Description

Technical Field

[0001] This utility model relates to the field of polarizer processing, and in particular to a polarizer bonding equipment. Background Technology

[0002] Polarizing films are the core optical components of displays. They selectively transmit light with specific polarization directions, coordinating with the twisting of liquid crystal molecules to control brightness. Therefore, the bonding quality of polarizing films directly affects display contrast, viewing angle, and color accuracy. Currently, manual bonding of polarizing films suffers from problems such as dust easily falling onto the bonding surface and blistering. This forces workers to remove the polarizing films and repeat the bonding process, significantly reducing production efficiency.

Detailed Implementation

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0024] Please see Figures 1-3 The present invention provides a polarizer bonding device, including a rectangular plate-shaped base 1, with four supporting columns 2 at the four corners of its lower end face, and a clamping mechanism 3 for fixing and placing a substrate on the base 1.

[0025] In a preferred embodiment, the clamping mechanism 3 includes a placement groove 31 formed on the top surface of the base 1, which is used to place the substrate to which the polarizer is to be attached. Two strip-shaped through grooves 32 are symmetrically formed at the bottom of the placement groove 31. A clamping groove 33 is formed on the bottom surface of the base 1. The clamping groove 33 and the two strip-shaped through grooves 32 are collinear in the vertical direction and connected. A clamping screw 34 is rotatably connected inside the clamping groove 33. The clamping screw 34 has symmetrically arranged positive and negative threads, and two moving blocks 35 are fitted onto it through threaded engagement. The two moving blocks 35 can move towards or relative to each other. One end of the clamping screw 34 passes through the base 1 and is fixedly connected to a handle 36. A connecting rod is fixedly connected to each of the two moving blocks 35. The two connecting rods pass through the two strip-shaped through grooves 32 and into the placement groove 31, where they are fixedly connected to clamping rods 37. Rotating the handle 36 causes the clamping screw 34 to rotate, which in turn causes the moving block 35 and the clamping rod 37 above it to move towards or relative to each other. This clamps or releases the substrate placed in the placement groove 31, keeping the substrate in a fixed position during the bonding process. Preferably, a rubber layer can be added to the contact surface between the clamping rod 37 and the substrate to increase friction and effectively protect the edges of the substrate.

[0026] After the substrate is fixed in place, dust removal and bonding operations can be performed. An upper moving groove 11 and a lower moving groove 12 are symmetrically formed on the front and rear sides of the base 1. An upper moving screw 4 is rotatably connected to the upper moving groove 11, and a lower moving screw 5 is rotatably connected to the lower moving groove 12. A first motor 6 and a second motor 7 are mounted on the base 1. The first motor 6 and the second motor 7 are conventional motors capable of forward and reverse rotation. One of the upper moving screws 4 passes through the base 1 and is connected to the output end of the first motor 6, and one of the lower moving screws 5 passes through the base 1 and is connected to the output end of the second motor 7. Both upper moving screws 4 are connected to the same dust removal mechanism 8, and both lower moving screws 5 are connected to the same pressing mechanism 9. Starting the first motor 6 or the second motor 7 causes the upper moving screw 4 or the lower moving screw 5 to rotate, which in turn moves the dust removal mechanism 8 or the pressing mechanism 9 left and right. The dust removal mechanism 8 is used to remove dust from the substrate, and the pressing mechanism 9 is used to bond the polarizer to the substrate. It should be noted that the upper moving groove 11 and the lower moving groove 12 are offset in the vertical direction to ensure that the dust removal mechanism 8 and the pressing mechanism 9 do not come into contact during operation.

[0027] In the preferred embodiment, please refer to Figure 4 Referring to the dust removal mechanism 8, it includes two first moving rods 81, which are threadedly fitted onto two lower moving lead screws 5. Each first moving rod 81 is rotatably connected to a rotating shaft 82. A rotating block 84 is fixedly connected to the end of the rotating shaft 82 furthest from the first moving rod 81. A third motor 83 is fixedly mounted on one of the first moving rods 81. The output end of the third motor 83 passes through the first moving rod 81 and is connected to the rotating shaft 82 for transmission. The third motor 83 is a conventional servo motor, designed to rotate 180° and then stop, waiting for the next control to restart. A dust blowing assembly 85, a locking assembly 86, and a dust sticking assembly 87 are arranged between the two rotating blocks 84. The locking assembly 86 assists in storing the dust sticking assembly 87. During dust removal, the third motor 83 drives the two rotating blocks 84 to rotate, thereby quickly switching between the dust blowing assembly 85 and the dust sticking assembly 87 to work downwards towards the substrate, meeting different dust removal needs and improving dust removal efficiency.

[0028] In one implementation, the dust blowing assembly 85 includes an air compressor 851 and an air knife 852. Both the air compressor and air knife used in this device are existing technologies, and will only be briefly described here. The air compressor 851 is fixedly mounted on one of the rotating blocks 84, and both ends of the air knife 852 are fixedly connected to the two rotating blocks 84 respectively. The output end of the air compressor 851 is connected to the air inlet end of the air knife 852 through a pipe. When performing dust removal using the dust blowing assembly 85, the air knife 852 is first positioned vertically downwards, directly facing the clamping mechanism 3. Air is drawn into the air compressor 851, which compresses the air and inputs it into the air knife 852. Finally, the air is forcefully blown out from the outlet of the air knife 852, removing dust from the substrate surface during its left-right movement.

[0029] After the previous dust removal process, since stubborn dust may still remain on the substrate surface, a secondary dust removal is required. This necessitates switching to the adhesive component 87 to perform deep dust removal on the substrate using an adhesive method. The adhesive component 87 includes an adhesive roller 871, which can be fitted with a disposable adhesive paper. After the dust removal work is completed, the paper can be peeled off and replaced. Lifting blocks 872 are rotatably connected to both ends of the adhesive roller 871. Each of the two rotating blocks 84 has a vertically oriented lifting groove 841 on its bottom surface. The two lifting blocks 872 can be slidably embedded in the lifting grooves 841. A lifting spring 873 is fixedly connected between the lifting blocks 872 and the bottom of the lifting grooves 841. Under the elastic action of the lifting spring 873, the adhesive roller 871 can always remain in contact with the top surface of the base 1 and roll left and right to stick the dust on the substrate.

[0030] To facilitate quick and easy switching between the dust blowing assembly 85 and the dust sticking assembly 87, a snap-fit ​​assembly 86 is provided to retract the dust sticking assembly 87 upwards, preventing it from contacting the base 1. The snap-fit ​​assembly 86 includes a movable rod 861 and a fixed rod 862. Each of the two rotating blocks 84 has a first through slot communicating with the lifting groove 841 on its opposite end face. The two ends of the movable rod 861 pass through the two through slots and are fixedly connected to the two lifting blocks 872. A lower snap-fit ​​block 863 is fixedly installed on the movable rod 861. The two ends of the fixed rod 862 are fixedly connected to the two rotating blocks 84. An upper snap-fit ​​block 864 is fixedly installed on the fixed rod 862. The shapes of the upper snap-fit ​​block 864 and the lower snap-fit ​​block 863 are as shown in the figure, with their opposite ends hooked together, meaning the upper snap-fit ​​block 864 and the lower snap-fit ​​block 863 can be interlocked and locked together. In a preferred embodiment, a spring groove for mounting the upper snap-fit ​​block 864 is provided at the center of the fixing rod 862. A snap-fit ​​spring 865 is fixedly connected to the bottom of the spring groove, and the other end of the snap-fit ​​spring 865 is fixedly connected to the upper snap-fit ​​block 864. Two connecting blocks are fixedly provided on both sides of the spring groove on the fixing rod 862. The front and rear sides of the upper snap-fit ​​block 864 are rotatably connected to the two connecting blocks through shafts. Under normal conditions, the snap-fit ​​spring 865 applies a rightward lateral force to the upper snap-fit ​​block 864. When the worker pulls the lower snap-fit ​​block 863 upward, when it contacts the upper snap-fit ​​block 864, the upper snap-fit ​​block 864 rotates slightly around the shaft, squeezing the snap-fit ​​spring 865 to retract. The lower snap-fit ​​block 863 continues to move upward. When its end passes the end of the upper snap-fit ​​block 864, the snap-fit ​​spring 865 returns to its original position, causing the lower snap-fit ​​block 863 and the upper snap-fit ​​block 864 to engage, allowing the sticky roller 871 to approach the snap-fit ​​assembly 86 for fixed storage.

[0031] After dust removal is completed, the polarizer and substrate need to be bonded together using the pressing mechanism 9. Please refer to... Figure 5Referring to the pressing mechanism 9, it includes two second moving rods 91 and a pressing roller 94 disposed between the two second moving rods 91. The two second moving rods 91 are threadedly fitted onto two upper moving lead screws 4. Each of the two second moving rods 91 has an adjustment groove 92 formed in the vertical direction. Each of the opposite end faces of the two second moving rods 91 has a second through groove communicating with the adjustment groove 92. Adjusting blocks 93 are rotatably connected to both ends of the pressing roller 94. The ends of the two adjusting blocks 93 away from the pressing roller 94 pass through the two second through grooves and are movably disposed in the two adjustment grooves 92 by a fine-tuning component. The fine-tuning assembly includes a gear groove 95 and a fine-tuning shaft 98 disposed above the adjustment groove 92. The gear groove 95 communicates with the adjustment groove 92 through a through hole. A fine-tuning screw 96 is vertically disposed within the adjustment groove 92. The end of the adjustment block 93 furthest from the pressing roller 94 is threadedly fitted onto the fine-tuning screw 96. One end of the fine-tuning screw 96 is rotatably connected to the bottom wall of the adjustment groove 92, and the other end of the fine-tuning screw 96 is rotatably connected to the through hole and passes through the through hole into the gear groove 95, where a vertical bevel gear 97 is fixedly connected. Both ends of the fine-tuning shaft 98 are rotatably connected to two second moving rods 91, and one end completely penetrates one of the second moving rods 91 and is fixedly connected to a knob 910. Two longitudinal bevel gears 99 are fixedly fitted onto the fine-tuning shaft 98, and the two longitudinal bevel gears 99 mesh with the two vertical bevel gears 97 and are respectively arranged in the two gear grooves 95.

[0032] In practical work, due to differences in substrate height, in order to ensure that no air bubbles are generated during the bonding process and to avoid bonding failure or product damage caused by insufficient or excessive pressure, it is necessary to adjust the height of the pressing roller 94. With the above structure, during the bonding operation, turning the knob 910 causes the fine-tuning shaft 98 to drive the two longitudinal bevel gears 99 to rotate. The longitudinal bevel gears 99 mesh and drive the vertical bevel gear 97 to rotate, thereby driving the fine-tuning screw 96 to rotate. This allows the adjusting block 93 to move up and down along the fine-tuning screw 96, thereby adjusting the height of the pressing roller 94.

[0033] The method of using this utility model is as follows: Place the substrate to be coated with polarizing film into the placement slot 31, rotate the handle 36 to clamp the left and right sides of the substrate with the clamping rod 37, start the third motor 83, switch the dust blowing assembly 85 downward alignment, and then start the second motor 7 to drive the dust blowing assembly 85 (air compressor 851 and air knife 852) to move laterally along the base 1. The strong airflow blows away the dust on the surface of the substrate. When the dust blowing assembly 85 moves to the right end, turn off the second motor 7. Start the third motor 83 to switch the adhesive assembly 87 downward alignment, and push the upper locking block 864 upward to release the lower locking block 863, so that the adhesive roller 871 presses down on the top surface of the base 1. Start the second motor 7 to reverse, and the adhesive roller 871 moves to the left on the base 1 to perform secondary dust removal on the upper surface of the substrate for stubborn dust. When the adhesive roller 871 returns to the initial position, the second motor 7 is turned off, and the lower locking block 863 is pulled upward to engage with the upper locking block 864. After the dust removal work is completed, the staff aligns the polarizer and places it on the substrate. According to the height of the substrate, the staff turns the knob 910 to adjust the pressing roller 94 to an appropriate height, and starts the first motor 6 to drive the pressing roller 94 to roll back and forth to bond the polarizer to the substrate. Since the pressing roller 94 is set to an appropriate height, the pressing force is optimal and can completely remove air bubbles on the bonding surface, thus completing the bonding work.
