However, as shown in FIGS. 4 and 8, at least a part of the support plate 212 and the empty tray receiver 350 overlap in the width direction without interfering with each other. It is supported in the state. The cover 366 is rotated with respect to the empty tray receiver 350 and covers the rear portions of the empty tray receiver 350, the tray 210, and the support plate 212 as shown in FIG. 4, so that the operator does not touch them. To be done. While the empty tray receiver 350 is separated from the permanent magnet 410, the engagement member 356 is released from the engagement with the engagement portion 406 and is removed from the support members 152 and 154.

  When supplying electronic circuit components by the tape feeder 148, the cover support member 156 is attached to the positioning table 102, and the cover 430 is attached. Similarly to the tray support plate support member 150 and the like, the cover support member 156 is positioned by the positioning groove 120 and fixed to the positioning base 102 by the fixing device. After the predetermined tape feeder 148, tray 210, and empty tray receiver 350 are attached, the carriage 100 is moved to move the electronic circuit component supply device 18 and is attached to the electronic circuit component mounting system. At this time, the pair of positioned members 126 are lifted by a driving device (not shown) provided in the electronic circuit component mounting system, and a positioning pin (not shown) is fitted into the positioning hole 128, whereby the electronic circuit component supply device 18 is connected to the bed 10 in a positioned state.

  When electronic circuit components are mounted on the circuit board 12, the component suction head 62 is held by the head holding device 60, moved by the head moving device 32, and the electronic circuit components are taken out from the electronic circuit component supply device 18. 16 is moved to the circuit board 12. When electronic circuit components are supplied from the tray 210, if a plurality of trays 210 are stacked on the support plate 212, the electronic circuit components are taken out from the uppermost tray 210. When there are no more electronic circuit components, the tray 210 is accommodated in an empty tray accommodation box. In this case, the head holding device 60 is moved to the head storage device 64, the component suction head 62 is temporarily stored in the head storage device 64, and the empty tray removal head 452 is held. Then, the empty tray removal head 452 is moved onto the empty tray 210 and moved up and down, sucks the tray 210, lifts it, and moves it onto the upper opening 360 of the empty tray receiver 350. Open and put into the shooter unit 354. The loaded tray 210 is guided by the guide surface 364 and falls to the lower opening 362, and falls from the lower opening 362 to the empty tray storage box and is accommodated.

  The tray 210 that has been emptied is removed, and the height of the upper surface of the tray 210 that is positioned next to the uppermost stage is detected, and control of the descending distance of the component suction head 62 when the electronic circuit component is taken out. Used for etc. At the time of height detection, the head holding device 60 holds the height detection head. The detection of the height of the tray 210 by the tray height detection device is described in the specification of the Japanese Patent Application No. 2006-280081, and the description thereof is omitted.

  A case where the support plate 270 shown in FIG. 9 is attached to the positioning base 102 and the tray 210 is supported will be described. As shown in FIGS. 9 and 10, the support plate 270 has a width that can support two trays 210 side by side in the width direction and is supported by the support members 150, 152, and 154. The rail 220 has a width approximately equal to the width of the plate 212 and the empty tray receiver 350, and is located at a position corresponding to the support plate 212 and the support members 150 and 154 positioned to support the empty tray receiver 350, respectively. Is provided. In addition, since the empty tray receiver 350 is provided below the support plate 212 and does not interfere with the support plate 270, the type of the circuit board 12 on which the electronic circuit component is mounted changes, and when the setup is changed, the support plate If the support plate 212 is replaced with the support plate 270, the support plate 212 is removed from the support members 150 and 152. However, as shown in FIGS. 9 and 10, the support members 150, 152, and 154 and the empty tray receiver 350 are removed. The support plate 270 is supported by the tray support plate support member 150 and the empty tray receiver support member 154 so as to cover the entire empty tray receiver 350. Therefore, the labor required for the setup change can be reduced, and the process can be performed easily and quickly. The same applies when the support plate is changed from the support plate 270 to the support plate 212. The cover 366 is located behind the support plate 270 and covers the support plate 270 and the tray 210 from the rear.

  When the electronic circuit components are supplied by supporting the tray 210 on the support plate 270, if the electronic circuit components are also supplied by the tape feeder 148, there remains a space for providing another empty tray receiver on the positioning base 102. Instead, the empty tray is received by an empty tray receiver provided at a location different from the electronic circuit component supply device 18 of the electronic circuit component mounting system.

  When the support plate 272 shown in FIG. 11 is attached to the positioning base 102 and the tray 210 is supported to supply the electronic circuit components, the tape feeder 148 is not attached, and the electronic circuit components are supplied only by the tray 210. A wide empty tray receiver 368 is attached to the positioning base 102 together with the support plate 272. The support plate 272 is attached to the positioning base 102 by a tray support plate support member 150 and an empty tray receiving support member 152, and the empty tray receiver 368 is attached to the positioning base 102 by empty tray receiving support members 152 and 154. The tray support plate support member 150 and the empty tray receiving support member 154 are respectively positioned by the positioning grooves 120 at both ends, and the empty tray receiving support member 152 supports the end of the support plate 272 on the empty tray receiver 368 side, The positioning groove 120 is selected and positioned so as to support the end of the tray receiver 368 on the support plate 272 side.

  When the support plate 274 shown in FIG. 12 is attached to the positioning base 102 and electronic circuit components are supplied to the tray 210, the support plate 274 is a tray support plate attached to the positioning base 102 to support the support plate 272. It is supported by the support member 150 and the empty tray receiving support member 152. Therefore, when the change of the stage is performed and the state in which the tray 210 is supported by the support plate 272 and the electronic circuit component is supplied is changed to the state in which the tray 210 is supported by the support plate 274 and the electronic circuit component is supplied, the support is performed. Although the plate 272 is removed, the support members 150, 152, 154 and the empty tray receiver 368 are left attached to the positioning base 102, and the support plate 274 is attached to the empty tray receiver as shown in FIGS. It is supported by the support members 150 and 152 so as to cover a part thereof without interfering with 368. The remaining portion of the empty tray receiver 368 is opened upward, and the empty tray 210 is loaded. Even when the support plate supporting the tray 210 is changed from the support plate 274 to the support plate 272, it is only necessary to replace the support plate and the tray 210, and the setup can be easily and quickly changed.

  Thus, by selectively positioning the tape feeder 148, the tray support plate support member 150, and the empty tray receiving members 152, 154 in the positioning groove 120, the electronic circuit components are supplied only by the tape feeder 148, Alternatively, the configuration can be easily and quickly changed by using only the tray 210 or both, or by changing the number of trays 210 for supplying electronic circuit components or by providing an empty tray receiver 350. The electronic circuit component supply device 18 is obtained.
