Abstract

PURPOSE:To retain the positional accuracy of a part receiving body by forming engaging holes independently of an inserting hole and a gap between one of the engaging parts engageable with the engaging holes and its respective engaging hole to permit their mutual movement in the longitudinal direction. CONSTITUTION:Engaging holes 8 and 9 are formed independently of an inserting hole and engaging parts 10 and 11 are provided for engagement with the engaging holes 8 and 9, respectively. A gap is formed between the engaging part 11 and its respective engaging hole 9 to permit their mutual movement in the longitudinal direction. In this structure wherein a package 4 using synthetic resin is mounted in a carrier tape 3 to be carried thereon, even if the package 4 is shrunk due to a drop in ambient temperature from the high to the normal, since the engaging part 11 is movable relative to the engaging hole 9, the carrier tape 3 is not affected adversely, i.e., there is no occurrence of its deflection. In case the package should shrink, moreover, its shrinkage takes place relative to the other engaging hole 8, thereby retaining the positional accuracy of a part receiving body 1.

[0004] The package 55 has a flange portion 56 projecting outward, and stop portions 58 formed through the stop portion extraction holes 57 formed on the carrier tape 53 side and at the four corners, so that the carrier tape 53 can be held in place. It is firmly fixed by pinching it.

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 to prevent the component from falling off, and the carrier tape 53 is It is supplied to a predetermined component mounting portion through feed holes 53a formed on both side edges.

[0006]

[Problems to be Solved by the Invention] However, the above conventional configuration has the following problems. That is,
The joint between the carrier tape 53 and the package 55 by composite molding (the stopper hole 57 of the carrier tape 53 and the stopper 5 of the package 55 formed through the stopper hole 57)
8) is completely fixed, as shown in FIG. 11, when the temperature drops from the high temperature during composite molding to room temperature and the package 55 contracts due to the shrinkage rate inherent to the resin, the carrier tape 53 There was a problem in that the package 55 could not cope with the shrinkage and was bent.

[0007]

[Means for Solving the Problems] In order to solve the above-mentioned problems, the parts storage body of the present invention is provided in which a package having a storage recess for storing parts is placed on a flexible tape-shaped carrier material at a predetermined interval. The parts storage body is inserted into an insertion hole formed in the package, and a stop part formed on the package side is engaged with a lock hole provided at the front and rear edges of the insertion hole of the conveyed material. , each of the locking holes is formed independently with respect to the insertion hole, and a locking part that is engaged with the locking hole and the locking hole are provided so as to be movable in the front and rear directions relative to each other. A gap is formed between the two.

[0008]

[Function] According to the above structure, even when the package shrinks due to a drop in temperature from high temperature to room temperature when, for example, composite molding of a package using synthetic resin is performed on a conveyor, one stop part is engaged. Since it can be moved relative to the fixed hole, it does not cause any adverse effects or bending on the carrier tape.
Furthermore, when the package is contracted, the package is contracted with reference to the other locking hole, so the positional accuracy of the component storage body is maintained.

[0009]

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. 1 to 8. 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 package for storing parts fixed in each insertion hole 2 (made of hard synthetic resin)
It is composed of 4. The package 4 includes a package main body 6 having a storage recess 5 for storing components, a flange portion 7 projecting outward from the upper end of the package main body 6, and a flange portion 7 provided in each insertion hole 2 of the carrier tape 3. A fixed side stop hole (locking hole) 8 and a movable side stop hole (
It consists of locking portions 10 and 11 that are formed by passing through a locking hole (locking hole) 9. Further, the fixed side stopper extraction hole 8 and the movable side stopper extraction hole 9 are provided at symmetrical positions with respect to each other, and are each formed independently of the insertion hole 2.

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. 3, 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,
Concave portions 22c and 22d for forming the stop portions 10 and 11, respectively, are formed at positions corresponding to the stop portions 9, and a gap for movability is formed by protruding to the side of the movable side stop portion extraction hole 9 (see Fig. 2). A protrusion 22b is formed to form a.

Therefore, by injecting, for example, synthetic resin into the upper and lower molds 21 and 22, the package 4 having the storage recess 5 in which parts can be stored as described above can be integrally injection molded onto the carrier tape 3. will be done.

Furthermore, as shown in FIG. 3, 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 the shrinkage rate decreases and shrinks due to the resin's inherent shrinkage rate, 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. 4 and 5. 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, and therefore, this fixed side stopperehole 8 serves 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 at the center of each of the fixed side stopper extraction hole 8 and the movable side stopper extraction hole 9, as shown in FIGS. 4 and 6, 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.

The operation of feeding mechanical parts by the parts feeding device 31 as shown in FIG. 7 will be described using the parts storage body 1 constructed as described above. The parts storage body 1 is stored wound on a supply reel 32, and includes a wheel 33, a ratchet 34, a lever 35, and a link 3.
6, the predetermined pitch P is
It is rolled out. Immediately before passing through the wheel 33, the cover tape 25 for holding the components (not shown) stored in the component storage body 1 so that they do not fly out is peeled off by the cover collection reel 37. be able to take it out. After taking out the parts, immediately after passing the wheel 33, the parts storage body 1 is wound around the wheel 33 by a guide roller 38 so as not to wrap too much around the wheel 33, as shown in FIG. and location is regulated. 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, it passes through another guide roller 39 and is wound onto the collection reel 40 of the parts storage body 1. In this way, each stopper hole is provided independently of the insertion hole of the package, and one of the stoppers can be moved relative to the stopperehole, so that it is possible to prevent the package from falling off and to prevent the package from falling off. Even when shrinking, the positional accuracy of the package can be maintained. Note that, for example, if one stopper hole is provided integrally with the insertion hole, it is possible to prevent the carrier tape from bending in response to shrinkage of the package. When force is applied in the torsional direction, the package and carrier tape separate because there is no restriction on the degree of freedom of the central part of the package in the integrally provided stopper hole.

[0019]

As described above, according to the structure of the present invention, even when the package shrinks due to a drop in temperature from high temperature to room temperature when, for example, synthetic resin is used to compositely mold a package onto a carrier, Since one stop can move relative to the lock hole, it does not cause any adverse effects or flexing on the carrier tape. Furthermore, when the package contracts, it contracts with respect to the other lock hole, so the parts The positional accuracy of the storage body can be maintained.
