<Working with substrate on work machine>
In the work machine 10, with the above-described configuration, it is possible to perform mounting work as a work for a substrate by the work head 16 on the circuit board 12 held by the transfer device 14. More specifically, first, the circuit board 12 is transported to the mounting work position by the transport device 14, and the circuit board 12 is fixedly held at the position. Next, the working head 16 is moved onto the circuit board 12 by the moving device 18, and the circuit board 12 is imaged by the mark camera 80. By the imaging, the type of the circuit board 12 and the holding position error of the circuit board 12 by the transfer device 14 are acquired. The circuit component corresponding to the acquired type of the circuit board 12 is supplied by the tape feeder 70 of the tape-type supply device 20 or the component tray 72 of the tray-type supply device 22, and the circuit component is supplied to the circuit component supply position. The head 16 is moved by the moving device 18. As a result, the circuit component is sucked and held by the suction nozzle 34 of the work head 16. Subsequently, the work head 16 holding the circuit components is moved onto the parts camera 82 by the moving device 18, and the circuit components held by the work head 16 are imaged by the parts camera 82. A holding position error of the circuit component is acquired by the imaging. Then, the working head 16 is moved to the mounting position on the circuit board 12 by the moving device 18, and the mounting nozzle 34 is rotated based on the holding position error between the circuit board and the circuit parts by the working head 50. Is installed.

<Replacement with circuit board type change>
In the work machine 10, the mounting operation of the circuit components is performed on the circuit board as described above, but the mounting work can be performed on various types of circuit boards. That is, it is possible to exchange the types of circuit boards and perform mounting work on different types of circuit boards. Specifically, for example, after execution of the first mounting operation for mounting the first to fourth circuit components on the first circuit board is completed, the second circuit board having a different size from the first circuit board is formed. On the other hand, it is possible to execute the second mounting operation for mounting the fifth to eighth circuit components. In order to execute the second mounting operation after the first mounting operation, the distance between the pair of conveyor belts 24, that is, the width of the conveyor is changed in order to transport the second circuit boards having different sizes. Furthermore, it is necessary to change from a supply device capable of supplying the first to fourth circuit components to a supply device capable of supplying the fifth to eighth circuit components. Thus, along with the change in the type of circuit board, it is necessary to change the conveyor width, change the supply device, and the like.

  The setup change accompanying the type change of the circuit board includes setup change that can be performed by operating the conveyor width changing mechanism 30 of the transport device 14 like the conveyor width change, that is, automatic setup change. On the other hand, there is a changeover in which the operator manually removes the supply device from the base and attaches a supply device different from the removed supply device to the base, that is, a manual changeover, such as replacement of the supply device. Conventionally, these two types of setup changes have been performed in order, and are operations that require a relatively long time.

Specifically, in the conventional procedure, as shown in FIG. 5A, after a change in the type of the circuit board is input to the work machine, one supply of a pair of supply devices is performed to perform manual setup change. It was possible to replace the device (hereinafter referred to as “first supply device”). Specifically, by operating the supply device fixing mechanism corresponding to the first supply device, the first supply device is released from being fixed by the supply device fixing mechanism, and the operator replaces the first supply device. Then, the first supply device is fixed to the base by the supply device fixing mechanism. When the replacement operation of the first supply device is completed, the operator moves to the other supply device (hereinafter referred to as “second supply device”) of the pair of supply devices, and replaces the second supply device. . Specifically, by operating the supply device fixing mechanism corresponding to the second supply device, the fixation of the second supply device by the supply device fixing mechanism is released, and the operator replaces the second supply device. Then, the second supply device is fixed to the base by the supply device fixing mechanism. Then, the width of the conveyor is changed by operating the conveyor width changing mechanism to perform automatic setup change. When the setup change is performed in this way, the time required for the setup change is t ₁ as shown in FIG.

On the other hand, in this work machine 10, it is possible to reduce the time required for the setup change by performing the automatic setup change and the manual setup change in parallel. Specifically, as shown in FIG. 5B, when a circuit board type change is input to the work machine 10, the conveyor width is changed according to the circuit board type. When the change of the circuit board type is input, the fixing of the first supply device by the supply device fixing mechanism can be released. Therefore, the operator can replace the first supply device in a situation where the automatic setup change is performed by the conveyor width changing mechanism. As a result, the conveyor width change and the replacement of the first supply device can be performed in parallel, and the time required for the setup change can be set to t ₂ that is approximately 2/3 of the conventional setup change time t _1. It becomes.

  In the work machine 10, the changeover screen 100 as shown in FIG. 6 is displayed on the display devices 86 and 88 so that the supply device can be unfixed by the supply device fixing mechanism when the change of the circuit board type is input. Is displayed. The changeover screen 100 is divided into a changeover display area 102, a circuit board type selection area 104, an operation button area 106 for operating the supply device fixing mechanism, and an automatic changeover selection area 108. . The setup change display area 102 is an area for displaying the status of the setup change during work. When the setup change display area 102 is displayed as shown in FIG. 6, the supply device fixing mechanism corresponding to the first supply device performs the release operation. This indicates that the conveyor width changing mechanism 30 is executing the conveyor width changing. Further, four touch button type selection buttons 105 are displayed in the circuit board type selection area 104, and one of the first to fourth circuit boards is selected as the circuit board after the change. Is possible.

  In the operation button area 106, two touch button type operation buttons 107 are displayed, and one of the two buttons 107 is for operating a supply device fixing mechanism corresponding to the first supply device. The other is for operating a supply device fixing mechanism corresponding to the second supply device. However, the operation button 107 of the setup change screen 100 displayed on the first display device 86 can be operated only by the supply device fixing mechanism corresponding to the first supply device, and is displayed on the second display device 88. Only the supply device fixing mechanism corresponding to the second supply device can be operated on the operation button 107 on the setup change screen 100. Further, while one supply device fixing mechanism is operating, the operation of the operation button 107 for operating the other supply device fixing mechanism is invalid. That is, it is impossible to operate each supply device fixing mechanism from the two display devices 86 and 88 simultaneously.

  The display of the operation button 107 changes according to the operating state of the supply device fixing mechanism. Specifically, when the supply device fixing mechanism is fixing the supply device, the operation button 107 displays “release supply device”, and when the supply device fixing mechanism is releasing the supply device, the operation is performed. The button 107 displays “fixed supply device”. That is, the operation button 107 functions as a release button for releasing the fixation when the supply device fixing mechanism is fixing the supply device, and when the supply device fixing mechanism is releasing the fixation of the supply device, It functions as a fixed button for fixing the supply device. Incidentally, in the state in which the setup change screen 100 shown in FIG. 6 is displayed, since the two operation buttons 107 display “release supply device”, the first supply device and the second supply device are It is fixed by each supply device fixing mechanism.

  In the automatic setup change selection area 108, two selection radio buttons 109 are displayed, and it is possible to select whether the automatic conveyor width change is to be valid or invalid. . That is, it is possible to select whether or not to execute automatic conveyor width change after any button is selected in the circuit board type selection area 104. As shown in FIG. 4, a display unit 110 is provided in the controller 92 as a functional unit for displaying the setup change screen 100 on the display devices 86 and 88.

  A procedure for performing a setup change by operating the selection button 105 and the operation button 107 on the setup change screen 100 will be described with reference to a block diagram shown in FIG. Incidentally, it is assumed that the “valid” button is selected as the selection radio button 109. First, once the mounting operation to a certain circuit board is completed, in step 1 (hereinafter simply referred to as “S1”. The same applies to other steps), the production of the circuit board is completed, and in S2, The setup change screen 100 is displayed on the display devices 86 and 88. On the setup change screen 100, as shown in FIG. 6, a selection button 105 for selecting the type of the circuit board and an operation button 107 capable of releasing the fixing of the supply device are displayed at the same time. In S4, any button is operated by the operator.

  When the selection button 105 is operated, the width of the conveyor is automatically changed in S5. The automatic conveyor width change is performed by the operation of the conveyor width change mechanism 30. Before the conveyor width change mechanism 30 is operated, the presence or absence of a circuit board on the transfer device 14 is confirmed. Specifically, the pair of conveyor belts 24 is rotated for a certain time, and the presence or absence of the circuit board is confirmed by three detection sensors 98 provided between the pair of conveyor belts 24. Then, when it is confirmed that there is no circuit board on the transfer device 14, the conveyor width changing mechanism 30 is operated, and the conveyor width is automatically changed. Incidentally, as shown in FIG. 4, an automatic setup change execution unit 112 is provided in the controller 92 as a functional unit for performing the setup change automatically.

  Further, when the operation button (release button) 107 of the supply device fixing mechanism corresponding to the first supply device is operated, the fixation of the first supply device is released, and the operator replaces the first supply device in S6. Is possible. When the first supply device is replaced, in S7, the operation button (fixed button) 107 of the supply device fixing mechanism corresponding to the first supply device is operated, and the first supply device is fixed to the base. Subsequently, in S8, the operator moves from the arrangement side of the first supply device of the work machine 10 to the arrangement side of the second supply device. In S9, the operator supplies the supply device fixing mechanism corresponding to the second supply device. The operation button (release button) 107 is operated. As a result, the fixation of the second supply device is released, and the operator can replace the second supply device in S10. When the second supply device is replaced, in S11, the operation button (fixed button) 107 of the supply device fixing mechanism corresponding to the second supply device is operated, and the second supply device is fixed to the base. Incidentally, as shown in FIG. 4, a manual setup change state realization unit 114 is provided in the controller 92 as a functional unit for enabling execution of manual setup change by operating the operation buttons.

  When the automatic width change of the conveyor and the manual replacement of the pair of supply devices are completed, and the production start switch (not shown) is operated by the operator in S12, the confirmation operation of the conveyor width is performed in S13. Done. The confirmation operation of the conveyor width is an operation for confirming whether or not the actual conveyor width is the target conveyor width by the moving device 18, the mark camera 80, or the like. More specifically, the distance between the pair of conveyor belts 24 is obtained by moving the mark camera 80 onto the pair of conveyor belts 24 by the moving device 18 and imaging the pair of conveyor belts 24 with the mark camera 80. That is, the conveyor width is acquired. Then, it is confirmed whether or not the acquired conveyor width is a target conveyor width. When the acquired conveyor width is not the target conveyor width, the actual conveyor width is set to the target conveyor by operating the conveyor width changing mechanism 30 while imaging the pair of conveyor belts 24 by the mark camera 80. Change to width. Then, after the actual conveyor width becomes the target conveyor width, the mounting operation is started on the changed circuit board in S14.

  In S2 to S12, only the control device 90, the transport device 14, and the supply device fixing mechanism are operated, and the moving device 18 and the like are not operated. For this reason, the driving power source for operating the moving device 18 and the like is turned off after the end of S1, and turned on when the production start switch in S12 is turned on. Thereby, it is possible to ensure that the operation of the moving device 18 or the like is stopped during the setup change.

  Incidentally, in the above embodiment, the work machine 10 is an example of an anti-substrate work machine, and the transfer device 14 and the supply devices 20 and 22 constituting the work machine 10 are examples of the transfer device and the supply device. . The apparatus constituted by the mounting head 16 and the moving device 18 is an example of a substrate work execution apparatus. The conveyor width changing mechanism 30 is an example of an automatic setup changing mechanism, and the conveyor belt 24 is an example of a conveyor belt. The supply device fixing mechanisms 76 and 78 are an example of a switching mechanism. The display devices 86 and 88 are examples of a display device, and the setup change display area 102, the circuit board type selection area 104, and the operation button area 106 are examples of a display area, a board type input area, and a touch button area.

In addition, this invention is not limited to the said Example, It is possible to implement in the various aspect which gave various change and improvement based on the knowledge of those skilled in the art. Specifically, for example, in the above embodiment, while one supply device fixing mechanism is operating, the operation of the operation button 107 for operating the other supply device fixing mechanism is invalid. Even when one supply device fixing mechanism is in operation, the operation of the operation button 107 for operating the other supply device fixing mechanism can be made effective. With this configuration, it becomes possible for two operators to simultaneously operate the two supply device fixing mechanisms from the two display devices 86 and 88, and the setup change time can be considerably shortened. Specifically, as shown in FIG. 8B, while one operator operates the operation button 107 of the first display device 86, the first supply device is replaced and the setup is changed. Simultaneously with the setup change, another operator performs setup change to replace the second supply device while operating the operation button 107 of the second display device 88. Then, automatic changeover is performed simultaneously with the two manual changeovers. As a result, the setup change time becomes t ₃ , which can be approximately 1/3 of the conventional setup change time t ₁ .

  Moreover, although the working machine 10 of the said Example performed the mounting operation | work of the circuit component to a circuit board as a board | substrate operation | work, it is possible to employ | adopt the working machine which performs another board | substrate operation | work. . Specifically, for example, a work machine capable of performing an application operation for applying an adhesive to a circuit board, a solder printing operation for printing cream solder on the circuit substrate, an inspection operation for inspecting at least one of these operations, and the like. It is possible to adopt. In addition, when employ | adopting such a working machine, it is necessary to employ | adopt the working head according to each operation | work.

  Moreover, in the said Example, although the width change of the conveyor was performed as automatic setup change, various setup changes can be performed automatically. Specifically, for example, replacement of the mounting nozzle 34 attached to the work head 16 may be performed as an automatic setup change in order to cope with a change in the mounting component accompanying a change in the type of the circuit board. The automatic replacement of the mounting nozzle is a well-known technique, and therefore will be briefly described. A nozzle station that accommodates a plurality of mounting nozzles is provided on the base, and the work head 16 is moved onto the nozzle station. By moving the working head 16 in the vertical direction at that position, it is possible to automatically replace the mounting nozzle.

  Moreover, in the said Example, although supply apparatus was replaced | exchanged as manual setup change, various setup changes can be performed manually. Specifically, for example, the work head 16 attached to the Y-axis slider 58 may be replaced as a manual setup change in order to cope with a change in mounted parts accompanying a change in circuit board type. Moreover, you may perform replacement | exchange of the mounting nozzle accommodated in the nozzle station mentioned above as manual setup change. When such replacement of the work head, the mounting nozzle, etc. is adopted as manual setup change, the operator needs to access the inside of the work machine 10, so that the door of the work machine 10 is locked, It is desirable to employ a mechanism capable of switching between the unlocked state and the switching mechanism.
