[0001] The present disclosure relates to a task unit management system, a task unit management device, a task unit management method, and a management program.

[0002] Conventionally, in component mounting devices that mount components on boards, operability is maintained by maintaining operational units such as a mounting head and a component supply device that are equipped in the component mounting device. The component mounting device checks the status of the operational unit using various sensors, and if the status of the operational unit deteriorates, maintenance of the operational unit is performed. For this reason, the component mounting device is required to be able to easily check the status of the operational unit after maintenance has been performed.

[0003] As an example of such a work unit management system, Patent Document 1 discloses an electronic component mounting device that, when an abnormality occurs in a component supply unit or suction nozzle, narrows down the cause of the abnormality and notifies the operator of appropriate maintenance work.

[0004] Japanese Patent Application Laid-Open No. 2008-300701

[0005] However, the technology disclosed in Patent Document 1 does not display the state of the work unit after maintenance, making it difficult to easily determine whether the state has improved.

[0006] Therefore, the present disclosure provides a work unit management system that allows a user to easily understand the state of a work unit after maintenance.

[0007] A work unit management system according to one aspect of the present disclosure is a work unit management system that manages multiple work units owned by a production device that produces a product, and is equipped with a status determination unit that determines the status of the multiple work units based on measurement information obtained by measuring the status of the multiple work units owned by the production device, and a display unit that displays a status determination result indicating the determined status of the multiple work units and a status confirmation button for the work units, wherein the status determination unit updates the status determination result by determining the status of the work units in accordance with input to the status confirmation button, and the display unit displays the updated status determination result.

[0008] In addition, a work unit management device according to one aspect of the present disclosure is a work unit management device that manages multiple work units owned by a production device that produces a product, and is equipped with a state determination unit that determines the state of the multiple work units based on measurement information obtained by measuring the state of the multiple work units owned by the production device, and a display unit that displays a state determination result indicating the determined state of the multiple work units and a state confirmation button for the work units, wherein the state determination unit updates the state determination result by determining the state of the work unit in accordance with input to the state confirmation button, and the display unit displays the updated state determination result.

[0009] In addition, a work unit management method according to one aspect of the present disclosure is a work unit management method for managing multiple work units owned by a production device that produces a product, in which the states of the multiple work units owned by the production device are determined based on measurement information obtained by measuring the states of the multiple work units owned by the production device, and a display unit displays a state determination result indicating the determined states of the multiple work units and a state confirmation button for the work units, and the state determination result is updated by determining the state of the work unit in accordance with input to the state confirmation button, and the display unit displays the updated state determination result.

[0010] Furthermore, a management program according to one aspect of the present disclosure is a program for causing a computer to execute a task unit management method.

[0011] These comprehensive or specific aspects may be realized as a system, a method, an integrated circuit, a computer program, or a computer-readable recording medium such as a CD-ROM, or may be realized as any combination of a system, a method, an integrated circuit, a computer program, and a recording medium. The recording medium may also be a non-transitory recording medium.

[0012] According to the work unit management system and the like of the present disclosure, the user can easily grasp the state of the work unit after maintenance.

[0013] Further advantages and effects of one aspect of the present disclosure will become apparent from the specification and drawings.

[0015] Hereinafter, the embodiments will be specifically described with reference to the drawings.

[0016] The embodiments described below are all comprehensive or specific examples. The numerical values, shapes, materials, components, component placement and connection configurations, steps, and step order shown in the following embodiments are merely examples and are not intended to limit the present disclosure. Furthermore, among the components in the following embodiments, components not described in independent claims are described as optional components.

[0017] In addition, each drawing is a schematic diagram and is not necessarily an exact illustration. In addition, the same components are denoted by the same reference numerals in each drawing.

[0018] (Embodiment) <Functional Configuration: Management System 10> First, a task unit management system 1 equipped with a management system 10 according to this embodiment will be described with reference to FIGS. 1 to 3. FIG.

[0019] Fig. 1 is a schematic diagram showing a task unit management system 1 according to an embodiment. Fig. 2 is a block diagram showing the task unit management system 1 of Fig. 1. Fig. 3 is a plan view showing production devices M1 to M9, which are component mounting devices.

[0020] 1 and 2, the operation unit management system 1 is a system for producing a product. For example, the product may be a mounted circuit board with components mounted on a substrate 13, a semiconductor, or food. The operation unit management system 1 includes a production line L and a management system 10.

[0021] The production line L is a production line for producing a product. For example, if the product is a mounting board, the production line L is a component mounting line for mounting components on the board 13. The production line L is equipped with a plurality of production devices M1 to M9.

[0022] Each of the multiple production devices M1 to M9 is a production device for producing a product. The product is produced through multiple processes performed by the multiple production devices M1 to M9. For example, if the product is a mounted board, production device M1 is a loader that supplies boards 13 to production line L, and production device M2 is a printing device that prints solder on boards 13. Also, for example, if the product is a mounted board, each of the multiple production devices M3 to M7 is a component mounting device that mounts components on boards 13, production device M8 is a reflow oven that melts the solder printed on boards 13, and production device M9 is a loader that ejects the mounted boards from production line L.

[0023] For example, the task unit management system 1 may include only one production device instead of multiple production devices. Therefore, the production devices M1 to M9 are merely examples.

[0024] Each of the multiple production machines M1 to M9 has multiple operation units. The multiple operation units include different types of operation units. For example, as shown in FIG. 3, the operation unit may be at least one of a mounting head 18 that moves components and mounts them on a board 13, a nozzle 19a that holds the components, and a feeder 14a that supplies the components. Therefore, each of the multiple production machines M3 to M7 may simply have multiple operation units. The nozzle 19a is an example of a holder.

[0025] Furthermore, among the multiple production devices M1 to M9, each of production devices M3 to M7 has multiple areas E where work is performed on workpieces (work targets). For example, each of production devices M3 to M7 has the function of mounting components onto boards 13 in multiple areas E. A board transport mechanism 12 is installed in the X direction at the center of a base 11 of each of production devices M3 to M7. The board transport mechanism 12 transports boards 13 carried in from the upstream side in the X direction and positions and holds them at a mounting work position by a mounting head 18. The board transport mechanism 12 also carries boards 13 downstream after component mounting work has been completed. Component supply devices 14 are installed on both sides of the board transport mechanism 12. A Y-axis table 15 equipped with a linear drive mechanism is disposed on both ends of the top surface of the base 11 in the X direction. A beam 17 similarly equipped with a linear mechanism is connected to the Y-axis table 15 so as to be freely movable in the Y direction. A mounting head 18 is attached to the beam 17 so as to be freely movable in the X direction. The mounting head 18 is provided with a plurality of nozzle units 19. The Y-axis table 15 and the beam 17 constitute a mounting head moving mechanism that moves the mounting head 18 in horizontal directions (X and Y directions). The mounting head moving mechanism and the mounting head 18 pick up components by suction with the nozzles 19a of the nozzle units 19 from the component removal position of the feeder 14a attached to the component supply device 14. The mounting head moving mechanism then transports the mounting head 18 to a mounting position on the board 13 held by the board transport mechanism 12, where it performs component mounting work.

[0026] 1, the management system 10 is a device that manages the maintenance of each of a plurality of production machines M1 to M9. The management system 10 monitors each of the plurality of production machines M1 to M9 that are operating automatically in real time.

[0027] For example, the management system 10 monitors each of the multiple production equipment M1 to M9 in real time by acquiring measurement information that measures the status of each of the multiple production equipment M1 to M9. The management system 10 manages the maintenance of the production equipment based on the acquired measurement information. Note that, for example, the management system 10 may manage the maintenance of at least one of the multiple production equipment M1 to M9, rather than all of the multiple production equipment M1 to M9.

[0028] Next, the functional configuration of the production equipment M3 to M7 will be described.

[0029] 1 and 2, each of the production devices M3 to M7 has an acquisition unit 21, a state determination unit 22, and a control unit 23. The acquisition unit 21, the state determination unit 22, and the control unit 23 are realized by a processor or the like, and perform various processes.

[0030] The acquisition unit 21 acquires measurement information indicating the status of each of the multiple task units owned by each of the multiple production equipment M3 to M7 from each of the multiple production equipment M3 to M7. The acquisition unit 21 may also be mounted on the production equipment M1, M2, M8, and M9. In this case, the acquisition unit 21 may acquire measurement information indicating the status of each of the multiple task units owned by the production equipment M1, M2, M8, and M9.

[0031] The acquisition unit 21 may acquire measurement information indicating the states of the multiple task units from at least one of the multiple production devices M3 to M7, rather than from all of the multiple production devices M3 to M7. The acquisition unit 21 may also acquire measurement information from at least one of the multiple task units. For example, the measurement information may be an image captured by a camera or the like and / or a detection result by a sensor.

[0032] Measurement information is information indicating the status of the operational units. For example, the measurement information indicating the status of the multiple operational units in each of the production machines M3 to M7 includes information indicating the status of one or more components that make up the multiple operational units in each of the production machines M3 to M7. Specifically, as shown in FIGS. 2 and 3 , the measurement information indicating the status of the operational units in each of the production machines M3 to M7 includes at least information indicating measurements of the air flowing within the mounting head 18, information indicating the sliding load value of the sliding portion 19b that slides the nozzle holder together with the nozzle 19a, information indicating measurements of the air flowing within the nozzle 19a, information showing an image of the tip of the nozzle 19a, and information regarding the component feeding accuracy of the component supply device 14. For example, the status of the operational units can be determined based on the measurement information, such as the deterioration state, wear state, contamination state, and misalignment state of one or more components that make up the operational units in each of the production machines M3 to M7. For example, the one or more components include the mounting head 18, the nozzle 19a, and the feeder 14a. The same may be true for measurement information indicating the status of the task units in the production machines M1, M2, M8, and M9.

[0033] The status determination unit 22 determines the status of each of the multiple operation units on each of the multiple production equipment M3 to M7 based on each of the multiple pieces of measurement information acquired by the acquisition unit 21. The status of the multiple operation units includes multiple different types of status. By determining the status of each of the multiple operation units, the status determination unit 22 outputs a status determination result indicating whether each of the multiple operation units is a maintenance target. In other words, the status determination unit 22 determines the status of each operation unit on each of the production equipment M3 to M7 based on the measurement information indicating the status of the operation unit on each of the production equipment M3 to M7, and outputs a status determination result indicating whether the operation unit on each of the production equipment M3 to M7 is a maintenance target.

[0034] In addition, the status determination unit 22 may determine the status of each of the work units of the production equipment M1, M2, M8, and M9 based on measurement information indicating the status of the work units of the production equipment M1, and output a status determination result indicating whether or not the work units of each of the production equipment M1, M2, M8, and M9 are subject to maintenance.

[0035] The status determination result indicates the status of the work unit and includes at least a normal status, an abnormal status, a maintenance recommended status, and a maintenance warning status. In this embodiment, the status determination result may further include an unmeasured status. For example, a normal status is a status in which the status of the work unit is within the normal specification range. An abnormal status is a status in which the status of the work unit is outside the normal specification range. A maintenance recommended status indicates a status in which the status is within the normal specification range and the threshold for maintenance has been reached (hereinafter, this may be referred to as a quasi-normal status). A maintenance warning status indicates a status in which the status is within the normal specification range and the maintenance warning threshold has been reached. The unmeasured status indicates the initial status or the status when the maintenance registration button on the management system 10 is pressed.

[0036] For example, the state determination unit 22 determines the state of each of the operation units of the production devices M3 to M7 based on measurement information indicating the state of each operation unit of the production devices M3 to M7, and outputs a state determination result indicating whether or not there is a location requiring maintenance in each operation unit of the production devices M3 to M7 (whether or not each operation unit of the production devices M3 to M7 is subject to maintenance). As an example, the state determination unit 22 determines the state of contamination, etc. of the feeder 14a of each of the production devices M3 to M7 from the brightness value of the feeder 14a in an image capturing the exposed sprocket tip and tape pocket position of the feeder 14a of each of the production devices M3 to M7, and if the feeder 14a of each of the production devices M3 to M7 is in a state that is so dirty that cleaning is required, the state determination unit 22 outputs a state determination result indicating that the feeder 14a of each of the production devices M3 to M7 is subject to maintenance. Furthermore, for example, the state determination unit 22 determines the sliding state of the nozzle 19a in each of the production devices M3 to M7 from the detection results of a pressure sensor for detecting the sliding state of the nozzle 19a in each of the production devices M3 to M7, and if the nozzle 19a in each of the work units of the production devices M3 to M7 has become so difficult to slide that cleaning is necessary, it outputs a state determination result indicating that the nozzle 19a in each of the work units of the production devices M3 to M7 is to be subjected to maintenance.

[0037] Similarly, the state determination unit 22 may determine whether or not there is a location requiring maintenance for each of the task units of the production equipment M1, M2, M8, and M9, and output the state determination results.

[0038] For example, the state determination unit 22 stores the state determination results for one or more components that make up the task unit in each of the production machines M3 to M7 in the storage unit 31. Similarly, the state determination unit 22 may store the state determination results for one or more components in the storage unit 31 for the task unit in each of the production machines M1, M2, M8, and M9.

[0039] In addition, the state of the task unit may be further determined. In this case, when a state check button that allows further determination of the state of the task unit is operated, the state determination unit 22 further determines the state of the task unit. In other words, the state determination unit 22 updates the state determination result by further determining the state of the task unit in accordance with input to the state check button. When the state determination result is updated by the state determination unit 22, the state determination unit 22 outputs the updated state determination result to the display unit 42. As a result, the display unit 42 displays the updated state determination result. Furthermore, the state determination unit 22 outputs the updated state determination result to the memory unit 31. As a result, the memory unit 31 stores the updated state determination result.

[0040] The status check button may be a button displayed on the display unit 42 or may be the input unit 41. The input unit 41 may be a button displayed on the display unit 42.

[0041] The control unit 23 calculates the maintenance interval date and time for performing maintenance on the maintenance target based on the past maintenance implementation dates stored in the storage unit 31. The control unit 23 stores the calculated maintenance interval date and time in the storage unit 31. The maintenance interval date and time is, for example, the operating period of the work units of the production equipment M3 to M7 calculated by the control unit 23 in order to perform maintenance on the work units of the production equipment M3 to M7.

[0042] Specifically, the control unit 23 acquires from the storage unit 31 multiple maintenance implementation dates that have been performed in the past for one or more components that make up the task unit in the production equipment M3 to M7 (such as the mounting head 18, the nozzle 19a, and the feeder 14a). The control unit 23 calculates the maintenance interval date and time for each of the one or more components that make up the task unit in the production equipment M3 to M7 from the multiple acquired past maintenance implementation dates. Note that the control unit 23 may calculate the maintenance interval date and time for each of the one or more components that make up the task unit in the production equipment M3 to M7 by increasing or decreasing a predetermined period based on a predetermined period and the acquired multiple past maintenance implementation dates.

[0043] The control unit 23 stores the calculated maintenance interval date and time in the storage unit 31 for each of one or more components that make up the task unit in the production equipment M3 to M7.

[0044] In addition, the control unit 23 may similarly calculate the maintenance interval date and time for each work unit of production equipment M1, production equipment M2, production equipment M8, and production equipment M9, and store the calculated maintenance interval date and time in the memory unit 31.

[0045] Furthermore, the control unit 23 calculates the number of maintenance intervals required to perform maintenance on the maintenance target based on the number of times that the operation units of the production equipment M3 to M7 have operated in the past, which is stored in the memory unit 31. The control unit 23 stores the calculated number of maintenance intervals in the memory unit 31. The number of maintenance intervals is, for example, the number of times that the operation units of the production equipment M3 to M7 have operated, calculated by the control unit 23, in order to perform maintenance on the operation units of the production equipment M3 to M7. For example, the number of maintenance intervals is the number of times that the operation unit has operated in the period (operation period) between one maintenance implementation time and the next maintenance implementation time, among multiple maintenance implementation times at which maintenance was performed in the past.

[0046] Specifically, the control unit 23 acquires from the storage unit 31 the number of maintenance intervals performed in the past for one or more components (such as the mounting head 18, the nozzle 19a, and the feeder 14a) that make up the operation unit in the production equipment M3 to M7. For example, the control unit 23 acquires from the storage unit 31 the number of maintenance intervals for each of multiple past operating periods. The control unit 23 calculates the number of maintenance intervals for each of the one or more components that make up the operation unit in the production equipment M3 to M7 from the acquired number of past maintenance intervals. Note that the control unit 23 may calculate the number of maintenance intervals for each of the one or more components that make up the operation unit in the production equipment M3 to M7 by increasing or decreasing a predetermined number based on a predetermined number and the acquired number of operations for each of multiple past operating periods.

[0047] The control unit 23 stores the calculated maintenance interval number in the storage unit 31 for each of one or more components that make up the task units in the production machines M3 to M7.

[0048] The control unit 23 may also store in the storage unit 31 the calculated maintenance interval numbers for each of the task units of the production equipment M1, production equipment M2, production equipment M8, and production equipment M9.

[0049] The control unit 23 also calculates the variances in multiple maintenance interval dates and times and multiple maintenance interval counts. Specifically, the control unit 23 calculates and compares the variances in multiple maintenance dates and times performed in the past for the work units of the production equipment M3 to M7 with the variances in multiple maintenance interval counts performed in the past. The control unit 23 outputs the maintenance date and time with the least variance as a result of the comparison to the display unit 42. The control unit 23 stores the maintenance date and time with the least variance in the work units of the production equipment M3 to M7 in the memory unit 31 as the predicted maintenance date and time.

[0050] Similarly, the control unit 23 may output the maintenance date and time with less variation to the display unit 42 for each work unit of production equipment M1, production equipment M2, production equipment M8, and production equipment M9, or may store the maintenance date and time with less variation in the memory unit 31 as the predicted maintenance date and time.

[0051] The control unit 23 predicts the first next maintenance date and time based on the past maintenance interval dates and times for the task units of each of the production equipment M3 to M7 stored in the memory unit 31. The control unit 23 also predicts the second next maintenance date and time based on the past maintenance interval count for the task units of each of the production equipment M3 to M7 stored in the memory unit 31. Furthermore, if the task unit has multiple maintenance targets, the control unit 23 predicts the first next maintenance date and time for each maintenance target, i.e., for each of the multiple task units, based on the maintenance interval date and time, and the second next maintenance date and time based on the maintenance interval count. The control unit 23 stores the first next maintenance date and time and the second next maintenance date and time predicted for each of the one or more components that make up the task unit of each of the production equipment M3 to M7 in the memory unit 31.

[0052] In addition, the control unit 23 may also store the predicted first next maintenance date and time and second next maintenance date and time in the memory unit 31 for each work unit of production equipment M1, production equipment M2, production equipment M8, and production equipment M9.

[0053] The control unit 23 also stores the predicted maintenance dates and times that have been predicted in the past for each of the work units of the production equipment M3 to M7 in the storage unit 31. Therefore, the control unit 23 may predict the first next maintenance date and time and the second next maintenance date and time for each of the work units of the production equipment M3 to M7 by taking into account the predicted maintenance dates and times in the past.

[0054] Furthermore, control unit 23 transitions between a first screen displayed by display unit 42 and a second screen different from the first screen. Specifically, when input unit 41 accepts an input from the user, control unit 23 transitions the content displayed on display unit 42 from the first screen to the second screen, or transitions the content displayed on display unit 42 from the second screen to the first screen. The first screen can be referred to as a first image, and the second screen can be referred to as a second image.

[0055] Next, the functional configuration of the management system 10 will be described.

[0056] The management system 10 includes a storage unit 31, an input unit 41, and a display unit 42. The management system 10 may include only the input unit 41 and the display unit 42, and the other components are not essential components. The input unit 41 and the display unit 42 may be provided in the production devices M1 to M9.

[0057] The storage unit 31 stores various information as described above. For example, the storage unit 31 stores measurement information, status determination results, updated status determination results, past maintenance implementation times, maintenance interval dates and times, the number of maintenance intervals, predicted maintenance dates and times, the first next maintenance date and time, and the second next maintenance date and time, etc. For example, the storage unit 31 is realized by a memory or the like.

[0058] The input unit 41 accepts input from the user. For example, the input unit 41 accepts input from the user to set multiple maintenance dates and times and multiple maintenance deadlines. For example, the input unit 41 is realized by a touch panel, hardware buttons, or the like.

[0059] The display unit 42 displays the status determination result, which is the result determined by the status determination unit 22 and indicates the status of at least one of the multiple statuses of the production machines M1 to M9. When the status determination result is updated, the display unit 42 also displays the updated status determination result. The display unit 42 may be implemented, for example, by a liquid crystal panel or an organic EL panel.

[0060] The display unit 42 can also display at least one of the status determination results determined for each of the multiple different types of work units. The display unit 42 can also display the status determination results for each of the multiple areas E where work is performed on each of the production devices M1 to M9. The display unit 42 can also display a first screen showing the status determination results indicating the status of at least one of the multiple work units, and a second screen showing the status determination results for all of the multiple work units. The display unit 42 also displays updated status determination results in a similar manner. The display unit 42 also displays at least one of the first next maintenance date and time and the second next maintenance date and time. For example, the display unit 42 displays at least one of the first next maintenance date and time and the second next maintenance date and time for at least one work unit. The display unit 42 also displays the first next maintenance date and time or the second next maintenance date and time, whichever corresponds to the least variation, of the multiple maintenance interval dates and times and the multiple maintenance interval counts.

[0061] As described above, maintenance is performed on the operation units of each of the production devices M3 to M7. At this time, the display unit 42 displays information indicating the operation units, a selection button (icon), a status check button (icon), and a status check selection button (icon). The information indicating the operation units is information based on the installation positions of multiple operation units owned by a certain production device, i.e., information indicating the location of the operation unit. The selection button indicates the location of the operation unit and is a button for selecting the target operation unit from the multiple operation units for maintenance. The status check button is a button for checking the status of the operation unit. The status check selection button is a button for selecting the operation unit for which status check is to be performed from the multiple operation units.

[0062] <Monitoring List of Operational Units> First, the monitoring list used by the status determination unit 22 to determine the status of the multiple operational units in the production equipment M3 to M7 will be described with reference to FIG.

[0063] FIG. 4 is a diagram showing a monitoring list of task units.

[0064] As shown in Fig. 4, the status determination unit 22 determines the status of multiple operation units on production equipment M3 to M7 out of production equipment M1 to M9 based on the monitoring list. The monitoring list is made up of monitoring units that monitor the components of the operation units, namely the mounting head 18, nozzle 19a, and feeder 14a, as well as monitoring items corresponding to each monitoring unit and details corresponding to the monitoring items. Note that in Fig. 4 and subsequent figures, the mounting head 18 may be simply referred to as the head.

[0065] For example, the state determination unit 22 determines the state of each monitoring unit that is a component of a plurality of task units in the production equipment M3 to M7 based on the monitoring unit, monitoring item, and description.

[0066] Specifically, FIG. 4 illustrates a mounting head 18, a nozzle 19a, and a feeder 14a as examples of monitoring units. When the monitoring unit is the mounting head 18, the monitored items are filter clogging and nozzle holder sliding. In the description, it is indicated that filter clogging is determined by measuring the flow rate of the mounting head 18 at a predetermined timing during the component mounting operation of the mounting head 18. In the description, it is indicated that nozzle holder sliding is determined by measuring the sliding load of the holder. When the monitoring unit is the nozzle 19a, the monitored items are nozzle clogging and nozzle tip status. In the description, it is indicated that nozzle clogging is determined by measuring the flow rate of the nozzle 19a at a predetermined timing during the component suction operation of the nozzle 19a. In the description, it is indicated that the nozzle tip status is determined by acquiring an image of the nozzle tip at a timing for measuring changes over time. When the monitoring unit is the feeder 14a, the monitored item is feeder feed accuracy. In the description, it is indicated that feeder feed accuracy is determined by estimating the tape pocket position at a timing when the sprocket makes one revolution.

[0067] In this way, the status determination unit 22 determines the status of the monitoring unit, that is, the status of the multiple work units in the production devices M3 to M7, and outputs the status determination result. The status determination unit 22 stores the status determination result by outputting it to the storage unit 31. The status determination unit 22 also outputs the status determination result to the display unit 42, causing the display unit 42 to display the status determination result.

[0068] Next, a status list for displaying the status determination results obtained by the display unit 42 for determining the statuses of the multiple task units in the production equipment M3 to M7 will be described with reference to FIG.

[0069] FIG. 5 shows a list of task unit states.

[0070] 5, the display unit 42 displays a state determination result indicating the state of at least one of the states of the multiple task units. That is, the display unit 42 displays the state determination result determined by the state determination unit 22. In this case, the display unit 42 displays the state determination result in different colors.

[0071] Specifically, the status list in Figure 5 is composed of the status of the task unit, display content indicating the status of the task unit, a color indicating the status of the task unit, and an explanation of the color indicating the status of the task unit.

[0072] The status of the operation unit is configured as a plurality of different statuses, such as an "unmeasured" status, a "normal" status, a "semi-normal" status, a "maintenance warning" status, and an "abnormal" status. The display content is configured as a plurality of different content, such as "unmeasured," "normal," "semi-normal," "warning," and "abnormal." The colors are configured as a plurality of different colors, such as a solid color, green (thin diagonal hatching), yellow-green (checkered hatching), yellow (thick diagonal hatching), and red (dotted hatching). Here, the "normal" status indicates a status in which maintenance is not required. The "semi-normal" status indicates a status in which maintenance is due, but there is still ample time in the schedule. The "warning" status indicates a status in which maintenance is due later in the maintenance schedule, but the impact on product quality is small. The "abnormal" status indicates a status in which the impact on product quality is significant, and the operation unit is stopped.

[0073] For example, if the status and display content of the task unit is "not measured," the color corresponds to a solid color. As an explanation of the color, a solid color indicates the initial state or the state when the maintenance registration button is pressed.

[0074] Furthermore, when the status and display content of a task unit are "normal," the color corresponds to green. As an explanation of the color, green indicates that the status is within the normal specifications.

[0075] Furthermore, when the status and display content of the operation unit are "quasi-normal," the color corresponds to yellow-green. As an explanation of the color, yellow-green indicates a state where the unit is within the normal specification range and has reached the threshold for maintenance.

[0076] Furthermore, when the status of the task unit is "Maintenance Warning" and the display content is "Warning," the color corresponds to yellow. As for the color explanation, yellow indicates a state where the task is within the normal specification range and has reached the maintenance warning threshold.

[0077] Furthermore, if the status and display content of a task unit is "abnormal," the color corresponds to red. As an explanation of the color, red indicates a state that is outside the range of normal specifications.

[0078] In Figure 5 and other figures, the status of a task unit is indicated by color, but this is not limited to this. For example, the status of a task unit may be indicated by symbols such as circle, triangle, and square. The status of a task unit may also be indicated by letters such as A, B, and C.

[0079] <Status Determination Result Screens> Next, the status confirmation screen, head inspection screen, nozzle inspection screen, and feeder inspection screen, which are the status determination results obtained by the display unit 42 determining the status of multiple work units in production devices M3 to M7, will be described with reference to FIGS. 6 to 9.

[0080] Fig. 6 is a diagram showing a status confirmation screen showing the status determination results. Fig. 7 is a diagram showing a head inspection screen showing the status determination results. Fig. 8 is a diagram showing a nozzle inspection screen showing the status determination results. Fig. 9 is a diagram showing a feeder inspection screen showing the status determination results.

[0081] For example, as shown in FIG. 6 , the display unit 42 displays a status check screen (or status check image) that extracts the status determination results of the work unit. The status check screen displays multiple tabs (or icons). One of the multiple tabs includes an item called "Maintenance - Status Inspection" for maintaining the work unit. The "Maintenance - Status Inspection" status check screen displays the status determination results for each of multiple areas E. The status check screen in FIG. 6 illustrates the status determination results for each of four areas E: "AR," "AF," "BR," and "BF." The four areas E are a collective term for "AR," "AF," "BR," and "BF." Note that FIG. 3 illustrates only two of the four areas E.

[0082] The status determination results show examples of "target units" as working units and "statuses" corresponding to the "target units." Examples of "target units" in the four areas E include a "16-nozzle head" icon, a "nozzle" icon, and a "feeder" icon. Examples of "statuses" in "AR" include a yellow-green icon corresponding to the "16-nozzle head" icon indicating "near-normal," a yellow icon corresponding to the "nozzle" icon indicating "warning," and a red icon corresponding to the "feeder" icon indicating "abnormal." Examples of "statuses" in "AF" include a plain icon corresponding to the "16-nozzle head" icon indicating "not measured," a yellow icon corresponding to the "nozzle" icon indicating "warning," and a red icon corresponding to the "feeder" icon indicating "abnormal." Examples of "statuses" in "BR" include a yellow-green icon corresponding to the "16-nozzle head" icon indicating "near-normal," a yellow icon corresponding to the "nozzle" icon indicating "warning," and a red icon corresponding to the "feeder" icon indicating "abnormal." The "Status" in "BF" is exemplified by a green icon indicating "Normal" corresponding to the "16-nozzle head" icon, a yellow icon indicating "Warning" corresponding to the "Nozzle" icon, and a red icon indicating "Abnormal" corresponding to the "Feeder" icon.

[0083] Furthermore, the status confirmation screen shows the status of multiple work units using colored icons. For example, if the work unit is a "16-nozzle head," the icon shown will be the color corresponding to the nozzle 19a in the worst condition out of the 16 nozzles 19a.

[0084] Next, when the user selects, for example, the "16-nozzle head" of "BR" on the status check screen shown in FIG. 7, the display unit 42 displays the head inspection screen (head inspection image) shown in FIG. 7. For example, the display unit 42 can transition between a first screen and a second screen. That is, the display unit 42 can transition between the status check screen shown in FIG. 6 and the head inspection screen shown in FIG. 7. When the status check screen is an example of the first screen, the head inspection screen is an example of the second screen. Also, when the head inspection screen is an example of the first screen, the status check screen is an example of the second screen.

[0085] On the head inspection screen, the display unit 42 displays the states of the multiple nozzles 19a as colored icons as the states of the work units.

[0086] The display unit 42 is also located in the center of the head inspection screen and displays information indicating the operation unit. For example, on the head inspection screen, the display unit 42 displays buttons (icons) labeled POS XX, each representing the installation position of a plurality of nozzles 19a. XX is an arbitrary number. For example, Figure 7 shows buttons POS1 to POS16 indicating the installation positions of 16 nozzles 19a, and icons located adjacent to each button that indicate the status of the nozzles 19a using colors.

[0087] The display unit 42 may further display selection buttons in the information indicating the work unit displayed by the display unit 42. For example, in FIG. 7 , among POS1 to POS16 indicating the installation positions of the 16 nozzles 19a, POS5 to POS7 and POS12 to POS14, indicated by hatching with dots, indicate that the work unit is in a "quasi-normal" state, a "maintenance warning" state, or an "abnormal" state. Nozzles 19a in these states require maintenance. Therefore, as indicated by the hatching with dots, the display unit 42 displays POS5 to POS7 and POS12 to POS14 in different colors as selection buttons for selecting maintenance. Furthermore, POS4, POS11, and POS16 indicate that the work unit is in a "normal" state, so maintenance is not required. In this case, the display unit 42 does not display POS4, POS11, and POS16 as selection buttons.

[0088] The display unit 42 may also display a status check button for the operation unit on the head inspection screen. The status check button is positioned adjacent to the information indicating the operation unit on the head inspection screen. For example, the "maintenance position" indicating POS5 to POS7 and POS12 to POS14 to be maintained is selected, maintenance is performed, and the status determination result as a result of the maintenance being completed by selecting "maintenance complete" is stored in the memory unit 31. Thereafter, when the "status check button" is selected for reasons such as checking whether the maintenance was performed correctly, the display unit 42 displays the status determination result stored in the memory unit 31. Furthermore, when maintenance is performed again, the display unit 42 displays the updated status determination result.

[0089] The display unit 42 may further display a status check selection button on the head inspection screen. The status check selection button is positioned adjacent to the information indicating the operation unit on the head inspection screen and adjacent to the status check button. The status check selection button makes it possible to select multiple operation units for each operation unit status; for example, the display unit 42 extracts and displays only operation unit statuses such as "filter clogged" and "holder sliding" that correspond to "abnormal" or "warning." This makes it possible to select one or more operation units for each operation unit status and perform maintenance.

[0090] Furthermore, on the head inspection screen, "filter clogging" and "holder sliding" are shown as icons as specific states of the plurality of nozzles 19a. The display unit 42 displays on the head inspection screen in a manner that indicates which nozzle 19a among the plurality of nozzles 19a has a clogged filter or a sliding holder.

[0091] For example, in the case of a clogged filter on the head inspection screen of FIG. 7, the state of the nozzle 19a at each of POS1 to POS16 indicating the position of the nozzle 19a is displayed with a colored icon.

[0092] Next, when the user selects, for example, the "BR" "nozzle" indicated by hatching with dots on the status confirmation screen shown in FIG. 6 , the display unit 42 displays the nozzle inspection screen (nozzle inspection image) shown in FIG. 8 . The display unit 42 can transition between the status confirmation screen shown in FIG. 6 and the nozzle inspection screen shown in FIG. 8 . When the status confirmation screen is an example of the first screen, the nozzle inspection screen is an example of the second screen. Also, when the nozzle inspection screen is an example of the first screen, the status confirmation screen is an example of the second screen.

[0093] On the nozzle inspection screen, the status of the multiple nozzles 19a is shown with colored icons as the status of the work unit. Also on the nozzle inspection screen, the changer positions of the multiple nozzles 19a are shown with icons labeled F00. For example, Figure 8 shows icons F11 to F18 and F21 to F28 indicating the changer positions of the nozzles 19a, and icons arranged adjacent to each icon that indicate the status of the nozzles 19a with colors.

[0094] Furthermore, on the nozzle inspection screen, nozzle clogging and tip states are displayed with icons as specific states of the multiple nozzles 19 a. The nozzle inspection screen displays the nozzle clogging and tip states of the nozzles 19 a so that it is clear which nozzles 19 a among the multiple nozzles 19 a are in the nozzle clogging and tip state.

[0095] For example, in the nozzle inspection screen of FIG. 8, in the case of a clogged nozzle, the state of the nozzle 19a at each of F11 to F18 and F21 to F28, which indicate the position of the nozzle 19a, is displayed by an icon indicated by a color.

[0096] Next, when the user selects "Feeder" under "AR" on the status confirmation screen shown in FIG. 6, the display unit 42 displays the feeder inspection screen (feeder inspection image) shown in FIG. 9. The display unit 42 can transition between the status confirmation screen shown in FIG. 6 and the feeder inspection screen shown in FIG. 9. When the status confirmation screen is an example of the first screen, the feeder inspection screen is an example of the second screen. When the feeder inspection screen is an example of the first screen, the status confirmation screen is an example of the second screen.

[0097] On the feeder inspection screen, the status of the multiple feeders 14a is indicated by colored icons as the status of the work unit. Also, on the feeder inspection screen, the multiple feeders 14a are indicated by numbered icons. For example, Fig. 9 shows an example of numbered icons representing 17 feeders 14a and colored icons adjacent to each icon indicating the status of the feeders 14a.

[0098] Furthermore, on the feeder inspection screen, the component feeding accuracy is displayed with an icon as a specific state of the plurality of feeders 14a. On the feeder inspection screen, the component feeding accuracy of each of the plurality of feeders is displayed so that it can be seen.

[0099] For example, on the feeder inspection screen of FIG. 9, the component feeding accuracy of each of the plurality of feeders 14a is displayed by an icon indicated by a different color.

[0100] In this embodiment, the status of the task unit to be maintained can be easily grasped by displaying the status of the task unit in each of the multiple areas E, i.e., the status of one or more components that make up the task unit, as shown in the status confirmation screen in Figure 6. Furthermore, because the status confirmation screen displays the status of the component in the worst condition, it can be easily grasped whether or not the task unit includes a component that is the target of maintenance.

[0101] Furthermore, when the user selects via the input unit 41 the icon for the "16-nozzle head," which is shown as an example of a "target unit" as a work unit on the status check screen, the transition unit 25 transitions from the status check screen to a head inspection screen, and the display unit 42 displays the head inspection screen. This allows the user to understand the status of the mounting head 18, which is the work unit, the timing of maintenance for the mounting head 18, and so on, via the head inspection screen.

[0102] Furthermore, when the user selects the "nozzle" icon, which is exemplified as a "target unit" as a work unit on the status check screen, via the input unit 41, the transition unit 25 transitions from the status check screen to a nozzle inspection screen, and the display unit 42 displays the nozzle inspection screen. This allows the user to understand the state of the nozzle 19a, which is the work unit, the timing of maintenance for the nozzle 19a, etc., via the nozzle inspection screen.

[0103] Furthermore, when the user selects the "feeder" icon, which is exemplified as a "target unit" as a work unit on the status check screen, via the input unit 41, the transition unit 25 transitions from the status check screen to a feeder inspection screen, and the display unit 42 displays the feeder inspection screen. This allows the user to understand the status of the feeder 14a, which is the work unit, the timing of maintenance for the feeder 14a, and the like, via the feeder inspection screen.

[0104] <Maintenance of Mounting Head 18> Next, maintenance of the mounting head 18 in this embodiment will be described with reference to FIGS.

[0105] Fig. 10 is a perspective view of head maintenance device 140 according to the embodiment. Fig. 11 is a perspective view of the main parts of production devices M3 to M7, showing the state in which head maintenance device 140 according to the embodiment is attached to feeder base 122. Fig. 12 is a partially enlarged perspective view of head maintenance device 140 according to the embodiment.

[0106] 10 to 12, the head maintenance device 140 includes a base unit 141 that is attached to a feeder base 122, which is a holder for the part feeder 123, so as to be replaceable with the part feeder 123, and a maintenance execution unit 142 that is provided on the base unit 141 and performs maintenance on the mounting head 18. The maintenance execution unit 142 performs maintenance on the mounting head 18 (more specifically, each shaft member 132 in FIG. 12 ) that has been moved above the maintenance execution unit 142 by the head moving mechanism 124.

[0107] The base portion 141 of the head maintenance device 140 has a horizontal, flat plate shape extending in the Y direction, and its underside has slot insertion portions 141s that extend in the Y direction and have an inverted T-shaped cross section that can be inserted into the feeder base 122. Here, four slot insertion portions 141s are provided on the underside of the base portion 141, lined up in the X direction at intervals that correspond to the intervals between the slots 122a on the feeder base 122. The slot insertion portions 141s are inserted into the slots 122a on the feeder base 122. Here, of the two Y-direction ends of the head maintenance device 140 when attached to the feeder base 122, the end closest to the substrate transport conveyor 121 is referred to as the front end, and the opposite end is referred to as the rear end.

[0108] 10 and 12, the maintenance execution unit 142 of the head maintenance device 140 is provided in an area on the front end side of the base unit 141, and includes a load cell 151, a nozzle holder attachment / detachment block 152, and a shaft cleaner 153. The head maintenance device 140 also includes a control unit 154, and the load cell 151 and the shaft cleaner 153 are each electrically connected to the control unit 154. Signal transmission between the head maintenance device 140 and the management system 110 is also possible.

[0109] The load cell 151 is provided on a pedestal 141a erected at the frontmost part of the base 141, and the nozzle holder 133, from which the nozzle 19a has been removed, is pressed from above by the shaft member 132. The load cell 151 detects the pressing load applied by the shaft member 132 and transmits the detected pressing load to the control unit 154. The nozzle holder 133 may be included in the holding unit.

[0110] The worse the sliding condition of the nozzle holder 133 relative to the shaft member 132, the larger the load value detected by the load cell 151. A first reference load selected as a load threshold is stored in the control unit 154 of the head maintenance device 140, and the control unit 154 determines whether the sliding condition of the nozzle holder 133 relative to the shaft member 132 under the first reference load is good or bad based on whether the pressing load transmitted from the load cell 151 exceeds the first reference load (i.e., based on the detected pressing load). Here, the first reference load is set to a pressing load at which it is expected that the nozzle holder 133 cannot be normally removed from the shaft member 132. The control unit 154 of the head maintenance device 140 also stores a second reference load selected as a threshold load for which use of the shaft member 132 is unsuitable, and the control unit 154 determines whether the sliding state of the nozzle holder 133 relative to the shaft member 132 under the second reference load is good or bad based on whether the pressing load transmitted from the load cell 151 exceeds the second reference load (i.e., based on the detected pressing load). The first reference load and the second reference load may be the same value.

[0111] Nozzle holder attachment / detachment block 152 is made of a block-shaped member attached to the upper surface of block portion 141b that is erected on base portion 141, and nozzle holder attachment / detachment block 152 is provided with a plurality of holder insertion holes 152a into which the lower ends of nozzle holders 133 are inserted. When removing nozzle holder 133 from shaft member 132, shaft member 132 to which nozzle holder 133 to be removed is attached is positioned above holder insertion holes 152a, and then shaft member 132 is lowered to insert nozzle holder 133 into holder insertion holes 152a from above. Then, when the shaft member 132 is rotated in the vertical direction (Z direction), a protrusion (not shown) on the outer peripheral surface of the nozzle holder 133 fits into a locking groove (not shown) formed on the inner side surface of the holder insertion hole 152a, and the engagement between the shaft member 132 and the nozzle holder 133 is released.Therefore, when the shaft member 132 is raised from this state, the nozzle holder 133 is left behind in the holder insertion hole 152a and the nozzle holder 133 is removed from the shaft member 132.

[0112] In this way, the nozzle holder detachment block 152 holds the nozzle holder 133 when the nozzle holder 133 is detached from the shaft member 132 .

[0113] Two shaft cleaners 153 are arranged side by side in the Y direction on the upper surface of the base portion 141c of the base portion 141. Each shaft cleaner 153 has a cylindrical configuration that opens upward, and a friction-receiving portion (not shown) is formed within its internal space 153a. With the shaft member 132 inserted into the internal space 153a of the shaft cleaner 153, the shaft member 132 is repeatedly moved up and down and further repeatedly rotated forward and backward, causing the outer circumferential surface and bottom surface of the shaft member 132 (i.e., the sliding portion between the shaft member 132 and the nozzle holder 133) to rub against the friction-receiving portion. This removes debris adhering to the outer circumferential surface and bottom surface of the shaft member 132. The friction-receiving portion may be made of various materials, such as various fiber materials and resin materials.

[0114] Next, maintenance of the nozzle 19a in this embodiment will be described with reference to Fig. 13. Fig. 13 is a cross-sectional view showing the internal structure of the nozzle 19a according to this embodiment.

[0115] The mounting head 18 is composed of a plurality of shaft member holding portions 131, shaft members 132, nozzle holders 133, sliding portions 19b, compression springs 136, and nozzles 19a. The shaft member holding portion 131 extends downward from the mounting head 18. The shaft member holding portion 131 is provided with a shaft member 132, nozzle holders 133, sliding portions 19b, compression springs 136, and nozzles 19a. The nozzle holders 133 are attached to the sliding portions 19b at the lower end of the shaft member 132. The nozzle holders 133 and the sliding portions 19b are in sliding contact with each other. The nozzle holders 133 can slide vertically relative to the sliding portions 19b.

[0116] Nozzle 19a can be expected to operate normally when nozzle holder 133 can slide smoothly against sliding portion 19b and compression spring 136 can expand and contract smoothly. Only when nozzle 19a is in a state in which it can operate normally can it apply just the right amount of pressing load, and if nozzle holder 133 no longer slides smoothly against shaft member holding portion 131 or compression spring 136 no longer expands and contracts smoothly, an overload exceeding the pressing load will act on nozzle holder 133, or conversely, a situation will occur in which a sufficient pressing load will not act, which will have a significant adverse effect on mounting quality, such as damage to various components, a decrease in the pickup rate, and a decrease in mounting strength.

[0117] To maintain the nozzle 19a in a state in which it can operate normally, it is necessary to slide the sliding portion 19b relative to the nozzle holder 133 and expand and contract the compression spring 136, i.e., to cause the nozzle 19a to perform an expansion and contraction operation. The nozzle 19a attached to the mounting head 18 maintains a normal operating state by repeatedly expanding and contracting each time a mounting operation is performed to pick up a component and mount it on the board 13 shown in Figure 3. However, the replacement nozzles 19a stored in the nozzle stocker may include nozzles that have been used a long time ago and nozzles that have never been used, and such nozzles may be in a state in which they cannot be expected to operate normally.

[0118] When the production devices M3 to M7 resume use of a nozzle 19a immediately after replacement, or a nozzle 19a attached to the mounting head 18 after a mounting operation has been stopped, they perform a dummy preparatory operation prior to the main operation used for actual suction and mounting. The preparatory operation is an operation in which the nozzle 19a is moved back and forth in the vertical direction several times while the suction portion of the nozzle 19a is kept in contact with the nozzle pressing surface.

[0119] <Operational Effects> Next, operational effects of the task unit management system 1, task unit management device, task unit management method, and management program according to the present embodiment will be described.

[0120] As described above, the task unit management system 1 according to Technology 1 of this embodiment is a task unit management system that manages multiple task units owned by production equipment (e.g., M1-M9) that produces a product. It includes a status determination unit 22 that determines the status of the multiple task units based on measurement information obtained by measuring the status of the multiple task units owned by the production equipment, and a display unit 42 that displays status determination results indicating the determined status of the multiple task units and task unit status confirmation buttons. The status determination unit 22 also updates the status determination results by determining the status of the task units in response to input to the status confirmation button. The display unit 42 then displays the updated status determination results.

[0121] This allows the display unit 42 to display status determination results indicating the status of multiple task units. Therefore, the display unit 42 can display, for example, the task unit in the worst status among the statuses of multiple task units as the task unit status. In other words, the display unit 42 can also avoid displaying task units in good status. In this way, the display unit 42 can reduce and display items, thereby improving user visibility.

[0122] Furthermore, if the state of the task unit is further determined, the display unit 42 can display the updated state determination result by the further determination, thereby improving visibility for the user.

[0123] Therefore, according to the operation unit management system 1 of the embodiment, the user can easily grasp the state of the operation unit of the production equipment after maintenance.

[0124] Furthermore, in the task unit management system 1, the state determination unit 22 and the display unit 42 may be mounted on separate, separable devices.

[0125] As described above, the task unit management device according to Technology 10 of this embodiment is a task unit management device that manages multiple task units owned by a production device that produces a product, and includes a status determination unit 22 that determines the status of the multiple task units based on measurement information obtained by measuring the status of the multiple task units owned by the production device, and a display unit 42 that displays status determination results indicating the determined status of the multiple task units and a task unit status confirmation button. The status determination unit 22 also updates the status determination results by determining the status of the task units in response to input to the status confirmation button. The display unit 42 then displays the updated status determination results.

[0126] Therefore, the state determination unit 22 and the display unit 42 may be mounted on a single device as a task unit management device. This task unit management device also provides the same effects as those described above.

[0127] Furthermore, as described above, the work unit management method in technology 11 of this embodiment is a work unit management method for managing multiple work units owned by a production device that produces a product, and includes determining the states of the multiple work units based on measurement information obtained by measuring the states of the multiple work units owned by the production device, displaying on the display unit 42 a state determination result indicating the determined states of the multiple work units and a state confirmation button for the work units, updating the state determination result by determining the state of the work unit in accordance with input to the state confirmation button, and displaying the updated state determination result on the display unit 42.

[0128] This task unit management method also provides the same effects as those described above.

[0129] As described above, the management program in Technique 12 of this embodiment is a program for causing a computer to execute the task unit management method described in Technique 11.

[0130] This management program also provides the same effects as those described above.

[0131] As described above, the task unit management system 1 in Technology 2 of this embodiment is the task unit management system 1 described in Technology 1. In this case, the display unit 42 displays information indicating task units aligned with the attachment positions of the multiple task units.

[0132] This allows the worker to easily grasp the installation positions of multiple work units by looking at the information indicating the displayed work units. In particular, as shown in the head inspection screen of Figure 7, the installation positions of multiple work units can be displayed simultaneously on the display unit 42 on a single screen, allowing the worker to simultaneously grasp information indicating the work units for multiple work units.

[0133] As described above, the task unit management system 1 in Technique 3 of this embodiment is the task unit management system 1 described in Technique 1 or 2. In this case, the display unit 42 further displays a selection button for selecting a target task unit for maintenance from a plurality of task units.

[0134] This allows the display unit 42 to display selection buttons, allowing the worker to easily grasp the work unit to be maintained and easily select the work unit to be maintained.

[0135] In particular, as shown on the head inspection screen in Figure 7, the display unit 42 can simultaneously display information indicating the work unit along with a selection button on a single screen, allowing the worker to easily select multiple work units to be maintained.

[0136] As described above, the task unit management system 1 in Technique 4 of this embodiment is the task unit management system 1 described in any one of Techniques 1 to 3. In this case, the display unit 42 further displays a status check selection button for selecting a task unit for which status check is to be performed from among the multiple task units.

[0137] This allows the display unit 42 to display the status confirmation selection button, enabling the worker to, for example, grasp the status of multiple task units or grasp the status of each task unit for each maintenance target state. This makes it easy for the worker to check the status of the task units.

[0138] In particular, as shown in the head inspection screen in Figure 7, the status confirmation selection button can be displayed on the display unit 42 simultaneously with information indicating the work unit and selection buttons on a single screen, making it easy for the worker to check the status of the work unit.

[0139] As described above, the task unit management system 1 in Technique 5 of this embodiment is the task unit management system 1 described in any one of Techniques 1 to 4. In this case, the production device has multiple areas for producing products. The display unit 42 displays the status determination results for each of the multiple areas.

[0140] According to this, the status determination result for each of the multiple areas E is displayed on the display unit 42, so that the user can recognize the status determination result indicating the status of the task unit for each of the multiple areas E.

[0151] Furthermore, in the above embodiment, the status of multiple operation units in production equipment M3 to M7 is determined. However, the status of the operation unit in the printing equipment, which is production equipment M2, may also be determined. The monitored items for the operation units of the printing equipment include at least one of the following: the flatness of the substrate holder that holds the substrate 13, the start-up time and operation period of the vacuum pump, the movement distance of the moving axis that moves the squeegee, camera contamination, and the discharge volume of the solvent discharge unit. The flatness of the holder that holds the substrate 13 is detected at a predetermined timing, such as when the printing equipment is started, using a height detection sensor provided in the printing equipment. The start-up time of the vacuum pump is detected by detecting the start-up time of the vacuum pump after printing the substrate 13. The operation period of the vacuum pump is monitored while the printing equipment is operating. The movement distance of the moving axis that moves the squeegee is measured by measuring the distance the moving axis moves while the printing equipment is operating. The degree of contamination of the camera is detected by taking a photograph before production begins. The discharge volume of the solvent discharge unit is detected when the mask used for printing is cleaned. Each detection value and time, etc. is set to a value corresponding to either normal, abnormal, maintenance recommended, or maintenance warning, and the status of the work unit can be displayed based on that value.

[0152] Furthermore, the control unit and status determination unit included in the task unit management system and task unit management device according to the above-described embodiment are typically realized as an LSI, which is an integrated circuit. These may be individually implemented as single chips, or some or all of them may be integrated into a single chip.

[0153] Furthermore, the integrated circuit is not limited to an LSI, but may be realized by a dedicated circuit or a general-purpose processor. An FPGA (Field Programmable Gate Array) that can be programmed after the LSI is manufactured, or a reconfigurable processor that can reconfigure the connections and settings of circuit cells within the LSI may also be used.

[0154] In each of the above embodiments, each component may be configured with dedicated hardware, or may be realized by executing a software program suitable for each component. Each component may be realized by a program execution unit such as a CPU or processor reading and executing a software program recorded on a recording medium such as a hard disk or semiconductor memory.

[0155] Furthermore, all of the numbers used above are examples for specifically explaining the present disclosure, and the embodiments of the present disclosure are not limited to the numbers shown as examples.

[0156] The division of functional blocks in the block diagram is an example, and multiple functional blocks may be realized as a single functional block, one functional block may be divided into multiple blocks, or some functions may be moved to another functional block.Furthermore, the functions of multiple functional blocks having similar functions may be processed in parallel or in time-sharing by a single piece of hardware or software.

[0157] In addition, this disclosure also includes forms obtained by making various modifications to the above-mentioned embodiments that a person skilled in the art would think of, and forms realized by arbitrarily combining the components and functions of each embodiment within the scope of this disclosure.
