Description of the invention: [Related application] This application claims priority based on Japanese Patent Application No. 2 _ 6 337 685. [Technical Field of the Invention] The present invention relates to a coating die for providing a slit-like outlet for supplying a coating liquid to relatively move an object to be coated, and to supply a coating liquid from the upper to the outlet. In particular, the coating apparatus on the surface of the coating material has such a feature that the high-viscosity coating liquid can be applied to the surface of the object to be coated in a thin, smooth, and even manner even when a high-viscosity coating liquid is used. [Prior Art] In the past, when manufacturing a plasma display panel or an organic electroluminescence (ELECTROluminescence) display panel, a liquid crystal display panel, etc., various coating objects such as a glass substrate, a resin film, and a metal squeegee were applied to the surface. The coating device is coated with various coating liquids. Further, in the case of such a coating apparatus, for example, as shown in Fig. 1, a coating die 1 which is provided with a crack-like outflow D^ at the tip end is provided in the self-formed coating object i The coating die 1〇 is moved relative to the object 1 by the position of the gap gp at a desired interval, and the coating liquid 2 is supplied from the slit Δ of the coating die 10 to the above. The surface of the W is applied to the object to be coated! The surface is coated with a coating liquid 2 . In addition, in recent years, when coating the coating liquid 2 319276 5 丄 to 2717 on the surface of the object 1 to be coated as described above, in order to reduce the cost of the coating liquid 2 and the like, "the coating liquid 2 is contained therein." The method of reducing the thickness of the coating liquid 2 applied to the surface of the object 1 to be coated while reducing the amount of the solvent. Here, if the amount of the solvent contained in the coating liquid 2 is reduced as described above, the viscosity of the coating liquid 2 is increased. In order to accelerate the application speed of the coating mold ί as described above, the coating liquid 2 having a high viscosity is applied to the surface of the object to be coated i as described above, and the coating liquid 2 supplied to the surface of the object to be coated is coated. The dragging device 10 is dragged, so that there is a problem that the coating is uneven, or the coating liquid is interrupted, etc. In addition, in order to suppress the coating unevenness and the coating liquid interruption as described above, the surface of the mold 10 and the object 1 to be coated are used. In the gap Gp, as shown in Fig. 2, the coating liquid 2 supplied from the outlet ii to the surface of the object to be coated is transferred to the side opposite to the moving direction of the coating die 1 to be coated. To the coated object! Surface On the other hand, the surface of the coating liquid 2 coated on the surface of the object to be coated i has a problem of unevenness. 1 Further, in recent years, the coating liquid is applied from a coating die as described above to a fully supported roller (backupr〇11). When arranging a mobile web (web) to form a coated object, as disclosed in Japanese Patent Laid-Open Publication No. 2003-236434, it is proposed to have a coating consisting of a net relative to the above-mentioned coating die: A decompression chamber is provided on the upstream side, and a pressure-reducing portion of the coating liquid from the coating mold to the coating material supply upper side is subjected to a pressure-reducing portion to control the heel portion of the coating liquid supplied to the object to be coated. In addition, as shown in Fig. 3, the house reduction chamber 3 is provided on the side of the moving mold 319276 6 U22111 in the moving direction of the coating die 1〇, and the adjustment valve h is passed through the face chamber 3 via the adjustment valve h. The pump 3b (4) is lowered to a predetermined dust force, and the downstream side portion of the coating liquid 2 is supplied from the coating die 1 () to the surface of the object to be coated in a reduced pressure state, and the lower edge of the chamber 3 and the object to be coated are reduced. 】The gap between the surfaces becomes larger, and the outside air is transmitted through. This interval flows into the decompression chamber 3, and the angling method is supplied, and the downstream side portion of the coating liquid 2 on the surface of the coating material i is reduced, in particular, the coating of high viscosity is as described above. When the liquid 2 is thinly applied to the surface of the object 1 to be coated, there is a problem that coating unevenness occurs. On the other hand, in order to suppress the passage of outside air through the gap between the lower edge of the decompression chamber 3 and the surface of the object to be coated 1, The inside of the decompression chamber 3 is contacted with the object to be coated by the vibration of the coating die 或 or the unevenness of the surface of the object 1 to be coated, etc. [Problems to be Solved by the Invention] The present invention is to solve the problem of providing a slit-like outlet for supplying a coating liquid at a tip end. The problem as described above in the coating apparatus in which the coating material is relatively moved by the mold and the coating liquid is supplied from the above-mentioned outlet to the surface of the object to be coated is a subject. In other words, in the present invention, even when a high-viscosity coating liquid is used, the high-viscosity coating liquid can be applied thinly, smoothly, and evenly onto the surface of the object to be coated. (Means for Solving the Problem) In the present invention, in order to solve the problem as described above, a coating 319276 7 1322717 is provided, which is used to provide a coating liquid for supplying a coating liquid: In the above-mentioned = = cloth liquid to the surface of the object to be coated, in the vicinity of the position where the cloth liquid is supplied from the above-mentioned outlet port to the object to be coated, a gas nozzle for ejecting the gas toward the downstream side in the moving direction of the coating crucible is provided.

The machine outlet of the machine is removed from the surface of the object to be coated with the coating liquid, and the air in the downstream side of the moving direction of the coating die is dragged on average in the entire length of the outlet of the coating die. A uniform φ reduction state is presented. As a result, the coating liquid is supplied to the surface of the object to be coated in a relatively uniform state, and the coating liquid is applied to the surface of the object to be coated more uniformly, and such a high viscosity can be applied even in the case of using a yttrium-coating liquid. The liquid is thin and the vehicle is smoothly and uniformly applied to the surface of the object to be coated. In addition, when the gas ejecting apparatus is inclined to the downstream side in the moving direction of the coating die and the gas is ejected from the gas ejecting apparatus as described above, it is inclined to be coated when it is ejected from the vertical direction of the object to be coated. The downstream side of the moving direction of the mold is at 10. To 70.

Here, the coating liquid 2 is supplied from the slit-like outlet port 11 at the tip end of the coating die 10 to the surface of the object 1 to be coated, and when the coating liquid 2 is applied to the surface of the object 1 to be coated, for example, the viscosity is made. l When the high-viscosity coating liquid 2 of the cps degree is applied to the surface of the object to be coated to a predetermined film thickness d in the range of 1 〇 to 3 〇 #m, in the past, if the coating die 1 tip is applied When the gap Gp between the slit-shaped outlet port 1 and the surface of the object to be coated becomes large, the coating liquid 2 supplied from the outlet port j丨 to the surface of the object to be coated is as shown in FIG. 2 In the state of being transferred to the side opposite to the moving direction of the coating die 1Q, the surface of the coating liquid 2 applied to the surface of the object to be coated i is unevenly formed, and the high-viscosity coating liquid 2 as described above is thinly applied to the surface. There is difficulty in the surface of the object 1 to be coated. In contrast to the coating apparatus shown in the above-described embodiment, when the gas discharge port 23a having the crack shape at the tip end of the private gas nozzle 23 is inclined to the downstream side in the coating direction to discharge the high-pressure gas, even the force cloth is The gap Gp of the 10th-end crack-like outlet surface is set at (10)p/= 319276 12 with respect to the predetermined thickness d. The coating unevenness and the coating liquid are not interrupted, and the (four) degree coating liquid can also be used. 2 Thin, smooth and evenly applied to the object to be coated! Surface. In the coating apparatus of the above-described embodiment, the coating die is moved relative to the object to be coated i. However, it is also possible to fix the coating die to move the object 1 to be coated. • , I. Although the month has been fully explained in the form of Λ &, but the letter has a knowledge of the technology in the private sector, you can clearly understand the changes and modifications. Accordingly, such changes and modifications are intended to be included within the scope of the invention.
