Description

Technical Field

[0001] The utility model relates to the technical field of polarizing films, in particular to a protective film re-sticking mechanism for a rolled polarizing film. Background Art

[0002] A polarizer is an optical film composed of multiple layers of polymer materials that has the function of producing polarized light. It can convert non-polarized natural light into polarized light, allowing light that is perpendicular to the electric field to pass through, so that the liquid crystal display panel can display images normally. It is an indispensable part of LCD imaging.

[0003] During the lamination process of the polarizer, air generated during the lamination may cause bubbles, resulting in defective finished products. Therefore, the polarizer and the protective film need to be re-laminated to ensure the reuse of materials and improve material economy. However, the existing device cannot press at the same time during the lamination process, which will cause bubbles to be generated during the re-lamination process, resulting in excessive waste of materials.

[0025] Embodiment 1: A roll-type polarizer protective film re-sticking mechanism, such as Figure 1-Figure 4 As shown, it includes an adjusting bolt 1, and a rotating support plate 2 arranged at the lower end of the adjusting bolt 1, the rotating support plate 2 is threadedly screwed with the adjusting bolt 1, the adjusting bolt 1 extends out of the lower end of the rotating support plate 2, at least two sliding frames 3 are fixedly connected to the outer side of the rotating support plate 2, the lower end of the adjusting bolt 1 is rotatably connected to an adjusting support frame 4, a triangular moving frame 6 is arranged below the adjusting support frame 4, a secondary pressure plate 7 is arranged on one side of the triangular moving frame 6, and a moving handle 14 is arranged above the sliding frame 3. When the device is running, the adjusting bolt 1 is rotated under the rotating support of the rotating support plate 2, so that the height of the adjusting bolt 1 is adjusted under the threaded support of the rotating support plate 2, so that the adjusting bolt 1 can be adjusted under the threaded support of the rotating support plate 2, thereby adjusting the height of the adjusting bolt 1 under the rotating support of the rotating support plate 2. Under the rotation support of the whole bolt 1, the adjustment support frame 4 and the triangular movable frame 6 and the secondary pressure plate 7 below are moved in height at the same time, so as to achieve the effect of adjusting the height of the triangular movable frame 6 and the secondary pressure plate 7. The pressure of the triangular movable frame 6 is used to ensure that the polarizer is pressed when it is re-pasted. At the same time, the secondary pressing movement of the secondary pressure plate 7 can continuously squeeze the material when the film is pasted to prevent air from causing bubbles, so as to improve the safety and stability when the polarizer is re-pasted. In addition, the limiting and support of the sliding frames 3 on both sides of the rotating support plate 2 can ensure the stability and reliability of the rotating support plate 2 when it rotates and supports the adjustment bolt 1.

[0026] like Figure 1-Figure 4As shown, the lower end of the adjustment support frame 4 is fixedly connected with a connecting plate 5, and the connecting plate 5 is fixedly connected to the secondary pressure plate 7.
