Description

Technical Field

[0001] This utility model relates to the field of flexible display technology, and in particular to a bonding device for a transparent LED flexible display. Background Technology

[0002] As display technology evolves towards lightweight, flexible, and high-transparency designs, transparent flexible LED displays are widely used in smart terminals, automotive displays, and outdoor advertising due to their advantages such as bendability, high light transmittance, and low power consumption. One of the core manufacturing steps involves precisely bonding the flexible LED display module to a carrier such as a glass substrate or flexible substrate. This bonding process requires no air bubbles, no misalignment, and no damage to the transparent electrodes and flexible substrate of the display.

[0003] In existing technology, such as Chinese Patent Publication No. CN221221059U, a feeding assembly is included. This assembly comprises a bracket, a third motor, a lead screw, a slide table, an electric telescopic rod, a feeding rack, a vacuum suction cup, a vacuum pump, a connecting pipe, a first laser sensor, and a second laser sensor. The third motor is mounted on one side of the bracket, with one end fixedly connected to one end of the lead screw. The slide table is slidably connected to the outer wall of the lead screw. This invention uses two sets of conveyor belts to transport a capacitive display screen and a thin-film package respectively. The vacuum suction cup picks up the thin-film package, and the third motor drives the lead screw to rotate, moving the package above the display screen. The electric telescopic rod then adheres the package to the display screen surface, and a pressure plate presses the two together. This eliminates the need for manual placement of the display screen and package, making operation simple and convenient, saving time, improving bonding efficiency, and reducing the workload of workers.

[0004] While the above-mentioned solution has the advantages mentioned above, its disadvantages are as follows: the pressure plate of the device is a rigid flat plate with a large weight, which exerts significant pressure and impact on the flexible screen, easily causing damage to the screen. The flat plate surface lacks cushioning and venting design, resulting in uneven pressure distribution during bonding and difficulty in air expulsion, which can easily form air bubbles between the screen and the bonding surface, reducing the bonding quality. At the same time, rigid contact may also cause excessive local stress on the flexible screen, leading to damage. Furthermore, there are no adjustment and positioning components inside the material tank, making it unable to adapt to display substrates of different specifications. The substrate is prone to positional misalignment during placement, resulting in inaccurate bonding positions and affecting the bonding effect. Utility Model Content

[0055] 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.

[0056] Example 1:

[0057] Please see Figures 1-5 This embodiment provides a transparent LED flexible display screen bonding device, the specific idea of ​​which is as follows:

[0058] A transparent LED flexible display screen bonding device includes a base 1, and the transparent LED flexible display screen bonding device also includes: a support frame 2, two limiting bars 4, a second conveyor belt 3, a first conveyor belt 7, two storage slots 15, four sliding grooves 14, four sliders 12, four U-shaped frames 8, and a buffer pressure component.

[0059] A support frame 2 is fixedly installed on one side of the top of the base 1.

[0060] In addition, two limiting bars 4 are set on both sides of the inner cavity of the base 1. The distance between the two limiting bars 4 can be manually adjusted according to the size of the display substrate to form a positioning boundary that adapts to different specifications of substrates.

[0061] In addition, a second conveyor belt 3 is rotatably installed at the bottom of the inner cavity of the base 1, and a first conveyor belt 7 is rotatably installed on one side of the top of the inner cavity of the base 1, with the first conveyor belt 7 located above the second conveyor belt 3 and the two side limit bars 4.

[0062] The base 1 has two storage slots 15 on both sides of the middle of its inner cavity. The two storage slots 15 are located at the top of the second conveyor belt 3, and the two limit bars 4 are located inside the two storage slots 15.

[0063] In addition, the bottom of the base 1 is provided with four sliding grooves 14 in two symmetrical groups, and four sliders 12 are slidably installed in the two groups of sliding grooves 14 respectively.

[0064] The base 1 has four U-shaped frames 8 arranged symmetrically in two groups on both sides. The bottom of the four U-shaped frames 8 passes through the bottom of both sides of the base 1 and slides with the bottom of the base 1. One side of the bottom of each frame is connected to the corresponding slider 12. The top of the four U-shaped frames 8 passes through the top of both sides of the base 1 and slides with it. One side of the top of each frame is connected to two symmetrically arranged limiting bars 4. The limiting bars 4 are slidably arranged on both sides of the base 1 and located on the top of the second conveyor belt 3.

[0065] In addition, the bottom of the support frame 2 is equipped with a pressure buffer.

[0066] As examples, in this embodiment, the buffer pressure component includes: a pressure plate 5, a plurality of honeycomb slots 9, an elastic silicone layer 10, a plurality of venting grooves 11, and an electric push rod 6.

[0067] The pressure plate 5 is located at the bottom of the support frame 2, and the interior of the pressure plate 5 is a hollow structure. The hollow structure reduces the pressure impact of the pressure plate 5 on the flexible screen.

[0068] In addition, the bottom of the pressure plate 5 has multiple equally spaced honeycomb-shaped slots 9.

[0069] Among them, an elastic silicone layer 10 is also installed at the bottom of the pressure plate 5 to achieve pressure buffering.

[0070] In addition, the bottom of the elastic silicone layer 10 has multiple cross-distributed venting grooves 11, which can guide the air out during the bonding process and reduce the generation of air bubbles.

[0071] Among them, an electric push rod 6 is fixedly installed on the top of the support frame 2, and the output end of the electric push rod 6 passes through the top of the support frame 2 and is connected to the top of the pressure plate 5.

[0072] In this embodiment, the pressure plate 5 adopts a hollow structure and has honeycomb-shaped slots 9, which effectively reduces the impact caused by its own weight. The bottom elastic silicone layer 10 forms a flexible contact during bonding, which avoids damage to the screen due to excessive local stress. The venting groove 11 at the bottom of the elastic silicone layer 10 can guide the air between the screen and the substrate to be discharged during bonding, reduce air bubble residue, and ensure tight bonding.

[0073] Example 2:

[0074] Please see Figures 1-5 Based on Example 1, this example provides a transparent LED flexible display screen bonding device, the specific concept of which is as follows:

[0075] The transparent LED flexible display bonding device also includes: four support bases 18, multiple anti-static rubber pads 23 and a driving component.

[0076] Among them, four support seats 18 are fixedly installed at the four corners of the bottom of the base 1.

[0077] In addition, multiple antistatic rubber pads 23 are evenly attached to the outer surfaces of the second conveyor belt 3 and the first conveyor belt 7 in sections to increase the friction when the substrate is placed and reduce displacement deviation during the conveying process.

[0078] Among them, the two slides 14 are equipped with driving components.

[0079] As examples, in this embodiment, the driving components include: a bidirectional lead screw 13, a limiting rod 22, an L-shaped groove 21, a first bevel gear 16, a second bevel gear 17, a rotating shaft 20, and a motor 19.

[0080] Two bidirectional lead screws 13 are rotatably installed in the two slide grooves 14, which pass through the corresponding two sliders 12 and are threadedly connected to them.

[0081] Among them, limit rods 22 are fixedly installed in the other two slides 14, which pass through the corresponding two sliders 12 and slide with them.

[0082] In addition, an L-shaped groove 21 is provided on one side of the bottom of the base 1, and the L-shaped groove 21 is located between the two sliding grooves 14.

[0083] The L-shaped groove 21 is provided with a first bevel gear 16 and a second bevel gear 17 that mesh with each other, wherein the first bevel gear 16 is fixed to the middle of the bidirectional lead screw 13.

[0084] In addition, a rotating shaft 20 is fixed in the middle of the second bevel gear 17, and the rotating shaft 20 is rotatably connected to the bottom of the base 1.

[0085] In addition, a motor 19 is fixedly installed on one side of the bottom of the base 1, and its output end is connected to the bottom end of the rotating shaft 20.

[0086] In this embodiment, when the motor 19 is running, it drives the rotating shaft 20 to rotate, which in turn drives the second bevel gear 17 to rotate. Since the second bevel gear 17 meshes with the first bevel gear 16 in the L-shaped groove 21, the power is transmitted to the bidirectional lead screw 13, causing the bidirectional lead screw 13 to rotate in the corresponding slide groove 14. When the bidirectional lead screw 13 rotates, it drives the slider 12 connected to it to slide along the slide groove 14 through the threaded transmission. Another set of sliders 12 moves synchronously under the guidance of the limiting rod 22. The sliders 12 drive the U-shaped frame 8 to move in conjunction, realizing the relative or opposite movement of the two limiting stops 4, and completing the size adaptation positioning.

[0087] Working principle:

[0088] In use, the substrate to be bonded is placed on the second conveyor belt 3, and the flexible display screen is placed on the first conveyor belt 7. The anti-static rubber pads 23, which are attached to the conveyor belt in sections, can prevent the substrate and the flexible screen from sliding and being damaged by static electricity. The drive unit is started, and the motor 19 outputs power through the rotating shaft 20 to the second bevel gear 17. The second bevel gear 17 meshes with the first bevel gear 16 in the L-shaped groove 21, driving the bidirectional lead screw 13 to rotate in the corresponding slide groove 14. When the bidirectional lead screw 13 rotates, the slider 12 threaded to it slides along the slide groove 14. At the same time, the limiting rod 22 guides and limits another set of sliders 12. The sliders 12 drive the limiting bars 4 on both sides to slide synchronously relative to each other or in opposite directions through the U-shaped frame 8. The spacing is adjusted according to the substrate size to form a precise positioning boundary. Excess structure can be stored in the storage groove 15. After positioning, the second conveyor belt 3 transports the substrate to the bonding station, and the first conveyor belt 7 simultaneously transports the flexible display screen to the corresponding position above the substrate.

[0089] The buffer pressure component is activated, and the electric push rod 6 outputs power to push the pressure plate 5 downward. The hollow structure inside the pressure plate 5, together with the honeycomb groove 9 at the bottom, reduces the impact of its own weight. When the bottom elastic silicone layer 10 comes into contact with the flexible display screen, it achieves pressure buffering to avoid excessive local stress. During the bonding process, the cross-venting groove 11 at the bottom of the elastic silicone layer 10 guides the air between the screen and the substrate to be discharged, reducing the residual air bubbles and ensuring a tight bond. After the bonding is completed, the electric push rod 6 drives the pressure plate 5 to reset, the drive component drives the limit stop 4 to retract, and the conveyor belt transports the bonded finished product to the next process. The device waits for the next bonding operation.
