DETAILED DESCRIPTION OF THE INVENTION

[0007] An embodiment of the present invention will be described with reference to the drawings. (First embodiment) As shown in FIG. 1, the manufacturing system 1 is a system for processing disks 5 and manufacturing HDDs 55 using the processed disks 5 as components. The manufacturing system 1 includes a processing system 10 and an assembly system 50. The processing system 10 is a system for manufacturing a magnetic disk by processing a disk 5 (workpiece) such as a disk-shaped aluminum alloy substrate or glass substrate. The assembly system 50 is a system provided on an assembly line. The assembly system 50 is a system for assembling HDDs 55 (hard disk drives) (units) using the disks 5 manufactured by the processing system 10 as components. In the manufacturing system 1, the facility where the processing system 10 is installed and the facility where the assembly system 50 is installed may be the same or different. A configuration in which the two facilities are different is preferable, for example, when the operators of the two facilities are different.

[0008] In the embodiments, a computer refers to an electronic calculator equipped with a storage device, a control device, an arithmetic device, etc., and the processing unit, assembly unit, management device, and inspection device are all included in the concept of a computer, as they are equipped with a storage device, a control device, etc. Furthermore, the computer is not limited to a configuration consisting of a single electronic calculator, and may be composed of multiple electronic calculators as necessary. The storage unit is a storage device such as a hard disk or semiconductor memory element for storing programs, information, etc. required for the operation of each device. The control unit is a device that performs the arithmetic processing required for the operation of each device and controls each device in an integrated manner. The control unit is composed of, for example, a CPU (Central Processing Unit). The control unit realizes various functions of the embodiment by appropriately reading and executing various programs stored in the storage unit.

[0009] (Processing System 10) The processing system 10 is a system provided in a processing line for processing the disk 5. The processing system 10 includes nine processing units 20, a transport cassette 30 (transport member), and a management device 40. The nine processing units 20 and the management device 40 are connected to each other via a communication network 2 such as a LAN, allowing communication therebetween.

[0010] (Processing section 20) The nine processing units 20 each perform nine different processes, such as a deposition process, a polishing process, a cleaning process, etc. Each processing unit 20 is equipped with a device corresponding to each process. In the embodiment, the reference numerals of the processing units 20 are enclosed in parentheses, and the reference numerals representing the processing types are written within the parentheses (for example, processing unit 20(W9)). Similarly, the reference numerals of the members included in each processing unit 20 are enclosed in parentheses (for example, polishing device 21(W8)). The processing units 20(W1) to 20(W9) process, in this order, the disk 5. For example, the processing unit 20(W9) processes the disk 5 in the next step after the processing unit 20(W8).

[0011] As shown in FIG. 2, for example, the eighth process processing section 20 (W8) includes a polishing device 21 (W8) for polishing the disk 5. The polishing apparatus 21 includes a turret 21a that is driven to rotate (see arrow θ21a). The turret 21a includes ten tables 21b that are also driven to rotate (see arrow θ21b). Each table 21b includes pockets 21c (placement areas) that accommodate and place five disks 5. Each table 21b is assigned identification information (1 to 10) for identifying each table 21b, and each pocket 21c is assigned identification information (1 to 5) for identifying each pocket 21c. In the embodiment, in order to identify the multiple pockets 21c, pocket numbers (identification information) are appropriately indicated and described. The pocket number is the symbol P plus "identification information of table 21b-identification information of pocket 21c" (for example, pocket number P1-1).

[0012] The polishing device 21 rotates the table 21b and rotates the turret 21a to move the disk 5 while pressing the polishing pad against the disk 5 stored in the pocket 21c. As a result, the disk 5 is polished while moving within the polishing device 21.

[0013] Each processing unit 20 includes a reader 22i, a reader 22o, a carry-in robot 23i, a carry-out robot 23o, a memory unit 25, and a control unit . The reader 22i is a device that communicates with the IC tag 32 of the transport cassette 30 transported from the processing section 20 in the preceding process, thereby reading and acquiring the identification information stored in the IC tag 32. The reader 22o is a device that communicates with the IC tag 32 of the transport cassette 30 that is to be transported to the processing section 20 for the next process, thereby reading and acquiring the identification information stored in the IC tag 32.

[0014] The loading robot 23i is a device that takes out the disks 5 stored in the transport cassette 30 one by one and loads them into the storage section of the processing device of each processing section 20 (for example, in the case of processing section 20 (W8), the pocket 21c of the polishing device 21 (W8)). The unloading robot 23o is a device that removes the disk 5 that has been processed in each processing section 20 from the storage section of the processing device (for example, in the case of processing section 20 (W8), from pocket 21c of polishing device 21 (W8)) and unloads it to the transport cassette 30.

[0015] The storage unit 25 includes a memory (temporary storage device), etc. The storage unit 25 temporarily stores slot numbers and processing information (described later). The control unit 26 controls the processing of the disk 5, controls the transmission of the processing record (see FIG. 4) to the management device 40, and the like.

[0016] (Transport cassette 30) 2, the transport cassette 30 is a container used to transport the disks 5 from each processing unit 20 to the outside of that processing unit 20. That is, the transport cassette 30 transports the disks 5 between each processing unit 20 and the processing unit 20 of the next process. The transport cassette 30 also transports the disks 5 between the processing unit 20 of the final process (W9) and the assembly unit 60 of the assembly system 50. At the disk 5 carry-in side of each processing section 20 (or assembly section 60), once all disks 5 have been removed from the transport cassette 30 sent from the previous process, the transport cassette 30 is returned to the previous process, and a new transport cassette 30 containing disks 5 is sent from the previous process. Also, at the disk 5 carry-out side of each processing section 20 (or assembly section 60), once all slots 31 (disk storage sections) of the transport cassette 30 have been filled with disks 5, the transport cassette 30 is sent to the next process, and the transport cassette 30 with all slots 31 empty is returned from the next process.

[0017] In the embodiment, for the sake of simplicity, an example is shown in which the multiple transport cassettes 30 are made of similar components, but this is not limiting. The transport cassette 30 on the disk 5 discharge side of each processing unit 20 preferably has a configuration, function, etc. that corresponds to the state after processing in each processing unit 20. For example, the number of disks 5 that can be accommodated, the external size, etc., may differ among the multiple transport cassettes 30 depending on the state after processing in each processing unit 20. In the embodiment, the reference numeral of the transport cassette 30 is enclosed in parentheses, and the reference numeral corresponding to the processing unit 20 to which it is transported is written within the parentheses. For example, the transport cassette 30 transported from processing unit 20(W8) to processing unit 20(W9) is referred to as transport cassette 30(8). The transport cassette 30 transported to processing unit 20(W1) is referred to as transport cassette 30(0).

[0018] Each transport cassette 30 has ten slots 31 and an IC tag 32 . The slots 31 are storage sections that store discs 5. The slots 31 have, for example, slits into which the discs 5 are inserted. The ten slots 31 are each assigned a slot number (S1 to S10). The slot number is identification information for the slot 31. For example, the slot number for the top slot 31 is "S1" and the slot number for the bottom slot 31 is "S10."

[0019] The IC tag 32 stores identification information for identifying the transport cassette 30. The IC tag 32 is rewritable. After all the discs 5 stored in the transport cassette 30 have been removed to the processing device, the transport cassette 30 is returned to the processing section 20 of the previous process to store discs 5 again. The identification information in the IC tag 32 is rewritten by a writer (not shown) while the transport cassette 30 is being returned from the processing section 20 to the processing section 20 of the previous process. As a result, the transport cassette 30 is given unique identification information each time it travels back and forth between two processing sections 20. The writer may be provided for each processing unit 20. Alternatively, the control unit 26 of each processing unit 20, a control unit 46 (described later) of the management device 40, or the like may control the writer to manage the timing of rewriting the IC tag 32, the identification information, etc.

[0020] (Management device 40) As shown in FIG. 1, the management device 40 is a computer capable of managing the machining system 10 in an integrated manner, and is, for example, a personal computer, a server, or the like. The management device 40 includes a storage unit 45 and a control unit 46 . The storage unit 45 includes a processing record storage unit 45a.

[0021] As shown in FIG. 4, the processing record storage unit 45a stores processing records as information relating to the processing history of each disk 5. The processing record is information that associates cassette information (at the time of loading), cassette information (at the time of unloading), and processing information. The cassette information (at the time of loading) is the cassette information at the time of loading from the previous process to each processing unit 20, and the cassette information (at the time of unloading) is the cassette information at the time of unloading from each processing unit 20 to the next process. The cassette information is identification information of the slot 31 of the transport cassette 30. That is, the cassette information is information in which the identification information of the IC tag 32 of the transport cassette 30 and the slot number of the slot 31 are associated with each other.

[0022] The processing information is information relating to the processing content of each processing unit 20. In the embodiment, the processing information includes the process type (W1 to W9), the table number of the table 21b, and the pocket number (that is, the identification information of the pocket 21c). The processing information may also include other processing content information (for example, surface pressure of the polishing pad, information on the abrasive (type of abrasive, temperature, etc.), processing time, processing speed, etc.). The control unit 46 controls communication with the plurality of processing units 20 and a management device 70 (described later), and performs processing related to information management of the processing record storage unit 45a.

[0023] (Assembly System 50) As shown in FIG. 1, the assembly system 50 includes an assembly section 60 and a management device 70 (unit management device). The assembly department 60 and the management device 70 are connected and capable of communication via a communication network 52 such as a LAN. The management device 70 and the management device 40 are connected and capable of communication via a communication network 53 such as a WAN.

[0024] (Assembly section 60) As shown in FIG. 3, the assembly section 60 executes a process for assembling the HDD 55 using the disks 5 processed by the processing system 10 as components. The assembly unit 60 includes a reader 62i, a carry-in robot 63i, a storage unit 65, and a control unit 66 (unit identification information assigning unit). Although detailed description will be omitted, the assembly section 60 includes various devices for assembling the HDD 55 (screw tightening machines, inspection devices, etc.). The reader 62i is a reading device similar to the reader 22i, and is a device that reads the identification information of the IC tag 32 of the transport cassette 30(9) that has been transported from the processing section 20(W9) that is the preceding process. The carry-in robot 63i is a device similar to the carry-in robot 23i, and takes out the disks 5 housed in the transport cassette 30(9) one by one and carries them into the assembly line.

[0025] The storage unit 65 includes a memory and the like, and temporarily stores information from when the disk 5 transported by the transport cassette 30(9) is carried into the assembly line until it is assembled into the HDD 55 as assembly information. The control unit 66 controls various devices in the assembly unit 60, controls transmission of assembly records (see FIG. 4) to the management device 70, and the like.

[0026] (Management device 70) The management device 70 is a computer capable of managing the assembly system 50 in an integrated manner, and is, for example, a personal computer, a server, or the like. The management device 70 includes a storage unit 75 and a control unit 76 . The storage unit 75 includes an assembly record storage unit 75a. As shown in FIG. 4, the assembly record storage unit 75a stores assembly records. The assembly record is information that associates cassette information of the four disks 5 incorporated in the HDD 55 with S / N (serial number). The S / N is identification information of the HDD 55 (unit identification information). The control unit 76 controls communication with the assembly unit 60 and the management device 40, and performs processing related to information management of the assembly record storage unit 75a.

[0027] [Processing of the processing system 10] The process from processing the disk 5 in the processing system 10 to assembling the HDD 55 in the assembly system 50 will be explained step by step. (Processing of the processing system 10) In the processing of the processing system 10, an example will be described in which the disk 5 is processed in the processing unit 20 (W8) and then transported by the transport cassette 30 to the processing unit 20 (W9).

[0028] (1) Carry-in processing As shown in FIG. 2, the control unit 26 and the reader 22i of the processing unit 20(W8) function as a conveyed member discharge information acquisition unit to acquire conveyed member discharge information. That is, when removing the disk 5 from the transport cassette 30(7), the control unit 26 of the processing unit 20(W8) controls the reader 22i to read the identification information (identification information of the transport member) of the IC tag 32 of the transport cassette 30(7).

[0029] The reader 22i may read the IC tag 32 only once when the transport cassette 30(7) is carried into the processing unit 20(W8). In this case, the IC tag 32 only needs to be read once between the time when the transport cassette 30(7) is carried into the processing unit 20(W8) and the time when the transport cassette 30(7) is returned to the processing unit 20(W7). This simplifies the process of reading the IC tag 32 in the processing unit 20.

[0030] The control unit 26 also controls the carry-in robot 23i to sequentially remove the disks 5 one by one from the slot 31 of the transport cassette 30(7) and place them in the pocket 21c of the table 21b. In this case, since the control unit 26 controls the carry-in robot 23i, it knows the slot 31 of the transport cassette 30(7) (i.e., the slot number), the table 21b on the turret 21a, and its pocket 21c (i.e., the pocket number). The control unit 26 temporarily stores in the storage unit 25 as carry-in information the cassette information (at the time of carry-in) (the identification information of the IC tag 32, the slot number) and the information associating the pocket number. The delivery information is, for example, Cassette information (at the time of delivery): C7005, S10 Pocket number: P1-1 Information such as:

[0031] (2) Processing information acquisition process The control unit 26 acquires processing information during processing of each disk 5 and stores it temporarily in the storage unit 25. The processing information is, for example, Process type: W8 Pocket number: P1-1 Information such as:

[0032] (3) Carry-out processing The control unit 26 and the reader 22o function as a conveyed member discharge information acquisition unit to acquire conveyed member discharge information. That is, when the disc 5 is removed from the pocket 21c of the polishing device 21, the control unit 26 controls the reader 22o to read the identification information of the IC tag 32 of the transport cassette 30(8). The reader 22o may be configured to read only once when the transport cassette 30(8) is carried into the processing unit 20(W8). In this case, the processing unit 20 can easily read the IC tag 32, as in the carrying-in process.

[0033] Then, the control unit 26 sequentially removes the disks 5 that have been processed in the processing unit 20 one by one from the pocket 21c of the table 21b, and stores them in the slot 31 of the transport cassette 30(8). When all the slots 31 are filled with disks 5, the transport cassette 30(8) is transported to the processing section 20(W9) by a transport device such as a conveyor or a robot, or by a worker.

[0034] Since the control unit 26 controls the unloading robot 23o, it knows the table 21b and its pocket 21c (i.e., pocket number) in which the disk 5 to be removed is stored, and the slot 31 (i.e., slot number) of the transport cassette 30(8). The control unit 26 temporarily stores in the storage unit 25 as carrying-out information the cassette information (at the time of carrying-out) (the identification information of the IC tag 32, the slot number) and the information associating the pocket number. The export information may be, for example, Cassette information (when removed): C8009, S1 Pocket number: P1-1 Information such as:

[0035] After the disc 5 is removed from the pocket 21c, the control unit 26 stores information indicating that the pocket 21c is empty, thereby making the pocket 21c ready to receive a new disc 5.

[0036] (4) Processing record creation process, processing record output process The control unit 26 refers to the storage unit 25 to create a processing record that associates information having the same pocket number among the temporarily stored carry-in information, processing information, and carry-out information. For example, the processing record R8001 has the following information by associating carry-in information, processing information, and carry-out information having the same pocket number P1-1. Cassette information (at the time of delivery): C7005, S10 Cassette information (when removed): C8009, S1 Process type: W8 Pocket number: P1-1 The control unit 26 of the processing unit 20 (W8) outputs (transmits) the created processing record to the management device 40.

[0037] (5) Processing record storage processing When the control unit 46 of the management device 40 receives the processing record output from the processing unit 20, the control unit 46 stores the processing record in the processing record storage unit 45a. For example, the above-mentioned information is stored in the row indicating the processing record R8001 in the processing record storage unit 45a.

[0038] The above processes (1) to (5) are executed by each processing unit 20 each time a disk 5 is loaded, processed, or unloaded. As a result, each time the processing of a disk 5 is completed in each processing unit 20, a processing record is stored in the processing record storage unit 45a.

[0039] As shown in FIG. 4, the cassette information (at the time of unloading) of the processing record R8001 and the cassette information (at the time of loading) of the processing record R9009 are "C8009, S1," which are the same, that is, they are associated information. This indicates the following conditions: The processing unit 20(W8) accommodates the processed disc 5 in the slot 31 assigned with the slot number S1 of the transport cassette 30(8) assigned with the identification information 8009. After this transport cassette 30(8) arrived at the processing unit 20(W9), the processing unit 20(W9) removed and processed the disk 5 accommodated in the slot 31 with slot number S1.

[0040] In this way, the processing record R8001 and the processing record R9009 are associated with each other using the cassette information "C8009, S1" as a key. Similarly, for example, the processing record R1001 of the processing unit 20(W1) and the processing record R2002 of the processing unit 20(W2) are associated with each other using the cassette information "C1001, S2" as a key. This allows the management device 40 to sequentially track other processing records associated with each processing record by referring to the cassette information included in each processing record.

[0041] However, there may be cases where the transport cassettes 30 containing the disks 5 are not transported to the next process in the same order as they were transported out of the previous process. That is, although the processing line processes the disks 5 in a specified order, there may be cases where the line is not continuous, or where multiple processing units 20 are located in different buildings. Furthermore, there may be cases where multiple transport cassettes 30 containing disks 5 are stored between the processing units 20. Furthermore, the ten discs 5 housed in the transport cassette 30(8) may not be housed in the same transport cassette 30(9), but may be housed in multiple transport cassettes 30(9). Even in such a case, in this embodiment, the processing history of the disc 5 can be traced based on the cassette information, so that a database with traceability, which will be described later, can be constructed. Note that disks 5 on the processing line may be rejected or removed from the transport cassette 30 or processing section 20 due to reasons such as jamming or inspection failure. Even for such rejected or removed disks 5, the processing history can be traced based on the cassette information immediately before the rejection or removal. Note that other disks 5 are not affected by the rejected or removed disk 5, and the correspondence of various information is maintained, ensuring traceability.

[0042] (Processing of assembly system 50) The assembly section 60 receives the transport cassette 30(9) from the processing section 20(W9). (1) Carry-in processing The control unit 66 and the reader 62i of the assembly unit 60, like the control unit 26 and the reader 22i of the processing unit 20 (W8), function as a conveyed member carry-in information acquisition unit to acquire conveyed member carry-in information. That is, when the disk 5 is to be removed, the control unit 66 of the assembly unit 60 controls the reader 62i to read the identification information of the IC tag 32 of the transport cassette 30. The control unit 66 also controls the carry-in robot 63i to remove the disks 5 one by one from the slots 31 of the transport cassette 30 and then install them into the HDD 55. Four disks 5 are installed in one HDD 55. Because the control unit 66 controls the carry-in robot 63i, it knows the slots 31 (i.e., slot numbers) of the transport cassette 30(9).

[0043] The control unit 66 temporarily stores the cassette information (at the time of loading) (the identification information of the IC tag 32, the slot number) in the storage unit 65. Cassette information (at the time of delivery) is, for example, C9010, S5 C9010, S9 C9010, S2 C9017, S1 Information such as:

[0044] (2) S / N assignment processing The control unit 66 of the assembly unit 60 assigns a S / N to the HDD 55 after assembly is completed. A method of assigning a S / N to the HDD 55 can be, for example, a method in which an operator attaches a label on which information indicating the S / N (such as a number or code) is pre-printed to the case of the HDD 55. The S / N may be, for example, a one-dimensional code or a two-dimensional code.

[0045] (3) Assembly record creation process, assembly record output process The control unit 66 of the assembly unit 60 performs a process of associating the cassette information (at the time of loading) of the four disks 5 incorporated into the HDD 55 with the S / N assigned to the HDD 55. In this case, the control unit 66 of the assembly unit 60 may track these disks 5 during the assembly process. When assigning S / Ns, the control unit 66 may associate the S / Ns with the cassette information (at the time of loading) of these disks 5.

[0046] As a method for tracking disks 5, for example, if the assembly line is inline and HDDs 55 are assembled in accordance with the order in which disks 5 are removed, the S / N can be associated with the cassette information (at the time of delivery) of these disks 5 in accordance with the order in which the HDDs 55 are completed. Furthermore, the S / N may be obtained by using, for example, a reading device that reads the identification information printed on the label.

[0047] For example, in the example of the assembly record storage unit 75a in Figure 4, when the assembly line starts operating, the disks 5 associated with the cassette information "C9010, S5" are removed first, followed by the disks 5 associated with the cassette information "C9010, S9," "C9010, S2," and "C9017, S1." Even if there are multiple HDDs 55 in the middle of assembly on the assembly line, if the assembly is inline, the first HDD 55 to be assembled will incorporate these four disks 5. Thereafter, the HDDs 55 to be assembled will incorporate four disks 5 at a time in the order in which they were removed from the transport cassette 30(9). This allows the control unit 66 to track the disk 5 removed from the transport cassette 30(9) on the assembly line.

[0048] The control unit 66 then counts the number of disks 5 that have been removed, and associates the count value with the cassette information and temporarily stores the count value in the storage unit 65. When the HDD 55 is completed and an S / N is assigned to the HDD 55, the control unit 66 creates an assembly record that associates information including the S / N (unit information) with the cassette information of the four disks 5. Then, the control unit 66 outputs (transmits) the assembly record to the management device 70.

[0049] (3) Assembly record storage processing When the control unit 76 of the management device 70 receives the assembly record output from the assembling unit 60, the control unit 76 stores the assembly record in the assembly record storage unit 75a. For example, in the assembly record storage unit 75a, the row indicating assembly record RU001 stores information that corresponds the aforementioned cassette information "C9010, S5," "C9010, S9," "C9010, S2," and "9017, S1" to the S / N "U001." Through the above process, every time an HDD 55 is completed in the assembling section 60, an assembly record is stored in the assembly record storage section 75a.

[0050] [Disc 5 Traceability] (Traceability on the processing line (processing history extraction processing)) Here, the disk 5 may be determined as NG (non-conforming product) in various inspections during processing on the processing line, after processing is completed, etc. Also, the disk 5 may be determined as NG due to a defect in any of the multiple pockets 21c. In such a case, the processing system 10 can identify the defective pocket 21c as follows.

[0051] Here, an example will be described in which, after the processing section 20 (W9), which is the final process on the processing line, a robot (not shown) takes out the disks 5 one by one from the slot 31 of the transport cassette 30 (9), and an inspection device (not shown) performs an inspection. Also, an example in which the cassette information of a disk 5 determined to be NG is "C9010, S9" will be described using the example of storage in the processing record storage section 45a shown in FIG. 4. (1) When removing the disk 5 from the transport cassette 30(9), the control unit (not shown) of the inspection device acquires the cassette information "C9010, S9" (key information). The control unit of the inspection device acquires the identification information "C9010" of the IC tag 32 from the reader (not shown) and also acquires the slot number "S9" from the robot. Then, the control unit of the inspection device outputs this cassette information to the management device 40.

[0052] (2) When the control unit 46 of the management device 40 acquires this information from the inspection device, it refers to the processing record storage unit 45a to identify the processing record R9009 associated with the cassette information "C9010, S9" (record identification process). That is, the control unit 46 identifies the processing record R9009 in response to the input of the cassette information "C9010, S9." (3) The control unit 46 refers to the processing record memory unit 45a to read out the processing information "W9, P2-1" and the cassette information (at the time of delivery) "C8009, S1" contained in the processing record R9009 identified in (2) above (record information reading process).

[0053] (4) The control unit 46 refers to the processing record storage unit 45a to identify the processing record R8001 having the same cassette information (at the time of unloading) as the cassette information (at the time of loading) "C8009, S1" read out in (3) above. That is, the control unit 46 uses the cassette information as a key to identify the processing record of the processing unit 20(W8), which is the process preceding the processing unit 20(W9) (previous process processing record identification process). (5) As in (3) above, the control unit 46 reads out the processing information "W8, P1-1" and cassette information (at the time of delivery) "C7005, S10" contained in the processing record R8001 identified in (4) above (previous process processing record information reading process).

[0054] (6) After that, the control unit 46 identifies the processing record R1001 of the processing unit 20 (W1) and repeats the above processes (4) and (5) until it reads out the processing information "W1, P1-1."

[0055] Through the above process, the control unit 46 of the management device 40 can read the processing information "W1, P1-1," "W2, P8-5," ..., "W8, P1-1," and "W9, P2-1" from the processing record storage unit 45a based on the cassette information "C9010, S9" obtained from the inspection device. The disks 5 determined to be NG have a processing history that shows they were stored in these pockets 21c and processed in each processing unit 20.

[0056] Similarly, the management device 40 can also identify the processing history of other disks 5 that have been determined to be NG based on the cassette information acquired from the inspection device. If the processing histories of multiple discs 5 determined to be NG have common processing information, there is a high possibility that the pocket 21c of the processing unit 20 corresponding to that processing information has a defect. For example, if these processing histories have common processing information "W8, P1-1", there is a high possibility that the pocket 21c of the processing unit 20 (W8) with pocket number P1-1 has a defect. This allows the worker to take some measures regarding the pocket 21c (for example, repairing the pocket 21c, not using the pocket 21c during processing, etc.).

[0057] The method for identifying the common processing information is not limited to the above, and various other methods can be used. For example, information about the processing history may be displayed on a display unit (such as a liquid crystal display device) of the management device 40, and the worker may make a judgment by referring to the screen. Furthermore, the control unit 46 of the management device 40 may extract common processing information from the processing histories of multiple discs 5 that have been determined to be NG.

[0058] (Traceability of disk 5 of HDD 55 after assembly (assembly history extraction process)) After the HDD 55 is assembled, the processing history of the disks 5 incorporated into the HDD 55 can be identified based on the S / N through the following process. (1) The control unit 76 of the management device 70 of the assembly system 50 acquires the S / N of the HDD 55 that has been judged as NG by an inspection device (not shown) on the assembly line. The inspection device, for example, performs an operation test on the HDD 55. The method by which the control unit 76 of the management device 70 acquires the S / N (i.e., the method of inputting the S / N) is not limited, and may be, for example, a method in which an operator inputs the S / N indicated on the label into an inspection device using an input device (keyboard, etc.), or a method in which the S / N is read using a reading device. Furthermore, the HDD 55 determined to be NG may be one that has already been shipped, rather than being present in the assembly system 50. In this case, the HDD 55 may be, for example, one that has been withdrawn from the market as a defective product. An example in which the HDD 55 determined to be NG has "S / N: U001" will be described below using examples of storage in the assembly record storage unit 75a and the processing record storage unit 45a shown in FIG.

[0059] (2) When the control unit 76 of the management device 70 of the assembly system 50 acquires the S / N, it refers to the assembly record storage unit 75a to identify the assembly record RU001 having "S / N: U001" (assembly record identification process).The control unit 76 then reads out the cassette information (at the time of delivery) "C9010, S5," "C9010, S9," "C9010, S2," and "C9017, S1" included in the assembly record RU001 (assembly record information read process).

[0060] (3) Thereafter, the management device 40 of the processing system 10 can acquire the cassette information "C9010, S5," "C9010, S9," "C9010, S2," and "C9017, S1," and based thereon, identify the processing history of the disk 5 corresponding to the cassette information, in the same manner as described above (traceability on the processing line). The method by which the management device 40 obtains this cassette information is not limited, and may be, for example, obtained from the management device 70 via the communication network 53, or may be input by an operator into the management device 40 using an input device (such as a keyboard).

[0061] , (4) The management device 40 of the processing system 10 can identify the processing history of the disks 5 for the plurality of HDDs 55 that are determined to be NG based on the cassette information. This allows the management device 40 to identify the pocket 21c in which the disk 5 incorporated in the HDD 55 was processed. Furthermore, even if the HDD 55 determined to be NG contains a non-defective disk 5, the management device 40 can identify the pocket 21c with the most common processing information in the processing history followed by the defective disk 5 as the pocket 21c of the process that is most likely to be the cause of the defect. Furthermore, by identifying the row number in which the defective disk 5 is placed in the HDD 55 that has been judged as NG, it becomes easier to identify the pocket 21c of the process that is likely to be the cause of the defect in the processing history that only the defective disk 5 has followed.

[0062] As described above, the manufacturing system 1 of this embodiment can read the processing history of the disc 5 based on the identification information of the transport cassette 30 and its pocket 21c. This makes it possible to track the manufacturing history of a workpiece even if it is difficult to directly attach identification information to the workpiece by printing, etc. Furthermore, even if multiple transport cassettes 30 are sequentially transported from each processing section 20 and transported to the processing section 20 of the next process in an irregular order due to reasons such as the manufacturing line not being configured inline, the manufacturing history of the workpiece can be tracked.

[0063] (Second embodiment) Next, a second embodiment of the present invention will be described. In the following explanations and drawings, parts that perform the same functions as those in the first embodiment described above will be given similar names as appropriate, and the same symbols or symbols with the same suffix (last two digits) will be given as appropriate, and duplicate explanations will be omitted as appropriate. The manufacturing system according to the first embodiment can be applied to various systems that transport workpieces between processing sections using transport members. In the second embodiment, an example will be described in which the workpiece is a sealing plate 205 to be incorporated into a fuel cell (unit).

[0064] FIG. 5 is a diagram illustrating the overall configuration of a manufacturing system 201 according to the second embodiment. As shown in FIG. 5, the sealing plates 205 are transported between processing sections 220 using a transport cassette 230. The transport cassette 230 has slots 231 each capable of accommodating one sealing plate 205 therein.

[0065] After the sealing plate 205 has lubricating oil applied to it in the processing section 220(W1), it is subjected to punching processing etc. in the processing section 220(W2), the processing section 220(W3), etc., and then transported to the processing section 220(W7). The sealing plate 205 is trimmed at the processing portion 220 (W7). Thereafter, the sealing plate 205 undergoes the cleaning process of the processing section 220(W8) and the processing section 220(W9) and the inspection process, and is then housed in the transport cassette 230(9).

[0066] The sealing plate 205 is shipped to a fuel cell assembly factory in a state housed in a transport cassette 230(9). Then, the fuel cell is assembled using the sealing plate 205 taken out from the transport cassette 230(9) as a component.

[0067] In this way, the manufacturing system 201 transports the sealing plate 205 using the transport cassette 230 when processing the sealing plate 205, and therefore provides the same functions and effects as the first embodiment. Although a detailed description of the fuel cell assembly system will be omitted, similar to the first embodiment, by assigning an S / N to the assembled fuel cell, the system provides the same functions and effects as the first embodiment. The sealing plate 205 may be assembled, for example, to seal the opening at the top of one fuel cell container body (not shown), or may be assembled to seal multiple openings, such as the top and bottom sides.

[0068] Furthermore, an S / N may be assigned to an assembly of multiple fuel cells sealed with one or more sealing plates 205. In this way, if there is an abnormality in the sealing plate 205 of multiple fuel cell assemblies, by referring to the S / Ns of the multiple fuel cell assemblies, it is possible to identify a pocket of processing information with the most common processing information as a possible cause of the defect. Furthermore, if the location of the sealing plate 205 or fuel cell that has an abnormality among multiple fuel cell assemblies is identified, it becomes easier to identify the pocket that is the cause of the defect by referring to the pocket of processing information related to the sealing plate 205 or fuel cell that has an abnormality.

[0069] If the fuel cell product is configured such that the sealing plate 205 is exposed to the outside, the S / N may be marked on the sealing plate 205 by engraving, laser engraving, printing, attaching a label, or the like. In this case, the sealing plate 205, when shipped as a product, may have a marking area for providing the S / N in a later assembly process. In this case, the management device of the assembly system of the assembly line (see management device 70 in FIG. 1) can manage the S / N in association with the identification information and slot number of the transport cassette 230(9) (i.e., cassette information (at the time of loading)) as an assembly record. This allows the assembly system to track the processing history of the sealing plate 205 based on the S / N.

[0070] (Third embodiment) FIG. 6 is a diagram illustrating information stored in the machining record storage unit 345a and the assembly record storage unit 375a according to the third embodiment. The processing record storage unit 345a is similar to the processing record storage unit 45a of the first embodiment. The assembly record storage unit 375a stores an assembly record corresponding to each disk. That is, the assembly record storage unit 375a stores four assembly records (R001-1 to R001-4, etc.) for one HDD. Each assembly record contains information that associates cassette information (at the time of delivery), S / N, and disk number.

[0071] Disk numbers D1 to D4 are information corresponding to the number of rows in which four disks are arranged within the HDD. In other words, the disk numbers are identification information for the arrangement areas in which the disks are arranged. Disk numbers D1 to D4 are set in descending order by one row, with disk number D1 being the arrangement area in the top row and disk number D4 being the arrangement area in the bottom row.

[0072] Here, the control unit of the assembly unit (see control unit 66 in Figure 3) controls the loading robot (see loading robot 63i in Figure 3), so when installing each disk into the HDD, it can grasp the slot number of the transport cassette and the disk number in the HDD. Therefore, when assembling the HDD, the control unit of the assembly unit can create information (unit information) that associates the S / N (unit identification information) of the HDD into which each disk is to be installed with the disk number of each disk.

[0073] Then, the control unit of the assembly unit creates an assembly record and transmits it to the management device of the assembly system (see management device 70 in FIG. 1). For example, assembly record RU001-2 is information in which cassette information (at the time of delivery) "C9010, S9", S / N "U001", and disk number "D2" are associated.

[0074] When the management device of the assembly system receives the assembly record, it stores it in the assembly record storage unit 375a. This allows the manufacturing system of this embodiment to manage each disk incorporated into the HDD individually.

[0075] Furthermore, in the manufacturing system of this embodiment, if, for example, one of the disks in an assembled HDD is defective, the manufacturing history of that disk can be tracked individually. That is, the management device of the manufacturing system or assembly system can track the manufacturing history of that disk by referring to the manufacturing record storage unit 345a and the assembly record storage unit 375a in response to input of information (unit information) including the HDD S / N and the disk number where that disk is located. For example, the thick lines in FIG. 6 indicate a manner in which the processing history of S / N "U001" and disk number "D2" is traced back to cassette information (at the time of loading) and cassette information (at the time of unloading).

[0076] Although the embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments, and various modifications and variations, such as the modified embodiments described below, are possible, and these are also within the technical scope of the present invention. Furthermore, the effects described in the embodiments are merely a list of the most preferable effects resulting from the present invention, and the effects of the present invention are not limited to those described in the embodiments. Note that the configurations of the above-described embodiments and the modified embodiments described below can be used only in part, or in appropriate combination, and detailed description thereof will be omitted.

[0077] (Variations) (1) In the embodiment, the processing line management device and the assembly department management device are separate devices, but this is not limiting. The processing line management device and the assembly department management device may be integrated into one device. In this case, for example, the processing line management device may communicate with the assembly department to obtain the assembly record from the assembly department.

[0078] (2) In the embodiment, an example in which the management device of the processing line and the management device of the assembly department execute the traceability process has been described, but this is not limiting. For example, the information in the processing record storage unit and the information in the assembly record storage unit may be copied (duplicated) to another computer, etc., and this computer may execute the traceability process.

[0079] (3) In the embodiment, an example in which a reader reads information from an IC tag of a transport cassette has been described, but this is not limiting. For example, a reader / writer may read information from an IC tag of a transport cassette. In this case, the reader / writer may rewrite the identification information in the IC tag when the transport cassette is transported to each processing unit.

[0080] (4) In the embodiment, the S / N is attached to the unit in which the workpiece is incorporated, but this is not limiting. The S / N may be attached to the workpiece itself, for example, depending on the shape of the workpiece.

[0081] (5) In the embodiment, an example has been shown in which the IC tag is rewritable, but this is not limiting. The IC tag may also be non-rewritable. In this case, information on the date and time when the transport member is transported out of the processing unit and information on the date and time when the transport member is transported into the processing unit can be added to the cassette information (at the time of transport out) and the cassette information (at the time of transport in). In this case, in the processing history extraction process, etc., the processing history of the workpiece can be extracted by associating the cassette information (at the time of transport out) and the cassette information (at the time of transport in) that have similar date and time information. Alternatively, instead of the IC tag of the transport cassette 30, 230, an identification mark such as letters, figures, or codes may be engraved, printed, or labeled on the transport cassette 30 itself, and the control unit 46 may store the identification mark of the transport cassette 30, 230 in the processing record storage unit, for example, along with date and time information. In this case, the readers 22i, 22o, 62i may capture an image of the identification mark with a camera or the like and identify and read the image as letters, figures, or codes.

[0082] (6) In the embodiment, the transport cassette 30, 230 may be moved from upstream (the first-step processing section 20, 220) to downstream (such as the downstream processing section 20, 220 or the assembly section 60) and then transported back in from the upstream (the first-step processing section 20, 220) instead of traveling back and forth between the processing sections 20, 220 or between the processing section 20 and the assembly section 60. Also, the transport cassette 30, 230 may be used for one transport from the upstream processing section 20, 220 to the downstream processing section 20, 220 or the assembly section 60, and then a new transport cassette 30, 230 may be used.

[0083] (7) In the embodiment, an example is shown in which the workpiece is sequentially transported to processing units with different types of processing content, but this is not limiting. The workpiece may be processed only in a processing unit with one type of processing content. In this case, the management device acquires the identification information of the output cassette that exports the workpiece from the processing section, the slot number of the output cassette (identification information of the storage section), and the processing record (information that associates the processing information at the processing section with the transport member export information acquired by the transport member export information acquisition section) without using the transport member import information, and by associating and managing these, it is possible to achieve traceability of the processing history of the workpiece.
