Problems solved by technology

[0005] There are two ways of laying the friction cloth on the platform 5, namely, cloth hair facing up and cloth hair facing down: cloth hair facing up can restore the friction cloth to a better surface morphology, but it takes a long time, usually After 8 hours, local folds can still be seen; although facing downwards can shorten the time for flattening the friction cloth, after flattening, the surface morphology of the cloth is poor
[0006] At the same time, each layer of the aging device in the prior art can only spread one piece of friction cloth flatly, and due to the limitation of the height (the height of taking and putting the cloth), each aging device can age at most 15 pieces of friction cloth at the same time. In order to meet the large demand for mass production of friction cloth, it is necessary to purchase multiple aging devices of the prior art to perform aging at the same time, thus increasing the equipment cost
[0007] In addition, there is an aging method of rubbing cloth, such as image 3 As shown, 4 pieces of rubbing cloth are placed on the pole 8. Although this aging method can shorten the time for the flattening of the rubbing cloth 4, it is not conducive to the directionality of the rubbing cloth 4.

Embodiment 1

[0034] This embodiment provides a rubbing cloth aging device, which is used to flatten the rubbing cloth and orient the hairs of the rubbing cloth according to a set direction, including an adsorption unit, which is used to make the cloth surface of the rubbing cloth along a predetermined plane Set, and can absorb and flatten the rubbing cloth, the range of the included angle θ between the predetermined plane and the horizontal plane is 60°≤θ≤90°.

[0035] The setting of the adsorption unit enables the friction cloth to be flattened under the joint action of gravity and the adsorption force of the adsorption unit, which greatly speeds up the flattening speed of the friction cloth; The plane can be adjusted and placed arbitrarily, so that the cloth wool can be oriented according to the set direction, thereby improving the aging quality of the friction cloth.

[0036] In this embodiment, the angle θ between the predetermined plane and the horizontal plane is 90°. Such as Figu...

Embodiment 2

[0047] This embodiment provides a friction cloth aging device, which is different from Embodiment 1, such as Figure 8 As shown, the vacuum parent chamber 1 includes two adsorption chamber walls 11 arranged along a predetermined plane, and the included angle θ between the predetermined plane and the horizontal plane is 60°.

[0048] Other structures of the rubbing cloth aging device in this embodiment are the same as those in Embodiment 1, and will not be repeated here.

[0049] Beneficial effects of embodiment 1-2: the friction cloth aging device provided in embodiment 1-2, by setting the adsorption unit, the friction cloth can be flattened under the joint action of gravity and the adsorption force of the adsorption unit, thereby greatly speeding up the aging process. The flattening speed of the friction cloth is improved; at the same time, since the cloth surface of the friction cloth provided with cloth hair can be rotated at any angle along the predetermined plane to adjus...

Abstract

The present disclosure provides a system for aging rubbing cloth (4) used in the liquid crystal display (LCD) manufacturing process. The rubbing cloth (4) aging system includes a suction module configured to provide suction force to hold a piece of rubbing cloth (4) for aging and a supporting frame (2) configured to support the suction module. Further, the suction module holds the piece of rubbing cloth (4) on a pre-determined plane and flattens the piece of rubbing cloth (4).

Description

technical field [0001] The invention relates to the technical field of manufacturing liquid crystal display products, in particular to a rubbing cloth aging device. Background technique [0002] The rubbing process in the liquid crystal panel box forming process refers to rubbing the surface of the alignment film on the array substrate and the color filter substrate with nylon cloth, fiber or cotton cloth in a certain direction, so as to form grooves for liquid crystals to be arranged at a pre-tilt angle. The process is called liquid crystal molecular alignment technology. In the rubbing process, the nylon cloth, fiber or cotton cloth used are collectively referred to as rubbing cloth. The quality of the rubbing process depends on the quality of the rubbing cloth itself on the one hand, and on the other hand the aging quality of the rubbing cloth before it is used in the rubbing process. Therefore, the aging of the rubbing cloth is a crucial and indispensable step for the ...
