[0042] In one aspect, referring to Figure 1 , Figure 1 The overall structure of the curved surface bonding device of the present application is shown. An embodiment of the present application provides a curved surface bonding device for bonding the convex surface of one curved glass to the concave surface of another curved glass. Specifically, the curved surface bonding device comprises a workbench 1, a first upper cavity mechanism 2, a lower cavity mechanism 3 and a photographing and scanning mechanism 4 arranged on the workbench 1, and a control unit (not shown) electrically connected with the photographing and scanning mechanism 4.

[0043] For example, referring to Figures 7-9 , the first upper cavity mechanism 2 comprises a first concave jig 21, wherein the first concave jig 21 is used to fix a first material. For example, referring to Figure 2 and Figure 3 , the lower cavity mechanism 3 comprises a first positioning assembly 31, which comprises a positioning platform 311 that is positionally adjustable relative to the first concave jig 21, and a first convex jig 312 arranged on the positioning platform 311, wherein the first convex jig 312 is used to fix a second material. Further, the first concave jig 21 is configured to be movable towards the first convex jig 312 when arranged opposite to the first convex jig 312, so as to press and bond the first material to the second material.

[0044] Wherein the first material and the second material are both 3D curved glass, and the specific structure, shape and function of the first material and the second material are not limited in the present application, as long as they can meet the application requirements. For example, the first material can be a cover curved glass, and the second material can be a functional curved glass. The specific shape and structure of the first concave jig 21 and the first convex jig 312 are also not limited in the present application, as long as they can be adapted to the shape of the first material and the second material, and can fix the first material and the second material. For example, the surface of the first concave jig 21 and the first convex jig 312 can be provided with a plurality of adsorption holes, and the first material is adsorbed and fixed on the first concave jig 21 through the adsorption holes, and the second material is adsorbed and fixed on the first convex jig 312 through the adsorption holes.

[0045] For example, referring to Figures 7-9The first upper cavity mechanism 2 can include a first upper cavity support 22 arranged on the workbench 1, and a first lamination air cylinder 23 penetrating through the top of the first upper cavity support 22, and the first concave jig 21 is arranged at one end of the first lamination air cylinder 23 facing the workbench 1, and the first lamination air cylinder 23 is used to drive the first concave jig 21 to move towards the first convex jig 312, so that the first material fixed on the first concave jig 21 is pressed and bonded to the second material fixed on the first convex jig 312. Wherein, a first pressure sensor 24 is further arranged between the first lamination air cylinder 23 and the first concave jig 21, which is used to obtain the extrusion force of the first lamination air cylinder 23 on the first concave jig 21, and transmit information to the control unit, so as to control the bonding force of the first material and the second material. The periphery of the first pressure sensor 24 can also be provided with a limiting piece for limiting the position of the first pressure sensor 24 in the horizontal direction, so that the force of the first lamination air cylinder 23 always acts vertically on the first pressure sensor 24, to ensure the accuracy of the first pressure sensor 24. For example, the limiting piece can be a guide rail fixed around the first pressure sensor 24.

[0046] For example, referring to Figure 2 and Figure 7 The first upper cavity mechanism 2 further includes a first upper cavity 25, and the first concave jig 21 is accommodated in the first upper cavity 25. Correspondingly, the lower cavity mechanism 3 can also include a lower cavity 32, and the first alignment assembly 31 is accommodated in the lower cavity 32, and the first alignment assembly 31 includes an alignment platform 311 and a first convex jig 312 arranged on the alignment platform 311. Wherein, the first concave jig 21 is used to fix one side of the first material facing the first convex jig 312, and the first convex jig 312 is used to fix one side of the second material facing the first concave jig 21. When the first concave jig 21 is driven by the first lamination air cylinder 23 to move towards the first convex jig 312, the first upper cavity 25 and the lower cavity 32 form a sealed space, and by vacuumizing the sealed space, the first material and the second material are laminated in a vacuum environment, which further improves the lamination precision and eliminates the air bubbles between the first material and the second material.

[0047] Further, referring to Figure 1 The above-mentioned photographing and scanning mechanism 4 includes a scanning assembly 41 and a photographing assembly 42, the scanning assembly 41 is used to obtain the curved profile information of the first material on the first concave jig 21 and the second material on the first convex jig 312, and the photographing assembly 42 is used to obtain the planar image information of the first material on the first concave jig 21 and the second material on the first convex jig 312.

[0048] The control unit is configured to adjust the relative position of the alignment platform 311 and the first concave jig 21 according to the curved surface profile information obtained by the scanning assembly 41 and the planar image information obtained by the photographing assembly 42, so that the convex surface of the first material and the concave surface of the second material are kept in a curved surface alignment state.

[0049] The curved surface fitting device of the present scheme fixes the first material and the second material on the first concave jig 21 and the first convex jig 312 respectively, wherein the first convex jig 312 is arranged on the alignment platform 311. When the first material and the second material are fitted, the photographing assembly 42 and the scanning assembly 41 obtain the planar image information and the curved surface profile information of the first material on the first concave jig, and the planar image and the curved surface profile information of the second material on the first convex jig, and transmit the information to the control unit; the control unit preliminarily adjusts the lower cavity mechanism 3 according to the planar image information of the first material and the second material, so that the first material and the second material are in a planar alignment state; at this time, the control unit adjusts the alignment platform 311 again according to the curved surface profile information of the first material and the second material, so that the first material and the second material are in a curved surface alignment state. At this time, the first material and the second material are in a completely opposite state, the first concave jig moves towards the first convex jig, and the first material is pressed and pasted on the second material. In this way, the curved surface of the first material and the curved surface of the second material are accurately aligned, thereby improving the fitting precision and fitting effect of the first material and the second material, making the two glasses fit more firmly, and the yield higher.

[0050] Further, in order to accurately control the alignment state of the first material and the second material, the control unit is specifically configured to calculate the alignment compensation amount of the first material and the second material according to the curved surface profile information obtained by the scanning assembly 41 and the planar image information obtained by the photographing assembly 42, and adjust the relative position of the alignment platform 311 and the first concave jig 21 according to the alignment compensation amount.

[0051] For example, when the lower cavity mechanism 3 is preliminarily adjusted, the control unit can obtain a plurality of first positioning points according to the planar image information of the first material, and a plurality of second positioning points corresponding one by one to the first positioning points according to the planar image information of the second material, calculate the preliminary alignment compensation amount of the first material and the second material by calculating the positional relationship between the first positioning points and the second positioning points, and preliminarily adjust the alignment platform 311 according to the preliminary alignment compensation amount, so that the first material and the second material are in a planar alignment state.

[0052] Further, the control unit obtains a plurality of third positioning points according to the curved surface profile information of the first material, and a plurality of fourth positioning points corresponding to the third positioning points according to the curved surface profile information of the second material, calculates a re-alignment compensation amount of the third positioning points and the fourth positioning points, and finely adjusts the alignment platform 311 according to the re-alignment compensation amount, so that the first material and the second material are in a completely opposite curved surface alignment state.

[0053] In order to clearly describe the positional relationship of each structural feature and structural feature, the X-axis direction, Y-axis direction and Z-axis direction are used to define the positional relationship of each structure of the curved surface lamination equipment. Among them, the X-axis direction is the width direction of the curved surface lamination equipment, the Y-axis direction is the length direction of the curved surface lamination equipment, and the Z-axis direction is the height direction of the curved surface lamination equipment. The X-axis direction, Y-axis direction and Z-axis direction are perpendicular to each other, and the Z-axis is perpendicular to the workbench 1.

[0054] For example, referring to Figure 3 The alignment platform 311 can be a six-degree-of-freedom alignment platform. The control unit calculates a six-degree-of-freedom compensation amount according to the measurement data of the plurality of first positioning points and the second positioning points or the third positioning points and the fourth positioning points. The six degrees of freedom are the movement degrees of freedom along the X-axis direction, Y-axis direction and Z-axis direction and the rotation degrees of freedom around the three directions. The control unit controls the six-degree-of-freedom alignment platform 311 to move according to the calculated six-degree-of-freedom compensation amount, so as to realize accurate alignment of the first material and the second material.

[0055] For example, the above-mentioned six-degree-of-freedom alignment platform includes an alignment platform plate and an alignment base, and the alignment platform plate and the alignment base are connected through a hinge base. Two X-axis direction driving assemblies and one Y-axis direction driving assembly are arranged on the alignment base, and the X-axis direction driving assembly and the Y-axis direction driving assembly are configured to drive the alignment platform plate to move along the X-axis direction and the Y-axis direction and rotate around the Z-axis direction. Four Z-axis direction driving assemblies are arranged on the alignment base, and the Z-axis direction driving assemblies are configured to drive the alignment platform plate to move along the Z-axis direction and rotate along the X-axis direction and the Y-axis direction. The specific structure and arrangement mode of the above-mentioned X-axis direction driving assembly, Y-axis direction driving assembly and Z-axis direction driving assembly are not limited in the present application, as long as the adjustment of the alignment platform plate can be realized. For example, the driving assembly can be a servo electric cylinder.

[0056] Further, in order to facilitate scanning of the first material and the second material, referring to Figure 4The scanning assembly 41 comprises a first support frame 411, a second support frame 412, a Y-direction scanning linear module 413, an X-direction scanning linear module 414, a Z-direction scanning linear module 415, a rotary driving member 416 and a point spectrum scanner 417. The first support frame 411 is mounted on the workbench 1. The Y-direction scanning linear module 413 is mounted on the first support frame 411. The second support frame 412 is mounted on the Y-direction scanning linear module 413, and the Y-direction scanning linear module 413 is configured to drive the second support frame 412 to move linearly along the Y-axis direction relative to the first support frame 411. The X-direction scanning linear module 414 is arranged on the second support frame 412 and connected with the Z-direction scanning linear module 415. The X-direction scanning linear module 414 is configured to drive the Z-direction scanning linear module 415 to move linearly along the X-axis direction relative to the second support frame 412. The Z-direction scanning linear module 415 is connected with the rotary driving member 416 and configured to drive the rotary driving member 416 to move linearly along the Z-axis direction relative to the X-direction scanning linear module 414. The rotary driving member 416 is connected with the point spectrum scanner 417 and configured to drive the point spectrum scanner 417 to rotate relative to the Z-direction scanning linear module 415.

[0057] For example, referring to Figure 4 In the X-axis direction, the first support frame 411 can be provided in two, respectively mounted on the opposite sides of the workbench 1, and each of the top of the first support frame 411 is provided with a Y-direction scanning linear module 413. The left and right ends of the second support frame 412 are respectively connected to the upper parts of the two Y-direction scanning linear modules 413, and the Y-direction scanning linear modules 413 can drive the second support frame 412 to move linearly along the Y-axis direction. The X-direction scanning linear module 414 is mounted on the top of the second support frame 412 and connected with the Z-direction scanning linear module 415, and the X-direction scanning linear module 414 can drive the Z-direction scanning linear module 415 to move linearly along the X-axis direction. Further, the side of the Z-direction scanning linear module 415 away from the X-direction scanning linear module 414 is connected with the rotary driving member 416, and the Z-direction scanning linear module 415 can drive the X-direction scanning linear module 414 to move linearly along the Z-axis direction. Further, the side of the rotary driving member 416 away from the Z-direction scanning linear module 415 is connected with the point spectrum scanner 417, and the rotary driving member 416 can drive the point spectrum scanner 417 to rotate relative to the Z-direction scanning linear module 415. The X-direction scanning linear module 414, the Y-direction scanning linear module 413, the Z-direction scanning linear module 415 and the rotary driving member 416 are respectively electrically connected with the control unit, and the control unit is used to control the X-direction scanning linear module 414, the Y-direction scanning linear module 413, the Z-direction scanning linear module 415 and the rotary driving member 416 to move according to the positions of the first material and the second material, so that the point spectrum scanner 417 scans the first material and the second material.

The Y-direction alignment linear module 332 can be a linear motor module or a servo electric cylinder.

[0066] Further, in order to improve the automation degree of the curved surface bonding device, the first upper cavity mechanism 2 and the lower cavity mechanism 3 are arranged oppositely, and the photographing and scanning mechanism 4 is arranged adjacent to the first upper cavity mechanism 2. The lower cavity mechanism 3 further includes a moving assembly 33 connected between the workbench 1 and the first alignment assembly 31, and the moving assembly 33 is configured to drive the alignment platform 311 of the first alignment assembly 31 to move linearly along the Y-axis direction to approach or move away from the first upper cavity mechanism 2. Figure 6 ​The lower cavity device further comprises a second alignment assembly 34 installed on the alignment platform 311 of the first alignment assembly 31, and the second alignment assembly 34 comprises a second convex jig 341 for loading the first material; the second alignment assembly 34 is configured to be movable to below the first concave jig 21 of the first upper cavity mechanism 2 under the driving of the alignment platform 311, and to load the first material loaded on the second convex jig 341 to the first concave jig 21.

[0067] In application, the first material is placed on the second convex jig 341 of the second alignment assembly 34, and the alignment platform 311 drives the second convex jig 341 to move along the Y-axis direction to approach the first upper cavity mechanism 2. When the first material is below the first concave jig 21, the second convex jig 341 loads the first material to the first concave jig 21 of the first upper cavity mechanism 2, further improving the automation degree of the curved surface fitting device, facilitating the fixation of the first material on the first concave jig 21, and saving manpower.

[0068] For example, referring to Figure 6 The second alignment assembly 34 comprises the second convex jig 341 arranged on the top and the connecting bracket 342 arranged on the bottom, and the first driving assembly 343 is arranged between the second convex jig 341 and the connecting bracket 342. The connecting bracket 342 is used to install the second alignment assembly 34 on the alignment platform 311, and the first driving assembly 343 is used to drive the second convex jig 341 to move along the Z-axis direction to approach or move away from the first concave jig 21, so as to load the first material on the second convex jig 341 to the first concave jig 21. For example, a plurality of suction holes can also be arranged on the second convex jig 341 for suction fixation of the first material; the first driving assembly 343 can be a pneumatic cylinder or a servo motor cylinder.

[0069] Further, in order to accurately load the first material to the first concave jig 21, the scanning assembly 41 and the photographing assembly 42 are respectively used to obtain the curved surface profile information and the planar image information of the first material on the second convex jig 341; and the control unit is specifically used to adjust the relative position between the alignment platform 311 and the first concave jig 21 according to the curved surface profile information and the planar image information of the first material on the second convex jig 341, so that the first concave jig 21 and the second convex jig 341 maintain the curved surface alignment state.

[0070] At this time, the first material on the second convex jig 341 is in a fully opposite state with the first concave jig 21, the second convex jig 341 drives the first material to move towards the first concave jig 21, and the first material is fed to the first concave jig 21, and the first concave jig 21 adsorbs and fixes the first material on the first concave jig 21 through the adsorption hole. In this way, the first material is accurately fed to the first concave jig 21, ensuring the stability of the first material on the first concave jig 21, and facilitating the subsequent adjustment of the curved surface alignment of the first material and the second material.

[0071] In order to further realize the stable bonding between the first material and the second material, a glue film 8 is also pasted on the side of the second material facing the first material. The specific material of the glue film 8 is not limited in the application, as long as it can realize the bonding between the first material and the second material, and does not affect the use function of the first material and the second material. For example, the glue film 8 can be OCA glue (optical glue), or TBF glue (hot melt adhesive film).

[0072] For example, referring to Figures 11-14 , the curved surface bonding device further comprises a second upper cavity mechanism 5 arranged on the workbench 1, and the second upper cavity mechanism 5 comprises a second concave jig 51; the second concave jig 51 is configured to move towards the first convex jig 312 when arranged opposite to the first convex jig 312, and press and bond the glue film 8 to the second material.

[0073] For example, along the Y-axis direction, the second upper cavity mechanism 5 is located on one side of the first upper cavity mechanism 2, and the second upper cavity mechanism 5 can comprise a second upper cavity support 52, the second upper cavity support 52 is arranged on the workbench 1, and a second bonding air cylinder 53 is arranged on the top of the second upper cavity support 52, the second concave jig 51 is arranged on one end of the second bonding air cylinder 53 facing the workbench 1, and the second bonding air cylinder 53 is used to drive the second concave jig 51 to move towards the first convex jig 312, so that the glue film 8 is pressed and bonded to the second material fixed on the first convex jig 312. The second pressure sensor 54 is arranged between the second bonding air cylinder 53 and the second concave jig 51, which is used to obtain the extrusion force of the second bonding air cylinder 53 on the second concave jig 51, and transmit the information to the control unit, so as to control the bonding force of the glue film 8 and the second material. The second pressure sensor 54 can also be provided with guide rails around it, which are used to limit the position of the second pressure sensor 54 in the horizontal direction, so that the force of the second bonding air cylinder 53 always acts vertically on the second pressure sensor 54, to ensure the accuracy of the detection of the second pressure sensor 54.

[0074] For example, referring to Figure 1 , Figure 2 and Figure 11The second upper cavity mechanism 5 further comprises a second upper cavity 55, and the second concave mold 51 is accommodated in the second upper cavity 55. When the second concave mold 51 is driven by the second laminating cylinder 53 to move towards the first convex mold 312, the second upper cavity 55 and the lower cavity 32 form a sealed space, and the film 8 and the second material are laminated in a vacuum environment by vacuumizing the sealed space, so that air bubbles are avoided between the film 8 and the second material.

[0075] Further, referring to Figure 10 The lower cavity mechanism 3 further comprises a clamping assembly 35 arranged on the alignment platform 311 and above the first convex mold 312, and used for clamping and fixing the film 8 above the second material to facilitate laminating the film 8 and the second material. For example, the clamping assembly 35 comprises a first clamping assembly 351 in the X direction, a second clamping assembly 352 in the Y direction, and a third clamping assembly 353 in the Z direction, wherein the first clamping assembly 351 is used for clamping the film 8 in the X axis direction, the second clamping assembly 352 is used for clamping the film 8 in the Y axis direction, and the third clamping assembly 353 is used for providing the first clamping assembly 351 and the second clamping assembly 352 with a clamping force in the Z axis direction.

[0076] Further, referring to Figure 5 The upper side of the third support frame 421 is further provided with a preheating assembly 426 for preheating the film 8 to soften the film 8. For example, the preheating assembly 426 is connected to one side of the first camera 424, and the preheating assembly 426 comprises an infrared heating pipe and a temperature detection sensor. The infrared heating pipe is used for heating the film 8 by irradiating infrared rays, and the temperature detection sensor is used for detecting the irradiation temperature of the preheating assembly 426 and transmitting the temperature information to the control unit, so that the control unit controls the heating temperature of the film 8 by the preheating assembly 426 according to the obtained temperature information.

[0077] When the film 8 is placed above the second material by the clamping assembly 35, the alignment platform 311 drives the second material and the film 8 to move below the third support frame 421, and the preheating assembly 426 heats the film 8, and then the alignment platform 311 continues to drive the second material and the film 8 to move below the second upper cavity mechanism 5. At this time, the second concave mold 51 is driven by the second laminating cylinder 53 to move towards the film 8 and the second material in the Z axis direction, wherein the second concave mold 51 first contacts the film 8, and then the film 8 and the second material are pressed and adhered between the first convex mold 312 and the second concave mold 51 by the second laminating cylinder 53.

[0078] Further, in order to ensure that the film 8 is laminated flat on the second material without wrinkles, for example, referring to Figure 13 and Figure 14The second concave jig 51 is formed with a receiving cavity 511, and the receiving cavity 511 is provided with an air filling member 512, and the air filling member 512 is provided with a profiled concave module 513; when the first convex jig 312 and the second concave jig 51 are folded, the air filling member 512 is in a full state, and is used to make the film 8 adhere to the first material from the middle part.

[0079] When the second concave jig 51 starts to contact the film 8, the air filling member 512 fills the entire receiving cavity 511, and protrudes from the receiving cavity 511 on the side facing the film 8, so that the air filling member 512 contacts the film 8 from the middle part. With the gradual approach of the second concave jig 51 and the first convex jig 312, the film 8 and the second material also contact from the middle part under the action of the air filling member 512. In the process of abutting and adhering of the film 8 and the second material, the air filling member 512 gradually deflates, and the profiled concave module 513 provided in the air filling member 512 has a curved surface shape matched with the first material, and under the action of the profiled concave module 513, the film 8 is completely adhered to the second material, and a curved surface shape matched with the first material is formed. The second concave jig 51 of the present application contacts the film 8 from the middle part and gradually extends to the edge, avoiding wrinkles around the film 8, and further affecting the adhesion effect.

[0080] For example, referring to Figure 13 and Figure 14 , the second concave jig 51 can include a bottom plate 514 and a side wall 515, the bottom plate 514 is connected with one side of the side wall 515, and together defines the above-mentioned receiving cavity 511. For example, the side wall 515 includes a first side and a second side opposite to the first side, the bottom plate 514 is connected with the first side of the side wall 515, and the receiving cavity 511 is formed between the first side and the second side.

[0081] Further, the second concave jig 51 can further include a first pressing plate 516 and a second pressing plate 517, wherein the first pressing plate 516 is arranged on the side of the side wall 515 away from the bottom plate 516, and the second pressing plate 517 is arranged on the side of the bottom plate 514 close to the side wall 515, one end of the air filling member 512 is clamped and fixed between the first pressing plate 516 and the side wall 515, and the other end is clamped and fixed between the second pressing plate 517 and the bottom plate 516. For example, the first pressing plate 516 and the second pressing plate 517 can be provided with through holes or threaded holes, and the first pressing plate 516 and the side wall 515 or the second pressing plate 517 and the bottom plate 514 can be connected by bolts.

[0082] The profiled concave mold 513 is installed on the side of the second pressing plate 517 away from the bottom plate 514. The profiled concave mold 513 is provided with a plurality of heating blocks 518. When the adhesive film 8 is pasted with the second material, the second upper cavity 55 and the lower cavity 32 form a sealed space. Through vacuum pumping and heating of the heating blocks 518, the adhesive film 8 is fully pasted on the surface of the second material.

[0083] In order to further improve the automation degree of the curved surface pasting device, the curved surface pasting device further comprises an upper and lower feeding mechanism 6 fixedly installed on the workbench 1. Figure 15 The first carrier assembly 66 is installed above the first Y-direction carrying linear module 61, and the first carrier assembly 66 is used for placing the first material and the second material.

The second Y-direction carrying linear module 62 is used for driving the second carrier assembly 67 to move linearly along the Y-axis direction. The Z-direction carrying linear module 64 is installed on one side of the X-direction carrying linear module 63. The carrying mechanism 65 is installed on the side of the Z-direction carrying linear module 64 away from the X-direction carrying linear module 63. Under the driving of the X-direction carrying linear module 63 and the Z-direction carrying linear module 64, the carrying mechanism 65 can move linearly along the X-axis and the Z-axis directions. The carrying mechanism 65 is used for adsorbing the first material, the second material and the adhesive film 8, and carrying them into the lower cavity device.

[0084] Further, referring to Figure 1 , the curved surface pasting device further comprises a vacuum pump 7 for pumping the first upper cavity mechanism 2, the second upper cavity mechanism 5 and the lower cavity mechanism 3 to facilitate adsorption and fixation of the first material, the second material, and to realize full pasting between the first material, the second material and the adhesive film 8.

[0085] On the other hand, referring to Figure 16 , the application also provides a curved surface pasting method, comprising the following steps:
