The modeling apparatus 10 of the first embodiment is shown in FIG. The modeling apparatus 10 includes a transport device 20 , a modeling unit 22 , an imaging unit 24 and a control device (see FIG. 2) 26 . The conveying device 20 , the modeling unit 22 and the imaging unit 24 are arranged on a base 28 of the modeling device 10 . The base 28 has a generally rectangular shape, and in the following description, the longitudinal direction of the base 28 is the X-axis direction, the short side direction of the base 28 is the Y-axis direction, and both the X-axis direction and the Y-axis direction are perpendicular to each other. The direction will be referred to as the Z-axis direction for explanation.

The transport device 20 includes an X-axis slide mechanism 30 and a Y-axis slide mechanism 32 . The X-axis slide mechanism 30 has an X-axis slide rail 34 and an X-axis slider 36 . The X-axis slide rail 34 is arranged on the base 28 so as to extend in the X-axis direction. The X-axis slider 36 is held by an X-axis slide rail 34 so as to be slidable in the X-axis direction. Further, the X-axis slide mechanism 30 has an electromagnetic motor (see FIG. 2) 38, and by driving the electromagnetic motor 38, the X-axis slider 36 moves to any position in the X-axis direction. Also, the Y-axis slide mechanism 32 has a Y-axis slide rail 50 and a stage 52 . The Y-axis slide rail 50 is arranged on the base 28 so as to extend in the Y-axis direction and is movable in the X-axis direction. One end of the Y-axis slide rail 50 is connected to the X-axis slider 36 . A stage 52 is held on the Y-axis slide rail 50 so as to be slidable in the Y-axis direction. Furthermore, the Y-axis slide mechanism 32 has an electromagnetic motor (see FIG. 2) 56, and by driving the electromagnetic motor 56, the stage 52 moves to any position in the Y-axis direction. As a result, the stage 52 is moved to an arbitrary position on the base 28 by driving the X-axis slide mechanism 30 and the Y-axis slide mechanism 32 .

The stage 52 has a base 60, a holding device 62, and an elevating device (see FIG. 2) 64. The base 60 is formed in a flat plate shape, and a pallet (see FIG. 4) 70 is placed on the upper surface thereof. The holding devices 62 are provided on both sides of the base 60 in the X-axis direction. Both edges in the X-axis direction of the substrate placed on the base 60 are sandwiched by the holding device 62, so that the pallet 70 is fixedly held. The lifting device 64 is arranged below the base 60 and lifts the base 60 up and down.

The modeling unit 22 is a unit that models a resin layer on the pallet 70 placed on the base 60 of the stage 52 , and has a printing section 72 and a curing section 74 . The printing unit 72 has an inkjet head (see FIG. 2) 76 and ejects ultraviolet curable resin onto the pallet 70 placed on the base 60 . The inkjet head 76 may be, for example, a piezo system using piezoelectric elements, or a thermal system in which resin is heated to generate bubbles and ejected from nozzles.

The curing section 74 has a flattening device (see FIG. 2) 78 and an irradiation device (see FIG. 2) 80. The flattening device 78 flattens the upper surface of the ultraviolet curable resin ejected onto the pallet 70 by the inkjet head 76. For example, the surface of the ultraviolet curable resin is smoothed and the surplus resin is removed by a roller or the like. By scraping off with a blade, the thickness of the UV curable resin is made uniform. Further, the irradiation device 80 has a mercury lamp or an LED as a light source, and irradiates the ultraviolet curing resin discharged onto the pallet 70 with ultraviolet rays. As a result, the ultraviolet curable resin discharged onto the pallet 70 is cured.

The control device 26 also includes a controller 84, a plurality of drive circuits 86, an image processing device 87, and a storage device 88, as shown in FIG. A plurality of drive circuits 86 are connected to the

electromagnetic motors

38 , 56 , holding device 62 , lifting device 64 , inkjet head 76 , flattening device 78 and irradiation device 80 . The controller 84 includes a CPU, ROM, RAM, etc., is mainly a computer, and is connected to a plurality of drive circuits 86 . Accordingly, the controller 84 controls the operations of the transport device 20 and the modeling unit 22 . The controller 84 is also connected to the image processing device 87 . The image processing device 87 processes the imaging data obtained by the camera 82, and the controller 84 acquires various information from the imaging data. A storage device 88 stores various data for forming a modeled object, and is connected to the controller 84 . Thereby, the controller 84 controls the operations of the transport device 20 and the modeling unit 22 according to the data stored in the storage device 88 .

In the modeling apparatus 10, according to the data stored in the storage device 88, the ultraviolet curable resin is discharged onto the pallet 70 according to the data stored in the storage device 88, and is cured by irradiation with ultraviolet rays, thereby forming a shape corresponding to the data. things are shaped. Specifically, the pallet 70 is set on the base 60 of the stage 52 . A release film 100 is laid on the upper surface of the pallet 70 as shown in FIG. Then, when the pallet 70 is set on the base 60 of the stage 52 , the stage 52 is moved below the modeling unit 22 .

Then, in the modeling unit 22, the inkjet head 76 ejects the ultraviolet curable resin onto the pallet 70 according to the data stored in the storage device 88 to print. For example, as shown in FIG. 3, the storage device 88 stores print data for printing the characters "FUJI". Note that FIG. 3 is a diagrammatic representation of the printing data, and the actual printing data includes the coordinates for ejecting the ultraviolet curable resin for each pixel. Then, the inkjet head 76 ejects the ultraviolet curable resin onto the pallet 70 according to the data stored in the storage device 88, so that "FUJI" is printed on the release film 100 of the pallet 70 as shown in FIG. characters are printed. Note that the inkjet head 76 ejects the ultraviolet curable resin for each pixel when ejecting the ultraviolet curable resin onto the pallet 70 according to the data stored in the storage device 88 . Then, the controller 84 sequentially stores the coordinates of pixels for which ejection has been completed.

Subsequently, when the ultraviolet curable resin is discharged and the characters "FUJI" are printed on the pallet 70, the ultraviolet curable resin is flattened in the curing section 74 so that the film thickness of the ultraviolet curable resin becomes uniform. It is planarized by device 78 . Then, the irradiation device 80 irradiates the ultraviolet curing resin with ultraviolet rays. As a result, a modeled object with letters "FUJI" is formed on the pallet 70. FIG.

However, an error or the like occurs in the printing apparatus 10 while the letters "FUJI" are being printed. There is a risk that printing will not be performed properly when the work is resumed after setting the printer to . Specifically, in the printing section 72 of the modeling unit 22, an error or the like occurs while the inkjet head 76 is discharging the ultraviolet curable resin onto the pallet 70, and the operator must may be taken out of the modeling apparatus 10 . At this time, as shown in FIG. 5, the pallet 70 may have only the letter "F" printed thereon. That is, at the timing when the inkjet head 76 in the printing unit 72 completes printing the letter "F" and before printing the letter "U", an error or the like occurs, and the operator cannot print the letter "F". may be taken out of the modeling apparatus 10 . After the operator removes the pallet 70 from the modeling apparatus 10 and resolves the error, the operator resets the pallet 70 on the base 60 of the stage 52 to resume work.

At this time, the operator needs to reset the pallet 70 on the base 60 with a posture facing the same direction as the pallet set direction when it was taken out from the modeling apparatus 10 . That is, for example, when the pallet is set on the base 60 with the character "F" facing the correct direction as shown in FIG. , after removing the pallet, it is necessary to reset the pallet with the letter "F" facing in the correct direction. However, as shown in FIG. 5, even though the pallet was set on the base 60 with the character "F" facing the correct direction, the operator, after taking out the pallet, As shown, the pallet may be reset with the letter "F" upside down 180 degrees. Then, when the printing operation is resumed in the modeling apparatus 10 in such a state, as shown in FIG. The characters of "UJI" facing the direction are printed. During printing by the inkjet head 76, as described above, the ultraviolet curable resin is ejected for each pixel, and the controller 84 stores the coordinates of pixels for which ejection has been completed. Therefore, when the printing operation is restarted after the completion of the printing operation of the character "F" and the printing operation is stopped, the characters "UJI" are printed on the pallet. In addition, in FIG. 7, the upside-down "F" and the right-facing "I" are entirely overlapped, so the "I" cannot be visually recognized.

As described above, an error or the like occurs during printing of the ultraviolet curable resin, and after the operator takes out the pallet 70 from the modeling apparatus 10, the operator sets the pallet 70 on the stage 52 again and restarts the work. If so, it may not be possible to print properly. In view of this, in the modeling apparatus 10, the pallet set on the base 60 is imaged by the imaging unit 24, the set direction of the pallet is specified, and print data corresponding to the set direction of the pallet is obtained. is used to print the UV curable resin onto the pallet.

Specifically, as shown in FIG. 8, three reference marks 110 are marked on three of the four corners of the pallet 70, and no reference mark 110 is marked on the remaining one corner. A pallet posture in which one corner with no reference mark 110 is located at the lower right (hereinafter referred to as “first posture”: see FIG. 8) and a corner with no reference mark 110 The pallet 70 is set on the base 60 in one of the postures of the pallet located on the upper left (hereinafter referred to as "second posture"; see FIG. 9). That is, the pallet setting direction in which the pallet 70 is in the first posture (hereinafter referred to as the “first setting direction”; see FIG. 8) and the pallet setting direction in which the pallet 70 is in the second posture (hereinafter referred to as the “first setting direction”). The pallet 70 is set on the base 60 in either one of two setting directions (refer to FIG. 9).

When the pallet 70 is set on the base 60 of the stage 52, the stage 52 is moved below the imaging unit 24, and the camera 82 in the imaging unit 24 images the pallet 70 set on the base 60. do. Then, imaging data obtained by the imaging is analyzed by the controller 84, and based on the imaging data, it is determined whether the set direction of the pallet 70 on the base 60 is the first set direction or the second set direction.

Next, the stage 52 is moved below the modeling unit 22 . Then, in the printing unit 72 of the modeling unit 22, the inkjet head 76 discharges the ultraviolet curable resin onto the pallet 70 according to the printing data corresponding to the pallet setting direction calculated by the controller 84 to print. As described above, the storage device 88 stores the print data (see FIG. 3) for printing the characters "FUJI". is data for printing (hereinafter referred to as "first data for printing"). That is, the storage device 88 stores the first print data for printing the characters "FUJI" on the pallet 70 set on the base 60 in the first posture. On the other hand, print data corresponding to the second setting direction (hereinafter referred to as "second print data"), that is, print the characters "FUJI" on the pallet 70 set on the base 60 in the second orientation. The second print data for printing is not stored in the storage device 88 .

When the controller 84 determines that the set direction of the pallet 70 is the first set direction (see FIG. 8), the inkjet head 76 is stored in the storage device 88 in the printing section 72 of the modeling unit 22. The UV curable resin is discharged onto the pallet 70 in accordance with the first printing data stored in the pallet 70 for printing. At this time, when the ink jet head 76 completes printing the letter "F" and before printing the letter "U", an error or the like occurs, and the operator cannot print the letter "F" as shown in FIG. ” printed thereon may be taken out of the modeling apparatus 10 . After the operator removes the pallet 70 from the modeling apparatus 10 and resolves the error, the operator resets the pallet 70 on the base 60 of the stage 52 to resume work.

Subsequently, when the pallet 70 is reset on the base 60, the stage 52 is moved below the imaging unit 24, and the camera 82 in the imaging unit 24 images the pallet 70 set on the base 60. . Then, imaging data obtained by the imaging is analyzed by the controller 84, and based on the imaging data, it is determined whether the set direction of the pallet 70 on the base 60 is the first set direction or the second set direction. At this time, when it is determined that the set direction of the pallet 70 is the first set direction (see FIG. 10), the inkjet head 76 is stored in the storage device 88 in the printing section 72 of the modeling unit 22. According to the first printing data, the ultraviolet curable resin is printed on the palette 70 with the letters "UJI". As described above, since the controller 84 stores the coordinates of the discharged pixels, the characters "UJI" are printed on the pallet 70 on which the characters "F" are printed. As a result, the pallet 70 (see FIG. 10) on which the letters "F" are printed in the correct direction is printed with the letters "UJI" in the correct direction, and as shown in FIG. , and the characters "FUJI" are printed on the palette 70 appropriately.

On the other hand, after resetting the pallet 70 on the base 60, if it is determined that the setting direction of the reset pallet 70 is the second setting direction (see FIG. 12), the printing of the modeling unit 22 In part 72, the inkjet head 76 prints the UV curable resin on the palette 70 according to the second print data. However, as described above, although the storage device 88 stores the first printing data for printing the UV curable resin on the pallet in the first set direction, it is possible to print the UV curable resin on the pallet in the second set direction. The second print data for printing is not stored. Therefore, the controller 84 creates the second print data based on the first print data stored in the storage device 88 . That is, the controller 84 prints the characters "FUJI" turned upside down based on the first print data (see FIG. 3) for printing the characters "FUJI" in the correct direction. 2nd print data (see FIG. 13). The method for creating the second print data is a well-known technique and will not be described in detail. By rotating in the direction, the second print data can be created.

Then, when the second printing data is created by the controller 84, the inkjet head 76 prints the characters "UJI" on the palette 70 with the ultraviolet curable resin according to the second printing data. As a result, the pallet 70 (see FIG. 12) on which the upside-down character "F" is printed is printed with the upside-down character "UJI". , the characters "FUJI" are properly printed on the palette 70. As shown in FIG.

In this manner, the pallet setting direction is specified based on the image data of the pallet, and the printing operation is interrupted by printing the ultraviolet curable resin on the pallet using the printing data corresponding to the pallet setting direction. Appropriate printing work can be performed in the case of Moreover, even when the printing operation is not interrupted, the UV curable resin can be printed in a shape corresponding to the set direction of the pallet.

In addition, when the pallet setting direction is different from the predetermined direction, the operation of the modeling apparatus 10 is stopped and an error screen or the like is displayed, thereby prompting the operator to correct the pallet setting direction. . For example, since the first print data is stored in the storage device 88, when the set direction of the pallet is the first set direction, print processing is executed according to the first print data, and the set direction is the first set direction. In the case of the 2-set direction, it is also possible to stop the operation of the modeling apparatus 10 and display an error screen. However, if the operation of the modeling apparatus 10 is stopped in this way, the working time of the modeling apparatus becomes longer. On the other hand, by executing the printing process on the pallet using the print data according to the setting direction, the operation of the modeling apparatus can be continued without stopping the operation of the modeling apparatus. This makes it possible to shorten the working time.

It should be noted that the second printing data is erased after the printing of the ultraviolet curable resin onto the pallet according to the second printing data is completed. Further, if the characters "FUJI" are printed on the pallet 70 without interrupting the printing of the ultraviolet curable resin onto the pallet according to the first print data, the second print data is not created. That is, the second print data is created only when printing on the pallet in the second orientation is required, and when the second print data is created, printing according to the second print data is completed. After that, the second print data is erased. Thereby, an increase in the storage capacity of the storage device 88 can be suppressed.

Further, the controller 84 has a determination section 120, a data creation section 122, and a printing section 124, as shown in FIG. The determining unit 120 is a functional unit for determining whether the pallet setting direction is the first setting direction or the second setting direction based on the imaging data. The data creation unit 122 is a functional unit for creating the second print data based on the first print data. The printing unit 124 is a function for printing the ultraviolet curable resin using printing data according to the set direction of the pallet.

Information is sent and received.

In the work system 150, a circuit is formed on the pallet 70 with the configuration described above. Specifically, the pallet 70 is carried into the modeling work machine 152 by the pair of transport lanes 212 of the carry-in device 166 . As described above, the pallet 70 has three reference marks 110 on three of the four corners of the pallet 70, and no reference mark 110 on the remaining one corner. The pallet 70 can be transported by the pair of transport lanes 212 of the carry-in device 166 only in one of the first posture (see FIG. 8) and the second posture (see FIG. 9). Then, the pallet 70 is transferred onto the stage 182 from the pair of transport lanes 212 of the carry-in device 166 by the operation of the transfer device 170 . Therefore, the pallet 70 is set on the stage 182 in one of the first posture and the second posture. That is, the pallet 70 is set on the stage 182 in either the first setting direction (see FIG. 8) or the second setting direction (see FIG. 9). A release film 100 is laid on the pallet 70 .

Then, on the release film 100 of the pallet 70 set on the stage 182, the resin layer forming unit 162 forms a resin laminate 330 as shown in FIG. The resin layered body 330 is formed by repeating the ejection of the ultraviolet curable resin from the inkjet head 198 and the irradiation of the ultraviolet ray by the irradiation device 194 to the ejected ultraviolet curable resin.

Specifically, when the pallet 70 is placed on the stage 182 , the stage 182 moves below the resin ejection device 190 of the resin layer forming unit 162 . Then, in the resin ejection device 190 , the ink jet head 198 ejects the UV curable resin onto the upper surface of the pallet 70 in the form of a thin film. Subsequently, when the ultraviolet curable resin is discharged in the form of a thin film, the stage 182 moves below the flattening device 192, and the ultraviolet curable resin is spread to the flattening device 192 so that the film thickness of the ultraviolet curable resin becomes uniform. is flattened by Then, the stage 182 moves below the irradiation device 194, and the irradiation device 194 irradiates the thin film-like UV curable resin with UV rays. As a result, a thin resin layer 332 is formed on the release film 100 of the pallet 70 .

Next, the stage 182 moves below the resin ejection device 190 , and the inkjet head 198 ejects a thin film of ultraviolet curable resin onto the thin resin layer 332 . Subsequently, the stage 182 moves below the flattening device 192, and the flattening device 192 flattens the thin film of the ultraviolet curable resin. Then, the stage 182 moves below the irradiation device 194 , and the irradiation device 194 irradiates the ultraviolet curable resin discharged in the form of a thin film with ultraviolet rays, thereby forming a thin film on the resin layer 332 in the form of a thin film. A resin layer 332 is laminated. In this way, the resin layered body 330 is formed by repeating the discharge of the ultraviolet curable resin onto the thin resin layer 332 and the irradiation of the ultraviolet rays to laminate a plurality of resin layers 332 .

When the resin laminate 330 is formed by the above-described procedure, the stage 182 moves below the ink ejection device 202 of the wiring forming unit 164 . Then, in the ink ejection device 202, as shown in FIG. 19, the inkjet head 208 linearly ejects the metal ink 336 onto the upper surface of the resin laminate 330 according to the circuit pattern. Next, the stage 182 moves below the infrared irradiation device 204, and the infrared irradiation device 204 irradiates the metal ink 336 with infrared rays. This dries the metal ink 336 and forms the wiring 338 on the resin laminate 330 .

Subsequently, when the resin laminate 330 and wiring 338 are formed on the release film 100 of the pallet 70 , the stage 182 moves between the loading device 166 and the unloading device 168 . Subsequently, the pallet 70 is transferred from the stage 182 onto the pair of transport lanes 216 of the carry-out device 168 by the transfer device 170 . Then, the pallet 70 is carried out from the modeling work machine 152 by the operation of the carry-out device 168 and carried into the mounting work machine 154 .

In the mounting work machine 154, the pallet 70 carried in is transported to the work position by the pair of conveyor belts 272 of the transport device 260, and is fixedly held by the substrate holding device 276 at that position. Also, the tape feeder 306 feeds taped components and supplies electronic components (see FIG. 20) 340 at the supply position. Then, the mounting head 264 moves above the supply position of the electronic component 340 , and the suction nozzle 300 sucks and holds the electronic component 340 . Subsequently, the mounting head 264 moves above the pallet 70 and mounts the held electronic component 340 on the upper surface of the resin laminate 330 formed on the pallet 70, as shown in FIG. At this time, the electronic component 340 is mounted on the upper surface of the resin laminate 330 so that the electrodes 342 of the electronic component 340 are in contact with the wiring 338 . As a result, a circuit including the electronic component 340 connected to the wiring 338 on the upper surface of the resin laminate 330 is formed.

In the forming work machine 152 of the work system 150 forming the circuit in this way, as in the first embodiment, the pallet 70 set on the stage 182 is imaged by the camera 226, and based on the imaging data obtained by the imaging, , whether the set direction of the pallet 70 is the first set direction or the second set direction. Then, the printing of the ultraviolet curable resin and the printing of the metal ink are executed according to the printing data corresponding to the set direction of the pallet. Printing according to the print data according to the set direction of the pallet will be described below. However, it is difficult to understand the difference between the first printing data of the ultraviolet curable resin corresponding to the first set direction and the second printing data of the ultraviolet curable resin corresponding to the second setting direction when diagrammed. , the case where the metal ink is printed according to the printing data according to the set direction of the palette.

First, when the pallet 70 is set on the stage 182 , the stage 182 is imaged by the camera 226 . Then, imaging data obtained by the imaging is analyzed by the controller 250 of the control device 172, and based on the imaging data, it is determined whether the set direction of the pallet 70 is the first set direction or the second set direction.

Next, the stage 182 moves below the resin layer forming unit 162, and the resin laminate 330 is formed on the release film 100 of the pallet 70 according to the procedure described above. At this time, the UV curable resin is printed according to the printing data corresponding to the set direction of the pallet. Since it is the same as the method, the explanation is omitted. Then, when the resin laminate 330 is formed on the release film 100 of the pallet 70, the stage 182 moves below the wiring forming unit 164, and in the wiring forming unit 164, the inkjet head 208 moves in the set direction of the pallet. The metal ink is ejected onto the resin layered body 330 in accordance with the printing data corresponding to the above to print.

As the printing data for the metallic ink, the storage device 256 stores first printing data for printing the metallic ink on the pallet 70 set on the stage 182 in the first posture. FIG. 21 shows a diagrammatic representation of the first print data. On the other hand, the second printing data for printing the metallic ink on the pallet 70 set on the stage 182 in the second posture is not stored in the storage device 256 . That is, in the second embodiment as well, the storage device 256 does not store the second print data, and only the first print data is stored in the storage device 256, as in the first embodiment.

Then, when it is determined that the set direction of the pallet 70 is the first set direction (see FIG. 8) based on the imaging data, the inkjet head 208 is stored in the storage device 256 in the wiring forming unit 164. The metal ink is ejected according to the first printing data. Then, when the printing of the metal ink according to the first printing data is completed, the metal ink 336 is printed on the resin layered body 330 as shown in FIG. 22 . A description of the case where the printing of the metal ink is interrupted is omitted because it overlaps with the description of the first embodiment.

On the other hand, when it is determined that the set direction of the pallet 70 is the second set direction (see FIG. 9) based on the imaging data, the wiring forming unit 164 causes the inkjet head 208 to operate according to the second printing data. Eject metal ink. However, as described above, the storage device 256 stores the first printing data for printing the metallic ink on the palette in the first set direction, but the metallic ink is printed on the palette in the second set direction. The second print data for is not stored. Therefore, the controller 250 creates the second print data based on the first print data stored in the storage device 256 . At this time, for example, by rotating the position of the pixel indicating the ejection position of the metal ink in the first print data shown in FIG. 21 by 180 degrees, the second print data schematized as shown in FIG. created. Then, in the wiring forming unit 164, the inkjet head 208 ejects the metal ink according to the second printing data. At this time, when the printing of the metal ink according to the second printing data is completed, the metal ink 336 is printed on the resin layered body 330 as shown in FIG. 24 .

As described above, in the modeling work machine 152 of the work system 150, similarly to the modeling apparatus 10, it is possible to print the metal ink according to the printing data according to the setting direction of the pallet 70. A similar effect can be obtained. Further, in the work system 150 , the mounting work machine 154 mounts the electronic component 340 on the resin laminate 330 formed by the molding work machine 152 . At this time, in the mounting work machine 154, the pallet 70 is imaged by the camera 268, and the mounting position of the electronic component 340 is determined based on the imaging data obtained by the imaging.

Specifically, in the modeling work machine 152, when the inkjet head 208 prints the metal ink according to the printing data corresponding to the setting direction of the pallet 70, the infrared irradiation device 204 irradiates the metal ink with infrared rays to produce wiring. is formed. Then, the pallet is carried out from the modeling work machine 152 and carried into the mounting work machine 154 . Subsequently, in the mounting work machine 154 , when the pallet is conveyed to the work position by the conveying device 260 and held by the board holding device 276 , the camera 268 takes an image of the pallet. Then, the controller 310 of the control device 270 calculates the positions of the three reference marks 110 based on the imaging data.

Also, in the controller 310, the mounting position of the electronic component according to the position of the reference mark 110 is set. Specifically, when the three reference marks 110 are at the positions shown in FIG. 25, that is, when the pallet setting direction is the first setting direction, the mounting position A (X1, Y1) of the electronic component 340 is is set. When the three reference marks 110 are at the positions shown in FIG. 26, that is, when the pallet setting direction is the second setting direction, the mounting position B (X2, Y2) of the electronic component 340 is set. there is The mounting position A (X1, Y1) is set at a position where the wiring 338 formed by the metal ink printed according to the first printing data contacts the electrode 342 of the electronic component 340 . On the other hand, the mounting position B (X2, Y2) is set at a position where the wiring 338 formed by the metal ink printed according to the second printing data contacts the electrode 342 of the electronic component 340 . Then, when it is calculated that the three reference marks 110 are at the positions shown in FIG. 25 based on the imaging data, the electronic component is mounted at the mounting position A (X1, Y1). On the other hand, when it is calculated that the three reference marks 110 are at the positions shown in FIG. 26 based on the imaging data, the electronic component is mounted at the mounting position B (X2, Y2). Accordingly, the electronic component 340 can be mounted at an appropriate position regardless of whether the pallet is set in the first set direction or the second set direction.

Also, by using the set direction of the pallet specified by the molding work machine 152, the electronic component 340 can be mounted at an appropriate position on the mounting work machine. Specifically, the mounting position A (X1, Y1) and the mounting position B (X2, Y2) are stored in the storage device 256 of the modeling work machine 152, and the mounting position A (X1, Y1) and the first set are stored. The mounting position B (X2, Y2) and the second set direction are associated with each other. Then, when the molding work machine 152 determines that the pallet setting direction is the first set direction, the control device 172 of the molding work machine 152 sets the mounting position A (X1 , Y1) to the control device 270 of the mounting work machine 154 . On the other hand, when the molding work machine 152 determines that the pallet setting direction is the second set direction, the controller 172 of the molding work machine 152 controls the mounting position B (X2 , Y2) to the controller 270 of the mounting work machine 154 . Then, the control device 270 of the mounting work machine 154 mounts the electronic component 340 at the mounting position received from the control device 172 of the modeling work machine 152 . As a result, the electronic component 340 can be mounted at an appropriate position without imaging the pallet by the camera 268 in the mounting work machine 154, and the imaging time by the camera 268 can be shortened.

Also, the controller 250 of the control device 172 of the modeling work machine 152 has a determination section 350, a data creation section 352, and a printing section 354, as shown in FIG. The determination unit 350 is a functional unit for determining whether the pallet setting direction is the first setting direction or the second setting direction based on the imaging data. The data creation unit 352 is a functional unit for creating the second print data based on the first print data.

Also, in the above embodiment, the pallets are set on the

stages

52 and 182 in either the first or second posture. That is, the pallet is set in a predetermined posture and a posture obtained by rotating the predetermined posture by 180 degrees. On the other hand, the pallet may be set in a predetermined posture and a posture obtained by rotating the predetermined posture by an angle other than 180 degrees. For example, the pallet may be set in a predetermined orientation and an orientation obtained by rotating the predetermined orientation by an angle that is a multiple of 90 degrees. In such a case, printing data is required for printing a viscous fluid such as an ultraviolet curable resin on a pallet that is set in a posture rotated by an angle that is a multiple of 90 degrees from a predetermined posture. Furthermore, the pallet may be set on the

stage

52, 182 at any angle of rotation. In such a case, it is necessary to calculate the rotation angle of the pallet and print data for printing viscous fluid such as ultraviolet curable resin on the pallet set at that rotation angle.
