Description

Technical Field

[0001] This utility model relates to the technical field of LCD screen alignment and bonding, specifically to a vacuum adsorption device for LCD screen alignment and bonding. Background Technology

[0002] LCD screen alignment and bonding is a key process in the production of LCD display modules. High-precision equipment is used to precisely align and bond the LCD screen with components such as touch screens, polarizers, and backlight modules to ensure that the LCD screen achieves high-quality display effects in various devices and adapts to different environmental requirements.

[0003] According to the publicly available announcement (CN220305589U), a device for fully laminating curved surfaces of automotive LCD screens is disclosed. This technology discloses a system comprising: a main support frame; a positioning and adsorption unit above the main support platform; a lamination drive unit above the positioning and adsorption unit; a three-axis correction stage on the right side of the positioning and adsorption unit; and cameras distributed at the top of the main support frame. The positioning and adsorption unit includes a positioning linear module, a positioning moving frame, and a vacuum adsorption stage. The lamination drive unit includes a transverse linear module, a longitudinal linear module, a rotary adjustment motor, a rotary support, and a vacuum adsorption pressure head. This system features a compact overall design, an automated production mode, and full lamination of concave, flat, and convex glass covers. It operates in an atmospheric environment, reducing production cycle time and equipment costs. It also solves the lamination problems caused by the pre-bending and springback of LCDs. Furthermore, the vacuum adsorption fixture replaces adhesive, reducing consumable costs.

[0004] However, in the aforementioned comparative documents, the vacuum adsorption pressure head is positioned in a fixed manner. Since the LCD screens are of different sizes, the fixed position may cause the adsorption point of the small screen to be suspended, while the large screen may be stretched in some areas, resulting in uneven force and unstable adsorption. Furthermore, it may cause the LCD screen to deform or fall off unexpectedly during the moving and bonding process, which greatly increases the processing cost.

[0005] Therefore, this utility model provides a vacuum adsorption device for aligning and bonding LCD screens. Utility Model Content

[0006] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a vacuum adsorption device for aligning and bonding LCD screens.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a vacuum adsorption device for aligning and bonding an LCD screen, comprising a worktable and an adsorption slide. A support is fixedly connected to the side end of the adsorption slide. An adjusting motor is fixedly connected inside the support. A small gear is fixedly connected to the output end of the adjusting motor. The lower end of the small gear is rotatably connected to the support. A large gear ring is rotatably connected inside the support. The surface of the small gear meshes with the large gear ring. A turntable is fixedly connected to the lower end of the large gear ring. A first rotating rod is fixedly connected to the side end of the turntable. A second rotating rod is rotatably connected to the end of the first rotating rod. A sliding groove is provided at the lower end of the support. A slider is slidably connected to the support through the sliding groove. Adsorption pipes are fixedly connected inside the support and the slider, respectively. The end of the second rotating rod is rotatably connected to the adsorption pipe. A conical suction head is provided at the lower end of the adsorption pipe. A flexible air tube is connected to the upper end of the conical suction head.

[0008] In a preferred embodiment, a support is fixedly connected to the upper end of the workbench, and a shelf is fixedly connected to the upper end of the workbench.

[0011] The technical effect of adopting the above-mentioned further solution is that the first moving rod is made to rotate inside the first slide rail by setting it up.

[0012] In a preferred embodiment, a second slide rail is slidably connected inside the first slide rail, and the surface of the first moving rod is threadedly connected to the second slide rail.

[0013] The technical effect of adopting the above-mentioned further solution is that the second slide rail can slide inside the first slide rail by setting it up.

[0014] In a preferred embodiment, a longitudinal moving motor is fixedly connected to the upper end of the second slide rail, a second moving rod is rotatably connected inside the second slide rail, the output end of the longitudinal moving motor is fixedly connected to the second moving rod, the surface of the adsorption slide table is slidably connected to the second slide rail, and the surface of the second moving rod is threadedly connected to the adsorption slide table.

[0016] In a preferred embodiment, the adsorption pipe has a rotating groove inside, and the adsorption pipe is slidably connected to a spherical rotating shaft through the rotating groove.

[0017] The technical effect of adopting the above-mentioned further solution is that the spherical rotating shaft can be set to adjust its angle according to the curvature of the LCD screen.

[0018] In a preferred embodiment, the spherical rotating shaft has an internal ventilation hole, and a conical suction head is fixedly connected to the lower end of the spherical rotating shaft.

[0019] The technical effect of adopting the above-mentioned further solution is that the conical suction head can still maintain communication with the adsorption pipe after the angle is adjusted.

[0020] This invention provides a vacuum adsorption device for aligning and bonding LCD screens. It has the following advantages:

[0021] The turntable rotates, causing the slider to slide on the slide groove. This allows the conical suction head to be adjusted to the optimal suction point according to the size of the LCD screen, resulting in a more even and distributed force on the LCD screen.

Even after the angle of the conical suction head is adjusted, it can still maintain communication with the adsorption pipe through the vent hole to adsorb the LCD screen, thus improving the applicability of the device and enabling adaptive adjustment to the curvature of the screen.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] like Figure 1 - Figure 4As shown, this embodiment provides a technical solution: a vacuum adsorption device for aligning and bonding LCD screens, including a worktable 1 and an adsorption slide 2. A support 3 is fixedly connected to the side end of the adsorption slide 2, which carries the adsorption parts. An adjusting motor 4 is fixedly connected inside the support 3, and a small gear 5 is fixedly connected to the output end of the adjusting motor 4. The adjusting motor 4 drives the small gear 5 to rotate. The lower end of the small gear 5 is rotatably connected to the support 3, and the small gear 5 is adapted to the support 3. A large gear ring 6 is rotatably connected inside the support 3, and the inner circumference of the support 3 is equal to the outer circumference of the large gear ring 6. The surface of the small gear 5 meshes with the large gear ring 6, and the small gear 5 is adapted to the large gear ring 6. A turntable 7 is fixedly connected to the lower end of the large gear ring 6, and four first rotating rods 8 are fixedly connected to the side end of the turntable 7. A second rotating rod 9 is rotatably connected to the end of the first rotating rod 8, and the inner circumference of the first rotating rod 8 is equal to the outer circumference of the second rotating rod 9. A sliding groove 10 is opened at the lower end of the support 3. The platform 3 is slidably connected to the slider 11 via the slide groove 10. The slide groove 10 and the slider 11 are adapted to each other. Adsorption pipes 12 are fixedly connected inside the platform 3 and the slider 11 respectively. There are five adsorption pipes 12. The end of the second rotating rod 9 is rotatably connected to the adsorption pipe 12. The inner circumference of the second rotating rod 9 is equal to the outer circumference of the adsorption pipe 12. A conical suction head 13 is provided at the lower end of the adsorption pipe 12. The upper end of the conical suction head 13 is connected to the flexible air tube 14. By adjusting the rotation of the motor 4, the small gear 5 is driven to rotate, thereby causing the large gear ring 6 to rotate inside the platform 3, which in turn drives the turntable 7 to rotate. The turntable 7 and the slider 11 are connected through the first rotating rod 8 and the second rotating rod 9, so that when the turntable 7 rotates, it drives the slider 11 to slide on the slide groove 10. The conical suction head 13 is adjusted to the optimal adsorption point according to the size of the LCD screen, so that the force on the LCD screen is more evenly distributed, ensuring stable adsorption and preventing the LCD screen from deforming or accidentally falling when moving due to imbalance of force.

[0031] like Figure 1 As shown: A bracket 15 is fixedly connected to the upper end of the workbench 1, and a shelf 16 is fixedly connected to the upper end of the workbench 1. There are two shelves 16, and the LCD screen can be placed on the shelf 16 to perform adsorption and alignment operations.

[0032] like Figure 1 As shown: A first slide rail 17 is fixedly connected to the surface of the bracket 15, and a transverse moving motor 18 is fixedly connected to the side end of the bracket 15. A first moving rod 19 is rotatably connected inside the first slide rail 17. The inner circumference of the first slide rail 17 is equal to the outer circumference of the first moving rod 19. The output end of the transverse moving motor 18 is fixedly connected to the first moving rod 19. When the transverse moving motor 18 rotates, it causes the first moving rod 19 to rotate inside the first slide rail 17.

[0033] like Figure 1As shown: The first slide rail 17 is internally slidably connected to the second slide rail 20. The first slide rail 17 and the second slide rail 20 are adapted to each other. The surface of the first moving rod 19 is threadedly connected to the second slide rail 20. The first moving rod 19 and the second slide rail 20 are adapted to each other. When the first moving rod 19 rotates, the second slide rail 20 slides inside the first slide rail 17 under the constraint of the first moving rod 19 and the first slide rail 17, thereby moving the adsorbed LCD screen to the designated position for adhesion.

[0034] like Figure 1 As shown: A longitudinal moving motor 21 is fixedly connected to the upper end of the second slide rail 20. A second moving rod 22 is rotatably connected inside the second slide rail 20. The inner circumference of the second slide rail 20 is equal to the outer circumference of the second moving rod 22. The output end of the longitudinal moving motor 21 is fixedly connected to the second moving rod 22. The surface of the adsorption slide 2 is slidably connected to the second slide rail 20. The adsorption slide 2 is adapted to the second slide rail 20. The surface of the second moving rod 22 is threadedly connected to the adsorption slide 2. The second moving rod 22 is adapted to the adsorption slide 2. When the longitudinal moving motor 21 drives the second moving rod 22 to rotate, the adsorption slide 2 slides inside the second slide rail 20 under the constraint of the second moving rod 22 and the second slide rail 20, thereby moving and adsorbing the LCD screen.

[0035] like Figure 4 As shown: The adsorption pipe 12 has a rotating groove 23 inside. The adsorption pipe 12 is slidably connected to a spherical rotating shaft 24 through the rotating groove 23. The rotating groove 23 and the spherical rotating shaft 24 are adapted to each other. When the spherical rotating shaft 24 is subjected to pressure, it will rotate along the rotating groove 23 inside the adsorption pipe 12, so that the spherical rotating shaft 24 adjusts the angle according to the curvature of the LCD screen.

[0036] like Figure 4 As shown: The spherical rotating shaft 24 has a vent hole 25 inside. The lower end of the spherical rotating shaft 24 is fixedly connected to a conical suction head 13. When the conical suction head 13 is squeezed by the LCD screen, and the LCD screen has a curvature, it forces the conical suction head 13 to drive the spherical rotating shaft 24 to rotate, so that the conical suction head 13 fits the LCD screen more closely. After the angle of the conical suction head 13 is adjusted, it can still maintain communication with the adsorption pipe 12 through the vent hole 25 to adsorb the LCD screen.

[0037] Working principle:

[0038] like Figure 1 - Figure 4 As shown:

[0039] In use: Adjust the motor 4 to rotate, which drives the small gear 5 to rotate, thereby causing the large gear ring 6 to rotate inside the support 3, which in turn drives the turntable 7 to rotate. The turntable 7 and the slider 11 are connected by the first rotating rod 8 and the second rotating rod 9, so that while the turntable 7 rotates, it drives the slider 11 to slide on the slide groove 10. Adjust the conical suction head 13 to the optimal suction point according to the size of the LCD screen, so that the force on the LCD screen is more evenly distributed and the suction is stable. After the adjustment is completed, when the longitudinal moving motor 21 drives the second moving rod 22 to rotate, the suction slide 2 slides inside the second slide rail 20 under the constraint of the second moving rod 22 and the second slide rail 20. It moves downward and uses the conical suction head 13 and the soft air tube 14 to suction the LCD screen and then lift it up. Then the transverse moving motor 18 rotates, causing the first moving rod 19 to rotate inside the first slide rail 17. When the first moving rod 19 rotates, the second slide rail 20 slides inside the first slide rail 17 under the constraint of the first moving rod 19 and the first slide rail 17, thereby moving the suctioned LCD screen to the designated position for adhesion.

[0040] When the LCD screen has a curvature, the conical suction head 13 is forced to contact the screen, causing the spherical rotating shaft 24 to be under pressure, thus rotating along the rotating groove 23 inside the adsorption channel 12. Finally, the spherical rotating shaft 24 adjusts its angle according to the curvature of the LCD screen, so that the conical suction head 13 fits the LCD screen more closely. Even after the angle is adjusted, the conical suction head 13 can still maintain communication with the adsorption channel 12 through the vent 25 to adsorb the LCD screen.
