Description

[Detailed Description of the Invention] Industrial Field of Application ＼ Invention (Relates to an electronic component supply device for automatically mounting chip-type electronic components. ゛Conventional structure and problems thereof Conventional electronic component supply As shown in FIG. 1, the device includes a ratchet wheel 1-3 that feeds out a tape 2 containing a chip-type electronic component 1 at a constant pitch, a pulley 4 that rotates in one direction, and a motor (not shown). 11116, which is supported by the first fixed support base 5 and rotates in one direction around the horizontal axis using a driving source; and a second fixed support base 7, which comes into contact with the shaft 6, and is rotatable around the horizontal axis. supported by
Friction plate example pulley 9 that winds up the cover tape 8 of tape 2
and a tape holder 10 to prevent the tape 2 from lifting up.The chip type electronic component 1 is attracted by a nozzle (A) and mounted on a printed circuit board (C) on an XY table (B). Ta.

However, in such a configuration, for example, when two or more electronic component supply devices are used, the winding drive of the cover tape 8 and the feeding drive of the tape 2 are separate, ``wound motions'', and multiple electronic component supply devices are used. Since the winding shaft 6 of the cover tape 8 of the device is operated in the same way, the winding drive shaft 6 always rotates while contacting a plurality of friction plate pulleys 9 to supply the electronic component 1. In other electronic component supply devices that do not use this method, the shaft 6 and the friction plate pulley 9 slip, necessitating unnecessary power and causing frequent wear.

OBJECTS OF THE INVENTION The present invention solves the above-mentioned conventional drawbacks, and provides an electronic component feeding device that can stably pitch-feed taped electronic components and wind up a cover tape using a single drive source. It is something to do.

Structure of the Invention The present invention comprises a pulley that rotates in one direction and is integrated with a ratchet that feeds out a tape containing a chip-type electronic component by a certain pitch, and a first pulley with a friction plate that is rotatably supported around a horizontal axis. a second friction plate pulley which is rotatably supported by a swingably supported plate for winding up the cover tape of the tape and is in contact with the first friction plate pulley; and a ratchet. One direction rotation is the first
The feed lever of the ratchet is composed of a timing belt that transmits the transmission to a pulley with a friction plate, and a seven-piece to prevent the protrusion of the chip power recovery P component that slides on the tape in the tape feeding direction via a link mechanism. Therefore, there is an effect that the chinog type parts can be automatically supplied stably by the same drive.

DESCRIPTION OF EMBODIMENTS Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
I will clarify.

In FIG. 2, reference numeral 11 denotes a pulley 14 that rotates in one direction integrally with a ratchet 13 that feeds out the tape 12 at a constant pitch.
16 is a first pulley with a friction plate that can rotate in the same direction as the rotation of the pulley 11 via a timing belt 15, and 16 is brought into contact with the first pulley 14 with a friction plate by a first spring 17 and rotated by the frictional force. The second pulley with a friction plate that winds up the cover tape 18, and the second pulley with a friction plate 16, is supported by a plate 2o that is swingable in the direction of arrow A with the first pin 19 as a fulcrum.

・ In FIG. 3, 21 is a screwdriver that prevents the electronic component 26 from protruding.
It is possible to slide in the same direction as the feeding of the tape 12 via the . 26 is a second spring 2 to prevent the tape 12 from floating up.
7 is the tape presser that presses the tape downward. Further, the tape presser 6 is fixed when lifted upward by a ball plunger 28 so that the tape 12 can be easily attached and detached.

In FIG. 4, the lid 29 is attached to the lid 29 for easy attachment and detachment of the pulley 16 with the second friction plate 16 and the cover tape 18.
It is fixed at

The operation of the electronic component supply apparatus configured as described above will be described below.

In FIG. 2, by pushing down the ratchet feed lever 22 in the direction of arrow B, the ratchet 13 rotates in the direction of arrow C, and the tape 12 is fed by a fixed pitch in the direction of the arrow. At the same time, the first pulley with friction plate 14 rotates in the direction of arrow E via the timing belt 15.

Further, the second friction plate pulley 16 in contact with the first friction plate pulley 14 rotates in the direction of arrow F and winds up the cover tape 18.

The winding amount per pitch of the cover tape 18 is set to be greater than the feed amount per pitch of the tape 12, and the difference is between the first pulley with friction plate 14 and the second pulley with friction plate 1.
It is possible to wind up a certain amount by adjusting the sliding with 6.

In FIG. 3, when the ratchet feed lever 22 is pushed down in the direction of the arrow EpG, the lever 24 swings in the direction of the arrow H via the second pinot 23 provided on the ratchet feed lever 22, and moves over the tape 12 in the direction of the arrow H. Tape 12 in direction I
As the ratchet feed lever 22 is returned, the blade 21 slides to prevent the electronic component 25 from protruding, and simultaneously with the return of the ratchet feed lever 22, the blade 21 returns to its original position, allowing the electronic component 25 to be sucked by the nozzle 26.

As described above, according to this embodiment, as shown in FIGS. 2 and 3, there is a second friction pulley 16 that winds a certain amount of the cover tape 18, and a ratchet 1 that feeds the tape 12 by a certain width.
3 and 7 blades 21 are provided to prevent the electronic components 25 from protruding, and by driving each of the 3 drives simultaneously, the power for winding the cover tape 18 can be reduced and the electronic components 25
protrusion can be prevented.

Furthermore, by fixing the tape holder with a ball plunger and fixing the lid of the second pulley with a friction plate with a magnet for one-touch removal, the tape and cover tape can be easily attached and detached.

Effects of the Invention As described above, the present invention provides a first friction mechanism that is rotatable via a timing belt and a pulley that is supported by a plate that is swingable in the tape feeding direction and is integrated with a ratchet that feeds the tape at a constant pitch. A second pulley with a friction plate is provided that comes into contact with the boot with a plate and winds up a certain amount of cover tape, and the pulley is further driven by a lever using a link mechanism to slide on the tape to prevent electronic components from protruding. Since it is equipped with a shutter, there is no need for dedicated power for winding up the cover tape, and wear and deterioration of the friction plates can be reduced even when many electronic component supply devices are used in series.
