Abstract
Description
Production management device, production management method, and production management program
[0001] The present disclosure relates to a production management device, a production management method, and a production management program that manage the production of mounted boards by a component mounting device.
[0002] A component mounting device that produces mounted boards is equipped with components such as tape feeders and nozzles depending on the type of mounted board being produced. These components are removed from the component mounting device and replaced with replacement components when the type of board being produced is changed, when a component breaks down, or when component maintenance is performed. The components used and stored on the component mounting line are of vast variety and quantity, and therefore must be managed appropriately (see, for example, Patent Document 1). Patent Document 1 discloses a component mounting system that allocates components to be used in advance based on a production plan, allowing the necessary components to be used when needed.
[0003] Japanese Patent Application Publication No. 2013-243243
[0004] However, in conventional technologies including Patent Document 1, although the necessary parts can be used when needed by allocating them in advance, the component mounting system needs to reserve more parts than can be mounted on the component mounting device, and it is difficult to properly keep track of the huge number of parts, so there is room for further improvement.
[0005] Therefore, an object of the present disclosure is to provide a production management device, a production management method, and a production management program that can appropriately grasp detachable members used in a component mounting device.
[0006] The production management device of the present disclosure includes an estimation unit that estimates, for each component, an estimated operation volume of the component when the mounting board is produced in accordance with the production plan, based on information related to components that are attached to and detached from a component mounting device that produces mounting boards with components mounted thereon, and information related to a production plan for producing the mounting boards; an acquisition unit that acquires actual operation volumes of the component that produced the mounting boards in accordance with the production plan; and a display unit that compares and displays the estimated operation volumes with the actual operation volumes.
[0007] Another production management device of the present disclosure includes an acquisition unit that acquires actual operating volumes of multiple components that are attached to and detached from a component mounting device that produces mounting boards on which components are mounted, and a display unit that displays the actual operating volumes for each of the components over a predetermined period.
[0008] The production management method disclosed herein estimates, for each component, an estimated operating volume of the component when the mounting board is produced in accordance with the production plan, based on information related to components that are attached to and detached from a component mounting device that produces mounting boards with components mounted thereon, and information related to a production plan for producing the mounting boards; obtains actual operating volumes of the components that produced the mounting boards in accordance with the production plan; and compares the estimated operating volumes with the actual operating volumes and displays the results on a display unit.
[0009] The production management program of the present disclosure causes a computer to execute the production management method according to claim 12.
[0010] According to the present disclosure, it is possible to appropriately grasp detachable members used in a component mounting device.

[0012] Hereinafter, with reference to the accompanying drawings as appropriate, detailed descriptions of embodiments specifically disclosing a production management device, a production management method, and a production management program according to the present disclosure will be provided. However, more detailed descriptions than necessary may be omitted. For example, detailed descriptions of well-known matters and redundant descriptions of substantially identical configurations may be omitted. This is to avoid unnecessary redundancy in the following description and to facilitate understanding by those skilled in the art. Note that the accompanying drawings and the following description are provided to enable those skilled in the art to fully understand the present disclosure, and are not intended to limit the subject matter recited in the claims.
[0013] An embodiment of the present disclosure will be described in detail below with reference to the drawings. The configurations, shapes, and the like described below are merely examples for explanation and may be modified as appropriate depending on the specifications of the component mounting system, component mounting line, management computer (production management device), component mounting device, and the like. Corresponding elements in all drawings will be denoted by the same reference numerals below, and duplicated descriptions will be omitted. In FIG. 1 and in some portions described below, two axes perpendicular to each other in a horizontal plane are shown: an X-axis in the substrate transport direction (the left-right direction in FIG. 1 ), and a Y-axis perpendicular to the substrate transport direction (the up-down direction in FIG. 1 ). In FIG. 2 and in some portions described below, a Z-axis (the up-down direction in FIG. 2 ) is shown as a height direction perpendicular to the horizontal plane.
[0014] First, the configuration of component mounting system 1 will be described with reference to FIG. 1. FIG. 1 is a configuration explanatory diagram of component mounting system 1 according to one embodiment of the present disclosure. Component mounting system 1 is configured such that three component mounting lines L1 to L3 arranged on floor F are connected by a wired or wireless communication network 2 and managed by a management computer 3. Component mounting lines L1 to L3 are arranged in production area A1 provided on floor F. As described below, each component mounting line L1 to L3 is configured by connecting multiple production devices including a printing device and a component mounting device, and has the function of producing mounted boards with components mounted on boards. Note that component mounting system 1 does not need to have three component mounting lines L1 to L3; one, two, four or more lines may be used.
[0015] In FIG. 1 , a placement work support device 4 is placed in a setup area A2 provided on floor F. The placement work support device 4 is connected to a management computer 3 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. The cart 5 is a member that is attached to and detached from the component mounting device. A plurality of carts 5 are placed in the setup area A2 while placement work is being performed or after the completion of placement work. The replacement carts 5 in the setup area A2, including the carts 5 connected to the placement work support device 4, can perform placement work in parallel with the production of mounted boards on component mounting lines L1 to L3.
[0016] 1, a preparation area A3 provided on floor F stores a plurality of carts 5 that have been collected from production area A1 and are waiting for placement work without being transported to setup area A2. Also stored in preparation area A3 are components that are attached to and detached from component mounting devices, such as component supply devices 12 (feeders), mounting heads 15, holders 16 (suction nozzles), and reels 14 (see FIG. 2) used in the production devices arranged on floor F.
[0017] 1, a maintenance support device 6 is placed in a maintenance area A4 provided on floor F. The maintenance support device 6 is connected to a management computer 3 via a communication network 2. The maintenance support device 6 has the function of automatically performing maintenance work on the component supply devices 12 (feeders), mounting heads 15, and holders 16 (suction nozzles) that are attached and subject to maintenance. A storage area A5 provided on floor F stores the component supply devices 12, mounting heads 15, holders 16, etc. before maintenance work.
[0018] When changing the type of mounted board produced on component mounting lines L1 to L3, worker W moves the replacement cart 5 that has completed placement work in setup area A2 to component mounting lines L1 to L3 and performs a product type changeover work (exchange) by replacing it with the cart 5 attached to the component mounting device. In the product type changeover work, worker W also moves replacement parts stored in preparation area A3, such as the screen mask, component supply device 12, mounting head 15, holder 16, and reel 14, to component mounting lines L1 to L3 and replaces them.
[0019] The division of each area on floor F is not limited to the above example, and can be freely changed depending on the layout of floor F. For example, preparation area A3 and storage area A5 may not be divided, but may be set as areas for temporarily storing components waiting for placement work, preparation work, and maintenance work. Furthermore, setup area A2 and preparation area A3 may not be divided, but may be set as areas for performing placement work and preparation work.
[0020] 1 , workers W performing various tasks on floor F carry information reading terminals T. The information reading terminals T read information identifying components recorded in barcodes, two-dimensional codes, and RFID tags attached to components such as carts 5, component supply devices 12, mounting heads 15, and holders 16. The information reading terminals T also have the function of displaying the read information identifying the components on a display unit to accept the details of the tasks performed by the workers W, and transmitting the information identifying the components and the details of the tasks performed by the workers W to the management computer 3 or the like via wireless communication. The workers W operate the information reading terminals T to identify the components and input the details of the tasks when attaching or detaching components to or from the component mounting devices M2 to M5, the placement work support device 4, or the maintenance support device 6, or when moving components between areas.
[0021] Next, the detailed configuration of component mounting lines L1 to L3 will be described with reference to Figure 1. Component mounting lines L1 to L3 have the same configuration, and only component mounting line L1 will be described below. Component mounting line L1 is configured by connecting production equipment, such as printing device M1, component mounting devices M2 to M5, and reflow device M6, in series, in that order from upstream (left side of the page) to downstream (right side of the page) in the board transport direction. The production equipment is connected to management computer 3 via communication network 2. Note that component mounting line L1 is a group of production equipment connected via communication network 2, and the production equipment does not necessarily have to be physically connected to each other.
[0022] In Figure 1, printing device M1 has the function of printing paste-like cream solder onto a board through a screen mask. Component mounting devices M2 to M5 have the function of picking up components supplied from a component supply unit using a holding unit 16 (suction nozzle) attached to a mounting head 15, transporting them to mounting points on the board where the cream solder has been printed, and mounting them. In other words, component mounting devices M2 to M5 have the function of producing mounted boards on which components have been mounted. Reflow device M6 has the function of heating the board on which components have been mounted to melt the cream solder, then solidifying it, thereby soldering the components to the board.
[0023] The management computer 3 performs processes such as production management of the mounted boards manufactured on the component mounting lines L1 to L3, and creation and downloading of programs and data required for manufacturing mounted boards for each production device. The management computer 3 also functions as a production management device that estimates the operating amounts (operating time, number of uses) of the members (carts 5, component supply devices 12, mounting heads 15, holders 16) attached to and detached from the component mounting devices M2 to M5, and also acquires, compares, and displays the operating amount results.
[0024] Next, the configuration of component mounting devices M2 to M5 will be described with reference to FIG. 2. FIG. 2 is a front view showing the configuration of the main parts of component mounting devices M2 to M5 provided on component mounting lines L1 to L3 according to an embodiment of the present disclosure. A component supply unit 11 is provided on the front and rear sides of each of component mounting devices M2 to M5. The component supply unit 11 is equipped with a carriage 5 having a feeder base 13 on top thereof, which has multiple slots arranged in parallel and on which a component supply device 12 (tape feeder) is placed in each slot. On the carriage 5, multiple reels 14 are held in parallel below the component supply devices 12, on which carrier tape for storing components is wound and stored. The component supply device 12 transports the carrier tape pulled out from the reel 14 inside, sequentially supplying the components stored on the carrier tape to the component mounting devices M2 to M5.
[0025] Each of the component mounting devices M2 to M5 has a mounting head 15 equipped with a holder 16, such as a suction nozzle, that holds components for mounting them on a board. The mounting head 15 is moved by a head movement mechanism (not shown) between the component supply unit 11 and a board held at a mounting position by a lane that transports the board. This performs a component mounting operation in which the holder 16 picks up components from the component supply device 12 of the component supply unit 11 and mounts them at the mounting position on the board. The component supply device 12, the cart 5, the holder 16, and the mounting head 15 are detachable from the component mounting devices M2 to M5, and components corresponding to the type of board to be mounted are attached to the component mounting devices M2 to M5.
[0026] Next, the configuration of the component mounting system 1 will be described with reference to FIGS. 3 and 4 . FIG. 3 is a block diagram illustrating the configuration of the component mounting system 1 according to an embodiment of the present disclosure. FIG. 4 is a diagram illustrating an example of the actual operation volume and waiting time of the component supply device 12 attached to and detached from the component mounting devices M2 to M5 according to an embodiment of the present disclosure. Here, the configuration related to the function of the management computer 3 as a production management device, which estimates the operation volume of the components attached to and detached from the component mounting devices M2 to M5 (cart 5, component supply device 12, mounting head 15, and holder 16), acquires the actual operation volume, and compares and displays it on the display unit, will be described. FIG. 4 shows an example of the actual operation volume and various waiting times of the component supply device 12. In the following description, the symbols shown in FIG. 4 will be referenced as appropriate. The component mounting lines L1 to L3 have the same configuration, and the following description will focus on the component mounting line L1. Furthermore, the devices included in the component mounting line L1 have the same configuration, and the following description will focus on the component mounting device M2.
[0027] 3, component mounting apparatus M2 includes an operation control unit 20, an operation unit 21, an apparatus memory unit 22, a monitoring unit 23, and an apparatus communication unit 24. The operation control unit 20 controls the operation unit 21 based on various data stored in the apparatus memory unit 22, thereby controlling the component mounting operation by component mounting apparatus M2. The operation control unit 20 controls the solder printing operation in printing apparatus M1 and the board heating operation in reflow apparatus M6.
[0028] The monitoring unit 23 monitors events related to the use of components in the component mounting device M2, such as the supply of components by the component supply device 12 (tape feeder) and the suction of components by the holder 16 (suction nozzle), and when an event occurs, notifies the management computer 3 of the operating time, number of uses, etc. The monitoring unit 23 also monitors the occurrence of events in which a component is removed from the component mounting device M2 due to a malfunction or other reason that occurs in the component mounting device M2 during the production of mounted boards, and when an event occurs, notifies the management computer 3 of information identifying the removed component and the time of removal, information identifying the component installed as a replacement component and the time of installation, etc. The device communication unit 24 is a communication interface, and sends and receives signals and data to and from other devices and the management computer 3 via the communication network 2.
[0029] 3, the management computer 3 includes a management control unit 30, a management storage unit 31, an estimation unit 32, a collection unit 33, an acquisition unit 34, a calculation unit 35, a display processing unit 36, an input unit 37, a display unit 38, a wireless communication unit 39, and a management communication unit 40. The input unit 37 is an input device such as a keyboard, a touch panel, or a mouse, and is used for inputting operation commands and data. The display unit 38 is a display device such as a liquid crystal panel, and displays various screens such as an operation screen for operation by the input unit 37, as well as various information.
[0030] The wireless communication unit 39 exchanges data via wireless communication with the information reading terminal T carried by the worker W. The management communication unit 40 is a communication interface, and exchanges signals and data with the devices on the component mounting lines L1 to L3, the placement work support device 4, and the maintenance support device 6 via the communication network 2. Note that the management computer 3 may exchange data with the devices on the component mounting lines L1 to L3 via a line management device that manages each of the component mounting lines L1 to L3.
[0031] The management control unit 30 is a computing device such as a CPU, and manages the component mounting system 1 based on information stored in the management storage unit 31. The management storage unit 31 is a storage device, and stores, in addition to component mounting data, production plan information 31 a, mounting board information 31 b, member information 31 c, maintenance information 31 d, estimated operation amount 31 e, actual result information 31 f, actual operation amount 31 g, waiting time information 31 h, and the like.
[0032] 3, production plan information 31a is created in advance by a production plan creation device (not shown) or the like. The production plan information 31a includes information related to a production plan for producing mounted boards on which components are mounted on component mounting lines L1 to L3. For example, the production plan information 31a includes production plans such as the type of mounted boards to be produced, the production quantity, the component mounting lines L1 to L3 that produce the mounted boards, the number of components to be used for each type of component (cart 5, component supply device 12, mounting head 15, holder 16) to be attached to component mounting devices M2 to M5, the scheduled production start date and time, and the unit production time (takt time) for producing one mounted board.
[0033] The production plan information 31a also includes information related to the production plan, including the production time for producing the mounting boards in the production area A1, the setup time for changing the parts used in production in the setup area A2 so that they can be used in the next production run, the preparation time for preparing the parts to produce the mounting boards in the preparation area A3, the maintenance time for maintaining the parts in the maintenance area A4, and the storage time for storing the parts in the storage area A5.
[0034] 3, the mounting board information 31b includes, for each type of mounting board produced on the component mounting lines L1 to L3, the type of components to be mounted on the board, the mounting position, etc. The component information 31c stores, for each component (cart 5, component supply device 12, mounting head 15, holder 16) present on floor F, information identifying the component, the type of component (8 mm single, 8 mm double, 16 mm depending on the tape width of component supply device 12, 16, 8, 3 depending on the number of holders 16 of mounting head 15, 0402, 0201 depending on the dimensions of components picked up by holder 16), the state of the component (mounted position, stored position, etc.), the cumulative usage period of the component (cumulative number of uses), the usage period since the most recent maintenance (number of uses), etc.
[0035] The maintenance information 31d stores, for each type of component, the maximum usable period (maximum number of times usable) that the component can be used before being discarded, and the maintenance period (number of times usable between maintenances) that the component can be used between maintenances.
[0036] In FIG. 3 , the estimation unit 32 estimates, for each component, the minimum number of components (number of members), the minimum number of uses, and the minimum operating time required when producing a mounting board in accordance with the production plan, based on the production plan information 31 a, mounting board information 31 b, component information 31 c, and maintenance information 31 d, and stores these in the management memory unit 31 as estimated operating amount 31 e.
[0037] Specifically, the estimation unit 32 allocates components to be mounted on component mounting devices M2 to M5 based on the production plan, and calculates the minimum number of uses and operating time for each component used in producing the mounting board based on the unit production time of the mounting board, the number of components produced, and the component mounting positions (number of components).
[0038] In another embodiment, the estimation unit 32 allocates components taking into consideration the maintenance of each component, and calculates the minimum number of uses and operating time. Specifically, the estimation unit 32 allocates components to be used in production from among components whose remaining number of uses until the next maintenance (number of uses between maintenances - number of uses since the most recent maintenance) is longer than the number of uses required for production.
[0039] The estimation unit 32 also estimates the completion time of maintenance work for components in the maintenance area A4 based on the maintenance work time for each component. If there are any components whose maintenance work will be completed by the start of production of the mounting board, the estimation unit 32 adds those components to the list of candidates for components to be allocated. Furthermore, if there are no components whose remaining number of uses is longer than the required number of uses, the estimation unit 32 allocates components so that multiple components are used in place of each other. Next, the estimation unit 32 calculates the number of allocated components, the number of uses, and the operating time, and stores these as the estimated operating amount 31e.
[0040] 3 and 4, the collection unit 33 collects information about events that have occurred in each device from the monitoring unit 23 provided in each device on the component mounting lines L1 to L3. The collection unit 33 also collects information about setup work from the placement work support device 4. The collection unit 33 also collects information about maintenance work from the maintenance support device 6. The collection unit 33 also collects information about work performed by the worker W on the components from the information reading terminal T. The collection unit 33 then stores the various types of collected information in the management storage unit 31 as performance information 31f.
[0041] Specifically, the collection unit 33 collects the setup start time T1 at which the placement work (component setup work) of placing the component supply device 12 (feeder) and the reel 14 on the replacement cart 5 starts, and the setup end time T2 at which the placement work ends, from the placement work support device 4 and the information reading terminal T. In addition, the collection unit 33 collects the times at which components are attached to the component mounting devices M2 to M5 (attachment start time T4) and the times at which components are removed (removal end time T7) from the monitoring units 23 of the component mounting devices M2 to M5 and the information reading terminal T.
[0042] The collection unit 33 also collects from the information reading terminal T a storage start time T11 (storage area arrival time T10) when storage of the component in storage area A5 begins, and a storage end time T12 (maintenance area arrival time T13) when storage ends. The collection unit 33 also collects from the maintenance support device 6 and the information reading terminal T a maintenance start time T14 when maintenance of the component begins, and a maintenance end time T15 when maintenance ends. The collection unit 33 also collects from the information reading terminal T a preparation start time T17 when preparation of the component in preparation area A3 begins, and a preparation end time T18 when preparation ends.
[0043] 3 and 4, the acquisition unit 34 acquires the actual operating amount 31g (number of times used, operating time) of the components that produced the mounting board in accordance with the production plan from the performance information 31f stored in the management memory unit 31, and stores the information in the management memory unit 31.
[0044] The actual operation amount 31g includes a production time ΔT4 during which components are used to produce mounted boards in component mounting lines L1-L3 (production area A1), calculated based on the mounting start time T4 when the components are mounted on component mounting devices M2-M5 and the removal end time T7 when the components are removed. The actual operation amount 31g also includes a setup time ΔT2 during which components used in production in setup area A2 are set up for use in the next production run, calculated based on the setup start time T1 and setup end time T2 when the components are set up.
[0045] The actual operation amount 31g also includes a preparation time ΔT14 for preparing components in the preparation area A3 to produce mounted boards, which is calculated based on a preparation start time T17 and a preparation end time T18 for preparing the components. The actual operation amount 31g also includes a maintenance time ΔT12 for performing maintenance on the components in the maintenance area A4, which is calculated based on a maintenance start time T14 and a maintenance end time T15 for performing maintenance on the components. The actual operation amount 31g also includes a storage time ΔT10 for storing the components in the storage area A5, which is calculated based on a storage start time T11 when storage of the components begins and a storage end time T12.
[0046] Based on the operating time (usage time) and number of uses of the component included in the operation performance amount 31g thus acquired, the cumulative usage period (cumulative number of uses) and usage period since the most recent maintenance (number of uses) of the component included in the component information 31c are updated. The estimation unit 32 estimates the maintenance time ΔT12 of the component for which maintenance is to be performed next based on the updated component information 31c, production plan information 31a, mounting board information 31b, and maintenance information 31d. That is, the estimation unit 32 estimates the maintenance time ΔT12 from the acquired past actual operation amount 31g of the component and the production plan.
[0047] 3 and 4, the calculation unit 35 calculates various waiting times (non-operating times) when the components are not operating based on the acquired actual operating amount 31g, and stores the calculated waiting times in the management memory unit 31 as waiting time information 31h.
[0048] Specifically, the calculation unit 35 calculates, from the actual operation volume 31g, production waiting times ΔT3 and ΔT15 during which components wait for the start of production of mounted boards on component mounting lines L1 to L3 (production area A1), setup waiting times ΔT1 and ΔT5 during which components wait for the start of setup change in setup area A2, preparation waiting time ΔT13 during which components wait for the start of preparation in preparation area A3 or storage area A5, and maintenance waiting time ΔT11 during which components wait for the start of maintenance in maintenance area A4.
[0049] 4, the division into operating time and non-operating time may be changed depending on the area settings of floor F. For example, the production time ΔT4 may be the time from the production start time T5 to the production end time T6, the time from the installation start time T4 to the production start time T5 may be the production wait time ΔT3, and the time from the production end time T6 to the removal end time T7 may be the setup wait time ΔT5 or the storage time ΔT10.
[0050] In FIG. 3 , the display processing unit 36 causes the display unit 38 to display a component operation amount display screen that compares and displays an estimated operation amount 31e that would be estimated if the mounting board were produced in accordance with the production plan with an actual operation amount 31g of the components used to produce the mounting board in accordance with the production plan.
[0051] Next, an example of a member operation amount display screen 50 displayed on the display unit 38 by the display processing unit 36 will be described with reference to Fig. 5. Fig. 5 is an explanatory diagram showing an example of a member operation amount display screen 50 displayed on the display unit 38 provided in the management computer 3 (production management device) according to an embodiment of the present disclosure. The member operation amount display screen 50 is provided with a display member selection frame 51, a display item selection frame 52, a display content selection frame 53, and an operation amount display frame 54.
[0052] The display member selection frame 51 is provided with radio buttons for selecting whether to display only the component supply device 12 (component supply device), only the holder 16 (holder), only the carriage 5 (carriage), or only the mounting head 15 (mounting head) as the member to be displayed in the operation amount display frame 54. In this example, "component supply device" is selected.
[0053] 5, the display item selection frame 52 is provided with radio buttons for selecting whether the operation amount to be displayed in the operation amount display frame 54 is to be displayed as operation time (operation time display) or as the number of uses (use count display). In this example, "operation time display" is selected. The display content selection frame 53 is provided with radio buttons for selecting whether the estimated operation amount 31e and the actual operation amount 31g are to be displayed in the operation amount display frame 54 (estimated / actual display) or whether the actual operation amount 31g is to be displayed for each component selected in the display component selection frame 51 (component display). In this example, "estimated / actual display" is selected.
[0054] The operation amount display frame 54 displays a bar graph in which the estimated operation amount 31e (estimated) and actual operation amount 31g (actual) for a one-week period are stacked and standardized for each type of component supply device 12 (component) (8 mm single, 8 mm double, 16 mm, etc.) for each area in which the component is located.
[0055] Specifically, for each type of component, the display shows the production time ΔT4 (production) in the production area A1, the preparation time ΔT14 (preparation) in the preparation area A3, the preparation time ΔT2 (preparation) in the preparation area A2, the maintenance time ΔT12 (maintenance) in the maintenance area A4, and the storage time ΔT10 (storage) in the storage area A5. The actual operation volume 31g also shows the production wait times ΔT3 and ΔT15 (production), the preparation wait time ΔT13 (preparation), and the setup wait times ΔT2 and ΔT5 (preparation). The arrow buttons 55 can be operated to scroll through the displayed types of component supply devices 12.
[0056] In this way, the display unit 38 compares and displays the estimated operation amount 31e and actual operation amount 31g of the components that produced the mounted boards during a predetermined period (e.g., one week) according to the production plan (operation amount display frame 54). The display unit 38 also displays the actual operation amount 31g by distinguishing between operating time (production time ΔT4, preparation time ΔT14, setup time ΔT2, maintenance time ΔT12) and non-operating time (production wait time ΔT3, ΔT15, preparation wait time ΔT13, setup wait time ΔT2, ΔT5). By displaying the estimated and actual operation amounts by distinguishing between operating and non-operating time, the removable components (cart 5, component supply device 12, mounting head 15, holder 16) used by component mounting devices M2 to M5 can be properly identified.
[0057] Next, an example of a member operation amount display screen 56 displayed on the display unit 38 by the display processing unit 36 will be described with reference to Fig. 6. Fig. 6 is an explanatory diagram showing an example of a member operation amount display screen 56 displayed on the display unit 38 provided in the management computer 3 (production management device) according to an embodiment of the present disclosure. In this example, "component supply device" is selected in the display member selection frame 51, "operation time display" is selected in the display item selection frame 52, and "display by member" is selected in the display content selection frame 53.
[0058] The operation amount display frame 57 displays the actual operation time (actual operation amount 31g) for one day (predetermined period) of the component supply device 12 selected in the display component selection frame 51, sorted by component supply device 12 (by component). The hatching applied to the actual operation time for each component indicates different board types of mounting boards. In other words, components with the same hatching are used in the production of mounting boards of the same board type.
[0059] In this way, the display unit 38 displays the actual operation amount 31g for a predetermined period (for example, one day) for each component and for each type of mounting board (operation amount display frame 57). By displaying the actual operation amount values for each component and for each type of mounting board, it is possible to properly grasp the detachable components (cart 5, component supply device 12, mounting head 15, holder 16) used in component mounting devices M2 to M5.
[0060] Next, a production management method (production management program) for comparing estimated operation amounts 31e and actual operation amounts 31g of components (carts 5, component supply devices 12, mounting heads 15, and holders 16) attached to and detached from component mounting devices M2 to M5 and displaying the results on a display unit will be described with reference to the flow chart of Figure 7. Figure 7 is a flow diagram of a production management method according to an embodiment of the present disclosure. The following description is based on the assumption that performance information 31f on the production of mounted boards in accordance with the production plan on component mounting lines L1 to L2 is collected and stored by a collection unit 33 in a management storage unit 31 of a management computer 3 (production management device).
[0061] First, the estimation unit 32 estimates an estimated operation amount 31e of each component when the mounting board is produced according to the production plan based on the production plan information 31a, the mounting board information 31b, the component information 31c, and the maintenance information 31d (ST1: operation amount estimation step). Further, the acquisition unit 34 acquires the actual operation amount 31g of the component used to produce the mounting board according to the production plan from the performance information 31g (ST2: performance acquisition step).
[0062] 7, the calculation unit 35 then calculates various waiting times (waiting time information 31h) during which components are not operating based on the acquired actual operation amounts 31g (ST3: waiting time calculation step). The display processing unit 36 then compares the estimated operation amounts 31e with the actual operation amounts 31g and displays the results on the display unit 38 (ST4: display step) (FIG. 5). Alternatively, in the display step (ST4), the display processing unit 36 displays the actual operation amounts 31g for each component over a predetermined period on the display unit 38 (FIG. 6). This allows the user to properly identify the detachable components (carts 5, component supply devices 12, mounting heads 15, and holders 16) used by the component mounting devices M2 to M5.
[0063] As described above, the management computer 3 of this embodiment is a production management device that includes: an estimation unit 32 that estimates, for each component, an estimated operation amount 31e of the components when the mounting board is produced in accordance with the production plan, based on information (component information 31c) about the components (cart 5, component supply device 12, mounting head 15, holder 16) that are attached to and detached from component mounting devices M2 to M5 that produce mounting boards with components mounted thereon, and information about the production plan for producing the mounting boards (production plan information 31a); an acquisition unit 34 that acquires actual operation amounts 31g of the components used to produce the mounting boards in accordance with the production plan; and a display unit 38 that compares and displays the estimated operation amounts 31e and the actual operation amounts 31g. This makes it possible to appropriately grasp the detachable components used in the component mounting devices M2 to M5.
[0064] Although the embodiments of the present disclosure have been described above with reference to the drawings, it goes without saying that the present disclosure is not limited to such examples. It is clear that a person skilled in the art can conceive of various modifications, alterations, substitutions, additions, deletions, and equivalents within the scope of the claims, and it is understood that these also naturally fall within the technical scope of the present disclosure. Furthermore, the components of the above-described embodiments may be combined in any manner as long as they do not deviate from the spirit of the invention.
[0065] This application is based on a Japanese patent application (Patent Application No. 2024-056935) filed on March 29, 2024, the contents of which are incorporated herein by reference.
[0066] The production management device, production management method, and production management program disclosed herein have the effect of being able to properly grasp detachable components used in component mounting devices, and are useful in the field of mounting components onto boards.
