Description

The present invention relates to an embossed tape that houses parts and the like of electrical equipment.

Conventionally, an embossed tape (embossed carrier tape) for accommodating parts of electrical equipment has been used. In the present application, parts and the like of electrical equipment housed in the embossed tape may be referred to as "accommodation objects". Generally, the embossed tape has a plurality of pockets (embossed) that can accommodate the object to be accommodated, and by attaching the cover tape while the object to be accommodated is accommodated, the relevant parts, etc. are contained in each pocket. Can be sealed. By using such embossed tape, even small parts can be safely and conveniently stored and transported.

FIG. 16 is an external view of a part of the embossed tape 101 according to the conventional example. Further, FIG. 17 is a schematic arrow view of the FF cross section of the embossed tape 101 shown in FIG. In the embossed tape 101, a plurality of pocket portions 112 are arranged side by side on a seat portion 111 extending long in the front-rear direction, and it is possible to accommodate an object to be accommodated in each pocket portion 112.

The embossed tape 101 is formed by subjecting a heated sheet material to a press drawing process for providing a recess. Of the sheet material, the recessed portion formed by the press drawing process becomes the pocket portion 112, and the remaining portion remains as the sheet portion 111.

Since the pocket portion 112 is formed by press drawing, as shown in FIG. 17, a roundness (R shape) is formed in the corner portion 112c located at the boundary between the bottom surface 112a and the side surface 112b of the pocket portion 112. Will be done. Further, as the conventional carrier tape, for example, the one disclosed in Patent Document 1 can be mentioned. This carrier tape is provided with a cushioning mechanism in a pocket formed on the embossed tape so as to absorb a drop impact or the like.

The object to be stored in the embossed tape is taken out from the pocket portion and used by using a suction nozzle or the like, for example, in the manufacturing process of electrical equipment. It is very important that the object to be stored can be easily taken out from the pocket portion in order to ensure the quality of the manufacturing process and the like.

In view of this point, if the close contact area between the object to be stored in the pocket portion and the bottom surface or the side surface of the pocket portion is wide, the following problems are likely to occur. First, the object to be stored in the embossed tape may have oil or the like attached to it. For example, when a pre-plated metal press-molded product is an object to be stored, press oil is often attached to the object to be stored.

When such an object to be stored is housed in the pocket portion of the embossed tape and the object to be stored and the bottom surface or the side surface of the pocket portion are in close contact with each other in a wide range, the press oil does not dry at that location and the object to be stored and the press oil are pressed. (Chemical reaction, etc.) may occur, and the solderability (easiness of soldering) of the contained object may deteriorate. In addition, the press oil may not dry and the stored object may be stuck to the bottom surface or the side surface of the pocket portion, making it difficult to remove the stored object from the pocket portion.

Further, for example, in the case of the embossed tape 101 described above, the R-shaped portion of the corner portion 112c has a shape that gradually advances upward from the end of the bottom surface 112a. Therefore, as shown in FIG. 18, the end portion of the accommodation object OB rides on the corner portion 112c, and the accommodation object OB tends to tilt. If such an inclination occurs, there is a possibility that the suction of the storage object OB to the suction pad may be hindered when the storage object OB is taken out from the pocket portion 112 by using the suction pad (vacuum pad). Therefore, it may be difficult to remove the stored object from the pocket portion.

Further, when a storage object having protrusions such as burrs is housed in the pocket portion, the protrusion may be caught in the pocket portion and the storage object may be tilted (see FIG. 24 and the like). In this case as well, it may be difficult to remove the stored object from the pocket portion.

In view of the above-mentioned problems, an object of the present invention is to provide an embossed tape that makes it possible to easily take out an object to be stored from a pocket portion. In other words, it is an object of the present invention to provide an embossed tape capable of providing an avoidance means for avoiding close contact with the outer surface of the stored object or tilted storage of the stored object and facilitating the removal of the stored object from the pocket portion. ..

The embodiments of the present invention will be described below with reference to the respective drawings, taking each of the first to fourth embodiments as an example.

1. 1. First Embodiment First, the first embodiment will be described. The vertical, horizontal, and front-back directions (directions orthogonal to each other) in the following description are as shown in FIG. The front-rear direction corresponds to the extending direction of the embossed tape 1 described later, and the left-right direction corresponds to the width direction of the embossed tape 1. Further, the upward direction coincides with the opening direction of the pocket portion 12 described later.

FIG. 1 is a partial configuration diagram of an embossed tape (embossed carrier tape) 1 according to the present embodiment. 2 is an arrow view of the AA cross section of the embossed tape 1 shown in FIG. 1, and FIG. 3 is an arrow view of the BB cross section of the embossed tape 1 shown in FIG. Further, FIG. 4 is a partial configuration diagram of the embossed tape 1 in a state where the storage object OB (for example, a small contact mounted on a portable communication device) is housed. It is assumed that the overall shape of the object to be accommodated here is a rectangular parallelepiped shape. The lower outer surface (lower surface) of the storage object OB is flat, and when the storage object OB is stored in the pocket portion 12, the outer surface is parallel to the bottom surface 12a of the pocket portion 12.

As shown in each of the above figures, the embossed tape 1 has a seat portion 11, a pocket portion 12, a left side support protrusion 13a, and a right side support protrusion 13b. In the embossed tape 1, a plurality of pocket portions 12 are arranged in the front and rear at equal intervals on the seat portion 11 extending long in the front and rear, and the storage object OB can be accommodated in each pocket portion 12.

The embossed tape 1 is formed by subjecting a heated sheet material to a press drawing process for providing a recess. The sheet material is made of a material such as plastic that softens by heating, and is made of, for example, PS (polystyrene), PET (polyethylene terephthalate), or PP (polypropylene). Of the sheet material, the recessed portion formed by the press drawing process becomes the pocket portion 12, and the remaining portion remains as the sheet portion 11.

The seat portion 11 is a sheet-shaped (tape-shaped) portion that extends long in the front-rear direction with the left and right sides in the width direction, and is fed out from the reel on one end side (position that does not interfere with the pocket portion 12) in the left-right direction of the seat portion 11. A plurality of feed holes 11a used for the above are provided at equal intervals in the front-rear direction. A cover tape (not shown) can be attached to the upper surface of the sheet portion 11 so as to seal each pocket portion 12 by, for example, a heat sealing method.

The pocket portion 12 is a pocket-shaped portion in which a space for accommodating an object to be accommodated is formed. The lower side of the space faces the bottom surface 12a (partly a support protrusion), and the front, rear, left and right sides are It faces the side surface 12b. The bottom surface 12a of the pocket portion 12 is parallel to the upper surface of the seat portion 11 and is formed so as to spread forward, backward, left and right. The angle between the bottom surface 12a and the front, rear, left, and right side surfaces 12b is 90 degrees or slightly larger than this.

The upper part of the pocket portion 12 is opened, and the stored object OB can be stored and taken out through this opening. The spatial shape of the pocket portion 12 is a substantially rectangular parallelepiped shape with the front and back in the lateral direction and the left and right in the longitudinal direction. Further, the space size of the pocket portion 12 is set to be slightly larger than the storage object OB so that the storage object OB can be easily stored and taken out. The distance between the left and right side surfaces 12b is about 3 to 4 mm, and the distance between the front and rear side surfaces 12b is about 1 to 2 mm.

Since the pocket portion 12 is formed by press drawing, as shown in FIGS. 2 and 3, the corner portion 12c located at the boundary between the bottom surface 12a and the side surface 12b of the pocket portion 12 has a surface R. The shape (roundness) is formed. The radius of curvature of the R shape is about 0.1 mm. The vertical position β of the upper end of the R-shaped portion is as shown in FIGS. 2 and 3. The R shape at the corner portion 12c is a shape that gradually advances upward from the end of the bottom surface 12a to the position β in the vertical direction. The R shape is not formed at the position above the vertical position β, and the inclination of the surface of the pocket portion 12 is constant.

The left side support protrusion 13a and the right side support protrusion 13b are formed at the same time as the pocket portion 12 by the press drawing process described above, and are provided so as to project upward from the bottom surface 12a of the pocket portion 12. The tip portions (upper end portions) of these support protrusions 13a and 13b support the storage object OB housed in the pocket portion 12 upward. Further, the support protrusions 13a and 13b are arranged so as to be symmetrical with respect to the plane that bisects the pocket portion 12 to the left and right, and can support the accommodation object OB in a well-balanced manner.

By storing and packaging the object to be stored OB in the embossed tape 1, it is possible to safely and conveniently store and transport the object to be stored OB. In this storage / packaging process, for example, the embossed tape 1 wound on the reel is unwound in order from the end, and the storage object OB is stored in the pocket portion 12. After that, the cover tape is fixed to the surface of the sheet portion 11, so that the object to be accommodated is sealed in the pocket portion 12.

When using the stored object OB stored and packaged in the embossed tape 1, the cover tape fixed to the embossed tape 1 is removed from the surface of the sheet portion 11 to expose the stored object OB. Just take it out. This removal can be realized, for example, by sucking the upper surface portion of the object to be accommodated OB on a suction pad (vacuum pad) and moving the suction pad as it is.

Next, the shapes and features of the support protrusions 13a and 13b will be described in more detail.

The left side support protrusion 13a is provided at a position on the left side of the bottom surface 12 so that both ends extend back and forth until the vicinity of the front and rear side walls 12b of the pocket portion 12. On the other hand, the right side support protrusion 13b is provided at a position on the right side of the bottom surface 12 so that both ends extend back and forth until the vicinity of the front and rear side walls 12b of the pocket portion 12. The surfaces of the support protrusions 13a and 13b have substantially the same shape as a part of the surface of the cylinder extending back and forth.

Therefore, as shown in FIG. 2, in a cross section cut by a plane whose normal direction is the front-back direction, the upper surfaces of the support protrusions 13a and 13b are arcs exposed on the upper side (a form of a curve that is convex on the upper side). It has the shape of. Further, as shown in FIG. 3, in a cross section cut by a plane having a normal direction in the left-right direction, the surfaces of the support protrusions 13a and 13b are straight lines extending back and forth. It can be said that the tips of the support protrusions 13a and 13b each have a convex curved surface shape.

In this way, as shown in FIGS. 5 to 7, the tip portions of the support protrusions 13a and 13b are in line contact with the lower outer surface (the plane whose normal direction is the vertical direction) of the accommodation object OB. It is said that the shape is. Here, FIG. 5 is an arrow view of the CC cross section of the embossed tape 1 shown in FIG. 4, and FIG. 6 is an arrow view of the DD cross section of the embossed tape 1 shown in FIG. Further, FIG. 7 is an enlarged view of the region P shown by the dotted line frame in FIG.

As shown in these figures, the left support protrusion 13a is in line contact with the corresponding outer surface of the object to be accommodated OB at the line segment La extending in the front-rear direction, and the right support protrusion 13b is in the line segment Lb extending in the front-rear direction. Line segment contact with the corresponding outer surface of the object to be accommodated OB. The storage object OB housed in the pocket portion 12 is supported upward only by line contact with the support protrusions 13a and 13b, and does not touch the bottom surface 12a. The support protrusions 13a and 13b are arranged in the pocket portion 12 in a well-balanced manner, and can stably support the accommodation object OB. Assuming that the tips of the support protrusions 13a and 13b are not deformed, the line contact with the housed object OB is almost perfect, but in reality, the tips are slightly deformed by the load received from the housed object OB. Therefore, line contact in the strict sense may not be maintained. "Line contact" in the present application is a concept including such a situation.

Since the tips of the support protrusions 13a and 13b are in line contact with the corresponding outer surface of the storage object OB, the storage object OB housed in the pocket portion 12 and the bottom surface side of the pocket portion 12 are in close contact with each other. The area can be made as small as possible. Therefore, even if the press oil adheres to the storage object OB, the press oil easily dries between the storage object OB and the bottom surface side of the pocket portion 12. As a result, it is possible to suppress the chemical reaction between the contained object OB and the press oil, and to prevent the situation in which the solderability (easiness of soldering) of the contained object OB deteriorates as much as possible. Furthermore, it is possible to prevent as much as possible a situation in which the stored object OB sticks to the bottom surface of the pocket portion 12 without the press oil drying, making it difficult to remove the stored object OB from the inside of the pocket portion 12.

Further, as shown in FIGS. 2 and 3, the vertical position α of the tip portions of the support protrusions 13a and 13b is above the vertical position β of the upper end of the R-shaped portion formed in the corner portion 12c. There is. In the present embodiment, the distance between the bottom surface 12a and the position α is about 0.2 mm, and the distance between the bottom surface 12a and the position β is about 0.1 mm. As a result, as shown in FIGS. 5 and 6, the lower surface of the storage object OB housed in the pocket portion 12 is located above the R-shaped portion.

Therefore, as illustrated in FIG. 18, it is possible to prevent the end portion of the accommodation object OB from riding on the corner portion and prevent the accommodation object OB from tilting in the pocket portion 12. .. As a result, when the storage object OB is taken out from the pocket portion 12 by using the suction pad (vacuum pad), the upper outer surface of the storage target OB is horizontal, and the storage target OB is sucked onto the suction pad. Can be performed more reliably. Even if the tip of the support protrusion provided on the bottom surface 12a does not make line contact or point contact with the corresponding outer surface, the purpose of preventing the end of the accommodation object OB from riding on the corner is achieved. Can be done.

FIG. 8 is an external view of the contact OB1 which is a specific example of the accommodation object OB, and FIG. 9 is an external view of the contact OB1 viewed from another angle. The contact OB1 is formed by bending a single metal plate material, and includes a bottom portion OB11, a contact portion OB12 connected to the bottom portion OB11 via a leaf spring, and a housing portion OB13 that covers and protects the leaf spring. , Have. The contact portion OB12 is formed so as to be urged upward by a leaf spring when pushed downward by the object to be connected. As a result, the connection target soldered to the lower surface (planar) of the bottom OB 11 can be stably and electrically connected to the connection target. When the contact OB1 is housed in the pocket portion 12, the portion shown by the broken line in FIG. 9 is in line contact with the tip portions of the support protrusions 13a and 13b.

2. Second Embodiment Next, the second embodiment of the present invention will be described. The second embodiment is basically the same as the first embodiment except for the morphology of the support protrusions. In the description of the second embodiment, emphasis is placed on the description of the parts different from those of the first embodiment, and the description of the parts common to the first embodiment may be omitted.

FIG. 10 is an external perspective view of a part (pocket portion 12) of the embossed tape 2 according to the second embodiment. Further, FIG. 11 is an external perspective view of a part (pocket portion 12) of the embossed tape 10 in a state where the accommodation object OB is accommodated.

As shown in FIG. 10, in the embossed tape 2 of the second embodiment, six support protrusions (13c to 13h) are provided instead of the support protrusions 13a and 13b of the first embodiment. These support protrusions 13c to 13h are provided so as to project upward from the bottom surface 12a of the pocket portion 12. The tip (upper end) of each of the support protrusions 13c to 13h supports the corresponding outer surface of the storage object OB housed in the pocket portion 12 upward.

The first support protrusion 13c is provided on the left side of the bottom surface 12 at a position centered in the front-rear direction. The second support protrusion 13d is provided on the right side of the bottom surface 12 and at the center position in the front-rear direction. The third support protrusion 13e and the fifth support protrusion 13g are provided so as to be arranged in the front-rear direction at a position slightly to the left of the bottom surface 12 (on the right side of the first support protrusion 13c). The fourth support protrusion 13f and the sixth support protrusion 13h are provided so as to be arranged in the front-rear direction at a position slightly to the right of the bottom surface 12 (on the left side of the second support protrusion 13d). Further, the first support protrusion 13c and the second support protrusion 13d, the third support protrusion 13e and the fourth support protrusion 13f, and the fifth support protrusion 13g and the sixth support protrusion 13h each have the pocket portion 12 bisected to the left and right. It is arranged so as to be symmetrical with respect to the plane to be divided, and it is possible to support the accommodation object OB in a well-balanced manner.

The surface of each of the support protrusions 13c to 13h has substantially the same shape as a part of the surface of the sphere. Therefore, the upper surface of each of the support protrusions 13c to 13h is an arc exposed on the upper side (upper side) in a cross section cut by an arbitrary plane passing through the front end of the support protrusion (however, a plane whose normal direction is orthogonal to the vertical direction). It has a shape of a convex curve). It can be said that the tips of the support protrusions 13c to 13h each have a convex curved surface shape.

In this way, each of the support protrusions 13c to 13h has a shape in which the tip end portion is in point contact with the corresponding outer surface (a plane whose normal direction is the vertical direction) under the accommodation object OB. Here, FIG. 12 is an arrow view of an EE cross section of the embossed tape 2 shown in FIG. In this figure, it is shown that the first to fourth support protrusions 13c to 13f are in point contact with the object to be accommodated OB.

The surface shapes of the first and second support protrusions 13c and 13d are slightly larger than those of the third to sixth support protrusions 13e to 13h, and the amount of protrusion from the bottom surface 12a is slightly larger. ing. In this way, the shapes and dimensions of the support protrusions 13c to 13h are adjusted so that all of the support protrusions 13c to 13h come into point contact with the lower outer surface of the object to be accommodated OB.

Each of the support protrusions 13c to 13h makes point contact with the object to be accommodated OB at the tip portion (central portion when viewed upward). The storage object OB housed in the pocket portion 12 is supported upward only by point contact with each of the support protrusions 13c to 13h, and does not touch the bottom surface 12a. The support protrusions 13c to 13h are arranged in the pocket portion 12 in a well-balanced manner, and can stably support the accommodation object OB. Assuming that the tips of the support protrusions 13c to 13h are not deformed, the point contact is almost perfect with respect to the accommodation object OB, but in reality, the tips are slightly deformed by the load received from the accommodation object OB. Therefore, point contact in the strict sense may not be maintained. "Point contact" in the present application is a concept including such a situation.

Since the tips of the support protrusions 13c to 13h make point contact with the corresponding outer surface of the storage object OB, the storage object OB housed in the pocket portion 12 and the bottom surface side of the pocket portion 12 are in close contact with each other. The area can be made as small as possible. Therefore, as in the case of the first embodiment, it is possible to prevent as much as possible a situation in which the solderability of the storage object OB deteriorates and a situation in which the storage object OB becomes difficult to take out from the pocket portion 12.

Further, also in the second embodiment, as in the case of the first embodiment, the vertical position of the tip portion of each of the support protrusions 13c to 13h is from the vertical position of the upper end of the R-shaped portion formed in the corner portion 12c. Is also on the upper side. Therefore, as illustrated in FIG. 18, it is possible to prevent the end portion of the accommodation object OB from riding on the corner portion and prevent the accommodation object OB from tilting in the pocket portion 12. ..

3. 3. Third Embodiment Next, a third embodiment of the present invention will be described. The third embodiment is basically the same as the first embodiment except for the support protrusions. In the description of the third embodiment, emphasis is placed on the description of the parts different from those of the first embodiment, and the description of the parts common to the first embodiment may be omitted.

The fourth lateral support protrusion 14d is provided at a position closer to the upper side and to the right side on the rear side surface 12b. The fifth lateral support protrusion 14e is provided at a position closer to the upper side and to the left side on the front side surface 12b. The sixth lateral support projection 14f is provided at a position closer to the upper side and to the left side on the rear side surface 12b. The first side support protrusion 14a and the second side support protrusion 14b face each other in the left-right direction, the third side support protrusion 14c and the fourth side support protrusion 14d face each other in the front-rear direction, and the fifth side support protrusion 14b faces each other. The 14e and the sixth lateral support projection 14f face each other in the front-rear direction. When the storage object OB is arranged exactly in the center of the pocket portion 12, a slight gap is formed between the storage object OB and the lateral support protrusions 14a to 14f.

In this way, the lateral support protrusions 14a to 14f are arranged in a well-balanced manner on the front, rear, left, and right side surfaces 12 surrounding the space of the pocket portion 12, and can support the accommodation object OB inward, front, back, left, and right. Is. As a result, the stored object OB does not come into contact with any of the front, rear, left, and right side surfaces 12b, and is maintained closer to the center of the space of the pocket portion 12 by upward viewing.

Further, the tips of the lateral support protrusions 14a to 14f are in line contact (contact with a line extending up and down) with the corresponding outer surface of the object to be accommodated OB, similarly to the support protrusions 13a and 13b of the first embodiment. The object to be accommodated OB is supported in the projecting direction of the lateral support protrusions 14a to 14f. The tip portions of the lateral support protrusions 14a to 14f have a convex curved surface shape, similarly to the support protrusions 13a and 13b of the first embodiment.

Since the tips of the lateral support protrusions 14a to 14f are in line contact with the corresponding outer surface of the storage object OB, the storage object OB housed in the pocket portion 12 and the entire side surface of the pocket portion 12 It is possible to make the close contact area between them as small as possible. Therefore, even if the press oil adheres to the storage object OB, the press oil easily dries between the storage object OB and the side surface of the pocket portion 12. As a result, it is possible to suppress the chemical reaction between the contained object OB and the press oil and prevent the situation in which the solderability of the contained object OB deteriorates as much as possible. Furthermore, it is possible to prevent as much as possible a situation in which the stored object OB is stuck to the side surface of the pocket portion 12 without the press oil drying, making it difficult to remove the stored object OB from the inside of the pocket portion 12.

Further, the tip portions of the lateral support protrusions 14a to 14f are located closer to the protrusion direction than the R-shaped portion formed in the corner portion 12c. For example, focusing on the third side support protrusion 14c in FIG. 15, the front and rear of the rear end of the R-shaped portion formed in the corner portion 12c corresponding to the front side surface 12b (the side surface 12b provided with the side support protrusion 14c). The anteroposterior position γ of the tip of the third lateral support projection 14c is behind the directional position δ. That is, the tip portion of the third side support protrusion 14c is located closer to the rear (closer to the protrusion direction of the third side support protrusion 14c) than the R-shaped portion formed in the corner portion 12c.

Therefore, by suppressing the accommodation object OB from approaching the R-shaped portion, it is possible to prevent the end portion of the accommodation object OB from riding on the corner portion as illustrated in FIG. 18, and the accommodation object OB is prevented. Can be prevented from tilting in the pocket portion 12. As a result, when the storage object OB is taken out from the inside of the pocket portion 12 by using the suction pad, the upper outer surface of the storage target OB is horizontal, and the suction of the storage object OB to the suction pad is more reliable. It becomes possible to do. The tips of all or part of the lateral support protrusions 14a to 14f may be formed so as to make point contact with the corresponding outer surface of the object to be accommodated OB. Another purpose is to prevent the end of the object to be accommodated OB from riding on the corner even if the tip of the lateral support protrusion provided on the side surface 12b does not make line contact or point contact with the corresponding outer surface. Can be achieved.

4. Fourth Embodiment Next, the fourth embodiment of the present invention will be described. The fourth embodiment is basically the same as the first embodiment except that a recess is provided in place of the support protrusion to avoid contact with a burr (one form of the protrusion). In the description of the fourth embodiment, emphasis is placed on the description of the parts different from the first embodiment, and the description of the parts common to the first embodiment may be omitted.

The embossed tape 4 according to the fourth embodiment accommodates a contact (accommodation target) OB2 in which burrs occur at a predetermined location, and a recess 41 for avoiding contact with burrs generated in the contact OB2 is a pocket portion. 12 is provided (see FIG. 26). First, the contact OB2 housed in the embossed tape 4 will be described.

FIG. 19 is an external perspective view of the intermediate product MP generated in the manufacturing process of the contact OB2, and FIG. 20 is an external view of the intermediate product MP from an upward viewpoint. The intermediate product MP is formed by bending a single metal plate material, and is in a state in which a plurality of main parts MP1 and carrier parts MP2, which later become contact OB2, are connected. When the intermediate product MP is cut along the line L shown by the broken line in FIG. 20 in the above manufacturing process, it is separated into a plurality of main parts MP1 and a carrier part MP2, and each main part MP1 is obtained as a contact OB2.

The basic configuration and function of the contact OB2 are the same as those of the contact OB1 in the first embodiment. As shown in FIG. 23, the contact OB2 has a bottom portion OB21, a contact portion OB22 connected to the bottom portion OB21 via a leaf spring, and a housing portion OB23 that covers and protects the leaf spring. The contact portion OB22 is formed so as to be urged upward by a leaf spring when pushed downward by the object to be connected. As a result, the connection target soldered to the lower surface (planar) of the bottom OB 21 can be stably and electrically connected to the connection target.

FIG. 21 schematically shows a step of cutting the intermediate product MP on the line L. As shown in this figure, in the process, the fixed blade C1 is set on the upper side of the carrier portion MP2 and the moving blade C2 is set on the lower side of the main portion MP1, and the intermediate product MP is generated by moving the moving blade C2 upward. Be disconnected. The upper surface of the carrier portion MP2 in contact with the fixed blade C1 and the lower surface of the main portion MP1 in contact with the moving blade C2 form substantially the same plane except for the deviation of the thickness of the metal plate material. Cutting using (C1, C2) is easy. If such a blade is set on the upper side of the main portion MP1, the contact portion OB22 or the housing portion OB23 may hit the blade and be deformed or damaged. Therefore, in order to avoid such a problem, it is necessary to set the blade on the lower side of the main portion MP1 as in the present embodiment.

However, when the intermediate product MP is cut in the form shown in FIG. 21, burrs (carrier cut burrs) that protrude substantially downward at the cut portion, that is, the portion indicated by α in this figure (the left end portion of the bottom portion 21). ) Occurs. FIG. 22 shows a photograph of the burr BR generated in this way. If the contact OB2 that has generated the burr BR is accommodated in the pocket portion of a general embossed tape, the burr BR may be caught in the pocket portion and the contact OB2 may not be accommodated in the embossed tape at the correct position.

FIG. 23 shows how the contact OB2 is housed in the pocket portion of the general embossed tape 400 at the correct position, and FIG. 24 shows the burr BR of the contact OB2 caught on the bottom surface of the pocket portion and the contact OB2 is tilted. It shows that it was contained in a state (in an incorrect position). Note that FIGS. 23 and 24 (the same applies to FIGS. 25 to 27 described later) are views from the same viewpoint as in FIG. In both FIGS. 23 and 24, after the contact OB2 is housed in the pocket portion, it is sealed using the cover tape CT. However, in the state shown in FIG. 24, the contact OB2 is placed at a position slightly to the right of the pocket portion, and the right end portion abuts on the right side surface of the pocket portion, so that the contact OB2 is tilted. Even in this state, if the lower part of the contact OB2 slides on the bottom surface of the pocket portion, the inclination is eliminated, but the contact OB2 can slide on the bottom surface because the burr BR bites into the bottom surface a little. However, the contact OB2 remains tilted. In particular, the burrs generated by the cutting process as described above often have sharper tips than the protrusions intentionally provided as part of the product, and as described above, they bite into the bottom surface (the surface of the pocket portion). Easy to put away.

If the contact OB2 is tilted in this way, there arises a problem that the contact OB2 cannot be properly attracted to the suction nozzle (the nozzle for vacuum sucking and transporting parts and the like at the tip). FIG. 25 schematically shows how the defect occurs when the upper surface of the housing portion OB23 of the contact OB2 is to be sucked by the suction nozzle. If the contact OB2 is tilted as shown in this figure, a gap is formed between the end surface of the suction nozzle C3 and the contact OB2 (housing portion 23), which hinders vacuum suction. When the suction nozzle C3 is brought close to the contact OB2 from above, when the suction nozzle C3 comes into contact with the contact OB2, the contact OB2 is pushed down while the burr BR bites into the pocket portion, and the contact OB2 is on the right side surface and the bottom surface of the pocket portion ( There is a possibility that the contact OB2 will be more difficult to be taken out from the pocket portion due to a situation in which the contact OB2 is strongly pinched by the portion where the burr BR bites.

In order to solve the above-mentioned problems, the embossed tape 4 according to the present embodiment is provided with a recess 41 as shown in FIG. 26. The recess 41 is provided at the left end portion (the portion corresponding to the burr BR) on the bottom surface of the contact OB2 so that the burr BR of the contact OB2 can be prevented from coming into contact with the bottom surface of the pocket portion 12. The left side and front and rear walls of the recess 41 are formed so as to coincide with the left side and front and rear side surfaces of the pocket portion 12. As a result, while providing a recess in the pocket portion 12 to avoid contact with the burr BR, the corner portion generated in the pocket portion 12 is reduced to simplify the shape, and the pocket portion 12 including the recess 41 is provided. It is said that press drawing is as easy as possible.

In the example of the present embodiment, the depth d1 of the pocket portion 12 is set to about 1.3 mm, while the depth d2 of the recess 41 is set to about 0.1 mm. Due to the provision of such a recess 41, even if the contact OB2 is tilted as shown in FIG. 27, the burr BR does not bite into the bottom surface of the pocket portion 12, and the contact OB2 is on the bottom surface. It slips and is stored in the correct position.

The shape and dimensions of the recess 41 are set so that the burr BR does not come into contact with the bottom surface even when the contact OB 2 moves in the pocket portion 12 as shown in FIG. 27. That is, the contact OB2 sealed in the pocket portion 12 may move in the area surrounded by the side surface and the bottom surface of the pocket portion 12 and the cover tape CT due to an impact or the like. Even if it moves in this way, the burr BR fits in the recess 41 and the burr BR does not come into contact with the bottom surface. As a result, even if the contact OB2 sealed in the pocket portion 12 moves and becomes tilted once, it slides on the bottom surface to eliminate the tilt and returns to the state of being housed in the correct position.

5. Summary As described above, the embossed tapes 1 to 3 according to the first to third embodiments have a pocket portion 12 in which the storage object OB is housed, and the bottom surface 12a or the side surface 12b of the pocket portion 12 has a pocket portion 12. A support protrusion is provided so that the tip portion in the protruding direction supports the corresponding outer surface of the object to be accommodated OB. Further, the tip portion has a shape that makes point contact or line contact with the corresponding outer surface of the object to be accommodated OB. Therefore, it is possible to make it easier to reduce the close contact region between the storage object OB housed in the pocket portion 12 and the bottom surface 12a or the side surface 12b of the pocket portion 12.

In general, the outer surface of parts and the like of electrical equipment that can be an object to be accommodated is often flat, and the support protrusions according to each embodiment support such an object to be accommodated by point contact or line contact. It is a suitable shape for. In the first or second embodiment, since the stored object OB is supported upward only by point contact or line contact with the support protrusion, the contact area between the stored object OB and the bottom surface of the pocket portion 12 is the minimum. It can be suppressed to the limit.

The upper ends of the support projections 13a and 13b according to the first embodiment have a shape that makes line contact with the accommodation object OB, and the upper ends of the support projections 13c to 13h according to the second embodiment are the accommodation objects. It has a shape that makes point contact with the OB. The shape of the support protrusion when viewed upward can be in various forms. For example, as shown in FIG. 13, the shape of the support protrusion 13x when viewed upward is a shape that orbits slightly inside the outer circumference of the bottom surface 12a, and the upper end of the support protrusion 13x is in line contact with the object to be accommodated OB. May be. Further, as shown in FIG. 14, four support protrusions 13p to 13s that are circular in the upward view are arranged near the four corners of the bottom surface 12a, and the upper ends of the support protrusions 13p to 13s are in point contact with the object to be accommodated OB. The shape may be.

Even if the support projection whose upper end is in line contact with the accommodation object OB and the support projection whose upper end is in point contact with the accommodation object OB coexist in the same pocket portion 12. good. Further, as the shape of the upper end of the support protrusion, various shapes can be adopted within the range of point contact or line contact with the object to be accommodated.

Further, the tip end portion of the support protrusion according to each embodiment is formed in a convex curved surface shape that is convex in the protrusion direction of the support protrusion. By forming the support protrusion in such a shape, it is easy to secure the strength of the tip portion and suppress unnecessary deformation in the vicinity of the tip portion as compared with the case where the upper end is sharpened, for example. Further, for example, even if there is some variation (inclination) in the orientation of the corresponding outer surface, the position slightly deviated from the apex of the tip portion of the support protrusion contacts the corresponding outer surface, and it is easy to appropriately secure point contact or line contact. It becomes. As an example, even if the corresponding outer surface is tilted as shown by the broken line in FIG. 7, a position slightly deviated from the apex of the tip of the support protrusion 13a (the position of the line segment La) makes line contact with the corresponding outer surface.

The tip of the support protrusion (the protruding direction is defined as "direction D") having the above-mentioned convex curved shape is in the direction of the line of the line contact when the line contact is made with the corresponding outer surface of the object to be accommodated. When the outer edge shape seen is curved in the direction D and makes point contact with the corresponding outer surface of the object to be accommodated, the outer edge shape seen in an arbitrary direction orthogonal to the direction D is convex in the direction D. It has a curved shape. In particular, in each of the first to third embodiments, the "convex curved shape" has an arc shape so that the contact form between the two does not change as much as possible even if the corresponding outer surface is slightly tilted.

Further, the tip end portion of the support protrusion according to the first or second embodiment is closer to the protrusion direction (here, than the R-shaped portion formed at the corner portion 12c (the boundary between the bottom surface 12a and the side surface 12b) of the pocket portion 12). Located on the upper side). Therefore, it is possible to prevent the end portion of the accommodation object OB from riding on the corner portion 12c and to prevent the accommodation object OB from tilting in the pocket portion 12.

Further, the tip of the lateral support protrusion according to the third embodiment is closer to the protrusion direction (for example, the first) than the R-shaped portion formed at the corner portion 12c (the boundary between the bottom surface 12a and the side surface 12b) of the pocket portion 12. In the case of the lateral support protrusion 14a, it is located to the right). Therefore, it is possible to prevent the end portion of the accommodation object OB from riding on the corner portion 12c and to prevent the accommodation object OB from tilting in the pocket portion 12.

The pocket portion 12 may be provided with support protrusions on both the bottom surface 12a and the side surface 12b. For example, in the same pocket portion 12, the bottom surface 12a may be provided with the support protrusions according to the first or second embodiment, and the side surface 12b may be provided with the side support protrusions according to the third embodiment. As a result, it is possible to easily reduce the close contact region between the lower surface and the lateral outer surface of the storage object OB and the inner surface of the pocket portion 12.

Further, the support protrusions (or side support protrusions) of each embodiment are considered to support the corresponding outer surface upward (or laterally orthogonal to the vertical direction) until the accommodation object OB does not contact the corner portion 12c. You can also do it. The arrangement and protrusion length of each support protrusion (or lateral support protrusion) are set according to the outer surface shape of the storage object OB so as to support the storage object OB at a position where it does not contact the corner portion 12c. Is desirable.

Further, the embossed tape 4 according to the fourth embodiment has a pocket portion 12 in which the contact OB2 (accommodation object) is accommodated, and a predetermined portion (lower left end portion) of the contact OB2 is provided on the bottom surface of the pocket portion 12. A recess 41 is provided to avoid contact with the burr BR that occurs in the above. As a result, the burr BR can be prevented from being caught in the pocket portion 12, the inclination of the contact OB2 can be suppressed, and the contact OB2 can be easily taken out from the pocket portion 12. The position of providing such a recess may be determined according to the position of the burr generated in the object to be accommodated. If the burr generated on the object to be stored is in a position where it comes into contact with the side surface of the pocket portion, a recess may be provided on the side surface of the pocket portion accordingly. Further, in the present embodiment, a recess is provided to avoid contact with the burr BR, but for example, a recess may be provided to avoid a protrusion intentionally provided as a part of the object to be accommodated. Can suppress the protrusion from being caught in the pocket portion.

In addition to the above embodiments, the configuration of the present invention can be modified in various ways without departing from the gist of the invention. That is, it should be considered that the above embodiment is an example in all respects and is not restrictive. The technical scope of the present invention is shown not by the description of the above embodiment but by the scope of claims, and it is understood that the meaning equivalent to the scope of claims and all modifications belonging to the scope are included. Should be.

The present invention can be used, for example, as an embossed tape for accommodating parts of electrical equipment and the like.
