Apparatus and method for producing thin film with coating film

Abstract

The present invention provides a manufacturing device and a manufacturing method, being able to prevent wind porphyritic texture, rope lines, surface is not flat with coating membrane manufacturing device and manufacturing method of thin film. The manufacturing device includes: a coating device and a drying device, wherein the coating device moves from the continuous strip of the bearing body of the coating surface coating liquid between the coating and the standby location and with in a mobile between the mobile mechanism of the coating head, and the ribbon coating surface of the bearing of backup roll bearing dorsal; the drying device sets up by following closely behind the coater of shell structure, the drying device is equipped with: from coating head to drying device between the face side of the base material and base material coated surface of the back side to cover part of the shell and the integration of wind; at least from the coating head to drying device between the coated surface side of the base material for covering the movable type, the coating head is provided with a wind deflectorfrom the coating to drying device between the face side of the base material for cover and fixed in coating head.

Description

technical field [0001] The present invention relates to a manufacturing device and a manufacturing method of a thin film with a coating film, in particular to a manufacturing device and a manufacturing method of a thin film with a coating film composed of a coating device and a drying device. The coating device includes: a coating head, It applies a coating liquid to the surface of a continuously moving belt-shaped support body, and has a forward and backward movement mechanism that moves forward and backward between a coating position and a standby position; a back-up roller, which supports the coating surface of the belt-shaped support body Supported on the rear side, the drying device is formed by a housing arranged immediately behind the coating device. Background technique [0002] Various electronic displays are produced by coating a coating liquid such as a photosensitive material on a tape-shaped support such as a plastic film (hereinafter referred to as a substrate)...

AI Technical Summary

Problems solved by technology

[0007] However, in the coating and drying method and device of Patent Document 1, it is not sufficient to prevent lines or irregularities (surface unevenness), especially when coating a coating liquid containing an organic solvent with a boiling point of 78° C. or lower. In some cases, it is easy to find wind-spotted lines, rope-like lines, and uneven surfaces. Such problems have not been solved.
