Description

Technical Field

[0001] The present invention relates to the technical field of polarizer lamination, and particularly relates to an integrated fixture for polarizer lamination. Background Art

[0002] Polarizer lamination is a process of precisely laminating a polarizer to a screen panel. The polarizer is usually made of a thin film material with special optical properties, which 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, the polarizer is directly laminated onto the display, resulting in the easy generation of bubbles during the rolling process of the roller. Moreover, during the polarizer lamination process, the protective film needs to be torn off in advance and then laminated. If this process is too long, the protective film will be torn off too early, which is also likely to cause dust adsorption and increase the risk of dust adhesion between the polarizer and the display. Summary of the Invention

[0004] The purpose of the present invention is to provide an integrated fixture for polarizer lamination to solve the above deficiencies in the prior art.

[0005] To achieve the above purpose, the present invention provides the following technical solutions:

[0006] An integrated fixture for polarizer lamination includes an operation platform. A fixture platform is slidably arranged on the top of the operation platform. A rolling component is arranged on the top of the operation platform. The rolling component includes a pressing roller. A driving source is arranged at the side end of the fixture platform, which is responsible for pushing the fixture platform to closely attach the display and the polarizer. A lamination component is arranged on the top of the operation platform. The lamination component includes a flipping table for adsorbing the polarizer. An auxiliary lamination component is arranged on the flipping table. The auxiliary lamination component includes a blocking roller and a limiting roller arranged on the flipping table. A traction member is arranged on the blocking roller. When the blocking roller steadily slides along with the fixture platform through the traction member, it lifts the non-laminated area of the polarizer in a suspended state.

[0007] Further, a guiding groove is formed on the flipping table. A moving frame is rotatably arranged at the outer end of the blocking roller. The bottom end of the moving frame is slidably connected to the inside of the guiding groove. One end of the traction member is fixedly connected to the fixture platform, and the other end is fixedly connected to the outer end of the moving frame. The outer end of the limiting roller is rotatably connected to a fixed frame.

[0008] Further, the inside of the limiting roller is hollow, and a film tearing component is arranged inside. The film tearing component includes a driving roller. An inlet film groove is formed at the outer end of the limiting roller. A bonding component is arranged on the driving roller for sticking the protective film. A driving component is arranged on the driving roller. The driving component is used for rotating the driving roller during the sliding process of the blocking roller, so as to synchronously remove the film during the process of attaching the polarizer to the display.

[0009] Further, a transmission shaft is rotatably connected to the side end of the fixing frame. One end of the transmission shaft movably penetrates into the inside of the limiting roller and is fixedly connected to the driving roller.

[0010] Further, the driving component includes a fixed shaft and a pulling wire. One end of the pulling wire is fixedly connected to the moving frame through the fixed shaft, and the other end is fixedly wound around the transmission shaft in multiple turns. A spring winding is sleeved on the transmission shaft.

[0011] Further, the pressing roller is arranged on the support table. A lifting air cylinder is arranged at the end of the pressing roller. The pressing roller can be controlled to move to a set position through the lifting air cylinder.

[0012] Further, the bonding component includes a pair of static rollers. A support block is fixedly connected to the driving roller. The static rollers are rotatably connected to the side end of the support block.

[0013] Further, a guiding slide rail is arranged on the operation platform. The jig platform slides on the operation platform through the guiding slide rail.

[0014] In the above technical solution, the beneficial effects of the polarizer attachment integrated jig provided by the present invention are as follows:

[0015] By making the blocking roller located at the tail of the polarizer and the limiting roller located at the head of the polarizer, the purpose of clamping is achieved. When attaching, the front part will first be attached to the display. As the jig platform moves, finally the pressing roller will attach the polarizer to the display little by little, realizing area-by-area attachment and reducing the generation of bubbles. Moreover, when the polarizer is attached area by area, the protective film can be synchronously torn off and wound up by using the traction component and the transmission shaft, so as to shorten the exposure time of the attachment surface of the polarizer to the outside air, and further reduce the risk of dust adhesion.

[0030] To make the objectives, technical solutions, and advantages of the embodiments of the present disclosure clearer, the following will clearly and completely describe the technical solutions of the embodiments of the present disclosure with reference to the accompanying drawings of the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, rather than all of the embodiments. Based on the described embodiments of the present disclosure, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present disclosure.

[0031] Example 1, please refer to Figures 1-5 , a polarizer laminating integrated fixture, including an operation platform 1, a fixture platform 2 is slidably arranged on the top of the operation platform 1, a rolling component 3 is arranged on the top of the operation platform 1, the rolling component 3 includes a pressing roller 31, and a driving source 4 is arranged at the side end of the fixture platform 2, which is responsible for pushing the fixture platform 2 to closely attach the display and the polarizer;

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

[0033] A guiding slide rail is arranged on the operation platform 1, and the fixture platform 2 slides on the operation platform 1 through the guiding slide rail.

[0034] A laminating component 5 is arranged on the top of the operation platform 1. The laminating component 5 includes a flipping table 51 for adsorbing the polarizer. A hydraulic motor 9 is arranged at the side end of the flipping table 51. The output end of the hydraulic motor 9 is connected to a rotating shaft, and the rotating shaft is fixedly connected to the inner wall of the flipping table 51. The flipping table 51 can be driven to rotate by hydraulic power to achieve the purpose of flipping the polarizer onto the display;

[0035] Different from the prior art, after the flipping table 51 flips, it is not in a horizontal position, but is inclined downward at an angle of 15 - 45 degrees, that is, one end is downward and the other end is upturned. The inclination angle is preferably 30 degrees, so that the blocking roller 61 lifts the tail of the polarizer and moves along with the movement towards the fixture platform 2, constantly supporting the tail of the polarizer.

[0036] An auxiliary laminating component 6 is arranged on the flipping table 51. The auxiliary laminating component 6 includes a blocking roller 61 and a limiting roller 62 arranged on the flipping table 51. A traction member 63 is arranged on the blocking roller 61. When the blocking roller 61 steadily slides along with the fixture platform 2 through the traction member 63, it plays a role in suspending and lifting the non-laminated area of the polarizer.

[0037] The inside of the turning table 51 is hollow, and a negative pressure pump is externally connected, making the inside of the turning table 51 in a negative pressure state. Initially, the front end of the polarizer can be adsorbed, making it flatly attached to the turning table 51, and then fittingly attached to the front end of the display. After attaching to the outer wall, the negative pressure pump is then 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 adsorbed initially), serving the purpose of clamping. During the attachment process, the front part will first fit with the display, and then the hydraulic cylinder is driven. The hydraulic cylinder will push the jig platform 2 to move under the pressing roller 31. At this time, the pressing roller 31 presses the display and the polarizer. As the jig platform 2 moves, finally the pressing roller 31 gradually attaches the polarizer to the display little by little, achieving attachment zone by zone and reducing the generation of bubbles.

[0039] In the embodiment further provided by the present invention, a guiding groove 64 is formed on the turning table 51. A moving frame 65 is rotatably arranged at the outer end of the blocking roller 61. The bottom end of the moving frame 65 is slidably connected to the inside of the guiding 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 moving frame 65. The outer end of the limiting roller 62 is rotatably connected to a fixed frame 66. An activity groove is also formed at the side end of the turning table. The fixed frame 66 is slidably connected to the inside of the activity groove. An elastic block is embedded in the inner wall of the activity groove, and a return spring is also fixedly connected to the inner wall of the activity groove.

[0040] When the blocking roller 61 slides and gradually approaches the limiting roller 62, the elastic block will be squeezed by the pressure, causing the limiting roller 62 to also start moving and continue to let the tail end of the polarizer drop.

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

[0042] Example 2, please refer to Figures 6-8 , in the embodiment further provided by the present invention, the inside of the limiting roller 62 is hollow, and a film tearing member 7 is arranged inside. The film tearing member 7 includes a driving roller 71. An inlet film groove 72 is formed at the outer end of the limiting roller 62. A bonding member 73 is connected to the driving roller 71 for sticking to the protective film. A driving member 8 is arranged on the driving roller 71. The driving member 8 is used to make the driving roller 71 rotate during the sliding process of the blocking roller 61, so as to remove the film synchronously during the process of attaching the polarizer to the display.

[0043] Further, 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 moving frame 65 after passing through the fixed shaft 81, and the other end is fixedly wound around the transmission shaft 84 in multiple turns. A spring roll 83 is sleeved on the transmission shaft 84.

[0044] A rectangular groove is also formed at the side end of the flipping table. The fixed shaft is slidably connected in the rectangular groove. Similar to the above-mentioned fixed frame, elastic blocks are also embedded and connected in the rectangular groove. The two elastic blocks are made of the same material, and chamfers are provided at the outer ends for easy contraction. Similarly, a return spring is also fixedly connected in the rectangular groove to help the fixed shaft reset.

[0045] Further, a transmission shaft 84 is rotatably connected to the side end of the fixed frame 66. One end of the transmission shaft 84 movably penetrates into the interior of the limiting roller 62 and is fixedly connected to the driving roller 71.

[0046] Specifically, the bonding member 73 can be a single-sided adhesive tape with strong glue applied on the surface, and it can be applied regularly later.

[0047] First, bond the protective film to the bonding member 73 and the protective film. Then rotate the flipping table 51. Next, push the jig platform 2. By winding up one end of the pulling wire 82, the transmission shaft 84 is pulled to rotate, thereby driving the driving roller 71 to rotate. During the rotation of the driving roller 71, the protective film of the polarizer is slowly torn off through the bonding member 73, and the film is synchronously wound up, thereby reducing the time for the polarizer to be exposed and reducing the risk of dust adhering between the display screen and the polarizer.

[0048] When the protective film is torn off earlier than the polarizer, when the blocking roller 61 abuts against the limiting roller 62, the elastic block is squeezed by the pressure, so that the limiting roller 62 and the fixed shaft 81 also start to move synchronously, and the tail end of the polarizer continues to fall down.

[0049] Subsequently, first pull out the protective film, then retract the jig platform 2 through the hydraulic cylinder. Under the action of the spring roll 83, the transmission shaft 84 is rotated in the reverse direction, and the bonding member 73 returns to the initial position.

[0050] Example 3, please refer to Figure 9 , the difference between Example 3 and Example 2 is 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 push 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 the polarizer during the rotation of the driving shaft.

[0054] By subsequently pressing the top rod 736, the protective film can be completely pulled out, 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 electrostatic roller needs to pull the protective film, 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 the protective film can be directly pulled out with a little force.

[0057] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that 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 above 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.
