Mode for Carrying Out the Invention

[0010] 〔Embodiment 1〕 Hereinafter, an embodiment of the present disclosure will be described in detail. FIG. 1 shows an overview of the processing status display device 1 according to the present disclosure. The processing status display device 1 continuously displays the production quantity for each lot as the processing status in one or a plurality of manufacturing devices 101 among the manufacturing devices 101A, 101B, …, 101X included in the production line 110 (hereinafter, simply referred to as the manufacturing device 101 when there is no need for distinction). The manufacturing device 101 can be referred to as a processing device. Also, the production quantity can be referred to as the number of products for which processing has been performed in the processing device.

[0011] When the processing status display device 1 displays the production quantity of the manufacturing device 101, by continuously displaying it for each lot, the administrator can be made to recognize the appropriateness of the production status for each lot.

[0012] Hereinafter, the processing status display device 1 that displays the processing status in the manufacturing device 101 included in the production line 110 will be described as an example, but the processing status display device 1 according to the present disclosure is not limited to this. Any device that performs processing in lot units may be used, for example, an inspection device or the like.

[0013] 〔Processing Status Display Device 1〕 Next, with reference to FIG. 2, the processing status display device 1 will be described. FIG. 2 is a functional block diagram showing the main configuration of the processing status display device 1.

[0014] As shown in FIG. 2, the processing status display device 1 includes a control unit 10, an acquisition unit 20, and a monitor 30. The control unit 10 further includes a reset unit 11 and a graph display unit 12.

[0015] The acquisition unit 20 acquires data related to the production quantity from the manufacturing apparatus 101 that is the target for displaying the processing status, and transmits it to the control unit 10.

[0016] In addition, the acquisition unit 20 acquires information related to the lot of the manufactured product being processed, and transmits it to the control unit 10. Here, a lot is a unit for managing manufactured products. More specifically, a lot is the minimum unit of the production quantity and the shipment quantity of products manufactured under the same conditions. The number of items in one lot is not particularly determined, and for example, 1 lot = 50 items may be used, or 1 lot = 1000 items may be used.

[0017] The control unit 10 includes the reset unit 11 and the graph display unit 12 as described above, and continuously displays on the monitor 30 graphs showing the production quantity in the manufacturing apparatus 101 acquired by the acquisition unit for each lot.

[0018] Specifically, the reset unit 11 uses the information related to the lot acquired by the acquisition unit 20 to reset the production quantity for each lot, and notifies the graph display unit 12.

[0019] The graph display unit 12 uses the production quantity notified from the reset unit 11 to display a graph showing the production quantity on the monitor 30.

[0020] FIG. 3 shows an example of the graph that the graph display unit 12 displays on the monitor 30. In FIG. 3, a line graph showing time on the horizontal axis and production quantity on the vertical axis is displayed.

[0021] As described above, the production quantity is reset for each lot by the reset unit 11. Therefore, in the graph shown in FIG. 3, the timing when the production quantity becomes 0 (zero) means that the lot has been changed. In the graph shown in FIG. 3, the production quantities from the lot of lot number 1 to the lot of lot number 6 are shown.

[0022] Since the graph shown in Fig. 3 is a line graph, the administrator can recognize the manufacturing status for each lot just by glancing at this graph. For example, since the slope of the graph indicates the manufacturing tact (number of manufactured products / unit time), it can be easily recognized that if the slope is steep, the number of manufactured products per unit time is large, and if the slope is gentle, the number of manufactured products per unit time is small, etc.

[0023] Also, by following the trend of the slope, the trend of the capabilities of the manufacturing apparatus 101 can be grasped. That is, if the angle is approaching vertical, it can be recognized that the production capacity is improving. On the other hand, if the angle is approaching horizontal, it can be recognized that the production capacity is deteriorating.

[0024] Also, in the stopped state, since the number of manufactured products does not increase, the graph becomes horizontal.

[0025] Also, by connecting the starting point and the ending point, the production capacity of the manufacturing apparatus 101 including stops can be grasped.

[0026] Also, in the graph shown in Fig. 3, the operating status indicating whether it is in the operating state or the stopped state, and the reason for stopping in the stopped state are indicated by line types. In the graph shown in Fig. 3, a solid line indicates that it is in the operating state, and otherwise it indicates that it is in the stopped state. Also, examples of reasons for stopping include inspection stop, chocolate stop, doka stop, OPC, changeover, and other stops. These reasons for stopping are examples when assuming a manufacturing apparatus for manufacturing electronic components.

[0027] (1) An inspection stop is a stop for inspection.

[0028] (2) A chocolate stop refers to, for example, the case of stopping for the following reasons.

[0029] · Sample set mistake (product jumps out of the transfer lane and sensor operates) · Adsorption or chucking mistake in the case of soft workpieces · Wear of consumables such as adsorption pads · Failure in positioning with an accuracy of 10 μm (3) “Doka stop” refers to the case of stopping for the following reasons, for example.

[0030] · Equipment failure (motor failure, solenoid valve failure, chain break, heater shutdown) (4) “OPC (Operator Call)” refers to the case of stopping for the following reasons, for example.

[0031] · Material depletion (adhesive, paint, etc.) · Consumable depletion (carrier film, base paper, etc.) · Input product stock is empty, and the recovered product stock is full · Sub-member dustbin is full (5) “Changeover” refers to the case of stopping for the following reasons, for example.

[0032] · Tool change (when running a different product) (6) Examples of other stops include operator shift change.

[0033] In the graph shown in Figure 3, the dashed line indicates “other stops”, the thick line indicates “OPC”, the thick dashed line indicates “inspection stop”, and the dotted dashed line indicates “changeover”. Here, the reasons are explained in association with each line type, but the reasons may also be associated with each color instead of the line type. For example, red can indicate “Doka stop”, yellow can indicate “Choco stop”, green can indicate “inspection stop”, blue can indicate “OPC”, …, and they can be associated in this way.

[0034] A method of generating a graph with different line types, colors, etc. for each lot or for each stop reason is possible, for example, by the following procedure.

[0035] When the lot of lot number 1 ends and the manufacturing apparatus 101 stops operating, the operator causes the barcode of the lot card indicating lot number 1 to be read and inputs the end of the lot of lot number 1. The lot card is, for example, a card on which a barcode indicating the lot number or the like is printed. From the apparatus in which the end of the lot of lot number 1 has been input, the processing status display apparatus 1 recognizes the end of the lot of lot number 1, and the reset unit 11 resets the production quantity. Here, the graph display unit 12 changes the line type or color of the graph and starts creating a graph with a production quantity of 0.

[0036] Thereafter, the operator causes the barcode of the lot card of the lot of lot number 2 to be read and inputs the start of the lot of lot number 2. From the apparatus in which the start of the lot of lot number 2 has been input, the processing status display apparatus 1 recognizes the start of the lot of lot number 2. When the manufacturing apparatus 101 starts operating, the manufacturing apparatus 101 acquires the production quantity, changes the line type or color of the graph, and generates a graph according to the production quantity.

[0037] In this way, the graph display unit 12 may display the graph with different display forms according to the operating status of the manufacturing apparatus 101. By making the display forms different, the administrator can list and recognize the processing status in the manufacturing apparatus 101.

[0038] Also, when the operating status of the manufacturing apparatus 101 is in a stopped state, the graph display unit 12 may display the graph with different display forms according to the reason for the stop. By making the display forms of the graph different according to the reason for the stop, the administrator can list and recognize the reason for the stop.

[0039] The monitor 30 is a display device that displays the graph generated by the graph display unit 12.

[0040] The graph display unit 12 may display not only the production quantity but also a graph serving as an index for manufacturing. The graph serving as an index may be generated, for example, from past production quantities.

[0041] Referring to FIG. 4, an example of generating a graph serving as an indicator will be described. 401 in FIG. 4 is a graph showing the production quantities for lots of past lot number A, lot number B, and lot number C. A straight line connecting the starting point A1 and the ending point A2 of the graph showing the production quantity of the lot of lot number A is defined as an indicator candidate line 411. A straight line connecting the starting point B1 and the ending point B2 of the graph showing the production quantity of the lot of lot number B is defined as an indicator candidate line 412. A straight line connecting the starting point C1 and the ending point C2 of the graph showing the production quantity of the lot of lot number C is defined as an indicator candidate line 413.

[0042] As shown in 402 of FIG. 4, the graph display unit 12 defines a line showing the average of the indicator candidate line 411, the indicator candidate line 412, and the indicator candidate line 413 as an indicator line 421. Then, the indicator line 421 is displayed on the monitor 30 together with the graph showing the production quantity.

[0043] FIG. 5 shows the indicator line 421 and a graph 500 showing the production quantity. The graph 500 here does not show the distinctions by the above-mentioned line types and color-coding. By simultaneously displaying the indicator line 421 and the graph 500 showing the production quantity, it is possible to quickly recognize the operating state with respect to the indicator, the overtime 501, the shortage quantity 502, the production capacity 503, etc.

[0044] As described above, the graph display unit 12 displays, for each lot, a graph serving as an indicator together with a graph showing the time-series data of the production quantity. Thereby, the administrator can be made to recognize the difference from the indicator.

[0045] Also, the graph displayed by the graph display unit 12 is a line graph, and the graph display unit 12 generates and displays a graph serving as an indicator from the time-series data of the quantities of a plurality of lots of the same product processed in the past. By using the past time-series data, an appropriate graph serving as an indicator can be displayed.

[0046] In addition, the graph display unit 12 may display, as an index graph, a graph of the slope indicating the processing speed in the operating state for the same lot. By using the slope indicating the processing speed in the operating state, a graph in the case where no inconvenience has occurred can be displayed as the index graph.

[0047] Next, with reference to FIG. 6, the processing flow in the processing status display device 1 will be described. FIG. 6 is a flowchart showing the processing flow in the processing status display device 1.

[0048] As shown in FIG. 6, in the processing status display device 1, the acquisition unit 20 acquires the number of processed items, that is, the production quantity, in the manufacturing device 101 (S101, acquisition step). Next, the reset unit 11 determines whether there has been a lot update in the processing in the manufacturing device 101 (S102). If there is no lot update (NO in S102), the graph display unit 12 directly generates a graph showing the production quantity from the production quantity acquired by the acquisition unit 20 and displays it on the monitor 30. On the other hand, if it is determined in step S102 that there has been a lot update (YES in S102), the reset unit 11 resets the production quantity (S103, reset step). Then, it returns to step S501, acquires the production quantity in the manufacturing device 101 (S101), and displays a graph showing the production quantity on the monitor 30 based on the acquired production quantity (S104, graph display step).

[0049] As described above, the processing status display device 1 according to the present embodiment includes an acquisition unit 20 that acquires the production quantity, which is the number of target items processed in the manufacturing device 101 as a certain processing device. It also includes a reset unit 11 that resets the quantity to zero for each lot of the target items. Furthermore, it includes a graph display unit 12 that continuously displays, for each lot, a graph showing the time-series data of the quantity corresponding to a plurality of lots.

[0050] As a result, the number of target products processed in the manufacturing apparatus 101 is reset to zero for each lot, and a continuous graph is displayed for each lot, so that the administrator can grasp the situation regarding the processing for each lot.

[0051] 〔Embodiment 2〕 Other embodiments of the present disclosure will be described below. For convenience of explanation, members having the same functions as the members described in the above embodiment are denoted by the same reference numerals, and the description thereof will not be repeated.

[0052] In the above-described embodiment, the configuration for displaying the processing status of one or a plurality of manufacturing apparatuses 101 included in one manufacturing line 110 has been described. The processing status display device 1 according to the present embodiment acquires the production numbers of manufacturing apparatuses 101 (for example, 101A, 102A, 103A) that process the same target and are included in a plurality of manufacturing lines 110 (for example, 110A, 110B, 110C), and superimposes and displays them.

[0053] By superimposing and displaying the production numbers in a plurality of manufacturing apparatuses that process the same target product, it is possible to easily determine the quality of a specific manufacturing apparatus.

[0054] Specifically, referring to FIG. 8, FIG. 8 shows a graph showing the production numbers in a plurality of manufacturing apparatuses superimposed. For example, it is assumed that 801 shown in FIG. 8 indicates the production number in the manufacturing apparatus 101A, and 802 indicates the production number in the manufacturing apparatus 102A. Since the manufacturing apparatus 101A and the manufacturing apparatus 102A perform the same process on the same target, it is desirable that the production numbers are also the same. However, when there is a deviation in the graph showing the production numbers, as in 801 and 802 in FIG. 8, it is clear that one of the manufacturing apparatuses 101 is malfunctioning. That is, it is obvious that the production number per unit time of the manufacturing apparatus 101A is larger than the production number per unit time of the manufacturing apparatus 102A, and it can be easily recognized that the manufacturing apparatus 102A is not in good condition.

[0055] As described above, when there are a plurality of manufacturing apparatuses 101 that process the same target product, the graph display unit 12 may simultaneously display graphs showing the time-series data of the production numbers of the target products processed by each of the plurality of manufacturing apparatuses 101.

[0056] Thereby, the administrator can list and recognize the states of each of the plurality of manufacturing apparatuses 101. Therefore, it is possible to easily discover the manufacturing apparatus 101 that is considered to be malfunctioning.

[0057] 〔Example of Realization by Software〕 The functions of the processing status display device 1 (hereinafter referred to as the "device") are programs for causing a computer to function as the device, and can be realized by programs for causing a computer to function as each control block (particularly each part included in the control unit 10) of the device.

[0058] In this case, the above device includes a computer having at least one control device (for example, a processor) and at least one storage device (for example, a memory) as hardware for executing the above program. By executing the above program with this control device and storage device, each function described in each of the above embodiments is realized.

[0059] The above program may be recorded on one or more computer-readable recording media, not temporarily. This recording medium may or may not be provided in the above device. In the latter case, the above program may be supplied to the above device via any wired or wireless transmission medium.

[0060] Also, part or all of the functions of each of the above control blocks can also be realized by a logic circuit. For example, an integrated circuit in which a logic circuit functioning as each of the above control blocks is formed is also included in the scope of the present disclosure. In addition to this, for example, it is also possible to realize the functions of each of the above control blocks by a quantum computer.

[0061] The invention according to the present disclosure has been described above based on the drawings and examples. However, the invention according to the present disclosure is not limited to each of the above-described embodiments. That is, various modifications are possible within the scope shown in the present disclosure, and embodiments obtained by appropriately combining the technical means disclosed in different embodiments are also included in the technical scope of the invention according to the present disclosure.
