Description

Cutting structure for cutting liquid crystal alignment cloth

technical field

The utility model relates to a cutting structure, in particular to a cutting structure for cutting liquid crystal alignment cloth.

Background technique

RUBBING (alignment process) refers to rubbing a soft liquid crystal alignment cloth in a certain direction on the alignment film made of Polyimide resin to rub grooves on the surface of the alignment film that allow the liquid crystals to be arranged in a certain direction. The alignment film is a necessary thing to constrain the liquid crystal to be parallel to the substrate, and RUBBING is a necessary action to make the liquid crystal align in parallel. Therefore, the liquid crystals can be arranged in a certain direction. In addition, in order for the liquid crystals to stand in the same direction, a pre-tilt angle must be given. For this reason, the grooves of liquid crystal alignment must be produced through RUBBING. In addition, the size of the pre-tilt angle generated by RUBBING varies with the conditions of RUBBING (rotational speed of the ROLLER, the use of cloth, the pressure of the cloth, etc.), and the different materials of the alignment film. Therefore, RUBBING is very important in the manufacturing engineering of liquid crystal display.

The existing cutting structure for cutting liquid crystal alignment cloth includes a machine table and a spacer. The spacer is laid on the machine platform. The alignment cloth is laid on the spacer, and after the predetermined cutting area is marked on the surface of the alignment cloth, it is manually cut with a cutter.

1. The alignment cloth will be stained with a lot of dandruff on the spacer, so after cutting, it is necessary to clean up a large amount of dander on the alignment cloth, otherwise it will affect the force between the liquid crystal and the liquid crystal. The dander process is quite time-consuming and laborious;

2. The alignment cloth cannot be laid flat on the machine table, resulting in the problem that the cut alignment cloth has different sizes;

3. The traditional method of marking the predetermined cutting block of the alignment cloth is relatively inaccurate, resulting in the problem that the cut alignment cloth has different sizes;

4. Manual cutting is very time-consuming and labor-intensive.
