The second component recognition image acquired by the third imaging unit 33 is used for determining the drop of the component from the suction nozzle 2511.

[About the data creation device]
The arrangement position of the push-up pin 282 on the push-up plate 281 in the board support device 28 is set for each type of the board PP. Therefore, when the product type of the board PP to which the component is mounted is switched in the mounting machine 2, the arrangement of the push-up pin 282 is changed. The rearrangement of the push-up pin 282 on the push-up plate 281 is performed by the mounting head 251 of the head unit 25.

The data creation device 5 is connected to the system management device 4 so as to be capable of data communication, and is composed of, for example, a microcomputer. The data creation device 5 is a device that creates recommended placement data RD indicating the recommended placement position of the push-up pin 282 on the push-up plate 281. The recommended placement data RD created by the data creation device 5 is transmitted to the system management device 4. When the system management device 4 receives the recommended placement data RD, the system management device 4 updates the control data CD reflecting the contents of the recommended placement data RD. The control data CD reflecting the recommended placement data RD is transmitted to the mounting machine 2. In the mounting machine 2, when switching the product type of the substrate PP, the mounting head 251 changes the arrangement of the push-up pin 282 based on the control data CD in which the recommended arrangement data RD is reflected. That is, the mounting head 251 changes the arrangement of the push-up pins 282 based on the recommended arrangement data RD.

As shown in FIG. 1, the data creation device 5 includes a data acquisition unit 51, a storage unit 52, and a data creation unit 53.

The data acquisition unit 51 acquires the management data MD transmitted from the system management device 4. The management data MD acquired by the data acquisition unit 51 will be described with reference to FIG. The management data MD is data for managing the production of the board PP in the component mounting system 1. In the management data MD, the data set DS of the substrate PP scheduled to be produced in a predetermined period (for example, one day) is registered. The data set DS includes a plurality of data group DGs, and a plurality of substrate product types PPT are registered in each data group DG. In the example of FIG. 5, the data set “DS1” includes a data group “1” and a data group “2”. Then, three types of board PPs represented by the board types "A", "B", and "C" are registered in the data group "1", and the board types "D" and "E" are registered in the data group "2". , Three types of substrate PPs indicated by "F" are registered.

Further, in the management data MD, the production order PO, the system operating time OT, the system preparation time ST, and the total production time TT are registered.

The production order PO is data indicating the production order of each substrate PP of the substrate product type PPT belonging to a plurality of data groups DG. In the example of FIG. 5, the substrate types "A", "B", "C", "D", "E", " Production of substrate PP proceeds in the order of "F".

The system operating time OT is data indicating the actual operating time of the mounting machine 2 and the processing machine 3 for each data group DG when the substrate PP is produced in the order indicated by the production order PO. In the example of FIG. 5, the actual operating time of the mounting machine 2 and the processing machine 3 when producing the board PPs of the board types “A”, “B”, and “C” belonging to the data group “1” is “TO1”. Is shown to be. Similarly, the actual operating time of the mounting machine 2 and the processing machine 3 when producing the board PPs of the board types “D”, “E”, and “F” belonging to the data group “2” is “TO2”. It is shown that.

When the substrate type PPT belonging to each data group DG is changed, the system operating time OT shows a different value according to the change. For example, a system corresponding to the data group "1" depending on whether the substrate types belonging to the data group "1" are "A", "B", "C" or "A", "B". The operating time OT shows different values. Similarly, when the substrate types belonging to the data group "2" are "D", "E", and "F", and when they are "C", "D", "E", and "F", The system operating time OT corresponding to the data group "2" shows different values.

The system preparation time ST is data indicating the preparation time required for the preparation process in the entire component mounting system 1 that may occur in response to the switching of the board type PPT for each board type PPT. The system preparation time ST includes the mounting machine preparation time MT and the processing machine preparation time PT. The processing machine preparation time PT is the preparation time required for the preparation processing of the processing machine 3. The preparatory process of the processing machine 3 includes, for example, a process of preparing a screen mask to be used when printing a solder paste pattern on the substrate PP. The mounting machine preparation time MT is the preparation time required for the preparation process of the mounting machine 2. The preparation process of the mounting machine 2 includes, for example, a process of changing the arrangement of the push-up pin 282, a process of replacing the feeder 24F mounted on the component supply unit 24, a process of replacing the suction nozzle 2511 mounted on the mounting head 251 and the like. included.

The system preparation time ST is specified by the longest value among the mounting machine preparation time MT and the processing machine preparation time PT. For example, when the time required for the screen mask preparation process in the processing machine 3 is the longest among the mounting machine preparation time MT and the processing machine preparation time PT, that time is the system preparation time ST. Similarly, when the time required for the replacement process of the feeder 24F in the mounting machine 2 is the longest value among the mounting machine preparation time MT and the processing machine preparation time PT, that time is the system preparation time ST.

When the substrate type PPT belonging to each data group DG is changed, the system preparation time ST shows a different value according to the change. For example, when the board types belonging to the data group "1" are "A", "B", and "C", and when the board types are "A", "B", the system preparation time ST for each board type PPT. Indicates different values. Similarly, when the substrate types belonging to the data group "2" are "D", "E", and "F", and when they are "C", "D", "E", and "F", The system preparation time ST for each substrate type PPT shows different values.

The total production time TT is data indicating the total time required for the production of all the substrate PPs of the substrate product types PPT belonging to the plurality of data groups DG included in the data set DS. The total production time TT is the sum of the added values of the system operating time OT and the system preparation time ST for each data group DG in the data set DS.

As described above, the system operating time OT and the system preparation time ST show different values according to the change when the substrate type PPT belonging to each data group DG is changed. Therefore, when the substrate type PPT belonging to each data group DG is changed, the total production time TT based on the system operating time OT and the system preparation time ST also shows different values according to the change. In view of this, the substrate type PPT belonging to each data group DG constituting the data set DS is determined so that the total production time TT is the shortest.

Next, the storage unit 52 and the data creation unit 53 provided in the data creation device 5 will be described with reference to FIGS. 6 to 8 in addition to FIG. In the following description with reference to FIGS. 6 to 8, the position on the push-up plate 281 may be indicated by using XY coordinates. Specifically, the upper surface of the push-up plate 281 is divided into nine regions in the X-axis direction and six regions in the Y-axis direction, and the positions on the push-up plate 281 are indicated by a total of 54 XY coordinate positions. For example, in the plan view of the push-up plate 281, the position of the lower left corner is expressed as coordinates (1,1), the position of the lower right corner is expressed as coordinates (9,1), and the position of the upper left corner is expressed as coordinates. It is expressed as (1,6), and the position of the upper right corner is expressed as coordinates (9,6).

The storage unit 52 stores the reference arrangement data SD indicating the reference arrangement of the push-up pins 282 on the push-up plate 281 for each substrate type PPT. The reference arrangement data SD is data unique to each substrate type PPT. As shown in FIGS. 6 to 8, the reference arrangement data SD divides the required position SD1, the prohibited position SD2, and the selectable position SD3 as the reference arrangement of the push-up pin 282 on the push-up plate 281. It is the data to show.

The required position SD1 is a position on the push-up plate 281 where the push-up pin 282 needs to be arranged to support the substrate PP. In FIGS. 6 to 8, the required position SD1 is indicated by a “black circle”. The required position SD1 is different for each substrate type PPT. The prohibited position SD2 is a position on the push-up plate 281 that prohibits the placement of the push-up pin 282. In FIGS. 6 to 8, the prohibited position SD2 is indicated by a “circle with a cross”. The prohibited position SD2 is different for each substrate type PPT. The selectable position SD3 is a position on the push-up plate 281 that can be appropriately selected depending on whether or not the push-up pin 282 needs to be arranged. In FIGS. 6-8, the selectable position SD3 is indicated by a "diagonal circle". The selectable position SD3 is different for each substrate type PPT.

The reference arrangement data SD for each board type PPT is referred to when the data creation unit 53 creates the recommended arrangement data RD.

The data creation unit 53 creates recommended placement data RD for each substrate type PPT corresponding to the plurality of reference placement data SDs based on the plurality of reference placement data SDs. In FIG. 6, the data creation unit 53 uses the substrate types “A”, “B”, and “ Create recommended placement data RD corresponding to each of "C". Further, in FIGS. 7 and 8, the data creation unit 53 uses the substrate types "D" and "D" and "F." Create recommended placement data RD corresponding to each of "E" and "F".

The recommended placement data RD is data indicating the recommended placement position RD1 of the push-up pin 282 on the push-up plate 281. In FIGS. 6-8, the recommended placement position RD1 is indicated by a "double circle". The data creation unit 53 calculates the value of the influential factor that affects the efficiency of the arrangement change of the push-up pin 282 according to the switching of the substrate type PPT, and recommends that the value of the influential factor becomes the recommended value. Create placement data RD.

The data creation unit 53 does not create the recommended layout data RD in consideration of the layout change of the push-up pin 282 at the time of switching the substrate type PPT once corresponding to one reference layout data SD. The data creation unit 53 creates the recommended layout data RD in consideration of the layout change of the push-up pin 282 at the time of switching the substrate product type PPT a plurality of times corresponding to the plurality of reference layout data SDs. The recommended layout data RD for each substrate type PPT corresponding to the plurality of reference arrangement data SD makes it possible to efficiently change the arrangement of the push-up pin 282 at the time of switching the substrate type PPT.

As shown in FIG. 6, the data creation unit 53 executes a common layout process for creating a common recommended layout data RD for a plurality of substrate product types PPT corresponding to a plurality of reference layout data SDs. In this case, the recommended placement position RD1 of the push-up pin 282 on the push-up plate 281 is common to the plurality of substrate product types PPT. After switching one board type (for example, board type "A") by the recommended arrangement data RD common to a plurality of board types PPT, another board type (for example, board type "B", "C") When switching to, the rearrangement change of the push-up pin 282 can be omitted. Therefore, it is possible to improve the efficiency of changing the arrangement of the push-up pins 282 when switching the substrate type PPT.

Depending on the positional relationship of each reference arrangement of the push-up pins 282 indicated by the plurality of reference arrangement data SDs, it may not be possible to create a common recommended arrangement data RD among a plurality of substrate product types PPT. In this case, as shown in FIGS. 7 and 8, the data creation unit 53 executes a separate placement process for creating a separate recommended placement data RD for a plurality of board type PPTs corresponding to the plurality of reference placement data SDs. In this case, the recommended placement position RD1 of the push-up pin 282 on the push-up plate 281 is different in each of the plurality of substrate product types PPT. In the recommended placement data RD separately for multiple board types PPT, the placement position of the push-up pin 282 is set so that the value of the influencing factor that affects the efficiency of the placement change of the push-up pin 282 is the recommended value. It has been adjusted. Therefore, although it is necessary to change the arrangement of the push-up pins 282 every time the substrate type PPT is switched, the arrangement can be changed efficiently.

The data creation unit 53 is configured to calculate the number of pin movements as an influential factor in the separate placement process and create the recommended placement data RD so that the number of pin movements becomes a recommended value (for example, the minimum number of pin movements). To. The number of pin movements indicates the total number of push-up pins 282 to be moved when the arrangement of the push-up pins 282 is changed according to the switching of the substrate type PPT. The number of pin movements is an influential factor that affects the efficiency of rearranging the push-up pins 282. That is, as the number of push-up pins 282 to be moved at the time of the arrangement change decreases, the efficiency of the arrangement change increases. Since the recommended placement data RD is created so that the number of pin movements, which is an influence factor of the efficiency of the placement change, becomes the recommended value, the recommended placement data RD pushes up when switching the substrate type PPT. It is possible to efficiently change the arrangement of the pins 282.

Further, the data creation unit 53 calculates the pin arrangement change time as an influential factor in the separate arrangement process, and creates the recommended arrangement data RD so that the pin arrangement change time becomes a recommended value (for example, the shortest pin arrangement change time). It may be configured to do so. The pin arrangement change time indicates the total time of movement of the push-up pin 282 when the arrangement of the push-up pin 282 is changed according to the change of the substrate type PPT. The pin arrangement change time is an influential factor that affects the efficiency of the arrangement change of the push-up pin 282. That is, as the pin arrangement change time, which indicates the total time of movement of the push-up pin 282 at the time of arrangement change, becomes shorter, the efficiency of the arrangement change increases. Since the recommended placement data RD is created so that the pin placement change time, which is an influence factor of the efficiency of the placement change, becomes the recommended value, the recommended placement data RD is used to push when switching the substrate type PPT. It is possible to efficiently change the arrangement of the uppin 282.

Further, the data creation unit 53 calculates the pin movement distance as an influential factor in the separate placement process, and creates the recommended placement data RD so that the pin movement distance becomes a recommended value (for example, the shortest pin movement distance). It may be configured. The pin movement distance indicates the total distance of movement of the push-up pin 282 when the arrangement of the push-up pin 282 is changed according to the switching of the substrate type PPT. The pin movement distance is an influential factor that affects the efficiency of the rearrangement of the push-up pin 282. That is, as the moving distance of the push-up pin 282 at the time of the arrangement change becomes shorter, the efficiency of the arrangement change increases. Since the recommended placement data RD is created so that the pin movement distance, which is an influence factor of the efficiency of the placement change, becomes the recommended value, the recommended placement data RD pushes up when switching the substrate type PPT. It is possible to efficiently change the arrangement of the pins 282.

Further, as shown in FIG. 7, the data creation unit 53 may be configured to calculate the value of the influential factor assuming the movement of the push-up pin 282 from the pin station 29 to the push-up plate 281. .. Then, the data creation unit 53 creates the recommended placement data RD so that the calculated value of the influential factor becomes the recommended value. With such recommended arrangement data RD, it is possible to efficiently change the arrangement of the push-up pin 282 at the time of switching the substrate type PPT in consideration of the existence of the pin station 29.

In the example of FIG. 7, in the recommended placement data RD corresponding to the substrate type “D”, the coordinates (2, 2) and the coordinates (3, 2) are set as the recommended placement positions RD1 of the push-up pin 282 on the push-up plate 281. ), Coordinates (4,2), Coordinates (5,2), Coordinates (6,2), Coordinates (7,2), Coordinates (8,2), Coordinates (2,5), Coordinates (3,5) , Coordinates (4,5), coordinates (5,5), coordinates (6,5), coordinates (7,5), and coordinates (8,5) are set respectively. These recommended placement positions RD1 include the required position SD1 in the reference placement data SD corresponding to the substrate type “D”, and do not include the prohibited position SD2.

In the recommended placement data RD corresponding to the board type "E", the coordinates (2,1), coordinates (8,1), and coordinates (2,) are set as the recommended placement position RD1 of the pushup pin 282 on the pushup plate 281. 2), coordinates (5,2), coordinates (8,2), coordinates (2,3), coordinates (5,3), coordinates (8,3), coordinates (2,4), coordinates (5,4) ), Coordinates (8,4), coordinates (2,5), coordinates (5,5), coordinates (8,5), coordinates (2,6), and coordinates (8,6) are set respectively. These recommended placement positions RD1 include the required position SD1 in the reference placement data SD corresponding to the substrate type “E”.

In the recommended placement data RD corresponding to the board type "F", the coordinates (2,2), coordinates (3,2), and coordinates (5,) are set as the recommended placement position RD1 of the pushup pin 282 on the pushup plate 281. 2), coordinates (7,2), coordinates (8,2), coordinates (2,3), coordinates (5,3), coordinates (8,3), coordinates (2,4), coordinates (5,4) ), Coordinates (8,4), coordinates (2,5), coordinates (3,5), coordinates (5,5), coordinates (7,5), coordinates (8,5), respectively. These recommended placement positions RD1 include the required position SD1 in the reference placement data SD corresponding to the substrate type "F", and do not include the prohibited position SD2.

In the example of FIG. 7, when the type is switched from the board type “D” to the board type “E”, 10 push-up pins 282 are moved as a change in the arrangement of the push-up pins 282 based on the recommended arrangement data RD. .. Specifically, the push-up pin 282 is moved from the pin station 29 to the recommended placement position RD1 of the coordinates (2, 6) and the coordinates (8, 6) on the push-up plate 281. Next, among the push-up pins 282 arranged at the recommended arrangement position RD1 on the push-up plate 281 based on the recommended arrangement data RD corresponding to the substrate type "D", the push-up pins having coordinates (3, 5). 282 is moved to coordinates (2,4). Similarly, the push-up pin 282 at coordinates (4,5) is moved to coordinates (5,4), the push-up pin 282 at coordinates (7,5) is moved to coordinates (8,4), and coordinates (4). , 2) push-up pin 282 is moved to coordinate (2,3), coordinate (6,2) push-up pin 282 is moved to coordinate (5,3), and coordinate (6,5) push-up. The pin 282 is moved to the coordinates (8,3), the push-up pin 282 at the coordinates (3,2) is moved to the coordinates (2,1), and the push-up pin 282 at the coordinates (7,2) is moved to the coordinates (8). , 1).

Further, when the type is switched from the board type "E" to the board type "F", the four push-up pins 282 are moved as the arrangement change of the push-up pins 282 based on the recommended arrangement data RD. Specifically, among the push-up pins 282 arranged at the recommended arrangement position RD1 on the push-up plate 281 based on the recommended arrangement data RD corresponding to the substrate type "E", the coordinates (2, 6) are pushed. Uppin 282 is moved to coordinates (3,5). Similarly, the push-up pin 282 at coordinates (8, 6) is moved to coordinates (7, 5), the push-up pin 282 at coordinates (2, 1) is moved to coordinates (3, 2), and coordinates (8). , 1) The push-up pin 282 is moved to the coordinates (7, 2).

Further, as shown in FIG. 8, the data creation unit 53 provides all the push-up pins 282 necessary for supporting the substrate PPs of a plurality of types corresponding to the plurality of reference arrangement data SDs in the separate arrangement processing. , The value of the influential factor may be calculated assuming the arrangement of all the pins arranged on the push-up plate 281 with the arrangement change for each substrate type PPT. Then, the data creation unit 53 creates the recommended placement data RD so that the calculated value of the influential factor becomes the recommended value. In the all-pin arrangement, all push-up pins 282 required to support each of the plurality of types of substrate PPs are arranged on the push-up plate 281. In this case, when the arrangement of the push-up pin 282 is changed, it is only necessary to move the push-up pin 282 on the push-up plate 81. As a result, the moving distance of the push-up pin 282 at the time of the rearrangement change can be shortened, so that the efficiency of the rearrangement change of the push-up pin 282 can be improved.

When the data creation unit 53 creates the recommended layout data RD of one board PP corresponding to one reference layout data SD among the plurality of reference layout data SDs in the case where all pin layouts are assumed, the following Perform separate placement processing as in. That is, the data creation unit 53 selects the required position SD1 in one reference arrangement data SD as the arrangement position of the push-up pin 282 that supports one substrate PP. As a result, one substrate PP can be appropriately supported by the push-up pin 282 arranged at the required position SD1. Further, the data creation unit 53 selects the selectable position SD3 in one reference arrangement data SD as a temporary arrangement position of the push-up pin 282 that supports another substrate PP other than one substrate PP. That is, when supporting one substrate PP, the push-up pins 282 for the other substrate PP are not temporarily arranged at the prohibited position SD2, but are temporarily arranged at the selectable position SD3. This allows the push-up pins 282 for the other substrate PP to be tentatively placed on the push-up plate 281 while maintaining proper support for one substrate PP.

Further, the data creation unit 53 has a pair of conveyor rails 23 arranged above the push-up plate 281 when creating the recommended arrangement data RD of one substrate PP in the case where all pin arrangements are assumed. Consider. Specifically, the data creation unit 53 sets the push-up pin 282 supporting the other substrate PP on the push-up plate 281 in the selectable position SD3 in one reference arrangement data SD as a temporary arrangement position. The one located in the inner region of the pair of conveyor rails 23 is selected. This avoids interference with the pair of conveyor rails 23 when moving the push-up pins 282 when changing the arrangement of the push-up pins 282 according to the switching of the product type from one board PP to another board PP. You don't have to move it while doing it. Therefore, the efficiency of changing the arrangement of the push-up pins 282 can be improved.

Further, the data creation unit 53 is configured to sequentially create recommended arrangement data RD for each substrate type PPT according to the switching order of the substrate PP types (corresponding to the production order PO registered in the management data MD). Then, when the data creation unit 53 changes the switching order so that the value of the influential factor tends to improve the efficiency of changing the arrangement of the push-up pins 282 according to the switching of the substrate product type PPT, the data creation unit 53 said. The order of creating the recommended placement data RD is changed according to the change of the switching order. In the example of FIG. 8, according to the production order PO registered in the management data MD, the switching order of the board type PPT is in the order of the board types “D”, “E”, “F”, but the switching order is The board types are changed in the order of "D", "F", and "E". In this case, the data creation unit 53 changes the creation order of the recommended layout data RD to the order corresponding to the board types “D”, “F”, and “E”.

As described above, when the data creation unit 53 can improve the efficiency of the arrangement change of the push-up pin 282 by changing the switching order of the board type PPT, the data creation unit 53 recommends the arrangement data according to the change of the switching order. Change the creation order of RD. As a result, after changing the switching order of the substrate product type PPT, it is possible to improve the efficiency of changing the arrangement of the push-up pins 282 according to the product type switching.

In the example of FIG. 8, in the recommended arrangement data RD corresponding to the substrate type “D”, the coordinates (2,2) and the coordinates (3,2) are set as the recommended arrangement position RD1 of the pushup pin 282 on the pushup plate 281. ), Coordinates (4,2), Coordinates (5,2), Coordinates (7,2), Coordinates (8,2), Coordinates (2,5), Coordinates (3,5), Coordinates (4,5) , Coordinates (5,5), coordinates (7,5), and coordinates (8,5) are set respectively. These recommended placement positions RD1 include the required position SD1 in the reference placement data SD corresponding to the substrate type “D”, and do not include the prohibited position SD2.

In the recommended placement data RD corresponding to the board type "F", the coordinates (2,2), coordinates (5,2), and coordinates (8,) are set as the recommended placement position RD1 of the pushup pin 282 on the pushup plate 281. 2), coordinates (2,3), coordinates (5,3), coordinates (8,3), coordinates (2,4), coordinates (5,4), coordinates (8,4), coordinates (2,5) ), Coordinates (5,5), and coordinates (8,5) are set respectively. These recommended placement positions RD1 include the required position SD1 in the reference placement data SD corresponding to the substrate type "F", and do not include the prohibited position SD2.

In the recommended placement data RD corresponding to the board type "E", the coordinates (2,1), coordinates (8,1), and coordinates (5,) are set as the recommended placement position RD1 of the pushup pin 282 on the pushup plate 281. 2), coordinates (2,3), coordinates (5,3), coordinates (8,3), coordinates (2,4), coordinates (5,4), coordinates (8,4), coordinates (5,5) ), Coordinates (2,6), and coordinates (8,6) are set respectively. These recommended placement positions RD1 include the required position SD1 in the reference placement data SD corresponding to the substrate type “E”.

In the example of FIG. 8, when the type is switched from the substrate type “D” to the substrate type “F”, the six push-up pins 282 are moved as the arrangement change of the push-up pins 282 based on the recommended arrangement data RD. .. Specifically, among the push-up pins 282 arranged at the recommended arrangement position RD1 on the push-up plate 281 based on the recommended arrangement data RD corresponding to the substrate type "D", the coordinates (3, 5) are pushed. Uppin 282 is moved to coordinates (2,4). Similarly, the push-up pin 282 at coordinates (4,5) is moved to coordinates (5,4), the push-up pin 282 at coordinates (7,5) is moved to coordinates (8,4), and coordinates (3). , 2) push-up pin 282 is moved to coordinate (2,3), coordinate (4,2) push-up pin 282 is moved to coordinate (5,3), and coordinate (7,2) push-up. Pin 282 is moved to coordinates (8,3).

Further, when the type is switched from the board type "F" to the board type "E", the four push-up pins 282 are moved as the arrangement change of the push-up pins 282 based on the recommended arrangement data RD. Specifically, among the push-up pins 282 arranged at the recommended arrangement position RD1 on the push-up plate 281 based on the recommended arrangement data RD corresponding to the substrate type "F", the coordinates (2, 5) are pushed. Uppin 282 is moved to coordinates (2,6). Similarly, the push-up pin 282 at coordinates (8, 5) is moved to coordinates (8, 6), the push-up pin 282 at coordinates (2, 2) is moved to coordinates (2, 1), and coordinates (8). , 2) The push-up pin 282 is moved to the coordinates (8, 1).

Next, with reference to the flowchart of FIG. 9, the processing flow when the data creation unit 53 creates the recommended placement data RD will be described.

First, the data creation unit 53 tries the common arrangement process for all the board type PPTs in the data set DS based on the management data MD acquired by the data acquisition unit 51 (step S1). The data creation unit 53 determines whether or not the common recommended allocation data RD can be created by this common allocation process (step S2). When the common recommended arrangement data RD can be created (YES in step S2), the data creation unit 53 ends the data creation process. In this case, the arrangement of the push-up pin 282 is changed by the mounting head 251 based on the recommended arrangement data RD common to all the substrate product types PPT in the data set DS.

On the other hand, when it is impossible to create the recommended layout data RD common to all the board product types PPT in the data set DS (NO in step S2), the data creation unit 53 shifts the process to step S3. In step S3, the data creation unit 53 tries the common arrangement process for the substrate type PPT in the data group DG. The data creation unit 53 determines whether or not the common recommended allocation data RD can be created by this common allocation process (step S4). When it is possible to create the common recommended placement data RD (YES in step S4), the data creation unit 53 calculates the number of common recommended placement data RDs to be created when the order of the data group DG is changed (step). S6), and then the process proceeds to step S7.

On the other hand, when it is impossible to create the recommended layout data RD common to the board type PPT in the data group DG (NO in step S4), the data creation unit 53 is the production sequence PO in the data group DG. The number of common recommended placement data RDs to be created at the time of change is calculated (step S5), and then the process shifts to step S7.

In step S7, the data creation unit 53 tries the separate placement process for the substrate type PPT that is not the target of the common placement process. The data creation unit 53 creates a separate recommended placement data RD for the substrate type PPT that is the target of this separate placement processing. After that, the data creation unit 53 determines whether or not the separate placement process is completed (step S8), and ends the creation process of the recommended placement data RD when the separate placement process is completed.

Next, the operation of the data creation unit 53 when creating the recommended placement data RD in consideration of the system preparation time ST registered in the management data MD acquired by the data acquisition unit 51 will be described with reference to FIG. do. In FIG. 10, the processing machines 3 and the mounting machines 2 constituting the component mounting system 1 sequentially produce each board PP having the board types PPT belonging to the same data group DG as “A”, “B”, and “C”. The scene is illustrated.

When the management data MD is acquired by the data acquisition unit 51, the data creation unit 53 recommends it by setting the recommended value of the influential factor so that the system preparation time ST registered in the management data MD is the shortest. Create placement data RD. As a result, by increasing the efficiency of changing the arrangement of the push-up pins 282 according to the switching of the board type PPT, it is possible to improve the efficiency of the entire preparation process of the component mounting system 1 represented by the system preparation time ST. can. As the value of the influential factor in this case, any one of the above-mentioned "number of pin movements", "pin arrangement change time", and "pin movement distance" is used.

Specifically, as shown in FIG. 10, in the system preparation time ST in the initial setting state registered in the management data MD, the average value of the processing machine preparation time PT for each substrate type PPT is the mounting machine preparation time MT. When the time is longer than the average value, the data creation unit 53 operates as follows. That is, the data creation unit 53 sets the pin arrangement change time required for the arrangement change of the push-up pin 282 as the value of the influential factor, and sets the recommended value of the pin arrangement change time to a value close to the processing machine preparation time PT. , Create recommended placement data RD.

More specifically, the data creation unit 53 extracts the longest value in each mounting machine preparation time MT for each board type PPT. In the example of FIG. 10, the mounting machine preparation time MT of the board type “C” shows the longest value. Then, the data creation unit 53 sets the recommended value of the pin arrangement change time at the time of changing the arrangement of the push-up pin 282 according to the switching of the board type PPT corresponding to the longest value to a value close to the processing machine preparation time PT. By doing so, the recommended placement data RD is created.

When the average value of the processing machine preparation time PT for each board type PPT is longer than the average value of the mounting machine preparation time MT, the system preparation time ST of the entire component mounting system 1 at the time of switching the board type PPT is processed. Machine preparation time Determined by PT. That is, even if the pin arrangement change time included in the mounting machine preparation time MT is set to an extremely short time, it does not contribute to the efficiency of the preparation processing of the entire component mounting system 1. In other words, it is sufficient that the pin arrangement change time is set to a value close to the processing machine preparation time PT. Such setting of the pin arrangement change time does not reduce the efficiency of the preparation process of the entire component mounting system 1.

The specific embodiments described above mainly include inventions having the following configurations.

According to this data creation device, the data creation unit creates recommended placement data indicating the recommended placement position of the push-up pin on the push-up plate based on a plurality of reference placement data unique to each type of substrate. That is, the data creation unit does not create the recommended placement data in consideration of the change in the placement of the push-up pins at the time of switching the board type once corresponding to one reference placement data. The data creation unit creates recommended layout data in consideration of the push-up pin layout change at the time of switching the board product a plurality of times corresponding to the plurality of reference layout data. With such recommended layout data for each type of substrate corresponding to a plurality of reference arrangement data, it is possible to efficiently change the arrangement of push-up pins when switching between substrate types.

In the above data creation device, the data creation unit executes a common arrangement process for creating the recommended arrangement data common to a plurality of types of the substrate corresponding to the plurality of reference arrangement data.

In this aspect, the recommended layout data common to multiple types of boards is created by the common layout processing by the data creation unit. With such recommended layout data common to a plurality of board types, it is possible to omit the push-up pin placement change when switching to another board type after switching one board type. Therefore, it is possible to improve the efficiency of changing the arrangement of the push-up pins when switching the substrate type.

In the data creation device, the data creation unit executes a separate placement process for creating separate recommended placement data for a plurality of types of the substrate corresponding to the plurality of reference placement data.

Depending on the positional relationship of each reference arrangement of the push-up pins shown by multiple reference arrangement data, it may not be possible to create common recommended arrangement data for multiple types of boards. In this case, the separate placement process by the data creation unit creates separate recommended placement data for multiple types of boards. The recommended placement data for multiple types of boards are those in which the placement position of the push-up pin is adjusted so that the value of the influential factor that affects the efficiency of the push-up pin placement change is the recommended value.

In the above data creation device, the data creation unit determines the total number of the push-up pins to be moved when the arrangement of the push-up pins is changed according to the switching of the type of the substrate in the separate arrangement process. The number of pin movements shown is calculated as the value of the influence factor, and the recommended arrangement data is created so that the number of pin movements becomes the recommended value.

In this aspect, the data creation unit creates recommended placement data so that the number of pin movements when changing the placement of push-up pins is the recommended value. The number of pin movements is an influential factor that affects the efficiency of changing the arrangement of push-up pins. That is, as the number of push-up pins to be moved when changing the arrangement decreases, the efficiency of the arrangement change increases. Since the recommended placement data is created so that the number of pin movements, which is an influence factor of the efficiency of the placement change, is the recommended value, the push-up pin placement when switching the board type is based on this recommended placement data. It is possible to make changes efficiently.

In the above data creation device, the data creation unit determines the total time of movement of the push-up pins when the arrangement of the push-up pins is changed according to the switching of the product type of the substrate in the separate arrangement process. The indicated pin arrangement change time is calculated as the value of the influence factor, and the recommended arrangement data is created so that the pin arrangement change time becomes the recommended value.

In this aspect, the data creation unit creates recommended placement data so that the pin placement change time when changing the push-up pin placement is the recommended value. The pin placement change time is an influential factor that affects the efficiency of the push-up pin placement change. That is, the efficiency of the arrangement change increases as the pin arrangement change time, which indicates the total time of the push-up pin movement at the time of changing the arrangement of the push-up pins, becomes shorter. Since the recommended placement data is created so that the pin placement change time, which is an influence factor of the efficiency of the placement change, is the recommended value, the recommended placement data can be used to switch the push-up pin when switching the board type. It is possible to efficiently change the layout.

In the above data creation device, the data creation unit determines the total distance of movement of the push-up pins when the arrangement of the push-up pins is changed according to the switching of the product type of the substrate in the separate arrangement process. The indicated pin movement distance is calculated as the value of the influential factor, and the recommended placement data is created so that the pin movement distance becomes the recommended value.

In this aspect, the data creation unit creates recommended placement data so that the pin movement distance when changing the placement of the push-up pin becomes the recommended value. The pin movement distance is an influential factor that affects the efficiency of changing the position of the push-up pin. That is, as the moving distance of the push-up pin at the time of the arrangement change becomes shorter, the efficiency of the arrangement change increases. Since the recommended placement data is created so that the pin movement distance, which is an influence factor of the efficiency of the placement change, becomes the recommended value, the push-up pin placement when switching the board type is based on this recommended placement data. It is possible to make changes efficiently.

In the above data creation device, the data creation unit assumes the movement of the push-up pin from the pin station for storing the push-up pin to the push-up plate in the separate arrangement process, and the value of the influence factor. Is calculated, and the recommended placement data is created so that the value of the influential factor becomes the recommended value.

In this aspect, the data creation unit creates recommended placement data assuming the movement of the push-up pin from the pin station to the push-up plate. With such recommended placement data, it is possible to efficiently change the placement of push-up pins when switching board types, taking into consideration the existence of pin stations.

In the above data creation device, the data creation unit performs all the push-up pins necessary for supporting each of the plurality of types of substrates corresponding to the plurality of reference arrangement data in the separate arrangement process. The value of the influential factor is calculated assuming all the pin arrangements to be arranged on the push-up plate with the arrangement change for each type of the substrate, and the recommended value is set to the recommended value. Create placement data.

In this aspect, the data creation unit creates recommended layout data assuming all pin layouts in which all push-up pins required to support multiple types of substrates are placed on the push-up plate. In the all-pin arrangement, all push-up pins required to support each of the plurality of types of substrates are arranged on the push-up plate. In this case, when changing the arrangement of the push-up pins, it is only necessary to move the push-up pins on the push-up plate. This makes it possible to shorten the moving distance of the push-up pins when changing the arrangement, so that the efficiency of changing the arrangement of the push-up pins can be improved.

In the above data creation device, the reference arrangement data is the necessary position where the push-up pin arrangement is required and the push-up as the reference arrangement for each type of the substrate of the push-up pin on the push-up plate. It is data which shows the division of the prohibition position which prohibits the arrangement of a pin, and the selectable position which can be appropriately selected about the necessity of the arrangement of a push-up pin. Then, when the data creation unit assumes the all pin arrangement and creates the recommended arrangement data of one board corresponding to one reference arrangement data among the plurality of reference arrangement data, the data creation unit may create the recommended arrangement data. As the placement position of the push-up pin that supports the one board, the required position in the reference placement data of the one is selected, and the temporary placement of the push-up pin that supports the other boards other than the one board is tentatively arranged. As the position, the selectable position in the reference arrangement data of the one is selected.

In this aspect, when the data creation unit assumes the all-pin arrangement, when creating the recommended arrangement data of one board, one reference arrangement data is used as the arrangement position of the push-up pins supporting one board. Select the required position in. This allows one board to be properly supported by push-up pins located at the required positions. In addition, when creating the recommended placement data for one board, the data creation unit sets the selectable position in the reference placement data as a temporary placement position for push-up pins that support other boards other than one board. Select. That is, when supporting one board, the push-up pins for the other boards are not temporarily placed in the prohibited positions, but are temporarily placed in the selectable positions. This allows push-up pins for another board to be tentatively placed on the push-up plate while maintaining proper support for one board.

In the above data creation device, the data creation unit is arranged above the push-up plate when creating the recommended arrangement data of the one substrate in the case where the all pin arrangement is assumed. Considering the existence of a pair of conveyor rails for transporting the substrate, the push is used as a temporary arrangement position of the push-up pin supporting the other substrate in the selectable position in the reference arrangement data. The one located in the inner region of the pair of conveyor rails on the up plate is selected.

In this aspect, the data creation unit is in a position that can be selected as a temporary placement position of push-up pins for another board when creating recommended placement data for one board in the case of assuming all pin placement. Select the one located in the inner area of the pair of conveyor rails. As a result, when moving the push-up pins when changing the arrangement of the push-up pins according to the switching of the product type from one board to another board, it is necessary to move the push-up pins while avoiding interference with the pair of conveyor rails. There is no. Therefore, the efficiency of changing the arrangement of the push-up pins can be improved.

In the above data creation device, the data creation unit is configured to sequentially create the recommended arrangement data for each type of the substrate according to the switching order of the types of the substrate. Then, when the data creation unit changes the switching order, the value of the influential factor tends to improve the efficiency of changing the arrangement of the push-up pins according to the switching of the product type of the substrate. Changes the creation order of the recommended placement data according to the change of the switching order.

Then, when the average value of the processing machine preparation time for each type of the substrate is longer than the average value of the mounting machine preparation time, the data creating unit arranges the pins required for changing the arrangement of the push-up pins. The recommended placement data is created by setting the change time as the value of the influential factor and setting the recommended value of the pin placement change time to a value close to the processing machine preparation time.

Further, in the above data creation device, the data creation unit extracts the longest value in each mounting machine preparation time for each type of the board, and responds to the switching of the type of the board corresponding to the longest value. The recommended arrangement data is created by setting the recommended value of the pin arrangement change time at the time of changing the arrangement of the push-up pin to a value close to the processing machine preparation time.

In this aspect, when the average value of the processing machine preparation time for each type of substrate is longer than the average value of the mounting machine preparation time, the data creation unit sets the recommended value of the pin arrangement change time as the processing machine preparation time. Create recommended placement data by setting close values. When the average value of the processing machine preparation time for each board type is longer than the average value of the mounting machine preparation time, the system preparation time of the entire component mounting system at the time of switching the board type is determined by the processing machine preparation time. That is, even if the pin arrangement change time included in the mounting machine preparation time is set to an extremely short time, it does not contribute to the efficiency of the preparation processing of the entire component mounting system. In other words, it is sufficient that the pin arrangement change time is set to a value close to the processing machine preparation time. Such setting of the pin arrangement change time does not reduce the efficiency of the preparation process of the entire component mounting system.

As described above, according to the present invention, it is possible to provide a data creation device capable of efficiently changing the arrangement of push-up pins when switching board types, and a component mounting system equipped with the data creation device.
