Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a series of electronic components comprising a tape holding a plurality of electronic components distributed in the longitudinal direction, and in particular to The present invention relates to improvements in engagement features formed in the tape, such as perforations provided to feed the reams along their length.

Summary of the Invention The present invention provides an electronic component series including a tape holding a plurality of electronic components distributed in a longitudinal direction, in which a plurality of notches are provided at equal pitches along at least one side edge of the tape. Therefore, this notch is used in place of a conventional feed hole to feed a series of electronic components in the length direction.

BACKGROUND ART As shown in FIG. 6, an electronic component series 1 includes a tape 3 that holds a plurality of electronic components 2 in a longitudinally distributed state. The feed holes 4 are provided at equal pitches.

The electronic component series 1 is fed in its length direction by, for example, a sprocket 6 having a plurality of pawls 5 distributed in the circumferential direction. That is, as shown in FIG. 7, with the pawl 5 fitted into the feed hole 4, the sprocket 6 is rotated in the direction of the arrow 7, thereby feeding the electronic component series 1.

In the process of feeding the series of electronic components 1, the electronic components 2 are taken out from the tape 3 and supplied to the tape 3. Therefore, the electronic component series 1 in the feeding process
The positioning of the electronic component 2 is an important factor in whether or not the above-mentioned electronic component 2 can be smoothly removed and supplied. To do this, first, the pawl 5 provided on the sprocket 6 must be
However, as shown in FIG. 7, it must fit snugly into the sprocket hole 4.

Problems to be Solved by the Invention However, when tension is applied to the tape 3 made of, for example, cardboard, the tape 3 may be stretched, albeit slightly. Such tension is often encountered during the process of transporting the series of electronic components 1. Therefore, as shown in FIG. 8, the position of the sprocket hole 4 may be misaligned with respect to the position of the pawl 5 of the sprocket 6, and the pawl 5 may not fit perfectly into the sprocket hole 4. As a result, the tape 3 may be damaged at a portion of the peripheral edge of the feed hole 4 where the claw 5 is partially engaged. Furthermore, if such positional deviations are superimposed, the claw 5 may not be able to enter the feed hole 4 at all, and in that case, feeding of the tape 3 itself becomes impossible.

SUMMARY OF THE INVENTION The present invention aims to solve the above-mentioned problems, and aims to provide an electronic component series that can improve feeding accuracy.

Means for Solving the Problems In an electronic component series including a tape holding a plurality of electronic components in a longitudinally distributed state, the present invention includes the following steps.
The tape is characterized in that a plurality of notches are provided at equal pitches along at least one side edge of the tape.

Effects of the Invention According to the present invention, when feeding a series of electronic components, a notch provided along the side edge of the tape is used in place of the conventional feed hole. Therefore, the claw-like engaging means provided on the drive means for feeding the series of electronic components can be actuated from the side of the tape.

As a result, even if a misalignment occurs between the notch and the engagement means provided in the drive means, the tape 3 will not be lifted up as shown in FIG.

This is because the engaging means provided in the drive means acts on the tape from the sides, and the forces from the sides are more sensitive to forces than from the top and bottom of the tape as shown in FIG. , because the tape is stronger and can withstand deformation. Therefore, even if a positional deviation occurs between the notch and the engaging means, the positional deviation can be promptly corrected by fitting the engaging means into the notch. for that,
Improves accuracy when sending electronic components.

Furthermore, since the tape does not require space for providing feed holes as in the past, the width of the tape can be made narrower, and the tape material can be saved.

Further, if the tape is notched, as described above, the engaging means can always be properly fitted, and therefore the tape is prevented from being damaged when being fed through the retaining means.

Example One embodiment of the invention is shown in FIG.

The electronic component 1!11 shown here includes a plurality of chip-type electronic components 12. In order to hold the electronic component 12, a tape 13 made of cardboard, for example, is prepared,
There, a plurality of cavities 1 are distributed along its length.
4 are provided, and an electronic component 12 is placed in each cavity 14.
is stored. The cavity 14 is closed by a top cover sheet 15 and a bottom cover sheet 16 attached to the upper and lower surfaces of the tape 13, respectively.

Note that when the electronic components 12 are supplied into the cavity 14, the bottom cover sheet 16 is already attached to the tape 1.
On the other hand, when taking out the electronic component 12 inside the cavity 14, the top cover sheet 1
5 is in a peeled state.

When paying attention to both side edges of the tape 13, a plurality of notches 17 are provided at equal pitches on each side edge. The notch 17 shown here has a ■-shape. These notches 17 perform the same function as the conventional feed hole 4 (FIGS. 6 to 8).

In order to provide the notch 17, it is not necessary to intentionally increase the width of the tape 13. In particular, as in the embodiment shown in FIG.
The width of the tape 13 can be made even narrower by locating the notch 17 between two adjacent cavities 14. By providing such a notch 17 in place of the conventional sprocket hole, for example, the width of the tape, which conventionally required 81 mm, can be reduced to 5.5 mm, and the width of the conventional tape, which was 12111@, can be reduced to 9 mm. .5+am, resulting in material savings of 31% and 21%, respectively.

Next, various examples of feeding methods for the electronic component series 11 shown in FIG. 1 will be explained.

2 and 3 show a first example of the feeding method. One side edge of the electronic component series 11 is provided with a drive wheel 20 held by a vertically oriented shaft 19 so as to be in contact with a vertical wall 18 and act on a notch 17 provided in the other side II. It will be done. A plurality of teeth 21 are provided on the outer peripheral surface of the drive wheel 20. As clearly shown in FIG. 3, when the drive wheel 20 is rotated in the direction of the arrow 21 while the tooth 21 is fitted into the notch 17, the electronic component chain 11 is fed in its length direction. It will be done.

In addition, as shown in FIG. 3, since the notch 17 is formed in a V-shape when viewed in plan, the shape of the tooth 21 is also
It is preferable to have an inclined surface that contacts this V-shaped notch on two surfaces. By doing so, when the drive wheel 20 pushes the tape 13 toward the vertical wall 18, the teeth 21 and the notches 17 come into closer contact, and the tape 13 can be positioned with higher precision.

Note that the above-mentioned advantages are not only obtained when the notch 17 is formed in a V-shape with two mutually intersecting planes.

For example, the planar shape of the notch may be U-shaped, which is slightly rounder than the square square shape. Furthermore, even if the planar shape of the notch is square and mouth-shaped, substantially the same advantage can be brought about by forming a taper or radius in the planar shape of the tooth 21.

FIG. 4 shows a second example of the feeding method for the electronic component series 11. Also in this example, one side edge of the tape 13 is brought into contact with the vertical wall 23. A claw 24 is arranged to fit into a notch 17 provided on the other side edge of the tape 13 . The pawl 24 is swingably held by a pin 27 on a driver 26 that is reciprocated in the direction indicated by a double-headed arrow 25 . Further, the pawl 24 is biased by a spring or the like (not shown) so as to rotate in the direction of the arrow 28. Therefore, by reciprocating the driving body 26 in the direction of the arrow 25, the electronic component series 11 is intermittently driven in the direction of the arrow 29.

FIG. 5 shows a third example of the feeding method for the electronic component series 11. In this example, two parallel drive wheels 32 , 33 are used which are both rotationally driven in the direction of arrow 31 by a common shaft 30 .

On the outer peripheral surface of each drive wheel 32, 33, there are teeth 34, respectively.
．． 35 are distributed. Each tooth 34, 35 is selected to fit closely within a notch 17 provided on each side edge of the tape 13, respectively. Therefore, both driving wheels 32,
When 33 is rotated in the direction of arrow 31, the electronic component chain 11 will be fed along its length, with the teeth 34.35 fitting into the notches 17.

In the feeding system shown in FIG. 5, only one drive wheel, for example the drive wheel 32, may be used, and the other drive wheel 33 may be replaced by a vertical wall that abuts the side edge of the tape 13.

Furthermore, as can be inferred from the feeding method shown in FIG. 5, in the feeding method shown in FIGS. 2 and 3, vertical! ! Instead of 18, another drive wheel may be arranged symmetrically with drive wheel 20. Also, in the feeding method shown in Figure 4, vertical!
! Instead of the claw 23, another claw may be arranged symmetrically with the claw 24.

Further, as can be seen from the two feeding methods shown in FIGS. 2 to 4, the notch 17 may be provided only on one side edge of the tape 13.

Furthermore, the electronic component chain provided with the notch, which is a feature of the present invention, may be of any type as long as it is provided with a tape for holding the electronic component, and is shown in FIG. An electronic component series 1 comprising a top cover sheet 15, a bottom cover sheet 16, and a tape 13 as shown in FIG.
It does not have to be 1. For example, bottom cover sheet 16
The bottom wall of the cavity 14 corresponding to the tape 13 may be formed integrally with the tape 13 by resin molding.

Furthermore, the electronic component held by the tape is not limited to a chip type, and may be an electronic component having lead wires.
