Description

Technical Field

[0001] The utility model relates to the technical field of photoresist waste liquid collecting devices of coating machines, in particular to a photoresist waste liquid collecting device of coating machines. Background Art

[0002] The production of color filters generally adopts the form of slit nozzle coating, which requires a coating machine to coat the photoresist that can evaporate quickly. During the coating process, the coating machine will produce photoresist waste liquid. The photoresist waste liquid is highly volatile. If a large amount of it accumulates, it is easy to cause fire or explosion. Therefore, a corresponding device is needed to recycle the photoresist waste liquid.

[0003] The device commonly used on the coating machine to recycle the photoresist waste liquid includes a recovery box, a waste liquid cooling unit and a waste liquid steam discharge unit. The waste liquid cooling unit is used to reduce the temperature of the photoresist waste liquid in the recovery box and reduce the volatilization rate of the photoresist waste liquid. The waste liquid steam discharge equipment is used to promptly discharge the volatilized gas of the photoresist waste liquid in the recovery box to prevent fire hazards caused by gas accumulation, and at the same time avoid the gas condensing into photoresist liquid or solid again, polluting or clogging the photoresist waste liquid collection device.

[0004] At present, the photoresist glue waste liquid collecting device of the coating machine in the prior art usually connects the photoresist glue waste liquid circulation pipeline with the recycling box. When the photoresist glue waste liquid enters the recycling box, some solid particles, such as impurities, residues, etc., will be mixed into the photoresist glue waste liquid during the coating process, which will lead to an increase in the subsequent cost of photoresist glue liquid treatment. Therefore, it is necessary to filter the photoresist glue waste liquid, and when replacing the filter, the filter is generally installed and fixed by screws, which makes the removal of the filter cumbersome and inconvenient. There is a problem that the removal of the filter is cumbersome. Utility Model Content
