  When the transfer pallet 18 is transferred to the belt conveyor 40, the first moving member 22 is controlled by the first control unit 38 to move from the transfer position (see the solid line in FIG. 9) to the retracted position (see the broken line in FIG. 9). Moving.

  As shown in FIG. 1C and FIG. 2, the electronic component mounted on the substrate 12 supported by the support portion 20 of the conveyance pallet 18 is transferred to the substrate by being conveyed by the belt conveyor 40 in the reflow furnace 14. 12 is soldered.

  As shown in FIGS. 3A and 3B and FIG. 4, the second control unit 56 includes the second moving member 44 so that the belt conveyor 40 and the belt conveyor 42 are linearly arranged in plan view. To move. That is, the second control unit 56 moves the second moving member 44 to the transfer position (FIG. 4).

  Further, the second control unit 56 controls the rotation drive of the belt conveyor 42 provided in the second moving member 44 moved to the transfer position, and the conveyance pallet 18 conveyed by the belt conveyor 40 is transferred to the belt conveyor 42. It is made to receive (the figure on FIG. 3 (B)).

  Further, the second control unit 56 controls the lifter 50 to lower the transport pallet 18 and support the substrate 12 on the belt conveyor 52. Thereby, the conveyance pallet 18 and the board | substrate 12 isolate | separate (separate) (FIG. 3 (B) lower figure).

  Further, as shown in FIGS. 3B, 3C, and 4, the second control unit 56 controls the rotational drive of the belt conveyor 52 and transfers the substrate 12 to the belt conveyor 54.

  When the substrate 12 is transferred to the belt conveyor 54, the second moving member 44 that supports the transport pallet 18 moves from the transfer position (see the solid line in FIG. 9) to the retracted position (see the broken line in FIG. 9).

  As shown in FIG. 9, the delivery device 58 includes the first moving member 22 (the transporting pallet 18 supported by the second moving member 44 (see the broken line in FIG. 9) disposed at the retracted position. (See the broken line in FIG. 9).

[When the substrate 12 is set to be transported without using the transport pallet 18]
As shown in FIGS. 5A and 5B and FIG. 6, the first control unit 38 is placed on the transport path of the substrate 12 on which the electronic components are mounted and transported by the belt conveyor 16 in step 200 (see FIG. 9). Moves the first moving member 22 so that the belt conveyor 16 and the belt conveyor 26 are arranged linearly in plan view. That is, the 1st control part 38 moves the 1st moving member 22 to a transfer position (when the 1st moving member 22 is a figure of the center left side of FIG. 6). Since the transport pallet 18 is not used, the transport pallet 18 is not provided inside the first moving member 22.

  Further, when the width dimension of the belt conveyor 40 is equal to the width dimension of the belt conveyor 16 (dimension E shown in FIG. 1B), the first control unit 38 drives the belt conveyor 26 to rotate. And the substrate 12 transported by the belt conveyor 16 is received by the belt conveyor 26 (in the case of the first moving member 22 in the center left view of FIG. 6).

  Next, the first control unit 38 moves the first moving member 22 so that the belt conveyor 26 and the belt conveyor 40 are linearly arranged in a plan view (the first moving member 22 is located at the center right side in FIG. 6). In the case of the figure).

  Next, the 1st control part 38 controls the rotational drive of the belt conveyor 26, and delivers the board | substrate 12 to the belt conveyor 40 (when the 1st movement member 22 is a center right figure of FIG. 6).

  As shown in FIGS. 5C and 6, the electronic component mounted on the substrate 12 is soldered to the substrate 12 by being conveyed in the reflow furnace 14 by the belt conveyor 40.

  As shown in FIGS. 7A, 7B, and 8, the second control unit 56 moves the second moving member 44 so that the belt conveyor 40 and the belt conveyor 52 are linearly arranged in plan view. The first moving member 44 is moved (in the case of the diagram on the left side of the center in FIG. 8).

  Next, the second control unit 56 controls the rotational drive of the belt conveyor 52 to cause the belt conveyor 52 to receive the substrate 12 conveyed by the belt conveyor 40 (the first moving member 44 is located at the left side of the center in FIG. 8). In the case of the figure).

  Next, the second control unit 56 moves the first moving member 22 so that the belt conveyor 52 and the belt conveyor 54 are linearly arranged in plan view (the first moving member 44 is located at the center right side in FIG. 8). In the case of the figure).

  Next, the second control unit 56 controls the rotational driving of the belt conveyor 52 to deliver the substrate 12 to the belt conveyor 54 (in the case where the first moving member 44 is in the center right view of FIG. 8).

  As described above, the substrate 12 is supported (mounted) on the support portion 20 provided on the transport pallet 18 with a simple configuration in which the lifter 36 raises the transport pallet 18.

  Further, the lifter 50 lowers the transport pallet 18 so that the substrate 12 is separated from the transport pallet 18 with a simple configuration (support of the substrate 12 by the transport pallet 18 is released).

  Further, when the setting is made so that the transport pallet 18 is not used, since the substrate 12 is transported in the reflow furnace 14 without using the transport pallet 18, the step of getting the substrate 12 on and off the transport pallet 18 is eliminated. In other words, a thick substrate has higher rigidity than a thin substrate, so that the warpage of the substrate due to the heat of the reflow furnace is small, so it is necessary to use a transport pallet when transporting a thick substrate. No. Thus, in the case of a thick substrate, there is no step of getting the substrate on and off the transfer pallet 18.

  In addition, after receiving the substrate 12, the first moving member 22 and the second moving member 44 are moved so that one belt conveyor 40A is fixed and the other belt conveyor 40B is moved in the width direction so that a pair of belts is moved. Even when the width dimension of the conveyor 40 is made equal to the width dimension of the pair of belt conveyors 16, the step of getting on and off the substrate 12 on the transport pallet 18 is eliminated.

  Further, the delivery device 58 receives the transport pallet 18 that has been retracted from the transport path of the substrate 12 by the second moving member 44 from the second moving member 44 that has been moved to the retracted position, and the first moving member 22 that has moved to the retracted position. hand over. For this reason, the conveyance pallet 18 is reused (reused). The delivery device 58 can employ, for example, a general pair of belt conveyors in which an endless belt rotates using rollers or the like. In this case, the width and height of the belt conveyor are set to a width and height that can transport the transport pallet 18. When the transport pallet 18 is transferred from the second moving member 44 at the retracted position to the delivery device 58, the belt conveyor 42 and the belt conveyor of the delivery device 58 are operated. In addition, when the transfer pallet 18 is transferred from the delivery device 58 to the first moving member 22 at the retracted position, the belt conveyor 28 and the belt conveyor of the delivery device 58 are operated.

  Although the present invention has been described in detail with respect to specific embodiments, the present invention is not limited to such embodiments, and various other embodiments are possible within the scope of the present invention. It is clear to the contractor.

  For example, in the above embodiment, one belt conveyor 40A is fixed and the other belt conveyor 40B is moved in the width direction so that the width dimension of the pair of belt conveyors 40 is equal to the width dimension of the pair of belt conveyors 16 and 54. However, both the belt conveyors are moved so that the width dimension of the pair of belt conveyors 40 is equal to the width dimension of the pair of belt conveyors 16, 54, and the position in the width direction of the pair of belt conveyors 40 and the pair of belt conveyors. The positions in the width direction of 16 and 54 may correspond to each other. In this case, after the substrate 12 is received, the first moving member 22 and the second moving member 44 are not moved.

  In the above embodiment, the state shown in FIGS. 5 and 7 shows the state where the transport pallet 18 is not present. However, since the transport pallet 18 is not used, the transport pallet 18 may be present.
