<Working with substrate on work machine>
(A) Substrate Work in Independent Work Mode In the work machine 10, the circuit board 30 held by the pair of work heads 50 and 52 on the transfer devices 32 and 34 corresponding to the work heads 50 and 52, respectively, according to the configuration described above. On the other hand, it is possible to perform the mounting operation as the substrate operation independently. That is, it is possible to perform the mounting work in the independent work mode. Specifically, the first working head 50, a slider 63 to which the first working head 50 is attached, an X-axis direction slide device 64 that holds the slider 63 movably, and the X-axis direction slide device 64 are provided. A circuit board 30 in which the first mounting work execution device 130 configured by the Y-axis direction slide device 66 that is movably held holds the circuit components supplied by the first supply device 76 by the first transfer device 32. A first mounting operation to be mounted on the top is performed alone. On the other hand, the second working head 52, the slider 63 to which the second working head 52 is attached, the X-axis direction slide device 64 that holds the slider 63 so as to be movable, and the X-axis direction slide device 64 are movable. The second mounting work execution device 132 configured by the holding Y-axis direction slide device 66 mounts the circuit component supplied by the second supply device 78 on the circuit board 30 held by the second transport device 34. The second mounting operation is performed independently. Thus, in the independent work mode, each of the first mounting work and the second mounting work is performed independently.

  Since the first mounting operation and the second mounting operation are performed in substantially the same procedure, the first mounting operation will be described as a representative. In the first mounting work, first, the circuit board 30 is transported to the mounting work position by the first transport device 32 and the circuit board 30 is fixedly held at that position. Next, the first working head 50 is moved onto the circuit board 30 by the moving device 62, and the circuit board 30 is imaged by the mark camera 84. By the imaging, the type of the circuit board 30 and the holding position error of the circuit board 30 by the first transfer device 32 are acquired. A circuit component corresponding to the acquired type of the circuit board 30 is supplied by the tape feeder 80 of the first supply device 76, and the first working head 50 is moved by the moving device 62 to the supply position of the circuit component. As a result, the circuit component is sucked and held by the suction nozzle 54 of the first work head 50. Subsequently, the first work head 50 holding the circuit components is moved onto the parts camera 86 by the moving device 62, and the circuit components held by the first work head 50 are imaged by the parts camera 86. A holding position error of the circuit component is acquired by the imaging. Then, the first working head 50 is moved to the mounting position on the circuit board 30 by the moving device 62, and the mounting nozzle 54 is rotated based on the holding position error of the circuit board and the circuit component by the first working head 50. Later, circuit components are mounted.

  In the independent work mode, the first attachment work and the second attachment work similar to the first attachment work are performed in parallel, and two attachments to the two circuit boards 30 are performed. Work is done in parallel. Thereby, it is possible to construct a work machine with extremely high productivity. As shown in FIG. 4, an independent work mode execution unit 134 is provided in the controller 122 as a functional unit for executing the above work.

(B) Substrate Work in Cooperative Work Mode Further, in the work machine 10, the first mounting work execution device 130 and the second mounting work execution device 132 are coordinated so that the circuit board 30 held on one transfer device On the other hand, it is possible to perform mounting work. That is, unlike the independent work mode, the mounting work can be performed in the cooperative work mode. In the cooperative work mode, as shown in FIG. 5, the second work head 52 of the second mounting work execution device 132 is moved onto the circuit board 30 held by the first transport device 32, and the circuit board 30 is moved. Thus, the first mounting work execution device 130 and the second mounting work execution device 132 alternately perform the mounting work. That is, while the first mounting work execution device 130 is picking up the circuit components supplied by the first supply device 76, the second mounting work execution device 132 mounts the circuit components on the circuit board 30, and the second The first mounting work execution device 130 mounts the circuit component on the circuit board 30 while the mounting work execution device 132 is picking up the circuit component supplied by the second supply device 78.

  As described above, in the coordinated work mode, one of the pair of mounting work execution apparatuses 130 and 132 uses the time during which the circuit component is taken and the other mounts the circuit component on the circuit board 30. It is possible to build a system with very high work efficiency. As shown in FIG. 4, a cooperative work mode execution unit 136 is provided in the controller 122 as a functional unit for executing the above work.

<Screen display in each mode>
(A) Screen Display in Collaborative Work Mode In the collaborative work mode, the circuit components supplied by the first supply device 76 are applied to the circuit board 30 held on one transfer device by the first mounting work execution device 130. The second mounting work execution device 132 mounts the circuit components supplied by the second supply device 78 on the same circuit board 30. Under the situation where such mounting work is performed, the number of circuit components that can be supplied by the first supply device 76 and the number of circuit components that can be supplied by the second supply device 78 as the work progresses. For example, it may be expected that the circuit components that can be supplied by the second supply device 78 will disappear first. In such a case, for example, as shown in FIG. 6A, the first panel device 100 corresponding to the first mounting work execution device 130, that is, the first supply device 76 provided on the side. The display screen 104 of the panel device 100 displays that the number of circuit components that can be supplied by the first supply device 76 is small, and the second panel device 102 corresponding to the second mounting work execution device 132, that is, It is conceivable to display on the display screen 104 of the second panel device 102 provided on the second supply device 78 side that the number of circuit components that can be supplied by the second supply device 78 is reduced.

  When displayed in this way, when the operator is near the second supply device 78, the display screen of the second panel device 102 can be confirmed, and the shortage of circuit components of the second supply device 78 can be dealt with. When the operator is near the first supply device 76, it is possible to deal with the shortage of circuit parts of the first supply device 76 by checking the display screen of the first panel device 100, but the second supply device There is a possibility that the mounting operation may be interrupted because the circuit component of the second supply device 78 is lost because the circuit component shortage of 78 cannot be dealt with. In view of this, in the collaborative work mode, as shown in FIG. 6B, the display screen 104 of both the first panel device 100 and the second panel device 102 has high priority information, that is, 2 The fact that the number of circuit components that can be supplied by the supply device 78 is reduced is displayed. By displaying in this way, it becomes possible for the operator to check information with high priority regardless of which of the first supply device 76 and the second supply device 78 is used, and interrupting the mounting work, etc. It can be effectively avoided. In the cooperative work mode, as shown in FIG. 4, the cooperative work mode display unit 138 is provided in the cooperative work mode execution unit 136 as a functional unit for displaying as described above.

  In the cooperative work mode, only the switch of the panel device provided on the side of the device to be dealt with based on the displayed information is effective. That is, as shown in FIG. 6B, the number of circuit components that can be supplied by the second supply device 78 on the display screens 104 of both the first panel device 100 and the second panel device 102 is reduced. Is displayed, only the switch of the second panel device 102 provided on the second supply device 78 side is effective.

  More specifically, when dealing with a shortage of circuit components in the second supply device 78, it is necessary to replace the tape feeder 80 of the second supply device 78. For this reason, in order to remove the empty tape feeder 80 attached to the second supply device 78, the feeder release switch 112 of the second panel device 102 is operated. By this operation, the empty tape feeder 80 can be removed from the second supply device 78. After the empty tape feeder 80 is removed, a new tape feeder 80 is attached to the second supply device 78 and the feeder fixing switch 110 of the second panel device 102 is operated. By this operation, the new tape feeder 80 can be locked in the attached state to the second supply device 78. By exchanging the tape feeder in this way, the shortage of circuit components of the second supply device 78 can be solved. Note that while the switches 112 and the like of the second panel device 102 are valid, the devices and mechanisms do not operate even if the various switches 106 and 108 of the first panel device 100 are operated.

  However, the emergency stop switch 118 of each panel device 100, 102 is always valid regardless of the content displayed on the display screen. That is, as shown in FIG. 6B, even if information on the second supply device 78 is displayed on both the display screens 104, the first panel device 100 provided on the first supply device 76 side. The emergency stop switch 118 is enabled. This is because the work needs to be interrupted as soon as possible in an emergency, and when this switch is operated, the operations of the two mounting work execution devices 130 and 132 are stopped.

  The display information is not limited to circuit component shortage information, and various information related to the mounting work can be displayed. Specifically, for example, it is possible to display information such as mounting failure, supply failure, and image processing failure. When the operator needs to access the inside of the work machine based on the displayed information, the operation of the mounting work execution devices 130 and 132 to be dealt with based on the displayed information is stopped, and the front surface It is necessary to open the door 24. In this case, in order to stop the operation of the mounting work execution device, the mounting stop switch 106 of the panel device corresponding to the device is operated. By this operation, the second mounting work execution device 132 stops. Subsequently, the front door release switch 112 of the panel device is operated. By this operation, the front door 24 can be opened, and the operator can access the inside of the work machine. Then, after the handling by the operator is completed, the front door 24 is closed and the front door fixing switch 114 of the panel device is operated. By this operation, the front door 24 can be locked in the closed state. Then, by operating the mounting start switch 108 of the panel device, it is possible to restart the mounting work by the mounting work execution device that has been stopped. Incidentally, in the cooperative work mode, as shown in FIG. 4, as shown in FIG. 4, the cooperative work mode time switch dependence control unit 140 is a cooperative work mode execution unit 136 as a functional unit for relying on the switch to control each device. Is provided.

(B) Screen Display in Independent Work Mode In the collaborative work mode, information on the mounting work is displayed on the display screens 104 of both the first panel device 100 and the second panel device 102, so that the mounting work is effectively interrupted. Can be avoided. However, if the same display is performed in the independent work mode, the mounting work may be interrupted. Specifically, the number of circuit components that can be supplied by the first supply device 76 and the number of circuit components that can be supplied by the second supply device 78 are reduced, and the circuit components that can be supplied by the second supply device 78. Let's consider the case where is expected to disappear first. In such a case, as shown in FIG. 7A, when the lack of supply parts by the second supply device 78 is displayed on the display screens 104 of both the first panel device 100 and the second panel device 102, the operator Regardless of which display screen 104 is viewed, it is possible to know the shortage of supply parts by the second supply device 78, but not the shortage of supply parts by the first supply device 76. For this reason, the shortage of supply parts by the first supply device 76 cannot be dealt with, the circuit parts of the first supply device 76 are lost, and the mounting work by the first mounting work execution device 130 may be interrupted. This is because, in the independent work mode, two mounting operations are performed in parallel on the two circuit boards 30, and high priority information exists in each of the two mounting operations. is there.

  For this reason, in the independent work mode, as shown in FIG. 7B, high-priority information, that is, the first panel device 100 is displayed on each display screen 104 of the first panel device 100 and the second panel device 102. The display screen 104 displays the shortage of supply parts by the first supply device 76, and the display screen 104 of the second panel device 102 displays the shortage of supply parts by the second supply device 78. By displaying in this way, the operator can check high priority information of each of the two mounting operations performed in parallel, and effectively avoids interruption of each of the two mounting operations. It becomes possible. As shown in FIG. 4, the independent work mode display unit 142 is provided in the independent work mode execution unit 134 as a functional unit for displaying as described above in the independent work mode.

  Incidentally, in the independent work mode, the switches of the first panel device 100 and the second panel device 102 are valid. That is, as shown in FIG. 7B, when a shortage of supply parts by the corresponding supply devices 76 and 78 is displayed on the display screens 104 of the panel devices 100 and 102, the respective panel devices. The switches 100 and 102 are effective. As a result, it is possible to quickly respond to information with high priority in each mounting operation, and it is possible to effectively avoid interruption of each of the two mounting operations. In the independent work mode, as shown in FIG. 4, the independent work mode display unit 142 is provided in the independent work mode execution unit 134 as a functional unit for controlling each device depending on the switch as described above. It has been.

  Further, in the above description, there has been described a case in which supply parts 76 and 78 are short of supply parts, and supply panel shortage information is displayed on the two panel apparatuses 100 and 102. In some cases, supply parts shortage occurs in only one of the supply devices 76 and 78, and supply component shortage information is displayed only in the panel devices 100 and 102 corresponding to the supply device. In such a case, countermeasures such as replacement of the tape feeder 80 are performed on one of the supply devices, and the mounting operation execution device corresponding to the other supply device interrupts the mounting operation even during the countermeasures. It is designed to continue without being done.

  In the independent work mode, since two mounting operations are performed in parallel on the two circuit boards 30, only the mounting operation on one of the two circuit boards may be completed. In such a case, instead of the circuit board for which the mounting operation has been completed, the mounting operation may be performed on a circuit board of a different type from the circuit board. In that case, the front door 24 may be opened to replace the work head, the nozzle, etc. Even in such a case, the mounting work on the other of the two circuit boards is interrupted. Will continue without being done. However, when the operation is performed with the front door 24 opened, if the detection sensor 128 that detects danger reacts, the mounting operation on the other side is interrupted.

  Incidentally, in the above embodiment, the work machine 10 is an example of a substrate work machine, and the transfer devices 32 and 34 and the mounting work execution devices 130 and 132 that constitute the work machine 10 are the transfer device, and It is an example of the apparatus for board | substrate work execution. The control device 120 is an example of a control device. The control device 120 display unit 138 in the cooperative work mode, the switch in cooperative work mode switch control unit 140, the display unit 142 in independent work mode, and the switch in independent work mode. The dependency control unit 144 is an example of a cooperative work mode display unit, a cooperative work mode switch dependency control unit, an independent work mode display unit, and an independent work mode switch dependency control unit. Furthermore, the panel devices 100 and 102 are examples of display devices, and the mounting stop switch 106 and the mounting start switch 108 are examples of operation switches.

  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.
