The analysis device 20 is also connected to the control device 16, and information analyzed by the analysis device 20 is transmitted to the control device 16.

<Mounting work with a mounting machine>
In the mounting machine 26, the mounting operation can be performed by the mounting head 36 on the circuit board held by the transport device 32 with the above-described configuration. Specifically, the circuit board is transported to the work position according to a command from the control device 16, and is fixedly held by the board holding device at that position. Further, the tape feeder 68 sends out a taped component and supplies an electronic component at a supply position in accordance with a command from the control device 16. Then, the mounting head 36 is moved above the supply position of the electronic component according to a command from the control device 16, and the electronic component is sucked and held by the suction nozzle 62. Subsequently, the mounting head 36 moves above the circuit board according to a command from the control device 16. The mounting head 36 adjusts the vertical position of the electronic component held by the operation of the nozzle lifting device and mounts the electronic component at a predetermined position on the circuit board.

<Calculation of work error occurrence time zone>
In the mounting machine 26, as described above, the mounting operation of the electronic component to the circuit board is performed, and various operations by the operator are performed before and during the mounting operation. Specifically, an operator performs an input operation using the input device 14, a setup operation necessary for executing the mounting operation, an electronic component replenishment operation during the mounting operation, and the like.

  Examples of the input operation to the input device 14 include input of a program or the like corresponding to the circuit board, change of a parameter or the like accompanying change of the circuit board type, and the like. In addition, the setup work includes replacement of the tape feeder 68 according to the electronic parts required for the mounting work, storage of the suction nozzle 62 in the nozzle changer 70 according to the electronic parts, and the like. Examples of the electronic component replenishment operation during the mounting operation include a splicing operation for a taped component, a replacement operation for the tape feeder 68, and the like.

  Since the above-described input work, setup work, replenishment work, and the like are performed by an operator, work mistakes inevitably occur. It is desirable that such work mistakes be as small as possible. For this reason, the electronic component mounting system 10 estimates a time zone in which work mistakes are likely to occur by an operator (hereinafter sometimes referred to as “work error occurrence time zone”), and works in the work error occurrence time zone. Various measures are taken to suppress the occurrence of mistakes.

  Specifically, whenever the worker performs an operation on the electronic component mounting device 12 or the input device 14, information on the work content by the operator is transmitted from the electronic component mounting device 12 or the input device 14 to the control device 16. Sent to. When the control device 16 receives the information regarding the work content, the control device 16 transmits the time when the information is acquired to the database 18 together with the information regarding the work content as the time when the work is executed. Then, the database 18 stores the received information on the work content and the work execution time in association with each other.

  Further, the control device 16 determines whether or not the work that is the basis of the received information regarding the work content has been appropriately performed. Specifically, for example, when the information regarding the work content is information regarding the replenishment operation of the electronic component, whether or not the replenishment operation of the electronic component was appropriately performed, that is, whether the appropriate electronic component was replenished It is determined whether or not. When the information regarding the work content is information regarding the input work of the program using the input device 14, it is determined whether or not the input work of the program has been appropriately performed, that is, the mounting work has been appropriately performed according to the program. It is determined whether or not.

  When it is determined whether or not the work has been appropriately performed, the result of the determination, that is, the work result is transmitted to the database 18 together with information on the work content. Then, the database 18 stores the work result in association with the information regarding the work content acquired earlier and the work execution time. Thereby, the information regarding the work content, the execution time of the work, and the work result are associated with each other as a work history and stored in the database 18.

  Since the work history is stored for each work performed by the worker on the electronic component mounting device 12 or the input device 14, a relatively large amount of work history is stored in the database 18. Then, based on these many work histories, the operation error occurrence time zone is calculated by the analyzer 20.

  Specifically, the analysis device 20 acquires a plurality of work histories stored in the database 18 and classifies the work execution time and work results for each category of work contents. Next, the analysis device 20 extracts an unfavorable work result from a plurality of work results for each category, and also extracts an execution time of the work associated with the unfavorable work result. Then, the analysis device 20 calculates a work error occurrence time zone based on the work execution time associated with the work result that is not good.

  Specifically, for example, the number of work error occurrences per unit time is measured, and a time zone in which the number of work error occurrences per unit time is equal to or greater than a set number is set as a work error occurrence time zone. It is also possible to calculate a work error occurrence time zone using a standard deviation or the like. Note that the calculated operation error occurrence time zone can be calculated not only by time but also by day of the week and date. That is, for example, the time zone from 16:00 to 17:00 on Friday, the time zone from 9:00 to 10:00 on January 6, and the like can be calculated as the work error occurrence time zone.

<Control of electronic component mounting device using work error occurrence time zone>
When the work error occurrence time zone is calculated by the analysis device 20, the calculated work error occurrence time zone is transmitted to the control device 16. Then, the control device 16 controls the operation of the electronic component mounting device 12 or the input device 14 using the acquired work error occurrence time zone. In the electronic component mounting system 10, four control methods are employed as the control method of the electronic component mounting device 12 or the input device 14 using the work error occurrence time zone, and each control method will be described below. To do.

  As a first control method, a control method for displaying a work instruction to the worker on the panel device 72 or the monitor 78 while avoiding a work error occurrence time zone is employed. Specifically, for example, when the work error occurrence time zone is from 17:00 to 18:00, and the replacement work of the electronic component in the work error occurrence time zone is scheduled, before 17:00, An instruction to perform the replacement work is displayed on the panel device 72. Further, if there are no shortage of electronic parts even if the electronic parts are not replaced by 18:00, an instruction to execute the electronic parts replacement work is displayed on the panel device 72 after 18:00. Thereby, it becomes possible to prevent the operator's work in the work error occurrence time zone, and it is possible to suppress the occurrence of the work error.

  As a second control method, when a work instruction to the worker is displayed on the panel device 72 or the monitor 78 during a work error occurrence time zone, pay attention to the execution of the work together with the work instruction to the worker. A control method for displaying information to evoke is adopted. Specifically, for example, if the electronic component replacement operation is not performed during the work error occurrence time period, and the mounting operation is interrupted due to a shortage of electronic components, an instruction to perform the electronic component replacement operation is given. At the same time, in the electronic part replacement work in the current time zone, work mistakes frequently occur, so a comment that prompts the user to perform the replacement work with caution is displayed on the panel device 72. Thereby, it becomes possible to suppress the occurrence of work mistakes in the work error occurrence time zone by alerting the worker.

  As a third control method, a control method is employed in which an operator operates a predetermined instrument after the work is completed. Specifically, for example, when an electronic component replacement operation is performed during a work error occurrence time zone, the replacement is performed on the condition that the confirmation button 76 is operated after the operator replaces the tape feeder 68. The work is complete. That is, after replacing the tape feeder 68, the operator confirms the type, the mounting position, and the like of the replaced tape feeder 68 and operates the confirmation button 76. Then, in the electronic component mounting apparatus 12, it is determined that the replacement work has been completed by operating the confirmation button 76. Accordingly, it is possible to secure a time for the operator to confirm the work content before the work is completed, and it is possible to suppress the occurrence of the work mistake in the work error occurrence time zone. It should be noted that, in the replacement operation of the electronic component in a time zone other than the operation error occurrence time zone, it is determined that the replacement operation is completed even if the confirmation button 76 is not operated.

  As a fourth control method, a control method for prohibiting the execution of work by the worker in the work error occurrence time zone is employed. Specifically, for example, when a worker inputs a new parameter in order to change a parameter or the like using the input device 14 during a work error occurrence time period, the input parameter is not changed, Existing parameters are maintained. Then, a comment indicating that the parameter cannot be changed is displayed on the monitor 78 in the work error occurrence time zone. Thereby, it becomes possible to prohibit the operator's work in the work error occurrence time zone, and it is possible to suppress the occurrence of work mistakes.

  As shown in FIG. 1, the control device 16 includes an execution instruction output unit 80, an alert information output unit 82, an operation control unit 84 for each time zone, and a work execution prohibition unit 86. The execution instruction output unit 80 is a functional unit for displaying a work instruction to the worker on the panel device 72 or the monitor 78 while avoiding a work error occurrence time zone. The alert information output unit 82 alerts the execution of the work together with the work instruction to the worker when the work instruction to the worker is displayed on the panel device 72 or the monitor 78 during the work error occurrence time zone. This is a functional unit for displaying information to that effect. The time zone operation control unit 84 is a functional unit for causing the operator to operate the confirmation button 76 after the work is completed. The work execution prohibition unit 86 is a functional unit for prohibiting the work by the worker in the work error occurrence time zone.

  Moreover, the processing flow of each apparatus for suppressing generation | occurrence | production of the work mistake mentioned above is shown in FIG. 3 and FIG. First, as shown in FIG. 3, the worker performs work on the control device 16 or the input device 14 (S100). Next, the work performed by the worker, the execution time of the work, and the work result of the work are transmitted from the control device 16 to the database 18. In the database 18, the work performed by the worker, the execution time of the work, The work result of the work is associated and stored (S102). Subsequently, it is determined whether or not the mounting work has been completed (S104). If the mounting work has not been completed (S104: NO), the process returns to S100. On the other hand, when the mounting operation is completed (S104: YES), this flow ends.

  As shown in FIG. 4, the analysis device 20 acquires the work performed by the worker, the execution time of the work, and the work result of the work from the database 18 as a work history, and based on the work history. The operation error occurrence time zone is calculated (S110). Next, the analyzer 20 transmits a work error occurrence time zone to the control device 16 (S112). Subsequently, the control device 16 controls the operation of the electronic component mounting device 12 or the input device 14 according to the above four control methods using the work error occurrence time zone (S114). Then, it is determined whether or not the mounting work is completed (S116). If the mounting work is not completed (S116: NO), the process returns to S110. On the other hand, when the mounting operation is completed (S116: YES), this flow ends.

Then, the analysis device 20 calculates a work content category and a work error occurrence time zone for each worker. As a result, it is possible to take countermeasures against occurrence of work mistakes according to the operator, and to effectively prevent the occurrence of work mistakes.
