Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a take-up reel used when manufacturing an electronic device using chip parts.
[0002]
[Prior art]
At the time of manufacturing an electronic device using chip parts, as shown in FIG. 4, the chip part 3 stored in the recess 2 formed in the tape body (mounting paper) 1 is taken out and mounted on the printed circuit board of the electronic device. However, at this time, it is necessary to peel off the top tape 4 covering the top surface of the concave portion 2 of the tape body 1 prior to taking out the chip component 3. The top tape 4 is pulled in the direction of the arrow 5 to peel off the top tape 4 and the chip component 3 is taken out. The top tape 4 is wound around a take-up reel 6 and processed as shown in FIG.
[0003]
Hereinafter, a conventional take-up reel will be described. As shown in FIG. 5, the conventional take-up reel 6 is composed of a cylindrical core 7 and a circular hook 8 that is connected to the core 7 and provided on the side surface. The top tape 4 is wound around the core 7.
[0004]
As shown in FIG. 6, the take-up reel 6 is mounted and wound on a ratchet 10 connected to the drive unit 9.
[0005]
The top tape 4 wound around the take-up reel 6 is unnecessary in the manufacture of the electronic device, and the top tape 4 must be removed from the take-up reel 6. For this removal, the end of the wound top tape 4 was held, and the work was manually removed many times.
[0006]
[Problems to be solved by the invention]
However, in such a conventional configuration, when the wound-up top tape 4 is removed from the take-up reel 6, the end of the wound-up top tape 4 is held and removed manually many times. The burden on the workers was great.
[0007]
SUMMARY OF THE INVENTION The present invention is intended to solve such problems, and an object of the present invention is to provide a take-up reel in which the top tape can be easily removed from the take-up reel.
[0008]
[Means for Solving the Problems]
In order to achieve this object, the take-up reel of the present invention comprises a cylindrical core and a circular hook connected to one side surface of the core, and a large span straddling the core and the hook. It is formed by an elastic member while providing a shape cut. Thereby, a top tape can be easily removed from a take-up reel.
[0009]
DETAILED DESCRIPTION OF THE INVENTION
The invention according to claim 1 of the present invention is a take-up reel that peels off the top tape covering the chip component from the tape main body and takes it up before taking out the chip component from the tape main body in which the chip component is stored. The take-up reel includes a cylindrical core and a circular flange connected to one side surface of the core, and a large notch extending over the core and the flange. It is a take-up reel formed of an elastic member, and is provided with a large cut across the core and the collar, and is formed of an elastic member. By pushing the outer shape of the collar, the inner diameter of the core is reduced and wound. The top tape can be easily removed.
[0010]
The invention described in claim 2 is the take-up reel according to claim 1 in which a small notch is provided in a ridge on the symmetrical side of a large incision, and has a notch on the symmetrical side. The wrinkles of the part are easily spread, the inner diameter of the core can be reduced with a smaller pressing force, and the top tape can be removed more easily.
[0011]
The invention described in claim 3 is the take-up reel according to claim 1, wherein a recess is provided inside the symmetrical core of the large cut, and the recess is provided inside the symmetrical core. Therefore, the inner diameter of the core can be reduced with a smaller pressing force, and the top tape can be removed more easily.
[0012]
The invention according to claim 4 is the take-up reel according to claim 1, wherein the opening angle opened toward the outside of the large cut is approximately 15 degrees. Since the top tape can be wound up almost without any loss and an appropriate inner diameter of the core can be obtained, the tape can be easily removed without impairing the performance of the take-up reel.
[0013]
The core and scissors according to the fifth aspect of the present invention are the take-up reel according to claim 1, which is integrally formed, and it is not necessary to fix the core and the scissors with separate members. Moreover, since it is integrally molded, a low-priced take-up reel can be realized.
[0014]
The invention according to claim 6 is the take-up reel according to claim 5, which is made of polypropylene, and is low in cost because it is elastic and the material is inexpensive and can be easily molded. A take-up reel can be realized.
[0015]
The bag of the invention described in claim 7 is the take-up reel according to claim 1 made translucent or transparent, and the amount of the wound top tape can be easily seen from the outside, and the replacement time is easy. Can know.
[0016]
Hereinafter, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a plan view of a take-up reel according to an embodiment of the present invention, and FIG. 2 is a cross-sectional view thereof.
[0017]
In FIG. 1, 11 is a cylindrical core, and 12 is a circular ridge formed integrally with the core 11, both of which are made of polypropylene. 13 is a large cut, which opens from the center of the core 11 to the outside of the flange 12 at an angle of approximately 15 degrees. The opening angle 13a of the cut 13 may be about 10 to 20 degrees.
[0018]
Reference numeral 14 denotes a small cut provided in the flange 12 on the symmetrical side with respect to the core 11 of the cut 13. Reference numeral 15 denotes a recess provided in the core 11 on the symmetrical side of the notch 13.
[0019]
Reference numeral 4 denotes a top tape wound around the core 11 of the take-up reel 16 configured as described above. The take-up reel 16 is mounted on a ratchet 10 connected to the drive unit 9 as shown in FIG. That is, when the drive unit 9 is rotated, the ratchet 10 is rotated, and the take-up reel 16 attached to the ratchet 10 is rotated. As a result, the top tape 4 is wound around the core 11.
[0020]
In this manner, the top tape 4 is peeled off when the chip component 3 housed in the recess 2 of the tape body 1 shown in FIG. 4 is taken out.
[0021]
Next, removal of the top tape 4 taken up by the take-up reel 16 will be described with reference to FIG. In FIG. 3, the operator presses the positions 17 and 18 perpendicular to the notches 13 and 14 of the flange 12 of the take-up reel 16 in the direction of the core 11. Then, the outer shape of the core 11 is reduced, and a gap 19 is formed between the top tape 4 and the core 11. Thereby, the adhesion state of the top tape 4 and the core 11 is eliminated, and the top tape 4 can be easily detached from the core 11.
[0022]
Note that, when the collar 12 is formed of a transparent or translucent member, the state of the wound top tape 4 can be visually observed from the outside, and the time for replacing the take-up reel can be easily known. Further, the size of the take-up reel 16 is approximately as follows. That is, the diameter of the collar 12 is 8 cm, the diameter of the core 11 is 3 cm, and the width is 1 cm.
[0023]
As described above, according to the present embodiment, the outer shape of the core 11 is reduced by pressing the vertical direction (90-degree direction) 17 and 18 against the notches 13 and 14 of the ridge 12, so that the top tape 4 can be easily removed. In addition, since the core 11 and the flange 12 are integrally formed, a member for locking the core 11 and the flange 12 is not required, and it is possible to reduce the price and simplify the parts management. Furthermore, since it is made of polypropylene, moderate elasticity can be obtained.
[0024]
【The invention's effect】
As described above, according to the present invention, a cylindrical core and a circular ridge connected to one side surface of the core are provided, and a large cut is formed across the core and the ridge. In addition, it is formed of an elastic member and is provided with a large notch that straddles the core and the heel, and is formed of an elastic member. The top tape can be easily removed.
