In this system, a user selects a desired display screen from a list of multiple plant-related display screens (graphic screens, trend screens, etc.), and arranges the selected display screen in an arbitrary layout on the display unit. By storing the layout in the storage unit, it is possible to display a monitoring control screen according to the layout desired by the user (that is, the layout stored in the storage unit).

In the technique disclosed in Japanese Patent Application Laid-open No. 2011-118493, in order to display a desired screen, the user selects a desired display screen from a list of a plurality of display screens and arranges it on the display unit in advance. Here, in a production facility equipped with a production line that produces circuit boards, there may be many subdivided operational statuses that the user wants to check, and there may also be many display screens necessary to check these many operational statuses. . For this reason, if the technology of Japanese Patent Application Laid-open No. 2011-118493 is adopted for a display device that displays the operating status of such production equipment, a large number of layouts will be created corresponding to each of the multiple operating statuses that are desired to be displayed. When a large number of layouts are created, there is a problem in that when a user wants to display a specific operating status, it is cumbersome to select and display a layout corresponding to the specific operating status from among the many created layouts. This specification provides a technology for displaying the operating status of production equipment including a production line that produces substrates, which allows a user to easily display a display screen according to the operating status of the production equipment.

Then, when the user inputs an instruction to select one of the display levels, a display screen that displays one or more detection items that are previously associated with the display level from among the acquired detection items is displayed on the display unit. be done. That is, the operating status (detection items) that the user wants to display is hierarchically divided into a plurality of display levels, and one or more detection items are associated with each of the plurality of display levels. Therefore, by simply selecting a display level, the user can narrow down the detection items to those associated with the selected display level, and the user can easily grasp the desired operating status. For example, when an instruction to select a display level for displaying an error state is input, detection items corresponding to the error state are displayed. In this way, in this display device, detection items that are classified in advance according to the selected display level are displayed on the display section. That is, by simply inputting an instruction to select a preset display level, the user can confirm detection items corresponding to the display level.

In one embodiment of the present technology, each of the plurality of detection items may be associated with a partial image that displays the detection item. The display screen may be composed of one or more partial images associated with one or more detection items to be displayed.

In such a configuration, a display screen composed of partial images displaying detection items to be displayed is displayed. Therefore, visibility is improved.

In an embodiment of the present technology, the display device further includes a layout setting section that can be operated by a user and that can input instructions for setting a layout of one or more of the partial images that constitute the display screen. Good too. The control unit may display the display screen on which the partial images are arranged in a layout set by the layout setting unit on the display unit.

According to such a configuration, the user can input an instruction to set the layout of the display screen corresponding to a certain display level. For example, the user can set the display screen displayed on the display unit to a layout desired by the user by inputting an instruction to change the arrangement of partial images in a preset display screen layout.

In one embodiment of the present technology, the display device includes a display item setting section that can be operated by a user and that can input an instruction for setting one or more detection items to be associated with the display level for each display level. Further provision may be made. When an instruction to select a specific display level is input from the display level selection section, the control section selects one or more detections associated with the specific display level set in the display item setting section. A display screen displaying items may be displayed on the display section.

According to such a configuration, the user can input an instruction to set a detection item to be associated with a certain display level. For example, among the detection items that are pre-corresponding to a certain display level, detection items that are of low importance to the user may be deleted from the display screen, or detection items that are not pre-corresponding to the display level but are of high importance to the user may be deleted from the display screen. It is possible to make a new correspondence with the display level. That is, there is a high degree of freedom in setting detection items to be displayed on the display section.

In one embodiment of the present technology, the production facility may include multiple production lines. The display device may further include a production line selection section that can be operated by a user and input an instruction to select one of the plurality of production lines. The acquisition unit may be capable of acquiring, for each of the plurality of production lines, a plurality of detection items indicating the operating status of the production line. The display level selection section may select the display level for the production line selected by the production line selection section. The control unit may display the display screen for the production line selected by the production line selection unit on the display unit when the display level is selected by the display level selection unit.

According to such a configuration, in a production facility including a plurality of production lines, it is possible to select a display level for a production line whose operating status is to be checked. Therefore, the operating status of the production line to be checked can be easily displayed, and only the display screen corresponding to the display level of the selected production line is displayed on the display section, so visibility is improved.

(Example 1)
Hereinafter, a substrate production system 10 according to a first embodiment will be described with reference to the drawings. As shown in FIG. 1, the substrate production system 10 includes a production facility 12 having a plurality of production lines 20a, 20b, and 20c, and a display device 14 that displays the operating status of the production facility 12. Although not shown, the display device 14 is connected to mounting-related machines 22 and 24 that constitute each production line 20a to 20c. Each of the production lines 20a to 20c is composed of a component mounting machine 22, a printing machine 24, etc., and produces circuit boards 26a to 26c by mounting components on the boards being transported. Note that the production facility 12 does not need to have multiple production lines, and may have only a single production line.

As shown in FIG. 2, the display device 14 includes a display section 30, an operation section 32, an acquisition section 34, and a control section 36. The display unit 30 is a display for displaying various information, icons corresponding to display levels (described later), display screens corresponding to the display levels (described later), and the like. The display level is information for indicating the operating status of each production line 20a to 20c (for example, whether the operation of each production line 20a to 20c is normal or abnormal), and there are multiple display levels depending on the operating status. The display level of is set in advance. In this embodiment, the display level indicates any one of an Error level, a Warning level, an Info level, and a Success level.

The Error level indicates that an event has occurred in which the production lines 20a to 20c have stopped operating. Examples of such events include, for example, a situation where the production equipment 12 is stopped due to a communication error with a server (not shown) that controls the operations of all the production lines 20a to 20c. The Warning level indicates that an event has occurred that significantly reduces the productivity of the production lines 20a to 20c. The event may be, for example, when the component mounting unit (e.g., mounting head, suction nozzle, etc.) of the component mounting machine 22 makes a mistake in mounting components onto the circuit board at a predetermined frequency or more, and the general equipment Examples include situations where overall equipment efficiency (OEE) is significantly reduced. The Info level does not significantly affect the productivity of the production lines 20a to 20c, but indicates that an event such as a minor defect has occurred. Examples of such events include, for example, a situation where the OEE slightly decreases due to a component shortage occurring in a component supply unit (component feeder, etc.). The Success level indicates that the production lines 20a to 20c are operating normally. In this way, in this embodiment, the operating status of the production lines 20a to 20c is classified into one of the four levels described above, and in the display processing described below, the operating status is pre-corresponded to the classified display level. Information is displayed on the display section 30.

The operation unit 32 accepts input instructions from the user. A user can input various instructions to the display device 14 by operating the operation unit 32. The display section 30 and the operation section 32 function together as a so-called touch panel. However, the operation section 32 may be configured by a keyboard, a pointing device, etc., and may be provided separately from the display section 30.

The acquisition unit 34 acquires a plurality of detection items indicating the operating status of the production lines 20a to 20c. Examples of the detection items include the operating status of the server described above, the operating status of each production facility 12, the operating status of the component mounting unit and the component supply unit, and the production status of circuit boards. Each detection item is associated in advance with the display level described above, depending on the situation at the time of acquisition. For example, when a situation in which the production equipment 12 is stopped is acquired as a detection item and a server communication error has occurred, the detection item is associated with the Error level. For example, when the operating status of a component mounting unit is acquired as a detection item, if component mounting errors occur more than a predetermined frequency, the detection item is associated with the Warning level, and component mounting errors are detected. If the frequency is less than the predetermined frequency, the detected item is associated with the Success level. For example, when acquiring the operating status of a component supply unit as a detection item, if a component is out of stock, the detection item is associated with the Info level, and if the component is correctly set, the corresponding detection item is associated with the Info level. Detection items are associated with success levels. In this manner, in the display device 14, depending on the state of the detection item acquired by the acquisition unit 34, the detection item is associated in advance with one of the display levels.

The control unit 36 is configured by a computer. The control unit 36 controls the processing of each unit 30, 32, and 34. For example, the control unit 36 causes the display unit 30 to display a predetermined display screen, and causes the acquisition unit 34 to acquire the operating status of each production line 20a to 20c.

Next, with reference to FIG. 3, a process in which the display device 14 displays the operating status of each production line 20a to 20c on the display unit 30 will be described. The process in FIG. 3 is individually executed for each of the production lines 20a to 20c when the production equipment 12 starts operating (that is, when production of circuit boards starts). The process in FIG. 3 is executed in the same way for each of the production lines 20a to 20c, so below, a case will be described in which the process in FIG. 3 is executed for the production line 20a.

When the production equipment 12 starts operating, the control unit 36 acquires the operating status of the production line 20a in S10. Specifically, as described above, the operating status of the server that controls all operations of the production line 20a, the operating status of each production equipment 12, the operating status of each component mounting machine 22, etc. (i.e., component mounting unit, Obtain the operating status of component supply units) and the production status of circuit boards.

After S12, the control unit 36 determines which display level the acquired detection item is associated with. In S12, the control unit 36 determines whether or not there is a detection item associated with the Error level among the acquired detection items. For example, if the detection items include a detection item indicating that a server communication error has occurred, the control unit 36 determines that the detection item is associated with the Error level, and in step S14 Proceed to. Then, as shown in FIG. 4, in S14, the control unit 36 displays an icon I1 corresponding to the Error level on the display unit 30 along with an image B1 showing the production line 20a. On the other hand, if the detection item associated with the Error level is not included, the process advances to S16.

In S16, the control unit 36 determines whether or not there is a detection item associated with the warning level among the acquired detection items. For example, if the detection items include a detection item indicating that mounting errors in the component mounting unit occur more than a predetermined frequency, the control unit 36 determines whether the detection item is associated with the warning level. It is determined that it is, and the process proceeds to S18. Then, the control unit 36 displays an icon corresponding to the warning level on the display unit 30 in S18. On the other hand, if the detection item associated with the warning level is not included, the process advances to S20.

In S20, the control unit 36 determines whether there is a detection item associated with the info level among the acquired detection items. For example, if the detection items include a detection item indicating that the component supply unit is out of parts, the control unit 36 determines that the item is associated with the info level, Proceed to S22. Then, the control unit 36 displays an icon corresponding to the info level on the display unit 30 in S22. On the other hand, if the detection item associated with the info level is not included, the control unit 36 displays an icon corresponding to the success level on the display unit 30 in S24.

In S26, the control unit 36 determines whether an instruction to select a display level has been input. For example, when the user touches the icon I1 corresponding to the Error level shown in FIG. 4, the process advances to S28. If the instruction to select a display level has not been input, the control unit 36 returns to S10. That is, the control unit 36 repeats the processes of obtaining the operating status of the production line 20a (S10) and determining the display level to be displayed (S12 to S24) until receiving an instruction input from the user. Note that the process in S26 is an example of the process executed by the "display level selection section."

When the control unit 36 receives the input of the instruction to select the display level, the control unit 36 displays the display screen on the display unit 30 in S28. Specifically, upon receiving an input to select the icon I1, the control unit 36 displays a display screen S1 on the display unit 30 that displays detection items associated with the Error level, as shown in FIG. On the display screen S1, the operating status of the server (situation in which a communication error occurs), which is a detection item associated with the Error level, is displayed as a partial image P1 that displays the detection item. Furthermore, if there are detection items associated with the Error level other than server communication errors, partial images P2 and P3 corresponding to the detection item are displayed for each detection item. That is, the control unit 36 displays the display screen S1 composed of the plurality of partial images P1 to P3 on the display unit 30 as a screen showing the operating status of the production line 20a. As shown in FIG. 5, the partial images P1 to P3 include graphs, tables, etc. showing the operating status. In this way, the operating status of the production line 20a is displayed on the display unit 30. After executing S28, the control unit 36 ends the series of processing.

Note that, as described above, the display process in FIG. 3 is executed individually for each of the production lines 20a to 20c. Therefore, as shown in FIG. 4, for the production lines 20b and 20c, together with the images B2 and B3 showing the production lines 20b and 20c, the icons I2 and I3 corresponding to the display level according to the situation of the acquired detection items are displayed. is displayed on the display section 30. By touching the icons Ib and Ic, the user can display a display screen showing the operating status of the production lines 20b and 20c, similar to the display screen S1 of the production line 20a.

As described above, in this embodiment, when the production equipment 12 starts operating, the control unit 36 causes the acquisition unit 34 to acquire a plurality of detection items indicating the operating status of the production lines 20a to 20c. Then, the control unit 36 determines the display level to which each of the plurality of detection items is associated, and causes the display unit 30 to display an icon corresponding to the display level. When the user inputs an instruction to select one of the displayed icons, a display screen showing detection items corresponding to the display level is displayed. In this manner, in this embodiment, detection items that are classified in advance according to the selected display level are displayed. In other words, the user can check the detected items (operating status) corresponding to the display level by simply inputting an instruction to select the displayed display level from a plurality of preset display levels. .

(Example 2)
In the first embodiment described above, when an icon corresponding to a certain display level is selected, a display screen showing detection items previously associated with the display level is displayed on the display unit 30. In contrast, in the second embodiment, the user can set detection items associated with each display level for each display level. That is, by operating the operation unit 32, the user can set detection items to be associated with a certain display level. This setting is performed separately from the display processing shown in FIG. 3.

For example, in Example 1, the detection item indicating that mounting errors by the component mounting unit occur more than a predetermined frequency is associated with the Warning level, but some users may have different importance levels for the detection item. There may be cases where it is not accurate. In this embodiment, in such a case, the user can exclude from the Warning level a detection item that indicates that a mounting error occurs more than a predetermined frequency. In this case, the user may be able to input an instruction to associate the detection item with the Info level or the Success level. With this setting, even if mounting errors occur more than a predetermined frequency, an icon corresponding to the Info level or Success level will be displayed on the display unit 30 instead of an icon corresponding to the Warning level. Ru. For example, in the first embodiment, the detection item indicating that the component supply unit is out of parts is associated with the Info level, but depending on the user, the importance of the detection item may be relatively high. could be. In this embodiment, in such a case, the user can input an instruction to change the display level corresponding to the detected item indicating that a component is out of stock, from the Info level to the Error level, for example. With this setting, when parts are out of stock, an icon corresponding to the Error level is displayed on the display unit 30. In this manner, in this embodiment, it is possible to change the correspondence relationship set in advance between the display level and the detection item. That is, the user can freely set the detection items to be displayed when a certain display level is selected.

Further, in the first embodiment, the display screen corresponding to a certain display level is composed of a plurality of preset partial images. In contrast, in this embodiment, the layout of the partial images (the number, type, arrangement, size, etc. of partial images) constituting the display screen displayed on the display unit 30 can be set by the user. . That is, by operating the operation unit 32, the user can set the layout of the partial images that make up the display screen. This setting is performed separately from the display processing shown in FIG. 3.

For example, if the detected item is the production status of circuit boards, multiple partial images may be used to display the detected item, such as the production speed of the circuit boards, the progress rate of the production plan, the yield rate of the produced circuit boards, etc. may exist. Therefore, when the production status of a circuit board is acquired as a detection item, the detection item can be associated with a plurality of partial images. In this embodiment, in such a case, the user can set the layout of the partial image (that is, the layout of the display screen) that displays the production status of the circuit board. For example, as shown in FIG. 6, the user selects a partial image that he wants to display on the display screen S2 that displays the production status of circuit boards from a candidate group G that includes a plurality of partial images P4 to P8, and freely arranges the partial image. can do. FIG. 6 shows, as an example, a mode of arranging the partial image P4 (eg, drag and drop). In this manner, in this embodiment, a desired partial image can be selected from the plurality of partial images P4 to P8 that display the production status of circuit boards, and the layout of the display screen S2 can be freely set.

(Modified example)
In each of the embodiments described above, if the production equipment 12 has a relatively large number of production lines, a screen may be displayed for inputting an operation to select a production line whose operating status is to be displayed. For example, after S10 in FIG. 3, as shown in FIG. 7, along with images Ba to Bh showing the production lines 20a to 20h, selection images Ca to Ch for selecting each of the production lines 20a to 20h are displayed. , it may be configured such that an operation for selecting one of the production lines can be input. For example, when the control unit 36 receives an input operation for selecting the production line 20a (touching the selection image Ca by the user), only the image B1 shown in FIG. 4 may be displayed on the display unit 30. With such a configuration, when there are a large number of production lines, each production line can be displayed as a list, thereby improving visibility.

Further, in FIG. 4 of the above-described embodiment, only the icon corresponding to one display level was displayed for each production line 20a to 20c. However, icons corresponding to all display levels may be displayed, or icons corresponding to some display levels may be displayed. For example, in the production line 20a, when detection items associated with each of the Warning level, Info level, and Success level are acquired, as shown in FIG. 8, the icon I2 corresponding to the Warning level is displayed, and more Icons I3 and I4 corresponding to the Info level and Success level, which have a low degree of urgency, may also be displayed on the display unit 30.

In addition, in the above embodiment, as shown in FIG. 9, when the display screen S1 is displayed, icons corresponding to unselected display levels (in FIG. 9, icons corresponding to display levels other than the Error level) are displayed. icons I2, I3, I4) may be displayed. With such a configuration, it is possible to easily transition to a display screen corresponding to another display level.

Further, the display device 14 is not limited to a single device, and may be configured by a plurality of devices. For example, a plurality of separate devices may function as each of the display section 30, the operation section 32, the acquisition section 34, and the control section 36.

Further, a plurality of display units 30 may be provided. For example, the display device 14 may include a plurality of display sections 30 assigned to each worker. With such a configuration, each of the display screens corresponding to different display levels can be checked simultaneously. Furthermore, the display on the display screen corresponding to each display level can be set for each worker.

The display modes on the display unit 30 shown in FIGS. 4 to 9 are merely examples, and other display modes may be used.

Although specific examples of the technology disclosed in this specification have been described above in detail, these are merely illustrative and do not limit the scope of the claims. The technology described in the claims includes various modifications and changes to the specific examples illustrated above. Further, the technical elements described in this specification or the drawings exhibit technical usefulness singly or in various combinations, and are not limited to the combinations described in the claims as filed.
