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 stored in a carrier tape in which storage recesses capable of storing 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.

[0003]

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned conventional problems, and has a reduced manufacturing cost.
Another object of the present invention is to provide a carrier tape which can simplify a mounting device at the time of use and which can be sent downward. Carrier tape formed of a resin embossed tape in which opened storage recesses are arranged at predetermined intervals, and in each of the storage recesses, a falling-off preventing piece for preventing a stored electronic component or the like from falling off is formed to protrude inward. In the above, when the carrier tape is stacked in layers, a bottom protrusion that prevents the bottom surface of the upper-side storage recess from fitting into the lower-layer storage recess is formed to project from the bottom surface of each of the storage recesses. It is that you are. The second gist is that storage recesses whose front sides capable of storing electronic components and the like are opened are arranged at predetermined intervals, and each storage recess has a fall-off preventing piece for preventing the stored electronic components and the like from falling off. In a carrier tape formed of a resin embossed tape formed to project inward, when the carrier tape is bent into a curved shape or the like, a slit for preventing the falling-off preventing piece from being displaced is provided between the storage recesses. It is formed in.

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a perspective configuration diagram of a carrier tape, FIG. 2 is an enlarged configuration diagram of a main portion from the front side, and FIG. 3 is an enlarged perspective view of a main portion in an inverted state.

In FIG. 1, a carrier tape 1 is formed of an embossed tape made of resin, and a plurality of storage recesses S, S, S are embossed at predetermined intervals along a longitudinal direction by pressing or the like. S, S, and S can store electronic components and the like, respectively.
As shown in FIGS. 2 and 3 in an enlarged manner, each of the storage recesses S has a curved side surface formed from a top surface 1a of the carrier tape 1 so as to form a curved surface, and the bottom surface of the curved side wall surface 2 is curved. As shown in FIG. 3, a connecting bottom surface 4 is continuously formed in the width direction between the bottom curved surfaces 3, and both sides of the connecting bottom surface 4 in the longitudinal direction are formed as shown in FIG. 3. Are cutout openings K, K. The cutout openings K, K are opened to cut and raise the falling-off preventing pieces 5 to be integrally formed when the storage recess S is deeply squeezed and embossed. On the upper surface 1a side of the notch opening K, a pair of falling-off prevention pieces 5, 5 are formed to protrude inside the storage recess S so as to face each other, and each of the falling-off prevention pieces 5 is inclined downward from the upper surface 1a. An inclined piece 5a and a storage recess S substantially horizontally extending from the tip of the inclined piece 5a. The falling-off prevention piece 5 is provided with elasticity in the up-down direction, and as shown in FIG. 4, the clamp claw 10 of the mounting device is moved from above. When entering into the storage recess S, each of the falling-off preventing pieces 5 is elastically moved downward as shown by the imaginary line in FIG. 4, and the clamp claw 10 can be inserted into the storage recess S. The clamp claw 10 is configured so as to grasp the electronic component P in the storage recess S and take it out of the storage recess S. The pair of drop-off preventing pieces 5 and 5 can effectively prevent the electronic components P and the like housed in the housing recess S from falling out of the housing recess S.

Returning to FIGS. 2 and 3, the description will be continued.
Bottom projections 6, 6 projecting outward in the width direction are formed on the bottom surface at the widthwise ends of the bottom curved surfaces 3, 3 of the carrier tape 1, and these bottom projections 6, 6 are also embossed. Sometimes formed integrally. Further, in this example, a slit 8 is provided between the storage recesses S in the width direction between the storage recesses S.
The upper and lower portions are cut in a penetrating manner. In the drawing, reference numeral 7 denotes a feed hole for automatically feeding the carrier tape 1 by being inserted into a mounting device.

As shown in FIG. 5, the carrier tape 1 is wound around an outer periphery of a reel 11 in a stacked state and shipped, inserted into a mounting device, and continuously from the end as shown in FIG. In this example, since the bottom protrusions 6 and 6 are formed in the bottom surface of each of the storage recesses S in the width direction so as to protrude in the width direction, even when they are stacked as shown in FIG.
As shown in FIG. 6 (enlarged cross-sectional view taken along the line AA in FIG. 1), even if the lower-side storage recess S and the upper-layer storage recess S are aligned, as shown in FIG. The bottom protrusions 6 and 6 on the upper layer side come into contact with the upper surface 1a of the recess S, and the bottom surface of the storage recess S on the upper layer side, particularly the coupling bottom surface 4 fits into the storage recess S on the lower layer side. No bottom protrusion 6
6 is configured to prevent the fitting.

In other words, when the bottom projections 6 and 6 are not present, in a state where they are stacked as shown in FIG. When the upper connecting side is separated from the upper connecting side, the lower connecting side 4 pulls the lower layer falling-off preventing piece 5 upward, thereby forcing the lower layer falling-off preventing piece 5.
In order to reliably prevent the fall-off prevention piece 5 from being damaged, the bottom projections 6 and 6 are formed to protrude in the width direction on the bottom side of each storage recess S.

The operation of the slits 8 formed between the storage recesses S, S will be described. In a state where the slits 8 do not exist, for example, as shown in FIG. In the state where the slit 8 does not exist when the bending direction shown by the arrow B is applied, that is, when the winding is wound in a small diameter on the reel 11 or the like when used with the side facing downward, By receiving the bending force, as shown by imaginary lines in FIG.
The upper surface 1a is inclined by the bending force, so that the falling-off preventing piece 5 rises and displaces inside the storage recess S as shown by the imaginary line, and thus the falling-off preventing piece 5 is bent by the bending force. When the electronic component P is displaced in an upright manner, the gap between the pair of drop-off preventing pieces 5 and 5 becomes large. Therefore, as shown in FIG. The slit 8 is formed so that the falling-off preventing piece 5 is not displaced even when receiving such a bending force, since the slit 8 may be pulled out from the concave portion S and fall downward.

That is, as shown in FIG. 7, even when a bending force in the bending direction shown by B acts, as shown in FIG.
Bending force acts on the portion, and the bending force does not act as a force for displacing the fall-preventing pieces 5, 5 as in the prior art. Therefore, even when the bending force acts, the falling-off preventing piece 5 is the same as usual. , The removal of the electronic component P can be prevented well, and the removal of the electronic component P can be reliably prevented even when the carrier tape 1 is used with the upper surface facing downward. You can do it.

[0011]

According to the present invention, storage recesses having openings on the front side capable of storing electronic components and the like are arranged at predetermined intervals, and each storage recess has a drop-off preventing piece for preventing the stored electronic components and the like from falling off. In a carrier tape formed of a resin embossed tape formed so as to protrude inward, when the carrier tapes are superposed in layers, the bottom surface of the upper-side storage recess fits into the lower-layer storage recess. Is formed on the bottom surface of each of the storage recesses,
Even when the carrier tape is wound around a reel or the like and stacked in layers, the bottom surface of the upper-side storage recess does not fit into the lower-layer storage recess, and the fall-off prevention piece formed in the storage recess is damaged. Has the effect of being able to favorably prevent the radiation.

In addition, storage recesses having openings on the front side capable of storing electronic components and the like are arranged at predetermined intervals, and a drop-off preventing piece for preventing the stored electronic components and the like from falling out protrudes inward in each of the storage recesses. In the carrier tape formed of the formed resin embossed tape, when the carrier tape is bent in a curved shape or the like, a slit for preventing the falling-off preventing piece from being displaced is formed between the storage recesses. By doing so, even if the carrier tape receives a bending force in a curved shape or the like, the slit serves as a bending fulcrum, and the bending force does not act on the falling-off preventing piece, so the falling-off preventing piece is not displaced,
The falling-off preventing piece can effectively prevent the electronic components and the like housed in the housing recess from falling off, and has an effect that the function of the falling-off preventing piece can be favorably maintained even when a bending force is applied.
