1-5. Configuration Example of Production Control Device 70 As shown in FIG. 4 , the production control device 70 of this embodiment is provided in the line control computer 60 . The production management device 70 can also be formed on a management device that manages a plurality of substrate production facilities 1, a cloud, or the like. In addition, the production management device 70 includes an extractor 71 , a setter 72 , and a regulator 73 as control blocks. Further, the production management device 70 executes control according to the flowchart shown in FIG. 5, for example. The extraction unit 71 performs the process shown in step S11. The setting unit 72 performs the process shown in step S12. The regulation unit 73 performs the processing and determination shown in steps S13 to S18.

1-5-1. Extractor 71
The extraction unit 71 extracts the unit production UP0 having the same or similar related information RI0 based on the related information RI0 related to each unit production UP0 of the production plan PP0 (step S11 shown in FIG. 5). In this specification, the unit production UP0 extracted by the extraction unit 71 is called target production TP0, and the unit production UP0 that is not extracted by the extraction unit 71 is called non-target production NTP0.

FIG. 6 schematically shows an example of the relationship among production plan PP0, unit production UP0, related information RI0, target production TP0 and non-target production NTP0. As shown in the figure, the production plan PP0 defines the order of unit production UP0 in which the production of a predetermined board product PB0 using the board-oriented work machine WM is designated. The figure shows that a predetermined board product PB0 is produced using the work machine for board WM in the order of unit production UP1, unit production UP2 and unit production UP3.

Further, for each of the plurality of unit productions UP0, for example, the type and planned production quantity of the board product PB0 and the type and required quantity of the articles AR0 used in the production of the board product PB0 are defined. The figure shows that three kinds of board products PB0, for example, board product PB1, board product PB2, and board product PB3, are produced. The figure also shows that, for example, the planned production quantity N1 of the board product PB1 is produced, the planned production quantity N2 of the board product PB2 is produced, and the planned production quantity N3 of the board product PB3 is produced. Note that the items defined in the unit production UP0 described above are only an example, and each of the plurality of unit productions UP0 includes the period of use, place of use, number of items used, control program to be used, and the number of workers involved. Various information such as the required competence (work level) can be defined.

The related information RI0 is not limited as long as it is information related to each unit production UP0 of the production plan PP0. For example, for a predetermined unit production UP0 of the production plan PP0, there is a case where it is desired to set a permission condition for permitting the production of the printed circuit board product PB0 and control whether or not to permit the unit production UP0. Specifically, there is a case where it is desired to designate the article AR0, the board-to-board work machine WM, the worker, etc. used in the production for each client who requested the production of the board product PB0. In addition, there are cases where it is desired to designate the article AR0, the board-to-board work machine WM, the worker, etc. used in the production for each production lot of the board product PB0.

Furthermore, the board product PB0 used for vehicle equipment, medical equipment, etc. may require higher quality than the board product PB0 used for general electronic equipment. In this case, it may be desired to designate the article AR0, the board-oriented work machine WM, the worker, etc. used in the production for each required quality of the board product PB0. What has been described above regarding the required quality of the substrate product PB0 can be similarly applied to the use of the substrate product PB0.

Therefore, the related information RI0 is preferably information about at least one of the client who requested the production of the board product PB0, the production lot of the board product PB0, the required quality of the board product PB0, and the use of the board product PB0. In FIG. 6, for example, a client CL1 who requested the production of the board product PB1 (unit production UP1), a client CL2 who requested the production of the board product PB2 (unit production UP2), and a client CL2 who requested the production of the board product PB3 (unit production UP3). is indicated by the requester CL1 who requested the .

In the same figure, a production lot RT1 for the board product PB1, a production lot RT2 for the board product PB2, and a production lot RT3 for the board product PB3 are shown. Further, in the figure, the required quality QT1 of the board product PB1, the required quality QT2 of the board product PB2, and the required quality QT1 of the board product PB3 are shown. In addition, in the figure, the usage US1 of the substrate product PB1, the usage US2 of the substrate product PB2, and the usage US3 of the substrate product PB3 are shown. In the figure, related information RI1 of unit production UP1, related information RI2 of unit production UP2, and related information RI3 of unit production UP3 are shown.

The extraction unit 71 extracts the unit production UP0 having the same or similar related information RI0 based on the related information RI0. In the example shown in FIG. 6, the client who requested the production of the board product PB1 (unit production UP1) and the client who requested the production of the board product PB3 (unit production UP3) are the same client CL1. Therefore, the extracting unit 71 extracts the unit production UP1 and the unit production UP3 having the same client as the related information RI0. The above can be similarly applied to the required quality QT1 of the substrate product PB1 and the substrate product PB3.

It is assumed that the client who requested the production of the board product PB1 (unit production UP1) is different from the client who requested the production of the board product PB3 (unit production UP3). It is assumed that the client has a strong relationship with other clients, such as In this case, the client can be said to be a similar client. Therefore, in this case, the extraction unit 71 can extract the unit production UP1 and the unit production UP3 having similar clients, which are the related information RI0.

Similarly, the extraction unit 71 can determine that the related information RI0 is more similar for unit productions UP0 in which the production lots of the substrate products PB0 are closer, and extract the unit productions UP0. Further, the extraction unit 71 can determine that the related information RI0 is more similar to the unit production UP0 in which the required quality of the board product PB0 is closer, and extract the unit production UP0. Furthermore, the extracting unit 71 can determine that the related information RI0 is more similar to the unit production UP0 in which the board product PB0 has a similar purpose, and extract the unit production UP0.

As shown in FIG. 6, the unit production UP1 and the unit production UP3 extracted by the extraction unit 71 are the target production TP0. The unit production UP2 that is not extracted by the extraction unit 71 is the non-objective production NTP0. In this way, the extraction unit 71 can extract a plurality of unit productions UP0 based on one piece of related information RI0. The extraction unit 71 can also extract a plurality of unit productions UP0 based on a plurality of pieces of related information RI0.

Specifically, a unit production UP0 with the same or similar predetermined related information RI0 may differ from a unit production UP0 with the same or similar other related information RI0. In this case, the extraction unit 71 can extract multiple types of unit production UP0 (multiple groups of unit production UP0). The extraction unit 71 can also give priority to the related information RI0. Priority can be set arbitrarily. For example, when giving priority to the client who requested the production of the board product PB0 compared to the production lot, required quality, and usage of the board product PB0, the extraction unit 71 sets the priority of the client higher than that of other related information RI0. set. In this case, the extraction unit 71 extracts the unit production UP0 with the same or similar client.

1-5-2. Setting section 72 and regulation section 73
The setting unit 72 sets permission conditions for permitting production of the board product PB0 for the target production TP0, which is the unit production UP0 extracted by the extraction unit 71 (step S12 shown in FIG. 5). The permission condition is not limited as long as it permits the production of the printed circuit board product PB0. For example, the permission condition includes that the article AR0 to be used in the target production TP0 is a designated article that is designated to be used in the target production TP0. Designated goods can be designated arbitrarily. For example, designated items can be designated based on price, availability, and the like.

In this case, the setting unit 72 causes the storage device 6DS to store the designated article identification information that identifies the designated article. For example, when the client who requested the production of the printed circuit board product PB0 supplies the specified item, the registration of the specified item identification information can be performed, for example, when the item AR0 arrives. Specifically, the article AR0 is provided with an identification code. The identification code includes article identification information that identifies the article AR0. A one-dimensional code, a two-dimensional code, a wireless tag, or the like can be used as the identification code, for example. When the article AR0 arrives, the worker issues an identification code including article identification information using, for example, an article management device.

Also, the worker uses a barcode reader or the like to read the barcode or the like provided on the article AR0 by the supplier (vendor). Then, the worker can acquire the item information of the item AR0 from the storage device 6DS in which the item information about the item AR0 is registered. For example, when the article AR0 is a reel, information on the shape of the part accommodated in the reel, information on image processing of image data obtained by imaging the part, information on handling of the part, information on imaging conditions when imaging the part, Shape-related information, such as information about the electrical properties of the part, is included in the item information. Also, package information, which is information regarding the supply method of parts, is included in the article information.

The worker can also include at least part of the article information in the identification code, for example, using the management device. The worker attaches an identification code including at least the article identification information among the article identification information and the article information to the article AR0. The article AR0 to which the identification code is attached is transported and stored in the storage device 50 by an operator, an automatic guided vehicle (AGV), or the like.

The setting unit 72 acquires the target production TP0 from the extracting unit 71, and acquires the specified goods that are specified to be used in the target production TP0 from the production plan PP0 of the board product PB0. If the received article AR0 is a designated article, the setting unit 72 stores the article identification information included in the identification code in the storage device 6DS as designated article identification information for identifying the designated article. Further, the setting unit 72 can add management information indicating that the designated article is the designated article to the article information regarding the designated article, and store the information in the storage device 6DS. As the management information, for example, flag information indicating whether or not the item is a designated item can be used.

Note that the storage device 6DS of this embodiment is provided in the line control computer 60, as shown in FIG. The storage device 6DS can also be provided in a management device that manages a plurality of board production facilities 1, on a cloud, or the like. For the storage device 6DS, for example, a magnetic storage device such as a hard disk device, a storage device using a semiconductor device such as a flash memory, or the like can be used. In addition, the storage device 6DS can store various types of information, such as the above-mentioned product information and the production plan PP0 of the board product PB0. The article information and the production plan PP0 of the printed circuit board product PB0 may be created and managed by another arithmetic device or control device. In this case, the production control device 70 acquires the article information and the production plan PP0 of the printed circuit board product PB0 from the arithmetic device or the like.

The regulation unit 73 permits the target production TP0 when the permission conditions are satisfied, and prohibits the target production TP0 when the permission conditions are not satisfied (steps S13 to S18 shown in FIG. 5). For example, the regulation unit 73 satisfies the permission condition based on the difference between the article identification information identifying the article AR0 acquired in the preparation work for the target production TP0 and the specified article identification information stored in the storage device 6DS. decide whether to

Specifically, when the worker installs the article AR0 in the preparation work for the target production TP0, the worker reads the identification code attached to the article AR0 using a reading device, and installs the article AR0 at a predetermined position. Thereby, the line control computer 60 can recognize the article identification information of the mounted article AR0 and the place where the article AR0 is mounted.

The regulation unit 73 acquires the article identification information from the reading device and acquires the specified article identification information from the storage device 6DS (step S14). The regulation unit 73 determines whether or not the item identification information acquired in the preparation work for the target production TP0 matches the designated item identification information stored in the storage device 6DS (step S15). If the article identification information and the designated article identification information match (Yes in step S15), the regulation unit 73 determines that the permission conditions are satisfied and permits the target production TP0 (step S16). If the product identification information and the designated product identification information do not match (No in step S15), the regulation unit 73 determines that the permission conditions are not satisfied and prohibits the target production TP0 (step S17).

When a plurality of types of target production TP0 are extracted by the extraction unit 71, the setting unit 72 associates the target production identification information that specifies the target production TP0 with the designated product identification information that specifies the designated product, and stores them in the storage device. It's better to store it in the 6DS. The target production identification information can use an identification code and can be obtained from the extraction unit 71 in the same way as the designated product identification information. In this case, the regulation unit 73 combines the production identification information identifying the target production TP0 acquired in the preparation work for the target production TP0 and the article identification information identifying the article AR0 with the target production stored in the storage device 6DS. Whether or not the permission conditions are satisfied is determined based on the difference between the combination of the identification information and the designated article identification information.

Specifically, an identification code including production identification information is assigned to a work instruction sheet used by a worker. When the worker equips the article AR0 in the preparatory work for the target production TP0, first, the regulation unit 73 can acquire the production identification information by reading the identification code of the work instruction sheet using a reading device. can. Also, the worker uses a reading device to read the identification code attached to the article AR0 to be used in the target production TP0, and mounts the article AR0 at a predetermined position.

The regulation unit 73 acquires the production identification information and the article identification information from the reading device, and acquires the target production identification information and the designated article identification information from the storage device 6DS (modification of the processing shown in step S14). The regulation unit 73 determines whether the combination of the production identification information and the article identification information acquired in the preparation work for the target production TP0 matches the combination of the target production identification information and the designated article identification information stored in the storage device 6DS. It is determined whether or not (modification of the process shown in step S15).

If the above combinations match (Yes in the modified form of the process shown in step S15), the regulation unit 73 determines that the permission condition is satisfied and permits the target production TP0 (step S16). If the above combinations do not match (No in the modified form of the process shown in step S15), the regulation unit 73 determines that the permission conditions are not satisfied and prohibits the target production TP0 (step S17).

It should be noted that if the above processing and determination are performed for all the articles AR0 that are scheduled to be used in the target production TP0, the processing and determination may become complicated. Therefore, when the management information is added to the article information of the article AR0 acquired in the preparation work for the target production TP0, the regulation section 73 may determine whether or not the permission conditions are satisfied (step S13). Specifically, when the management information is added to the article information (Yes in step S13), the regulating section 73 performs the processing and judgment shown in steps S14 to S17. When the management information is not added to the article information (No in step S13), the regulating section 73 does not perform the processing and determination in steps S14 to S17, but makes the determination in step S18. What has been said above can be similarly applied to the above variations.

The regulation unit 73 determines whether or not the permission conditions have been determined for all the articles AR0 scheduled to be used in the target production TP0 having management information added to the article information (step S18). If all the articles AR0 have been determined (Yes in step S18), the control is once terminated. If all articles AR0 have not been judged (No in step S18), the control returns to the judgment shown in step S13, and the processing and judgment shown in steps S13 to S17 are continued until all articles AR0 have been judged. is repeated.

Further, for example, the permission condition includes that the board-to-board work machine WM scheduled to be used in the target production TP0 is a certified work machine that is certified to be used in the target production TP0. In this case, the production control device 70 executes control according to the flowchart shown in FIG. 7, for example. The extraction unit 71 performs the process shown in step S21. The setting unit 72 performs the process shown in step S22. The regulation unit 73 performs the processing and judgment shown in steps S23 to S26. Note that the process shown in step S21 is the same as the process shown in step S11, and redundant description is omitted in this specification.

In this form, the setting unit 72 causes the storage device 6DS to store authentication work machine identification information for specifying the authentication work machine (step S22). The certified work machine is certified in advance by, for example, a client who requested production of the board product PB0. As the authentication work machine identification information, for example, the identification information of the authentication work machine (for example, a serial number) can be used. The regulation unit 73 satisfies the permission condition based on the difference between the work machine identification information for identifying the board-oriented work machine WM to be used in the target production TP0 and the authentication work machine identification information stored in the storage device 6DS. decide whether to

As described above, each device constituting the board production facility 1 is configured to be able to input/output various data to/from the line control computer 60 via the network. The regulation unit 73 acquires the work machine identification information from the board-oriented work machine WM scheduled to be used in the target production TP0, and acquires the authenticated work machine identification information from the storage device 6DS (step S23). The regulation unit 73 determines whether or not the work machine identification information of the board-oriented work machine WM scheduled to be used in the target production TP0 matches the authenticated work machine identification information stored in the storage device 6DS (step S24). ).

If the work machine identification information and the authenticated work machine identification information match (Yes in step S24), the regulation unit 73 determines that the permission conditions are satisfied, and permits the target production TP0 (step S25). If the work machine identification information and the authenticated work machine identification information do not match (No in step S24), the regulation unit 73 determines that the permission conditions are not satisfied, and prohibits the target production TP0 (step S26).

Further, for example, the permission conditions include that the worker scheduled to work on the target production TP0 is a certified worker who is certified to work on the target production TP0. In this case, the production management device 70 executes control according to the flowchart shown in FIG. 8, for example. The extraction unit 71 performs the process shown in step S31. The setting unit 72 performs the process shown in step S32. The regulation unit 73 performs the processing and judgment shown in steps S33 to S36. Note that the process shown in step S31 is the same as the process shown in step S11, and redundant description is omitted in this specification.

In this form, the setting unit 72 causes the storage device 6DS to store the authentication operator identification information that specifies the authentication operator (step S32). A certified worker is, for example, a worker who has a predetermined work level, and is pre-certified by completion of predetermined training, acquisition of qualifications, and the like. For example, the identification information of the authentication operator (e.g., employee number, registration number, etc.) can be used as the authentication operator identification information. The regulation unit 73 determines whether or not the permission conditions are satisfied based on the difference between the worker identification information for identifying the worker scheduled to engage in the target production TP0 and the authenticated worker identification information stored in the storage device 6DS. to judge whether

For example, a worker carries a worker identification card with an identification code for identifying the worker. The worker reads the identification code of the worker identification card using a reader before engaging in the target production TP0. The regulation unit 73 acquires the worker identification information included in the identification code from the reading device, and acquires the authenticated worker identification information from the storage device 6DS (step S33). The regulation unit 73 determines whether or not the worker identification information for identifying the worker scheduled to engage in the target production TP0 matches the authenticated worker identification information stored in the storage device 6DS (step S34). .

If the worker identification information and the authenticated worker identification information match (Yes in step S34), the regulation unit 73 determines that the permission conditions are satisfied and permits the target production TP0 (step S35). If the worker identification information and the authenticated worker identification information do not match (No in step S34), the regulation unit 73 determines that the permission conditions are not satisfied and prohibits the target production TP0 (step S36).

Further, for example, in the non-target production NTP0 that is the unit production UP0 that is not extracted by the extraction unit 71, if the article AR0 that is scheduled to be used only in the target production TP0 is used, the board production equipment 1 will There is a possibility that the article AR0 cannot be used. Furthermore, if the non-target production NTP0 uses the board-oriented work machine WM that is to be used only in the target production TP0, it is not preferable in terms of management of the board-oriented work machine WM.

Therefore, the setting unit 72 sets a prohibition condition for prohibiting the use of the article AR0 and the board-to-board work machine WM that are scheduled to be used only in the target production TP0 for the non-target production NTP0, which is the unit production UP0 that is not extracted by the extraction unit 71. Good to set. In this case, the production management device 70 executes control according to the flowchart shown in FIG. 9, for example. The setting unit 72 performs the process shown in step S41. The regulation unit 73 performs the processing and judgment shown in steps S42 to S44. The non-target production NTP0 is the unit production UP0 that was not extracted by the extraction unit 71, and the extraction unit 71 extracts the target production TP0 to specify the non-target production NTP0.

In this form, the setting unit 72 causes the storage device 6DS to store the designated article identification information that identifies the designated article described above. Further, the setting unit 72 causes the storage device 6DS to store authentication work machine identification information for specifying the authentication work machine described above (step S41). Similarly to the case of permitting or prohibiting the target production TP0, the regulation unit 73 prohibits the non-target production NTP0 when the prohibition conditions are satisfied, and permits the non-target production NTP0 when the prohibition conditions are not satisfied. That is, the regulation unit 73 determines whether or not the prohibition condition is satisfied (step S42). If the prohibition condition is satisfied (Yes in step S42), the regulation unit 73 prohibits non-target production NTP0 (step S43). If the prohibition condition is not satisfied (No in step S42), non-target production NTP0 is permitted (step S44).

Specifically, the regulation unit 73 acquires the article identification information from the reading device and acquires the specified article identification information from the storage device 6DS. The regulation unit 73 determines whether or not the article identification information acquired in the preparatory work for the non-targeted production NTP0 matches the specified article identification information stored in the storage device 6DS. When the article identification information and the designated article identification information match, the regulation unit 73 determines that the prohibition condition is satisfied, and prohibits the non-target production NTP0. If the product identification information and the designated product identification information do not match, the regulation unit 73 determines that the prohibition condition is not satisfied, and permits non-target production NTP0.

Similarly, the regulation unit 73 acquires the work machine identification information from the board-oriented work machine WM, and acquires the authentication work machine identification information from the storage device 6DS. The regulation unit 73 determines whether or not the work machine identification information of the board-oriented work machine WM scheduled to be used in the non-target production NTP0 matches the authenticated work machine identification information stored in the storage device 6DS. When the work machine identification information and the authenticated work machine identification information match, the regulation unit 73 determines that the prohibition condition is satisfied, and prohibits the non-target production NTP0. If the work machine identification information and the authenticated work machine identification information do not match, the regulation unit 73 determines that the prohibition condition is not satisfied, and permits non-target production NTP0.

The board production facility 1 of this embodiment includes a board-oriented work machine WM and an article moving device 40 that supplies the board-oriented work machine WM with an article AR0 used in the production of the board product PB0. Further, the board-to-board work machine WM has a first slot 121 that exchangeably holds an article AR0 used in the production of the board product PB0, and an article AR0 that can hold the article AR0 in advance or temporarily hold the article AR0 that is to be collected. and a second slot 122 capable of holding. Furthermore, the article moving device 40 exchanges the article AR0 between the first slot 121 and the second slot 122. FIG.

In the substrate production facility 1 described above, the second slot 122 holds both the replenishment article AR0 used in the current production and the setup change article AR0 used in the subsequent production. can be done. For example, assume that the current production is the target production TP0 and the subsequent production is the non-target production NTP0. In this case, in the board production facility 1 that does not have the production management device 70, there is a possibility that the replenishment article AR0 will be used in the non-objective production NTP0. Also, there is a possibility that the item AR0 for setup change will be used in the target production TP0. Since the board production facility 1 of the present embodiment includes the production management device 70, it is possible to separately supply the replenishment article AR0 and the setup change article AR0.

Note that the production control device 70 can also be applied to the board production facility 1 that does not have the article moving device 40 . In this case, for example, the worker equips a predetermined slot with the replenishment article AR0. When the current production (target production TP0) is completed, the worker collects the article AR0 used in the current production and puts the setup change article AR0 to be used in the next production (non-target production NTP0) into a predetermined slot. to equip. At this time, the replenishment article AR0 and the setup change article AR0 may coexist. Equipped with the production management device 70, the board production facility 1 can distinguish between the supply goods AR0 and the setup change goods AR0.
