[0006] The display device disclosed in this specification displays the operating status of a production equipment having at least one production line for producing substrates. The display device includes a display unit, a display level selection unit, an acquisition unit, and a control unit. The display level selection unit can be operated by a user, and can input an instruction to select one of a plurality of pre-set display levels. The plurality of display levels at least include a display level that displays an error state that should cause the production line to stop operating. The acquisition unit can acquire a plurality of detection items representing the operating status of the production line. When an instruction to select one of the plurality of display levels is input from the display level selection unit, the control unit displays a display screen of one or more detection items among the plurality of detection items acquired by the acquisition unit and that have been pre-correlated with the selected display level on the display unit.

[0007] In the above-mentioned display device, a plurality of detection items representing the operating status of the production line are obtained. Then, when the user inputs an indication to select a certain display level, a display screen showing one or more detection items pre-established corresponding to the display level from among the obtained detection items is displayed on the display unit. That is, the operating status (detection item) that the user wants to display is classified into a plurality of display levels, and one or more detection items are respectively established corresponding to a plurality of display levels. Therefore, the user can limit the detection items corresponding to the selected display level only by selecting the display level, and the user can easily grasp the desired operating status. For example, when the input selects the indication of the display level for displaying an error state, the detection items corresponding to the error state are displayed.

[0017] In one embodiment of the present technology, the plurality of detection items may correspond to each of the detection items and to a partial image showing the detection item. Alternatively, the display screen may be composed of one or more partial images corresponding to the one or more detection items to be displayed.

[0018] In such a configuration, a display screen composed of a partial image showing a detection item to be displayed is displayed, thereby improving visibility.

[0019] In one embodiment of the present technology, the display device may further include a layout setting unit that can be operated by a user and can input an instruction for setting a layout of one or more of the partial images constituting the display screen. Alternatively, the control unit may display the display screen in which the partial images are arranged in the layout set by the layout setting unit on the display unit.

[0020] 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, by the user inputting an instruction to change the arrangement of a part of the images in the preset display screen layout, the display screen displayed on the display unit can be set to the layout desired by the user.

[0021] In one embodiment of the present technology, the display device may further include a display item setting unit, which can be operated by a user and can input an instruction to set one or more detection items corresponding to each display level. Alternatively, when an instruction to select a specific display level is input from the display level selection unit, the control unit displays a display screen of one or more detection items corresponding to the specific display level set by the display item setting unit on the display unit.

[0022] According to such a structure, the user can input instructions for setting detection items corresponding to a certain display level. For example, detection items that are pre-associated with a certain display level and are less important to the user can be deleted from the display screen, or detection items that are not pre-associated but are more important to the user can be re-associated with the display level. That is, the freedom of setting the detection items to be displayed on the display unit is high.

[0023] In one embodiment of the present technology, the production equipment may further include a plurality of production lines. The display device may further include a production line selection unit, which can be operated by a user and can input an instruction to select one of the plurality of production lines. For the plurality of production lines, the acquisition unit may respectively acquire a plurality of detection items indicating the operating status of the production line. The display level selection unit may select the display level for the production line selected by the production line selection unit. When the display level is selected by the display level selection unit, the control unit displays the display screen on the display unit for the production line selected by the production line selection unit.

[0024] According to such a structure, in a production facility having a plurality of production lines, a display level can be selected corresponding to the production line whose operating status is to be confirmed. Therefore, the operating status of the production line to be confirmed can be easily displayed, and only the display screen corresponding to the display level of the selected production line is displayed on the display unit, thereby improving visual recognition.

[0025] In one embodiment of the present technology, the display unit may be a touch panel capable of user input. Alternatively, the display level selection unit may display a plurality of icons corresponding to the plurality of display levels on the display unit, and the user may touch and select one of the plurality of icons displayed on the display unit to select the display level. Alternatively, the display screen may include icons of unselected display levels. Alternatively, when the user touches and selects the icon of the unselected display level in the display screen, the control unit may switch to a display screen corresponding to the touched and selected display level and display it on the display unit.

[0026] In the above configuration, the display screen displayed according to the selected display level includes a plurality of icons corresponding to the unselected display levels, so that the display screen can be easily switched to the display screen corresponding to the other display level simply by touching and selecting one of the plurality of icons.

[0027] In one embodiment of the present technology, a substrate production system may include any of the above display devices. Alternatively, the substrate production system may include: production equipment including at least one production line for producing substrates; and any of the above display devices provided in the production line.

[0028] (Example 1)

[0029] Hereinafter, the substrate production system 10 of the first embodiment will be described with reference to the accompanying drawings. Figure 1 As shown, 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 for displaying the operating status of the production facility 12. Although not shown, the display device 14 is connected to mounting machines 22 and 24 constituting each production line 20a to 20c. Each production line 20a to 20c is composed of a component mounting machine 22, a printing machine 24, etc., and produces circuit substrates 26a to 26c by mounting components on the transported substrate. In addition, the production facility 12 may not have a plurality of production lines, but may have only a single production line.

[0030] like Figure 2 As shown, the display device 14 includes a display unit 30, an operation unit 32, an acquisition unit 34, and a control unit 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, etc.), and a plurality of display levels are pre-set according to the operating status. In the present embodiment, the display level indicates one of an error level, a warning level, an information level, and a success level.

[0031] The error level indicates that the operation of the production lines 20a to 20c has stopped. For example, the production equipment 12 stops due to a communication error with a server (not shown) that controls the overall operation of the production lines 20a to 20c. The warning level indicates that the productivity of the production lines 20a to 20c has dropped significantly. For example, the overall equipment efficiency (OEE) has dropped significantly due to the occurrence of component mounting errors toward the circuit board by the component mounting unit (e.g., mounting head, suction nozzle, etc.) of the component mounting machine 22 with a predetermined frequency or more. The information level indicates that although the productivity of the production lines 20a to 20c will not be greatly affected, a slight defect has occurred. As a phenomenon, for example, the OEE has slightly dropped due to the occurrence of running out of components in the component supply unit (component feeder, etc.). The success level indicates that the production lines 20a to 20c are operating normally. Thus, in this embodiment, the operating conditions of the production lines 20a to 20c are classified into one of the four levels, and in the display process described later, information associated in advance with the classified display level is displayed on the display unit 30.

[0032] The operation unit 32 receives input of instructions from the user. The user can input various instructions to the display device 14 by operating the operation unit 32. The display unit 30 and the operation unit 32 function as a so-called touch panel. However, the operation unit 32 may be composed of a keyboard, a pointing device, etc., or may be provided separately from the display unit 30.

[0033] The acquisition unit 34 acquires a plurality of detection items indicating the operating conditions of the production lines 20a to 20c. As the detection items, for example, the operating conditions of the above-mentioned servers, the operating conditions of each production equipment 12, the operating conditions of the component mounting unit, the component supply unit, and the production conditions of the circuit board are listed. Each detection item is preliminarily associated with the above-mentioned display level according to the conditions at the time of acquisition. For example, when the condition of the production equipment 12 being stopped is acquired as the detection item, the detection item is associated with the error level when a communication error of the server occurs. In addition, for example, when the operating conditions of the component mounting unit are acquired as the detection item, when a component installation error occurs at a predetermined frequency or more, the detection item is associated with the warning level, and when the component installation error is less than the predetermined frequency, the detection item is associated with the success level. In addition, for example, when the operating conditions of the component supply unit are acquired as the detection item, when a component is exhausted, the detection item is associated with the information level, and when the component is normally installed, the detection item is associated with the success level. In this way, in the display device 14 , the detection item is associated with a certain display level in advance according to the state of the detection item acquired by the acquisition unit 34 .

[0034] The control unit 36 ​​is constituted 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.

[0035] Next, refer to Figure 3 , the processing of the display device 14 displaying the operating status of each production line 20a~20c on the display unit 30 is described. When the operation of the production equipment 12 starts (that is, when the production of the circuit board starts), the production lines 20a~20c are each individually executed. Figure 3 Because Figure 3 The processing of is performed in the same manner for each of the production lines 20a to 20c, so the following description is performed on the production line 20a. Figure 3 of the processing situation.

[0036] When the operation of the production equipment 12 starts, in S10, the control unit 36 ​​obtains the operation status of the production line 20a. Specifically, as described above, the operation status of the server that controls all operations of the production line 20a, the operation status of each production equipment 12, the operation status of each component mounting machine 22 (i.e., the operation status of the component mounting unit and the component supply unit), and the production status of the circuit board are obtained.

[0037] After S12, the control unit 36 ​​determines which display level the acquired detection items are associated with. In S12, the control unit 36 ​​determines whether there is a detection item associated with an error level among the acquired detection items. For example, if the detection items include a detection item indicating that a communication error has occurred with the server, the control unit 36 ​​determines that the detection item is associated with an error level and proceeds to S14. Then, as shown in FIG. Figure 4 As shown, in S14, the control unit 36 ​​displays the icon I1 corresponding to the error level together with the image B1 representing the production line 20a on the display unit 30. On the other hand, if the detection item associated with the error level is not included, the process proceeds to S16.

[0038] In S16, the control unit 36 ​​determines whether there is a detection item corresponding to the warning level among the acquired detection items. For example, if the detection items include a detection item indicating that the component mounting unit has a mounting error with a predetermined frequency or more, the control unit 36 ​​determines that the detection item corresponds to the warning level and enters 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 there is no detection item corresponding to the warning level, the process proceeds to S20.

[0039] In S20, the control unit 36 ​​determines whether there is a detection item corresponding to the information level among the acquired detection items. For example, when the detection items include a detection item indicating that the component supply unit has run out of components, the control unit 36 ​​determines that the item corresponds to the information level and enters S22. Then, in S22, the control unit 36 ​​displays an icon corresponding to the information level on the display unit 30. On the other hand, when there is no detection item corresponding to the information level, the control unit 36 ​​displays an icon corresponding to the success level on the display unit 30 in S24.

[0040] In S26, the control unit 36 ​​determines whether an instruction to select a display level is input. Figure 4 If the icon I1 corresponding to the error level shown is displayed, the process proceeds to S28. If no instruction to select the display level is input, the control unit 36 ​​returns to S10. That is, the control unit 36 ​​repeatedly performs the process of obtaining the operating status of the production line 20a (S10) and determining the display level to be displayed (S12 to S24) until receiving the input based on the user's instruction. In addition, the process of S26 is an example of the process performed by the "display level selection unit".

[0041] When the control unit 36 ​​receives the input of the instruction to select the display level, in S28, the control unit 36 ​​displays the display screen on the display unit 30. Specifically, when the control unit 36 ​​receives the input of the selection icon I1, as shown in FIG. Figure 5 As shown, a display screen S1 showing the detection items corresponding to the error levels is displayed on the display unit 30. In the display screen S1, the operation status of the server (the status in which a communication error has occurred) as the detection item corresponding to the error level is displayed as a partial image P1 showing the detection item. In addition, in the case where there are detection items corresponding to the error level in addition to the communication error of the server, for each of the detection items, partial images P2 and P3 corresponding to the detection item are displayed. That is, the control unit 36 ​​displays the display screen S1 composed of a 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 Figure 5 As shown, the partial images P1 to P3 include graphs and tables showing the operation status. In this way, the operation status of the production line 20a is displayed on the display unit 30. After executing S28, the control unit 36 ​​ends a series of processing.

[0042] In addition, as mentioned above, Figure 3 The display processing is performed separately for each of the production lines 20a to 20c. Figure 4 As shown, for production lines 20b and 20c, icons I2 and I3 corresponding to the display levels of the statuses corresponding to the acquired detection items and images B2 and B3 representing production lines 20b and 20c are displayed on the display unit 30. By touching icons Ib and Ic, the user can display a display screen representing the operating status of production lines 20b and 20c in the same manner as the display screen S1 of production line 20a.

[0043] As described above, in the present embodiment, when the production equipment 12 starts to operate, the control unit 36 ​​enables the acquisition unit 34 to acquire a plurality of detection items representing the operating conditions of the production lines 20a to 20c. Then, the control unit 36 ​​determines that the plurality of detection items each establishes a corresponding display level, and enables 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 representing the detection items corresponding to the display level is displayed. In this way, in the present embodiment, detection items pre-classified according to the selected display level are displayed. That is, the user can confirm the detection items (operating conditions) corresponding to the display level by simply inputting an instruction to select the displayed display level from a plurality of pre-set display levels.

[0044] (Example 2)

[0045] In the above-mentioned first embodiment, when an icon corresponding to a certain display level is selected, a display screen showing the detection items preliminarily corresponding to the display level is displayed on the display unit 30. In contrast, in the second embodiment, it is configured so that the user can set the detection items corresponding to the display level for each display level. That is, the user can set the detection items corresponding to a certain display level by operating the operation unit 32. This setting is similar to the above-mentioned first embodiment. Figure 3 The display processing shown is implemented separately.

[0046] For example, in embodiment 1, the detection item indicating that there is an installation error based on the component installation unit with a predetermined frequency or more is established in correspondence with the warning level, but according to different users, there is a situation where the importance of the detection item is relatively low. In the present embodiment, in such a case, the user can exclude the detection item indicating that there is an installation error with a predetermined frequency or more from the warning level. In this case, the user can also input the instruction to establish a corresponding relationship between the detection item and the information level or the success level. By setting it in this way, even if there is an installation error with a predetermined frequency or more, the icon corresponding to the warning level will not be displayed in the display unit 30, but the icon corresponding to the information level or the success level will be displayed. In addition, for example, in embodiment 1, the detection item indicating that there is a component exhaustion in the component supply unit is established in correspondence with the information level, but according to different users, there is a situation where the importance of the detection item is relatively high. In the present embodiment, in such a case, the user can input the indication that the display level corresponding to the detection item indicating that there is a component exhaustion is changed from the information level to the error level, for example. By setting it in this way, in the case of component exhaustion, the icon corresponding to the error level is displayed in the display unit 30. Thus, in this embodiment, the preset correspondence relationship between the display level and the detection item can be changed. In other words, the user can freely set the detection item to be displayed when a certain display level is selected.

[0047] In the first embodiment, the display screen corresponding to a certain display level is composed of a plurality of pre-set partial images. In contrast, in the present embodiment, the layout of the partial images constituting the display screen displayed on the display unit 30 (the number, type, arrangement, size, etc. of the partial images) can be set by the user. That is, the user can set the layout of the partial images constituting the display screen by operating the operation unit 32. This setting is similar to Figure 3 The display processing shown is implemented separately.

[0048] For example, in the case where the inspection item is the production status of a circuit substrate, there may be multiple partial images as partial images showing the inspection item, such as the production speed of the circuit substrate, the progress ratio of the production plan, the yield rate of the produced circuit substrate, etc. Therefore, in the case where the production status of the circuit substrate is obtained as an inspection item, the inspection item can be associated with multiple partial images. In this embodiment, in such a case, the user can set the layout of the partial images showing the production status of the circuit substrate (i.e., the layout of the display screen). For example, Figure 6 As shown, the user can select and freely arrange the partial images to be displayed on the display screen S2 showing the production status of the circuit board from the candidate group G including the plurality of partial images P4 to P8. Figure 6 As an example, the configuration method of the partial image P4 (such as dragging and dropping) is shown. Thus, in this embodiment, a desired partial image can be selected from a plurality of partial images P4 to P8 showing the production status of the circuit substrate, and the layout of the display screen S2 can be freely set.

[0049] (Variation Example)

[0050] Furthermore, in the above-mentioned embodiments, when the number of production lines of the production equipment 12 is relatively large, a screen for inputting an operation of selecting a production line whose operating status is to be displayed may be displayed. Figure 3 After S10, Figure 7 As shown in FIG. 1 , selection images Ca to Ch for selecting production lines 20a to 20h are displayed together with images Ba to Bh representing production lines 20a to 20h, respectively, so that an operation of selecting a production line can be input. Then, for example, when the control unit 36 ​​receives an input of an operation of selecting production line 20a (based on a user's touch of the selection image Ca), only the selection image Ca can be input. Figure 4 The image B1 shown is displayed on the display unit 30. In such a configuration, when there are a plurality of production lines, each production line can be displayed at a glance, so that visibility is improved.

[0051] In addition, in the above-mentioned embodiment Figure 4 In the example, only one icon corresponding to one display level is displayed for each of the production lines 20a to 20c. However, icons corresponding to all display levels may be displayed, or icons corresponding to a portion of the display levels may be displayed. For example, in the production line 20a, when detection items corresponding to the warning level, information level, and success level are obtained, as shown in FIG. Figure 8 As shown, the icon I2 corresponding to the warning level may be displayed, and icons I3 and I4 corresponding to information levels and success levels with lower urgency may be displayed on the display unit 30 together.

[0052] In addition, in the above embodiment, if Fig. 9 As shown, it is also possible to display icons corresponding to unselected display levels (in Fig. 9 In the example, icons I2, I3, and I4 corresponding to each display level other than the error level are displayed. In such a structure, it is possible to easily shift to a display screen corresponding to other display levels.

[0053] The display device 14 is not limited to a single device, but may be composed of a plurality of devices. For example, a plurality of separate devices may function as the display unit 30 , the operation unit 32 , the acquisition unit 34 , and the control unit 36 ​​.

[0054] In addition, a plurality of display units 30 may be provided. For example, the display device 14 may also have a plurality of display units 30 assigned to each operator. In such a structure, each display screen corresponding to a different display level can be confirmed at the same time. In addition, the display of the display screen corresponding to each display level can be set for each operator.

[0055] Figures 4 to 9 The display method of the direction display unit 30 shown is just an example, and other display methods may be used.

The technology described in the claims includes technologies obtained by various deformations and changes to the specific examples of the above examples. In addition, the technical elements described in this specification or the drawings exert their technical usefulness alone or in various combinations, and are not limited to the combinations recorded in the claims at the time of application.
