[0014] One embodiment is described in detail below with reference to the drawings.

[0015] It should be noted that the embodiment described below represents a general or specific example. The numerical values, shapes, materials, components, arrangement and connection of the components, steps, processing sequence of the steps, etc., shown in the following embodiment are merely examples and are therefore not intended to limit the present disclosure. Furthermore, those components in the following embodiment that are not mentioned in any of the independent claims are described as optional components.

[0016] Furthermore, the drawings are schematic and not necessarily precise representations. Identical components in the drawings have the same reference symbols. [Version]<Funktionskonfiguration: Arbeitseinheit-Managementsystem 10>

[0017] First, with reference to Fig. 1 to Fig. 3 describes the production system 1 which includes the work unit management system 10 according to the present embodiment.

[0018] Fig. Figure 1 is a schematic diagram illustrating the work unit management system 10 according to the embodiment. Fig. 2 is a block diagram representing the work unit management system 10 in Fig. 1 illustrates. Fig. Figure 3 is a top view illustrating any one of the production devices M3 to M7, which are component assembly devices.

[0019] As in Fig. 1 to Fig. As shown in Figure 3, production system 1 is a production system for manufacturing a product. Examples of the product include food, a semiconductor, and an assembled substrate, which is a substrate 13 onto which components, etc., have been mounted. Production system 1 has a production line L and a work unit management system 10.

[0020] Production line L is a production line for manufacturing the product. For example, if the product is an assembled substrate, production line L is a component assembly line for mounting components onto substrate 13. Production line L has a multitude of production devices M1 to M9 and manufactures the product by sequentially operating the multitude of production devices M1 to M9.

[0021] Each of the multiple production devices M1 to M9 is a production device for manufacturing the product. The product is manufactured through a multiple process performed by the multiple production devices M1 to M9. For example, if the product is a populated substrate, production device M1 is a loading device that feeds the substrate 13 to production line L, and production device M2 is a printing device that prints solder onto the substrate 13. If the product is a populated substrate, for example, each of the production devices M3 to M7 is a component mounting device that mounts a component onto the substrate 13, production device M8 is a reflow oven that melts the solder printed onto the substrate 13, and production device M9 is a loader that ejects the populated substrate from production line L.

[0022] It should be noted that production system 1, for example, may have a single production device instead of a multitude of production devices. Therefore, production devices M1 to M9 are merely an example.

[0023] Each of the numerous production devices M1 to M9 comprises a multitude of work units. These numerous work units include various types of work units. For example, in Fig. As shown in Figure 3, each work unit can be at least one of the following: an assembly head 18 that moves and mounts a component onto the substrate 13, a nozzle 19a that holds a component, or a feeding device 14a that feeds a component. Therefore, each of the production devices M3 to M7 can easily have a plurality of work units. The nozzle 19a is an example of a holder.

[0024] Among the numerous production devices M1 to M9, production devices M3 to M7 have a number of areas E in which work is carried out on a workpiece (work target). For example, each of the production devices M3 to M7 has a function for mounting a component onto the substrate 13 in the several areas E. In the center of the base 11 in each of the production devices M3 to M7, a substrate conveying mechanism 12 is provided in the X-direction. The substrate conveying mechanism 12 conveys the substrate 13, introduced from the upstream side, in the X-direction and positions and holds the substrate 13 in a position where the assembly head 18 is to perform the component assembly work. Furthermore, the substrate conveying mechanism 12 conveys the substrate 13, on which the component assembly work is completed, to the downstream side. A component feeding device 14 is provided on both sides of the substrate conveying mechanism 12.A Y-axis table 15, which has a linear drive mechanism, is arranged at both ends of the top of the base 11 in the X-direction of the base 11. A support 17, which also has a linear mechanism, is coupled to the Y-axis table 15 such that the support 17 can move in the Y-direction. The mounting head 18 is attached to the support 17 such that the mounting head 18 is movable in the X-direction. A plurality of nozzle units 19 are provided on the mounting head 18. The Y-axis table 15 and the support 17 form a mounting head movement mechanism that moves the mounting head 18 in the horizontal direction (the X-direction, the Y-direction). Using the nozzle 19a of the nozzle unit 19, the component assembly head movement mechanism and the assembly head 18 suck up and pick up a component from a component removal position of the feeder 14a, which is attached to the component feeder unit 14.The component assembly head motion mechanism then performs component assembly operations by moving the assembly head 18 to an assembly position on the substrate 13, which is held by the substrate conveying mechanism 12, and then assembling the component.

[0025] As in Fig. 1 and Fig. As shown in Figure 2, the work unit management system 10 is a device that manages the maintenance of each of the multiple work units located in the multiple production devices M1 to M9 of production line L. The work unit management system 10 monitors each of the multiple production devices M1 to M9 in real time, which operate automatically. For example, the work unit management system 10 monitors each of the multiple production devices M1 to M9 in real time by receiving measurement information from each of the multiple production devices M1 to M9, obtained by measuring the condition of the production device. The work unit management system 10 manages the maintenance of the production device based on the received measurement information.It should be noted that, for example, the work unit management system 10 can manage the maintenance of at least one production device among the multitude of production devices M1 to M9 instead of all of the multitude of production devices M1 to M9.

[0026] Production System 1 and Work Unit Management System 10 were described above.

[0027] Next, a functional configuration of the workspace management system 10 is described.

[0028] The work unit management system 10 comprises a processing unit 20, a memory 31, an input receiver 41, and a display 42. It should be noted that the work unit management system 10 can simply consist of the acquisition device 21 of the processing unit 20, the input receiver 41, and the display 42, and the other components are not essential.

[0029] For example, processing unit 20 is implemented as a processor and executes various processes.

[0030] In particular, the processing unit 20 includes a detection device 21, a state determination device 22, a computing unit 23, a predictor 24 and a transmitter 25.

[0031] Acquisition device 21 acquires measurement information from each of the plurality of production devices M3 to M7, obtained by measuring the state of each of the plurality of work units contained in the production device. That is, acquisition device 21 acquires: measurement information indicating the states of the plurality of work units contained in production device M3; Measurement information indicating the states of the multitude of work units contained in production device M4; measurement information indicating the states of the multitude of work units contained in production device M5; measurement information indicating the states of the multitude of work units contained in production device M6; and measurement information indicating the states of the multitude of work units contained in production device M7. Additionally, the sensing device 21 can acquire measurement information indicating the states of the multitude of work units contained in production devices M1, M2, M8, and M9.

[0032] It should be noted that the sensing device can acquire 21 measurement information indicating the states of a plurality of work units, specifically from at least one production device among production devices M3 to M7, rather than from all production devices M3 to M7. Furthermore, the sensing device can acquire 21 measurement information from at least a plurality of work units. This measurement information includes, for example, an image captured by a camera or similar device and / or a sensor reading or similar.

[0033] Here, the measurement information is information that specifies the states of work units. For example, the measurement information that specifies the states of the multitude of work units contained in the production device M3 includes information that specifies the state of each of the components that are the multitude of work units contained in the production device M3.In particular, the measurement information indicating the conditions of the work units contained in the production device M3 includes at least: information indicating a measurement value regarding the air flowing in the assembly head 18; information indicating a sliding load value of the slide 19b that moves the nozzle 19a; information indicating a measurement value regarding the air flowing in the nozzle 19a; information showing an image of the tip of the nozzle 19a; and information regarding the component feeding accuracy of the component feeding device 14. Using this measurement information, the user can, for example, determine the deterioration state, wear state, contamination state, and misalignment state of each or more work units contained in the production device M3 as the condition of each individual or multiple work units.For example, each individual or multiple work units has an assembly head 18, a nozzle 19a, and a feeder 14a. The same applies to: the measurement information indicating the states of the work units contained in production device M4; the measurement information indicating the states of the work units contained in production device M5; the measurement information indicating the states of the work units contained in production device M6; and the measurement information indicating the states of the work units contained in production device M7. The same can also apply to the measurement information indicating the states of the work units contained in production devices M1, M2, M8, and M9.

[0034] The condition determination device 22 determines the states of the multitude of work units contained in the multitude of production devices M3 to M7, based on a multitude of measurement information points acquired by the detection device 21. The states of the multitude of work units exhibit various types of conditions. The condition determination device 22 determines the states of the multitude of work units and outputs a condition determination result indicating for each of the multitude of work units whether maintenance should be performed.This means that the condition monitoring device 22 determines the states of the work units contained in the production device M3 based on the measurement information indicating the states of the work units contained in the production device M3, and outputs a condition monitoring result indicating whether maintenance should be performed on the work units contained in the production device M3. The condition monitoring device 22 also determines the states of the work units contained in the production device M4 based on the measurement information indicating the states of the work units contained in the production device M4, and outputs a condition monitoring result indicating whether maintenance should be performed on the work units contained in the production device M4.The condition monitoring device 22 also determines the states of the work units contained in the production device M5 based on the measurement information indicating the states of the work units contained in the production device M5, and outputs a condition monitoring result indicating whether maintenance should be performed on the work units contained in the production device M5. The condition monitoring device 22 also determines the states of the work units contained in the production device M6 based on the measurement information indicating the states of the work units contained in the production device M6, and outputs a condition monitoring result indicating whether maintenance should be performed on the work units contained in the production device M6.The condition determination device 22 also determines the states of the work units contained in the production device M7 on the basis of the measurement information indicating the states of the work units contained in the production device M7, and outputs a condition determination result indicating whether maintenance should be carried out on the work units contained in the production device M7.

[0035] Furthermore, the condition monitoring device 22 can determine the states of the work units contained in the production device M1 based on the measurement information indicating the states of the work units contained in the production device M1 and output a condition monitoring result indicating whether maintenance should be performed on the work units contained in the production device M1. The condition monitoring device 22 can also determine the states of the work units contained in the production device M2 based on the measurement information indicating the states of the work units contained in the production device M2 and output a condition monitoring result indicating whether maintenance should be performed on the work units contained in the production device M2.The condition monitoring device 22 can also determine the states of the work units contained in the production device M8 based on the measurement information indicating the states of the work units contained in the production device M8, and output a condition monitoring result indicating whether maintenance should be performed on the work units contained in the production device M8. The condition monitoring device 22 can also determine the states of the work units contained in the production device M9 based on the measurement information indicating the states of the work units contained in the production device M9, and output a condition monitoring result indicating whether maintenance should be performed on the work units contained in the production device M9.

[0036] The condition determination result indicates the states of a plurality of working units and includes at least one normal state, one anomalous state, one maintenance-recommending state, and one maintenance-warning state. In the present embodiment, the condition determination result may also include an unmeasured state. For example, the normal state indicates that the working unit's condition is within normal specifications. The anomalous state indicates that the working unit's condition is outside of normal specifications. The maintenance-recommending state indicates that the working unit's condition is within normal specifications and is a state in which a maintenance threshold has been reached (hereinafter also referred to as the semi-normal state). The maintenance-warning state indicates that the working unit's condition is within normal specifications and that a maintenance-warning threshold has been reached.The unmeasured state indicates the initial state or a state in which a maintenance registration button of the work unit management system 10 is pressed.

[0037] For example, the condition determination device 22 determines the states of the work units contained in the production device M3 based on the measurement information that indicates the states of the work units contained in the production device M3, and outputs a condition determination result that indicates whether the work units contained in the production device M3 have a part that needs to be serviced (whether maintenance should be performed).In particular, the condition determination device 22 determines, for example, the condition of dirt on the feeder 14a contained in the production device M3, based on the illumination value of the feeder 14a in a captured image of an exposed tip of a gear and a belt pocket position of the feeder 14a contained in the production device M3, and outputs a condition determination result indicating that maintenance should be carried out on the feeder 14a contained in the production device M3 if the feeder 14a contained in the production device M3 is so dirty that cleaning is required.Furthermore, for example, the condition determination device 22 determines the sliding state of the nozzle 19a, which is contained in the production device M3, based on a detection result of a pressure sensor used to detect the sliding state of the nozzle 19a, which is contained in the production device M3, and outputs a condition determination result indicating that maintenance should be carried out on the nozzle 19a, which is a working unit of the production device M3, if the sliding of the nozzle 19a, which is a working unit of the production device M3, is made more difficult to such an extent that the nozzle 19a needs to be cleaned.

[0038] For example, the condition monitoring device 22 determines in the same way for each of the work units contained in production device M4, production device M5, production device M6, and production device M7 whether the work unit has a part that requires maintenance, and if the work unit has a part that requires maintenance, the condition monitoring device 22 outputs a condition result indicating that maintenance should be performed on that part. The condition monitoring device 22 can also determine in the same way for each of the work units contained in production device M1, M2, M8, and M9 whether the work unit has a part that requires maintenance and output a condition result accordingly.

[0039] For example, the state determination device 22 stores the state determination result for each of the one or more work units contained in the production device M3 in memory 31. Similarly, the state determination device 22 also stores the state determination result for each of the one or more work units contained in the production devices M4, M5, M6, and M7 in memory 31. Likewise, the state determination device 22 can also store the state determination result for each of the work units contained in the production devices M1, M2, M8, and M9 in memory 31.

[0040] Computer 23 calculates a maintenance interval period for performing maintenance based on a past maintenance point stored in memory 31. Computer 23 stores the calculated maintenance interval period in memory 31. The maintenance interval period is, for example, the operating period of a specific work unit of production equipment M3, which is calculated by computer 23 for performing maintenance on that specific work unit of production equipment M3.

[0041] In particular, the computer 23 receives from memory 31 a plurality of maintenance execution times in the past for one or more work units (e.g., assembly head 18, nozzle 19a, and feeder 14a) that are part of the production device M3. Based on this plurality of past maintenance execution times, the computer 23 calculates the maintenance interval time for each of the one or more work units contained in the production device M3. It should be noted that the computer 23 can calculate the maintenance interval time for each of the one or more work units contained in the production device M3 by increasing or decreasing a predetermined duration based on the predetermined duration and the plurality of past maintenance execution times obtained.

[0042] The computer 23 stores the calculated maintenance interval period for each of the one or more work units contained in the production device M3 in a memory 31.

[0043] Similarly, computer 23 also calculates the maintenance interval period for each of the work units of production device M4, production device M5, production device M6, and production device M7 and stores the calculated maintenance interval periods in a memory 31. It should be noted that computer 23 can also calculate the maintenance interval time for each of the work units of production device M1, production device M2, production device M8, and production device M9 in the same way and store the calculated maintenance interval times in memory 31.

[0044] Furthermore, computer 23 calculates a maintenance interval counter for performing maintenance based on the number of operations previously performed by a specific work unit of production device M3, which are stored in memory 31. Computer 23 stores the calculated maintenance interval counter in memory 31. The maintenance interval counter is, for example, the number of operations to be performed by a specific work unit of production device M3 and is calculated by computer 23 to determine when maintenance is required on that specific work unit of production device M3.For example, the maintenance interval number is the number of operations performed by a specific work unit during a period (operating period) between a specific maintenance time and the next maintenance time from a multitude of maintenance times at which maintenance was performed in the past.

[0045] In particular, the computer 23 receives a multitude of past maintenance interval counts from memory 31 with respect to one or more work units (for example, the assembly head 18, the nozzle 19a, and the feeder 14a) contained in the production device M3. For example, the computer 23 receives the maintenance interval count for each of a multitude of past work periods from memory 31. Based on the recorded multitude of past maintenance interval counts, the computer 23 calculates the maintenance interval count for each of the one or more work units contained in the production device M3.It should be noted that the computer 23 can calculate the maintenance interval count for each of one or more work units contained in the production device M3 by increasing or decreasing a predetermined count based on the predetermined count and the recorded number of operations carried out in each of a multitude of operating periods in the past.

[0046] The computer 23 stores the calculated number of maintenance intervals for each of the one or more work units contained in the production device M3 in a memory 31.

[0047] In the same way, computer 23 also calculates the number of maintenance intervals for each of the work units in production devices M4, M5, M6, and M7 and stores the calculated maintenance interval numbers in memory 31. It should be noted that computer 23 can also calculate the number of maintenance intervals for each of the work units in production devices M1, M2, M8, and M9 in the same way and store the calculated maintenance interval numbers in memory 31.

[0048] Furthermore, the computer 23 calculates a deviation for each of the multiple maintenance interval periods and for each of the multiple maintenance interval counts. Specifically, for a given work unit of the production device M3, the computer 23 calculates a deviation for each of the multiple maintenance dates and times at which maintenance was performed in the past, and a deviation for each of the multiple maintenance interval counts in the past. Based on the calculation result, the computer 23 outputs a low-deviation maintenance date and time to the display 42. The computer 23 stores the low-deviation maintenance date and time in memory 31 as the predicted maintenance date and time for the given work unit of the production device M3.

[0049] For a given unit of work for each of the production devices M4, M5, M6, and M7, the computer 23 calculates a deviation for each of a multitude of maintenance dates and times at which maintenance was performed in the past, and a deviation for each of the multitude of maintenance interval counts in the past, and outputs a maintenance date and time with a small deviation to the display 42. It should be noted that the computer 23 can also output a maintenance date and time with a small deviation to the display 42 for a given unit of work for each of the production devices M1, M2, M8, and M9 in the same way.

[0050] Similarly, computer 23 also stores the maintenance date and time, with a slight deviation, in memory 31 as the predicted maintenance date and time for the given unit of work of each of the production devices M4, M5, M6, and M7. It should be noted that computer 23 can also store the maintenance date and time, with a slight deviation, in memory 31 as the predicted maintenance date and time for the given unit of work of each of the production devices M1, M2, M8, and M9.

[0051] Based on the past maintenance interval period of a specific work unit of production device M3, stored in memory 31, predictor 24 forecasts a first next maintenance date and time. Based on the past maintenance interval counter of the specific work unit of production device M3, also stored in memory 31, predictor 24 forecasts a second next maintenance date and time. If maintenance is to be performed on a plurality of work units, predictor 24 forecasts, for each of the plurality of work units to be maintained, the first next maintenance date and time based on the maintenance interval count, and the second next maintenance date and time based on the maintenance interval count.

[0052] The predictor 24 stores in memory 31 the first next maintenance date and the first next maintenance time that were predicted for each of the one or more work units contained in the production device M3.

[0053] Similarly, the predictor 24 also predicts the first next maintenance date and time, as well as the second next maintenance date and time, for each of the work units contained in production device M4, production device M5, production device M6 and production device M7, and stores the predicted first next maintenance date and time, as well as the second next maintenance date and time, in memory 31.It should be noted that the predictor 24 can also store in memory 31 the first next maintenance date and first next maintenance time as well as the second next maintenance date and second next maintenance time that were predicted for each of the work units contained in production device M1, production device M2, production device M8 and production device M9.

[0054] Predictor 24 also stores in memory 31 a previously predicted maintenance date and time for a specific work unit of production device M3. Therefore, predictor 24 can predict the next maintenance date and time for that specific work unit of production device M3, taking into account the previously predicted maintenance date and time.

[0055] Memory 31 stores various types of information, as described above. For example, memory 31 stores measurement information, the condition determination result, the time of past maintenance, the maintenance interval period, the number of maintenance intervals, the predicted maintenance date and time, the first next maintenance date and time, the second next maintenance date and time, and so on. For example, memory 31 is implemented as memory or the like.

[0056] Transformer 25 causes a transition between a first screen displayed by display 42 and a second screen displayed by display 42 that differs from the first screen. Specifically, when input receiver 41 receives an input from the user, transformer 25 causes the content displayed by display 42 to transition from the first screen to the second screen, or vice versa. The first screen can be described as the first image, and the second screen can be described as the second image.

[0057] The input receiver 41 receives input from the user. For example, the input receiver 41 receives input from the user to set a variety of maintenance dates and maintenance deadlines. For example, the input receiver 41 is implemented as a touch panel, hardware button, or the like.

[0058] Display 42 shows a screen displaying the status of the production line. The display screen shown by display 42 includes: a production line screen representing the production line to indicate its status; and a status result screen, which, using a visually distinguishable symbol, displays a status result indicating the status of at least one of a plurality of work units contained in production devices M1 to M9. These work units are selected from status results based on a predetermined condition, indicating the status of the plurality of work units.

[0059] The predetermined condition is a condition that if the state determination results of the plurality of work units contained in a production device are the same, a determination result screen is displayed that shows the state determination results of the plurality of work units as the state determination result of the single production device. Therefore, if the state determination results of the plurality of work units are the same, display 42 shows a determination result screen that summarizes the state determination results of the plurality of work units as the state determination result of the single production device.

[0060] Furthermore, the predetermined condition is that if the state determination results of the plurality of work units contained in a production device are different, the state determination results are displayed in individual determination result screens, each corresponding to a different plurality of work units. Therefore, display 42 shows, if the state determination results of the plurality of work units are different, determination result screens that display the individual state determination results of the plurality of work units.

[0061] Display 42 shows the production equipment screen, which classifies a variety of different work units displayed on the production line screen by type. The production equipment screen is a screen integrated within the display screen and allows the user to easily identify the various work units displayed and classified by type on display 42.

[0062] The display 42 shows a state determination result indicating the state of at least one work unit among the states of a plurality of work units contained in the production devices M1 to M9. Such a display 42 is, for example, designed as a liquid crystal display, organic electroluminescent display (EL display), or the like.

[0063] Display 42 can also show at least one of the status determination results determined for different types of work units. Display 42 can also show a status determination result for each of the plurality of areas E in which work is performed on a workpiece of each of the plurality of production devices M1 to M9. Display 42 can also show: the first screen, which contains the production line screen and the status result screen; and the second screen, which shows the status determination results of all of the plurality of work units contained in the selected area.

[0064] Display 42 can also show at least one of the first next maintenance date and time or the second next maintenance date and time. For example, display 42 can also show at least one of the first next maintenance date and time or the second next maintenance date and time for each of one or more work units.

[0065] Display 42 can also display the first next maintenance date and the first next maintenance time with a small deviation, or the second next maintenance date with a small deviation, based on a variety of maintenance interval periods and a variety of maintenance interval counts. <Monitoring list of work units>

[0066] First, with reference to Fig. 4 a monitoring list for determining the states of the plurality of work units that are shown in the production devices M3 to M7, described by the state determination device 22.

[0067] Fig. Figure 4 is a diagram illustrating a monitoring list of work units.

[0068] As in Fig. As shown in Figure 4, the state determination device 22 determines, based on the monitoring list, the states of the plurality of work units contained in the production devices M3 to M7 under the production devices M1 to M9. The monitoring list includes: monitored units, which specify as monitoring targets the assembly head 18, the nozzle 19a, and the feeder 14a, the work units; monitored points corresponding to the monitored units; and a description corresponding to the monitored points. It should be noted that in Fig. 4 and the following drawings, the mounting head 18 can simply be referred to as the head.

[0069] For example, the condition determination device 22 determines the condition of each of the monitored units, which are the multitude of work units contained in the production devices M3 to M7, based on the monitored units, the monitored points and the description.

[0070] In particular, it shows Fig. 4. The assembly head 18, the nozzle 19a, and the feeder 14a are given as examples of the monitored units. If the monitored unit is the assembly head 18, the monitored points are filter clogging and nozzle holder slippage. The description states that filter clogging is determined by measuring the flow rate of the assembly head 18 at a predetermined time during a component assembly operation performed by the assembly head 18. The description states that nozzle holder slippage is determined by measuring the sliding load on the holder. If the monitored unit is the nozzle 19a, the monitored points are nozzle clogging and the nozzle tip condition. The description states that nozzle clogging is determined by measuring the flow rate of the nozzle 19a at a predetermined time during a component suction operation performed by the nozzle 19a.The description states that the nozzle tip condition is determined by capturing an image of the nozzle tip section at the time of measuring a change over time. If the monitored unit is the feeder 14a, the monitored point is the feeder's feeding accuracy. The description states that the feeder's feeding accuracy is determined by estimating the belt pocket position at the time a gear completes one revolution.

[0071] In the manner described above, the state determination device 22 determines the states of the monitored units, i.e., the states of the multitude of work units located in the production devices M3 to M7, and outputs the state determination results. The state determination device 22 outputs the state determination results to the memory 31 for storage. The state determination device 22 also outputs the state determination results to the display 42, which then displays the state determination results.

[0072] Next, with reference to Fig. 5 a status list for displaying the status determination results, which indicate the results of the determination of the states of the plurality of work units contained in the production devices M3 to M7, as described by display 42.

[0073] Fig. Figure 5 is a diagram illustrating a state list of work units.

[0074] As in Fig. As shown in Figure 5, the display unit 42 shows a state determination result that indicates at least one state among the states of a plurality of working units. That is, the display unit 42 shows the state determination result determined by the state determination device 22. The display unit 42 displays the state determination result using different colors.

[0075] In particular, the condition list in Fig. 5. The following: the state of a work unit; display content that indicates the state of the work unit; a color that indicates the state of the work unit; and a description of the color that indicates the state of the work unit.

[0076] The status of a work unit, for example, has a variety of different states, such as "Not Measured," "Normal," "Semi-Normal," "Maintenance Warning," and "Anomalous." The display content includes a variety of different options, such as "Not Measured," "Normal," "Semi-Normal," "Warning," and "Anomalous." The color, for example, includes a variety of different colors, such as solid, green (hatching with thin diagonal lines), yellow-green (hatching in a grid pattern), yellow (hatching with thick diagonal lines), and red (dotted hatching). Here, the "normal" state is a state in which no maintenance is required. The "Semi-Normal" state is a state in which maintenance is due, but there is still sufficient time remaining in the schedule.The "Warning" condition is a state in which maintenance is in the second half of its due period, but the impact on product quality is minor. The "Anomalous" condition is a state in which the impact on product quality is significant and the work unit has been stopped.

[0077] For example, if the status and display content of a work unit is "Not Measured," the color is solid. As the color description indicates, solid color signifies an initial state or a state in which the maintenance recording button is pressed.

[0078] If the state and display content of a working unit are "Normal", the color is green. The color green means that the working unit's state is within normal specifications.

[0079] When the status and display content of a work unit are "Semi-normal," the color is yellow-green. Yellow-green indicates that the work unit's condition is within normal specifications and a maintenance threshold has been reached.

[0080] When a work unit's status is "Maintenance Warning" and the display content is "Warning," the color is yellow. As the color description indicates, yellow means that the work unit's status is within normal specifications and a maintenance warning threshold has been reached.

[0081] If the state and display content of a work unit are "anomalous," the color is red. As the color description indicates, red signifies that the work unit's state is outside of normal specifications.

[0082] It should be noted that in Fig. 5 etc. The states of the work units are indicated by colors, but the present disclosure is not limited to this. For example, the states of the work units can be indicated by symbols such as a circle, a triangle, and a square. Alternatively, the states of the work units can be indicated by letters such as A, B, and C. <Anzeigebildschirm und chronologischer Bildschirm>

[0083] Next, the display screen will be shown with reference to Fig. 6 described.

[0084] Fig. Figure 6 is a diagram illustrating the state of production line L.

[0085] Display 42 shows the display screen. The display screen includes: a production line screen representing production line L; a results screen located within the production line screen; and a production equipment screen classifying a variety of different work units by type. The production line screen and the results screen are contained within the first screen.

[0086] For example, a multitude of determination result screens, representing a multitude of work units, are arranged on the rear (R) and front (F) sides of the production line screen. The production line screen in Fig. Figure 6 shows a variety of determination result screens representing a variety of work units located on the rear (R) and a variety of determination result screens representing a variety of work units located on the front (F). Some of the determination result screens display an "H" symbol indicating an assembly head, an "N" symbol indicating a nozzle, and an "F" symbol indicating a feeder as examples of work units. Other determination result screens display an "OK" symbol indicating that all components are in a normal condition.

[0087] The symbols displayed on the test result screens indicate a variety of different states, such as the "Not measured" state, the "Normal" state, the "Semi-normal" state, the "Maintenance warning" state, and the "Anomalous" state.

[0088] Among the test result screens located on the rear right side, the leftmost screen (table) displays yellow symbols indicating "Warning" for the symbols "H" and "N," and a yellow-green symbol indicating "Semi-normal" for the symbol "F." The second test result screen from the left displays a yellow-green symbol for "Semi-normal" for the symbol "H" and green symbols for "Normal" for the symbols "N" and "F." The third, fourth, and sixth test result screens from the left each display a green symbol for "Normal" for the symbol "OK." The fifth test result screen from the left displays a green symbol for "Normal" for the symbol "H" and yellow-green symbols for "Semi-normal" for the symbols "N" and "F."

[0089] Among the numerous test result screens arranged on the front panel F, the leftmost screen displays a green icon indicating "Normal" for the "H" symbol and yellow-green icons indicating "Semi-normal" for the "N" and "F" symbols. The second screen from the left displays green icons indicating "Normal" for the "H" and "N" symbols and a yellow-green icon indicating "Semi-normal" for the "F" symbol. The third, fourth, fifth, and sixth screens from the left each display a green icon indicating "Normal" for the "OK" symbol.

[0090] Note that in each of the multiple determination result screens located on the rear R-side, and in each of the multiple determination result screens located on the front F-side, the most unfavorable condition among the multiple assembly head states is indicated by a colored symbol, the most unfavorable condition among the multiple nozzle states is indicated by a colored symbol, and the most unfavorable condition among the multiple feeder states is indicated by a colored symbol.

[0091] In Fig. 6. The production equipment screen is displayed below the first screen. The production equipment screen is identical to the first screen. In Fig. 6 shows the production device screen displaying content that corresponds to the first screen.

[0092] The production equipment screen displays the "status" of a work unit, the "device name" of the work unit, a "table" that displays a determination result screen, the "position" of the work unit, the "unit" that is the work unit, the "type" that indicates the work unit, the "monitoring target" of the work unit, and the "time" at which the status of the work unit was measured.

[0093] In the "Unit Type" section, which is displayed on the production equipment screen in Fig. As shown in Figure 6, at least one of the symbols "Head," "Nozzle," or "Feeder" can be selected. Selecting at least one of these symbols displays the corresponding "Unit" on the production device's screen. Therefore, it is possible to display a variety of different work units on the production device's screen, classified by type.

[0094] In the "Display Priority" section, which appears on the production device's screen, either a "Status" icon can be selected to display components sorted in ascending order of their status, starting with the component in the worst condition, or a "Device Number" icon to display components sorted by device name. Selecting either the "Status" or "Device Number" icon displays the "units" on the production device's screen in the order selected. In other words, transmitter 25 switches the content displayed on the production device's screen according to the icon selected from the "Status" and "Device Number" options.

[0095] For example, the production equipment screen shows... Fig. 6. The "Head," "Nozzle," "Feeder," and "Status" symbols are selected. In this case, for example, the first line of the production equipment screen displays "Status" as a warning; "Device Name" displays NPM-WX-1; "Table" is 1; "Position" is 5; "Unit" is Head; "Type" is 16-Nozzle Head; "Monitoring Target" is Filter Clogging; and "Time" is 2022 / 03 / 07 07:57. As another example, the second line of the production line screen displays "Status" as a warning; "Device Name" displays NPM-WX-1; "Table" displays 1; "Position" is 34; "Unit" is Nozzle; "Type" is 230; "Monitoring Target" is Nozzle Clogging Status; and "Time" is 2022 / 03 / 08 13:40.

[0096] Next, with reference to Fig. 7. The second screen is described, which shows the status determination result for each point of "monitoring target" that appears on the display screen in Fig. 6 is shown. Fig. Figure 7 shows the horizontal axis displaying past records (month and date) in chronological order, showing the progress of the state change of the "unit," and the vertical axis represents the rate of state change. Although the horizontal axis displays month and date, it can also display date and time. The vertical axis shows the state of a work unit; a range of 0% to less than 80% means "Normal," a range of 80% to less than 100% means "Semi-Normal," a range of 100% to less than 120% means "Warning," and 120% or more means "Anomalous." Each of the numbers appended to the chronological graph displayed on the second screen indicates the point in time at which one or more components of a work unit were in their most unfavorable state.

[0097] Fig. Figure 7 is a diagram illustrating status determination results for each "monitoring target" on chronological screens. The top screen of the second screen in Fig. Screen 7 displays the number of "units" in which the filter has become clogged, as described in Fig. 6 is shown as the "monitoring target". The upper screen shows "units" 1F, 1R, 2F, 2R, 3F, 3R, 4F, 4R, 5F, 5R, 6F and 6R as an example. Fig. Figure 7 shows an example where "unit" is nozzle unit 19.

[0098] The lower left screen of the second screen in Fig. Screen 7 displays a chronological status result for "Unit" 1F where a filter blockage has occurred as the "monitoring target". The screen in the lower left shows, as an example, the 1nth to 16nth nozzle 19a intended for "Unit" 1F.

[0099] The lower right screen of the second screen in Fig. 7 is a screen that chronologically displays a status determination result of the 9nth nozzle 19a among 16 nozzles 19a.

[0100] For example, if the user wants to display "units" where a filter blockage has occurred, and selects "units" where a filter blockage has occurred via input receiver 41, the transmitter 25 causes a transition from the display screen to Fig. 6 to the second screen in Fig. 7. If the user selects the “units” in which a filter blockage has occurred, the transmitter 25 causes a transition from the display screen to Fig. 6 to the second screen in Fig. 7, and display 42 thus shows the upper screen in Fig. 7. Accordingly, the user can access the upper screen in Fig. 7. Record the conditions of a large number of “units” in which a filter blockage has occurred.

[0101] Next, if the user selects "Unit" 1F from the multitude of "Units" displayed on the top screen in Fig. 7 is displayed, and when input receiver 41 is selected, display 42 is shown on the lower left screen. Fig. 7 displays the states of the 1nth to 16nth nozzles 19a, which are contained in "unit" 1F. Accordingly, the user can access the lower left screen in Fig. 7 record the states of the 1nth to 16nth nozzles 19a contained in “unit” 1F.

[0102] Next, if the user selects the 9nth nozzle 19a from the states of the 1nth to 16nth nozzles 19a, which are shown on the lower left screen in Fig. When 7 is displayed, and input receiver 41 is selected, display 42 shows the status of the 9nth nozzle 19a on the lower right screen. Fig. 7. The lower right screen displays the most unfavorable state in the hour-by-hour chart. Accordingly, the user can access the lower right screen. Fig. 7. Detect the condition of the 9nth nozzle, which has 1F in “unit”, thus enabling detailed analysis, etc.

[0103] It should be noted that the transmitter 25 provides a transition from the second screen to Fig. 7 to the display screen in Fig. 6 and a transition from the display screen to Fig. 6 to the second screen in Fig. 7 can cause.

[0104] Accordingly, the in Fig. 6 and Fig. The seven display screens shown allow the user to easily understand the status of the work units contained in the production devices M3 to M7. Furthermore, the user can view details of the work unit statuses and the status of one or more components contained within the work units. <Bildschirme der Zustandsbestimmungsergebnisse>

[0105] Next, with reference to Fig. 8 to Fig. 11 a status check screen, a main check screen, a nozzle check screen and a feeder inspection screen are described, which show condition determination results obtained by determining the states of the plurality of work units contained in the production devices M3 to M7.

[0106] Fig. Figure 8 is a diagram showing a status check screen displaying status determination results. Fig. Figure 9 is a diagram showing a main inspection screen displaying condition assessment results. Fig. Figure 10 is a diagram showing a nozzle check screen displaying condition assessment results. Fig. Figure 11 is a diagram showing a feeder inspection screen displaying condition assessment results.

[0107] For example, the display shows 42, as in Fig. Figure 8 shows a status check screen (or status check image) from which condition assessment results from work units have been extracted. The status check screen displays a variety of branches (or icons). One of the many branches has a "Maintenance - Condition Check" option to perform maintenance on one or more work units. The "Maintenance - Condition Check" status check screen displays a condition assessment result for each of the many areas E. For example, the status check screen in Fig. 8. A status result is displayed for each of the two areas, namely "Front" and "Rear". For example, the status result shows "Target Unit", which indicates a unit of work, and "Status", which indicates the "Target Device". For example, "Target Device" displays a "16-Nozzle Head" symbol, a "Nozzle" symbol, and a "Feeder" symbol for each of the two areas. For example, "Status" for "Front" displays a yellow-green symbol indicating "Semi-Normal" for the "16-Nozzle Head" symbol, a yellow symbol indicating "Warning" for the "Nozzle" symbol, and a red symbol indicating "Anomaly" for the "Feeder" symbol. For example, “Status” for “Rear” shows a simple symbol “-” for the “16-Nozzle Head” symbol, a yellow “Warning” symbol for the “Nozzle” symbol, and a red “Anomaly” symbol for the “Feeder” symbol.

[0108] The status check screen displays colored icons indicating the status of a variety of work units. For example, for "16-nozzle head," an icon in a color corresponding to nozzle 19a, which is in the worst condition among the 16 nozzles 19a, is displayed.

[0109] Next, if, for example, the user selects "16-nozzle head" on "front" on the status check screen, which is in Fig. As shown in Figure 8, display 42 shows a head check screen (head check image) which is in Fig. 9 is shown. For example, display 42 can switch between the first screen and the second screen. That is, display 42 can switch between the one shown in Fig. 8 status check screen shown and the one in Fig. Switch between the main check screens shown in section 9. If the status check screen is an example of the first screen, the main check screen is an example of the second screen. If the main check screen is an example of the first screen, the status check screen is an example of the second screen.

[0110] The nozzle check screen displays colored symbols indicating the states of a multitude of nozzles 19a as states of working units. The nozzle check screen also displays symbols "POS **" indicating the positions of the multitude of nozzles 19a. "**" denotes any number. For example, it shows... Fig. 9 symbols “POS1” to “POS16” that indicate the positions of 16 nozzles 19a, and symbols located next to the symbols “POS1” to “POS16” that indicate the states of the nozzles 19a by means of colors.

[0111] Furthermore, the main test screen displays symbols indicating filter clogging and holder slippage as specific conditions for the multiple nozzles 19a. The main test screen is displayed in such a way that the user can identify the positions of the nozzles 19a where filter clogging and holder slippage have occurred.

[0112] For example, the main exam screen shows in Fig. 9 symbols, which indicate by color the status of the nozzles 19a at positions POS1 to POS16 with regard to a blockage of the filter.

[0113] Next, display 42 shows, for example, when the user selects "nozzle" on "back" on the in Fig. Select the status check screen shown in 8, which is displayed in Fig. The nozzle test screen (nozzle test image) shown in 10 is displayed. Display 42 can be set to the one shown in Fig. 8 status check screen shown and the one in Fig. The nozzle check screen shown in the 10 images can be switched between. If the status check screen is an example of the first screen, the nozzle check screen is an example of the second screen. If the nozzle check screen is an example of the first screen, the status check screen is an example of the second screen.

[0114] The nozzle check screen displays colored symbols indicating the states of the multiple nozzles 19a as working unit states. The nozzle check screen also displays symbols "F**" indicating the changeover positions of the multiple nozzles 19a. Fig. 10 shows symbols “F11” to “F18” and “F21” to “F28”, which indicate the changer positions of the nozzles 19a, as well as symbols located next to the symbols “F11” to “F18” and “F21” to “F28”, which indicate the states of the nozzles 19a by means of colors.

[0115] Furthermore, the nozzle check screen displays symbols indicating nozzle blockage and the condition of the nozzle tips as specific states for the multitude of nozzles 19a. The nozzle check screen is displayed in such a way that the user can identify the nozzle blockage and the condition of the nozzle tips of each of the multitude of nozzles 19a, as well as the positions of the multitude of nozzles 19a.

[0116] For example, the nozzle check screen in Fig. 10 symbols, indicated by colors, show the condition of nozzles 19a, located at F11 to F18 and F21 to F28, with regard to nozzle clogging.

[0117] For example, the display will show 42 next, if the user selects "Feeder" on "Front" on the status check screen, which is located in Fig. 8 is shown, selects the feeder inspection screen (feeder inspection image), which is in Fig. 11 is shown. Display 42 can be set between the one in Fig. 8 status check screen shown and the one in Fig. The feeder inspection screen shown in Figure 11 can be switched between. If the status check screen is an example of the first screen, the feeder inspection screen is an example of the second screen. If the feeder inspection screen is an example of the first screen, the status check screen is an example of the second screen.

[0118] The feeder inspection screen displays colored symbols indicating the status of the multiple feeders 14a as states of work units. The feeder inspection screen also displays numerical symbols indicating the status of the multiple feeders 14a. For example, it shows Fig. 11 numerical symbols indicating 17 feeders 14a, and symbols arranged adjacent to the numerical symbols indicating the states of the feeders 14a by color.

[0119] Furthermore, the feeder inspection screen displays symbols indicating the component feeding accuracy as specific states of the multitude of feeders 14a. The feeder inspection screen is displayed in such a way that the user can identify the component feeding accuracy of each of the multitude of feeders.

[0120] For example, the feeder inspection screen shows in Fig. 11 symbols, which indicate by color the component feeding accuracy of each of the several feeders 14a.

[0121] As described above, in the present embodiment, the states of the working units in each of the plurality of areas E, i.e., the state of each of one or more components contained in the working units, are displayed, as in the Fig.The status check screen shown in Figure 8 allows the user to easily identify the status of work units that require maintenance. Since the status check screen also displays the condition of the component in the worst state, the user can easily see if any component requires maintenance.

[0122] When the user selects the symbol “16-nozzle head” via the input receiver 41, which is a work unit listed as a “target unit” on the status check screen, the transmitter 25 causes a transition from the status check screen to the main check screen, and the display 42 then shows the main check screen. Accordingly, the user can, for example, retrieve the statuses of the assembly heads 18, which are work units, and the maintenance times of the assembly heads 18 from the main check screen.

[0123] When the user selects the "nozzle" symbol via input receiver 41, which is a work unit listed as a "target unit" on the status check screen, transmitter 25 causes a transition from the status check screen to the nozzle check screen, and display 42 then shows the nozzle check screen. Accordingly, the user can, for example, retrieve the status of nozzles 19a, which are work units, and the maintenance times of nozzles 19a from the nozzle check screen.

[0124] When the user selects the "Feeder" symbol via input receiver 41, which is a work unit listed as a "Target Unit" on the status check screen, the transmitter 25 causes a transition from the status check screen to the feeder inspection screen, and the display 42 then shows the feeder inspection screen. Accordingly, the user can, for example, view the status of feeders 14a, which are work units, and the maintenance times of feeders 14a on the feeder inspection screen. <Vorteilhafte Wirkungen>

[0125] Next, advantageous effects of the work unit management system 10, the work unit management device, the work unit management procedure and the program according to the present embodiment will be described.

[0126] As described above, the work unit management system 10 according to the present embodiment is a work unit management system that manages a plurality of work units located in a plurality of production devices (for example, M1 to M9) of the production line L, which produces a product by sequential operation through the plurality of production devices, wherein the work unit management system comprises: a sensing device 21 that acquires measurement information obtained by measuring the states of a plurality of work units located in a production device located in the plurality of production devices; a state determination device 22 that determines the states of the plurality of work units located in the production device based on the measurement information;and a display 42, which displays a display screen showing a production line situation. The display screen shown by the display 42 includes: a production line screen representing the production line; and a determination result screen, which, using a visually distinguishable symbol, displays a state determination result indicating a state of at least one of the plurality of work units contained in the one production device, wherein the state determination result is selected from state determination results indicating the states of the plurality of work units contained in the one production device based on a predetermined condition.

[0127] Accordingly, display 42 can show the determination result screen, which uses a visually distinguishable symbol to indicate the state determination result, specifying the state of at least one work unit selected based on a predetermined condition. Therefore, display 42 can, for example, show the state of a work unit that is in the worst state among a large number of work units. In other words, display 42 can avoid showing a work unit that is in a favorable state. As described above, display 42 can display information while simultaneously reducing the number of symbols displayed; that is, display 42 can reduce the amount of information shown on the display screen, thereby improving visibility for the user.

[0128] Therefore, according to the embodiment, the work unit management system 10 enables the user to easily record the states of work units of a production device.

[0129] Furthermore, the work unit management device according to the present embodiment is a work unit management system 10 that manages a plurality of work units contained in a plurality of production devices of a production line that produces a product by sequential operation through the plurality of production devices, wherein the work unit management device comprises: a sensing device 21 that acquires measurement information acquired by measuring the states of a plurality of work units contained in a production device that is included in the plurality of production devices; a state determination device 22 that determines the states of the plurality of work units contained in the one production device based on the measurement information;and a display 42, which displays a screen showing a production line situation. The screen displayed by the display 42 includes: a production line screen representing the production line; and a determination result screen, which, using a visually distinguishable symbol, displays a state determination result indicating a state of at least one of the plurality of work units contained in the one production device, wherein the state determination result is selected from state determination results indicating the states of the plurality of work units contained in the one production device based on a predetermined condition.

[0130] This work unit management device also produces the same beneficial effects as those described above.

[0131] Furthermore, the work unit management method according to the present embodiment is a work unit management method for managing a plurality of work units contained in a plurality of production devices of a production line that produces a product by sequential operation through the plurality of production devices, wherein the work unit management method comprises: acquiring measurement information obtained by measuring the states of a plurality of work units contained in a production device that is included in the plurality of production devices by a acquiring device 21; determining the states of the plurality of work units contained in the production device by a state determination device 22 based on the measurement information; and displaying a display screen showing a situation of the production line by a display 42.The display screen shown by display 42 includes: a production line screen representing the production line; and a determination result screen which, using a visually distinguishable symbol, displays a state determination result indicating a state of at least one of the plurality of work units contained in the one production device, wherein the state determination result is selected on the basis of a predetermined condition from state determination results indicating the states of the plurality of work units contained in the one production device.

[0132] The procedure for managing work units also produces the same beneficial effects as those described above.

[0133] Furthermore, a program according to the present embodiment is a program that causes a computer to execute the procedure for managing work units.

[0134] This program also produces the same beneficial effects as those described above.

[0135] Furthermore, as described above, in the work unit management system 10 according to the present embodiment, the condition determination result indicates the condition of at least one of the plurality of work units and has at least one normal state, one anomalous state, one maintenance recommendation state and one maintenance warning state.

[0136] Accordingly, display 42 can show one of at least the following states for each working unit: the normal state, the abnormal state, the maintenance-recommending state, and the maintenance-warning state. Therefore, the user can easily ascertain the states of the working units.

[0137] Furthermore, as described above, in the work unit management system 10 according to the present embodiment, the plurality of work units comprise different types of work units. The display 42 shows the status determination result that was determined for each of the different types of work units.

[0138] Accordingly, since display 42 shows the status determination result for each type of workstation, the user can identify the status determination result for each type of workstation, which indicates the state of the workstation.

[0139] Additionally, as described above, in the workstation management system 10 according to the present embodiment, the production device has a plurality of areas E for manufacturing the product. The display 42 shows the status determination result for each of the plurality of areas E.

[0140] Accordingly, since display 42 shows the status determination result for each of the multitude of areas E, the user can recognize the status determination result that shows the states of the work units for each of the multitude of areas E.

[0141] Furthermore, as described above, the display 42 in the work unit management system 10 according to the present embodiment shows: a first screen comprising the production line screen and the determination result screen; and a second screen displaying status determination results of all of a plurality of work units contained in a selected area. The work unit management system 10 further comprises a transmitter 25 that facilitates a transition between the first screen and the second screen.

[0142] Accordingly, display 42 can show the production line screen and the determination result screen as the first screen, which uses a visually distinguishable symbol to indicate the status of at least one work unit. Therefore, visibility for the user can be improved.

[0143] Furthermore, display 42, as a second screen, shows all status determination results for the numerous work units. Therefore, the user can see the status determination results indicating the status of all work units and visually identify the status of all work units in detail.

[0144] As a result, the user can easily monitor the states of the production equipment's work units.

[0145] Furthermore, as described above, in the work unit management system 10 according to the present embodiment, the predetermined condition is a condition that if the status determination results of the plurality of work units contained in the one production device are the same, the determination result screen is displayed to show the status determination results of the plurality of work units as the status determination result of the one production device.

[0146] Accordingly, if the status determination results of the multiple work units contained in the single production device are the same, display 42 shows a status result screen representing the status determination result of that single production device containing the multiple work units, and thus does not display the status determination results of all the multiple work units. Therefore, it is possible to reduce the amount of information displayed on the status result screen by display 42, thereby improving user visibility. As a result, the user can easily understand the statuses of the work units from the status result screen.

[0147] Furthermore, as described above, in the work unit management system 10 according to the present embodiment, the predetermined condition is a condition that if the status determination results of the plurality of work units contained in the one production device are different, the status determination results are displayed in individual determination result screens, each corresponding to a different plurality of work units.

[0148] Accordingly, if the condition assessment results for the multiple work units differ, display 42 shows the different condition assessment results in separate assessment result screens, each corresponding to a different work unit. Since the user can thus record each of the condition assessment results, it becomes possible to create a suitable maintenance plan. This makes it easy to understand the condition of the work units from the assessment result screens.

[0149] Furthermore, the display unit in the work unit management system 10 according to the present embodiment, as described above, has a production equipment screen in which the multitude of different work units are classified by type. The display 42 shows the production equipment screen in which the multitude of different work units shown on the production line screen are classified.

[0150] Accordingly, when the user selects a work unit to view its details, display 42 can show a production device screen displaying the selected work unit from among the many work units shown on the production line screen. Therefore, the user can visually assess the status of the work units in detail.

[0151] Furthermore, as described above, in the work unit management system 10 according to the present embodiment, one production device included in the plurality of production devices is a component assembly device that mounts a component onto the substrate 13. At least one work unit included in the plurality of work units contained in the one production device is at least one of the component feeding devices 14 that feeds the component, a holder (nozzle 19a) that holds the component, or an assembly head 18 that moves the holder.

[0152] Accordingly, when the work unit management system 10 is applied to a component assembly fixture, the user can easily ascertain the states of the work units contained in the component assembly fixture.

[0153] Additionally, as described above, the work unit management system 10 according to the present embodiment contains measurement information relating to at least: a measured value relating to air flowing into the assembly head 18; a sliding load value of the sliding piece 19b that allows the holder to slide; a measured value relating to air flowing into the holder; an image of a tip of the holder; and a feeding accuracy when feeding the component by the component feeding unit 14.

[0154] Accordingly, the state determination device 22 can determine the states of a plurality of working units based on such measurement information. Therefore, the display 42 can show the state of the working units, namely the normal state, the abnormal state, the maintenance recommendation state, or the maintenance warning state. [Other variants]
