Problems solved by technology

Once the generated elastomer powder enters the nozzle or adheres to the nozzle face, it will cause the elastomer powder to be mixed into the solution, which will damage the quality of the functional film formed on the substrate
[0006] Also, sometimes the scraping operation is insufficient due to the deterioration of the elastomer scraper, etc.
In addition, it is difficult to remove the remaining coating liquid attached to the elastomer scraper itself, and sometimes the remaining solution scraped off will adhere to the nozzle surface of the inkjet head again.
[0007] In the latter technique, a sufficient suction effect of the remaining coating liquid may not be obtained in some cases

Abstract

The ink-jetting coating device of the present invention includes one spray head with nozzles to jet solution to the base plate as well as one absorptive wiping belt, one ejecting mechanism to set the absorptive wiping belt in the front of the nozzles and one roller to push the absorptive wiping belt to the nozzle surface.

Description

(1) Technical field [0001] The present invention relates to an inkjet coating device having a nozzle surface cleaning device of an inkjet head for cleaning the nozzle surface of the inkjet head, and an inkjet head cleaning method. (2) Background technology [0002] In the prior art, in an inkjet head that applies a solution for forming a functional thin film such as a resist film or an alignment film to the surface of a substrate using an inkjet head method, as a method for cleaning the nozzle surface of the inkjet head, There is a technology of scraping off the remaining coating liquid while pressing an elastic body scraper made of silicone rubber against the nozzle surface of the inkjet head. [0003] In addition, Japanese Patent Laying-Open No. 6-115083 (Patent Document 1) discloses a through hole for air suction on the elastic scraper itself, and the residual ink adhering to the elastic scraper is removed by a suction pump. attractive technology. [0004] The prior art...
