Description

Technical Field

[0001] This utility model relates to the field of display panel technology, and in particular to a glass panel alignment device. Background Technology

[0002] Hybrid AMOLED is a new technology that applies thin-film encapsulation (TFE) to glass substrates, enabling a thinner and lighter design compared to traditional rigid AMOLED (Active-matrix organic light-emitting diode) panels. This technology reduces the thickness and weight of the display while maintaining the slim profile of a near-flexible AMOLED panel. More importantly, Hybrid AMOLED overcomes the common problems of edge wrinkling, surface unevenness, and insufficient strength and reliability found in large-size flexible AMOLED screens, integrating the advantages of both flexible and rigid AMOLED.

[0003] As market demand shifts towards larger display panels, the thickness of glass substrates is gradually decreasing to approximately 0.2mm. This results in products possessing both flexibility and rigidity, rendering traditional roller-based positioning systems inadequate for the new glass substrate form factor. For instance, during transport, the thinner material is more prone to bending, increasing the risk of inaccurate positioning, substrate scratches, and even screen breakage, thus impacting subsequent handling and cutting processes. Therefore, improvements are needed. Utility Model Content

It should be noted that, unless otherwise specified, the following embodiments and features described therein can be combined with each other.

[0066] It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of the present invention. Therefore, the drawings only show the components related to the present invention and are not drawn according to the number, shape and size of the components in actual implementation.

[0067] In the following description, numerous details are explored to provide a more thorough explanation of embodiments of the present invention. However, it will be apparent to those skilled in the art that embodiments of the present invention may be practiced without these specific details. In other embodiments, well-known structures and devices are shown in block diagram form rather than in detail to avoid obscuring embodiments of the present invention.

[0068] This utility model provides a glass panel alignment device, relating to the field of display panel technology, and can be applied to solve the technical problems of bending, scratching, and screen breakage that easily occur during the transmission and alignment of large-size Hybrid AMOLED thin glass panels. Detailed description is provided below through specific embodiments.

[0069] Please see Figure 1 , Figure 2In one embodiment of this utility model, the glass panel alignment device may include a fixed frame 100, a conveying component 200, a lifting component 300, and an alignment component 400. In this embodiment, the fixed frame 100 is provided with a loading area and an alignment area. The loading area is the loading position for the glass panel 500, typically placed there by upstream equipment. The alignment area is the position where the glass panel 500 is aligned; a robot arm of downstream equipment picks up the aligned glass panel 500 from the alignment area. The conveying component 200 can be installed on the fixed frame 100, and its conveying track can extend from the loading area to the alignment area. Thus, the conveying component 200 can receive the glass panel 500 from the loading area and convey it to the alignment area for alignment. The lifting component 300 can be installed at the alignment area of ​​the fixed frame 100 and can be used to support and lift the glass panel 500 conveyed by the conveying component 200. The alignment component 400 can be installed in the alignment area of ​​the fixed frame 100, and it can be used to align and standardize the glass panel 500 supported by the lifting component 300. Furthermore, after the alignment component 400 completes the alignment of the glass panel 500, the lifting component 300 will adsorb and fix the glass panel 500, and wait for the robot arm of the downstream equipment to grab the aligned glass panel 500.

[0070] Please see Figure 2 In one embodiment of this utility model, the fixed frame 100 may include a base frame 110 and a fixed base plate 120. The fixed base plate 120 is fixedly connected to the top of the base frame 110. A conveying assembly 200 may be mounted on the base frame 110. A lifting assembly 300 and an alignment assembly 400 may be mounted on the fixed base plate 120.

[0071] Please see Figure 3 In one embodiment of this utility model, the conveying assembly 200 may include a conveying frame 210, roller sets 220, and a conveying drive motor 230. The conveying frame 210 may be mounted on the base frame 110. Multiple roller sets 220 may be rotatably connected to the conveying frame 210. In this embodiment, the multiple roller sets 220 may be arranged at intervals along the conveying direction of the glass panel 500, thereby forming a conveying channel. The conveying drive motor 230 may be mounted on the conveying frame 210, and its output end may be connected to multiple roller sets for transmission, thereby driving all roller sets 220 to rotate synchronously.

[0072] Please see Figure 4In one embodiment of this utility model, the conveying frame 210 can be sequentially divided into a first region 211, a second region 212, and a third region 213 along a conveying direction perpendicular to the glass panel 500. The roller group 220 can be divided into a first roller group 221 and a second roller group 222. The rotation axis length of the first roller group 221 is the same as the width of the conveying frame 210. In this embodiment, the first roller group 221 is rotatably connected to the first region 211, the second region 212, and the third region 213. The rotation axis length of the second roller group 222 is shorter than that of the first roller group 221. In this embodiment, the second roller group 222 is rotatably connected to either the first region 211 or the third region 213, meaning that multiple second roller groups 222 can be respectively disposed on both sides of the conveying frame 210.

[0073] Please see Figure 5 In one embodiment of this utility model, the first roller group 221 may include a rotating shaft 2211, rollers 2212, and a magnetic wheel 2213. The two ends of the rotating shaft 2211 are connected to the conveying frame 210 via bearing seats 2214. Multiple rollers 2212 may be connected at intervals to the rotating shaft 2211. In this embodiment, the rollers 2212 may be UPE (Ultra-high molecular weight polyethylene) antistatic rollers. The magnetic wheel 2213 may be fixedly connected to one end of the rotating shaft 2211. In this embodiment, the second roller group 222 has a similar structure to the first roller group 221.

[0074] Please see Figure 4 , Figure 5 In one embodiment of this utility model, the conveying assembly 200 further includes a main drive shaft 240 and a driven drive shaft 250. The main drive shaft 240 and the driven drive shaft 250 are rotatably connected to the conveying frame 210. The main drive shaft 240 and the driven drive shaft 250 can be located on opposite sides of the conveying frame 210, and both are perpendicular to the rotation axis of the roller assembly 220. One end of the main drive shaft 240 can be connected to the output end of the conveying drive motor 230. The main drive shaft 240 is provided with multiple magnetic wheels, and these magnetic wheels correspond to either the magnetic wheel at one end of the first roller assembly 221 or the magnetic wheel at the end of the second roller assembly 222 located in the first region 211, thereby realizing magnetic wheel transmission. Figure 6 As shown, multiple magnetic wheels are mounted on the drive shaft 250, and each magnetic wheel corresponds to a magnetic wheel at the other end of the first roller group 221 or a magnetic wheel at the end of the second roller group 222 located in the third region 213, thereby realizing magnetic wheel transmission.

[0075] Therefore, the transmission drive motor 230 can drive the main drive shaft 240 to rotate, and further drive all the first roller groups 221 and the second roller group 222 located in the first region 211 to rotate synchronously through magnetic wheel transmission. The first roller group 221 can drive the driven shaft 250 to rotate through magnetic wheel transmission, and the driven shaft 250 drives the second roller group 222 located in the third region 213 to rotate synchronously. Thus, the synchronous rotation of all roller groups 220 can be achieved.

[0076] Please see Figure 4 In one embodiment of this invention, the rollers on adjacent roller groups 220 are arranged in a staggered pattern, forming a formation similar to a goose formation. In this embodiment, the conveying assembly 200 also includes multiple idler rollers 260. The idler rollers 260 are rotatably connected to the conveying frame 210. The multiple idler rollers 260 are evenly distributed on the conveying frame 210 to fill areas not covered by the first roller group 221 and the second roller group 222. Therefore, this invention, by adjusting the roller layout and adding idler rollers 260, achieves better support for the glass panel 500 and reduces bending deformation of the glass panel 500 during transport.

[0077] Please see Figure 3 In one embodiment of this invention, the conveying assembly 200 further includes a plurality of protective covers 270. Each protective cover 270 can be installed on one side of the conveying frame 210 and can be used to protect the main drive shaft 240 or the driven shaft 250. In this embodiment, the protective cover 270 has multiple windows for maintenance and repair.

[0078] Please see Figure 7 In one embodiment of this utility model, the worktable 310 is provided with a plurality of conveying clearance holes 311. Each conveying clearance hole 311 corresponds to a roller on a roller assembly 220, allowing the top of the roller to pass through. In this embodiment, when the lifting driver 320 does not drive the worktable 310 to rise, the top of the roller in the roller assembly 220 passes through the corresponding conveying clearance hole 311 and protrudes from the upper surface of the worktable 310. When the lifting driver 320 drives the worktable 310 to rise, the top of the roller in the roller assembly 220 will be lower than or flush with the upper surface of the worktable 310.

[0079] Please see Figure 2In one embodiment of this utility model, the lifting assembly 300 may include a worktable 310, a lifting driver 320, and an air guiding mechanism (not shown in the figure). The worktable 310 may be located in the alignment area and can be used to support the glass panel 500. The lifting driver 320 may be mounted on a fixed base plate 120, and its movable end may be connected to the worktable 310. The lifting driver 320 can be used to drive the worktable 310 and the glass panel 500 it supports to rise and fall. The air guiding mechanism may include multiple air nozzles and an air pump communicating with the air nozzles. The multiple air nozzles may be disposed on the surface of the worktable 310 that contacts the glass panel 500. In this embodiment, when the air pump supplies air to the air nozzles, an air flotation layer can be formed between the worktable 310 and the glass panel 500, thereby placing the glass panel 500 in an air-floating state; when the air pump draws air from the air nozzles, the air nozzles can attract and fix the glass panel 500.

[0080] Please see Figure 8 In one embodiment of this utility model, the workbench 310 is divided into multiple functional areas arranged in a grid layout to accommodate glass panels 500 of different sizes and material feeding directions. Specifically, the center of the workbench 310 is functional area A, which can be adapted to the size of a first glass panel 500 on its own. Functional areas B are located on both sides of functional area A along the feeding direction, and the combination of functional area A and the two sides of functional area B can accommodate the size of a second glass panel 500. Functional areas C are located on both sides of functional area A perpendicular to the feeding direction, and the combination of functional area A and the two sides of functional area C can accommodate the size of a third glass panel 500. Functional areas D are located at the four corners of the workbench 310, and the combination of all functional areas A, B, C, and D can accommodate the size of a fourth glass panel 500. The workbench 310 adopts the above-mentioned symmetrical design, and by selectively activating specific areas, flexible adjustments to product size and material feeding direction can be achieved.

[0081] Please see Figure 9In one embodiment of this utility model, the lifting driver 320 may include a lifting drive motor 321, a reducer 322, a commutator 323, a lifting transmission shaft 324, and a lifting actuator 325. The lifting drive motor 321 may be a servo motor, and its output end may be connected to the input end of the reducer 322. The reducer 322 may have at least two output ends. The number of commutators 323 corresponds to the number of output ends of the reducer 322, and the input end of each commutator 323 may be connected to one output end of the reducer 322. The commutator 323 may have at least two output ends, and each output end is connected to the input end of a lifting actuator 325 via a corresponding lifting transmission shaft 324. The output end of each lifting actuator 325 may abut against the bottom of the worktable 310. In this embodiment, the lifting actuator 325 may employ a rack and pinion structure or a screw mechanism. Therefore, the lifting drive motor 321 is connected to multiple lifting actuators 325 via the reducer 322, commutator 323, and lifting transmission shaft 324, thus forming a multi-axis synchronous lift. When the lifting drive motor 321 rotates, it can drive all the lifting actuators 325 to achieve synchronous lifting motion, thereby driving the worktable 310 to lift.

[0082] Please see Figure 2 , Figure 10 In one embodiment of this utility model, the alignment component 400 may include a longitudinal alignment mechanism 410 and a transverse alignment mechanism 420. The longitudinal alignment mechanism 410 may be mounted on the fixed frame 100 and located at the bottom of the worktable 310, with its movable end moving parallel to the conveying direction of the glass panel 500. The transverse alignment mechanism 420 may be mounted on the fixed frame 100 and located between the worktable 310 and the longitudinal alignment mechanism 410, with its movable end moving perpendicular to the conveying direction of the glass panel 500.

[0083] Please see Figure 10 In one embodiment of this utility model, the longitudinal alignment mechanism 410 may include a longitudinal guide rail 411, a longitudinal alignment telescopic rod 412, a longitudinal drive motor 413, a longitudinal slider 414, and a longitudinal synchronous belt 415. The longitudinal guide rail 411 can be mounted on a fixed base plate 120 and can be arranged parallel to the conveying direction of the glass panel 500. The longitudinal alignment telescopic rod 412 can be slidably connected to the longitudinal guide rail 411 via the longitudinal slider 414. There can be at least two longitudinal alignment telescopic rods 412, each located at one end of the longitudinal guide rail 411. The longitudinal drive motor 413 can be mounted on the longitudinal guide rail 411, and its output end can be connected to multiple longitudinal sliders 414 via the longitudinal synchronous belt 415 to drive the multiple longitudinal sliders 414 and the longitudinal alignment telescopic rods 412 thereon to move synchronously in opposite directions or in opposite directions.

[0084] Please see Figure 11 In one embodiment of this utility model, the longitudinal alignment telescopic rod 412 may include a lifting cylinder 4121, a longitudinal alignment adjusting plate 4122, and a longitudinal alignment rod 4123. The lifting cylinder 4121 can be mounted on the longitudinal slider 414. The longitudinal alignment adjusting plate 4122 can be mounted on the movable end of the lifting cylinder 4121. The number of longitudinal alignment rods 4123 may be at least two, each fixedly connected to one end of the longitudinal alignment adjusting plate 4122. The longitudinal alignment rods 4123 may be made of antistatic PEEEK (Polyetheretherketone) material, and their bottoms are threadedly connected to the longitudinal alignment adjusting plate 4122. By adjusting the installation position of the longitudinal alignment adjusting plate 4122, the actual position of the longitudinal alignment rods 4123 can be fine-tuned to ensure the consistency of product alignment and positioning.

[0085] In this embodiment, the axial direction of the longitudinal alignment rod 4123 can be perpendicular to the upper surface of the worktable 310. Therefore, the lifting cylinder 4121 can drive the longitudinal alignment adjustment plate 4122 and its multiple longitudinal alignment rods 4123 to move up and down. Specifically, when the lifting cylinder 4121 drives the longitudinal alignment adjustment plate 4122 to descend, it can cause the longitudinal alignment rods 4123 to descend below the upper surface of the worktable 310 to avoid the glass panel 500 during transport. When the lifting cylinder 4121 drives the longitudinal alignment adjustment plate 4122 to rise, it can cause the longitudinal alignment rods 4123 to protrude beyond the upper surface of the worktable 310, thereby performing a longitudinal alignment operation on the glass panel 500.

[0086] Please see Figure 10 In one embodiment of this utility model, the lateral alignment mechanism 420 may include a lateral guide rail 421, a lateral alignment guide rod 422, a lateral drive motor 423, a lateral slider 424, and a lateral synchronous belt 425. The lateral guide rail 421 can be mounted on the fixed base plate 120 via pads, and it can be arranged in a conveying direction perpendicular to the glass panel 500. The lateral alignment guide rod 422 can be slidably connected to the lateral guide rail 421 via the lateral slider 424. There can be at least two lateral alignment guide rods 422, each located at one end of the lateral guide rail 421. The lateral drive motor 423 can be mounted on the lateral guide rail 421, and its output end can be connected to multiple lateral sliders 424 via the lateral synchronous belt 425 to drive the multiple lateral sliders 424 and their lateral alignment guide rods 422 to move synchronously in opposite directions or in opposite directions.

[0087] Please see Figure 1In one embodiment of this utility model, the lateral alignment guide rod 422 may include a lateral alignment adjustment plate 4221 and a lateral alignment rod 4222. The lateral alignment adjustment plate 4221 is fixedly connected to the lateral slider 424 and can be arranged parallel to the conveying direction of the glass panel 500. The number of lateral alignment rods 4222 can be multiple, and they can be fixedly connected to the lateral alignment adjustment plate 4221 in groups of at least two. A group of four lateral alignment rods 4222 fixedly connected to the lateral alignment adjustment plate 4221 is suitable for various sizes of glass panels 500. The lateral alignment rods 4222 can be made of anti-static PEEK material, and their bottoms are threaded onto the lateral alignment adjustment plate 4221. By adjusting the installation position of the lateral alignment adjustment plate 4221, the actual position of the lateral alignment rods 4222 can be finely adjusted to ensure the consistency of product alignment and positioning. In this embodiment, the axial direction of the transverse straightening rod 4222 can be perpendicular to the upper surface of the worktable 310, and its top can protrude from the upper surface of the worktable 310, thereby performing a longitudinal straightening operation on the glass panel 500.

[0088] Please see Figure 7 In one embodiment of this utility model, the workbench 310 may have multiple alignment clearance holes 312 for the longitudinal alignment telescopic rod 412 and the transverse alignment guide rod 422 to pass through. The top of the transverse alignment guide rod 422 can pass through the corresponding alignment clearance hole 312, and the longitudinal alignment telescopic rod 412, after extending, passes through the corresponding alignment clearance hole 312, thereby achieving alignment of the glass panel 500.

[0089] Please see Figure 1 In one embodiment of this invention, the alignment device further includes a detection component 600. The detection component 600 may include a plurality of sensors mounted on the fixed frame 100. Each sensor can be used to detect whether the glass panel 500 is present in the loading area and the alignment area, and whether it has been conveyed into place.

[0090] In this embodiment, when the detection component 600 detects that the upstream equipment has placed the glass panel 500 in the loading area, the conveyor drive motor 230 starts, driving all the roller sets 220 to rotate synchronously, conveying the glass panel 500 from the loading area to the alignment area. After the detection component 600 detects that the glass panel 500 has moved into place, the conveyor drive motor 230 stops. The lifting drive 320 starts, driving the worktable 310 to rise, and after the worktable 310 receives the glass panel 500 on the roller set 220, it continues to rise a certain distance to stop in place. When the air pump of the air guiding mechanism vents air to the air nozzle, the worktable 310 and the glass panel 500 form an air-floating layer, so that the glass panel 500 is in an air-floating state. Then, the longitudinal alignment telescopic rod 412 extends to protrude from the upper surface of the worktable 310. The longitudinal alignment mechanism 410 and the transverse alignment mechanism 420 start to align the glass panel 500 from the longitudinal and transverse directions, respectively. After alignment is completed, when the air pump of the air guiding mechanism draws air from the air guide nozzle, the nozzle can attract and fix the glass panel 500, ensuring that the glass panel 500 no longer moves. The longitudinal alignment mechanism 410 and the transverse alignment mechanism 420 are reset. Finally, the robot arm of the downstream equipment descends and contacts the glass panel 500, adsorbing it through the suction cup on the robot arm. After a certain delay, the air pump of the air guiding mechanism vents air through the air guide nozzle to disengage the vacuum, and the glass panel 500 is removed by the downstream equipment. This completes one alignment operation, ensuring the consistency and accuracy of the position of panels of the same size when picking up and placing them.
