[0033] (Implementation Method)

[0034] <Functional Structure: Work Unit Management System 10>

[0035] First, the production system 1 equipped with the work unit management system 10 of this embodiment is used. Figures 1 to 3 To explain.

[0036] Figure 1 Schematic diagram showing the work unit management system 10 according to the embodiment. Figure 2 It shows Figure 11 is a block diagram of a work unit management system 10. Figure 3 It is a plan view showing production devices M3 to M7 as component mounting devices.

[0037] like Figures 1 to 3 As shown, the production system 1 is a production system 1 for producing products. For example, the products are mounted substrates 13 with components mounted thereon, semiconductors, or foods. The production system 1 includes a production line L and a work unit management system 10 .

[0038] Production line L is a production line for producing products. For example, if the product is a mounting substrate, production line L is a component mounting line for mounting components on substrate 13. Production line L includes a plurality of production devices M1 to M9, and operations are sequentially performed in the plurality of production devices M1 to M9 to produce the products.

[0039] Each of the plurality of production devices M1 to M9 is a production device for producing a product. The product is produced through a plurality of processes performed by the plurality of production devices M1 to M9. For example, in the case where the product is a mounting substrate, the production device M1 is a loader that supplies the substrate 13 to the production line L, and the production device M2 is a printing device that prints solder on the substrate 13. Furthermore, in the case where the product is a mounting substrate, for example, each of the plurality of production devices M3 to M7 is a component mounting device that mounts components on the substrate 13, the production device M8 is a reflow furnace that melts the solder printed on the substrate 13, and the production device M9 is a loader that discharges the mounting substrate from the production line L.

[0040] In addition, for example, the production system 1 may include one production device instead of a plurality of production devices. Therefore, the production devices M1 to M9 are just examples.

[0041] Each of the plurality of production devices M1 to M9 has a plurality of operating units. The plurality of operating units include operating units of different types. For example, the operating units are Figure 3 The components shown may be at least one of the mounting head 18 that moves the components for mounting on the substrate 13, the nozzle 19a that holds the components, and the feeder 14a that supplies the components. Thus, each of the multiple production devices M3 to M7 may only have multiple operating units. The nozzle 19a is an example of a holding unit.

[0042] In addition, each of the production devices M3 to M7 among the multiple production devices M1 to M9 has multiple areas E for performing operations on workpieces (work objects). For example, each of the production devices M3 to M7 has the function of mounting components on the substrate 13 in multiple areas E. A substrate conveying mechanism 12 is provided in the X direction at the center of the base 11 of each of the production devices M3 to M7. The substrate conveying mechanism 12 conveys the substrate 13 brought in from the upstream side in the X direction, positions and holds it at a position where the mounting operation is performed by the mounting head 18. Furthermore, the substrate conveying mechanism 12 carries out the substrate 13 on which the component mounting operation has been completed to the downstream side. Component supply devices 14 are provided on both sides of the substrate conveying mechanism 12. A Y-axis worktable 15 having a linear drive mechanism is arranged at both ends of the upper surface of the base 11 in the X direction. In the Y-axis worktable 15, a beam 17, which also has a linear mechanism, is coupled in a manner that allows it to move freely in the Y direction. On the beam 17, the mounting head 18 is assembled in a manner that allows it to move freely in the X direction. The mounting head 18 is equipped with multiple nozzle units 19. The Y-axis table 15 and beam 17 form a mounting head moving mechanism that moves the mounting head 18 in the horizontal direction (X and Y directions). The mounting head moving mechanism and the mounting head 18 pick up components from the component removal position of the feeder 14a attached to the component supply device 14 by suctioning them with the nozzles 19a of the nozzle unit 19. The mounting head moving mechanism then performs the following component mounting operation, moving the mounting head 18 to the mounting position on the substrate 13 held by the substrate transport mechanism 12 for mounting.

[0043] like Figure 1 as well as Figure 2 As shown, the work unit management system 10 manages the maintenance of each of the multiple work units possessed by the multiple production devices M1 to M9 in the production line L. The work unit management system 10 monitors each of the multiple production devices M1 to M9 that are automatically operated in real time. For example, the work unit management system 10 monitors each of the multiple production devices M1 to M9 in real time by obtaining measurement information that measures the status of the production device from each of the multiple production devices M1 to M9. The work unit management system 10 manages the maintenance of the production device based on the obtained measurement information. In addition, for example, the work unit management system 10 may not manage all of the multiple production devices M1 to M9, but may manage the maintenance of at least one of the multiple production devices M1 to M9.

[0044] The production system 1 and the work unit management system 10 have been described above.

[0045] Next, the functional configuration of the work unit management system 10 will be described.

[0046] The operation unit management system 10 includes a processing unit 20, a storage unit 31, an input unit 41, and a display unit 42. The operation unit management system 10 may include only the acquisition unit 21, the input unit 41, and the display unit 42 of the processing unit 20, and the other components are not essential.

[0047] The processing section 20 is realized by a processor or the like, and performs various processes.

[0048] Specifically, the processing unit 20 includes an acquisition unit 21 , a state determination unit 22 , a calculation unit 23 , a prediction unit 24 , and a migration unit 25 .

[0049] The acquisition unit 21 acquires measurement information indicating the status of each of the multiple operating units included in each of the multiple production devices M3 to M7 from each of the multiple production devices M3 to M7. In other words, the acquisition unit 21 acquires measurement information indicating the status of the multiple operating units included in the production device M3, measurement information indicating the status of the multiple operating units included in the production device M4, measurement information indicating the status of the multiple operating units included in the production device M5, measurement information indicating the status of the multiple operating units included in the production device M6, and measurement information indicating the status of the multiple operating units included in the production device M7. Furthermore, the acquisition unit 21 may also acquire measurement information indicating the status of the multiple operating units included in the production devices M1, M2, M8, and M9.

[0050] Furthermore, the acquisition unit 21 may acquire measurement information indicating the status of the plurality of operating units from at least one of the plurality of production devices M3 to M7, rather than from all of the plurality of production devices M3 to M7. Furthermore, the acquisition unit 21 may acquire measurement information from at least one of the plurality of operating units. For example, the measurement information may be images captured by a camera or the like and / or detection results from sensors.

[0051] Here, the measurement information is information indicating the status of the work unit. For example, the measurement information indicating the status of the multiple work units in the production device M3 includes information indicating the status of each of the one or more components constituting the multiple work units in the production device M3. Specifically, the measurement information indicating the status of the work units in the production device M3 includes at least the following information: information indicating the measurement value related to the air flowing within the mounting head 18, information indicating the sliding load value of the sliding portion 19b that causes the nozzle 19a to slide, information indicating the measurement value related to the air flowing within the nozzle 19a, information indicating an image of the front end of the nozzle 19a, and information related to the conveying accuracy of the components of the component supply device 14. For example, the state of the work unit can be known from the measurement information, such as the degradation state, wear state, dirt adhesion state, and positional deviation state of each of the one or more components constituting the work units in the production device M3. For example, the one or more components include the mounting head 18, the nozzle 19a, and the feeder 14a. The same applies to the measurement information indicating the status of the work units in production apparatus M4, the measurement information indicating the status of the work units in production apparatus M5, the measurement information indicating the status of the work units in production apparatus M6, and the measurement information indicating the status of the work units in production apparatus M7. Furthermore, the same applies to the measurement information indicating the status of the work units in production apparatuses M1, M2, M8, and M9.

[0052] The status determination unit 22 determines the status of each of the multiple operating units in each of the multiple production devices M3 to M7 based on each of the multiple measurement information obtained by the acquisition unit 21. The status of the multiple operating units includes multiple different types of status. The status determination unit 22 determines the status of each of the multiple operating units and outputs a status determination result indicating whether each of the multiple operating units is a target for maintenance. In other words, the status determination unit 22 determines the status of the operating units in the production device M3 based on the measurement information indicating the status of the operating units in the production device M3 and outputs a status determination result indicating whether the operating units in the production device M3 are a target for maintenance. Furthermore, the status determination unit 22 determines the status of the operating units in the production device M4 based on the measurement information indicating the status of the operating units in the production device M4 and outputs a status determination result indicating whether the operating units in the production device M4 are a target for maintenance. Furthermore, the status determination unit 22 determines the status of the operating units in the production device M5 based on the measurement information indicating the status of the operating units in the production device M5 and outputs a status determination result indicating whether the operating units in the production device M5 are a target for maintenance. Furthermore, the status determination unit 22 determines the status of the operating unit of the production apparatus M6 based on the measurement information indicating the status of the operating unit in the production apparatus M6, and outputs a status determination result indicating whether the operating unit in the production apparatus M6 is a target for maintenance. Furthermore, the status determination unit 22 determines the status of the operating unit in the production apparatus M7 based on the measurement information indicating the status of the operating unit in the production apparatus M7, and outputs a status determination result indicating whether the operating unit in the production apparatus M7 is a target for maintenance.

[0053] Furthermore, the status determination unit 22 may determine the status of the operating unit of the production device M1 based on the measurement information indicating the status of the operating unit in the production device M1, and output a status determination result indicating whether the operating unit in the production device M1 is a target for maintenance. Furthermore, the status determination unit 22 may determine the status of the operating unit of the production device M2 based on the measurement information indicating the status of the operating unit in the production device M2, and output a status determination result indicating whether the operating unit in the production device M2 is a target for maintenance. Furthermore, the status determination unit 22 may determine the status of the operating unit of the production device M8 based on the measurement information indicating the status of the operating unit in the production device M8, and output a status determination result indicating whether the operating unit in the production device M8 is a target for maintenance. Furthermore, the status determination unit 22 may determine the status of the operating unit of the production device M9 based on the measurement information indicating the status of the operating unit in the production device M9, and output a status determination result indicating whether the operating unit in the production device M9 is a target for maintenance.

[0054] The status determination result indicates the status of the operating unit, and the status determination result includes at least a normal status, an abnormal status, a recommended maintenance status, and a warning maintenance status. In this embodiment, the status determination result may also include an unmeasured status. For example, a normal status refers to a status in which the status of the operating unit is within the range of normal specifications. An abnormal status refers to a status in which the status of the operating unit is outside the range of normal specifications. The recommended maintenance status indicates a status within the range of normal specifications and reaching the threshold of the maintenance object (sometimes referred to as a quasi-normal status in the following description). The warning maintenance status indicates a status within the range of normal specifications and reaching the threshold of the warning maintenance. The unmeasured status indicates the initial status, or the status when the maintenance registration button of the operating unit management system 10 is pressed.

[0055] For example, the state determination unit 22 determines the state of the operating unit of the production device M3 based on the measurement information indicating the state of the operating unit in the production device M3, thereby outputting a state determination result indicating whether the operating unit in the production device M3 has a location requiring maintenance (whether it is a maintenance target). Specifically, for example, the state determination unit 22 determines the dirtiness of the feeder 14a in the production device M3 based on the brightness value of the feeder 14a in the image captured at the tape pocket position and the tip of the sprocket exposed by the feeder 14a in the production device M3. If the feeder 14a in the production device M3 is dirty enough to require cleaning, the state determination result is output indicating that the feeder 14a in the production device M3 is a maintenance target. In addition, for example, the status determination unit 22 determines the sliding state of the nozzle 19a in the production device M3 based on the detection result of the pressure sensor used to detect the sliding state of the nozzle 19a in the production device M3. When the nozzle 19a in the operating unit of the production device M3 is difficult to slide to the extent that it needs to be cleaned, the status determination result of the nozzle 19a in the operating unit of the production device M3 is output as a maintenance object.

[0056] For example, the status determination unit 22 similarly determines whether any of the operating units of production apparatus M4, M5, M6, and M7 require maintenance, and if so, outputs a status determination result identifying the required maintenance location as the maintenance target. Similarly, the status determination unit 22 determines whether any of the operating units of production apparatus M1, M2, M8, and M9 require maintenance, and outputs a status determination result.

[0057] For example, the status determination unit 22 stores the status determination result for each of the one or more components constituting the operating unit of the production device M3 in the storage unit 31. Similarly, the status determination unit 22 stores the status determination result for each of the one or more components constituting the operating unit of the production device M4, the production device M5, the production device M6, and the production device M7 in the storage unit 31. Similarly, the status determination unit 22 may store the status determination result for each of the one or more components constituting the operating unit of the production device M1, the production device M2, the production device M8, and the production device M9 in the storage unit 31.

[0058] The calculation unit 23 calculates a maintenance interval date and time for performing maintenance on the maintenance target based on past maintenance execution periods stored in the storage unit 31. The calculation 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 operating unit in the production device M3 calculated by the calculation unit 23 in order to perform maintenance on the operating unit.

[0059] Specifically, the calculation unit 23 obtains from the storage unit 31 a plurality of past maintenance execution periods for one or more components (such as the mounting head 18, the nozzle 19a, and the feeder 14a) constituting the operating unit of the production device M3. Based on the obtained plurality of past maintenance execution periods, the calculation unit 23 calculates the maintenance interval date and time for each of the one or more components constituting the operating unit of the production device M3. Furthermore, the calculation unit 23 can calculate the maintenance interval date and time for each of the one or more components constituting the operating unit of the production device M3 by increasing or decreasing the predetermined period based on the obtained plurality of past maintenance execution periods.

[0060] The calculation unit 23 stores the calculated maintenance interval date and time in the storage unit 31 for each of one or more components constituting the work unit in the production equipment M3 .

[0061] The calculation unit 23 also calculates the maintenance interval date and time for each of the operating units of the production apparatus M4, the production apparatus M5, the production apparatus M6, and the production apparatus M7, and stores the calculated maintenance interval date and time in the storage unit 31. Furthermore, the calculation unit 23 also calculates the maintenance interval date and time for each of the operating units of the production apparatus M1, the production apparatus M2, the production apparatus M8, and the production apparatus M9, and stores the calculated maintenance interval date and time in the storage unit 31.

[0062] Furthermore, the calculation unit 23 calculates the number of maintenance intervals for performing maintenance on the maintenance target based on the number of past operating times of the operating unit in the production device M3 stored in the storage unit 31. The calculation unit 23 stores the calculated number of maintenance intervals in the storage unit 31. The maintenance interval number is, for example, the number of operating times of the operating unit in the production device M3 calculated by the calculation unit 23 in order to perform maintenance on the operating unit. For example, the maintenance interval number is the number of operating times of the operating unit in the production device M3 during the period (operation period) between a maintenance implementation period and the next maintenance implementation period among multiple maintenance implementation periods in the past.

[0063] Specifically, the calculation unit 23 obtains a plurality of maintenance intervals implemented in the past for one or more components (mounting head 18, nozzle 19a, feeder 14a, etc.) constituting the operating unit in the production device M3 from the storage unit 31. For example, the calculation unit 23 obtains the maintenance interval number for each of the past multiple operating periods from the storage unit 31. The calculation unit 23 calculates the maintenance interval number for each of the one or more components constituting the operating unit in the production device M3 based on the obtained multiple maintenance interval numbers in the past. In addition, the calculation unit 23 increases or decreases the predetermined number based on the predetermined number and the obtained number of operations for each of the past multiple operating periods, thereby calculating the maintenance interval number for each of the one or more components constituting the operating unit in the production device M3.

[0064] The calculation unit 23 stores the calculated number of maintenance intervals in the storage unit 31 for each of one or more components constituting the work unit in the production equipment M3 .

[0065] Furthermore, the calculation unit 23 similarly calculates the number of maintenance intervals for each of the operating units of the production apparatus M4, the production apparatus M5, the production apparatus M6, and the production apparatus M7, and stores the calculated number of maintenance intervals in the storage unit 31. Furthermore, the calculation unit 23 similarly stores the calculated number of maintenance intervals for each of the operating units of the production apparatus M1, the production apparatus M2, the production apparatus M8, and the production apparatus M9 in the storage unit 31.

[0066] Furthermore, the calculation unit 23 calculates the deviations between the multiple maintenance interval dates and the multiple maintenance interval counts. Specifically, the calculation unit 23 calculates and compares the deviations between the multiple maintenance dates and times performed in the past and the multiple maintenance interval counts performed in the past for the operating unit of the production device M3. The calculation unit 23 outputs the maintenance date and time with the smaller deviation as a result of the comparison to the display unit 42. The calculation unit 23 stores the maintenance date and time with the smaller deviation in the operating unit of the production device M3 as the maintenance forecast date and time in the storage unit 31.

[0067] Furthermore, the calculation unit 23 similarly calculates the deviation between the multiple maintenance dates and times performed in the past and the deviation between the multiple maintenance intervals performed in the past for each of the operating units of the production apparatuses M4, M5, M6, and M7, and compares them, and outputs the maintenance date and time with the smaller deviation to the display unit 42. Similarly, the calculation unit 23 may also output the maintenance date and time with the smaller deviation to the display unit 42 for each of the operating units of the production apparatuses M1, M2, M8, and M9.

[0068] Furthermore, the calculation unit 23 similarly stores the maintenance date and time with the smaller deviation for each of the operation units of the production apparatuses M4, M5, M6, and M7 as the maintenance forecast date and time in the storage unit 31. Furthermore, the calculation unit 23 may similarly store the maintenance date and time with the smaller deviation for each of the operation units of the production apparatuses M1, M2, M8, and M9 as the maintenance forecast date and time in the storage unit 31.

[0069] The prediction unit 24 predicts a first next maintenance date based on the past maintenance intervals of the work unit in the production device M3 stored in the storage unit 31. Furthermore, the prediction unit 24 predicts a second next maintenance date based on the past maintenance interval counts of the work unit in the production device M3 stored in the storage unit 31. Furthermore, if a work unit has multiple maintenance targets, the prediction unit 24 predicts the first next maintenance date based on the maintenance intervals and the second next maintenance date based on the maintenance interval counts for each maintenance target, in other words, for each of the multiple work units.

[0070] The prediction unit 24 stores the first next maintenance date and the second next maintenance date, which are predicted for each of one or more components constituting the work unit in the production equipment M3 , in the storage unit 31 .

[0071] Furthermore, the prediction unit 24 also predicts the first next maintenance date and the second next maintenance date for each of the operating units of the production devices M4, M5, M6, and M7, and stores the predicted first next maintenance date and the second next maintenance date in the storage unit 31. Furthermore, the prediction unit 24 may also store the predicted first next maintenance date and the second next maintenance date in the storage unit 31 for each of the operating units of the production devices M1, M2, M8, and M9.

[0072] Furthermore, the prediction unit 24 also stores the maintenance prediction dates and times predicted in the past for the work unit of the production device M3 in the storage unit 31. Therefore, the prediction unit 24 can also predict the first next maintenance date and time and the second next maintenance date and time for the work unit of the production device M3, taking into account the past maintenance prediction dates and times.

[0073] The storage unit 31 stores various information as described above. For example, the storage unit 31 stores measurement information, status determination results, past maintenance execution times, maintenance interval dates and times, maintenance interval counts, maintenance forecast dates and times, the first next maintenance date and time, and the second next maintenance date and time. For example, the storage unit 31 is implemented by a memory or the like.

[0074] The transition unit 25 transitions the content displayed on the display unit 42 between a first screen and a second screen different from the first screen. Specifically, when the input unit 41 receives input from the user, the transition unit 25 transitions the content displayed on the display unit 42 from the first screen to the second screen, or vice versa. The first screen may be referred to as a first image, and the second screen may be referred to as a second image.

[0075] The input unit 41 receives input from the user. For example, in order to set multiple maintenance days and multiple maintenance deadlines, the input unit 41 receives input from the user. For example, the input unit 41 is implemented by a touch screen or hardware buttons.

[0076] The display unit 42 displays a display screen showing the status of the production line. The display screen displayed by the display unit 42 includes a production line screen that simulates the production line to show the status of the production line, and a determination result screen that displays, using visually distinguishable display objects, a status determination result indicating the status of one of the multiple operating units in the production devices M1 to M9 that has been selected according to predetermined conditions.

[0077] The predetermined condition is that, when the status determination results of multiple work units in a single production system are identical, the status determination results of the multiple work units are displayed on a determination result screen as a single status determination result for the production system. Therefore, when the status determination results of multiple work units are identical, the display unit 42 displays a determination result screen summarizing the status determination results of the single production system.

[0078] Furthermore, the predetermined condition is a condition for displaying the status determination results of a plurality of work units in a production apparatus separately on the determination result screen for each of the plurality of work units when the status determination results differ. Therefore, when the status determination results of the plurality of work units differ, the display unit 42 displays a determination result screen that displays the status determination results for each of the plurality of work units.

[0079] Furthermore, the display unit 42 displays a production equipment screen that categorizes the various work units corresponding to the production line screen. The production equipment screen is a screen included in the display screen that categorizes the various work units. Therefore, the user can easily identify the various work units categorized by category and displayed on the display unit 42 through the production equipment screen.

[0080] The display unit 42 displays a status determination result indicating the status of at least one of the multiple operating units of the multiple production devices M1 to M9. The display unit 42 is implemented by, for example, a liquid crystal panel or an organic electroluminescent panel.

[0081] The display unit 42 can also display at least one of the status determination results for each type of a plurality of different work units. Furthermore, the display unit 42 can also display the status determination results for each of the plurality of areas E where operations are performed on the plurality of production devices M1 to M9. Furthermore, the display unit 42 can also display a first screen including a production line screen and a determination result screen, and a second screen showing all the status determination results for the plurality of work units included in the selected area.

[0082] The display unit 42 can display 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 can display at least one of the first next maintenance date and time and the second next maintenance date and time for at least each work unit.

[0083] Furthermore, the display unit 42 can display the first next maintenance date and time or the second next maintenance date and time corresponding to the one with the smaller deviation among the plurality of maintenance interval dates and times and the plurality of maintenance interval times.

[0084] <Working unit monitoring list>

[0085] First, use Figure 4 The monitoring list for determining the status of the plurality of work units in the production equipment M3 to M7 by the status determination unit 22 will be described.

[0086] Figure 4This is a diagram showing a monitoring list of a work unit.

[0087] like Figure 4 As shown, the state determination unit 22 determines the state of a plurality of operating units in the production devices M3 to M7 in the production devices M1 to M9 based on the monitoring list. The monitoring list is composed of monitoring units that monitor the components of the operating units, namely the mounting head 18, the nozzle 19a, and the feeder 14a, monitoring items corresponding to the respective monitoring units, and contents corresponding to the monitoring items. Figure 4 Hereinafter, the mounting head 18 is sometimes simply referred to as a head.

[0088] For example, the state determination unit 22 determines the state of each monitoring unit that is a component of a plurality of work units in the production equipment M3 to M7 based on the monitoring unit, the monitoring item, and the description.

[0089] Specifically, in Figure 4 The figure shows the mounting head 18, nozzle 19a, and feeder 14a as an example of a monitoring unit. When the monitoring unit is the mounting head 18, the monitoring items are filter clogging and nozzle holder slippage. In the description, filter clogging can be 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, nozzle holder slippage can be determined by measuring the sliding load of the holder. When the monitoring unit is the nozzle 19a, the monitoring items are nozzle clogging and the nozzle tip state. In the description, nozzle clogging can be determined by measuring the flow rate of the nozzle 19a at a predetermined timing during the component adsorption operation of the nozzle 19a. In the description, the nozzle tip state can be determined by obtaining an image of the nozzle tip end at the timing of measuring the time-varying changes. When the monitoring unit is the feeder 14a, the monitoring item is the feeder conveying accuracy. In the description, the feeder conveying accuracy can be determined by estimating the belt mouth position at the timing of one rotation of the sprocket.

[0090] In this manner, the status determination unit 22 determines the status of the monitoring unit, in other words, the status of the plurality of operating units in the production devices M3 to M7, and outputs a status determination result as the result of the determination. The status determination unit 22 outputs the status determination result to the storage unit 31, thereby storing the status determination result in the storage unit 31. The status determination unit 22 also outputs the status determination result to the display unit 42, thereby displaying the status determination result on the display unit 42.

[0091] Next, use Figure 5 A status list will be described. The status list is a list for the display unit 42 to display status determination results of the plurality of work units in the production equipment M3 to M7.

[0092] Figure 5 It is a diagram showing a status list of the working unit.

[0093] like Figure 5 As shown, the display unit 42 displays the status determination result indicating the status of at least one of the multiple operating units. In other words, the display unit 42 displays the status determination result determined by the status determination unit 22. At this time, the display unit 42 displays the status determination result in different colors.

[0094] Specifically, Figure 5 The status list is composed of the status of the work unit, the display content indicating the status of the work unit, the color indicating the status of the work unit, and the description of the color indicating the status of the work unit.

[0095] The status of the operating unit is composed of a plurality of different states, such as the "unmeasured" state, the "normal" state, the "quasi-normal" state, the "warning maintenance" state, and the "abnormal" state. The display content is composed of a plurality of different contents, such as "unmeasured", "normal", "quasi-normal", "warning", and "abnormal". The color is composed of a plurality of different colors, such as a patternless color, green (thin oblique line texture), yellow-green (grid-like texture), yellow (thick oblique line texture), and red (dot-like texture). Here, the "normal" state is a state in which maintenance is not required. The "quasi-normal" state is a state in which there is extra time on the schedule even though it is time to perform maintenance. The "warning" state is a state in which it is the latter half of the period to perform maintenance, but the impact on the quality of the product is small. The "abnormal" state is a state that has a greater impact on the quality of the product, and is a state in which the operating unit is stopped.

[0096] For example, when the status and display content of the working unit is "not measured", the color is represented by a blank pattern. As an explanation of the color, the blank pattern indicates the initial state or the state when the maintenance registration button is pressed.

[0097] In addition, when the status and display content of the working unit are "normal", the color is green. As an explanation of the color, green indicates that the status is within the normal specification range.

[0098] When the status and display content of the work unit is "quasi-normal", the color is yellow-green. As an explanation of the color, yellow-green indicates that the status is within the normal specification range and has reached the threshold for maintenance.

[0099] If the status of the work unit is "Warning Maintenance" and the display content is "Warning", the color is yellow. As an explanation of the color, yellow indicates that the state is within the normal specification range and has reached the warning maintenance threshold.

[0100] In addition, when the status and display content of the working unit are "abnormal", the color is red. As an explanation of the color, red indicates a state outside the normal specification range.

[0101] In addition, Figure 5 The status of the work unit is indicated by colors, but is not limited to this. For example, the status of the work unit can also be indicated by symbols such as ○, △, and squares. In addition, the status of the work unit can also be indicated by letters such as A, B, and C.

[0102] <Display Screen and Time Series Screen>

[0103] Next, use Figure 6 To explain the display screen.

[0104] Figure 6 1 is a diagram showing the state of the production line L.

[0105] The display unit 42 displays a display screen. The display screen includes a production line screen simulating the production line L, a determination result screen within the production line screen, and a production equipment screen categorized by a plurality of different work units. The production line screen and the determination result screen are included in the first screen.

[0106] For example, a plurality of determination result screens simulating a plurality of work units arranged on the rear R side and the front F side are arranged in the production line screen. Figure 6 The production line screen displays multiple judgment result screens simulating multiple work units located on the rear R side and multiple judgment result screens simulating multiple work units located on the front F side. The judgment result screens display an "H" icon representing a mounting head, an "N" icon representing a nozzle, and an "F" icon representing a feeder as examples of work units. Furthermore, another judgment result screen displays an "OK" icon indicating that all components within a work unit are normal.

[0107] Each icon displayed on the determination result screen indicates a plurality of different states, namely, a "not measured" state, a "normal" state, a "quasi-normal" state, a "warning maintenance" state, and an "abnormal" state.

[0108] The leftmost judgment result screen (table) among the multiple judgment result screens arranged on the rear R side shows a yellow icon indicating "warning" corresponding to the "H" and "N" icons, and a yellow-green icon indicating "quasi-normal" corresponding to the "F" icon. The second judgment result screen on the left shows a yellow-green icon indicating "quasi-normal" corresponding to the "H" icon, and a green icon indicating "normal" corresponding to the "N" and "F" icons. The third, fourth, and sixth judgment result screens on the left show a green icon indicating "normal" corresponding to the "OK" icon. The fifth judgment result screen on the left shows a green icon indicating "normal" corresponding to the "H" icon, and a yellow-green icon indicating "quasi-normal" corresponding to the "N" and "F" icons.

[0109] The leftmost judgment result screen among the multiple judgment result screens arranged on the front F side displays a green icon indicating "normal" corresponding to the "H" icon, and a yellow-green icon indicating "quasi-normal" corresponding to the "N" and "F" icons. The second judgment result screen from the left displays a green icon indicating "normal" corresponding to the "H" and "N" icons, and a yellow-green icon indicating "quasi-normal" corresponding to the "F" icon. The third, fourth, fifth, and sixth judgment result screens from the left display green icons indicating "normal" corresponding to the "OK" icon.

[0110] In addition, in each of the multiple judgment result screens arranged on the rear R side and each of the multiple judgment result screens arranged on the front F side, the worst state among the states of the multiple mounting heads is represented by a colored icon, the worst state among the states of the multiple nozzles is represented by a colored icon, and the worst state among the states of the multiple feeders is represented by a colored icon.

[0111] In addition, Figure 6 In the figure, the production equipment screen is displayed below the first screen. The production equipment screen corresponds to the first screen. Figure 6 , the production device screen displays the content corresponding to the first screen.

[0112] The production device screen shows the "status" of the work unit, the "device name" of the work unit, a "table" representing a judgment result screen, the "location" of the work unit, the "unit" as the work unit, the "category" representing the work unit, the "monitoring object" in the work unit, and the "time" when the status of the work unit is measured.

[0113] exist Figure 6On the production equipment screen, you can select at least one of the "head" icon, "nozzle" icon, and "feeder" icon in the unit category column. By selecting at least one of the "head" icon, "nozzle" icon, and "feeder" icon, the "unit" corresponding to the selected icon is displayed on the production equipment screen. This allows multiple different work units to be displayed categorized by category on the production equipment screen.

[0114] Furthermore, on the production equipment screen, in the column displaying the priority category, you can select a "status" icon that displays the component status in order from worst to best, or a "device number" icon that displays the component status in order of device name. By selecting the "status" icon or the "device number" icon, the "units" on the production equipment screen are displayed in the order selected. In other words, the transition unit 25 transitions the content displayed on the production equipment screen in a manner corresponding to the selected "status" icon or the "device number" icon.

[0115] For example, in Figure 6 In the production device screen, the icons for "head", "nozzle", "feeder", and "status" are selected. In this case, for example, the first row of the production device screen shows the following: "Status" is warning, "Device Name" is NPM-WX-1, "Table" is 1, "Position" is 5, "Unit" is head, "Category" is 16 nozzle head, "Monitoring Target" is filter clogging, and "Time" is 2022 / 03 / 07 07:57. As another example, the second row of the production device screen shows the following: "Status" is warning, "Device Name" is NPM-WX-1, "Table" is 1, "Position" is 34, "Unit" is nozzle, "Category" is 230, "Monitoring Target" is nozzle clogging status, and "Time" is 2022 / 03 / 08 13:40.

[0116] Next, about Figure 6 In the display screen of , the second screen showing the status determination result of each content of "monitoring object" is used. Figure 7 To illustrate. Figure 7 The horizontal axis shows the past history (month and day) of the state changes of the "unit" in a time series, and the vertical axis shows the rate of state change. Although the horizontal axis shows the month and day, it can also be a date and time. The vertical axis shows the state of the working unit: from 0% to less than 80% is normal, from 80% to less than 100% is semi-normal, from 100% to less than 120% is a warning, and above 120% is abnormal. In addition, the annotation numbers displayed on the second screen indicate when the state of one or more components of the working unit is the worst in the time series.

[0117] Figure 7 This diagram shows the status determination results for each content of the "monitoring target" in a time-series screen. Figure 7 The upper side of the second screen is displayed Figure 6 The screen of the "unit" where the filter is clogged as the "monitoring object". The upper screen shows the "units" of 1F, 1R, 2F, 2R, 3F, 3R, 4F, 4R, 5F, 5R, 6F, and 6R as examples. Figure 7 2 shows a case where the “unit” is the nozzle unit 19 as an example.

[0118] Figure 7 The lower left screen of the second screen displays the status determination results of the "unit" 1F, a "monitored object" in which the filter is clogged, in a time series. The lower left screen shows the nozzles 19a from the 1nth to the 16nth nozzles 19a installed in the "unit" 1F as an example.

[0119] exist Figure 7 The lower right screen of the second screen is a screen that displays the status determination result of the 9n-th nozzle 19a among the 16 nozzles 19a in time series.

[0120] For example, when a user wants to view a "unit" in which a filter is clogged, the user Figure 6 When the user selects a "unit" in which filter clogging occurs via the input unit 41 in the production device screen of the production screen, the transition unit 25 makes Figure 6 The production screen is migrated to Figure 7 The second screen of the display unit 42 is displayed Figure 7 The upper side of the screen. Based on this, the user Figure 7 The upper screen of the can show the status of multiple "units" where filter clogging has occurred.

[0121] Next, in the multiple "units" on the upper screen, the user Figure 7 When the user selects "Unit" 1F via the input unit 41, the display unit 42 Figure 7 The lower left screen shows the status of the 1nth to 16nth nozzles 19a contained in the "unit" 1F. Figure 7 The lower left screen of can grasp the status of the 1nth to 16nth nozzles 19a included in the "unit".

[0122] Next, in the states of the 1nth to 16nth nozzles 19a in the lower left screen, the user Figure 7 When the user selects the 9nth nozzle 19a via the input unit 41, the display unit 42 displays Figure 7The lower right screen shows the state of the 9nth nozzle 19a. The lower right screen shows the worst state per hour. Figure 7 The lower right screen allows you to grasp the status of nozzles up to the 9nth nozzle included in the "unit", so you can perform detailed analysis, etc.

[0123] In addition, the migration unit 25 can make Figure 7 The second screen is moved to Figure 6 The production screen can also be used Figure 6 The production screen is migrated to Figure 7 's second screen.

[0124] In this way, through Figure 6 and Figure 7 The display screen shown allows the user to easily understand the status of the work unit in the production devices M3 to M7. In addition, the user can understand the details of the status of the work unit and the status of one or more components constituting the work unit.

[0125] <Status determination result screen>

[0126] Next, use Figures 8 to 11 The following describes the status determination results obtained by determining the status of the plurality of work units in the production devices M3 to M7 on the display unit 42 , namely, the status confirmation screen, the head inspection screen, the nozzle inspection screen, and the feeder inspection screen.

[0127] Figure 8 2 is a diagram showing a status confirmation screen as a result of status determination. Figure 9 1 is a diagram showing a head inspection screen as a result of status determination. Figure 10 FIG. 1 is a diagram showing a nozzle check screen as a result of status determination. Figure 11 It is a figure which shows the feeder inspection screen as a state determination result.

[0128] For example, the display unit 42 may be Figure 8 The status confirmation screen (or status confirmation image) showing the extracted status determination result of the operation unit is shown. A plurality of labels (or icons) are displayed in the status confirmation screen. One of the plurality of labels includes an item "Maintenance-Status Check" for maintaining the operation unit. In the status confirmation screen of "Maintenance-Status Check", the status determination result is displayed for each of a plurality of areas E. Figure 8The status confirmation screen shows the status determination results of the two areas "front side" and "rear side" as examples. In the status determination results, the "object unit" as the working unit and the "status" corresponding to the "object unit" are shown as examples. In the "object unit" of the two areas, the icon of "16 nozzle head", the icon of "nozzle" and the icon of "feeder" are shown as examples. In the "status" of the "front side", a yellow-green icon indicating "quasi-normal" corresponding to the icon of "16 nozzle head", a yellow icon indicating "warning" corresponding to the icon of "nozzle", and a red icon indicating "abnormal" corresponding to the icon of "feeder" are shown as examples. In the "status" of the "rear side", a patternless "-" icon corresponding to the icon of "16 nozzle head", a yellow icon indicating "warning" corresponding to the icon of "nozzle", and a red icon indicating "abnormal" corresponding to the icon of "feeder" are shown as examples.

[0129] In addition, although the status of multiple work units is displayed using colored icons in the status confirmation screen, for example, when the work unit is a "16-nozzle head", the icon of the color corresponding to the nozzle 19a with the worst status among the 16 nozzles 19a is displayed.

[0130] Next, in Figure 8 In the status confirmation screen shown, for example, when the user selects "16 nozzle head" of "front side", the display unit 42 displays Figure 9 For example, the screen displayed by the display unit 42 can be transferred between the first screen and the second screen. In other words, the display unit 42 can Figure 8 The status confirmation screen shown is the same as Figure 9 The head check screen shown transitions between the following. When the status confirmation screen is an example of the first screen, the head check screen is an example of the second screen. Also, when the head check screen is an example of the first screen, the status confirmation screen is an example of the second screen.

[0131] In the head inspection screen, the status of the plurality of nozzles 19a is displayed as a colored icon as the status of the working unit. In addition, in the head inspection screen, the position of each of the plurality of nozzles 19a is displayed as an icon such as POS ○○. ○○ is an arbitrary number. For example, in Figure 9 , icons from POS1 to POS16 indicating the positions of the 16 nozzles 19 a and icons indicating the states of the nozzles 19 a using colors, which are arranged adjacent to the respective icons, are shown as examples.

[0132] In addition, the head inspection screen displays filter clogging and retainer slippage as icons as specific states of the plurality of nozzles 19a. The head inspection screen displays filter clogging and retainer slippage in a manner that allows users to identify the nozzles 19a in which the filter clogging and retainer slippage occur.

[0133] For example, in Figure 9 In the head inspection screen, if the filter is clogged, the status of each of the nozzles 19a at POS1 to POS16 indicating the position of the nozzle 19a is displayed as an icon indicating the color.

[0134] Next, in Figure 8 In the status confirmation screen shown, for example, when the user selects "Nozzle" of "Rear Side", the display unit 42 displays Figure 10 The nozzle check screen (nozzle check image) shown in FIG. Figure 8 The status confirmation screen shown is the same as Figure 10 The nozzle check screen shown transitions between the two. When the status confirmation screen is an example of the first screen, the nozzle check screen is an example of the second screen. Also, when the nozzle check screen is an example of the first screen, the status confirmation screen is an example of the second screen.

[0135] In the nozzle check screen, the status of the plurality of nozzles 19a is displayed as a colored icon as the status of the working unit. In addition, in the nozzle check screen, the automatic exchange position of the plurality of nozzles 19a is displayed as an icon such as F○○. For example, in Figure 10 As an example, icons F11 to F18 and F21 to F28 indicating the automatic exchange position of the nozzle 19 a and icons indicating the state of the nozzle 19 a in colors, which are arranged adjacent to the respective icons, are shown.

[0136] The nozzle check screen displays icons showing nozzle clogging and tip status as specific states of the multiple nozzles 19a. The nozzle check screen displays icons showing which nozzles 19a are clogged or have tip status.

[0137] For example, in Figure 10 In the nozzle check screen, if a nozzle is clogged, icons representing the status of the nozzles 19a in colors F11 to F18 and F21 to F28 indicating the positions of the nozzles 19a are displayed.

[0138] Next, in Figure 8 In the status confirmation screen shown, for example, when the user selects "feeder" of "front side", the display unit 42 displays Figure 11The display unit 42 can display the feeder inspection screen (feeder inspection image) shown in FIG. Figure 8 The status confirmation screen shown is the same as Figure 11 The feeder inspection screen shown transitions between the following. When the status confirmation screen is an example of the first screen, the feeder inspection screen is an example of the second screen. Also, when the feeder inspection screen is an example of the first screen, the status confirmation screen is an example of the second screen.

[0139] In the feeder inspection screen, the status of the plurality of feeders 14a is displayed as a colored icon as the status of the operation unit. In addition, in the feeder inspection screen, the plurality of feeders 14a are displayed as a digital icon. For example, Figure 11 , icons indicating the numbers of the 17 feeders 14a and icons indicating the status of the feeders 14a by color, which are arranged adjacent to the respective icons, are shown as an example.

[0140] In addition, as a specific state of the plurality of feeders 14a, the component conveyance accuracy is displayed as an icon on the feeder inspection screen. The component conveyance accuracy of each of the plurality of feeders is displayed on the feeder inspection screen so that the feeder 14a can be known.

[0141] For example, in Figure 11 The component conveying accuracy of each of the plurality of feeders 14a is displayed as a colored icon on the feeder inspection screen.

[0142] Thus, in this embodiment, Figure 8 As shown in the status confirmation screen, the status of the operating unit in each of the multiple areas E, in other words, the status of one or more components constituting the operating unit, is displayed separately, making it easy to understand the status of the operating unit to be maintained. In addition, because the status of the component with the worst status is displayed on the status confirmation screen, it is easy to understand whether the component is a component to be maintained.

[0143] Furthermore, when the user selects the icon of the "16-nozzle head" exemplified as the "target unit" of the operation unit on the status confirmation screen via the input unit 41, the transition unit 25 transitions the status confirmation screen to the head inspection screen, and the display unit 42 displays the head inspection screen. Thus, the user can understand the status of the mounting head 18 as the operation unit and the maintenance period of the mounting head 18 through the head inspection screen.

[0144] Furthermore, when the user selects the "nozzle" icon, which is exemplified as the "target unit" of the operating unit, on the status confirmation screen via the input unit 41, the transition unit 25 transitions the status confirmation screen to the nozzle check screen, and the nozzle check screen is displayed on the display unit 42. Thus, the user can understand the status of the nozzle 19a, which is the operating unit, and the maintenance period of the nozzle 19a, etc., through the nozzle check screen.

[0145] Furthermore, when the user selects the "feeder" icon, which is illustrated as a "feeder" as an operation unit, on the status confirmation screen via the input unit 41, the transition unit 25 transitions the status confirmation screen to the feeder inspection screen, and the display unit 42 displays the feeder inspection screen. Thus, the user can understand the status of the feeder 14a as the operation unit and the maintenance period of the feeder 14a through the feeder inspection screen.

[0152] This operation unit management device can also achieve the same effects as those described above.

[0153] In addition, the work unit management method involved in this embodiment is a method for managing multiple work units possessed by a production device on a production line, where multiple production devices operate sequentially on the production line to produce products. The work unit management method includes: obtaining measurement information of the status of multiple work units possessed by the production device by the acquisition unit 21; determining the status of the multiple work units based on the measurement information by the status determination unit 22; and displaying a display screen showing the status of the production line by the display unit 42. The display screen displayed by the display unit 42 includes a production line screen simulating the production line and a determination result screen that displays the following status determination result using a visually distinguishable display object, wherein the status determination result is a status determination result that represents the status of a work unit selected according to specified conditions among the status determination results representing the status of multiple work units in the production device.

[0154] This operation unit management method can also achieve the same effects as described above.

[0155] Furthermore, the program according to the present embodiment is a program for causing a computer to execute the work unit management method.

[0156] This program can also produce the same effects as described above.

[0157] As described above, in the work unit management system 10 according to this embodiment, the status determination results indicate the statuses of the plurality of work units, and include at least a normal status, an abnormal status, a maintenance recommended status, and a maintenance warning status.

[0158] As a result, the display unit 42 can display the status of the working unit as at least one of normal, abnormal, maintenance recommendation, and maintenance warning, so that the user can easily understand the status of the working unit.

[0159] As described above, in the work unit management system 10 according to this embodiment, the plurality of work units include work units of different types. The display unit 42 displays the status determination results determined for each type of the plurality of different work units.

[0160] As a result, the status determination result is displayed on the display unit 42 for each type of the plurality of work units. Therefore, the user can recognize the status determination result indicating the status of the work unit for each type of the plurality of work units.

[0161] As described above, in the work unit management system 10 according to this embodiment, the production device includes a plurality of areas E for producing products. The display unit 42 displays the status determination result for each of the plurality of areas E.

[0162] As a result, the status determination result is displayed on the display unit 42 for each of the plurality of areas E. Therefore, the user can recognize the status determination result indicating the status of the work unit for each of the plurality of areas E.

[0163] As described above, in the work unit management system 10 according to this embodiment, the display unit 42 displays a first screen and a second screen. The first screen includes a production line screen and a determination result screen, and the second screen displays all status determination results for the multiple work units included in the selected area. Furthermore, the display unit 42 includes a transition unit 25 that transitions the displayed content between the first and second screens.

[0164] With this, the display unit 42 can display, as the first screen, the production line screen and the determination result screen that displays the status of the work unit as visually distinguishable display objects.

[0165] Furthermore, the display unit 42 displays all the status determination results of the plurality of operation units as the second screen, so that the user can recognize the status determination results indicating the status of all the plurality of operation units and can visually check the detailed status of all the operation units.

[0166] As a result, the user can easily grasp the status of the work unit of the production equipment.

[0167] In addition, as described above, in the work unit management system 10 involved in this embodiment, the prescribed condition is that when the status judgment results of multiple work units in a production device are the same, the status judgment results of multiple work units are used as the status judgment results of the production device to display the judgment result screen.

[0168] Accordingly, when the status determination results for multiple operating units are identical, the display unit 42 displays the status determination results as a single production device having multiple operating units, thereby not displaying the status determination results for all of the multiple operating units. This reduces the amount of information on the determination result screen displayed on the display unit 42, thereby improving user visibility. As a result, the user can easily understand the status of the operating units through the determination result screen.

[0169] In addition, as described above, in the work unit management system 10 involved in this embodiment, the prescribed condition is that when the status judgment results of multiple work units in one of the production devices are different, the status judgment results are displayed separately on the judgment result screen for each of the multiple work units.

[0170] Accordingly, when the status determination results for multiple operating units differ, the display unit 42 displays the different status determination results as a determination result screen, separately for each of the multiple operating units. This allows the user to understand the status determination results for each operating unit and create an appropriate maintenance plan. Consequently, the status of each operating unit can be understood via the determination result screen.

[0171] As described above, the work unit management system 10 according to this embodiment includes a production equipment screen in which a plurality of different work units are classified into categories. The display unit 42 displays the production equipment screen in which a plurality of different work units corresponding to the production line screen are classified.

[0172] Thus, the user selects a work unit whose details he wants to view from among the multiple work units displayed on the production line screen, and the display unit 42 can display the production device screen showing the selected work unit. Therefore, the user can visually confirm the detailed status of the work unit.

[0173] As described above, in the work unit management system 10 according to this embodiment, the production device is a component mounting device that mounts components on the substrate 13. Furthermore, the work unit is at least one of the component supply device 14 that supplies components, the holding portion (nozzle 19a) that holds the components, and the mounting head 18 that moves the holding portion.

[0174] According to this, when the work unit management system 10 is applied to a component mounting apparatus, the user can easily grasp the status of the work unit in the component mounting apparatus.

[0175] In addition, as described above, in the work unit management system 10 involved in this embodiment, the measurement information is at least the measurement value related to the air flowing in the mounting head 18, the sliding load value of the sliding portion 19b that causes the holding portion to slide, the measurement value related to the air flowing in the holding portion, the image of the front end of the holding portion, and information related to the conveying accuracy of the components of the component supply device 14.

[0176] Thus, the state determination unit 22 can determine the states of the plurality of working units based on the measurement information. Therefore, the display unit 42 can display whether the state of the working unit is normal, abnormal, maintenance recommended, or maintenance warning.
