Description

Technical Field

[0001] The invention relates to the technical field of polarizing plates, and in particular to a production device for polarizing plates used for liquid crystal display imaging. Background Art

[0002] A polarizer is an optical filter in which the transmittance of light is directly related to its polarization state. When a beam of natural light hits the polarizer, the polarizer will selectively allow linear polarized light in a specific direction to pass through, while light with a polarization direction perpendicular to it will be absorbed or reflected in other directions. This characteristic makes polarizers widely used in optical display, optical communication, photography and other fields.

[0003] At present, drying is a crucial step in the production of polarizers. If the drying is uneven or the humidity is unstable, the solvent will not evaporate completely, the surface flatness will decrease, and the adhesive layer will not be fully cured, which will seriously affect the quality of the polarizer.

[0004] Combining the above problems, we will find that it is difficult to avoid the above problems at the same time when using the existing polarizing film production equipment for liquid crystal display imaging on the market, and even if it can be solved, it needs to be solved with the cooperation of external tools, so it is impossible to achieve the desired effect.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0019] 1. After the polarizing light sheet body is trimmed and embossed, it enters the drying oven. By arranging a gas distribution unit in the drying oven, the hot air blown by the hot air blower can be evenly blown on the polarizing light sheet body to ensure the drying uniformity, avoid uneven drying from affecting the quality of the polarizing light sheet body. In the preheating area at the front stage, the humidity is maintained by the humidifying component to avoid problems such as local over-drying or over-wetting of the polarizing light sheet body, which helps the polarizing light sheet body to dry evenly and effectively improves the quality of the polarizing light sheet body.

[0039] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0040] Embodiment 1: Please refer to Figures 1 - 16 , the present invention provides a technical solution: A production device for a polarizing light sheet used in liquid crystal display imaging, including a feeding module 1, a drying module 11 and a material receiving module 4. The drying module 11 includes a plurality of drying boxes 2 and a plurality of sheet pulling boxes 3;

[0041] A deviation correction module and a sheet pulling module are rotatably arranged inside the sheet pulling box 3;

[0042] The feeding module 1 includes a trimming module, an embossing module, a storage module and a temporary winding module;

[0043] The material receiving module 4 includes a deviation correction module, a trimming module, a storage module and a winding module; among them, the trimming module, the embossing module, the storage module, the temporary winding module, the deviation correction module, the sheet pulling module and the winding module are all prior arts and will not be elaborated here.

[0044] A hot air blower 21 is fixedly installed on the top of the drying box 2. An air outlet 22 is fixedly connected to the bottom of the drying box 2. A fixing plate 23 is fixedly installed inside the drying box 2. An adjusting unit 7 is arranged on the surface of the fixing plate 23. A guide roller 24 is rotatably connected inside the adjusting unit 7. A polarizing light sheet body 5 is wound around the outer wall of the guide roller 24. An air distribution unit 6 and a humidifying unit 8 are arranged inside the drying box 2;

[0045] The air distribution unit 6 includes an air guide box 61 fixedly installed on the inner wall of the drying box 2. A compression groove 6101 is formed inside the air guide box 61. A dispersion assembly 62 is fixedly connected to the surface of the air guide box 61. The dispersion assembly 62 is communicated with the compression groove 6101.

[0046] Among them, the polarizing light sheet body 5 discharged by casting enters the embossing module after trimming by the trimming module. Embossing is to maintain roughness so that the polarizing light sheet body 5 is convenient to be on the guide roller 24. The embossed polarizing light sheet body 5 enters the drying box 2 through the storage module and the temporary winding module. During the drying process, it passes through the deviation correction module and the sheet pulling module to avoid the position deviation of the polarizing light sheet body 5 caused by excessive length. The dried polarizing light sheet body 5 enters the winding module through the deviation correction module, the trimming module and the storage module; In addition, several drying boxes 2 and several sheet pulling boxes 3 form three drying areas, namely the front preheating area composed of several drying boxes 2, the middle high-temperature drying area composed of several drying boxes 2, and the rear low-temperature drying area composed of several drying boxes 2. The low-temperature range is 30°C - 50°C, and the high-temperature range is 50°C - 85°C. The humidifying unit 8 is arranged in the drying boxes 2 in the front preheating area and the middle high-temperature drying area, and the humidifying amount in the middle high-temperature drying area is lower than that in the front preheating area. The humidifying unit 8 is not arranged in the rear low-temperature drying area. The drying box 2 is provided with an air supply pipe 6201 extending into the sheet pulling box 3 to keep the temperature inside the sheet pulling box 3 consistent with that inside the drying box 2 and avoid the influence of a large temperature difference on the quality of the polarizing light sheet body 5.

[0047] After the polarizing light sheet body 5 is trimmed and embossed, it enters the drying box 2. By arranging the air distribution unit 6 in the drying box 2, the hot air blown out by the hot air blower 21 can be evenly blown on the polarizing light sheet body 5 to ensure the drying uniformity and avoid affecting the quality of the polarizing light sheet body 5 due to uneven drying. In the front preheating area, the humidity is maintained through the humidifying component to avoid the problems of local over-drying or over-wetting of the polarizing light sheet body 5, which helps the polarizing light sheet body 5 to dry evenly and effectively improves the quality of the polarizing light sheet body 5.

[0048] As a further limitation of the air distribution unit 6 of the present invention, the dispersion assembly 62 includes an air supply pipe 6201 fixedly connected to the surface of the air guide box 61. The air supply pipe 6201 is communicated with the compression groove 6101. A first connecting pipe 6202 is fixedly communicated with the surface of the air supply pipe 6201. An air distribution pipe 6203 is slidably connected inside the first connecting pipe 6202. A first arc-shaped guide piece 6204 is fixedly installed on the inner wall of the air supply pipe 6201. One end of the inner wall of the air distribution pipe 6203 is fixedly installed with a spiral blade 6205. A spiral opening 6206 is formed on the surface of the air distribution pipe 6203. The hot air entering the air guide box 61 quickly enters the air supply pipe 6201 after being compressed by the compression groove 6101. The hot air passes through the air supply pipe 6201 and is guided by the first arc-shaped guide piece 6204. The hot air is shunted into a plurality of first connecting pipes 6202. The hot air is evenly dispersed in the drying box 2 through the first connecting pipe 6202 and the air distribution pipe 6203. Through the arrangement of the spiral blade 6205, when the hot air enters the air distribution pipe 6203, the air distribution pipe 6203 is rotated, and the hot air is dispersed and discharged from the air distribution pipe 6203 through the spiral opening 6206, so as to blow the other side of the polarizing plate body 5 that cannot be blown by the hot air blower 21, effectively ensuring the drying uniformity of the polarizing plate body 5 and ensuring the quality of the polarizing plate body 5.

[0049] The specific implementation mode of this embodiment is as follows: The polarizing plate body 5 discharged by casting enters the feeding module 1. The polarizing plate body 5 is trimmed by the trimming module, and the polarizing plate body 5 is embossed by the embossing module. The embossed polarizing plate body 5 enters the drying module 11 through the temporary winding module. When the polarizing plate body 5 passes through the drying box 2, through the deviation correction module and the pulling module, the polarizing plate body 5 can pass through the drying box 2 smoothly. In the drying box 2, the polarizing plate body 5 is dried by the hot air blower 21. During the drying process, part of the hot air blown out by the hot air blower 21 enters the air guide box 61. The hot air quickly enters the air supply pipe 6201 after being compressed by the compression groove 6101. After being guided by the first arc-shaped guide piece 6204 in the air supply pipe 6201, the hot air is shunted into a plurality of first connecting pipes 6202. The hot air is blown into the drying box 2 through the first connecting pipe 6202 and the air distribution pipe 6203, and the other side of the polarizing plate body 5 that cannot be blown by the hot air blower 21 is blown. When the hot air enters the air distribution pipe 6203 through the first connecting pipe 6202, the air distribution pipe 6203 is driven to rotate when the hot air passes through the spiral blade 6205, and by arranging the spiral opening 6206 on the surface of the air distribution pipe 6203, the air distribution pipe 6203 evenly disperses the hot air, so as to improve the drying uniformity of the polarizing plate body 5, thereby ensuring the quality of the polarizing plate body 5. The dried polarizing plate body 5 enters the material receiving module 4. After passing through the deviation correction module, the trimming module and the storage module, it is wound by the winding module.

[0051] As a further limitation of the adjusting unit 7 of the present invention, the adjusting unit 7 includes an upper bracket 71, the upper bracket 71 is slidably connected to the opposite sides of the two fixing plates 23, a bottom bracket 72 is fixedly installed on the inner wall of the drying box 2, a lower bracket 73 is arranged on the top of the bottom bracket 72, both the lower bracket 73 and the upper bracket 71 are rotatably connected to the air distribution pipe 6203, the guide roller 24 is rotatably installed at the bottom of the upper bracket 71 and the inner wall of the lower bracket 73, a hydraulic cylinder 74 is fixedly installed at the bottom of the drying box 2, the telescopic end of the hydraulic cylinder 74 extends into the drying box 2 and is slidably connected to the drying box 2, and a linkage assembly 75 is fixedly installed at the bottom of the upper bracket 71; by driving the upper bracket 71 to move through the hydraulic cylinder 74, the upper bracket 71 drives the guide roller 24 above the drying box 2 to move downward, and at the same time the upper bracket 71 makes the lower bracket 73 move upward through the linkage assembly 75, so that the guide roller 24 below the drying box 2 moves upward, and by adjusting the height of the guide roller 24, the function of adjusting the residence time of the polarizing light sheet main body 5 in the drying box 2 is achieved. Before drying the polarizing light sheet main body 5, if the thickness of the polarizing light sheet main body 5 is less than 5 microns, by adjusting the position of the guide roller 24, the distance between the upper guide roller 24 and the lower guide roller 24 is reduced, and at this time the polarizing light sheet main body 5 is wound around the surface of the guide roller 24 to reduce the time of the polarizing light sheet main body 5 in the drying box 2 and avoid the polarizing light sheet main body 5 becoming brittle due to over-drying. If the thickness of the polarizing light sheet main body 5 is greater than 5 microns, the distance between the upper guide roller 24 and the lower guide roller 24 is increased, and at this time the polarizing light sheet main body 5 is wound around the surface of the guide roller 24 to ensure sufficient drying time for the polarizing light sheet main body 5 and avoid the situation of insufficient drying.

[0052] The linkage assembly 75 includes a first vertical rod 7501 fixedly connected to the bottom of the upper bracket 71, a second vertical rod 7502 is fixedly connected to one side of the lower bracket 73, and a plurality of first teeth 7503 are fixedly connected to the surfaces of the first vertical rod 7501 and the second vertical rod 7502. A first gear 7504 is rotatably installed on the inner wall of the drying box 2, and the surface of the first gear 7504 meshes with the first teeth 7503; a limiting rod 7505 is fixedly installed at the bottom of the lower bracket 73, the bottom of the limiting rod 7505 penetrates through the bottom bracket 72, and the surface of the limiting rod 7505 is slidably connected to the bottom bracket 72; when the upper bracket 71 moves longitudinally, the upper bracket 71 drives the first vertical rod 7501 to move, and the first vertical rod 7501 drives the second vertical rod 7502 to move simultaneously through the first teeth 7503 and the first gear 7504, so that the second vertical rod 7502 moves in the opposite direction to the first vertical rod 7501, thereby driving the lower bracket 73 to move simultaneously, so as to achieve the function of adjusting the distance between the upper guide roller 24 and the lower guide roller 24.

[0053] The specific implementation manner of this embodiment is as follows: When it is necessary to adjust the position of the guide roller 24 according to the thickness of the polarizing light sheet main body 5, the hydraulic cylinder 74 drives the upper bracket 71 to move. The upper bracket 71 drives the upper guide roller 24 to move simultaneously. While the upper bracket 71 is moving, the first vertical rod 7501 moves. The first vertical rod 7501 makes the second vertical rod 7502 move simultaneously through the first tooth 7503 and the first gear 7504, so that the second vertical rod 7502 drives the lower bracket 73 to move simultaneously, and the lower bracket 73 drives the lower guide roller 24 to move, thereby achieving the effect of adjusting the distance between the upper guide roller 24 and the lower guide roller 24.

[0054] Embodiment 3: Please refer to Figures 1 - 16 , the present invention provides a technical solution: A polarizing light sheet production device for liquid crystal display imaging, and the present invention makes corresponding improvements to the technical problems mentioned in the background art.

[0055] As a further limitation of the humidifying unit 8 of the present invention, the humidifying unit 8 includes a box body 81 fixedly installed on the inner wall of the drying box 2. One side of the box body 81 is fixedly communicated with an air inlet box 82. One side of the air inlet box 82 is fixedly communicated with a plurality of air inlet pipes 83. The other side of the box body 81 is fixedly communicated with a second connecting pipe 84 and a conduit 85. Both the second connecting pipe 84 and the conduit 85 are fixedly communicated with the air supply pipe 6201. One end of the conduit 85 extends into the interior of the air supply pipe 6201. An air supply port 8501 is formed on the surface of the conduit 85. A second arc-shaped guide piece 8502 is fixedly installed on the inner wall of the conduit 85. An intermittent component 86 is arranged on one side of the fixing plate 23; wherein, a one-way air inlet valve is fixedly communicated with the bottom of the air inlet box 82; the humidifying mist is sent into the air inlet box 82 through the air inlet pipes 83, and the temperature of the humidifying mist sent by the air inlet pipes 83 is adapted to the temperature of the hot air blown by the hot air blower 21. The humidifying mist in the air inlet box 82 is dispersed in the box body 81 after being guided. And through the second connecting pipe 84, the hot air in the air supply pipe 6201 can enter the box body 81, and the hot air drives the humidifying mist to enter the remaining air supply pipes 6201 through the conduit 85. When the humidifying mist passes through the conduit 85, it is shunted by the second arc-shaped guide piece 8502, and the humidifying mist is dispersed into the air supply pipes 6201 through a plurality of air supply ports 8501 and follows the hot air in the air supply pipes 6201 into the first connecting pipe 6202 and the air distribution pipe 6203, achieving the effect of increasing the humidity of the hot air, thereby ensuring the humidity in the drying box 2 to improve the drying uniformity of the polarizing light sheet main body 5. And through the intermittent component 86, the humidifying mist can enter the drying box 2 intermittently, effectively controlling the amount of the humidifying mist entering, and avoiding the excessive humidity in the drying box 2 from affecting the drying effect of the polarizing light sheet main body 5.

[0056] The intermittent component 86 includes two second gears 8601, which are respectively and fixedly installed at one end of two of the guide rollers 24. Two positioning gears 8602 are rotatably installed on one side of the fixing plate 23. The outer wall of the positioning gear 8602 is engaged with a synchronous toothed belt 8603. A number of second teeth 8604 are fixedly connected to the outer wall of the synchronous toothed belt 8603, and the second teeth 8604 are engaged with the surface of the second gear 8601. A pressing block 8605 is fixedly installed on one side of the synchronous toothed belt 8603. A vertical plate 8606 is slidably connected to the top of the air inlet box 82. The pressing block 8605 and the vertical plate 8606 are used in cooperation. The bottom of the vertical plate 8606 extends into the interior of the air inlet box 82. An interface 8607 is provided on the surface of the vertical plate 8606, and the interface 8607 is communicated with the air inlet pipe 83; a chute 2301 is provided on the surface of the fixing plate 23, and one end of the guide roller 24 penetrates through the chute 2301 and is slidably connected to the inner cavity of the chute 2301; one end of two of the guide rollers 24 among the upper guide rollers penetrates through the chute 2301 and is slidably connected to the inner cavity of the chute 2301. The rotation of the guide roller 24 is caused by the movement of the polarized light sheet body 5, and the guide roller 24 drives the second gear 8601 to rotate; a spring 8608 is fixedly installed on the top of the air inlet box 82, and a support plate 8609 is fixedly installed on one side of the vertical plate 8606. The bottom of the support plate 8609 is fixedly connected to the top of the spring 8608; when the guide roller 24 rotates, it drives the second gear 8601 to rotate. The second gear 8601 drives the synchronous toothed belt 8603 to move through the second teeth 8604. The movement of the synchronous toothed belt 8603 drives the pressing block 8605 to move simultaneously, so that the pressing block 8605 plays a role in pressing down the vertical plate 8606. When the vertical plate 8606 moves downward, the interface 8607 is docked with the pipe orifice of the air inlet pipe 83, so that the humidifying mist in the air inlet pipe 83 enters the air inlet box 82. After the pressing block 8605 is separated from the vertical plate 8606, the spring 8608 makes the vertical plate 8606 reset through the support plate 8609. Through the reset of the vertical plate 8606, the interface 8607 is misaligned with the pipe orifice of the air inlet pipe 83, and the vertical plate 8606 reseals the pipe orifice of the air inlet pipe 83 and no longer allows the humidifying mist to enter, achieving the function of intermittent humidification to effectively control the humidity in the drying box 2.

[0057] The specific implementation of this embodiment is as follows: The intake pipe 83 sends humidified mist into the box body 81 through the intake box 82, and sends hot air into the box body 81 through the second connecting pipe 84, so that the humidified mist is driven by the hot air into the conduit 85 and the remaining air supply pipe 6201, and is dispersed through the air supply port 8501 under the guidance of the second arc-shaped guide piece 8502, and then is brought into the first connecting pipe 6202 and the air distribution pipe 6203 by the hot air in the air supply pipe 6201, playing a role in increasing the humidity in the drying oven 2 to ensure the uniformity of drying the polarizing plate main body 5, and further ensuring the quality of the polarizing plate main body 5. When the guide roller 24 rotates, the guide roller 24 drives the second gear 8601 to rotate. The second gear 8601 drives the synchronous toothed belt 8603 to move through the second gear 8601, and the synchronous toothed belt 8603 is positioned by the positioning gear 8602, so that the synchronous toothed belt 8603 can drive the pressing block 8605 to move simultaneously. When the pressing block 8605 moves following the synchronous toothed belt 8603, it will contact the vertical plate 8606, exerting a downward pressure on the vertical plate 8606. And through the downward movement of the vertical plate 8606, the interface 8607 is docked with the pipe orifice of the intake pipe 83, so that the humidified mist in the intake pipe 83 enters the intake box 82. After the pressing block 8605 is separated from the vertical plate 8606, the spring 8608 makes the vertical plate 8606 reset through the support plate 8609. Through the reset of the vertical plate 8606, the interface 8607 is misaligned with the pipe orifice of the intake pipe 83, and the vertical plate 8606 reseals the pipe orifice of the intake pipe 83 and no longer allows the humidified mist to enter, achieving the function of intermittent humidification, effectively controlling the humidity in the drying oven 2, improving the drying uniformity of the polarizing plate main body 5, avoiding the polarizing plate main body 5 from becoming brittle or having local over-drying or over-wetting conditions, and ensuring the quality of the polarizing plate main body 5.
