[0023] 1. Implementation Method

[0024] 1-1. Example of the structure of substrate production equipment PF0

[0025] The substrate production equipment PF0 uses a substrate operation machine WM0 that performs a predetermined substrate operation on the substrate 90 to produce the substrate product 900. The type and number of the substrate operation machine WM0 are not limited. Figure 1 As shown, the substrate production equipment PF0 of the present embodiment includes a plurality of (five) substrate working machines WM0 including a printer WM1, a print inspection machine WM2, a component mounting machine WM3, a visual inspection machine WM4, and a reflow furnace WM5.

[0026] In the substrate production facility PF0, the substrate 90 is sequentially conveyed in a plurality of substrate alignment machines WM0 and the substrate alignment operations are sequentially performed to produce a substrate product 900. Specifically, the substrate 90 is Figure 1 The upstream printer WM1 is carried in. The substrate transport device sequentially transports the substrate 90 in the plurality of substrate handling machines WM0, and the substrate handling machines WM0 sequentially perform predetermined substrate handling operations. Then, the substrate 90 is carried out from the downstream reflow furnace WM5.

[0027] The printer WM1 prints solder on the mounting positions of the plurality of components 91 on the substrate 90. The print inspection machine WM2 inspects the printing state of the solder printed by the printer WM1. The component assembly machine WM3 assembles the plurality of components 91 on the substrate 90 printed with solder. The component assembly machine WM3 may be one or more. In the case where a plurality of component assembly machines WM3 are provided, the plurality of component assembly machines WM3 can assemble the plurality of components 91 in a shared manner.

[0028] The component assembly machine WM3 of the present embodiment includes a plurality of (eight) first component assembly machines WM31 and a plurality of (two) second component assembly machines WM32. The first component assembly machine WM31 is located at a position on the upstream side of the appearance inspection machine WM4, and performs the first stage of assembly processing. The second component assembly machine WM32 is located at a position on the downstream side of the appearance inspection machine WM4, and performs the second stage of assembly processing. For example, the first component assembly machine WM31 assembles small components, and the second component assembly machine WM32 straddles the assembled small components and assembles large components that are higher than the small components. In addition, it is also possible that the first component assembly machine WM31 assembles the shielding object component, and the second component assembly machine WM32 assembles the shielding component in a manner that covers the assembled shielding object component. In this way, the component assembly machine WM3 of the present embodiment can also assemble multiple components 91 at the same assembly position on the substrate 90.

[0029] The appearance inspection machine WM4 inspects the assembly state of the plurality of components 91 assembled by the component assembly machine WM3. The appearance inspection machine WM4 of this embodiment inspects the assembly state of the components 91 assembled by the first component assembly machine WM31. The appearance inspection machine WM4 may also be provided on the downstream side of the second component assembly machine WM32, but in this embodiment, the assembly state of the components 91 assembled by the second component assembly machine WM32 is inspected by the second component assembly machine WM32. In addition, the appearance inspection machine WM4 may also be provided on the downstream side of the reflow oven WM5.

[0030] The reflow oven WM5 heats the substrate 90 on which a plurality of components 91 are mounted by the component mounting machine WM3, melts the solder, and performs soldering. In this way, the substrate production equipment PF0 can use a plurality of substrate handling machines WM0 to sequentially carry the substrate 90, perform production processes including inspection processes, and thereby produce substrate products 900. In addition, the substrate production equipment PF0 can also be equipped with, for example, a function inspection machine, a buffer device, a substrate supply device, a substrate turning device, an adhesive coating device, an ultraviolet irradiation device, and other substrate handling machines WM0 as needed.

[0031] The plurality of substrate work machines WM0 and the management device WC0 constituting the substrate production equipment PF0 are connected to be able to communicate via a wired or wireless communication unit LC0. In addition, various methods can be used as the communication method. In the present embodiment, a local area information communication network (LAN: Local Area Network) is formed by the plurality of substrate work machines WM0 and the management device WC0. Thus, the plurality of substrate work machines WM0 can communicate with each other via the communication unit LC0. In addition, the plurality of substrate work machines WM0 can communicate with the management device WC0 via the communication unit LC0.

[0032] The management device WC0 controls the plurality of substrate work machines WM0 constituting the substrate production equipment PF0 and monitors the operation status of the substrate production equipment PF0. Various control data for controlling the plurality of substrate work machines WM0 are stored in the management device WC0. The management device WC0 sends control data to each of the plurality of substrate work machines WM0. In addition, each of the plurality of substrate work machines WM0 sends the operation status and production status to the management device WC0.

[0033] The management device WC0 can be provided with a data server 80. The data server 80 can, for example, store the acquired data acquired by the substrate work machine WM0 during the substrate work. The acquired data includes various image data captured by the substrate work machine WA0. The acquired data includes the record (log data) of the operating status acquired by the substrate work machine WM0.

[0034] 1-2. Configuration example of component mounting machine WM3

[0035] The component mounting machine WM3 mounts a plurality of components 91 on the substrate 90. Figure 2 As shown, the component mounting machine WM3 includes a substrate conveying device 11, a component supply device 12, a component transfer device 13, a component camera 14, a substrate camera 15, and a control device 16. In this specification, the conveying direction of the substrate 90 is represented by the X-axis direction. The direction orthogonal to the X-axis direction in the horizontal plane is represented by the Y-axis direction. The direction orthogonal to the X-axis direction and the Y-axis direction is represented by the Z-axis direction.

[0036] The substrate transport device 11 is composed of, for example, a belt conveyor, etc., and transports the substrate 90 along the transport direction (X-axis direction). The substrate transport device 11 transports the substrate 90 into the component mounting machine WM3 and positions the substrate 90 at a predetermined position in the machine. After the assembly process of the plurality of components 91 by the component mounting machine WM3 is completed, the substrate transport device 11 transports the substrate 90 out of the component mounting machine WM3.

[0037] The component supply device 12 supplies a plurality of components 91 to be mounted on the substrate 90. The component supply device 12 has a plurality of feeders 121 arranged along the conveying direction (X-axis direction) of the substrate 90. The plurality of feeders 121 respectively convey the carrier tape containing the plurality of components 91 at intervals, and supply the components 91 in a manner that can be picked up at the supply position located at the front end side of the feeder 121. In addition, the component supply device 12 can also supply electronic components (for example, lead components, etc.) that are relatively large compared to chip components, etc., in a state arranged on a tray.

[0038] The component transfer device 13 includes a head drive device 131 and a moving table 132. The head drive device 131 is configured to move the moving table 132 in the X-axis direction and the Y-axis direction through a direct-acting mechanism. On the moving table 132, an assembly head 20 is provided in a manner that can be loaded and unloaded (replaced) by a clamping component. The assembly head 20 uses at least one holding component 21 to pick up and hold the component 91 supplied by the component supply device 12, and assembles the component 91 on the substrate 90 positioned by the substrate conveying device 11. The holding component 21 can use, for example, a suction nozzle, a chuck, etc.

[0039] The component camera 14 and the substrate camera 15 can use a known imaging device. The component camera 14 is fixed to the base of the component assembly machine WM3 in such a manner that the optical axis becomes the upward direction (vertically upward direction) of the Z-axis direction. The component camera 14 can photograph the component 91 held by the holding member 21 from below. The substrate camera 15 is provided on the movable table 132 of the component transfer device 13 in such a manner that the optical axis becomes the downward direction (vertically downward direction) of the Z-axis direction. The substrate camera 15 can photograph the substrate 90 from above. The component camera 14 and the substrate camera 15 perform imaging based on a control signal sent from the control device 16. The image data captured by the component camera 14 and the substrate camera 15 are sent to the control device 16.

[0040] The control device 16 includes a known computing device and a storage device, and constitutes a control circuit. Information output from various sensors provided in the component mounting machine WM3, image data, etc. are input to the control device 16. The control device 16 sends a control signal to each device based on a control program and pre-set predetermined mounting conditions, etc.

[0041] For example, the control device 16 causes the substrate camera 15 to photograph the substrate 90 positioned by the substrate transport device 11. The control device 16 performs image processing on the image photographed by the substrate camera 15 to recognize the positioning state of the substrate 90. In addition, the control device 16 causes the holding member 21 to pick up and hold the component 91 supplied by the component supply device 12, and causes the component camera 14 to photograph the component 91 held by the holding member 21. The control device 16 performs image processing on the image photographed by the component camera 14 to recognize whether the component 91 is appropriate or not and the holding posture of the component 91.

[0042] The control device 16 moves the holding member 21 toward the upper side of the scheduled assembly position that is preset by the control program, etc. In addition, the control device 16 corrects the scheduled assembly position based on the positioning state of the substrate 90, the holding posture of the component 91, etc., and sets the assembly position of the actual assembly component 91. The scheduled assembly position and the assembly position include the rotation angle in addition to the position (X coordinate and Y coordinate).

[0043] The control device 16 corrects the target position (X coordinate and Y coordinate) and the rotation angle of the holding member 21 in accordance with the assembly position. The control device 16 lowers the holding member 21 at the corrected rotation angle at the corrected target position to assemble the component 91 on the substrate 90. The control device 16 performs the assembly process of assembling a plurality of components 91 on the substrate 90 by repeatedly performing the above-mentioned pick-and-place cycle.

[0044] 1-3. Configuration Example of Operation Status Display Device 40

[0045] The operating status display device 40 displays the operating status of the substrate production equipment PF0. The operating status display device 40 can be provided in various electronic computers, control devices, etc. Figure 1 As shown, the operation status display device 40 of this embodiment is provided in an electronic computer 70. The electronic computer 70 has a known computing device, a storage device, an input device, and an output device (including a display device DP0). The operation status display device 40 can also be formed, for example, on a substrate operation machine WM0, a management device WC0, a host computer that manages multiple substrate production equipment PF0, or on the cloud.

[0046] In addition, if the operating status display device 40 is understood as a control block, it includes an acquisition unit 41 and a display unit 42. The operating status display device 40 may also include a determination unit 43. Figure 1 As shown in FIG. 1 , the operating status display device 40 of the present embodiment includes an acquisition unit 41, a display unit 42, and a determination unit 43. Figure 3The control is performed according to the flowchart shown in FIG. 4 . The acquisition unit 41 performs the process shown in step S11. The display unit 42 performs the process shown in step S13. The determination unit 43 performs the process shown in step S12.

[0047] 1-3-1. Acquisition Unit 41

[0048] The acquisition unit 41 acquires the implementation time period TP0 (in which the production change adjustment operation required when the type of the produced substrate product 900 is switched) for each substrate operation machine WM0 based on the production information acquired by the substrate production equipment PF0 during the production of the substrate product 900. Figure 3 Step S11 shown).

[0049] The information related to the operation status acquired by the substrate work machine WM0 during the production of the substrate product 900 is included in the production information. The acquisition unit 41 can acquire the implementation time period TP0 based on the record (log data) of the operation status acquired by the substrate work machine WM0, for example. As described above, the log data is stored in Figure 1 The acquisition unit 41 of the present embodiment acquires log data from the data server 80 and acquires the implementation time period TP0. For example, the time when the substrate 90 is carried in and out of the substrate operation machine WM0 is information related to the operation status of the substrate operation machine WM0, which is included in the production information and recorded in the log data.

[0050] Here, the production before the type of substrate product 900 is switched is referred to as the first production, and the production after the type of substrate product 900 is switched is referred to as the second production. When the substrate operation machine WM0 unloads the last substrate 90 of the substrate product 900 produced in the first production, the substrate operation machine WM0 can start the production change adjustment operation for the second production. In addition, when the first predetermined number of substrates 90 of the substrate product 900 produced in the second production are moved in or out of the substrate operation machine WM0, it can be said that the substrate operation machine WM0 has completed the production change adjustment operation for the second production.

[0051] To this end, the acquisition unit 41 acquires the following time period as the implementation time period TP0: from the moment when the last substrate 90 of the substrate product 900 produced in the first production is moved out to the moment when the initial predetermined number of substrates 90 of the substrate product 900 produced in the second production is moved in or out. The above-mentioned predetermined number can be one sheet or multiple sheets. For example, there is a situation where the producer of the substrate product 900 conducts a trial production of the substrate product 900 during the production change adjustment operation. In this case, the above-mentioned predetermined number is set to match the number of sheets of the substrate 90 that have been trial-produced. In the case where the trial production of the substrate product 900 is not performed in the production change adjustment operation, the above-mentioned predetermined number is set to one sheet.

[0052] In addition, there is a case where the producer of the substrate product 900 considers that the production change adjustment work for the second production is completed when the first predetermined number of substrates 90 of the substrate product 900 produced in the second production is carried in. In this case, the acquisition unit 41 acquires the following time period as the implementation time period TP0: from the time when the last substrate 90 of the substrate product 900 produced in the first production is carried out to the time when the first predetermined number of substrates 90 of the substrate product 900 produced in the second production is carried in.

[0053] On the other hand, there is a case where the producer of the substrate product 900 considers that the production change adjustment work for the second production is completed when the first predetermined number of substrates 90 of the substrate product 900 produced in the second production are unloaded. In this case, the acquisition unit 41 acquires the following time period as the implementation time period TP0: from the time when the last substrate 90 of the substrate product 900 produced in the first production is unloaded to the time when the first predetermined number of substrates 90 of the substrate product 900 produced in the second production is unloaded.

[0054] In addition, the existence of trial production of substrate product 900 and the definition of the end of the production change adjustment operation are information related to the operating status of the substrate operation machine WM0, included in the production information, and recorded in the log data. In addition, information related to the first production and the second production (including the switching timing) is information related to the operating status of the substrate operation machine WM0, included in the production information, and recorded in the log data.

[0055] 1-3-2. Display unit 42

[0056] The display unit 42 displays in a time series a graph of at least one of the implementation time period TP0 of each substrate work machine WM0 of the plurality of substrate work machines WM0 and the implementation time period TP0 of the predetermined substrate work machine WM0 of the substrate production equipment PF0 ( Figure 3 Step S13 shown).

[0057] The display unit 42 can be displayed with respect to, for example, Figure 1 The display device DP0 shown in the figure displays the graph. The display device DP0 can use a well-known display device such as a liquid crystal display device, for example. The display device DP0 displays the above-mentioned implementation time period TP0 in a graph in a time sequence. In addition, the display format of the graph display is not limited, and the display unit 42 can display the implementation time period TP0 in a graph in various display formats.

[0058] Figure 4 An example of a graph display based on the display unit 42 is shown. In this figure, the implementation time period TP0 of each component assembly machine WM3 of the plurality of (ten) component assembly machines WM3 is graphed in time sequence. Specifically, in this figure, the implementation time period TP0 of each first component assembly machine WM31 of the plurality of (eight) first component assembly machines WM31 is graphed in time sequence, and the implementation time period TP0 of each second component assembly machine WM32 of the plurality of (two) second component assembly machines WM32 is graphed in time sequence.

[0059] In addition, in this figure, for the convenience of illustration, from the first component mounting machine WM31a on the most upstream side to the first component mounting machine WM31h on the most downstream side, reference numbers are given in the order of conveying the substrate 90. Similarly, in this figure, for the convenience of illustration, from the second component mounting machine WM32a on the most upstream side to the second component mounting machine WM32b on the most downstream side, reference numbers are given in the order of conveying the substrate 90.

[0060] In addition, in this figure, the implementation time period TP0 of the predetermined substrate operation machine WM0 (for example, the first component assembly machine WM31h and the second component assembly machine WM32b) for the substrate production equipment PF0 is graphically displayed in time sequence. The first component assembly machine WM31h is the last (most downstream) first component assembly machine WM31 among the multiple (eight) first component assembly machines WM31, and the second component assembly machine WM32b is the last (most downstream) second component assembly machine WM32 among the multiple (two) second component assembly machines WM32.

[0061] Furthermore, in the figure, the implementation time period TP0 of the predetermined substrate operation machine WM0 (for example, the second component assembly machine WM32b) of the substrate production equipment PF0 is graphically displayed in chronological order. The second component assembly machine WM32b is the last (most downstream) component assembly machine WM3 among the plurality of (ten) component assembly machines WM3. In addition, the display unit 42 can display any first component assembly machine WM31 and second component assembly machine WM32. In addition, the horizontal axis of the figure represents the time, and the vertical axis represents the symbol number of the above-mentioned substrate operation machine WM0 (component assembly machine WM3).

[0062] The time T11 to time T24 on the horizontal axis of the figure represent the time in units of a certain time starting from the reference time (time 0). The above-mentioned certain time can be arbitrarily set within the range in which the tendency of the implementation time period TP0 can be grasped. The above-mentioned certain time can be set, for example, based on the required time required for the loading and unloading operation of one article 30. For example, when the above-mentioned required time is 1 minute, the above-mentioned certain time can be set, for example, to several minutes (for example, about 2 minutes to 5 minutes).

[0063] In addition, the symbol numbers of the substrate operation machine WM0 (component mounting machine WM3) on the vertical axis of the figure are listed in the order described above from the substrate operation machine WM0 (component mounting machine WM3) on the upstream side to the substrate operation machine WM0 (component mounting machine WM3) on the downstream side. Furthermore, the time 0 and the time T31 to the time T49 shown at both ends of the arrow of the implementation time period TP0 indicate the start time or the end time of the production change adjustment operation.

[0064] The substrate 90 is sequentially transported from the component assembly machine WM3 on the most upstream side, that is, the first component assembly machine WM31a, to the component assembly machine WM3 on the most downstream side, that is, the second component assembly machine WM32b, so that the first production is completed earliest in the first component assembly machine WM31a, and the production change adjustment operation is started earliest. Then, the production change adjustment operation is completed earliest in the first component assembly machine WM31a, and the second production is started earliest.

[0065] The component assembly machine WM3 on the downstream side of the first component assembly machine WM31a sequentially finishes the first production, starts the production change adjustment operation, finishes the production change adjustment operation, and starts the second production. As a result, the first production ends the latest and the production change adjustment operation starts the latest in the second component assembly machine WM32b. Then, the production change adjustment operation ends the latest in the second component assembly machine WM32b and the second production starts the earliest.

[0066] like Figure 4As shown in the graph display of the implementation time period TP0 of each of the plurality of (ten) component assembly machines WM3, the time required for the production change adjustment operation shown in the implementation time period TP0 increases at a substantially constant ratio from the first component assembly machine WM31a on the most upstream side to the second component assembly machine WM32b on the most downstream side. In this case, the user of the operation status display device 40 can visually confirm that the production change adjustment operation has been successfully performed.

[0067] Figure 5 Another example of a graph display by the display unit 42 is shown. Figure 4 However, in Figure 5 In the example, the time T39 shown at the front end of the arrow indicating the implementation time period TP0 is represented by the time T39a, and the time T41 is represented by the time T41a. Similarly, the time T43 is represented by the time T43a, and the time T45 is represented by the time T45a. The time T47 is represented by the time T47a, and the time T49 is represented by the time T49a.

[0068] like Figure 5 As shown in the graph of the implementation time period TP0 of each component mounting machine WM3 of the plurality of (ten) component mounting machines WM3, the time T39a is Figure 4 That is, the time required for the production change adjustment operation in the first component mounting machine WM31e is later than the time T39 shown. Figure 4 The above contents about the first component mounting machine WM31e are also the same for the component mounting machine WM3 on the downstream side of the first component mounting machine WM31e.

[0069] In addition, the increase ratio of the time required for the production change adjustment operation of the second component mounting machine WM32a relative to the first component mounting machine WM31h increases sharply compared with the component mounting machine WM3 from the first component mounting machine WM31e to the first component mounting machine WM31h. In this case, the user of the operation status display device 40 can visually confirm that there is a problem in the production change adjustment operation in the first component mounting machine WM31e and the second component mounting machine WM32a.

[0070] The display unit 42 can display specific information together with the implementation time period TP0. The specific information is information related to at least one of the production program switching timing TM1, the loading and unloading timing TM2 of the article 30 loaded and unloaded to the substrate operation machine WM0, the verification timing TM3 of the article 30, the first time period TZ1, the second time period TZ2, and the trial production time period TZ3, and is included in the production information.

[0071] The production program is a production program for driving and controlling the substrate operation machine WM0, and is specified by the production plan of the substrate product 900. The production program switching timing TM1 refers to the timing of switching from the production program used in the first production to the production program used in the second production. The switching of the production program can be performed by the management device WC0 that manages the substrate operation machine WM0, and can also be performed by the operator.

[0072] The article 30 is not limited to any article that is loaded and unloaded from the substrate operation machine WM0 during the production changeover operation. For example, when the substrate operation machine WM0 is a component mounting machine WM3, Figure 2 The feeder 121, the mounting head 20, and the holding member 21 shown are included in the article 30. In addition, the tape reel on which the carrier tape accommodating the component 91 is wound and the component tray accommodating the component 91 are included in the article 30. Furthermore, for example, when the substrate operation machine WM0 is a printer WM1, the mask, the squeegee, and the dispensing head are included in the article 30.

[0073] The loading and unloading operation of the article 30 can be performed by an operator or a replacement device for replacing the article 30. For example, it is assumed that an operator replaces Figure 2 In this case, when installing the feeder 121 in the slot, the operator uses a reader to read the identification code attached to the feeder 121 and installs the feeder 121 in the predetermined slot of the component supply device 12.

[0074] When the feeder 121 is equipped in the slot, power is supplied to it from the component mounting machine WM3 via the connector, and it becomes a state in which communication with the component mounting machine WM3 is possible. Thus, the slot of the component supply device 12 and the identification information of the feeder 121 equipped in the slot are associated, and installation information indicating that the feeder 121 is equipped is recorded. On the contrary, when the feeder 121 is removed from the slot, the component mounting machine WM3 cannot communicate with the feeder 121. Thus, removal information indicating that the feeder 121 is removed is recorded.

[0075] The acquisition unit 41 acquires the time when the feeder 121 was removed, which is included in the removal information of the feeder 121 removed by the loading and unloading operation, as the removal timing TM21 of the feeder 121. Similarly, the acquisition unit 41 acquires the time when the feeder 121 was equipped, which is included in the installation information of the feeder 121 equipped by the loading and unloading operation, as the installation timing TM22 of the feeder 121.

[0076] Thus, the loading and unloading timing TM2 of the feeder 121 includes the removal timing TM21 and the installation timing TM22. The above contents about the feeder 121 are also the same for the other articles 30 described above. In addition, the loading and unloading timing TM2 of the article 30 can also be known using the detection signal of the detector that detects the loading and unloading of the article 30, for example.

[0077] Furthermore, in a substrate operation machine WM0, when a plurality of articles 30 are loaded and unloaded, the loading and unloading timing TM2 may include at least the disassembly timing TM21 of the article 30 that is first loaded and unloaded and the installation timing TM22 of the article 30 that is last loaded and unloaded. In this case, when at least one of the required time and the operation interval of the loading and unloading operation includes a loading and unloading operation that is greater than a predetermined threshold, the loading and unloading timing TM2 may further include the disassembly timing TM21 of the article 30 that is being loaded and unloaded and the installation timing TM22 of the article 30 that is being loaded and unloaded. In addition, in the loading and unloading operation, a plurality of articles 30 may be loaded and unloaded at the same time.

[0078] The item 30 verification timing TM3 is a timing for judging whether the item 30 equipped in the substrate work machine WM0 is correct. The item 30 to be equipped in the substrate work machine WM0 is specified in the production plan of the substrate product 900. When the item 30 equipped in the substrate work machine WM0 is the item 30 specified in the production plan of the substrate product 900, the substrate work machine WM0 judges that the correct item 30 is equipped.

[0079] On the contrary, when the article 30 equipped in the substrate work machine WM0 is different from the article 30 specified in the production plan of the substrate product 900, the substrate work machine WM0 determines that an incorrect article 30 is equipped. The acquisition unit 41 acquires the time when the correct article 30 is determined to be equipped for all the articles 30 loaded and unloaded by the loading and unloading operation as the verification timing TM3 of the article 30. In addition, the acquisition unit 41 can also acquire the time when the incorrect article 30 is determined to be equipped as the verification timing TM3 of the article 30.

[0080] The first time period TZ1 is a time period from the completion of the verification of the article 30 to the time when the substrate 90 is carried into the substrate operation machine WM0. The acquisition unit 41 acquires the time period from the time when the correct article 30 is determined to be equipped to the time when the substrate 90 is carried into the substrate operation machine WM0 as the first time period TZ1 for all articles 30 loaded and unloaded by the loading and unloading operation. In addition, the second time period TZ2 is a time period from when the substrate operation machine WM0 stops due to a defect in the production change adjustment operation to when it can be operated again.

[0081] For example, there is a case where the substrate work machine WM0 stops due to an abnormality of the article 30 equipped to the substrate work machine WM0 by the loading and unloading operation, an abnormality of the equipment constituting the substrate work machine WM0 after the loading and unloading operation, etc. In this case, the operator removes the main cause of the stop of the substrate work machine WM0 and restores the substrate work machine WM0. The acquisition unit 41 acquires the time period from the time when the substrate work machine WM0 stops to the time when the substrate work machine WM0 is restored and can operate as the second time period TZ2.

[0082] The trial production time period TZ3 is a time period during which trial production of the substrate product 900 is performed in the production changeover adjustment operation. The acquisition unit 41 acquires a time period from the start time of the trial production of the substrate product 900 to the end time of the trial production of the substrate product 900 as the trial production time period TZ3.

[0083] The display unit 42 can be, for example, Figure 4 or Figure 5 In the graph display shown, the specific information is displayed together with the implementation time period TP0. In this case, the display unit 42 can, for example, change the display color according to each type of specific information, and display the implementation time period TP0 and the specific information in a recognizable manner. In addition, the more the number of substrate work machines WM0 displayed, the lower the visual confirmation of the user of the operation status display device 40. Similarly, the more types of specific information displayed, the lower the visual confirmation of the user of the operation status display device 40.

[0084] To this end, the display unit 42 may display the scheduled implementation time period TP0 selected by the user and specific information about the implementation time period TP0 in a pop-up window. Figure 6 Show Figure 4 An example of a pop-up window displaying a chart. Figure 7 express Figure 5 An example of a pop-up window showing a chart. Figure 8 express Figure 5 Another example of a pop-up window displaying a chart. Figure 6 As shown, the display unit 42 can, for example, Figure 4 The front surface of the diagram shown shows the predetermined implementation time period TP0 and specific information about the implementation time period TP0. Figure 7 as well as Figure 8 In the pop-up window shown, the back side is omitted. Figure 5 The diagram shown is displayed.

[0085] For example, the electronic computer 70 is equipped with a mouse (input device). When the user moves the mouse, the mouse pointer moves on the screen (on the graph display) along with the movement of the mouse. Figure 4 When the mouse pointer is moved to the first component mounting machine WM31a in the diagram display shown, the display unit 42 executes Figure 6 The pop-up window display in the upper stage is shown. In the pop-up window display in the upper stage, the production program switching timing TM1, the loading and unloading timing TM2 of the item 30, the verification timing TM3 of the item 30, and the trial production time zone TZ3 are displayed for the first component mounting machine WM31a.

[0086] In addition, the loading and unloading timing TM2 of the item 30 includes the disassembly timing TM21 and the installation timing TM22. In addition, the symbol number surrounded by the quadrilateral indicates the content of the production change adjustment operation (for example, in the case of the switching timing TM1 of the production program, "switching of the production program"). The above content about the display method is also the same for the pop-up display shown below. In addition, the first component assembly machine WM31a is the frontmost (upstreammost) component assembly machine WM3 among multiple (ten) component assembly machines WM3, and the first time period TZ1 is shorter than that of other component assembly machines WM3, so the first time period TZ1 is not displayed in the pop-up display in the upper section.

[0087] When the user Figure 4 When the mouse pointer is moved to the second component mounting machine WM32b in the diagram display shown, the display unit 42 executes Figure 6 The pop-up window in the lower stage is shown. In the pop-up window in the lower stage, the production program switching timing TM1, the loading and unloading timing TM2 of the item 30, the verification timing TM3 of the item 30, the first time zone TZ1 and the trial production time zone TZ3 are displayed for the second component mounting machine WM32b.

[0088] Likewise, when the user Figure 5 When the mouse pointer is moved to the first component mounting machine WM31d in the diagram display shown, the display unit 42 executes Figure 7 In addition, when the user Figure 5 When the mouse pointer is moved to the first component mounting machine WM31e in the diagram display shown, the display unit 42 executes Figure 7 The pop-up window in the lower section is shown. Figure 7 The pop-up window shown is the same as Figure 6 The pop-up window shown is displayed in the same manner, but for the sake of convenience, the display of the first time period TZ1 is omitted. Figure 7 The pop-up window in the lower section shows the second time period TZ2.

[0089] As mentioned above, Figure 5 The time required for the production changeover adjustment operation in the first component mounting machine WM31e shown is Figure 4 The user of the operating status display device 40 confirms Figure 7 The pop-up window display in the lower stage shown in the figure can identify that the cause of the problem in the production change adjustment work in the first component mounting machine WM31e is the failure of the substrate working machine WM0 (component mounting machine WM3).

[0090] The time from the removal timing TM21 to the installation timing TM22 is the time required for the loading and unloading operation of the article 30. Figure 7 The pop-up window in the upper part of the figure shows the time required for the loading and unloading operation of the article 30 of the first component assembly machine WM31d and the time required for the loading and unloading operation of the article 30 of the first component assembly machine WM31d. Figure 7 The time required for the loading and unloading operation of the article 30 of the first component assembly machine WM31e shown in the pop-up window display in the lower section is roughly the same. Therefore, in this case, the user of the operation status display device 40 can recognize that although a failure has occurred in the substrate operation machine WM0 (component assembly machine WM3), there is no problem with the loading and unloading operation of the article 30 itself.

[0091] When the user Figure 5 When the mouse pointer is moved to the first component mounting machine WM31h in the diagram display shown, the display unit 42 executes Figure 8 In addition, when the user Figure 5 When the mouse pointer is moved to the second component mounting machine WM32a in the diagram display shown, the display unit 42 executes Figure 8 The pop-up window in the lower section is shown. Figure 8 The pop-up window shown is the same as Figure 7 The pop-up window shown is displayed in the same way. However, Figure 8 The first time period TZ1 is shown in Figure 8 The pop-up window display in the lower section does not display the second time period TZ2 (the above-mentioned fault has not occurred).

[0092] Figure 8 The pop-up window in the lower part shows the time required for the loading and unloading operation of the article 30 of the second component assembly machine WM32a. Figure 8 The pop-up window in the upper section shows a sharp increase compared to the first component mounting machine WM31h. As mentioned above, Figure 5 The increase ratio of the time required for the production changeover adjustment operation of the second component mounting machine WM32a relative to the first component mounting machine WM31h is greatly increased compared with the component mounting machine WM3 from the first component mounting machine WM31e to the first component mounting machine WM31h. The user of the operation status display device 40 confirms Figure 8 The pop-up window shown in the figure shows that the cause of the problem in the production changeover adjustment work in the second component mounting machine WM32a can be identified as the time required for the loading and unloading work of the article 30.

[0093] In any of the above-mentioned methods, the display unit 42 can also display the scheduled time period TT0 and the implementation time period TP0 of the production change adjustment operation in a comparable manner. The scheduled time period TS0 can be calculated based on the production program of the substrate operation machine WM0 by the drive control. In this case, the acquisition unit 41 acquires the scheduled time period TS0 of the production change adjustment operation calculated based on the production program of the substrate operation machine WM0 by the drive control.

[0094] The acquisition unit 41, for example, refers to the production program used in the first production and the production program used in the second production to acquire the difference information between the article 30 used in the first production and the article 30 used in the second production. The difference information includes information related to the article 30 used only in the first production, the article 30 used only in the second production, and the article 30 used in both the first production and the second production and equipped at a changed position. The acquisition unit 41 can calculate the scheduled required time for the loading and unloading operation based on the difference information. Similarly, the acquisition unit 41 can also calculate the scheduled required time for other production change adjustment operations, and can acquire the scheduled time period TS0 based on the calculated scheduled required time.

[0095] The display unit 42 can, for example, display the scheduled time period TS0 and the implementation time period TP0 of the production change adjustment operation side by side in accordance with the start time. Thus, the user of the operation status display device 40 can easily compare the scheduled time period TS0 and the implementation time period TP0 of the production change adjustment operation. Figure 4 as well as Figure 5 In the diagram shown, for the convenience of illustration, the scheduled time period TS0 and the implementation time period TP0 of the production change adjustment operation are recorded for the second component assembly machine WM32b. Similarly, the display unit 42 can also display the scheduled time period TS0 and the implementation time period TP0 of the production change adjustment operation for other component assembly machines WM3 (substrate operation machine WM0).

[0096] In any of the above-mentioned methods, the display unit 42 can also display the carrying-in waiting time TW1 and the carrying-out waiting time TW2 together with the implementation time period TP0 of the target work machine TG0. The carrying-in waiting time TW1 refers to the waiting time from the completion of the production change adjustment operation in the target work machine TG0, which is one of the plurality of substrate work machines WM0, until the substrate 90 is carried in from the substrate work machine WM0 on the upstream side of the target work machine TG0 to the target work machine TG0. The carrying-out waiting time TW2 refers to the waiting time from the completion of the production change adjustment operation in the target work machine TG0 until the substrate 90 can be carried out to the substrate work machine WM0 on the downstream side of the target work machine TG0.

[0097] In this case, the acquisition unit 41 acquires the carry-in waiting time TW1 and the carry-out waiting time TW2 of the target work machine TG0. The target work machine TG0 may also be any substrate work machine WM0 among the plurality of substrate work machines WM0. In addition, the target work machine TG0 may also be any component assembly machine WM3 among the plurality of (ten) component assembly machines WM3. In the present embodiment, the acquisition unit 41 uses each component assembly machine WM3 of the plurality of (ten) component assembly machines WM3 as the target work machine TG0, and acquires the carry-in waiting time TW1 and the carry-out waiting time TW2.

[0098] The display unit 42 can display the carry-in waiting time TW1 and the carry-out waiting time TW2 for each of the plurality of (ten) component assembly machines WM3. Thus, the user of the operation status display device 40 can easily recognize the carry-in waiting time TW1 and the carry-out waiting time TW2. Figure 4 as well as Figure 5 In the graph display shown, for the sake of illustration, the carry-in waiting time TW1 and the carry-out waiting time TW2 are displayed for the second component mounting machine WM32b. Similarly, the display unit 42 can also display the carry-in waiting time TW1 and the carry-out waiting time TW2 for other component mounting machines WM3 (substrate working machine WM0).

[0099] 1-3-3. Judgment Unit 43

[0100] The judgment unit 43 judges that the production change adjustment operation is appropriate when the excess time obtained by subtracting the required time of the production change adjustment operation in the predetermined time period TT0 from the required time of the production change adjustment operation in the implementation time period TP0 is less than the predetermined threshold value. In addition, the judgment unit 43 judges that the production change adjustment operation is inappropriate when the excess time is greater than the predetermined threshold value. Figure 3 Step S12 shown).

[0101] In the same manner as described above, the acquisition unit 41 acquires the scheduled time period TS0 for the production changeover and adjustment operation calculated by the drive control for the production program of the substrate operation machine WM0. In addition, the predetermined threshold value can be set, for example, as a time obtained by adding a predetermined ratio (for example, 10% to 50% of the required time) to the time required for the production changeover and adjustment operation in the scheduled time period TT0. Furthermore, the predetermined threshold value can also be set, for example, as a time obtained by adding a certain time to the time required for the production changeover and adjustment operation in the scheduled time period TT0.

[0102] In the embodiment in which the operating status display device 40 includes the determination unit 43, the display unit 42 can display the appropriateness of the production change adjustment operation determined by the determination unit 43. Figure 5In the graph shown, it is assumed that the time of replacement work in the first component mounting machine WM31e and the second component mounting machine WM32a exceeds the predetermined threshold. In this case, the judgment unit 43 judges that the production change adjustment work is inappropriate for the first component mounting machine WM31e and the second component mounting machine WM32a. Figure 5 The graph display shown indicates that the production changeover adjustment work of the first component mounting machine WM31e and the second component mounting machine WM32a is inappropriate.

[0103] In addition, the judgment unit 43 can select the substrate work machine WM0 with the longest overtime from the plurality of substrate work machines WM0. In this case, when the display unit 42 displays the implementation time period TP0 of each substrate work machine WM0 of the plurality of substrate work machines WM0 in a graph, it can clearly show that the substrate work machine WM0 selected by the judgment unit 43 is the bottleneck.

[0104] For example, it is assumed that among the plurality of (ten) component assembly machines WM3, the component assembly machine WM3 with the longest overtime is the second component assembly machine WM32a. In this case, the judgment unit 43 selects the second component assembly machine WM32a. Thus, when the display unit 42 displays the implementation time period TP0 of each component assembly machine WM3 of the plurality of (ten) component assembly machines WM3 in a graph, it is clearly shown that the second component assembly machine WM32a selected by the judgment unit 43 is the bottleneck. In addition, if Figure 5 As shown, the display unit 42 can clearly indicate that the second component mounting machine WM32a is a bottleneck by the symbol CD0, and can also clearly indicate it by text information (bottleneck).

[0105] Furthermore, the determination unit 43 can determine that the stagnation period SP0 has occurred in the production changeover adjustment operation when a predetermined condition is satisfied. The predetermined condition is that after the last substrate 90 of the substrate product 900 produced in the first production in the last substrate operation machine WM0 among the plurality of substrate operation machines WM0 is unloaded, the first predetermined number of substrates 90 of the substrate product 900 produced in the second production in the first substrate operation machine WM0 among the plurality of substrate operation machines WM0 is loaded or unloaded.

[0106] For example, the time when the last substrate 90 of the substrate product 900 produced in the first production is unloaded in the second component assembly machine WM32b, which is the last one (most downstream side) among the plurality of (ten) component assembly machines WM3, is set as time TK1. In addition, the time when the first predetermined number of substrates 90 of the substrate product 900 produced in the second production is moved in or out of the first component assembly machine WM31a, which is the first one (most upstream side) among the plurality of (ten) component assembly machines WM3, is set as time TK2. Figure 4 In the graph display shown, time TK2 comes before time TK1. Therefore, in this case, the above-mentioned predetermined condition is not satisfied.

[0107] Fig. 9 Another example of a graph display based on the display unit 42 is shown. Figure 4 However, in Fig. 9 In the example, the time T31 indicated at the front end of the arrow indicating the implementation time period TP0 is represented by the time T31b, and the time T33 is represented by the time T33b. Figure 4 Therefore, Fig. 9 In the graph shown, time TK2 comes after time TK1. Therefore, in this case, the predetermined condition is satisfied, and the determination unit 43 determines that a stagnation period SP0 has occurred in the production changeover adjustment work.

[0108] In this case, when the display unit 42 displays the implementation time period TP0 of each of the plurality of substrate operation machines WM0 in a graph, it is clearly shown that a stagnation period SP0 has occurred during the production change adjustment operation. That is, when the display unit 42 displays the implementation time period TP0 of each of the plurality of (ten) component assembly machines WM3 in a graph, it is clearly shown that a stagnation period SP0 has occurred during the production change adjustment operation. In addition, Fig. 9 As shown, the display unit 42 can display the stagnation period SP0 of the production changeover adjustment work, and can also clearly indicate it through text information (there is a stagnation period SP0 in the production changeover adjustment work).

[0109] 2. Others

[0110] The operating status display device 40 may also include a proposal unit that proposes improvements to the production change adjustment operation when the judgment unit 43 determines that the production change adjustment operation is inappropriate. In this case, the display unit 42 may display the proposed items proposed by the proposal unit. For example, Figure 6 As shown in the pop-up window display, the disassembly timing TM21 of the article 30 in the first component assembly machine WM31a at the front (most upstream side) is later than the start time (time T48) of the production change adjustment operation in the second component assembly machine WM32b at the end (most downstream side). That is, the start time of the loading and unloading operation of the article 30 in the first component assembly machine WM31a is extremely late.

[0111] In this case, the proposal department can make a proposal in a manner to improve the loading and unloading operation of the article 30 in the first component mounting machine WM31a. For example, the proposal department can propose to prepare in advance the article 30 to be used in the second production. In addition, the proposal department can also make a proposal in a manner to verify the work of the operator who performs the loading and unloading operation of the article 30 in the first component mounting machine WM31a.

[0112] Furthermore, for example, Figure 8 The pop-up window in the lower part shows the time required for the loading and unloading operation of the article 30 of the second component assembly machine WM32a. Figure 8 That is, the loading and unloading operations of the articles 30 are not balanced among the plurality of (ten) component mounting machines WM3.

[0113] In this case, the proposal unit can make proposals in a manner that balances the loading and unloading operations of the article 30 in the plurality of (ten) component mounting machines WM3. For example, the proposal unit can make proposals in a manner that verifies whether the article 30 scheduled to be equipped in the second component mounting machine WM32a can be equipped in the second component mounting machine WM32a.

[0114] In addition, in this specification, the production change adjustment operation in the component assembly machine WM3 is used as an example for explanation, but it is not limited to this. The display unit 42 can display the implementation time period TP0 of various production change adjustment operations in the substrate operation machine WM0. In addition, the display unit 42 can also simultaneously display the implementation time period TP0 of multiple production change adjustment operations in the substrate operation machine WM0. For example, the display unit 42 can simultaneously display the implementation time period TP0 of the production change adjustment operation in the printing machine WM1, the component assembly machine WM3, and the reflow oven WM5. Furthermore, the display unit 42 can also display various information related to the production change adjustment operation other than specific information.

[0115] 3. Operation status display method

[0116] The contents described above about the operating status display device 40 are also the same for the operating status display method. Specifically, the operating status display method includes an acquisition process and a display process. The acquisition process is equivalent to the control performed by the acquisition unit 41. The display process is equivalent to the control performed by the display unit 42. In addition, the operating status display method can include a judgment process. The judgment process is equivalent to the control performed by the judgment unit 43.

[0117] 4. An example of the effect of the embodiment

[0118] The operation status display device 40 includes an acquisition unit 41 and a display unit 42. Thus, the operation status display device 40 can display in a time series a graph of the implementation time period TP0 of the production change adjustment work of the substrate production equipment PF0 that produces the substrate product 900. The above contents about the operation status display device 40 are also the same for the operation status display method.
