DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a reel for electronic parts on which a carrier tape for packaging electronic parts containing electronic parts and the like is wound, and more particularly to a core and both ends of the core. And an electronic component reel provided with a flange.

[0002]

2. Description of the Related Art Conventionally, as a reel for this kind of electronic parts, a molded plastic reel formed by injection molding or vacuum molding has been used. Such a molded plastic electronic component reel is manufactured by manufacturing a core mold and a flange mold, casting a melted plastic into these molds and molding to obtain a core and a flange. Was made by bonding. A paper electronic component reel has also been used, for example, an electronic component reel in which a corrugated paperboard flange is bonded to both ends of a hollow cylindrical paper tube (core). Further, there have been proposed reels for electronic components in which a metal clasp is passed through the axis of the reel for electronic components described above, and reels for electronic components in which a corrugated paper flange is bonded to a polystyrene foam core (utility model registration No. 1). No. 3021337). The clasp and the Styrofoam core are molded using a mold for molding into a desired shape, similarly to the molded plastic.

[0003]

However, according to the above-mentioned conventional reel for electronic parts, since a mold is used for molding, the product shape is limited to the shape of the mold. Therefore, when a reel for an electronic component having a special dimension is required, a new mold corresponding to the dimension must be created, and accordingly, the cost of producing a new mold increases. There was a point. Therefore, there is a problem that it is difficult to prepare small lots and various kinds of products in advance or as needed according to demand.

On the other hand, according to the conventional paper electronic component reel described above, since paper dust and the like are easily generated, it is difficult to bring the reel to a place where fine particles are not allowed, such as a clean room. Therefore, this kind of electronic component reel is brought into a clean room, and the electronic component is packed and wound on the electronic component packaging carrier tape, or the electronic component and the like are wound from the wound electronic component packaging tape. Since it is not possible to take out and install the device on a substrate or the like, it takes time and effort to move the electronic component reel, the electronic component, and the substrate between handling locations, which increases the cost. there were. Further, when the corrugated paper reel for electronic components is placed under high-temperature and high-humidity conditions, corrosive gas is generated from the corrugated paper, and the electronic components packaged in the carrier tape for packaging electronic components come into contact with this gas. Therefore, there is a possibility that corrosion may occur and influences such as poor conduction of the terminals of the electronic component and discoloration may occur. Further, the corrugated paperboard and the hollow cylindrical paper tube have a problem that they absorb water, expand, bend, and deform when placed under high humidity conditions. Further, since the bonding surface between the corrugated paperboard flange and the hollow cylindrical paper tube is limited to a very narrow region such as an edge region of the hollow cylindrical paper tube, there is a problem that the bonding strength is low. Was.

[0005] Further, when a material such as the metal or styrofoam which must be separated and discarded from the corrugated cardboard is used for adding strength, etc., disassembly work is performed at the time of discarding, and the material is separated and collected for each material. There is a problem that it takes time and effort. or,
As with the molded plastic described above, a molding die is still required to create the fastener and the styrofoam core. To change the shape of the product, it is enormous to create a new die. There is a problem that high costs are incurred. Therefore, there is a problem that it is difficult to prepare small lots and various kinds of products in advance or as needed according to demand.

SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide an electronic component reel which can be brought into a clean room and can easily obtain various product shapes in view of the above-mentioned drawbacks.

[0007]

According to a first aspect of the present invention, there is provided a reel for an electronic component according to the present invention.
In a core 1 and an electronic component reel provided with flanges 2 and 2 at both ends of the core 1, the core 1 is formed by laminating and adhering a plurality of plastic cardboards 6, and the core 1 1 in that the flange 2 made of plastic cardboard 6 is bonded to both ends. In the above-mentioned characteristic configuration, as described in claim 2, the first fixing hole 11 penetrating through both side surfaces of the core body 1 corresponds to the first fixing hole 11 of the flange 2. And a second fixing hole 21 penetrating therethrough, and the fixing piece 3 extends from the first fixing hole 11 to the second fixing hole 21.

As described above, it is preferable that at least a part of the plastic cardboard 6 is subjected to antistatic processing. And these effects are as follows.

That is, as described in claim 1,
In a reel for an electronic component in which a core body 1 and flanges 2 and 2 are provided at both ends of the core body 1, the core body 1 and the flanges 2 and 2 are made of plastic corrugated cardboard 6. It is not necessary to use an expensive mold like a reel for electronic parts made, and it can be formed by a Thomson mold (Thomson blade) which only punches along the outer shape. The Thomson mold is easier to manufacture than the injection molding and vacuum molding dies and can be procured at a very low cost, so that the cost for changing the product shape can be kept low. Therefore, the core 1 and the flange 2 having various diameters can be easily manufactured. Further, when the core 1 is formed by laminating and bonding a plurality of plastic cardboards 6, the thickness of the core 1 is adjusted by adjusting the number of the plastic cardboards 6 to be laminated according to the width of the carrier tape. Can be easily changed. Then
The core body 1 having a different thickness can be manufactured only by manufacturing one type of the die for punching the plastic corrugated cardboard 6 having the same shape that constitutes the core body 1. Thus, in the electronic component reel according to the present invention, small lots and various kinds of electronic component reels can be easily manufactured at low cost according to demand. In addition, since the core body 1 is formed by laminating the plastic cardboards 6, the bonding surface increases, the bonding strength increases, and the strength can be improved. In addition, since the plastic cardboard 6 is lighter than the molded plastic, by using the plastic cardboard 6 as a constituent material, the weight of the electronic component reel can be reduced. Since the plastic corrugated cardboard 6 constituting the reel for electronic components according to the present invention hardly generates the corrosive gas described above,
It is possible to prevent deterioration of the electronic component due to corrosion.
Further, since dust due to abrasion or the like hardly occurs, it can be brought into a clean room or the like. For example, production of the electronic component, packing of the electronic component on a carrier tape, winding of the carrier tape on the reel for the electronic component, feeding of the carrier tape from the reel for the electronic component, A series of operations such as taking out of the electronic component and installation of the electronic component can be performed in a clean room, preventing damage to the electronic component due to vibration during transportation and changes in the surrounding environment, and preventing transportation. You can save time and effort. Further, since the laminated core 1 and the flange 2 are made of the same plastic corrugated cardboard 6, the flange 2 can be easily bonded to both ends of the core 1. As a result, an electronic component reel having a certain strength can be obtained only by a simple operation of bonding without providing a fastener or the like. In addition, when it is not necessary to provide a fastener or the like, it is possible to eliminate irregularities on the outer surface of the flange 2, and it is easy to bond or closely contact the plurality of reels for electronic components between the outer surfaces of the flange 2. Therefore, the multiple connection can be easily performed, the storage space can be reduced, and the stapling can be easily performed on the device for rotating the reel for electronic components.

In the above-mentioned characteristic configuration, as described in claim 2, a first fixing hole 11 penetrating through both side surfaces of the core body 1 and the first fixing hole 1 of the flange 2 are provided.
When the core body 1 and the flange 2 are bonded to each other, the second fixing hole 21 is provided at a position corresponding to the first fixing hole 21 so that an appropriate positional relationship can be obtained. Becomes easier. Further, by tightly fitting the fixing piece 3 from the first fixing hole 11 to the second fixing hole 21, the fixing piece 3 is provided with a reinforcing material penetrating in the axial direction over the entire electronic component reel. As a result, the strength of the core body 1 in the axial direction can be enhanced.

Further, as described in claim 3, it is preferable that the fixing piece 3 is made of plastic corrugated cardboard 6 because it is not necessary to separate and discard the material and it can be integrally disposed.

Further, as described in claim 4, it is preferable that at least a part of the plastic corrugated cardboard 6 is subjected to an antistatic treatment, because the electrostatic breakdown of the electronic component can be prevented. In the claims,
Although the reference numerals are attached to facilitate comparison with the drawings,
