Problems solved by technology
[0005] (1) Manually winding the friction cloth is inefficient, and it is easy to cause problems such as uneven attachment and offset;
[0006] (2) In the winding process, human factors have a great influence, and the extrusion strength of the raw material roller to the friction cloth cannot be monitored, and the winding strength of the friction cloth on the raw material roller cannot be accurately controlled, resulting in the width of the gap after the friction cloth is attached has a difference

The invention discloses a friction roller manufacturing device which is used for winding friction cloth on a raw roller to manufacture a friction roller and comprises a support component and a cabinet. The support component is used for supporting the raw roller; the cabinet is used for supporting the friction cloth, a suction structure is arranged on the cabinet and is communicated with exhaust pipes of exhaust equipment, and the friction cloth is sucked by the exhaust equipment via the suction structure, so that the winding strength of the friction cloth on the raw roller can be controlled. The friction roller manufacturing device has the advantages that the friction roller manufacturing device is provided with the cabinet and adjustable exhaust channels, so that the winding strength of the friction cloth can be adjusted in real time in winding procedures, the uniformity of the widths of gaps formed after the friction cloth is attached to the raw roller can be guaranteed, and the friction roller manufacturing device is beneficial to manufacturing liquid crystal display panels.
Description
technical field [0001] The invention relates to the field of display technology, in particular to a friction roller manufacturing device. Background technique [0002] Thin film transistor display (TFT-LCD) technology has been developed in recent decades, and its technology and process are becoming more and more mature. Thin-film transistor displays have replaced cold-cathode diode (CCFL) displays as mainstream products in the display field. In the production process of LCD panels, in order to make the liquid crystal molecules align normally, it is necessary to coat a layer of polyimide film on the surface of the array substrate and the color filter substrate, and then perform a rubbing process to realize the alignment of the liquid crystal molecules. Generally speaking, the rubbing process rotates the rubbing roller and makes the rubbing roller contact and rub against the alignment film to make the polyimide film form an orientation groove with a certain degree of consiste...
