Description
TECHNICAL FIELD

The present description discloses a technique related to a component notification device, a feeder rack, and a component notification method.


BACKGROUND ART

The electronic component mounting system described in Patent Literature 1 includes an exposure time management section, a mounting line control section, and a check-in processing section. The exposure time management section measures the exposure time during which a humidity management target component is exposed to the atmosphere for each reel, and records the cumulative exposure time. The mounting line control section compares the exposure time limit set for the humidity management target component with the exposure time, specifies the electronic component mounting device equipped with the reel of the humidity management target component exceeding the exposure time limit based on the location information, and stops the operation by the electronic component mounting device.


The check-in processing section performs check-in processing when an electronic component stored in a component storage area is loaded. Specifically, the check-in processing section determines whether the electronic component to be loaded is a humidity management target component, and determines whether the exposure time limit is exceeded when the electronic component to be loaded is a humidity management target component. Then, when the exposure time limit has already been exceeded, the check-in processing section notifies that the electronic component cannot be used as it is in production.

DESCRIPTION OF EMBODIMENTS
1. Embodiments


FIG. 1 illustrates an example of a production facility to which component notification device 80 is applied. The production facility illustrated in FIG. 1 includes board work line 10L, loading section 20, storage cabinet 30, feeder rack 40, desiccator 50a, oven 50b, component supply device 60, work table 10t, and component management device 70.


1-1. Board Work Line 10L

In board work line 10L, board work machine 10 performs predetermined board work on board 90. The type and number of board work machines 10 are not limited. As illustrated in FIG. 1, board work line 10L of the present embodiment includes multiple (five) board work machines 10 having printer 10a, printing inspection machine 10b, component mounter 10c, reflow oven 10d, and appearance inspector 10e, and boards 90 are conveyed sequentially in this order by a board conveyance device.


Printer 10a prints solder on the mounting position of component 91 of board 90. Printing inspection machine 10b inspects the print state of solder which is printed by printer 10a. Component mounter 10c mounts multiple components 91 on board 90 on which solder is printed. One component mounter 10c may be provided, or multiple component mounters 10c may be provided. When multiple component mounters 10c are provided, multiple component mounters 10c can share the load and mount multiple components 91 on board 90.


Component mounter 10c includes component supply device 60 that supplies component 91 to be mounted on board 90. Component supply device 60 can supply components 91 by using, for example, feeder 22a equipped with reel 21a illustrated in FIG. 2A, tray pallet 22b equipped with component tray 21b illustrated in FIG. 2B, and the like. In reel 21a, component tape 21a2 accommodating component 91 is wound around main body portion 21al. Feeder 22a rotatably supports reel 21a. A distal end portion of component tape 21a2 is drawn out to a component take-out portion provided in feeder 22a so that components 91 are subsequently supplied. Reel 21a can supply relatively small components 91 such as a chip component and the like.


Components 91 are arranged in component tray 21b. Component tray 21b can supply relatively large components 91 such as a quad flat package (QFP), a ball grid array (BGA), and the like. Component tray 21b supplies component 91 in a state of being mounted on tray pallet 22b. Reflow oven 10d heats board 90 on which component 91 is mounted by component mounter 10c, melts the solder, and performs soldering. Appearance inspector 10e inspects the mounting state of component 91 mounted on board 90 by component mounter 10c.


In this way, board work line 10L may use multiple (five) board work machines 10 to convey boards 90 in order, execute production processing including inspection processing, and produce board products 900. Board work line 10L may include board work machines 10 such as a function inspector, a buffer device, a board supply device, a board reversing device, a shield mounting device, an adhesive coating device, and an ultraviolet irradiation device as needed.


Multiple (five) board work machines 10 and management device 19 constituting board work line 10L are provided to be able to communicate with each other by a wired or wireless communication section. Management device 19 controls multiple (five) board work machines 10 of board work line 10L, and monitors the operating status of board work line 10L. Management device 19 stores various control data for controlling multiple (five) board work machines 10. Management device 19 transmits the control data to each of multiple (five) board work machines 10. In addition, each of multiple (five) board work machines 10 transmits an operating status and a production status to management device 19.


1-2. Loading Section 20

For example, when reel 21a arrives at loading section 20, the following loading work is performed. Then, for example, reel 21a is accommodated in an accommodation case, mounted on a carrier, and conveyed to storage cabinet 30. After being stored in storage cabinet 30, reel 21a is supplied to board work line 10L as needed.


As illustrated in FIG. 2A, identification code 23a capable of identifying reel 21a is attached to reel 21a. As identification code 23a, for example, a seal on which a one-dimensional code, a two-dimensional code, or the like is printed, a wireless tag, or the like may be used. Specifically, when reel 21a arrives at loading section 20, the worker issues the identification information by using, for example, component management device 70 that manages component 91. Further, the worker reads the barcode or the like attached to reel 21a by the supply source (vendor) by using mobile terminal 82c such as a barcode reader and the like. Then, the worker can also acquire article information from a database in which article information related to reel 21a is registered. The worker issues identification code 23a including at least the identification information of the identification information and the article information by using component management device 70.


The worker attaches identification code 23a including at least the identification information to the surface of reel 21a or the like, and accommodates reel 21a in the accommodation case. The worker mounts the accommodation case in which reel 21a is accommodated on the carrier. For example, the carrier can be pulled by the worker. Further, the carrier may be an automated guided vehicle that can travel automatically. The carrier can convey reel 21a to storage cabinet 30 without using an accommodation case. Further, the worker can convey reel 21a to storage cabinet 30 without using a carrier.


Similarly to reel 21a, the worker can attach identification code 23b capable of identifying component tray 21b to component tray 21b. As illustrated in FIG. 2B, component tray 21b is accommodated in a packaging bag, and identification code 23b is attached to the packaging bag. Identification code 23b may be attached to component tray 21b. As identification code 23b, for example, a seal on which a one-dimensional code, a two-dimensional code, or the like is printed, a wireless tag, or the like may be used. The carrier or the worker can convey component tray 21b to storage cabinet 30 in the same manner as reel 21a.


As illustrated in FIG. 2A, identification code 24a capable of identifying feeder 22a is attached to feeder 22a. As illustrated in FIG. 2B, identification code 24b capable of identifying tray pallet 22b is attached to tray pallet 22b. As identification code 23a and identification code 24b, for example, a seal on which a one-dimensional code, a two-dimensional code, or the like is printed, a wireless tag, or the like may be used. Further, at least a part of the work performed by the worker described above can be automated by using a conveyance device (for example, a belt conveyor and the like), an actuator (for example, a robot arm and the like), component management device 70, and the like.


1-3. Storage Cabinet 30

Storage cabinet 30 may take various forms as long as storage cabinet 30 can store component container 21 accommodating component 91, such as reel 21a, component tray 21b, feeder 22a, and tray pallet 22b, to be mounted on board 90, or an accommodation case accommodating component container 21. When component container 21 is loaded from loading port 30a, storage cabinet 30 of the embodiment uses transfer device 35 to move and store component container 21 to storage section 34. Further, when component container 21 stored in storage section 34 is unloaded, storage cabinet 30 moves component container 21 stored in storage section 34 to work space 34a close to unloading port 30b by using transfer device 35 so that component container 21 can be unloaded. Similarly, storage cabinet 30 can load and unload, and store an accommodation case accommodating at least one component container 21.


As described above, storage cabinet 30 of the embodiment is an automated warehouse in which loading and unloading of component container 21 or the accommodation case is automated. Storage cabinet 30 stores component container 21 or the accommodation case, and the worker can also load and unload component container 21 or the accommodation case. As illustrated in FIGS. 3A and 3B, storage cabinet 30 of the embodiment is formed in, for example, an octagonal prism shape. Further, storage cabinet 30 of the embodiment includes loading port 30a, unloading port 30b, reading device 31, control device 32, display device 33, storage section 34, transfer device 35, humidity adjustment device 36, and temperature adjustment device 37. Component container 21 is loaded into storage cabinet 30 from loading port 30a and is unloaded from unloading port 30b. In the embodiment, loading port 30a and unloading port 30b are provided in a common opening portion. Loading port 30a and unloading port 30b may also be provided in different opening portions.


Reading device 31 is provided above work space 34a close to loading port 30a. When component container 21 is loaded into storage cabinet 30, reading device 31 reads the identification code (for example, identification code 23a or identification code 23b) attached to loaded component container 21 and acquires the identification information for identifying loaded component container 21. As reading device 31, a known reading device (for example, a code reader that reads a one-dimensional code or a two-dimensional code) may be used. When the identification code is a wireless tag, storage cabinet 30 may include a wireless device capable of wirelessly communicating with the identification code.


Control device 32 includes a well-known computing device and a storage device, and constitutes a control circuit. Further, control device 32 is communicably connected to reading device 31, display device 33, transfer device 35, humidity adjustment device 36, and temperature adjustment device 37, and can control these devices. For example, control device 32 can control reading device 31. Further, control device 32 can acquire the identification information acquired by reading device 31 from reading device 31.


Further, control device 32 is provided to communicate with management device 19, component management device 70, and the like illustrated in FIG. 1 through a wired or wireless communication section. For example, management device 19 notifies control device 32 of the occurrence of the setup change in board work line 10L. Management device 19 can also notify control device 32 of the occurrence of shortage of component container 21 supplied to board work line 10L. Management device 19 can also notify control device 32 of a possibility that a setup change occurs in a predetermined period. Management device 19 can also notify control device 32 of a possibility that the component container 21 runs short in a predetermined period. Control device 32 unloads necessary component container 21 based on the notification.


As display device 33, a well-known display device may be used, and displays various information so that the worker can visually recognize the data. Display device 33 displays, for example, member information indicating information related to component container 21 stored in storage section 34 in accordance with an operation of the worker. The member information may include, for example, the type, model, stock quantity, and the like of the member. Further, the member information may include the type, model, vendor name, quantity, humidity management level, expiration date, and the like of component 91 accommodated in component container 21.


Display device 33 of the embodiment includes a touch panel, and display device 33 also functions as an input device of receiving various operations by the worker. For example, the worker can designate desired component container 21 to be unloaded from storage cabinet 30 by using display device 33 functioning as an input device. In this case, control device 32 unloads designated component container 21.


The above description of component container 21 can be similarly applied to at least an accommodation case accommodating at least one component container 21. However, in this case, when accommodating component container 21 in the accommodation case, the worker reads the identification code attached to the accommodation case and the identification code attached to component container 21 by using the code reader or the like of mobile terminal 82c. Accordingly, the identification information for identifying the accommodation case and the identification information for identifying component container 21 are associated with each other and stored in the storage device of component management device 70.


When the accommodation case is loaded, reading device 31 reads the identification code attached to the accommodation case to acquire identification information for identifying the loaded accommodation case. Control device 32 acquires the identification information of component container 21 accommodated in the accommodation case loaded in storage cabinet 30 from the correspondence relationship of the identification information stored in the storage device of component management device 70. Accordingly, control device 32 can recognize component container 21 accommodated in the accommodation case loaded in storage cabinet 30.


Storage section 34 may take various forms as long as storage section 34 can accommodate component container 21 or the accommodation case. As illustrated in FIG. 3B, storage section 34 of the embodiment includes multiple storage units 34b, and multiple storage units 34b are arranged in a circular shape when viewed in the vertical direction (Z-axis direction). Further, as illustrated in FIG. 3C, storage unit 34b includes, for example, two types of storage spaces, storage space 34b1 and storage space 34b2.


Multiple storage spaces 34b1 and multiple storage spaces 34b2 may be provided along the vertical direction (Z-axis direction). For example, the size (width dimension, depth dimension, and height dimension) of storage space 34b1 is set to store component container 21. The size (width dimension, depth dimension, and height dimension) of storage space 34b2 is set to store an accommodation case accommodating component container 21.


Transfer device 35 is provided inside multiple storage units 34b when viewed in the vertical direction (Z-axis direction), and grips and moves component container 21 or the accommodation case. Transfer device 35 may take various forms as long as transfer device 35 can grip and move component container 21 or the accommodation case. For example, a robot arm (an articulated robot), a lifting and lowering slide mechanism, and the like may be used for transfer device 35.


In transfer device 35, a gripper grips component container 21 or the accommodation case carried into work space 34a from loading port 30a during loading. Transfer device 35 moves the gripper to a predetermined storage space and releases the gripping of component container 21 or the accommodation case by the gripper. Thus, component container 21 or the accommodation case is stored in a predetermined storage space. Further, in transfer device 35, the gripper grips component container 21 or the accommodation case accommodated in a predetermined storage space during unloading. Transfer device 35 moves the gripper to work space 34a and releases the gripping of component container 21 or the accommodation case by the gripper. Accordingly, component container 21 or the accommodation case can be carried out. The carry-in and carry-out of component container 21 or the accommodation case may be performed by the worker or may be performed by an automated guided vehicle or the like.


For example, components 91 accommodated in component container 21 include resin-sealed component 91. When the component which is exposed to the atmosphere for more than a defined time and absorbs moisture in the atmosphere is heated in reflow oven 10d illustrated in FIG. 1, the moisture contained in the component may evaporate and expand in volume, leading to damage. Such component 91 having high humidity sensitivity is referred to as a moisture sensitivity device (MSD) component, and the time during which the component can be exposed to the atmosphere for each component type (the time during which the component can be used in production) is defined.


In the present description, component 91 that is mounted on board 90 and requires humidity management is referred to as management target component 91t. Storage cabinet 30 of the embodiment includes humidity adjustment device 36. Humidity adjustment device 36 can maintain storage section 34 at a predetermined atmospheric humidity (below the predetermined humidity defined by the humidity management level of management target component 91t), and storage cabinet 30 can store management target component 91t at the predetermined atmospheric humidity. Therefore, by storing management target component 91t in storage cabinet 30, it is possible to stop the decrease in the remaining time during which management target component 91t can be used in production.


Further, storage cabinet 30 of the embodiment includes temperature adjustment device 37. Temperature adjustment device 37 can maintain storage section 34 at a predetermined atmospheric temperature (a predetermined temperature defined by the humidity management level of management target component 91t), and storage cabinet 30 can store management target component 91t at the predetermined atmospheric temperature. The atmospheric temperature in the room of the production facility is often maintained at the predetermined temperature defined by the humidity management level of management target component 91t. In this case, temperature adjustment device 37 may be omitted from storage cabinet 30.


1-4. Feeder Rack 40, Desiccator 50a, Oven 50b, Component Supply Device 60, and Work Table 10t

Feeder rack 40 is component holding unit 80u. Component holding unit 80u temporarily stores component container 21 which is unloaded from storage cabinet 30 and is not yet used for production of board product 900 or component container 21 which is no longer needed after the production of board product 900 ends. In this case, component container 21 is feeder 22a in which reel 21a around which component tape 21a2 accommodating component 91 is wound is rotatably supported.


In feeder rack 40, unlike storage cabinet 30, storage region 41 of feeder 22a is not sealed, and feeder 22a is exposed to the atmosphere. That is, feeder rack 40 can store feeder 22a at the atmospheric temperature and the atmospheric humidity in the room of the production facility. For example, as illustrated in FIG. 4, feeder rack 40 includes at least one storage region 41 (in FIG. 4, storage regions A1 to A4 are illustrated so that four storage regions 41 can be identified). Each of at least one storage region 41 (four storage regions A1 to A4) includes multiple slots 41a, and each of multiple slots 41a can hold one feeder 22a.


Further, each of at least one storage region 41 (four storage regions A1 to A4) includes storage position identification section 42. Storage position identification section 42 is assigned a slot number capable of identifying multiple slots 41a provided in one storage region 41. Storage position identification section 42 is provided at a portion of feeder rack 40 where the storage position at which feeder 22a is stored can be identified (for example, in FIG. 4, an upper portion of an insertion port through which feeder 22a is inserted into slot 41a).


Further, storage position identification section 42 is provided with indicator 82a. A light emission state (lighting, extinction, blinking, display color, and the like) of indicator 82a is controlled according to feeder 22a held in slot 41a. For example, feeder rack 40 can notify the worker of feeder 22a to be conveyed by lighting indicator 82a corresponding to slot 41a in which feeder 22a to be conveyed to the worker is held in a specific color. The arrangement and number of storage regions 41 and the accommodation form of feeder 22a are not limited, and various forms may be adopted. For example, feeder rack 40 may include storage region 41 capable of storing an accommodation case accommodating feeder 22a.


Desiccator 50a includes a humidity control section that maintains the inside of desiccator 50a at a predetermined atmospheric humidity, and can store component container 21 or the accommodation case at the predetermined atmospheric humidity. Desiccator 50a can store management target component 91t at the atmospheric humidity defined by the humidity management level of management target component 91t. Therefore, similarly to storage cabinet 30, by storing management target component 91t in desiccator 50a, it is possible to stop the decrease in the remaining time during which management target component 91t can be used in production.


When the remaining time during which management target component 91t can be used in production is exceeded, by drying at a predetermined atmospheric temperature for a predetermined time, it is possible to recover the remaining time during which management target component 91t can be used in production. The predetermined atmospheric temperature, the predetermined time, and the number of times of drying are defined for each humidity management level of management target component 91t.


Oven 50b includes a drying section that dries and maintains the inside of oven 50b to a predetermined atmospheric humidity, and can dry component container 21 or management target component 91t accommodated in the accommodation case to a predetermined humidity and store the same at the predetermined atmospheric humidity. Oven 50b can dry and store management target component 91t under the condition defined by the humidity management level of management target component 91t. Therefore, by storing management target component 91t in oven 50b, it is possible to recover the remaining time during which management target component 91t can be used in production.


Component supply device 60 supplies component 91 to be mounted on board 90. As described above, component supply device 60 can supply components 91 by using, for example, feeder 22a equipped with reel 21a illustrated in FIG. 2A, tray pallet 22b equipped with component tray 21b illustrated in FIG. 2B, and the like. As illustrated in FIG. 5, component supply device 60 of the embodiment can supply component 91 by using feeder 22a. Further, component supply device 60 illustrated in FIGS. 1 and 5 is component holding unit 80u that is detachably provided with respect to component mounter 10c.


As illustrated in FIG. 5, component supply device 60 includes at least one storage region 61 (two storage regions 61 in the upper and lower stages in FIG. 5). Each of at least one storage region 61 (two storage regions 61 in the upper and lower stages) includes multiple slots 61a, and each of multiple slots 61a can hold one feeder 22a. Further, for example, multiple slots 61a of storage region 61 in the upper stage are provided with indicator 82a similar to indicator 82a described above. Specifically, indicator 82a is provided at a portion (for example, in FIG. 5, an upper portion of feeder 22a held in slot 61a) capable of identifying a storage position where feeder 22a is stored in component supply device 60.


On work table 10t, the worker can perform various kinds of work. Specifically, work table 10t includes flat plate-shaped work space 10w on a desk. For example, the worker can place component container 21 in work space 10w and perform various kinds of work described later. Further, work table 10t is provided with indicator 82a similar to indicator 82a described above.


1-5. Component Management Device 70

Component management device 70 manages the location of component 91. Specifically, component management device 70 manages the location of component container 21 accommodating component 91. The production facility illustrated in FIG. 1 includes warehouse area ZA1, picking area ZA2, external setup area ZA3, and pre-line setup area ZA4. Compared to picking area ZA2, warehouse area ZA1 is a region in which component container 21 accommodating components 91 is stored for a long period, and includes at least one (one in FIG. 1) storage cabinet 30.


Picking area ZA2 is a region for temporarily storing component container 21 accommodating components 91, and includes at least one (one in FIG. 1) feeder rack 40. Picking area ZA2 may also include at least one (one in FIG. 1) desiccator 50a, at least one (one in FIG. 1) component supply device 60, and at least one (one in FIG. 1) work table 10t. Component container 21 stored in storage cabinet 30 of warehouse area ZA1 is conveyed to picking area ZA2. Component container 21 stored in storage cabinet 30 of warehouse area ZA1 can also be conveyed to external setup area ZA3.


In external setup area ZA3, the worker can perform various kinds of work. External setup area ZA3 includes at least one (one in FIG. 1) feeder rack 40. External setup area ZA3 may also include at least one (one in FIG. 1) desiccator 50a, at least one (one in FIG. 1) oven 50b, at least one (one in FIG. 1) component supply device 60, and at least one (one in FIG. 1) work table 10t. Component container 21 conveyed from warehouse area ZA1 or picking area ZA2 can be temporarily stored in these devices.


In external setup area ZA3, for example, supply preparation work is performed in which reel 21a and feeder 22a are combined to enable supply to board work line 10L. For example, worker mounts reel 21a on feeder 22a. At this time, the worker reads identification code 23a attached to reel 21a by using, for example, a code reader of mobile terminal 82c. Further, the worker reads identification code 24a attached to feeder 22a by using a code reader or the like of mobile terminal 82c.


Accordingly, identification information for identifying reel 21a and identification information for identifying feeder 22a are transmitted to component management device 70. When the identification information is acquired, component management device 70 stores the identification information of reel 21a and the identification information of feeder 22a in the storage device in association with each other. Further, for example, when component container 21 is moved, component management device 70 updates the location information of component container 21.


For example, when moving reel 21a, the worker reads identification code 23a by using a code reader or the like of mobile terminal 82c. When mobile terminal 82c has a positioning function, mobile terminal 82c reads the identification code 23a and transmits the location information of reel 21a to component management device 70. Component management device 70 updates the location information of reel 21a stored in the storage device to the received location information. Similarly, for example, component management device 70 can update the location information of feeder 22a when feeder 22a is moved.


When the supply preparation work ends, component container 21 is conveyed to pre-line setup area ZA4. In pre-line setup area ZA4, the worker or the conveyance device can supply component container 21 to component mounter 10c and collect component container 21 from component mounter 10c. Further, the pre-line setup area ZA4 includes at least one (one in FIG. 1) feeder rack 40. Pre-line setup area ZA4 may include at least one (one in FIG. 1) component supply device 60 and at least one (one in FIG. 1) work table 10t.


Feeder rack 40 and component supply device 60 can temporarily store feeder 22a which is not yet used for production of board product 900 or feeder 22a which is no longer needed after the production of board product 900 ends. Feeder 22a that is no longer needed after the production of board product 900 ends is conveyed to external setup area ZA3. When the time until feeder 22a is used in the production of next board product 900 is less than a predetermined time, feeder 22a is stored in picking area ZA2 or external setup area ZA3. When the time is equal to or more than the predetermined time, feeder 22a is stored in warehouse area ZA1.


Further, component management device 70 can manage the remaining time from when management target component 91t is exposed to the atmosphere to when the defined time available for production is reached. As described above, when exposed to the atmosphere, management target component 91t absorbs moisture in the atmosphere and the remaining time decreases. Therefore, component management device 70 may start to decrease the remaining time when the packaging of management target component 91t is opened in loading section 20 and predetermined work is performed. For example, the worker attaches an identification code (for example, identification code 23a attached to reel 21a) to component container 21 accommodating component 91.


Then, the worker reads the identification code attached to component container 21 by using a code reader or the like of mobile terminal 82c. Accordingly, the identification information for identifying component container 21 accommodating component 91 is transmitted to component management device 70 and stored in the storage device of component management device 70. For example, component management device 70 determines whether component 91 accommodated in component container 21 is management target component 91t by referring to a database in which information related to component 91 is stored. When component 91 is management target component 91t, component management device 70 stores information (for example, a flag) indicating that component 91 is management target component 91t, identification information, a humidity management level, and the like in the storage device, and starts to decrease the remaining time.


Further, while management target component 91t is stored in storage cabinet 30 or desiccator 50a, component management device 70 stops the decrease in the remaining time during which management target component 91t can be used in production. Further, when management target component 91t is stored in oven 50b or when the baking processing is executed in storage cabinet 30, component management device 70 resets the remaining time during which management target component 91t can be used in production (sets the remaining time to a defined time available for production), increases the number of times of drying by one time, and stores management target component 91t in the storage device.


1-6. Component Notification Device 80

Component container 21 accommodating component 91 moves in the production facility illustrated in FIG. 1. Therefore, when component container 21 is unloaded from storage cabinet 30, management target component 91t requiring humidity management may not be stored in an appropriate storage place. If management target component 91t is not stored in an appropriate storage place, the remaining time during which management target component 91t can be used for production may continue to decrease, and management target component 91t may not be used in production. Further, there is a possibility that work of recovering the remaining time during which management target component 91t can be used in production by oven 50b or the like is required.


Here, in the embodiment, component notification device 80 is provided. Component notification device 80 includes determination section 81 and notification section 82. Determination section 81 and notification section 82 can be provided in various control devices. For example, at least one of determination section 81 and notification section 82 can be provided in feeder rack 40. At least one of determination section 81 and notification section 82 may be provided in component supply device 60. At least one of determination section 81 and notification section 82 may be provided in work table 10t.


At least one of determination section 81 and notification section 82 may be provided in component supply device 60 provided in component mounter 10c. At least one of determination section 81 and notification section 82 may be provided in management device 19. At least one of determination section 81 and notification section 82 may be provided in component management device 70. At least one of determination section 81 and notification section 82 may be formed on a cloud.


As illustrated in FIG. 7, in component notification device 80 of the embodiment, both determination section 81 and notification section 82 are provided in feeder rack 40. As described above, feeder rack 40 is component holding unit 80u. Further, component notification device 80 executes a control in accordance with a flowchart illustrated in FIG. 8. Determination section 81 performs the processing and determination illustrated in step S11 and step S12. Notification section 82 performs the processing illustrated in step S13.


1-6-1. Determination Section 81

When component container 21 accommodating component 91 to be mounted on board 90 is exposed to the atmosphere, determination section 81 determines whether component 91 accommodated in component container 21 is management target component 91t requiring humidity management. Determination section 81 may take various forms as long as determination section 81 can determine whether component 91 accommodated in component container 21 is management target component 91t.


For example, as illustrated in FIG. 4, it is assumed that feeder 22a is stored in feeder rack 40. In this case, feeder 22a is exposed to the atmosphere. When feeder 22a is stored in feeder rack 40, determination section 81 can determine whether component 91 accommodated in feeder 22a is management target component 91t. Specifically, determination section 81 acquires the identification information of feeder 22a (step S11 illustrated in FIG. 8). When feeder 22a is held in slot 41a, the connector of feeder 22a is connected to the connector of feeder rack 40. Accordingly, feeder 22a is supplied with power from feeder rack 40 via the connector, and can communicate with the control device of feeder rack 40.


Determination section 81 provided in feeder rack 40 can communicate with feeder 22a to acquire the identification information of feeder 22a. Then, determination section 81 determines whether component 91 accommodated in feeder 22a is management target component 91t (step S12 illustrated in FIG. 8). As described above, the identification information of feeder 22a and the identification information of reel 21a are stored in association with each other in the storage device of component management device 70. Further, the storage device stores information related to management target component 91t.


Accordingly, determination section 81 can determine whether component 91 accommodated in feeder 22a is management target component 91t by referring to the storage device of component management device 70. Further, when component 91 accommodated in feeder 22a is management target component 91t, determination section 81 can also acquire the humidity management level, the remaining time during which management target component 91t can be used in production, and the like.


As illustrated in FIG. 5, it is assumed that feeder 22a is stored in component supply device 60. Also in this case, feeder 22a is exposed to the atmosphere. Similarly to the case of feeder rack 40, when feeder 22a is stored in component supply device 60, determination section 81 provided in component supply device 60 can determine whether component 91 accommodated in feeder 22a is management target component 91t. As described above, when component container 21 is stored in component holding unit 80u, determination section 81 can determine whether component 91 accommodated in component container 21 is management target component 91t.


As illustrated in FIG. 6, it is assumed that component container 21 is left on work table 10t. Also in this case, feeder 22a is exposed to the atmosphere. For example, a wireless tag is attached to component container 21 illustrated in FIG. 6. Work table 10t includes wireless device 10m capable of wirelessly communicating with the wireless tag. Determination section 81 provided in work table 10t can acquire the identification information of feeder 22a by wirelessly communicating with feeder 22a with wireless device 10m. Similarly to the case of feeder rack 40, when component container 21 is left on work table 10t, determination section 81 can determine whether component 91 accommodated in feeder 22a is management target component 91t. Work table 10t may include multiple directional wireless devices 10m. In this case, determination section 81 can also recognize the position where component container 21 is left on the work table 10t.


1-6-2: Notification Section 82

When determination section 81 determines that component 91 is management target component 91t, notification section 82 notifies the presence of management target component 91t through at least one of the visual, auditory, and tactile senses of the worker (step S13 illustrated in FIG. 8). Notification section 82 may take various forms as long as notification section 82 can notify of the presence of management target component 91t through at least one of the visual sense, auditory sense, and tactile sense of the worker.


When determination section 81 determines that component 91 is management target component 91t, notification section 82 can notify the worker of the presence of management target component 91t by lighting or blinking indicator 82a in a predetermined color. For example, as illustrated in FIG. 4, it is assumed that feeder 22a accommodating management target component 91t is stored in feeder rack 40. As described above, feeder rack 40 is provided with indicator 82a. Indicator 82a only needs to emit light of a predetermined color, and a known indicator such as a light emitting diode may be used.


Notification section 82 lights or blinks at least one indicator 82a in a predetermined color to notify the worker of the presence of management target component 91t. In FIG. 4, indicator 82a that is lighted or blinks in a predetermined color is represented by a black circle, and another indicator 82a is represented by a white circle. Further, for example, it is assumed that feeder 22a accommodating management target component 91t is stored in storage region A1 illustrated in FIG. 4. In this case, notification section 82 can notify the worker of the presence of management target component 91t by lighting or blinking at least one indicator 82a provided in storage region A1 in a predetermined color.


Further, indicator 82a illustrated in FIG. 4 is provided at a portion of feeder rack 40 where the storage position where feeder 22a is stored can be identified (for example, in FIG. 4, an upper portion of an insertion port where feeder 22a is inserted into slot 41a). In this case, notification section 82 can cause indicator 82a corresponding to the storage position where feeder 22a accommodating management target component 91t is stored to emit light. For example, feeder 22a held in second slot 41a from the left side of the paper surface of storage region A1 accommodates management target component 91t. In this case, notification section 82 causes indicator 82a provided at the upper portion of the insertion port of feeder 22a to emit light.


In either case, the predetermined color for causing indicator 82a to emit light may be set freely. For example, the predetermined color may be set to a color different from the color for the work instruction described above. Further, the predetermined color may be set and changed by the user of feeder rack 40. The above description of indicator 82a provided in feeder rack 40 can be similarly applied to indicator 82a provided in component supply device 60, and indicator 82a provided on work table 10t.


When determination section 81 determines that component 91 is management target component 91t, notification section 82 can output a predetermined sound from acoustic device 82b to notify the worker of the presence of management target component 91t. For example, as illustrated in FIG. 4, it is assumed that feeder 22a accommodating management target component 91t is stored in feeder rack 40. Feeder rack 40 is provided with acoustic device 82b. As acoustic device 82b, any known acoustic device such as a speaker may be used as long as the acoustic device can emit a predetermined sound. Notification section 82 outputs a predetermined sound from acoustic device 82b to notify the worker of the presence of management target component 91t.


The predetermined sound output from acoustic device 82b may be set freely. For example, the predetermined sound may be a mechanical sound such as a beep sound. The predetermined sound may be a sound of a predetermined scale such as a melody. The predetermined sound may be voice. When the predetermined sound is voice, notification section 82 easily notifies storage region 41 in which feeder 22a accommodating management target component 91t is stored, a position in storage region 41, and the like. Further, the predetermined sound can be set and changed by the user of feeder rack 40. The above description of acoustic device 82b provided in feeder rack 40 can be similarly applied to acoustic device 82b provided in component supply device 60, and acoustic device 82b provided in work table 10t.


When determination section 81 determines that component 91 is management target component 91t, notification section 82 can notify the worker of the presence of management target component 91t by using mobile terminal 82c carried by the worker. Mobile terminal 82c is not limited as long as mobile terminal 82c is a terminal carried by the worker. For example, notification section 82 can display the presence of management target component 91t on mobile terminal 82c and notify the worker of the presence of management target component 91t. Notification section 82 can display the presence of management target component 91t by, for example, characters, figures, symbols, model views, images, or moving images. Notification section 82 can also display, on mobile terminal 82c, a place where component container 21 accommodating management target component 91t is stored or left.


Notification section 82 can notify a storage region in which component container 21 accommodating management target component 91t is stored, a position in the storage region, or the like. Further, notification section 82 can also output a predetermined sound from mobile terminal 82c to notify the worker of the presence of management target component 91t. The above description of acoustic device 82b can be similarly applied to a case where a predetermined sound is output from mobile terminal 82c. Further, notification section 82 can also vibrate mobile terminal 82c to notify the worker of management target component 91t. Notification section 82 can also notify the worker of presence of management target component 91t by combining the forms described above by using mobile terminal 82c.


When determination section 81 determines that component 91 is management target component 91t, notification section 82 may cause component container 21 accommodating management target component 91t to protrude from the holding position to notify the worker of the presence of management target component 91t. For example, as illustrated in FIG. 4, it is assumed that feeder 22a accommodating management target component 91t is stored in feeder rack 40. In this case, as illustrated in FIG. 9, feeder rack 40 includes movement device 43 and trajectory member 44. Movement device 43 is provided to be able to move (travel) trajectory member 44. Trajectory member 44 is provided along the arrangement direction of slots 41a (X-axis direction in FIG. 9).


Movement device 43 includes at least one (two in FIG. 9 for convenience of illustration) holding section 43a. Holding section 43a can clamp feeder 22a. Holding section 43a is movable along the attachment/detachment direction (Y-axis direction in FIG. 9) of feeder 22a by, for example, a linear motion mechanism or the like, and can move feeder 22a along the attachment/detachment direction (Y-axis direction). Movement device 43 can move to slot 41a in which feeder 22a accommodating management target component 91t is stored, clamp feeder 22a by using holding section 43a, and move feeder 22a along the attachment/detachment direction (Y-axis direction). When movement device 43 includes the same number of holding sections 43a as multiple slots 41a provided in one storage region 41, trajectory member 44 may be omitted.


As described above, when determination section 81 determines that component 91 is management target component 91t, notification section 82 can cause feeder 22a accommodating management target component 91t to protrude from the holding position by using movement device 43 to notify the worker of the presence of the management target component 91t. In FIG. 9, a state in which feeder 22a accommodating management target component 91t protrudes from the holding position by a predetermined amount is indicated by an arrow. When the worker approaches feeder rack 40 to a predetermined distance, notification section 82 can cause feeder 22a accommodating management target component 91t to protrude from the holding position. Further, when the worker performs a predetermined operation, notification section 82 can cause feeder 22a accommodating management target component 91t to protrude from the holding position. The above description of feeder rack 40 can be similarly applied to component supply device 60.


Further, notification section 82 can employ the following notification method in any of the forms described above. In the following notification method, indicator 82a is described as an example, but the notification method can be similarly applied to acoustic device 82b, mobile terminal 82c, movement device 43, and the like. For example, as the remaining time from when management target component 91t is exposed to the atmosphere to when the defined time available for production is reached is shorter, it is necessary to store management target component 91t in an appropriate storage place within a short time, and it is necessary to alert the worker. Here, when the remaining time from when management target component 91t is exposed to the atmosphere to when the defined time available for production is reached is less than a predetermined time, notification section 82 can change a notification method of management target component 91t, compared to a case where the remaining time is equal to or more than the predetermined time.


For example, notification section 82 changes the color of lighting or blinking indicator 82a when the remaining time is less than the predetermined time, compared to a case where the remaining time is equal to or more than the predetermined time. For example, when the remaining time is less than a predetermined time, notification section 82 can light or blink indicator 82a in a color having a relatively high chroma such as red or yellow, and when the remaining time is equal to or more than the predetermined time, notification section 82 can light or blink indicator 82a in a color having a relatively low chroma such as gray. In addition, when the remaining time is less than the predetermined time, notification section 82 can shorten the blinking cycle of indicator 82a compared to a case where the remaining time is equal to or more than the predetermined time.


The predetermined time can be set freely. For example, the predetermined time may be set to zero. In this case, notification section 82 can change the notification method of management target component 91t for which the remaining time is reached the defined time available for production and for which the remaining time has elapsed, compared to the notification method of management target component 91t for which the remaining time has not elapsed. Further, when the remaining time from when management target component 91t is exposed to the atmosphere to when the defined time available for production is reached has elapsed, notification section 82 can also notify whether management target component 91t can be subjected to the baking processing. Information as to whether management target component 91t can be subjected to the baking processing is stored in, for example, the storage device of component management device 70.


As the humidity management level defined for management target component 91t becomes higher, the initial remaining time is shorter, and it is necessary to store management target component 91t in an appropriate storage place within a short time, and it is necessary to alert the worker. Here, when the humidity management level defined for management target component 91t is equal to or more than a predetermined level, notification section 82 can change the notification method of management target component 91t compared to management target component 91t having the humidity management level less than the predetermined level. For example, notification section 82 changes the predetermined color for lighting or blinking indicator 82a that notifies the presence of management target component 91t having the humidity management level equal to or more than a predetermined level, compared to indicator 82a that notifies the presence of management target component 91t having a humidity management level less than the predetermined level.


Further, when there are multiple management target components 91t having the same humidity management level, notification section 82 may light or blink multiple indicators 82a that notify of the presence of management target components 91t in the same color. Further, when there are multiple management target components 91t having the same humidity management level, notification section 82 can match the cycle of blinking multiple indicators 82a that notify of the presence of management target components 91t.


When multiple desiccators 50a capable of storing component containers 21 accommodating management target components 91t under the condition defined by the humidity management level of management target components 91t are provided, notification section 82 can notify desiccators 50a that store component containers 21 accommodating management target components 91t. For example, in the production facility illustrated in FIG. 1, picking area ZA2 includes one desiccator 50a, and external setup area ZA3 includes one desiccator 50a. Desiccator 50a may include indicator 82a similar to indicator 82a described above.


In this case, notification section 82 can light or blink indicator 82a provided in desiccator 50a that stores component container 21 accommodating management target component 91t. Further, notification section 82 can match the notification method of management target component 91t with the notification method of desiccator 50a that stores component container 21 accommodating management target component 91t. For example, notification section 82 lights or blinks indicator 82a provided in feeder rack 40 in a predetermined color, and notifies the worker of the presence of management target component 91t. Notification section 82 notifies desiccator 50a by lighting or blinking indicator 82a provided in desiccator 50a that stores feeder 22a accommodating management target component 91t in the same color as the predetermined color.


2. Feeder Rack 40 and Other Forms Thereof

Further, feeder rack 40 is component holding unit 80u that includes component notification device 80 and temporarily stores feeder 22a which is unloaded from storage cabinet 30 and is not yet used for production of board product 900 or feeder 22a which is no longer needed after the production of board product 900 ends. Component notification device 80 may be in any form described above.


Similarly, component supply device 60 is a component holding unit 80u which includes component notification device 80 and temporarily stores feeder 22a which is unloaded from storage cabinet 30 and is not yet used for production of board product 900 or feeder 22a which is no longer needed after the production of board product 900 ends. Component notification device 80 may be in any form described above. Further, component supply device 60 may be provided in component mounter 10c. Further, component container 21 may be reel 21a around which component tape 21a2 accommodating component 91 is wound. Feeder rack 40 in this case corresponds to a reel rack. In the description of the reel rack, feeder 22a in the description of feeder rack 40 is replaced with reel 21a. Further, in any of the embodiments described above, component container 21 may be component tray 21b illustrated in FIG. 2B or tray pallet 22b equipped with component tray 21b.
