[0002] A conventional display system or similar device is known that enables a production device, which mounts components onto a substrate, to maintain its operational capability by servicing a plurality of work units contained within the production device, such as an assembly head and a component feeding device. Since the production device incorporates various sensors, it is possible to monitor the status of the plurality of work units using these sensors. Therefore, the production device must allow for the straightforward determination of which of the plurality of work units requires maintenance.

[0004] [PTL 1] WO 2020 / 240773 [Summary of the invention][Technical problem]

[0005] Although PTL 1 displays a situation where an incident occurs in the component assembly system, it is difficult to identify which assembly unit is in an unfavorable condition for which component.

[0006] In light of the above, the present disclosure provides a display system and the like, which enables a user to easily ascertain the states of work units of a production device. [Solution to the task]

[0007] A display system according to one aspect of the present disclosure is a display system that indicates a situation of a plurality of work devices of a production line that produces a product by sequential work through the plurality of work devices, wherein the display system comprises: a sensing module that acquires measurement information obtained by measuring states of a plurality of work units contained in a work device that is contained in the plurality of work devices; a state determination module that, based on the measurement information, determines a state of at least one work unit contained in the plurality of work units; and a display that shows a state determination result determined by the state determination module.In the display system, the display shows the status determination result of at least one work unit on a chronological screen.

[0010] Furthermore, according to one aspect of the present disclosure, a program is a program that causes a computer to execute the display procedure.

[0011] It should be noted that these general or specific aspects can be implemented using a system, a method, an integrated circuit, a computer program, or a computer-readable recording medium, such as a Compact Disc Read-Only Memory (CD-ROM), or any combination of systems, methods, integrated circuits, computer programs, and recording media.

[0014] The following describes one embodiment specifically 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, among the components in the following embodiment, those not listed in any of the independent claims are described as optional components.

[0016] Furthermore, the drawings are schematic and do not necessarily represent precise illustrations. In the drawings, the same components have the same reference symbols. [Version]<Funktionale Konfiguration: Anzeigesystem 10>

[0017] First, production system 1, which includes display system 10 according to the present embodiment, is described with reference to Fig. 1 to Fig. 3 described.

[0018] Fig. Figure 1 is a schematic diagram showing display system 10 according to the present embodiment. Fig. 2 is a block diagram, display system 10 in Fig. 1 represents. Fig. Figure 3 is a top view showing one of the production fixtures M3 to M7, which are component assembly fixtures.

[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, i.e., a substrate 13 onto which components, etc., have been mounted. Production system 1 includes production line L and display system 10.

[0020] Production line L is a production line for manufacturing the product. For example, if the product is a populated substrate, production line L is a component assembly line for assembling components onto substrate 13. Production line L comprises a plurality of production devices M1 to M9 and produces the product through the sequential operation of the plurality of production devices M1 to M9.

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

[0022] It should be noted that production system 1 can comprise not only a multiple production devices, but also, for example, just a single production device. Production devices M1 to M9 are therefore only an example.

[0023] Each of the plurality of production devices M1 to M9 comprises a plurality of work units. The plurality of work units comprises different types of work units. As in Fig. As shown in Figure 3, each work unit can, for example, consist of at least one assembly head 18, which moves and mounts a component onto substrate 13, a nozzle 19a, which holds a component, or a feeder 14a, which feeds a component. Therefore, each of the production devices M3 to M7 can simply comprise a plurality of work units. Nozzle 19a is an example of a holder.

[0024] Of the majority of production devices M1 to M9, production devices M3 to M7 have a plurality of areas E in which a workpiece (work target) can be machined. For example, each of the production devices M3 to M7 has a function for mounting a component onto substrate 13 in the majority of areas E. In the center of base 11 in each of the production devices M3 to M7, a substrate transport mechanism 12 is provided in the X-direction. The substrate transport mechanism 12 conveys the substrate 13, which is fed in from the upstream side, in the X-direction and positions and holds the substrate 13 at a location where the assembly head 18 is to perform component assembly work. Furthermore, the substrate transport mechanism 12 conveys the substrate 13, on which the component assembly work is completed, to the downstream side. A component feeder 14 is arranged on both sides of the substrate transport mechanism 12.Y-axis table 15, which includes a linear drive mechanism, is arranged at both ends of the top of base 11 in the X-direction of base 11. Support 17, which also includes a linear mechanism, is connected to Y-axis table 15 such that support 17 can move in the Y-direction. Mounting head 18 is attached to support 17 such that mounting head 18 can move in the X-direction. A plurality of nozzle units 19 are attached to mounting head 18. Y-axis table 15 and support 17 form a mechanism for moving mounting head 18 in the horizontal direction (the X-direction, the Y-direction). Using nozzle 19a of nozzle unit 19, the mechanism for moving the assembly head and assembly head 18 draw in and pick up a component from a component removal position of the feeder 14a attached to component feeder 14.The mechanism for moving the mounting head then performs component assembly work by moving mounting head 18 to a mounting position on substrate 13, which is held by substrate transport mechanism 12, and then mounting the component.

[0025] As in Fig. 1 and Fig. As shown in Figure 2, display system 10 manages the maintenance of each of the plurality of work units contained within the plurality of production devices M1 to M9 of production line L. Display system 10 monitors each of the plurality of production devices M1 to M9 in real time, which operate automatically. Therefore, display system 10 can display the status of the plurality of production devices M1 to M9 of the production line, which manufactures a product through the sequential operation of the plurality of production devices M1 to M9. For example, display system 10 monitors each of the plurality of production devices M1 to M9 in real time by receiving measurement information from each of the plurality of production devices M1 to M9, obtained by measuring the condition of the production device, thereby managing the maintenance of the production device based on the received measurement information.It should be noted that display system 10, for example, can manage the maintenance of at least one production device from the plurality of production devices M1 to M9, instead of all of the plurality of production devices M1 to M9.

[0026] Production system 1 and display system 10 were described above.

[0027] Next, a functional configuration of display system 10 is described.

[0028] Display system 10 comprises processing unit 20, memory 31, input receiver 41 and display 42. It should be noted that display system 10 can only include the acquisition module 21 of processing unit 20, input receiver 41 and display 42, and the other components are not essential.

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

[0030] In particular, processing unit 20 comprises acquisition module 21, condition determination module 22, calculation module 23, forecasting module 24 and transition module 25.

[0031] Acquisition module 21 receives 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 module 21 receives: measurement information indicating the states of the plurality of work units contained in production device M3; measurement information indicating the states of the plurality of work units contained in production device M4; measurement information indicating the states of the plurality of work units contained in production device M5; measurement information indicating the states of the plurality of work units contained in production device M6; and measurement information indicating the states of the plurality of work units contained in production device M7.Furthermore, acquisition module 21 can receive measurement information that includes the states of the majority of work units contained in production devices M1, M2, M8 and M9.

[0032] It should be noted that the acquisition module 21 can receive measurement information indicating the states of multiple work units from at least one production device among production devices M3 to M7, instead of from all production devices M3 to M7. Furthermore, the acquisition module 21 can receive measurement information from at least one of multiple work units. This measurement information could be, for example, an image captured by a camera or similar device and / or a detection result or similar from a sensor.

[0033] Here, the measurement information is information that indicates the states of work units. For example, the measurement information that indicates the states of the plurality of work units in production device M3 includes information that indicates the state of each of the one or more components that constitute the plurality of work units in production device M3. In particular, the measurement information that indicates the states of the work units contained in production device M3 includes at least: information that indicates a measurement regarding the airflow in assembly head 18; information that indicates a sliding load value of slide 19b that moves nozzle 19a; information that indicates a measurement regarding the airflow in nozzle 19a; information that indicates an image of the tip of nozzle 19a; and information regarding the component feeding accuracy of component feeding device 14.For example, the measurement information allows the user to record the condition of each of one or more work units, including the state of deterioration, wear, dirt adhesion, and misalignment of each of the work units in production device M3. For example, each of the one or more work units comprises assembly head 18, nozzle 19a, and feeder 14a. The same applies to: the measurement information encompassing the states of the work units in production device M4; the measurement information encompassing the states of the work units in production device M5; the measurement information encompassing the states of the work units in production device M6; and the measurement information encompassing the states of the work units in production device M7.The same can also apply to the measurement information, which includes the states of the work units in production devices M1, M2, M8, M9.

[0034] Condition Determination Module 22 determines the states of the plurality of work units contained in the plurality of production devices M3 to M7, based on a plurality of measurement information obtained from Acquisition Module 21. The states of the plurality of work units encompass various types of states. Condition Determination Module 22 determines the states of the plurality of work units and outputs a condition determination result indicating, for each of the plurality of work units, whether maintenance should be performed. That is, based on the measurement information indicating the states of the work units in production device M3, Condition Determination Module 22 determines the states of the work units in production device M3 and outputs a condition determination result indicating whether maintenance of the work units in production device M3 should be performed.Condition determination module 22 determines the states of the work units in production device M4 based on the measurement information indicating their states, and outputs a condition determination result indicating whether the work units in production device M4 should be serviced. Condition determination module 22 also determines the states of the work units in production device M5 based on the measurement information indicating their states, and outputs a condition determination result indicating whether the work units in production device M5 should be serviced.Condition determination module 22 determines the states of the work units in production device M6 based on the measurement information indicating their states, and outputs a condition determination result indicating whether the work units in production device M6 should be serviced. Condition determination module 22 also determines the states of the work units in production device M7 based on the measurement information indicating their states, and outputs a condition determination result indicating whether the work units in production device M7 should be serviced.

[0035] Furthermore, based on the measurement information indicating the states of the work units in production device M1, condition determination module 22 can determine the states of the work units in production device M1 and output a condition determination result indicating whether the work units in production device M1 should be serviced. Condition determination module 22 can also determine the states of the work units in production device M2 based on the measurement information indicating their states and output a condition determination result indicating whether the work units in production device M2 should be serviced.Condition Determination Module 22 can determine the states of the work units in production device M8 based on the measurement information indicating their states, and output a condition determination result indicating whether the work units in production device M8 should be serviced. Similarly, Condition Determination Module 22 can determine the states of the work units in production device M9 based on the measurement information indicating their states, and output a condition determination result indicating whether the work units in production device M9 should be serviced.

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

[0037] For example, condition determination module 22 determines the states of the work units contained in production device M3 based on the measurement information indicating the states of the work units contained in production device M3, and outputs a condition determination result indicating whether the work units contained in production device M3 have a part that requires maintenance (whether maintenance should be performed).Specifically, condition determination module 22 determines, for example, the state of contamination on feeder 14a in production device M3 based on the luminance value of feeder 14a in a captured image of an exposed tip of a pinion and a belt pocket position of feeder 14a in production device M3 and outputs a condition determination result indicating that feeder 14a in production device M3 should be serviced if feeder 14a in production device M3 is so heavily contaminated that cleaning is required.Furthermore, state determination module 22, for example, determines the displacement state of nozzle 19a contained in production device M3 based on a detection result from a pressure sensor used to detect the displacement state of nozzle 19a contained in production device M3, and outputs a state determination result indicating that maintenance of nozzle 19a, which is a working unit of production device M3, should be carried out if displacement of nozzle 19a, which is a working unit of production device M3, is made difficult to such an extent that cleaning of nozzle 19a is required.

[0038] For example, condition determination module 22 also 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, condition determination module 22 outputs a condition result indicating that maintenance should be performed on that part. Condition determination module 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, state determination module 22 stores the state determination result for each of one or more work units contained in production device M3 in memory 31. Similarly, state determination module 22 also stores the state determination result in memory 31 for each of one or more work units contained in production devices M4, M5, M6, and M7. Likewise, state determination module 22 can also store the state determination result in memory 31 for each of the one or more work units contained in production devices M1, M2, M8, and M9.

[0040] Computing module 23 calculates a maintenance interval period based on past maintenance execution time stored in memory 31. Computing module 23 stores the calculated maintenance interval period in memory 31. The maintenance interval period is, for example, the operating time of a specific work unit of production device M3, which is calculated by computing module 23 for performing maintenance on that specific work unit of production device M3.

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

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

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

[0044] Based on the number of operations previously performed by a specific work unit of production device M3, which is stored in memory 31, calculation module 23 calculates a maintenance interval count for carrying out maintenance. Calculation module 23 stores the calculated maintenance interval count in memory 31. The maintenance interval count is, for example, the number of operations to be performed by a specific work unit of production device M3 and is calculated by calculation module 23 for carrying out maintenance on that specific work unit of production device M3.The maintenance interval number is, for example, the number of operations performed by a specific work unit during a period (operating period) between a first maintenance execution time and a second maintenance execution time following the first maintenance execution time, from a plurality of maintenance execution times at which maintenance was performed in the past.

[0045] In particular, with regard to one or more work units (e.g., assembly head 18, nozzle 19a, and feeder 14a) contained in production device M3, computing module 23 retrieves a plurality of maintenance interval counts from memory 31. For example, computing module 23 retrieves the maintenance interval count for each of a plurality of operating periods in the past from memory 31. Based on the obtained plurality of maintenance interval counts in the past, computing module 23 calculates the maintenance interval count for each of the one or more work units contained in production device M3.It should be noted that Computing Module 23 can calculate the number of maintenance intervals for each of one or more work units contained in Production Device M3 by increasing or decreasing a predetermined number based on the predetermined number and the obtained number of operations performed in each of a plurality of operating periods in the past.

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

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

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

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

[0050] In the same way, computing module 23 also stores the maintenance date and time, with a small deviation, in memory 31 as an expected maintenance date and time for the given work unit of production device M4, production device M5, production device M6, and production device M7. It should be noted that computing module 23 can also store the maintenance date and time, with a small deviation, in memory 31 as an expected maintenance date and time for the given work unit of each of production devices M1, production device M2, production device M8, and production device M9.

[0051] Based on the maintenance interval period of a given work unit of production device M3 stored in memory 31, forecasting module 24 predicts a first next maintenance date and time. Based on the number of maintenance intervals for the given work unit of production device M3 stored in memory 31, forecasting module 24 predicts a second next maintenance date and time. If multiple work units are to be serviced, forecasting module 24 predicts, for each of the multiple work units to be serviced, the first next maintenance date and time based on the maintenance interval period and the second next maintenance date and time based on the number of maintenance intervals.

[0052] Forecast module 24 stores in memory 31 the first next maintenance date and time and the second next maintenance date and time that were forecast for each of one or more work units in production device M3.

[0053] Similarly, Forecasting Module 24 also forecasts the first and second next maintenance dates and times for each of the work units in Production Device M4, Production Device M5, Production Device M6, and Production Device M7, and stores these forecasted dates and times in Memory 31. It should be noted that Forecasting Module 24 can also store the first and second next maintenance dates and times forecasted for each of the work units in Production Device M1, Production Device M2, Production Device M8, and Production Device M9 in Memory 31.

[0054] Forecasting module 24 also stores in memory 31 a predicted maintenance date and time that were previously forecasted for a given work unit of production device M3. Therefore, forecasting module 24 can predict the first next maintenance date and time, and the second next maintenance date and time, for the given work unit of production device M3, taking into account the previously forecasted 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 past maintenance execution time, 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. Memory 31 is implemented, for example, as a data storage device or similar.

[0056] Transition module 25 causes a transition between a first screen displayed on display 42 and a second screen displayed on display 42 that differs from the first screen. Specifically, when input receiver 41 receives user input, transition module 25 causes the content displayed on 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] Transition module 25 initiates a transition on the production line screen to a production device screen of a production device selected from the plurality of production devices M1 to M9. Specifically, when input receiver 41 receives user input, transition module 25 causes the content displayed on display 42 to transition from the production line screen to the production device screen, or vice versa.

[0058] Input receiver 41 receives user input. For example, input receiver 41 receives user input to set multiple maintenance dates and multiple maintenance deadlines. Input receiver 41 is implemented, for example, as a touch panel, a hardware button, or similar device.

[0059] Display 42 shows a screen representing the situation of production line L. The screen displayed by display 42 includes: a production line screen representing production line L to show the status of production line L; and a determination result screen, which, using a visually distinguishable symbol, displays a status determination result indicating the status of at least one of a plurality of work units contained in a production device, selected from the status determination results indicating the statuses of the plurality of work units based on a predetermined condition.

[0060] The predetermined condition is 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 showing the state determination results of the plurality of work units as the state determination result of the single production device. Thus, if the state determination results of the plurality of work units are the same, display 42 shows a determination result screen summarizing the state determination results of the plurality of work units as the state determination result of the single production device.

[0061] The predetermined condition also stipulates 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 the one or more work units. Thus, if the state determination results of the plurality of work units are different, the display shows 42 determination result screens, each showing the individual state determination results of the plurality of work units.

[0062] Furthermore, display 42 shows a production device screen, which is distinct from a chronological screen and is a screen in which a production device has been selected from the plurality of production devices M1 to M9. Display 42 transitions from the production device screen to a chronological screen of a selected work unit. The production device screen is an example of a selection screen. The display screen can be an example of a selection screen.

[0063] Display 42 shows the production equipment screen, which classifies a number of different work units, as shown on the production line screen, by type. The production equipment screen is a screen included within the display screen and is a screen where a number of different work units are classified by type. The production equipment screen therefore allows the user to easily identify the number of different work units displayed by Display 42 and classified by type.

[0064] Display 42 shows the status determination results on the second screen, which is a chronological screen. These results indicate the states of a plurality of work units contained in the plurality of production devices M1 to M9 and selected on the selection screen. Display 42 also shows the status determination result determined for each of the different types of work units. The second screen is an example of the chronological screen.

[0065] Display 42 shows on the second screen, which is the chronological screen, only the status determination results, which include the states of a plurality of work units contained in the plurality of production devices M1 to M9 that were selected on the selection screen.

[0066] Display 42 shows a status determination result for each of the plurality of areas E in which work is performed on a workpiece by each of the plurality of production devices M1 to M9. Display 42 shows: the first screen, which includes the production line screen and the status result screen, and the second screen, which displays the status determination results of all of the plurality of work units in the selected area. The first screen can be an example of the selection screen.

[0067] Display 42 shows at least one of the first next maintenance date and time and one of the second next maintenance date and time. For example, display 42 shows at least one of the first next maintenance date and time or one of the second next maintenance date and time for each of one or more work units.

[0068] Display 42 shows the first next maintenance date and time with a small deviation or the second next maintenance date with a small deviation, based on a plurality of maintenance interval periods and a plurality of maintenance interval counts.

[0069] Such a display 42 is designed, for example, as a liquid crystal display, as an organic electroluminescence (EL) display or the like. <Monitoring list of work units>

[0070] First, the following describes, with reference to Fig. 4 a monitoring list for determining, by state determination module 22, the states of the majority of work units in production devices M3 to M7.

[0071] Fig. Figure 4 is a diagram that represents a monitoring list of work units.

[0072] As in Fig. As shown in Figure 4, state determination module 22 determines the states of the majority of work units in production devices M3 to M7 under production devices M1 to M9 based on the monitoring list. The monitoring list includes: monitored units, which indicate assembly head 18, nozzle 19a, and feeder 14a as monitoring targets and which are work units; monitored elements corresponding to the monitored units; and a description corresponding to the monitored elements. It should be noted that in Fig. 4 and the following drawings, the mounting head 18 can simply be referred to as the head.

[0073] For example, state determination module 22 determines the states of each of the plurality of monitored units, which are the plurality of work units contained in production devices M3 to M7, based on the monitored units, the monitored elements and the description.

[0074] Fig. Section 4 presents, in particular, assembly head 18, nozzle 19a, and feeder 14a as examples of the monitored units. If the monitored unit is assembly head 18, the monitored element is filter clogging and nozzle holder displacement. The description states that filter clogging is determined by measuring the flow rate of assembly head 18 at a predetermined time during the assembly of a component through assembly head 18. The description indicates that nozzle holder displacement is determined by measuring the sliding load on the holder. If the monitored unit is nozzle 19a, the monitored element is nozzle clogging and the condition of the nozzle tip. The description indicates that nozzle clogging is determined by measuring the flow rate of nozzle 19a at a predetermined time during a component intake process through nozzle 19a.The description shows that the condition of the nozzle tip is determined by taking an image of the nozzle tip section at the time of measuring a chronological change. If the monitored unit is feeder 14a, the monitored element is the feeder's feed accuracy. The description indicates that the feeder's feed accuracy is determined by estimating the position of the belt pocket at the time a pinion has completed one revolution.

[0075] In the manner described above, state determination module 22 determines the states of monitored units, that is, the states of the majority of work units contained in production devices M3 to M7, and outputs the state determination results. State determination module 22 outputs the state determination results to memory 31 for storage. State determination module 22 also outputs the state determination results to display 42, which then displays the state determination results.

[0076] The following refers to Fig. 5 a state list described, for displaying the state determination results by display 42, which shows the results of the determination of the states of the majority of work units contained in production devices M3 to M7.

[0077] Fig. Figure 5 is a diagram that represents a status list of work units.

[0078] As in Fig. As shown in Figure 5, display 42 shows a state determination result that indicates at least one of the states of a plurality of work units. That is, display 42 shows the state determination result determined by state determination module 22. Display 42 displays the state determination result using different colors.

[0079] Specifically, the condition list includes in Fig. 5: 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.

[0080] The status of a work unit, for example, encompasses a variety of states such as "Unmeasured," "Normal," "Semi-Normal," "Maintenance Warning," and "Anomalous." The display content, for example, encompasses a variety of content such as "Unmeasured," "Normal," "Semi-Normal," "Warning," and "Anomalous." The color, for example, encompasses a variety of 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). The "Normal" state is a state that requires no maintenance. The "Semi-Normal" state is a state in which the unit is within the maintenance timeframe, but sufficient time remains in the schedule.The "warning" condition is a state in which the system is in the second half of the maintenance 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.

[0081] For example, if the status and display content of a work unit is "Unmeasured," the color is solid. As a description, solid color indicates an initial state or a state in which the maintenance recording button is pressed.

[0082] When the state and display content of a work unit are "Normal", the color is green. Green indicates that the work unit's state is within normal specifications.

[0083] When the condition 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 represents a state where a maintenance threshold has been reached.

[0084] When a work unit's status is "Maintenance Warning" and the display content is "Warning," the color is yellow. The color yellow indicates that the work unit's status is within normal specifications and that a maintenance warning threshold has been reached.

[0085] If the state and display content of a work unit are "anomalous," the color is red. As a description of the color, red indicates that the work unit's state is outside of normal specifications.

[0086] It should be noted that in Fig. 5 etc. The states of the work units can be indicated by colors, but the present disclosure is not limited to this. The states of the work units can, for example, be indicated by symbols such as a circle, a triangle, and a square. Alternatively, the states of the work units can also be indicated by letters such as A, B, and C. <Anzeigebildschirm und chronologischer Bildschirm>

[0087] The following describes the display screen with reference to Fig. 6 described.

[0088] Fig. Figure 6 is a diagram that represents the state of production line L.

[0089] Display 42 shows the display screen. The display screen comprises: a production line screen representing production line L; a results screen located within the production line screen; and a production equipment screen classifying a number of different work units according to type. The production line screen and the results screen are contained within the first screen.

[0090] For example, a plurality of determination result screens, representing a plurality 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 multiple result screens representing multiple work units located on the rear (R) and multiple result screens representing multiple work units located on the front (F). Some of the result screens display an "H" symbol, indicating a mounting head; an "N" symbol, indicating a nozzle; and an "F" symbol, indicating a feeder, as examples of work units. Other result screens display an "OK" symbol, indicating that all components are in a normal condition.

[0091] The symbols displayed on the determination result screens indicate a plurality of different states, such as "Unmeasured" state, "Normal" state, "Semi-normal" state, "Maintenance warning" state, and "Abnormal" state.

[0092] Of the majority of the test result screens arranged on the back panel R, the leftmost screen (table) displays yellow "Warning" symbols for "H" and "N" and a yellow-green "Semi-normal" symbol for "F". The second screen from the left displays a yellow-green "Semi-normal" symbol for "H" and green "Normal" symbols for "N" and "F". The third, fourth, and sixth screens from the left each display a green "Normal" symbol for "OK". The fifth screen from the left displays a green "Normal" symbol for "H" and yellow-green "Semi-normal" symbols for "N" and "F".

[0093] Of the majority of the test result screens arranged on the front panel F, the leftmost screen displays a green symbol indicating "Normal" for the symbol "H" and yellow-green symbols indicating "Semi-normal" for the symbols "N" and "F". The second screen from the left displays green symbols indicating "Normal" for the symbols "H" and "N", and a yellow-green symbol indicating "Semi-normal" for the symbol "F". The third, fourth, fifth, and sixth screens from the left each display a green symbol indicating "Normal" for the symbol "OK".

[0094] It should be noted that in each of the majority of the determination result screens arranged on the rear R and each of the majority of the determination result screens arranged on the front F, the most unfavorable condition among the conditions of the majority of assembly heads is indicated by a colored symbol, the most unfavorable condition among the conditions of the majority of nozzles by a colored symbol, and the most unfavorable condition among the conditions of the majority of feeders by a colored symbol.

[0095] 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. The production device screen displays content that corresponds to the first screen.

[0096] The production equipment screen displays the "Status" of a work unit, the "Equipment Name" of the work unit, a "Table" displaying a determination result screen, the "Position" of the work unit, the "Unit" that is the work unit, the "Type" that specifies the work unit, the "Monitoring Target" of the work unit, and the "Time" at which the status of the work unit was measured.

[0097] In the "Unit Type" section on the production equipment screen in Fig. 6. At least one of the symbols "Head", "Nozzle", or "Feed" can be selected. By selecting at least one of the symbols "Head", "Nozzle", or "Feed", the corresponding "Unit" is displayed on the production device screen. Therefore, it is possible to display multiple different work units on the production device screen, classified by type.

[0098] In the "Display Priority" section, which appears on the production equipment screen, you can select either a "Condition" icon to display components in ascending order of their conditions, starting with the component in the worst condition, or an "Equipment Number" icon to display components in order of their equipment names. Selecting either the "Condition" or "Equipment Number" icon displays "Units" on the production equipment screen sorted by the selected icon. In other words, Transition Module 25 causes the content displayed on the production equipment screen to transition according to the icon selected by the "Condition" or "Equipment Number" icon.

[0099] On the production equipment screen in Fig. For example, the symbols "Head", "Nozzle", "Feed", and "Status" are selected. In this case, for example, in the first line of the production equipment screen, "Status" displays a "Warning", "Device Name" displays NPM-WX-1, "Table" displays 1, "Position" displays "5", "Unit" displays "Head", "Type" displays 16-Nozzle Head, "Monitoring Target" displays "Filter Clogging", and "Time" displays 2022 / 03 / 07 07:57. As another example, in the second line of the production equipment screen, “Status” shows a warning, “Equipment Name” shows NPM-WX-1, “Table” shows 1, “Position” shows 34, “Unit” shows nozzle, “Type” shows 230, “Monitoring Target” shows nozzle clogging, and “Time” shows 2022 / 03 / 08 13:40.

[0100] Next, with reference to Fig. 7 describes the second screen, which shows the status determination results for each element of the "monitoring target" displayed on the screen in Fig. Figure 6 is shown. Fig. 7. The horizontal axis displays past records (month and date) chronologically, showing the progress of the unit's condition change, and the vertical axis represents the rate of condition change. Although the horizontal axis displays month and date, it can also display date and time. The vertical axis indicates the condition of a work unit; a range of 0% to less than 80% indicates "Normal," a range of 80% to less than 100% indicates "Semi-Normal," a range of 100% to less than 120% indicates "Warning," and 120% or higher indicates "Anomalous." Each of the numbers appended to the chronological graph displayed on the second screen indicates the time at which one or more components of a work unit were in a most unfavorable condition.

[0101] Fig. Figure 7 is a diagram that displays status determination results for each "monitoring target" on chronological screens. The top screen of the second screen in Fig. Screen 7 is a screen that displays "units" in which a filter blockage is listed as a "monitoring target". Fig. 6 has occurred. The upper screen shows, as an example, “units” 1F, 1R, 2F, 2R, 3F, 3R, 4F, 4R, 5F, 5R, 6F and 6R. Fig. Figure 7 represents an example case where "unit" is nozzle unit 19. The upper screen is an example of the chronological screen.

[0102] 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 a "monitoring target". The lower left screen shows, as an example, the 1nth to 16nth nozzles 19a intended for "unit" 1F. The lower left screen is an example of a chronological display.

[0103] The lower right screen of the second screen in Fig. Screen 7 displays the status determination result of the 9nth nozzle 19a out of 16 nozzles 19a in chronological order. The lower right screen is an example of a chronological screen.

[0104] For example, if the user wants to display "units" in which a filter blockage has occurred and enters "units" in which a filter blockage has occurred via input receiver 41 on the production device screen of the display screen in Fig. Selecting 6 causes transition module 25 to 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 view the top screen in Fig. 7. Record the conditions of a plurality of “units” in which a filter blockage has occurred.

[0105] If the user then selects input receiver 41 from the majority of those on the upper screen in Fig. If the "Unit" 1F is selected from the 7 displayed "Units", display 42 appears 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 see on the lower left screen in Fig. 7 record the states of the 1nth to 16nth nozzles 19a contained in “unit” 1F.

[0106] If the user then selects the 9nth nozzle 19a from the states of the 1nth to 16nth nozzles 19a, which are displayed on the lower left screen in Fig. As shown in 7, if 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 condition in the hourly graph. Accordingly, the user can access the lower right screen in Fig. 7. Read the condition of the 9nth nozzle contained in “unit” 1F, so that a detailed analysis etc. becomes possible.

[0107] It should be noted that transition module 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.

[0108] Accordingly, the in Fig. 6 and Fig. The seven displayed screens allow the user to easily understand the states of the work units contained in production devices M3 to M7. Furthermore, the user can view details of the work unit states and the state of one or more components contained within the work units. <Bildschirme von Zustandserkennungsergebnissen>

[0109] With reference to Fig. 8 to Fig. 11. In the following, a condition check screen, a head inspection screen, a nozzle inspection screen, and a feed inspection screen are described, which show condition determination results obtained by determining the states of the majority of work units in the production devices M3 to M7.

[0110] Fig. Figure 8 is a diagram representing a condition check screen showing condition determination results. Fig. Figure 9 is a diagram representing a head inspection screen showing condition assessment results. Fig. Figure 10 is a diagram representing a nozzle inspection screen showing condition assessment results. Fig. Figure 11 is a diagram representing a feed inspection screen showing condition assessment results.

[0111] As in Fig. As shown in Figure 8, display 42, for example, shows a condition check screen (or condition check image) from which condition determination results from work units have been extracted. The condition check screen displays a plurality of tabs (or icons). One of the plurality of tabs includes a "Maintenance - Condition Check" item for performing maintenance on one or more work units. The "Maintenance - Condition Inspection" condition check screen displays a condition determination result for each of the plurality of areas E. Condition check screen in Fig. Figure 8, for example, shows a status determination result for each of two areas, "Front" and "Rear." The status determination result shows, for example, "Target Unit," which indicates a unit of work, and "Status," which corresponds to the "Target Unit." For example, "Target Unit" shows a "16-Nozzle Head" symbol, a "Nozzle" symbol, and a "Feed" symbol for each of the two areas. For example, "Status" for "Front" shows a yellow-green symbol for "Semi-Normal" for the "16-Nozzle Head" symbol, a yellow symbol for "Warning" for the "Nozzle" symbol, and a red symbol for "Anomalous" for the "Feed" symbol. For example, “Status” for “Rear” shows a monochrome symbol “-” for the “16-nozzle head” symbol, a yellow “Warning” symbol for the “Nozzle” symbol, and a red “Anomalous” symbol for the “Feed” symbol.

[0112] The status check screen displays colored icons indicating the status of multiple work units. For example, for "16-nozzle head," an icon in a color corresponding to nozzle 19a, which is in the worst-case condition of the 16 nozzles 19a, is displayed.

[0113] If the user then, for example, selects "16-nozzle head" on the "front" of the screen... Fig. If the condition check screen shown in 8 is selected, display 42 shows a head inspection screen (head inspection image) which is in Fig. 9 is shown. Display 42 can, for example, switch between the first screen and the second screen. That is, display 42 can switch between the one shown in Fig. 8 shown condition check screen and the one in Fig. Switch between the 9 head inspection screens shown. If the condition check screen is an example of the first screen, the head inspection screen is an example of the second screen. If the head inspection screen is an example of the first screen, the condition check screen is an example of the second screen.

[0114] The head inspection screen displays colored symbols indicating the states of multiple nozzles 19a as the states of working units. The head inspection screen also displays "POS **" symbols indicating the positions of multiple nozzles 19a. "**" represents any number. As an example, Fig. The 9 symbols “POS1” to “POS16” represent the positions of 16 nozzles 19a, as well as symbols located next to symbols “POS1” to “POS16” that indicate the states of nozzles 19a in color.

[0115] Furthermore, the head inspection screen displays symbols indicating filter clogging and holder displacement as the specific conditions of the majority of nozzles 19a. The head inspection screen is displayed in such a way that the user can identify the positions of the nozzles 19a where filter clogging and holder displacement have occurred for the majority of the nozzles 19a.

[0116] For example, the head inspection screen in Fig. 9 symbols, which indicate the status of nozzles 19a at POS1 to POS16 with regard to filter clogging by means of color.

[0117] If the user then, for example, selects "nozzle" on "front" on the in Fig. When the status check screen shown in step 8 is selected, display 42 shows the information in Fig. The nozzle inspection screen (nozzle inspection image) shown in 10 is displayed. Display 42 can be selected from the one shown in Fig. The status check screen shown in section 8 and the one in Fig. Switch between the nozzle inspection screens shown in Figure 10. If the condition check screen is an example of the first screen, the nozzle inspection screen is an example of the second screen. If the nozzle inspection screen is an example of the first screen, the condition check screen is an example of the second screen.

[0118] The nozzle inspection screen displays colored icons indicating the status of most nozzles 19a as working units. The nozzle inspection screen also displays "F**" icons indicating the changeover positions of most nozzles 19a. Fig. For example, 10 represents symbols “F11” to “F18” and “F21” to “F28”, which indicate the changeover positions of nozzles 19a, and symbols located next to symbols “F11” to “F18” and “F21” to “F28”, which indicate the states of nozzles 19a by color.

[0119] Furthermore, the nozzle inspection screen displays symbols indicating nozzle clogging and tip condition as the specific states of the majority of nozzles 19a. The nozzle inspection screen is displayed in such a way that the user can identify the nozzle clogging and tip condition of each of the majority of nozzles 19a and the positions of the majority of nozzles 19a.

[0120] The nozzle inspection screen in Fig. Figure 10 shows, for example, symbols that indicate the condition of nozzles 19a in positions F11 to F18 and F21 to F28 with regard to nozzle clogging by means of color.

[0121] If the user then selects, for example, "Feed" under "Front" on the in Fig. When the status check screen shown in step 8 is selected, display 42 shows the information in Fig. The feed inspection screen (feed inspection image) shown in Figure 11 is displayed. Display 42 can be switched between the one shown in Figure 11. Fig. The status check screen shown in section 8 and the one in Fig. Switch to the feed inspection screen 35 shown in Figure 11. If the condition check screen is an example of the first screen, the feed inspection screen is an example of the second screen. If the feed inspection screen is an example of the first screen, the condition check screen is an example of the second screen.

[0122] The feeder inspection screen displays colored symbols indicating the status of the majority of feeders 14a as the status of work units. The feeder inspection screen also displays numerical symbols indicating the status of the majority of feeders 14a. Fig. For example, 11 represents numerical symbols indicating 17 feeds 14a, and symbols located next to the numerical symbols that color-code the states of feeds 14a.

[0123] The feeder inspection screen also displays icons indicating component feeding accuracy as the specific states of the plurality 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 plurality of feeders.

[0124] The feed inspection screen in Fig. Figure 11 shows, for example, symbols that indicate the component feeding accuracy in each of the plurality of feeders 14a by means of color.

[0125] As described above, in the present embodiment it is possible to display the states of the working units in each of the plurality of areas E, that is, the state of each of the components contained in the working units, as in the Fig. The condition check screen shown in Figure 8 allows the user to easily identify the condition of work units that require maintenance. Furthermore, because the condition check screen displays the condition of the component in the worst state, the user can easily see if any component requires maintenance.

[0126] When the user selects the "16-nozzle head" symbol via input receiver 41, which is a work unit listed as a "target unit" on the condition check screen, transition module 25 causes a transition from the condition check screen to the head inspection screen, and display 42 then shows the head inspection screen. Accordingly, the user can view the status of assembly heads 18, which are work units, and the maintenance times of the assembly heads 18 on the head inspection screen.

[0127] When the user selects the "nozzle" symbol via input receiver 41, which is a work unit listed as a "target unit" on the condition check screen, transition module 25 causes a transition from the condition check screen to the nozzle inspection screen, and display 42 then shows the nozzle inspection screen. Accordingly, the user can, for example, view the status of nozzles 19a, which are work units, and the maintenance times of nozzles 19a on the nozzle inspection screen.

[0128] When the user selects the "Feeder" symbol via input receiver 41, which is a work unit listed as a "Target Unit" on the condition check screen, transition module 25 causes a transition from the condition check screen to the feeder inspection screen, and 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>

[0129] Next, advantageous effects of display system 10, the display device, the display method, and the program according to the present embodiment will be described.

[0130] As described above, display system 10, according to the present embodiment, shows the status of a plurality of production devices (for example, M1 to M9) of a production line that manufactures a product through the sequential operation of the plurality of production devices. Display system 10 comprises: a detection module 21, which receives measurement information obtained by measuring the states of a plurality of work units within a production device contained within the plurality of production devices; a state determination module 22, which determines a state of at least one work unit contained within the plurality of work units based on the measurement information; and a display 42, which shows a state determination result determined by the state determination module 22. Display 42 shows the state determination result of the at least one work unit on a chronological screen.

[0131] Accordingly, display 42 on the visually differentiated chronological screen can show the determination result indicating the state determination result, which specifies the state of at least one work unit selected under a given condition. For example, display 42 on the chronological screen can show the state of a work unit that is in an unfavorable state among a plurality 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 reducing the number of icon displays; that is, display 42 can reduce the amount of information displayed on the screen, thereby improving visibility for the user.

[0132] Therefore, according to the embodiment, display system 10 enables the user to easily perceive the states of work units of a production device.

[0133] Furthermore, a display device according to the present embodiment shows the status of a plurality of production devices in a production line that manufactures a product through the sequential operation of the plurality of devices. The display device comprises: a detection module 21, which receives measurement information obtained by measuring the states of a plurality of work units contained within a production device; a state determination module 22, which determines the state of at least one work unit contained within the plurality of work units based on the measurement information; and a display 42, which shows a state determination result determined by the state determination module 22. The display 42 shows the state determination result of the at least one work unit on a chronological screen.

[0134] This advertisement achieves the same beneficial effects as those described above.

[0135] Furthermore, a display method according to the present embodiment is a display method for indicating the status of a plurality of production devices in a production line that produces a product through sequential work by the plurality of production devices. The display method comprises: acquiring measurement information by acquisition module 21, obtained by measuring the states of a plurality of work units contained in a production device that is itself contained in the plurality of production devices; determining, by state determination module 22, a state of at least one work unit contained in the plurality of work units, based on the measurement information; and displaying a state determination result, determined by state determination module 22, on display 42.Display 42 shows the status determination result of at least one work unit on a chronological screen (the top screen, the bottom left screen, and the bottom right screen in . Fig. 7).

[0136] This display method achieves the same beneficial effects as those described above.

[0137] Furthermore, a program according to the present embodiment is a program that causes a computer to execute the display procedure.

[0138] This program also achieves the same beneficial effects as those described above.

[0139] As described above, display 42 in display system 10 according to the present embodiment also displays: a selection screen (a production device screen) which is different from the chronological screen and is a screen for selecting the at least one work unit; and the chronological screen of the at least one work unit that was selected on the selection screen by transitioning from the selection screen.

[0140] Accordingly, in response to a user selecting a desired work unit on the selection screen, display 42 can show a chronological screen of that work unit by transitioning from the selection screen. This allows the user to easily grasp the status of the desired work unit.

[0141] Furthermore, as described above, display 42 in display system 10 according to the present embodiment shows on the chronological screen status determination results of a plurality of work units that were selected on the selection screen from the plurality of work units contained in the one production device.

[0142] Accordingly, display 42 can show the status determination results of all selected production devices. Therefore, the user can record the status of all selected production devices as historical data.

[0143] Furthermore, as described above, display 42 in display system 10 according to the present embodiment shows on the chronological screen only the status determination results of a plurality of work units that were selected on the selection screen.

[0144] Accordingly, since display 42 can only show the status determination results of the majority of the selected work units, it is possible to prevent an increase in the amount of information displayed on display 42. Therefore, the user can easily record only the status determination results of the majority of the selected work units as past records.
