Abstract

The invention discloses a waste liquor drainage tank for a slit nozzle and a slit nozzle cleaning device, relates to the technical field of slit nozzles and aims to solve the problem of poor liquor drainage effect of an existing waste liquor drainage tank due to the fact that glue liquor easily remains at the bottom of a groove. The waste liquor drainage tank comprises a body, a groove is formed in the upper surface of the body, a waste liquor drainage channel is arranged at the bottom of the groove, the side surface of the groove comprises at least one inclined surface, the bottom end of the inclined surface is inclined along the direction far away from the corresponding outer side surface of the body relative to the top end of the inclined surface and connected with the waste liquor drainage channel, and the inclined surface is a plane or arc face. The waste liquor drainage tank is used for draining the glue liquor remaining in the slit nozzle.

Description

technical field [0001] The invention relates to the technical field of slit nozzles, in particular to a waste liquid tank for slit nozzles and a slit nozzle cleaning device. Background technique [0002] In the production process of the display panel, a slit nozzle (Slit Nozzle) is used to apply glue to the substrate. Since some glue (such as photoresist) is easy to dry and solidify, it will be inside and outside the slit of the slit nozzle. Agglomeration on the side, which in turn causes uneven glue application, SIJI MURA (a proper term, meaning a bright line parallel to the long side of the substrate found during macroscopic inspection after glue application) and other undesirable phenomena. Clean the crevice nozzle regularly. [0003] When cleaning, firstly, the residual glue in the slit nozzle should be discharged into the waste liquid tank. The waste liquid tank in the prior art is as follows: figure 1 As shown, including the body 01, the upper surface of the body 01 ...
