  FIG. 2 is a control block for control related to electronic component mounting of the electronic component mounting apparatus 1 and will be described below. Each element of the electronic component mounting apparatus 1 is centrally controlled by a CPU (Central Processing Unit) 21 and stores a ROM (Read Only Memory) 22 for storing a program related to this control and various data. A RAM (Random Access Memory) 23 is connected via a bus line 24. Further, a monitor 25 as a display device for displaying an operation screen and the like and a touch panel switch 26 as an input means formed on the display screen of the monitor 25 are connected to the CPU 21 via an interface 27. The Y-direction linear motor 9 and the like are connected to the CPU 21 via a drive circuit 28 and an interface 27.

  In the RAM 23, for each mounting order, mounting data including X direction, Y direction and angle information of mounting coordinates of each electronic component in the printed circuit board P, arrangement number information of each component supply unit 3B, and the like. Is stored. The RAM 23 stores information on the type of each electronic component corresponding to the arrangement number of each component supply unit 3B. Further, for each component ID, a component library relating to characteristics such as the size and feed pitch of the electronic component. Data is stored.

  A transparent conductive film is coated on the entire surface of the glass substrate of the monitor 25, and electrodes are printed on four sides. Therefore, when a very small current is passed through the surface of the touch panel and the operator touches, a current change occurs in the electrodes on the four sides, and the coordinate value touched by the circuit board connected to the electrodes is calculated. Therefore, if the coordinate value matches the coordinate value in the coordinate value group stored in advance in the RAM 23 as a predetermined switch portion of the touch panel switch 26 that performs a certain operation, the operation is performed.

  A recognition processing device 29 is connected to the CPU 21 via the interface 27. The recognition processing device 29 performs recognition processing of an image captured by the board recognition camera 8 or the component recognition camera 12. The processing result is sent to the CPU 21. That is, the CPU 21 performs recognition processing (calculation of the amount of displacement of the electronic component sucked and held by the suction nozzle 18 or the position of the printed board P positioned) by the image captured by the board recognition camera 8 or the component recognition camera 12. An instruction is output to the recognition processing device 29 and a recognition processing result is received from the recognition processing device 29.

  With the above configuration, when the setup change is completed and the electronic component mounting apparatus 1 is automatically operated, the first printed board P is transported from the upstream apparatus to the board positioning unit by the transport apparatus 2, and is positioned and fixed by the positioning mechanism. The

  Next, each mounting head 6 moves in accordance with the mounting data stored in the RAM 23, and the electronic component to be mounted by the suction nozzle 5 corresponding to the component type of the electronic component is picked up and taken out from the predetermined component supply unit 3B. More specifically, the suction nozzle 5 of the back mounting head 6 provided on the back beam 4A moves so as to be positioned above a predetermined component supply unit 3B, but the Y direction linear motor 7 drives in the Y direction. Then, the beam 4A is moved, the X direction linear motor 9 is driven in the X direction, and the mounting head 6 on the back side is moved. The component supply unit 3B has already been driven by the feed motor and the peeling motor, and the component suction is performed. Since the component can be taken out at the take-out position, the vertical axis motor 10 lowers the suction nozzle 5 to pick up and take out the electronic component, and then the mounting head 6 on the back side moves up.

  Next, the mounting head 6 on the back side moves above the next component supply unit 3B, and the vertical axis motor 10 lowers the next suction nozzle 5 to pick up and take out the electronic components, and the mounting head 6 moves up. As described above, the electronic components are taken out and held by suction by the twelve suction nozzles 5 of the mounting head 6 on the back side.

  Then, the mounting head 6 on the back side moves so as to mount the electronic component at a predetermined position on the printed circuit board P positioned by the substrate positioning unit. While moving the mounting head 6, the component recognition is performed while moving. The electronic component sucked and held by each suction nozzle 5 when passing the upper position of the camera 8 is imaged by the component recognition camera 10 (fly recognition).

  Based on this imaging result, the recognition processing device 29 recognizes how much the electronic component is displaced and held with respect to the suction nozzle 5 by the recognition processing device 29, and the Y-direction linear motor 7 is recognized. The suction nozzle 5 that holds the electronic component by driving the X-direction linear motor 9 moves to the printed circuit board P.

  Then, before mounting the electronic component on the printed circuit board P, the recognition mark M1 attached to the printed circuit board P by the substrate recognition camera 12 provided on the mounting head 6 attached to one beam 4A for mounting the electronic component. , M2 is picked up, and the image picked up by the board recognition camera 12 provided in the mounting head 6 on the back side is recognized by the recognition processing device 29. The position recognition result of the printed board P and each electronic component The Y direction linear motor 7, the X direction linear motor 9, and the θ axis motor 11 are corrected and controlled by the CPU 21 in consideration of the position recognition processing result, and each suction nozzle 5 of the mounting head 6 on the back side corrects the positional deviation. Meanwhile, each electronic component is mounted at a predetermined position on the printed circuit board P.

  Next, the electronic components are taken out from the component supply unit 3B by the suction nozzle 5 of the mounting head 6 provided on the front beam 4B, and each electronic component is mounted at a predetermined position on the printed circuit board P as described above. Is done.

  Similarly, by mounting the electronic components up to the last step number on the printed circuit board P, the mounting operation on the first printed circuit board P is completed, and the printed circuit board P is discharged to the downstream apparatus.

  Then, the mounting operation of the electronic component mounting apparatus 1 is stopped, and the work manager presses the touch panel switch 26 displayed on the monitor 25 to display the screen shown in FIG. 26 of the production switch unit 30 for production, the setup switch unit 31 for performing various setups, and the maintenance switch unit 32 for performing maintenance, for example, pressing the setup switch unit 31 Then, CPU21 switches a screen and displays a screen as shown in FIG.

  FIG. 4 is a screen for instructing where to move the printed circuit board P, and shows a schematic diagram of the transport device 2, both of which are provided to the substrate supply unit 2 </ b> A of the transport device 2 that is the touch panel switch 26. A board supply switch section 33 corresponding to the board positioning switch section 34 corresponding to the board positioning section 2B, a board discharging switch section 35 corresponding to the board discharging section 2C, and a switch section 36 for returning to the lower right portion of the screen are also provided. ing.

  Here, when the setup switch unit 31 is pressed while the screen shown in FIG. 3 is displayed, the screen is switched to a screen as shown in FIG. 4. In this switched screen, the printed board P is moved from where to where. After instructing whether or not to perform, when the return switch unit 36 is pressed, the screen is switched to the screen shown in FIG.

  However, a shutdown switch unit 37 for cutting off the power supply of the electronic component mounting apparatus 1 is provided in the screen of FIG. 3 at the same position as the return switch unit 36 in the lower right part of the screen of FIG. When the return switch unit 36 is quickly pressed twice on the screen shown in the figure, the conventional switching results from FIG. 4 to FIG. 3 and the shutdown switch unit 37 has been pressed. In some cases, an unintended instruction is executed that the power of the component mounting apparatus 1 is turned off. However, the present invention is controlled as shown in FIG. 5 and FIG. It will be made so that no serious situation occurs.

  That is, any one of the touch panel switches 26 is pressed to be turned on (on, hereinafter the same), and when the pressing is stopped and released, the touch panel switch 26 is turned off (off, hereinafter the same). When this is turned off, the timer 40 is started to start timing, and the touch panel switch 26 is pressed against the RAM 23 as a memory (the state immediately after the touch panel switch 26 is pressed). Store. In this case, when the touch panel switch 26 is pressed and turned on, the timer 40 starts to start timing, and the fact that the touch panel switch 26 is pressed is stored in the RAM 23 which is a memory. Also good.

  Then, when the timer 40 has timed and the time has expired and the time is up, the CPU 21 stops the timer 40 and clears the timed contents, and also clears the contents stored in the memory (RAM 23) and ends. To do.

  Here, when the touch panel switch 26 is pressed and turned on, and when the pressure is stopped and released, the touch panel switch 26 is turned off. If the second press is performed immediately thereafter, the storage state of the RAM 23, that is, the touch panel switch 26 is pressed. The CPU 21 determines whether or not it is stored.

  In this case, it is stored that the touch panel switch 26 is in a pressed state before the timer 40 expires. Therefore, even if the second press is made continuously, the CPU 21 does not change the second time. The instruction based on the pressure is ignored and the instruction is not executed.

  For this reason, even if the touch panel switch 26 is pressed quickly before the timer 40 expires, an instruction based on the second and subsequent pressing operations is not executed, so that an unintended instruction can be prevented from being executed.

  Therefore, as in the prior art, after the pressing operation of the return switch unit 36 by the pressing operation multiple times by quick pressing, the screen is switched to the screen shown in FIG. 4 and the shutdown switch unit 37 at the same position is pressed. Thus, it is possible to prevent a situation in which an unintended instruction is executed that the power of the electronic component mounting apparatus 1 is turned off.

  Further, if another touch panel switch 26 is pressed after a lapse of a predetermined time after the timer 40 has counted, the RAM 23 indicates that the touch panel switch 26 has been pressed by the CPU 21 when the predetermined time elapses. Since it is cleared, an instruction based on the pressing operation of another touch panel switch 26 is executed.

  In the above embodiment, the touch panel switch 26 has been described as an example. However, the present invention is not limited to this touch panel switch, and an operation based on a mouse as an instruction unit performs the same control as described above, and an unintended instruction is executed. The situation can be prevented from occurring.

  That is, even when the button (switch) displayed on the monitor 25 is moved with the mouse, the click is quickly pressed, and repeated several times in succession, if the timer 40 is not timed out, the mouse By storing in the RAM 23 the state immediately after being clicked on, the CPU 21 ignores the instruction based on the second and subsequent clicks based on the contents stored in the RAM 23 and does not execute the instruction. It can also be done.

  Although the embodiments of the present invention have been described above, various alternatives, modifications, and variations can be made by those skilled in the art based on the above description. It encompasses alternatives, modifications or variations.
