Description

  The present invention relates to a repair support system, a repair support method, a repair support program, and a repair support program for assisting in efficiently performing repair work by predicting a repair spot when repairing a product and clearly indicating the repair spot to a repair person. The present invention relates to a recording medium that stores.

  As a conventional technique related to the present invention, there is a repair support system described below (see, for example, Patent Document 1).

When a defective item is input, this repair support system extracts a repair location for the defective item from a database storing inspection results and a repair history, selects the repair location in descending order, and estimates a repair location. The repair person performs repair based on the repair point presented by the system. If the re-inspection after repair is OK, the repair location is stored in the repair history database. However, if the re-inspection after repair is NG, the repair location is not stored in the repair history database. By performing the above data processing, it is possible to estimate the repaired part of the product without depending on the experience of the repairer.
JP-A-2005-190026

  However, in the above-described conventional repair support system, when a defect occurs in the inspection after assembling the product, there are cases where repair is immediately started and repair is not performed depending on the defect phenomenon. In the case of home appliances, the former has an appearance defect such as a scratch, and in this case, repair work such as replacement or repair of a defective appearance part can be performed immediately. Further, after mounting the components on the printed circuit board, an inspection by an ICT (In-Circuit Tester) is performed, the defective portion is output from the ICT, and the defective portion indicated by the ICT is repaired.

  However, if the inspection result after product assembly is defective such as functional defect or lack of performance, there are various causes, so it is difficult to identify the repaired part, and traditional experienced repairers, In many cases, quality managers or designers specify repair points. In addition, as a result of reviewing production conditions and improving design after occurrence of defects, there are cases where process quality is worsened rather than improved, and it is becoming more difficult to specify a repaired part.

  The repair support system described in Patent Document 1 estimates a repair location with a greater number of repairs than past repair data, but is sufficient for such defects as functional defects and lack of performance as described above. There was a problem that it was not applicable. Further, the repair support system of Patent Document 1 is based on the assumption that there is past repair data, and there is no defective item in the inspection database that is the same as that generated in the past, or the repair location for the defective item is the repair database. Since the data cannot be processed when there is no such data, there is a problem that repair data cannot be accumulated for a new defect. In addition, in connection with such problems, there has been a demand for visual indication of repair history and repair locations so that anyone can understand them.

  The present invention was devised to solve such problems, and the purpose of the present invention is to provide a repair support system that improves the efficiency of repair by allowing the repair location to be understood at a glance without degrading the process quality.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  FIG. 1 is a system configuration diagram of a repair support system according to the present embodiment.

  The repair support system according to the present embodiment can be broadly classified into an inspection data collection unit A that collects inspection data in the inspection process, and a repair support unit B that collects repair data by clearly indicating the repair location in the repair process to the repair person. , And a network C for transmitting and receiving data between elements constituting the system.

  The inspection data collection unit A includes a recording medium 1, a first storage medium reading unit 3, an inspection data processing unit 4, and an inspection database 5.

  The recording medium 1 is mounted for each product 2, and in order to track the inspection result and repair data history of the mounted product 2, the model name and serial number of the product are recorded in advance. As such a recording medium 1, a barcode, a two-dimensional code, an IC tag, an RFID, or the like can be used. FIG. 2 shows a sample example of the recording medium 1, and here, a barcode is illustrated.

  The first recording medium reading unit 3 is a device that reads information on the recording medium 1, and a barcode reader is used when reading the barcode of FIG. 2.

  The inspection data processing unit 4 is a data processing unit for associating the model name and manufacturing number read by the first recording medium reading unit 3 with the inspection result for each product 2 in the inspection database 5. FIG. 3 shows an example of the structure of the inspection database 5.

  The inspection database 5 includes items of inspection date / time, model name, serial number, inspection result, and defective items. The model name and the serial number can be acquired by reading the recording medium 1 with the first storage medium reading unit 3, and the inspection date is the date when the storage medium 1 is read. The inspection result is a determination result of OK (non-defective product) or NG (defective product) for each product 2 by an inspection device or a person. The inspection result is stored together with the model name, serial number, inspection date and time, and defective items in the case of NG.

  The inspection data processing unit 4 writes the result of re-inspection after product repair into the repair database 13 and performs data update processing for tracking the repair history. The data update process will be described in detail in step S16 described later.

  The repair support unit B includes a second recording medium reading unit 6, a defective item selection unit 7, a repair history search unit 8, a repair location prediction unit 9, a repair location display unit 10, a repair location input unit 11, and a repair location registration unit 12. , A repair history database 13 and a CAD database 14. After inspecting each product 2, the product 2 is sent to a repair process in which the repair support unit B is arranged with the recording medium 1 mounted. Hereinafter, the repair support unit B will be described.

  Since the model name and the serial number are recorded in the recording medium 1 mounted on the product 2, the model name and the product name to be repaired are read by reading the recording medium 1 with the second recording medium reading unit 6. Know the serial number.

  The defective item selection unit 7 can select and input the defective item by searching for and displaying the defective item from the inspection database 5 using the model name and manufacturing number obtained from the second recording medium reading unit 6 as search keys. It has become.

  The repair history search unit 8 searches the repair history database 13 for the repair history stored in the repair history database 13 for each product 2 to obtain the repair location and the reinspection result.

  The repair location prediction unit 9 excludes a repair location for which the re-inspection result obtained by the repair history search unit 8 is NG from the target of prediction, and then uses the model name and the defective item as a key for the repair history database 13. The number of repairs is calculated by repair location and repair date, and the repair location is predicted based on the trend of the results. Details of the prediction method will be described in detail in step 10 described later.

  The repair location display unit 10 retrieves information necessary for drawing an exploded view from the CAD database 14 using the model name as a key, draws an exploded view, and shows the repair location predicted by the repair location prediction unit 9 in the exploded view. Highlight above. In addition, the repair history for each product 2 is displayed together with the exploded view, and the repair is performed. However, the result of the re-inspection is NG, and the repair location to be excluded from the repair target is presented.

  The repair location input unit 11 is used to select and input a repair location from the exploded view drawn on the repair location display unit 10 when the repair location cannot be predicted.

  The repair location registration unit 11 registers the repair location in the repair history database 13. If the repair location can be predicted, the repair location predicted by the repair location prediction unit 9 is registered in the repair history database 13. If the repair location cannot be predicted, the repair location selected and input by the repair location input unit 10 is registered in the repair history database 13. .

  FIG. 4 shows an example of the structure of the repair history database 13.

  The repair history database 13 includes defect items and inspection dates and times as defect information, repair locations and repair dates and times as repair information, and these defect information and repair information are stored for each model and each manufacturing number. The repair history database 13 also stores a re-inspection date and time and a re-inspection result after repair so that the repair history can be easily understood.

  The CAD database 14 stores information necessary for drawing an exploded view for each model. Hereinafter, it will be described in detail with reference to a configuration example of the CAD database 14 shown in FIG. 5 and an explanatory diagram of line segment coordinates shown in FIG.

  In the present embodiment, in order to draw the parts and the part numbers constituting the product 2, the parts are expressed as an assembly of a plurality of planes, and the plane is approximated as a closed polygon, that is, an assembly of line segments, The part number is treated as a character and stored in the CAD database 14 in the form shown in FIG. That is, a part number, a part name, a display color of the part, a part number, a character size for drawing the part name, and a character type are stored as part information. Since the part is approximated as an assembly of a plurality of planes, a display color is stored for each surface constituting the part. In addition, the polygon information includes line segment coordinates for drawing a plane, line color and thickness information, and the line segment coordinates such as X1, Y1, X2, Y2,. The origin of the exploded view is used as the origin of coordinates.

  Parts information and polygon information are retrieved and acquired from the CAD database 14 shown in FIG. 5 using the model name as a key, and an exploded view is drawn. The rendered exploded view is shown in FIG.

  Regarding the component information, the component on the exploded view can be highlighted by changing the display color of the component, the character size, the character type, or the thickness of the line segment. For example, by drawing a component diagram with the component display color set to “red”, the character size set to “14”, the character type set to “bold”, or the line segment thickness set to “2 pt”, Parts can be highlighted. Conversely, by setting the display color of a part as “gray”, it is possible to draw a part that is desired to be excluded from the repair target.

  Next, data processing at the time of repair support by the repair support system having the above configuration will be described with reference to the flowchart shown in FIG.

  In step S1, the storage medium 1 attached to the product 2 is read by the second recording medium reading unit 6, and the model name and the serial number are acquired.

  In step S2, after the inspection of the product 2, the inspection result and the defective item are stored in the inspection database 5 together with the model name, the manufacturing number, and the inspection date and time acquired in step S1.

  In step S3, judging from the inspection result, if it is OK (that is, if there is no NG in the search result), the data processing is terminated.

  In step S4, if the inspection result is NG in step S3, it is determined whether or not re-inspection is performed. That is, when there are a plurality of records having the same model, serial number, and defective item in the inspection database 12, if the inspection date is the latest inspection data and the inspection result is NG in these records, The processing in step S16 is performed assuming that the defect is due to re-inspection after repair. On the other hand, if it is not re-inspection, the process of step S5 is performed.

  In step S5, the recording medium 1 mounted on the product 2 in the repair process is read by the second recording medium reading unit 6, and the model name and the serial number are acquired.

  In step S6, a defective item is searched from the inspection database 5 and displayed using the model name and manufacturing number acquired in step S5 as keys. Then, a defective item is selected from the displayed defective items. For example, in the case of the model name “MODELA” and the production number “X0004”, “white line by copying” is selected as the defective item.

  In step S7, a repair location and a re-inspection result are searched from the repair history database 13 using the model name, serial number, and defective item in step S6 as keys.

  In step S8, information necessary for drawing an exploded view is retrieved from the CAD database 13 using the model name as a key, and the exploded view is drawn.

  In step S9, it is determined whether there is a repair location. That is, since the repair location is known from the search result of the repair location in step S7, the presence or absence of the repair location can be determined.

  In step S10, a repair location is predicted when there is a repair location in step S9. That is, using the model name obtained in step S5 and the defective item selected in step S6 as a search key, data matching the search key is searched from the repair history database 13, and the number of repairs is totaled by repair location and repair date. To do.

  FIG. 9 shows an example of the total result. In this example, the repair date is plotted on the horizontal axis, the number of repairs is plotted on the vertical axis, and the trend is plotted on the graph with the repair location as a parameter. And the number of repairs is predicted by extrapolating the trend of repairs by repair location. In the example shown in FIG. 9A, since the number of repairs of the part A is the largest, it is predicted that the part A is a repair location. On the other hand, in the example shown in FIG. 9B, the number of repairs of the part A has been large in the past, but it is decreasing, and conversely, the part C is increasing. Therefore, in this case, the part C is predicted to be a repaired part.

  In step S11, attribute data such as the repair location predicted in step S10, that is, the display color of the component, the thickness and color of the line segment for drawing the component diagram, and the character size and thickness of the component number are set.

  In step S12, the repair location is highlighted on the exploded view based on the data set in step S11.

  FIG. 10 is an example in which a repair location is highlighted. In this example, the part D with the part number 1 is highlighted as a repair location. Therefore, the repair person can start repairing the highlighted part D. In addition, when repair is performed on the part B but the result of the re-inspection is NG, the part B is displayed in gray so that the part B is excluded from the repair target (in FIG. Attached).

  In step S13, if it is determined in step S9 that there is no repair location, a repair location is selected from the exploded view drawn in step S8. That is, the exploded view drawn in step S8 is drawn on the repair location display unit 10 such as a graphic display, and the repair person is drawn on the repair location display unit 10 using the repair location input unit 11 such as a mouse or a doublet. Select the repair location from the exploded view.

  In step S14, the repair location highlighted in step S12 or the repair location selected in step S13 is registered in the repair history database 13. That is, the model name and serial number obtained in step S3, the defective item selected in step S4, the repair location and repair date predicted in step S10, and the test date and time obtained from the test database 5 are as follows: Store in the repair history database 13. In this case, no information is stored in the reinspection date / time and reinspection result columns of the repair history database 13.

  In step S15, the repair person performs the repair work of the repair spot highlighted in step S12 or the repair spot selected in step S13. After the repair work is completed, the repaired product 2 is returned to the inspection process, and step S1 is performed. Is performed. That is, a process of reading the storage medium 1 mounted on the product 2 returned to the inspection process by the second recording medium reading unit 6 is performed.

  On the other hand, if it is determined in step S4 that the NG of the inspection result in step S3 is NG after the reinspection, the repair history database 13 is updated in step S16. That is, data whose reinspection result matches the NG model, serial number and defective item is retrieved from the repair history database 13, the reinspection result and reinspection date are rewritten, and the process returns to step S5.

  By repeating the processes in steps S1 to S16 until the result of reinspecting the defective product becomes OK, the defective product can be reliably repaired.

  In the present embodiment, an example of highlighting a repaired part of a product on an exploded view of a part is described. However, as a specific application example, for example, a repaired part of a board is highlighted on a printed circuit board diagram. Thus, it is possible to accurately grasp the repaired parts such as circuit parts.

  The repair support program of the present invention causes a computer to execute the repair support method implemented by the above-described repair support system, and the recording medium of the present invention is a computer-readable recording medium storing the repair support program. is there. As an example of the recording medium, a semiconductor storage element such as a mask ROM (Read Only Memory) and a flash ROM, a hard disk, a flexible disk, an MO (Magneto-Optic) disk, a CD-ROM (Compact Disc Read Only Memory), a DVD-ROM.
