Problems solved by technology

However, when the thinner coating film is used to manufacture green sheets of multilayer ceramic capacitors, this difference becomes conspicuous, so it becomes difficult to distinguish the specifications of the coating film according to the thickness of the film.

[0067] The following will refer to Figure 1 to Figure 7 Embodiments of the present invention will be discussed, but the present invention is not limited thereto.

[0068] Regarding the casting coating type coating device (first casting coating type coating device) and coating method according to the present invention, when it is assumed that the reference plane includes the rotation axis of the back-up roll and is along the When the projection direction is formed, the positional relationship between the casting and the back-up roll is adjusted so that the downstream projection can be projected to some extent from the reference plane.

[0069] In the following discussion, the protruding direction of the discharge port, that is, the axial direction of the backup roll, is referred to as the "width direction", and the direction perpendicular to the width direction, that is, the direction of the coated film formed by the rotation of the backup roll The direction, as discussed bel...

[0113] The following will refer to Figure 8 Let's discuss another embodiment according to the present invention. However, the present invention is not limited to the Examples. For convenience of discussion, components having functions as components used in the first embodiment are denoted by the same reference numerals, and explanations thereof are omitted.

[0114] Regarding the first cast coating type coating apparatus of the first embodiment, the coating film that has been formed on the surface of the material to be coated is continuously rotated in accordance with the rotation of the backup roll. However, the present invention is not limited thereto, and may be applied to a cast coating type coating device that does not use a coating material. The cast coating type coating apparatus which does not use a coating material is called the 2nd cast coating type coating apparatus of this invention.

[0133] Another embodiment according to the present invention will refer to Figure 9 to discuss. The present invention is not limited to this example. To simplify the discussion, components having functions as components used in the first embodiment are denoted by the same reference numerals, and explanations thereof are omitted.

[0134] In the first or second embodiment, the coating device for forming the coating film has been discussed. However, the present invention is not limited to this type of coating device, and can be better applied to a manufacturing device of a sheet-like member (manufacturing machine of a sheet-like member), which can be used to manufacture a sheet formed of a coated film. shape components.

[0135] In particular, for example, in Figure 9 As shown in (a), there is provided a first sheet member manufacturing apparatus according to this embodiment including: the first cast coating type coating apparatus (coating apparatus) 20a discussed in the f...

Abstract

The present invention discloses a casting coating type coating device and coating method, assuming that the reference plane passes through the rotation shaft 31 of the backup roll 3 and is formed along the convex direction of the downstream convex portion 21a constituting the discharge port 24 . At this time, the setting of the spray casting 2 and the backup roll 3 is determined so that when the thickness of the downstream convex portion 21a is marked as L, and the amount of protrusion is the distance between the above-mentioned reference plane 7 and the downstream edge P0 of the downstream convex portion 21a When the interval is marked as X, there is a relationship between the thickness L and the protrusion amount X: 0.25<X / L≦0.5. In such an apparatus and method, even when the mechanical accuracy of the coating gap varies, the resulting variation in film thickness of the coating film can be reduced, and a thinner coating film can be supported.

Description

technical field [0001] The present invention relates to a casting coating type coating device and a coating method, which uses a casting having a slit-shaped discharge port to continuously coat a liquid coating agent on a surface to be coated provided by a roller, and also It relates to a manufacturing device for sheet-like components. In particular, the present invention relates to a casting coating type coating apparatus and coating method suitable for forming green sheets of ceramic materials in the manufacture of ceramic capacitors, multilayer substrates, etc., and to a sheet member manufacturing apparatus. Background technique [0002] Heretofore, among ceramic capacitors, especially multilayer ceramic capacitors, they have been widely used in various electronic devices due to their characteristics such as compact structure, large capacity, and high reliability. [0003] This multilayer ceramic capacitor is a capacitor in which a thin dielectric ceramic layer is stacke...
