Problems solved by technology

Therefore, there is a risk that the drying nozzles on the upstream side continue to perform inappropriate drying processes
[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 invention provides a technology, which can properly control the drying strength of a coating liquid painted on a substrate. A drying device (3A) dries a slurry like coating liquid (41), which is painted on the main surface (51) of a continuously delivered substrate (51). The drying device (3A) comprises a heating part, which comprises a coated side heating part (35) and a back side heating part (37) and is used to carry out a heating treatment on the coating liquid (41); a radiation temperature meter (39), which is arranged on the downstream side along the delivering direction of the heating part and is used to measure the temperature of a part (531) on the main surface (53) in the other side, wherein the radiation rate of the substrate (5) will not be changed by the hot treatment; and a heating control part (711), which is used to control the strength of the heat treatment preformed by the heating part according to the temperature measured by the radiation temperature meter (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 measurement 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 ...
