DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improved carrier tape having a large number of storage recesses for storing electronic components and the like.

[0002]

2. Description of the Related Art Conventionally, electronic parts and the like are very fine parts, and such parts can be individually stored without being damaged, transported, and used in a mounting apparatus for assembling electronic products and the like. For the sake of simplicity, the electronic components and the like are housed in a carrier tape in which storage recesses capable of accommodating a large number of electronic components and the like are arranged, and as shown in FIG. Electronic components 54,
Storage recesses 52, 52,
52 are formed in a plurality of rows.
In a state in which the electronic components 54 are housed, respectively, a release sheet 53 is adhered to the front surface side to prevent the electronic components 54 from dropping out of the housing recess 52, and such a carrier tape 51 is mounted on the mounting device. When the electronic component 54 is taken out from each of the storage recesses 52, the release sheet 5
3 is to be peeled off as a pre-process. Thus, in the conventional carrier tape 51, a step of attaching a peeling sheet 53 is required in manufacturing, and the peeling sheet 53 is used in use in a mounting apparatus. There is a problem in that a device for peeling off is required, which increases costs in manufacturing and use. Further, when the carrier sheet 51 is turned upside down and sent by the mounting apparatus, the release sheet 53 is peeled off, and the storage recess 52 is formed.
The electronic component 54 falls down from the device, and it is practically difficult to load the carrier tape 51 in the mounting device with the carrier tape 51 turned upside down.

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view of a carrier tape, and FIG.
FIG. 3 is an enlarged view of a main part thereof, and FIG. 3 is an enlarged sectional view showing a state in which electronic components are stored. As shown in the figure, the carrier tape 1 is formed of an embossed tape made of resin, and a large number of storage recesses 2, 2, 2 are embossed at predetermined intervals along a longitudinal direction by pressing or the like. Electronic components and the like can be accommodated in 2, 2 and 2, respectively. Each accommodating recess 2 is formed in a bottomed shape having an opening on the surface 1a side. The pair of falling-off preventing pieces 3 and 3 are formed so as to face each other.
Are formed integrally when embossing each of the storage recesses 2, and the drop-off preventing pieces 3 and 3 and the storage recess 2 are simultaneously formed in one step by a press or the like. Further, in the side edge portion of the carrier tape 1, feed holes 5, 5, and 5 are formed at predetermined intervals along the longitudinal direction.

The bottom of the side walls 2a, 2a facing each other in the longitudinal direction of each storage recess 2 rises vertically, but the inclined surfaces 2b, 2b are inclined on the surface 1a side of the side walls 2a, 2a, respectively. The inclined surface 2b is formed as an inclined surface that expands from the bottom side to the surface 1a side, and is cut and raised at the center in the width direction of the inclined surfaces 2b, 2b. An opening K is formed, and a vertical elastic piece 3a is formed inside the opening K so as to be vertically raised continuously with the side wall surface 2a.
Has an elastic force applied to the opening K side by receiving a pressing force from the inside,
At the upper end of the vertical elastic piece portion 3a, a bulging portion 3c bulging inward to the inside of the storage recess 2 is integrally formed, and the upper end of the bulging portion 3c extends horizontally toward the opening K in the horizontal direction. The horizontal piece 3b is arranged at a position lower than the front surface 1a of the carrier tape 1 so as to be movable to the back side of the front surface 1a.

Accordingly, as shown in FIG. 2, the side walls 2a facing each other in the longitudinal direction of the storage recess 2 are provided with the vertical elastic piece 3a, the bulging portion 3c, and the horizontal piece 3b to prevent falling off. As shown in FIG. 3, when the electronic component 54 is to be stored in the storage recess 2 from the front surface 1a side, the electronic component 54 is formed with the bulging portions 3c, 3c as shown in FIG.
When it is moved further downward, the drop-off preventing pieces 3 and 3 spread outward, and the electronic component 54 can be easily stored in the storage recess 2. Each of the bulging pieces 3c, 3c returns to and comes into contact with the surface side of the, so that it is possible to prevent the electronic component 54 from dropping out of the storage recess 2 in a satisfactory manner.

When taking out the stored electronic component 54, a clamp claw of a mounting device (not shown) is inserted into the storage recess 2 from the front surface 1 a side of the carrier tape 1.
When the electronic component 54 is grasped by the clamp claws and lifted upward, the falling-off preventing pieces 3 and 3 spread outward, and the electronic component 54 can be easily taken out from the storage recess 2, which is extremely good for use in a mounting device. And it becomes easy to automate the mounting apparatus.

The carrier tape 1 is loaded into a mounting device in a factory or the like, and sprockets or the like are used to feed the sprockets 5, 5, 5, and 5.
The carrier tape 1 is sequentially fed in the longitudinal direction by a mounting device by rotation of a sprocket or the like, and the electronic components housed in the housing recesses 2 are sequentially taken out by the take-out devices. Further, in such a carrier tape 1, as shown in FIG. 1, it is possible to send the storage concave portion with the surface 1a side facing upward, or to send the storage concave portion with the surface 1a facing downward. A plurality of carrier tapes 1 can be set and sent at the same time by the mounting device, and the efficiency of the mounting device can be increased as compared with the conventional case.

In the present embodiment, a pair of the fall-preventing pieces 3, 3 is illustrated. However, the present invention is not limited to the two fall-preventing pieces 3, 3, but may be formed in the width direction and the longitudinal direction, respectively.
3 may be formed. Depending on the parts stored in the storage recess 2, the carrier tape 1 is immersed in an organic solvent or water while being stored in the storage recess 2, and is stored in the carrier tape 1. Can be washed.

As described above, in the carrier tape of the present invention, since there is no need to attach a release sheet to the front surface side as in the conventional case, the cost for attaching the release sheet can be reduced and the carrier tape can be formed inexpensively. In addition, an apparatus for peeling off the release sheet is not required in the mounting apparatus, and a step for peeling off the release sheet is not required, so that the cost for use in the mounting apparatus can be reduced.
