An embodiment of the present invention will be described below with reference to the drawings. In FIG. 1, reference numerals 1 and 2 denote first and second conveying means, and these first and second conveying means 1 and 2 are loop-shaped conveying paths driven by a motor 1A as shown in FIG. As shown in FIG. 1, these two loop-shaped transport paths are arranged in a V shape that spreads left and right around the front side. In addition, as shown in FIG. 1, the first and second transporting means 1 and 2 are provided with holding portions 3 and 4 for electronic components at fixed intervals, respectively.
Various electronic components are supplied from a plurality of supply units 5 and 6 to 4 and hold them. Further, as shown in FIGS. 8 to 10, mounting means 7 is provided at the front center portions of the first and second conveying means 1 and 2, and the mounting means 7 is provided.
On the other hand, the holding portions 3 and 4 are arranged to advance alternately as shown in FIG. As a result, the transport distance of the first and second transport means 1 and 2 with respect to the mounting means 7 can be reduced to half. On top of that, go into the c
The maintenance of the second conveying means 1 and 2 can be performed.

Next, the supply units 5 and 6 will be described.
As shown in FIG. 4, the electronic component 9 having the lead terminal 8 is
Band-shaped holding band 1 made of resin or paper
It is held by inserting the lead terminal 8 into the insertion hole 11 of No. 0, and is sequentially drawn upward from the inside of the box 12 shown in FIG. 1 and supplied to the holding portions 3 and 4. . A through hole 10A is intermittently provided in the center line portion of the holding band 10, and the through hole 10A is utilized to pull it upward as described below.

As shown in FIG. 5, the holding band 10 is first heated by the heater 13 used as a heating means, and when the cylinder 14 of the lifting mechanism is lifted up, the pin integrated with the cylinder 14 is raised. Reference numeral 15 is an insertion hole 1 of the holding band 10.
Since it is inserted in 1, the holding band 10 also goes up,
Further, one end of an L-shaped lever 16 is lifted by the upper end of the cylinder 14, and the other end of the lever 16 moves downward in an arc shape. The other end of this lever 16 projects into the hole of the U-shaped pressing lever 17 above it, and the other end of this lever 16 rotates while moving leftward in FIG. Also move to the left. The lead terminal 8 of the electronic component 9 held by the holding band 10 due to the movement of the pressing lever 17 to the left causes the holding portion 3 that is temporarily stopped and waiting to move to the holding portion 3 shown in FIG.
It is pushed in as shown in (a) and (b). The holding portion 3 (or 4) is a U-shaped holding chuck 18 as shown in FIG.
3 are provided on the upper and lower sides, projections 18a for preventing removal are formed on the inner surface of the lower end opening of each, and a notch 18b is formed on the advancing direction side of the holding portion 3.

The lead terminal 8 of the electronic component 9 is thus formed.
When is held by the holding chuck 18 of the holding unit, the first conveying means 1 (or the second conveying means 2) is restarted. Then, the holding band 10 is heated by the heater 13 and the adhesive force of the lead terminals 8 is reduced by the heating, so that the restart of the first transporting means 1 causes the electronic parts as shown in FIGS. 6C and 7. The lead terminal 9 of 9 is pulled out from the insertion hole 11 of the holding band 10 and is carried by the first carrying means 1.

The holding band 10 from which the electronic component 9 has been removed can be reused. Further, in this way, the holding portion 3 (or 4)
The lead terminal 8 of the electronic component 9 held by is corrected before the mounting head 19 of the mounting means 7, and the mounting head 1
The holding by 9 is ensured. That is, the mounting head 19 receives the electronic components 9 alternately sent by the first and second conveying means 1 and 2 as shown in FIG. FIG. 10 shows the positional relationship between the mounting head 19 and the delivery part. The mounting head 19 that has received the electronic component 9 at its lead terminal 8 first moves to the center, then moves downward, and then with the pusher 20. The lead terminal 8 is pressed into the hole of the substrate (not shown) provided on the XY table 21, and then the electronic component 9 is taken to the delivery section in the reverse order. Do it continuously. Reference numeral 22 in FIG. 9 is an anvil mechanism for cutting an extra lead terminal 8 projecting downward from the substrate and bending the upper part inward. Although the opening / closing mechanism of the mounting head 19 is not shown, it is based on a known air check method.

When the insertion error is further made, in FIG. 1, for example, when the electronic component 9 having the insertion error is supplied from the frontmost box 12, the first conveying means 1 is inverted. , Bring it to the delivery department. See also FIG.
The notch 18b is provided in the holding chuck 18 of the mounting head 19 as shown in FIG.
This is to avoid hitting. Further mounting head 1
Since 9 and the anvil mechanism 22 rotate 360 ° shown by arrow B in FIG. 9, the electronic component 9 can be inserted into the hole of the substrate in the entire circumferential direction.

FIG. 2 mainly shows the electrical connection state. 2A is a motor of the second conveying means 2 and 21A is XY.
The motors and 23 of the table 21 are main control devices, and controllers 24 and 25 for the first and second conveying means 1 and 2
Are connected and controlled.

The arrow A in each figure indicates the direction of rotation.
