The present invention relates to a method for manufacturing a display member. The present invention relates to a method for manufacturing characters, symbols, pictures, and marks in three-dimensional shapes to be applied to a dial, parting board, day wheel, date wheel, etc. on a substrate of a display member for a watch, such as a display member for a watch. We offer a wide variety of designs that cannot be achieved with other methods, and we offer them at rock-bottom costs. A typical example of current display materials that have letters, symbols, and marks made in three dimensions is the dial. Since the dial of a watch is the face of the watch, it is required to have excellent design as well as function, and since it is one of the most expensive parts of a watch, it is important to find a dial with an excellent design at a rock-bottom price. The question of how to make them is becoming an important issue. First, the biggest problem with current watch dials from the perspective of reducing costs is the typesetting process for letters and marks. The current typesetting process for dials typically places 11 or 12 typesettings on the finished dial base plate.
Many individual letters are placed by hand, which requires a large amount of man-hours as it cannot be mechanized or automated. The reason why it is not possible to mechanize or automate the typesetting process for letters and marks is that there are many types of letters and they have complex shapes, making it difficult to align them, and when letters come into contact with each other, they get scratched and have a poor appearance. This is because automatic feeding of characters is very difficult to store. The current dial manufacturing method will be explained in more detail, focusing on the typesetting process. First, the current method of manufacturing characters will be described. Press the surface of the brass plate with a press to form the letter feet and letter parts. Figure 1-1, 4 Next, punch out the letter parts using a press. Figure 1-
2,5 Next, the letter 1 punched out with a press is barrel polished to remove any burrs from the press punch. Next, apply a Ni undercoat. Next, the upper surface of the letter is cut with diamonds and finished with plating to complete letter 1. Figure 1-3, 6 In addition, marks and window frames are processed in roughly the same way as for letters. Next, a process of typesetting the completed characters 1 onto the completed dial base board 2 will be explained. First, grab the hand-completed character 1 with tweezers and insert it into the character hole of the completed dial base plate 2.
Insert the letter feet and plant the letters. Next, manually pour adhesive from the back side of the completed dial base plate 2 into the character holes of the dial base plate.
A character 1 is fixed to a completed dial base plate 2. Figure 2 The typesetting process for marks and window frames is done in the same way as the typesetting process for letters. As mentioned above, the work of manually inserting characters is
Typesetting of characters is difficult due to the fact that a large number of characters, at least 11, must be placed on one dial plate, and the width and thickness of characters have become smaller as designs have diversified recently. The process is extremely time consuming and the work involved is extremely demanding. As described above, the present invention aims to eliminate the complexity of the current work of forming, for example, letters on a dial into a three-dimensional shape, and to further expand the variety of designs. That is, the present invention involves forming letters, symbols, pictures, marks, etc. on display members such as dials, parting boards, day wheels, date wheels, etc. into three-dimensional shapes using photosensitive resin using photosensitive resin. A method of manufacturing a display member is provided. The method for manufacturing a display member of the present invention will be explained in detail. That is, the present invention provides for a timepiece member such as a dial, parting board, day wheel, date wheel, etc., which has three-dimensional characters, symbols, pictures, marks, etc. of different heights on the substrate of the display member. A method for manufacturing a display member, characterized in that symbols, patterns, and marks are sequentially formed in a three-dimensional shape from the lowest height using a photosensitive resin using a photographic technique. The method for manufacturing a display member of the present invention will be explained in detail. For example, if the display member has different heights or different thicknesses on the substrate,
For display members such as dials, parting boards, day wheels, and date wheels that have three-dimensional letters, symbols, patterns, and marks of 0.2 mm and 0.4 mm, first, the height of The thickness of the lower side is 0.2mmt
Characters, symbols, patterns, and marks are formed using photosensitive resin using photographic technology. That is, a photosensitive resin monomer is coated to a thickness of 0.2 mm on the substrate of the display member (for example, a metal plate or a thin plastic film), and a 10μ thin transparent film is placed on top of it.
Furthermore, a mask with the necessary characters, symbols, pictures, and marks in white is placed on top of that, and when ultraviolet rays are irradiated from the mask side, the areas irradiated with ultraviolet rays photopolymerize and become photosensitive resin polymers. Become,
Three-dimensional letters, symbols, and designs with a thickness of 0.2 mm,
Marks are formed. Next, the mask and 10μ thin transparent film are removed, and the entire surface of the display member substrate (e.g. metal plate, thin plastic film) on which characters, symbols, pictures, and marks with a thickness of 0.2 mm have been formed is again photosensitive. Apply resin monomer to a thickness of 0.4mm, place a 10μ thin transparent film on top of it, and then overlay a mask with the necessary characters, symbols, patterns, and marks in white on top of it. When UV rays are irradiated from the side, the irradiated area undergoes photopolymerization and becomes a photosensitive resin polymer, increasing its thickness.
Three-dimensional letters, symbols, patterns, and marks of 0.4 mm thickness are formed. Finally, when the photosensitive resin monomer that is not irradiated with ultraviolet rays is developed and removed, three-dimensional characters, symbols, patterns, and marks of different heights are formed on the substrate of the display member (e.g., metal plate, thin plastic film). Ru. Characters of different heights on the board of the above display member,
Highlighting the features of the manufacturing method of the present invention for forming symbols, designs, and marks in three-dimensional shapes, firstly, the shapes of characters, symbols, and marks are determined by a mask, so free designs can be made; Graphic designs are also possible. Moreover, it can be easily drawn using automatic drafting (CAD). Second, since the basic technology of the manufacturing method of the present invention is photographic technology, it is easy to perform batch processing and continuous processing using hoops that can process many parts at once, and it is easy to mechanize and automate, so the manufacturing cost is reduced. is very cheap. Particularly in the case of dials, the cost reduction effect is very significant. In other words, the process of typesetting the characters is completely eliminated, and in the conventional method, 11 or 12 characters were individually machined and typesetting per dial plate, but in the case of the present invention, at least
This is because 11 or 12 characters can be created at once. As described above, the method for manufacturing a display member of the present invention includes:
For example, it is clear that this method brings about innovation in dial manufacturing in terms of design variety and cost compared to conventional methods that mainly involve machining of dials. Furthermore, other display members other than the dial, such as letters, symbols, pictures, marks, etc. on parting boards, day wheels, date wheels, etc., are currently used in flat shapes using printing methods. By using the method for manufacturing a timepiece display member of the present invention, a three-dimensional display member can be produced at a low cost, making it possible to further increase the commercial value. The method for manufacturing a display member of the present invention will be described in more detail based on an example in which the display member is a dial. Example 1 First, a transparent adhesive layer 3 is applied to a thickness of about 10 μm on a dial base plate 2 on which a surface pattern has already been applied. FIG. 3-1 Next, a photosensitive resin monomer 4 is dropped thereon and flattened with a squeegee to form a photosensitive resin monomer layer 4 having a thickness of about 200 μm. Furthermore, a transparent plastic film (PET) 6 with a thickness of 10 μm and a mask 7 with white alphanumeric characters are set on top of it. FIG. 3-2 In this case, it is important to ensure that no air exists between the photosensitive resin layer filled between the transparent plastic film 6 and the adhesive layer 3. As the above-mentioned solvent-free photosensitive resin monomer, commercially available photosensitive resins for letterpress printing such as Asahi Kasei's APR and Teijin's Tevista can be used. Next, when UV (ultraviolet light) is irradiated from the mask side, only the white part of the mask 7 is transmitted, and the photosensitive resin monomer 4 is cured by photopolymerization, resulting in a three-dimensional alpha abet with a thickness of 0.2 mm. Characters are formed from photosensitive resin 5. Figure 3-3 When Asahi Kasei's APR photosensitive resin is used, it is sufficiently cured in 60 seconds at an ultraviolet intensity of 5 mmW/cm 2 . Next, after irradiating ultraviolet rays, the 10μ plastic film (PET) and mask 7 are removed, and the thickness is 0.2
Drop the photosensitive resin monomer 4 again onto the entire surface of the dial base plate on which the three-dimensional alpha abet letters mmt are formed using the photosensitive resin 5, and flatten it with a squeegee to form a photosensitive resin monomer layer 4 with a thickness of 400μ.
form. Furthermore, a transparent plastic film (PET) 6 with a thickness of 10 μm and a mask 7 with white arithmetic numeric characters are set on top of this. Figure 3-4 Next, when ultraviolet rays are irradiated from the mask 7 side, the ultraviolet rays are transmitted only to the white areas of the mask 7,
The photosensitive resin monomer 4 is cured by photopolymerization and the thickness is increased.
Three-dimensional arithmetic numeric characters with a thickness of 0.4 mm are formed of photosensitive resin 5. Figure 3-5 Next, when the 10μ plastic film 6 and mask 7 are removed and the photosensitive resin monomer 4 is dissolved in a developer, thicknesses with different heights are formed on the dial base plate 2.
Alphabetic characters with a thickness of 0.2 mm and arithmetic numeric characters with a thickness of 0.4 mm are formed. Figure 3-6 Developer solution when using Asahi Kasei APR

It's a minute. Next, an ink layer 8 of a desired color tone is formed by a printing method only on the portions of the plastic characters 5 that have been formed, thereby completing a dial plate produced by the display member manufacturing method of the present invention. Figure 3-7 Example 2 Adhesive layer 3 on metal or plastic film 9
Apply to a thickness of approximately 10μ. FIG. 4-1 Next, a photosensitive resin monomer 4 is dropped thereon and flattened with a squeegee to form a photosensitive resin monomer layer 4 having a thickness of about 150 μm. Furthermore, a transparent plastic film (PET) 6 with a thickness of 10 μm and a mask 7 with white marks are set on top of it. FIG. 4-2 In this case, it is important that no air exists between the photosensitive resin polymer filled between the transparent plastic film 6 and the adhesive layer 3. As the above-mentioned solvent-free photosensitive resin monomer, commercially available photosensitive resins such as Asahi Kasei's APR photosensitive resin for letterpress printing and Teijin's Tevista photosensitive resin can be used. Next, when UV rays are irradiated from the mask side, only the white portions of the mask 7 are exposed, and the photosensitive resin monomer 4 is cured by photopolymerization, resulting in a thickness of 0.15 mm.
A three-dimensional mark of mmt is formed of photosensitive resin. Figure 4-3 When Asahi Kasei's APR photosensitive resin is used, it is sufficiently cured in 60 seconds at an ultraviolet intensity of 5 mmW/cm 2 . Next, after irradiating ultraviolet rays, the 10μ plastic film (PET) and mask 7 are removed, and the thickness is 0.15μ.
The photosensitive resin monomer 4 is again dropped onto the entire surface of the metal or plastic film 9 on which the three-dimensional mark of mmt is formed using a photosensitive resin, and the photosensitive resin monomer layer 4 is flattened with a squeegee to form a photosensitive resin monomer layer 4 with a thickness of 300μ. Form. Furthermore, a transparent plastic film (PET) 6 with a thickness of 10 μm and a mask 7 with white Arabic numeral characters are set on top of that. Figure 4-4 Next, when ultraviolet rays are irradiated from the mask side, the ultraviolet rays are transmitted only to the white areas of the mask 7, and the photosensitive resin monomer 4 is cured by photopolymerization, increasing the thickness.
Three-dimensional Arabic numeral characters of 30 μt are formed from photosensitive resin 5. Figure 4-5 Next, the 10 μm plastic film 6 and the mask 7 are peeled off, and when the photosensitive resin monomer 4 is dissolved in a developer, marks of 150 μt thickness and different heights are formed on the metal or plastic film 9. 300μt Arabic numeral characters are formed. FIG. 4-6 Next, the entire surface of the metal or plastic film 9 on which the three-dimensional letters and marks of different heights are formed is coated with lacquer 10 in a desired color. Figure 4-7 If the thickness of the coating 10 is kept within 10μ, even the convex parts can be coated almost uniformly. Next, an ink layer 8 of a desired color tone is formed only on the portions of the formed plastic characters 5 by a printing method.
FIG. 4-8 Finally, the metal or plastic film 9 described above is pasted onto the dial base plate 2 via the adhesive layer to complete the dial plate produced by the display member manufacturing method of the present invention. Figure 4-9 The above embodiment is for a dial plate, but other display members such as parting plates, day wheels, date wheels, etc. can also be used in three-dimensional shapes with different heights in the same way as for dial plates. It is possible to form characters, symbols, patterns, and marks. In addition, the above embodiment deals with the case where characters, symbols, pictures, marks, etc. of two different heights are formed, but even if there are three or more heights, the height can be increased by sequentially forming from the one with the smallest thickness. It is possible to form three or more types of characters, symbols, patterns, and marks. As is clear from the embodiments of the dial plate described above, the method for manufacturing the display member of the present invention eliminates the typesetting process in the conventional dial plate manufacturing process, and also allows character formation to be performed at once using photographic technology. It can do a lot of things, it can be easily mechanized and automated, and it is relatively easy to perform batch processing and continuous processing using hoops, which brings about innovation in dial manufacturing compared to conventional methods that mainly involve mechanical processing. be. In addition, in terms of design, the formation of three-dimensional shapes of letters, symbols, designs, and marks can be determined by the mask, allowing for free designs and expanding the variety of designs. In addition, three-dimensional characters, symbols, patterns, and marks can be formed on display members other than dial plates, such as parting boards, day wheels, and date wheels at low cost, which is extremely useful for increasing the commercial value of the display members. It has an effect.
