[0002] The friction cloth roller is a tool specifically designed for the LCD industry, primarily used in the optical alignment process. It secures the friction cloth to achieve uniform treatment of the display panel surface. The friction cloth roller's design ensures proper friction during processing, precisely controlling the uniformity and quality of the surface treatment, thereby improving the alignment of liquid crystal molecules and ensuring the optical performance of the display panel. The use of a friction cloth roller trolley ensures consistency and stability in each process, reducing quality issues caused by uneven friction, and ultimately improving production efficiency and product quality.

[0003] Traditionally, rubbing cloth rollers are used in the LCD industry's optical alignment process to achieve uniform surface treatment by securing a rubbing cloth to the roller's surface. During the conveying process, the roller rolls over the display panel, where the rubbing cloth contacts the panel surface and generates appropriate friction, thereby achieving uniform alignment of the liquid crystal molecules. This method effectively controls the uniformity and stability of the rubbing process, ensuring the ideal surface treatment of the display panel, thereby improving the product's optical performance and quality stability.

[0004] Traditional friction cloth rollers require manual frequent handling between storage units and equipment. After long hours of operation, this increases labor intensity, reduces operational efficiency, and also causes positional deviation, making it difficult to ensure stable positioning.

[0026] Reference Figure 3The support plate 5 is provided with a slide groove 8, and the support plate 5 is internally slidably connected with a slider 9, and the slider 9 is fixedly connected with a bearing 10. The inner wall of the bearing 10 is fixedly connected with a bidirectional screw 11, and the friction generated when the bidirectional screw 11 rotates is reduced by the bearing 10. The upper surface of the bidirectional screw 11 is fixedly connected with a connecting block 15, and the connecting block 15 drives the support table 6 to move with the movement of the slider 9. Both ends of the bidirectional screw 11 are fixedly connected with a handle 12, and the driving handle 12 drives the bidirectional screw 11 to rotate. The outer wall of the bidirectional screw 11 is provided with a fixing component, which is used to fix the support table 6. The fixing component includes a clamping block 13, and the internal thread of the clamping block 13 is connected to the outer wall of the bidirectional screw 11. The outer wall of the clamping block 13 is fixedly connected to the limiting block 14, and the outer wall of the limiting block 14 is slidably connected to the inside of the slider 9. The block 13 is used to limit the block 13, and the engagement of the bidirectional screw 11 with the block 13 makes the block 13 slide inside the slider 9 and the support plate 5 due to the rotation of the bidirectional screw 11. Finally, the block 13 is conveniently fixed with the block 13. At the same time, the block 13 is limited by the limit block 14 to prevent the block 13 from excessive movement. The outer wall of the block 13 is slidably connected to the inside of the slide groove 8.

Finally, the friction cloth is placed on top of the support table 6 and fixed by bolts, etc. Finally, the trolley frame 1 and the friction cloth above it are moved by the operating handle 4 in conjunction with the movable caster 2.
