Description

Technical Field

[0001] This disclosure relates to a production management device, production management method, and production management procedure for managing the production of mounting plates for component mounting equipment. Background Technology

[0002] In component assembly equipment that produces mounting plates, components such as belt feeders and nozzles are installed according to the mounting plates to be produced. When the type of mounting plate to be produced is changed, when a component fails, or when a component is being maintained, these components are removed from the component assembly equipment, and replacement components are installed. Because the types and quantities of components used and stored in the component assembly line are vast, proper component management is necessary (see, for example, Patent Document 1). Patent Document 1 discloses a component assembly system capable of using necessary components at the necessary time by pre-installing components to be used based on a production plan.

[0023] In the following, embodiments of production management equipment, production management methods, and production management procedures according to this disclosure will be described in detail with appropriate reference to the accompanying drawings. However, unnecessary detailed descriptions may be omitted. For example, detailed descriptions of already known matters or repetitive descriptions of substantially the same configurations may be omitted. This is to avoid unnecessary redundancy in the following description and to facilitate understanding by those skilled in the art. The accompanying drawings and the following description are provided to enable those skilled in the art to fully understand the contents of this disclosure and are not intended to limit the subject matter described in the claims.

[0024] In the following, embodiments of the present disclosure will be described in detail with reference to the accompanying drawings. The configurations, shapes, etc., described later are examples for illustrative purposes and may be appropriately changed according to the specifications of the component mounting system, component mounting line, management computer (production management equipment), component mounting equipment, etc. In the following, corresponding elements in all the drawings are indicated by the same reference numerals, and repeated descriptions are omitted. Figure 1 In the section described later, the two axes orthogonal to each other in the horizontal plane are referred to as the X-axis in the plate conveying direction. Figure 1 The left and right directions) and the Y-axis orthogonal to the plate conveying direction (in the ... Figure 1 (Up and down directions in the middle). Figure 2 And in the section described later, the Z-axis ( Figure 2 The vertical direction (in the image) is shown as the height direction orthogonal to the horizontal plane.

[0025] First, refer to Figure 1 Describe the configuration of component installation system 1. Figure 1 This diagram illustrates the configuration of a component mounting system 1 according to an embodiment of the present disclosure. The component mounting system 1 is implemented such that three component mounting lines L1 to L3 arranged on a floor F are connected via a wired or wireless communication network 2 and managed by a management computer 3. The component mounting lines L1 to L3 are located in a production area A1 formed on the floor F. Each of the component mounting lines L1 to L3 is implemented by connecting multiple production devices, including printing equipment and component mounting equipment, which will be described later, and has the function of producing mounting plates on the plates in which components are mounted. The component mounting system 1 need not include three component mounting lines L1 to L3, and may include one, two, four, or more component mounting lines.

[0026] exist Figure 1 In this setup, a placement operation support device 4 is installed in a placement area A2 formed on the floor F. The placement operation support device 4 is connected to a management computer 3 via a communication network 2. The placement operation support device 4 is connected to a replacement carriage 5, which is the target of the placement operation described later. The carriage 5 is a component that is installed onto and removed from the component mounting equipment. Multiple carriages 5 are arranged in the placement area A2 for use during or after the placement operation. For the replacement carriages 5 in the placement area A2 (including the carriages 5 connected to the placement operation support device 4), placement operations can be performed in parallel with the production of mounting plates in the component mounting lines L1 to L3.

[0027] exist Figure 1 In the preparation area A3 formed on the floor F, multiple carriages 5 collected from the production area A1 and awaiting placement operations because they have not been transferred to the setting area A2 are stored. The preparation area A3 also stores components to be installed onto and removed from the component installation equipment, such as component supply equipment 12 (feeder), mounting head 15, retaining part 16 (nozzle), and reel 14 (see [link]). Figure 2 The component installation equipment is used in the production equipment set on floor F.

[0028] exist Figure 1 In this system, maintenance support equipment 6 is installed in maintenance area A4 formed on floor F. Maintenance support equipment 6 is connected to management computer 3 via communication network 2. Maintenance support equipment 6 has the function of automatically performing maintenance operations on component supply equipment 12 (feeder), mounting head 15, and holding part 16 (nozzle) installed as maintenance targets. In storage area A5 formed on floor F, component supply equipment 12, mounting head 15, holding part 16, etc., are stored before maintenance operations.

[0029] When the type of mounting plate to be produced in component mounting lines L1 to L3 is changed, operator W moves the replacement carriage 5, which has been arranged in setting area A2, to component mounting lines L1 to L3, and performs a type switching operation (replacement) to replace the replacement carriage 5 with the carriage 5 installed on the component mounting equipment. In the type switching operation, operator W moves the screen mask, component supply equipment 12, mounting head 15, holding part 16, reel 14, etc., which are replacement components stored in preparation area A3, to component mounting lines L1 to L3, and replaces these components.

[0030] The division of each area on floor F is not limited to the example above and can be freely changed according to the layout of floor F. For example, without division, preparation area A3 and storage area A5 can be set as areas for temporarily storing components awaiting placement, preparation, and maintenance operations. Without division, setting area A2 and preparation area A3 can be set as areas for performing placement and preparation operations.

[0031] exist Figure 1 In this system, operator W, performing various operations on floor F, carries an information reading terminal T. The information reading terminal T reads barcodes or QR codes attached to components such as carriages 5, component supply equipment 12, mounting heads 15, or retaining parts 16, or reads information recorded in RFID tags used to identify the components. The information reading terminal T has the following functions: displaying the read component identification information on a display unit to receive operator W's operation content, and wirelessly transmitting the component identification information and operator W's operation content to a management computer 3, etc. When operator W installs components onto component installation equipment M2 to M5, arranges operation support equipment 4 or maintenance support equipment 6, removes components from them, or moves components between areas, operator W identifies the components and inputs operation content through the operation information reading terminal T.

[0032] Next, we will refer to Figure 1 The detailed configuration of component mounting lines L1 to L3 is described below. Component mounting lines L1 to L3 have the same configuration, and component mounting line L1 will be described below. Component mounting line L1 is implemented by sequentially connecting production equipment such as printing equipment M1, component mounting equipment M2 to M5, and reflow equipment M6 in the board conveying direction from upstream (left side of the page) to downstream (right side of the page). The production equipment is connected to management computer 3 via communication network 2. Component mounting line L1 is a group of production equipment connected via communication network 2, and the production equipment may not be physically connected to each other.

[0033] exist Figure 1 In this process, printing equipment M1 has the function of printing solder paste onto a board via a screen mask. Component mounting equipment M2 to M5 have the function of picking up components supplied from the component supply unit via a holding part 16 (nozzle) mounted on the mounting head 15, and conveying and mounting the components to mounting points on the board on which solder paste has been printed. That is, component mounting equipment M2 to M5 have the function of producing mounting plates on a board in which components are mounted. Reflow equipment M6 has the function of heating the plate on which components are mounted to melt the solder paste, and then solidifying the solder paste to solder the components to the plate.

[0034] The management computer 3 performs processes such as production management of mounting plates manufactured in component assembly lines L1 to L3, and creating and downloading the programs and data required for manufacturing mounting plates for each production equipment. The management computer 3 has the function of a production management device, which estimates the amount of operation (operation time and number of uses) of components (carriage 5, component supply equipment 12, mounting head 15 and holding part 16) installed to and removed from component assembly equipment M2 to M5, and acquires, compares and displays the actual operation amount.

[0035] Next, we will refer to Figure 2 Describe the configuration of component installation devices M2 to M5. Figure 2 This is a front view showing the configuration of the main parts of the component mounting devices M2 to M5 arranged in component mounting lines L1 to L3 according to an embodiment of the present disclosure. A component supply unit 11 is arranged on the front and rear sides of the component mounting devices M2 to M5. In the component supply unit 11, a carriage 5 is mounted having a plurality of parallel slots and a feeder base 13 in each slot on which a component supply device 12 (belt feeder) is placed. In the carriage 5, a plurality of reels 14 are held parallel below the component supply device 12, the reels 14 winding and storing carrier tape containing components. The component supply device 12 sequentially supplies components stored in the carrier tape pulled from the reels 14 to the component mounting devices M2 to M5 while internally conveying these carrier tapes.

[0036] In the component mounting devices M2 to M5, a mounting head 15 is provided. A holding part 16, such as a suction nozzle, is mounted on the mounting head 15, which holds the component for mounting onto the plate. The mounting head 15 is moved between the component supply unit 11 and the plate held in the mounting operation position by a head moving mechanism (not shown). Accordingly, a component mounting operation is performed, in which the component removed from the component supply device 12 of the component supply unit 11 by the holding part 16 is mounted on the plate at the mounting position. The component supply device 12, the carriage 5, the holding part 16, and the mounting head 15 are components that can be mounted to and removed from the component mounting devices M2 to M5, and are mounted on the component mounting devices M2 to M5 according to the type of mounting plate to be produced.

[0037] Next, we will refer to Figure 3 and Figure 4 Describe the configuration of component installation system 1. Figure 3 This is a block diagram illustrating the configuration of a component installation system 1 according to an embodiment of the present disclosure. Figure 4This diagram illustrates an example of the actual operating volume and waiting time of component supply equipment 12 being installed into and removed from component mounting devices M2 to M5 according to an embodiment of this disclosure. Here, the configuration related to the function of the management computer 3 as a production management device will be mainly described. This function estimates the operating volume of components (carrier 5, component supply equipment 12, mounting head 15, and holding part 16) being installed into and removed from component mounting devices M2 to M5, obtains the actual operating volume, and compares and displays the actual operating volume on a display unit. Figure 4 Examples of actual operating volumes and various waiting times for component supply equipment 12 are shown. References are made appropriately in the following description. Figure 4 The reference numerals are shown in the attached figures. Component mounting lines L1 to L3 have the same configuration, and component mounting line L1 will be described below. The devices disposed in component mounting line L1 have the same configuration, and component mounting device M2 will be described below.

[0038] exist Figure 3 In this assembly, the component mounting equipment M2 includes an operation control unit 20, an operation unit 21, an equipment storage unit 22, a monitoring unit 23, and an equipment communication unit 24. The operation control unit 20 controls the operation unit 21 based on various data stored in the equipment storage unit 22, thereby controlling the component mounting operation of the component mounting equipment M2. The operation control unit 20 also controls the solder printing operation in the printing equipment M1 and the board heating operation in the reflow equipment M6.

[0039] Monitoring unit 23 monitors events related to the use of components in component mounting equipment M2 (such as component supply equipment 12 (belt feeder) supplying components and holding part 16 (nozzle) adsorbing components), and notifies management computer 3 of operation time, number of uses, etc., when an event occurs. Monitoring unit 23 also monitors events that cause components to be removed from component mounting equipment M2 due to reasons such as malfunctions occurring in component mounting equipment M2 during the production of mounting plates, and notifies management computer 3 of information for identifying the removed component and the time of removal, as well as information for identifying components attached as alternative components and the time of attachment, when such events occur. Equipment communication unit 24 is a communication interface that sends and receives signals and data from other devices and management computer 3 via communication network 2.

[0040] exist Figure 3In this system, 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, touch panel, or mouse, and is used when inputting operation commands or data. The display unit 38 is a display device such as a liquid crystal panel, and displays various information in addition to various screens such as operation screens for the input unit 37.

[0041] Wireless communication unit 39 sends and receives data wirelessly to and from information reading terminal T carried by operator W. Management communication unit 40 is a communication interface and sends and receives signals and data to and from the equipment on component assembly lines L1 to L3, the placement operation support equipment 4, and the maintenance support equipment 6 via communication network 2. Management computer 3 can send and receive data to and from the equipment on each of the component assembly lines L1 to L3 via the production line management equipment.

[0042] The management control unit 30 is a computing device such as a CPU, and manages the component installation system 1 based on the information stored in the management storage unit 31. The management storage unit 31 is a storage device, and in addition to component installation data, it also stores production plan information 31a, mounting plate information 31b, component information 31c, maintenance information 31d, estimated operation volume 31e, actual performance information 31f, actual operation volume 31g, waiting time information 31h, etc.

[0043] exist Figure 3 In this context, production planning information 31a is pre-created by production planning creation equipment (not shown). Production planning information 31a includes information about the production plan for producing mounting plates on which components are mounted in component mounting lines L1 to L3. For example, production planning information 31a includes production plans such as the type of mounting plate to be produced, the quantity to be produced, the component mounting lines L1 to L3 for producing the mounting plates, the quantity of components (carriage 5, component supply equipment 12, mounting head 15, and retaining part 16) used for each type of mounting on component mounting equipment M2 to M5, the planned production start date and time, and the unit production time (cycle time) for producing one mounting plate.

[0044] Production planning information 31a includes information about the production plan, including the production time for producing mounting plates in production area A1, the setup operation time for changing settings to use components produced in setup area A2 for the next production, the preparation time for preparing components for producing mounting plates in preparation area A3, the maintenance operation time for maintaining components in maintenance area A4, and the storage time for storing components in storage area A5.

[0045] exist Figure 3 In the mounting plate information 31b, the mounting plate information includes mounting plates for each type of plate produced in the component mounting lines L1 to L3, the type of component mounted on the plate, the mounting position, etc. In the component information 31c, for each component (carriage 5, component supply device 12, mounting head 15, and retaining part 16) present on the floor F, the information stored for identifying the component, the type of the component (8mm single row, 8mm double row, and 16mm, which are types classified due to the bandwidth difference of the component supply device 12; 16, 8, and 3, which are the number of retaining parts 16 of the mounting head 15; and 0402 and 0201, which are the dimensions of the components held by the retaining parts 16), the status of the component (installation position, storage position, etc.), the cumulative usage period (cumulative number of uses) of the component, and the usage period (number of uses) since the last maintenance, etc.

[0046] Maintenance information 31d stores, for each type of component, the maximum usable period (maximum number of uses) during the component's usable period until the component is discarded, and the maintenance period (number of uses during maintenance) during the component's usable period from the last maintenance to the next maintenance.

[0047] exist Figure 3 In the process, based on production plan information 31a, mounting plate information 31b, component information 31c, and maintenance information 31d, the estimation unit 32 estimates for each component the minimum number of components (component quantity), the minimum number of uses, and the shortest operation time required when the mounting plate is produced according to the production plan, and stores the estimated minimum number of components, the minimum number of uses, and the shortest operation time as estimated operation quantities 31e in the management storage unit 31.

[0048] Specifically, the estimation unit 32 allocates components to be installed on the component mounting equipment M2 to M5 based on the production plan, and calculates the minimum number of uses and the shortest operation time for each component used to produce the mounting plate based on the unit production time of the mounting plate, the quantity produced, and the installation position (number of components).

[0049] As another embodiment, the estimation unit 32 calculates the minimum number of uses and the shortest operation time by installing components while taking into account the maintenance of each component. Specifically, the estimation unit 32 allocates components to be used for production from those components whose remaining usable count until the next maintenance (the number of usable counts during maintenance minus the number of uses since the most recent maintenance) is greater than the number of uses required for production.

[0050] The estimation unit 32 estimates the end time of the maintenance operation for each component in maintenance area A4 based on the maintenance operation time of each component. Then, when there is a component whose maintenance operation ends before the start of the mounting plate production, the estimation unit 32 adds that component as a candidate for installation. When there is no component with more remaining usage times than the required usage times, the component is installed, thus replacing and using multiple components. Next, the estimation unit 32 calculates the number of allocated components, usage times, and operation times, and stores the number of allocated components, usage times, and operation times as the estimated operation quantity 31e.

[0051] exist Figure 3 and Figure 4 In this process, the collection unit 33 collects information about events occurring in the equipment from the monitoring unit 23 located in the equipment installed in the component installation lines L1 to L3. The collection unit 33 collects setup operation information from the setup operation support equipment 4. The collection unit 33 collects maintenance operation information from the maintenance support equipment 6. The collection unit 33 collects information about operations performed by the operator W on the components from the information reading terminal T. Then, the collection unit 33 stores the collected information of various types as performance information 31f in the management storage unit 31.

[0052] Specifically, the collection unit 33 collects from the placement operation support device 4 and the information reading terminal T the placement start time T1 and the placement end time T2 of the placement operation (component setting operation) that begins when the component supply device 12 (feeder) and reel 14 are placed on the replacement carriage 5. The collection unit 33 collects from the monitoring unit 23 and the information reading terminal T of the component installation devices M2 to M5 the time when the component is installed on the component installation devices M2 to M5 (installation start time T4) and the time when the component is removed (removal end time T7).

[0053] The collection unit 33 collects from the information reading terminal T the storage start time T11 (storage area arrival time T10) for starting to store the component in storage area A5 and the storage end time T12 (maintenance area arrival time T13) for ending storage. The collection unit 33 collects from the maintenance support device 6 and the information reading terminal T the maintenance start time T14 for starting to maintain the component and the maintenance end time T15 for ending maintenance. The collection unit 33 collects from the information reading terminal T the preparation start time T17 for starting to prepare the component in preparation area A3 and the preparation end time T18 for ending preparation.

[0054] exist Figure 3 and Figure 4 In the process, the acquisition unit 34 obtains the actual operation quantity 31g (number of uses and operation time) of the components for producing the mounting plate according to the production plan from the performance information 31f stored in the management storage unit 31, and stores the actual operation quantity 31g in the management storage unit 31.

[0055] The actual operation quantity 31g includes the production time ΔT4 for producing mounting plates of components in assembly lines L1 to L3 (production area A1). The production time ΔT4 is calculated based on the installation start time T4 for installing components onto assembly equipment M2 to M5 and the disassembly end time T7 for removing components. The actual operation quantity 31g also includes the setup time ΔT2, where the settings of components used for production in setup area A2 are changed for the next production run. The setup time ΔT2 is calculated based on the setup start time T1 and setup end time T2 for changing the component settings.

[0056] The actual operation quantity 31g includes the preparation time ΔT14 for preparing components in preparation area A3 for the production of mounting plates. The preparation time ΔT14 is calculated based on the preparation start time T17 and preparation end time T18. The actual operation quantity 31g includes the maintenance time ΔT12 for maintaining components in maintenance area A4. The maintenance time ΔT12 is calculated based on the maintenance start time T14 and maintenance end time T15. The actual operation quantity 31g includes the storage time ΔT10 for storing components in storage area A5. The storage time ΔT10 is calculated based on the storage start time T11 and storage end time T12.

[0057] Based on the component's operation time (usage time) and usage frequency included in the actual operation quantity 31g obtained in this way, the cumulative usage period (cumulative usage frequency) and usage period (usage frequency) since the last maintenance included in the component information 31c are updated. Based on the updated component information 31c, production plan information 31a, mounting plate information 31b, and maintenance information 31d, the estimation unit 32 estimates the maintenance time ΔT12 of the component to be maintained next. That is, the estimation unit 32 estimates the maintenance time ΔT12 based on the acquired past actual operation quantity 31g of the component and the production plan.

[0058] exist Figure 3 and Figure 4 In the process, the calculation unit 35 calculates various waiting times (non-operation times) during the period when the component is not operated based on the actual operation quantity 31g obtained, and stores the calculated waiting time as waiting time information 31h in the management storage unit 31.

[0059] Specifically, the calculation unit 35 calculates the production waiting time ΔT3 and ΔT15 for the component to wait for the production of the mounting plate to start in the component installation line L1 to L3 (production area A1), the setting waiting time ΔT1 and ΔT5 for the component to wait for the setting change to start in the setting area A2, the preparation waiting time ΔT13 for the component to wait for the preparation to start in the preparation area A3 or the storage area A5, and the maintenance waiting time ΔT11 for the component to wait for the maintenance to start in the maintenance area A4, based on the actual operation quantity 31g.

[0060] The classification of operation time and non-operation time is not limited to... Figure 4 The example shown can be modified according to the settings of the area of ​​floor F, etc. For example, the production time ΔT4 can be set to 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 can be set to the production waiting time ΔT3, and the time from the production end time T6 to the dismantling end time T7 can be set to the setup waiting time ΔT5 or the storage time ΔT10.

[0061] exist Figure 3 In the process, the display processing unit 36 ​​causes the display unit 38 to display a component operation quantity display screen, which compares and displays the estimated operation quantity 31e when the mounting plate is produced according to the production plan and the actual operation quantity 31g of the component when the mounting plate is produced according to the production plan.

[0062] Next, we will refer to Figure 5 An example of a component operation quantity display screen 50 displayed on a display unit 38 by a display processing unit 36 ​​is described. Figure 5This is a diagram illustrating an example of a component operation quantity display screen 50 displayed on a display unit 38 provided in a management computer 3 (production management equipment) according to an embodiment of the present disclosure. The component operation quantity display screen 50 is provided with a component selection box 51, an item selection box 52, a content selection box 53, and an operation quantity display box 54.

[0063] The component selection box 51 is equipped with radio buttons for selecting whether to display only the component supply device 12 (component supply device), only the retaining part 16 (retaining part), only the carriage 5 (carriage), or only the mounting head 15 (mounting head) as the components displayed in the operation quantity display box 54. In this example, "component supply device" is selected.

[0064] exist Figure 5 In the display item selection box 52, radio buttons are provided to select whether the operation quantity displayed in the operation quantity display box 54 is displayed as operation time (operation time display) or as usage count (usage count display). In this example, "operation time display" is selected. The display content selection box 53 is provided with radio buttons to select whether to display the estimated operation quantity 31e and the actual operation quantity 31g in the operation quantity display box 54 (estimated and actual display) or to display the actual operation quantity 31g for each component selected in the display component selection box 51 (component-specific display). In this example, "estimated and actual display" is selected.

[0065] A bar graph is displayed in the operation volume display box 54. In this bar graph, for each type of component supply equipment 12 (component) (8mm single column, 8mm double column, 16mm, etc.), the estimated operation volume 31e (estimated) and the actual operation volume 31g (actual) are stacked and normalized for a period of one week for each area where components are present.

[0066] Specifically, for each type of component, the following timeframes are displayed: production time ΔT4 (production) in production area A1, preparation time ΔT14 (preparation) in preparation area A3, setting time ΔT2 (setting) in setting area A2, maintenance time ΔT12 (maintenance) in maintenance area A4, and storage time ΔT10 (storage) in storage area A5. The actual operation quantity 31g also displays production waiting times ΔT3 and ΔT15 (production), preparation waiting time ΔT13 (preparation), and setting waiting times ΔT2 and ΔT5 (setting). The types of component supply equipment 12 to be displayed can be scrolled using the arrow button 55.

[0067] In this manner, display unit 38 compares and displays the estimated operation quantity 31e and actual operation quantity 31g (operation quantity display box 54) of the components for producing mounting plates within a predetermined period (e.g., one week) according to the production plan. Display unit 38 displays the actual operation quantity 31g separately for operation (production time ΔT4, preparation time ΔT14, setup time ΔT2, and maintenance time ΔT12) and non-operation (production waiting time ΔT3 and ΔT15, preparation waiting time ΔT13, and setup waiting time ΔT2 and ΔT5). By displaying the estimated and actual values ​​of the operation quantity separately for operation and non-operation, the removable components (carriage 5, component supply device 12, mounting head 15, and retaining part 16) used in component mounting equipment M2 to M5 can be appropriately monitored.

[0068] Next, we will refer to Figure 6 An example is described in which the component operation quantity display screen 56 is displayed on the display unit 38 by the display processing unit 36. Figure 6 This is a diagram illustrating an example of a component operation quantity display screen 56 displayed on a display unit 38 provided in a management computer 3 (production management equipment) according to an embodiment of the present disclosure. In this example, "Component Supply Equipment" is selected in the component selection box 51, "Operation Time Display" is selected in the item selection box 52, and "Display for Component" is selected in the content selection box 53.

[0069] In the operation quantity display box 57, for each component supply device 12 (each component), the actual operation time (actual operation quantity 31g) of the component supply device 12 selected in the display component selection box 51 within a day (predetermined time period) is sorted and displayed. The shading line attached to the actual operation time of each component indicates the board type difference of the mounting plate. That is, components with the same shading line indicate that these components are used to produce mounting plates of the same board type.

[0070] In this way, the display unit 38 displays the actual operation amount 31g (operation amount display box 57) for a predetermined period of time (e.g., one day) for each component and each type of mounting plate. By displaying the actual value of the operation amount for each component and each type of mounting plate, the removable components (carriage 5, component supply device 12, mounting head 15, and retaining part 16) used in the component mounting equipment M2 to M5 can be properly monitored.

[0071] Next, we will follow Figure 7 The process describes a production management method (production management procedure) in which the estimated operation amount 31e and actual operation amount 31g of components (carriage 5, component supply equipment 12, mounting head 15 and holding part 16) installed to and removed from component installation equipment M2 to M5 are compared and displayed on a display unit. Figure 7 This is a flowchart illustrating a production management method according to an embodiment of the present disclosure. Hereinafter, the description will be based on the premise that the performance information 31f of the assembly boards produced according to the production plan in the component assembly lines L1 to L2 is collected by the collection unit 33 and stored in the management storage unit 31 of the management computer 3 (production management equipment).

[0072] First, the estimation unit 32 estimates the estimated operation quantity 31e of each component when the mounting plate is produced according to the production plan, based on the production plan information 31a, mounting plate information 31b, component information 31c, and maintenance information 31d (ST1: Operation Quantity Estimation Step). The acquisition unit 34 acquires the actual operation quantity 31g of the component for which the mounting plate is produced according to the production plan from the performance information 31g (ST2: Performance Acquisition Step).

[0073] exist Figure 7 Next, the calculation unit 35 calculates various waiting times (waiting time information 31h) during the period when the component is not operated based on the acquired actual operation quantity 31g (ST3: waiting time calculation step). Next, the display processing unit 36 ​​compares the estimated operation quantity 31e and the actual operation quantity 31g, and displays the estimated operation quantity 31e and the actual operation quantity 31g on the display unit 38 (ST4: display step). Figure 5 Alternatively, in the display step (ST4), the display processing unit 36 ​​causes the display unit 38 to display the actual operation amount 31g within a predetermined time period for each component. Figure 6 Accordingly, the detachable components (carriage 5, component supply device 12, mounting head 15, and retaining part 16) used in the component mounting equipment M2 to M5 can be appropriately controlled.

[0074] As described above, the management computer 3 according to this embodiment is a production management device, which includes: an estimation unit 32, which estimates the estimated operation amount 31e of each component when producing a mounting plate according to the production plan, based on information (component information 31c) about components (carrier 5, component supply device 12, mounting head 15, and holding part 16) installed to and removed from the component mounting devices M2 to M5 and information (production plan information 31a) about the production plan for producing mounting plates; an acquisition unit 34, which acquires the actual operation amount 31g of the component for producing mounting plates according to the production plan; and a display unit 38, which compares and displays the estimated operation amount 31e and the actual operation amount 31g. Accordingly, the removable components used in the component mounting devices M2 to M5 can be appropriately grasped.
