Problems solved by technology

Therefore, there is a risk that the drying nozzles on the upstream side continue to perform an inappropriate drying process
[0007] In addition, in Patent Document 2, it is not clearly indicated how to measure the temperature of each part of the substrate
In addition, Patent Document 2 neither discloses the technical idea of ​​controlling the heating unit (or cooling unit) based on the temperature measurement results of each part as in Patent Document 1, nor does it give any suggestion

Embodiment Construction

[0064] Embodiments of the present invention will be described below with reference to the drawings. In addition, the constituent elements described in this embodiment are merely illustrative, and are not intended to limit the scope of protection of the present invention thereto. In addition, in the drawings, the size or number of each part may be exaggerated or simplified as necessary for easy understanding.

[0065]

[0066] figure 1 It is a schematic configuration diagram showing the coating film forming system 1 including drying devices 3A and 3B according to the embodiment.

[0067] This coated film forming system 1 continuously conveys a substrate 5 which is, for example, a long metal foil in a roll-to-roll system, and coats both surfaces of the substrate 5 containing A slurry coating solution of active substances. Then, the drying treatment of this coating liquid is performed, and the electrode of a lithium ion secondary battery is manufactured.

Abstract

The present invention provides a technique of desirably controlling dry strength to dry a coating solution of a slurry state coated on a base material. A drying device (3A) dries the coating solution (41) of the slurry state coated on one main side (51) of the base material (5) continuously transferred. The drying device (3A) includes: heating units (a coating side heating unit (35) and a rear side heating unit (37)) heating the coating solution (41); an emission pyrometer (39) measuring the temperature of an unchangeable emission rate part (531) on the other main side (53) in which an emission rate is not changed due to heating in the base material (5), at a position of the lower side of a transfer direction than the heating unit; and a heating control unit (711) controlling the strength of the heating by the heating unit based on temperature measured by the emission pyrometer (39).

Description

technical field [0001] The present invention relates to a technique for drying a slurry-like coating liquid. Background technique [0002] Patent Document 1 discloses that the temperature of a coating film on a base material is measured at a plurality of positions by a temperature measuring unit including a radiation thermometer or thermography. In addition, it is disclosed that the drying strength of the drying nozzle on the downstream side is made higher than the drying strength of the drying nozzle on the upstream side based on the measurement results of each temperature measuring unit. [0003] In addition, Patent Document 2 discloses that in order to improve the adhesive force of the coating film to the base material, the base material is heated with a heating unit from the side of the base material surface not coated with the coating film, and the base material is heated with a cooling unit through the base material side. The material cools the upper surface of the co...
