Description
Technical Field
[0001] The utility model relates to the technical field of polarizer repair, and more specifically, to a device for repairing the warping of a polarizer. Background Art
[0002] In the liquid crystal display (LCD) industry, as one of the core materials, the polarizer plays a crucial role. It is responsible for controlling the transmission and blocking of light, thereby ensuring that the display screen can present clear and accurate images. However, although the polarizer undergoes strict quality control during the production process, it may still be affected by various factors during subsequent transportation, storage, and use, resulting in warping. The main reasons for the warping of the polarizer include, but are not limited to: the change in environmental humidity causes the internal stress of the material to be unbalanced; the thermal expansion and contraction effect caused by temperature changes; and mechanical stress (such as improper handling or stacking methods), etc. These factors work together to cause the polarizer to bend in the length or width direction, thereby affecting its adhesion to the liquid crystal panel, ultimately leading to a decline in display quality and even affecting the overall performance of the product;
[0003] To address this problem, the methods commonly used in the industry at present include optimizing the storage environment, improving the packaging method, and strengthening the protection measures during transportation, etc. However, although these methods can reduce the occurrence of polarizer warping to a certain extent, they cannot completely eliminate this problem. Especially for the warped polarizer, the traditional treatment method is often to directly scrap it, which not only causes a great waste of resources but also increases the production cost. Therefore, we make improvements and propose a device for repairing the warping of a polarizer. Summary of the Utility Model

[0028] As described in the background art, the methods commonly used in the current industry include optimizing the storage environment, improving the packaging method, and strengthening the protection measures during transportation, etc. However, although these methods can reduce the occurrence of polarizer warping to a certain extent, they cannot completely eliminate this problem. Especially for polarizers that have already warped, the traditional treatment method is often to directly scrap them, which not only causes a great waste of resources but also increases the production cost.
[0029] To solve this technical problem, this utility model provides a device for repairing the warping of a polarizer, which is applied to the repair of polarizer warping.
[0030] Specifically, please refer to Figure 1, The device for repairing the warping of a polarizer specifically includes:
[0031] A sealed box 1, in which two sets of pressing sheets 3 are arranged. The warped polarizer is placed between the two sets of pressing sheets 3 to achieve the pressing and resetting of the warped polarizer by the two sets of pressing sheets 3.
[0032] The device for repairing the warping of a polarizer provided by the present utility model places the warped polarizer between two sets of pressing sheets 3.

[0033] In order to enable those skilled in the art to better understand the solution of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings.
[0034] It should be noted that, without conflict, the embodiments in the present utility model and the features and technical solutions in the embodiments can be combined with each other.
[0035] It should be noted that similar reference numerals and letters denote similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.
[0036] Embodiment 1 of the device for repairing the warping of a polarizer of the present utility model
[0037] Please refer to Figure 1 , the device for repairing the warping of a polarizer of the present utility model includes: a sealed box 1, in which two sets of pressing sheets 3 are arranged. The warped polarizer is placed between the two sets of pressing sheets 3 to achieve the pressing and resetting of the warped polarizer by the two sets of pressing sheets 3. For the convenience of understanding, the present application uses A to represent the warped polarizer and marks it in the figure; setting the sealed box 1 can create a relatively independent and stable repair space, avoiding the entry of pollutants such as dust and impurities from the outside, thereby ensuring the purity of the repair process. The two sets of pressing sheets 3 inside can evenly apply pressure to the warped polarizer, ensuring that all parts of the polarizer can be subjected to a balanced pressing effect, which helps to achieve overall flat repair. This design provides a reliable environment for the repair of the polarizer, improving the stability and reliability of the repair;
[0038] By placing the warped polarizer between two sets of extrusion sheets 3, the two sets of extrusion sheets 3 can effectively improve the warping state of the polarizer and restore its flatness through a simple physical extrusion method, greatly improving the repair efficiency and success rate. Compared with traditional repair methods, this solution does not require complex equipment and expensive materials, greatly reducing the repair cost. By repairing the warping problem of the polarizer, the utilization rate of the polarizer and the product yield are improved, and the waste of resources caused by scrapping is significantly reduced.
[0039] Furthermore, each set of extrusion sheets 3 is composed of several pieces of foam. The foam has good softness and elasticity and can play a buffering role during the extrusion process. When applying pressure to the polarizer, the foam can disperse the pressure, avoiding damage to the polarizer such as scratches and cracks caused by excessive local pressure. In addition, the contact between the foam and the polarizer is softer, reducing the frictional damage caused by hard contact, thereby maximizing the protection of the surface quality and optical performance of the polarizer.
[0040] Furthermore, a desiccant is also provided in the sealed box 1. The desiccant can absorb the moisture in the sealed box 1 during the repair process, thereby facilitating the repair of the polarizer. Setting a desiccant in the sealed box 1 can effectively control the environmental humidity. The polarizer is sensitive to humidity. Excessive humidity may affect the viscosity of the glue, cause the polarizer to deform or have other adverse effects. The desiccant can timely absorb the moisture in the sealed box 1 and maintain a relatively dry environment, which helps to improve the repair effect and quality. This enables the polarizer to maintain stable physical and chemical properties during the repair process and ensures the smooth progress of the repair work.
[0041] Embodiment 2 of the device for repairing the warping of the polarizer of the present utility model
[0042] For the device for repairing the warping of the polarizer of the present utility model, further, as Figure 2 shown, the sealed box 1 includes a box body 101. The top of the box body 101 is connected with a box cover 107 through a buckle. The box cover 107 and the box body 101 can cooperate to provide a relatively sealed environment for the repair of the polarizer. After opening the buckle, the box cover 107 can be removed. The box cover 107 and the box body 101 are connected by a buckle. While ensuring tight sealing, the operation is simple and fast. The buckle connection has good tightness and can effectively prevent the box cover 107 from accidentally opening during the repair process, thus ensuring the stability of the internal environment.
[0043] Further, as Figures 2 - 4 shown, a chute 102 is opened at the bottom of the inner cavity of the box body 101. A bidirectional lead screw 103 is rotatably connected in the chute 102 through a bearing. One end of the bidirectional lead screw 103 passes through the box body 101 and is fixedly connected with a hand wheel 106. The setting of the hand wheel 106 facilitates the rotation of the bidirectional lead screw 103.
[0044] Furthermore, as Figures 3 - 5 shown, two sliders 104 are threadedly connected to the outer surface of the bidirectional lead screw 103. Clamping plates 105 are fixedly connected to the tops of the two sliders 104. One sides of the two clamping plates 105 close to each other are respectively in contact with two groups of pressing sheets 3. The bidirectional lead screw 103 can adjust the positions of the clamping plates 105 through the sliders 104, thereby reducing the usage amount of the pressing sheets 3 and facilitating the pressing of the pressing sheets 3 against the polarizing plate. The adjustable positions of the clamping plates 105 enable the device to adapt to polarizing plates of different sizes and warping degrees. For smaller or less warped polarizing plates, the usage amount of the pressing sheets 3 can be reduced, thereby reducing costs. At the same time, the adjustment of the positions of the clamping plates 105 can ensure that the pressing sheets 3 can more accurately align with the warped parts of the polarizing plate, apply more effective pressure, and improve the repair effect. This flexible design also facilitates the real-time adjustment of the pressure distribution according to the changes of the polarizing plate during the repair process, ensuring the accuracy and efficiency of the repair work.
[0045] Embodiment Three of the Device for Repairing Warping of a Polarizing Plate of the Present Utility Model
[0046] Furthermore, as Figure 5 shown, an opening is provided in the side wall of the sealed box 1. A drying box 2 is fixedly installed in the opening. A plurality of first air ports 201 are provided on one side of the drying box 2 close to the inside of the box body 101. A bagged desiccant is placed in the drying box 2. The drying box 2 provides a placement space for the bagged desiccant, ensuring the uniform distribution of the desiccant. This helps the desiccant to play a more effective moisture absorption role and improve the moisture absorption efficiency. At the same time, reducing the scattered distribution of the desiccant also reduces the risk of damage caused by the direct contact between the desiccant and the polarizing plate, ensuring the safety of the polarizing plate.
[0047] Furthermore, as Figure 5 shown, a placement and removal opening is provided on one side of the drying box 2 away from the first air ports 201. A sealing plate 202 for blocking the placement and removal opening is connected to the side surface of the box body 101 by a buckle. After opening the sealing plate 202, the bagged desiccant can be taken out from the placement and removal opening for replacement of the bagged desiccant. The design of the placement and removal opening and the sealing plate 202 greatly facilitates the replacement operation of the bagged desiccant. When the desiccant is saturated with moisture absorption, it can be replaced in a timely and rapid manner to ensure that the desiccant always maintains good moisture absorption performance. The sealing plate 202 is connected by a buckle, which can not only ensure the sealing performance during normal use but also be easily opened when the desiccant needs to be replaced. The operation is simple and convenient, which helps to maintain the dry environment in the sealed box 1 and ensure the quality and effect of polarizing plate repair.
[0048] Furthermore, as Figure 5As shown in the figure, a sealing plate 203 located within the first air port 201 is slidably connected to the outer surface of the drying box 2. A number of second air ports 204 are provided on the sealing plate 203, and the positions of the second air ports 204 correspond to those of the first air port 201. The top of the sealing plate 203 contacts the bottom of the box cover 107. When the box cover 107 is installed on the top of the box body 101, the sealing plate 203 is limited, enabling the second air port 204 and the first air port 201 to remain in communication. The bagged desiccant can absorb the moisture within the box body 101 through the second air port 204 and the first air port 201. After the box cover 107 is removed, the limitation on the sealing plate 203 is released. At this time, the sealing plate 203 rises, causing the second air port 204 and the first air port 201 to be misaligned. This setting can reduce the situation where the bagged desiccant absorbs moisture from the external air after the box cover 107 is opened. This automatic control mechanism requires no manual intervention and is accurate and reliable.
[0049] Furthermore, as Figure 5 shown in the figure, a chamber 205 is provided within the box body 101. The bottom end of the sealing plate 203 extends into the chamber 205, and a spring 206 is fixedly connected between the bottom end of the sealing plate 203 and the chamber 205. The force of the spring 206 can push the chamber 205 upward.

The accompanying drawings show the preferred embodiments of the present invention, but do not limit the patent scope of the present invention. The present invention can be implemented in many different forms. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosed content of the present invention more thorough and comprehensive.
