Description

Description: TECHNICAL FIELD The present invention relates to a method of manufacturing a display nameplate used for a knob or the like of a switch with transmitted illumination.

(Prior Art) Conventionally, as a method of manufacturing this type of display nameplate, for example, a technique disclosed in Japanese Utility Model Laid-Open No. 59-170882 is known.

In other words, in this technique, a mark portion made of an appropriate mark, symbol, or the like is formed by printing on a surface of a nameplate body made of a resin molded product with a printing ink to which a plating inhibitor is added, and the surface other than the mark portion is printed. A plating coating was applied.

(Problems to be Solved by the Invention) However, such a conventional manufacturing technique has the following problems.

a. The process is complicated because it requires a process using a plating tank.

b. It is necessary to select a material for the nameplate that does not deteriorate due to the plating solution.

c. Plating takes time. Low production capacity.

d. Since the opaque portion is formed by nickel plating or chromium plating, it is inappropriate if a metallic luster is not desired in design.

e. Since the printed layer that forms the shape portion and has the plating inhibition property remains in the finished product, it is necessary to consider the light transmission.

(Means for Solving the Problems) The present invention has been made in view of such a conventional problem, and it is possible to easily and easily form a light-transmitting image portion without plating treatment. It is an object of the present invention to provide a method for manufacturing a display nameplate.

In order to achieve this object, in the present invention, a first step of applying a semi-transparent first paint to a display surface of a nameplate body made of a transparent resin; A second step of printing a display image with an adhesive second paint, a third step of applying an opaque third paint to substantially the entire display surface, and applying the second paint together with a corresponding third paint portion; A method for manufacturing a display nameplate comprising a fourth step of peeling.

(Action) According to the method for manufacturing a display nameplate of the present invention, in the second step, the display image is printed with the non-adhesive second paint on the first paint applied in the first step. Further, in the third step, an opaque third paint is applied thereon, and finally, in the fourth step, the non-adhesive second paint is peeled off and the corresponding portion of the third paint is removed, whereby the display image is formed. Since the first paint surface is exposed in the form of (1), no plating treatment is required, and the restrictions imposed by the plating treatment can be eliminated.

(Embodiment) FIGS. 1 to 4 are explanatory views showing one embodiment of first to fourth steps relating to the manufacturing method of the present invention, taking a switch knob with transmitted illumination for an automobile as an example, and FIG. FIG. 6 is a perspective view of the switch knob formed through the four steps of FIGS. 4 to 4, FIG. 6 is a front view when the switch knob shown in FIG. 5 is incorporated in the switch main body, and FIG. It is AA sectional drawing.

First, a preferred embodiment of the present invention will be described with reference to FIGS.

First Step (FIG. 1) In the first step, the display surface 11 of the nameplate body 1 as a switch knob made of a transparent resin, for example, an acrylic resin.
, A semi-transparent first paint 2 is applied. As the first paint 2, for example, a white paint is used. In addition, the first paint 2
As the applying means, for example, means such as electrostatic coating or spray coating is used.

2nd process (FIG. 2) The application surface 21 of the first paint 2 applied in the first process of FIG.
A display image by a non-adhesive second paint 3, for example,
6 Print the hazard mark shown in Figure.

As the second paint 3, a silicon-based resin, a fluorinated resin, or a paint to which these are added, having a weak adhesive force to the first paint 2 applied in the first step, is used.

In addition, as a method of printing the second paint 3 on the application surface 21, a method such as so-called tampo printing that can print a display image accurately on the curved surface of the display surface 11 of the switch knob in this embodiment is used. . This tampo printing is a printing method of transferring a pattern printed on a backing sheet to a curved surface or an uneven portion by using a transfer head made of a material that can be deformed such as rubber or gelatin and does not absorb the transferred pattern. Are known.

Third step (FIG. 3) An opaque third paint 4, for example, a black paint, is applied to substantially the entire display surface 11 including the image portion of the third paint 3 printed in the second step of FIG. I do. The application of the third paint 4 uses means such as electrostatic painting or spray painting as in the first step of FIG.

Fourth step (FIG. 4) The second paint 3 applied in the second step of FIG. 2 is peeled off together with the corresponding portion of the third paint applied in the third step, and the second paint 3 is applied in the second step of FIG. The first paint 2 applied in the first step is exposed in the form of the printed display image. For example, as shown in FIG. 4, an adhesive tape 5
The second paint 3 having a weak adhesive force is applied to the first paint 2 of the nameplate body 1 by pressing the paint 4 on the coating surface of the paint 4 and then peeling it off.
Can be peeled off from the application surface 21.

By extracting the opaque third paint 4 such as black as shown in FIG. 4 and FIG. 5 by the first to fourth steps described above, a semi-transparent third paint such as white as a base is obtained. Switch knob 6 having a window 31 for exposing 1 paint 2
Can be manufactured.

The switch knob 6 manufactured as shown in FIG. 5 is assembled to the switch body 7 as shown in FIGS.

As shown in FIG. 7, the internal structure of the switch body 7 is a figurative window 31 formed on the display surface of the nameplate body 1 of the switch knob 6.
An illumination lamp 71 is provided for illuminating the illumination light from behind. By illuminating the illumination lamp 71, illumination light is transmitted through the figurative window 31 of the switch knob 6, and, for example, a hazard mark determined by the figurative window 31 from the outside is transparently displayed. be able to. Furthermore,
A sliding contact 72 and a terminal 73 are provided in the switch body 7.

In the above-described embodiment, the switch knob displaying the hazard mark is taken as an example. However, the present invention is not limited to this, and can be applied to an illumination nameplate that receives appropriate transmitted illumination. .

(Effects of the Invention) As described above, according to the method for manufacturing a nameplate for lighting of the present invention, many effects listed below can be obtained.

First, since a plating process is not required unlike the related art, a plating tank is not required, and the manufacturing process can be simplified.

Secondly, the material of the nameplate can be freely selected because the quality of the material does not change in the printing and coating processes.

Third, since a plating step is not required, it can be manufactured in a short time and a high production capacity can be obtained.

Fourth, the opaque portion can be colored with an appropriate color, and the design can be freely changed.

In FIG. 5, the shape window is formed as a recess by peeling off the non-adhesive second paint, and sufficient translucency can be obtained by exposing the semi-transparent first paint.

Sixth, the shape window can be easily formed even with a curved surface portion, and is suitable for an operation surface having various shapes such as a switch.

Seventh, the figurative window can be easily formed using an adhesive tape.
