Description

  The present invention relates to a surface decoration system for a decorative part for automobiles that is decorated by adding a pattern imitating a basic pattern on the curved surface of a resin automotive part material having a three-dimensional shape.

  For automobile interior parts, there are decorative parts (for example, console boxes, instrument panels, armrests, etc.) that add decoration to the surface of resin moldings (automobile parts materials) to improve design and quality. Many have been put to practical use. As a decoration method for adding decoration to such a decorative part for automobiles, hydraulic transfer is generally used (for example, see Patent Document 1).

The hydraulic transfer is a technique in which a special 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.
JP 54-33115 A

  However, when the above-described hydraulic transfer is performed, the pattern is stretched or distorted when the pattern is transferred to the resin molding. As a result, the pattern cannot be accurately added, resulting in variations in the pattern. In this case, the product yield deteriorates and the manufacturing cost increases. In addition, in order to realize a realistic wood grain pattern (for example, a concave part such as a conduit), a technique of hydraulically transferring a plurality of patterns is being studied. Therefore, it is difficult to position each picture accurately and it is difficult to put it into practical use. Furthermore, in order to realize a three-dimensional wood grain pattern, a method of providing unevenness on the surface of the resin molded body and performing hydraulic transfer on the surface has been studied. However, the wood grain pattern deviates from the uneven position, and these positions cannot be matched exactly. In this case, the wood grain pattern does not look three-dimensional and a sense of incongruity occurs, resulting in a defective product.

  In addition, in the case of hydraulic transfer, the transfer film after use becomes a waste material, so that the disposal cost is increased, and in addition, processing costs such as film removal treatment and drainage treatment are required. Furthermore, in the conventional hydraulic transfer, since the base pattern is formed by gravure printing, changing the base pattern requires a change in the design of the plate making, which is troublesome. Therefore, it is desired to develop a new technique for decorating by adding a pattern on a curved surface of a part material for automobiles by a method different from hydraulic transfer.

Then, the plurality of colored layers 11 to 14 formed on the upper surface 3 of the resin molded body 2 are selectively peeled off at different depths to partially expose the colored layers 11 to 14, thereby forming the base of the wood grain pattern. A pattern 16 imitating the pattern is drawn.

  Further, a transparent clear coat layer 17 for protecting the colored layers 11 to 14 is formed on the uppermost layer of the upper surface 3 of the resin molded body 2. The clear coat layer 17 of the present embodiment is formed so as to flatten the unevenness of the colored layers 11 to 14.

  In FIG. 3, the schematic block diagram of the surface decoration system 20 for manufacturing the decorative component 1 for motor vehicles of this Embodiment is shown.

  The surface decoration system 20 includes a coating device 21, a laser irradiation device 22, an inspection device 23, and a control device 24. In the surface decoration system 20, the control device 24 is electrically connected to the coating device 21, the laser irradiation device 22, and the inspection device 23, and outputs drive data to control the devices 21 to 23. , It has overall control over the entire system.

  The painting device 21 includes a robot arm 26 and a painting machine 27 attached to the tip of the robot arm 26. Based on the drive data output from the control device 24, the painting device 21 drives the robot arm 26 to spray the paint. And change the position. In addition, the coating apparatus 21 includes a cartridge exchange device (not shown) so that the paint cartridge 28 to be mounted on the painting machine 27 can be exchanged corresponding to each of the colored layers 11 to 14 based on the drive data output from the control device 24. It is configured. Then, the coating device 21 sprays the paint P of each color while replacing the paint cartridge 28 of the coating machine 27 to apply and coat the colored layers 11 to 14 on the upper surface 3 of the resin molded body 2. .

  The laser irradiation device 22 includes a laser generation unit 31 that generates the laser L, a laser deflection unit 32 that deflects the laser L, and a laser control unit 33 that controls the laser generation unit 31 and the laser deflection unit 32. The laser deflection unit 32 is an optical system in which a lens 35 and a reflection mirror 36 are combined, and the position of the lens 35 and the reflection mirror 36 is changed to adjust the irradiation position and focal position of the laser L. The laser control unit 33 controls, for example, irradiation time modulation, irradiation intensity modulation, irradiation area modulation, and the like of the laser L based on the drive data output from the control device 24.

  The inspection device 23 includes a CCD camera 38, and the CCD camera 38 shoots the wood grain pattern 16 drawn on the upper surface 3 of the resin molded body 2 to obtain image data (inspection image data) of the pattern 16. To the control device 24.

  The control device 24 is configured by a known computer including a CPU 40, a memory 41, an input / output port 42, and the like. The CPU 40 executes a control program using the memory 41 and performs drive control of the coating apparatus 21, the laser irradiation apparatus 22, and the inspection apparatus 23. The control device 24 has a function of performing color separation processing of the pattern 16. Then, the control device 24 performs a color separation process to separate the base pattern of the wood grain pattern into a plurality of different colors, generates a plurality of single color base pattern data, and stores them in the memory 41 (single color base pattern data storage unit). ing. In the present embodiment, the basic pattern of the wood grain pattern is decomposed into four color elements of dark brown, brown, light brown, and cream, and the monochrome basic pattern data of each color element is stored in the memory 41 in advance. . Further, the memory 41 includes coating conditions (coating time, coating amount of paint, thickness of the colored layers 11 to 14), and laser irradiation conditions (laser irradiation time, Data on conditions such as laser irradiation intensity and laser spot diameter are set in advance.

  Next, the operation example of the surface decoration system 20 of this Embodiment is demonstrated according to the flowchart of FIG. The process of FIG. 4 is started when the operator operates a process start button (not shown) provided in the control device 24 after setting the resin molded body 2 on the fixed table 51 (see FIG. 3). . 4 is executed by the CPU 40 of the control device 24.

  First, the CPU 40 serving as the laminating coating means driving data generating unit reads out the monochromatic basic pattern data from the memory 41, and based on the basic pattern data, driving data (driving coating means driving) for driving and controlling the coating apparatus 21. Data) is generated and the drive data is output to the painting apparatus 21 (step 100). The coating apparatus 21 is driven and controlled based on the driving data, and the coating layers 27 apply the colored layers 11 to 14. Specifically, the dark brown colored layer 11 is formed on the upper surface 3 (curved surface) of the resin molded body 2 by applying the coating material P1 using the coating machine 27 (see FIG. 5). Thereafter, the paint cartridge 28 of the coating machine 27 is replaced, and the paint to be sprayed is changed from the dark brown paint P1 to the brown paint P2, and the paint P2 is applied to apply a brown color on the dark brown colored layer 11. A colored layer 12 is laminated (see FIG. 6). Similarly, the paint sprayed from the coating machine 27 is changed from the brown paint P2 to the light brown paint P3, and the paint P3 is applied to form the light brown colored layer 13 on the brown colored layer 12 in a laminated manner. (See FIG. 7). Furthermore, the paint sprayed from the coating machine 27 is changed from the light brown paint P3 to the cream paint P4, and the cream colored layer 14 is laminated on the light brown colored layer 13 by applying the paint P4. Form (see FIG. 8). Here, each of the colored layers 11 to 14 formed in a laminated manner is a solid pattern layer (solid layer) having no pattern, and is laminated without being aligned.

  Thereafter, the CPU 40 as the laser irradiation means drive data generation unit generates drive data (laser irradiation means drive data) for driving and controlling the laser irradiation device 22 based on the monochrome basic pattern data read from the memory 41. The drive data is output to the laser irradiation device 22 (step 110).

  The laser irradiation device 22 is driven and controlled based on the drive data, and irradiates the colored layers 11 to 14 formed on the upper surface 3 of the resin molded body 2 with the laser L (see FIG. 9). At this time, in the laser irradiation device 22, the laser control unit 33 outputs the laser L from the laser generation unit 31, and controls the laser deflection unit 32 according to the pattern of the base pattern. By this control, the irradiation position and focal position of the laser L are changed, and the colored layers 11 to 14 are selectively peeled at different depths to partially expose the colored layers 11 to 14 (see FIG. 10). Specifically, in the wood grain pattern of the base pattern, the colored layers 12 to 14 are isolated to expose the surface of the colored layer 11 in the portion corresponding to the darkest portion, and the colored layer is exposed in the portion corresponding to the dark portion. 13 and 14 are peeled to expose the surface of the colored layer 12. Further, at a location corresponding to a slightly brighter part, the colored layer 14 is peeled off to expose the surface of the colored layer 13, and at a location corresponding to the brightest part, the colored layers 11 to 14 are left as they are. To expose. A wood grain pattern 16 is drawn on the upper surface 3 of the resin molded body 2 by the exposed portions of the colored layers 11 to 14.

  The CPU 40 of the control device 24 outputs drive data to the inspection device 23 and operates the CCD camera 38 to photograph the wood grain pattern 16 (actual pattern) drawn on the upper surface 3 of the resin molded body 2. Then, the obtained image data is taken from the inspection device 23 (step 120). Here, the CPU 40 generates a plurality of single-color actual picture data by performing color separation processing of the actual picture based on the image data fetched from the inspection apparatus 23. Thereafter, the CPU 40 as the pattern formation state pass / fail determination unit compares the generated single color actual pattern data with the plurality of single color basic pattern data stored in the memory 41 and draws it on the upper surface 3 of the resin molded body 2. The quality of the formed pattern 16 is determined (step 130).

  At this time, the CPU 40 displays the result of the pass / fail determination on a monitor (not shown). If it is determined that the formation state is defective, the CPU 40 changes the setting of the color elements, coating conditions, and the like of the colored layers 11 to 14 stored in the memory 41 and ends the present process (step 140). ). On the other hand, if it is determined that the formation state is good, the CPU 40 ends the present process without changing the settings of the color elements and coating conditions stored in the memory 41.

  Here, after a new resin molded body 2 on which the pattern 16 is not drawn is set on the fixed table 51, the processing of FIG. 4 is resumed when a processing start button (not shown) is operated. If settings such as color elements and coating conditions have been changed in the previous process, the processes in steps 100 to 140 are performed with the changed settings.

  In addition, when the operator checks the monitor of the control device 24 and determines that the formation state of the pattern 16 is good, the worker carries the resin molded body 2 on which the pattern 16 is drawn into the clear coat painting line of the next process. To do. On the other hand, when the worker determines that the formation state of the pattern 16 is defective, the worker collects the resin molded body 2 as a defective product. In addition, about the collect | recovered resin molding 2, you may carry in to the coating line of a clear coat, after correcting the pattern 16 by another process here.

  In the clear coat coating line, a clear paint layer 17 for protecting the colored layers 11 to 14 is formed by applying a clear paint to the upper surface 3 of the resin molded body 2 on which the wood grain pattern 16 is drawn. Is done. Through the above steps, the automotive decorative component 1 of the present embodiment is manufactured.

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

  (1) In the surface decoration system 20 of this Embodiment, since the several colored layers 11-14 laminated | stacked and formed by the coating device 21 are solid layers without a pattern, it does not need to align and each colored layer 11 to 14 can be easily formed. Moreover, since the colored layers 11 to 14 are selectively peeled off at different depths by laser irradiation and the colored layers 11 to 14 are partially exposed, irregularities corresponding to the grain of the pattern 16 can be formed. A three-dimensional pattern 16 similar to a real natural tree can be drawn. Further, since laser irradiation processing can accurately process a fine area, a clear pattern 16 with high resolution can be drawn. Furthermore, since the coating device 21 and the laser irradiation device 22 are controlled based on the monochrome base pattern data generated by the color separation processing, the uniform pattern 16 can be accurately obtained for the plurality of decorative parts 1 for automobiles. Can be drawn to. Further, in the conventional hydraulic transfer, since the base pattern is formed by gravure printing, the design change of the plate making is required when changing the base pattern, which is troublesome. On the other hand, in the case of changing the design of the base pattern in the present embodiment, it is sufficient to change the monochrome base pattern data stored in the memory 41, and the cost for the design change can be reduced compared to the case of the conventional hydraulic transfer. Can be suppressed.

  (2) In the surface decoration system 20 of the present embodiment, the inspection device 23 is provided, and the actually drawn pattern 16 is photographed by the CCD camera 38 of the inspection device 23 to obtain inspection image data. Then, the CPU 40 of the control device 24 generates a plurality of single-color actual picture data based on the inspection image data, and compares the plurality of single-color actual picture data with the plurality of single-color basic picture data stored in the memory 41. The If it does in this way, the quality of the formation state of the pattern 16 drawn by laser irradiation can be determined for every colored layer 11-14. Moreover, based on the quality result of the formation state of the pattern 16, the color element or the coating condition is adjusted, and the color of the colored layers 11-14, the thickness of the colored layers 11-14, and the like can be changed. It is possible to draw a more accurate pattern 16 that is close to.

  (3) In the automotive decorative component 1 according to the present embodiment, since the coloring layers 11 to 14 are darker toward the lower layer side, the concave portions deeply processed by laser irradiation processing are darker in color. It is expressed by Therefore, it is possible to reliably represent the pattern 16 having a three-dimensional effect close to natural wood having unevenness and shadows.

  (4) In the case of performing the conventional hydraulic transfer, it is necessary to float the transfer film on the water surface of the hydraulic transfer tank, which increases the size of the transfer device. On the other hand, in the surface decoration system 20 of the present invention, it is not necessary to use a relatively large apparatus, and space saving can be achieved.

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

  In the automotive decorative part 1 of the above embodiment, the pattern 16 is expressed by the four colored layers 11 to 14 of dark brown, brown, light brown, and cream, but the colored layers 11 to 14 The color elements and the number of layers can be appropriately changed according to the basic pattern. In addition to the wood grain pattern, examples of the base pattern include a textile fabric pattern and a plant fiber pattern.

It is not something. When the formation state of the pattern 16 is poor, the setting of the laser irradiation condition of the laser irradiation device 22 may be changed, or the setting of both the coating condition and the laser irradiation condition may be changed. In this way, the depth and width of the colored layers 11 to 14 to be peeled off by laser irradiation can be adjusted based on the quality determination result of the pattern formation state, and a more accurate pattern 16 closer to the base pattern. Can be drawn.

  In the surface decoration system 20 of the above-described embodiment, the monochromatic basic pattern data of the basic pattern is stored in the memory 41 in advance. For example, as the initial operation of the system, the CCD 38 of the inspection apparatus 23 performs basic processing. You may comprise so that the memory 41 may memorize | store the several monochrome base pattern data produced | generated based on the image data which image | photographed the pattern and obtained. Of course, a photographing unit different from the inspection device 23 may be provided, and a plurality of single-color basic pattern data may be generated based on image data acquired using the photographing unit.

  -In the surface decoration system 20 of the said embodiment, although the laser irradiation apparatus 22 performed laser irradiation only in one place, for example, a plurality of laser deflection parts 32 are provided, and processing by laser irradiation is performed in a plurality of places. You may comprise so that it can carry out simultaneously. If it does in this way, the process by laser irradiation can be performed rapidly and the decorative component 1 for motor vehicles can be manufactured in a short time.

  -In the surface decoration system 20 of the said embodiment, by controlling the laser deflection | deviation part 32, the irradiation position and focus position of the laser L are changed, and each coloring layer 11-14 is peeled by laser irradiation. However, the present invention is not limited to this. For example, a fixed table 51 (see FIG. 3) that fixes the resin molding 2 is configured to be three-dimensionally movable, and by moving the fixed table 51 side, the colored layers 11 to 14 are irradiated by laser irradiation. You may comprise so that peeling may be performed. Of course, the movement of the fixed table 51 and the change of the irradiation position or focal position of the laser L may be combined to separate the colored layers 11 to 14 by laser irradiation. If it does in this way, it will become possible to process the pattern 16 by laser irradiation rapidly.

For example, a plurality of coating machines 27 may be provided from the upstream side to the downstream side in the coating line, and the colored layers 11 to 14 may be formed in order by the respective coating machines 27.

  -In the surface decoration system 20 of the said embodiment, after forming the several colored layers 11-14, although the pattern 16 was drawn by processing each colored layer 11-14 collectively, it is limited to this. Is not to be done. For example, the pattern 16 may be drawn by performing laser irradiation processing each time the colored layers 11 to 14 are formed.
