Problems solved by technology

[0005] However, since the pitch of the pipeline through which the coating liquid moves is the same as the pitch of the discharge port, when a foreign substance gets stuck in the pipe, clogging occurs, and the coating liquid is ejected from the discharge port due to the clogged part. splash problem
Therefore, the coating liquid cannot be stably and uniformly coated on the glass surface due to foreign substances, causing many problems of display quality defects

Abstract

The present invention relates to an in-shower knife for coating a surface of a display glass which can prevent a coating liquid from being cracked and discharged due to foreign matters trapped in a pipeline, thereby minimizing quality defects of a display caused by uneven application of the coating liquid to the glass. Even if partial clogging occurs in a secondary pipe due to the foreign matters,the coating liquid passing through a tertiary pipe is temporarily collected in a buffer part and is discharged without being cracked through a discharge port. Accordingly, the coating liquid is evenly and uniformly applied to the surface of the glass, thereby minimizing the occurrence of display quality defects.

Description

technical field [0001] The invention relates to a spray inner knife, more specifically, a spray knife for coating the glass surface of a display screen, which prevents splashing of the coating liquid during spraying caused by filtered foreign matter in the pipeline, Thus, it is possible to minimize the problem of display quality defects caused by uneven coating of the coating liquid. Background technique [0002] Generally, water or chemicals are applied to the glass surface during the cleaning process or the process of applying chemicals between the various processes of display manufacturing such as LCD and OLED. , in the process of manufacturing the display, through the process of cleaning, etching, demoulding and developing, this process of spraying water or medicine is repeated many times, so when it is coated on the glass surface, it can be used on the glass surface It is especially important that the entire area is sprayed consistently and evenly. [0003] The applic...
