Description

Technical Field

[0001] The present invention relates to the technical field of polarizer lamination, and in particular to an integrated polarizer lamination jig. Background Art

[0002] Polarizer lamination is the process of precisely laminating a polarizer to a screen panel. Polarizers are usually made of a thin film material with special optical properties. They can block light waves in certain directions through physical principles and allow light in a specific direction to pass through, thereby achieving the polarization effect of light.

[0003] In the existing process, polarizers are attached to the display directly, which causes bubbles to form during the rolling process. Moreover, during the polarizer attachment process, the protective film needs to be removed in advance before attachment. If this process is too long, the protective film will be removed too early, which can easily lead to dust absorption and increase the risk of dust adhering to the polarizer and the display. Summary of the Invention

[0004] The object of the present invention is to provide an integrated polarizer lamination jig to address the above-mentioned deficiencies in the prior art.

The bottom end of the movable frame is slidably connected to the inside of the guide groove. One end of the traction member is fixedly connected to the jig platform, and the other end is fixedly connected to the outer end of the movable frame. The outer end of the limiting roller is rotatably connected to the fixed frame.

[0008] Furthermore, the limiting roller is hollow and is provided with a film-tearing component inside. The film-tearing component includes a driving roller. A film-feeding groove is provided at the outer end of the limiting roller. An adhesive is provided on the driving roller for sticking the protective film. A driving component is provided on the driving roller. The driving component is used to rotate the driving roller during the sliding of the blocking roller, thereby synchronously removing the film during the process of attaching the polarizer to the display.

[0009] Furthermore, a transmission shaft is rotatably connected to a side end of the fixing frame, and one end of the transmission shaft movably passes through the interior of the limiting roller and is fixedly connected to the driving roller.

[0010] Furthermore, the driving component includes a fixed shaft and a pulling wire, one end of the pulling wire is fixedly connected to the movable frame through the fixed shaft, and the other end is fixedly wound around the transmission shaft with multiple turns, and a spring roll is sleeved on the transmission shaft.

[0014] In the above technical solution, the polarizer laminating integrated jig provided by the present invention has the beneficial effects of:

[0015] By placing the blocking roller at the tail of the polarizer and the limiting roller at the head of the polarizer, the purpose of clamping is achieved. When attaching, the front end will first fit with the display. As the fixture platform moves, the pressing roller will eventually attach the polarizer to the display little by little, achieving attachment area by area and reducing the generation of bubbles. Not only that, when the polarizer is attached area by area, the traction part and drive shaft can also be used to synchronously tear off the protective film and reel it up, thereby shortening the time that the attachment surface of the polarizer is exposed to the outside air and reducing the risk of dust adhesion.

[0030] To make the purpose, technical solutions, and advantages of the embodiments of the present disclosure more clear, the technical solutions of the embodiments of the present disclosure will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, not all of the embodiments. Based on the described embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0031] Example 1, please refer to Figure 1-5 A polarizer laminating integrated jig includes an operating platform 1, a jig platform 2 is slidably provided on the top of the operating platform 1, a rolling component 3 is provided on the top of the operating platform 1, and the rolling component 3 includes a pressing roller 31. A driving source 4 is provided on the side end of the jig platform 2, which is responsible for pushing the jig platform 2 to make the display and the polarizer tightly attached;

[0032] Specifically, the driving source 4 is a hydraulic cylinder, which is connected to the controller to make it slowly extend and retract. The pressing roller 31 is set on the support platform 34. A lifting cylinder 32 is set at the end of the pressing roller 31. The lifting cylinder 32 can control the pressing roller 31 to move up and down to the set position. The position is specifically the position where the pressing roller 31 lightly presses above the polarizer when the display and the polarizer are adsorbed, and the pressure is adjusted according to demand.

[0033] The operating platform 1 is provided with a guide rail, and the fixture platform 2 slides on the operating platform 1 through the guide rail.

[0034] A laminating component 5 is provided on the top of the operating platform 1. The laminating component 5 includes a turning platform 51 for adsorbing the polarizer. A hydraulic motor 9 is provided on the side of the turning platform 51. The output end of the hydraulic motor 9 is connected to a turning shaft. The turning shaft is fixedly connected to the inner wall of the turning platform 51. The turning platform 51 can be driven by hydraulic power to rotate, thereby achieving the purpose of turning the polarizer onto the display.

[0035] What is different from the prior art is that after the flipping table 51 is flipped, it is not in a horizontal position, but tilted downward at an angle of 15-45 degrees, that is, one end is downward and the other end is tilted. The tilt angle is preferably 30 degrees, so that the blocking roller 61 lifts the tail of the polarizer and moves toward the fixture platform 2, supporting the tail of the polarizer at all times.

[0036] An auxiliary attaching component 6 is provided on the flip table 51, and the auxiliary attaching component 6 includes a blocking roller 61 and a limiting roller 62 provided on the flip table 51. The blocking roller 61 is provided with a traction member 63. The blocking roller 61 follows the fixture platform 2 through the traction member 63 to slide steadily, thereby lifting the unattached area of ​​the polarizer in the air.

[0037] The interior of the flip table 51 is hollow and is connected to a negative pressure pump on the outside, so that the interior of the flip table 51 is in a negative pressure state. Initially, the front end of the polarizer can be adsorbed so that it is attached to the flip table 51 in a flat surface, and then fits and attaches to the front end of the display. After it is attached to the outer wall, the negative pressure pump is turned off.

[0038] Specifically, the blocking roller 61 is located at the tail of the polarizer, and the limiting roller 62 is located at the head of the polarizer (keeping a small distance from the end, and this small distance is the area that needs to be initially adsorbed), which serves the purpose of clamping. When attaching, the front end will first fit with the display, and then drive the hydraulic cylinder, which will push the jig platform 2 to move under the pressing roller 31. At this time, the pressing roller 31 squeezes the display and the polarizer. As the jig platform 2 moves, the pressing roller 31 will eventually attach the polarizer to the display little by little, realizing attachment area by area and reducing the generation of bubbles.

[0039] In an embodiment further provided by the present invention, a guide groove 64 is provided on the flipping table 51, and a movable frame 65 is rotatably provided on the outer end of the blocking roller 61, and the bottom end of the movable frame 65 is slidably connected to the inside of the guide groove 64, one end of the traction member 63 is fixedly connected to the jig platform 2, and the other end is fixedly connected to the outer end of the movable frame 65, the outer end of the limiting roller 62 is rotatably connected to the fixed frame 66, and a movable groove is also provided at the side end of the flipping table, and the fixed frame 66 is slidably connected to the inside of the movable groove, the inner wall of the movable groove is embedded with an elastic block, and the inner wall of the movable groove is also fixedly connected to a reset spring.

[0040] When the blocking roller 61 slides and gradually approaches the limiting roller 62, it will use pressure to squeeze the elastic block, so that the limiting roller 62 also starts to move and continues to drop the tail end of the polarizer.

[0041] By setting up the traction member 63, the driving force of the movement of the jig platform 2 can be cleverly utilized to make the movable frame 65 move synchronously, so that the blocking roller 61 can move synchronously during the attachment process, and can always drag the tail of the polarizer, effectively preventing it from falling and being adsorbed on the display in advance, resulting in wrinkles or bubbles.

[0042] Example 2, please refer to Figure 6-8 In an embodiment further provided by the present invention, the limiting roller 62 is hollow inside and a film-tearing component 7 is provided inside. The film-tearing component 7 includes a driving roller 71. A film-feeding groove 72 is provided at the outer end of the limiting roller 62. An adhesive 73 is connected to the driving roller 71 for sticking the protective film. A driving component 8 is provided on the driving roller 71. The driving component 8 is used to rotate the driving roller 71 during the sliding process of the blocking roller 61, thereby synchronously removing the film during the process of the polarizer being attached to the display.

[0043] Furthermore, the driving component 8 includes a fixed shaft 81 and a pulling wire 82. One end of the pulling wire 82 is fixedly connected to the movable frame 65 through the fixed shaft 81, and the other end is fixedly wound around the transmission shaft 84 with multiple turns. The transmission shaft 84 is provided with a spring coil 83.

[0044] A rectangular groove is also provided at the side end of the turning table, and the fixed shaft is slidably connected to the rectangular groove. Similar to the above-mentioned fixed frame, an elastic block is also embedded and connected in the rectangular groove. The two elastic blocks are made of the same material, and the outer ends are both chamfered to facilitate contraction. Similarly, a reset spring is also fixedly connected in the rectangular groove to help reset the fixed shaft.

[0045] Furthermore, a transmission shaft 84 is rotatably connected to a side end of the fixing frame 66 . One end of the transmission shaft 84 movably passes through the interior of the limiting roller 62 and is fixedly connected to the driving roller 71 .

[0046] Specifically, the adhesive member 73 may be a single-sided adhesive tape with strong glue applied on the surface, which may be applied periodically thereafter.

[0047] First, the protective film is bonded to the adhesive 73 and the protective film, and then the flip table 51 is rotated, and then the jig platform 2 is pushed, and the transmission shaft 84 is pulled to rotate by winding one end of the pulling wire 82, thereby driving the driving roller 71 to rotate. During the rotation of the driving roller 71, the adhesive 73 is passed through, slowly tearing off the protective film of the polarizer, and the film is synchronously wound, thereby reducing the exposure time of the polarizer and reducing the risk of dust adhering between the display screen and the polarizer.

[0048] The protective film is torn off before the polarizer. At this time, when the blocking roller 61 contacts the limiting roller 62, it uses pressure to squeeze the elastic block, so that the limiting roller 62 and the fixed shaft 81 also start to move synchronously, and continue to drop the tail end of the polarizer.

[0049] Subsequently, the protective film is first pulled out, and the jig platform 2 is retracted by the hydraulic cylinder. Under the action of the spring coil 83, the transmission shaft 84 is rotated in the opposite direction, so that the adhesive member 73 returns to the initial position.

[0050] Example 3, please refer to Figure 9 , Example 3 is different from Example 2 in that the bonding member 73 includes a pair of electrostatic rollers 731 , a support block 734 is fixedly connected to the driving roller 71 , and the electrostatic roller 731 is rotatably connected to the side end of the support block 734 .

[0051] A toggle rod 733 is fixedly connected to the electrostatic roller 731, and the toggle rod 733 is located at the end of the electrostatic roller 731. The electrostatic roller 731 can rotate on the support block 734. A push rod 736 is provided on the top of the toggle rod 733. A slide groove is provided on the top of the limiting roller 62. The push rod 736 is slidably connected to the inside of the slide groove. A pressure spring 735 is fixedly connected between the push rod 736 and the limiting roller 62.

[0052] Initially, the top rod 736 can be pressed to rotate the toggle rod 733 downward, and the electrostatic roller 731 below starts to rotate, so that the protective film can enter between the pair of electrostatic rollers 731. Then the toggle rod 733 is released, and the friction force on the protective film is large enough through the squeezing of the pair of electrostatic rollers 731, so that the film can be torn off.

[0053] Since the protective film is a plastic film, the electrostatic rollers 731 roll the protective film to the inside through electrostatic adsorption force, and then there is a strong adhesion force between the two, so that the protective film can be torn off from the polarizer during the rotation of the driving shaft.

[0054] By subsequently pressing the top rod 736, the protective film can be pulled out completely, thrown away, and then continued to be used.

[0055] Optionally, the electrostatic roller 731 is cam-shaped and made of flexible material, such as a rubber coating. The electrostatic roller 731 is wrapped with an elastic material 732, and the toggle rod 733 extends into the elastic material 732. When the outside world needs to pull the protective film of the electrostatic roller, the elastic material 732 is squeezed, thereby generating a large positive pressure, thereby generating a large friction force, which can effectively prevent the protective film from being pulled out when the protective film is rolled up.

[0056] When the protective film needs to be pulled out, there is no need to press the toggle lever 733, and it can be directly pulled out with a little force.

[0057] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims.
