DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tape feeder,
More specifically, the present invention relates to a tape feeder that can smoothly feed a tape pitch even when an electronic component stands up in a tape pocket due to a pickup error.

[0002]

2. Description of the Related Art Resistor chips, capacitor chips, ICs,
2. Description of the Related Art In an electronic component mounting apparatus that automatically mounts an electronic component such as an LSI on a substrate, a tape feeder is frequently used as a supply form of the electronic component.

FIG. 3 is a sectional view of a main part of a conventional tape feeder, where 101 is a guide member, and 102 is a guide member 1.
01 is a sprocket as a pitch feed means provided in the front part of No. 01. The tape 103 led out from a supply reel (not shown) travels along the upper surface of the guide member 101 while being pitch-fed by the sprocket 102, and at the pickup position Q, the electronic component stored in the pocket 104 of the tape 103 P is adsorbed and picked up by the nozzle 105 of the transfer head, and is transferred and mounted on the substrate.

In this case, since the electronic component P jumps out of the pocket 104 and a pickup error occurs, a shutter 106 is provided in front of the pickup position Q. Further, a cover plate 107 is provided on the upper portion of the sprocket 102 to prevent the tape 103 from floating off the sprocket 102 and coming off.

[0005]

However, the electronic component P
Electronic component P is in pocket 1
There is a case where the user stands in the pocket 104 and stands in the pocket 104. In such a state, the tape 10
3 is pitch-fed, the electronic component P
Between the cover plate 107 and the tape 103
There was a problem that the sending of paper was hindered.

Accordingly, an object of the present invention is to provide a tape feeder which has solved the problems of the conventional means.

[0007]

For this purpose, the present invention provides a guide member for guiding a tape in which electronic components are stored in a pocket, a tape supply reel provided at a rear portion of the guide member, and a guide member. A pitch feeding means provided at a front portion of the member and feeding the tape at a pitch along an upper surface of the guide member; In a tape feeder provided with a cover plate for preventing lifting of the tape, a tunnel portion is provided on the cover plate for passing an electronic component raised in a pocket of the tape due to a pick-up error of a transfer head.

[0008]

According to the above construction, even if the electronic component rises in the tape pocket due to the pick-up error of the transfer head, the electronic component passes through the tunnel without being caught between the pocket and the cover plate. The electronic component can be supplied to the transfer head while smoothly feeding the tape at a pitch without hindering the feeding of the tape.

[0009]

Next, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a perspective view of a tape feeder. 1
Is a long plate-shaped guide member, a supply reel 3 of the tape 2 is provided at a rear portion thereof, and a sprocket 4 as a pitch feed means of the tape 2 is provided at a front portion thereof. When the sprocket 4 rotates by a pitch, the tape 2 is guided on the upper surface of the guide member 1 and the transfer head 5 is moved.
The pitch is fed toward the pickup position Q by the 0 nozzle 51.

Reference numeral 5 denotes a peeling claw of the cover tape 2a provided on the upper surface of the substantially central portion of the guide member 1. The peeling claw 5 is pressed against the upper surface of the tape 2, and the cover tape 2 a stuck on the upper surface of the tape 2 is peeled off by the leading edge 5 a, and is wound on the take-up reel 10.

1 and 2, reference numeral 20 denotes a shutter provided behind the pickup position Q. The shutter 20 reciprocates in the feed direction of the tape 2 by means not shown to open and close the pickup position Q. The electronic component P is prevented from jumping out of the pocket 26. Reference numeral 21 denotes a frame mounted on the front end of the guide member 1, and one end of a cover plate 22
Is rotatably mounted on the shaft. The cover plate 22 is urged downward by a spring (not shown) to
Is prevented from rising off the sprocket 4 and coming off.

Reference numeral 23 denotes a tunnel formed on the cover plate 22, and is provided along a pitch feed path of the electronic component P. Even if the electronic component P rises in the pocket 2b of the tape 2 due to a pick-up mistake of the transfer head 50 or the like, the electronic component P is not sandwiched between the pocket 2b and the cover plate 22 and the tunnel portion 23
, So the feed of the tape 2 is not hindered,
Pitch feed can be performed smoothly.

The present apparatus has the above-described configuration, and the operation will be described next. When the sprocket 4 rotates as shown in FIG. 1, the tape 2 is pitch-fed to the pickup position Q after the cover tape 2a is peeled off by the peeling claw 5 on the way, and in FIG. Then, the electronic component P is picked up by the nozzle 51 and then sent forward along the sprocket 4, and the tape 2 is cut and discarded by the cutter 30. Even if the electronic component P rises from the inside of the pocket 2b of the tape 2 due to a pick-up mistake of the transfer head 1 or the like, this part passes through the tunnel portion 23 without being sandwiched between the pocket 2b and the cover plate 22. After turning around the sprocket 4, it is cut by the cutter 30. As described above, according to this means, even if the transfer head 50 misses the pick-up of the electronic component P, the electronic component P can be supplied to the transfer head 1 while smoothly feeding the tape 2 at the pitch.

[0015]

As described above, the present invention provides a guide member for guiding a tape in which electronic components are stored in a pocket, a tape supply reel provided at a rear portion of the guide member, and a guide member for the guide member. A pitch feeding means provided at a front portion for feeding the tape at a pitch along the upper surface of the guide member; and a lifting of the tape which is located at an upper part of the pitch feeding means and is fed at a pitch along the pitch feeding means. In a tape feeder provided with a cover plate for preventing the transfer head, the transfer plate is provided with a tunnel portion through which electronic components that have risen in the pocket of the tape due to a pick-up error of the transfer head are provided. Even if an electronic component stands up in the pocket of the tape due to a mistake, this raised part is Without being sandwiched between the pocket and the cover plate, so go through the tunnel portion, the feed of the tape without being inhibited, can be carried out smoothly pitch feed.
