The electronic component is mounted in a predetermined direction (angle) at a predetermined position of the printed circuit board P.

  In this case, in the left part of the electronic component mounting apparatus 1, the front and rear beams 10 and the suction nozzle 7 of the mounting head 6 moving along each beam 10 mount the electronic component on the left printed board P. In the right part, the front and rear beams 10 and the suction nozzle 7 of the mounting head 6 moving along each beam 10 mount the electronic component on the right printed board P.

  Due to the production of these electronic component mounting apparatuses 1, it is necessary to supply components to the component supply unit 5.

  When component replenishment is required, the electronic component mounting device 1 is displayed, and the switch between the corresponding component supply device 3 and the electronic component mounting device 1 is released by the switch operation, and the component supply unit 5 that needs component replenishment is removed. It can be extracted from the feeder base 14 at the upper part of the component feeder frame 4.

  The component supply unit 5 that has been removed because it needs to be replenished is placed on the component supply unit mounting table 21 and replenished, that is, the tape of the new tape reel 18 is connected to the component supply unit 5, and then The component supply unit 5 is extracted from the component supply unit mounting table 21 and set on the original feeder base 14, and the tape reel 18 connected to the component supply unit 5 is placed below the component supply device frame 4, and a switch operation is performed. The relevant component supply device 3 and the electronic component mounting device 1 are clamped, and the production returns to the electronic component mounting device 1.

  Alternatively, by preparing the component supply unit 5 with the same component supply time and the component supply unit 5 supplied with the same component on the component supply unit mounting table 21 in advance, the electronic component mounting apparatus 1 can be manufactured. It is possible to quickly replace the component supply unit 5 that requires component replenishment and to start supplying the component in a short time by inputting information to the electronic component mounting apparatus 1.

  As a result, it is possible to shorten the time required for changing the parts supply unit.

  In addition, the component supply unit mounting table 21 can be used as a work table when the component supply device is off-line removed from the electronic component mounting device 1 or when the next production model is prepared.

  The component supply unit 5 mounted on the component supply unit mounting table 21 can be replenished without opening and closing the safety cover 11 of the electronic component mounting apparatus 1 even during production of the electronic component mounting apparatus 1. It becomes.

  Further, in the component supply unit 5 mounted on the component supply unit mounting table 21, when the component is replenished, it is easy to see the suction position, and it is possible to easily confirm whether the tape has been reliably set.
