Description

  The present invention relates to a member product information recording apparatus, a member product information recording method, and a member product information used for managing traceability information of parts or materials (hereinafter referred to as member products) constituting an industrial product (hereinafter referred to as a manufactured product). The present invention relates to a recording program and a member information recording program storage medium.

  2. Description of the Related Art Conventionally, many manufactured products are given a product name, a manufacturer name, a manufacturing serial number, or a manufacturing lot number as information that is the basis of the origin and manufacturing history. Among them, the manufacturing serial number or the manufacturing lot number is important information indicating the traceability of the manufacturing history of the manufactured product.

  For example, when a quality problem such as a defect in a manufactured product shipped to the market occurs, the manufacturer that manufactured the manufactured product is related to the date of manufacture from the manufacturing serial number or manufacturing lot number By determining the manufacturing equipment and the like, the cause of the failure can be investigated. In addition, for manufactured products that are judged to have the same manufacturing history as the manufactured product that has a defect from the manufacturing serial number or manufacturing lot number, measures such as sales prohibition or collection from the market can be taken. Can be prevented from expanding.

  However, in order to determine the manufacturing date and related manufacturing equipment from the manufacturing serial number or manufacturing lot number, or to determine that the manufacturing history is the same, the manufacturer must It is necessary to record traceability information for identifying the manufacturing history for each one in a document or database. The basic information in the traceability information is information on what kind of component the manufactured product is composed of, and further is individual identification information of the component that is actually used. In other words, the basic traceability information is a so-called bill of materials (BOM), which is the name / model and the manufacturing serial number or the manufacturing lot number of each part for each manufactured product.

  In general, manufacturers record and manage the names and types of parts used for each manufactured product in a database (parts table database or the like). Furthermore, a manufacturing serial number or a manufacturing lot number is assigned to each manufactured product, and the manufactured product is actually configured for a manufactured product with the manufacturing serial number or manufacturing lot number. The production serial number or production lot number of the component parts being recorded is recorded and managed in a database (manufacturing performance information database, etc.). When a quality problem such as that described above occurs, a predetermined response such as determining a manufactured product related to the quality problem is performed by using these databases.

  However, even if such databases are stored, in reality, there may be inconveniences due to insufficient management of these databases. For example, in order to improve the performance and the like of a manufactured product, the parts used at the manufacturing site are often changed. In such a case, even if the so-called manufacturing instruction is changed, the bill of materials is changed. The database of information may not change. If this situation is overlooked, there will be a difference between the components recorded in the parts table information database and the components actually used. In such a case, a defect or the like occurs in the manufactured product, and inconvenience may occur when trying to investigate the cause.

  Some manufactured products are used for more than 10 years, 15 years or more, and in some cases 25 years or more, exceeding the shelf life (for example, 7 years, 10 years, etc.). There is. The database for such manufactured products needs to be kept for the period. However, in reality, when the computer storing the database is replaced or software for managing the database is changed, a situation in which the database cannot be actually used even when the database is stored often occurs. In such a case, traceability information on the manufacturing history of the manufactured product does not exist.

  To avoid this situation, every time you replace a computer or change management software, you can change the old database to match the new one, but it is not manufactured and sold. In reality, a database of manufactured products that have not been stored or whose component products have been stored for a long time tends to remain unchangeable.

  By the way, in recent years, a non-contact individual identification technique using an IC (Integrated Circuits) tag (also called an RFID (Radio Frequency Identification) tag) has been put into practical use and has begun to be applied in various fields. Here, the IC tag is an IC chip with an antenna, and the IC chip is provided with a non-volatile memory and communication means using weak radio waves, and externally to the non-volatile memory via the communication means. Information can be read and written. In general, the IC tag is often written with individual identification information of an article to which the IC tag is attached.

For example, in Patent Document 1, an IC tag is attached to a member product in a manufacturing process, and information on a parent member product to which the member product is attached is written in the IC tag. Write the information of this component to be attached, and check the information written in each IC tag when attaching the child component to the parent component, so that the child component is the wrong parent. An example of a manufacturing system for preventing attachment to a component is disclosed.
JP 2005-35327 A (paragraph 0015, paragraph 0016, FIGS. 1 and 2)

  In the manufacturing system disclosed in Patent Document 1, although an IC tag is effectively used to prevent an error in assembling a member, information written in the IC tag is exclusively the name of the member. It is information indicating a model and the like, and is not identification information for individually identifying a member product. Therefore, the manufacturing system disclosed in Patent Document 1 does not include an intention to apply the IC tag to solve the problems of the related art relating to the traceability information of the manufactured product.

  Here, as described above, the problem of the related art relating to the traceability information of manufactured products is different from the database in which the traceability information of manufactured products including information on parts lists is actually manufactured. Or being unusable on a computer that can run at that time.

  An object of the present invention is to make it possible to avoid storing a database such as a parts table database for a manufactured product or a manufacturing performance information database in which individual identification information of components constituting the manufactured product is recorded in a computer. . Instead, a member product information recording apparatus, a member product information recording method, and a member product capable of recording information corresponding to such information on an IC tag attached to each manufactured product in the manufacturing process of the manufactured product. An object is to provide an information recording program and a member information recording program storage medium.

  In order to solve the above-described problems, the member product information recording apparatus of the present invention includes a plurality of member product storage units that store a plurality of member products, respectively, and is stored in the plurality of member product storage units, respectively. A base member that is used by being connected to a member assembly apparatus that takes out a predetermined number of member products from the member product, assembles the extracted member products, and manufactures a predetermined manufactured product, and serves as a base of the manufactured product among the member products It is configured as a member product information recording device for writing individual identification information relating to a member product constituting the manufactured product to an IC tag attached to the product. Then, the member product information recording device is provided with an IC tag attached to the member product when the member product assembly device takes out the member product used for assembly from the member product storage unit, or the member product. A member product information reading means for reading individual identification information related to the member product from an IC tag attached to the member product storage unit where the product has been stored, and a member product taken out from the member product storage unit by the member product assembly device Is the base member product, the individual identification information related to the manufactured product and the acquired individual identification information related to the base member product are written on the IC tag attached to the base member product, and the member product assembly apparatus When the member product taken out from the member product storage unit is not a base member product, individual identification information related to the member product is written on an IC tag attached to the base member product on which the member product is mounted. Characterized in that it is configured to include a non-member item information writing means.

  That is, in the present invention, not only the individual identification information of the base member product but also the individual identification information of the mounted member product mounted on the base member product is recorded on the IC tag attached to the base member product. Here, the individual identification information of the member product usually means the production serial number or production lot number of the component product including the name and model of the component product, and the IC tag attached to the base member product has its Manufacturing history information about the manufactured product is recorded. Therefore, in the present invention, by reading the information recorded on the IC tag attached to the base member product of the manufactured product, what kind of member product is included in the manufactured product (information on the parts table) In addition, it is possible to easily know information (manufacturing serial number or manufacturing lot number) indicating what manufacturing history information the component has.

  Therefore, neither the parts table database of the manufactured product nor the database for recording the individual identification information of the component parts constituting the manufactured product for each manufactured product becomes unnecessary. Therefore, the database that records the traceability information of the manufactured product including the information on the parts table may be different from the database that is actually manufactured, or may not be available on the computer that can be operated at that time. As a result, the above-mentioned problems of the prior art are solved.

  According to the present invention, it is not necessary to store in a computer a database such as a parts list database of manufactured products and a manufacturing performance information database in which individual identification information of component parts constituting the manufactured products is recorded.

Is loaded into the storage unit 34 of the component information recording apparatus 3.

  Although not shown in the figure, the configuration of the component delivery slip information input terminal 4 is almost the same as the configuration of the component information recording apparatus 3. The difference is that the barcode reader 41 is used instead of the IC tag reader / writer B31, and the IC tag reader / writer A41 is used instead of the IC tag reader / writer C32. The programs stored in the storage unit are different. .

  Hereinafter, a procedure for writing information on the mounting member product 8 to the IC tag 71 attached to the base member product 7 in the present embodiment will be described in detail.

  FIG. 4 is a diagram showing a work procedure of an operator when taking out purchased parts from a packing case and refilling them into a transfer case, and a process flow of the parts delivery slip information input terminal.

  Normally, in a factory that manufactures manufactured products by assembling and processing purchased parts, when an operator accepts delivery of the purchased parts (MS1), the purchased parts packing case 9 is unpacked and delivered. Delivery inspection is performed for the parts (MS2). In some cases, the delivery inspection may be performed simply by confirming the item or quantity, and in some cases, the function or performance may be inspected using a predetermined inspection apparatus, either of which may be used here. Then, the worker refills the parts that have passed the delivery inspection into the transfer case 23 (MS3). In addition, you may make it the purchase member goods packing case 9 serve as the transfer case 23, and the operation | work which refills a member goods to the transfer case 23 in this case can be abbreviate | omitted.

  In addition, the worker reads the member information recorded on the barcode 91 attached to the purchased component packing case 9 with respect to the member that has passed the delivery inspection by the barcode reader 41, and the member delivery slip The information is input to the information input terminal 4. Further, when the member product information is described in the delivery slip 92 instead of the barcode 91, the worker inputs the information to the member product delivery slip information input terminal 4 by using a keyboard or the like. In addition, the part product information here is the order number related to the delivered part product, the part product name (the product product name shall include the model name, etc.), the production lot number (or production serial number), and the number of products received. Information.

  That is, the member delivery slip information input terminal 4 inputs the member information related to the delivered member recorded in the barcode 91 or the like by the barcode reader 41 or the like (step S11). The member delivery slip information input terminal 4 adds the member information input from the barcode 91 or the like to the transfer case 23 when the member passed the delivery inspection is refilled in the transfer case 23. Is written in the IC tag 231 (step S12). At this time, the number of parts received in the part information is replaced with the number of parts transferred by the transfer case 23.

  In addition, when a member product such as a semiconductor component is small or produced in units of lots, it is common that a production lot number is assigned to the member product. On the other hand, for example, when the size of the member product is large as in the case of the base member product 7 or when the member product is already mounted with another member product, the member product is usually at least the manufacturer. A production serial number that can be identified individually is attached. Such a production serial number is often directly written in characters or a barcode on a part of a member. Therefore, in such a case, in this embodiment, an IC tag in which a member product name and a manufacturing serial number of the member product are attached is attached to the member product (for example, the base member product 7). . This work can be performed by the worker using the member delivery slip information input terminal 4, but may be performed using a special machine such as an IC tag sticking device.

  Next, the member product refilled in the transfer case 23 is transferred to the member product assembling apparatus 2 and further transferred to the member product storage unit 22 as shown in FIG. At this time, the information written in the IC tag 231 of the transfer case 23 is written in the IC tag 221 of the member product storage unit 22 as it is. In this case, the IC tag 231 of the transfer case 23 may be transferred to the member product storage unit 22 at the same time as the member product, and may be used as the IC tag 221 of the member product storage unit 22. In addition, if the transfer case 23 can be used as the member product storage unit 22, the work of transferring the member product from the transfer case 23 to the member product storage unit 22 can be omitted.

  FIG. 5 is a diagram showing a processing flow of the member product information recording device when the member product assembly device assembles the member product. Here, it is assumed that a predetermined number of base member products 7 and mounting member products 8 are respectively set in the member product storage unit 22. First, for example, the robot arm of the member product assembly unit 21 takes out one base member product 7 from the member product storage unit 22 and sets the taken base member product 7 in a predetermined place of the member product assembly device 2. (MS5).

  Here, when the robot arm takes out the base member product 7 from the member product storage unit 22 via the IC tag reader / writer B31, the member product information recording apparatus 3 uses the base member product 7 from the IC tag 71 of the base member product 7, for example. The member product information (base member product name and base member product identification number: the member product identification number indicates the manufacturing lot number or the manufacturing serial number) is read (step S21). Then, the component information recording device 3 acquires the parts table of the manufactured product from the parts table DB 51 of the parts table management server device 5 (step S22). At this time, it is assumed that the manufactured product name of the manufactured product assembled and manufactured by the member product assembling apparatus 2 has already been input to the member product information recording device 3. Next, the member product information recording apparatus 3 sends the product product information (product product name and product product identification number), substrate member product information (substrate member product name and substrate member product identification number), and the IC tag reader / writer C32. The parts table information is written into the IC tag 71 of the base member product 7 (step S23).

  Subsequently, for example, the robot arm of the member assembly unit 21 takes out a predetermined number of the mounted member products 8 from the member storage unit 22 and mounts the removed mounted member products 8 in a predetermined place of the base member product 7. (MS6). Here, for example, when the robot arm takes out the mounted member product 8 from the member product storage unit 22 via the IC tag reader / writer B31, the member product information recording device 3 starts from the IC tag 221 of the member product storage unit 22. The mounted member product information (mounted member product name and mounted member product identification number) is read (step S24). Next, when the robot arm mounts the mounting member product 8 on the base member product 7, the member product information recording device 3 receives the mounting member product information (the mounting member product name and the mounting member product identification number) via the IC tag reader / writer 32. ) Is added to the IC tag 71 of the base member product 7 (step S25). Further, the member product information recording apparatus 3 continues the processing of step S24 and step S25 until the mounting of the mounting member product 8 on the base member product 7 by the robot arm or the like (MS6) is completed (step S26).

  Here, the processing of step S21 and step S24 corresponds to the processing when the program of the member information reading processing unit 341 (see FIG. 3) is executed, and the processing of step S23 and step S25 is the writing of member information. This corresponds to the processing when the program of the processing unit 342 is executed. Step S22 corresponds to the processing when the parts table information acquisition processing unit 344 is executed.

  FIG. 6 is an example of a recording format of member product information to be written in the IC tag of the base member product. First, the manufactured product name and the manufactured product identification number are recorded on the IC tag 71 of the base member product 7, and then the base member product name and the base member product identification number are recorded. Here, the name of the manufactured product refers to the name of the manufactured product manufactured by mounting the mounting member product 8 on the base member product 7 and is, for example, “ABC personal computer motherboard / M3 type”. The base member product name is, for example, the name of a printed circuit board on which a member product such as an integrated circuit chip is not mounted, and is, for example, “motherboard printed circuit board / ABC1 type”. Further, the name of the mounted member product, the number of mounted member products, and the mounted member product identification number are recorded. The number of mounted member product identification numbers is recorded after the number of mounted member products.

  In FIG. 6, the data length of each item of information written to the IC tag 71 may be fixed, and the information of each recording item is separated by a delimiter such as a CR (Carriage Return) character. Also good. Then, for example, the information recording is terminated by a null character.

  As described above, in the present embodiment, the parts table and the members related to the member product constituting the manufactured product manufactured by mounting the mounting member product 8 on the base member product 7 to the IC tag 71 of the base member product 7. Product information will be recorded. Therefore, it is not necessary to store the parts table information related to the manufactured product and the member information about each manufactured product as a database. Further, the member product information recorded on the IC tag 71 in this embodiment is recorded while the mounting member product 8 is mounted on the base member product 7 by the member product assembling apparatus 2. Therefore, there is no discrepancy between the information in the parts table obtained from the component information recorded in the IC tag 71 and the component item names of the component items constituting the component table information.

  Note that the member product information written in the IC tag 71 in FIG. 6 may be encrypted information in order to prevent a third party from reading and misusing it. In this case, when the member information recording apparatus 3 writes the member information to the IC tag 71, the member information to be written is encrypted by a predetermined encryption method, and the encrypted information is written to the IC tag 71. Like that. Further, the process of step S25 in FIG. 5 does not simply add the mounted member product information, but once the member product information in the format of FIG. 6 is formed for all information to be recorded, the member product information is After encryption, the data is written into the IC tag 71.

  FIG. 7 is a diagram schematically showing an example in which member product information is written in an IC tag of a base member product in the case where manufactured product components are assembled hierarchically. In FIG. 7, first, a member A having a member name of D001 is mounted on a printed circuit board having a member name of C001, and a function A board having a manufactured item name of A001 is manufactured. Produces a B001 functional B board. In this case, when the IC tag of the printed circuit board having the member product name C001 is stored in the member product storage unit 22, only the member product name C001 of the printed circuit board and the member product identification number 123456 are recorded. When the printed circuit board is set in the component assembling apparatus 2, the IC tag has a product name A001 as a function A board, a product identification number A000001, and a bill of material information (a product with the product name A001). (Refer to TG1 in the column of the member product information recorded in the IC tag). At this time, since it is known that the base member product name is C001, the member product identification number is 123456, the information is also written.

  Next, when the mounting of the predetermined mounting member product is finished on the printed circuit board having the member product name C001 and the function A board (manufactured product name A001, manufactured product identification number A000001) is manufactured, the base member product (member product) The IC tag of the printed circuit board having the name C001) has a bill of material information and a member product information (a member product name and a member product identification number) for all the member products constituting the function A board of the manufactured product name A001 and the manufactured product identification number A000001. ) Is written (see TG2). Further, the same information is also written in the IC tag for the separately manufactured function B board (manufactured product name B001, manufactured product identification number B000001) (see TG3).

  Next, when the function A board (manufactured product name A001) and the function B board (manufactured product name B001) are put into the chassis (member product name KK01) to manufacture the XX device (manufactured product name K001), Member product information as shown in TG4 is written in the IC tag attached to the chassis, which is a base member product. Further, when two similarly manufactured XX devices (manufactured product name K001) are docked to produce a dual XX device (manufactured product name L001), the chassis of either XX device (which is the base member) The member tag information as shown in TG5 is written in the IC tag attached to the tag.

  FIG. 8 is a diagram schematically showing an example of member product information written on an IC tag attached to a base member product in each layer for a manufactured product in which the member products are hierarchically assembled. In FIG. 8, TG5 is an example of member information written on an IC tag attached to a dual OO device (manufactured product name L001, manufactured product identification number L000003), and TG4 is an example of XX device ( It is an example of the member product information attached | subjected to the manufactured product name K001 and the manufactured product identification number K000003).

Other embodiments such as the apparatus configuration and processing procedure are the same as the above-described embodiments. In such a case, for example, for the manufactured product shown in the example of FIG. 8, the member product information written in the IC tag 71 of the base member product 7 in each layer is information as shown in FIG.

  As can be seen from FIG. 9, even if there is no information on the parts table and there is no name of the component part, not only the structure of the component part but also the information on the hierarchical structure of the component part is obtained for the manufactured product. be able to. In this case, however, it is often insufficient to use only the manufacturing lot number or the manufacturing serial number as the component identification information. This is because the manufacturing lot number or the manufacturing serial number assigned to the component is not known by the manufacturer that manufactured the component, and the name of the component cannot be known or cannot be individually identified. However, in this case, in addition to the manufacturing lot number or the manufacturing serial number, the name of the manufacturer of the member product and the name / model of the member product may be included as the member product identification information.

  Further, as a modified example of another embodiment, as information accompanying the member product identification information, manufacturing history information of the member product, for example, a manufacturing device name, a manufacturing date, an inspection device name of the member product, etc. Information may be recorded on the IC tag 71 of the base member product 7. Further, attribute information as an article of the member product, for example, information such as size, color, weight, and performance may be recorded in the IC tag 71.
