BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a parts storage body for storing electronic parts and mechanical parts.

0002

2. Description of the Related Art Conventionally, parts storage bodies for storing electronic parts and mechanical parts have already been proposed as shown in FIGS. 13 and 14.

This component storage body 51 consists of a carrier tape 5 in which a large number of rectangular insertion holes 52 are formed at predetermined intervals.
3, and a package 55 which is inserted and fixed into each insertion hole 52 of this carrier tape 53 and has a recess 54 for storing parts.

The package 55 is firmly held by sandwiching the carrier tape 53 between a flange portion 56 projecting outward and a stop portion 58 formed through a stop hole 57 formed on the side of the carrier tape 53. Fixed.

The package 55 is formed and fixed to the carrier tape 53 by integral composite molding using a mold. Further, in the component storage body 51, after the component is stored in the storage recess 54, the opening of the storage recess 54 is covered with a cover tape 59 to prevent the component from falling off, and the carrier tape 53 Feed holes 53a formed on both side edges of
It is supplied to a predetermined component mounting section via.

[0006]

[Problems to be Solved by the Invention] However, the above configuration has the following problems. ■Since only one part is stored in one package 55, it is necessary to form the same number of packages 55 as the number of parts to be stored. Therefore, it takes a lot of time to form the packages 55, which reduces efficiency. was bad.

[0007] When the size of the package 55 or the width of the carrier tape 53 is constant, and the components to be accommodated are elongated, a large amount of space is wasted.

[0008]

[Means for Solving the Problems] In order to solve the above-mentioned problems, the parts storage body of the present invention is such that a package having a storage recess for storing parts is placed at a predetermined interval on a flexible tape-like carrier material. This is a component storage body in which a plurality of parts are fixed to each other, and a plurality of sets of holding parts for holding parts are formed in the storage recess.

[0009]

According to the above structure, one package is provided with holding portions for a plurality of sets of parts, so the number of molded packages in the parts storage body is reduced to less than half, and molding time is saved. Furthermore, since the same type or different types of parts, that is, a plurality of parts, are housed in one package, the takt time for supplying parts can be shortened, and in turn, the tact time for the entire assembly operation can be shortened.

Embodiment An embodiment of the present invention will be described below with reference to FIGS. 1 to 12. In FIG. 1, reference numeral 1 denotes a parts storage body, which includes a synthetic resin carrier tape (carrying material) 3 in which a large number of rectangular insertion holes (see FIG. 2) 2 are formed at predetermined intervals, and A component storage package (made of hard synthetic resin) 4 fixed in each insertion hole 2
It is composed of. The package 4 includes a package body 6 having a storage recess 5 for storing components;
A flange portion 7 protruding outward from the upper end of the package body 6 and each insertion hole 2 of the carrier tape 3.
Stops 10 and 11 are formed by passing through the fixed side stop hole 8 and the movable side stop hole 9 formed in the front and rear positions of It is composed of a holding section 12 that can hold the device. Of course, a plurality of sets of the holding parts 12 are provided depending on the number and type of parts. The stationary side stopper hole 8 and the movable side stopperehole 9 are provided at symmetrical positions and are formed independently of the insertion hole 2, respectively.

Next, a method for integrally forming and fixing the package 4 to the carrier tape 3 will be explained. That is, as shown in FIG. 2, the lower mold 21 and the upper mold 22 are overlapped from above and below the carrier tape 3 at the position corresponding to the insertion hole 2.

Of course, the lower mold 21 is shaped to match the shape of the lower part of the package 4, and the upper mold 22 has a protrusion 22 for forming the recess 5 for storing the package 4.
a is provided, and fixed side and movable side stopper holes 8,
Recesses 22c and 22d for forming stoppers 10 and 11, respectively, are formed at positions corresponding to 9, and protrude into the sides of the movable side stopper hole 9 to create a movable gap (see FIG. 9). A protrusion 22b is formed to form a.

[0013] Also, the protrusion 22 of the upper mold 22
A recess (not shown) is also formed in a for forming a holding part 12 that can hold a plurality of parts at the same time. Therefore, by injecting, for example, synthetic resin into the upper and lower molds 21 and 22, the package 4 having the holding portion 12 capable of holding a plurality of parts at the same time as described above can be integrally injection molded onto the carrier tape 3. will be done.

Note that FIGS. 3 and 4 show a case in which a holder 12A for holding the same type of component H is formed, and FIGS.
A case is shown in which holders 12B and 12C for holding different types of parts I and J are formed.

Further, as shown in FIG. 2, the movable side stopper hole 9 is formed by a protrusion 22b provided on the upper mold 22 when the carrier tape 3 and the package 4 are compositely molded. The shrinkage side of the side stopper hole 9 is filled with the amount of resin shrinkage or a little more space, so when the mold is removed, there will be a space corresponding to the resin shrinkage, so the temperature will change from high temperature to room temperature. Even if it shrinks due to the shrinkage rate inherent to the resin, the movable side stopper hole 9 has a degree of freedom in the direction M of the fixed side stopper hole 8, as shown in FIGS. 8 and 9. Therefore, even if the resin package 4 contracts, the carrier tape 3 is not adversely affected, that is, the carrier tape 3 is not bent.

Furthermore, since the fixed side stopper hole 8 is an independent thin elongated hole, it is not affected by shrinkage. Therefore, this fixed side stoppere hole 8 is used as a reference, and is aligned with respect to the longitudinal direction of the carrier tape 3. Positional accuracy can be maintained without wobbling.

Furthermore, since stopper narrow grooves 8a and 9a are provided in the center of each of the fixed side stopper removal hole 8 and the movable side stopper extraction hole 9, as shown in FIGS. 8 and 10, the resin Even if the package 4 shrinks in the width direction N of the carrier tape 3, there is no adverse effect due to the shrinkage, and therefore the parts held in the storage recess 5 maintain their postures with high accuracy. Note that the stopper narrow grooves 8a and 9a are made sufficiently small.

Furthermore, since the package 4 is attached to the carrier tape 3 at a predetermined pitch, as shown in FIG. Feed holes 3a are formed at a predetermined pitch P, and a cover tape 25, which is narrower than the width of the carrier tape 3 and wider than the width of the insertion hole 2 of the package 4, is attached to prevent parts from falling off.

Using the component storage body 1 constructed as described above, the operation of supplying mechanical components by the component supply device 31 as shown in FIG. 11 will be explained. The component storage body 1 is stored in a wound state on a supply reel 32, and is fed out at a predetermined pitch P by a feed drive unit constituted by a wheel 33, a ratchet 34, a lever 35, and a link 36. Immediately before passing through the wheel 33, the cover collection reel 37
The cover tape 25 for holding the parts (not shown) housed in the housing so that they do not fly out is peeled off so that the parts can be taken out. Then, after removing the parts,
Immediately after the component storage body 1 passes the wheel 33, as shown in FIG. 12, the winding angle and position of the component storage body 1 are regulated by a guide roller 38 so as not to wrap around the wheel 33 too much. This prevents adjacent packages 4 of the component storage body 1 from interfering with each other and being damaged when the size of the components stored in the component storage body 1 increases and the pitch P increases.

After passing through the guide roller 38, the sheet passes through another guide roller 39 and is wound onto the collection reel 40 of the parts storage body 1.
