Description

The present invention relates to an accessory reel cover that is attached to a supply reel on which a carrier tape carrying electronic components is wound.

There is a chip mounter that mounts electronic components on a substrate. Some chip mounters are equipped with a carrier tape that contains electronic components, and mount the electronic components supplied from the carrier tape on a substrate. The carrier tape is wound on a reel and attached to the chip mounter, but it is necessary to supply a new carrier tape before the electronic components on the carrier tape run out and the production line stops. In Patent Document 1, a part of the carrier tape is unwound from the supply reel, and the beginning end of the unwound carrier tape is inserted into a splicing device to perform splicing. At this time, the carrier tape may be unwound from the supply reel more than necessary. In particular, if the supply reel is unused and the carrier tape is wound up to the outer periphery of the reel, when the tape or the like that holds the tip of the carrier tape is removed, there is a problem that the carrier tape spreads outside the reel and unwinds more than necessary (Patent Document 1).

As shown in Figures 1 and 2, the reel cover 1 is composed of a disk portion 100 and a disk portion 200. A recess 120 having a bottom surface 130 is provided at the center of the disk portion 100. A protrusion 220 having a cylinder 230 is provided at the center of the disk portion 200. The reel cover 1 is attached so as to sandwich the reels 300, 310 around which a carrier tape carrying electronic components is wound. The recess 120 of the disk portion 100 and the protrusion 220 of the disk portion 200 are passed through a hole 320 provided at the center of the reels 300, 310, and the protrusion 220 is fitted into the recess 120, thereby attaching the disk portion 100 and the disk portion 200 to the reels 300, 310. In this embodiment, the diameter of the disk parts 100, 200 is configured to be approximately 2 cm longer than the diameter of the reels 300, 310, but it is sufficient that the diameter of the disk parts 100, 200 is configured to be longer than the diameter of the reels 300, 310.

Figure 3 is a front view of the disc part 100. As shown in Figure 3, the disc part 100 has a circumferential groove 110 provided on the circumference and radial grooves 140 extending radially in four directions from the center.

In this manner, the use of the reel cover 1 as an accessory attached to a reel around which a carrier tape carrying electronic components according to this embodiment is wound provides the following effects.
(a) Since the diameter of the reel cover 1 is longer than the diameter of the supply reel, there is enough room to wind the carrier tape when splicing the carrier tape, making it possible to prevent more of the carrier tape from being unwound from the supply reel than necessary.
(i) Because the reel cover 1 is made of transparent resin, it is possible to read the printing, one-dimensional code, and two-dimensional code on the supply reel with the reel cover 1 attached.
(c) The reel cover 1 has a plurality of radially extending grooves, which makes it possible to increase its strength.
(e) The reel cover 1 is configured to house the supply reel inside the circumferential groove, so that even with the reel cover 1 attached, the thickness is almost the same as that of the supply reel.

The present invention is not limited to the above-described embodiments, and various modifications are possible. Furthermore, since each of the above-described embodiments is a preferred example of the present invention, various technically preferable limitations are applied, but the scope of the present invention is not unduly limited by the above explanation.
