[Effect of invention]

According to the present invention, it is possible to provide an electronic component storage container and an electronic component group that can be adapted to automatically open and smoothly take out electronic components.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. In addition, in the embodiments shown below, the same or common parts are given the same symbols in the drawings, and the description thereof is not repeated.

(Embodiment 1) With reference to FIGS. 1 to 3, an electronic component group 100 according to an embodiment will be described.

As shown in FIGS. 1 to 3, the electronic component group 100 according to the first embodiment includes a plurality of electronic components 1 (see FIG. 2) and an electronic component storage container 10. The electronic component group 100 is configured to be able to take out the electronic component 1 stored in the storage recess 22 by slidingly moving the cover 40 relative to the main body 20 as described later.

The electronic component 1 is, for example, a multilayer ceramic capacitor. The length dimension, width dimension, and thickness dimension of the outer shape of the electronic component 1 are, for example, 1.0 mm×0.5 mm×0.5 mm, 0.4 mm×0.2 mm×0.2 mm, or 0.2 mm×0.1 mm×0.1 mm .

The electronic component storage container 10 includes a body portion 20, a cover sheet 30, and a cover portion 40. The electronic component storage container 10 has, for example, a longitudinal direction (DR1 direction) and a width direction (DR2 direction), and is formed in a long shape. In addition, the longitudinal direction is parallel to the sliding direction described later. In a plan view, the body portion 20, the cover sheet 30, and the cover portion 40 have a rectangular shape.

The body portion 20 is provided to extend in the above-mentioned longitudinal direction. The body portion 20 includes a flat plate portion 21, a plurality of storage recesses 22, and a plurality of raised portions 23. The body portion 20 is configured by processing a sheet member, for example. As the material of the sheet member, polystyrene, polyethylene terephthalate, etc., which are mixed with conductive materials such as carbon or conductive paint, can be used. The thickness of the sheet member is, for example, about 0.5 mm.

The flat plate portion 21 has a front surface 21a and a back surface 21b. The flat plate portion 21 is provided substantially parallel to the opening surface 224 of the storage recess 22 described later.

The plurality of storage recesses 22 are arranged side by side in the longitudinal direction DR1. The plurality of storage recesses 22 are arranged in a row, but it is not limited to this, and may be arranged in two rows, or may be arranged in two or more rows. In addition, the plurality of storage recesses 22 may be arranged in rows and columns, may be arranged in a dislocated state, or may be randomly arranged.

The storage recess 22 is configured to store a plurality of electronic components 1. If the external dimension of the electronic component 1 is 1.0 mm×0.5 mm×0.5 mm, more than 2000 electronic components 1 can be stored in one storage recess 22, for example, about 6000 electronic components 1 can be stored. If the external dimension of the electronic component 1 is 0.4 mm×0.2 mm×0.2 mm, about 100,000 electronic components 1 can be stored in one storage recess 22.

The storage recess 22 is provided to open toward one side. The storage recess 22 is provided to open toward the front surface 21 a side of the flat plate portion 21. The depth dimension of the storage recess 22 in the depth direction (AR1 direction) is greater than the thickness of the flat plate portion 21. The depth dimension of the storage recess 22 is, for example, about 12 mm.

The storage recess 22 includes a bottom 221 and a peripheral wall 222, and an opening 223 is formed at a position facing the bottom 221. The bottom 221 is provided substantially parallel to the flat plate portion 21. The peripheral wall portion 222 is erected from the peripheral edge of the bottom portion 221. An opening portion 223 is provided on the end side of the peripheral wall portion 222 connected to the flat plate portion 21.

The storage recess 22 is made of resin, and the surface resistivity of the inner surface of the storage recess 22 is preferably, for example, 0 Ω/□ or more and 1E09 Ω/□ or less. With this, it is possible to suppress the electronic component 1 from being attached to the inner surface of the housing recess 22 due to static electricity.

The opening portion 223 has a shape that does not include a side portion that extends in a direction orthogonal to the relative sliding direction (the AR2 direction in FIG. 4) of the lid portion 40 described later in a plan view. That is, the opening 223 has a shape in which the shape of the outer edge does not include a linear side portion extending in a direction orthogonal to the longitudinal direction. Specifically, the opening 223 has a substantially circular shape with a diameter of about 20 mm in plan view, for example.

In addition, the opening portion 223 may have an elliptical shape in a plan view, or may have a polygonal shape that does not include linear side portions extending in a direction orthogonal to the relative sliding direction of the cover portion 40. For example, the opening 223 may have a diamond shape in which a pair of vertices are arranged in the longitudinal direction (DR1 direction) and another pair of vertices are arranged in the width direction (DR2 direction) in a plan view.

The opening portion 223 has such a shape, and when the cover portion 40 is relatively slidably moved relative to the body portion 20, the joining area of the cover sheet 30 and the body portion 20 located around the opening portion 223 is peeled along The direction changes gently. With this, it is possible to prevent a large force from acting on the joint portion 33 momentarily when the cover sheet 30 is peeled off, so that the cover sheet 30 is broken or the cover sheet 30 cannot be peeled off.

The raised portion 23 is provided at the opening end of the opening portion 223. The raised portion 23 may be provided on the body portion 20 located at a portion around the storage recess 22. The bulging portion 23 bulges toward the side opposite to the depth direction of the storage recess 22.

The raised portion 23 is provided to surround the opening 223. The raised portion 23 has substantially the same shape as the peripheral portion of the predetermined opening 223 in a plan view. The opening edge of the storage recess 22 adjacent to the opening 223 has a curved portion. The raised portion 23 has a curved portion on the opening 223 side so as to be curved in the depth direction of the storage recess 22 as it faces the bottom 221 of the storage recess 22. The radius of curvature R of the curved portion is preferably 0.1 mm or more and 0.7 mm or less. By having such a bent portion, it is possible to prevent the plurality of electronic components 1 from getting caught on the bulging portion 23 when the plurality of electronic components 1 are taken out from the storage recess 22.

The height of the raised portion 23 is 0.5 mm or more and 1.2 mm or less. By setting the height of the raised portion 23 as described above, it is possible to suppress the electronic component 1 and the like from being caught between the cover portion 40 and the flat plate portion 21. In addition, the width of the raised portion 23 is approximately 1 mm or more and 2 mm or less. By setting the raised portion 23 to the aforementioned width, the force required when peeling the cover sheet 30 from the raised portion 23 can be reduced. Thereby, the deformation of the cover portion 40 and the main body portion 20 can be suppressed, and the cover sheet 30 can be stably peeled from the raised portion 23.

The cover sheet 30 has a band shape. In the longitudinal direction (DR2 direction), the length of the cover sheet 30 is longer than the length of the cover 40. Preferably, the length of the cover sheet 30 is more than twice the length of the body portion 20.

The cover sheet 30 is wound around the cover 40 and held. Specifically, the cover sheet 30 is wound around the cover portion 40 with the width direction (DR2 direction) as the winding axis. As a result, the cover sheet 30 includes the portion 31 located on the front side 40 a side of the cover 40 and the portion 32 located on the back side 40 b side of the cover 40.

One end 30a and the other end 30b of the cover sheet 30 are connected by the adhesive tape 50. In addition, one end 30a of the cover sheet 30 extends from the one end side (left side in FIG. 3) of the cover 40 toward the other end side (right side in FIG. 3) of the cover 40 on the front side 40a side of the cover 40 Ends. The other end 30b of the cover sheet is the end of the cover sheet 30 extending from the other end side (right side in FIG. 3) of the cover 40 toward one end side (left side in FIG. 3) of the cover 40 on the front side 40a side of the cover 40 . The one end 30a side of the cover sheet 30 and the other end 30b side are connected in a state of overlapping.

The cover sheet 30 is wound around the lid portion 40 after being joined to each of the plurality of raised portions 23 as described later. After that, both ends of the cover sheet 30 are connected. As long as both ends of the cover sheet 30 are connected, the connection method is not limited to the connection with the adhesive tape as described above.

The cover sheet 30 is wound around the cover 40 so as to surround the cover 40 in conjunction with the relative sliding movement of the cover 40. The cover sheet 30 rotates around the cover portion 40 as shown in the DR3 direction in FIG. 4 when the cover portion 40 relatively slides in the sliding direction (AR2 direction in FIG. 4 ).

The cover sheet 30 is provided to cover the plurality of openings 223. The cover sheet 30 has a joining portion 33 that is joined to at least a part of the body portion 20 of a portion around each of the plurality of openings 223. The cover sheet 30 is releasably joined to at least a part of the body portion 20.

The cover sheet 30 is preferably peeled when a force of 0.05 N or more and 5.00 N or less is applied to the joint 33.

The cover sheet 30 is made of, for example, a material having thermal fusion properties, and is bonded to each of the plurality of ridges 23 by thermal fusion. When the electronic component 1 is taken out from the storage recess 22, in order to prevent the electronic component 1 from adhering to the peeled portion of the cover sheet 30, it is preferable that the adhesiveness of the cover sheet 30 and the bump 23 of the joint portion 33 is small.

In addition, the cover sheet 30 may be bonded to each of the plurality of raised portions 23 by an adhesive. The cover sheet 30 is preferably transparent, but may be opaque.

When the plurality of electronic components 1 are sealed in the storage recess 22 using the cover sheet 30 to manufacture the electronic component group 100, the cover sheet 30 is joined to the body portion 20. When the cover sheet 30 is joined to the plurality of raised portions 23, the following operations are repeated in order from one side to the other side in the longitudinal direction, that is, after the plurality of electronic components 1 are stored in one storage recess 22, the cover is covered The sheet 30 is joined to the raised portion 23 of the portion corresponding to the one storage recess 22, and secondly, after storing a plurality of electronic components 1 in the storage recess 22 located in the partition wall thereof, the cover sheet 30 is joined to the corresponding recess 22 Part of the raised portion 23. In addition, after storing the plurality of electronic components 1 in each of the plurality of storage recesses 22 and covering the plurality of storage recesses 22 with the cover sheet 30, the cover sheet 30 may be thermally welded to be joined to the plurality of raised portions 23. When the plurality of storage recesses 22 are covered by the cover sheet 30, the cover sheet 30 is arranged on the body portion 20 in the longitudinal direction so that the cover sheet 30 is exposed from both ends in the longitudinal direction. Next, the cover sheet 30 is cut to a specific length. The specific length is the length by which the cover sheet 30 can be wound around the cover 40. Then, the cover portion 40 is arranged so as to sandwich the cover sheet 30 on the body portion 20 with the body portion 20. Next, as described above, the cover sheets 30 exposed from both ends of the body portion 20 are wound around the cover portion 40, and both ends of the cover sheet 30 are joined to each other. In this manner, the plurality of electronic components 1 are sealed in the plurality of storage recesses 22, and the electronic component group 1 is manufactured.

As a material constituting the cover sheet 30, for example, polyethylene terephthalate, polycarbonate, acrylic, vinyl chloride, or the like can be used. In addition, a metal coating may be applied to the cover sheet 30.

The surface resistivity of the cover sheet 30 is preferably 1E11 Ω/□ or less. This can prevent the electronic component 1 from adhering to the surface of the cover sheet 30 due to static electricity.

The cover portion 40 is arranged so as to sandwich a part of the cover sheet 30 with the body portion 20 (more specifically, the raised portion 23). The surface of the cover portion 40 facing the body portion 20 is not connected to the cover sheet 30. In addition, the so-called disconnection means that they are not fixed or joined.

The cover 40 includes a plate-shaped portion 41 and a guide 42. The plate-like portion 41 extends in the longitudinal direction (DR1 direction). The plate-like portion 41 is provided substantially parallel to the flat plate portion 21. The cover sheet 30 is wound around the plate-like portion 41.

The guide portion 42 is provided at both ends of the plate-shaped portion 41 in the width direction (DR2 direction).

The guide portion 42 prevents the cover portion 40 from falling off from the body portion 20 and guides the sliding movement of the cover portion 40. Specifically, the guide portion 42 is arranged on the flat plate portion 21 with a gap such that the flat plate portion 21 is located between a portion facing the front surface 21a of the flat plate portion 21 and a portion facing the back surface 21b of the flat plate portion 21 Ends.

In addition, the shape of the guide portion 42 can be suitably changed as long as the cover portion 40 can be slidably moved relative to the body portion 20.

As the material constituting the cover portion 40, resin may be used. The resin member may be transparent or opaque. When the cover portion 40 and the cover sheet 30 are made transparent, it can be visually confirmed that a plurality of electronic components 1 are stored in the storage recess 22.

In the longitudinal direction, the length of the cover portion 40 is longer than the length of the body portion 20. In the longitudinal direction, the length of the cover portion 40 is less than half of the length of the cover sheet 30.

4 is a diagram showing a state in which the cover part of the electronic component group of the embodiment is relatively slidably moved relative to the body part. FIG. 5 is a cross-sectional view showing an electronic component taken out of the electronic component group of the embodiment. In addition, in FIG. 4, for convenience of explanation, the state in which the electronic component group 100 is arranged with the opening 223 of the storage recess 22 facing upward is shown. However, when the electronic component 1 is taken out, it is stored as shown in FIG. 5. In a state where the electronic component group 100 is arranged with the opening 223 of the recess 22 facing downward, the cover 40 is relatively slidably moved relative to the body 20. 4 and 5, a description will be given of how the electronic component 1 is taken out from the electronic component group 100 of the embodiment.

As shown in FIGS. 4 and 5, in order to take out the plurality of electronic components 1 stored in the storage recess 22, the cover 40 is relatively slidably moved in the sliding direction (AR2 direction) relative to the body 20. Specifically, the cover portion 40 is fixed by a fixing device (not shown) and the body portion 20 is slid in a direction opposite to the AR2 direction (AR3 direction). The main body 20 is moved by a certain amount by a conveying device (not shown). The conveying device may be, for example, a conveyor type that mounts and moves the main body 20, or may be configured to hold and move the main body 20.

When the lid portion 40 relatively moves in the sliding direction (AR2 direction), first, the peeling force acts on the engaging portion 33 located behind the relative sliding direction of the lid portion 40. Furthermore, by the relative sliding movement of the cover portion 40, the cover sheet 30 is gradually peeled off in the relative sliding direction of the cover portion 40.

At this time, the relative sliding movement of the cover sheet 30 and the cover 40 rotates around the cover 40 as shown in the DR3 direction. Specifically, it rotates around the winding axis in such a manner that, behind the relative sliding direction of the cover 40, the portion 32 located on the back 40b side of the cover 40 moves toward the front 40a of the cover 40 Before the relative sliding direction of the cover 40, the portion 31 on the front 40a side of the cover 40 moves toward the back 40b of the cover 40.

When focusing on one storage recess 22, the storage recess 22 is unsealed by peeling the cover sheet 30 from one end side of the cover portion 40 in the relative sliding direction to the other end side from the periphery of the opening 223 (swelled portion 23). By opening the storage recess 22, a plurality of electronic components 1 fall downward from the opening 223 and are supplied toward the supplied part.

At this time, the inner circumferential surface of the storage recess 22 is smoothly formed without grooves or the like. As a result, it is possible to prevent the plurality of electronic components 1 from catching on the inner circumferential surface of the storage recess 22, and the plurality of electronic components 1 can be smoothly taken out from the electronic component storage container 10.

The cover portion 40 is relatively slidably moved in the AR2 direction from the one end 20a side of the body portion 20 toward the other end 20b side, and the cover sheet 30 is gradually peeled from the ridge portion 23 from the one end 20a side of the body portion 20 toward the other end 20b side. Thus, the storage recesses 22 are sequentially opened. Thereby, a plurality of electronic components 1 are sequentially taken out from the unsealed storage recess 22. In addition, the relative sliding movement of the cover 40 may be performed continuously or intermittently.

As described above, in the electronic component storage container 10 and the electronic component group 100 of this embodiment, a plurality of electronic components 1 can be smoothly taken out.

In addition, since the surface of the cover portion 40 facing the body portion 20 is not joined to the cover sheet 30, when the cover portion 40 is relatively slidably moved relative to the body portion 20, the cover portion 40 can be smoothly moved. In addition, the cover sheet 30 can also move relative to the cover portion 40, and the cover sheet 30 can be easily peeled off from the body portion 20.

In addition, by holding the cover piece 30 with the cover portion 40 and sliding the cover portion 40 relative to the body portion 20, the storage recess 22 can be automatically opened using the fixing device and the conveying device. Thereby, a plurality of electronic components 1 can be automatically supplied to the supplied part.

In addition, by configuring the cover 40 to hold the cover sheet 30 and sliding the cover 40 relative to the main body 20 in a direction parallel to the opening surface 224, the cover can be suppressed when the cover sheet 30 peels off The portion 40 and the body portion 20 are deformed.
