Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a storage band for chip-shaped electronic components, and more particularly to a storage band that stores chip-shaped electronic components in a form that facilitates automatic mounting on a printed circuit board or the like.

Conventionally, most electronic components have lead wires attached to them. However, the recent trend in various electronic devices is to make them ultra-thin and ultra-small. In order to respond to this trend, improvements have been made in various parts of electronic devices, and these improvements have spread to the point where the lead wires of electronic components occupy as little as possible. Chip-type electronic components without lead wires are advantageously used for this purpose. This is applied, for example, to a multilayer capacitor, and an external electrode is formed on one surface of the capacitor. Such chip-shaped electronic components are directly soldered to a wiring board or the like through their external electrodes, thereby being electrically and mechanically connected to the wiring board or the like.

Feeding the chip-shaped electronic components to the wiring board as described above requires alignment, so it has been done manually or using a parts feeder. As a result, it is time-consuming, difficult to automate, and has low reliability and reliability.

For this purpose, for example, a magazine method or a pallet method has been proposed. FIG. 1 is a sectional view showing the magazine, and FIG. 2 is a perspective view showing the pallet. In the magazine system, chip-shaped electronic components 2 are supplied by a magazine 3 in which a plurality of chip-shaped electronic components 2 are stacked and stored in a cylindrical storage body 1 . In the pallet system, chip-shaped electronic components 2 are supplied by a pallet 6 in which chip-shaped electronic components 2 are stored in each recess 5 of a flat storage body 4 having a plurality of recesses 5 in the vertical and horizontal directions. It is something. These storage bodies 1 and 4 are made of aluminum or plastic, and have fixed lengths, dimensions, and
It is something that has area etc. However, in these systems, the amount of pooled magazines 3 and pallets 6 is small, requiring frequent replacement, and even if the chip-shaped electronic components 2 are automatically taken out, handling of the magazines 3 and pallets 6 becomes difficult. Furthermore, when automatically taking out the chip-shaped electronic component 2, it is necessary to feed or pull out the electronic component 2, and a device for feeding, pulling out, or positioning is required. Furthermore, in the magazine type, since adjacent chip-shaped electronic components are in contact with each other, the electronic component 2 may be damaged due to this contact.

Therefore, the main object of the present invention is to provide a chip-shaped electronic component storage band that can solve the above-mentioned problems.

In summary, the present invention includes a plurality of through holes and perforations formed at equal intervals along the longitudinal direction.
A tape-like body provided so that these do not overlap each other along the longitudinal direction, and a tape-like body that is attached to both planes of this tape-like body and seals the through hole, but does not seal the perforation hole. This chip-shaped electronic component storage band is characterized by comprising a cover sheet having a width narrower than the body, and chip-shaped electronic components stored in a storage portion formed by the cover sheet and a through hole.

Other objects and features of the present invention will become more apparent from the detailed description given below with reference to the drawings.

FIG. 3 shows the manufacturing process of the chip-shaped electronic component storage band according to the present invention, and FIG. 4 is a perspective view showing the rolled state of the obtained storage band.

The chip-shaped electronic component storage band shown here includes a tape-shaped body 10 made of paper, plastic, metal such as iron or aluminum, or rubber. Preferably, a flexible material that is easy to wind is used as shown in the fourth figure. A plurality of through holes 11 are formed along the longitudinal direction of the tape-shaped body 10.
The plurality of through holes 11 are mutually independent from adjacent ones, and are formed at regular intervals. Also,
The through hole 11 is formed by, for example, punching the tape-shaped body 10. Reference numeral 12 denotes a plurality of perforations provided at equal intervals in relation to the arrangement pitch of the through holes 11 of the tape-like body 10. For example, this can be done simultaneously with the formation of the through holes 11 and by the same means. This feed hole 12 is provided at a position that does not overlap with the through hole 11 along the longitudinal direction of the tape-like body 10. This makes the positional relationship and dimensional accuracy between the through hole 11 and the feed hole 12 extremely good. This feed hole 12 is used when pitch-feeding the tape-like body 10 during processing of the tape-like body 10 or during automatic mounting of electronic components, which will be described later. A thin cover sheet 13 is attached to one surface of such a tape-like body 10. This cover sheet 13 has the through holes 11
The sprocket hole 12 constitutes one of the lids.
The tape-shaped body 10 is not present in the area where the spout hole 12 is formed, and is made so as not to cover the feed hole 12.
A width narrower than that is used. This is to stabilize and improve the feeding accuracy of the tape-shaped body 10, and the details will be described later. This cover sheet 13 can be attached by, for example, a so-called heat sealing method, in which a thin plastic film is used as the cover sheet, and this is brought into contact with and superimposed on the tape-shaped body 10, and then heated and melted to attach it. Although it is convenient, it may be attached using an adhesive or the like. However, it goes without saying that it is necessary to prevent the chip-shaped electronic components accommodated in the through holes 11 from being bonded to the cover sheet 13. Note that the above-mentioned pasting does not have to be done on the entire cover sheet 13;
It is sufficient to do this so that the through hole 11 can be covered. For example, only both sides of the tape-like body 10 in the width direction may be heat-sealed by heating and welding them in a linear manner. However, since this cover sheet 13 constitutes the bottom of the storage section for chip-shaped electronic components, as will be described later, it is deformed by external force applied when storing and removing electronic components, making it easy to change the shape of the storage section. It is preferable to attach the entire surface to prevent the electronic components from being deformed and making it difficult to store and take out the electronic components.

One chip-shaped electronic component 2 is housed in each through hole 11 whose one open end is covered by a cover sheet 13, with its orientation and front and back sides determined.

A thin cover sheet 14 is also attached to the other plane of the tape-like body 10 in which the electronic component 2 is housed. This cover sheet 14 constitutes the other lid of the through hole 11, and it also covers the feed hole 1.
2 is formed in the longitudinal direction 10 so as not to cover this feed hole 12.
A width narrower than that is used. As a result, a housing section is formed by both cover sheets 13, 14 and the through hole 11, and the chip-shaped electronic component 2 is housed in this housing section. This cover sheet 14 is similar to the above-mentioned cover sheet 13, but it is peeled off from the tape-like body 10 when the electronic component 2 is to be taken out, which will be described later, and this peeling is easy and good. In order to be able to do this, it is particularly preferable that the adhesive is not attached to the tape-like body 10 over the entire surface, but only on both sides of the tape-like body 10 in the width direction, for example, in a linear form. This pasting means may be any method such as a method using the above-mentioned adhesive or a heat sealing method.

The chip-shaped electronic component storage band of the present invention is constructed as described above, and for example, as shown in FIG.
A winding core 15 or a reel (not shown) is prepared as appropriate, and the core 15 is wound spirally around its circumferential surface. Although not shown, the storage bands may be folded in a so-called zigzag manner and overlapped. Therefore, a large number of chip-shaped electronic components 2
It can be packed compactly, transported in that state, and mounted on an automatic mounting device, etc. as it is. The longer the tape-like body 10 is, the more chip-shaped electronic components 2 can be stored, so that the supply state can be maintained for a long time with one exchange of such a storage band. can.

Next, a case will be described in which the chip-shaped electronic component 2 is actually handled by an automatic mounting device or the like using the storage band having such a structure. First, the tape-shaped body 10 is sequentially fed out by adapting the feed hole 12 provided in the tape-shaped body 10 to a feeding mechanism such as a sprocket (not shown). In this case, the feed hole 12 is connected to the tape-shaped body 10.
Since the dimensional accuracy is always constant, the feeding accuracy of the feeding mechanism can be extremely stabilized. In other words, if there is a cover sheet 13 or 14 around the feed hole 12, for example, this will be drawn into the feed hole 12 when the feed mechanism is fitted, and will substantially change the diameter of the hole. As a result, the feed accuracy becomes unstable. Next, one cover sheet 14 stuck to the tape-like body 10 is peeled off by appropriate means, and the chip-shaped electronic component 2 stored in the storage section is exposed. In this case, if the cover sheet 14 is attached only to both sides of the tape-like body 10 in the width direction, the peeling force can be applied almost uniformly over the entire length, and the peeling force in the automatic machine Not only is this easier, but unnecessary vibrations are not imparted to the tape-shaped body 10, and there is no fear that the electronic components contained therein may come out. In other words, if the entire surface of the cover sheet 14 is adhered to the tape-like body 10, there will be a difference in the adhesion force between the portion of the through hole 11 and the portion where the through hole 11 is not formed in the width direction. The difference in adhesion strength makes peeling off the cover sheet 14 unstable. In other words, if you try to continuously peel off objects with different adhesion strengths using the same peeling force, the parts that are peeled off will naturally wave intermittently, causing unnecessary vibrations. . Next, a suction chuck or the like of an automatic machine is placed on the electronic component in the storage section exposed by tearing off the cover sheet 14, and the electronic component 2 is taken out.
It is mounted on a printed circuit board or the like. In this case, if the entire surface of the cover sheet 13 constituting the bottom of the storage section is adhered to the tape-like body 10, when the electronic component 2 is taken out by the suction chuck or the like, the bottom will be pushed downward. Even if a certain amount of pressure is applied, the electronic component 2 will not be easily deformed to a large extent, so the electronic component 2 can be taken out in a stable state, which is advantageous. If the bottom portion is significantly deformed, the electronic component 2 may be tilted or turned upside down in the storage portion, which is undesirable because it impedes workability.

FIG. 5 is a sectional view for explaining another embodiment of the present invention, and is a view cut in the width direction of the storage band. The chip-shaped electronic component storage band shown here includes a tape-shaped body 20 having two rows of through holes 21a and 21b. This tape-like body 20 has cover sheets 23 and 24 on both planes as in the case described above.
A feed hole 22 is also provided. According to this embodiment, twice the number of chip-shaped electronic components 2 can be accommodated in a certain length of the tape-shaped body 20. From this meaning, it will be understood that the through holes may be provided in multiple rows.

Note that the above-mentioned embodiments specifically illustrate the present invention, and do not limit the present invention. For example, there may be multiple rows of perforations provided in the tape-like body, or they may be notches provided at equal intervals on the side edges of the tape-like body instead of through holes. Furthermore, although the arrangement pitch of the feed holes is selected to be the same number as the number of through holes, the arrangement pitch is not limited to this, and may be provided every two through holes, for example.

As described above, the chip-shaped electronic component storage band according to the present invention individually and continuously stores a large number of chip-shaped electronic components in the storage section formed by the through hole of the tape-shaped body and the cover sheet. This allows for continuous handling by automatic machines such as automatic manufacturing machines and automatic mounting machines for long periods of time, thereby increasing the operating rate of the machine and significantly increasing productivity. In addition, in this invention, the cover sheet attached to both sides of the tape-like body seals the through-holes of the tape-like body and does not seal the sprocket hole, so the dimensional accuracy of the sprocket hole is ensured. This allows for excellent feeding by the feeding mechanism of an automatic machine, and for reliable mounting on a printed circuit board or the like. In particular, once the sprocket hole and the through hole are formed in a predetermined positional relationship by simultaneous punching, the positional relationship will no longer be disrupted by other factors, and it will always be stable and good. Can be handled. In addition, in this invention, the cover sheet that is torn off when taking out the stored electronic components is not attached to the tape-like body over its entire surface, but is attached in a linear manner only on both sides of the tape-like body in the width direction. If the sheet is adhered, the adhesion force of the sheet will be substantially uniform over the entire length, and the peeling mechanism in an automatic machine can be simplified. Furthermore, since this cover sheet can be peeled off smoothly, unnecessary vibrations are not applied to the tape-like body, so electronic components do not fly out from the storage compartment opened by peeling off, and the stability is maintained. You can perform various operations. For these reasons, the storage belt of the present invention can accurately supply chip-shaped electronic components during automatic mounting, making it possible to mount them two to three times faster than conventional mounting with high reliability. In addition, this invention has the effect that the number of stored electronic components can be determined by the length of the storage band, and that deterioration and damage of electronic components can be avoided all the way up to the time of mounting. This is an invention with great effects.
