Description

Technical Field

[0001] The present application relates to the field of display screen production technology, and in particular to a frustum display screen laminating device and method. Background Art

[0002] Flexible OLEDs (organic light-emitting diodes) are flexible OLED display devices fabricated on flexible substrates such as plastic, metal foil, and glass. In recent years, with the rapid development of flexible OLED displays, they have been widely used in various industries.

[0003] After the flexible substrate is manufactured, it needs to be bonded to the protective cover plate through tools such as bonding devices to form the final display device. However, with the application of flexible OLED displays in the wearable and smart home industries, the product form of flexible OLED displays has undergone tremendous changes. The product form of flexible OLED displays has changed from a purely flat or purely curved 2D product or a simple 3D form of a flat surface + a simple curved surface to a complex 3D form with unique characteristics of the wearable and smart home industries: such as a truncated cone. However, the bonding equipment currently available on the market is all designed for bonding 2D products with purely flat or purely curved surfaces or simple 3D forms of a flat surface + a simple curved surface, and cannot achieve bonding of complex 3D truncated cone display products. Therefore, a new bonding device and bonding method are needed to bond truncated cone display products. Summary of the Invention

[0004] In order to solve the problem of being unable to bond a frustum display screen product, the present application provides a frustum display screen bonding device and bonding method.

[0005] In the first aspect, the present application provides a frustum display screen bonding device, which adopts the following technical solution:

[0006] A frustum display screen laminating device includes a vacuum operating box, a jig disposed within the vacuum operating box for securing a panel, and an operating table for securing a glass cover plate. A vacuum assembly for evacuating the vacuum operating box is disposed outside the vacuum operating box. The jig is disposed on the top of the vacuum operating box, and the operating table is disposed at the bottom of the vacuum operating box in a lifting manner. The jig and the operating table are located in the same vertical direction.

[0007] The fixture includes a fixing table, one end of which is connected to the vacuum operation box, the end of the fixing table away from the vacuum operation box is configured in a frustum shape, and a sticky layer for adhering the panel is provided on the surface of the fixing table, and a detachment component for detaching the panel from the fixing table is provided inside the fixing table.

[0008] By adopting the above technical solution, after the staff sticks the panel to the frustum-shaped end of the fixing table, the panel is transformed from a flat state into a 3D frustum. At the same time, the frustum-shaped glass cover is placed on the operating table in the vacuum operating box, so that the center line of the panel coincides with the center line of the glass cover. The operating table is driven close to the fixing table, and the glass cover and panel are bonded. The bonded product is then separated from the fixing table using a release component, thus completing the bonding production of the frustum-shaped OLED.

[0009] Optionally, the disengagement assembly includes a core mold and a vacuum part, a mounting hole is opened in the middle of the fixed platform, the core mold is installed in the mounting hole, the end face of the core mold away from the top wall of the vacuum operation box is set to be a spherical surface, and the lowest point of the spherical surface is in contact with the horizontal inner wall of the mounting hole, and the fixed platform is opened with a vacuum cavity and is connected to the vacuum part.

[0010] By adopting the above technical solution, before the staff drives the operating table close to the fixed table to complete the lamination of the truncated cone-shaped OLED, they use a vacuum part to evacuate the middle of the fixed table, causing the fixed table to elastically deform, and the bottom end face of the fixed table to continuously align with the spherical surface of the core mold, thereby converting the bottom end face of the panel from a circular plane to a spherical surface. As a result, as the glass cover on the operating table continues to approach, the glass cover first aligns with the lowest point of the panel's spherical surface. During the lamination process, air is continuously inflated into the vacuum chamber of the fixed table, and the panel and glass cover continuously diffuse from point contact to surface contact, reducing the generation of bubbles and improving product quality. After the panel and glass cover are bonded, the interior of the fixed table returns to normal pressure. At this time, the fixed table is vacuumed again, and the fixed table is deformed to fit the core mold. The bonded product is partially separated from the fixed table. The product can be completely separated from the fixed table by removing the fixed table.

[0011] Optionally, the vacuum component includes a first connecting pipe and a first air pump, the first air pump is installed outside the vacuum operating table, one end of the first connecting pipe is connected to the fixed table, and the other end of the first connecting pipe is connected to the first air pump.

[0012] By adopting the above technical solution, after the panel is attached to the truncated cone-shaped end of the fixing table and before being attached to the glass cover plate, the first air pump is activated to convert the atmospheric pressure inside the vacuum chamber of the fixing table into a vacuum pressure, thereby causing the fixing table to undergo elastic deformation and attach to the core mold inside, so that the circular plane of the panel is converted into a spherical surface that is convenient for attaching to the glass cover plate and for separating the attached product from the fixing table. The operation is simple and convenient.

[0013] Optionally, an auxiliary bonding component is also provided in the vacuum operation box, and the auxiliary bonding component includes a clamp and a sliding member. The clamp is slidably connected to the vacuum operation box through the sliding member. The sliding direction of the clamp is perpendicular to the sliding direction of the operating table, and the clamp clamps both sides of the fixed table.

[0014] By adopting the above technical solution, the staff starts the first air pump to deform the fixed platform. After the bottom of the panel is converted into a spherical surface, the sliding part controls the sliding of the clamp so that the clamp clamps the deformed peripheral wall of the fixed platform, assisting in maintaining the deformation state of the fixed platform, thereby improving the spherical shape retention effect of the panel, which is beneficial to the subsequent bonding of the panel and the glass cover.

[0015] Optionally, the vacuum assembly includes a second air pump, the vacuum operation box is connected to a second connecting pipe, and the other end of the second connecting pipe is connected to the second air pump.

[0016] By adopting the above technical solution, when the staff is bonding the panel and the glass cover, they can start the second air pump to convert the vacuum operating box into a vacuum environment, avoiding the generation of bubbles during the bonding process, and simplifying the operation.

[0017] Optionally, the fixture includes a six-axis robotic arm, the vacuum operating box includes a box body and a box cover, the box cover is fixedly connected to the peripheral wall of the six-axis robotic arm, and the output end of the six-axis robotic claw is provided with a connecting seat for connecting to the fixed platform.

[0018] By adopting the above technical solution, the staff can control the movement of the six-axis instrument arm to make the fixed table stick the flat panel to the fixed table, move the fixed table and the operating table opposite to each other and move the fixed table into the vacuum operation box, and fix the position of the fixed table after the box cover and the box body of the vacuum operation box are closed, which facilitates the subsequent vacuum operation of the vacuum operation box. After the bonding is completed, the fixed table separated from the bonded product can be automatically taken out of the vacuum operation box. The whole operation process is convenient and fast.

[0019] Optionally, a cylinder is provided in the vacuum operating box, an output end of the cylinder is fixedly connected to the operating table, and the cylinder drives the operating table to move toward the fixed table.

[0020] By adopting the above technical solution, the staff can activate the cylinder to drive the operating table close to the fixed table, thereby making the glass cover plate close to the panel and fit the glass cover plate.

[0021] In a second aspect, the present application provides a method for laminating a truncated cone display screen, which adopts the following technical solution:

[0022] A method for laminating a frustum-shaped display screen comprises attaching a panel to the frustum-shaped end of a fixing table, placing a glass cover plate on an operating table, evacuating a vacuum operating box using a vacuum component, and driving the operating table close to the fixing table in the vacuum environment of the vacuum operating box to laminarize the panel and the glass cover plate; finally, separating the laminating product from the fixing table using a release component.

[0023] By adopting the above technical solution, the staff will stick the panel to the conical end of the fixed table, convert the vacuum operating box into a vacuum environment, and drive the operating table close to the fixed table. The glass cover on the operating table will be bonded to the panel on the fixed table. Finally, the separation component will be used to gradually separate the bonded product from the fixed table.

[0024] In summary, this application includes at least one of the following beneficial technical effects:

[0025] 1. After the panel is adhered to the frustum-shaped end of the fixing table, the panel transforms from a flat state into a 3D frustum. Simultaneously, the frustum-shaped glass cover is placed on the operating table inside the vacuum operating chamber, aligning the center lines of the panel and the glass cover. The operating table is then moved closer to the fixing table, allowing the glass cover to bond to the panel. The bonded product is then separated from the fixing table using a release assembly, completing the frustum-shaped OLED bonding process.

[0026] 2. After the staff sticks the panel to the fixed table, before the glass cover plate on the operating table is brought closer, the middle part of the fixed table is evacuated with a vacuum part, and the fixed table undergoes elastic deformation, and the bottom end face of the fixed table continuously fits with the spherical surface of the core mold, thereby converting the bottom end face of the panel from a circular plane to a spherical surface. After the glass cover plate approaches the fixed table, the glass cover plate first fits with the lowest point of the panel's spherical surface. During the fitting process, air is continuously inflated into the vacuum chamber of the fixed table, and the panel and the glass cover plate continuously diffuse from point contact to surface contact. After the panel and the glass cover plate are fitted, the inside of the fixed table becomes normal pressure. At this time, the fixed table is vacuumed again, and the fixed table is deformed to fit the core mold. The bonded product is partially separated from the fixed table, and the product can be completely separated from the fixed table by removing the fixed table. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] The following is combined with Figure 1-3 This application is described in further detail.

[0032] The embodiment of the present application discloses a frustum display screen bonding device. Figure 1 A frustum display screen bonding device includes a vacuum operation box 1, a jig 2 for fixing a panel 9 arranged in the vacuum operation box 1, and an operating table 3 for fixing a glass cover plate 10. The operating table 3 uses an existing vacuum adsorption table to adsorb and fix the glass cover plate 10. The jig 2 is set on the top of the vacuum operation box 1, and the operating table 3 is set at the bottom of the vacuum operation box 1 by a cylinder 8. The jig 2 and the operating table 3 are located in the same vertical direction. After the staff fixes the panel 9 and the glass cover plate 10 on the jig 2 and the operating table 3 respectively, they drive the operating table 3 close to the jig 2 in the vacuum environment of the vacuum operation box 1, thereby bonding the glass cover plate 10 to the panel 9.

[0033] refer to Figure 1 The vacuum operation box 1 includes a box body 11 and a box cover 12. A vacuum assembly for evacuating the vacuum operation box 1 is provided on the outside of the vacuum operation box 1. The vacuum assembly includes a second air pump 7. A connection hole is formed through the vacuum operation box 1, and a second connecting pipe 6 is connected to the connection hole. The other end of the second connecting pipe 6 is connected to the second air pump 7. The second air pump 7 can be a conventional air pump. During the bonding process between the panel 9 and the glass cover 10, the second air pump 7 is activated to evacuate air, thereby achieving a vacuum environment in the vacuum operation box, thereby preventing bubbles from forming when the panel 9 and the glass cover 10 are bonded together, thereby improving product quality.

[0034] refer to Figure 1 as well as Figure 2The fixture 2 includes a six-axis robotic arm 22, a connecting base 23, and a fixing platform 21. A through-hole is provided in the middle of the box cover 12, and the box cover 12 is fixedly mounted on the six-axis robotic arm 22. The connecting base 23 is fixed to the output end of the robotic arm. The connecting base 23 includes a connecting plate 231 and a clamping plate 232. The connecting plate 231 is configured in a circular shape, and the end face of the connecting plate 231 is fixed to the output end of the robotic arm. The clamping plate 232 is L-shaped. A threaded hole is provided on the L-shaped vertical section of the clamping plate 232, and a bolt for fixing to the connecting base 23 is threadedly connected in the threaded hole. The fixed platform 21 includes a mounting cake 211 and a fixing column 212 that are connected and fixed to each other. The diameter of the mounting cake 211 is larger than the diameter of the fixing column 212 and smaller than the diameter of the connecting plate 231. After the staff fits the mounting cake 211 with the connecting seat 23, the inner wall of the L-shaped short side of the clamping block is brought into contact with the end face of the mounting cake 211 away from the connecting seat 23, and bolts are installed so that the clamping block clamps the mounting cake 211 stably, thereby fixing the mounting cake 211 and the six-axis robot arm 22.

[0035] The end of the fixing post 212 away from the mounting cake 211 is set to a truncated cone shape. The mounting cake 211 and the fixing post 212 are both made of a silicone material with a weak adhesive surface, which is convenient for sticking the flat panel 9 into a truncated cone shape. Figure 3 As shown, the panel 9 includes a circular base 91 and an outer ring band 92. The six-axis robotic arm 22 drives a fixed post 212 with a weakly adhesive surface to revolve around the center of the outer ring band 92 while simultaneously rotating, tracing the outer ring band 92 and the circular base 91 onto the outer surface of the frustum-shaped end of the fixed post 212. This converts the flat panel 9 into a frustum-shaped panel 9 and adheres it to the frustum-shaped display end of the fixed post 212. After the six-axis robotic arm 22 places the fixed platform with the panel 9 bonded to it into the vacuum operating chamber 1, it drives the operating platform 3 close to the jig 2 to complete the bonding operation between the glass cover 10 and the panel 9.

[0036] refer to Figure 2 In order to improve the bonding effect between the panel 9 and the glass cover 10 and facilitate the separation operation, a separation component 4 for separating the panel 9 from the fixing platform 21 is provided in the fixing platform 21. The separation component 4 includes a core mold 41 and a vacuum component 42. A mounting hole 213 is provided in the middle of the fixing platform 21. The core mold 41 is installed in the mounting hole 213. The end surface of the core mold 41 away from the top wall of the vacuum operation box 1 is set as a spherical surface, and the lowest point of the spherical surface abuts the horizontal inner wall of the mounting hole 213. The fixing platform 21 is provided with a vacuum chamber 214 and is connected to the vacuum component 42. The vacuum component 42 includes a first connecting pipe 421 and a first air pump 422. The first air pump 422 uses an existing vacuum pump and is installed on the side wall of the vacuum operation platform 3. The two ends of the first connecting pipe 421 are respectively connected to the first air pump 422 and the vacuum chamber 214 of the fixing platform 21.

[0037] refer to Figure 2 Since the fixing column 212 is made of silicone material, after the staff sticks the panel 9 to the end of the truncated display screen of the fixing column 212, the six-axis robotic arm 22 aligns the center line of the fixing column 212 with the center line of the operating table 3, and continues to move until the box cover 12 and the box body 11 are sealed. Start the first air pump 422, the interior of the fixed column 212 is in a vacuum state, and the fixed column 212 undergoes elastic deformation due to the influence of air pressure, and then fits with the internal core mold 41. The circular plane at the bottom of the fixed column 212 fits with the spherical surface of the core mold 41, so that the circular base surface 91 of the bottom of the fixed column 212 and the panel 9 bulge outward. At the same time, start the second air pump 7 to make the inside of the box 11 a vacuum operating environment. When the staff drives the glass cover plate 10 on the operating table 3 close to the panel 9, the glass cover plate 10 first fits with the lowest point of the panel 9. At this time, positive pressure is continuously added. In the process of restoring the original shape of the fixed column 212, the circular base surface 91 of the panel 9 continues to become flat, and then the point contact between the panel 9 and the glass cover plate 10 continues to diffuse into surface contact, until the panel 9 and the glass cover plate 10 are fully fitted.

[0038] refer to Figure 2 In order to improve the deformation effect of the panel 9 into a convex shape, an auxiliary bonding component 5 is also provided in the vacuum operation box 1. The auxiliary bonding component 5 includes a clamping claw 51 and a sliding member 52. The clamping claw 51 is configured as two clamping plates 232. The clamping claw 51 is slidably connected to the vacuum operation box 1 through the sliding member 52. The sliding member 52 includes a double-headed threaded rod 521, a sliding rod 522 and a motor 523. A mounting plate is symmetrically connected to one side wall of the vacuum operation box 1. The two clamping plates 232 are sequentially provided with threaded holes and through holes along the length direction. The double-headed threaded rod 521 is threadedly connected to the clamping plate 232 through the threaded hole and the two ends are respectively rotatably connected to the two mounting plates through bearings. One end of the double-headed threaded rod 521 passes through the connecting plate 231 and is connected to the output end of the motor 523. The sliding rod 522 passes through the through hole on the clamping plate 232 and the two ends are respectively fixed to the two mounting plates. After the staff uses the first air pump 422 to elastically deform the fixing column 212, they start the motor 523, the double-headed threaded rod 521 rotates, and the sliding rod 522 limits the rotation of the splint 232. The two splints 232 clamp the two sides of the fixing platform 21 along the length direction of the sliding rod 522, thereby maintaining the slightly deformed state of the fixing column 212 until the panel 9 contacts the glass cover 10. In the process of continuously filling the vacuum chamber 214 with positive pressure, the two splints 232 continue to move away from each other until the panel 9 and the glass cover 10 are fully fitted and the splint 232 is completely separated from the fixing column 212.

[0039] An embodiment of the present application discloses a method for bonding a truncated cone display screen. First, a flat panel 9 is adhered to the truncated cone display screen surface of a fixed column 212. The six-axis robotic arm 22 is used to drive the fixed column 212 with a weakly sticky surface to revolve around the center of the outer ring belt 92 and rotate at the same time, respectively, and the outer ring belt 92 and the circular base surface 91 are respectively conformed to the outer surface of the truncated cone display screen end of the fixed column 212, thereby converting the flat panel 9 into a truncated cone-shaped panel 9 and adhering it to the truncated cone display screen end of the fixed column 212.

[0040] After the panel 9 is adhered to the fixing column 212, the six-axis robot arm 22 moves to the top of the box body 11 so that the center line of the fixing column 212 coincides with the center line of the glass cover 10 on the operating table 3, and moves toward the operating table 3 until the box cover 12 is tightly fitted to the box body 11.

[0041] Start the first air pump 422, the interior of the fixed column 212 is in a vacuum state, and the fixed column 212 is elastically deformed by the air pressure and fits with the internal core mold 41. The circular base surface 91 at the bottom of the fixed column 212 fits with the spherical surface of the core mold 41, so that the circular base surface 91 panel 9 at the bottom of the fixed column 212 bulges outward. At this time, the staff starts the motor 523, and the double-headed threaded rod 521 rotates. The two clamps 232 clamp the two sides of the fixed platform 21 along the length direction of the sliding rod 522 to maintain the slightly deformed state of the fixed column 212.

[0042] Start the second air pump 7 to create a vacuum operating environment in the box 11. When the staff starts the cylinder 8, the glass cover 10 on the operating table 3 is driven close to the panel 9. The glass cover 10 first fits with the lowest point of the panel 9. At this time, positive pressure is continuously added to the fixing column 212. In the process of restoring the original shape of the fixing column 212, the circular base surface 91 of the panel 9 is continuously flattened, and the double-headed threaded rod 521 rotates in the opposite direction to drive the clamping plate 232 away from the fixing column 212, thereby causing the point contact between the panel 9 and the glass cover 10 to continue to expand into surface contact until the panel 9 and the glass cover 10 are fully fitted.

[0043] After the bonding is completed, when it is necessary to separate the bonded product from the fixed column 212, first, positive pressure is filled into the box body 11 so that the interior of the box body 11 becomes normal pressure, and the first air pump 422 is started to make the interior of the fixed column 212 a vacuum state. The fixed column 212 is elastically deformed by the air pressure and bonded to the internal core mold 41. Since the bonding force between the panel 9 and the glass cover 10 is greater than the bonding force between the panel 9 and the fixed column 212, during the deformation process of the fixed column 212, the peripheral side of the bonded product is partially separated from the surface of the fixed column 212. At this time, the fixed column 212 is driven by the six-axis robot arm 22 to move in a direction away from the operating table 3, thereby completely separating the product from the fixed column 212.

[0044] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
