MODE FOR CARRYING OUT THE DISCLOSURE

[0009] Prior to describing the embodiments of the present disclosure, problems with conventional devices will be briefly described. In the conventional technology, in addition to the production work of machining workpieces in production equipment on the production floor, preparatory work that is performed in conjunction with the production work is also performed in parallel. However, although the progress of the preparatory work also affects the production of products, the production progress of the entire production floor is not managed taking these into consideration, and there is room for further improvement. Therefore, the present disclosure aims to provide a production management device, a production management method, and a data structure that can easily grasp the progress status of the entire production floor.

[0010] An embodiment of the present disclosure will be described in detail below with reference to the drawings. The configurations, shapes, etc. described below are examples for the purpose of explanation, and can be appropriately changed according to the specifications of the component mounting system, component mounting line, component mounting device, etc. In the following, the same reference numerals are used for corresponding elements in all drawings, and duplicated explanations will be omitted.

[0011] Fig. 1 is a configuration explanatory diagram of a component mounting system 1 according to an embodiment of the present disclosure. First, the configuration of the component mounting system 1 will be described with reference to Fig. 1. The component mounting system 1 is configured to connect three component mounting lines L1 to L3 arranged on a production floor F via a communication network 2 and manage them using a production management device 3.

[0012] The component mounting lines L1-L3 are arranged in a production area Ap provided on the production floor F. As described below, each of the component mounting lines L1-L3 is configured by connecting a plurality of production facilities including a screen printing device and a component mounting device, and has a function of producing a mounted board (product) in which components are mounted on a board (workpiece) under the control of each of the line management devices B1-B3. Note that the number of component mounting lines L1-L3 provided in the component mounting system 1 does not need to be three, and may be one, two, four or more. Furthermore, the line management devices B1-B3 do not need to be provided in correspondence with the component mounting lines L1-L3, and may be more or less than the number of the component mounting lines.

[0013] In FIG. 1, a placement work support device 4 is placed in a preparation area As, which is different from the production area Ap provided on the production floor F. The placement work support device 4 is connected to a production management device 3 and the like via a communication network 2. A replacement cart 5, which is the subject of placement work described below, is connected to the placement work support device 4. Note that the connection here includes a physical connection as well as a virtual connection via wireless communication. A plurality of carts 5 in various states, such as before, during, or after placement work, are stored in the preparation area As. Also, the preparation area As stores a plurality of removable elements, such as screen masks, tape feeders, mounting heads, suction nozzles, parts, and solder, which are shared by the production equipment arranged on the production floor F.

[0014] The trolleys 5 connected to the placement work support device 4 are subjected to placement work (preparation work) according to instructions corresponding to the board type of mounted boards to be produced in the component mounting lines L1 to L3. As placement work, the worker W performs work such as removing from the trolleys 5 a plurality of tape feeders that supply the specified components, and the components, and attaching them to the specified positions on the trolleys 5. The trolleys 5 in the preparation area As, which include the trolleys 5 connected to the placement work support device 4, can perform placement work in parallel with the production of mounted boards in the component mounting lines L1 to L3. Hereinafter, the preparation work for a type change outside the component mounting lines L1 to L3, including the placement work on the trolleys 5, is referred to as off-site setup work.

[0015] When changing the type of mounted boards produced in the component mounting lines L1 to L3, the worker W moves the cart 5 that has completed placement work in the preparation area As to the component mounting line L1 to L3, and performs a product type changeover work of exchanging it with the cart 5 attached to the component mounting device. In addition, in the product type changeover work, the worker W moves replacement screen masks, tape feeders, mounting heads, suction nozzles, components, solder, etc. stored in the preparation area As to the component mounting line L1 to L3 and replaces them. Hereinafter, the preparation work for product type change in the component mounting lines L1 to L3 is referred to as internal setup work. In addition, in the product type changeover work, transportation and switching may be performed using a transport vehicle V described later.

[0016] In Fig. 1, a worker W has a work terminal T to be used in preparation work. The work terminal T is equipped with a terminal communication unit Ta that wirelessly communicates to send and receive various information, and a touch panel Tb with a display function and an input function. The work terminal T displays the received various information on the touch panel Tb and transmits various information input from the touch panel Tb. Note that as long as the work terminal T has a display function and an input function, it does not have to be the touch panel Tb, and may be, for example, a terminal device with a display function such as a glasses-type wearable device or an input function using voice or gestures.

[0017] On the production floor F, transport vehicles V are deployed to move replacement screen masks, tape feeders, mounting heads, suction nozzles, components, solder, carts 5, and the like stored in the preparation area As to the component mounting lines L1 to L3. The transport vehicles V are equipped with a transport vehicle communication unit Va that wirelessly communicates to send and receive various information. The transport vehicles V autonomously move between predetermined positions on the production floor F based on the received instructions and information they collect using beacons (not shown) installed on the production floor F, various sensors (GPS, obstacle sensors, etc. (not shown) built into the transport vehicles V, cameras, etc.

[0018] In FIG. 1, the component mounting system 1 includes a production planning device 6 and a preparation work management device 7 connected to a communication network 2. The production planning device 6 plans (creates) an optimal production plan and preparation plan by simulation based on various information. The preparation work management device 7 issues preparation instructions regarding the preparation work to the placement work support device 4, the work terminal T used by the worker W, and preparation work bodies such as the transport vehicle V, based on the preparation plan. The preparation work management device 7 includes a preparation wireless communication unit 7a that wirelessly communicates with the terminal communication unit Ta of the work terminal T and the transport vehicle communication unit Va of the transport vehicle V. The preparation work management device 7 transmits work instructions to the work terminal T and the transport vehicle V and receives preparation results via the preparation wireless communication unit 7a.

[0019] Next, the detailed configuration of the component mounting lines L1 to L3 will be described with reference to Fig. 2. Fig. 2 is a configuration explanatory diagram of each of the component mounting lines L1 to L3 equipped in the component mounting system 1. The component mounting lines L1 to L3 have the same configuration, and the component mounting line L1 will be described below. In the component mounting line L1, production equipment such as a board supply device M1, a screen printing device M2, component mounting devices M3 to M6, a reflow device M7, and a board recovery device M8 are connected in series from the upstream side (left side of the paper) to the downstream side (right side of the paper) in the board transport direction. Each production equipment is mutually connected to a line management device B1 and other production equipment via an in-line communication network 8.

[0020] That is, the production equipment (production work unit) of the component mounting line L1 (L2, L3) is connected to the line management device B1 (B2, B3) via the intra-line communication network 8, and is also connected to other production equipment of the same component mounting line L1 to L3 via the intra-line communication network 8. The component mounting line L1 (L2, L3) may be equipped with a storage shelf for storing screen masks, tape feeders, mounting heads, suction nozzles, components, solder, etc., which are used in the next production run (not shown) or which are transported to the preparation area As after production. The storage shelf may be connected to the component mounting line L1 (L2, L3) or may be installed as a stand-alone unit.

[0021] The line management device B1 transmits production instructions to instruct production work to the production equipment of the component mounting line L1 via the intra-line communication network 8 based on the production plan received via the communication network 2. The line management device B1 also collects production results from the production equipment and transmits them to the production management device 3 and the like via the communication network 2. Note that the component mounting line L1 is composed of a group of production equipment connected via the intra-line communication network 8, and the production equipment does not need to be physically connected to each other.

[0022] In Fig. 2, board supplying device M1 has a storage section such as a rack that stores multiple boards (workpieces), and performs a board supplying operation of supplying boards taken out of the storage section to a downstream device. Screen printing device M2 performs a solder printing operation of printing solder on boards brought in from the upstream side through a screen mask attached to the printing operation section. Note that component mounting line L1 may be provided with a solder application device that applies solder to boards using a dispenser, either in parallel with screen printing device M2 or instead of screen printing device M2. Screen printing device M2 and solder application device are printing devices that deposit solder on boards.

[0023] The component mounting devices M3 to M6 perform a component mounting operation in which components are mounted by a mounting head on a board on which solder has been deposited. The component mounting line L1 is not limited to a configuration in which the component mounting devices M3 to M6 are four, and may have one to three or five or more component mounting devices M3 to M6. The reflow device M7 performs a board heating operation in which the board carried into the device is heated by a board heating unit to melt the solder on the board, and the solder is hardened to bond the electrode part of the board to the component. The board recovery device M8 has a storage unit such as a rack for storing multiple boards, and performs a board recovery operation in which the board carried out by an upstream device is received and recovered in the storage unit.

[0024] Next, with reference to Fig. 3 and Fig. 4, a configuration relating to progress management for managing the production progress of mounted boards (products), among the functions of component mounting system 1, will be described. Fig. 3 is a block diagram showing the configuration of component mounting system 1 (progress management system). Fig. 4 shows an example of a data structure used for management processing of production progress by component mounting system 1 (progress management system). In Fig. 3, a production management device 3, a production planning device 6, line management devices B1-B3, and a preparation work management device 7 provided in component mounting system 1 transmit and receive various information and instructions to each other via a communication network 2.

[0025] The production management device 3 includes an information acquisition unit 10, a number issuing unit 11, a progress management unit 12, an information transmission unit 13, an instruction change unit 14, and a management storage unit 15. The management storage unit 15 is a storage device, and stores production order information 15a, production instruction information 15b, preparation instruction information 15c, production result information 15d, preparation result information 15e, production plan information 15f, preparation plan information 15g, corrected production plan information 15h, corrected preparation plan information 15i, and the like.

[0026] The production planning device 6 includes a plan communication unit 20, a plan planning unit 21, a revised plan planning unit 22, and a plan storage unit 23. The plan storage unit 23 is a storage device, and stores order information 23a, product information 23b, line configuration information 23c, material information 23d, cart information 23e, worker information 23f, a production plan 23g, a preparation plan 23h, a production result 23i, a preparation result 23j, a revised production plan 23k, a revised preparation plan 23m, and the like.

[0027] 3, each of the line management devices B1 to B3 includes an outside-line communication unit 30, an inside-line communication unit 31, a production instruction unit 32, a production result collection unit 33, and a line memory unit 34. The line memory unit 34 is a memory device and stores product information 34a, a production plan 34b, production instructions 34c, production results 34d, etc. The preparation work management device 7 includes a preparation communication unit 40, a preparation wireless communication unit 7a, a preparation instruction unit 41, a preparation result collection unit 42, and a preparation memory unit 43. The preparation memory unit 43 is a memory device and stores product information 43a, a preparation plan 43b, preparation instructions 43c, preparation results 43d, etc.

[0028] The information acquisition unit 10 of the production management device 3 acquires information from other devices via the communication network 2 and stores it in the management storage unit 15. The information transmission unit 13 of the production management device 3 transmits the information stored in the management storage unit 15 to the other devices via the communication network 2. The plan communication unit 20 of the production planning device 6 acquires information from other devices via the communication network 2 and stores it in the plan storage unit 23, and transmits the information stored in the plan storage unit 23 to the other devices via the communication network 2.

[0029] 3, the off-line communication unit 30 of each of the line management devices B1 to B3 acquires information from other devices via the communication network 2, stores it in the line memory unit 34, and transmits the information stored in the line memory unit 34 to the other devices via the communication network 2. The in-line communication unit 31 of the line management devices B1 to B3 transmits and receives various information and instructions to and from the production equipment via the in-line communication network 8. The preparation communication unit 40 of the preparation work management device 7 transmits and receives various information and instructions to and from other devices and the placement work support device 4 via the communication network 2. The preparation wireless communication unit 7a of the preparation work management device 7 transmits and receives various information and instructions to and from the work terminal T and the transport vehicle V via wireless communication.

[0030] The information acquisition unit 10 of the production management device 3 acquires an order from an order management device (not shown). The order includes a board type name that specifies the mounted boards to be produced in the component mounting system 1, the number to be produced, a production lead time, and the like. Based on the acquired order, the number issuing unit 11 issues a unique order number for managing the order as a single unit of lot (see FIG. 4). The number issuing unit 11 also associates the order number with the order and stores it in the management storage unit 15 as production order information 15a. The order number is further associated with a board number that is assigned to each board within the lot. This allows the component mounting system 1 to manage the production progress for each board (work).

[0031] The order management device may have a management function other than order acceptance, and may be an ERP (Enterprise Resource Planning) that also manages purchasing, accounting, shipping, etc. In addition, when a plurality of order orders are treated as one unit lot in a production plan with production optimization, the number issuing unit 11 issues a unique order number for each order and associates the order number with the order order to create the production order information 15a. In addition, when one order order is divided into a plurality of unit lots for production, the number issuing unit 11 issues the same order number. Alternatively, the number issuing unit 11 may issue the same order number by adding a branch number, or may issue completely different order numbers and group the issued order numbers to manage them as order orders. An appropriate order number is selected as the issuing method depending on the type of work and the production system.

[0032] 3, the information transmission unit 13 of the production management device 3 transmits production order information 15a for making a production plan and a preparation plan to the production planning device 6. The plan communication unit 20 of the production planning device 6 stores the received production order information 15a as order information 23a in the plan storage unit 23. The plan communication unit 20 also acquires information such as the board size of the board type corresponding to the order information 23a, the type of components to be mounted, and the mounting position from a product information management device (not shown) and stores it in the plan storage unit 23 as product information 23b. The plan communication unit 20 also acquires information such as the type and arrangement of the production equipment constituting the component mounting line L1 (L2, L3) from the line management device B1 (B2, B3) and stores it in the plan storage unit 23 as line configuration information 23c.

[0033] The plan communication unit 20 also acquires inventory status of components, screen masks, suction nozzles, etc. used in the production of the board type corresponding to the order information 23a from a component management device (not shown), and stores the inventory status as component information 23d in the plan storage unit 23. The plan communication unit 20 also acquires information such as the state of the cart 5 (used in production on the component mounting line L1 (L2, L3), being placed in the preparation area As, stored in the preparation area As, etc.), tape feeders attached to the cart 5, and components (supplied component types) from the preparation work management device 7, and stores the information as cart information 23e in the plan storage unit 23. The plan communication unit 20 also acquires worker information 23f including information such as working hours and work skill level for each piece of information identifying a worker W working in the production area Ap and the preparation area As from a worker management device (not shown), and stores the information in the plan storage unit 23.

[0034] In FIG. 3, the planning unit 21 of the production planning device 6 executes a simulation based on order information 23a, product information 23b, line configuration information 23c, component information 23d, cart information 23e, and worker information 23f, and creates (draws) a production plan 23g that is optimal for producing mounted boards in the component mounting system 1 in a specified period, such as one day or one week, and a preparation plan 23h for preparation work in the preparation area As.

[0035] The production plan 23g includes information for identifying the component mounting lines L1 to L3 that produce the mounting boards, the production start date and time, the production end date and time, the number of pieces to be produced, information for identifying the preparation work (preparation work number), etc. In addition to simulation, methods such as machine learning and optimization may be used to plan (create) the optimal production plan 23g and preparation plan 23h, as long as they are optimal production plans that meet the delivery dates set in the order information 23a.

[0036] The preparation plan 23h includes information identifying the preparation work (preparation work number), the work start date and time, the work end date and time, the number of workers, etc. The created production plan 23g and preparation plan 23h are stored in the plan storage unit 23. The plan communication unit 20 transmits the created production plan 23g and preparation plan 23h to the production management device 3. The information acquisition unit 10 of the production management device 3 associates the received production plan 23g and preparation plan 23h with an order number based on the production order information 15a, and stores them in the management storage unit 15 as production plan information 15f and preparation plan information 15g.

[0037] The plan communication unit 20 also transmits the created production plan 23g to the line management device B1, B2, or B3 in charge. The off-line communication unit 30 of each of the line management devices B1 to B3 stores the received production plan 23g as a production plan 34b in the line storage unit 34. The plan communication unit 20 also transmits the created preparation plan 23h to the preparation work management device 7. The preparation communication unit 40 of the preparation work management device 7 stores the received preparation plan 23h in the preparation storage unit 43 as a preparation plan 43b.

[0038] Here, an example of the production plan 23g and preparation plan 23h created by the production planning device 6 displayed along the production time will be described with reference to FIG. 5. FIG. 5 is an explanatory diagram of an example of the production plan and preparation plan created by the component mounting system 1. In FIG. 5, the production plan 23g is displayed along the production time for each of the component mounting lines L1 to L3. That is, in the component mounting line L1, the production of the mounted boards of the lots X2, X5, and X8 is planned in this order. Similarly, in the component mounting line L2, the production of the lots X3, X6, and X9 is planned, and in the component mounting line L3, the production of the lots X1, X4, X7, and X10 is planned. The left side of the rectangle representing each of the lots X1 to X10 indicates the production start date and time, and the right side indicates the production end date and time.

[0039] In the production area Ap and the preparation area As, six groups of carts Z1 to Z6 are prepared, each group consisting of a plurality of carts 5 that are mounted together on the component mounting devices M3 to M6 of the component mounting lines L1 to L3 for use. In Fig. 5, as the preparation plan 23h, the arrangement work (external setup work) on the cart groups Z1 to Z6 for producing the lots X1 to X10 is displayed along with the production time for each of the preparation work numbers Y1 to Y10 that specify the arrangement work. The left side of the rectangle representing each of the preparation work numbers Y1 to Y10 indicates the work start date and time, the right side indicates the work end date and time, and the top side indicates the number of workers W. Here, preparation work with 1, 2, and 3 workers W is included.

[0040] 5, in the preparation area As, three workers W perform an external setup operation (preparation operation) of preparation operation number Y1 for producing mounted boards for lot X1 on a cart 5 of a cart group Z1. When the preparation operation is completed, the carts 5 mounted on the component mounting devices M3 to M6 of the component mounting line L3 are removed and the carts 5 of the cart group Z1 are attached. In the preparation area As, three workers W perform an external setup operation of preparation operation number Y2 for lot X2 on a cart 5 of a cart group Z2, two workers W perform an external setup operation of preparation operation number Y3 for lot X3 on a cart 5 of a cart group Z3, and one worker W performs an external setup operation of preparation operation number Y4 for lot X4 on a cart 5 of a cart group Z4.

[0041] 5, when the production of lot X1 is completed in component mounting line L3, the screen mask installed in screen printing device M2 is replaced, and the carriage 5 of carriage group Z1 attached to component mounting devices M3 to M6 is replaced with a carriage 5 of carriage group Z4. Depending on the content of the next production, the mounting head, suction nozzle, and solder may also be replaced.

[0042] The cart 5 of cart group Z1 removed from component mounting devices M3 to M6 is transported to preparation area As, where the external setup work of preparation work number Y7 for lot X7 is performed. In the external setup work of preparation work number Y7, first, one worker W removes multiple tape feeders and components from cart 5, and stores the removed tape feeders and components or attaches them to cart 5. Partway through the removal work, another worker W is added. When the removal work is completed, two workers W perform the work of attaching multiple tape feeders and components to designated positions on cart 5.

[0043] 5, among the replaced carts 5 of the cart group, those that are not scheduled for next use in the production plan 23g are transported to and stored in the preparation area As. For example, the cart 5 of the cart group Z2 that was used in the production of mounted boards of lot X2 on component mounting line L1 and the cart 5 of the cart group Z3 that was used in the production of mounted boards of lot X3 on component mounting line L2 are transported to and stored in the preparation area As after production is completed.

[0044] 3, the out-line communication unit 30 of each of the line management devices B1 to B3 acquires information required for production on the component mounting line L1, L2, or L3 that manages the board type specified in the production plan 34b from the product information management device, and stores the information as product information 34a in the line storage unit 34. The production instruction unit 32 of each of the line management devices B1 to B3 creates production instructions 34c that instruct production work such as component mounting work to production equipment (production work bodies) including component mounting devices M3 to M6 of the component mounting line L1, L2, or L3 that it manages, based on the product information 34a and production plan 34b. The created production instructions 34c are stored in the line storage unit 34, and are sent (instructed) to the corresponding production equipment by the in-line communication unit 31.

[0045] Further, the off-line communication unit 30 transmits the created production instruction 34c to the production management device 3. The number issuing unit 11 of the production management device 3 associates the received production instruction 34c with an order number based on the production order information 15a, and stores it as production instruction information 15b in the management storage unit 15 (see FIG. 4). That is, in the production instruction information 15b, information (order number) that identifies the work is linked to the production instruction 34c that instructs the production operator (production equipment including component mounting devices M3 to M6) to perform production work (component mounting work) to process the work (board).

[0046] As a method of linking the production instruction 34c with information (order number) for identifying the work, a unique number (which may be different from the order number as long as it is unique) for identifying the work may be added to the production instruction 34c, or a tree structure may be used in which the information for identifying the work (order number) is the parent node. Also, each of the line management devices B1 to B3 and the placement work support device 4 may convert the order number transmitted from the production management device 3, issue it as a new number, and manage it as a specific number within each of the line management devices B1 to B3 and the placement work support device 4, and when transmitting information to the production management device 3, convert the number again to use it as information for identifying the work.

[0047] 3, the production record collection unit 33 of each of the line management devices B1 to B3 collects production records 34d from production equipment (production work bodies) including component mounting devices M3 to M6 of the component mounting lines L1, L2, or L3 that it manages, and stores the production records 34d in the line storage unit 34. For example, the production records 34d are stored by associating the date and time when a board (work) is transported between production equipment with the board number assigned within the lots X1 to X10. The production records 34d are collected at regular intervals for each hour or for each board (work).

[0048] Furthermore, production performance 34d may include any of the following: information on the screen mask used to deposit solder on the substrate (work), information on the solder deposited on the substrate (work) and the date and time, the date and time the substrate (work) was brought in, the date and time the substrate (work) was removed, information on the components mounted on the substrate (work) and the date and time, information on the mounting head and nozzle that mounted the components on the substrate (work), information on the feeder that supplied the components to the substrate (work), information on any error that occurred and the date and time, and the date and time when mounting on the substrate (work) was stopped and the date and time when mounting was resumed.

[0049] The off-line communication unit 30 transmits the collected production record 34d to the production management device 3. The number issuing unit 11 of the production management device 3 associates the received production record 34d with an order number based on the production order information 15a, and stores it as production record information 15d in the management storage unit 15 (see FIG. 4). That is, in the production record information 15d, information (order number) that identifies the work is linked to production record 34d of the production operation body (production equipment including component mounting devices M3 to M6) for the work (board).

[0050] 3, a preparation communication unit 40 of the preparation work management device 7 acquires information required for preparation work (such as external setup work) for producing the board type instructed in the preparation plan 43b from the product information management device, and stores it as product information 43a in the preparation storage unit 43. A preparation instruction unit 41 of the preparation work management device 7 creates preparation instructions 43c for instructing preparation work to preparation work bodies such as a work terminal T carried by a worker W who performs the preparation work and a transport vehicle V that transports materials such as parts related to the production work (workpiece processing) based on the product information 43a and the preparation plan 43b. The created preparation instructions 43c are stored in the preparation storage unit 43, and are transmitted to the corresponding work terminal T and transport vehicle V by the preparation wireless communication unit 7a.

[0051] The preparation instruction 43c is transmitted to the placement work support device 4 (preparatory work body) by the preparation communication unit 40. The preparation communication unit 40 transmits the created preparation instruction 43c to the production management device 3. The number issuing unit 11 of the production management device 3 associates the received preparation instruction 43c with an order number based on the production order information 15a, and stores it as preparation instruction information 15c in the management storage unit 15 (see FIG. 4). That is, in the preparation instruction information 15c, information (order number) that identifies the work is linked to the preparation instruction 43c that instructs the preparation work body (work terminal T, transport vehicle V, placement work support device 4) to perform preparation work for processing the work (mounting components on a board).

[0052] As a method of linking the preparation instruction 43c with the information (order number) for identifying the workpiece, a unique number for identifying the workpiece may be added to the preparation instruction 43c, or a conversion table may be held to virtually link the workpiece. Note that the information for identifying the workpiece (order number) and the unique number for identifying the workpiece may not be the same, but may be different.

[0053] 3, the preparation record collection unit 42 of the preparation work management device 7 collects preparation records 43d from preparation work bodies such as the work terminal T, the transport vehicle V, and the placement work support device 4, and stores them in the preparation storage unit 43. For example, the preparation record 43d stores the work of removing a tape feeder or a part from a cart 5 as off-site setup work, storing the part, and attaching the part in association with a preparation instruction 43c, the date and time when the work was completed, and information identifying the tape feeder, cart 5, etc. that are the target of the work. The preparation record 43d may also include information about the worker W who performed the off-site setup work.

[0054] The preparation communication unit 40 transmits the collected preparation results 43d to the production management device 3. The information acquisition unit 10 of the production management device 3 associates the received preparation results 43d with an order number based on the production order information 15a, and stores the preparation results 43d as preparation result information 15e in the management storage unit 15 (see FIG. 4). That is, in the preparation result information 15e, information (order number) that identifies the work is linked to the preparation results 43d of the preparation operation bodies (operation terminal T, transport vehicle V, placement operation support device 4) for the workpiece (board).

[0055] In Fig. 3, the progress management unit 12 of the production management device 3 includes a progress difference calculation unit 12a as an internal processing unit. The progress difference calculation unit 12a calculates the progress difference between the production plan 23g and the production result 34d based on the production plan information 15f and the production result information 15d. For example, the progress difference calculation unit 12a calculates the progress difference between the planned and actual date and time when the board is collected by the board collection device M8 of each of the component mounting lines L1 to L3 for each board (work) identified by the order number and the board number. Similarly, the progress difference calculation unit 12a calculates the progress difference between the preparation plan 23h and the preparation result 43d based on the preparation plan information 15g and the preparation result information 15e.

[0056] The progress management unit 12 manages the production progress of the board (workpiece) based on the calculated progress difference. For example, the progress management unit 12 determines that the progress is smooth when the progress difference between the production plan 23g and the production result 34d is within a predetermined difference, or when the progress difference between the preparation plan 23h and the preparation result 43d is within a predetermined difference. In addition, the progress management unit 12 determines that the progress is delayed and that the plan needs to be revised when the progress difference between the production plan 23g and the production result 34d is greater than the predetermined difference (production delay) or when the progress difference between the preparation plan 23h and the preparation result 43d is greater than the predetermined difference (preparation delay).

[0057] Note that even if the production result 34d is ahead of the production plan 23g and the preparation result 43d for the next production (lot) is progressing smoothly, if there is a possibility that the preparation of the replacement cart 5 will not be completed in time and any of the component mounting lines L1 to L3 will stop before the start of production, the progress management unit 12 determines that the plan needs to be revised. That is, the progress management unit 12 determines whether the plan needs to be revised based not only on the progress difference between the production plan 23g and the production result 34d and the progress difference between the preparation plan 23h and the preparation result 43d, but also on the relative progress difference between the production result 34d and the preparation result 43d that have the same order number.

[0058] 3, when the progress management unit 12 determines that the plan needs to be revised, the instruction change unit 14 of the production management device 3 instructs the production planning device 6 to revise the production plan and the preparation plan. At that time, the information transmission unit 13 transmits production result information 15d and preparation result information 15e required for the plan revision to the production planning device 6. The plan communication unit 20 of the production planning device 6 stores the received production result information 15d and preparation result information 15e as production result 23i and preparation result 23j in the plan storage unit 23. The plan communication unit 20 may obtain the production result 23i from the line management device B1, B2, or B3, and the preparation result 23j from the preparation work management device 7.

[0059] The revised plan making unit 22 of the production planning device 6 executes a simulation based on the order information 23a, the product information 23b, the line configuration information 23c, the material information 23d, and the cart information 23e, as well as the production results 23i and the preparation results 23j, to create (make) a revised revised production plan 23k and a revised preparation plan 23m. The created revised production plan 23k and revised preparation plan 23m are stored in the plan storage unit 23. For example, in the revised production plan 23k, the component mounting lines L1 to L3 that produce mounted boards and the production order of the lots X1 to X10 are changed (revised). Also, in the revised preparation plan 23m, the number of workers W, the order of the preparation work, the cart groups Z1 to Z6 that are the targets of the preparation work, and the like are changed (updated).

[0060] 3, the plan communication unit 20 transmits the created revised production plan 23k and revised preparation plan 23m to the production management device 3. The number issuing unit 11 of the production management device 3 associates the received revised production plan 23k and revised preparation plan 23m with an order number based on the production order information 15a, and stores them as revised production plan information 15h and revised preparation plan information 15i in the management storage unit 15. As a result, the production progress of the lot whose plan has been revised in the production management device 3 is managed based on the revised production plan information 15h and revised preparation plan information 15i.

[0061] The plan communication unit 20 also transmits the created corrected production plan 23k to the line management device B1, B2 or B3 in charge. The off-line communication unit 30 of the line management device B1, B2 or B3 in charge stores (updates) the received corrected production plan 23k as a production plan 34b in the line storage unit 34. As a result, the line management device B1, B2 or B3 in charge manages the production work based on the corrected production plan 34b. The plan communication unit 20 also transmits the created corrected preparation plan 23m to the preparation work management device 7. The preparation communication unit 40 of the preparation work management device 7 stores (updates) the received corrected preparation plan 23m as a preparation plan 43b in the preparation storage unit 43. As a result, the preparation work management device 7 manages the preparation work based on the corrected preparation plan 43b.

[0062] In this way, the progress management unit 12 of the production management device 3 manages the production progress of the work by linking the production instruction information 15b, preparation instruction information 15c, production performance information 15d, and preparation performance information 15e acquired by the information acquisition unit 10 with information identifying the work (board). Then, the instruction change unit 14 of the production management device 3 issues an instruction to change the plan to the production planning device 6 based on the progress difference, whereby the production instructions 34c given by each of the line management devices B1-B3 to the production work bodies (production equipment including component mounting devices M3-M6) or the preparation instructions 43c given by the preparation work management device 7 to the preparation work bodies (work terminal T, transport vehicle V, placement work support device 4) are changed.

[0063] Next, an example of management of production progress by the production management device 3 will be described with reference to Figs. 6 and 7. Fig. 6 is an explanatory diagram of an example of smooth production progress of mounted boards based on a production plan and preparation plan drawn up by the component mounting system 1. Fig. 7 is an explanatory diagram of an example of a delay occurring in the production progress of mounted boards based on a production plan and preparation plan drawn up by the component mounting system 1. Figs. 6 and 7 respectively show the status of a current time 1 where the production progress has progressed and a current time 2 where the production progress has progressed further, with respect to the drawn up production plan 23g and preparation plan 23h shown in Fig. 5. The parts shown with diagonal lines in the diagrams indicate that the production work or preparation work has been completed (partially completed).

[0064] 6, at the present time 1, the production progress of lot X2 being produced on component mounting line L1 is ahead of the production plan 23g. Also, the production progress of lot X3 being produced on component mounting line L2 is slightly behind the production plan 23g. Also, the production of lot X1 on component mounting line L3 has been completed in accordance with the production plan 23g. Also, in the preparation area As, the preparation tasks of preparation task numbers Y1 to Y4 have been completed, and the preparation task of preparation task number Y5 is progressing in accordance with the preparation plan 23h. Therefore, the progress management unit 12 determines that all the production tasks and preparation tasks are progressing smoothly based on the progress difference calculated by the progress difference calculation unit 12a.

[0065] In Fig. 7, at present time 2, the production work of lot X5 on component mounting line L1 and lot X6 on component mounting line L2 are progressing according to production plan 23g. The preparation work is also progressing according to preparation plan 23h, and preparation work for cart group Z1 with preparation work number Y7 has been completed. However, the production work of lot X4 on component mounting line L3 is significantly delayed from production plan 23g. The next planned preparation work is preparation work with preparation work number Y8 for cart group Z4, which will be removed from component mounting line L3 after production of lot X4 is completed, but preparation work with preparation work number Y8 cannot be started due to the delay in production work for lot X4.

[0066] Therefore, production of lot X8, which is performed by attaching cart group Z4 to component mounting line L1 after the preparation work for preparation work number Y8, cannot be started either. Therefore, the progress management unit 12 determines that the plan needs to be revised based on the progress difference on component mounting line L3, and the instruction change unit 14 issues a change instruction to the production planning device 6. The revision plan formulation unit 22 creates (drafts) a revised preparation plan 23m that changes the target of the preparation work for preparation work number Y8, for example, from cart group Z4 to cart group Z2 or cart group Z3 stored in the preparation area As, and a revised production plan 23k associated with the change in the preparation work.

[0067] Next, a production management method by the production management device 3 will be described with reference to the flow of Fig. 8. Fig. 8 is a flow diagram of a production management method by the production management device 3 according to an embodiment of the present disclosure. First, the information acquisition unit 10 acquires production plan information 15f and preparation plan information 15g from the production planning device 6 (ST1: plan acquisition step). Next, the number issuing unit 11 issues an order number based on the production order information 15a (ST2: order number issuing step).

[0068] Next, until the production of mounted boards on component mounting lines L1 to L3 is completed (No in ST3), the information acquiring unit 10 acquires production instructions 34c from line management devices B1 to B3 and links them to the corresponding order numbers (ST4: production instruction acquiring step), acquires preparation instructions 43c from preparation work management device 7 and links them to the corresponding order numbers (ST5: preparation instruction acquiring step).In addition, the information acquiring unit 10 acquires production results 34d from line management devices B1 to B3 and links them to the corresponding order numbers (ST6: production result acquiring step), and acquires preparation results 43d from preparation work management device 7 and links them to the corresponding order numbers (ST7: preparation result acquiring step).

[0069] That is, the information acquisition unit 10 acquires production plan information 15f for the work, preparation plan information 15g (ST1), production instruction information 15b (ST4) that instructs the production work body (production equipment including component mounting devices M3 to M6) to perform production work to process the work, preparation instruction information 15c (ST5) that instructs the preparation work body (work terminal T, transport vehicle V, placement work support device 4) to perform preparation work for processing the work, production result information 15d (ST6) which is the production result 34d of the production work body for the work, and preparation result information 15e (ST7) which is the preparation result 43d of the preparation work body for the work (information acquisition process).

[0070] 8, the progress difference calculation unit 12a then calculates a progress difference between the work production plan 23g and the production result 34d based on the production plan information 15f and the production result information 15d. The progress difference calculation unit 12a also calculates a progress difference between the preparation plan 23h and the preparation result 43d based on the preparation plan information 15g and the preparation result information 15e (ST8: progress difference calculation step).

[0071] Next, the progress management unit 12 judges whether or not the plan needs to be revised based on the calculated progress difference (ST9: plan revision judgment step). If the plan does not need to be revised (No in ST9), the process returns to the production end judgment step (ST3) and the production end judgment step (ST3) to the plan revision judgment step (ST9) are repeatedly executed. That is, the production progress of the work is managed by linking the acquired production instruction information 15b, preparation instruction information 15c, production result information 15d, and preparation result information 15e to information that identifies the work.

[0072] If the plan needs to be revised (Yes in ST9), the instruction change unit 14 issues a change instruction to the production planning device 6 (ST10: plan revision instruction process). That is, a change instruction is issued to change the instruction to the production work body or the instruction to the preparation work body based on the progress difference. The production planning device 6 that receives the change instruction creates (drafts) revised production plan information 15h and revised preparation plan information 15i. Next, the information acquisition unit 10 acquires the revised production plan information 15h and revised preparation plan information 15i from the production planning device 6 (ST11: revised plan acquisition process). Next, the process returns to the order number issuing process (ST2) where a new order number is issued, and the production progress is managed based on the revised plan (revised production plan information 15h, revised preparation plan information 15i).

[0073] That is, the modified production plan information 15h and the modified preparation plan information 15i, which are at least partially added, deleted, or modified from the production plan information 15f, are further acquired (ST10), and instructions to the production work body or instructions to the preparation work body are changed based on the modified production plan information 15h, the modified preparation plan information 15i, the production result information 15d, and the preparation result information 15e. In this way, each piece of information stored in the management storage unit 15 is linked on a board-by-board basis by the order number and the board number. This makes it possible to easily grasp the progress status of the entire production floor F.

[0074] Next, another embodiment of the component mounting system 1 (progress management system) will be described with reference to Fig. 9. Fig. 9 is an explanatory diagram of another example of a data structure used in the component mounting system 1 (progress management system) according to another embodiment of the present disclosure. In this other embodiment, the production planning device 6 associates an order number with the production plan 23g and the preparation plan 23h and transmits them to the line management devices B1 to B3 and the preparation work management device 7, which is different from the above-mentioned component mounting system 1 (progress management system). That is, the planning unit 21 of the production planning device 6 associates the order number included in the order information 23a with the created production plan 23g and preparation plan 23h and stores them in the plan storage unit 23.

[0075] The plan communication unit 20 of the production planning device 6 transmits the production plan 23g associated with the order number to the line management devices B1-B3, and transmits the preparation plan 23h associated with the order number to the preparation work management device 7. The off-line communication unit 30 of each of the line management devices B1-B3 associates the order number included in the production plan 23g with a production instruction 34c and a production result 34d, and transmits them to the production management device 3. The preparation communication unit 40 of the preparation work management device 7 associates the order number included in the preparation plan 23h with a preparation instruction 43c and a preparation result 43d, and transmits them to the production management device 3.

[0076] 9, the information acquisition unit 10 of the production management device 3 stores production instruction 34c associated with the order number as production instruction information 15b, production result 34d associated with the order number as production result information 15d, preparation instruction 43c associated with the order number as preparation instruction information 15c, and preparation result 43d associated with the order number as preparation result information 15e in the management storage unit 15. As a result, the production instruction information 15b, production result information 15d, preparation instruction information 15c, and preparation result information 15e stored in the management storage unit 15 are associated with the order number in the same manner as in FIG.

[0077] As described above, the data structure including the production plan information 15f of the work, the production instruction information 15b instructing the production work of processing the work to the production work body (production equipment including the component mounting devices M3 to M6), the preparation instruction information 15c instructing the preparation work body (the work terminal T, the transport vehicle V, the placement work support device 4) to perform the preparation work for processing the work, the production result information 15d which is the production result 34d of the production work body for the work, and the preparation result information 15e which is the preparation result 43d of the preparation work body for the work is used by the progress management system (component mounting system 1) to specify the production progress of the work and manage the production progress of the work based on the production instruction information 15b, the preparation instruction information 15c, the production result information 15d, and the preparation result information 15e. This makes it possible to easily grasp the progress situation of the entire production floor F.

[0078] Although omitted in the above explanation for the sake of brevity, the placement operation support device 4 may integrate the preparation instructions 43c for multiple workpieces and instruct them to the worker W. For example, it may be more efficient to perform preparation work simultaneously in parallel for multiple workpieces whose production start times are close. In this case, if an order number is associated with each of the preparation work performed by the worker W, it is possible to manage which workpieces are progressing smoothly or delayed among the preparation work for each of the multiple workpieces.

[0079] Also, the line management devices B1-B3 may integrate production instructions 34c for multiple workpieces and issue instructions to the component mounting lines L1-L3. For example, the component mounting devices M3-M6 may have two lanes that transport workpieces in parallel, and may perform parallel production work on different types of workpieces in each lane. In such a case, if the production instructions 34c issued by the component mounting devices M3-M6 for each workpiece are linked to an order number, it is possible to manage which of the multiple workpieces is progressing smoothly or delayed.

[0080] Furthermore, although the arrangement work has been described as a preparatory work, the following operations may also be included in the preparatory work in addition to the arrangement work: an operation of taking a screen mask out of a storage shelf, an operation of removing solder adhering to a used screen mask, an operation of taking parts required for production out of a storage shelf, an operation of counting the remaining number of parts that have been used in production but are half-used, an operation of returning parts that have been used in production but are half-used to a storage shelf (including an automated warehouse and a humidity-controlled warehouse), an operation of moving a cart 5 used in production to a specific position in the preparation area As, an operation of returning a cart 5 used in production to the preparation area As and moving it to a storage position for storage until the next use, an operation of preparing a suction nozzle to be used in production, an operation of returning a suction nozzle used in production to a storage shelf (including a nozzle storage device), an operation of counting the number of suctions that have elapsed, a predetermined period of time, or an operation of returning a suction nozzle that has been ... The tasks may include operations such as maintaining a suction nozzle that has an interlock set to limit use, preparing a mounting head to be used in production, returning a mounting head used in production to a storage shelf, maintaining a mounting head that has an interlock set to limit use or a specified number of operations, a specified period, or use, returning a tape feeder used in production to a storage shelf, maintaining a tape feeder that has an interlock set to limit use or a specified number of suction operations, a specified period, or use, removing solder to be used in production from a storage shelf (refrigerator), stirring solder to be used in production, and recovering solder used in production for use in the next production run.

[0081] Furthermore, these tasks can be divided into pre-preparation tasks performed before production and post-preparation tasks performed after production, depending on the dependencies before and after production. An example of a task that has a pre-production dependency is placement work. An example of a task that has a post-production dependency is the task of removing solder that has adhered to a screen mask after use. For tasks that may or may not have dependencies both before and after production, pre-preparation tasks and post-preparation tasks are set according to the type of parts to be produced, the production floor F, and the worker W, and by linking an order number to each of the pre-preparation tasks and post-preparation tasks and managing the work, the progress of the work can be managed with greater precision.

[0082] The same effect can be achieved in the case of managing a plurality of transport vehicles V. To explain in more detail, in a transport vehicle management device that individually controls the transport vehicles V, in order to efficiently control the transport vehicles V, in the case where one transport vehicle V transports a plurality of workpieces with close production start times or materials for different workpieces with close supply times, if an order number is linked to each of the placement operations (or transport routes) performed by the transport vehicle V, it is possible to manage which workpieces are progressing smoothly or delayed during the transport operations.

[0083] The progress management system (component mounting system 1) described above is configured with multiple computers (production management device 3, production planning device 6, line management devices B1-B3, preparation work management device 7), but the progress management system is not limited to this configuration. For example, the processing units and stored information of the progress management system may be consolidated into one computer (for example, production management device 3).

[0084] That is, the production management device 3 may make a production plan and a preparation plan, manage the production work of the component mounting lines L1 to L3, and manage the preparation work of the preparation work bodies. For example, the information acquisition unit 10 acquires corrected production plan information 15h in which at least a part of the production plan information 15f is added, deleted, or corrected. Then, the instruction change unit 14 may change the instruction to the production work body or the instruction to the preparation work body based on the corrected production plan information 15h, the production performance information 15d, and the preparation performance information 15e. In addition, all or a part of the multiple computers (the production management device 3, the production plan making device 6, the line management devices B1 to B3, and the preparation work management device 7) in the progress management system may be provided in a cloud via a server.

[0085] The worker W does not have to be a human being, and may be any preparatory work object capable of performing preparatory work, such as a robot mechanism equipped with an end effector or an automated storage unit for storing components.

[0086] In addition, although the above description has been given using the dolly 5, the present disclosure is also applicable to a production form that does not use the dolly 5. Instead of using the dolly 5, the transport vehicle V may transport a magazine that stores materials. In other words, in the preparation area As, a preparation work of preparing materials in the magazine instead of using the dolly 5 may be performed.

[0087] In the above, the management of the production progress of mounted boards has been described using component mounting lines L1 to L3, which mount components on boards, as an example of a production line, but the management of the production progress is not limited to this. For example, the production line may be a semiconductor production line that manufactures semiconductors. It may also be an assembly production line that assembles electrical equipment. It may also be a food processing line that produces processed food products.

[0088] Although the term "pre-preparation work" is used above, the terms "pre-setup work" and "pre-production work" may be used as alternative and equivalent terms. Also, although the term "post-preparation work" is used above, the terms "post-setup work" and "post-production work" may be used as alternative and equivalent terms.

[0089] The steps in the production management method may be executed by a computer (computer system). The present disclosure can be realized as a program for causing a computer to execute the steps included in the production management method. Furthermore, the present disclosure can be realized as a non-transitory computer-readable recording medium, such as a CD-ROM, on which the program is recorded.

[0090] For example, when the present disclosure is realized by a program (software), each step is executed by executing the program using hardware resources such as a computer's CPU, memory, input / output circuit, etc. In other words, each step is executed by the CPU acquiring data from the memory or input / output circuit, etc., performing calculations, and outputting the calculation results to the memory or input / output circuit, etc.

[0091] Furthermore, each of the components included in the component mounting system 1 of the above embodiment may be realized as a dedicated or general-purpose circuit.

[0092] Furthermore, each of the components included in the component mounting system 1 of the above-described embodiment may be realized as an LSI (Large Scale Integration) which is an integrated circuit (IC: Integrated Circuit).

[0093] Furthermore, the integrated circuit is not limited to an LSI, and may be realized by a dedicated circuit or a general-purpose processor. A programmable FPGA (Field Programmable Gate Array) or a reconfigurable processor in which the connections and settings of circuit cells within an LSI can be reconfigured may also be used.

[0094] Furthermore, if an integrated circuit technology that can replace LSI emerges due to advances in semiconductor technology or a different derivative technology, naturally, that technology may be used to integrate the components included in component mounting system 1.

[0095] In addition, the present disclosure also includes forms obtained by applying various modifications to the embodiments that a person skilled in the art may conceive, and forms realized by arbitrarily combining the components and functions of each embodiment within the scope that does not deviate from the spirit of the present disclosure. [Industrial Applicability]
