing the threaded connection between the lead screw 209 and the slider 203, and with the guide rail 208 guiding and restricting the rotation of the slider 203, the rotation of the lead screw 209 can drive the slider 203 to move along the guide rail 208. The forward and reverse rotation of the drive motor 207 determines the direction of movement of the slider 203. By controlling the forward and reverse rotation of the drive motor 207, the reciprocating movement of the slider 203 and the moving component can be achieved. For example, the lead screw 209 can be a ball screw or a conventional lead screw.

[0055] For example, such as Figure 3 As shown, the first fixing member 12 has an air hole 123 extending through it along the second direction Y. An air hole 123 is also provided in the area where the inner contour 11 of the cavity is located. A negative pressure is applied above the first fixing member 12. Under the action of the negative pressure, an adsorption force is generated on the cover plate 101 located at the inner contour 11 of the cavity. The adsorption force exerted on the cover plate 101 by the negative pressure is greater than the weight of the cover plate 101, thereby allowing the cover plate 101 to stably adhere to the inner contour 11 of the cavity.

[0056] For example, such as Figure 3 and Figure 4 As shown, the splicing component 14 is connected to a baffle 144, which is located on the side of the splicing component 14 away from the second fixing member 13 and is in contact with the bottom surface 121 of the fixture. As the splicing component 14 moves along the first direction X, the baffle 144 can close the air holes 123 on the side of the splicing component 14 away from the second fixing member 13, reducing the airflow through the air holes 123 that are not used to adsorb the cover plate 101, thereby increasing the negative pressure adsorption force on the cover plate 101.

[0057] For example, such as Figure 3As shown, the bonding device also includes a first driving mechanism 16, which is configured to drive the first fixing member 12 to rotate along the second direction Y, so as to adjust the position of the splicing member 14 and the first fixing member 12, so that the first fixture curved surface 131 and the second fixture curved surface 141 are aligned with the bonding mechanism 2, thereby improving the bonding quality of the flexible substrate 102 and the cover plate 101. For example, the first driving mechanism 16 is a drive motor and a matching reducer, and the output shaft of the reducer is fixed to the first fixing member 12.

[0058] Figure 6B The diagram shown is a structural diagram of a bonding device in a bonding state according to an embodiment of the present invention.

[0059] In some examples, such as Figure 6A and Figure 6B As shown, the attachment mechanism 2 includes a contour jig 21 and a second drive mechanism 22. The second drive mechanism 22 is configured to drive the contour jig 21 to reciprocate along a second direction Y. The outer contour shape of the contour jig 21 on the side closest to the fixed jig 1 is adapted to the shape of the inner contour 11 of the cavity. That is, after the contour jig 21 moves toward the fixed jig 1, the distance between the outer contour of the contour jig 21 and the inner contour 11 on the normal lines is the same at all points. As the contour jig 21 approaches the fixed jig 1, the contour jig 21 pushes the flexible substrate 102 closer to the fixed jig 1. After the contour jig 21 and the fixed jig 1 are molded together, the flexible substrate 102 and the cover plate 101 are attached to form the curved screen 10. After the contour jig 21 moves away from the fixed jig 1, a demolding space can be formed between the contour jig 21 and the fixed jig 1. At this time, the negative pressure above the first fixed plate is weakened or stopped, and the suction force of the negative pressure on the cover plate 101 is reduced or even disappeared. The curved screen 10 is detached from the fixed jig 1 under the action of gravity.

[0060] For example, the second drive mechanism 22 is one or more sets of synchronously operating cylinders or hydraulic cylinders.

[0061] Figure 7 The diagram shown is a structural diagram of another bonding device provided in an embodiment of the present invention in a non-bonding state.

[0062] In other examples, such as Figure 7As shown, the attachment mechanism 2 includes a first attachment roller 23, a second attachment roller 24, and a third drive mechanism 25. The first attachment roller 23 rotates along a first direction X and is configured to roll into contact with the bottom surface 121 of the fixture located between the first fixture surface 131 and the second fixture surface 141. The second attachment roller 24 includes at least one roller, rotates along a third direction Z, and is configured to roll into contact with the first fixture surface 131 and / or the second fixture surface 141. The third drive mechanism 25 is configured to drive either the first attachment roller 23 or the second attachment roller 24 to move along the first direction X and the second direction Y, so that either the first attachment roller 23 or the second attachment roller 24 rolls into contact with the corresponding area of ​​the cavity contour 11 in the fixing fixture 1.

[0063] It should be noted that both the first attaching roller 23 and the second attaching roller 24 are equipped with mounting brackets, and both the first attaching roller 23 and the second attaching roller 24 are rotatably connected to their respective mounting brackets.

[0064] For example, the third drive mechanism 25 includes a fixed platform 251, a first drive assembly 252, a second drive assembly 253, and a third drive assembly 254. Multiple sets of first drive assemblies 252 are provided, with each first attachment roller 23 and second attachment roller 24 corresponding to one set of first drive assemblies 252. One set of first drive assemblies 252 drives the corresponding first attachment roller 23 to reciprocate along the second direction Y, and another set of first drive assemblies 252 drives the corresponding second attachment roller 24 to reciprocate along the second direction Y. The fixed platform 251 is parallel to the first fixing member 12. Multiple sets of first drive assemblies 252 are fixed to the side of the fixed platform 251 facing the fixing fixture 1. The second drive assembly 253 and the third drive assembly 254 are located on the side of the fixed platform 251 away from the fixing fixture 1. Specifically, the second drive assembly 253 drives the fixed platform 251 to reciprocate along the first direction X, and the third drive assembly 254 drives the fixed platform 251 to reciprocate along the third direction Z.

[0065] For example, the first drive assembly 252, the second drive assembly 253, and the third drive assembly 254 can be any one of a cylinder, a hydraulic cylinder, and a linear module. The linear module can be any one of a synchronous belt type linear module, a lead screw type linear module, and a linear motor module.

[0066] For example, such as Figure 7 As shown, there is one second attaching roller 24. The second attaching roller 24 is driven to move along the first direction X and the second direction Y by the third driving mechanism 25, so that the second attaching roller 24 rolls and engages with the first fixture curved surface 131 and the second fixture curved surface 141 in sequence, so that the flexible substrate 102 and the cover plate 101 are attached to the curved side.

Figure 8B The diagram shown is a structural diagram of the first bonding roller in a bonding state in another bonding device provided by an embodiment of the present invention. Figure 8C The diagram shown is a structural diagram of the second attaching roller in a bonding state in another bonding device provided by an embodiment of the present invention.

[0068] For example, such as Figure 8A , Figure 8B and Figure 8C As shown, two second attaching rollers 24 are provided, located at opposite ends of the first attaching roller 23 along the first direction X. One second attaching roller 24 is close to the first fixture surface 131, and the other is close to the second fixture surface 141. The third drive mechanism 25 moves the second attaching rollers 24 along the first direction X and the second direction Y, enabling either the second attaching roller 24 near the first fixture surface 131 to roll into contact with it, or the second attaching roller 24 near the second fixture surface 141 to roll into contact with it. This reduces the maximum stroke of the third drive mechanism 25 in the first direction X, thereby reducing the equipment cost of the third drive mechanism 25.

[0069] Figure 8D The diagram shows the positional relationship of the first attaching roller, the second attaching roller, and the flexible substrate along the second direction when the bonding device provided in another embodiment of the present invention is in a non-bonding state.

[0070] In addition, combined Figure 8D As shown, since the length of the bottom surface 121 of the fixture 1 located between the first fixture surface 131 and the second fixture surface 141 in the first direction X will change with the size of the cover plate 101, the length of the first attaching roller 23 can be set to be relatively short. During the process of the first attaching roller 23 rolling and attaching along the third direction Z, a portion of the flexible substrate 102 can be attached to the cover plate 101. Then, the position of the first attaching roller 23 is adjusted by the third driving mechanism 25, and the flexible substrate 102 and the cover plate 101 are rolled and attached multiple times to achieve the bonding of the flexible substrate 102 and the cover plate 101 in the middle area.

[0071] like Figure 8DAs shown, the length of the second attaching roller 24 can be set to be relatively long, that is, the length of the second attaching roller 24 is greater than or equal to the dimension of the cover plate 101 in the third direction Z. In this way, the second attaching roller 24 can roll and bond the curved sides of the flexible substrate 102 and the cover plate 101 with a single rolling engagement with the splicing member 14 or the second fixing member 13. For example, the curvature of the second attaching roller 24 is less than the curvature of the first fixture surface 131 and the curvature of the second fixture surface 141, so as to ensure that the second attaching roller 24 makes line contact with the first fixture surface 131 and the second fixture surface 141 during rolling engagement.

[0072] When the first attaching roller 23 and the second attaching roller 24 are in the standby state, the orthographic projection of the first attaching roller 23 on the fixing fixture 1 is outside the orthographic projection range of the flexible substrate 102 and the fixing fixture 1, and the orthographic projection of the second attaching roller 24 on the fixing fixture 1 is also outside the orthographic projection range of the flexible substrate 102 and the fixing fixture 1. In addition, the stroke of the third driving mechanism 25 in the third direction Z exceeds the size of the cover plate 101 in the third direction Z, thereby ensuring that the first attaching roller 23 can completely roll and adhere the middle area of ​​the flexible substrate 102 to the cover plate 101; the stroke of the third driving mechanism 25 in the first direction X exceeds the size of the curved surface 131 of the first fixture or the curved surface 141 of the second fixture in the first direction X, thereby ensuring that the second attaching roller 24 can completely roll and adhere the flexible substrate 102 to the curved side of the cover plate 101.

[0073] It should be noted that the rolling engagement between the first attaching roller 23 and the bottom surface 121 of the fixture, and the rolling engagement between the second attaching roller 24 and the curved surface 131 or 141 of the first fixture, are not actual rolling contacts. Rather, they involve pressing and bonding the flexible substrate 102 and the cover plate 101 between the first attaching roller 23 and the bottom surface 121 of the fixture, and the second attaching roller 24 and the curved surface 131 or 141 of the first fixture, through a rolling engagement. In other embodiments of the present invention, the rolling engagement of the two components also refers to pressing and bonding the flexible substrate 102 and the cover plate 101 between the two components through a rolling compression method.

[0074] Figure 9A The diagram shown is a structural diagram of another bonding device provided in an embodiment of the present invention in a non-bonding state. Figure 9B The diagram shown is a structural diagram of another bonding device provided in an embodiment of the present invention in a bonding state. Figure 9C The diagram shows the positional relationship of two third attaching rollers in a second direction in another bonding device provided by an embodiment of the present invention.

[0075] In some other examples, such as Figure 9A and Figure 9BAs shown, the attachment mechanism 2 includes two third attachment rollers 26 and a fourth drive mechanism 27. The third attachment rollers 26 rotate in the third direction Z and are configured to roll into contact with the inner contour 11 of the cavity of the fixing fixture 1 to roll and attach the flexible substrate 102 to the cover plate 101 to form a curved screen 10. Both third attachment rollers 26 first roll and reciprocate along the first direction X, engaging with the middle region of the cavity contour 11 to roll and attach the flexible substrate 102 located in the middle region of the cavity contour 11 to the cover plate 101. Then, one of the third attachment rollers 26 rolls from the middle region of the cavity contour 11 toward the first fixture surface 131, rolling and attaching the flexible substrate 102 corresponding to the region between the middle region of the cavity contour 11 and the first fixture surface 131 to the cover plate 101. The other third attachment roller 26 rolls from the middle region of the cavity contour 11 toward the second fixture surface 141, rolling and attaching the flexible substrate 102 corresponding to the region between the middle region of the cavity contour 11 and the second fixture surface 141 to the cover plate 101. The fourth drive mechanism 27 is configured to drive the third attachment roller 26 to move at least along the first direction X and the second direction Y, so that the third attachment roller 26 approaches the fixing fixture 1 and rolls with the inner contour 11 of the cavity, or moves the third attachment roller 26 away from the fixing fixture 1 so that the curved screen 10 can be disengaged from the fixing fixture 1.

[0076] It should be noted that the third attachment roller 26 is equipped with a mounting bracket, and the mounting bracket corresponding to the third attachment roller 26 is rotatably connected.

[0077] For example, the length of the third attaching roller 26 in the third direction Z is greater than or equal to the size of the cover plate 101 in the third direction Z. During the rolling engagement of the third attaching roller 26 with the fixing fixture 1, the third attaching roller 26 can completely cover the flexible substrate 102 and the cover plate 101. One rolling press can attach the flexible substrate 102 to the cover plate 101.

[0078] For example, if the length of the third attaching roller 26 in the third direction Z is less than the size of the cover plate 101 in the third direction Z, during the rolling engagement between the third attaching roller 26 and the fixing fixture 1, the third attaching roller 26 cannot completely cover the flexible substrate 102 and the cover plate 101, and multiple rolling presses are required to attach the flexible substrate 102 to the cover plate 101. At this time, the third attaching roller 26 needs to move in the third direction Z to change the rolling position; that is, the fourth drive mechanism 27 also needs to drive the third attaching roller 26 to move along the third direction Z.

[0079] For example, such as Figure 9AAs shown, the fourth drive mechanism 27 includes a fixed platform 271, a fourth drive assembly 272, a fifth drive assembly 273, a sixth drive assembly 274, and a seventh drive assembly 275. The fixed platform 271 is parallel to the first fixing member 12. The fourth drive assembly 272 is fixed to the side of the fixed platform 271 near the fixing fixture 1. The fifth drive assembly 273, the sixth drive assembly 274, and the seventh drive assembly 275 are connected to the side of the fixed platform 271 away from the fixing fixture 1. Wherein, as... Figure 9C As shown, the fourth drive assembly 272 includes four components, which are staggered along the third direction Z. Two of the fourth drive assemblies 272 drive the same third attachment roller 26 to reciprocate along the first direction X, while the other two drive assemblies 272 drive another third attachment roller 26 to reciprocate along the first direction X. It should be noted that the strokes of the two third attachment rollers 26 are different to ensure that the two third attachment rollers 26 do not interfere with each other. Figure 9A As shown, the sixth drive assembly 274 is connected to the moving part (such as a piston rod) of the fifth drive assembly 273, and the fifth drive assembly 273 is used to drive the sixth drive assembly 274 to reciprocate along the second direction Y; the seventh drive assembly 275 is connected to the moving part (such as a slider) of the sixth drive assembly 274, and the sixth drive assembly 274 is used to drive the seventh drive assembly 275 to reciprocate along the third direction Z; the fixed platform 271 is connected to the moving part (such as a slider) of the seventh drive assembly 275, and the seventh drive assembly 275 is used to drive the fixed platform 271 to reciprocate along the first direction X.

[0080] For example, the fourth drive assembly 272, the fifth drive assembly 273, the sixth drive assembly 274, and the seventh drive assembly 275 can be any one of a cylinder, a hydraulic cylinder, and a linear module. The linear module can be any one of a synchronous belt type linear module, a lead screw type linear module, and a linear motor module.

[0081] In some examples, the bonding apparatus further includes a carrier film 3 extending along a first direction X, located between the fixing fixture 1 and the bonding mechanism 2, for carrying the object to be bonded (such as a flexible substrate). The carrier film 3 is similar to a conveyor belt, capable of carrying multiple flexible substrates 102, and capable of conveying the flexible substrates 102 between the fixing fixture 1 and the bonding mechanism 2.

[0082] During the process of attaching the flexible substrate 102 to the cover plate 101 in cooperation with the attachment mechanism 2 and the fixing fixture 1, the carrier film 3 moves together with the flexible substrate 102 to ensure that the flexible substrate 102 can remain flat during the movement and improve the bonding effect.

[0083] The above description is merely a specific embodiment of this disclosure, but the scope of protection of this disclosure is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this disclosure should be included within the scope of protection of this disclosure. Therefore, the scope of protection of this disclosure should be determined by the scope of the claims.
