The piece 42 can be moved closer to or away from the other flattening member 42 along the adjustment direction 52, thereby adjusting the distance d2 between the axes of the leveling members 42 to match the substrate 6 or the ink layer 7 of different thicknesses. It is ensured that the entire plane 421 of the leveling members 42 is reliably resisted to level the surface of the ink layer 7.

Referring to Figures 1, 4, 8, and 9, it is further illustrated that the scraping mechanism 4 of the present embodiment can achieve scraping on the setting surface as long as the forming member 41 and the scraping adjusting unit 43 are included. The ink material 8 on 61 is used for the purpose of forming the ink layer 7, and at this time, the number of the blade adjusting units 43 may be one or several to match the number of the forming members 41. However, the scraping mechanism 4 of the present embodiment can level the surface of the ink layer 7 through the flattening members 42, thereby improving the quality of the product. Of course, in practice, the scraping mechanism 4 does not include the flattening members 42. As necessary.

Referring to FIG. 1, it should be noted that the pin wheel pushing member 241, the moving pushing member 391 and the scraping pushing member 46 of the embodiment are all in the form of a pneumatic cylinder. Of course, in practice, the pin wheel pushing member 241, the The moving pusher 391 and the scraper pushers 46 may also be in the form of a hydraulic cylinder or an empty hydraulic cylinder. In addition, in this embodiment, the conveying roller 21, the clamping rollers 23, the forming members 41 and the flattening members 42 are driven to rotate by a plurality of driving members, not shown, such as the driving members. The servo motor, the technique of driving the rotation of the aforementioned members, is not the focus of the present invention and will not be described.

Referring to Figures 1, 4, and 10, in use, the coating mechanism 3 of the present embodiment can be switched between a double-coated state as shown in Figure 1 and a single-coated state as shown in Figure 10. When the coating mechanism 3 is in the double-coated state shown in FIG. 1, the liquid level 81 of the ink material 8 in the two carriers 31 is higher than the top edge 322 of the abutting wall 321 . The coating mechanism 3 can simultaneously apply the ink material 8 on the two setting faces 61 of the substrate 6. When the coating mechanism 3 is in the one-side coating state shown in FIG. 10, only the liquid surface 81 of the ink material 8 in one of the carrier seats 31 is higher than the top edge 322 of the carrier wall 31 against the wall 321 . The other carrier 31 does not contain the ink material 8, or the liquid surface 81 of the ink material 8 is lower than the top edge 322 of the bearing block 31 against the wall 321 . At this time, the coating mechanism 3 is only on the substrate. The ink material 8 is coated on one of the setting faces 61 of 6. Therefore, in this embodiment, the ink layer 7 can be formed on the opposite side of the substrate 6 at the same time, or the ink layer 7 can be formed only on one side of the substrate 6, which is convenient and convenient to use, and can also reduce the equipment cost. .

Referring to FIGS. 1, 2, 3, and 4, further, after the coating mechanism 3 is coated on the substrate 6 with the ink layer 7, the ink layer 7 is viscous because it has not been subjected to baking and drying treatment, and this embodiment will The clamping roller 23 is designed as a dumbbell-shaped structure, so that the connecting rod portions 232 of the clamping rollers 23 are respectively spaced from the coating regions 612 of the setting surfaces 61, and the concave spaces of the clamping rollers 23 are 234, respectively, is provided for the ink layer 7 to pass through without contacting the connecting rod portions 232. Through the foregoing innovative structural design, the ink layer 7 can be prevented from being touched by the clamping rollers 23, so that the ink layer 7 can be maintained in the scraping material. The optimum structure and quality of the scraping and finishing of the mechanism 4, along with the substrate 6 Moving along the line direction 51 into the oven apparatus 9, the ink layer 7 is baked through the oven apparatus 9 to dry and solidify.

In addition, the clamping rollers 23 are respectively located on opposite sides of the substrate 6, and the abutting end portions 231 are respectively clamped to the positioning regions 611 of the setting surface 61 of the substrate 6 in pairs. In addition to the substrate 6 being transported away from the coating mechanism 3, the clamping and transporting unit 22 can stably support the substrate 6 and level the substrate 6, so that the scraping mechanism 4 The forming member 41 can firmly scrape the ink material 8 coated on the substrate 6 to form the ink layer 7 having a desired thickness, and the leveling member 42 of the scraping mechanism 4 can also stably level the ink layer 7. surface. Therefore, the thickness of the ink layer 7 obtained by the blade coating apparatus of the present embodiment is uniform, thereby improving the manufacturing precision and the manufacturing yield of the blade coating apparatus, and reducing the production cost.

More importantly, the tank for accommodating the ink material has a larger capacity than the coating method in which the entire substrate is generally dip-coated in the ink material, so that the member can be mounted in the tank to transport the substrate. In turn, the tank body often contains a large amount of ink material. Further, since the organic solvent in the ink material is easily volatilized, in the manufacturing process of the above-described method, the organic solvent is excessively volatilized, and the ink material is too thick to be used. In this case, the entire ink material needs to be replaced, thereby increasing the manufacturing cost. In contrast, the carrier 31 of the present invention has a simple structure, and the receiving groove 33 of each of the carriers 31 is only used for accommodating the ink material 8 and does not need to accommodate other components, so the volume thereof is small, so that only a small amount and a large amount are required. Subsequent replenishment of the ink material 8 can avoid the problem that the organic solvent is excessively volatilized and the ink material 8 cannot be used, thereby reducing unnecessary consumption and waste of the material.

In summary, the coating mechanism 3 of the present invention is divided into two carriers 31 which are closely sandwiched on opposite sides of the substrate 6, and are located between the carriers 31 and are available for the substrate 6 to pass through. Through the aforementioned innovative structural design, the above-mentioned innovative material space 35 enables the present invention to simultaneously have the functions of single-sided coating and double-side coating, and has wide applicability and convenient use, and can also reduce equipment cost. Further, the substrate 6 can be stably supported and flattened by the pinch conveying units 22, whereby the forming member 41 of the scraping mechanism 4 can stably scrape the ink material 8 coated on the substrate 6. In order to form the ink layer 7 having a desired thickness, the flattening member 42 of the scraping mechanism 4 can also level the surface of the ink layer 7, and then the holding roller 23 does not touch the ink layer 7, so the ink layer 7 The structure and quality can be maintained at the optimum state as expected, thereby improving the manufacturing precision and manufacturing yield of the present invention, and reducing the production cost.

The above is only the preferred embodiment of the present invention, and the scope of the present invention is not limited thereto, that is, the simple equivalent changes and modifications made by the patent application scope and patent specification content of the present invention, All remain within the scope of the invention patent.
