Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is formed by inserting and sealing electronic components such as a chip type capacitor chip inductor, a chip type volume and an IC chip at equal intervals, and supplying the electronic components to an automatic assembly line for electronic products. The present invention relates to a reel for winding and packing a carrier tape for carrying out.

[0002]

2. Description of the Related Art As shown in FIGS. 10 and 11, various electronic components supplied to an electronic product assembly line are stored in a carrier tape (8) by type and wound on a take-up reel (1). It is packed.

The carrier tape (8) is mainly made of synthetic resin tape (81) in which recessed pockets (9) are formed in a dense pitch.
After storing the electronic components (11) in the pocket (9),
It is composed of a cover tape (82) for sealing (9). The bottom side of each pocket is gradually narrowed.

The take-up reel (1) has large diameter flanges (21) and (21) on both sides of the winding core (2). The winding core (2) has slit grooves (3) for locking the carrier tape. ) Are provided at a plurality of locations at equal intervals.

The tip of the carrier tape (8) is bent and inserted into a desired slit groove (3), the tip of the carrier tape is locked to the winding core (2), and the carrier tape is wound on the reel (1). I am wearing.

The carrier tape winding reel (1) is set on the automatic assembly line, and the tape is pulled out to each pocket.
The electronic component (11) of (9) is supplied. When the trailing end of the carrier tape naturally comes off the slit groove (3), the detector detects this end and replaces it with the next reel.

[0007]

In the vicinity of the bent portion at the tip of the carrier tape (8), the pocket (9) is deformed or crushed, and the terminal of the stored electronic component (11) is bent or assembled. Sometimes it has the drawback of making it difficult to remove electronic components from the pocket. For this reason, it is necessary to form an empty pocket in the vicinity of the bent end portion of the carrier tape (8) in which electronic parts are not housed.

Particularly, a carrier tape having a large pocket depth has a large crushing allowance for insertion into the slit groove (3). Therefore, the number of empty pockets must be increased, and the leading end side of the carrier tape is effective. Cannot be used for. Further, since the strength of the bent portion is weakened, there is a problem that the bent portion is easily removed.

In Japanese Utility Model Publication No. 62-186866 and Japanese Utility Model Publication No. 64-3760, a step corresponding to the pocket depth of the carrier tape is provided before and after the slit groove provided in the winding core. Although there is a disclosure to prevent the pocket from being deformed by the carrier tape locking portion when the carrier tape is wound in layers, even in this case, in order to lock the leading end portion of the carrier tape to the core, the end portion of the carrier tape is It must be crushed and an empty pocket must be provided.

An adhesive tape may be used as a means for locking the carrier tape (8) on the winding core (2). In this case, since the winding tip of the carrier tape does not come off from the reel tape naturally as described above, a leader tape having a length equal to or larger than the radius of the reel is connected to the tip of the carrier tape, and the leader tape is attached. Core with adhesive tape
When it is attached to (2) and the leader tape is pulled out to the outside of the flange (21) of the reel, the detector detects the leader tape,
That is, it is detected that the carrier tape is full. In the above case, it is necessary to connect the leader tape to the carrier tape and adhere the leader tape to the reel core (2) with an adhesive tape, which is troublesome.

According to the present invention, it is possible to wind the carrier tape without crushing the tip end portion of the carrier tape, that is, without providing an empty pocket and by locking the carrier tape on the core without the need for the leader tape. This is to clarify a reel for winding a carrier tape.

[0012]

The reel of the present invention is a reel for winding a carrier tape (8) containing small electronic components in pockets (9) formed at equal pitches, and having reels at both ends of a core (2). On the winding core (2), a claw portion (52) having a flange (21) (21) and fitted in a gap (10) between pockets of the carrier tape (8) to lock the carrier tape (8) is provided. Is forming.

[0013]

[Operation and effect] Carrier tape (8) on the peripheral surface of the winding core (2)
Since the claws (52) that fit into the gaps (10) between the pockets are formed, the carrier tapes can be engaged with the claws (52) without bending the tip of the carrier tape (8). .. Therefore, unlike the conventional case, it is not necessary to provide an empty pocket for crushing the pocket (9) by bending the tip of the carrier tape, and the carrier tape can be used over the entire length without waste. The bending strength of the carrier tape (8) does not lower the tensile strength.

Further, unlike the case where the carrier tape (8) is locked to the reel by the adhesive tape, the leader tape is not required and the leader tape and the adhesive tape are not joined.
