Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a storage belt for chip-shaped electronic components, and more particularly, to a storage belt 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 linearly soldered to a wiring board or the like via 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 complicated, 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, these methods have a small pool of magazines 3 and pallets 6 and require frequent replacement. Even if the removal of chip-shaped electronic components 2 is automated, the magazine 3
Handling of pallet 6 and pallet 6 becomes a difficult point. In addition, when the chip-shaped electronic component 2 is automatically taken out, the electronic component 2
It is necessary to send out or pull out the material, and a device for feeding, drawing 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. It consists of a cover sheet having a width narrower than the body, and a chip-shaped electronic component stored in a storage part formed by the cover sheet and a through hole, and the chip-shaped electronic component stored in the storage part is stored in the storage part. A chip-shaped electronic device characterized in that the cover sheet to be peeled off when taken out from the tape-shaped body is attached to the tape-shaped body in a straight line along the longitudinal direction of the tape-shaped body on both sides of the tape-shaped body in the width direction. This is a parts storage area.

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. In this way, the positional relationship and dimensional accuracy between the through hole 11 and the feed hole 12 will be 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. Such a tape-like body 1
A thin film-like cover sheet 13 is attached to one plane of 0. This cover sheet 13 constitutes one cover of the through hole 11, but does not exist in the area where the feed hole 12 is formed, and is
A tape-shaped body 10 having a width narrower than that of the tape-shaped body 10 is used so as not to cover the tape-shaped body 2 . 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 cover sheet 13 does not have to be attached to the entire surface, and it is sufficient to cover the through hole 11.
For example, only the width direction both sides of the tape-shaped body 10,
It may be attached linearly along the longitudinal direction of the tape-like body 10 using heat sealing or adhesive. 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 easily deformed by external force applied when storing and removing electronic components, and the shape of the storage section is easily deformed. It is preferable to attach it to the entire surface so that the electronic parts cannot be stored and taken out properly.

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.
The tape-shaped body 1 is not present in the region where the spout 2 is formed, and the tape-like body 1 is
A width narrower than the width of 0 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 possible to stick it in a straight line along the longitudinal direction of the tape-like body 10 only on both sides of the tape-like body 10 in the width direction, without sticking it on the entire surface of the tape-like body 10. is necessary. 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-like body 10 is sequentially fed out by adapting the feed hole 12 provided in the tape-like 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, since the cover sheet 14 is adhered only to both sides of the tape-like body 10 in the width direction, the adhesion force is approximately uniform over the entire length, and the peeling mechanism in an automatic machine is simplified. In addition, 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. That is, if the cover sheet 14 is adhered to the tape-like body 10 over the entire surface, there will be a difference in the adhesion strength 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 force 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 peeling off the cover sheet 14, and the electronic component 2 is taken out and 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 using the suction chuck or the like,
Even if some downward pressing force is applied to the bottom part, it 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. However, in consideration of the workability for adhesion, it is more convenient to also adhere the cover sheet 13 constituting the bottom portion in a straight line.

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 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.
Further, a feed hole 22 is 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. Also in this embodiment, the attachment of the cover sheet 14 on the side to be peeled off later is as follows:
It is sufficient if this is done on both sides of the tape-like body 20 in the width direction, but if necessary, the through-holes 21a, 2
It may also be applied to the tape-shaped body between 1b.

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, at least one of the cover sheets, that is, the side that is torn off when taking out the stored electronic components, is not attached to the tape-like body over its entire surface, but at least the width of the tape-like body is If the tape is applied in a straight line along the longitudinal direction on both sides of the sheet, the adhesion force of the sheet will be almost uniform over the entire length, and the peeling mechanism in an automatic machine will be can be done easily. Furthermore, since the adhesion force of this cover sheet is almost uniform over its entire length, unnecessary vibrations are not applied to the tape-like body when it is peeled off, so electronic components do not pop out from the storage compartment opened when it is peeled off. Stable operation is possible without any problems. For these reasons, the storage belt of the present invention can accurately supply chip-shaped electronic components during automatic mounting, so
~3 times faster and more reliable mounting is possible. In addition, with this invention, the number of stored electronic components can be determined by the length of the storage band.
Furthermore, this invention has the advantage of being able to prevent deterioration and damage of electronic components all the way up to the time of mounting, making it a highly effective invention.
