The electronic components loaded in the formed storage portion are sequentially supplied to the component suction and take-out position, and suction as a holding means is performed from the tip portion. It can be taken out by the nozzle.

  Each electronic component mounting apparatus 1 includes a control microcomputer (hereinafter abbreviated as “microcomputer”) 2 for overall control of operations related to component mounting operation for mounting electronic components on the printed circuit board P, and the like. A display device 3 such as a monitor and an input device 4 composed of, for example, a touch panel switch displayed on the monitor are connected to the microcomputer 2 via a LAN line 6. Further, a communication interface 5 is connected to each of the microcomputers 2, and the microcomputers 2 can transmit and receive via the communication interface 5 and the LAN line 6.

  The microcomputer 2 includes a CPU (Central Processing Unit) as control means, a ROM (Read Only Memory) for storing programs, and a RAM (Random Access Memory) as storage means. Based on the data stored in the RAM, the operation related to component mounting is controlled according to the program stored in the ROM.

  The RAM stores mounting data indicating mounting coordinates of electronic components on the printed circuit board P for each mounting order, component library data that is characteristic of the electronic components, line registration device list data, and the like. As shown in FIG. 2, the line registration device list data includes a device number, a device host name (IP address), and a device type (model) of the electronic component mounting device 1.

  The RAM stores the configuration of a group of devices that can manage the control of starting the mounting operation in the board assembly / mounting line in the order of arrangement in the board assembly / mounting line.

  With the above configuration, the mounting operation of the electronic component will be briefly described. First, in the flowchart of FIG. 3, the work manager, for example, a work manager of any of the four units in order to start the mounting operation of each device in the manageable device group in the board assembly / mounting line. When the line start switch portion 4C of the input device 4 of the third electronic component mounting apparatus 1 is pressed from the left (upstream side) of the board assembly mounting line near itself, the electronic component mounting apparatus 1 is pressed (step S1). The microcomputer 2 reads the line registration device list data stored in its own RAM (step S2).

  That is, “production operation” is selected by the pressing operation of the production operation start switch unit 4S on the screen displayed on the display device 3 of the third electronic component mounting apparatus 1 from the left, and the local switch unit 4A is pressed. When the line switch unit 4B is pressed from the state where “local” is selected, the screen changes from FIG. 7 to FIG. 8, and when the line start switch unit 4C is pressed in this state (step S1), The microcomputer 2 of the electronic component mounting apparatus 1 reads line registration device list data stored in its own RAM (step S2).

  The local switch unit 4A is for selecting that the electronic component mounting apparatus 1 is to perform a predetermined operation independently, and the line switch unit 4B performs the predetermined operation on all manageable device groups in the board assembly / mounting line. It is for choosing what to do.

  Then, the microcomputer 2 of the third electronic component mounting apparatus 1 from the left sets n = 1 (step S3), and transmits a start command to the nth electronic component mounting apparatus 1 (step S4). That is, a start command is transmitted from the microcomputer 2 of the third electronic component mounting apparatus 1 from the left to the first, that is, the leftmost electronic component mounting apparatus 1 (the microcomputer 2).

  After the start command is transmitted, the microcomputer 2 of the third electronic component mounting apparatus 1 from the left determines whether or not communication is possible (step S5). In this case, the power supply of the leftmost electronic component mounting apparatus 1 is off (OFF), or the microcomputer 2 of the third electronic component mounting apparatus 1 from the left and the microcomputer 2 of the leftmost electronic component mounting apparatus 1 If there is a trouble in the communication path between them, it is determined that communication is impossible, and as shown in the line start abnormality screen of FIG. 6, a message indicating that communication is impossible is displayed on its own display device 3 (step S6). FIG. 6 shows an example in which the second electronic component mounting apparatus 1 from the left is displaying an abnormal communication failure.

  If it is determined in step S5 that communication is not possible by the microcomputer 2 of the third electronic component mounting apparatus 1 from the left, or if communication is impossible in step S6, the display device 3 displays an abnormality indicating that communication is not possible. “1” is added to the above-mentioned n = 1 (step S7), and it is determined whether or not this “1 + 1” “2” is larger than the registered number “4” (step S8). If determined not to be large, the microcomputer 2 of the third electronic component mounting apparatus 1 from the left transmits a start command to the second electronic component mounting apparatus 1 from the left (step S4).

  Then, after the start command is transmitted, the microcomputer 2 determines whether or not communication is possible (step S5). In this case, the second electronic component mounting apparatus 1 from the left is turned off (OFF), or the microcomputer 2 of the third electronic component mounting apparatus 1 from the left and the second electronic component mounting apparatus from the left If there is a trouble in the communication path with one microcomputer 2, it is determined that communication is impossible, and a message indicating that communication is not possible is displayed on its own display device 3 (step S6).

  If it is determined in step S5 that communication is not possible by the microcomputer 2 of the third electronic component mounting apparatus 1 from the left, or if communication is impossible in step S6, the display device 3 displays an abnormality indicating that communication is not possible. “1” is added to the aforementioned n = 2 (step S7), and it is determined whether or not the 2 + 1 “3” is larger than the registered number “4” (step S8). If it is determined that it is not large, the third electronic component mounting apparatus 1 from the left transmits a start command to itself (step S4).

  In this case, the third electronic component mounting apparatus 1 from the left determines that communication with the microcomputer 2 is not possible within itself (step S5), or communication with the display device 3 is impossible when communication is impossible in step S6. When an abnormality is displayed, “1” is added to the above-mentioned n = 3 (step S7), and it is determined whether or not this “3 + 1” “4” is larger than the registered number “4” (step S8). If it is determined that the number is not larger than the registered number “4”, the microcomputer 2 of the third electronic component mounting apparatus 1 from the left transmits a start command to the fourth electronic component mounting apparatus 1 from the left. (Step S4).

  In step S5, the microcomputer 2 of the fourth electronic component mounting apparatus 1 from the left determines that communication is not possible, or if communication is not possible in step S6, the display apparatus 3 displays a message indicating that communication is not possible. Then, “1” is added to the above-mentioned n = 4 (step S7), and it is determined whether or not “5” of 4 + 1 is larger than the registered number “4” (step S8). If it is determined that it is not greater than ", the flowchart of the electronic component mounting apparatus 1 on the third transmission side from the left in FIG. 5 ends.

  Next, the flowchart of the electronic component mounting apparatus 1 on the receiving side in FIG. 4 will be described. First, as described above, from the microcomputer 2 of the third electronic component mounting apparatus 1 from the left, other than that, When the electronic component mounting apparatus 1 receives the start command (step S11), the microcomputer 2 of the received electronic component mounting apparatus 1 checks whether the mounting operation can be started (startable) (step S12).

  That is, the received microcomputer 2 of the electronic component mounting apparatus 1 is, for example, that the arrangement of the component supply unit on the feeder base is different from the arrangement data, or that the arrangement of the suction nozzles provided in the installation head is different from the arrangement data. If the mounting data is incorrect, it is determined that the mounting operation cannot be started.

  By this check, the microcomputer 2 of the received electronic component mounting apparatus 1 determines whether or not it can start the mounting operation (step S13). If it is determined that the start cannot be started, the left side from which the start command is transmitted is determined. A response indicating that the start operation cannot be started is returned to the third electronic component mounting apparatus 1 (step S14). As shown in FIG. 5, the response content indicating that the start is impossible is the device number and state of the electronic component mounting device 1, * 1 means that the mounting operation cannot be started, and * 2 has already stopped. If you are stopped.

  When the electronic component mounting apparatus 1 that has received the start command returns a response indicating that the mounting operation cannot be started to the third electronic component mounting apparatus 1 from the left from which the start command has been transmitted, the response shown in FIG. As shown in the line start abnormality screen, the third electronic component mounting apparatus 1 is mounted by the electronic component mounting apparatus (for example, the fourth from the left) that has returned a response indicating that the start cannot be made to its own display device 3. Is displayed indicating that the start cannot be started.

  If it is determined by the check that the microcomputer 2 of the received electronic component mounting apparatus 1 can be started (step S13), the tower lamp is turned on and the buzzer is turned on for 3 seconds. Thereby, the work manager is notified that the received electronic component mounting apparatus 1 starts the mounting operation, and the work manager can confirm that fact (step S15).

  The electronic component mounting apparatus 1 that receives this notification starts mounting operation or waits for the printed circuit board. The start of the mounting operation is the start of a mounting operation such as taking out an electronic component from the component supply unit or mounting an electronic component on the printed circuit board. Waiting for the printed circuit board means that the printed circuit board has reached the positioning unit. Then, it means a state where the mounting operation can be started at any time.

  As described above, according to the present invention, even if there is an electronic component mounting apparatus 1 that is a plurality of work apparatuses in the board assembly and mounting line, the mounting operation of other work apparatuses can be started in any work apparatus. Thus, the work manager's work can be reduced.

  6 is displayed on the display device 3 of the third electronic component mounting apparatus 1 from the left, the display device 3 of the third electronic component mounting apparatus 1 is displayed. However, the present invention is not limited to this, and may be distributed to all the electronic component mounting apparatuses 1 and the like in the board assembly / mounting line or a specific electronic component mounting apparatus 1 and displayed on those display apparatuses.

  Then, in the electronic component mounting apparatus 1 constituting the board assembly / mounting line as described above, when the mounting operation of the electronic component to the printed board starts, the printed board is first inherited from the upstream apparatus (not shown). If it is peeled and exists on the substrate supply unit of the transfer device, the printed circuit board on the substrate supply unit is moved to the substrate positioning unit to be positioned and fixed. When the printed circuit board is positioned, the beam provided on the electronic component mounting apparatus 1 moves in the Y direction by driving the Y direction linear motor, and the mounting head provided on the beam by the X direction linear motor moves in the X direction. To the upper position of the component take-out position of the corresponding component supply unit, and the suction nozzle provided in the mounting head is lowered by driving the vertical axis motor to take out the electronic component from the component supply unit.

  After removal, the suction nozzle of the mounting head is raised, the beam mounting head is passed over the component recognition camera, and a plurality of electronic components sucked and held by the plurality of suction nozzles during the movement are collectively displayed. The image is picked up, and the picked-up image is recognized by the recognition processing device to grasp the positional deviation with respect to the suction nozzle.

  Each mounting head is provided with a substrate recognition camera, images a positioning mark attached to the printed circuit board on which the substrate recognition camera moved to the upper position of the printed circuit board is positioned, and recognizes the captured image. Recognizes the position of the printed circuit board through recognition processing.

  Then, the electronic component is mounted on the printed board while the suction nozzle corrects the positional deviation by adding the recognition processing result of the positioning mark of the printed circuit board and each component recognition processing result to the mounting coordinates of the mounting data. In this way, when all the electronic components are mounted on the printed board, the electronic components are mounted on the printed board so that the printed board is transferred from the board positioning unit to the downstream device via the board discharging unit. The operation ends.

  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 alternatives described above without departing from the spirit of the present invention. It includes modifications or variations.
