DETAILED DESCRIPTION OF THE INVENTION

[0010] Hereinafter, an embodiment will be described with reference to the drawings. Fig. 1 shows an electronic component storage reel 20 according to this embodiment. The electronic component storage reel 20 includes a tape 21 on which a plurality of electronic components 10 are stored, and a reel 25 on which the tape 21 is wound. Fig. 2 shows the tape 21 on which a plurality of electronic components 10 are stored. Fig. 3 shows an example of the configuration of an RFID tag 30 provided on the electronic component storage reel 20.

[0011] As shown in FIG. 2, the tape 21 includes a carrier tape 22 and a cover tape 23 that covers the surface side of the carrier tape 22. The carrier tape 22 is formed in a long strip shape using flexible materials such as resin or paper. The carrier tape 22 includes multiple storage sections 22a and multiple feed holes 22b. The storage sections 22a are recesses that are rectangular in plan view and open to the surface side of the carrier tape 22. Each storage section 22a stores one electronic component 10. The electronic component 10 may be, for example, a semiconductor chip or a multilayer ceramic capacitor, and is, for example, a small electronic component with a rectangular parallelepiped shape and a longitudinal length of 1.2 mm or less. The storage sections 22a are arranged in a row at predetermined intervals along the longitudinal direction of the carrier tape 22. The storage sections 22a are biased to one side in the width direction of the carrier tape 22.

[0012] The feed holes 22b are circular through-holes that penetrate the carrier tape 22 from front to back. The feed holes 22b are arranged in a row at predetermined intervals in the longitudinal direction of the carrier tape 22. The feed holes 22b are arranged offset to the opposite side of the storage section 22a in the width direction of the carrier tape 22. Teeth of a transport sprocket (not shown) fit into the feed holes 22b. The tape 21 is transported by rotation of the transport sprocket.

[0013] The cover tape 23 is made of, for example, a transparent, flexible resin, and is a long, strip-shaped adhesive tape with one adhesive surface. The cover tape 23 is attached to the carrier tape 22 so that the adhesive surface is in close contact with the surface of the carrier tape 22, covering each storage section 22a, but not blocking the feed holes 22b. As a result, the electronic components 10 are stored in a sealed state in the storage sections 22a. The tape 21 storing the multiple electronic components 10 is wound around the reel 25 so that the surface to which the cover tape 23 is attached faces the inner periphery. The multiple electronic components 10 are transported together with the reel 25.

[0014] 2, an RFID tag 30 is attached to one end of the tape 21. The RFID tag 30 may be attached to the other end of the tape 21. Alternatively, the RFID tag 30 may be attached to both one end and the other end of the tape 21. Alternatively, the RFID tag 30 may be attached to the reel 25.

[0015] As shown in Fig. 3, the RFID tag 30 is a passive transponder having a rectangular resin sheet 30a as a base material, an RFID chip 30b consisting of a semiconductor integrated circuit, and multiple antennas 30c for communicating with external devices. The RFID chip 30b and the antennas 30c are affixed to the sheet 30a. The RFID tag 30 may be of a type in which the RFID chip 30b and the antennas 30c are embedded in the sheet 30a. It may also be of a type that includes a power supply. The RFID chip 30b includes a CPU, memory, communication circuits, etc.

[0016] The RFID tag 30 can be of a type with memory that cannot be rewritten (RO: Read Only), a type that can be rewritten once (WORM: Write Once Read Many), or a type that can be rewritten (R / W: Read and Write), etc. When the RFID tag 30 is of the RO or WORM type, less information can be written compared to the R / W type, but the cost is lower.

[0017] The RFID tag 30 of this embodiment has good reception sensitivity and is easy to read and write information when receiving signals from a direction intersecting the surface of the base sheet 30a. In particular, when receiving signals perpendicular to the surface of the sheet 30a or at an angle close to that, the reception sensitivity is high and reading and writing is easier.

[0018] FIG. 4 shows a cutaway view of reel 25. As shown in FIG. 4, reel 25 has a winding core 26 and a pair of disk-shaped flanges 27 disposed at both axial ends of winding core 26. Reel 25 is a resin molded body. Tape 21 containing electronic components 10 is wound around winding core 26, and tape 21 is sandwiched between the pair of flanges 27 to form electronic component storage reel 20 shown in FIG. 1. Electronic component storage reel 20 stores, for example, several hundred electronic components 10. An engagement hole 26b is provided at the center of winding core 26, with which a rotation shaft (not shown) that rotatably supports reel 25 engages.

[0019] As shown in FIG. 4, the winding core 26 of the reel 25 has a slit 26a extending along the circumferential direction of the winding core 26. The tip 21a of the tape 21, on which the RFID tag 30 is provided, is inserted into this slit 26a, and the tape 21 is wound around the winding core 26. The tip 21a of the tape 21 is inserted into the slit 26a with its surface direction approximately perpendicular to the axial direction of the winding core 26. The portion of the tape 21 protruding from the slit 26a onto the outer peripheral surface of the winding core 26 is folded so that the surface side to which the cover tape 23 is attached overlaps the outer peripheral surface of the winding core 26, and the tape 21 is wound around the winding core 26. As a result, the RFID tag 30 provided on the tip 21a of the tape 21 is arranged on the winding core 26 facing the side surface 26c of the winding core 26, as shown in FIG. 5. As a result, only the thin side surface 26c of the winding core 26 exists between the outside and the RFID tag 30, and read / write signals can be easily received at an angle perpendicular to or close to that angle with respect to the surface of the RFID tag 30. This structure can therefore solve the problem of making it easier to read and write to the RFID tag 30.

[0020] Furthermore, when the RFID tag 30 is attached to the other end of the tape 21, the surface of the RFID tag 30 is arranged along the outer peripheral surface of the winding core 26, facilitating reading and writing from the radial direction of the reel 25, which is perpendicular to the outer peripheral surface. Furthermore, when the RFID tag 30 is attached to both one end and the other end of the tape 21, reading from the side and from either of the above-mentioned radial directions becomes easy.

[0021] The slit 26a of the winding core 26 may have a general shape extending in the axial direction of the winding core 26. In this case, the tape 21 with the tip portion 21a inserted into the slit 26a can be wound around the winding core 26 as is without being folded as described above.

[0022] 6A shows the hardware configurations for managing electronic component 10 provided by component manufacturer G, which manufactures electronic component 10, and set manufacturer S, which uses electronic component 10. Component manufacturer G is an example of a manufacturer-side facility that manufactures electronic component 10. Set manufacturer S is an example of a user-side facility that uses electronic component 10.

[0023] 7, a unique ID 30X is written to the RFID tag 30 as a unique number for identifying the electronic component storage reel 20. The unique ID 30X is written to the RFID chip 30b. The unique ID 30X includes a character string or sequence of multiple numbers, symbols, alphabets, etc., and is different for each RFID tag 30. Here, the unique IDs that are different for each RFID tag 30 are collectively referred to as the unique ID 30X.

[0024] If the RFID tag 30 is an RO tag, the RFID tag 30, on which the unique ID 30X has been written in advance and stored, is affixed to the tape 21. If the RFID tag 30 is a WORM or R / W tag, the unique ID 30X is written to the RFID tag 30 by the writer unit 40 and then stored. The unique ID 30X may be written to the RFID tag 30 before the RFID tag 30 is affixed to the tape 21, after the RFID tag 30 is affixed to the tape 21, or after the RFID tag 30 has been affixed to the tape 21 and the tape 21 has been wound around the reel 25.

[0025] 6A, the component manufacturer G is provided with a writer unit 40 capable of writing a unique ID 30X linked to manufacturer information, which is information on the part of the component manufacturer G, to the RFID tag 30 attached to the electronic component storage reel 20 by being affixed to the tape 21, a reader unit 42 that reads the unique ID 30X linked to the manufacturer information recorded on the RFID tag 30 attached to the electronic component storage reel 20, and a database server 44. The writer unit 40 and the reader unit 42 may be integrated into a reader / writer unit. The database server 44 is prepared on the part of the component manufacturer G.

[0026] The writer unit 40 writes the unique ID 30X and the manufacturer information to the RFID tag 30. The unique ID 30X and the manufacturer information are linked to each other and stored in the database server 44. The reader unit 42 reads the unique ID 30X written in the RFID tag 30. After parts manufacturer G reads the unique ID 30X using the reader unit 42, the manufacturer can access the database server 44 and read the manufacturer information that has been linked to the unique ID 30X and stored in the database server 44.

[0027] The database server 44 on the part manufacturer G's side can be connected to a cloud 60 on the Internet together with a database server 54 on the set manufacturer S's side, which will be described later. Note that "cloud" is an abbreviation for cloud computing. Cloud computing is a general term for services that make various resources such as software, hardware, databases, and storage areas available via communication lines such as the Internet. In this embodiment, the cloud 60 is an example of an external storage device, and more specifically, a storage area in cloud computing is an example of an external storage device.

[0028] The external storage device does not have to be a storage area in cloud computing, but may be any storage device that can be accessed by parts manufacturer G and set manufacturer S via a communication line. Database server 44 and database server 54 may be located on cloud 60.

[0029] As shown in FIG. 6B , the cloud 60 has a manufacturer-side information storage area 60G that stores manufacturer-side information, and a user-side information storage area 60S that stores user-side information on the side of the set maker S, which will be described later. The unique ID 30X and some or all of the manufacturer-side information stored in the database server 44 on the part maker G side are copied and stored in the cloud 60. The unique ID 30X and some or all of the user-side information stored in the database server 54 on the set maker S side are copied and stored in the cloud 60. By both accessing the cloud 60, the part maker G and the set maker S can share information linked to the unique ID 30X with each other.

[0030] The writer unit 40 includes a plurality of RFID writers 41 capable of writing information contactlessly. Each of the plurality of RFID writers 41 is placed at a predetermined location in the factory of parts manufacturer G. The RFID writer 41 copies and stores all or part of the unique ID 30X and manufacturer-side information read from the database server 44 in a manufacturer-side information storage area 60G of the cloud 60. The reader unit 42 includes a plurality of RFID readers 43 capable of reading the unique ID 30X linked to the manufacturer-side information contactlessly. Each of the plurality of RFID readers 43 is placed at a predetermined location in the factory of parts manufacturer G. The information read by the RFID reader 43 is stored in the database server 44 and the manufacturer-side information storage area 60G of the cloud 60.

[0031] The set maker S includes a writer unit 50 capable of writing a unique ID 30X linked to user information, which is information on the set maker S side, to the RFID tag 30 provided on the electronic component storage reel 20, a reader unit 52 that reads the unique ID 30X recorded on the RFID tag 30 provided on the electronic component storage reel 20, a database server 54, and a mounter 56. The mounter 56 is an example of a mounting device. Note that if the RFID tag 30 is a WORM or R / W type, the writer unit 50 may be omitted.

[0032] The writer unit 50 writes the unique ID 30X and the user information to the database server 54. In the database server 54, the unique ID 30X and the user information are stored in association with each other. The reader unit 52 reads the unique ID 30X written in the RFID tag 30. When the reader unit 52 reads the unique ID 30X, it can access the database server 54 and read the user information stored in the database server 54 in association with the unique ID 30X.

[0033] The writer unit 50 includes a plurality of RFID writers 51 capable of writing information contactlessly. Each of the plurality of RFID writers 51 is disposed at a predetermined location in the factory of the set manufacturer S. The RFID writer 51 may write and record the unique ID 30X linked to the user information and manufacturer information on the RFID tag 30. The reader unit 52 includes a plurality of RFID readers 53 capable of reading the unique ID 30X contactlessly. The reader unit 52 is an example of a first reading unit. Each of the plurality of RFID readers 53 is disposed at a predetermined location in the factory of the set manufacturer S. Information read by the RFID reader 53 is stored in the database server 54 and the user information storage area 60S of the cloud 60.

[0034] At the component manufacturer G, the reader unit 42 can read all or part of the user information (e.g., the number of electronic components 10 used) that is linked to the unique ID 30X and stored in the user-side information storage area 60S of the cloud 60. At the set manufacturer S, the reader unit 52 can read all or part of the manufacturer information (e.g., the number of electronic components 10 produced) that is linked to the unique ID 30X and stored in the manufacturer-side information storage area 60G of the cloud 60.

[0035] The mounter 56 is a device that arranges and mounts at least one electronic component 10 on an electronic circuit board included in an electronic device set. The mounter 56 includes a plurality of component supply devices 57. An electronic component storage reel 20 is set in each component supply device 57, and the tape 21 is unwound to supply the electronic component 10 to the mounter 56.

[0036] As shown in Fig. 8, a designated unique ID 57X is electronically written and stored in each component supply device 57 of the mounter 56. Each component supply device 57 of the mounter 56 also has an RFID reader 58 that reads the RFID tag 30 provided on the electronic component storage reel 20. The designated unique ID 57X is an example of a designated unique number. The RFID reader 58 is an example of a second reading unit.

[0037] Component manufacturer G transports and stores a plurality of electronic components 10 manufactured in its factory in the form of electronic component storage reels 20, and ships them to set manufacturer S. Set manufacturer S receives a plurality of electronic component storage reels 20 and mounts the plurality of electronic components 10 in the electronic component storage reels 20 onto electronic circuit boards provided in electronic device sets using a mounter 56. Set manufacturer S manufactures electronic circuit boards and the like.

[0038] As shown in FIG. 9, component manufacturer G performs manufacturer-side step S1. Manufacturer-side step S1 at component manufacturer G includes the process of packaging, inspecting, and shipping electronic components 10. Furthermore, set manufacturer S performs user-side step S2. User-side step S2 at set manufacturer S includes the process of receiving, storing, manufacturing, and processing electronic components 10. At component manufacturer G, a plurality of manufactured electronic components 10 are stored in tape 21, and the tape 21 is wound around reel 25 to form electronic component storage reels 20. A plurality of electronic component storage reels 20 are shipped from component manufacturer G. The plurality of electronic component storage reels 20 shipped from component manufacturer G are received at set manufacturer S and used.

[0039] 10 and 11, the flow of electronic components 10 at component manufacturer G and set manufacturer S will be described. Note that the "reel" in FIGS. 10 and 11 refers to electronic component storage reel 20.

[0040] [Manufacturer step at parts manufacturer G] FIG. 10 shows details of step S1 on the manufacturer side, which is the flow of electronic component 10 on the component manufacturer G side.

[0041] The component manufacturer G prepares in advance a database server 44 for storing manufacturer-side information (described later) (step S101). The component manufacturer G also prepares a unique ID 30X for identifying each electronic component storage reel 20 for each electronic component storage reel 20 (step S102).

[0042] (Packaging process) In the packaging process, if the RFID tag 30 is WORM or R / W, the prepared unique ID 30X is written to the RFID tag 30 before or after it is attached to the electronic component storage reel 20 (step S103). Next, the manufactured electronic components 10 are stored in tape 21, and the tape 21 is wound around reel 25 to store the electronic component storage reel 20 (step S104). This completes the preparation of the electronic component storage reel 20, which stores the multiple electronic components 10 and includes the RFID tag 30 with the unique ID 30X stored therein.

[0043] If the RFID tag 30 provided on the electronic component storage reel 20 is an RO, the unique ID 30X is stored in advance in the RFID tag 30. In this case, step S103 is omitted, and multiple electronic components 10 are stored on the tape 21.

[0044] During the packaging process, the manufacturer information is linked to the unique ID 30X stored in the RFID tag 30 attached to the electronic component storage reel 20 and stored in the database server 44. The information is then stored in the manufacturer information storage area 60G of the cloud 60 (step S105). The manufacturer information is a plurality of pieces of information related to the electronic components 10 stored on the tape 21, set or stored by the component manufacturer G. Examples of the manufacturer information include the lot number of the electronic components 10, the number of electronic components 10 stored on the electronic component storage reel 20, product information such as the performance of the electronic components 10, environmental information related to the electronic components 10, and the inspection number of the electronic components 10. Depending on the type of electronic component 10, a moisture sensitivity level (MSL) is recorded. The MSL indicates the risk of volume expansion due to evaporation of moisture contained in the electronic components 10, which can lead to failure. Information about the manufacturing process of the electronic components 10 can also be obtained via the lot number. In this case, the unique ID 30X is used as a key, or a key stored in the RFID tag 30 is used to obtain the information.

[0045] In the factory of component manufacturer G, a predetermined RFID reader 43 reads the RFID tag 30 of the electronic component storage reel 20, and the manufacturer information linked to the unique ID 30X is read to manage the electronic component storage reel 20. To read the unique ID 30X of the RFID tag 30, for example, as shown in Fig. 12 , the unique ID 30X of the RFID tag 30 of the electronic component storage reel 20 placed on a table 61 is read by the RFID reader 43 installed on the table 61.

[0046] The electronic component storage reels 20, the unique IDs 30X of which have been read, are transported within the factory and stored in a predetermined storage location (step S106). Until the next inspection and processing stage, the unique IDs 30X stored in the RFID tags 30 are used for, for example, inventory information management within the factory, location management based on movement routes, and crime prevention management. Inventory information management, location management, and crime prevention management are performed based on information read by an RFID reader 43 installed within the factory. The RFID reader 43 is installed, for example, at a gate installed in an aisle or an entrance / exit to a room, and reads the unique ID 30X recorded in the RFID tag 30 when an electronic component storage reel 20 passes through.

[0047] Inventory information management is a method of managing inventory by checking whether electronic component storage reels 20 are stored in a predetermined storage location. For example, when a person passes through a gate located at the entrance to a predetermined storage location, the RFID reader 43 located at the gate reads the unique ID 30X of the RFID tag 30, thereby confirming that the electronic component storage reel 20 is in stock.

[0048] Location management is a management method for tracking the location of electronic component storage reels 20 within a factory as they are transported through multiple gates and as they enter and exit designated rooms. Since RFID tags 30 cannot be detected by RFID readers 43 or the like when they are housed in metal cases, the location can be more accurately tracked by using a metal detector or X-ray inspection device in combination.

[0049] In the case of security management, for example, if an electronic component storage reel 20 is taken outside the factory without having its shipment confirmed by, for example, an RFID tag 30, it is determined that it has not been shipped via the regular route, and measures such as issuing a warning are taken.

[0050] (Inspection and shipping process) In the inspection and shipping process, the electronic component storage reel 20 is picked from the storage location (step S107), and then the unique ID 30X stored in the RFID tag 30 attached to the picked electronic component storage reel 20 is read (step S108).

[0051] 13 , for example, the electronic component storage reel 20 is picked from a storage location 62 such as a rack and placed on a transport cart 63, and the unique ID 30X of the RFID tag 30 on the cart 63 is read by an RFID reader 43 via a sensor 64. The RFID reader 43 is installed at an appropriate location on the cart 63. As a result, information that the electronic component storage reel 20 is being shipped is entered into a database server 44. When the electronic component storage reel 20 is located farther away than the readable distance of the RFID reader 43, it is preferable to read the unique ID 30X recorded on the RFID tag 30 via the sensor 64 located close to the electronic component storage reel 20.

[0052] Here, new manufacturer-side information is further stored in the manufacturer-side information storage area 60G of the cloud 60 via the database server 44, linked to the unique ID 30X provided on the RFID tag 30 of the picked electronic component storage reel 20 (step S109). The new manufacturer-side information here is, for example, but is not limited to, the part number used by the set manufacturer S, the order number from the set manufacturer S, the factory number of the component manufacturer G, the date of production, the vendor number, etc.

[0053] In this embodiment, as shown in FIG. 14 , a label 71 is affixed to the reel 25 of the electronic component storage reel 20 (step S110). The label 71 is affixed to the surface of one of the flanges 27. At least one of the manufacturer information items associated with the unique ID 30X and stored in the manufacturer information storage area 60G of the database server 44 and the cloud 60, or other manufacturer information required for shipping, is printed on the label 71 in advance. The manufacturer information printed on the label 71 can be visually confirmed. The label 71 may include at least one of a one-dimensional barcode and a two-dimensional barcode associated with the manufacturer information.

[0054] The unique ID 30X of the RFID tag 30 of each electronic component storage reel 20 is read by the RFID reader 43, and the electronic component storage reel 20 is inspected (step S111).

[0055] The inspected electronic component storage reels 20 are packed in boxes and shipped to the set manufacturer S (step S112). For example, as shown in Fig. 15, a predetermined number of electronic component storage reels 20 are stored in one exterior box 81, and the plurality of exterior boxes 81 are stored in a two-tiered state in one outer transport box 82, and the plurality of outer transport boxes 82 are further loaded on a pallet 83.

[0056] The outer box 81 may include an RFID tag 31 on which the unique IDs 30X of the RFID tags 30 of the electronic component storage reels 20 stored in the outer box 81 are recorded. The transport outer box 82 may include an RFID tag 32 on which the RFID tags 31 of the electronic component storage reels 20 stored in the transport outer box 82 are recorded. The pallet 83 may include an RFID tag 33 on which the RFID tags 32 of the electronic component storage reels 20 loaded on the pallet 83 are recorded. In this case, the unique IDs 30X of the stored electronic component storage reels 20 are linked to the RFID tags 31, 32, and 33 and stored in the manufacturer-side information storage area 60G of the database server 44 and the cloud 60. This allows the unique IDs 30X of the electronic component storage reels 20 to be read collectively for each outer box 81, each transport outer box 82, and each pallet 83.

[0057] When a plurality of outer transport boxes 82 are loaded onto a pallet 83 as described above, the pallet 83 is transported to a shipping location by a forklift 65 as shown in Fig. 16. When the forklift 65 passes through a gate 66, the RFID reader 43 reads the RFID tags 31, 32, and 33 via the sensor 64 arranged at the gate 66, thereby enabling shipping management to confirm that the plurality of electronic component storage reels 20 linked to the RFID tags 31, 32, and 33 have been shipped.

[0058] Fig. 17 shows another mode for reading the RFID tag 30 at the time of shipment. In Fig. 17, an outer box 81 containing a plurality of electronic component storage reels 20 being transported on a transport platform 67 is transported through a tunnel-shaped gate 68, and the unique ID 30X of the RFID tag 30 is read by an RFID reader 43 via a sensor 64 provided at the gate 68. The RFID reader 43 accesses a database server 44 and reads manufacturer information linked to the unique ID 30X that has been read.

[0059] [User steps at Set Maker S] FIG. 11 shows details of user-side step S2, which is the flow of electronic component 10 on the set manufacturer S side. In the set manufacturer S, a database server 54 for storing user-side information, which will be described later, is prepared in advance (step S201).

[0060] (Arrival process) In the receiving process, first, a plurality of electronic component storage reels 20 are received at the factory of the set maker S (step S202). In the receiving process, the RFID tag 30 of the received electronic component storage reel 20 is read by a predetermined RFID reader 53, and the unique ID 30X stored in the RFID tag 30 is read (step S203). As a result, the set maker S obtains manufacturer-side information via the cloud 60 based on the read unique ID 30X (step S204). The obtained manufacturer-side information includes the lot number of the electronic components 10, the quantity of electronic components 10 stored in the electronic component storage reel 20, product information such as the performance of the electronic components 10, environmental information about the electronic components 10, and the inspection number of the electronic components 10.

[0061] 15 , when the electronic components 10 arrive at the set manufacturer S with a plurality of electronic component storage reels 20 stored in an outer box 81, or with a plurality of outer boxes 81 stored in an outer transport box 82, the RFID tag 31 on the outer box 81 and the RFID tag 32 on the outer transport box 82 are read by the RFID reader 53. This makes it possible to read the unique IDs 30X of the plurality of electronic component storage reels 20 collectively for each outer box 81 or each outer transport box 82.

[0062] The set maker S stores the manufacturer information obtained based on the unique ID 30X read from the RFID tag 30 of the received electronic component storage reel 20 in the user information storage area 60S of the cloud 60 (step S205). The set maker S may also store predetermined user information required by the set maker S as additional information in the user information storage area 60S of the cloud 60 (step S206).

[0063] In this embodiment, as shown in Fig. 18, an identification sticker 72 unique to the set manufacturer S is affixed to the electronic component storage reel 20 (step S207). The identification sticker 72 is a sticker having one of a single color such as red, blue, or yellow, and may be affixed to the label 71. Depending on the color of the identification sticker 72, a distinguishing treatment is performed on the electronic component storage reel 20 within the set manufacturer S. For example, the production line, production order, etc. are selected depending on the color of the identification sticker 72.

[0064] (Storage process) At the set maker S, when the electronic component storage reel 20 is stored in a predetermined storage location or picked from the storage location and transported before moving to the manufacturing process, the set maker S also reads the unique ID 30X of the RFID tag 30 with a predetermined RFID reader 53 to manage the location of the electronic component storage reel 20, that is, manage to detect its location (step S208). In addition, like the component maker G, inventory information management and crime prevention management of the electronic component storage reel 20 can be performed by reading the RFID tag 30. When the RFID tag 30 is stored in a metal case, it cannot be detected by the RFID reader 53 or the like, so a metal detector or X-ray inspection device is also used.

[0065] 19, at the set manufacturer S, a reel handler 90 handling the electronic component storage reel 20 reads the unique ID 30X on the RFID tag 30, and identifies the reel handler 90 as the handler of the electronic component storage reel 20 from the read unique ID 30X (step S209). The reel handler 90 may be, for example, a worker, a work robot, or a transport device such as an automated guided vehicle that transports the electronic component storage reel 20. If the reel handler 90 is a worker, the RFID tag 30 is read using a portable RFID reader. If the reel handler 90 is a work robot or an automated guided vehicle, the RFID tag 30 is read using an RFID reader mounted on the work robot or the automated guided vehicle.

[0066] (manufacturing process) In the manufacturing process, the electronic component storage reels 20 are delivered from a storage location to the mounter 56, and the electronic component storage reels 20 are set in each of the multiple component supply devices 57 provided in the mounter 56. Each component supply device 57 reads the unique ID 30X of the RFID tag 30 provided in the electronic component storage reel 20 using an RFID reader 58, and compares the read unique ID 30X with the designated unique ID 57X designated for the component supply device 57 itself (step S210).

[0067] This allows confirmation of whether the electronic component storage reel 20 is the electronic component storage reel 20 that stores the electronic component 10 to be mounted by the component supply device 57, thereby preventing mix-up of the electronic component 10. For example, if an electronic component storage reel 20 that stores an incompatible electronic component 10 is set in the component supply device 57, the component supply device 57 will not operate, the electronic component storage reel 20 will be removed from the component supply device 57, and the next electronic component storage reel 20 will be set.

[0068] The tape 21 is unwound from the electronic component storage reel 20 set in the component supply device 57, and the electronic components 10 are supplied one by one from the tape 21 to the mounter 56, where the electronic components 10 are mounted on the electronic circuit board (step S211).

[0069] Each component supply device 57 grasps the consumption amount of electronic components 10 arranged on the electronic circuit board and the remaining amount of electronic components 10 in the electronic component storage reel 20 based on the consumption amount, based on the information on the quantity of electronic components 10 stored in the electronic component storage reel 20 among the manufacturer information obtained in step S204. Then, when the remaining amount of electronic components 10 falls below a predetermined amount, another received electronic component storage reel 20 is prepared (step S212).

[0070] The consumption amount of electronic components 10 is linked to the unique ID 30X and stored in the database server 54, and is further stored in the manufacturer-side information storage area 60G of the cloud 60 (step S213). The component manufacturer G can quickly check the consumption amount of electronic components 10 at the set manufacturer S by reading the unique ID 30X. Note that the consumption amount of electronic components 10 at the set manufacturer S at this time may be transmitted to the component manufacturer G by electronic transmission means such as the Internet or a LAN, or by physical transmission means such as storing the amount on a recording medium such as a memory device or a CD-ROM and handing it over.

[0071] Meanwhile, the consumption amount of electronic components 10 is transmitted from the set maker S to the component maker G as described above. The component maker G predicts the remaining amount of electronic components 10 at the set maker S based on the consumption amount of electronic components 10 transmitted from the set maker S. When the remaining amount of electronic components 10 falls below a preset remaining amount, the component maker G starts the work of preparing electronic component storage reels 20 in preparation for shipment.

[0072] When all the electronic components 10 in the electronic component storage reel 20 have been mounted at the set maker S, the tape 21 from which the electronic components 10 have been removed is discarded (step S214). The empty reel 25 is returned to the component maker G for reuse. If the RFID tag 30 is affixed to the tape 21 but not to the reel 25, the reel 25 can be easily reused.

[0073] In the processing process after the manufacturing process, for example, the electronic component storage reel 20 with the remaining electronic components 10 is stored in a predetermined location as an intermediate inventory. In this case, the RFID tag 30 of the electronic component storage reel 20 is read by the RFID reader 53, and the remaining amount of the electronic component storage reel 20 is managed as an intermediate inventory (step S215).

[0074] In addition, during the processing process, by reading the RFID tag 30 on the electronic component storage reel 20, it is possible to perform production trend management based on the type of electronic component 10 used or the quantity of electronic device sets being manufactured, as well as security management of the electronic component storage reel 20.

[0075] The user-side information in step S206 may be stored in the cloud 60. Furthermore, the user-side information stored in the cloud 60 may be made accessible to the parts manufacturer G. By making the information accessible to the parts manufacturer G, the parts manufacturer G can grasp the specifications and inventory information of the set manufacturer S, and therefore can predict the requests of the set manufacturer S in advance and can respond flexibly to the requests of the set manufacturer S.

[0076] The data stored on the cloud 60 may be stored using a blockchain. By using a blockchain, it becomes difficult to tamper with the data stored on the cloud 60, and the reliability of the data stored on the cloud 60 increases.

[0077] In the above embodiment, the unique ID 30X written to the RFID tag 30 is common to the component manufacturer G and the set manufacturer S (common unique ID), and one unique ID 30X is used consistently from component manufacturer G to set manufacturer S. However, as shown in Fig. 20, the component manufacturer G may use a unique ID 30Y unique to component manufacturer G, and the set manufacturer S may use a unique ID 30Z unique to set manufacturer S. In this case, the component manufacturer unique ID 30Y and the set manufacturer unique ID 30Z are linked to the common unique ID 30X, allowing various pieces of information written to the RFID tag 30 to be shared.

[0078] Alternatively, either the part manufacturer unique ID 30X or the set manufacturer unique ID 30Z may be the same as the unique ID 30X, and either the part manufacturer unique ID 30X or the set manufacturer unique ID 30Z may be linked to the unique ID 30X.

[0079] According to the embodiment described above, the following effects are achieved.

[0080] (1) The method for managing electronic components according to this embodiment includes manufacturer-side steps carried out by a component manufacturer G, which is a manufacturer-side facility where a manufacturer manufactures electronic components 10, including the steps of preparing an electronic component storage reel 20 on which a tape 21 storing a plurality of electronic components 10 is wound and on which an RFID tag 30 storing a unique ID 30X as a unique number is attached to at least one of the tape 21 and the reel 25, linking the manufacturer-side information with the unique ID 30X and storing it in a manufacturer-side information storage area 60G of the cloud 60, and shipping the electronic component storage reel 20; and user-side steps carried out by a set manufacturer S, which is a user-side facility where a user uses the electronic components 10 manufactured by the component manufacturer G, including the steps of receiving the shipped electronic component storage reel 20, reading the unique ID 30X stored in the RFID tag 30, and obtaining the manufacturer-side information stored in the manufacturer-side information storage area 60G of the cloud 60 based on the read unique ID 30X.

[0081] This allows for various management forms to be realized on both the component manufacturer G side and the set manufacturer S side for the electronic component storage reel 20 that stores a plurality of electronic components 10, by using the unique ID 30X of the RFID tag 30 provided on the electronic component storage reel 20. Furthermore, by using the unique ID 30X written to the RFID tag 30, the electronic components 10 can be managed consistently from the component manufacturer G to the set manufacturer S.

[0082] (2) The method for managing electronic components according to this embodiment is a manufacturer-side step performed by a component manufacturer G, which is a manufacturer-side facility where the manufacturer manufactures electronic components 10. The manufacturer-side step includes the steps of preparing a reel 25 on which a tape 21 storing a plurality of electronic components 10 is wound, and an electronic component storage reel 20 on which an RFID tag 30 is attached to at least one of the tape 21 and the reel 25; preparing a unique ID 30X as a unique number linked to manufacturer-side information; and linking the manufacturer-side information to the unique ID 30X and storing it in a manufacturer-side information storage area 60G of the cloud 60. and manufacturer-side steps including a step of writing the unique ID 30X to the RFID tag 30 and a step of shipping the electronic component storage reel 20. User-side steps carried out by a set manufacturer S as a user-side facility where a user uses the electronic component 10 manufactured by the component manufacturer G include a step of receiving the shipped electronic component storage reel 20, a step of reading the unique ID 30X stored in the RFID tag 30, and a step of obtaining the manufacturer-side information stored in the manufacturer-side information storage area 60G of the cloud 60 based on the read unique ID 30X.

[0083] This allows for various management forms to be realized on both the component manufacturer G side and the set manufacturer S side for the electronic component storage reel 20 that stores a plurality of electronic components 10, by utilizing the unique ID 30X of the RFID tag 30 provided on the electronic component storage reel 20. Furthermore, by utilizing the RFID tag 30, consistent component management can be performed from the component manufacturer G to the set manufacturer S.

[0084] (3) The method for managing electronic components according to this embodiment further includes, in the manufacturer step, a step of reading manufacturer information based on the unique ID 30X, creating a label 71 based on the read manufacturer information, and attaching the label 71 to the electronic component storage reel 20.

[0085] This allows the manufacturer's information to be visually confirmed by looking at the label 71, and management based on the manufacturer's information can be carried out quickly without the need for a reading device such as an RFID reader.

[0086] (4) The electronic component management method according to this embodiment further includes, in the manufacturer's step, a step of reading the unique IDs 30X from the RFID tags 30 of the multiple electronic component storage reels 20 in a batch when shipping the electronic component storage reels 20 containing multiple electronic components 10.

[0087] This allows the component manufacturer G to avoid the trouble of reading the RFID tags 30 on the electronic component storage reels 20 one by one, thereby improving management efficiency.

[0088] (5) The electronic component management method according to this embodiment further includes, in the user step, a step of reading the unique IDs 30X from the RFID tags 30 of multiple electronic component storage reels 20 in bulk when the shipped electronic component storage reels 20 are received.

[0089] This allows the set manufacturer S to eliminate the need to read the RFID tags 30 of the electronic component storage reels 20 one by one, thereby improving management efficiency.

[0090] (6) The method for managing electronic components according to this embodiment further includes, in a user-side step, a step of reading the RFID tag 30 using an RFID reader 53 as a first reading unit installed at a predetermined location of the set manufacturer S to detect the location of the electronic component storage reel 20.

[0091] This allows the location of the electronic component storage reels 20 to be constantly known, enabling various management tasks such as inventory information management, location management, and crime prevention management.

[0092] (7) The method for managing electronic components according to this embodiment further includes, in the user side step, a step of identifying the reel handler 90 by having the reel handler 90 located at a predetermined location of the set manufacturer S read the RFID tag 30.

[0093] This allows the set manufacturer S to always identify the workers, transport vehicles, etc. that handled the electronic component storage reel 20, and allows management such as accurately understanding the current location of the electronic component storage reel 20.

[0094] (8) The method for managing electronic components according to this embodiment further includes, in a user-side step, a step in which a component supply device 57 as an implementation device places each of the plurality of electronic components 10 stored in the electronic component storage reel 20 on an electronic circuit board, and the component supply device 57 stores a designated unique ID 57X as a designated designated unique number and has an RFID reader 58 as a second reading unit that reads the RFID tag 30, and compares the unique ID 30X stored in the RFID tag 30 read by the RFID reader 58 with the designated unique ID 57X designated by the component supply device 57.

[0095] This allows confirmation of whether the unique ID 30X of the electronic component storage reel 20 is the electronic component storage reel 20 that stores the electronic component 10 to be mounted by the component supply device 57, thereby preventing the electronic component 10 from being mixed up.

[0096] (9) The method for managing electronic components according to this embodiment further includes a step in which, in a manufacturer-side step, quantity information of the electronic components 10 stored in the electronic component storage reel 20 is stored in the manufacturer-side information storage area 60G of the cloud 60 as manufacturer-side information, and in a user-side step, based on the quantity information obtained based on the unique ID 30X, the consumption amount of the electronic components 10 placed on the electronic circuit board by the component supply device 57 is determined, and based on the consumption amount, another electronic component storage reel 20 that has arrived is prepared.

[0097] As a result, the set manufacturer S can quickly replace the electronic component storage reel 20 that has finished supplying the electronic components 10 to the component supply device 57 with a new electronic component storage reel 20 after the supply of the electronic components 10 is completed, and can continuously mount the electronic components 10 even if the electronic component storage reel 20 is replaced, thereby improving productivity.

[0098] (10) In the electronic component management method according to this embodiment, the consumption amount of the electronic component 10 is linked to the unique ID 30X, and the unique ID 30X is stored in the user-side information storage area 60S of the cloud 60 and transmitted to the manufacturer.

[0099] This allows the component manufacturer G to accurately prepare for the process of storing the electronic components 10 in the electronic component storage reels 20 based on the consumption amount of the electronic components 10 at the set manufacturer S.

[0100] (11) In the method for managing electronic components according to this embodiment, the manufacturer prepares electronic component storage reels 20 based on the consumption amount of electronic components 10 transmitted from the user.

[0101] This allows the component manufacturer G to efficiently prepare the electronic component storage reels 20 based on the consumption of the electronic components 10 on the set manufacturer S side.

[0102] (12) In the method of managing electronic components according to this embodiment, component manufacturer G uses component manufacturer G's unique ID 30Y as the unique ID, and set manufacturer S uses set manufacturer S's unique ID 30Z as the unique ID, and either component manufacturer G's unique ID 30Y or set manufacturer S's unique ID 30Z is the same as unique ID 30X, and either component manufacturer G's unique ID 30Y or set manufacturer S's unique ID 30Z is linked to unique ID 30X.

[0103] (13) In the method for managing electronic components according to this embodiment, component manufacturer G uses component manufacturer G's unique ID 30Y as the unique ID, and set manufacturer S uses set manufacturer S's unique ID 30Z as the unique ID, and component manufacturer's unique ID 30Y and set manufacturer's unique ID 30Z are linked to a common unique ID 30X.

[0104] This allows either parts manufacturer G or set manufacturer S, or either parts manufacturer G or set manufacturer S, to use their own unique ID (unique ID 30Y, unique ID 30Z), so that each manufacturer can operate without changing the conventional method or pattern of assigning unique IDs.

[0105] Although the embodiments have been described above, the present invention is not limited to the above-described embodiments, and modifications and improvements within the scope of achieving the object of the present invention are included in the present invention.
