The table member 63 is raised to a predetermined height (this height is the same as the above-described predetermined height at which the electronic component 4 can be adsorbed by the mounting head 16) (FIG. 13A). Arrow C5) shown in the inside. As a result, the paste Pst can be supplied to the electronic component 4 by the mounting head 16 (paste supply process).

  When the control device 80 raises the table member 63 to a position of a predetermined height, it moves the mounting head 16 upward (on the paste plate 53) of the paste plate mounting pallet 52 on the table member 63 ( The arrow F2 shown in FIG. 13A, the suction nozzle 16a of the mounting head 16 is lowered (arrow E2 shown in FIG. 13A), and the paste in the paste tray 53 is placed on the electronic component 4 picked up in the pickup process. Pst is attached (FIG. 13A). The position at which the mounting head 16 attaches the paste Pst in the paste tray 53 to the electronic component 4 is substantially the same position as the position at which the mounting head 16 picks up (sucks) the electronic component 4 from the tray 43.

  When the paste Pst is attached to the electronic component 4, the control device 80 lowers the table member 63 (arrow C <b> 6 shown in FIG. 13B) and places the paste plate mounting pallet 52 placed on the table member 63. However, the table member 63 is positioned at the height stored in the paste dish storage magazine 32 (FIG. 13B). Then, the locking rod 72 is moved to the rear of the main body 71 (arrow D5 shown in FIG. 14A), and the paste tray mounting pallet 52 on the table member 63 is stored in the paste tray storage magazine 32 ( 14 (a) → 14 (b) → FIG.15 (a) → FIG.15 (b) → FIG.16 (a) Arrow D6 shown in FIG.15 (a) and arrow shown in FIG.16 (a) D7). During this time, the control device 80 moves the mounting head 16 so that the electronic component 4 to which the paste Pst is attached is positioned above the substrate 2 positioned by the substrate transport conveyor 13 (FIG. 14A). The arrow F3 shown inside), the suction nozzle 16a is lowered (arrow E3 shown in FIG. 15A), and the electronic component 4 is mounted on the substrate 2 (electronic component mounting step).

  Here, when the control device 80 returns the paste dish mounting pallet 52 placed on the table member 63 into the paste dish storage magazine 32, the squeegee 55 is lowered so that the lower edge of the squeegee 55 is the upper surface of the paste dish 53. (Arrow B3 shown in FIG. 14B), the paste Pst is scraped and leveled by the squeegee 55 by the relative movement of the paste pan 53 with respect to the squeegee 55. Then, before the paste dish 53 is completely accommodated in the paste dish accommodating magazine 32, the squeegee 55 is raised (FIG. 15B, arrow B4 shown in the figure), and the paste dish 53 is within the paste dish accommodating magazine 32. In this state, the paste Pst scraped by the squeegee 55 is positioned behind the squeegee 55 (FIG. 16A). Thereby, when the paste tray mounting pallet 52 is pulled out next, a paste film can be formed on the paste tray 53 by relative movement with the squeegee 55. When a state in which the amount of the paste Pst located behind the squeegee 55 is insufficient is detected by a detection unit (not shown), the control device 80 supplies the paste Pst from the paste supply syringe 56 into the paste dish 53. Thus, the shortage of the paste Pst is compensated.

  When the paste tray mounting pallet 52 is returned to the paste tray storage magazine 32 in this way, the control device 80 raises and lowers the table member 63 so as to newly supply the electronic component 4 (FIG. 16B). The arrow C7 shown in the figure is positioned at the height position of the tray mounting pallet 42 on which the tray 43 in which the electronic component 4 to be supplied is stored in the tray storing magazine 31 is mounted (FIG. 16 ( b)). During this time, the control device 80 moves the mounting head 16 above the table member 63 (arrow F4 shown in FIG. 16B).

A tray stored in the tray storage magazine 31 is provided. The paste tray mounting pallet 52 accommodated in the mounting pallet 42 or the paste dish accommodating magazine 32 is Since these are selectively pulled out and positioned at respective predetermined heights, the position where the mounting head 16 picks up the electronic component 4 and the position where the paste Pst adheres to the picked-up electronic component 4 are almost the same. Can be in the same position. For this reason, in the mounting operation of the electronic component 4 to be mounted on the substrate 2 by attaching the paste Pst to the electronic component 4 picked up from the tray 43, time loss can be reduced and the decrease in substrate productivity can be suppressed. it can. Moreover, since it is not necessary to provide a separate installation space for the paste supply device, the electronic component mounting machine can be easily slimmed.
