Abstract
Description
[Technical Field]
[0001] The present disclosure generally relates to a management method and a management system, and more particularly to a management method and a management system for managing a component mounting apparatus equipped with a component supplying device that supplies components. [Background technology]
[0002] Patent Document 1 describes a management device that manages multiple production lines. On each production line, a printer, an inspection machine, a component mounter, and a reflow furnace are arranged in the board transport direction. The component mounter is equipped with multiple feeders. Each feeder is equipped with a component supply reel around which a component supply tape is wound.
[0003] When a mounter runs out of components on a component supply tape, it is necessary to replenish the feeder with a new component supply tape. At this time, the operator must perform a splicing operation to join the end of the component supply tape that has run out with the beginning of the new component supply tape. However, a mistake in this splicing operation can cause an error when switching component supply tapes.
[0004] The management device described in Patent Document 1 is equipped with a display, and displays on the display the stop time of the component mounter due to each of a plurality of errors that occur in the component mounter. [Prior art documents] [Patent documents]

[0006] The management device (management system) described in Patent Document 1 has the problem that it only displays the occurrence status of errors that have occurred in the component mounter (component mounter), but does not allow for understanding of the work efficiency resulting from the splicing work.
[0007] An object of the present disclosure is to provide a management method and a management system that are capable of grasping the work efficiency resulting from splicing work. [Means for solving the problem]
[0008] A management method according to one aspect of the present disclosure is a method for managing a component mounting apparatus including a component supply device to which multiple component tapes, including a first component tape and a second component tape, are sequentially attached and which supplies multiple components held on each of the multiple component tapes. The management method includes an acquisition step, a calculation step, and a display control step. The acquisition step acquires shift information including information about a time period during which a worker performing a splicing operation is engaged. The splicing operation is an operation of splicing a starting end of a second component tape to a finishing end of a first component tape that is attached to the component supply device earlier than the second component tape. The calculation step calculates an index indicating a skill level of the splicing operation based on production results. The production results indicate at least one of errors that occurred during a predetermined period after the component supply device switched from the first component tape to the second component tape and events that reduce the availability of the component mounting apparatus. The display control step displays related information related to the index for each of multiple time periods on a display device based on the shift information.

[0012] The management methods and management systems according to the first and second embodiments will be described below with reference to the drawings. The drawings referred to in the following first and second embodiments are schematic diagrams, and the sizes and thicknesses of the components in the drawings do not necessarily reflect the actual dimensions, and the size ratios and thickness ratios between the components do not necessarily reflect the actual dimensional ratios.
[0013] (Embodiment 1) (1) Overview First, an overview of a management method and a management system 2 according to a first embodiment will be described with reference to FIGS.
[0014] The management method according to the first embodiment is a management method for managing the component mounting apparatus 1. As shown in Fig. 2, the component mounting apparatus 1 includes a component supply device 12. The component supply device 12 is a device to which multiple component tapes, including a first component tape and a second component tape, are sequentially attached, and which supplies multiple components held by each of the multiple component tapes.
[0015] As shown in FIG. 3, the management method according to the first embodiment includes an acquisition step ST1, calculation steps ST3, ST5, and ST7, and a display control step ST9. In the acquisition step ST1, shift information (worker information In1, described below) including information about the time period during which the worker performing the splicing operation is engaged (shift number information In12, described below) is acquired. The splicing operation involves splicing the beginning end of a second component tape to the end end of a first component tape that was attached to the component supply device 12 before the second component tape. In the calculation steps ST3, ST5, and ST7, indicators indicating the skill level of the splicing operation (the pickup error rate and replacement success rate, described below) are calculated based on production results. The production results indicate at least one of errors that occurred during a predetermined period after the component supply device 12 switched from the first component tape to the second component tape and events that reduce the availability of the component mounting device 1. In the display control step ST9, the display device 5 is caused to display related information In5 (see FIG. 5) relating to the index for each of the plurality of time periods based on the shift information described above.
[0016] In the management method according to the first embodiment, in the display control step ST9, the related information In5 for each time period is displayed on the display device 5 (see FIG. 5). Therefore, by looking at the related information In5 displayed on the display device 5, the worker can grasp the work efficiency resulting from the splicing work for each time period.
[0017] 1 and 2. In other words, the management system 2 is one aspect for realizing the above-described management method. That is, the management system 2 according to the first embodiment is a management device (hereinafter also referred to as "management device 2") for managing the component mounting apparatus 1. As shown in FIG. 2, the management system 2 includes an acquisition unit 211, a calculation unit 212, and a display control unit 213. The acquisition unit 211 acquires the above-described shift information in an acquisition step ST1. The calculation unit 212 calculates the above-described indexes based on the above-described production results in calculation steps ST3, ST5, and ST7. The display control unit 213 displays related information In5 on the display device 5 based on the above-described shift information in a display control step ST9 (see FIG. 5).
[0018] In the management system 2 according to the first embodiment, the display control unit 213 displays the related information In5 for each time period on the display device 5 (see FIG. 5). Therefore, a worker who views the related information In5 displayed on the display device 5 can grasp the work efficiency resulting from the splicing work for each time period.
[0019] The management system 2 mainly comprises a computer system having one or more processors and one or more memories. In other words, the management method according to the first embodiment is used on the computer system (management system 2). In other words, the management method can also be realized as a program.
[0020] (2) Details Next, each component of the management system 2 according to the first embodiment will be described with reference to Fig. 1 and Fig. 2. As described above, the management system 2 according to the first embodiment is the management device 2 for managing the component mounting device 1. The management device 2, together with the component mounting device 1, constitutes the production line management system 10.
[0021] 1, the production line management system 10 includes a first production line L1, a second production line L2, and multiple (two in the illustrated example) management devices 2A and 2B. The management device 2A corresponds to the first production line L1 and manages the first production line L1. The management device 2B corresponds to the second production line L2 and manages the second production line L2.
[0022] Since the first production line L1 and the second production line L2 have the same configuration, only the first production line L1 will be described below. Also, since the management device 2A and the management device 2B have the same configuration, only the management device 2A will be described below.
[0023] (2.1) Production Line As shown in FIG. 1, the first production line L1 includes a solder printing device M1, multiple component mounting devices M2 and M3 (two in the illustrated example), and a reflow device M4. In the first production line L1, the solder printing device M1, the multiple component mounting devices M2 and M3, and the reflow device M4 are connected in series in this order. Although not shown, upstream of the solder printing device M1 are a board supply device that supplies boards and a board transfer device that transfers boards supplied from the board supply device to the solder printing device M1. Similarly, although not shown, downstream of the reflow device M4 is a board recovery device (described below) that recovers mounted boards. The board supply device, board transfer device, solder printing device M1, the multiple component mounting devices M2 and M3, the reflow device M4, and the board recovery device are connected to a management device 2A via a communication network N1.
[0024] The solder printing device M1, multiple component mounting devices M2 and M3, and reflow device M4 perform component mounting work to mount components on boards transported along the first production line L1. That is, boards supplied by a board supply device are carried into the solder printing device M1 via a board delivery device. The solder printing device M1 performs solder printing work to screen-print solder for joining components on the carried-in boards.
[0025] The solder-printed boards are sequentially handed over to multiple component mounting devices M2 and M3. The multiple component mounting devices M2 and M3 perform component mounting work, mounting components onto the solder-printed boards. The boards after component mounting are carried into reflow device M4 and heated according to a predetermined heating process. This melts and solidifies the solder printed on the heated board for joining components. The components are then solder-bonded to the board, producing a mounted board, which is a finished product with components mounted on the board. The produced mounted board is collected by a board collection device.
[0026] (2.2) Component mounting equipment As described above, each of the component mounting devices M2 and M3 is a component mounting device (hereinafter also referred to as a "component mounting device 1") that performs component mounting work to mount components on a board. As shown in Fig. 2, the component mounting device 1 includes a mounting head 11, a component supply device 12, a board transport device 13, a control device 14, and a drive device 15.
[0027] (2.2.1) Drive unit The driving device 15 is a device for moving the mounting head 11 in the horizontal direction. The driving device 15 includes a first linear motor and a second linear motor. The driving device 15 moves the mounting head 11 linearly along a first direction in a predetermined horizontal plane by using a driving force generated by the first linear motor. The driving device 15 also moves the mounting head 11 linearly along a second direction in the predetermined horizontal plane by using a driving force generated by the second linear motor. The first direction and the second direction are directions that intersect (for example, are perpendicular to) each other in the predetermined horizontal plane.
[0028] (2.2.2) Mounting head The mounting head 11 is a device for mounting components supplied from the component supply device 12 onto a board. The mounting head 11 has a holding unit and an actuator.
[0029] The holding unit is, for example, a suction nozzle. The holding unit is capable of switching between a state in which it picks up a component and a state in which it releases the suction of the component. Note that the holding unit is not limited to a suction nozzle, and may be configured to hold a component by grasping (picking) it like a robot hand, for example.
[0030] The actuator moves the holding part linearly in the vertical direction. The actuator also rotates the holding part in a rotational direction about an axis along the vertical direction. The actuator includes a linear motor and a rotary motor. The actuator moves the holding part linearly in the vertical direction by a driving force generated by the linear motor. The actuator also rotates the holding part in the rotational direction by a driving force generated by the rotary motor.
[0031] (2.2.3) Parts supply device The component supply device 12 is a device that supplies components to the mounting head 11. The component supply device 12 has, for example, a tape feeder. Multiple component tapes (carrier tapes) are sequentially attached to the tape feeder. Each of the multiple component tapes holds multiple components. The component supply device 12 moves the components to the component supply port by feeding the component tapes in one direction using the tape feeder. In this embodiment, the multiple component tapes include a first component tape and a second component tape. The first component tape is attached to the tape feeder before the second component tape. That is, the component supply device 12 sequentially attaches multiple component tapes, including the first component tape and the second component tape, and supplies the multiple components held by each of the multiple component tapes.
[0032] (2.2.4) Substrate transport device The board transport device 13 is a device that transports a board received from an upstream device to a downstream device. For example, if the component mounting device 1 is the component mounting device M2, the board transport device 13 transports the board received from the solder printing device M1 to the component mounting device M3. Also, if the component mounting device 1 is the component mounting device M3, the board transport device 13 transports the board received from the component mounting device M2 to the reflow device M4. The board transport device 13 has a pair of conveyor mechanisms. The board transport device 13 transports the board in one direction (the direction in which the devices are lined up) using the pair of conveyor mechanisms.
[0033] (2.2.5) Control device The control device 14 controls each unit of the component mounting apparatus 1. The control device 14 can be realized, for example, by a computer system having one or more processors and one or more memories. That is, the control device 14 functions by having one or more processors execute a program recorded in one or more memories of the computer system. Here, the program is pre-recorded in the memory of the control device 14, but it may also be provided via a telecommunications line such as the Internet, or may be recorded on a non-transitory recording medium such as a memory card and provided. The control device 14 includes, for example, an FPGA (Field-Programmable Gate Array).
[0034] The control device 14 is electrically connected to, for example, each of the mounting head 11, component supply device 12, board transport device 13, and drive device 15. The control device 14 outputs control signals to the mounting head 11 and drive device 15, and controls the mounting head 11 and drive device 15 so that components are mounted at predetermined positions on the board. The control device 14 also outputs control signals to the component supply device 12, and controls the component supply device 12 so that components are positioned at the component supply port. The control device 14 also outputs control signals to the board transport device 13, and controls the board transport device 13 so that the board is positioned in the mounting space.
[0035] (2.3) Management device The management device 2A is, for example, a personal computer. The management device 2A can be realized, for example, by a computer system having one or more processors and one or more memories. That is, the management device 2A functions as the management device 2A when one or more processors execute a program recorded in one or more memories of the computer system. Here, the program is pre-recorded in the memory of the computer system, but it may also be provided via a telecommunications line such as the Internet, or may be recorded on a non-transitory recording medium such as a memory card and provided.
[0036] As shown in FIG. 2, the management device 2A includes a control unit 21 and an interface 22.
[0037] (2.3.1) Control Unit The control unit 21 performs overall control of the management device 2A. The control unit 21 controls the interface 22 to transmit and receive data between the component mounting device 1, the storage device 3, the barcode reader 4, and the display device 5. The control unit 21 includes an acquisition unit 211, a calculation unit 212, and a display control unit 213.
[0038] The acquisition unit 211 acquires worker information In1 (see FIG. 2). The worker information In1 includes worker ID information In11 and shift number information In12. Table 1 shows an example of the worker information In1.
[0039] [Table 1]
[0040] On the first production line L1, the worker ID information In11 includes any one of the codes "A" to "I." Also, on the first production line L1, the shift number information In12 includes any one of the numbers "1" to "3." Of the nine workers working on the first production line L1, three workers assigned worker IDs "A" to "C" are assigned to the "shift 1" time period. Of the nine workers working on the first production line L1, three workers assigned worker IDs "D" to "F" are assigned to the "shift 2" time period. Of the nine workers working on the first production line L1, three workers assigned worker IDs "G" to "I" are assigned to the "shift 3" time period.
[0041] On the second production line L2, the worker ID information In11 includes any one of the codes "AA" to "II." Also, on the second production line L2, the shift number information In12 includes any one of the numbers "1" to "3." Of the nine workers working on the second production line L2, three workers assigned worker IDs "AA" to "CC" are assigned to the "shift 1" time period. Of the nine workers working on the second production line L2, three workers assigned worker IDs "DD" to "FF" are assigned to the "shift 2" time period. Of the nine workers working on the second production line L2, three workers assigned worker IDs "GG" to "II" are assigned to the "shift 3" time period.
[0042] In this embodiment, as an example, "Shift 1" is the time period from 6:00 AM to 2:00 PM, "Shift 2" is the time period from 2:00 PM to 10:00 PM, and "Shift 3" is the time period from 10:00 PM to 6:00 AM.
[0043] Here, the above-mentioned splicing work is required in each of "Shift 1," "Shift 2," and "Shift 3." Furthermore, the three workers working in "Shift 1," the three workers working in "Shift 2," and the three workers working in "Shift 3" are different from one another. Therefore, the number of occurrences of errors and / or specific events caused by the splicing work in each shift differs from one another. For example, in a shift in which workers with a low level of splicing skill are employed, the number of occurrences of errors and / or specific events caused by the splicing work tends to be higher than in other shifts.
[0044] Errors caused by the splicing operation include, for example, a component pickup error by the suction nozzle of the mounting head 11, or a recognition error of the component picked up by the suction nozzle. Pickup errors may be detected, for example, based on the amount of air supplied to the suction nozzle, or based on the image capture results of a recognition camera used to recognize the component picked up by the suction nozzle, or both. When detecting pickup errors based on the amount of air, the amount of air is greater when no component is picked up by the suction nozzle than when a component is picked up by the suction nozzle. Therefore, a pickup error can be detected when the amount of air exceeds a threshold value (for example, the amount of air when a component is picked up by the suction nozzle).
[0045] Furthermore, specific events caused by splicing work are events that reduce the availability of the component mounting apparatus 1, such as the events associated with the above-mentioned component tape replacement. More specifically, the specific events are events such as performing pickup position teaching to align the positional relationship between the components on the second component tape and the pickup nozzle, not detecting components at the component supply port, the cover tape of the second component tape breaking midway, or not feeding the second component tape.
[0046] In this embodiment, the shift number information In12 corresponds to information about the time period during which the worker performing the splicing operation is employed, and the worker information In1 corresponds to shift information including information about the time period. That is, the acquisition unit 211 acquires shift information including information about the time period during which the worker performing the splicing operation of joining the starting end of a second component tape to the ending end of a first component tape that was attached to the component supply device 12 earlier than the second component tape is employed.
[0047] The calculation unit 212 calculates an index indicating the skill level of the splicing operation based on the production results. The production results include information regarding at least one of the above-mentioned errors and the above-mentioned specific events that occurred during a predetermined period after the component supply device 12 switched from the first component tape to the second component tape. More specifically, the production results are at least one of the number of component pickup errors by the suction nozzles that occurred during the predetermined period and the number of occurrences of the above-mentioned specific events. The index is a value indicating the skill level of the splicing operation, and is the component pickup error rate by the suction nozzles or the success rate of component tape replacement. That is, the calculation unit 212 calculates the index indicating the skill level of the splicing operation based on the production results that indicate the number of occurrences of at least one of the following: errors that occurred during a predetermined period after the component supply device 12 switched from the first component tape to the second component tape and the number of occurrences of events (specific events) that reduce the availability of the component mounting device 1.
[0048] The display control unit 213 is electrically connected to the display device 5 via the interface 22. The display control unit 213 controls the display device 5. The display control unit 213 controls the display device 5 to display related information In5 (see FIG. 5 ). At this time, the display control unit 213 causes the display device 5 to display related information In5 for each time period ("Shift 1," "Shift 2," "Shift 3") based on the shift information (worker information In1). The related information In5 is information related to indicators for each of a plurality of time periods. In other words, the display control unit 213 causes the display device 5 to display related information In5 related to indicators for each of a plurality of time periods based on the shift information.
[0049] (2.3.2) Interface The interface 22 electrically connects the management device 2A with each of the component mounting device 1, the storage device 3, the barcode reader 4, and the display device 5. By electrically connecting the management device 2A with the component mounting device 1, the interface 22 acquires the above-mentioned production results from the component mounting device 1. Furthermore, by electrically connecting the management device 2A with the storage device 3, the interface 22 stores the worker information In1, the first work information In2, the second work information In3, and the result information In4 in the storage device 3 and reads them out from the storage device 3.
[0050] Furthermore, the interface 22 electrically connects the management device 2A and the barcode reader 4, thereby acquiring the worker ID information In11 read by the barcode reader 4 from the barcode reader 4. Furthermore, the interface 22 electrically connects the management device 2A and the display device 5, thereby causing the display device 5 to display the related information In5.
[0051] (2.4) Storage device The storage device 3 includes, for example, semiconductor memory such as ROM (Read Only Memory), RAM (Random Access Memory), or EEPROM (Electrically Erasable Programmable Read Only Memory). Note that the storage device 3 is not limited to semiconductor memory and may be a hard disk drive or the like. The storage device 3 stores, for example, worker information In1, first work information In2, second work information In3, and performance information In4.
[0052] The worker information In1 is information about the worker, and includes shift number information In12, which is information about the time period in which the worker is employed. In this embodiment, as described above, the shift number information In12 includes any one of "Shift 1," "Shift 2," and "Shift 3." The worker information In1 also includes worker ID information In11, which is information about the ID of the worker. In this embodiment, as described above, the worker ID information In11 includes any one of the codes "A" to "I" or "AA" to "II."
[0053] The first work information In2 includes, for example, information relating to component pickup errors by the suction nozzle. More specifically, the first work information In2 includes the pickup error rate that occurs during a predetermined period of time after switching from the first component tape to the second component tape. The predetermined period is, for example, the period from switching from the first component tape to the second component tape until 50 to 100 components are sent to the component supply outlet of the component supply device 12. As an example, if the predetermined period is the period until 100 components are sent to the component supply outlet of the component supply device 12, the pickup error rate is the percentage of the number of components that have failed to be picked up out of the 100 components.
[0054] The second work information In3 includes, for example, information related to component tape replacement. More specifically, the second work information In3 includes the component tape replacement success rate. The replacement success rate is calculated based on the percentage of component tape replacement errors relative to the total number of component tape replacements. For example, if the total number of component tape replacements is 200 and the number of component tape replacement errors is 5, the replacement success rate is (1-5 / 200) x 100 = 97.5%. Here, component tape replacement errors occur due to the specific events described above, which require the tape feeder to be detached. Therefore, the number of tape feeder attachments and detachments can be considered the number of component tape replacement errors.
[0055] The performance information In4 is information in which a worker ID is linked to the work performance of the worker to whom the worker ID is assigned. That is, the storage device 3 stores the work performance for each worker.
[0056] (2.5) Barcode Reader As described above, the barcode reader 4 is electrically connected to the management device 2A via the interface 22. The barcode reader 4 is a device that reads one-dimensional codes (barcodes) or two-dimensional codes (e.g., QR Code (registered trademark)). In this embodiment, the barcode reader 4 acquires worker ID information In11 by, for example, reading a one-dimensional code or a two-dimensional code displayed on an identification card (e.g., an employee ID card) held by a worker. The barcode reader 4 then transmits the acquired worker ID information In11 to the management device 2A via the interface 22.
[0057] (2.6)Display device As described above, the display device 5 is electrically connected to the management device 2A via the interface 22. The display device 5 is, for example, a liquid crystal display. The display device 5 displays the related information In5 acquired from the management device 2A via the interface 22 (see FIG. 5).
[0058] (3) Management method Next, a management method according to the first embodiment will be described with reference to FIGS.
[0059] The management method according to the first embodiment is a management method for managing a component mounting apparatus 1. The component mounting apparatus 1 includes a component supply device 12. A plurality of component tapes, including a first component tape and a second component tape, are sequentially attached to the component supply device 12, and the component supply device 12 supplies a plurality of components held by each of the plurality of component tapes.
[0060] The management method according to the first embodiment includes, for example, an acquisition step ST1, calculation steps ST3, ST5, and ST7, and a display control step ST9, as shown in FIG. 3. In the acquisition step ST1, shift information (worker information In1) including information about the time period during which the worker performing the splicing operation is engaged (shift number information In12) is acquired. The splicing operation involves splicing the beginning end of a second component tape to the end end of a first component tape that was attached to the component supply device 12 before the second component tape. In the calculation steps ST3, ST5, and ST7, an index indicating the skill level of the splicing operation (pickup error rate or replacement success rate) is calculated based on production results. The production results indicate at least one of errors that occurred during a predetermined period after the component supply device 12 switched from the first component tape to the second component tape and events that reduce the availability of the component mounting device 1. In the display control step ST9, related information In5 relating to the index for each of a plurality of time periods is displayed on the display device 5 based on the shift information (worker information In1) (see FIG. 5).
[0061] In the management method according to the first embodiment, in the display control step ST9, the related information In5 for each time period is displayed on the display device 5. Therefore, a worker who views the related information In5 displayed on the display device 5 can grasp the work efficiency resulting from the splicing work for each time period.
[0062] 3 and 4 are flowcharts showing a management method executed by the management device 2 according to embodiment 1. Note that the flowcharts shown in Fig. 3 and 4 are merely examples, and the order of processes may be changed as appropriate, and processes may be added or deleted as appropriate.
[0063] (3.1) Example 1 First, a first operational example of the management device 2 according to the first embodiment will be described with reference to Fig. 3. In the first operational example, a case where there is one worker in each shift will be described as an example.
[0064] The management device 2 executes an acquisition step ST1. In the acquisition step ST1, the acquisition unit 211 of the management device 2 acquires the worker ID information In11 of the target worker (hereinafter referred to as the "target worker") from the barcode reader 4.
[0065] Next, the management device 2 executes a determination step ST2. In the determination step ST2, the control unit 21 of the management device 2 reads out the worker information In1 including the worker ID information In11 acquired by the acquisition unit 211 from the storage device 3, and determines the shift of the target worker based on the shift number information In12 included in the read worker information In1.
[0066] Thereafter, the management device 2 executes one of calculation steps ST3, ST5, and ST7. If the target worker's shift is "shift 1" (determination step ST2: shift 1), the calculation unit 212 of the management device 2 executes a first calculation process in calculation step ST3. The first calculation process is a process of calculating the pickup error rate of the target worker in shift 1. Then, the control unit 21 executes a first storage process in storage step ST4. The first storage process is a process of storing the pickup error rate of the target worker in shift 1 calculated by the calculation unit 212 in the storage device 3 as first work information In2.
[0067] Furthermore, when the target worker's shift is "shift 2" (determination step ST2: shift 2), the calculation unit 212 executes a second calculation process in calculation step ST5. The second calculation process is a process for calculating the pickup error rate of the target worker in shift 2. Then, the control unit 21 executes a second storage process in storage step ST6. The second storage process is a process for storing the pickup error rate of the target worker in shift 2 calculated by the calculation unit 212 in the storage device 3 as first work information In2.
[0068] Furthermore, when the target worker's shift is "shift 3" (determination step ST2: shift 3), the calculation unit 212 executes a third calculation process in calculation step ST7. The third calculation process is a process for calculating the pickup error rate of the target worker in shift 3. Then, the control unit 21 executes a third storage process in storage step ST8. The third storage process is a process for storing the pickup error rate of the target worker in shift 3 calculated by the calculation unit 212 in the storage device 3 as first work information In2.
[0069] In the management method according to the first embodiment, steps ST1 to ST8 are executed for all of "Shift 1," "Shift 2," and "Shift 3."
[0070] Finally, the management device 2 executes a display control step ST9. The display control unit 213 of the management device 2 executes a display control process in the display control step ST9. The display control process is a process of controlling the display device 5 so that the display device 5 displays the related information In5.
[0071] Here, in the production line management system 10 according to the first embodiment, two production lines (first production line L1 and second production line L2) are provided, and therefore, as will be explained in the display example 1 described later, indicators for each time period are displayed on the display device 5 for each production line.
[0072] (3.2) Example 2 Next, a second operational example of the management device 2 according to the first embodiment will be described with reference to Fig. 4. In the second operational example, a case where there are three workers (workers A to C) will be described as an example.
[0073] The management device 2 executes an acquisition step ST11. In the acquisition step ST11, the acquisition unit 211 of the management device 2 acquires the worker ID information In11 of the target worker (hereinafter referred to as the "target worker") from the barcode reader 4.
[0074] Next, the management device 2 executes a determination step ST12. In the determination step ST12, the control unit 21 of the management device 2 determines whether the target worker is "Worker A," "Worker B," or "Worker C" based on the worker ID information In11.
[0075] Thereafter, the management device 2 executes one of calculation steps ST13, ST15, and ST17. When the target worker is "worker A" (determination step ST12: worker A), the calculation unit 212 of the management device 2 executes a fourth calculation process in calculation step ST13. The fourth calculation process is a process of calculating the pickup error rate of worker A. Then, the control unit 21 executes a fourth storage process in storage step ST14. The fourth storage process is a process of storing the pickup error rate of worker A calculated by the calculation unit 212 in the storage device 3 as first work information In2.
[0076] Furthermore, when the target worker is "worker B" (determination step ST12: worker B), the calculation unit 212 executes a fifth calculation process in calculation step ST15. The fifth calculation process is a process of calculating the pickup error rate of worker B. Then, the control unit 21 executes a fifth storage process in storage step ST16. The fifth storage process is a process of storing the pickup error rate of worker B calculated by the calculation unit 212 in the storage device 3 as first work information In2.
[0077] Furthermore, when the target worker is "worker C" (determination step ST12: worker C), the calculation unit 212 executes a sixth calculation process in a calculation step ST17. The sixth calculation process is a process of calculating the pickup error rate of worker C. Then, the control unit 21 executes a sixth storage process in a storage step ST18. The sixth storage process is a process of storing the pickup error rate of worker C calculated by the calculation unit 212 in the storage device 3 as first work information In2.
[0078] In the management method according to the first embodiment, steps ST11 to ST18 are executed for all of the workers A to C.
[0079] Finally, the management device 2 executes a display control step ST19. The display control unit 213 of the management device 2 executes a display control process in the display control step ST19. The display control process is a process of controlling the display device 5 so that the display device 5 displays the related information In5.
[0080] Incidentally, when there are multiple workers in each shift in Operation Example 1, it is preferable to perform steps ST11 to ST18 in Operation Example 2 in advance. In this case, the calculation unit 212 of the management device 2 can calculate an index for each shift by adding up the indexes (pickup error rates) of the multiple workers in each shift. In this case, the display control step ST9 in Operation Example 1 may or may not be omitted.
[0081] (4) Display example Next, examples of display on the display device 5 by the management device 2 according to the first embodiment will be described with reference to FIGS.
[0082] (4.1) Display example 1 First, a display example 1 of the display device 5 will be described with reference to FIG.
[0083] In display example 1, the display device 5 displays the changes in indices for each shift as related information In5. More specifically, for the first production line L1, the indices for "shift 1" and "shift 3" have improved (increased), but the indices for "shift 2" have not changed. Note that in display example 1, the changes in indices for the second production line L2 are not shown.
[0084] According to display example 1, it is possible to inform each worker of the changes in indicators for each shift, and as a result, each worker can grasp the work efficiency resulting from the splicing work for each shift.
[0085] As shown in FIG. 5, when multiple time periods ("Shift 1," "Shift 2," and "Shift 3") are displayed on the display device 5, for example, by selecting one of the time periods, the display device 5 may display a message indicating that work training on splicing work will be provided to workers who performed splicing work during that time period. That is, in the display control step ST9, the display device 5 may display a message indicating that work training on splicing work will be provided to workers who performed splicing work during a specific time period selected from the multiple time periods. Furthermore, it is preferable that the specific time period is the time period with the lowest index among the multiple time periods. This makes it possible to notify the worker on the shift with the lowest index that work training will be provided.
[0086] (4.2) Display example 2 Next, a second display example of the display device 5 will be described with reference to FIG.
[0087] In display example 2, the display device 5 displays the indices for "Shift 1" on a certain date for each worker as related information In5. More specifically, on the first production line L1, the indices for worker A have improved (increased), the indices for worker B have not changed, and the indices for worker C have worsened (decreased). On the second production line L2, the indices for workers AA, BB, and CC have not changed.
[0088] According to display example 2, it is possible to inform each worker of changes in indicators for each worker, and as a result, each worker can understand the work efficiency resulting from the splicing work for each worker.
[0089] Meanwhile, as shown in display example 2, when multiple workers A to C are working in "shift 1" on the first production line L1, the calculation unit 212 of the management device 2 calculates an index for "shift 1" for each of the multiple workers A to C in calculation steps ST13, ST15, and ST17. That is, in the management method according to the first embodiment, on one production line (e.g., the first production line L1) equipped with one or more component mounting apparatuses 1, multiple workers A to C are working in one time period (e.g., "shift 1") among multiple time periods ("shift 1," "shift 2," and "shift 3"). Then, in calculation steps ST13, ST15, and ST17, an index for one time period is calculated for each of the multiple workers A to C.
[0090] (4.3) Display example 3 Next, a display example 3 of the display device 5 will be described with reference to FIG.
[0091] In display example 3, the display device 5 displays the first work information In2 for the first production line L1 as the related information In5. More specifically, the display device 5 displays, as the related information In5, indicators for multiple (three in the illustrated example) workers A to C in "shift 1" of the first production line L1. The indicators are the pickup error rates for each of the multiple workers A to C. That is, in display example 3, in display control step ST19, the display device 5 is caused to display the related information In5 for one time period ("shift 1") for each of the multiple workers A to C.
[0092] According to display example 3, it is possible to inform each worker of the indicators for each worker, and as a result, each worker can understand the work efficiency resulting from the splicing work for each worker. In this way, the related information In5 may not only be information related to the indicator, but also the indicator itself.
[0093] (5) Effects In the management method according to the first embodiment, in the display control steps ST9 and ST19, the related information In5 for each time period ("Shift 1," "Shift 2," "Shift 3") is displayed on the display device 5. Therefore, a worker who views the related information In5 displayed on the display device 5 can grasp the work efficiency resulting from the splicing work for each time period.
[0094] Furthermore, in the management method according to the first embodiment, in calculation steps ST13, ST15, and ST17, an index for one time period (e.g., "shift 1") is calculated for each of the multiple workers A to C. This makes it possible to calculate an index for each worker for one time period.
[0095] Furthermore, in the management method according to the first embodiment, in the display step ST19, the related information In5 for one time period (e.g., "shift 1") for each of the multiple workers A to C is displayed on the display device 5. This makes it possible to notify each worker of the related information In5 for one time period for each of the multiple workers A to C.
[0096] In the management method according to the first embodiment, in the display control step ST9, the display device 5 displays a message that work training will be provided to the worker in a specific time period selected from among a plurality of time periods. This makes it possible to notify the worker that work training will be provided.
[0097] In particular, if the specific time period is a time period with a low index, it is possible to notify the workers with a low index that work training will be provided.

[0107] (1) Example 1 First, a first operational example of the management device 2 according to the second embodiment will be described with reference to Fig. 8. In the first operational example, a case where there is one worker in each shift will be described as an example.
[0108] The management device 2 executes an acquisition step ST21. In the acquisition step ST21, the acquisition unit 211 of the management device 2 acquires the worker ID information In11 of the target worker (hereinafter referred to as the "target worker") from the barcode reader 4.
[0109] Next, the management device 2 executes a determination step ST22. In the determination step ST22, the control unit 21 of the management device 2 reads out the worker information In1 including the worker ID information In11 acquired by the acquisition unit 211 from the storage device 3, and determines the shift of the target worker based on the shift number information In12 included in the read worker information In1.
[0110] Thereafter, the management device 2 executes one of calculation steps ST23, ST25, and ST27. If the shift of the target worker is "shift 1" (determination step ST22: shift 1), the calculation unit 212 of the management device 2 executes a seventh calculation process in calculation step ST23. The seventh calculation process is a process of calculating the replacement success rate of the target worker in shift 1. Then, the control unit 21 executes a seventh storage process in storage step ST24. The seventh storage process is a process of storing the replacement success rate of the target worker in shift 1 calculated by the calculation unit 212 in the storage device 3 as second work information In3.
[0111] Furthermore, when the target worker's shift is "shift 2" (determination step ST22: shift 2), the calculation unit 212 executes an eighth calculation process in calculation step ST25. The eighth calculation process is a process of calculating the replacement success rate of the target worker in shift 2. Then, the control unit 21 executes an eighth storage process in storage step ST26.

Then, the control unit 21 executes a ninth storage process in storage step ST28. The ninth storage process is a process of storing the replacement success rate of the target worker in shift 3 calculated by the calculation unit 212 in the storage device 3 as second work information In3.
[0113] In the management method according to the second embodiment, steps ST21 to ST28 are executed for all of "Shift 1," "Shift 2," and "Shift 3."
[0114] Finally, the management device 2 executes a display control step ST29. The display control unit 213 of the management device 2 executes a display control process in the display control step ST29. The display control process is a process of controlling the display device 5 so that the display device 5 displays the related information In5.
[0115] (2) Example 2 Next, a second operational example of the management device 2 according to the second embodiment will be described with reference to Fig. 9. In the second operational example, a case where there are three workers (workers A to C) will be described as an example.
[0116] The management device 2 executes an acquisition step ST31. In the acquisition step ST31, the acquisition unit 211 of the management device 2 acquires the worker ID information In11 of the target worker (hereinafter referred to as the "target worker") from the barcode reader 4.
[0117] Next, the management device 2 executes a determination step ST32. In the determination step ST32, the control unit 21 of the management device 2 determines whether the target worker is "Worker A," "Worker B," or "Worker C" based on the worker ID information In11.
[0118] Thereafter, the management device 2 executes one of calculation steps ST33, ST35, and ST37. When the target worker is "worker A" (determination step ST32: worker A), the calculation unit 212 of the management device 2 executes a tenth calculation process in calculation step ST33. The tenth calculation process is a process of calculating the replacement success rate of worker A. Then, the control unit 21 executes a tenth storage process in storage step ST34. The tenth storage process is a process of storing the replacement success rate of worker A calculated by the calculation unit 212 in the storage device 3 as second work information In3.
[0119] Furthermore, when the target worker is "worker B" (determination step ST32: worker B), the calculation unit 212 executes an eleventh calculation process in calculation step ST35. The eleventh calculation process is a process of calculating the replacement success rate of worker B. Then, the control unit 21 executes an eleventh storage process in storage step ST36. The eleventh storage process is a process of storing the replacement success rate of worker B calculated by the calculation unit 212 in the storage device 3 as second work information In3.
[0120] Furthermore, when the target worker is "worker C" (determination step ST32: worker C), the calculation unit 212 executes a twelfth calculation process in a calculation step ST37. The twelfth calculation process is a process of calculating the replacement success rate of worker C. Then, the control unit 21 executes a twelfth storage process in a storage step ST38. The twelfth storage process is a process of storing the replacement success rate of worker C calculated by the calculation unit 212 in the storage device 3 as second work information In3.
[0121] In the management method according to the second embodiment, steps ST31 to ST38 are executed for all of the workers A to C.
[0122] Finally, the management device 2 executes a display control step ST39. The display control unit 213 of the management device 2 executes a display control process in the display control step ST39. The display control process is a process of controlling the display device 5 so that the display device 5 displays the related information In5.
[0123] Incidentally, when there are multiple workers in each shift in Operation Example 1, it is preferable to perform steps ST31 to ST38 in Operation Example 2 in advance. In this case, the calculation unit 212 of the management device 2 can calculate an index for each shift by adding up the indexes (replacement success rates) of the multiple workers in each shift. In this case, the display control step ST29 in Operation Example 1 may or may not be omitted.
[0124] In the management method according to the second embodiment, as in the management method according to the first embodiment, each worker can grasp the work efficiency resulting from the splicing work.
[0125] The various configurations described in the second embodiment can be adopted in appropriate combination with the various configurations (including modified examples) described in the first embodiment.
[0126] (Aspect) The present specification discloses the following aspects.
[0127] The management method according to a first aspect is a method for managing a component mounting apparatus (1) including a component supply device (12) to which multiple component tapes, including a first component tape and a second component tape, are sequentially attached and which supplies multiple components held by each of the multiple component tapes. The management method includes acquisition steps (ST1, ST11, ST21, ST31), calculation steps (ST3, ST5, ST7, ST13, ST15, ST17, ST23, ST25, ST27, ST33, ST35, ST37), and display control steps (ST9, ST19, ST29, ST39). The acquisition steps (ST1, ST11, ST21, ST31) acquire shift information including information about the time period during which a worker performing a splicing operation is engaged. The splicing operation involves splicing the leading end of a second component tape to the trailing end of a first component tape that is attached to the component supply device (12) before the second component tape. In the calculation steps (ST3, ST5, ST7, ST13, ST15, ST17, ST23, ST25, ST27, ST33, ST35, ST37), an index indicating the skill level of the splicing work is calculated based on production results. The production results indicate at least one of errors that occurred during a predetermined period after the component supply device (12) switched from the first component tape to the second component tape and events that reduce the availability of the component mounting device (1). In the display control steps (ST9, ST19, ST29, ST39), related information (In5) related to the index for each of a plurality of time periods is displayed on the display device (5) based on shift information.
[0128] According to this aspect, the related information (In5) relating to the index for each of the multiple time periods is displayed on the display device (5), so that it is possible to grasp the work efficiency resulting from the splicing work.
[0129] In the management method according to the second aspect, in the first aspect, a plurality of workers are engaged in one of a plurality of time periods on one production line (L1, L2) equipped with one or more component mounting devices (1). In the calculation steps (ST13, ST15, ST17, ST33, ST35, ST37), an index for one time period is calculated for each of the plurality of workers.
[0130] According to this aspect, it is possible to calculate an index for each of a plurality of workers in one time period.
[0131] In the management method according to the third aspect, in the second aspect, the display control step (ST19, ST39) causes the display device (5) to display related information (In5) for one time period for each of a plurality of workers.
[0132] According to this aspect, it is possible to notify each worker of the relevant information (In5) of each worker in one time period.
[0133] In the management method according to the fourth aspect, in any one of the first to third aspects, the display control step (ST19, ST39) displays on the display device (5) that work training regarding splicing work will be provided to workers who performed splicing work during a specific time period selected from a plurality of time periods.
[0134] According to this aspect, it is possible to notify the worker that work training will be carried out.
[0135] In the management method according to the fifth aspect, in the fourth aspect, the specific time period is the time period with the lowest index among the plurality of time periods.
[0136] According to this aspect, it is possible to notify the worker in the time period with the lowest index among a plurality of time periods that work training will be implemented.
[0137] A management system (2) according to a sixth aspect manages a component mounting apparatus (1) including a component supply device (12) to which multiple component tapes, including a first component tape and a second component tape, are sequentially attached and which supplies multiple components held on each of the multiple component tapes. The management system (2) includes an acquisition unit (211), a calculation unit (212), and a display control unit (213). The acquisition unit (211) acquires shift information including information about a time period during which a worker performing a splicing operation is engaged. The splicing operation is a process of splicing a starting end of a second component tape to a finishing end of a first component tape that is attached to the component supply device (12) before the second component tape. The calculation unit (212) calculates an index indicating a skill level of the splicing operation based on production results. The production results indicate at least one of errors that occurred during a predetermined period after the component supply device (12) switched from the first component tape to the second component tape and events that reduce the availability of the component mounting apparatus (1). The display control unit (213) causes the display device (5) to display related information relating to the index for each of the plurality of time periods based on the shift information.
[0138] According to this aspect, the related information (In5) relating to the index for each of the multiple time periods is displayed on the display device (5), so that it is possible to grasp the work efficiency resulting from the splicing work.
[0139] The configurations according to the second to fifth aspects are not essential for the management method and can be omitted as appropriate. [Explanation of symbols]
