Abstract

The invention discloses a spray nozzle cleaning device and a coating machine. The spray nozzle cleaning device is used for cleaning a spray nozzle of the coating machine, and comprises a cleaner, a recovery tank, a recovery pipeline, a vacuum pumping pipeline and a back pressure air exhaust device. The cleaner comprises a solvent recovery opening. One end of the recovery pipeline is connected withthe solvent recovery opening, and the other end of the recovery pipeline is connected with the recovery tank. The two ends of the vacuum pumping pipeline are connected with the recovery tank and theback pressure air exhaust device correspondingly.

Description

technical field [0001] The present invention relates to a nozzle cleaning device and a coating machine using the nozzle cleaning device. Background technique [0002] In the production process of the display panel, a linear photoresist coater needs to be used for the photoresist coating process. There is a common gel problem in the photoresist coating process, that is, after the photoresist coating is completed, part of the photoresist remains on and around the nozzle tip. Defects will be formed when the nozzle tip is not clean, which will seriously affect the product yield. Therefore, the nozzles need to be cleaned before photoresist coating of each piece of glass. [0003] At present, the more effective way is to spray a corrosive solvent through the nozzle cleaning device to clean the nozzle, while the existing nozzle cleaning device is usually powered by a vacuum pump to absorb the residual solvent of the solvent, because the solvent is volatile and corrosive. , the v...
