The component mounting devices M1 to M3 have the same configuration, and the component mounting device M1 will be described here. In FIG. 2, a substrate transport mechanism 22 extending in the X direction is arranged at the center of the base 21. The board transfer mechanism 22 transports the board 23 carried in from the upstream side and holds it at a work position for executing the component mounting work. Parts supply units 24 are arranged on both sides of the board transfer mechanism 22. A plurality of tape feeders 25 are arranged side by side in the X direction in the component supply unit 24, respectively. The tape feeder 25 supplies the components to the component suction positions by the mounting head described below by pitch-feeding the carrier tape containing the components.

A Y-axis beam 26 having a linear drive mechanism is arranged along the Y direction at one end of the base 21 on one side in the X direction. Two X-axis beams 27, which also have a linear drive mechanism, are coupled to the Y-axis beam 26 so as to be movable in the Y direction. The X-axis beam 27 is arranged along the X direction.

A suction nozzle 28b (see FIG. 3) for sucking and holding parts is detachably attached to each lower end of the suction unit 28a.

By driving the Y-axis beam 26 and the X-axis beam 27, the mounting head 28 moves in the X direction and the Y direction. As a result, the two mounting heads 28 take out the parts from the parts suction positions of the tape feeder 25 of the corresponding parts supply unit 24 by the suction nozzle 28b, and transfer and mount the parts on the board 23 positioned by the board transfer mechanism 22. ..

A component recognition camera 29 is arranged between the component supply unit 24 and the substrate transfer mechanism 22. When the mounting head 28, which has taken out the parts from the parts supply unit 24, moves above the parts recognition camera 29, the parts recognition camera 29 images the parts held by the mounting head 28 and recognizes the holding posture of the parts. To do. The board recognition camera 30 is attached to the plate 27a to which the mounting head 28 is attached, and moves integrally with the mounting head 28.

The flow rate of air sucked from the suction nozzle 28b during vacuum suction and the flow rate of air discharged from the suction nozzle 28b during air blow are measured by the flow rate sensor 31. The measurement result of the flow rate sensor 31 is transmitted to the flow rate analysis unit 46 (see FIG. 5) for analysis.

When the suction nozzle 28b is vacuum-sucking the component P and more than a predetermined amount of air is flowing in, the flow rate analysis unit 46 does not have the component P in the suction nozzle 28b or is not sucked in the correct posture. It is judged that a suction error (abnormality) has occurred. Further, when the flow rate analysis unit 46 blows air to separate the component P from the suction nozzle 28b and mounts the component P on the substrate 23, if a predetermined air is not discharged (outflowed), the air supply source 34 fails or the suction nozzle 28b It is judged that an abnormality such as clogging has occurred.

Blinks based on (ST2). The component mounting device M1 shown in FIG. 6 is in a state in which the red lamp 37a is lit in this way.

When the component mounting devices M1 to M3 are not stopped due to an error (No in ST1), but there is a tape feeder 25 for which a component shortage notice will soon be given (Yes in ST3), the light emission control unit 48 has a yellow lamp 37b. Is turned on and blinks based on the conversion work machine information 44b (ST4), and the component mounting work is continued (returns to ST3). The component mounting device M3 shown in FIG. 6 is in a state in which the yellow lamp 37b is lit in this way. When there is no tape feeder 25 for which the parts shortage notice has been given (No in ST3), the light emission control unit 48 turns on the green lamp 37c (ST5), and the parts mounting work is continued (returns to ST1). The component mounting device M2 shown in FIG. 6 is in a state in which the green lamp 37c is lit in this way.

As described above, the work machine information acquisition system (parts mounting system 1) of the present embodiment includes at least one manufacturing work machine (parts mounting devices M1 to M3) for performing manufacturing work and a work machine related to the manufacturing work machine. It includes a first signal conversion unit 47 that converts information 44a into a blinking pattern of a light source, and a portable terminal T. Then, the manufacturing work machine has a collection unit (vacuum sensor 35, air pressure sensor 36, flow rate sensor 31 and flow rate analysis unit 46) that collects work machine information 44a, and a blinking pattern converted by the first signal conversion unit 47 (a blinking pattern (). It has a light emitting unit (notification light 37, touch panel 38, display 39, illumination light 41) that emits light from the conversion work machine information 44b).

Then, the mobile terminal T has a recognition unit (camera 12) that recognizes the blinking pattern (conversion work machine information 44b) emitted from the light emitting unit, and a second that converts the blinking pattern recognized by the recognition unit into the work machine information 44a. It has a signal conversion unit 14a and a display unit 11a for displaying the work machine information 44a (decoding work machine information 15a) converted by the second signal conversion unit 14a. As a result, the work machine information 44a can be displayed on the display unit 11a of the mobile terminal T by superimposing the image captured by the camera 12, and the worker can intuitively display the work machine (parts mounting). The devices M1 to M3) can be grasped.

The first signal conversion unit 47 may be provided in the management computer 3 in addition to the component mounting devices M1 to M3. In that case, the management computer 3 converts the work machine information 44a into the conversion work machine information 44b and transmits it to the component mounting devices M1 to M3. Further, the manufacturing work machine that performs the manufacturing work is not limited to the component mounting devices M1 to M3 that perform the component mounting work. For example, the manufacturing work machine may be an articulated robot that performs machine assembly work, a food manufacturing machine that performs food manufacturing work, or a semiconductor manufacturing apparatus that manufactures semiconductor parts.

Provided is a work machine information acquisition system that allows a worker to intuitively grasp a manufacturing work machine to be worked on.
