Has been. As a decoration method for adding decoration to such a decorative part, hydraulic transfer is generally used (see, for example, Patent Document 1). Water pressure transfer is a technique in which a transfer film is floated on the surface of the water, and a predetermined pattern (pattern such as a wood grain pattern or a geometric pattern) printed on the film is transferred to the surface of the resin molded body by water pressure. According to this technique, printing on a three-dimensional curved surface can be performed.

  Further, as another decoration method, after forming a drawing layer composed of a plurality of colored layers on the surface of the resin molded body, the colored layer is selectively removed by laser irradiation and colored in different colors. A technique is considered in which a pattern is formed to add decoration by exposing a layer. In such a case, it is considered that the elongation and distortion of the pattern that has occurred during the hydraulic transfer can be prevented, and that a complicated pattern can be accurately drawn.

Data indicating the irradiation time, the irradiation intensity of the laser L, the spot diameter of the laser L, etc.) are stored in advance.

  Next, the manufacturing method of the decorative component 1 for automobiles will be described.

  First, a resin molded body 2 molded into a predetermined three-dimensional shape using a resin material (for example, ABS resin) is prepared. The resin molded body 2 is set on a fixed table 51 (see FIG. 3) by an operator.

  Next, a drawing layer forming step is performed to form the drawing layer 10 on the workpiece surface 3 a of the resin molded body 2. Specifically, the drawing layer forming process is executed in the order of transfer film preparation process → activation process → transfer process → removal process → drying process.

  First, in the transfer film preparation step, a transfer film is prepared by gravure printing a drawing layer 10 (a wood grain pattern layer in this embodiment) on a base material (not shown) made of a water-soluble or water-swellable film. At this point, the drawing layer 10 of the transfer film is dry and in a dry ink state. In addition, as a formation method of the drawing layer 10 with respect to a transfer film, well-known printing methods, such as screen printing, can be used besides gravure printing.

  In the subsequent activation step, an activator (not shown) is applied on the drawing layer 10 of the transfer film so that the drawing layer 10 is in the same state (adhesive state) as immediately after printing. Activated (fluidized) by dissolving or swelling. As a result, the drawing layer 10 is easily attached to the resin molded body 2 and is given an adhesive force. As a method for applying the activator, known methods such as spray coating, roll coating, gravure coating, curtain coating and the like are used.

  The activator of the present embodiment includes an organic solvent that can dissolve or swell the drawing layer 10 formed on the transfer film, viscosity adjustment for efficiently performing the transfer process, and the drawing layer 10 after transfer. And a binder resin capable of satisfactorily adhering to the workpiece surface 3a of the resin molded body 2. Further, the activator includes a plasticizer for preventing the drawing layer 10 fluidized by the application of the activator from spreading on the surface of the water, and prevents the coating layer cracking of the drawing layer 10 that occurs in the drying process after transfer. For example, a moisture-resistant pigment is blended as necessary.

  In the subsequent transfer step, the transfer film is floated on the surface of the treated water with the drawing layer 10 facing upward (that is, the base material facing downward). Then, with the transfer film floating on the water surface, the resin molded body 2 is pressed from above the transfer film, and the drawing layer 10 is transferred onto the workpiece surface 3a of the resin molded body 2 by water pressure.

  In the subsequent removing step, the work surface 3a of the resin molded body 2 is shower-washed to remove the unnecessary base material. The water temperature for this shower washing is about 25 ° C. to 50 ° C., and an appropriate temperature is set according to the material of the base material. The cleaning time is about 5 to 10 minutes. In the drying step, the drawing layer 10 is formed on the work surface 3 a of the resin molded body 2 by drying the moisture and the solvent attached to the resin molded body 2.

  After the drawing layer forming step, a clear coat layer forming step is performed to form a clear coat layer 17 that protects the drawing layer 10 against the workpiece surface 3a of the resin molded body 2. More specifically, the CPU 40 generates a drive signal and outputs the generated drive signal to the coating apparatus 21. Then, the painting device 21 starts painting the clear coat layer 17 by the painting machine 27 based on the drive signal output from the CPU 40. Specifically, the clear coat layer 17 is formed on the workpiece surface 3 a of the resin molded body 2 by applying the clear paint P using the coating machine 27.

  In the subsequent imaging process, the CPU 40 generates a drive signal and outputs the generated drive signal to the CCD camera 25. The CCD camera 25 captures an image of the actual picture 16 drawn on the drawing layer 10 based on the drive signal output from the CPU 40. Further, the CCD camera 25 generates pattern image data indicating the pattern 16 based on the captured image of the actual pattern 16. Note that the pattern image data has a drawing area, and a plurality of drawing dots are formed in a dotted pattern (in the present embodiment, in a lattice shape). Thereafter, the CCD camera 25 outputs the obtained pattern image data to the CPU 40 as an imaging signal.

  In the subsequent data conversion step, the CPU 40 converts the pattern image data indicated by the imaging signal output from the CCD camera 25 into laser irradiation data for performing laser irradiation. Next, in the data storage step, the CPU 40 stores the converted laser irradiation data in the memory 41. Further, in the parameter setting step, the CPU 40 sets laser irradiation parameters (laser L irradiation position, focal position, irradiation angle, irradiation area, irradiation time, irradiation intensity, etc.) used for laser irradiation.

  Thereafter, a laser irradiation process is performed, and the CPU 40 performs laser irradiation on the clear coat layer 17 based on the laser irradiation data stored in the memory 41, whereby the groove 15 for decorating the pattern 16 is used as a reference. Formed at a predetermined position. Specifically, the CPU 40 reads the laser irradiation data stored in the memory 41, generates a drive signal based on the read laser irradiation data, and outputs the generated drive signal to the laser irradiation device 22. The laser irradiation device 22 irradiates the clear coat layer 17 formed on the work surface 3a of the resin molded body 2 with the laser L (see FIG. 3) based on the drive signal output from the CPU 40. The laser control unit 33 of the laser irradiation device 22 irradiates the laser L from the laser generation unit 31 and controls the laser deflection unit 32 according to the pattern of the pattern 16. By this control, the clear coat layer 17 is sublimated or embrittled by changing the irradiation position or the focal position of the laser L, so that only the clear coat layer 17 is applied according to the pattern of the pattern 16 without removing the drawing layer 10. Is selectively removed. As a result, the clear coat layer 17 is peeled off, and the groove 15 is formed at a predetermined position with reference to the pattern 16.

  In the laser irradiation process, the CPU 40 reads the laser irradiation data stored in the memory 41, generates a drive signal based on the read laser irradiation data, and outputs the generated drive signal to the workpiece displacement robot 23. Based on the drive signal output from the CPU 40, the workpiece displacement robot 23 drives the robot arm 29 to change the position and angle of the workpiece (resin molded body 2) supported by the workpiece support unit 30, thereby clear coating. The irradiation position and irradiation angle of the laser L with respect to the layer 17 are changed. The automotive decorative part 1 is manufactured through the above steps.

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

  (1) In the manufacturing method of the automotive decorative part 1 according to the present embodiment, by performing laser irradiation on the clear coat layer 17 based on the laser irradiation data obtained by converting the pattern image data indicating the pattern 16. The groove 15 is formed at a predetermined position in the clear coat layer 17 with the pattern 16 as a reference. As a result, the design of the pattern 16 and the groove portion 15 is the same, and when the pattern 16 is visually recognized through the clear coat layer 17, the appearance of the pattern 16 in the portion where the groove portion 15 is present and the portion where the groove portion 15 is not present. To be different. Thereby, since the pattern 16 with a three-dimensional effect can be provided to the decorative component 1 for automobiles, the appearance quality of the decorative component 1 for automobiles can be improved.

  Further, for example, there is no need to use a method of performing hydraulic transfer on the workpiece surface 3a of the resin molded body 2 having irregularities or a method of transferring a transfer film having irregularities to the workpiece surface 3a of the resin molded body 2. However, since the pattern 16 with a three-dimensional effect can be provided to the decorative part 1 for automobiles, the manufacturing cost of the decorative part 1 for automobiles can be suppressed.

  (2) In this embodiment, since the direction of light passing through the groove 15 is changed by forming the plurality of grooves 15 in the clear coat layer 17 in the laser irradiation step, the light is visible through the clear coat layer 17. The brightness and color tone of the drawing layer 10 change. That is, the clear coat layer 17 has a function as a spectroscope that refracts, diffracts, and interferes with light. That is, in addition to forming the drawing layer 10 with the three colored layers 11 to 13 and forming the plurality of groove portions 15 in the clear coat layer 17, the light and darkness and color tone of the drawing layer 10 appear to change. Can be expected.

  (3) In the automotive decorative component 1 of the present embodiment, the drawing layer 10 is completely protected by the clear coat layer 17, and the drawing layer 10 is exposed even if the groove portion 15 is formed in the clear coat layer 17. Therefore, the appearance quality of the automotive decorative part 1 can be maintained over a long period of time.

[Second Embodiment]
Next, a second embodiment of the present invention will be described with reference to the drawings. Here, the description will focus on the parts that are different from the first embodiment, and the common parts will not be described in place of the same member numbers.

  The present embodiment is different from the first embodiment in that laser irradiation on the clear coat layer 17 is used for correcting a defective portion. Specifically, the imaging process is executed after the drawing layer forming process and before the clear coat layer forming process. In the imaging process, the CCD camera 25 outputs the pattern image data indicating the actual pattern 16 drawn on the drawing layer 10 to the CPU 40 as an imaging signal.

  Then, after the imaging process, a defective portion detection process is executed. In the defective portion detection step, the CPU 40 is based on the pattern image data indicated by the imaging signal output from the CCD camera 25, and the defective portion 61 (see FIGS. 4A and 4B) and the surplus portion 62 of the drawing layer 10. At least one defective part is detected among the foreign matter adhesion part 63 (see FIG. 5A) (see FIG. 5A). Specifically, the CPU 40 determines whether or not the pattern image data matches the basic pattern data indicating the basic pattern stored in the memory 41. Then, the CPU 40 determines that there is a defective portion when the pattern image data and the basic pattern data do not match, and determines what the existing defective portion is. Here, the defective portion 61 refers to a portion in which the colored layer 13 is missing although the colored layer 13 should originally exist. The surplus portion 62 is a portion where wrinkles are formed in the colored layer 13 during hydraulic transfer. Further, the foreign matter adhering portion 63 refers to a portion where dust adheres on the drawing layer 10 (the colored layer 12 in the present embodiment). In addition, when a defective part is detected in a defective part detection process, CPU40 performs the data conversion process which converts pattern image data into laser irradiation data.

  When it is determined that the defective part is the defective part 61, the CPU 40 performs a laser irradiation process after the clear coat layer forming process. More specifically, the CPU 40 irradiates the clear coat layer 17 with laser based on the laser irradiation data, thereby forming the groove portion 15a immediately above the defect portion 61 in the clear coat layer 17 and existing in the defect portion 61. Supplement the power coloring layer 13 (see FIG. 4B). That is, since the groove portion 15a is a shadowed portion, when the drawing layer 10 is visually recognized through the clear coat layer 17, it is as if the colored layer 13 is present in the defective portion 61 located immediately below the groove portion 15a. Visual effect that looks like

  On the other hand, when it is determined that the defective portion is the surplus portion 62 or the foreign matter adhesion portion 63, the CPU 40 performs a laser irradiation step before the clear coat layer forming step. Specifically, the CPU 40 removes the surplus portion 62 and the foreign matter adhesion portion 63 by performing laser irradiation on the drawing layer 10 based on the laser irradiation data (see the broken line portion in FIG. 5B).

  Moreover, in this embodiment, an imaging process, a defective part detection process, a data conversion process, and a laser irradiation process are performed again after a clear coat layer formation process. In the defective portion detection step, the CPU 40 is based on the picture image data indicated by the imaging signal output from the CCD camera 25, and the foreign matter adhesion portion 64 of the clear coat layer 17 (see FIGS. 6A and 7A). Is detected as a defective part. Specifically, the CPU 40 determines whether or not the pattern image data and the basic pattern data stored in the memory 41 match. If the pattern image data and the basic pattern data do not match, the CPU 40 is defective. It is determined that the part exists. Here, the foreign matter adhering portion 64 refers to a portion where dust adheres on the clear coat layer 17 or in the clear coat layer 17.

  And when it determines with a defective part existing, CPU40 performs a laser irradiation process. More specifically, when the foreign matter adhering portion 64 is a portion where dust adheres on the clear coat layer 17, the CPU 40 performs laser irradiation on the clear coat layer 17 based on the laser irradiation data, thereby obtaining the foreign matter.
