Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an electronic component storage band used for storing relatively minute mass-produced components such as various electronic components and precision electronic components.

[0002]

[Prior Art]

 As the electronic component storage band, there are square hole punch carrier tapes and embossed carrier tapes standardized by JIS etc., and paper adhesive carrier tapes are also known. In all of these, a plastic tape or paper tape is integrally formed with a concave portion for accommodating electronic components, and after accommodating the electronic components in the concave portion, a long cover tape is adhered to the upper surface thereof to form a reel. It is an electronic parts storage band that can be wound around.

Such a carrier tape is provided with a concave portion that conforms to the shape and shape of an electronic component, but it is practically difficult to deal with a rolled-up electronic component of a similar shape. Met. In addition, since the plastic tape carrier tape is manufactured by press molding or vacuum molding using a mold, a mold suitable for the shape of each electronic component is used. In the manufacture of carrier tapes for different electronic parts, the molds are changed each time and the recesses are formed on the plastic tape that matches the product size. However, according to this method, the plastic tapes are classified into units, and it is extremely difficult to form combined recesses for different electronic components on one plastic tape.

Further, for example, in an electronic component package such as a quad flat package (QFP) having leads in four directions, one having a protrusion for fixing the electronic component main body on the bottom surface of the recess is Although it is used, conventional press molding or vacuum molding has a problem that it is difficult to fix the protrusions sufficiently because it is difficult to form the protrusions.

Further, in the production of a conventional carrier tape, a feed hole having a predetermined pitch is punched at one side edge of a long plastic tape in parallel with the continuous molding of the concave portion by a mold. .. This punching is usually performed in parallel with the operation of moving the plastic tape and continuously heating it to the deformation temperature of the plastic to sequentially form the recesses for storing electronic parts by vacuum molding or the like. Since the carrier tape formed in this way shrinks slightly even when it is cooled, there is a problem that the pitch deviation of the feed hole occurs in particular, and the pitch accuracy decreases, and burrs easily occur in the hole portion. There is also a problem.

[0006]

[Problems to be solved by the device]

 Therefore, an object of the present invention is to provide a practically desirable electronic component storage band which is excellent in the pitch accuracy of the feed holes and is free from burrs. Another object of the present invention is to provide an electronic component storage belt for storing several different electronic components on the same connecting tape, and in particular, having a combination of a combination of concave portions having different protrusion shapes on the bottom. ..

[0007]

[Means for Solving the Problems]

 The present inventors have conducted many trials and researches on a carrier tape that solves the above problems, and have developed a highly practical electronic component storage band. That is, according to the present invention, a long connecting tape in which feed holes for transport arranged at regular pitches in the feed direction and predetermined square holes are formed, and a tape for insertion which is inserted into the square holes, The gist of the present invention is an electronic component storage belt formed by combining an electronic component storage rectangular container (hereinafter, abbreviated as a storage container) whose upper opening peripheral edge is integrally joined to the square hole peripheral edge.

The electronic component storage band of the present invention comprises a storage container for storing a specific electronic component, and a connecting tape formed with a predetermined square hole and a tape feed hole to which the electronic component can be fitted in a fitting manner. The technical feature is that they are constructed by combining them. Further, the holes formed in the tape are punched out at room temperature, so that the pitch and shape are excellent, and the storage holes for the desired electronic components are properly combined and inserted into the storage holes (joint integration). Therefore, the electronic component storage band of the present invention can be provided as an electronic component storage band capable of storing a plurality of electronic components.

As described above, the electronic component storage band of the present invention has a long length in which a transporting feed hole and a penetrating square hole for inserting a storage container are formed at room temperature in the feed direction in advance for each connecting tape width. In the square hole of the connecting tape, a container with a recess matching the shape of the electronic component is formed by injection molding, vacuum molding, press molding, etc. to form only the storage container, and insert it into the square hole of the connecting tape. It is obtained by fitting and fitting and the peripheral edge of the opening of the storage container is integrally joined to the peripheral edge of the square hole. As the joining method, any conventionally known method such as an adhesive, heat sealing, or ultrasonic sealing can be used.

In addition, for a storage container having a recess, for example, a type in which leads of QFP or the like are projected in four directions is used in which a protrusion is formed on the bottom of the recess to fix the mold body. In order to form the ridges with high accuracy, it is preferable to use injection molding. The connecting tape can be processed by known connecting press molding. Specifically, it can be easily obtained by the continuous punching process under normal temperature conditions without heating the loop tape by using the upper and lower molds having the punch holes for punching the transport feed holes and the square holes.

It is integrated by thermocompression bonding with a machine.

[Action]

 According to the present invention, since the connecting tape and the storage container are formed in different steps, it is possible to use the connecting tape also as the storage container by changing the shape, for example, the size of the storage container. Can be manufactured, and significant improvements in terms of cost and control can be achieved. In addition, the dimensional accuracy can be greatly improved compared to the conventional product, and the formation of the storage container with the ridge at the bottom can be formed with high precision by injection molding.

【Example】

 A long polyvinyl chloride tape conductively coated with tin oxide powder having a width of 24 mm and a thickness of 0.3 m / m has a tape feed hole with a 4 mm pitch in the feed direction at one edge and a central hole at the center. A 18 mm × 18 mm square hole with a 20 mm pitch was punched out at room temperature with a punch to produce a connecting tape. Separately, a polypropylene in which a conductive material is kneaded is injection-molded to have an outer diameter of 19 × 19 mm, a depth of 2 mm, and a recess size of 16.8 × 16. A large number of IC storage containers each having a ridge of 8 mm, bottom projection size of 14 × 14 mm, and height of 0.25 mm were prepared. This storage container was inserted into the square hole of the connecting tape and bonded by heat sealing to manufacture an electronic component storage band.

[0016]

Since the hole pitch accuracy and the dimensional accuracy of the electronic component storage band are remarkably high, they have excellent practical value.
