Abstract
Description
Technical Field
[0001] This disclosure relates to a component management device and a component management method.
Background Art
[0002] When producing a substrate on which a large number of components are mounted, it is generally common to configure a production line (SMT (Surface Mounting Technology) line). The production line is configured by connecting devices such as a solder printing device, an electronic component mounting device, a reflow device, and a substrate inspection device.
[0003] Among the components used in such a production line, there are those called MSD (Moisture Sensitive Device) components, which have the characteristic of deteriorating by absorbing moisture in the air. The MSD components have a defined floor life (indoor storage life), and it is necessary to mount them on the substrate before the floor life expires.
[0004] Patent Document 1 discloses a device that determines the management mode of MSD components in consideration of the scheduled time of completion of use and the floor life of the MSD components.

[0006] By the way, in one production, the MSD components may not be used up and some may remain. Patent Document 1 does not disclose the management mode of the remaining MSD components after the production is completed.

[Effects of the Invention]

[0012] The embodiments described below will be explained with reference to the drawings. The embodiments described below are all comprehensive or specific examples. The numerical values, shapes, materials, components, arrangement and connection forms of components, steps (processes), and the order of steps (processes) shown in the embodiments below are examples and are not intended to limit the disclosure. Furthermore, among the components in the embodiments below, components not described in an independent claim will be described as optional components.
[0013] Furthermore, each figure is a schematic diagram and not necessarily a strictly accurate representation. In addition, the same reference numerals are used for substantially identical components in each figure, and redundant explanations may be omitted or simplified.
[0014] Furthermore, in this specification, numerical values and numerical ranges do not represent only strict meanings, but also include substantially equivalent ranges, such as differences of a few percent (e.g., about 10%).
[0015] (Embodiment) The parts management system according to this embodiment will be described below with reference to Figures 1 to 6.
[0016] [1. Configuration of the parts management system] First, the configuration of the parts management system according to this embodiment will be described with reference to Figures 1 to 5. Figure 1 is a block diagram showing the functional configuration of the parts management system 1 according to this embodiment.
[0017] As shown in FIG. 1, the component management system 1 includes a management device 20, a storage 30, a drying device 40, a display device 50, and an information terminal 60. The component management system 1 is a system for managing components used in a component mounting line 10 for mounting components on a substrate in a factory.
[0018] The component mounting line 10 is a production line for performing predetermined operations such as mounting components on an object such as a substrate. The component mounting line 10 is configured by connecting various production devices that perform operations such as substrate supply, solder printing work, component mounting work, and reflow work. The components are, for example, electronic components. Note that the component mounting line 10 may be included in the component management system 1.
[0019] The management device 20 is a device for managing components used in the component mounting line 10. In the present embodiment, the management device 20 manages the use of MSD components (humidity management components) that require humidity management. Specifically, the management device 20 manages the use of MSD components remaining after being used in production, that is, MSD components remaining in production. Hereinafter, MSD components remaining after being used in production are also referred to as remaining components. The management device 20 is an example of a component management device.
[0020] MSD components are, for example, package components previously sealed with resin, and these package components are highly humidity-sensitive devices in which humidity has a great impact on the mounting quality after reflow. Also, MSD components are components that require low-humidity storage. For example, they are stored in a humidity-controlled storage 30 in a moisture-proof packaged state to maintain a dry state. In a space where humidity management is not sufficient, such as the space where the component mounting line 10 is located, it is necessary to use up the components within the floor life (indoor storage life) after opening the moisture-proof package.
[0021] Floor life is a type of indicator that shows the lifespan of an electronic component (in this case, an MSD component). It refers to the time that an MSD component can withstand environments with humidity levels above a specified level (for example, the maximum time it can be exposed to air), and is defined, for example, by the Moisture Sensitivity Level (MSL). MSL is a standard established by JEDEC (Joint Electron Device Engineering Council) with the aim of preventing failure caused by volume expansion due to the vaporization of moisture contained in the component.
[0022] MSL levels are divided into levels 1 through 6, with a floor life set for each level. Level 1 has an unlimited floor life, Level 2 has a floor life of one year, Level 2a has a floor life of four weeks, Level 3 has a floor life of 168 hours (one week), Level 4 has a floor life of 72 hours (three days), Level 5 has a floor life of 48 hours (two days), Level 5a has a floor life of 24 hours (one day), and Level 6 is a special specification, for example, for use after baking. The MSL level of an MSD part may be determined by the user of the MSD part (e.g., a worker) or recommended by the manufacturer of the MSD part.
[0023] Furthermore, floor life is not limited to being set by the MSL level; it may also be set arbitrarily by the user.
[0024] Furthermore, the remaining floor life, as described later, indicates the remaining floor life. For example, the remaining floor life indicates the remaining time that an MSD component can withstand an environment with a humidity level above a specified level. It can also be said that the remaining floor life indicates the remaining time that an MSD component can be exposed to an uncontrolled humidity environment (exposed to the atmosphere). The remaining floor life is the floor life minus the cumulative exposure time that the MSD component has been exposed to the atmosphere, or the time elapsed since the moisture-proof packaging was opened. The initial value of the remaining floor life of an MSD component is set to, for example, the floor life duration.
[0025] The control device 20 is connected to the component mounting line 10, storage unit 30, drying unit 40, display device 50, and information terminal 60 in a manner that allows communication between them.
[0026] The management device 20 comprises an acquisition unit 21, a determination unit 22, a storage unit 23, and an output unit 24. The management device 20 is configured to include a microcontroller (i.e., an IC equipped with a processor and memory), and each function of the management device 20 is realized by the processor executing a computer program stored in memory.
[0027] The acquisition unit 21 acquires various information for determining the management method of remaining parts. The acquisition unit 21 acquires production plan information T1, which shows the production plan in the parts mounting line 10, and floor life remaining time information, which shows the remaining floor life of MSD parts. The acquisition unit 21 is configured to include a communication circuit (communication module).
[0028] The production plan information T1 will be explained with reference to Figure 2, which will be described later. The production plan information T1 may be obtained from a device that generates production plan information, or it may be obtained through input from a user or other party.
[0029] The remaining floor life information is included in the component information T3 and will be explained later with reference to Figure 4. The remaining floor life information may be obtained, for example, from a device that manages the remaining floor life, or by measuring and calculating the time the management device 20 is exposed to the atmosphere, or by input from a user or the like.
[0030] The decision unit 22 determines the management method for remaining parts after production is completed, based on the production plan information and the remaining floor life time information. For example, the decision unit 22 determines the management method for remaining parts based on the cumulative exposure time and the remaining floor life time. Here, the management method is one of the following: use in the next production, notify the worker, store in a dry box (storage unit 30 in this embodiment), or store in a drying device 40.
[0031] The storage unit 23 is a storage device that stores various information for determining the management method of remaining parts. In this embodiment, the storage unit 23 stores production plan information T1, mounting data T2, and part information T3. The production plan information T1 and part information T3 are acquired, for example, from an external device via the acquisition unit 21 after production is completed, but are not limited to this. The storage unit 23 is implemented by a semiconductor memory or the like, but is not limited to this.
[0032] Here, we will explain the various types of information stored in the memory unit 23 with reference to Figures 2 to 4. First, we will explain the production plan information T1 with reference to Figure 2. Figure 2 is a diagram showing an example of the production plan information T1 according to this embodiment.
[0033] As shown in Figure 2, the production plan information T1 includes the production plan ID, start time (e.g., start date and time), end time (e.g., end date and time), production line name, board name, and number of boards to be produced. The production plan information T1 includes information about the production to be carried out after the current production (the next production). The production plan information T1 may also include information about the current production. The production plan information T1 shown in Figure 2 will be explained assuming that it shows information about the schedule. Note that the current production is an example of the first production, and the next production is an example of the second production.
[0034] The production plan ID indicates identification information for each production plan. The production plan ID may be set for each production lot, for example.
[0035] The start date and time indicate the scheduled start date and time for production. Note that Figure 2 only shows the start time.
[0036] The end date and time indicate the scheduled end date and time for production. Note that Figure 2 only shows the end time.
[0037] The production line name indicates identification information to identify the component mounting line 10 to be used, in the case of multiple component mounting lines 10.
[0038] The board name indicates identification information used to identify the board on which components will be mounted. The board name may be, for example, a unique number corresponding to the production plan ID, a board model number, or a board type.
[0039] The production quantity indicates the number of circuit boards on which components will be mounted.
[0040] In the example in Figure 2, production plan information T1 contains information about two productions with production plan IDs "100" and "200". Production plan ID "100" has a start time of "9:00", an end time of "9:50", a production line name of "1", a board name of "A", and a production quantity of "500" units. Production plan ID "200" has a start time of "10:00", an end time of "10:50", a production line name of "2", a board name of "B", and a production quantity of "1000" units.
[0041] The production plan information T1 may be updated. For example, if current production is behind schedule, the start date and end time shown in Figure 2 may be updated according to the production delay. The production plan information T1 may be updated, for example, by the control device 20, or by obtaining the updated production plan information T1 from the device that generates the production plan information T1.
[0042] Furthermore, production plan information T1 includes at least one of the production plans that use MSD parts and the production plans that do not use MSD parts.
[0043] Next, the implementation data T2 will be explained with reference to Figure 3. Figure 3 is a diagram showing an example of the implementation data T2 according to this embodiment.
[0044] As shown in Figure 3, the mounting data T2 includes information such as the mounting position when mounting components on the substrate. The mounting data T2 includes the substrate name, coordinate data, and scheduled production time.
[0045] The board name indicates identification information used to identify the board on which components will be mounted. The board name may also be, for example, the board's model number or board type.
[0046] The coordinate data indicates the mounting position of a component on the circuit board and includes X (X-coordinate), Y (Y-coordinate), θ (rotation angle), and the component ID. The component ID is identification information for identifying a component and may be the component's model number, component type, etc. For example, the component ID is identification information for identifying an MSD component.
[0047] The planned production time indicates the time it takes to use the parts (for example, the production time required for production).
[0048] In the example in Figure 3, the mounting data T2 contains information about two circuit boards, named "A" and "B". For circuit board "A", it indicates that MSD components with component IDs "001" to "004" will be mounted at the positions indicated by the coordinate data, and that production (e.g., production of one lot) is expected to take X hours. For circuit board "B", it indicates that MSD components with component IDs "001" and "002" will be mounted at the positions indicated by the coordinate data, and that production (e.g., production of one lot) is expected to take Y hours.
[0049] Next, we will explain the component information T3 with reference to Figure 4. Figure 4 is a diagram showing an example of component information T3 according to this embodiment.
[0050] As shown in Figure 4, part information T3 includes various information for each MSD part. Part information T3 includes information for determining how to manage remaining parts after production is completed. Part information T3 includes part ID, remaining quantity, floor life, cumulative exposure time, remaining floor life time, and reservation status. Part information T3 also includes floor life time information indicating the remaining floor life time.
[0051] The part ID is information used to identify an MSD part, and may include the part number or type of the MSD part.
[0052] The remaining quantity indicates the number of MSD parts contained in a container, if the MSD parts are contained in a container. The container is, for example, a bulk case that stores chip-shaped MSD parts in a loose state (stores MSD parts in bulk), or a taping case that stores parts with carrier tape attached.
[0053] As mentioned above, floor life is the time that an MSD component can withstand an environment with a humidity level above a specified level, and it is a time corresponding to the MSL level of the MSD component.
[0054] Cumulative exposure time indicates the total time the component has been exposed to the atmosphere up to this point. Cumulative exposure time is, for example, the total time the component was outside the storage unit 30 if it has been taken in and out of the storage unit 30 multiple times.
[0055] The remaining floor life is calculated by subtracting the cumulative exposure time from the floor life. The remaining floor life shown in Figure 4 is, for example, the value at the end of the current production cycle.
[0056] The reservation status indicates the time when the MSD parts are scheduled to be used. Part IDs "001" and "002" indicate that they are scheduled to be used in two production runs, while part IDs "003" and "004" indicate that they are scheduled to be used in one production run.
[0057] In the example in Figure 4, information about four MSD parts with part IDs "001" to "004" is included in part information T3. For part ID "001", the remaining quantity is "500", the floor life is "48H (48 hours)", the current cumulative exposure time is "10H", the current remaining floor life is "38H", and the reservation status is "9:00~9:50" and "10:00~10:50". The same applies to part IDs "002" and beyond, and their explanation is omitted. The second production after the first production refers to the production from "9:00~9:50" and the production from "10:00~10:50", or either of them.
[0058] Furthermore, the part information T3 may include, for example, information on MSD parts currently in use in production, as well as information on MSD parts stored in the storage unit 30.
[0059] Note that the floor life, cumulative exposure time, and remaining floor life shown in Figure 4 are common times for multiple MSD components housed in the containment.
[0060] Referring again to Figure 1, the output unit 24 outputs the remaining parts management pattern determined by the determination unit 22 to the display device 50 or information terminal 60. The output unit 24 is configured to include a communication circuit (communication module).
[0061] The control device 20 may also include, for example, a timing unit that measures the time that the MSD component is exposed to the atmosphere.
[0062] The storage unit 30 is a device for storing MSD components at a predetermined humidity level and is equipped with a humidity control function that keeps the internal humidity at a specified low humidity level at all times. During the period that an MSD component is stored in the storage unit 30, the cumulative exposure time is not counted. In other words, during the period that an MSD component is stored in the storage unit 30, the remaining floor life of that MSD component does not decrease.
[0063] The drying apparatus 40 is a device for dehumidifying MSD parts that have been exposed to the atmosphere and absorbed moisture, for reuse. The drying apparatus 40 has a heating and drying function for baking to remove moisture contained in the MSD parts that have been exposed to the atmosphere. The remaining floor life of the MSD parts that have been baked by the drying apparatus 40 is reset to, for example, the initial value (= floor life). Note that there may be an upper limit on the number of times baking is possible.
[0064] The display device 50 is a device for displaying information regarding the management of remaining parts to the worker. The display device 50 is, for example, a liquid crystal display device, but is not limited to that, and may be any display device.
[0065] Here, the management method of remaining parts displayed by the display device 50 will be explained with reference to Figure 5. Figure 5 is a diagram showing an example of the display of the management method according to this embodiment. Figure 5 shows the display screen displayed by the display device 50. The display screen shown in Figure 5 is displayed by the display device 50, for example, after the current production has finished, but it may also be displayed during production.
[0066] As shown in Figure 5, the information displayed on the display device 50 includes the part ID, the management method for the next production run, the status of the part, and the remaining floor life time.
[0067] The management method for the next production run indicates how remaining parts will be managed.
[0068] "To be used in the next production run" means that the MSD part will continue to be used in the next production run. If the remaining floor life is longer than the time until the next production run is completed, and the MSD part will be used in the next production run, it may be determined to be "To be used in the next production run."
[0069] "Exceeding the limit time during production" means that if the MSD component is used in the next production run, the remaining floor life will reach 0 during production, meaning it will no longer be usable in production. If the remaining floor life is shorter than the time until the next production run is completed, and the MSD component is used in the next production run, it may be determined that "the limit time during production has been exceeded." Exceeding the limit time means that the cumulative exposure time to the atmosphere exceeds the floor life.
[0070] "Baking" means performing a baking process in the drying unit 40 to return the remaining floor life to its initial value. If the remaining floor life is less than or equal to a predetermined time and the MSD part is not to be used in the next production run, it may be determined that the part is being "baked".
[0071] "Storage" means storing the MSD part in storage 30. If the remaining floor life is longer than a predetermined time and the MSD part will not be used in the next production run, it may be determined to be in "storage". For example, if the remaining floor life is long, but the number of MSD parts in the container does not meet the number required for the next production run, it will be stored in storage 30.
[0072] The component status indicates the relationship to the MSD component's current floor life (for example, at the end of production).
[0073] The remaining floor life indicates the remaining floor life at the current point in time (for example, at the end of production).
[0074] In the example in Figure 5, the management status for four MSD parts with part IDs "011" to "014" is displayed. For part ID "011", the management status for the next production run is "To be used in the next production run", the part status is "Plenty of room left before floor life", and the remaining floor life is "38H". For part ID "012", the management status for the next production run is "Critical time exceeded during production", the part status is "Approaching floor life", and the remaining floor life is "4H".
[0075] Part ID "013" will be in "baking" mode for the next production run, its condition will be "close to floor life", and its remaining floor life will be "0H". Part ID "014" will be in "storage" mode for the next production run, its condition will be "plenty of floor life remaining", and its remaining floor life will be "21H".
[0076] The parts management system 1 may also include a device that, instead of the display device 50, or together with the display device 50, provides the operator with information regarding the management of remaining parts using sound, light, or the like.
[0077] Referring again to Figure 1, the information terminal 60 is a terminal device held by workers, etc., in the space where the component mounting line 10 is located (factory space). The information terminal 60 is, for example, a portable terminal such as a tablet terminal or a smartphone, but it may also be a stationary terminal. The information terminal 60 has the function of presenting information to the worker (for example, displaying it) and the function of receiving operations from the worker.
[0078] The display unit of the information terminal 60 may also function as the display device 50. The display unit of the information terminal 60 may display the screen shown in Figure 5.
[0079] [2. Parts Management System Operation] Next, the operation of the parts management system 1 configured as described above will be explained with reference to Figure 6. Figure 6 is a flowchart showing the operation (parts management method) of the management device 20 according to this embodiment.
[0080] As shown in Figure 6, the decision unit 22 determines whether the current production (first production) is complete or not (S11). The decision unit 22 may determine that production is complete when the number of circuit boards specified in the production plan information T1 has been produced, or it may determine that production is complete when it receives an operation indicating that production is complete from the worker via an input unit or the like. The input unit may be, for example, a button or keyboard provided by the management device 20, but it may also be a device that accepts input by voice or the like. The reason for determining whether production is complete or not is that production may not be completed within the production time specified in the production plan due to the component mounting line 10 stopping or delays due to production errors, etc., and the decision unit 22 may determine that production is complete within the production time specified in the production plan.
[0081] Next, the acquisition unit 21 acquires part information T3 of the MSD part (S12). The acquisition unit 21 acquires part information T3 from, for example, an external device. The cumulative exposure time and remaining floor life time included in the part information T3 acquired here are the times that reflect the production time during which the production determined to be completed in step S11 was carried out. For example, if the production determined to be completed in step S11 was delayed, the cumulative exposure time will be a larger value than if the production was not delayed. Also, for example, if the production determined to be completed in step S11 was delayed, the remaining floor life time will be a smaller value than if the production was not delayed. Suppose that in step S12, the part information T3 shown in Figure 4 is acquired.
[0082] The acquisition unit 21 outputs the acquired part information T3 to the determination unit 22.
[0083] The management device 20 measures the atmospheric exposure time of the MSD parts, including the production time required for production, and may also obtain the part information T3 after production is completed by updating the cumulative exposure time and remaining floor life of the part information T3 stored in the storage unit 23.
[0084] Next, the acquisition unit 21 acquires production plan information T1, which includes the next production plan (S13). In step S13, assume that the production plan information T1 shown in Figure 2 has been acquired. The acquisition unit 21 outputs the acquired production plan information T1 to the determination unit 22.
[0085] Next, the decision unit 22 determines whether or not to use the remaining parts in the next production based on the production plan information T1 and the mounting data T2 (S14). Based on the production plan information T1, the decision unit 22 obtains the names of the boards to be used in the next production (in the example in Figure 2, "A" and "B"), and determines whether or not to use the remaining parts in the obtained board names based on the part IDs in the mounting data T2.
[0086] Next, if the decision unit 22 determines that the remaining parts will be used in the next production run (Yes in S14), it determines whether the remaining floor life is longer than the scheduled end time (S15). The decision unit 22 obtains the remaining floor life from the parts information T3 and the scheduled end time from the end date and time in the production plan information T1. The scheduled end time is an example of production time.
[0087] Here, the scheduled end time refers to the time between the current time and the scheduled end time. If the current time is 8:00, the start time is 9:00, and the end time is 9:50, the scheduled end time is 50 minutes. Furthermore, if the container is held in the component mounting equipment between 8:00 and 9:00, the scheduled end time also includes the waiting time from 8:00 to 9:00. The waiting time is the time when no production is taking place and the equipment is exposed to the atmosphere (for example, the time waiting to start production).
[0088] If the decision unit 22 determines that the remaining floor life is greater than the scheduled end time (Yes in S15), it determines that the part can be used in the next production (S16) and notifies the worker via the output unit 24 that it will be used in the next production (S17). For example, the decision unit 22 notifies the worker of the management mode for the next production, the status of the part, and the remaining floor life for the part ID "011" shown in Figure 5. As a result, the decision unit 22 determines to continue using the remaining part in the next production if it predicts that the remaining floor life will not reach zero at the completion of the next production (i.e., the floor life will not run out) even if the remaining part is used in the next production. This eliminates the need to replace parts, and is expected to improve productivity.
[0089] Furthermore, if the decision unit 22 determines that the remaining floor life is less than or equal to the scheduled end time (No in S15), it notifies the worker via the output unit 24 that the remaining floor life is less than or equal to the scheduled end time (for example, that the MSD part cannot be used in the next production) (S22). For example, the decision unit 22 notifies the worker of the management mode for the next production, the status of the part, and the remaining floor life corresponding to the part ID "012" shown in Figure 5. In this way, the decision unit 22 can inform the worker that if the remaining part is used in the next production, the floor life will run out during production.
[0090] Next, the decision unit 22 issues a storage instruction to the drying device 40 (S23). The decision unit 22 notifies the operator that the remaining parts will be baked in the drying device 40. Then, the decision unit 22 issues a replacement instruction for parts whose remaining floor life is longer than the scheduled end time (S24). The decision unit 22 notifies the operator that the container holding the remaining parts will be removed from the production device (e.g., the parts mounting device) in order to bake them in the drying device 40, and that the container stored in the storage unit 30 will be attached to the production device (i.e., the MSD parts will be replaced).
[0091] Note that the process in step S23 is not required. If the result in step S15 is determined to be No, the remaining parts may be stored in the storage unit 30 without being baked.
[0092] Furthermore, if the decision unit 22 determines that the remaining parts will not be used in the next production run (No in S14), it notifies the operator via the output unit 24 that the remaining parts will not be used in the next production run (S18).
[0093] Next, the determination unit 22 determines whether the remaining floor life of the remaining parts is greater than a predetermined time (S19). The predetermined time is the time used to determine whether or not to perform baking on the remaining parts in the drying device 40, and is set in advance and stored in the storage unit 23. The predetermined time may be, for example, a time corresponding to the floor life.
[0094] Next, the decision unit 22 issues a storage instruction to the dry box (S20) if the remaining floor life of the remaining parts is greater than a predetermined time (Yes in S19). For example, if the remaining floor life of the remaining parts is greater than a predetermined time, the decision unit 22 notifies the worker to store them in the storage cabinet 30. Also, if the remaining floor life of the remaining parts is less than or equal to a predetermined time (No in S19), the decision unit 22 issues a storage instruction to the drying device 40 (S21). For example, if the remaining floor life of the remaining parts is less than or equal to a predetermined time, the decision unit 22 notifies the worker to bake the remaining parts in the drying device 40.
[0095] Thus, the decision unit 22, for example, based on the production plan information T1, determines that if the MSD part is to be used in the next production, it will be used in the next production if the remaining floor life is greater than the scheduled end time, and determines to notify the worker if the remaining floor life is less than or equal to the scheduled end time. Also, the decision unit 22, for example, based on the production plan information T1, determines that if the MSD part is not to be used in the next production, it will be stored in the dry box (storage unit 30) if the remaining floor life is greater than the scheduled end time, and determines to be stored in the drying device 40 if the remaining floor life is less than or equal to the scheduled end time.
[0096] [3. Effects, etc.] As described above, the management device 20 (an example of a parts management device) according to this embodiment is a parts management device for managing the use of MSD parts that require humidity control (an example of humidity-controlled parts), and comprises an acquisition unit 21 that acquires production plan information T1 and floor life remaining time information including the remaining floor life time of the MSD parts (an example of remaining floor life time) at the time of completion of the current production (an example of a first production) that uses the MSD parts, and a determination unit 22 that determines the management method of the MSD parts after the completion of the current production based on the production plan information T1 and the remaining floor life time.
[0097] As a result, the management device 20 obtains the remaining floor life at the time of production completion, and can determine the management method for MSD parts after production completion according to the remaining floor life. Therefore, the management device 20 can determine the management method for any MSD parts remaining after production completion.
[0098] Furthermore, the production plan information T1 includes the estimated completion time (an example of production time) until the next production (an example of a second production) following the current production is completed, and the determination unit 22 further determines the management method for MSD parts based on the estimated completion time.
[0099] As a result, the management device 20 also takes into account the scheduled end time of the next production cycle, allowing it to more accurately determine, for example, whether the MSD part can be used for the next production cycle. Therefore, the management device 20 can more accurately determine how to manage any remaining MSD parts after production is complete.
[0100] Furthermore, the management methods include using the MSD parts in the next production run, notifying the workers that the MSD parts cannot be used in the next production run, storing the MSD parts in a dry box (storage room 30), or storing the MSD parts in a drying device 40.
[0101] This allows the management device 20 to determine a management method appropriate to the status of the MSD part, from among using it in the next production, notifying the worker, storing it in a dry box, and storing it in a drying device.
[0102] Furthermore, the decision unit 22 determines that the MSD part will be used in the second production if the remaining floor life is greater than the scheduled end time (Yes in S15) (S16), and determines that the worker will be notified if the remaining floor life is less than or equal to the scheduled end time (No in S15) (S22).
[0103] This allows the management device 20 to determine a management method for MSD parts according to their remaining floor life when the MSD parts are to be used in the next production run.
[0104] Furthermore, the decision unit 22 determines that if the MSD parts will not be used in the second production (No in S14) and the remaining floor life is greater than the scheduled end time (Yes in S19), they should be stored in the dry box (S20). If the remaining floor life is less than or equal to the scheduled end time (No in S19), they should be stored in the drying apparatus 40 (S21).
[0105] This allows the management device 20 to determine a management method for MSD parts according to their remaining floor life if the MSD parts are not to be used in the next production run.
[0106] Furthermore, the acquisition unit 21 acquires floor life remaining time information after the completion of production for the first production.
[0107] As a result, the management device 20 can obtain a more accurate remaining floor life time, and thus determine the management method with greater precision.
[0108] Furthermore, as described above, the parts management method according to this embodiment is a parts management method executed by a management device 20 (an example of a parts management device) that manages the use of MSD parts that require humidity control, and acquires production plan information T1 and floor life remaining time information (for example, parts information T3) including the remaining floor life of the MSD parts at the time of completion of the current production that uses the MSD parts (S12 and S13), and determines the management method of the MSD parts after the completion of the current production based on the production plan information T1 and the remaining floor life (S14 to S21).
[0109] This will produce the same effect as the control device 20 described above.
