[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2010-129948 Summary of the Invention [Problem to be solved by the invention]

[0004] In a production line that includes a mounting device for producing circuit boards, a recovery operation is being considered to deal with the error and continue production when an error occurs. Such a recovery operation allows production to continue without stopping even if an error occurs.

[0005] When recovery operations are performed, the production time per circuit board includes the time required for the recovery operations. A mounting device with a high number of errors will experience a slower production speed due to the recovery operations compared to a mounting device with a low number of errors. Therefore, performing recovery operations more than necessary increases the risk of reduced productivity on the production line.

[0006] Therefore, the present disclosure provides a management device, a management method, and a program that can suppress a decrease in productivity of a mounting device due to a recovery operation. [Means for solving the problem]

[0007] A management device according to one aspect of the present disclosure is a management device that manages a mounting device that mounts components on a board, wherein the mounting device is configured to be able to perform recovery operations to deal with errors detected in the components mounted on the board and continue production, and the management device includes a monitoring unit that monitors the production status of the mounting device, and a countermeasure execution unit that, when a decrease in productivity is detected based on the production status in the mounting device that performs the recovery operation, executes processing to change conditions related to the recovery operation.

[0008] A management method according to one aspect of the present disclosure is a management method executed by a mounting device that mounts components on a board, wherein the mounting device is configured to be able to execute recovery operations to deal with errors detected in the components to be mounted on the board and continue production, and the management method monitors the production status of the mounting device, and when a decrease in productivity is detected based on the production status in the mounting device that executes the recovery operation, the management method executes processing to change conditions related to the recovery operation.

[0009] A program according to one aspect of the present disclosure is a program for causing a computer to execute the above-described management method. [Effects of the Invention]

[0010] According to one aspect of the present disclosure, it is possible to realize a management device or the like that can suppress a decrease in productivity of a mounting device due to a recovery operation. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0012] A management device according to a first aspect of the present disclosure is a management device that manages a mounting device that mounts components on a board, and the mounting device is configured to be able to perform recovery operations to continue production in response to errors detected in the components mounted on the board, and the management device includes a monitoring unit that monitors the production status of the mounting device, and a countermeasure execution unit that, when a decrease in productivity is detected based on the production status in the mounting device that performs the recovery operation, executes processing to change conditions related to the recovery operation.

[0013] As a result, if the productivity is reduced due to the recovery operation, the conditions for the recovery operation can be changed, so that the reduction in productivity of the mounting device due to the recovery operation can be suppressed.

[0014] Furthermore, for example, the management device according to the second aspect may be the management device according to the first aspect, wherein a production line is made up of a plurality of production devices including the mounting device, and the management device includes a detection unit that detects the decline in productivity based on the production status of a bottleneck equipment having the longest cycle time among the plurality of production devices that make up the production line, and the number of boards to be produced from the present point in time onwards.

[0015] In this way, since the cycle time of the bottleneck equipment and the remaining number of pieces to be produced are used, a decrease in productivity can be accurately detected.

[0016] Also, for example, the management device according to the third aspect may be the management device according to the first or second aspect, and the countermeasure execution unit may cause the display unit to display information indicating an increase in operating time excluding the time when the mounting device stops production.

[0017] This allows the operator or the like to be notified of information indicating an increase in operating time excluding the time when production is stopped.

[0018] Furthermore, for example, a management device according to a fourth aspect may be the management device according to the third aspect, wherein the mounting device is controlled to repeatedly perform a turn operation of picking up the component and mounting the picked up component on a board, and the countermeasure execution unit may cause the display unit to display a loss time indicating the increase in operating time, based on the time increased by the recovery operation relative to the operation time required for the turn operation, or the number of times the recovery operation has increased relative to a specified number of times the turn operation has been performed.

[0019] This makes it possible to notify the operator of lost time that would be difficult for the operator to notice.

[0020] Also, for example, a management device according to a fifth aspect is a management device according to any one of the first to fourth aspects, and the recovery operation may be at least one of restricting the use of a malfunctioning unit in which the number of errors related to the component is equal to or greater than a specified value, and picking up multiple components that are the target of simultaneous pick-up in multiple pick-up operations.

[0021] This makes it possible to limit the use of malfunctioning units and to suppress a decrease in productivity caused by at least one recovery operation when multiple components that are the target of simultaneous pickup are picked up in multiple pickup operations.

[0022] Also, for example, a management device according to a sixth aspect may be a management device according to any one of the first to fifth aspects, and the process for changing the conditions related to the recovery operation may include a process for changing data indicating the conditions related to the recovery operation.

[0023] This makes it possible to suppress a decrease in productivity of the mounting device due to the recovery operation by changing the data indicating the conditions related to the recovery operation.

[0024] Furthermore, for example, a management device according to a seventh aspect is a management device according to any one of the first to sixth aspects, and the process for changing the conditions related to the recovery operation may include a process of temporarily suspending production of the mounting device and notifying an operator that a malfunctioning unit in which the number of errors related to the component has occurred is to be replaced with a normal unit.

[0025] This allows the operator to replace the malfunctioning unit with a normal unit, thereby preventing a decrease in productivity of the mounting device due to the recovery operation.

[0026] A management method according to an eighth aspect of the present disclosure is a management method executed by a mounting device that mounts components on a board, the mounting device being configured to be able to execute recovery operations to continue production in response to errors detected in the components mounted on the board, the management method monitoring a production status of the mounting device, and when a decrease in productivity is detected based on the production status in the mounting device that executes the recovery operations, executing processing to change conditions for the recovery operations. A program according to a ninth aspect of the present disclosure is a program for causing a computer to execute the management method according to the eighth aspect.

[0027] As a result, the same effects as those of the above-mentioned management device can be achieved.

[0028] These general or specific aspects may be realized as a system, a method, an integrated circuit, a computer program, or a non-transitory recording medium such as a computer-readable CD-ROM, or as any combination of the system, method, integrated circuit, computer program, or recording medium. The program may be pre-stored in the recording medium, or may be supplied to the recording medium via a wide area communication network including the Internet.

[0029] Hereinafter, the embodiments will be specifically described with reference to the drawings.

[0030] The embodiments described below are all comprehensive or specific examples. The numerical values, shapes, components, component placement and connection configurations, steps (processes), and order of steps (processes) shown in the following embodiments are merely examples and are not intended to limit the present disclosure. Furthermore, among the components in the following embodiments, components not described in independent claims are described as optional components.

[0031] Furthermore, each figure is a schematic diagram and is not necessarily an exact illustration. Therefore, for example, the scales of the figures do not necessarily match. Furthermore, in each figure, substantially the same components are given the same reference numerals, and redundant explanations are omitted or simplified.

[0032] Furthermore, in this specification, terms indicating relationships between elements such as "same," as well as numerical values ​​and numerical ranges, are not expressions that express only the strict meaning, but are expressions that also include a substantially equivalent range, for example, a difference of about several percent (or about 10%).

[0033] Furthermore, in this specification, ordinal numbers such as "first" and "second" do not refer to the number or order of components unless otherwise specified, but are used to avoid confusion and distinguish between components of the same type.

[0034] (Embodiment) Hereinafter, a mounting system including a management device according to this embodiment will be described with reference to FIGS.

[0035] [1. Implementation system configuration] First, the configuration of a mounting system according to this embodiment will be described with reference to Figures 1 to 5. Figure 1 is a diagram showing a schematic configuration of a mounting system 10 according to this embodiment. Figure 2 is a block diagram showing the functional configuration of the mounting system 10 according to this embodiment.

[0036] The mounting system 10 is a system for producing circuit boards for electronic devices such as smartphones or personal computers, and produces circuit boards by mounting components such as integrated circuits (ICs), semiconductors, capacitors, and resistors on the boards.

[0037] As shown in FIGS. 1 and 2, the mounting system 10 includes a production line 200, a display unit 210, and a management device 100.

[0038] The production line 200 is a production facility that produces circuit boards by mounting components on boards. As shown in Fig. 1, the production line 200 includes, for example, a board stocker M1, a solder paste printing device M2, mounting devices M3 to M5, a reflow device M6, and an appearance inspection device M7.

[0039] The production line 200 is configured, for example, by connecting multiple production devices in series. In the production line 200, boards are sequentially transported from a board stocker M1 located upstream to downstream production devices, where components are mounted on the boards. For example, each of the mounting devices M3 to M5 is equipped with a mounting head that picks up components and mounts them on the boards. The mounting head is equipped with a memory that stores the head's identification information. The memory stores the number of nozzles attached to the mounting head, data related to bad nozzles (an example of a malfunctioning unit), and the head's identification information in association with each other. Each of the mounting devices M3 to M5 mounts components on boards delivered from an upstream production device and delivers the boards with the mounted components to a downstream device. Each of the mounting devices M3 to M5 is configured to transmit information indicating an error (error information) to the management device 100 when an event occurs in which signals from sensors, cameras, and the timer of the management device 100 equipped in the mounting device deviate from predetermined conditions. The errors in this embodiment include supply errors, suction errors, recognition errors, and transport errors in which the position of the transported substrate is deviated from the predetermined position.

[0040] Furthermore, when an event occurs in which the multiple nozzles of the mounting head cannot simultaneously lower to pick up multiple components due to misalignment of components supplied by the feeder, each of the mounting devices M3 to M5 is configured to transmit information (error information) indicating an error related to the components targeted for simultaneous pickup (hereinafter also referred to as simultaneous pickup failure) to the management device 100. In this way, the management device 100 monitors the production status of the production line 200.

[0041] Each production device, including the board stocker M1, the solder paste printing device M2, the mounting devices M3 to M5, the reflow device M6, and the visual inspection device M7, is communicably connected to a management device 100 that manages each production device via a communication network. Each production device transmits information indicating, for example, the production speed of its own processing and any mistakes or errors that have occurred in its own device to the management device 100. In this way, the management device 100 monitors the production status of the production line 200.

[0042] The above-described multiple production devices provided in the production line 200 are merely examples. Any known production device used in a known production line (mounting line) may be adopted as the production device provided in the production line 200. Furthermore, hereinafter, the mounting devices M3 to M5 will also be referred to as the mounting device M3, etc. Furthermore, hereinafter, any one or more mounting devices among the mounting devices M3 to M5 will also be simply referred to as the mounting device.

[0043] The display unit 210 is a display for displaying various types of information. For example, when the display unit 210 acquires information from the management device 100 and each production device in the production line 200, the display unit 210 displays the acquired information. The display unit 210 displays information indicating an increase in operating time, which will be described later.

[0044] The mounting system 10 may be equipped with one or more display units 210. For example, the mounting system 10 may be equipped with a display unit 210 for each production device included in the production line 200. For example, the display unit 210 may be disposed near each production device. This makes it easier to notify information from the management device 100 to each operator who operates each production device.

[0045] The management device 100 is a device that manages the production devices provided in the production line 200. The management device 100 monitors, for example, a mounting device M3 that mounts components on a board.

[0046] The management device 100 is realized by a computer that includes, for example, a communication interface for communicating with the production line 200, a non-volatile memory that stores programs executed by each processing unit, a volatile memory that is a temporary storage area for executing the programs, an input / output port for sending and receiving signals, and a processor that executes the programs. The communication interface may be realized by a connector to which a communication line is connected for wired communication, or by a wireless communication circuit for wireless communication.

[0047] The management device 100 includes a monitoring unit 110 , a detecting unit 120 , a countermeasure executing unit 130 , an output unit 140 , and a storage unit 150 .

[0048] The management device 100 can access the memory provided in the mounting head from the mounting device to which the mounting head is attached via a communication interface, and acquire various information associated with the head's identification information. The various information may include, for example, data related to bad nozzles.

[0049] The monitoring unit 110 is a processing unit that monitors the production line 200. Specifically, the monitoring unit 110 monitors the production status of the production line 200, which produces circuit boards by mounting components on boards. More specifically, the monitoring unit 110 monitors the production line 200 by acquiring information indicating the production speed of each production device from each production device included in the production line 200. For example, the monitoring unit 110 monitors, as the production status, information that can be generated from the information indicating the production speed. In this embodiment, the monitoring unit 110 monitors, as the production status, information indicating the actual time required for the production device to produce one board (hereinafter also simply referred to as cycle time).

[0050] The monitoring unit 110 acquires error information from, for example, each production device. For example, the monitoring unit 110 monitors the number of errors that occurred in the mounting device M3 and the like, and the number of simultaneous pickup failures.

[0051] Recovery operations are operations to deal with errors detected in components being mounted on boards and continue production. During recovery operations, mounting devices M3 and the like continue production even if the production speed is reduced. Here, errors include mistakes related to components and errors related to components that are the target of simultaneous pickup.

[0052] The following describes the "recovery operation" that the mounting device M3 and the like perform when an error occurs with respect to a component mounted on a board. For example, the recovery operation includes restricting the use of a malfunctioning unit in which the number of component-related errors has exceeded a specified value.

[0053] This can reduce the frequency of production stoppage due to an error (hereinafter also referred to as an error stoppage). At least one of the mounting devices M3, etc. is configured to be able to execute a recovery operation.

[0054] Furthermore, recovery operations are performed by the automatic recovery function of the mounting equipment, eliminating the need for operator intervention in response to errors. When an error is detected, the automatic recovery function reduces the number of error stoppages, preventing significant production downtime, but this may result in a decrease in production speed.

[0055] The mounting device sets a nozzle that has experienced a specified number of component-related errors or more as a bad nozzle that is attached to the mounting head but is not used in production. This causes the nozzle (bad nozzle), an example of a malfunctioning unit, to skip picking up components. The mounting device then continues production by picking up components that were scheduled to be picked up by the bad nozzle with another nozzle equipped in the mounting head. Restricting the use of a nozzle that has experienced a specified number of component-related errors or more is an example of a recovery operation.

[0056] Fig. 3 is a diagram for explaining bad nozzles according to this embodiment. Fig. 3 shows an example in which 16 nozzles n1 to n16 are provided on one mounting head. Fig. 3 shows an example in which the number of misses that each of three nozzles, nozzles n2, n5, and n12, has occurred is equal to or exceeds a specified value, and therefore these three nozzles have been set as bad nozzles by the mounting device.

[0057] In this case, nozzles n2, n5, and n12 are not used for component mounting, so the components that those three nozzles were picking up must be picked up by other nozzles. This allows production to continue even when there are bad nozzles, but it also increases the cumulative number of turns required to produce one board, lengthening the cycle time of the mounting device. This can cause productivity and production costs to shift in the direction of arrow "B" in Figure 5, which will be described later.

[0058] The number of turns refers to the number of times the mounting head repeatedly performs a turn operation to pick up multiple components using multiple nozzles and mount the picked-up components on a board. The mounting device may be controlled to perform multiple turns on one board.

[0059] Next, a "recovery operation" that is executed by the mounting device M3 etc. when an error occurs regarding components that are targets of simultaneous pickup will be described.

[0060] For example, the recovery operation is to pick up multiple components that are the targets of simultaneous pickup in multiple pickup operations.

[0061] The mounting device acquires the center position of each of the multiple components targeted for simultaneous pickup based on an image of the components supplied by the feeder. The mounting device determines whether a correction amount for correcting the misalignment between the center position of the components based on the component image and the center position of the nozzle picking up the components deviates from a predetermined condition. If the correction amount deviates from a predetermined condition, the mounting device detects an error related to the components targeted for simultaneous pickup. Because the pitch (see FIG. 3) between the multiple nozzles (n1 to n16) of the mounting head is fixed, the multiple nozzles may not be able to simultaneously pick up the centers of multiple components due to the relative positions of the component centers and the nozzle centers. If the nozzles are unable to pick up the centers of the components, this may result in the nozzles being unable to pick up the components or the picked up components being positioned incorrectly. Therefore, when the mounting device detects an error related to the components targeted for simultaneous pickup, it picks up the multiple components targeted for simultaneous pickup one by one. In other words, the mounting device picks up multiple components using multiple pickup operations (moving the nozzle up and down). Picking up multiple components targeted for simultaneous pickup using multiple pickup operations is an example of a recovery operation. This can reduce the occurrence of errors, but it also increases the number of times the nozzle has to move up and down, lengthening the cycle time of the mounting device. This can cause productivity and production costs to shift, for example, in the direction of arrow "A" or "B" shown in Figure 5, which will be described later. Note that "increase" means an increase in the number of times beyond the number preset in the production data, etc.

[0062] During recovery operation, production does not stop, so it is difficult for an operator to notice such an increase in cycle time. If the increase in cycle time is noticed too late, there is a risk that production will not be carried out according to the production plan. For this reason, in this embodiment, a detection unit 120 is provided to detect an increase in cycle time, etc.

[0063] The production plan may include the total number of boards to be produced, the types and costs of components used in production, the number of components used per board, the cycle time of the production device that is the bottleneck in production line 200 (i.e., the production device that takes the longest processing time among the multiple production devices included in production line 200), and the cycle time of each production device.The production plan may also include information for detecting a decrease in productivity, such as the normal range of the number of turns required for one mounting head to mount a predetermined number of components, and the above-mentioned predetermined time.

[0064] Referring again to FIG. 2, the detection unit 120 detects a decline in productivity based on the production status of a mounting device that is performing a recovery operation among the multiple production devices that make up the production line 200. The detection unit 120 may detect a decline in productivity based on, for example, the production status of a bottleneck piece of equipment that has the longest cycle time among the multiple production devices that make up the production line 200. The detection unit 120 may also detect a decline in productivity based on the number of boards to be produced in the future (the remaining number of boards to be produced). The detection unit 120 may detect a decline in productivity based on, for example, both the production status and the number of boards produced. The production status here includes a production status that leads to a decline in productivity.

[0065] Productivity refers to performance in terms of time involved in the production of circuit boards. Productivity (specifically, productivity indicators) include, for example, cycle time, operating time or operating rate of the production line 200 or mounting equipment, and production completion time. Note that the cycle time may also be the cycle time of a mounting equipment that is a bottleneck.

[0066] The decline in productivity includes, for example, at least one of an increase in cycle time, a decrease in operation rate, an increase in the number of turns, or a delay in the production completion time of bottleneck equipment on the production line 200. The detection unit 120 monitors at least one of the cycle time, operation rate, number of turns, and production completion time of the production line 200 as the production status of the mounting device undergoing recovery operation, and detects a decline in productivity when it is determined that an increase in cycle time, a decrease in operation rate, an increase in the number of turns, or a delay in the production completion time has occurred.

[0067] Here, the bottleneck facility will be described with reference to Fig. 4. Fig. 4 is a diagram for explaining the bottleneck facility according to this embodiment.

[0068] As shown in FIG. 4, a cycle time is set for each of multiple production equipment. The cycle time may be calculated, for example, by actual measurement. Bottleneck equipment refers to the production equipment with the longest cycle time among multiple production equipment. In the example of FIG. 4, mounting equipment M5, which has the longest cycle time at 35 seconds, is shown as the bottleneck equipment. Note that because the cycle time fluctuates due to recovery operations and the like, bottleneck equipment may be replaced during production.

[0069] When the detection unit 120 evaluates productivity using the remaining number of wafers to be produced, the detection unit 120 may calculate the additional time required for production by multiplying the remaining number of wafers by the value obtained by subtracting the first cycle time based on the production plan from the actual second cycle time, and detecting a decline in productivity based on the second production time, including the additional time, and the first production time in the production plan included in the production plan. The detection unit 120 may detect a decline in productivity, for example, when the second production time is longer than the first production time by a predetermined time or more. The detection unit 120 may also predict a production end time based on the second cycle time and the remaining number of wafers to be produced, and detect a decline in productivity based on the production end time included in the production plan and the predicted production end time. The first cycle time and the second cycle time may be cycle times of different mounting machines.

[0070] In addition, the detection unit 120 may detect a decline in productivity in the following cases: the bottleneck equipment is changed in the production line 200; the cycle time of other equipment approaches the cycle time of the bottleneck equipment and the difference becomes less than a predetermined value; the second cycle time of the bottleneck equipment increases by more than a predetermined time compared to the first cycle time; the second production time due to the increase in the cycle time of the bottleneck equipment increases by more than a predetermined time; or the planned margin time per board shown in the following equation 1 becomes less than a predetermined time.

[0071] Planned margin time per board = (remaining production time - (bottleneck equipment cycle time x remaining number of boards to be produced)) / remaining number of boards to be produced (Equation 1)

[0072] The detection unit 120 may detect a decline in productivity, for example, by determining whether the number of turns of the mounting head has increased compared to the production plan (e.g., whether it has exceeded the normal range) in addition to or instead of the cycle time of the bottleneck equipment. Furthermore, an increase in the number of turns may cause delays in the end times of turns or variations in the end times of turns. The detection unit 120 may detect a decline in productivity, for example, when the end times of turns exceed a predetermined time or when variations in the end times of turns exceed a predetermined time.

[0073] Productivity and production cost will now be described with reference to FIG. 5. FIG. 5 is a diagram illustrating productivity and production cost according to this embodiment. Specifically, FIG. 5 is a graph with production cost on the horizontal axis and productivity on the vertical axis. For example, the graph shown in FIG. 5 is set so that the productivity and production cost set before production line 200 starts producing circuit boards (hereinafter simply referred to as "pre-production") are the origin. Note that the higher the production cost relative to the origin of the graph, the higher the production cost compared to the schedule (production plan) set before production, indicating a deterioration relative to the schedule. Also, the lower the productivity relative to the origin of the graph, the lower the productivity compared to the schedule set before production, indicating a deterioration relative to the schedule. Also, arrow "A" indicates that productivity is mainly reduced due to an error, arrow "B" indicates that production cost improves but productivity is reduced due to an error, and arrow "C" indicates that both productivity and production cost are reduced due to an error.

[0074] For example, the detection unit 120 calculates an evaluation result indicating productivity when recovery operation is being performed based on the acquired production status, and calculates the position of the calculated evaluation result shown in FIG. 5. In other words, the detection unit 120 calculates the coordinates of the calculated evaluation result on a graph. Note that the detection unit 120 may further calculate an evaluation result indicating the production cost when recovery operation is being performed based on the acquired production status. The production cost is the expense required for producing circuit boards by the production line 200.

[0075] If the calculated evaluation result is located in the second quadrant, it can be said that the production state is good in terms of both productivity and production costs relative to the production plan that was planned before production ("Productivity: ○ and Production Cost: ○" in the second quadrant in Figure 5). If the calculated evaluation result is located in the first quadrant, it can be said that the production state is good in terms of productivity but poor in terms of production costs relative to the production plan that was planned before production ("Productivity: ○ and Production Cost: ×" in the first quadrant in Figure 5). If the calculated evaluation result is located in the third quadrant, it can be said that the production cost is good in terms of the production plan that was planned before production but poor in terms of productivity ("Productivity: × and Production Cost: ○" in the third quadrant in Figure 5). If the calculated evaluation result is located in the fourth quadrant, it can be said that the production state is bad in terms of both productivity and production costs relative to the production plan that was planned before production ("Productivity: × and Production Cost: ×" in the fourth quadrant in Figure 5).

[0076] For example, the detection unit 120 may determine that productivity is declining when the calculated evaluation result is located in either quadrant 3 or 4. In other words, the threshold values ​​for determining whether an increase in cycle time, a decrease in availability, an increase in the number of turns, or a delay in the production completion time has occurred may be set so as to be able to determine whether the evaluation result is located in either quadrant 3 or 4.

[0077] Also, for example, suppose that the detection unit 120 calculates a first evaluation result based on the production state at a first time. Next, suppose that the detection unit 120 calculates a second evaluation result based on the production state at a second time after the first time. For example, the detection unit 120 may detect a decrease in productivity of the production line 200 at the second time based on the first evaluation result and the second evaluation result, or may detect a decrease in productivity of the production line 200 at the second time based only on the second evaluation result. The detection unit 120 may detect a decrease in productivity when the second productivity in the second evaluation result is lower than the first productivity in the first evaluation result by a predetermined amount or more, or may detect a decrease in productivity when the productivity in the second evaluation result is lower than a predetermined productivity (e.g., the origin).

[0078] The productivity evaluation result may be calculated, for example, based on the cycle time of the bottleneck equipment. For example, if a second cycle time when circuit boards are actually produced is longer than a first cycle time of the bottleneck equipment predicted (or set) before production of circuit boards begins on production line 200, the productivity is evaluated as low, and if the second cycle time is shorter, the productivity is evaluated as high. The first cycle time is set in advance, for example, by an operator or the like. The second cycle time is the actual cycle time, and can be obtained, for example, by measuring the time from when a board is carried into each of multiple production equipment until the board is carried out of that production equipment.

[0079] The evaluation result of the production cost is that if the second production cost when the circuit boards are actually produced is higher than the first production cost predicted (or set) before production of the circuit boards begins on production line 200, productivity is evaluated as low, and if the second production cost is lower, productivity is evaluated as high.

[0080] Referring back to FIG. 2, the storage unit 150 stores data indicating conditions for the recovery operation. The data indicating the conditions for the recovery operation includes at least one of a parameter related to bad nozzle settings (the number of bad nozzles that can be set as bad nozzles), a simultaneous pickup parameter indicating that a component is a target for simultaneous pickup (ON / OFF of simultaneous pickup prohibition), a parameter related to re-pickup for re-pickup of a component when a component-related error occurs (number of re-pickup attempts), and a parameter related to pickup position teaching for acquiring the center position of the outline of a component supplied by a feeder when a component-related error occurs (ON / OFF of pickup position teaching, number of pickup position teaching attempts). The storage unit 150 may store the parameters related to the bad nozzle settings in association with head identification information. The storage unit 150 may store the simultaneous pickup parameter, the parameter related to re-pickup, the parameter related to pickup position teaching, and the component parameter in association with each other. The component parameter is either a component ID that identifies the component or the component type. The mounting device is configured to perform the recovery operation in accordance with the conditions for the recovery operation stored in the storage unit 150.

[0081] When the detection unit 120 detects a decrease in productivity in the production line 200, the countermeasure execution unit 130 executes a process to identify malfunctioning units attached to the production equipment. For example, the countermeasure execution unit 130 acquires data related to malfunctioning units from the production equipment and stores the data related to the malfunctioning units in the storage unit 150. More specifically, the countermeasure execution unit 130 acquires data related to bad nozzles from the mounting equipment. The data related to bad nozzles includes information indicating the number of bad nozzles provided in the mounting head and the arrangement numbers of the nozzles to which the bad nozzles are attached. The arrangement numbers are information indicating the positions at which the nozzles are attached in the mounting head. This allows the management device 100 to identify the bad nozzles attached to the production equipment.

[0082] Then, the countermeasure execution unit 130 executes a process for changing the data indicating the conditions for the recovery operation. As the process for changing the data indicating the conditions for the recovery operation, the countermeasure execution unit 130 may relax the restrictions on the recovery operation or may suggest replacing the unit.

[0083] Changing the conditions includes changing the data indicating the conditions related to the recovery operation stored in the storage unit 150. Replacing a unit means replacing a malfunctioning unit with a normal unit.

[0084] For example, the countermeasure execution unit 130 changes parameters related to the bad nozzle settings as a condition for recovery operation because, for example, an increase in the number of bad nozzles attached to a mounting device increases cycle time and reduces productivity. For example, the countermeasure execution unit 130 may (countermeasure 1) reduce the number of bad nozzles set. Furthermore, the countermeasure execution unit 130 may suggest replacing the bad nozzles attached to the mounting device. For example, the countermeasure execution unit 130 may (countermeasure 2) suggest to the operator that the bad nozzles be lined out, or (countermeasure 3) suggest to the operator that the nozzle placement number of the bad nozzles be changed. For example, when one mounting device has two or more mounting heads, changing the nozzle placement number includes attaching a bad nozzle attached to one mounting head to another mounting head. Furthermore, when a production line has multiple mounting devices, changing the nozzle placement number includes attaching a bad nozzle attached to a mounting head of one mounting device to a mounting head of another mounting device.

[0085] (Measure 1) reduces the number of bad nozzles set, which helps prevent a decline in productivity due to restrictions on the use of multiple nozzles. (Measures 2) and (Measures 3) temporarily interrupt production during replacement work, but can improve productivity after replacement.

[0086] The proposal to replace a bad nozzle is made, for example, when the countermeasure execution unit 130 checks the nozzle inventory and there is inventory. The nozzle exchange between facilities is made, for example, when the own device is a bottleneck facility. Note that making a proposal may mean, for example, having the display unit 210 display the contents of the proposal. Furthermore, the management device 100 may acquire an input from the operator regarding the contents of the proposal. The input may include information indicating whether the contents of the proposal can be implemented.

[0087] When the detection unit 120 detects a decrease in productivity, the countermeasure execution unit 130 executes one of (Countermeasure 1) to (Countermeasure 3). Furthermore, if two or more bad nozzles are set in one mounting head, the countermeasure execution unit 130 lifts the usage restriction on one or more of the two or more bad nozzles. The countermeasure execution unit 130 may, for example, sequentially lift the usage restriction on the bad nozzles until the productivity in the graph shown in FIG. 5 rises above the origin.

[0088] Furthermore, for example, if the recovery operation increases the number of pickup operations (up and down movements of the nozzle when the mounting head picks up components) in one turn, productivity will decrease. Therefore, the countermeasure execution unit 130 suggests work items for the operator related to units such as feeders, mounting heads, and nozzles that supply components targeted for simultaneous pickup (components for which the simultaneous pickup parameter is ON). For example, the countermeasure execution unit 130 may (Countermeasure 4) instruct the operator to reset the component reel in the feeder, or (Countermeasure 5) instruct the operator to perform maintenance such as cleaning the unit. Furthermore, if the nozzle picking up the components targeted for simultaneous pickup is a bad nozzle, the countermeasure execution unit 130 may (Countermeasure 6) lift the usage restriction on the bad nozzle, or may suggest to the operator either (Countermeasure 2) or (Countermeasure 3), which involve replacing the bad nozzle.

[0089] (Measure 4) will temporarily interrupt production for resetting work, but it will improve productivity as a whole. (Measure 5) will temporarily interrupt production for cleaning, etc., but it will improve productivity as a whole. (Measure 6) will temporarily interrupt production, but it will improve productivity as a whole.

[0090] Incidentally, giving an instruction may mean, for example, having the display unit 210 display the instruction content.

[0091] Furthermore, for example, when mounting components using a unit that is not malfunctioning but has undergone an increased number of recovery operations, productivity decreases. Therefore, the countermeasure execution unit 130 may change at least one of the parameters related to pickup position teaching and the parameters related to re-pickup as conditions for the recovery operation. More specifically, the countermeasure execution unit 130 may (Countermeasure 7) reduce at least one of the number of re-pickups and the number of pickup position teachings. Although (Countermeasure 7) temporarily interrupts production due to the error stop recovery work, by taking countermeasures for units where operators frequently make mistakes, productivity of the entire production can be improved. Furthermore, the countermeasure execution unit 130 may (Countermeasure 8) set the pickup position teaching to OFF so that the mounting device does not perform pickup position teaching even if a component supply error occurs. Although (Countermeasure 8) temporarily interrupts production due to the error stop recovery work if pickup position teaching is not performed, by taking countermeasures for units where operators frequently make mistakes, productivity of the entire production can be improved.

[0092] The above measures 1, 6, 7, and 8 are examples of processing for relaxing the conditions for recovery operations. Also, the above measures 2 to 5 are examples of processing for making an operator deal with a unit that executes recovery operations.

[0093] In addition, a table in which the contents of recovery operations and the contents of processing for changing the conditions related to the recovery operations are associated is stored in the storage unit 150, and the countermeasure execution unit 130 may determine the contents of processing for changing the conditions related to the recovery operations based on the table and the contents of the recovery operations.

[0094] The output unit 140 is a processing unit that outputs various information. For example, the output unit 140 outputs information for changing the conditions related to the recovery operation performed by the countermeasure execution unit 130 to at least one of the production line 200 and the display unit 210 via a communication interface provided in the management device 100. As a result, for example, when the conditions for the recovery operation of the production line 200 differ from the conditions for the recovery operation stored in the storage unit 150 based on the information, the output unit 140 can cause the production line 200 to perform the recovery operation in accordance with the conditions for the recovery operation stored in the storage unit 150, or can cause an operator of the production line 200, etc., to display the information via the display unit 210. Note that the output unit 140 may output the information for changing the conditions related to the recovery operation to an external server, etc.

[0095] Processing units such as the monitoring unit 110, the detection unit 120, the countermeasure execution unit 130, and the output unit 140 are realized, for example, by a memory that stores the control programs executed by each processing unit, and a processor that executes the control programs.

[0096] The storage unit 150 is a storage device that stores various types of information. The storage unit 150 stores information indicating, for example, productivity, production plans, etc. The storage unit 150 is realized by, for example, a flash memory or an HDD (Hard Disk Drive).

[0097] As described above, for example, the management device 100 detects a decrease in productivity while the mounting device is performing a recovery operation. Furthermore, the management device 100 manages the current position in the coordinates of the evaluation result while the recovery operation is being performed.

[0098] [2. Operation of the implemented system] Next, the operation of the mounting system 10 configured as above will be described with reference to Figures 6 to 8. Figure 6 is a flowchart showing the operation (management method) executed by the management device 100 according to this embodiment.

[0099] 6, the monitoring unit 110 of the management device 100 monitors the production status, such as the cycle time, of the production line 200 (S11). The monitoring unit 110 may periodically monitor the production status.

[0100] Next, the countermeasure execution unit 130 outputs information indicating an increase in the operating time according to the content of the recovery operation to the display unit 210 via the output unit 140 (S12). The operating time may be the operating time excluding the time during which the mounting device stops production, or may be the production time including the time during which the mounting device stops production.

[0101] For example, the countermeasure execution unit 130 may output information indicating lost time as information indicating an increase in operating time to the display unit 210 via the output unit 140 based on at least one of the time increased by the recovery operation relative to the operation time required for the turn operation and the number of times the recovery operation has increased relative to the specified number of turn operations.

[0102] The time increased by a recovery operation includes, for example, the time increased by at least one of re-pickup and pick-up position teaching, the time increased by picking up multiple components that are to be picked up simultaneously using multiple pick-up operations (up and down movements of the mounting head), etc. The number of times increased by a recovery operation includes the number of turns increased by picking up a component that was supposed to be picked up by a bad nozzle, bad head, etc. using a different nozzle or head.

[0103] As a result, the countermeasure execution unit 130 can notify the operator that productivity is declining by displaying information indicating the lost time on the display unit 210. For example, the operator can be prompted to take measures according to the lost time. Declines in productivity can be effectively suppressed by having the operator who has confirmed the lost time take measures according to the lost time.

[0104] Fig. 7 is a diagram for explaining loss time according to this embodiment. Fig. 7(a) shows the actual production time when a recovery operation is performed during production, Fig. 7(b) shows the actual operation time (the time during which the equipment is operating and the production line 200 is producing) obtained by subtracting the equipment stop time (stop time) from the production time shown in Fig. 7(a), and Fig. 7(c) shows the operation time based on the production plan.

[0105] The operating time based on the production plan is the ideal operating time calculated by multiplying the cycle time of the production line 200 linked to the production plan by the number of wafers produced. Equipment downtime is an example of the time during which the mounting device stops production due to recovery work after an error stop or due to a parts shortage, and lost time is an example of information indicating the increase in operating time excluding the time when the mounting device stops production.

[0106] 7(a), the production time includes a first time p1, a third time p3, and a fifth time p5 during which the production line 200 is performing production, and a second time p2 and a fourth time p4 during which the production line 200 is halting production. The first time p1 is the time during which production is performed according to the production plan, and the third time p3 and the fifth time p5 are times that include the time increased by recovery operations. In other words, the third time p3 and the fifth time p5 are times during which productivity is reduced to a certain extent due to the recovery operations.

[0107] Figure 7(b) shows the operating time during which the production line 200 is performing production out of the production time shown in Figure 7(a). Specifically, the net operating time shown in Figure 7(b) is the sum of the first time p1, the third time p3, and the fifth time p5 shown in Figure 7(a).

[0108] As shown in Figure 7(b) and (c), the lost time is calculated as the difference between the net operating time and the operating time based on the production plan. The lost time calculated in this way indicates the operating time extended by the recovery operation.

[0109] The countermeasure execution unit 130 displays at least the operating time extended by the recovery operation, that is, the lost time due to the recovery operation, on the display unit 210. The countermeasure execution unit 130 may display the lost time numerically or in the form of a graph as shown in Fig. 7. In this way, the countermeasure execution unit 130 can notify the operator of the extended time due to the recovery operation, which the operator may not easily notice.

[0110] The calculated loss time may be the loss time at the current time, or the loss time at the end of production if production continues as is. The loss time at the end of production if production continues as is may be predicted by subtracting the operating time based on the production plan from the total time of the time required for production up to the current time and the remaining production time calculated by multiplying the current cycle time of the bottleneck equipment by the remaining number of sheets to be produced.

[0111] The lost time may include at least one of a time when the cycle time increases, a time when the net operating time increases, and a time when the planned margin time decreases.

[0112] 6 again, next, the detection unit 120 determines whether or not productivity has decreased based on the production status such as the cycle time of the mounting device (S13). The detection unit 120 may periodically perform the determination of step S13.

[0113] Next, if the detection unit 120 detects a decrease in productivity (Yes in S13), the countermeasure execution unit 130 identifies the malfunctioning unit attached to the production equipment (S14), and then executes a process to change the conditions for the recovery operation (S15).

[0114] Furthermore, if a decrease in productivity has not been detected (No in S13), the management apparatus 100 ends the process.

[0115] Fig. 8 is a flowchart showing the detailed operation (management method) of step S15 shown in Fig. 6. Fig. 8 explains a case where a bad nozzle is attached to the mounting device as a malfunctioning unit, and two or more nozzles among a plurality of nozzles attached to the mounting head are bad nozzles.

[0116] 8, the countermeasure execution unit 130 calculates the backlog (remaining number of production sheets) when an error occurs based on the production plan and the number of sheets produced up to the present time, and determines whether the calculated backlog is equal to or greater than a predetermined number (S151). The predetermined number is set in advance and stored in the storage unit 150.

[0117] Next, when it is determined that the backlog is equal to or greater than a predetermined number (Yes in S151), the countermeasure execution unit 130 determines whether or not the mounting device having the bad nozzle is a bottleneck facility in the production line 200 (S152). The determination of whether or not the mounting device is a bottleneck facility is made taking into consideration an increase in cycle time due to two or more bad nozzles in the mounting device.

[0118] Next, if the countermeasure execution unit 130 determines that the mounting device is a bottleneck facility (Yes in S152), it decides to change the nozzle arrangement number (S153). When this change is made, the cycle time of the new mounting device becomes longer, but the cycle time of the bottleneck mounting device becomes shorter, thereby improving the productivity of the production line 200. Note that if the production line 200 includes multiple mounting devices, the countermeasure execution unit 130 may suggest, for example, replacing the bad nozzle attached to the bottleneck mounting device with the nozzle attached to the mounting device with the shortest cycle time.

[0119] Furthermore, if the countermeasure execution unit 130 determines that the equipment is not a bottleneck (No in S152), it decides to propose line-out of the bad nozzle (S154). Although it is necessary to stop the production line 200 to line-out the bad nozzle, since there is a large amount of backlog, it is possible to shorten the production time compared to continuing the recovery operation.

[0120] Furthermore, when it is determined that the backlog is less than a predetermined number (No in S151), the countermeasure execution unit 130 decides to reduce the number of bad nozzles set (S155). Since the backlog is small, the countermeasure execution unit 130 improves productivity by reducing the number of bad nozzles set rather than replacing the bad nozzles.

[0121] Next, the output unit 140 outputs the proposal content determined by the countermeasure execution unit 130 (S156). The output unit 140 outputs, for example, the proposal content determined in steps S153 and S154 to a terminal device (for example, the display unit 210) of an operator or the like. In addition, the output unit 140 outputs, for example, the proposal content determined in step S155 to the production line 200.

[0122] In this way, when a decrease in productivity is detected while the mounting device is continuing production through recovery operation, a process is executed to change the conditions depending on whether there is backlog or whether the equipment is a bottleneck. Therefore, the management device 100 can suppress a decrease in productivity in the mounting device undergoing recovery operation by changing the conditions depending on whether there is backlog or whether the equipment is a bottleneck.

[0123] (Other embodiments) While the management device and the like according to one or more aspects have been described above based on the embodiments, the present disclosure is not limited to these embodiments. As long as they do not deviate from the spirit of the present disclosure, various modifications conceivable by those skilled in the art to the present embodiments and configurations constructed by combining components of different embodiments may also be included in the present disclosure.

[0124] For example, the management device according to the above embodiment may be installed in a factory where a production line is installed, or may be installed outside the factory.

[0125] Furthermore, in the above embodiment, an example has been described in which the monitoring unit 110 monitors the production status of a mounting device, but it is sufficient to monitor at least the production status of the production device with the longest expected cycle time among the multiple production devices that make up the production line 200. For example, the monitoring unit 110 may also monitor the production status of a production device that is not a mounting device.

[0126] Furthermore, in the above embodiment, an example has been described in which monitoring unit 110 monitors cycle time as the production status, but monitoring unit 110 may monitor information other than cycle time as long as it can be generated from information indicating the production speed. For example, monitoring unit 110 may monitor, as the production status, information indicating the actual time required to mount one component on a production device (also called takt time) or information indicating the predicted time when production of multiple boards of one board type will be completed on a production device.

[0127] The monitoring unit 110 may also compare the production rate acquired from the production equipment with a target production rate, and determine the current operating status of the production equipment based on the comparison result. In this case, the monitoring unit 110 may monitor the operating status of the production equipment, such as "operating (as planned)" or "operating (increased cycle time)", as the production state.

[0128] In the above embodiment, the monitoring unit 110 monitors the number of misses or simultaneous pick-up failures. However, any information that can be generated from error information may be used. For example, the monitoring unit 110 may monitor at least one of the pickup success rate, in which a nozzle successfully picks up a component, and the success rate of the recovery operation, for each nozzle, each feeder, or each component. The number of misses or simultaneous pick-up failures may be the number per hour, the number per feeder, the number per nozzle, the number per head, or the cumulative number.

[0129] Furthermore, in the above embodiment, an example has been described in which a decline in productivity is detected mainly when the cycle time of bottleneck equipment increases, but a decline in productivity may also be detected, for example, when the cycle time of a mounting device that is not bottleneck equipment increases by more than a predetermined time.

[0130] Furthermore, in the above embodiment, the management device determines whether productivity has declined in step S15, but, for example, the operator may be asked to determine whether productivity has declined, and the determination result as to whether productivity has declined in step S15 may be obtained based on input from the operator.

[0131] The management device in the above embodiment may also include a user interface (not shown) such as a mouse and keyboard, and may acquire various information from an operator via the user interface.

[0132] Furthermore, the production line in the above embodiment may be connected via a network to a computer that performs processing to acquire information from each production device, and the computer may be configured to acquire information indicating the production speed and error information from the production devices, and thereby execute processing to generate information linking the production speed to identification information of the substrates and information linking the number of errors or simultaneous suction collapses to identification information of the feeders. In other words, the function of the monitoring unit may be realized by executing such processing by the computer.

[0133] Furthermore, although the malfunctioning unit in the above embodiment is described as a nozzle (bad nozzle) by way of example, it may be any unit used for mounting components. For example, the malfunctioning unit may be a mounting head, a stage provided in a board transport mechanism, a component recognition camera, a feeder, or a carriage to which a feeder is attached. Restricting the use of these units is an example of a recovery operation.

[0134] In the above 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 or processor reading and executing a software program recorded on a recording medium such as a hard disk or semiconductor memory.

[0135] Furthermore, the order in which each step in the flowchart is executed is merely an example for specifically explaining the present disclosure, and an order other than the above may be used. Furthermore, some of the steps may be executed simultaneously (in parallel) with other steps, or some of the steps may not be executed. For example, the process of step S14 shown in FIG. 6 may not be executed.

[0136] The division of functional blocks in the block diagram is an example, and multiple functional blocks may be realized as a single functional block, one functional block may be divided into multiple blocks, or some functions may be moved to another functional block.Furthermore, the functions of multiple functional blocks having similar functions may be processed in parallel or time-shared by a single piece of hardware or software.

[0137] Furthermore, the management device according to the above-described embodiments may be realized as a single device or may be realized by multiple devices. When the management device is realized by multiple devices, the components of the management device may be distributed among the multiple devices in any manner. When the management device is realized by multiple devices, the communication method between the multiple devices is not particularly limited, and may be wireless communication or wired communication. Furthermore, wireless communication and wired communication may be combined between the devices.

[0138] Furthermore, each of the components described in the above embodiments may be realized as software, or may be realized as an LSI, which is typically an integrated circuit. These may be individually integrated into a single chip, or some or all of them may be integrated into a single chip.

[0139] Another aspect of the present disclosure may be a computer program that causes a computer to execute each of the characteristic steps included in the management method shown in either FIG. 6 or FIG.

[0140] Furthermore, for example, the program may be a program to be executed by a computer. Another aspect of the present disclosure may be a computer-readable non-transitory recording medium on which such a program is recorded. For example, such a program may be recorded on a recording medium and distributed or circulated. For example, the distributed program may be installed in a device having another processor, and the program may be executed by the processor, thereby causing the device to perform each of the above processes.

[0141] The present disclosure may also be realized as a method for manufacturing a circuit board including the management method described in the above embodiment. [Industrial Applicability]

[0142] The present disclosure can be used in an apparatus for managing a mounting line that mounts components on a board. [Explanation of symbols]
