Description

[Detailed Description of the Invention] The present invention relates to a reel for winding tape containing small electronic components such as chip-shaped capacitors and resistors.

This type of reel is a disposable reel that is discarded after the tape has been rewound and electronic components have been placed in the device. The disadvantages were that it generated powder and the side plate of the reel broke. The present invention eliminates these drawbacks and provides a reel for electronic component storage tape that provides other advantages such as easy tape mounting, light weight, low cost, and mass production.

To explain using the drawings of an embodiment, the present invention has a hole 6 for shaft insertion in the center of a circular thin plate 1 of plastic, and a recess 2 concentric with the circular shape in the periphery near the hole. , the outer plane part 4
A plurality of protrusions 5 are provided in the recess 2, and a plurality of protrusions 3 are provided in the recess 2 to cross the recess in the radial direction, and a flat surface 4 that is paired with each of the protrusions 3 of the recess and close thereto is used for tape manipulation. The two circular thin plates 1 and 1' obtained in this way are stacked so that the protrusions 3 and 3' of the recesses are positioned symmetrically, respectively, and the back sides of both the recesses 2 and 2' are formed. An electronic component storage tape characterized in that a tape insertion hole 9 is formed by joining the protrusions 3, 3' of both the recesses in the roll body 8 formed by the recesses 2, 2' by joining them together. Relating to reels for use.

The present invention provides uneven portions on a thin plastic plate by compression molding into an uneven shape, and the uneven portions appear in reverse on the front and back sides of the thin plate. Therefore, when the recess 2 and the protrusions 3 and 5 are viewed from the back side, they become a protrusion and a recess, respectively. Compression molding into the uneven mold is performed by vacuum molding, pressure molding, press molding, or the like.
The shape of the recess 2 is usually circular, but may also be polygonal. The method of joining the two circular thin plates on the back side of the recess 2 is by resin adhesion, welding, on-men joining, or the like.

What is particularly important about the above structure of the present invention is that a circular thin plate of plastic is provided with a concave portion 2 concentric with the circular shape, and a protruding strip 3 is provided in the concave portion radially across the circular thin plate. 1 and 1' are superimposed so that the protrusions 3 and 3' are positioned symmetrically,
This is the point where they are joined on the back side of the recesses 2 and 2'. By joining two circular thin plates on the back sides of the circular or polygonal recesses 2, 2', that is, by joining the recesses back to back, the reel body 8 is formed by the recesses, The other thin plate portion becomes the side plate portion 10 of the reel. By joining the thin plates 1, 1' so that the grooves 3, 3' of the recesses are in symmetrical positions, the protrusions 3, 3' are formed as shown in FIG.
As a result, a tunnel 9 is formed in the winding body 8, and this tunnel becomes an insertion hole at the beginning of tape winding. And, the protrusions 3, 3' are applied to the thin plate,
It serves as reinforcement similar to ribs. One noteworthy feature of the present invention is that the protrusions 3, 3' form the tape insertion hole 9 and at the same time serve to reinforce the thin plate near the center where a large torque is applied.

The protruding line 5 provided on the thin plate plane part 4 is similar to the protruding line 3 of the recessed part.
Similarly, it exerts a reinforcing effect on thin plates similar to that of ribs. As shown in FIG. 1, an appropriate number of these protrusions 5 are provided in the radial direction and the circumferential direction. The shaft insertion hole 6 is for inserting the reel support shaft.

In the present invention, since the holes 7 and 7' for operating the tape are provided near the tape insertion hole 9 formed in the winding body 8, a recess is formed for storing electronic components and the surface is When inserting a non-flat tape into the tape insertion hole 9, the tape operation hole 7,
Insert your finger from 7' and guide the end of the tape to the entrance of tape insertion hole 9. If the tape is difficult to insert,
Do operations such as crushing the unevenness on the tape surface with your fingertips,
By inserting the tape into the tape insertion hole 9, it is possible to easily attach the electronic component storage tape, which is difficult to attach to the reel.

The product of the present invention is made of a thin plastic plate, and this thin plate is reinforced by the protrusions 3 and 5, so it exhibits the hinge effect and spring effect of the side plate part 10 necessary for this type of reel, and is different from the conventional one. The side plates do not break easily like paper reels do, and of course there is no paper dust. Furthermore, since it is a thin plate, it is lightweight, and since it is created by crimping onto a concave-convex mold, it can be mass-produced and is inexpensive. Furthermore, since the product of this invention is obtained by joining two thin plates, the joining can be done by either the reel manufacturer or the user, and joining is extremely simple if on-men joining is used. .
