【Example】

(Embodiment 1) Embodiment 1 of the present invention, a resin tape having a plurality of depressions for accommodating components, will be described with reference to FIGS. A resin tape (hereinafter, referred to as a resin tape) 1 having a plurality of recesses for accommodating the components shown in FIG. 1 is made of PET (polyethylene terephthalate) and is a long flat portion 2.
And a plurality of recesses 3 which are provided at equal intervals in the longitudinal direction P of the plane portion 2 and are rectangular as viewed from the plane side (upward side in FIG. 1), and the opening 30 from the one surface 20 side of the plane portion 2. And a protruding portion 4 protruding from the portion.

The width W and the thickness t of the flat portion 2 are variously set and set according to the shape and size of the components to be accommodated in the recess 3. As shown in FIG. 1 showing a plane and FIG. 2 showing a cross section thereof, the recess 3 is formed such that the one surface 20 side of the flat portion 2 is elongated in the width W direction, is rectangular, and is recessed to a predetermined depth L, and the other surface 21 is formed. It protrudes in a rectangular shape toward the side. Depression 3
An opening 30 and four sides forming the opening 30, that is,
From the long sides 31, 32 and the short sides 33, 34, the peripheral wall portions 310, 320 (see FIG. 3) and the peripheral wall portions 330, 340 hang down in the vertical direction, respectively, and the peripheral wall portions 310, 320 and the peripheral wall portions 330, 340. And a bottom 35 provided.

The projecting portion 4 partially narrows the opening 30 of the recess 3 and projects in a substantially triangular shape from the side 20 of the flat portion 2 toward the opening 30 of the recess 3. Of the long sides 31, 32 and short sides 33, 34 to be formed, the long side 3
There are a total of four provided so as to face each other at two locations 1 and 32 via the opening 30. In the resin tape 1 configured as described above, the component 5 to be housed is inserted into the recess 3 through the opening 30 as shown in FIG.

At this time, since the peripheral wall portions 310 and 320 are forcibly pushed open through the projecting portion 4 and elastically deformed in the expanding direction when the component 5 is inserted, the opening portion 30 Even if there is, the component 5 can be passed through and housed in the recess 3. Once the component 5 housed in the recess 3 returns to its original position due to the elastic reaction force generated when the peripheral wall portions 310 and 320 elastically deform, the projecting portion 4 that narrows the opening portion 30 is accordingly formed. Since it functions as a stopper, it is held in a housed state (see FIG. 3).

The resin tape 1 in a state in which the component 5 is accommodated and held in the recess 3 in this manner is wound in a predetermined amount in a roll shape, and then wound on a production line of an electronic device, an electronic device, and an automobile. And used to supply it to the assembly process site. That is, the components 5 housed in the plurality of depressions 3 of the resin tape 1 are taken out by the device installed at the site of the assembling process, and assembled at the assembly target location.

As described above, according to the resin tape 1 of the first embodiment, (1) the component 5 housed in the recess 3 protrudes from the surface 20 side of the plane 2 of the resin tape 1 toward the opening 30, Opening 30
It can be held by the protruding portion 4 that narrows the portion. For this reason, as in the prior art, a configuration for holding the state in which the component 5 is accommodated in the recess is used, without using a lid material for heat welding or bonding to close the opening 30 of the recess 3 on the surface 20 of the plane 2. As a result, the number of parts can be reduced, and a conventional two-part part can be used. (2) Further, prior to taking out the component 5 from each recess 3 of the resin tape 1 in the assembling step of the production line, the cover material is peeled off from the surface 20 of the flat surface 2 on the opening 30 side of each recess 3. No process is required. Therefore, the number of steps can be reduced, and the cost of the steps can be improved. (3) Since a lid material is not used for the opening 30 of each depression 3, the component 5 held in each depression 3 can be easily taken out, and the work of taking out the component 5 becomes simple. (4) When the parts 5 housed in the respective recesses 3 of the resin tape 1 are taken out, unlike the case using a lid material which is heat-sealed or bonded to the surface 20 of the flat surface 2 on the opening 30 side of the respective recesses 3 Unlike the conventional configuration, there is no breakage or deformation of one surface 20 of the flat surface 2 of the resin tape 1 caused by forcibly peeling off the lid material.

For this reason, the resin tape 1 from which the components 5 housed in the recesses 3 are taken out can be used repeatedly many times without being discarded, and the material cost can be greatly reduced. As shown in FIG. 2, the projecting portions 4 are formed at two places on the long side 31 of the recess 3 and at one place on the long side 32 facing the intermediate position between the two places. There can be a total of three. In this case, substantially the same effect as in the first embodiment can be obtained. Further, the shape of the protrusion 4 is not limited to the above-described substantially triangular shape, and FIG.
5 and FIG.
The same effect as that of the first embodiment can be obtained by using the substantially semicircular projection 4b shown as the second modification.

(Embodiment 2) A resin tape having a plurality of depressions for accommodating the components of Embodiment 2 (hereinafter referred to as a resin tape)
1A will be described with reference to FIG. The resin tape 1A shown in FIG. 6 has a peripheral wall portion 310 on the long side 31 side and a peripheral wall portion 320 on the long side 32 side instead of the protrusion 4 of the first embodiment.
The configuration is the same as that of the resin tape 1 of the first embodiment except that a protruding portion 4a that protrudes toward the dent 3 from the side and narrows the portion of the dent 3 (opening 30) is formed.

The resin tape 1A has one surface 2
0 (the opening 30 of the depression 3), the projection 4a protruding from the peripheral wall portions 310 and 320 of the depression 3 has the effect of the first embodiment and the depth of the projection 4 of the first embodiment. The depth L1 (see FIG. 6) from the protruding portion 4a to the bottom 35 of the depression 3 is smaller than the height L (see FIG. 1) and the same,
The component 5 of the first embodiment, even if it is of a shape and size
The effect that a thing with a smaller diameter can be held is obtained.

Further, the device for forming the projecting portion 4a requires only a slight setup change for a part of the production line of the resin tape 1 provided with the device for forming the projecting portion 4 of the first embodiment. Most of the other components have the advantage that they can be shared without changing the setup. (Embodiment 3) A resin tape (hereinafter, referred to as a resin tape) 1B having a plurality of depressions for accommodating the components of Embodiment 3 is shown in FIG.
A description will be given based on FIG.

The resin tape 1B shown in FIG. 7 has a parallel portion 2 at a predetermined distance in the longitudinal direction P perpendicular to the long sides 31 and 32 of the recesses 3 of the resin tape 1,
The configuration is the same as that of the resin tape 1 of the first embodiment, except that a plurality of cutout portions 61 and 62 are formed as relief portions for releasing deformation accompanying expansion of the opening 3. The cutouts 61 and 62 have a long hole shape with a predetermined width W1 and a predetermined length L2.

According to the resin tape 1B of the third embodiment, in addition to the effect of the resin tape 1 of the first embodiment, a plurality of cutouts are formed on the outer periphery of the depression 3 as relief portions for releasing deformation accompanying expansion of the opening 30. It has notches 61 and 62. For this reason, when the component 5 is gripped by the gripping portion of the robot (not shown, the same applies hereinafter) and the accommodating operation and the taking-out operation in the dent 3 are performed, the opening 30 is formed by an amount corresponding to the insertion of the gripping portion into the dent 3. The distortion generated by expanding in both side regions S1 and S2 (see FIG. 8) of the component 5 quickly escapes to the cutouts 61 and 62.

Therefore, according to the resin tape 1B of the third embodiment, a so-called automatic operation in which the component 5 is gripped by the gripping portion of the robot and the operation of housing and taking out the cavity 3 can be smoothly performed. And man-hours can be reduced.

【The invention's effect】

(1) According to the resin tape having a plurality of depressions for accommodating the component according to the first aspect, the component accommodated in each depression projects toward the opening from the negative surface side of the resin tape or the peripheral wall portion of the depression.
The opening can be held by a projection that narrows at least the opening. For this reason, as in the conventional case, as a configuration for holding the state in which the component is housed in the recess, there is no need to use a lid material that is heat-sealed or adhered to one surface of the opening side of the recess, so that the component forming the resin tape is used. The number of points may be one, and the number of conventional two-part parts can be reduced. (2) Further, there is no need for a step of peeling and removing the lid material from one surface of the opening side of each dent before taking out a part from each dent of the resin tape in the assembly step of the production line.
Therefore, the number of steps can be reduced, and the cost of the steps can be improved. (3) Since the lid material is not used for the opening of the dent, the components held in the dent can be easily taken out and the taking-out work can be simplified. (4) Unlike the case where a lid material that is heat-sealed or bonded to one surface of the opening side of the dent is used, when taking out a part housed in the dent of the resin tape, as in the conventional configuration, the lid material of the resin tape is used. There is no tearing deformation on one side of the resin tape caused by forcibly peeling off.

For this reason, the resin tape from which the components accommodated in the recess have been taken out can be used many times without discarding, and the material cost can be greatly reduced. (5) According to the resin tape having a plurality of recesses for accommodating the component of claim 2, in addition to the effect of the resin tape having a plurality of recesses for accommodating the component of claim 1, the outer periphery of the recess has
Because there is an escape part to escape the deformation accompanying the expansion of the opening,
When a part is gripped by the gripping part of the robot and the accommodating operation and the taking-out operation are performed in the dent, the distortion caused by the dent being forcibly expanded to the outer peripheral side by the insertion of the gripping part into the dent is promptly reduced. The above operations can be smoothly performed by the escape and the grip portion.

[0029] Therefore, since the operation can be performed by the robot operation, the operation can be performed unmanned and the man-hour can be reduced.
