る。The present invention provides a method for manufacturing watch hands for use in analog display watches by press working and photo etching. Since it is not completely masked, it has the disadvantage of being corroded by etching, so by using a peel-off type synthetic resin agent as a new masking for the masking part, it is possible to prevent corrosion due to etching and also to remove the outline of the needle by etching. This prevents it from falling off during processing.

を製造する。The conventional manufacturing method for watch hands is mainly by pressing, but the press-based processing method requires a lot of time to make the mold, making the mold expensive, and the shape There were also drawbacks such as restrictions on pattern formation and the inability to respond to diversification of designs.
The needles are manufactured using press processing and photo-etching. An example of the conventional method is shown in FIG.
Shown in l~(d). First, attach Hakama 2 to the metal strip l.
After forming by press working (FIG. 2(a)), dry film resist 4 is applied to both sides of the strip material 1, as shown in FIG. 2(b).
1), an image of the pattern 7 and the outline 8 of the needle as shown in FIG. 2(e) is formed by exposure and development, and then the pattern 7 is formed by etching as shown in FIG. The outer shape 8 is cut out and the dry film resist 4 is peeled off to manufacture clock hands.

ている。Other embodiments of the conventional method are shown in FIGS. 3(a) to 3(d). First, as shown in Fig. 3(a), a photoresist 14 is applied to a metal strip 1, and by exposure and development, an image of the center hole 12 and outer shape 8 of the needle as shown in Fig. 3-) is formed. Then, as shown in Figure 3(d), the center hole 12 and outer shape 8 of the needle are removed by etching to form the shape shown in Figure 3(d), and then the center hole 12 of the needle is etched. This is a method of press-fitting a vibrator to form a hook 2, and a method of removing the outer shape of a needle is disclosed in Japanese Patent Publication No. 62-5303.

生してしまい針の機能に支障となる欠点があった。However, according to the above-mentioned manufacturing method of press working and photoetching, it is not possible to mask the three-dimensional shape formed by the press working with the liquid photoresist used in the next photolithography process beyond the height of the hakama. A film resist was used, but when masking with a dry film resist, the method shown in Figure 4 (
Since a gap 10 is formed between the blade 90 and the area around the blade 90 as shown in FIG. There was a drawback that corrosion 11 occurred in the part, which hindered the function of the needle.

、機能上問題となっている。In addition, in order to avoid corrosion of the hakama 2 part during the etching process, a Suzuki center hole is formed during the etching process,
In the method of forming a hook by press-fitting a pipe, there are functional problems due to variations in the cross-sectional shape and dimensional accuracy of the central hole of the needle.

った。Furthermore, during etching to remove the outer shape of the needle, a bridge 13 is provided on a portion of the needle as shown in FIG. 5 to prevent the needle from falling off, but cutting the bridge 13 after etching is very time-consuming. Therefore, it takes a lot of time to manufacture the needle, which has the disadvantage of increasing the cost of the needle.

のである。In order to solve the above problems, the present invention provides a three-dimensional hakama part formed by press working on a metal band material,
In order to prevent the wing part from being corroded during later etching, first apply a dry film resist to the flat side opposite to the hakama side, and then apply a peel-off type synthetic resin agent to the hakama part and the hakama side to completely mask it. After this, a photomask is used on the flat side coated with dry film, and an image of the needle's outline and pattern is formed by exposure and development, and the needle is processed by single-sided etching. By improving the masking method for the three-dimensional shape, which is a three-dimensional shape, the masking method has been improved, and the shape and pattern, which are restricted in press processing, can be formed by press processing, and the masking method that poses a problem in terms of dimensional accuracy with photo-etching has been improved. By incorporating multi-processing, it is possible to respond to the diversification of designs, making it possible to manufacture a wide variety of needles with high added value.

易にし短納期で製造できるものである。As mentioned above, by applying a peel-off type synthetic resin agent to a level higher than the height of the 3D shape formed by press working on the metal band material, it is possible to remove the outer shape of the needle by etching. Since it is possible to prevent the etching solution from adhering to the hook part, the shape of the hook and blades is maintained.Furthermore, by using the synthetic resin agent of Hakritaibu as a support to prevent the needle from falling off, the needle can be etched using conventional photo-etching methods. The bridge that was applied in the manufacturing method to prevent the needle from falling off can be removed, eliminating the large amount of work involved in cutting the bridge, making it possible to manufacture high-value-added gauges with high quality, and making it easier and shorter to manufacture the needle. It can be manufactured on time.
