Description

Technical Field

[0001] This invention relates to the field of display screen processing, and more particularly to an automatic assembly and bonding device for liquid crystal display modules. Background Technology

[0002] Liquid crystal display (LCD) modules are the core components for image display in various electronic devices. Their core function is to accurately convert electrical signals into visible light images. The efficient implementation of this process is gradually breaking through traditional technological limitations through the innovative application of metamaterials. The LCD panel itself does not emit light; it relies on a backlight module to provide a stable and uniform light source for normal display. The integration of metamaterials into the backlight module provides crucial support for upgrading the light source performance. By designing metamaterial optical elements with specific micro- and nano-structures, the light emitted by the backlight module can be precisely controlled. This not only significantly improves light transmission efficiency and reduces light loss but also optimizes light uniformity, resulting in more balanced brightness and more delicate colors in the displayed image, thus improving the display effect from the source of the light source. Meanwhile, the LCD panel and backlight module require specialized assembly and bonding equipment during the assembly process to ensure their structural stability and optical compatibility. Traditional bonding equipment is limited in its adaptability and accuracy when dealing with panels of different specifications. However, the introduction of metamaterials has opened up a new path for optimizing the performance of assembly and bonding equipment: a flexible metamaterial layer can be integrated into the surface of key contact components of the bonding equipment. Utilizing the controllable elastic deformation characteristics and surface adsorption capabilities of metamaterials, the equipment can more tightly and smoothly bond panels and backlight modules of different thicknesses or curved designs. This avoids component damage caused by uneven pressure during bonding and further improves bonding accuracy, ensuring the overall assembly quality and service life of the LCD module.

[0003] However, existing assembly and bonding equipment can only be used to bond flat LCD panels. When bonding curved LCD panels and backlight modules with optical adhesive together, workers often have to manually press them together, which greatly increases the labor intensity of the workers. Summary of the Invention

The first pressure frame is connected to the download frame, and the second pressure frame is connected to the upper loading frame.

[0006] Preferably, the two ends of the central shaft are inlaid with bearing seats, the lower end of the bearing seats is fixed to the housing, and positioning claws are fixedly installed on both sides of the bearing seats, one of the positioning claws resting on the front swing frame.

[0007] Preferably, the lower end of the upper swing frame extends with an upper convex plate, the rear part of the outer surface of the central shaft is rotatably mounted with a lower swing frame, the upper end of the lower swing frame extends with a lower convex plate, the lower end of the upper convex plate is symmetrically fixedly mounted with two guide columns, the lower convex plate is slidably mounted on the outer surface of the guide columns, and the other positioning claw is abutted on the lower swing frame.

[0008] Preferably, a top cap is coaxially embedded at the lower end of the guide post, and a top-closing spring is wound around the outside of the guide post. The upper end of the top-closing spring is fixed to the lower end of the lower convex plate, and the lower end of the top-closing spring is fixed to the upper end of the top cap. The top-closing spring is in a contracted state.

[0009] Preferably, the side of the download rack extends into a first slot, the lower end of the first pressure frame is rotatably mounted inside the first slot, the side of the upper rack extends into a second slot, the lower end of the second pressure frame is rotatably mounted inside the second slot, the opening direction of the second slot is opposite to the opening direction of the first slot, and the second slot is located behind the first slot.

[0010] Preferably, the pushing member includes a rod seat fixedly installed at the rear edge of the inner bottom surface of the housing. A T-shaped slider is slidably installed inside the rod seat. A threaded rod is rotatably installed between the upper and lower end faces of the rod seat. The threaded rod extends through the lower end of the rod seat. The T-shaped slider is screwed onto the outer surface of the threaded rod. A non-circular frame is embedded at the front end of the T-shaped slider. A Z-shaped frame is fixedly installed at the end of the non-circular frame. A second connecting frame extends from one end of the Z-shaped frame. The upper end of the first pressing frame is rotatably connected to the second connecting frame. A first connecting frame extends from the other end of the Z-shaped frame. The upper end of the second pressing frame is rotatably connected to the first connecting frame.

[0011] Preferably, a servo motor is fixedly installed at the lower end of the rod holder, and the output end of the servo motor is fixed to the lower end of the threaded rod.

[0012] Preferably, the lifting component includes a servo cylinder fixedly installed at the center of the inner bottom surface of the housing. A lifting platform is fixedly installed at the telescopic end of the servo cylinder. A guide sleeve is embedded through the corner of the lifting platform. A guide rod is slidably installed inside the guide sleeve. The guide rod extends through the upper and lower ends of the guide sleeve. The lower end of the guide rod is fixed to the housing. Two fixed brackets extend symmetrically from the lower end of the arc-shaped support. The lower ends of the fixed brackets are fixed to the upper end of the lifting platform.

[0013] Compared with the prior art, the present invention has the following beneficial effects: 1. By lowering the No. 1 and No. 2 pressure frames, the download frame and the upper frame can be pushed, which in turn drives the upper and lower pressure rollers to move in opposite directions around the central axis, that is, around the center of the curved LCD panel. The lower pressure roller moves from the middle of the backlight module towards one end of the backlight module to press the backlight module and one side of the curved LCD panel together. The upper pressure roller moves from the middle of the backlight module, which is located after being pressed by the lower pressure roller, towards the other end of the backlight module to press the backlight module and the other side of the curved LCD panel together. In this way, the backlight module and the curved LCD panel are fully pressed together and bonded together. This process does not require manual pressing by workers, effectively reducing the labor intensity of workers.

[0014] 2. When the No. 1 pressure frame moves downward, pushing the lower pressure roller on the lower frame to move in an arc to roll and press along the backlight module, the contracted top spring will restore its deformation to push the upper swing frame. This causes the No. 2 pressure frame to initially move downward, first pulling the upper swing frame downward, and then pulling the upper pressure roller downward. When the lower pressure roller moves away from under the upper pressure roller, the upper pressure roller just moves down and presses against the area on the backlight module that has been pressed by the lower pressure roller. At this time, the upper pressure roller is positioned near the center of the backlight module. Simultaneously, the upper convex plate on the upper swing frame and the lower convex plate on the lower swing frame are pressed together under the action of the top spring to form a single unit. If the upper swing frame cannot move further down, the first pressing frame continues to move down to continue pushing the lower pressing roller to press the backlight module. At this time, the second pressing frame, which continues to move down, will push the upper swing frame to move in an arc around the central axis, that is, around the center of the curved LCD panel. This will in turn drive the upper pressing roller on the upper carrier to move in an arc to press the other side of the backlight module. This allows the pressing starting areas of the upper and lower pressing rollers to overlap, so as to avoid the phenomenon that the pressing interface area of ​​the upper and lower pressing rollers is not pressed. This ensures that the curved LCD panel and the backlight module are fully pressed together, and guarantees the quality of assembly and bonding. Attached Figure Description

[0017] The following description is intended to disclose the invention and enable those skilled in the art to implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0018] like Figures 1-9The illustrated automatic assembly and bonding device for a liquid crystal display module includes a housing 1. A lifting component is installed at the center of the bottom surface of the housing 1. An arc-shaped support 2 is mounted on the lifting component. The curvature of the arc-shaped support 2 matches the curvature of a curved liquid crystal display panel 35, allowing the arc-shaped support 2 to fully contact and support the curved liquid crystal display panel 35. The center of the curved liquid crystal display panel 35 and the center of the arc-shaped support 2 are collinear. Four positioning angles 34 are arranged in a square array at the upper end of the arc-shaped support 2. The space between the four positioning angles 34 matches the size of the curved liquid crystal display panel 35, allowing the positioning angles 34 to engage with the curved liquid crystal display panel 35. The corners of the display panel 35 and the backlight module 36 are positioned to ensure they are fully aligned, and the center of the curved LCD display panel 35 and the center of the arc-shaped support 2 are collinear. A pusher is installed at the rear edge of the inner bottom surface of the housing 1. The two ends of the pusher are respectively inclinedly connected to the second pressure frame 11 and the first pressure frame 10. The inclination direction of the second pressure frame 11 is opposite to that of the first pressure frame 10, which allows the download rack 21 and the loading rack 19 to move in opposite directions. The second pressure frame 11 is located behind the first pressure frame 10 to ensure that they do not obstruct each other. A central shaft 29 is installed near the rear edge of the inner bottom surface of the housing 1. The center of the central shaft 29 is aligned with the center of the arc-shaped support 2. The centers of the arc-shaped support 2 are collinear. When the arc-shaped support 2 moves upward a certain distance, its center will be collinear with the center of the central axis 29. This means the center of the central axis 29 and the center of the curved LCD panel 35 are collinear, allowing the upper pressing roller 20 and lower pressing roller 22 to fully contact and press the backlight module 36 together when they move in an arc around the central axis 29. A front swing bracket 28 is rotatably mounted on the front of the outer surface of the central axis 29. A download bracket 21 extends from the upper end of the front swing bracket 28, and a lower pressing roller 22 is mounted on the lower end of the download bracket 21. The frame 21 serves to support the lower pressing roller 22. An upper swing frame 12 is elastically installed on the rear of the outer surface of the central shaft 29. An upper carrier frame 19 is fixedly installed at the upper end of the upper swing frame 12. An upper pressing roller 20 is installed at the lower end of the upper carrier frame 19. The upper carrier frame 19 serves to support the upper pressing roller 20. The upper pressing roller 20 is located above and to the side of the lower pressing roller 22, so that when the upper pressing roller 20 moves down, it just presses on the area of ​​the backlight module 36 that has been pressed by the lower pressing roller 22, and is located near the middle of the backlight module 36. The first pressing frame 10 is connected to the lowering frame 21, and the second pressing frame 11 is connected to the upper carrier frame 19.

[0019] The two ends of the central shaft 29 are inlaid with bearing seats 30. The lower end of the bearing seat 30 is fixed to the housing 1. The bearing seat 30 serves to support the central shaft 29. Positioning claws 37 are fixedly installed on both sides of the bearing seat 30. One of the positioning claws 37 rests on the front swing frame 28. The positioning claw 37 can limit the front swing frame 28 and the lower swing frame 18 when resetting, so that they remain upright.

[0020] The lower end of the upper swing frame 12 extends with an upper convex plate 13. The lower swing frame 18 is rotatably mounted on the rear part of the outer surface of the central shaft 29. The upper end of the lower swing frame 18 extends with a lower convex plate 15. The upper convex plate 13 and the lower convex plate 15 serve as a connection. Two guide posts 14 are symmetrically fixedly mounted on the lower end of the upper convex plate 13. The lower convex plate 15 is slidably mounted on the outer surface of the guide posts 14. The guide posts 14 serve as a guide. Another positioning claw 37 rests on the lower swing frame 18.

[0021] A top cap 17 is coaxially embedded at the lower end of the guide post 14. A top-closing spring 16 is wound around the outside of the guide post 14. The top-closing spring 16 can push the top cap 17 downward, thereby driving the upper swing frame 12 downward. The upper end of the top-closing spring 16 is fixed to the lower end of the lower convex plate 15, and the lower end of the top-closing spring 16 is fixed to the upper end of the top cap 17. The top-closing spring 16 is used to press the upper convex plate 13 on the upper swing frame 12 and the lower convex plate 15 on the lower swing frame 18 together to form a whole. When the top closing spring 16 is in a contracted state, the contracted top closing spring 16 will restore its deformation to push the upper swing frame 12, so that when the second pressure frame 11 first moves down, it will first drive the upper swing frame 12 down, and then drive the upper pressure roller 20 down. When the lower pressure roller 22 moves away from under the upper pressure roller 20, the upper pressure roller 20 just moves down and presses on the area of ​​the backlight module 36 that has been pressed by the lower pressure roller 22. At this time, the upper pressure roller 20 is in a position close to the middle of the backlight module 36.

[0022] A first slot 23 extends from the side of the download rack 21. The lower end of the first pressure frame 10 is rotatably installed inside the first slot 23. The first slot 23 facilitates connection with the first pressure frame 10. A second slot 24 extends from the side of the upper rack 19. The lower end of the second pressure frame 11 is rotatably installed inside the second slot 24. The second slot 24 facilitates connection with the second pressure frame 11. The opening direction of the second slot 24 is opposite to the opening direction of the first slot 23, which can accommodate the connection between the second pressure frame 11 and the first pressure frame 10 with opposite tilt directions. The second slot 24 is located behind the first slot 23.

[0023] The pushing component includes a rod seat 26 fixedly installed at the rear edge of the inner bottom surface of the housing 1. A T-shaped slider 5 is slidably installed inside the rod seat 26. A threaded rod 25 is rotatably installed between the upper and lower end faces inside the rod seat 26. The rod seat 26 serves to support the threaded rod 25 and provide a sliding surface for the T-shaped slider 5. The threaded rod 25 extends through the lower end of the rod seat 26. The T-shaped slider 5 is screwed onto the outer surface of the threaded rod 25. The threaded rod 25 drives the T-shaped slider 5 to move. The front end of the T-shaped slider 5... The device is inlaid with a non-circular frame 6, and a Z-shaped frame 7 is fixedly installed at the end of the non-circular frame 6. The non-circular frame 6 serves to fix the Z-shaped frame 7. A second connecting frame 9 extends from one end of the Z-shaped frame 7. The upper end of the first pressing frame 10 is rotatably connected to the second connecting frame 9. The second connecting frame 9 facilitates the connection of the first pressing frame 10. A first connecting frame 8 extends from the other end of the Z-shaped frame 7. The upper end of the second pressing frame 11 is rotatably connected to the first connecting frame 8. The first connecting frame 8 facilitates the connection of the second pressing frame 11.

[0024] A servo motor 27 is fixedly installed at the lower end of the rod base 26. The output end of the servo motor 27 is fixed to the lower end of the threaded rod 25. The servo motor 27 drives the threaded rod 25 to rotate.

[0025] The lifting component includes a servo cylinder 3 fixedly installed at the center of the bottom surface inside the housing 1. A lifting platform 32 is fixedly installed at the telescopic end of the servo cylinder 3. The servo cylinder 3 drives the lifting platform 32 to move up and down. A guide sleeve 31 is embedded through the corner of the lifting platform 32. The lifting platform 32 supports the arc-shaped support 2. A guide rod 4 is slidably installed inside the guide sleeve 31. The cooperation between the guide sleeve 31 and the guide rod 4 guides the lifting platform 32. The guide rod 4 extends from the upper and lower ends of the guide sleeve 31. The lower end of the guide rod 4 is fixed to the housing 1. Two fixed brackets 33 extend symmetrically from the lower end of the arc-shaped support 2. The fixed brackets 33 serve as a connection and support. The lower end of the fixed brackets 33 is fixed to the upper end of the lifting platform 32.

[0026] During bonding, the curved LCD panel 35 is placed on the arc-shaped support 2, and then the backlight module 36 with optical adhesive is placed on the curved LCD panel 35. At this time, the positioning angle 34 engages at the corner of the curved LCD panel 35 and the backlight module 36 to position them, ensuring that the two are fully aligned and that the center of the curved LCD panel 35 and the center of the arc-shaped support 2 are collinear. Then, the servo push cylinder 3 works to move the arc-shaped support 2 upward a certain distance. At this time, the lower pressing roller 22 presses down on the middle of the backlight module 36, and the center of the arc-shaped support 2 and the center of the central axis 29 are collinear. Then, the servo motor 27 works to drive the threaded rod. Rotation 25 causes the T-shaped slider 5 to move downwards, which in turn drives the first pressure frame 10 and the second pressure frame 11 to move downwards simultaneously. At this time, the downward-moving first pressure frame 10 will push the lower pressing roller 22 on the download frame 21 to move in an arc around the central axis 29, that is, around the center of the curved liquid crystal display panel 35. This allows the lower pressing roller 22 to move from the middle of the backlight module 36 towards one end of the backlight module 36 to press the backlight module 36 and one side area of ​​the curved liquid crystal display panel 35. During this process, the contracted top pressing spring 16 will restore its deformation to push the upper swing frame 12, so that the second pressure frame 11 will first drive the upper swing frame 12 when it begins to move downwards. The swing frame 12 moves downward, which in turn drives the upper pressing roller 20 downward. When the lower pressing roller 22 moves away from below the upper pressing roller 20, the upper pressing roller 20 just moves down and presses against the area on the backlight module 36 that has been pressed by the lower pressing roller 22. At this time, the upper pressing roller 20 is in a position close to the middle of the backlight module 36. At the same time, the upper convex plate 13 on the upper swing frame 12 and the lower convex plate 15 on the lower swing frame 18 are pressed together by the top spring 16 to form a whole, preventing the upper swing frame 12 from moving further downward. Then, the T-shaped slider 5 continues to drive the first pressing frame 10 downward to continue pushing the lower pressing roller 22 to press the backlight module 36. As the second pressure frame 11 continues to move downward, it will push the upper swing frame 12 to move in an arc around the central axis 29, that is, around the center of the curved liquid crystal display panel 35. This will cause the upper pressing roller 20 on the upper carrier 19 to move in an arc, so that the upper pressing roller 20 moves towards the other end of the backlight module 36 from the position near the middle of the backlight module 36 and located in the area after the lower pressing roller 22 has pressed it. This will press the backlight module 36 and the curved liquid crystal display panel 35 together, so that the backlight module 36 and the curved liquid crystal display panel 35 are fully pressed together and assembled and bonded together.
