<Mounting work with a mounting machine>
In the mounting machine 26, an electronic component mounting operation is performed on the circuit board held by the transfer device 32 with the above-described configuration. Specifically, according to a command from the controller 162 of the mounting machine 26, the circuit board is transported to the work position by the transport device 32 and is fixedly held at that position. The controller 162 transmits a component supply command to the control device 150 of the tape feeder 12, and the controller 152 of the control device 150 sends out the taped component and supplies the electronic component at the supply position in accordance with the received supply command. . Then, the mounting head 36 moves above the electronic component supply position, and sucks and holds the electronic component by the suction nozzle 70. Subsequently, the mounting head 36 moves above the circuit board and mounts the held electronic component on the circuit board.

<Error indication of tape feeder using visible light communication>
In the mounting machine 26, the electronic components are sequentially supplied from the tape feeder 12, whereby the mounting operation of the electronic components on the circuit board is executed. At this time, if an abnormality occurs in the tape feeder 12 and the supply of the electronic components is stopped, the mounting operation is stopped and the productivity is lowered. For this reason, in the tape feeder 12, the controller 152 monitors the operating state of the tape feeder 12, and when an abnormality occurs in the tape feeder 12, the red LED lamp 126 is turned on by a command from the controller 152. Thereby, the operator is notified that an abnormality has occurred in the tape feeder 12.

  Further, the controller 152 of the tape feeder 12 identifies the location where the abnormality has occurred. Specific abnormalities that occur in the tape feeder 12 include, for example, step-out of the electromagnetic motor 82, disconnection of wiring, sensor abnormality, and the like, and a specific abnormality occurrence point is specified. Then, the controller 152 indicates that the abnormality has occurred and detailed information regarding the specific location of the abnormality (hereinafter, may be referred to as “abnormality detailed information”) as a control device for the mounting machine 26. 160. When acquiring the abnormal detailed information, the control device 160 of the mounting machine 26 displays an image based on the information on the display panel 78 of the display device 37. As a result, the operator can recognize the specific occurrence location of the abnormality and perform a predetermined treatment on the location, thereby eliminating the abnormality of the tape feeder 12 and recovering the mounting work early. It becomes.

  However, when the manufacturer of the tape feeder 12 mounted on the mounting machine 26 is different from the manufacturer of the mounting machine 26, that is, when the tape feeder 12 is manufactured by a third vendor, the tape feeder 12 is used. When an abnormality occurs, only the fact that an abnormality has occurred is transmitted from the tape feeder 12 to the mounting machine 26, and detailed abnormality information is not transmitted from the tape feeder 12 to the mounting machine 26. Specifically, the manufacturer of the mounting machine 26 does not normally disclose detailed information on the design of the mounting machine 26, and third vendors provide detailed information on communication such as communication standards and communication protocols. Not available. For this reason, in the tape feeder 12 made by the third vendor, when an abnormality occurs in the tape feeder 12, only that an abnormality has occurred is transmitted to the mounting machine 26, and the detailed abnormality information is transmitted to the mounting machine 26. Not.

  As described above, if the detailed abnormality information is not transmitted to the mounting machine 26, the worker cannot identify the specific occurrence point of the abnormality. Therefore, the worker himself needs to investigate the occurrence point of the abnormality. Many problems arise, such as an increase in the burden on the device and a decrease in productivity due to a delay in the mounting work. For this reason, in the tape feeder 12, the abnormal detailed information is superimposed on the light of the LED lamp 126 using visible light communication and transmitted to the mobile terminal 14. Note that visible light communication is one type of wireless communication using light in the visible region, and as will be described later, visible light is transmitted as an optical signal. Then, the portable terminal 14 receives the light from the LED lamp 126 and displays an image based on the detailed abnormality information superimposed on the light, that is, a specific occurrence point of the abnormality on the display panel 180, so that the work is performed. The specific location where the abnormality has occurred is notified to the person.

  Specifically, the LED lamp 126 can modulate the frequency between several tens of Hz to several tens of MHz, and the light blinks according to the frequency. At this time, it is possible to superimpose an electric signal on the flashing light by regarding the flashing of the light as a “0” signal and a “1” signal. That is, by modulating the frequency according to predetermined information, the flashing light becomes an optical signal, and the flashing light functions as an electrical signal. For this reason, the flash pattern of the optical signal is stored in the controller 152 of the tape feeder 12 according to the abnormal detailed information.

  Specifically, for example, in the blinking pattern of the optical signal when the abnormality occurrence location is the electromagnetic motor 82, information indicating that the abnormality is occurring in the electromagnetic motor 82 and the abnormality of the electromagnetic motor 82 are resolved. The image data for displaying the information regarding the coping method for making it overlap is superimposed. In addition, for example, the blinking pattern of the optical signal when the abnormality occurrence location is a wiring relates to information indicating a specific arrangement location of the wiring in which the abnormality has occurred and a countermeasure for solving the wiring abnormality. Image data for displaying information is superimposed. In other words, the blinking pattern of the optical signal is superimposed with the abnormal detailed information and the image data for displaying information on the coping method for solving the abnormality corresponding to the information. The image data superimposed on the blinking pattern of the optical signal includes identification information for identifying the tape feeder 12, specifically, for example, a serial number.

  When a specific abnormality occurrence location is specified in the controller 152 of the tape feeder 12 storing such a flashing pattern of the optical signal, information on the specific occurrence location of the specified abnormality, that is, an abnormality A blinking pattern of the optical signal corresponding to the detailed information is determined. Then, the controller 152 outputs a command to the drive circuit 154 to blink the LED lamp 126 with the determined blink pattern. Thereby, the LED lamp 126 blinks in a predetermined blinking pattern. However, since the blinking pattern stored in the controller 152 is modulated to a frequency of several KHz or more, the LED lamp 126 blinks at a very high speed. Thereby, the worker cannot perceive the blinking of the LED lamp 126, and recognizes that the LED lamp 126 is lit without blinking.

  Then, when the LED lamp 126 is lit, the worker causes the portable terminal 14 to approach the LED lamp 126 and irradiates the image sensor 182 of the portable terminal 14 with light from the portable terminal 14. As a result, the image sensor 182 receives the light from the LED lamp 126. When the image sensor 182 receives the light from the LED lamp 126, the image sensor 182 converts the light into an electrical signal corresponding to the blinking pattern of the light. Then, the electrical signal is input to the controller 188 of the mobile terminal 14. That is, the image data for displaying the detailed abnormality information and information on the coping method for eliminating the abnormality corresponding to the information is input to the controller 188 of the mobile terminal 14.

  Then, the controller 188 outputs an image display command based on the input image data to the control circuit 190. As a result, the display panel 180 of the portable terminal 14 displays the detailed abnormality information, information on the coping method for solving the abnormality corresponding to the information, and the serial number of the tape feeder 12 in which the abnormality has occurred. The As described above, the detailed abnormality information is displayed on the display panel 180 of the mobile terminal 14 so that the operator can recognize the specific occurrence point of the abnormality and respond to the abnormality at an early stage. Become. In particular, the display panel 180 displays information on how to deal with the abnormality, so that appropriate processing can be performed on the abnormality, the abnormality of the tape feeder 12 can be eliminated, and the mounting operation can be performed. It is possible to recover early.

  Moreover, although the tape feeder 12 in which an abnormality has occurred can be recognized by the lighting of the LED lamp 126, many of the tape feeders 12 are mounted on the tape feeder holding base 100, and two of the plurality of tape feeders 12 are installed. In the case where abnormality occurs at the same time in two or more tape feeders 12, the information displayed on the display panel 180 indicates the information of any one of the two or more tape feeders 12 in which abnormality has occurred. There is a possibility that it cannot be recognized whether it is information. Therefore, the display panel 180 displays the serial number of the tape feeder 12 that is the transmission source of the information along with the abnormal detail information. As a result, the tape feeder 12 of information displayed on the display panel 180 can be properly recognized.

  Moreover, since the tape feeder 12 can transmit information to the portable terminal 14 using an existing configuration, the manufacturing cost can be suppressed as much as possible. Specifically, a conventional tape feeder is usually provided with an LED lamp 126 for notifying abnormality. For this reason, the controller of the conventional tape feeder stores the flashing pattern of the electrical signal according to the abnormal detailed information, and simply writes a program for flashing the LED lamp 126 according to the flashing pattern. The feeder 12 can be realized. That is, it becomes possible to transmit information to the portable terminal 14 without equipping a conventional tape feeder with a new communication mechanism or the like. Thereby, it becomes possible to suppress the manufacturing cost as much as possible and to add new performance to the conventional tape feeder.

  Moreover, since the portable terminal 14 is equipped with the image sensor 182 and receives light from the LED lamp 126 by the image sensor 182, the portable terminal 14 is a dedicated terminal used in the visible light communication system 10. However, since the image data is superimposed on the light of the LED lamp 126 of the tape feeder 12, it is not necessary to store special information or the like in the mobile terminal 14. Thereby, for example, when a portable terminal such as a commercially available smartphone is equipped with an image sensor or the like that can receive the light of the LED lamp 126 and convert the light into an electrical signal, It can be used together as a portable terminal used in the visible light communication system 10.

  The visible light communication system 10 is an example of a visible light communication system. The tape feeder 12 is an example of a work execution device. The mobile terminal 14 is an example of a mobile terminal. The mounting machine 26 is an example of a substrate working machine. The LED lamp 126 is an example of a lamp. The control device 150 is an example of a control device. The display panel 180 is an example of a display unit. The image sensor 182 is an example of a light receiving unit.

  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-described embodiment, the LED lamp 126 is employed as a lamp for lighting light used for visible light communication. However, the LED lamps 128 and 130 can be employed. That is, it is possible to employ a lamp for informing the operating state of the tape feeder 12. In addition, for example, a lamp for informing an operator of an instruction regarding the operation of the tape feeder 12, for example, a lamp for informing an instruction to replace a taped part, a lamp for lighting light used for visible light communication, etc. Can be adopted. In addition to LED lamps, various lamps such as halogen lamps, fluorescent lamps, mercury lamps, and organic EL lamps can be used as lamps for lighting light used for visible light communication.

  In the above embodiment, the image sensor 182 is employed as a light receiving unit that receives light and converts the light into an electric signal. However, a phototransistor, a photodiode, a photoelectric conducting cell, an O / E converter, etc. It is possible to adopt.

  In the above embodiment, the image data is superimposed on the light and transmitted from the tape feeder 12 to the portable terminal 14. However, the image data may be stored in the portable terminal 14. In this case, the image data corresponding to the abnormal detailed information and the data number are associated with each other and stored in the controller 188 of the mobile terminal 14. On the other hand, the controller 152 of the tape feeder 12 stores the specific occurrence location of the abnormality and the data number in association with each other. When a specific occurrence location of an abnormality is specified in the tape feeder 12, a data number stored in association with the occurrence location is specified, and information regarding the data number is obtained using visible light communication. Is transmitted to the mobile terminal 14. At this time, the portable terminal 14 specifies image data stored in association with the received data number, and displays an image based on the image data on the display panel 180. As described above, when the image data is stored in the portable terminal 14, it is possible to reduce the data amount of information superimposed on the light of the LED lamp 126.

  Moreover, in the said Example, although the information regarding the abnormality which generate | occur | produced in the tape feeder 12 is transmitted to the portable terminal 14 using visible light communication, for example, the information regarding the electronic component supplied with the tape feeder 12, Various information such as information on electronic components that can be supplied by the tape feeder 12 can be transmitted to the portable terminal 14 using visible light communication.
