Description

Technical Field

[0001] The present invention relates to the technical field of polarizer production, and in particular to a polarizer attaching device and an attaching method thereof. Background Art

[0002] The full name of polarizer is polarizing film. The imaging of liquid crystal display must rely on polarized light. All liquid crystals have two polarizing films in the front and back that are tightly attached to the liquid crystal glass module to form a liquid crystal film. If any polarizer is missing, the liquid crystal film cannot display the image. Therefore, during production, the polarizer needs to be attached to the liquid crystal glass module through an attaching device.

[0003] For example, in the Chinese patent application number 202410025132.3, a polarizer attaching device is provided. By cooperating with a swing assembly consisting of a control rod, a displacement portion and an adjustment portion and a support assembly, the amplitude of the reciprocating movement of the vertical plate in the horizontal direction can be conveniently adjusted, so that polarizers of different lengths can be attached. By cooperating with the telescopic assembly and the pressure adjustment assembly, the squeezing force of the lamination roller on the polarizer can be conveniently adjusted, thereby effectively improving the attachment effect.

[0004] During use, this type of laminating equipment uses a pressing roller to press the polarizer. However, this single pressing method cannot effectively handle the edges or local areas, resulting in insufficient bonding strength and affecting the use effect.

A spring 2 664 is sleeved on the outer surface of the cross bar 661, and the two ends of the spring 2 664 are respectively connected to the rectangular frame 60 and the arc block 1 662.

[0051] When in use, the glass module is placed in the placement box 2, and a fixing device can be installed in the placement box 2 to fix the glass module, and the vacuum suction head 3 is connected to the external pump body to generate suction at the outlet of the vacuum suction head 3, and the polarizer is sucked by the vacuum suction head 3, and the vacuum suction head 3 and the polarizer are driven downward by the cylinder to make the polarizer adhere to the glass module coated with glue. This is the existing technology, so it will not be described in detail here.

[0052] Considering that in the prior art, the polarizer is pressed by an elastic pressing roller 56, but this single pressing method cannot effectively process the edge or local area, resulting in insufficient bonding strength and affecting the use effect, the following improvements are now made:

[0053] When attaching the polarizer to the glass module coated with glue, the vacuum suction head 3 is driven upward by the cylinder, and the mounting frame 4 is driven to move by the cylinder, so that the pressing mechanism 5 is moved to the top of the placement box 2, so that the elastic pressing roller 56 is in contact with the polarizer, and the sliding rod 57 is slidably connected with the cross plate 54 and the elastic force of the spring 58, so that the elastic pressing roller 56 can be tightly attached to the polarizer to improve the rolling effect. In the early stage, the fixed block 52 is driven to move by the electric push rod 41, and the fixed block 52 drives the mounting plate 51, the limit rod 53, the cross plate 54, the sliding rod 57, the L-shaped block 55 and the elastic pressing roller 56 to move together, so that the elastic pressing roller 56 moves on the surface of the polarizer to perform the pressing operation and firmly attach the polarizer to the glass module.

[0054] When the one-way pressing operation is completed, the mounting plate 51 will move from the left side to the right side of the mounting frame 4, and will be connected to the mounting plate 51 through the impact rod 61, and the impact rod 61 will correspond to the position of the force block 65. When the impact rod 61 moves to contact the right force block 65, it will drive the right force block 65 and the extrusion rod 1 64 to move to the right, and squeeze the right spring 3 67 until the arc block 2 663 moves to contact the arc block 1 662. Since the cross bar 661 slides on the inner wall of the rectangular frame 60, when the arc block 2 663 contacts the arc block 1 662, it will drive the arc block 1 662 and the piston plate 2 611 to move to both sides, squeezing the spring 2 664 until The arc block 2 663 is stuck in the arc groove provided on the arc block 1 662, locking the arc block 2 663 and the force block 65. At this time, the extrusion rod 1 64 will drive the piston plate 1 63 to move rightward in the liquid storage cylinder 1 62, squeezing the fluid in the liquid storage cylinder 1 62, so that the fluid enters one of the liquid storage cylinders 2 610 through the hose 1 68. Since the piston plate 2 611 slides in the liquid storage cylinder 2 610, when the piston plate 2 611 is impacted by the fluid, it will drive the piston plate 2 611 and the push rod 612 to move toward the middle together, and the push rod 612 will drive the moving bar 614 to move toward the middle, so that the vertical rod 615 moves to the same horizontal line as the arc block 3 617.

[0055] When the elastic pressure roller 56 returns, since the vertical rod 615 and the arc block three 617 are located on the same horizontal line, when the arc block three 617 moves to contact the vertical rod 615, downward pressure will be generated on the arc block three 617, and the arc block three 617 is connected to the lifting frame 616. The arc block three 617 will drive the lifting frame 616, the horizontal plate 54, the connecting rod 6122, and the pressing strip 6123 to move downward to roll the polarizer. The lifting frame 616 will also drive the telescopic rod 6120 to move downward in the fixed cylinder 618 to squeeze the spring five 6121. Since there are multiple vertical rods 615, the arc block three 617 intermittently contacts the vertical rod 615, so that the pressing strip 6123 intermittently contacts the polarizer for point pressing. In this way, the elastic pressure roller 56 squeezes the polarizer by rolling when it moves in a single direction, and can intermittently perform point pressing on the polarizer when it returns.

[0056] A further benefit of adopting the above method is that the polarizer is adhered to the glass module by intermittently using lamination and point pressing. Rolling can provide uniform pressure distribution to ensure full contact between the polarizer and the glass, thereby reducing the formation of bubbles and voids and enhancing the overall bonding strength, while point pressing can apply pressure in a targeted manner, which can effectively process edges or local areas and ensure the bonding quality of each key point. Moreover, through this intermittent adjustment of the lamination method, the temperature of the elastic pressure roller 56 can be avoided from rising due to long-term rolling, thereby preventing excessive temperature from affecting the entire material and helping to protect the performance of the material.

[0057] It should be noted that when the moving bar 614 moves toward the middle, it will also drive the push rod 612 and the piston plate 2 611 on the other side to slide in the liquid storage cylinder 2 610, so that the fluid in the liquid storage cylinder 2 610 on the other side enters the liquid storage cylinder 1 62 on the left through the hose 1 68, and the piston plate 1 63 moves in the liquid storage cylinder 1 62 toward the rectangular frame 60, so that the force block 65 and the arc block 2 663 on the left are separated from the arc block 1 662. In this way, when the elastic pressure roller 56 returns, it will contact and squeeze the force block 65 on the left, thereby driving the vertical rod 615 and the moving bar 614 to reset, so that the vertical rod 615 and the arc block 3 617 are not on the same horizontal line, so that the intermittent adjustment pressing method can be completed, and the fluid can be one of water or oil.

[0058] Example 2, refer to Figure 1-Figure 12 A polarizer attachment device includes a frame 1, a placement box 2 is fixed on the frame 1, a vacuum suction head 3 is arranged above the placement box 2, a cylinder for driving the vacuum suction head 3 to move up and down is arranged on the frame 1, a mounting frame 4 is arranged inside the frame 1, a cylinder for driving the mounting frame 4 to move is installed on the frame 1, an electric push rod 41 is fixed on the mounting frame 4, and also includes:

[0059] A pressing mechanism 5 disposed on the mounting frame 4, the pressing mechanism 5 is used for pressing the polarizer;

[0060] A point pressing mechanism 6 mounted on the mounting frame 4, the point pressing mechanism 6 is used to perform point pressing on the polarizer;

[0061] An adjusting mechanism 7 is arranged on the pressing mechanism 5, and the adjusting mechanism 7 is used to increase the point pressing range of the point pressing mechanism 6;

[0062] The pressing mechanism 8 is installed on the pressing mechanism 5 , and the pressing mechanism 8 is used to improve the hardness of the pressing mechanism 5 .

[0063] Furthermore, the adjustment mechanism 7 includes a hose 71 connected to the fixed cylinder 618, an air cushion 72 is fixed in the pressing strip 6123, the other end of the hose 71 away from the fixed cylinder 618 is connected to the air cushion 72, a rectangular strip 73 is fixed to the outer surface of the air cushion 72, a moving rod 74 is fixed to the side of the rectangular strip 73 away from the air cushion 72, the moving rod 74 is slidably connected to the pressing strip 6123, the outer surface of the moving rod 74 is sleeved with a spring 6 70, the two ends of the spring 6 70 are respectively fixedly connected to the rectangular strip 73 and the pressing strip 6123, an auxiliary strip 75 is fixed to the end of the moving rod 74 away from the rectangular strip 73, and elastic pads are fixed to the bottom of the pressing strip 6123 and the auxiliary strip 75.

[0064] Considering that there are multiple vertical rods 615, the pressing strip 6123 cannot completely cover the surface of the polarizer. If the area of ​​the pressing strip 6123 is too large, it may affect the pressing operation of the elastic pressing roller 56. The following improvements are made:

[0065] The second hose 71 is connected to the fixed cylinder 618. When the lifting frame 616 and the arc block 3 617 are intermittently pressed down due to the squeezing of the vertical rod 615, the telescopic rod 6120 is also driven to intermittently move downward in the fixed cylinder 618. The telescopic rod 6120 drives the piston plate 3 619 to move up and down in the fixed cylinder 618, squeezing the gas in the fixed cylinder 618, so that the gas enters the air cushion 72 through the second hose 71, and the air cushion 72 expands, thereby driving the rectangular strip 73 and the moving rod 74 to move to both sides. The moving rod 74 moves to squeeze the spring 6 70, and the moving rod 74 drives the auxiliary strip 75 to move to both sides, so that the auxiliary strip 75 moves out of the pressing strip 6123. In this way, when point pressing is performed, the point pressing area can be increased. When point pressing is performed, it can be ensured that each area can be point pressed to improve the attachment effect. When the pressing strip 6123 is not in contact with the polarizer, the elastic force of the moving rod 74 will move the auxiliary strip 75 into the pressing strip 6123, thereby reducing the occupied area and avoiding affecting the pressing operation of the elastic pressing roller 56.

[0066] It should be noted that elastic pads are fixed to the bottom of the pressing strip 6123 and the auxiliary strip 75. The elastic pads not only protect the polarizer during point pressing, but also when the auxiliary strip 75 is moved out of the pressing strip 6123, it can be placed in the same position as the pressing strip 6123, so that the auxiliary strip 75 can also have a point pressing effect.

[0068] A pressing mechanism 5 disposed on the mounting frame 4, the pressing mechanism 5 is used for pressing the polarizer;

[0069] A point pressing mechanism 6 mounted on the mounting frame 4, the point pressing mechanism 6 is used to perform point pressing on the polarizer;

[0070] An adjusting mechanism 7 is arranged on the pressing mechanism 5, and the adjusting mechanism 7 is used to increase the point pressing range of the point pressing mechanism 6;

[0071] The pressing mechanism 8 is installed on the pressing mechanism 5 , and the pressing mechanism 8 is used to improve the hardness of the pressing mechanism 5 .

[0072] Furthermore, the extrusion mechanism 8 includes a rack 81 fixed to the top of one of the sliding rods 57, the outer surface of the rack 81 is meshed with a gear 82, a bidirectional screw rod 83 is fixed at the axis of the gear 82, a support bar 84 is fixed to the top of the cross plate 54, both ends of the bidirectional screw rod 83 are rotatably connected to the support bar 84, the outer surface of the bidirectional screw rod 83 is symmetrically threaded with a thread block 85, a fixing rod 86 is fixed to the top of the thread block 85, the fixing rod 86 is slidably connected to the support bar 84, and an extrusion bar 87 is fixed to the end of the fixing rod 86 away from the thread block 85.

[0073] Since the rack 81 is connected to the slide bar 57, when the lifting frame 616 and the arc block 3 617 are intermittently pressed down due to the squeezing of the vertical rod 615, the elastic pressure roller 56 will first contact the polarizer. Since the slide bar 57 is slidably connected to the horizontal plate 54, when the elastic pressure roller 56 contacts the polarizer, it will drive the slide bar 57 to slide upward, thereby driving the rack 81 to move upward. When the rack 81 moves, it drives the gear 82 to rotate. The gear 82 drives the bidirectional screw rod 83 to rotate, and is slidably connected to the support bar 84 through the fixed rod 86 for limiting. Therefore, it will drive the fixed rod 86 and the squeezing bar 87 move toward the middle, and when the rack 81 moves downward, it will drive the fixed rod 86 and the squeezing bar 87 to move to both sides. Therefore, during intermittent point pressing, it will drive the squeezing bar 87 to move intermittently toward the middle to squeeze the elastic pressing roller 56. Since the elastic pressing roller 56 is elastic, the part where the elastic pressing roller 56 contacts the polarizer is squeezed. In this way, the hardness of the elastic pressing roller 56 can be appropriately improved, and the applied pressure can be more effectively transmitted to the material, thereby further enhancing the point pressing effect and improving production efficiency.
