[0009] Before describing the embodiments of the present disclosure, we will briefly explain the problems with conventional devices. In production lines that include manual processes in which workers attach parts to workpieces and tighten screws, it is difficult to collect detailed information about the work performance of workers, and there is room for further improvement in order to perform accurate process management on production lines with diverse configurations. Therefore, an object of the present disclosure is to provide a terminal device, a display method, and a display program that can record detailed information about the work performance of workers.

[0010] An embodiment of the present disclosure will be described in detail below with reference to the drawings. The configurations, shapes, etc. described below are examples for explanatory purposes and can be modified as appropriate depending on the specifications of the production system, production line, terminal device, and production device. In the following, a component mounting line, a component placement line, and an assembly line that mount components, etc., on boards to produce mounted boards will be described as examples of production lines. In the following, corresponding elements in all drawings will be assigned the same reference numerals, and duplicated explanations will be omitted.

[0011] FIG. 1 is an explanatory diagram of the configuration of a component mounting system 1 according to an embodiment of the present disclosure. First, with reference to FIG. 1, the configuration of component mounting system 1, which is a production system, will be described. Component mounting system 1 includes a component mounting line L1, a component placement line L2, and an assembly line L3. Component mounting line L1 is configured such that a plurality of production devices connected to an intra-mounting line communication network 2 are controlled by a mounting line management device 3. Component placement line L2 is configured such that a plurality of production devices connected to an intra-mounting line communication network 4 are controlled by a placement line management device 5.

[0012] Assembly line L3 is provided with multiple work areas S1 to S5 where workers work on workpieces such as circuit boards. FIG. 2 is an explanatory diagram of the configuration of each work area. As shown in FIG. 2, each of work areas S1 to S5 is provided with a terminal device T, such as a tablet PC (Personal Computer). Assembly line L3 is provided with an assembly line management device 6 equipped with a wireless communication unit 6a that wirelessly communicates with terminal device T. The mounting line management device 3, placement line management device 5, and assembly line management device 6 are connected to a communication network 7. Furthermore, an integrated management device 8 is connected to communication network 7. Terminal device T does not need to be provided at each of work areas S1 to S5, but may be carried by a worker. Terminal device T does not have to be a tablet PC as long as it has input and display functions, and may be a wearable device, such as glasses or a watch.

[0013] 1 includes one each of component mounting line L1, component placement line L2, and assembly line L3, but the component mounting system 1 is not limited to this configuration. The component mounting system 1 may include two or more each of component mounting line L1, component placement line L2, and assembly line L3, or may not include any of the lines.

[0014] In Fig. 1, component mounting line L1 has production devices such as loader device M1, printing device M2, component mounting devices M3 to M5, reflow device M6, and unloader device M7 connected in series from the upstream side (left side of the page) to the downstream side (right side of the page) in the board conveyance direction. Loader device M1 receives (arrow a) a board B (see Fig. 2) carried into component mounting line L1 and supplies the received board B to downstream production devices. Hereinafter, unless otherwise specified, the term "board B" will be used to refer to a board in an intermediate state, such as when solder is printed or when components or odd-shaped components are mounted or attached.

[0015] The printing device M2 performs a solder printing operation to screen-print solder for joining components onto the board B. The component mounting devices M3 to M5 perform a component mounting operation to mount components P (see FIG. 2) onto the board B on which the solder has been printed. The reflow device M6 performs a reflow operation to heat the board B to melt the solder and then harden it, solder-joining the electrodes of the board B to the terminals of the components P. The unloader device M7 collects the board B transported from the upstream side.

[0016] In Figure 1, component mounting line L2 has production devices such as a loader device M8, an odd-shaped component mounting device M9, a local soldering device M10, and an unloader device M11 connected in series from upstream to downstream in the board transport direction. Each production device is equipped with a board transport mechanism that transports board B. The board transport mechanism uses a carry-in device equipped with a conveyor to load board B from the upstream side and transport it to the work position, and then uses a carry-out device equipped with a conveyor to unload board B downstream after work by the work device has been completed. Note that the load-in device and carry-out device do not need to be separate devices, and a single conveyor may perform both load and unload.

[0017] Loader device M8 supplies board B transferred from unloader device M7 of component mounting line L1 (arrow b) to downstream production equipment using its built-in unloading device. In odd-shaped component mounting device M9, its built-in loading device loads board B, and its built-in working device performs odd-shaped component mounting work, attaching (inserting) odd-shaped components C (see Figure 2) such as sockets and connectors to board B, and its built-in unloading device unloads board B after the work. In local soldering device M10, its built-in loading device loads board B, and its built-in working device performs local soldering work, dipping molten solder into only the terminals of odd-shaped components C mounted on board B, and its built-in unloading device unloads board B after the work. Unloader device M11 collects board B transported from upstream using its built-in loading device.

[0018] In Fig. 1, the loader device M8 and the unloader device M11 are equipped with a recognition unit R that recognizes identification information Q (see Fig. 2), such as a one-dimensional code, a two-dimensional code, or RFID (Radio Frequency Identification) attached to the board B (workpiece). The recognition unit R of the loader device M8 recognizes the identification information Q when the board B is transferred to the odd-shaped component mounting device M9. The recognition unit R of the unloader device M11 recognizes the identification information Q when the board B is retrieved from the local soldering device M10.

[0019] Information about the board B (work) recognized by the recognition unit R is transmitted to the mounting line management device 5 via the mounting line intra-communication network 4. Note that it is not necessary for both the loader device M8 and the unloader device M11 to be equipped with the recognition unit R. In other words, it is sufficient that at least one of the loader device M8, which is a carry-in device, and the unloader device M11, which is an unloading device, is equipped with the recognition unit R that recognizes the identification information Q attached to the board B (work).

[0020] 2, each of work areas S1 to S5 installed on assembly line L3 is provided with a workbench 9 on which a worker places a board B (workpiece) and works. Each workbench 9 is provided with a terminal device T and a reader 10 that the worker uses when working on the board B. The reader 10 is equipped with a reading unit (not shown) that recognizes identification information Q attached to the board B.

[0021] The identification information Q recognized by the worker operating the reader 10 is wirelessly transmitted to the assembly line management device 6. Note that the reader 10 installed on the workbench 9 may be configured to automatically recognize the identification information Q attached to the board B.

[0022] In FIG. 1, a board B (workpiece) collected by unloader device M11 of component mounting line L2 is transported to work area S1 at the head of assembly line L3 (arrow c). At each of work areas S1 to S5, workers perform production work (operations) on the board B as instructed by terminal device T, and then transfer the board B to a downstream work area. After completing work at work area S5 at the end, the board B is transported out of assembly line L3 (arrow d). Note that assembly line L3 may also perform production work on workpieces or members that have been processed on a production line other than component mounting line L2.

[0023] The number of work areas S1 to S5 installed on the assembly line L3 is not limited to five, and may be one or six or more. Furthermore, the terminal device T and the reader 10 do not need to be installed in all work areas S1 to S5; they may be installed in at least one of the work areas S1 to S5. Similarly to the component mounting line L2, the loader device M8 equipped with the recognition unit R may be installed upstream of the first work area S1, and the unloader device M11 equipped with the recognition unit R may be installed downstream of the last work area S5. In this case, the identification information Q recognized by the recognition unit R is transmitted to the assembly line management device 6 wirelessly or via a wired network (not shown).

[0024] Next, referring to Fig. 3, a configuration relating to process management that collects the history of production work by production equipment and workers, among the functions of the component mounting system 1, will be described. Fig. 3 is a block diagram showing the configuration relating to process management of the component mounting system 1 according to an embodiment of the present disclosure. Fig. 3 mainly describes the collection of the history of production work on the component mounting line L1 and the component placement line L2. The integrated management device 8 includes a management memory unit 11, a history collection unit 12, an analysis processing unit 13, and a management communication unit 14. The management memory unit 11 is a storage device that stores production history data 11a and the like.

[0025] The management communication unit 14 transmits and receives various information to and from the mounting line management device 3, the placement line management device 5, and the assembly line management device 6 via the communication network 7. The history collection unit 12 collects production work history information of the production devices, etc. collected by the mounting line management device 3, the placement line management device 5, and the assembly line management device 6, and stores it in the management storage unit 11 as production history data 11a. The analysis processing unit 13 analyzes bottlenecks, efficiency, and the like of the production process based on the collected production history data 11a. Note that a separate system may be provided that includes the analysis processing unit 13 and a display unit that displays the analyzed bottlenecks and efficiency of the production process.

[0026] 3, the mounting line management device 3 that manages the component mounting line L1 includes a mounting storage unit 21, a mounting history processing unit 22, and a mounting communication unit 23. The mounting storage unit 21 is a storage device that stores mounting history data 21a and the like. The mounting communication unit 23 transmits and receives various information to and from the integrated management device 8, the mounting line management device 5, and the assembly line management device 6 via the communication network 7. The mounting history processing unit 22 collects performance data such as the start time, end time, and error information of production work from the production devices provided on the component mounting line L1, and stores the collected performance data 21a in the mounting storage unit 21. The mounting history processing unit 22 also transmits the collected mounting history data 21a to the integrated management device 8.

[0027] The mounting line management device 5, which manages the component mounting line L2, includes a mounting memory unit 31, a management setting unit 32, an information collection unit 33, a production time calculation unit 34, an input unit 35, a display unit 36, and a mounting communication unit 37. The mounting memory unit 31 is a storage device that stores production device data 31a, standard time data 31b, mounting history data 31c, and the like. The mounting communication unit 37 transmits and receives various information to and from the integrated management device 8, the mounting line management device 3, and the assembly line management device 6 via the communication network 7. The input unit 35 is an input device such as a keyboard, touch panel, or mouse, and is used to input operation commands and data. The display unit 36 ​​is a display device such as a liquid crystal panel that displays various data stored in each memory unit and also displays various information such as a management method setting screen for operation by the input unit 35.

[0028] 3, production equipment data 31a stores information identifying the production equipment equipped on component mounting line L2, the connection order, the work content performed by the production equipment, etc. Standard time data 31b stores the standard work time (standard work time) for each production process, including a carry-in process in which board B (work) is carried in by a carry-in device, a work process in which odd-shaped components are mounted on board B by a work device and local soldering work is performed, and a carry-out process in which board B is carried out by a carry-out device. Management setting unit 32 sets which management method to use: integrated management in which the production processes are managed as a group, or individual management in which each production process is managed individually.

[0029] 4, an example of a management method setting screen 40 that the management setting unit 32 displays on the display unit 36 ​​will be described. FIG. 4 is a diagram showing an example of the management method setting screen 40 displayed on the display unit 36 ​​provided in the placement line management device (process management device) 5. The management method setting screen 40 displays an "Item Name" setting frame 41, a "Production Line Name" setting frame 42, a "Management Method" setting frame 43, a "Production Device for Information Collection" setting frame 44, and a "Decide" button 45. In the "Item Name" setting frame 41, the worker operates the input unit 35 to input the name of the item to be produced. In the "Production Line" setting frame 42, the worker operates the input unit 35 to input the production line for which the management method is to be set. In this example, "B1" is set as the item name and "L2" as the production line name.

[0030] In the "Management method" setting frame 43, the worker operates the input unit 35 to select a radio button 43a, thereby setting either "integrated management" or "individual management" as the management method. In this example, "integrated management" is set. In the "Production equipment to be collected information" setting frame 44, the worker operates the input unit 35 to select a setting button 44a, thereby selecting and setting the production equipment to be collected information. In this example, of the production equipment equipped in the component mounting line L2, the loader device M8 and unloader device M11 are selected. Note that when "individual management" is set in the "Management method" setting frame 43, all production equipment is automatically selected. When the worker operates the "Enter" button 45 using the input unit 35, the management setting unit 32 sets the conditions set in the management method setting screen 40 as the management method.

[0031] 3, the information collection unit 33 collects work information based on the management method set by the management setting unit 32. Specifically, in the case of integrated management, the information collection unit 33 collects work information from at least one device among multiple devices in the production process. In the case of individual management, the information collection unit 33 collects work information from each device in the production process. The collected work information is stored in the wearing storage unit 31 as wearing history data 31c.

[0032] Furthermore, when the recognition unit R provided in the loader device M8 or unloader device M11 recognizes the identification information Q attached to the board B (workpiece), the information collection unit 33 collects the information of the board B recognized by the recognition unit R. In the case of integrated management, the production time calculation unit 34 calculates (estimates) the production time (production completion time) at which the production process was performed for each board B from the time at which the information collection unit 33 collected the information of the board B and the standard operation time included in the standard time data 31b. In the case of individual management, the production time calculation unit 34 calculates (estimates) the production time at which the production process was performed for each board B from the collected operation information from each device and the standard operation time included in the standard time data 31b. The calculated production time is stored in the mounting history data 31c.

[0033] An example of individual management will now be described with reference to FIG. 5A. FIG. 5A is a diagram illustrating an example of individual management by a mounting line management device (process management device) 5. In individual management, the start or end times of the carry-in process, work process, and carry-out process are collected from each production device. In the loader device M8, the carry-out process starts at time T11 and ends at time T12. Here, time T11 is the time when the conveyor provided in the loader device M8 starts to move, and time T12 is the actual time when the conveyor stops moving. In the loader device M8, the recognition unit R recognizes the identification information Q attached to the board B at time Tr1 while the conveyor is moving (times T11 to T12) (the recognition process is carried out).

[0034] In odd-shaped component mounting device M9, the carry-in process is carried out from time T21 to T22, the working process (component mounting work) from time T22 to T23, and the carry-out process from time T23 to T24. In odd-shaped component mounting device M9, the carry-in process starts during the carry-out process (time T11 to T12) of loader device M8 (time T11 < time T21 < time T12). In local soldering device M10, the carry-in process is carried out from time T31 to T32, the working process (local soldering work) from time T32 to T33, and the carry-out process from time T33 to T34. In local soldering device M10, the carry-in process starts during the carry-out process (time T23 to T24) of odd-shaped component mounting device M9 (time T23 < time T31 < time T24).

[0035] 5A, in unloader device M11, the carry-in process is performed from time T41 to T42. In unloader device M11, the recognition process is performed at time Tr2 while the conveyor is in operation (time T41 to T42). Production time calculation unit 34 calculates (estimates) the time when the component mounting work of odd-shaped components C1 and C2 on board B is completed from the collected work time of odd-shaped component mounting device M9 and the standard work time included in standard time data 31b.

[0036] Specifically, the production time calculation unit 34 calculates the end time T25 (T22+D11) of the component mounting work for the odd shaped component C1 by adding the standard work time D11 for the component mounting work for the odd shaped component C1, which is included in the standard time data 31b, to the time T22 when the component mounting work starts. The production time calculation unit 34 also calculates the end time T26 (T22+D11+D12) of the component mounting work for the odd shaped component C2 by adding the standard work time D12 for the component mounting work for the odd shaped component C2 to the calculated end time T25 of the component mounting work for the odd shaped component C1.

[0037] Next, an example of integrated management will be described with reference to FIG. 5B. FIG. 5B is a diagram illustrating an example of integrated management by the mounting line management device (process management device) 5. In this example, it is assumed that the management method determined on the management method setting screen 40 shown in FIG. 4 is set. That is, the loader device M8 and the unloader device M11 are set as production devices to be subject to information collection. Identification information Q attached to the board B by the recognition unit R is collected from the loader device M8 and the unloader device M11. The production time calculation unit 34 adds the standard operation time D21, which is included in the standard time data 31b and covers from the recognition process of the loader device M8 to the completion of the carry-in process of the odd-shaped component mounting device M9, to the time Tr3 at which the identification information Q is collected from the loader device M8, to calculate (estimate) the end time T51 (Tr3+D21) of the carry-in process (start time of the work process).

[0038] Similarly, the production time calculation unit 34 adds the standard work time D22 of the component mounting work to the end time T51 of the carrying-in process to calculate the end time T52 of the work process (Tr3+D21+D22) (start time of the carrying-out process). Also, the production time calculation unit 34 adds the standard work time D23 of the carrying-out process to the end time T52 of the work process to calculate the end time T53 of the carrying-out process (Tr3+D21+D22+D23).

[0039] In Figure 5B, the production time calculation unit 34 subtracts the standard working time D33 from the start of the unloading process of the local soldering device M10 to the collection of the identification information Q by the unloader device M11 from the time Tr4 when the identification information Q is collected from the unloader device M11, to calculate (estimate) the start time T63 (Tr4-D33) of the unloading process (end time of the work process).

[0040] Similarly, the production time calculation unit 34 subtracts the standard operation time D32 for the local soldering work from the start time T63 of the carry-out process to calculate the start time T62 of the work process (Tr4-D33-D32) (end time of the carry-in process). The production time calculation unit 34 also subtracts the standard operation time D31 for the carry-in process from the start time T62 of the work process to calculate the start time T61 of the carry-in process (Tr4-D33-D32-D31). In this way, even if production information is not collected from the odd-shaped component placement device M9 or the local soldering device M10, the start and end times of the production processes of the odd-shaped component placement device M9 and the local soldering device M10 can be calculated from the production information and standard operation times collected from other production devices. This enables accurate process management.

[0041] Next, another example of integrated management will be described with reference to FIG. 6. FIG. 6 is a diagram illustrating another example of integrated management by the mounting line management device (process management device) 5. In this example, only the loader device M8 is set as the production device from which information is collected. As in the example of FIG. 5B, the production times T71 to T73 of the odd-shaped component mounting device M9 are calculated by adding the standard operation times D21 to D23 to the time Tr5 at which the identification information Q was collected from the loader device M8. The production time calculation unit 34 calculates the start time T81 (Tr5+D41) of the carry-in process by adding the standard operation time D41, which is included in the standard time data 31b and is taken from the recognition process of the loader device M8 to the start of the carry-in process of the local soldering device M10, to the time Tr5 at which the identification information Q was collected from the loader device M8.

[0042] Furthermore, the production time calculation unit 34 adds the standard work time D31 for the carrying-in process to the start time T81 of the carrying-in process to calculate the end time T82 of the carrying-in process (Tr5+D41+D31) (start time of the work process). Furthermore, the production time calculation unit 34 adds the standard work time D32 for the local soldering work to the end time T82 of the carrying-in process to calculate the end time T83 of the work process (Tr5+D41+D31+D32) (start time of the carrying-out process). Furthermore, the production time calculation unit 34 adds the standard work time D33 for the carrying-out process to the end time T83 of the work process to calculate the end time T84 of the carrying-out process (Tr5+D41+D31+D32+D33).

[0043] As described above, the mounting line management device 5 of this embodiment is a process management device that manages production processes, and includes a management setting unit 32 that sets either integrated management, which manages the production processes as a single group, or individual management, which manages each production process individually, and an information collection unit 33 that collects work information from at least one of the multiple devices in the production process in the case of integrated management, or collects work information from each device in the production process in the case of individual management.This enables accurate process management to be performed on production lines with various configurations.The production time described below is calculated based on the start and end times of the work processes.

[0044] Next, a process management method (process management program) for managing a production process including a carry-in process for carrying in a workpiece (substrate B), a work process for performing work on the workpiece, and a carry-out process for carrying out the workpiece will be described with reference to the flow in Fig. 7. Fig. 7 is a flow diagram of a process management method according to an embodiment of the present disclosure. First, the management setting unit 32 uses the management method setting screen 40 (see Fig. 4) to set the management method to either integrated management, in which the production processes are managed as a group, or individual management, in which each step of the production process is managed individually (ST1: management method setting step).

[0045] In the case of integrated management (Yes in ST2), the recognition unit R recognizes the identification information Q attached to the workpiece (substrate B) in at least one of the carry-in process and the carry-out process (ST3: identification information recognition process). Next, the information collection unit 33 collects information on the workpiece (substrate B) recognized from the identification information Q (ST4: workpiece information collection process). In other words, in the case of integrated management, work information is collected in at least one of the multiple processes in the production process. Next, the production time calculation unit 34 calculates the production time of the workpiece in the production process (process start time, process end time) from the time the workpiece information was collected and the standard work time (ST5: integrated management production time calculation process). In other words, in the case of integrated management, the production time of the workpiece is calculated from the time the workpiece information was collected (see Figures 5B and 6).

[0046] 7, in the case of individual management (No in ST2), work information is collected at each step in the production process (ST6: work information collection step). Next, the production time calculation unit 34 calculates the production time of the work (board B) from the collected work information at each step and the standard work time (ST7: individual management production time calculation step). In this way, by setting the management method according to the production line, accurate process management can be performed on production lines with a variety of configurations.

[0047] Next, referring to FIG. 8, a configuration related to collecting the history of production work on assembly line L3, among the process management functions provided in component mounting system 1, will be described. FIG. 8 is a block diagram showing the process management configuration of component mounting system 1 according to an embodiment of the present disclosure. Assembly line management device 6 that manages assembly line L3 includes assembly storage unit 51, information processing unit 52, assembly communication unit 53, and wireless communication unit 6a. Assembly storage unit 51 is a storage device that stores operation information data 51a, worker information 51b, assembly history data 51c, etc. Assembly communication unit 53 transmits and receives various types of information to and from integrated management device 8, mounting line management device 3, and placement line management device 5 via communication network 7. Wireless communication unit 6a transmits and receives various types of information wirelessly to and from terminal device T and reader 10.

[0048] The operation information data 51a stores operation information (work instructions) in which production work performed on the assembly line L3 is broken down into worker operation levels and described in the order of the operations. The operation information data 51a stores, for example, hierarchical operation information for each production instruction number that identifies a production instruction, in the order of the process level for each work area (S1 to S5), the operation level for each work area (S1 to S5), and the operation level in which the work content is broken down into worker operations. The operation information data 51a also stores the estimated time required from the start to the end of each operation. The hierarchical structure of the operation information data 51a can be set as desired. The worker information 51b stores information (worker number) that identifies the worker working on the assembly line L3, the work skill level, working hours, etc.

[0049] 8, an information processing unit 52 transmits to a terminal device T arranged in each of work areas S1 to S5 operation information and worker information 51b contained in operation information data 51a necessary for production work assigned to that work area. The information processing unit 52 also associates information related to the production work for each workpiece (board B) collected from the terminal device T with identification information Q for each workpiece collected from the reader 10, and stores the associated information as assembly history data 51c in the assembly storage unit 51. The information processing unit 52 also transmits the collected assembly history data 51c to the integrated management device 8.

[0050] 8, the terminal device T includes a terminal communication unit 61, an input / display unit 62, a terminal control unit 63, a scheduled time exceedance determination unit 64, and a terminal storage unit 65. The terminal storage unit 65 is a storage device that stores work-related data 65a, terminal history 65b, and the like. The terminal communication unit 61 wirelessly transmits and receives various information to and from the assembly line management device 6. The operation information and worker information 51b contained in the operation information data 51a received by the terminal communication unit 61 are stored in the terminal storage unit 65 as work-related data 65a. The input / display unit 62 is a touch panel or the like, and has input and display functions.

[0051] The terminal control unit 63 controls the reception of information input to the input display unit 62, which will be described later, and the conversion of information included in the work-related data 65a and the input information into information to be displayed on the input display unit 62. The converted information is stored as terminal history 65b in the terminal storage unit 65. Furthermore, the terminal control unit 63 causes the input display unit 62 to display a manufacturing performance input screen, a screen for inputting the reason for exceeding the scheduled time, and the like, which will be described later, based on the work-related data 65a and the terminal history 65b.

[0052] An example of the manufacturing performance input screen 70 displayed on the input display unit 62 will now be described with reference to Fig. 9. Fig. 9 is a diagram showing an example of the manufacturing performance input screen 70 displayed on the input display unit 62 of the terminal device T. Here, an example of the manufacturing performance input screen 70 displayed on the input display unit 62 of the terminal device T arranged in the work area S3 is shown. The manufacturing performance input screen 70 displays a "worker name" display frame 70a, an information screen section 71, a first screen section 72, a second screen section 73, and a third screen section 74. The "worker name" display frame 70a displays the name of the worker (OP1) that identifies the worker who operates the terminal device T to perform the work.

[0053] Information about the work assigned to work area S3 is displayed in information screen section 71. In this example, the information screen section 71 displays the work (board B) manufacturing number (OD012), item name (B1), manufacturing instruction number (MI0001), process number (PR002) and work number (WK03) of the work assigned to work area S3, work area name (S3), planned start date (2020 / 03 / 18), and planned completion date (2020 / 03 / 20).

[0054] In FIG. 9, the first screen section 72 displays a work report button group 72a, a performance display frame 72b, and a post-setup report button group 72c. The work report button group 72a displays multiple buttons for reporting work content during production work. The setup start button is a button for reporting the start of setup work to change the item to be manufactured, and the setup end button is a button for reporting the end of setup work. Note that the buttons shown in the work report button group 72a and the post-setup report button group 72c are merely examples, and other buttons may be included. For example, a button may be included that allows the user to return to the previous state if a button operation is incorrect.

[0055] The process start button 72d is a button for reporting the start of production work. The process end button 72e is a button for reporting the end of production work. The interrupt button is a button for reporting the temporary interruption of production work, and the stop button is a button for reporting the stop of production work. The setup start button, setup end button, process start button, process end button, interrupt button, and stop button are buttons for inputting work items related to the work of machining a workpiece.

[0056] In Figure 9, the incidental work button is a button used to report the start of work not directly related to production, such as powering on equipment, maintenance, or cleaning. The lunch break button is a button used to report the start of a lunch break. The non-work button is a button used to report the start of work other than production work, such as a meeting. The indirect work button is a button used to report the start of indirect work that is not counted as man-hours for processing workpieces. The incidental work button, lunch break button, non-work button, and indirect work button are buttons used to input non-work items other than work processing workpieces. In other words, non-work items include items related to production preparation, worker breaks, and movement.

[0057] The performance display frame 72b displays the number of workpieces started, completed, and defective for the entire production number (total) and the production instruction number (current). The defect cause input frame allows the cause of the defect for the defective workpiece to be entered. The post-setup report button group 72c displays a post-setup start button for reporting the start of post-setup work for the next day's work, a post-setup end button for reporting the completion of post-setup work, and an end button for reporting the completion of the day's work.

[0058] In this way, the first screen section 72 is used to input the work items and non-work items of the worker working on the work. The work items are associated with multiple pieces of action information contained in the work-related data 65a. When a button corresponding to a work item or non-work item is operated (selected), the terminal control unit 63 accepts the information corresponding to the selected button. The terminal control unit 63 associates the accepted information and the time of acceptance with the action information contained in the work-related data 65a and stores them in the terminal history 65b.

[0059] 9, a history list display frame 73a is displayed in the second screen section 73. The history list display frame 73a displays the history of operation information entered in the first screen section 72. A simultaneous worker input frame 74a and a simultaneous worker display frame 74b are displayed in the third screen section 74. When a worker number identifying a worker is entered in the simultaneous worker input frame 74a and the add button is operated (selected), the worker entered in the simultaneous worker display frame 74b is registered as a simultaneous worker. The workers (three in this case) who report production work on this terminal device T are registered as simultaneous workers.

[0060] Concurrent workers include workers working in the same work area S3, as well as workers working in an adjacent work area S2 when a terminal device T is not located in the adjacent work area S2. In this way, information about workers working simultaneously (worker numbers of concurrent workers) is entered in the third screen section 74. When a work item or non-work item is entered, the terminal control unit 63 associates information about the workers working simultaneously with the operation information history and stores it in the terminal history 65b. This makes it possible to record in detail the work performance of workers who do not have a terminal device T or workers working together. Note that when the delete button in the concurrent worker display frame 74b is selected, that worker is deleted from the concurrent workers.

[0061] Next, an example of a manufacturing performance input screen 75 during production work will be described with reference to Fig. 10. Fig. 10 is a diagram showing an example of a manufacturing performance input screen 75 during production work displayed on a terminal device T. When a process start button 72d in the first screen section 72 on the manufacturing performance input screen 70 shown in Fig. 9 is operated, the production work starts, and the process start button displayed in the first screen section 72 changes to a next button 76a on the manufacturing performance input screen 75 shown in Fig. 10. Furthermore, operable buttons on the manufacturing performance input screen 75 shown in Fig. 10 are hatched with diagonal lines. Here, in addition to the next button 76a, an interrupt button, a stop button, a process end button 76b, an incidental work button, a lunch break button, a non-work button, and an indirect work button are displayed as operable buttons.

[0062] When a worker operates the process start button 72d on the manufacturing performance input screen 70 shown in FIG. 9, the operation instructions (operation information) for the worker stored in the work-related data 65a are displayed in the history list display frame 77a of the second screen section 77 on the manufacturing performance input screen 75 shown in FIG. 10. When the worker completes the operation and operates the Next button 76a, the terminal control unit 63 associates the completion time with the completed operation information and stores it in the terminal history 65b, and also adds the completion date and time of the operation instruction to the history list display frame 77a of the second screen section 77. The stored terminal history 65b is transmitted to the assembly line management device 6. Note that to prevent input errors, input from the Next button 76a may be disabled for a predetermined time after input from the Next button 76a.

[0063] 10, the history list display frame 77a displays a list of completed operation instructions (removing a screw, screw tightening A, screw tightening B) and the completion date and time. Furthermore, when the next button 76a is operated, the terminal control unit 63 causes the history list display frame 77a to display the next operation instruction. In the history list display frame 77a, the operation instruction (inspection) that the worker should currently perform is hatched with diagonal lines.

[0064] In this way, when a work item or non-work item is input in the first screen section 76, the terminal control unit 63 displays a history of operation information associated with the input work item or non-work item in the second screen section 77. The terminal control unit 63 also displays operation information according to the number of times the Next button 76a was operated, i.e., the number of times the work item was input, and the time when the operation was completed in chronological order as a history list.

[0065] 8, the scheduled time exceedance determination unit 64 determines whether the actual production time (actual time) from the start to the end of a work item stored in the terminal history 65b has exceeded the scheduled time stored in the work-related data 65a. If it is determined that the scheduled time has exceeded, that is, if the time from the start to the end of the input work item is longer than the scheduled time, the terminal control unit 63 causes the input display unit 62 to display a scheduled time exceedance reason input screen for prompting the user to enter the reason for the scheduled time exceedance.

[0066] An example of the scheduled time exceeding reason input screen 78 will now be described with reference to Fig. 11. Fig. 11 is a diagram showing an example of the scheduled time exceeding reason input screen 78 displayed on the terminal device T. The scheduled time exceeding reason input screen 78 displays an information screen section 79 and an input screen section 80. The information screen section 79 displays information about the work (action) that exceeded the scheduled time. In this example, the information screen section 79 displays the item name (B1), process number (PR002), work number (WK03), work execution date and time (2020 / 03 / 18 09:12 to 2020 / 03 / 18 09:14), the scheduled time of the work (1 minute), and the actual time (2 minutes).

[0067] The input screen section 80 displays a cause input frame 81, a comment input frame 82, and a reflect button 83. The worker selects the cause of the exceeded scheduled time and a comment from the drop-down lists displayed in the cause input frame 81 and comment input frame 82. In this example, "Procedure unknown" is selected as the cause, and "New employee, long time no see working" is selected as the comment. When the reflect button 83 is operated, the cause of the exceedance and the comment are stored in the terminal history 65b in association with the work (action) that exceeded the scheduled time, and the screen transitions to a manufacturing performance input screen that displays the details of the next work.

[0068] As described above, the terminal device T includes an input / display unit 62 and a terminal control unit 63 that receives information input to the input / display unit 62 and controls conversion of the input information into information to be displayed on the input / display unit 62. The input / display unit 62 includes first screen sections 72, 76 in which the work items and non-work items of the worker working on the workpiece (board B) are input, and second screen sections 73, 77 in which the history of operation information associated with the work items or non-work items is displayed. This allows the work performance of the worker to be recorded in detail.

[0069] FIG. 12 is a flow diagram of a display method according to an embodiment of the present disclosure. Next, along with the flow of FIG. 12 and with reference to FIGS. 9 to 11, a display method (display program) in a terminal device T that includes an input / display unit 62, accepts information input to the input / display unit 62, converts the information, and displays it on the input / display unit 62 will be described. First, the terminal control unit 63 causes the input / display unit 62 to display a manufacturing performance input screen 70 (ST11: manufacturing performance input screen display step) (see FIG. 9). When the process start button 72d in the first screen section 72 on the manufacturing performance input screen 70 shown in FIG. 9 is operated (Yes in ST12), the terminal control unit 63 causes the history list display frame 77a in the second screen section 77 on the manufacturing performance input screen 75 shown in FIG. 10 to display information on the next operation to be performed by the worker (ST13: operation information display step) (see FIG. 10).

[0070] Next, the terminal control unit 63 accepts input (button operation) of the work item or non-work item displayed in the first screen section 76 (ST14: item input step). If the end of the process is input (the end of process button 76b is operated) (Yes in ST15), the process input ends. If something other than a work process is input (any button other than the next button 76a is operated) (No in ST16), the terminal control unit 63 associates the input item with the time of input and stores them in the terminal storage unit 65, and returns to the item input step (ST14).

[0071] 12, when a work step is input (the Next button 76a is operated) (Yes in ST16), the terminal control unit 63 adds the completion date and time of the action to the history list display frame 77a, associates the completion date and time with the action information, and stores them in the terminal history 65b (ST17: completion date and time adding step). That is, in response to the input of the work item (ST15 to ST16), the terminal control unit 63 displays the time when the action was completed in the history of the action information (ST17).

[0072] Next, the scheduled time exceeding determination unit 64 calculates the actual work time (actual time) from the start to the end of the input work item (ST18: work time calculation step). If the scheduled time exceeding determination unit 64 determines that the actual time is within the scheduled time (No in ST19), the process returns to the operation information display step (ST13), and the operation information to be performed next by the worker is displayed in the history list display frame 77a. If the scheduled time exceeding determination unit 64 determines that the actual time exceeds the scheduled time (Yes in ST19), the terminal control unit 63 causes the input display unit 62 to display a scheduled time exceeding reason input screen 78, which prompts the user to input the reason for the scheduled time exceeding (ST20: scheduled time exceeding reason input screen display step) (see FIG. 11).

[0073] 12, when the reason for exceeding the scheduled time is entered on the scheduled time exceeding reason input screen 78, the process returns to the operation information display step (ST13), and the operation information to be performed next by the worker is displayed in the history list display frame 77a. That is, operation information according to the number of times the work item is entered (the number of times ST16 was Yes) is displayed as a history list in the history list display frame 77a (ST13). In this way, the display method of the present disclosure makes it possible to record the work performance of the worker in detail.

[0074] In the above description, the mounting line management device 3 collects history information about the production equipment on the component mounting line L1, the mounting line management device 5 collects history information about the production equipment on the component mounting line L2, and the assembly line management device 6 collects history information about the assembly line L3. However, the component mounting system 1 is not limited to this configuration. For example, the integrated management device 8 may directly collect history information about the production equipment on the component mounting line L1, the production equipment on the component mounting line L2, and the assembly line L3. Furthermore, the integrated management device 8, the mounting line management device 3, the mounting line management device 5, and the assembly line management device 6 do not have to be configured as a single computer, but may be configured as multiple devices. For example, all or part of the storage device and internal processing unit may be provided in the cloud via a server.

[0075] In the above, the process management method (process management program) for managing a production process including a carry-in process for carrying in the workpiece (substrate B), a work process for performing operations on the workpiece, and an unloading process for unloading the workpiece is set as either integrated management, in which the production processes are managed as a single group, or individual management, in which each process in the production process is managed individually (ST1: management method setting process). However, if the configuration of the production line is fixed and the management of each process does not change, the management method setting process does not need to be included. Instead, a management method determination process is included that determines whether integrated management, in which the production processes are managed as a single group, or individual management, in which each process in the production process is managed individually, is used.

[0076] In the above, the production time of a workpiece in a production process is calculated from the process start time and process end time, but other calculation methods may be used. For example, the measured time can be calculated as the production time by starting measurement from the process start time and ending measurement at the process end time. In the above, the production time (production completion time) is used, but this timing can be changed as appropriate within the range of the production time depending on the workpiece.

[0077] In the above, the process control device (mounting line control device 5) and terminal device T are described as examples of production lines, such as a component mounting line L1 that mounts components P on a board B, a component mounting line L2 that mounts odd-shaped components C on a board B, and an assembly line L3 where workers perform production work on the board B, but the production line is not limited to these. For example, the production line may be a semiconductor production line that manufactures semiconductors, an assembly production line that assembles workpieces (products) such as electrical machinery and equipment, general machinery and equipment, or a food processing line that produces processed food products.

[0078] In the above-described embodiments, each component may be configured with dedicated hardware, or may be realized by executing a software program suitable for each component. Each component may be realized by a program execution unit such as a CPU (Central Processing Unit) or a processor reading and executing a software program recorded on a recording medium such as a hard disk or semiconductor memory.
