  The operation based on the mounting data stored in the storage unit of the electronic component mounting apparatus main body 1 is as follows. First, the XY stage 12 is driven to bring the head unit 13 to the component supply unit 6 and then the mounting head 16 is moved down. A desired electronic component is picked up by the suction nozzle 18. Subsequently, after the mounting head 16 is raised, the XY stage 12 is driven to move the electronic component to the position directly above the component recognition camera 14, the electronic component is imaged, and recognition processing is performed by the recognition processing device 25. The positional deviation with respect to the suction nozzle 18 is recognized.

It is composed of two shutter mechanisms that make it possible to pick up parts.

  Next, a control block diagram of the electronic component mounting apparatus main body 1 of FIG. 2 will be described. Reference numeral 20 denotes a CPU (Central Processing Unit) as a control device that performs overall control of operations related to taking out and mounting of the electronic components of the electronic component mounting apparatus, 21 is a RAM (Random Access Memory) as a storage device, 22 Is a ROM (Read Only Memory), and the CPU 20 is an interface for operations related to taking out and mounting the electronic component of the electronic component mounting apparatus according to the program stored in the ROM 22 based on the data stored in the RAM 21. 23 and the drive circuit 24 are used to control each drive source.

  Reference numeral 25 denotes a recognition processing apparatus connected to the CPU 20 via the interface 23. The recognition processing of the image captured by the component recognition camera 14 and the image captured by the board recognition camera 17 and captured. The recognition processing device 25 performs the recognition process, and the processing result is sent to the CPU 20. That is, the CPU 20 outputs an instruction to the recognition processing device 25 to perform recognition processing (calculation of misalignment amount) on the image captured by the component recognition camera 14 or recognition processing of the image captured by the board recognition camera 17. In addition, the recognition processing result is received from the recognition processing device 25.

  That is, when the amount of displacement is grasped by the recognition processing of the recognition processing device 25, the result is sent to the CPU 20, and the CPU 20 drives the X-axis drive motor 12X and the Y-axis drive based on the result of the component recognition process and the board recognition process. By moving the suction nozzle 18 in the X and Y directions by driving the motor 12Y and by rotating the θ by the θ axis drive motor 18A, the rotational angle position around the X and Y directions and the vertical axis is not corrected, and the vertical axis drive motor The electronic component is lowered by 18B and mounted on the printed circuit board P.

  The image picked up by the component recognition camera 14 is displayed on a monitor 26 as a display device. The monitor 26 is provided with various touch panel switches 27, and various settings can be performed by an operator operating the touch panel switch 27.

  The touch panel switch 27 has a transparent conductive film coated on the entire surface of a glass substrate, and electrodes are printed on four sides. Therefore, when a very small current is passed through the surface of the touch panel switch 27 and an operator touches it, 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 21 as a switch unit for performing a certain operation, the operation is performed.

  The RAM 21 stores a plurality of production model information, that is, electronic component type information for each arrangement number of the component supply unit 6 as shown in FIG. 3, and work time information relating to various work times as shown in FIG. Etc. are stored. The model switching time in FIG. 4 is the time on the monitor 26 in order to select the time required for various operations associated with the model change when the type of the printed board P is changed, for example, the printed board P to be produced from now on. It is a work time for pressing the touch panel switch 27 and the like. The B / P rearrangement time is an operation time for inserting / removing a plurality of backup pins supporting the printed circuit board P on the upper surface of the set table 8 according to the printed circuit board P to be produced. The feeder replacement time is an operation time for removing or attaching the component supply unit 6 from the unit base 19 according to the printed circuit board P to be produced from now on, and is a replacement time for one component supply unit 6. The number of workers is the number of workers.

  The above-described model switching time, B / P rearrangement time, feeder replacement time, and number of people can be set by operating the touch panel switch 27 while the operator looks at the screen displayed on the monitor 26. The setting data is stored in the RAM 21.

  There are two types of the component supply unit 6: a single lane feeder and a dual lane feeder. In this embodiment, the arrangement numbers 0002 and 0003 are the arrangement positions of one dual lane feeder (the others are single lane feeders). This data is stored in the RAM 21 in advance. Also, the feeder replacement time is set to be long including the replacement time of the supply reel, and the calculation and display of the setup time will be described based on FIG. 5 with the above configuration.

  First, the operator presses the touch panel switch 27 on the screen displayed on the monitor 26 to perform an operation accompanied with the model switching of the printed circuit board P, and selects a type of the printed circuit board P to be newly produced. Then, the CPU 20 reads the production model information of the old printed circuit board P that has been produced and stored in the RAM 21 and the new printed circuit board P that will be produced, that is, the production model A (old printed circuit board) as shown in FIG. The component type is compared with the component type of the production model B (new printed circuit board) to determine whether there is a change in the arrangement of the component supply unit 6 in the order of the arrangement number. First, since the arrangement number 0001 is the electronic component type 01 for both, the component supply unit 6 is not replaced, and the arrangement numbers 0002 and 0003 are changed from the component 02 to the component 05. (Dual lane feeder) 6 has been replaced, and a counter (not shown) increments the number of replacement of the component supply unit by “1”, and thereafter repeats for each supply unit 6 until arrangement number 0005. As a result, the count value of the counter is “3”, and the parts supply unit is replaced three times.

  Next, after counting the number of replacements of the component supply unit 6 by comparing the component type of the production model A and the component type of the production model B, the CPU 20 calculates the setup time. That is, the CPU 20 is set and stored in the RAM 21, and based on each vice minister shown in FIG. 4, the model switching time 60 seconds, the B / P rearrangement time 40 seconds, the feeder replacement time 450 seconds (150 seconds × counter) And the total value of 550 seconds is divided by two people. Accordingly, the setup time per person is 275 seconds, and the CPU 20 displays the setup time on the monitor 26.

  Therefore, one of the workers can determine whether it is appropriate to perform the setup change by two persons judging from the production plan while looking at the screen displayed on the monitor 26.

  In the previous embodiment, the feeder replacement time is set longer including the replacement time of the supply reel. However, as another embodiment, the feeder replacement time does not include the replacement time of the supply reel. FIG. 3, FIG. 6 and FIG. 7 show an embodiment in which the feeder replacement time and the supply reel replacement time are separately set as work time for removing or attaching the component supply unit 6 from the unit base 19 according to This will be explained based on. As a premise of this embodiment, as the work time, in addition to the model switching time, B / P rearrangement time, feeder replacement time and number of people of the previous embodiment, the supply reel replacement time is set as described above, The following description assumes that the arrangement numbers 0002 and 0003 are the arrangement positions of one dual lane feeder (the others are single lane feeders).

  First, the operator presses the touch panel switch 27 on the screen displayed on the monitor 26 to perform an operation accompanied by the model switching of the printed circuit board P, and selects a type of the printed circuit board P to be newly produced. Then, the CPU 20 reads the production model information of the old printed circuit board P that has been produced and stored in the RAM 21 and the new printed circuit board P that will be produced, that is, the production model A (old printed circuit board) as shown in FIG. The component type is compared with the component type of the production model B (new printed circuit board) to determine whether there is a change in the arrangement of the component supply unit 6 in the order of the arrangement number. First, since the arrangement number 0001 is both the component 01, the component supply unit 6 is not replaced, and the arrangement numbers 0002 and 0003 are changed from the component 02 to the component 05, so that the component supply unit 6 is replaced. The first counter (not shown) increments the number of replacements of the component supply unit 6 by “1”.

  Next, in addition to the replacement of the component supply unit 6, the CPU 20 determines whether or not to replace the supply reel in order to change to a storage tape that stores different electronic component types. If there is no replacement of the supply reel, that is, only the arrangement change of the component supply unit 6 is repeated for each supply unit 6 until the arrangement number 0005 in the same manner, but if there is a replacement of the supply reel, this is the single. If there is only one supply reel of the lane feeder or dual lane feeder, the second counter is incremented by "1", if it is two supply reels of the dual lane feeder, it is incremented by "2", and so on until arrangement number 0005 is repeated. .

  Here, as a result, when the component supply unit 6 that is a dual lane feeder that handles the component 05 is changed to the arrangement number 0002 and both the supply reels are changed, the count value of the first counter is “ 3 ”, the count value of the second counter is“ 4 ”.

  Next, after counting the number of replacements of the component supply unit 6 and the number of replacements of the supply reel by comparing the part type of the production model A and the part type of the production model B, the CPU 20 calculates the setup time. That is, the CPU 20 is set and stored in the RAM 21 based on each time shown in FIG. 7, the model switching time 60 seconds, the B / P rearrangement time 40 seconds, and the feeder replacement time 180 seconds (60 seconds × first time). 1 counter count value “3”) and supply reel exchange time 320 seconds (80 seconds × second counter count value “4”) are totaled, and the total value 600 seconds is divided by two people. Accordingly, the setup time per person is 300 seconds, and the CPU 20 displays the setup time on the monitor 26.

  Therefore, one of the workers can determine whether it is appropriate to perform the setup change by two persons judging from the production plan while looking at the screen displayed on the monitor 26.

  Various kinds of setup change operations required for switching the printed circuit board model are not limited to those described in FIGS. 4 and 7, and other operations such as changing the conveyor width of the conveyor unit 3 according to the size of the printed circuit board. Work may be included, and the total work time is divided by the number of workers, and the setup time per person is displayed on the display device. However, the total work time before dividing by the number of workers is It may be displayed.

  In addition, the total time required for various setup change operations required when switching the type of printed circuit board may be calculated and displayed by a personal computer other than the electronic component mounting apparatus.

  Furthermore, although a so-called multi-function chip mounter has been described as an example of the electronic component mounting apparatus, the present invention is not limited to this and may be applied to a high-speed chip mounter such as a rotary table type. In addition, the present invention is not limited to an electronic component mounting device, but is a working device for assembling other electronic components, for example, a printing machine such as a screen printer for applying solder cream on a printed board, and an adhesive on the printed board. The present invention can also be applied to an adhesive application device that applies the slag.

  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, and the present invention is not limited to the various embodiments described above without departing from the spirit of the present invention.
