Mode for Carrying Out the Invention

[0010] 1. Embodiment FIG. 1 shows an example of production equipment to which a member management device 80 is applied. The production equipment shown in FIG. 1 includes a substrate processing line 10L, a loading section 20, and a storage device 70. Further, the storage device 70 includes a storage vault 30, a shelf 40, a dry box 50, and an oven 60.

[0011] 1-1. Substrate processing line 10L In the substrate processing line 10L, a substrate processing machine 10 performs a predetermined substrate processing on a substrate 90. The type and number of the substrate processing machines 10 are not limited. As shown in FIG. 1, the substrate processing line 10L of the present embodiment includes a plurality (five) of substrate processing machines 10, namely, a printer 10a, a print inspection machine 10b, a component mounting machine 10c, a reflow furnace 10d, and an appearance inspection machine 10e. The substrate 90 is conveyed in the above order by a substrate conveying device.

[0012] The printer 10a prints solder at the mounting position of the component 91 on the substrate 90. The print inspection machine 10b inspects the printing state of the solder printed by the printer 10a. The component mounting machine 10c mounts a plurality of components 91 on the substrate 90 on which the solder has been printed. The component mounting machine 10c may be one or a plurality. When a plurality of component mounting machines 10c are provided, the plurality of component mounting machines 10c can share the mounting of a plurality of components 91 on the substrate 90.

[0013] The component mounting machine 10c is equipped with a component supply device that supplies components 91 to be mounted on the substrate 90. The component supply device can supply the components 91 using, for example, a feeder 22a equipped with a reel 21a shown in FIG. 2A, a tray pallet 22b equipped with a tray 21b shown in FIG. 2B, and the like. The reel 21a has a carrier tape 21t that houses the components 91 wound around the main body portion 21a1. The feeder 22a rotatably holds the reel 21a. The leading end of the carrier tape 21t is pulled out to a component extraction portion provided in the feeder 22a, and the components 91 are sequentially supplied. The reel 21a can supply relatively small components 91 such as chip components, for example.

[0014] The components 91 are arranged on the tray 21b. The tray 21b can supply relatively large components 91 such as QFP (Quad Flat Package) and BGA (Ball Grid Array), for example. The tray 21b supplies the components 91 while being equipped on the tray pallet 22b. The reflow furnace 10d heats the substrate 90 on which the components 91 have been mounted by the component mounting machine 10c, melts the solder, and performs soldering. The appearance inspection machine 10e inspects the mounting state of the components 91 mounted by the component mounting machine 10c.

[0015] In this way, the substrate processing line 10L can produce substrate products by sequentially transporting the substrate 90 using a plurality (five) of substrate processing machines 10 and executing production processes including inspection processes. Note that the substrate processing line 10L can also be equipped with substrate processing machines 10 such as a function inspection machine, a buffer device, a substrate supply device, a substrate inversion device, a shield mounting device, an adhesive application device, and an ultraviolet irradiation device as needed.

[0016] The plurality (five) of substrate processing machines 10 and the management device 19 that constitute the substrate processing line 10L are provided so as to be able to communicate with each other by a wired or wireless communication unit. The management device 19 controls the plurality (five) of substrate processing machines 10 of the substrate processing line 10L and monitors the operating status of the substrate processing line 10L. Various control data for controlling the plurality (five) of substrate processing machines 10 are stored in the management device 19. The management device 19 transmits the control data to each of the plurality (five) of substrate processing machines 10. Also, each of the plurality (five) of substrate processing machines 10 transmits the operating status and production status to the management device 19.

[0017] 1-2. Loading section 20 For example, when the reel 21a arrives at the loading section 20, the following loading operation is performed. Then, the reel 21a is, for example, housed in a storage case, mounted on a transport vehicle, and transported to the storage 30. After the reel 21a is stored in the storage 30, it is supplied to the substrate processing line 10L as necessary.

[0018] As shown in FIG. 2A, an identification code 23a that can identify the reel 21a is attached to the reel 21a. As the identification code 23a, for example, a seal printed with a one-dimensional code, a two-dimensional code, etc., a wireless tag, or the like is used. Specifically, when the reel 21a arrives at the loading section 20, the operator issues identification information using, for example, an article management device. Also, the operator reads a barcode or the like attached to the reel 21a by the supplier (vendor) using a barcode reader or the like. Then, the operator can also acquire the article information from a database in which the article information regarding the reel 21a is registered. The operator issues an identification code 23a including at least the identification information among the identification information and the article information using the article management device.

[0019] The operator attaches a seal with an identification code 23a including at least identification information to the surface of the reel 21a or the like, and houses the reel 21a in a storage case. The operator mounts the storage case containing the reel 21a on a transport vehicle. For example, the transport vehicle can be towed by the operator. Also, an automated guided vehicle capable of autonomous driving can be used as the transport vehicle. Note that the transport vehicle can also transport the reel 21a to the storage 30 without using the storage case. Also, the operator can transport the reel 21a to the storage 30 without using the transport vehicle.

[0020] Similar to the reel 21a, the operator can attach an identification code 23b that can identify the tray 21b to the tray 21b. As shown in FIG. 2B, the tray 21b is housed in a packaging bag, and the identification code 23b is attached to the packaging bag. The identification code 23b can also be attached to the tray 21b. As the identification code 23b, for example, a seal printed with a one-dimensional code, a two-dimensional code, or the like, a wireless tag, or the like is used. The transport vehicle or the operator transports the tray 21b to the storage 30 in the same manner as the reel 21a.

[0021] As shown in FIG. 2A, an identification code 24a that can identify the feeder 22a is attached to the feeder 22a. As shown in FIG. 2B, an identification code 24b that can identify the tray pallet 22b is attached to the tray pallet 22b. As the identification codes 23a and 24b, for example, a seal printed with a one-dimensional code, a two-dimensional code, or the like, a wireless tag, or the like can be used. Also, at least a part of the operations performed by the operator described above can be automated using a transport device (for example, a belt conveyor or the like), an actuator (for example, a robot arm or the like), an article management device, or the like.

[0022] 1-3. Storage 30 The storage compartment 30 can store the first member 21 that houses components 91 mounted on a substrate 90 such as a reel 21a or a tray 21b. The storage compartment 30 can also store the second member 22 used together with the first member 21 such as a feeder 22a or a tray pallet 22b. The storage compartment 30 can store both the first member 21 and the second member 22. Thus, the storage compartment 30 only needs to be able to store at least one of the first member 21 and the second member 22 and can take various forms. As shown in FIGS. 3A and 3B, the storage compartment 30 of the present embodiment is formed, for example, in an octagonal prism shape.

[0023] The storage compartment 30 includes an inlet 30a, an outlet 30b, a reading device 31, a control device 32, a display device 33, a storage unit 34, and an actuator 35. At least one of the first member 21 and the second member 22 is stored in the storage compartment 30 through the inlet 30a and taken out through the outlet 30b. In the present embodiment, the inlet 30a and the outlet 30b are provided in a common opening. The inlet 30a and the outlet 30b can also be provided in different openings.

[0024] The reading device 31 is provided above a work space 34a close to the opening of the inlet 30a. When at least one of the first member 21 and the second member 22 is stored in the storage compartment 30, the reading device 31 reads the identification code attached to the member being stored and obtains identification information for identifying the member being stored. The reading device 31 can use a known reading device (for example, a code reader that reads a one-dimensional code or a two-dimensional code). When the identification code is a wireless tag, the storage compartment 30 can be provided with a wireless device capable of wireless communication with the identification code.

[0025] The control device 32 includes a known arithmetic device and a storage device, and is configured with a control circuit. Further, the control device 32 is communicably connected to the reading device 31, the display device 33, and the actuator 35, and can control these. For example, the control device 32 can control the reading device 31. Also, the control device 32 can acquire the identification information acquired by the reading device 31 from the reading device 31.

[0026] Furthermore, the control device 32 is communicably connected to the management device 19 shown in FIG. 1. For example, the management device 19 notifies the control device 32 of the occurrence of a setup change in the substrate processing line 10L. The management device 19 can also notify the control device 32 of the occurrence of a shortage of at least one of the first member 21 and the second member 22 supplied to the substrate processing line 10L. The management device 19 can also notify the control device 32 of the possibility of a setup change occurring within a predetermined period. The management device 19 can also notify the control device 32 of the possibility of at least one of the first member 21 and the second member 22 being insufficient within a predetermined period. Based on these notifications, the control device 32 releases the necessary members.

[0027] The display device 33 can use a known display device and visually displays various information for the operator. The display device 33 displays, for example, member information indicating information about the members stored in the storage unit 34 according to the operator's operation. The member information can include, for example, the type, model, inventory quantity, etc. of the members. Also, the member information of the first member 21 can include the type, model, vendor name, remaining quantity, humidity management level, expiration date, etc. of the parts 91 accommodated in the first member 21.

[0028] Note that the display device 33 of this embodiment is configured by a touch panel, and the display device 33 also functions as an input device that receives various operations by the operator. For example, the operator can use the touch panel (display device 33 functioning as an input device) to specify a desired member to be released from the storage 30. In this case, the control device 32 releases the specified member.

[0029] The storage unit 34 only needs to be able to store at least one of the first member 21 and the second member 22, and can take various forms. As shown in FIG. 3B, the storage unit 34 of the present embodiment includes a plurality of storage units 34b, and the plurality of storage units 34b are arranged in a circular shape in a vertical direction (Z-axis direction) view. As shown in FIG. 3C, the storage unit 34b includes, for example, two types of storage spaces, a storage space 34b1 and a storage space 34b2.

[0030] A plurality of storage spaces 34b1 and 34b2 can be provided along the vertical direction (Z-axis direction). The size (width, depth, and height) of the storage space 34b1 is set to be able to store the first member 21. The size (width, depth, and height) of the storage space 34b2 is set to be able to store the second member 22 or the second member 22 equipped with the first member 21.

[0031] The actuator 35 is provided inside the plurality of storage units 34b in a vertical direction (Z-axis direction) view, and grips and moves at least one of the first member 21 and the second member 22. The actuator 35 only needs to be able to grip and move the above-mentioned member, and can take various forms. For example, a robot arm (multi-joint robot) or the like can be used as the actuator 35.

[0032] When at least one of the first member 21 and the second member 22 is received, the actuator 35 has the gripping portion grip the member carried into the work space 34a from the receiving port 30a. The actuator 35 moves the gripping portion holding the member to a predetermined storage space and releases the gripping of the member by the gripping portion. Thereby, the member is stored in the storage space. Further, when at least one of the first member 21 and the second member 22 is shipped, the actuator 35 has the gripping portion grip the member stored in the storage space. The actuator 35 moves the gripping portion holding the member to the work space 34a and releases the gripping of the member by the gripping portion. Thereby, the member can be carried out.

[0033] 1-4. Shelf 40, Dry Box 50 and Oven 60 The shelf 40 can place at least one of the first member 21 and the second member 22. Unlike the storage 30, the shelf 40 is not sealed and stores at least one of the first member 21 and the second member 22 at the ambient temperature and humidity in the room of the production equipment. The shelf 40 can be provided with a storage space similar to the storage portion 34 of the storage 30. The arrangement of the storage space is not limited and can take various forms.

[0034] Further, for example, the component 91 accommodated in the first member 21 includes a component sealed with resin. When the component that has been exposed to the atmosphere for a time exceeding the specified time and has absorbed moisture in the atmosphere is heated in the reflow furnace 10d shown in FIG. 1, the moisture contained in the component may vaporize and expand in volume, causing damage. Such a highly moisture-sensitive component 91 is called an MSL (Moisture Sensitivity Level) component, and the limit time (the maximum time available for production) that can be exposed to the atmosphere is specified for each component type.

[0035] The dry box 50 is provided with a humidity control unit that maintains a constant humidity level inside the box, and at least one of the first member 21 and the second member 22 can be stored at a constant humidity. The dry box 50 can store members at the humidity management level defined for MSL components. Therefore, when the component 91 housed in the first member 21 is an MSL component, storing the first member 21 in the dry box 50 can stop the reduction of the remaining time (flower life) during which the component 91 can be used in production.

[0036] Note that when an MSL component exceeds the limit time during which it can be exposed to the atmosphere, it can recover the limit time (the maximum time during which it can be used in production) during which it can be exposed to the atmosphere by being dried at a predetermined temperature for a predetermined time. The predetermined temperature, the predetermined time, and the number of times of drying are defined for each humidity management level of the MSL component.

[0037] The oven 60 is provided with a drying unit that dries and maintains the inside of the box at a predetermined humidity, and at least one of the first member 21 and the second member 22 can be dried to the predetermined humidity and stored at the predetermined humidity. The oven 60 can dry and store members under the conditions defined for MSL components. Therefore, when the component 91 housed in the first member 21 is an MSL component, storing the first member 21 in the oven 60 can recover the limit time (the maximum time during which it can be used in production) during which it can be exposed to the atmosphere.

[0038] 1-5. Member management device 80 The member management device 80 manages the locations of the first member 21 and the second member 22. As shown in FIG. 1, the production facility includes a warehouse area ZA1, a picking area ZA2, and an outer setup area ZA3. The warehouse area ZA1 is an area for storing at least one of the first member 21 and the second member 22 for a longer period compared to the picking area ZA2, and includes at least one (one in the figure) storage vault 30.

[0039] The picking area ZA2 is an area for temporarily storing the above members, and is provided with at least one (two in the figure) shelf 40. The above members stored in the storage 30 in the warehouse area ZA1 are conveyed to at least one of the picking area ZA2 and the external setup area ZA3. The external setup area ZA3 is provided with at least one (one in the figure) shelf 40, at least one (one in the figure) dry box 50, and at least one (one in the figure) oven 60. In the external setup area ZA3, at least one of the first member 21 and the second member 22 conveyed from at least one of the warehouse area ZA1 and the picking area ZA2 can be stored in the shelf 40, the dry box 50, or the oven 60.

[0040] Also, in the external setup area ZA3, a supply preparation operation is performed to combine the first member 21 and the second member 22 so as to be supplyable to the substrate processing line 10L. For example, when the first member 21 is a reel 21a and the second member 22 is a feeder 22a, the operator installs the reel 21a on the feeder 22a. At this time, the operator reads the identification code 23a attached to the reel 21a using, for example, a code reader of a portable terminal. Also, the operator reads the identification code 24a attached to the feeder 22a using a code reader of a portable terminal or the like.

[0041] Thereby, the identification information for identifying the reel 21a (the first identification information for identifying the first member 21) and the identification information for identifying the feeder 22a (the second identification information for identifying the second member 22) are transmitted to the member management device 80. When the member management device 80 acquires the above identification information, it generates combination information indicating the combination of the first member 21 and the second member 22. Specifically, the combination information associates the first identification information for identifying the first member 21 with the second identification information for identifying the second member 22. The member management device 80 stores the combination information in, for example, the storage device 80m shown in FIG. 4. The storage device 80m only needs to be able to store various information, and a known storage device can be used.

[0042] In addition, when at least one of the first member 21 and the second member 22 moves, the member management device 80 updates the location information of the member. For example, when the operator moves the member, the operator reads the identification code using a code reader of the mobile terminal or the like. When the mobile terminal has a positioning function, the mobile terminal transmits the location information of the member to the member management device 80 when reading the identification code. The member management device 80 updates the location information stored in the storage device 80m to the received location information.

[0043] In addition, the operator can also read the location codes provided in the warehouse area ZA1, the picking area ZA2, and the external setup area ZA3 using a code reader of the mobile terminal or the like. Thereby, the position information of the area where the read location code is provided is transmitted to the member management device 80. Also, the operator can read the location codes provided in the storage devices 70 (such as the storage vault 30, the shelf 40, the dry box 50, and the oven 60) using a code reader of the mobile terminal or the like. Thereby, the position information of the storage device 70 where the read location code is provided is transmitted to the member management device 80. Furthermore, the storage device 70 can also transmit the position information to the member management device 80.

[0044] In the external setup area ZA3, a release operation for releasing the combination of the first member 21 and the second member 22 that has become unused in the production of the substrate processing line 10L is performed as necessary. For example, when the first member 21 is the reel 21a and the second member 22 is the feeder 22a, the operator takes out the reel 21a from the feeder 22a. The taken-out reel 21a is stored in a predetermined storage device 70, and the feeder 22a is stored in a predetermined storage device 70. Also, when there is no need to release the combination, the reel 21a and the feeder 22a are stored in a predetermined storage device 70 in a combined state.

[0045] Thus, the storage device 70 may have cases where both the first member 21 and the second member 22 are stored, and cases where either the first member 21 or the second member 22 is stored. When both the first member 21 and the second member 22 are stored in the storage device 70, the combination information indicating the combination of the first member 21 and the second member 22 needs to be maintained. On the other hand, when either the first member 21 or the second member 22 is stored, the above combination information needs to be deleted. For example, when the operator deletes the above combination information, an increase in man-hours and work mistakes (such as forgetting to delete or mis-deleting) may occur.

[0046] Therefore, when either the first member 21 or the second member 22 is stored in the storage device 70, the member management device 80 of the present embodiment deletes the combination information indicating the combination of the first member 21 and the second member 22 that was used before the storage. Specifically, the member management device 80 of the present embodiment includes a determination unit 81 and a deletion unit 82. The member management device 80 may also include a setting unit 83. The member management device 80 may also include an update unit 84. As shown in FIG. 4, the member management device 80 of the present embodiment includes a determination unit 81, a deletion unit 82, a setting unit 83, and an update unit 84.

[0047] The determination unit 81, the deletion unit 82, the setting unit 83, and the update unit 84 can be provided in various control devices. For example, the determination unit 81, the deletion unit 82, the setting unit 83, and the update unit 84 can be provided in the management device 19. The determination unit 81 can also be provided in a control device of the storage device 70 (for example, the control device 32 of the storage vault 30), the control device of the portable terminal device described above, etc. The determination unit 81, the deletion unit 82, the setting unit 83, and the update unit 84 can also be formed on the cloud. As shown in FIG. 4, in the present embodiment, the determination unit 81, the deletion unit 82, the setting unit 83, and the update unit 84 are provided in the management device 19.

[0048] In addition, the member management device 80 executes control according to the flowchart shown in FIG. 5. The determination unit 81 makes a determination shown in step S12. The deletion unit 82 performs the process shown in step S13. The setting unit 83 performs the process shown in step S11. The update unit 84 performs the process shown in step S14.

[0049] 1-5-1. Determination Unit 81 The determination unit 81 determines whether the first member 21 that houses the component 91 mounted on the substrate 90 or the second member 22 used together with the first member 21 is stored in the storage device 70. The determination unit 81 may take various forms as long as it can determine whether the first member 21 or the second member 22 is stored in the storage device 70.

[0050] For example, assume a case where the first member 21 is a reel 21a, the second member 22 is a feeder 22a, and the reel 21a not equipped with the feeder 22a is stored in the storage device 70. In this case, the operator can, for example, use the code reader of the portable terminal described above to read the identification code 23a attached to the reel 21a and then store the reel 21a in the storage device 70.

[0051] In addition, for example, the storage 30 can also read the identification code 23a attached to the stored reel 21a using the reading device 31. The shelf 40, the dry box 50, or the oven 60 can be equipped with a reading device similar to the reading device 31 and can also read the identification code 23a attached to the stored reel 21a in the same manner as the storage 30. In any case, the determination unit 81 can determine the storage of the reel 21a not equipped with the feeder 22a (the storage of the first member 21) by acquiring the identification information for identifying the reel 21a (the first identification information for identifying the first member 21).

[0052] Next, assume a case where the first member 21 is the reel 21a, the second member 22 is the feeder 22a, and the feeder 22a equipped with the reel 21a is stored in the storage device 70. In this case, the operator can, for example, use a code reader of the above-described portable terminal device to read the identification code 24a attached to the feeder 22a and then store the feeder 22a equipped with the reel 21a in the storage device 70.

[0053] Also, for example, the storage 30 can use the reading device 31 to read the identification code 24a attached to the stored feeder 22a. The shelf 40, the dry box 50, or the oven 60 can be equipped with a reading device similar to the reading device 31 and can also read the identification code 24a attached to the stored feeder 22a in the same manner as the storage 30. In any case, the determination unit 81 can determine the storage of the feeder 22a equipped with the reel 21a (the storage of both the first member 21 and the second member 22) by acquiring the identification information for identifying the feeder 22a (the second identification information for identifying the second member 22).

[0054] In this way, when the determination unit 81 acquires one of the first identification information for identifying the first member 21 and the second identification information for identifying the second member 22, it can determine that the first member 21 or the second member 22 is stored in the storage device 70. Also, when the determination unit 81 acquires the other of the first identification information for identifying the first member 21 and the second identification information for identifying the second member 22, it can determine that both the first member 21 and the second member 22 are stored in the storage device 70.

[0055] The component management device 80 can include a reading device 80r that acquires first identification information by reading a first identification member 21r attached to the first component 21 and acquires second identification information by reading a second identification member 22r attached to the second component 22. Thereby, the determination unit 81 can acquire the first identification information or the second identification information using the reading device 80r. In the above example, the identification code 23a attached to the reel 21a corresponds to the first identification member 21r, and the identification code 24a attached to the feeder 22a corresponds to the second identification member 22r. Also, the code reader and the reading device 31 of the portable terminal correspond to the reading device 80r.

[0056] As described above, when the reel 21a is taken out from the feeder 22a that has become unused in the production of the substrate processing line 10L, the reel 21a or the feeder 22a may be stocked. Also, the carrier tape 21t of the reel 21a is rewound before the reel 21a is taken out from the feeder 22a. Therefore, the determination unit 81 can also determine that the reel 21a or the feeder 22a is stocked in the storage device 70 when the carrier tape 21t of the reel 21a held by the feeder 22a that has become unused in production is rewound and one of the first identification information and the second identification information is acquired.

[0057] Whether or not it is the feeder 22a that has become unused in production can be obtained from the management device 19 that manages the production of the substrate processing line 10L. Also, whether or not the carrier tape 21t has been rewound can be obtained by communication between the workbench equipped with the feeder 22a for rewinding the carrier tape 21t and the feeder 22a. The determination unit 81 can acquire these pieces of information from the management device 19 and the workbench.

[0058] The storage device 70 may take various forms as long as at least one of the first member 21 and the second member 22 can be stored. The storage device 70 of the present embodiment is a storage chamber 30 capable of storing at least one of the first member 21 and the second member 22, a shelf 40 on which the member can be placed, a dry box 50 capable of storing the member at a constant humidity, or an oven 60 capable of drying the member to a predetermined humidity and storing it at the predetermined humidity. Therefore, at least one of the first member 21 and the second member 22 can be stored in the storage chamber 30, the shelf 40, the dry box 50, or the oven 60.

[0059] Note that, as in the above example, when the determination unit 81 acquires the identification information of the member (in the above example, the reel 21a which is the first member 21) scheduled to be stored alone in the storage device 70, it can be determined that the member (the reel 21a which is the first member 21) will be stored in the storage device 70. Also, when the determination unit 81 acquires the identification information of the member (in the above example, the feeder 22a which is the second member 22) not scheduled to be stored alone, it can be determined that both the first member 21 and the second member 22 (the reel 21a and the feeder 22a) will be stored in the storage device 70. Furthermore, which of the first member 21 and the second member 22 is to be stored alone can be arbitrarily defined. The operator or the reading device 31 reads the identification code according to the regulation.

[0060] Also, the determination unit 81 can also determine the storage of the first member 21, the storage of the second member 22, or the storage of both the first member 21 and the second member 22. In this form, when the first member 21 is stored alone, the first identification information for identifying the first member 21 is acquired by the operator or the reading device 31. The determination unit 81 can determine that the first member 21 will be stored in the storage device 70 when the first identification information is acquired.

[0061] In the above-described form, when the second member 22 is stored alone, the second identification information for identifying the second member 22 is acquired by the operator or the reading device 31. When the determination unit 81 acquires the second identification information, it can determine that the second member 22 is stored in the storage device 70. Further, in the above-described form, when both the first member 21 and the second member 22 are stored, both the first identification information and the second identification information are acquired by the operator or the reading device 31. When the determination unit 81 acquires both the first identification information and the second identification information, it can determine that both the first member 21 and the second member 22 are stored in the storage device 70.

[0062] 1-5-2. Deletion unit 82 When the determination unit 81 determines that the first member 21 or the second member 22 is stored, the deletion unit 82 deletes the combination information indicating the combination of the first member 21 and the second member 22 that was used before storage (step S13 shown in FIG. 5).

[0063] As described above, the combination information associates the first identification information for identifying the first member 21 with the second identification information for identifying the second member 22. Also, in the present embodiment, the combination information is stored by the storage device 80m shown in FIG. 4. Therefore, when the determination unit 81 determines that the first member 21 or the second member 22 is stored, the deletion unit 82 deletes the combination information (association between the first identification information and the second identification information) stored in the storage device 80m.

[0064] 1-5-3. Setting unit 83 Depending on the type of the first member 21 or the second member 22, there may be a case where the operator wants to delete the combination information. Therefore, the member management device 80 of the present embodiment includes a setting unit 83. The setting unit 83 pre-sets whether to delete the combination information when the first member 21 or the second member 22 is stored in the storage device 70 (step S11 shown in FIG. 5). The setting by the setting unit 83 can be stored, for example, in the storage device 80m shown in FIG. 4.

[0065] FIG. 6 shows a setting example by the setting unit 83. The setting item No. 1 shows the case where the reel 21a not equipped on the feeder 22a is stored in the storage 30. The setting example in this case is deletion, indicating that the deletion unit 82 deletes the combination information. The setting item No. 2 shows the case where the tray 21b not equipped on the tray pallet 22b is stored in the storage 30. The setting example in this case is deletion, indicating that the combination information is deleted.

[0066] Regarding the setting items No. 3 and subsequent, the same settings are made. Also, for the second member 22 not equipped with the first member 21, the same settings can be made. In this way, the setting unit 83 can set whether to delete the combination information for each combination of a plurality of types of first members 21 and a plurality of types of storage devices 70. Also, the setting unit 83 can set whether to delete the combination information for each combination of a plurality of types of second members 22 and a plurality of types of storage devices 70.

[0067] In the form where the member management device 80 includes the setting unit 83, the determination unit 81 determines whether a predetermined member (first member 21 or second member 22) preset by the setting unit 83 is stored in a predetermined storage device 70 (step S12 shown in FIG. 5). Also, the deletion unit 82 deletes the combination information for the first member 21 or the second member 22 for which the combination information is set to be deleted by the setting unit 83 (step S13).

[0068] For example, assume that a reel 21a not equipped with a feeder 22a is stored in a storage 30. In this case, the determination unit 81 determines that a predetermined member (reel 21a) preset by the setting unit 83 is stored in a predetermined storage device 70 (storage 30) (when Yes in step S12). According to the setting No. 1, when a reel 21a not equipped with a feeder 22a is stored in the storage 30, deletion of combination information is set. Therefore, the deletion unit 82 deletes the combination information of the first identification information for identifying the above reel 21a and the second identification information for identifying the above feeder 22a (step S13).

[0069] 1-5-4. Update unit 84 When the first member 21 or the second member 22 is stored in the storage device 70, the update unit 84 updates the location information indicating the location of the stored first member 21 or second member 22 (step S14 shown in FIG. 5). As described above, the location information is stored, for example, in the storage device 80m shown in FIG. 4.

[0070] FIG. 7 shows an example of the location information. The location information shown in the figure includes identification information, storage date and time, withdrawal date and time, area, storage location, and storage information. The identification information is information for identifying the stored first member 21 or second member 22. As described above, the identification information for identifying the first member 21 is the first identification information, and the identification information for identifying the second member 22 is the second identification information. The storage date and time is the date and time when the first member 21 or the second member 22 is stored in the storage device 70. The withdrawal date and time is the date and time when the first member 21 or the second member 22 is withdrawn from the storage device 70.

[0071] The area is the area where the storage device 70 is arranged. As described above, in the production facility of the present embodiment, the area is the warehouse area ZA1, the picking area ZA2, or the external setup area ZA3. The storage location is the location where the first member 21 or the second member 22 stored in the storage device 70 is stored. The storage location can be specified by the position of the storage device 70, the storage space of the storage device 70 (for example, the storage space 34b1 or the storage space 34b2 of the storage warehouse 30). The storage information is information indicating the storage state of the first member 21 or the second member 22 in the storage device 70. At least the humidity among the ambient temperature and humidity in the storage device 70 is included in the storage information.

[0072] For example, the member (the first member 21 or the second member 22) indicated by the identification information ID1 of number 1 indicates that it was stored at the date and time DT11 and shipped out at the date and time DT21. Also, the said member indicates that it was stored in the storage location SL1 of the area AR11 in the state indicated by the storage information IF1. What has been described above for the member of number 1 also applies to the members numbered 2 and later.

[0073] Thus, in the present embodiment, the location information includes at least the storage location and the identification information among the storage date and time, the area, the storage location, and the identification information. Therefore, when the first member 21 or the second member 22 is stored in the storage device 70, the update unit 84 can update at least the storage location among the storage date and time, the area, and the storage location of the stored first member 21 or second member 22.

[0074] 2. Others In the embodiment, mainly, the case where the first member 21 is the reel 21a and the second member 22 is the feeder 22a is described. However, the first member 21 and the second member 22 are not limited thereto. For example, the first member 21 may be the tray 21b and the second member 22 may be the tray pallet 22b. Also, the first member 21 may be a wafer component and the second member 22 may be a holding member that holds the wafer component. Further, the first member 21 may be a stick component and the second member 22 may be a holding member that holds the stick component. Also, the first member 21 may be a part (cut end) of the carrier tape 21t and the second member 22 may be a container that houses a part (cut end) of the carrier tape 21t.

[0075] 3. Component management method What has been described above about the component management device 80 also applies to the component management method. Specifically, the component management method includes a determination step and a deletion step. The control performed by the determination unit 81 corresponds to the determination step. The control performed by the deletion unit 82 corresponds to the deletion step. The component management method may also include a setting step. The control performed by the setting unit 83 corresponds to the setting step. The component management method may also include an update step. The control performed by the update unit 84 corresponds to the update step.

[0076] 4. An example of the effects of the embodiment According to the component management device 80, the determination unit 81 and the deletion unit 82 are provided. Thereby, when the first member 21 or the second member 22 is stored in the storage device 70, the component management device 80 can delete the combination information indicating the combination of the first member 21 and the second member 22 that was used before storage. What has been described above about the component management device 80 also applies to the component management method.
