Description

Technical Field

[0001] This invention relates to the field of flexible OLED display technology, and more specifically to an automated attachment device for a carrier film for flexible OLED displays. Background Technology

[0002] Flexible OLED displays are an advanced display technology that uses organic light-emitting diodes built on a flexible substrate, allowing the screen to be bent, folded, or even rolled up. Compared with traditional rigid OLED displays, flexible OLEDs have advantages such as deformability, thinness, and low power consumption. In order to protect the screen from damage during the production process, a carrier film is often attached to the surface of the flexible OLED display.

[0003] Currently, when attaching a carrier film to a flexible OLED display, the flexible OLED display is usually placed on a bottom suction base, and then the carrier film is adsorbed on the upper suction base and moved down to attach the carrier film to the flexible OLED display. However, in the actual film application process, simply using the upper suction base to squeeze the carrier film onto the flexible OLED display results in poor film application. If a rolling shaft is used for rolling, the carrier film will detach from the suction base, making it prone to wrinkling or shifting during the rolling process. Based on this, an automated carrier film application device for flexible OLED displays is proposed to solve the above-mentioned defects. Summary of the Invention

[0004] The purpose of this invention is to provide an automated attachment device for a carrier film for flexible OLED displays, in order to overcome the aforementioned shortcomings in the technology.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an automated attachment device for a carrier film of a flexible OLED display, comprising:

[0006] The mounting frame has a controller installed on its side wall and a bottom adsorption seat at the bottom of its interior. An upper adsorption assembly is installed on the upper interior of the mounting frame via a telescopic component. The upper adsorption assembly includes a first mounting plate. An electric telescopic rod is installed at each of the four corners near the lower end of the first mounting plate. An upper adsorption seat is installed at the bottom of the electric telescopic rod. A gap is provided between the two upper adsorption seats.

[0007] A lifting assembly is installed on one side inside the mounting frame, and a reciprocating rolling assembly is installed on the lifting assembly. A rolling element is installed on the reciprocating rolling assembly, and the rolling element is located above the bottom adsorption seat.

[0008] Preferably, the lifting assembly includes a second hydraulic cylinder and a second mounting plate, wherein the second hydraulic cylinder is installed at the bottom inside the mounting frame, and the second mounting plate is installed at the top of the second hydraulic cylinder.

[0009] Preferably, the reciprocating rolling assembly includes:

[0010] A servo motor is mounted on the upper surface of the second mounting plate;

[0011] A circular rotating plate, which is mounted on the output end of a servo motor via a rotating shaft;

[0012] A protruding post is fixed to the edge of the circular rotating plate opposite to the servo motor.

[0013] A connecting strip, wherein a guide groove is provided inside the connecting strip, and the protrusion passes through the guide groove;

[0014] A guide structure is provided to prevent the connecting strip from disengaging from the guide groove and to maintain the reciprocating motion of the connecting strip when the circular rotating plate rotates.

[0015] Preferably, the guide structure includes:

[0016] Two guide rods are symmetrically connected to both sides of the connecting strip;

[0017] Two support bars, one end of which is symmetrically connected to the second mounting plate, and the other end of which extends close to the guide rod;

[0018] Two collars are provided, with one end of the support bar connected to the other collar. The collar has an axial groove through which the guide rod passes.

[0019] Preferably, the rolled element comprises:

[0020] A protrusion, which is fixed to the bottom end of the connecting strip;

[0021] A connecting rod, one end of which is connected to the outside of the protrusion;

[0022] A pressure roller, which is rotatably mounted on the outside of the connecting rod.

[0023] Preferably, the telescopic component is a first hydraulic cylinder or a pneumatic cylinder.

[0024] Preferably, each of the upper adsorption seats is equipped with a second pneumatic suction cup, the lower end face of the second pneumatic suction cup is flush with the lower end face of the upper adsorption seat, and the upper end of the second pneumatic suction cup is connected to an air tube.

[0025] Preferably, a plurality of first pneumatic suction cups are installed inside the bottom adsorption base, and the upper end surface of the first pneumatic suction cups is flush with the upper end surface of the bottom adsorption base.

[0026] Preferably, the diameter of the circular rotating plate is not less than the length of the bottom adsorption seat.

[0027] Preferably, the gap width between the upper adsorption seats on both sides is greater than the diameter of the pressure roller.

[0028] The technical effects and advantages provided by the present invention in the above technical solution are as follows:

[0029] 1. This invention sets up four upper adsorption seats equipped with pneumatic suction cups. Each upper adsorption seat is independently controlled and can be raised and lowered independently via an electric telescopic rod. When using pressure rollers for rolling, it is not necessary to remove the entire carrier film from the upper adsorption seat. The restriction can be released end by end, which can avoid wrinkles or displacement of the carrier film during the rolling process.

[0030] 2. By setting up a reciprocating rolling assembly, the reciprocating rolling assembly drives the pressure roller to move back and forth. First, the laterally moving pressure roller can be used to make one end of the carrier film fully adhered. Then, after releasing the upper adsorption seat on the other side, the servo motor can be controlled to run continuously to use the pressure roller to roll back and forth on the carrier film, ensuring the adhesion quality and avoiding the generation of air bubbles.

[0031] 3. The present invention utilizes a rotating circular plate in conjunction with a guide structure to drive the pressure roller to move back and forth. Compared with simply using a drive component to drive the pressure roller to move back and forth, this structure is more efficient and flexible, and can ensure the uniformity of rolling.

[0044] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0045] Figures 1-3All figures are schematic diagrams of the overall structure of the present invention. As shown in the figures, the automatic attachment device for the carrier film of the flexible OLED display includes a mounting frame 1 and a lifting assembly. A controller 2 is installed on the side wall of the mounting frame 1, and a bottom adsorption seat 3 is provided at the bottom of the mounting frame 1. Multiple first pneumatic suction cups 4 are installed in the bottom adsorption seat 3. The multiple first pneumatic suction cups 4 are evenly distributed to ensure that the flexible OLED display is subjected to uniform suction force. The upper end surface of the first pneumatic suction cup 4 is flush with the upper end surface of the bottom adsorption seat 3 to ensure that the flexible OLED display is flat after being placed on the bottom adsorption seat 3, which is conducive to the accurate attachment of the carrier film. An upper adsorption assembly is installed at the upper end of the interior of the mounting frame 1 through a telescopic component. The telescopic component can be a first hydraulic cylinder 5, a pneumatic cylinder, or other automatic telescopic component that can achieve lifting. The upper adsorption assembly includes a first mounting plate 7. The first mounting plate 7 is mounted on... An electric telescopic rod 9 is installed at the bottom of the telescopic component and at the four corners near the lower end of the first mounting plate 7. The electric telescopic rod 9 is electrically connected to the controller 2. An upper adsorption seat 10 is installed at the bottom of the electric telescopic rod 9. There is a gap between the two upper adsorption seats 10. A second pneumatic suction cup 13 is installed in each upper adsorption seat 10. The lower end of the second pneumatic suction cup 13 is flush with the lower end of the upper adsorption seat 10 to ensure that the carrier film is flat after being placed on the lower end of the upper adsorption seat 10. An air pipe 8 is connected to the upper end of the second pneumatic suction cup 13. The air outlet of the air pipe 8 can be connected to a common air pump through a five-way valve. A solenoid valve is installed on each air pipe 8 to realize the control of a single air pipe 8, so that the second pneumatic suction cup 13 in each upper adsorption seat 10 can be controlled independently. Each upper adsorption seat 10 can be raised and lowered independently through the electric telescopic rod 9.

[0046] See Figure 1 and Figure 2 As shown, the lifting assembly is installed on one side inside the mounting bracket 1, and a reciprocating rolling assembly 6 is installed on the lifting assembly. A rolling component is installed on the reciprocating rolling assembly 6. The rolling component is located above the bottom adsorption seat 3. The rolling component can roll the carrier film on the flexible OLED display to ensure the adhesion quality and avoid the generation of air bubbles. The outer layer of the rolling component is preferably a flexible pad cover to avoid the carrier film from being scratched by the overly hard rolling component.

[0047] Among them, see Figure 2 As shown, the lifting assembly includes a second hydraulic cylinder 11 and a second mounting plate 12. The second hydraulic cylinder 11 is installed at one end of the bottom of the mounting frame 1, and the second mounting plate 12 is installed at the top of the second hydraulic cylinder 11. The hydraulic movement of the second hydraulic cylinder 11 is used to realize the lifting and lowering of the second mounting plate 12, thereby realizing the lifting and lowering of the reciprocating rolling assembly 6, so that the rolling part moves closer to or away from the bottom adsorption seat 3.

[0048] In a specific embodiment of the present invention, see [reference]. Figure 4 , Figure 5 and Figure 7 As shown, the reciprocating rolling assembly 6 includes:

[0049] Servo motor 61 is electrically connected to controller 2 and is mounted on the upper surface of second mounting plate 12.

[0050] A circular rotating plate 62 is mounted on the output end of the servo motor 61 via a rotating shaft, and the diameter of the circular rotating plate 62 is not less than the length of the bottom adsorption seat 3.

[0051] The protruding post 67 is fixed to the edge of the circular rotating plate 62 on the side facing away from the servo motor 61.

[0052] Connecting bar 65, with guide groove 68 inside the connecting bar 65, and protrusion 67 penetrating through guide groove 68;

[0053] The guide structure is used to restrict the connecting bar 65 from disengaging from the guide groove 68 and to maintain the reciprocating motion of the connecting bar 65 when the circular rotating plate 62 rotates.

[0054] See Figure 5 and Figure 6 As shown, the guide structure includes:

[0055] Two guide rods 66 are symmetrically connected to both sides of the connecting strip 65;

[0056] Two support bars 63, one end of which is symmetrically connected to the second mounting plate 12, and the other end of which extends close to the guide rod 66;

[0057] Two collars 64, one end of a support bar 63 is connected to a collar 64, and the collar 64 has an axial groove 641 through which a guide rod 66 passes.

[0058] When the circular rotating plate 62 rotates, the eccentric protrusion 67 can only move within the guide groove 68, so that the guide groove 68 can drive the connecting bar 65 to move back and forth. During the back and forth movement of the connecting bar 65, the guide rod 66 always passes through the through groove 641 to ensure the smooth movement of the rolled part.

[0059] See Figure 5 As shown, the rolled part includes:

[0060] Protrusion 15, protrusion 15 is fixed to the bottom end of connecting strip 65;

[0061] Connecting rod 14, one end of which is connected to the outside of protrusion 15;

[0062] The pressure roller 16 is rotatably mounted on the outside of the connecting rod 14. The gap between the two upper adsorption seats 10 is wider than the diameter of the pressure roller 16, so that the pressure roller 16 can pass through the gap.

[0063] Through the above technical solution:

[0064] In practical use, the flexible OLED display to be coated is placed on the upper surface of the bottom suction base 3 and fixed in place by the first pneumatic suction cup 4. Then, the four upper suction bases 10 are used to jointly adhere the carrier film. Subsequently, the controller 2 controls the first hydraulic cylinder 5 to rise, causing the first mounting plate 7 to move downwards, so that the carrier film moves down and is coated on the upper surface of the flexible OLED display. At this time, the second pneumatic suction cups 13 in the two upper suction bases 10 at one end can be disconnected first, and the controller 2 controls the electric telescopic rod 9 to move the two upper suction bases 10 upwards. Then, the controller 2 can start the servo motor 61 on the second mounting plate 12, and use the servo motor 61 to input... The output end drives the circular rotating plate 62 to rotate. Since the connecting strip 65 is restricted to the outside of the protrusion 67 by the guide structure, the protrusion 67 can drive the connecting strip 65 to move laterally during the rotation of the circular rotating plate 62. In conjunction with the hydraulic movement of the second hydraulic cylinder 11, the pressure roller 16 moves down to adhere to the carrier film. The laterally moving pressure roller 16 can first make one end of the carrier film completely adhered. Then, the two upper adsorption seats 10 on the other side are released, and the electric telescopic rod 9 moves the two upper adsorption seats 10 upward. After that, the servo motor 61 can be controlled to run continuously to use the pressure roller 16 to roll back and forth on the carrier film to ensure the adhesion quality and avoid the generation of air bubbles.

[0065] Among them, the four upper adsorption seats 10 are controlled individually. When using the pressure roller 16 for rolling, it is not necessary to completely remove the upper adsorption seat 10 from its restriction. The restriction can be released end by end, which can avoid wrinkles or displacement of the carrier film during the rolling process.

[0066] Secondly, using a circular rotating plate 62 in conjunction with a guide structure to drive the pressure roller 16 to move back and forth is more efficient and flexible than simply using a driving component (telescopic rod, cylinder, etc.) to drive the pressure roller 16 to move back and forth. It does not require the carrier film to be completely removed from the adsorption limit and can ensure the uniformity of rolling.

[0067] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
