Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a taping generally used for an automatic assembly machine such as a device for mounting a leadless type microelectronic component (hereinafter referred to as a chip component) on a circuit board. The present invention relates to a component supply device.

2. Description of the Related Art As shown in FIG. 3, a chip component mounting machine is equipped with a plurality of taping component feeders (hereinafter referred to as feeders) 1 and a moving table 2 for moving an arbitrary feeder 1 to a predetermined position. It is composed of a nozzle 4 for moving the chip component from the supply device 1 to the circuit board 3 and an XY table 5 for positioning the circuit board 3 at a predetermined position. Among them, the subordinate supply device 1 is, for example, as shown in FIG. 4, when it is pressed in a direction of an arrow A by a drive unit 6 with a constant stroke, the tape 7 is fed through a link mechanism and a ratchet feed mechanism.
Is fed at a constant pitch in the direction of arrow B to feed the parts. Since the XY table 8 is inserted below the supply device 1 in order to downsize the entire mounting machine, the tape 7 after the chip parts are supplied has a curvature fixed to the moving table 10 from the guide portion 9. The dust chute 11 is passed through and the cutter 12 guides the cutting process.

In this case, it is most stable to feed the tape 7 horizontally. Therefore, although not shown, the reel is placed at the rear of the cassette and below the tape running surface.

DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention However, in the above-described configuration, when the supply device 1 is detached from the moving table 2, the supply device 1 has to be pulled out upward, so that the guide portion 9 and the dust chute 11 come into contact with each other. It becomes very difficult for the tape 7 to receive and remove the force in the shearing direction. Further, it is often the case that the cutter unit 12 is not synchronized because it is an expensive and complicated mechanism to synchronize with the tape feeding of the feeder 1. Therefore, there is a possibility that the tape 7 rides on the upper surface of the cutter blade and the bite feeding of the tape 7 is not reliably performed. Further, the tape width is diversified to 8 mm, 12 mm, 24 mm, and 32 mm due to the size of the chip parts. However, in the conventional feeder 1, since the dust chute 8 having different widths is fixed to the moving table 10, the feeder is 1 had to be installed in a specific position to supply the parts.

The present invention solves the above problems, and facilitates attachment / detachment to / from a moving table, can be installed at an arbitrary position on the moving table, and can reliably perform tape pitch feeding. It is intended to provide.

Means for Solving the Problems In order to solve the above-mentioned problems, in the tape-feeding device of the present invention, the tape after the components are supplied is set in the tape feeding direction to the parts feeding position below the parts feeding position. A guide portion that guides horizontally in a reverse direction by a predetermined distance and then guides vertically downward through a curvature portion provided at one end of the guide portion, and an opening portion in the up-and-down direction that is in contact with the guide portion. And a dust chute for guiding the tape, which has been guided through the parts, after the parts are supplied in the vertical direction to the cutter part provided below, and the bending amount of the tape feeding pitch or more can be allowed only in the curved part of the guide part. An escape portion is provided, and the dust chute is configured to be attachable to and detachable from the moving table independently of the guide portion.

With the above-described structure, the taping component feeding device of the present invention is provided with the curved portion having the escape portion capable of allowing the amount of deflection equal to or larger than the feeding pitch of the tape to be provided in the guide portion, so that the tape pitch feeding can be reliably performed. It will be possible. Further, since the guide portion and the dust chute are in contact with each other in the vertical direction and the dust chute is detachably provided on the moving table according to the width of the tape, the taping component feeder can be easily attached to and detached from the moving table. It can be installed at any position on the moving table.

Examples Hereinafter, a taping component supply apparatus according to an embodiment of the present invention will be described with reference to the drawings. FIG. 1 shows a taping component supply device according to an embodiment of the present invention. In FIG. 1, when the drive unit 6 pushes the variable pitch lever 14 with a constant stroke in the direction of arrow A, the rotation of the pitch variable lever 14 is transmitted to a ratchet wheel 18 having a feed claw 17 via a lever 15 and a plate 16, and the tape 7 are sent at a constant pitch in the direction of arrow B. After the parts are supplied, the tape 7 has a relief portion 9'that allows a deflection amount equal to or larger than the feeding pitch of the tape 7.
From the guide portion 9 having the curved portion having the dust chute
It is guided to the cutter unit 12 through 11 and cut. The guide 9 and the dust chute 11 are in linear contact with each other in the vertical direction as shown in FIG. 1, and the dust chute 11 is detachably attached to the moving table 10 by a hook 11 '. Further, the dust chute 11 is provided with several widths according to the width of each tape.

As described above, according to the taping component feeding apparatus of the present embodiment, the tape pitch feed can be reliably performed by providing the guide portion with the curved portion having the escape portion capable of allowing the amount of deflection greater than the tape feed pitch. You can Further, since the guide portion and the dust chute abut in the vertical direction and the dust chute is detachably provided on the moving table according to the width of the tape, the taping component feeder can be easily attached to and detached from the moving table. It can be installed at any position on the moving table and can easily handle tapes with different widths.

EFFECTS OF THE INVENTION As is apparent from the above description of the embodiments, according to the taping component supply device of the present invention, the guide portion is provided with the curved portion having the escape portion capable of allowing the deflection amount equal to or larger than the feeding pitch of the tape. The tape pitch can be reliably fed. Further, since the guide portion and the dust chute are in contact with each other in the vertical direction and the dust chute is detachably provided on the moving table according to the width of the tape, the taping component feeder can be easily attached to and detached from the moving table. It can be installed at any position on the moving table and can easily handle tapes with different widths.
