Detailed implementation manners

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without making creative efforts shall fall within the protection scope of the present invention.

[0023] Please refer toFigures 1-12 , the present invention provides a device for attaching a flexible OLED panel to a curved cover plate, including a base 1, a support frame 5, and an assembly table 2. The assembly table 2 and the support frame 5 are respectively installed at the top of the base 1. A curved cover plate body 3 is provided at the top of the assembly table 2, and a flexible OLED panel body 4 is provided at the bottom of the support frame 5.

[0024] Among them, the flexible OLED panel body 4 is arranged at the bottom of the support frame 5, and the curved cover plate body 3 is arranged at the top of the assembly table 2, so as to position the flexible OLED panel body 4 and the curved cover plate body 3. In this way, when driving the flexible OLED panel body 4 to move, precise attachment can be achieved, ensuring the complete effect of attachment.

[0025] In the technical solution of the embodiment of the present application, a fitting mechanism 6 is provided at the bottom of the support frame 5. The fitting mechanism 6 includes a bending component 65 arranged at the bottom of the support frame 5. The bending component 65 includes a roller component 655 for boosting pressure installed at the bottom of the support frame 5. The roller component 655 includes a cylindrical roller component 655 composed of a plurality of roller bodies 6561.

[0026] Among them, the roller component 655 is used to apply pressure to drive the flexible OLED panel body 4 to move, so as to achieve the fitting effect. At the same time, when the roller component 655 is in use, it can distribute the pressure on the flexible OLED panel body 4 more evenly, which helps to avoid excessive pressure on the local area of the panel, thereby reducing the risk of panel damage, such as indentation or cracking. At the same time, when the roller component 655 rolls on the flexible OLED panel body 4, it will apply a certain pressure to it and guide it to bend. The cylindrical structure composed of a plurality of roller bodies 6561 can more effectively disperse this pressure, so that the panel can be stressed more evenly during the bending process, thereby enhancing its flexibility.

[0027] In the technical solution of the embodiment of the present application, auxiliary components 66 are provided on both sides of the assembly table 2. The auxiliary components 66 include a support seat 661 installed on the side of the assembly table 2. An inclined sliding plate 663 for adjusting the angle is installed at the top of the support seat 661 through a limit screw 662. The flexible OLED panel body 4 slides on the surface of the inclined sliding plate 663. A light plate 664 for reducing friction is installed on the surface of the inclined sliding plate 663 close to the flexible OLED panel body 4.

[0028] Among them, when the flexible OLED panel body 4 faces the curved cover plate, the inclined slide plate 663 can assist the flexible OLED panel body 4 to bend, so that the flexible OLED panel can be pre-deformed slowly and stably before fitting. When the flexible OLED panel body 4 is fitted to the curved cover plate, it undergoes a certain amount of bending deformation, so that it will not cause damage or poor fitting effect due to excessive and rapid deformation of the panel; the use of the inclined surface of the light plate 664 can reduce the friction between the flexible OLED panel body 4 and the inclined slide plate 663 during bending, thereby reducing damage. Moreover, the light plate 664 is made of a heat-conducting material. Therefore, when friction occurs on the flexible OLED panel body 4, the heat flow can be dissipated in time, so as to ensure the stable bending deformation of the flexible OLED panel body 4 and reduce the interference of the external temperature.

[0029] In some other embodiments, the fitting mechanism 6 further includes a moving plate 61 rotatably installed at the bottom end of the support frame 5. A hydraulic cylinder 68 is installed at the top end of the support frame 5. The output shaft of the hydraulic cylinder 68 is fixedly connected to the moving plate 61. A bidirectional threaded rod 62 is rotatably installed at the bottom end of the moving plate 61. Two opposite threaded grooves for changing the position of the roller assembly 655 are formed on the outer surface of the bidirectional threaded rod 62. Two roller assemblies 655 are threadedly installed on the surface of the bidirectional threaded rod 62. Gears 63 are fixedly installed at both ends of the bidirectional threaded rod 62. A rack 64 is fixedly installed on the side surface of the assembly table 2. The rack 64 and the gears 63 are engaged with each other.

[0030] Among them, the hydraulic cylinder 68 can drive the moving plate 61 to move. The moving plate 61 drives the roller assembly 655 to move. When the roller assembly 655 moves, it will drive the bidirectional threaded rod 62 to move. The gears 63 at both ends of the bidirectional threaded rod 62 cooperate with the rack 64, which will cause the gears 63 to rotate. The rotation of the gears 63 drives the bidirectional threaded rod 62 to rotate. Through the bidirectional thread setting on the outer surface of the bidirectional threaded rod 62, the two fixing plates 651 on the outer surface of the bidirectional threaded rod 62 will move in opposite directions. At this time, the roller assemblies 655 will move in opposite directions. With the cooperation of the inclined slide plate 663, when the roller assemblies 655 apply pressure to the flexible OLED panel body 4, the pressure can be continuously dispersed, so as to reduce the over-deformation damage of the flexible OLED panel body 4, so that the flexible OLED panel body 4 can be pre-deformed slowly and stably before fitting, and avoid the damage of the flexible OLED panel body 4 caused by sharp bending.

[0031] In some other embodiments, a sliding assembly 69 is provided at the bottom end of the moving plate 61. The sliding assembly 69 includes a support rod 693 and a slide rod 691 installed at the bottom end of the moving plate 61 for limiting the roller assembly 655. A sliding sleeve 692 is slidably installed between the support rod 693 and the slide rod 691. The outer surface of the sliding sleeve 692 is fixedly connected to the roller assembly 655.

[0032] Among them, through the action of the support rod 693 and the slide rod 691, the roller assembly 655 can be limited, so that the roller assembly 655 can stably move horizontally, and further improve the stability of the roller assembly 655 to ensure the fitting accuracy of the flexible OLED panel body 4.

[0033] In some other embodiments, the bending assembly 65 further includes a fixing plate 651 threadedly mounted on the outer surface of the bidirectional threaded rod 62.

A telescopic rod 652 is installed between the fixing plate 651 and the long plate 654. The roller assembly 655 is arranged at the bottom end of the long plate 654.

[0034] Among them, when the roller assembly 655 presses on the flexible OLED panel body 4, the spring 653 can buffer the flexible OLED panel body 4, further reducing the damage caused by the pressing intensity, and at the same time improving the smoothness of the roller assembly 655 sliding on the surface of the flexible OLED panel body 4.

[0035] In some other embodiments, a constant temperature component 656 is arranged inside the roller assembly 655. The constant temperature component 656 includes a motor 6563 fixedly installed on the outer surface of the long plate 654. An annular groove 6562 is formed inside the roller body 6561.

And a sealing gasket 6564 for reducing heat flow loss is installed between every two roller bodies 6561.

[0036] Among them, by starting the motor 6563, the motor 6563 drives the heating tube 6565 to rotate inside the roller body 6561, so that the heat flow emitted by the heating tube 6565 can flow evenly and stably in the annular groove 6562 to ensure temperature balance, make the surface temperature of the flexible OLED panel body 4 uniform, and reduce the damage caused by the concentration of thermal stress on the surface of the flexible OLED panel body 4; the sealing gasket 6564 can reduce the loss of heat flow.

[0037] In some other embodiments, limiting components 67 are arranged on both sides of the flexible OLED panel body 4. The limiting components 67 include a rotating rod 671 fixedly installed at the bottom end of the long plate 654. A pulley 672 for limiting the flexible OLED panel body 4 is rotatably installed at the bottom end of the rotating rod 671. The pulley 672 slides on the side wall of the flexible OLED panel body 4.

[0038] Among them, by arranging two sets of pulleys 672 to slide on the side wall of the flexible OLED panel body 4, and cooperating with the roller assembly 655 and the inclined slide plate 663, the flexible OLED panel body 4 is concentrated at the top of the curved cover plate for movement, ensuring the fitting accuracy. At the same time, rolling can reduce frictional losses and improve the stability of fitting.

[0039] In some other embodiments, dust removal mechanisms 7 are arranged on both sides of the flexible OLED panel body 4. The dust removal mechanism 7 includes an air pump 75 installed at the top of the support frame 5. Air outlet plate assemblies 71 and air suction plate assemblies 73 for slit dust removal are respectively installed at both ends of the assembly table 2 close to the flexible OLED panel body 4. An air outlet pipe 72 is connected and installed between the output end of the air pump 75 and the air outlet plate assembly 71, and an air suction pipe 74 is connected and installed between the input end of the air pump 75 and the air suction plate assembly 73.

[0040] Among them, through the air outlet plate assembly 71 and the air suction plate assembly 73, dust removal and purification and air circulation are realized in the gap where the flexible OLED panel body 4 coincides with the curved cover plate body 3, which not only helps to keep the fitting surface clean, but also can reduce the temperature during the fitting process and reduce the influence of thermal stress on the panel.

[0041] In some other embodiments, the air suction plate assembly 73 includes an air suction plate body 731 installed on one side of the flexible OLED panel body 4. Activated crushed carbon 732 for filtering and reusing air is arranged inside the air suction plate body 731, and a plurality of conical holes 733 are formed on the surface of the air suction plate body 731 close to the flexible OLED panel body 4.

[0042] Among them, through the design of the activated crushed carbon 732 inside the air suction plate, the air can be filtered and reused to reduce secondary pollution to the flexible OLED panel body 4. The design of the conical holes 733 can prevent the loss of the activated crushed carbon 732 and ensure the adsorption effect of the activated crushed carbon 732.

[0043] In some other embodiments, a buffer mechanism 8 is arranged inside the assembly table 2.

[0044] Among them, when the curved cover plate body 3 is under pressure, through the resistance buffering of the viscoelastic damper 82, a resistance can be provided when the flexible OLED panel is attached to the curved cover plate body 3, reducing the damage to the curved cover plate body 3 caused by excessive pressure. It not only protects the curved cover plate body 3, but also can absorb the impact and vibration during the fitting process to a certain extent, further improving the stability and quality of the fitting.
