  The best mode for carrying out the present invention will be described below in detail with reference to the drawings. Here, a case will be described in which the present invention is applied to an assembly system that performs an assembly operation of a digital camera by a cell production method.

[First Embodiment]
First, a configuration of an assembly work system 10 to which the present invention is applied will be described with reference to FIG.

  As shown in the figure, the assembly work system 10 according to the present embodiment is a digital camera in which an operator 80 combines various components such as a lens unit 60A, an imaging substrate unit 60B, a housing unit 60C, and a main substrate 60D. 60 is to be assembled by a cell production system, and includes a personal computer (hereinafter referred to as “PC”) 20 having a central role of the system 10.

  In the assembling work system 10 according to the present embodiment, one PC 20 is provided at a position that can be operated by an operator with respect to one cell stand, and a plurality of workers can mutually connect one cell stand. It is supposed to be used at different times.

  Next, with reference to FIG. 2, the principal part structure of the electric system of PC20 which concerns on this Embodiment is demonstrated.

  As shown in the figure, the PC 20 according to the present embodiment includes a CPU (Central Processing Unit) 20A that controls the operation of the PC 20 as a whole, a RAM 20B that is used as a work area when the CPU 20A executes various processing programs, and the like. ROM 20C in which a control program, various parameters, and the like are stored in advance, a hard disk 20D used to store various information, a keyboard 20E used to input various information, and a display used to display various information 20F and a buzzer 20G are provided, and these units are electrically connected to each other by a system bus BUS.

  Therefore, the CPU 20A can access the RAM 20B, ROM 20C, and hard disk 20D, obtain various input information via the keyboard 20E, display various information on the display 20F, and sound the buzzer 20G.

  On the other hand, FIG. 3 schematically shows the main storage contents of the hard disk 20D provided in the PC 20. As shown in the figure, the hard disk 20D is provided with a database area DB for storing various databases, and a program area PG in which processing programs for performing various processes by the PC 20 are stored in advance.

  Here, in the database area DB, a standard information database in which information for unifying the information related to defective products input by each worker in the assembly work system 10 in a unique expression is stored in advance in the same expression. DB 1, a worker information database DB 2 in which information for identifying which worker is performing the assembly work is stored in advance, and information regarding defective products that are discovered and input by the worker. Of defect information database DB3.

  As shown in FIG. 4, the standard information database DB <b> 1 according to the present embodiment is configured to store information on categories, standard expression information, and worker-specific expression information.

  The category is information indicating the type of information related to a defective product that is supported in the assembly work system 10 according to the present embodiment. As shown in the figure, in the standard information database DB1 according to the present embodiment, as the category, “part name” indicating the name of the defective product, “defective name” indicating the name of the defect, and the degree of defect are shown. Each information of “degree”, “location” indicating the position of the defective portion, and “quantity” indicating the number of defects is applied.

  On the other hand, the standard expression information is information that is an expression that should be unified with respect to information regarding defective products that are supported in the assembly work system 10 according to the present embodiment. As shown in the figure, in the standard information database DB1 according to the present embodiment, as the standard expression information, “lens part”, “imaging board part”, “casing part” and the like belonging to the above “part name” “Scratch”, “Burn”, “Coslet”, etc. belonging to the “Bad name”, “Level 1”, “Level 2”, etc. belonging to the “Degree”, and “A-1” belonging to the “Location” ”,“ B-1 ”,“ C-1 ”, etc., and“ less than 10 ”,“ less than 100 ”,“ less than 1000 ”, etc. belonging to the“ quantity ”are stored in advance.

  Further, the worker-specific expression information is information related to defective products by expressions unique to each worker corresponding to the corresponding standard expression information. As shown in the figure, in the standard information database DB1 according to the present embodiment, for example, “lens”, “medium scratch”, “large scratch”, “upper surface”, and the like as the worker-specific expression information of the worker A However, “lens part”, “scratch 1”, “small level”, “upper”, and the like are stored in advance as expression information for each worker B.

  That is, in the standard information database DB1 shown in the figure, for example, the standard expression corresponding to the original expression “scratched” by the worker A is “scratch” in the information about the defective product whose category belongs to the defect name. The standard expression corresponding to the unique expression “scratch 2” by the worker B is “Kake”.

  In the assembling work system 10 according to the present embodiment, the interview information of the worker-specific expression information is preliminarily investigated from each worker, and the standard information database DB1 is constructed using the information obtained thereby.

  On the other hand, although not shown in the figure, the worker information database DB2 includes information for identifying the worker performing the assembly work for each worker who is permitted to perform the assembly work by the assembly work system 10. Information given in advance as individual information (in this embodiment, a password) is stored in a state associated with information (here, ID (Identification) information) that can identify the corresponding worker. Yes.

  Although not shown, in the defect information database DB3, information related to the defective product discovered and input by the operator during the assembly operation of the digital camera 60 (in the present embodiment, the above "part name", " At least one piece of information such as “defective name”, “degree”, “location”, and “quantity”) is stored for each worker.

  Next, the operation of the assembly work system 10 according to the present embodiment will be described.

  First, with reference to FIG. 5, the operation of the assembly work system 10 when the digital camera 60 is being assembled will be described. 5 is executed by the CPU 20A of the PC 20 when an execution instruction is input via the keyboard 20E by the worker 80 (hereinafter referred to as “processing subject worker”) when the assembly work is performed. It is a flowchart which shows the flow of a process of an assembly work management processing program, and the program is stored in advance in the program area PG of the hard disk 20D. Here, a case will be described in which the password previously assigned to the processing target worker is input via the keyboard 20E prior to execution of the assembly work management processing program. Here, the case where the standard information database DB1 is schematically shown in FIG. 4 will be described.

  In step 100 of the figure, by determining whether or not the password input by the processing target worker exists in the worker information database DB2, the processing target worker can perform the assembly work by the assembly work system 10. It is determined whether the worker is permitted or not. If the determination is negative, the process proceeds to step 102. If the determination in step 100 is affirmative, the worker corresponding to the ID information associated with the password entered by the processing target worker in the worker information database DB2 is the processing target worker. Can be specified.

  In step 102, after notifying the processing target worker that the assembly work should not be performed, the present assembly work management processing program is terminated. In the assembly work management processing program according to the present embodiment, the notification is performed by sounding for a predetermined period (here, 10 seconds) by the buzzer 20G. However, the present invention is not limited to this, for example, by the display 20F. It goes without saying that other forms such as a form performed by displaying a message instructing execution stop of the assembly work can be adopted.

  On the other hand, if the determination in step 100 is affirmative, the process proceeds to step 104. Here, if the processing target worker starts the assembly work of the digital camera 60 and finds a defective product during the execution of the assembly work, information about the defective product is expressed by his / her expression at that point in time on the keyboard. Input via 20E. For example, when a moderate scratch exists on the upper portion of the lens unit 60A, the worker A inputs information such as “lens”, “upper surface”, “level 2”, and “scratched”, and the worker B , "Lens part", "upper", "medium level", and "scratch 1" information (worker-specific expression information) is input.

  Therefore, in step 104, the processing target worker waits for input of the worker-specific expression information, and in the next step 106, the work corresponding to the worker specified by the processing in step 100 is input. By reading the standard expression information corresponding to the expression information for each person from the standard information database DB1, the input expression information for each worker is converted into the standard expression information. As a result, regardless of which worker is the processing target worker, for example, the inputted worker-specific expression information corresponds to the above-mentioned “when there is a medium scratch on the upper portion of the lens unit 60A”. If there is, it can be converted into unified standard expression information of “lens part”, “A-1”, “level 2”, and “scratch”.

  In the next step 108, the standard expression information obtained by the process in the above step 106 is registered in the defect information database DB3 in a predetermined format, and in the next step 110, it is determined whether or not the timing for finishing the assembly work has come. If the determination is negative and the determination is negative, the process returns to step 104. When the determination is affirmative, the present assembly work management processing program is terminated. Note that, in the assembly work management processing program according to the present embodiment, the timing at which the assembly work is finished is the timing at which the predetermined assembly work time period of the identified worker to be processed is finished. Needless to say, for example, other timing such as the timing at which information indicating the end of work is input by the processing target worker via the keyboard 20E can be used.

  By executing this assembly work management processing program, as shown schematically in FIG. 6 as an example, when a defective product such as a scratch is found in the assembly process of the digital camera 60, the assembly worker himself / herself uses a unique expression. Information on the defective product is input via the keyboard 20E, the information is converted into standard expression information using the standard information database DB1, and is registered in the defect information database DB3 in a state where the information can be centrally managed.

  Next, with reference to FIG. 7, an operation of the assembly work system 10 after the assembly work of the digital camera 60 is completed will be described. Note that FIG. 7 shows the case where the assembly work is completed and the information regarding the defective product is registered in a free format, and when the execution instruction for the registration is input via the keyboard 20E by the processing target worker. 6 is a flowchart showing the flow of processing of an assembly work end processing program executed by the CPU 20A, and the program is also stored in advance in the program area PG of the hard disk 20D. Also here, a case will be described in which the password previously assigned to the processing target worker is input via the keyboard 20E prior to the execution of the assembly work end processing program. Also here, a case where the standard information database DB1 is schematically shown in FIG. 4 will be described.

  In step 200 of the figure, by determining whether or not the password input by the processing target worker exists in the worker information database DB2, the processing target worker can perform the assembly work by the assembly work system 10. It is determined whether the worker is permitted or not. If the determination is negative, the process proceeds to step 202. If the determination in step 200 is affirmative, the worker corresponding to the ID information associated with the password input by the worker to be processed in the worker information database DB2 is the worker to be processed. Can be specified.

  In step 202, the processing target worker is notified that the processing program at the end of assembly work should not be executed, and then the processing program at the end of assembly work is ended. In the processing program at the end of assembly work according to the present embodiment, the notification is performed by ringing for a predetermined period (here, 20 seconds) by the buzzer 20G. However, the present invention is not limited to this. For example, the display 20F It goes without saying that other forms such as a form performed by displaying a message indicating that the execution of the program is stopped can be used.

  On the other hand, if the determination in step 200 is affirmative, the process proceeds to step 204. Here, the worker to be processed inputs information on the defective product in the free format via the keyboard 20E. For example, if more than 100 and less than 1000 lens parts 60A with moderate scratches are found at the top, worker A says, “There were a large number of lenses with level 2 scratches on the top surface.” The information is input, and the worker B inputs the information that “there are many lens parts having scratches 1 in the level above”.

  Therefore, in step 204, the processing target worker waits for input of the information (hereinafter referred to as “free format sentence”), and in the next step 206, a word is extracted from the free format sentence by a conventionally known technique. Thereafter, the standard expression information corresponding to the worker identified by the process of step 200 and corresponding to the extracted word is read from the standard information database DB1, thereby converting the word into standard expression information. As a result, regardless of which worker is the processing target worker, for example, the input free format sentence is “the lens part 60A having a moderate scratch on the upper part is found to be 100 or more and less than 1000. If it corresponds to “Case”, the standard in which the words in the free format sentence are “A-1”, “Level 2”, “Scratch”, “Lens”, “Less than 1000” It can be converted into expression information.

  In the next step 208, the free format sentence is converted into a standard expression sentence by replacing the corresponding word of the free format sentence with the word that has been made into the standard expression information by the process of step 206, and in the next step 210, Whether the standard expression text obtained by the process of step 208 is registered in the defect information database DB3 in a predetermined format, and whether or not the timing to end the processing program at the end of the assembly work has come in the next step 212. When the determination is negative, the process returns to step 204, and when the determination is affirmative, the processing program at the end of the assembling operation is terminated. Note that, in the assembly work end time processing program according to the present embodiment, the timing at which the assembly work end time processing program ends is set to a predetermined time (for example, the elapsed time from the start of execution of the assembly work end time processing program). However, the present invention is not limited to this, for example, the timing at which information for instructing the end of execution of the processing program at the end of the assembly work is input via the keyboard 20E by the worker to be processed, etc. It goes without saying that the timing can also be used.

  Next, the operation of the assembly work system 10 when useful information is extracted from the free format text registered in the defect information database DB3 by the above assembly work end time processing program will be described with reference to FIG. FIG. 8 is a flowchart showing a flow of processing of a useful information extraction processing program executed by the CPU 20A of the PC 20 at a predetermined timing (here, when one week of assembly work is completed). Is also stored in advance in the program area PG of the hard disk 20D.

  In step 300 in the figure, the free format sentence registered by the processing program at the end of assembly work is read from the defect information database DB3, and in the next step 302, a conventionally known text mining technique is applied to the read free format sentence. By doing so, useful information is extracted from the free format sentence. Through the above processing, for example, information of “A-1”, “level 2”, “scratch”, “lens part”, and “less than 1000” is extracted.

  Therefore, in the next step 304, the useful information extracted by the above processing is registered in the defect information database DB3 in a predetermined format, and then the useful information extraction processing program is terminated.

  By executing the above assembly work end processing program and useful information extraction processing program, as shown schematically in FIG. 9 as an example, after the assembly process of the digital camera 60 is completed, the assembly worker left an impression. Information related to the non-defective product is inputted as a free format sentence by the assembly operator's own expression through the keyboard 20E, and the information is converted into standard expression information using the standard information database DB1, and further useful by the text mining technique. Only the information is registered in the defect information database DB3 in a state where the information can be centrally managed.

  As described above in detail, in the present embodiment, the worker who is assembling the predetermined assembly (here, the digital camera 60) and the assembling operation discovered when the assembling operation is being performed. For each worker who inputs defective product information regarding defective products of parts used in the above, unified with the worker-specific expression information by the original expression of the corresponding worker as a plurality of predetermined information indicating the defective product information Is stored in advance by a storage means (here, the hard disk 20D) in association with the standard expression information by the expressed expression, and the defective product information using the worker-specific expression information is input by any of the workers. The worker inputting the defective product information is identified, corresponds to the identified worker, and corresponds to the worker-specific expression information included in the input defective product information. By reading the standard expression information from the storage means, the worker-specific expression information included in the input defective product information is converted into the standard expression information. Can be easily input as unified expression information.

  Further, in the present embodiment, the plurality of information includes defective product specifying information (here, information belonging to “part name”) that can specify the defective product, and a defect indicating a name of the defective product. Name information (here, information belonging to “defect name”), defect degree information indicating the degree of defect (here, information belonging to “degree”), defect position information indicating the position of the defect (here, “ Information), and information on the number of defective products (in this case, information belonging to “quantity”) indicating the number of defective products. Therefore, these pieces of information can be easily input as unified expression information. it can.

  In this embodiment, since the storage means further stores the standard expression information obtained by the conversion, the standard expression information can be used at an arbitrary timing, improving convenience. Can be made.

  In the present embodiment, the defective product information is input both during the assembly operation, when the defective product is found, and when the assembly operation is completed in a predetermined period. Therefore, it is possible to deal with an application in which defective product information needs to be input at each time point.

  In particular, in the present embodiment, when the assembly work is completed in units of a predetermined period, a sentence using the expression information by worker (here, a free format sentence) is input as the defective product information, Since effective word information is extracted by the text mining technique from the sentence after the worker-specific expression information is converted into the standard expression information and stored by the storage means, the effective word information is converted into the standard expression information. Various processes such as statistical processing using the word information can be performed easily and with high accuracy.

[Second Embodiment]
In the second embodiment, a description will be given of an example in which information regarding defective products (worker-specific expression information) is input by voice.

The only difference is that the input source of information regarding defective products is the microphone 20I in each process.

  Therefore, in the assembling work system 10 according to the second embodiment, as schematically shown in FIG. 11 as an example, when a defective product such as a scratch is found in the assembling process of the digital camera 60, the assembling work is performed. The information regarding the defective product is input by voice in the original expression of the person himself, the information is converted into standard expression information using the standard information database DB1, and is registered in the defect information database DB3 in a state where the information can be centrally managed. Will be.

  In this embodiment, the same effects as in the first embodiment can be obtained, and defective product information is input as voice information, so that an operation on an input device such as a keyboard is not required. It is possible to suppress a decrease in the efficiency of assembly work due to the above.
