Looking at the prior art with reference to the accompanying drawings as follows.

1 is a block diagram illustrating a method of manufacturing a metal plate with a pattern applied with a conventional technique, and FIG. 2 is a process diagram illustrating a method of manufacturing a metal plate with a pattern applied with a conventional technique.

In general, when the through-shaped pattern 11 designed as a pattern or a letter to transmit light to the metal plate 10 is formed, the through-type pattern 11 is formed of only the through-hole 12 penetrating up and down, or It consists of the through hole 12 and the piece 13 formed inside the through hole 12. For example, as shown in Figure 2, in the case of the English letters C, E, the through hole 12 is formed in the shape of a letter, but A , B, D is formed by the through hole 12 and the piece 13 located inside the through hole 12. By the way, in order for the piece 13 to be located inside the through hole 12, the piece 13 and the connection part (not shown) connected to the through hole 12 are required, which is different from the original pattern shape.

As a technology for solving this problem, the applicant has been granted a patent (10-0714377) as "Method for forming a pattern in which the connection is omitted, and a metal plate on which the pattern is omitted."

Looking at the method of manufacturing a metal flat plate with a pattern according to the prior art registered as follows.

The metal plate preparation step (S1) of cleaning the metal plate 10 to remove dirt, and the step of attaching the tape 20 to the lower surface of the metal plate 10 passed through the metal plate preparation step (S1) (S2) ), The step (S3) of applying or attaching a photosensitive material (50, a photosensitive aqueous film, a photosensitive resin film) on the metal flat plate (10), and a pattern printed on the photosensitive material (50) film 40 The film-adhering step (S4) in close contact with the film 40 and the photosensitive material 50 in contact with the transparent portion of the film 40 by irradiating natural light or ultraviolet rays to the upper portion of the film 40 is firmly changed, the black of the film 40 After the exposure photographing step (S5) and the exposure photographing step (S5) to prevent the photosensitive material 50 in contact with the portion, the film 40 is separated from the metal flat plate 10 and immersed in a developer solution for exposure photographing. The developing step (S6) of dissolving the photosensitive material (50) which is not changed by the step, and the developing step (S6). After hitting, a short etching process (S7) for removing foreign matter on the surface of the metal plate 10 with a thin etching solution, and the metal plate 10 subjected to the short etching process (S7) is immersed in a concentrated concentration of the etching solution Washing and peeling process (S9) and the washing and peeling process (S9) for removing the photosensitive material 50 attached to the metal plate 10 through the main etching process (S8) and the main etching process (S8) to allow the pattern to pass through The tape attaching step S10 for attaching the tape 30 to the upper surface of the metal flat plate 10 and the lower surface tape detachment step S11 for detaching the tape 20 of the lower surface of the metal flat plate 10. After the tape stripping step S11, the transparent sheet paper attaching step S12 for attaching the transparent sheet paper 15 to the bottom surface of the metal flat plate 10 and the transparent sheet paper 15 are separated, and then the metal sheet 10 is removed. It consists of an upper surface tape detachment process (S13) which isolate | separates the upper surface tape 30. FIG.

The metal flat plate 1 having the pattern formed by the manufacturing method may be formed of a transparent sheet paper attached to the metal flat plate 10, the through-shaped pattern 11 formed on the metal flat plate 10, and the bottom surface of the metal flat plate 10. 15), and the through pattern 11 is formed of a through hole 12 or a piece 13 positioned inside the through hole 12 and the through hole 12.

According to the above prior art, when the tape is attached several times and then detached, there is a problem that the process becomes complicated and the work is cumbersome.

In addition, during the short etching process and the main etching process, the tape attached to the lower surface of the metal plate is elongated by heat due to the generated heat, and after the short etching process and the main etching process, the tape is shrunk again at room temperature and completed. Since the transparent sheet is stretched by air or room temperature, the piece of the through pattern flows inside the through hole and loses its position. Therefore, the shape of the through pattern differs from the original shape. .

In the case where the metal plate is a thin plate having a thickness of 0.25 mm or less, transparent sheet paper is attached to the lower surface, but only by allowing the piece to be repositioned inside the through hole, the strength of the thin plate may not be reinforced. Therefore, it is easy to be wrinkled and damaged, and there is a problem that the unit price is increased by using a thick metal flat plate to reinforce the strength.

Accordingly, an object of the present invention is to provide a method of manufacturing a metal plate with a pattern and a metal plate with a pattern, which can solve the above problems.

In the method of manufacturing a patterned metal flat plate according to the present invention, the coating layer is formed by repeating a process of applying a transparent coating agent as a synthetic resin material to the bottom surface of the metal flat plate and drying it many times. The coating layer may be printed by dye, and the metal plate having the pattern formed by the manufacturing method may include a metal plate, a through-type pattern formed on the metal plate, and a transparent coating agent coated on the bottom surface of the metal plate as a synthetic resin material. It is intended to consist of a fixed coating layer.

The manufacturing method of the patterned metal flat plate and the patterned metal flat plate according to the present invention eliminate the cumbersome work of attaching and detaching a tape to the upper surface or the lower surface of the metal plate, thereby reducing the process and making the work easier. In the short etching and the main etching, the coating fixed by the generated heat is not extended or contracted after the short etching and the main etching, so that the piece flows out of position and does not occur. Even if it is not stretched and is provided with a thin plate of 0.25 mm or less in thickness, the coating layer is formed on the lower surface, thereby preventing the occurrence of damage such as wrinkles due to reinforcement of strength and thus, manufacturing cost. Is less, and the coating is printed with a dye, the light from the back can produce a variety of colors It has an effect.

Hereinafter, with reference to the accompanying drawings, look at the present invention for achieving the above object.
