Abstract

The present invention discloses a slit nozzle cleaning device for coaters. The slit nozzle cleaning device for coaters comprises a heating source, a crucible and a mixing means, the heating source is used to heat the materials in the crucible; the mixing means is used to mix the materials in the crucible. The mixing means is used to mix the materials in the crucible, thus a uniform heating environment in the crucible can be formed.

First claim

What is claimed is:

1. A slit nozzle cleaning device for coaters, the slit nozzle cleaning device for coaters comprising a cleaner, an adhesive removing dissolvent supply unit and a discharge unit, wherein the cleaner is provided with a groove for engaging with a slit nozzle, two opposite side walls of the groove are provided with adhesive removing dissolvent supply through holes, the adhesive removing dissolvent supply unit is in fluid communication with the adhesive removing dissolvent supply through holes so as to supply adhesive removing dissolvent into the groove, a bottom wall of the groove is provided with discharge holes, the discharge unit is in fluid communication with the discharge holes, wherein the bottom wall of the groove is provided with one row of discharge holes.

2. The slit nozzle cleaning device for coaters of claim 1 , wherein two opposite side walls of the groove are provided with multiple adhesive removing dissolvent supply through holes.

3. The slit nozzle cleaning device for coaters of claim 1 , wherein two opposite side walls of the groove are provided with at least one row of adhesive removing dissolvent supply through holes respectively, the at least one row of adhesive removing dissolvent supply through holes are arranged along a longitudinal direction of the cleaner.

4. The slit nozzle cleaning device for coaters of claim 1 , wherein the discharge holes are not aligned with a photo resist discharge slit of the slit nozzle in a vertical direction.

5. The slit nozzle cleaning device for coaters of claim 1 , wherein the bottom wall of the groove is provided with two rows of discharge holes.

6. The slit nozzle cleaning device for coaters of claim 1 , wherein there is provided with an engagement gap between the groove of the cleaner and the slit nozzle.

7. The slit nozzle cleaning device for coaters of claim 1 , wherein there is provided with one row of adhesive removing dissolvent supply through holes along a longitudinal direction of the cleaner.

8. The slit nozzle cleaning device for coaters of claim 1 , wherein there is provided with two rows of adhesive removing dissolvent supply through holes along a longitudinal direction of cleaner.

9. The slit nozzle cleaning device for coaters of claim 1 , wherein a length of the cleaner is equal to a length of the slit nozzle.

10. The slit nozzle cleaning device for coaters of claim 1 , wherein the cleaner is a cleaner made of rubber.

11. The slit nozzle cleaning device for coaters of claim 1 , wherein the adhesive removing dissolvent supply unit comprises a pressure tank for receiving adhesive removing dissolvent, the pressure tank is in fluid communication with the adhesive removing dissolvent supply through holes via a pipeline.

12. The slit nozzle cleaning device for coaters of claim 11 , wherein the discharge unit comprises a vacuum pump, the vacuum pump is in fluid communication with the discharge holes via a pipeline.

13. The slit nozzle cleaning device for coaters of claim 12 , wherein the discharge unit comprises a waste tank, the vacuum pump is in fluid communication with the waste tank.
