Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a carrier tape reel used for winding a carrier tape containing an electronic component such as a semiconductor chip.

[0002]

[Prior Art]

 Conventionally, a carrier tape is made of a conductive material to protect the stored electronic components, and for the same reason, a carrier tape reel for winding the carrier tape is also made of a conductive or antistatic elastic plastic material. Although it has been used, the dimensional accuracy of the carrier tape reel is not sufficient, which causes problems such as deformation during use. Recently, materials with higher rigidity than before have been desired. In the conventional reel, since the flange and the hub cylinder are individually formed, and they are integrated by melting or adhering them, it takes time to manufacture and assemble, and there is a problem in cost.

[0003]

[Problems to be solved by the device]

 In view of this point, the present invention intends to provide a reel for a carrier tape, which is made of a conductive and highly rigid plastic material and has a simple structure and is extremely easy to assemble.

[0004]

[Means for Solving the Problems]

 The present invention solves the above problems by using reel members of the same shape and size. That is, the present invention relates to a carrier tape reel having a structure in which a pair of reel members having the same shape and size and having a flange 2 and a hub 3 are reversed and combined so as to face each other. On the end surface of the hub 3, a pair of male holes 4 having an annular projection 6, a pair of female holes 5 mating with the male holes 4, a hook-shaped locking piece 7, and a receiving window 8 having a tongue piece 9 are provided. The gist of the present invention is a carrier tape reel characterized in that the tape insertion grooves 10 are arranged to face each other.

The present invention will be described in detail below. The reel for carrier tape of the present invention is a high-rigidity plastic molded product, which comprises a hub and a reel member of the same size and the same size, which comprises a flange concentric with the hub. Combined with. As the plastic material, a material composition having high rigidity is selected from polystyrene, polycarbonate, polyacetal, polymethylmethacrylate, acrylonitrile and the like.

To the composition of these plastic materials, carbon black, graphite, carbon fiber, metal powder or the like can be added as a filler for imparting conductivity. Further, a known antistatic agent may be contained, and the reel after carrier is optionally coated or coated to form a reel for carrier tape.

Next, one embodiment of the present invention will be described with reference to the accompanying drawings. The reel of the present invention has two reel members, which are composed of a flange 2 and a hub 3 around an axis 1 as a component. As shown in FIGS. 1 (a) and 1 (b), the flange 2 has fan-shaped openings 12 arranged evenly around the hub 3, and spoke-shaped reinforcing ribs 13 are provided on the remaining portion. . If the rib portion is covered with a thin film to form a blind shape as shown in (a), various indications such as product numbers and labels can be attached thereto. In the case of forming a blind shape with a thin film, it is preferable to appropriately devise the position and size of the carrier tape so that the wound state of the carrier tape can be visually observed.

In the hub 3 which constitutes the main part of the present invention, male holes 4 and female holes 5 are arranged opposite to each other with the shaft core 1 as a center in both side regions sandwiching the tape insertion groove 10. As shown in FIGS. 1 and 2 (b), the male hole 4 has an annular protrusion 6 to which the female hole 5 is connected. Each of the male hole 4 and the female hole 5 may be one in number, but it is preferable to arrange two in parallel. A hook-shaped locking piece 7 and a receiving window 8 are provided on both sides of the male hole 4 and the female hole 5, respectively, on the circumference of the end face of the hub 3. As shown in FIG. 4, this hook-shaped engaging piece 7 is provided so as to project above the hole 14, the outer two surfaces are released and the inner two surfaces are closed, and the cross section is key-shaped.

The receiving window 8 also has a substantially arcuate shape along the circumference, and a tongue piece 9 is attached to the end thereof. The inclination angle θ between the tip of the hook-shaped locking piece 7 and the tip of the tongue piece 9 is not particularly limited as long as the locking is performed smoothly, but both are set to about 15 degrees in this embodiment. Is to improve the connection between the two.

The structure of the reel member for carrier tape of the present invention is as described above. To assemble the reel member, first, one of the two reel members is inverted and the hub surfaces are opposed to each other. When they are overlapped as shown, the female hole 5 and the male hole 4, and the receiving window 8 and the hook-shaped locking piece 7 are slightly displaced and overlap each other. Then, when it is rotated about 10 degrees, the tongue piece 9 is inserted into the hook-shaped locking piece 7 that has entered from the receiving window 8 as shown in FIG. In this case, since the tips of both of them are inclined by 15 degrees, the rigid tongue piece 9 is slightly bent and forcibly inserted into the hook-shaped locking piece 7, and at the same time the annular projection 6 of the male hole 4 is inserted. Since it fits into the female hole 5, extremely strong connection and integration can be achieved in an instant, and the reel for carrier tape of the present invention can be obtained.

[Effect of the device]

 According to the present invention, since the reel component member is a molded product of the same shape and size with a simple structure, the manufacturing cost is much lower than the conventional product, the rigidity is excellent, the dimensional accuracy is excellent, and the assembly is easy. A reel with no deformation can be obtained.
