Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a taping body in which a plurality of radial lead type electronic components are combined with an adhesive tape.

[0002]

2. Description of the Related Art A conventional taping body will be described.
FIG. 3 is a front view of the taping body. Reference numeral 1 denotes an electronic component in which two parallel lead wires 1b extend from the main body 1a.
Reference numeral 2 denotes a tape mount, and reference numeral 3 denotes an adhesive tape bonded to the tape mount 2.

[0003] The tape body is formed by connecting the lead wires 1b of each electronic component 1 to the tape so that the main bodies 1a of a plurality of electronic components 1 arranged at equal intervals protrude from one side edge of the tape mount 2 and the adhesive tape 3. The backing sheet 2 and the adhesive tape 3 are sandwiched by bonding. At this time, each lead wire 1
b is located parallel to the width direction of the tape mount 2 and the adhesive tape 3, and at least half of its length is sandwiched between the tape mount 2 and the adhesive tape 3.

[0004] At the center in the width direction of the tape mount 2 and the adhesive tape 3, a plurality of feed holes 4 are formed at regular intervals in the length direction. A projection of a transfer member (such as a gear) for feeding the taping body in the length direction is fitted into the feed hole 4. The transport member is provided in a mounting machine for separating the electronic component 1 from the taping body and mounting the electronic component 1 on a printed circuit board.

[0005] The taping body is stored and transported in a folded state.

The length of the tape body 2 in the width direction of the tape mount 2 is 18 to 20 mm, and the diameter of the feed hole 4 is 4 mm. The pitch between the centers of the feed holes 4 is standardized to 12.7 mm according to JIS (Japanese Industrial Standard).

[0007]

In the above taping body, since the projection of the conveying member fits into the feed hole 4, the feed hole 4
The electronic component 1 must be arranged avoiding the feed hole 4 so that the lead wire 1b does not hang. Therefore, as shown in FIG. 3, the electronic component 1 is arranged only between the perforations 4. However, in such a configuration, the tape mount 2 and the adhesive tape 3 have many useless portions, and the tape mount 2 and the adhesive tape 3 are long.

The present invention has been made in view of the above problems, and has as its object to provide a taping body in which the arrangement of electronic components is not restricted by a perforation hole.

[0009]

In order to achieve the above object, a taping body according to the present invention comprises a plurality of electronic components each having a lead wire extending from a main body, and a tape mount and an adhesive tape bonded to each other. The main bodies of a plurality of electronic components are arranged at regular intervals along one longitudinal edge of the tape mount and the adhesive tape. Here, a plurality of feed holes are formed at equal intervals near the other side edge in the tape mount and the adhesive tape.

[0010] In this taping body, since the perforation hole is formed near the other side edge, the distance in the width direction from the perforation hole to one side edge is longer than in the prior art in which the perforation hole is formed at the center in the width direction. . Therefore, even if the electronic components are arranged so as to be aligned with the feed holes in the width direction, a lead wire having a sufficient length can be sandwiched between the tape mount and the adhesive tape.

Further, another taping body of the present invention comprises a plurality of electronic components each having a lead wire extending from a main body, which are sandwiched between the lead wires by bonding a tape mount and an adhesive tape. A plurality of electronic component bodies are arranged at equal intervals along one side edge in the length direction of the tape mount and the adhesive tape, and a feed hole is formed at the center in the width direction of the tape mount and the adhesive tape in the length direction. It is formed at intervals. Here, among the plurality of electronic components, an electronic component in which the perforation hole is located in the direction in which the lead wire extends extends along the side of the perforation hole by bending the lead wire in the middle.

In this taping body, in the case of an electronic component having a perforation hole in the direction in which the lead wire extends, the lead wire is bent in the middle to avoid the perforation hole. Therefore, the projection of the transport member provided in the mounting machine can be fitted into the feed hole.

[0013]

Embodiments of the present invention will be described below with reference to the drawings. In each figure, members having the same names as those of the prior art shown in FIG. 3 are denoted by the same reference numerals.

First, a first embodiment will be described. FIG. 1 is a front view of the taping body of the present embodiment. This taping body connects the lead wire 1b of each electronic component 1, 1 'to the tape mount 2 so that the main body 1a of the plurality of electronic components 1, 1' protrudes from one side edge of the tape mount 2 and the adhesive tape 3. It is sandwiched by sticking the adhesive tape 3 together. At this time, all the electronic components 1 and 1 ′ are arranged at equal intervals, and the respective lead wires 1 b are positioned parallel to the width direction of the tape mount 2 and the adhesive tape 3. The electronic component 1
And the electronic component 1 'have exactly the same configuration.

A plurality of feed holes 4 are formed at equal intervals near the other side edges of the tape mount 2 and the adhesive tape 3. The distance L in the width direction from the center of the feed hole 4 to the other side edge of the tape mount 2 is 2 times the length of the tape mount 2 in the width direction.
It is preferably 0% to 40%.

That is, the distance in the width direction from the perforation hole 4 to one side edge is longer than that of the prior art shown in FIG. 3 in which the perforation hole 4 is formed at the center in the width direction. Therefore, among the plurality of electronic components 1 and 1 ′, the electronic component 1 ′ arranged in the width direction with the feed hole 4 so that the lead wire 1 b does not cover the feed hole 4 is
As with the other electronic components 1, at least half of the length of the lead wire 1 b is sandwiched between the tape mount 2 and the adhesive tape 3.
Therefore, there is no possibility that the electronic component 1 ′ will fall off the tape mount 2 and the adhesive tape 3.

In the taping body of this embodiment, the electronic component 1 ′ is arranged in the width direction with the feed hole 4 by forming the feed hole 4 near the other side edge of the tape mount 2 and the adhesive tape 3. it can. Therefore, the number of electronic components 1 sandwiched per unit length of the tape mount 2 and the adhesive tape 3 is twice that of the prior art shown in FIG. That is, the electronic components 1, 1 'can be efficiently sandwiched between the tape mount 2 and the adhesive tape 3, and the length of the taping body can be reduced by that much.

Next, a second embodiment will be described. FIG. 2 is a front view of the taping body of the present embodiment. The taping body is configured such that the lead wire 1b of each electronic component 1, 1 '' is taped such that the main body 1a of the plurality of electronic components 1, 1 '' protrudes from one side edge of the tape mount 2 and the adhesive tape 3. The backing paper 2 and the adhesive tape 3 are sandwiched by bonding. A plurality of feed holes 4 are formed at equal intervals in the center of the tape mount 2 and the adhesive tape 3 in the width direction.

Among the plurality of electronic components 1 and 1 ″, in the electronic component 1 ″ in which the feed hole 4 is located in the direction in which the lead wire 1 b extends, the two lead wires 1 b are bent immediately before the feed hole 4. The lead wire 1b passes through the side of the feed hole 4 so that the interval between the lead wires 1b from the bent portion to the tip is wider than the other portions. Thereby, the lead wire 1b can avoid the feed hole 4.

The taping body of the present embodiment has a lead wire 1
By using the electronic component 1 ″ formed so that b avoids the feed hole 4, the electronic component 1 ″ can be arranged side by side with the feed hole 4 in the width direction. Therefore, similarly to the first embodiment, the electronic component 1 can be efficiently held between the tape mount 2 and the adhesive tape 3.

Further, since the lead wire 1b of the electronic component 1 ″ is bent immediately before the feed hole 4, the portion exposed from the tape mount 2 and the adhesive tape 3 is identical to any of the electronic components 1, 1 ″. The intervals are the same. Therefore, in a state where the lead wire 1b of the electronic component 1 '' is cut off from the portion sandwiched between the tape mount 2 and the adhesive tape 3 to be mounted on the printed board, there is no difference from the other electronic components 1, so the same is true. Can be implemented.

In the first and second embodiments, the length in the width direction of the tape mount 2 and the diameter of the feed hole 4 are the same as those in the prior art.

Next, a method of fabricating the taping bodies of the first and second embodiments will be described. In the case of the first embodiment, first, the electronic components 1, 1 'conveyed by the chuck are sequentially placed on the tape mount 2 unwound from the reel. At this time, the polarities of the electronic components 1, 1 'are checked in advance, and the electronic components 1, 1' are arranged so that the polarities are arranged in the same direction.

Then, the adhesive tape 3 similarly drawn out from the reel is affixed on the tape mount 2 on which the electronic components 1, 1 'are mounted, and thermocompression bonding is performed to enhance the adhesiveness. Finally, a perforation hole 4 is formed at a predetermined position on the tape mount 2 and the adhesive tape 3 which are bonded together.

In the case of the second embodiment, the electronic component 1
After a step of forming the electronic component 1 ″ by forming the lead wire 1b into a predetermined shape is performed in advance, a taping body is manufactured in the same step as the method of the first embodiment described above. That is,
Since the electronic components 1 in which the interval between the two lead wires 1b is constant from the root to the tip are sequentially sent, the apparatus for forming the lead wires 1b determines the electronic components 1 to be sent every other one by a program. To bend. As a result, the unformed electronic component 1 and the formed electronic component 1 ″ are sent to the next step in a state of being alternately arranged.

Then, these electronic components 1, 1 '' are mounted on the tape mount 2 by the chuck in the order in which they were sent, and thereafter the same steps as in the first embodiment are performed. As a result, as shown in FIG. 2, a taping body in which the unformed electronic components 1 and the formed electronic components 1 ″ are alternately arranged.

[0027]

As described above, the taping body of the present invention can arrange electronic components not only between the perforations but also in the width direction of the perforations. Therefore, even if the taping body holds the same number of electronic components as in the prior art, the lengths of the tape mount 2 and the adhesive tape 3 can be shorter than in the prior art. Therefore, its bulk is reduced and it is convenient for storage and transportation. Also, costs are reduced.
