Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electronic component supplying device for supplying a chip electronic component, which is used in association with an electronic component automatic mounting device for mounting a chip electronic component on a printed circuit board.

[0002]

2. Description of the Related Art Conventionally, (a), (b), (c) of FIG.
Various chip-type electronic components 15a to 15 as shown in (d)
d is stored in a plurality of storage recesses 16a formed continuously on the carrier tape 16 shown in FIG. 4 at regular intervals, and a cover tape 17 is attached to the upper surface of the storage recesses 16a for packaging.
It is supplied to the user in the form of taping in which a predetermined number of pieces is wound around.

Such a taping electronic component 15d is used by being mounted in a conventional electronic component supplying apparatus as shown in FIG. 5, and in FIG. 5, a supply reel 18 is a reel connected to a body frame 20. It is rotatably attached to the side plate 21. The carrier tape 16 pulled out from the supply reel 18 is guided to the feed roller 22 and provided in the electronic component automatic mounting device (not shown) mounted with the electronic component supply device in association with the operation thereof. The feed lever 23 (also not shown) moves the feed lever 23 of the electronic component supply device in the direction of the arrow Y ₁ in the drawing, and the link 24 attached to the feed lever 23
The ratchet 25 is rotated by a constant angle via. Then, the feed roller 22 interlocked with the ratchet 25 is moved by a fixed pitch.

Further, the carrier tape 16 is peeled off by the cover tape peeling section 26 in front of the feed roller 22 (on the side of the supply reel 18), and the peeled cover tape 17 is wound on the cover tape take-up reel 27. The carrier tape 16 from which the cover tape 17 has been peeled off is conveyed to the electronic component take-out section 28, and at the same time when the feed roller 22 conveys the carrier tape 16, the carrier tape 16 is taken out in association with the ratchet 25. From the portion 28, a vacuum suction head (not shown) sucks and takes out the chip-type electronic component 15d housed in the housing recess 16a. Thereafter, the feed lever 23 is released from the pushing force of the feed lever and returns to the original position in the same Y ₂ direction by the biasing force of the tension spring 29.

When the above series of operations are repeated, the used carrier tape 16 is discharged to the outside of the electronic component supplying device and finely cut by a cutter (not shown) which is interlocked with the operation of the electronic component automatic mounting device. It was configured to be discarded.

[0006]

However, in the conventional electronic component supplying apparatus thus constructed, not only dust is generated because the used carrier tape 16 is finely cut and discarded, but also this electronic component supplying device is used. The electronic component automatic mounting device for mounting the device requires a cutter, a driving mechanism therefor, and a carrier tape collecting mechanism (neither of which is shown), resulting in a large size and a significant cost increase.

Further, it is difficult to increase the speed of the cutter, its driving mechanism and carrier tape collecting mechanism, which has been an obstacle to speeding up of the electronic component automatic mounting apparatus.

The present invention is intended to solve such a conventional problem, and it is possible to collect used carrier tapes without cutting them and to sufficiently cope with the speedup of the automatic electronic component mounting apparatus. It is intended to provide.

[0009]

In order to solve this problem, an electronic component supply device of the present invention is provided with a guide portion for guiding and conveying a carrier tape after taking out an electronic component, and a guide portion for conveying the carrier tape. The carrier tape winding portion for winding the carrier tape is provided.

[0010]

With this structure, since the used carrier tape is wound and collected in the form of tape, the cutter of the electronic component automatic mounting apparatus, its driving mechanism and the carrier tape collecting mechanism are not required, and dust is not generated. Therefore, the cost and speed of the device can be reduced.

A tension spring 12, a connecting rod 13 that connects the feed lever 23 and the drive lever 8, and a reel side plate 2 are attached to the reel disc 6 to be engaged therewith. It is composed of a reversal preventing claw 14.

The operation of the electronic component supply apparatus of the present invention configured as described above will be described below. In FIG. 1, the carrier tape 16 after being supplied from the supply unit and supplying the chip-shaped electronic component 15d (not shown) by the same operation as in the related art is 180 ° by the feed roller 22.
The carrier tape 16 which is inverted and guided to the guide groove 5 provided in the main body frame 3 and guided along the guide groove 5 is finally wound around the recovery reel 4.

In this operation, the feed lever 23 moves in the direction of the arrow Y ₁ in the drawing to convey the carrier tape 16, and the drive lever 8 which is interlocked by the connecting rod 13 having one end connected to the feed lever 23 is moved. move to the X ₁ direction, the same is the connecting pin 10 which is coupled to the drive lever 8 a ratchet lever 9 which is rotatably mounted together with the drive lever 8 to pivot shaft 7 at the same time pushing in the same direction X _1.

The ratchet pawl 11 attached to the tip of the ratchet lever 9 pushed up by the connecting pin 10 is in the opposite direction (the same X ₁ direction) to the winding direction (the same X ₂ direction).
The reel disk 6 is rotated while sliding on the reel disk 6, stopped at the uppermost point of the ratchet lever 9, and is engaged with the reel disk 6 again.

At this time, the reel disc 6, which is engaged with the ratchet pawl 11, rotates in the winding direction by the reversal prevention pawl 14 attached to the reel side plate 2, but in a direction opposite to the winding direction. Since it is restricted from rotating, it does not rotate and remains stationary.

When the feeding of the carrier tape 16 is completed and the feed lever 23 returns in the Y ₂ direction, the connecting rod 13 moves the drive lever 8 which is interlocked with the feed lever 23 in the X ₂ direction, and this drive lever 23 moves. The tension spring 12 mounted between the ratchet lever 9 and the ratchet lever 9 extends, and the return force of the tension spring 12 causes the ratchet lever 9 to rotate in the same X ₂ direction so that the ratchet pawl 11 attached to the ratchet lever 9 is reeled. The disk 6 is rotated in the winding direction while being engaged, and the recovery reel 4 attached to the reel disk 6 winds up and collects the carrier tape 16 discharged from the feed roller 23.

In this embodiment, the carrier tape 16 is wound around the collecting reel 4 and collected, but the collecting box is connected to the main body frame 3 and guided by the guide groove 5 in the collecting box. It is also possible to store and collect the carrier tape.

[0019]

EFFECTS OF THE INVENTION The electronic component supplying apparatus of the present invention having the above-described structure has the following features. Since the drive mechanism and its drive mechanism and the carrier tape collecting mechanism are unnecessary, cost reduction and downsizing can be realized.

(2) Since the cutter of the electronic component automatic mounting device and its driving mechanism are not required, the speed of the device can be increased.
This can improve productivity.

(3) Since the carrier tape is not cut, dust-free can be achieved. (4) Since the carrier tape is collected for each reel, it can be separately collected and reused.
