On the display / operation unit 14, three process selection buttons including a defect information registration button B 1, a defect information edit button B 2 and a file output button B 3 are displayed in a selectable manner. Also, an end button B4 and a return button B5 are displayed so as to be selectable.

  When the defect information registration button B1 is selected, the function of the defect information registration unit 32 is executed. That is, the defect information registration unit 32 registers defect information in the manufacturing management DB 50 when a defect occurs for a certain product for the first time. Items to be registered are “Kanban or name information”, “defective product tag type”, “product product number”, “registration date”, “occurrence time”, “serial number”, “jig No”, “change point presence / absence”, “terminal”, “ "Cavity" "Wire Color" "Size" "Bug Details" "Wire Type" "Core Wire Exposure" "Wire Scratch Terminal" "Distance from Tip" "Scratch Type Name" "Generation Process" "Discovery Process" "Return Destination Process" There are “retouching date”, “retoucher”, “retoucher”, “registrant”, and “remarks”. Basically, these items can be selected from predetermined options. For example, when the operator presses each item displayed on the display / operation unit 14 with a stylus (touch pen) or the like, a plurality of contents that can be registered are displayed, and a desired one is selected from them.

  When the defect information editing button B2 is selected, the function of the defect information editing unit 34 is executed. That is, the defect information editing unit 34 calls the defect information from the manufacturing management DB 50 when registering the work contents after reworking in the repair process of a product for which defect information has already been registered, or when a defect occurs again. To edit. If there is a retouched image, it is added to the defective part image storage unit 54.

  When the file output button B3 is selected, the function of the defective bulletin creation unit 36 is executed. In other words, the failure bulletin creation unit 36 outputs a failure bulletin of a predetermined format from the printer 90. Here, the failure bulletin creation unit 36 accesses the defect information storage unit 52 and the defect location image storage unit 54 of the manufacturing management DB 50 to call out defect information of a desired production number, convert it into a predetermined format, and display / display it. Displayed once on the operation unit 14, and if there is no problem, prints out according to the instructions of the operator.

  FIG. 4 is a flowchart showing an outline of the defect information processing step in the manufacturing management system 1.

  The operator operates the tablet terminal 10 to activate the manufacturing management system application. If the defect management data file does not exist in the manufacturing management DB 50 (N in S10), that is, if the desired defect content storage ledger does not exist in the defect information storage unit 52 or cannot be accessed, the process ends.

  When the defect information data file exists in the manufacturing management DB 50 (Y in S10), the tablet terminal 10 takes in the master data from the manufacturing management DB 50 (S12). Subsequently, the tablet terminal 10 reads the worker code, that is, the worker ID from the worker (S14). As described above, the language used is associated with the worker ID, and in each process in the manufacturing management system application, the language used by the read worker ID is determined and set in the management setting unit 38. More specifically, the language displayed on the display / operation unit 14 and the language used for writing are determined. For example, if the language used associated with the worker ID is “Thai”, the language displayed on the display / operation unit 14 is both “Japanese” and “Thai”.

  Subsequently, the worker selects processing contents on the screen shown in FIG. 3 (S16). When the defect information registration button B1 is pressed (A1 in S16), defect information registration processing is executed (S20). When the defect information editing button B2 is pressed (A2 in S16), defect information editing processing is executed (S30). When the file output button B3 is pressed (A3 in S16), a file output process is executed (S40). With file output processing, items extracted under desired conditions are printed out as a list or output as electronic data with respect to the defect information recorded in the defect information storage unit 52 or the defect location image storage unit 54. It is processing. The item extracted under the desired condition is, for example, defect information within a selected date, or defect information for one week of a desired product number. In addition, a failure bulletin may be output.

FIG. 6 is a diagram for explaining the outline of the registered content label output process. FIG. 7 is a flowchart showing more specific contents of the defect information registration process (S20 in FIG. 4).

  As shown in FIG. 5, the worker confirms the state of the product in which the defect has occurred, registers the defect content, photographs the defective portion with the camera 16 of the tablet terminal 10, and manufactures the manufacturing management DB 50 (defect information storage). Unit 52 and defective part image storage unit 54).

  Further, as shown in FIG. 6, the operator confirms the state of the product in which the defect has occurred, registers the defect content, and prints the registered defect content using the label printer 92 with a label. The printed label is affixed to the defective product tag.

  The label describes a two-dimensional code in which registered contents are encrypted. Here, the contents described in the two-dimensional code include information accessible to the manufacturing management DB 50 regarding the product at least in the subsequent processes, such as “Kanban or name information”, “product part number”, “management number”, etc. It is. By reading this two-dimensional code in subsequent work, for example, defect information editing work in the rework process, the tablet terminal 10 and other management devices can acquire the registered contents.

  With reference to FIG. 7, more specific contents of the defect information registration process (S20 in FIG. 4) will be described. When the defect information registration process is started, the defect information registration unit 32 of the tablet terminal 10 acquires a management number by the operation of the operator (S21). Next, the defect information registration unit 32 accepts registration of defect information from the worker (S22), and takes a picture of a defective part of the product by the camera 16 (S23).

  When the label issuing software is provided in the tablet terminal 10 (Y in S24), that is, when the worker has the authority to issue the label and the label printer 92, the defect information registration unit 32 activates the label issuing software (S25). Based on the registered contents, a label in a predetermined format is printed out (S26).

  When there is no label issuing software (N in S24) or when the label output is finished (S26), the defect information registration unit 32 creates and outputs defect breaking data as required (S27), and the defect information registration process is completed. (S28).

  FIG. 8 is a diagram summarizing a specific flow of the print output process of the failure bulletin. The operator selects data to be output as a failure report from information recorded in the manufacturing management DB 50 (the failure information storage unit 52 and the defective part image storage unit 54), and outputs the data from the printer 90.

  FIG. 9 and FIG. 10 are diagrams showing examples of failure bulletins. In the failure bulletin shown in FIG. 9, the title of the “process failure bulletin”, the management number, the discovery date, the content of the defect, the product part number, etc. are described in the upper part. Below them is a picture of the defective part, especially on the left side. Also, on the right side, details of the defect and instructions are written. These contents are written in Thai along with Japanese based on the worker ID. The content of the defect is “electrical wire scratch”, and the photograph of the normal state is placed on the top and bottom of the photograph so that they can be compared with each other. The upper photograph is a photograph of a defective part of the product, and the lower photograph is a photograph of a normal state after reworking. Also, these photo areas have a predetermined size and are automatically adjusted to a predetermined size.

  In the failure bulletin shown in FIG. 10, “process failure bulletin” and a management number are described in the upper part. In the next level, the presence / absence of the core wire exposure, the flaw position, and the flaw type are described. The scratch type is specified by a number. Below them, nine types of scratch type photographs are shown in association with numbers. Each photograph also includes a schematic diagram of the scratch type. The scratch type can be easily identified regardless of the skill level of the operator. Further, these contents are shown in Thai together with Japanese as in FIG. Even if the language used is different among workers, it is easy to send and share defect information.

  FIG. 11 is a diagram for explaining the outline of the defect information editing process. FIG. 12 is a flowchart showing more specific contents of the defect information editing process (S30 in FIG. 4).

  As shown in FIG. 11, when the operator determines that there is content to be added to the defect information, the defect information editing unit 34 uses the camera 16 to output a two-dimensional code (identification code) of the label output by the defect information registration operation. ) And the target data is fetched from the manufacturing management DB 50. The defective part is photographed as necessary, and the edited data is stored in the manufacturing management DB 50 (the defect information storage unit 52 and the defective part image storage unit 54), and the label is printed from the label printer 92 in the same manner as in the defect information registration process. Printed or output as a failure report.

  When the defect information editing process is started, the defect information editing unit 34 of the tablet terminal 10 obtains a management number by the operator's operation (S31). Next, the defect information editing unit 34 accepts editing of defect information from the operator (S32). It is acquired from the operator, that is, from the display / operation unit 14 whether or not the retouched portion is shot (S33).

  If there is a photograph of the reworked part (Y in S33), the defect information editing unit 34 photographs the defective part of the product with the camera 16 by the operator's operation (S34).

  When there is no shooting of the retouched part (N in S34) or after the shooting is finished (S34), the defect information editing unit 34 edits the defect breaking data under an instruction from the operator's display / operation unit 14 (S35). Further, the defect information editing unit 34 outputs a new label from the label printer 92 (S36).

  If the contents to be edited remain (N in S37), the defect information editing unit 34 returns to the management number reading process (S31). If the editing is completed (Y in S37), the defect information editing unit 34 outputs the defect breaking data (S38), and ends the defect information editing process (S39).

  As described above, according to the present embodiment, when registering defect information or editing defect information, the operator does not need to fill in by hand and selects from predetermined items, so there is no problem with the entry format. Further, since the language used by the workers is reflected in the input / display processing, it becomes easy to share information among the workers even when the languages used are different. In addition, since the size of the image of the defective portion is automatically adjusted in the defective bulletin, the efficiency of the work for creating and editing the defective bulletin is improved.

  The present invention has been described based on the embodiments. This embodiment is an exemplification, and it is understood by those skilled in the art that various modifications can be made to each of those components and combinations thereof, and such modifications are also within the scope of the present invention.
