Description

Manufacturing method of decorative parts

The present invention relates to a method for manufacturing a decorative part that is used in a state where a hydraulic transfer layer and a clear coat layer are formed on the surface of a part material having a three-dimensional shape and are arranged adjacent to each other.

Conventionally, in automobile interior parts, decorative parts (for example, console boxes, instrument panels, armrests, etc.) that add decoration to the surface of parts made of resin moldings to improve design and quality. Many have been put to practical use. As an effective method for adding decoration to a three-dimensional part such as an automobile interior part, for example, a hydraulic transfer method is well known.

Here, the hydraulic transfer method means that a water-swellable transfer film is floated on the water surface, and a predetermined pattern (for example, a pattern such as a wood grain pattern or a geometric pattern) formed on the transfer film is hydraulically transferred. This is a technique for transferring onto the surface of a component material, and is advantageous in that printing on a three-dimensional curved surface can be performed relatively easily. However, the printed layer transferred to the surface of the component material by the hydraulic transfer method is weaker than the coating film and is not sufficiently durable. Therefore, a clear coat layer is usually formed as a protective layer on the surface of the hydraulic transfer layer made of a printing layer.

Furthermore, in recent years, in order to improve the appearance quality of the decorative part, a technique has been proposed in which another pattern is formed in an auxiliary manner according to the main pattern (see, for example, Patent Document 1). Incidentally, Patent Document 1 discloses a method of forming a clear coat layer after imparting a main pattern by transfer of a hydraulic transfer layer, and performing laser processing on the clear coat layer based on data created by photographing the main pattern. It is disclosed. After this laser processing, an auxiliary pattern synchronized with the main pattern of the hydraulic transfer layer is formed on the clear coat layer, and the three-dimensional effect is increased.

JP 2011-126179 A

By the way, when it is desired to accentuate an auxiliary pattern having a pattern different from the main pattern in the decorative part, for example, hydraulic transfer is performed using a transfer film in which a printing layer including the main pattern and the auxiliary pattern is formed in advance. It is possible. However, since the hydraulic transfer is performed in a continuous production system using a roll-shaped transfer film during the production of conventional decorative parts, the pattern is not positioned, and the position of the pattern to be applied is left to success. The Accordingly, the position of the pattern varies from part to part, and the individual pattern itself is apt to be distorted. Therefore, even if the above-described method is adopted, it is difficult to accurately apply the auxiliary pattern to a desired position, and it is difficult to apply the auxiliary pattern that is fine and has no distortion. Furthermore, the main pattern and the auxiliary pattern cannot be sufficiently contrasted, and the auxiliary pattern is not so conspicuous. Therefore, it is difficult to obtain the merit by providing the auxiliary pattern, and the appearance quality of the decorative part cannot be improved.

Moreover, there are the following problems at the time of manufacturing a conventional decorative part by the hydraulic transfer method. That is, even when a plurality of decorative parts that have been given the same main pattern by the hydraulic transfer method are used adjacent to each other, the position of the main pattern does not match between the parts, You cannot get a sense of body and a sense of unity. Therefore, it has been difficult to give high appearance quality to a plurality of decorative parts having such an arrangement relationship.

In addition, the method described in Patent Document 1 is advantageous in terms of increasing the three-dimensional effect, but does not consider decorative parts that are used adjacent to each other. Rather, the pattern misalignment may even be emphasized. Therefore, even if this method is adopted, it is still impossible to obtain a sense of unity and unity of the design.

The present invention has been made in view of the above problems, and a first object thereof is a decorative part that can easily and accurately apply an auxiliary pattern that stands out from a main pattern to a desired position. It is in providing the manufacturing method of.

In addition, a second object of the present invention is to provide a method for manufacturing a decorative part that can sufficiently and relatively easily obtain a sense of unity and unity in design for parts used in a state of being arranged adjacent to each other. There is to do.

In order to solve the above problems, the invention described in means 1 is characterized in that a hydraulic transfer layer including an ink layer is formed on the surface of a three-dimensional component material, and a clear coat layer is formed on the hydraulic transfer layer. In the method for manufacturing a decorative part, a hydraulic transfer step of forming the hydraulic transfer layer including the ink layer for imparting a main pattern on the surface of the component material by a hydraulic transfer method, and the ink in the hydraulic transfer layer An auxiliary pattern forming step of forming a pattern with a different contrast from the main pattern and forming a high contrast auxiliary pattern compared to the main pattern by removing a part of the layer to a depth reaching the surface of the component material by laser processing; And a clear coat layer forming step of forming a clear coat layer on the hydraulic transfer layer on which the auxiliary pattern is formed.

Therefore, according to the invention described in the means 1, after the main pattern is provided on the surface of the component material by the hydraulic transfer process, the auxiliary pattern having a pattern different from the main pattern is formed by the auxiliary pattern forming process. Here, the auxiliary pattern is formed by removing a part of the ink layer to a depth that reaches the surface of the component material by laser processing, so the contrast is higher than the main pattern made of the ink layer, and the auxiliary pattern is higher than the main pattern. Can stand out. Further, according to laser processing, a fine auxiliary pattern excellent in shape can be relatively easily and accurately applied to a desired position.

The invention described in means 2 is characterized in that, in the auxiliary pattern forming step, in the decorative part used in a state of being arranged adjacent to each other, the auxiliary pattern is formed at a location including at least a part edge. The gist of the method for manufacturing a decorative part described in Means 1 is as follows.

Therefore, according to the invention described in the means 2, the adjoining parts are formed by forming the auxiliary pattern at the positions including the respective component edges in the adjoining decorative parts, for example, by giving the corresponding relationship to the mutual positions. The impression that the pattern matched between can be given. Therefore, it is possible to obtain a sense of unity and unity between adjacent parts sufficiently and relatively easily.

The gist of the invention described in means 3 is the method of manufacturing a decorative part according to means 2, characterized in that, in the auxiliary pattern forming step, the linear auxiliary pattern is formed at a plurality of locations.

Therefore, according to the invention described in the means 3, by forming a plurality of linear auxiliary patterns in the adjacent parts, it is possible to give an impression that the patterns are more consistent between the adjacent parts.

The invention described in means 4 is characterized in that, in the auxiliary pattern forming step, the linear auxiliary pattern having a narrower and smaller occupied area than the main pattern is formed at a plurality of locations. The gist of the method of manufacturing a decorative part is as follows.

Therefore, according to the invention described in the means 4, since the auxiliary pattern is narrower and has a smaller occupied area than the main pattern, the auxiliary pattern is formed between the adjacent parts while forming the auxiliary pattern to the extent that the entire pattern does not impair the impression of the main pattern. It is possible to give an impression that the pattern is consistent.

In the auxiliary pattern forming step, the auxiliary pattern is formed so that the auxiliary patterns are connected to each other at the edge of the component in the decorative parts used in a state of being arranged adjacent to each other. The gist of the method for producing a decorative part according to any one of means 2 to 4 is characterized in that it is formed.

These auxiliary patterns 27 are concave portions formed by removing a part of the ink layer 16 in the hydraulic transfer layer 15 by laser processing. The auxiliary pattern 27 has a depth that reaches the surface 14 of the component material 21. For this reason, the surface 14 of the component material 21 immediately below the auxiliary pattern 27 is exposed through the clear coat layer 18, and the color of the exposed portion is the original color of the component material 21 (gray, brown, ivory, etc.). Presents. That is, the color tone of the exposed portion of the surface 14 of the component material 21 is lighter (brighter) than the surrounding color tone, and the auxiliary pattern 27 has a higher contrast than the main pattern 24.

As shown in FIG. 9 and the like, the auxiliary pattern 27 in the

interior parts

11 and 12 of the present embodiment is linear and has an equal width, and is more than the dark-colored belt-shaped region 25 and the light-colored belt-shaped region 26 that constitute the main pattern 24. Is also formed narrow. In particular, in the present embodiment, about 2 to 6 auxiliary patterns 27 are arranged in parallel to form one auxiliary pattern group, and such auxiliary pattern groups are formed at a plurality of locations in the

interior parts

11 and 12, respectively. is doing. The area occupied by the auxiliary pattern 27 on the surface 14 of the component material 21 is considerably smaller than the area occupied by the main pattern 24, and is specifically set to about 1% to 20%.

As shown in FIG. 9 and the like, the two types of

interior parts

11 and 12 are arranged so that the component end edges 23 are aligned with each other (that is, the opening edge of the opening 13 of the interior part 11 and the outer edge of the interior part 12). Used in a state of being arranged adjacent to each other. The auxiliary pattern 27 according to the present embodiment extends from a part away from the part edge 23 toward the part edge 23, and its tip reaches the part edge 23. That is, the auxiliary handle 27 of this embodiment is formed at a location including at least the component edge 23. Further, the auxiliary pattern 27 on the interior part 11 side and the auxiliary pattern 27 on the interior part 12 side are connected to each other at the part edge 23 so as to be in a straight line when the

interior parts

11 and 12 are arranged adjacent to each other. , Pre-formed.

FIG. 1 shows a laser decorating device 30 used for decorating the surface 14 during the production of the

interior parts

11 and 12. This laser decoration device 30 is a device for drawing the auxiliary pattern 27 by irradiating the hydraulic transfer layer 15 formed on the component material 21 with the laser L1.

The laser decoration device 30 includes a laser irradiation device 31, a workpiece displacement robot 32, and a control device 33. The laser irradiation device 31 includes a laser generation unit 41 that generates a laser L1 (in this embodiment, a YAG laser having a wavelength of 1064 nm), a laser deflection unit 42 that deflects the laser L1, a laser generation unit 41, and a laser deflection unit 42. And a laser control unit 43 for controlling. The laser deflection unit 42 is an optical system in which a lens 44 and a reflection mirror 45 are combined. By changing the positions of the lens 44 and the reflection mirror 45, the irradiation position and focal length of the laser L1 are adjusted. It has become. The laser control unit 43 controls the irradiation time modulation, irradiation intensity modulation, irradiation area modulation, and the like of the laser L1.

The workpiece displacement robot 32 includes a robot arm 46 and a workpiece support 47 provided at the tip of the robot arm 46. The workpiece support 47 supports the component material 21 having the hydraulic transfer layer 15 formed on the surface thereof. The workpiece displacement robot 32 changes the irradiation position of the laser L1 on the component material 21 by driving the robot arm 46 and changing the position and angle of the component material 21.

The control device 33 is configured by a known computer including a CPU 50, a memory 51, an input / output port 52, and the like. The CPU 50 is electrically connected to the laser irradiation device 31 and the workpiece displacement robot 32, and controls them by various drive signals.

The memory 51 stores laser irradiation data for performing laser irradiation. Laser irradiation data is data obtained by converting CAD data. The CAD data is data obtained by converting the shape data of the surface of the component material 21, image data indicating the auxiliary pattern 27, and the like. The laser irradiation data stored in the memory 51 is data indicating the irradiation position, focal length, irradiation angle, irradiation area, irradiation time, irradiation intensity, irradiation cycle, irradiation pitch, and the like of the laser L1. When the

interior parts

11 and 21 are decorated, the CPU 50 reads the laser irradiation data from the memory 51, and drives and controls the laser irradiation device 31 based on the irradiation data.

Next, a method for decorating the surface 14 of these

interior parts

11 and 12 will be described.

First, a component material 21 molded into a predetermined shape is prepared (see FIG. 3), and a main pattern 24 is applied by affixing a hydraulic transfer layer 15 on the surface 14 by a conventionally known hydraulic transfer method (see FIG. 3). See 4; hydraulic transfer step). Specifically, after the activator is applied to a transfer film obtained by printing the printing layer 16 on a water-soluble substrate, it is floated on the water surface of a hydraulic transfer tank, and the water-soluble substrate is absorbed to dissolve or swell. Let me. In this state, the surface 14 side of the component material 21 is pressed from above the transfer film, and the printing layer 16 is attached to the surface 14 by water pressure. As a result, as shown in FIG. 4, the hydraulic transfer layer 15 having the dark-colored belt-like region 25 and the light-colored belt-like region 26 is transferred, and the main pattern 24 having a wood grain tone is imparted. Thereafter, the component material 21 is taken out of the water and washed and dried.

In the subsequent auxiliary pattern forming step, first, the component material 21 to which the hydraulic transfer layer 15 has been transferred is set on the work support 47 (see FIG. 1) of the work displacement robot 32. And the laser L1 is irradiated to the hydraulic transfer layer 15 on the surface 14 of the component raw material 21 by driving the laser irradiation device 31 (see FIG. 5). By this laser irradiation, a part of the ink layer 16 in the hydraulic transfer layer 15 is removed to a depth reaching the surface 14 of the component material 21 to form an auxiliary pattern 27 (see FIG. 6). Specifically, the CPU 50 reads laser irradiation data for performing laser irradiation from the memory 51. Then, the CPU 50 generates a drive signal based on the laser irradiation data, and outputs the generated drive signal to the laser irradiation device 31. The laser irradiation device 31 irradiates the hydraulic transfer layer 15 with the laser L1 based on the drive signal output from the CPU 50. The laser control unit 43 of the laser irradiation device 31 irradiates the laser L1 from the laser generation unit 41 and controls the laser deflection unit 42 according to a predetermined image data pattern. By this control, the irradiation position and focal position of the laser L1 are determined.

In the subsequent clear coat layer forming step, the clear coat layer 18 is formed on the hydraulic transfer layer 15 on which the auxiliary pattern 27 is formed (see FIG. 7). Specifically, in the present embodiment, a clear clear coating layer 18 having a thickness of about 10 μm to 100 μm is formed by spraying a transparent clear paint using an atomizing coater (not shown) and drying and curing. As a result, the

interior parts

11 and 12 of the present embodiment are completed.

Therefore, according to the present embodiment, the following effects can be obtained.

(1) As described above, according to the manufacturing method of the present embodiment, after the main pattern 24 is applied on the surface 14 of the component material 21 by the hydraulic transfer process, the main pattern 24 has a pattern by the auxiliary pattern forming process. Different auxiliary patterns 27 are formed. Here, the auxiliary pattern 27 is formed by removing a part of the ink layer 16 to a depth reaching the surface 14 of the component material 21 by laser processing. Therefore, the contrast is higher than that of the wood grain main pattern 24 made of the ink layer 16, and can be made more conspicuous than the main pattern 24. Moreover, according to laser processing, the fine auxiliary pattern 27 excellent in shape can be relatively easily and accurately applied to a desired position. Therefore, it is possible to improve the appearance quality of these

interior parts

11 and 12 as compared with the conventional product. Furthermore, according to the present embodiment, which combines the provision of the main pattern 24 by the hydraulic transfer method and the auxiliary pattern formation by the laser irradiation, it is possible to relatively easily realize a novel design that cannot be expressed only by the hydraulic transfer method. it can.

(2) In the present embodiment, in the first interior part 11 and the second interior part 12 used in a state of being arranged adjacent to each other, the auxiliary pattern 27 is formed at a location including at least the part edge 23 of both. Yes. Further, the auxiliary pattern 27 on the first interior part 11 side and the auxiliary pattern 27 on the second interior part 12 side are formed in advance so that their tips are connected to each other, and have a corresponding relationship with each other. Therefore, even if the main handle 24 does not match between the adjacent

interior parts

11 and 12, it is possible to give a strong impression that the handle is matched as a whole (see FIGS. 8 and 9). Therefore, a sense of unity and unity of the design between the

interior parts

11 and 12 can be obtained sufficiently and relatively easily, and appearance quality can be reliably improved.

(3) In the present embodiment, since the linear auxiliary patterns 27 that are narrower and have a smaller occupied area than the main pattern 14 are formed at a plurality of locations, the impression of the main pattern 24 as a whole component is not impaired. While forming the auxiliary pattern 27, it is possible to sufficiently give an impression that the patterns are matched between the adjacent

interior parts

11 and 12.

In addition, you may change embodiment of this invention as follows.

-Although auxiliary pattern 27 in

interior parts

11 and 12 of the above-mentioned embodiment was straight, it may be other than this (non-linear thing). For example, in the case of

interior parts

11A and 12A according to another embodiment shown in FIG. 11, semicircular auxiliary patterns 27A are formed at a plurality of locations on each part edge 23. The auxiliary pattern 27A on the interior part 11A side and the auxiliary pattern 27A on the interior part 12A side have a corresponding positional relationship, and are connected to each other at the part edge 23 to form a circle. Therefore, even in this embodiment, it is possible to give an impression that the patterns are matched between the

interior parts

11A and 12A, and a sense of unity and unity of the design can be obtained sufficiently and relatively easily.

-Although auxiliary pattern 27 in

interior parts

11 and 12 of the above-mentioned embodiment was connected at a part edge 23, it is not limited to this. For example, in the case of

interior parts

11B and 12B of another embodiment shown in FIG. 12, auxiliary patterns 27B having an isosceles triangle shape are formed at a plurality of locations slightly spaced from the respective component edge 23. The auxiliary patterns 27B of the adjacent

interior parts

11B and 12B are in a positional relationship corresponding to each other, but are not connected at the part edge 23. Even in such an embodiment, it is possible to give an impression that the patterns are matched to some extent between the

interior parts

11B and 12B, and a sense of unity and unity of the design can be obtained sufficiently and relatively easily.

In the above embodiment, the auxiliary handle 27 is formed on the two types of

interior parts

11 and 12 that are used in a state of being adjacent to each other. However, as in another embodiment shown in FIG. The auxiliary pattern 27C may be formed on the interior part 12C. The auxiliary pattern 27 </ b> C in the interior part 12 </ b> C is a strip-shaped arabesque pattern located at a position spaced from the part edge 23, and is arranged in parallel along the part edge 23.

-In the manufacturing method of the said embodiment, although the component raw material 21 which consists of ABS resin was used, you may use the component raw material 21 which consists of an acrylic resin, a polypropylene resin, a vinyl chloride resin etc., for example. The component material 21 is not limited to resin, and may be made of metal, for example.

In the above-described embodiment, the main pattern 24 having a wood grain is formed. However, the present invention is not limited to this, and a main pattern such as a geometric pattern may be formed.

-In the said embodiment, although the manufacturing method of the decorative component of this invention was materialized in the manufacturing method of the component of the console box which is a kind of interior component for motor vehicles, other interior components, for example, an armrest of a door, You may embody in the manufacturing method of components, such as an instrument panel, a center cluster, a cup holder, a glove box, an upper box, and an assist grip.
