Description

Technical Field

[0001] This utility model relates to the field of curved screen processing technology, specifically to a curved surface bonding device. Background Technology

[0002] With the development of display technology, the drawbacks of mainstream flat panel displays are becoming increasingly apparent: poor display quality at both ends and easy eye fatigue. In this context, curved displays have emerged. A curved display is a display with a curved display panel, which has the advantages of comfortable viewing, no loss of image quality at both ends, and a strong sense of three-dimensionality.

[0003] In the processing of displays, bonding of different materials is often involved, such as bonding display panels and cover glass. Currently, mainstream bonding technologies and equipment fall into two main categories: one is for flat products, as curved products, due to their curvature, cannot be bonded using traditional flat full-lamination methods; the other, while designed for curved products, often has a fixed curvature and size for the support platform. When bonding curved materials with different curvatures and sizes, the support platform usually needs to be removed and replaced with one that matches the shape of the new curved material. This not only affects bonding efficiency but also increases costs. Therefore, a new curved surface bonding device is needed, whose support platform can be adapted to curved materials with different curvatures and sizes. This invention addresses this technical problem. Utility Model Content

[0004] This invention provides a curved surface bonding device, whose support mechanism is applicable to curved materials with different curvatures and sizes. Therefore, when bonding curved materials with different curvatures and sizes, there is no need to change the support mechanism, thus improving the efficiency of the bonding work.

[0005] A curved surface bonding device includes a support frame, a feeding mechanism connected to the upper part of the support frame, a bearing frame connected to the lower part of the support frame, a plurality of bearing mechanisms connected to the bearing frame, a lifting support mechanism connected to the bearing mechanisms, a moving mechanism connected to the bearing mechanisms, and a measuring mechanism connected to the moving mechanism. The lifting support mechanism is used to carry curved surface material one, the feeding mechanism is used to bond curved surface material two onto curved surface material one, and the measuring mechanism is used to detect the shape of curved surface material one. The measuring mechanism and the lifting support mechanism are electrically connected to a controller.

[0006] Furthermore, the bearing mechanism adopts a bearing block that is slidably connected within the bearing frame, the top of the bearing block is connected to the lifting support mechanism, and the side of the bearing block is connected to the moving mechanism.

[0007] Furthermore, the lifting support mechanism includes a lifting rod with its bottom end connected to the bearing block, a fixed frame fixedly connected to the top end of the lifting rod, and a roller shaft connected to the fixed frame. The roller shaft is used to support the curved material. The lifting rod is electrically connected to the controller.

[0008] Furthermore, the moving mechanism includes a connecting plate connected to the side of the support block, a drive motor connected to the connecting plate, a vertical plate connected to the bottom of the support block, and a roller rotatably connected to the side of the vertical plate. The vertical plate has a through hole, and a connecting shaft is rotatably connected in the through hole. One end of the connecting shaft is coaxially connected to the roller, and the other end of the connecting shaft is connected to the drive motor. The connecting plate is connected to the measuring mechanism.

[0009] Furthermore, the measuring mechanism includes a bending rod connected to the connecting plate, a protective shell connected to the bending rod, and a distance sensor connected to the protective shell. The distance sensor is electrically connected to the controller and is located above the roller.

[0010] Furthermore, a connecting frame is connected to the support frame, the bottom of the protective shell abuts against the connecting frame, a strip groove is provided on the top of the connecting frame, and a second roller is connected to the bottom of the protective shell, with the second roller connected in the strip groove.

[0011] Furthermore, the feeding mechanism includes a telescopic component connected to the support frame and an electrostatic chuck connected to the telescopic component. The electrostatic chuck is used to adsorb and place the curved material one and the curved material two.

[0012] The technical effects of this utility model are as follows: (1) In this scheme, several lifting support mechanisms are used to support the curved material 1. The lifting support mechanism can be adjusted according to the curvature of the curved material 1. Through the lifting method, different lifting support mechanisms can contact the curved material 1, thereby achieving the support of the curved material 1. Furthermore, under the drive of the moving mechanism, the lifting support mechanism can be moved. For curved materials 1 of different sizes, the distance between two adjacent lifting support mechanisms can be adjusted in this way, thereby achieving the adaptation to curved materials 1 of different curvatures and sizes. (2) The electrostatic chuck in the pressing mechanism of this scheme can adsorb the curved material one and place it on the lifting support mechanism. Then, the curved material two is placed on the curved material one in the same way to achieve the adhesion between the two. (3) The distance sensor in this scheme can measure the distance between itself and the curved material 1, and adjust the lifting rod to rise accordingly. When the curved material 1 needs to be placed, all lifting rods are started at the same time to rise. The electrostatic chuck will attract the curved material 1 and drive it to fall. When a part of the curved material 1 blocks one of the distance sensors, the corresponding distance sensor will detect the distance between itself and the curved material 1 and send the signal to the controller. The controller will control the corresponding lifting rod to stop rising. In this way, the roller on each lifting rod can contact the curved material 1, thus making it suitable for bearing curved materials 1 with different curvatures. Attached Figure Description

[0018] The technical solution of this utility model will now be clearly and completely described in conjunction with specific embodiments and accompanying drawings.

[0019] See Figures 1-4 A curved surface bonding device includes a support frame 4, a feeding mechanism connected to the upper part of the support frame 4, a bearing frame 5 connected to the lower part of the support frame 4, a plurality of bearing mechanisms connected to the bearing frame 5, a lifting support mechanism connected to the bearing mechanisms, a moving mechanism connected to the bearing mechanisms, and a measuring mechanism connected to the moving mechanism. The lifting support mechanism is used to carry curved surface material one, the feeding mechanism is used to bond curved surface material two onto curved surface material one, and the measuring mechanism is used to detect the shape of curved surface material one. The measuring mechanism and the lifting support mechanism are electrically connected to a controller. The controller can be connected to any position without affecting operation, which will not be described in detail here.

[0020] Furthermore, the supporting mechanism adopts a supporting block 2 that is slidably connected within the supporting frame 5. The top of the supporting block 2 is connected to the lifting support mechanism, and the side of the supporting block 2 is connected to the moving mechanism. In this embodiment, the supporting block 2 is convex.

[0021] Furthermore, the lifting support mechanism includes a lifting rod 6 connected to the bottom end of the bearing block 2, a fixed frame 7 fixedly connected to the top end of the lifting rod 6, and a roller 8 connected to the fixed frame 7. The roller 8 is used to support the curved material. The lifting rod 6 is electrically connected to the controller. In this solution, the lifting rod 6 can be an electric push rod or other device that can achieve lifting; its type is not limited here.

[0022] Furthermore, the moving mechanism includes a connecting plate 15 connected to the side of the support block 2, a drive motor 16 connected to the connecting plate 15, a vertical plate 3 connected to the bottom of the support block 2, and a roller 1 rotatably connected to the side of the vertical plate 3. The vertical plate 3 has a through hole, and a connecting shaft 18 is rotatably connected within the through hole. One end of the connecting shaft 18 is coaxially connected to the roller 1, and the other end of the connecting shaft 18 is connected to the drive motor 16. The connecting plate 15 is connected to the measuring mechanism. In this embodiment, the connecting plate 15 has a hole to facilitate the connection between the connecting shaft 18 and the drive motor 16. The drive motor 16 can be fixed to the connecting plate 15 by a motor bracket, which will not be described in detail here. In this embodiment, the vertical plates 3 are arranged in pairs, with one end of the roller 1 rotatably connected to one of the vertical plates 3, and the other end coaxially connected to the connecting shaft 18.

[0023] Furthermore, the measuring mechanism includes a bent rod 17 connected to the connecting plate 15, a protective shell 11 connected to the bent rod 17, and a distance sensor 10 connected to the protective shell 11. The distance sensor 10 is electrically connected to the controller and is located above the roller 8. In this embodiment, the bent rod 17 is L-shaped. Multiple controllers can be provided in this embodiment, each controller being electrically connected to a distance sensor 10 and a lifting rod 6. The connection method, corresponding circuit structure, and control principle are all common knowledge in the art and will not be detailed here. The circuit structure connected to the distance sensor 10 can be housed inside the protective shell 11. In this embodiment, a distance threshold can be set. For example, when the distance measured by the distance sensor 10 is less than or equal to the threshold, it is considered that the curved material has blocked the front of the distance sensor 10.

[0024] Furthermore, a connecting frame 9 is connected to the support frame 4, and the bottom of the protective shell 11 abuts against the connecting frame 9. A strip groove 14 is formed on the top of the connecting frame 9, and a second roller 19 is connected to the bottom of the protective shell 11, with the roller 19 positioned within the strip groove 14. This design enhances the stability of the protective shell 11 during movement. The roller 19 is configured as follows... Figure 4As shown, the rotating shaft connected to roller 19 is connected inside the protective shell 11, and the bottom of roller 19 protrudes from inside the protective shell 11. This is an arrangement that is easy for those skilled in the art to conceive of, and will not be described in detail here.

[0025] Furthermore, the feeding mechanism includes a telescopic member 13 connected to the support frame 4 and an electrostatic chuck 12 connected to the telescopic member 13. The electrostatic chuck 12 is used to adsorb and place curved material one and curved material two. The telescopic member 13 can specifically be a hydraulic cylinder or an electric cylinder, etc. In this solution, the bottom shape of the electrostatic chuck 12 is the same as the shape of curved material one and curved material two. When it is necessary to replace the curved material with other curvatures and sizes, it is also necessary to replace the electrostatic chuck 12 with one of the corresponding shapes. In this embodiment, the connection between the top of the electrostatic chuck 12 and the telescopic member 13 is a detachable connection, which is common knowledge in the art. For example, it can be done in the following way: a plate one is fixed to the end of the telescopic member 13, and a plate two is fixed to the top of the electrostatic chuck 12. The plate one and the plate two are connected by bolts. The above method is only one possible way. Those skilled in the art can also achieve a detachable connection in other ways, which will not be described in detail here.

[0026] The working process of this utility model is as follows: First, the spacing between the lifting rods 6 needs to be adjusted according to the length of the curved material. When the length is long, the spacing between the lifting rods 6 needs to be increased. Specifically, the following method is used: Start the drive motor 16, so that the drive motor 16 drives the roller 1 to rotate on the ground through the connecting shaft 18. The vertical plate 3 connected to the roller 1 will drive the bearing block 2 to move within the bearing frame 5, thereby changing the spacing between two adjacent lifting rods 6. At this time, the bent rod 17 connected to the connecting plate 15 will also move, thereby driving the protective shell 11 to move, so that the distance sensor 10 on the protective shell 11 is always located directly above the lifting rod 6. Then, the curved material 1 is adsorbed by the electrostatic chuck 12, and the telescopic component 13 is activated, so that the electrostatic chuck 12 will drive the curved material 1 to move downward. At this time, all the lifting rods 6 are activated (all the lifting rods 6 are initially retracted and the tops are at the same height), so that the lifting rods 6 move upward. When a part of the curved material is blocked in front of one of the distance sensors 10, the distance sensor 10 will transmit a signal to the controller. Since the measured distance will be less than or equal to the set threshold, the controller will control the corresponding lifting rod 6 (i.e. the lifting rod 6 directly below the distance sensor 10), so that the corresponding lifting rod 6 stops working. At this time, the corresponding lifting rod 6 no longer rises, while the other lifting rods 6 continue to rise. Finally, through the above method, the final height of the lifting rod 6 will match the curvature of the curved material. When the curved material 1 contacts the roller 8, the telescopic component 13 needs to be stopped and the electrostatic chuck 12's adsorption of the curved material 1 needs to be canceled. At this time, each roller 8 will contact the curved material 1, thereby realizing the bearing of the curved material 1. Then, the second curved material is adsorbed by the electrostatic chuck 12, and under the action of the telescopic component 13, the second curved material moves downward to fit with the first curved material, thereby achieving the bonding between the two curved materials.

[0027] For bonding of curved materials with different curvatures and sizes, traditional methods usually require replacing the support platform and the pressure platform. However, this method only requires replacing the pressure part, i.e., the electrostatic chuck 12, without replacing the support part, thereby improving the efficiency of the bonding work and saving corresponding costs.

[0028] The technical features not described in detail in this solution are based on the conventional operation and general understanding of those skilled in the art and are derived from existing technologies, and will not be elaborated further here.

[0029] The above embodiments are merely preferred embodiments of this utility model. Those skilled in the art can obtain other embodiments from the above embodiments without creative effort. Therefore, the scope of protection of this application is not limited to the above embodiments, but extends to the scope consistent with the principles and features of this solution.
