Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a spacer tape and a tab tape spacer capable of reliably preventing deformation of a tab tape.
[0002]
[Prior art]
Generally, the spacer tape is a projection projecting in the thickness direction on one or both of the front and back sides of both side edges in order to allow the tab tapes wound on the reel to be wound at appropriate intervals in the reel radial direction. It has.
[0003]
This projection is formed by deforming a part of the tape by embossing as described in, for example, JP-A-11-45914 or JP-A-7-285576, or disclosed in JP-B-8-19116. Or by injection molding.
[0004]
[Problems to be solved by the invention]
By the way, since the projections of these conventional products are arranged at appropriate intervals in the longitudinal direction of the tape, when they are wound around the reel together with the tab tape, the positions of the projections overlapping inside and outside are shifted in the longitudinal direction of the tape, and the projections on the inside are shifted. In some cases, the tab projections and the spacer tape may be deformed by the outer projections being fitted therebetween.
[0005]
In addition, the deformation of the tab tape and the spacer tape causes defective products due to damage to the electronic component package due to frictional contact between the electronic component and the spacer tape, deformation of the leads of the electronic component, and the like.
[0006]
Furthermore, the deformation of the leads of the electronic component and the plastic deformation of the tab tape cause a decrease in location accuracy and the generation of defective products in the component mounting process on the board due to the movement of the electronic component.
[0007]
In the spacer tape described in JP-A-11-45914, the width of the tapered pyramid-shaped spacer portion, that is, the protrusion in the tape longitudinal direction is considerably larger than the gap between the spacer portions adjacent in the tape longitudinal direction. Formed, thereby preventing the outer projection from fitting between the inner projections.
[0008]
However, even in this conventional device, the corners of the protrusions of the outer spacer tape may bite between the protrusions of the inner spacer tape to deform the spacer tape and the tab tape. In addition, in this case, the force acting on the tape at the corners of the projections is concentrated, and the spacer tape and the tab tape are plastically deformed. Therefore, the location accuracy of the electronic components in the process of mounting the electronic components on the board is reduced, and defective products are generated. Can not solve the problem of inviting.
[0009]
SUMMARY OF THE INVENTION It is an object of the present invention to solve the problems of the prior art and to provide a spacer tape capable of reliably preventing deformation of a tab tape.
[0010]
[Means for Solving the Problems]
In order to achieve the above object, the first spacer tape of the present invention (hereinafter referred to as the first tape of the present invention) is provided on one or both sides of the tape in the thickness direction on both sides of the tape body in the longitudinal direction. In a spacer tape having a protruding protrusion, a technical means is adopted in which the protrusion is formed continuously over the entire length of the tape body.
[0011]
According to this, since the protrusions are continuous over the entire length of the tape body, the inner and outer spaces of the tape body wound on the reel are accurately and uniformly maintained, and the tab tape or the spacer tape is locally deformed, that is, bent. The danger of occurrence of elimination is completely eliminated.
Hereinafter, the first tape of the present invention will be described in more detail.
[0012]
First, the tape body of the first tape of the present invention needs to have bending elasticity in the thickness direction in order to enable winding on a reel.
[0013]
Also, the material of the tape body is not particularly limited, and may be selected from known materials for the tape body of the spacer tape, such as synthetic resin, metal, animal fiber, plant fiber, and composite materials of two or more of these. Just fine.
[0014]
Furthermore, the shape of the tape body is not particularly limited as long as the tape shape is long in the longitudinal direction.For example, a tapered shape, a material having an opening for saving material and weight reduction including a ladder shape, A known shape such as a net shape may be adopted.
[0015]
Further, the method of forming the tape body is not particularly limited, and the tape body can be formed by a known resin molding method such as extrusion molding, injection molding, mold casting, and the like. A method of obtaining a tape roll by slicing the roll at appropriate intervals in the axial direction may be employed.
[0016]
The protrusion in the first tape of the present invention may be any projection as long as it protrudes in the thickness direction on one or both of the front and back sides of the tape main body at both longitudinal side edges of the tape main body. It is preferable that the tape is evenly projected on both front and back surfaces of the tape body so that the pressure and the tension acting on the tape body become zero or almost zero. In other words, it is preferable that the neutral axis in the thickness direction of the tape main body and the neutral axis in the tape thickness direction of the protrusion match when viewed from the tape width direction.
[0017]
When providing protrusions on the front and back surfaces of the tape body, it is not necessary to match the position of the protrusions in the tape width direction on both front and back surfaces.For example, the protrusions on the front surface are arranged at both ends of the entire width of the tape, and the protrusions on the back surface are It is possible to arrange the tape on the center side of the tape or one of the protrusions on the front side at one end of the entire width of the tape and the other on the inner side of the tape, and place one protrusion on the back side more than one protrusion on the front side. The other protrusion may be arranged at the other end of the entire width of the tape at the center of the tape.
[0018]
However, in order to reduce the overall width of the spacer tape and to reduce the height of the protrusion from the tape body to increase the bending elasticity in the thickness direction of the spacer tape, the position of the protrusion in the tape width direction is matched on both sides. Is preferred.
[0019]
The projections need to have bending elasticity in the cross-sectional direction like the tape main body, but the method of obtaining this bending elasticity is not particularly limited. For example, a method of selecting a material, a method of selecting a shape, and the like. There is a method of using these in combination, and the method of selecting a material is, for example, a method of forming a protruding portion with an elastic polymer composition such as rubber, and the method of selecting a shape is, for example, a method of forming a cross-sectional shape. This is a method of forming an open figure, forming a hollow shape, or forming a thin wall.
[0020]
In selecting the material of the projection, the material of the projection can be the same or different from that of the tape. If the same material is used, the tape body and the projection are extruded, injection-molded, and molded. In addition to being able to be formed simultaneously by any resin molding technique such as molding, tape-shaped materials can be simultaneously formed into thin tape bodies by thickening the protrusions, for example, by heating roll forming or cold roll forming, After the formation, the end of the tape main body can be formed by plastic working such as flanging, curling, roll forming, and multi-stage pressing, or by heat plastic working or heating die working.
[0021]
Here, the plastic working is a stress applied from the outside of the material, that is, a process of plastically deforming with external stress, and the heating plastic working is a process of plastically deforming the material with external stress while heating the material. Heating mold processing is to heat a material by applying it to a mold including rolls and rails, and to apply intermolecular tension, intermolecular repulsion, difference in intermolecular tension between heated and unheated surfaces, and between heated and unheated surfaces. This is the process of adjusting to the mold by internal stress such as intermolecular repulsion difference.
[0022]
When the material of the projection is made different from that of the tape body, the projection can be formed simultaneously with the molding of the tape body by, for example, simultaneous extrusion molding, simultaneous injection molding, sequential die casting, or the like.
[0023]
Of course, even if the material of the tape body and the projection is the same or different, the tape body and the projection are separately formed in advance, and the tape body and the projection are bonded, for example, by adhesion, fusion, welding, welding, crimping, It is also possible to join by a method such as fitting.
[0024]
Furthermore, the material different from the tape body includes a composite material, for example, a composite material obtained by combining a material different from the tape body with a synthetic resin of the same or different material as the tape body.
[0025]
Examples of the composite material include a composite material of a strand and a synthetic resin including a wire made of a synthetic resin, metal, or the like, or a single wire or a stranded wire made of a synthetic resin, metal, animal fiber, plant fiber, or the like. There is.
[0026]
Examples of the structure in which the strip and the synthetic resin are combined include, for example, an impregnated structure in which the strip is impregnated with the synthetic resin, a mold structure in which part or all of the strip is embedded in the synthetic resin, and a synthetic resin tube. There is an insertion structure in which a strip is inserted into the body.
[0027]
In addition, as the composite material, a large number of reinforcing materials having a predetermined height in the tape thickness direction are different from the reinforcing materials such that ends in the tape longitudinal direction overlap with each other when viewed from the tape width direction. There is a structure embedded in the synthetic resin strip. The material of the reinforcing material can be arbitrarily selected, for example, a metal, a synthetic resin of the same quality as or different from the tape body.
[0028]
The shape of the protrusion may be a shape protruding in one or both sides of the tape in the thickness direction of the tape, and the cross-sectional shape may be a hollow shape or a solid shape.
[0029]
Examples of the hollow shape include a tunnel shape in which a hollow portion is opened to one side, a tube shape having a hollow cross-sectional shape in which the entire periphery is closed, and a spirally curled shape.
[0030]
Further, the solid shape is a shape in which a part of the spacer tape in the width direction is formed to be thick. However, a method for forming the thick part is not particularly limited. It also includes a method in which a part of the tape body is folded in a zigzag manner and preferably joined together, and a shape in which a part of the tape body in the width direction is curled in a dense spiral shape.
[0031]
Of course, as described above, the hollow or solid projection may be formed of the same material as the tape main body, or may be formed of a different material including the composite material.
[0032]
Next, another spacer tape of the present invention (hereinafter, referred to as the second tape of the present invention) includes projections protruding on one or both of the front and back sides of the tape main body on both side edges of the tape main body in order to achieve the above object. In a spacer tape comprising: technical means, at least a part of the projection is provided so as to be in contact with each other on one or both sides.
[0033]
According to this, the spacer tape can be wound around the reel such that there is no gap in the tape longitudinal direction between the protrusions on the front side or the back side of the spacer tape. It does not fit between the protrusions of the spacer tape that overlaps inside. As a result, it is possible to reliably prevent the corners of the protrusions of the outer spacer tape from being cut between the protrusions of the inner spacer tape and locally deforming the spacer tape and the tab tape.
Hereinafter, the second tape of the present invention will be described in more detail.
[0034]
The second tape of the present invention includes a tape having projections formed on one side of the tape body, that is, a tape body having projections formed on one side thereof, and a tape having projections formed on both sides of the tape body.
[0035]
In the case where the projection is formed on one side, at least a part of the projection adjacent to the one side in the tape longitudinal direction is provided so as to be in contact with each other.
[0036]
In this case, as a method of forming the projection, embossing, injection molding in which the tape body is part of a molding die, and the like can be adopted, and a separately formed projection is bonded and melted to a preformed tape body. A method of joining by welding, welding, welding, pressure bonding, fitting, or the like can be adopted.
[0037]
If the protrusions are provided on both sides of the spacer tape so as to be in contact with other protrusions adjacent in the tape longitudinal direction, the positions of the protrusions on both surfaces and the spacing in the tape longitudinal direction may be different, but the structure is simplified and In order to facilitate manufacture, it is preferable to form the protrusions on both sides at the same interval and at the same position.
[0038]
As a method of forming the projections on both surfaces, injection molding in which the tape body is part of a molding die is optimal, but in addition to this, a projection separately formed on the tape body formed in advance is bonded, fused, A method of joining by welding, welding, pressure bonding, fitting, or the like can be adopted.
[0039]
By the way, when protrusions are provided on both surfaces of the tape body and the protrusions on both surfaces are provided so as to be in contact with other protrusions adjacent at least in part in the tape longitudinal direction, the spacer tape is wound around the reel in order to wind the spacer tape around the reel. When bent in the thickness direction, adjacent projections inside the bend must not stick to each other with a certain pressure or more.
[0040]
For this reason, a gap is formed between adjacent projections on the inner surface of the bend such that the gap gradually increases from the bottom of the projection toward the top of the projection, or at least one other projection that projects on the inner surface of the bend has a tape longitudinal direction. It is necessary that both ends or one end or both ends in the tape longitudinal direction of each projection be configured to be compressively elastically deformable.
[0041]
Here, the method of forming one end or both ends of the protrusion in the tape longitudinal direction so that the protrusion can be compressed and elastically deformed is not particularly limited. For example, the protrusion may be formed of a polymer composition having elasticity such as rubber or elastic. Or a method of forming with a foamed synthetic resin having In addition to or in place of such material selection, it is also possible to adopt a method of giving shape elasticity, for example, forming one or both ends in the longitudinal direction of the projection in a bellows shape.
[0042]
The protrusions adjacent in the tape longitudinal direction may be in point contact, line contact, or surface contact with each other, for example, between the bottoms of the protrusions, as viewed from the tape width direction, or may be in line contact or over the entire height of the protrusions. Surface contact may be made.
[0043]
When the projections are in line contact or surface contact, the contact line or contact surface is a curved line that connects a plurality of straight lines having different inclinations, even if the contact line or the contact surface is a straight line or a curve when viewed from the tape width direction. Alternatively, it may be a composite line in which a straight line and a curve are connected continuously or discontinuously. In addition, the contact line or the straight line that constitutes a part or all of the contact surface as viewed from the tape width direction may rise perpendicularly to the tape surface or be inclined with respect to the tape surface.
[0044]
Whether the contact line or contact surface viewed from the tape thickness direction is a straight line or a curved line, or a bent line connecting a plurality of straight lines having different inclinations, the straight line and the curved line are continuously It may be a composite line connected continuously. In addition, the contact line or the straight line that forms part or all of the contact surface as viewed from the tape thickness direction may be parallel to the tape width direction or may be inclined with respect to the tape width direction.
[0045]
When protrusions are provided on both surfaces of the tape body, and the protrusions on both surfaces are provided at least in part at least in contact with other protrusions adjacent in the tape longitudinal direction, between the protrusions outside the bend of the bent spacer tape. Although a gap is generated, it is possible to eliminate the gap by elastic restoration of the projection.
[0046]
That is, the protrusions on both sides are formed such that adjacent protrusions are in surface contact with each other when the spacer tape is unfolded, and the surfaces of the adjacent protrusions overlap each other when viewed in the thickness direction of the tape. When the spacer tape is configured to be elastically deformed by pressing the other, when the spacer tape is bent in its thickness direction, the adjacent protrusions are elastically restored, so that no gap is formed between the protrusions on the outer side of the bend. .
[0047]
As a method of providing a projection on at least a part of both surfaces of the tape body so as to be in contact with another projection adjacent to the tape in the longitudinal direction, there are injection molding in which the tape body is part of a molding die and injection molding in which the projection is part of a molding die. Molding or the like can be adopted, but other methods such as bonding, fusion, welding, welding, crimping, fitting, and the like of a separately formed projection on a preformed tape body can also be adopted. .
[0048]
By the way, in the first tape and the second tape of the present invention, the positioning grooves for positioning the tab tape on the protrusions formed on both side edges of one side of the tape body are continuously or intermittently formed in the longitudinal direction. It is preferable that the tab tape is formed in such a manner that the tab tape can be easily mounted on the spacer tape, and the displacement is less likely to occur.
[0049]
Further, the first tape and the second tape of the present invention may each have a full length to be wound around a reel, but if necessary, a tape body and a projection may be formed in a block of a predetermined length. Alternatively, a spacer tape of a required length may be obtained by adding each block.
[0050]
The connection between the blocks may be performed by using a separate member such as a steeple, an adhesive tape, an adhesive tape, or a connecting means for connecting the blocks to both ends in the tape longitudinal direction of each block. For example, a configuration may be adopted in which a male / female fitting connection means is provided.
[0051]
As described above, when a block having an appropriate length is formed and added to form a spacer tape having a required length, an appropriate number of blocks are added to correspond to the diameter of the reel. It is possible to obtain spacer tapes with different overall lengths, and it is not necessary to manufacture many types of spacer tapes with different lengths corresponding to the difference in reel diameter, and it is not necessary to store them. This has the advantage of reducing product inventory and reducing material and storage costs.
[0052]
Next, the tab tape spacer according to the present invention includes a tape insertion groove into which a side edge of the tab tape is inserted, and a tab having a predetermined height in a groove width direction of the tape insertion groove. It employs technical means of being composed of a body.
[0053]
According to this, when both side edges of the tab tape are inserted into the tape insertion grooves of the tab tape spacer and wound around the reel, the interval between the tab tapes wound inside and outside due to the overlapping of the strips inside and outside of the tab tape is increased. It is held constant over the entire length.
[0054]
Moreover, since the strips are continuous in the longitudinal direction, there is no danger that the strip wound outside will be locally fitted between the strips wound inside, and local deformation on the tab tape, that is, No bending occurs.
[0055]
Further, by eliminating the local deformation of the tab tape, the position of the electronic component in the longitudinal direction of the tab tape is prevented from changing, and the location accuracy in the component mounting process can be improved.
[0056]
Hereinafter, the tab tape spacer of the present invention will be described in more detail.
The strip is required to have flexibility enough to be wound on a reel, and is required to have rigidity or shape retention such that the cross-sectional shape does not change more than a certain value when wound. The protrusions of the first tape of the present invention or the second tape of the present invention may be made of the same material.
[0057]
Further, the cross-sectional shape of the strip may be a shape provided with a tape insertion groove recessed from one location on the peripheral surface to the center portion, and a shape having a predetermined height in a groove width direction of the tape insertion groove. Equipped with a tape insertion groove that is recessed into the center from one point on the peripheral surface of any shape such as a polygon such as a circle, a crescent, an ellipse, a gourd, a rectangle, a square, a triangle, a trapezoid, or a pentagram A cross-sectional shape can be adopted.
[0058]
Further, a positioning projection is protruded at one end in the groove width direction of the tape insertion groove of the strip, and a positioning groove corresponding to the positioning projection is formed at the opposite end on the entire length of the strip. Then, since the positioning projections and the positioning grooves of the strips wound inside and outside mesh with each other, the positions of the strips in the tab tape width direction are positioned with respect to each other. And the location accuracy in the tab tape width direction in the component mounting process can be increased.
[0059]
Further, in this case, since the positions of the wound strip and the tab tape in the tab tape width direction can be kept constant, the interval between the flanges of the reel can be reduced.
[0060]
Examples of the positioning projection include a ridge that is continuous over the entire length of the strip, a ridge that is intermittent over the entire length of the strip, or a point-shaped projection that is disposed at a predetermined interval in the longitudinal direction of the strip. It can be mentioned as.
[0061]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be specifically described with reference to the drawings, but the present invention is not limited to these embodiments.
[0062]
In the drawings, FIG. 1 is a perspective view of a spacer tape according to one embodiment of the present invention. The spacer tape shown in FIG. 1 is formed in a tunnel shape that is continuous over the entire length of the tape body 1 on both sides thereof. Provided projection 2.
[0063]
The protrusions 2 protrude both side edges of a single synthetic resin tape raw material to the front surface side of the tape main body 1 by, for example, heating roll forming, and have a horseshoe-shaped tunnel shape having a cross-sectional shape opened to the back side of the tape main body 1. It was formed.
[0064]
When this spacer tape is wound around a reel together with a tab tape carrying electronic components, the protrusion 2 is elastically deformed so as to decrease in the tape thickness direction and to increase in the tape width direction. Is designed in anticipation of a decrease due to this elastic deformation.
[0065]
According to this spacer tape, since the projections 2 are continuous in the longitudinal direction of the tape, there is no possibility that there is a gap between the projections 2 that opens in the longitudinal direction of the tape. Even if there is a shift in the tape longitudinal direction between the tape tape and the protrusion 2 wound inside, the deformation of the tab tape or the spacer tape can be reliably prevented.
[0066]
As a result, according to the spacer tape, the electronic component is scratched by the contact between the spacer tape and the electronic component, or the lead of the electronic component is deformed by the elastic or plastic deformation of the tab tape or the spacer tape, and the component is mounted. It is possible to obtain an effect that it is possible to reliably prevent the occurrence of a defective electronic component before the sending step and an effect that it is possible to reliably prevent the generation of a defective board due to the mounting of the defective electronic component in the component mounting step.
[0067]
Further, according to this spacer tape, it is possible to surely prevent the tab tape from being plastically deformed and the electronic component from moving with respect to the tab tape, or the gap between the electronic components held by the tab tape in the tape longitudinal direction being deviated. In addition, it is possible to obtain the effect that the locating accuracy in the component mounting process can be improved and the occurrence of a defective board due to a locating defect can be reliably prevented.
[0068]
FIG. 2 is a perspective view of a modification of the embodiment shown in FIG. 1. As shown in FIG. 2, this modification uses a similar manufacturing method to open the tunnel-shaped projection 2 from both sides of the tunnel-shaped projection 2 of the previous example. A tube-shaped projection 2 is formed by providing a folded portion 2a so as to close the surface.
[0069]
According to this embodiment, one of the projections 2 wound inside and outside can be reliably prevented from being pushed into the other projection 2 from the open surface of the other projection 2, and the wound tape body 1 can be prevented. Can be maintained more accurately, so that it is possible to more reliably prevent the occurrence of defective electronic components before the component mounting and feeding process due to scratching of electronic components or deformation of leads of electronic components. In addition, it is possible to obtain an effect that generation of a defective board due to mounting of a defective component in the component mounting process can be more reliably prevented.
[0070]
In this embodiment, in order to more reliably prevent one of the projections 2 wound inside and outside from entering the other, the portion turned back from the projection 2 and the tape body from the tape thickness direction. Although they are partially overlapped in the tape width direction, they do not need to be overlapped in this way.
[0071]
Further, in this embodiment, in order to avoid an increase in cost, the overlapped portions are simply overlapped with each other, but the overlapped portions are fixed to each other by, for example, adhesion, fusion, welding, or adhesion. Then, it is possible to further reliably prevent one of the projections 2 wound inside and outside from entering the other.
[0072]
FIG. 3 is a perspective view of a spacer tape according to another embodiment of the present invention. This spacer tape is obtained by molding a single synthetic resin tape with a heating roller, and is a tape formed in an extended shape. The main body 1 and both side edges thereof are provided with protrusions 2 which are uniformly projected on both sides of the tape main body 1 and are continuous over the entire length in the tape longitudinal direction.
[0073]
The projection 2 is formed in a circular cross section, and the neutral axis of the tape body 1 and the neutral axis of the projection 2 are aligned with each other when viewed from the tape width direction. No tension or pressure is applied to 1.
[0074]
In this embodiment, the tape body 1 and the protrusion 2 are formed of the same material. For example, the tape body 1 is formed of an extruded material of a synthetic resin such as polyetherimide, polyimide, polyethylene triphthalate, and the like. 2 may be formed of an extruded (co-extrusion) molded material different from the tape body 1 such as synthetic rubber. When the tape body 1 and the projection 2 are made of different materials, they may be separately formed and bonded by adhesion, fusion, welding, forging, pressure bonding, etc., for example, by simultaneous extrusion (co-extrusion). It may be molded at the same time.
[0075]
The operation and effect of this embodiment are the same as those of the embodiment of the present invention shown in FIG.
[0076]
FIG. 4 is a partially exploded perspective view showing a spacer tape according to a modification of the embodiment shown in FIG. 3, and in another embodiment of the present invention shown in FIG. In the modification shown in FIG. 4, the tape body 1 is formed of a film or sheet made of a synthetic resin such as polyetherimide, polyimide, or polyethylene naphthalate, and the projections 2 are formed of, for example, a synthetic resin. It is formed of an extruded material different from the tape body 1 such as rubber.
[0077]
The cross-sectional shape of the projection 2 is substantially circular, and has a tape insertion groove 2b which is recessed from one location on the peripheral surface to the center.
[0078]
Here, both side edges in the longitudinal direction of the tape body 1 are inserted into the tape insertion grooves 2b of the protrusions 2, respectively, and if necessary, the tape body 1 and the protrusions 2 are non-disassembled by, for example, bonding or fusion. However, the tape body 1 and the projection 2 may be simply fitted together, and the tape body 1 and the projection 2 may be disassembled after use.
[0079]
When the tape main body 1 and the projection 2 are made of different materials, the tape main body 1 and the projection 2 can be simultaneously formed by, for example, co-extrusion (co-extrusion).
[0080]
Of course, other configurations, operations, and effects of this modified example are the same as those of the above-described embodiments, and thus description thereof will be omitted.
[0081]
In this modification, instead of the tape body 1 of the spacer tape, the side edge of the tab tape can be inserted into the tape insertion groove 2b of the projection 2, and the projection 2 can be used as a tab tape spacer.
[0082]
In this case, the projection 2 and the tab tape may be joined in a non-decomposable manner by bonding, fusion or the like, but these are fitted so as to be decomposable, and the tab tape and the projection (tab tape spacer) 2 are disassembled after use. It is preferable to be able to reuse each possible range.
[0083]
When the projections 2 are used as tab tape spacers as described above, when both side edges of the tab tape are inserted into the tape insertion grooves 2b of the projections (tab tape spacers) 2 and wound around a reel, the strips are mutually separated. By overlapping inside and outside, the interval between the tab tapes wound inside and outside is kept constant over the entire length of the tab tape, and it is possible to reliably prevent the electronic components or the electronic component and the tab tape from rubbing each other. As a result, there is no possibility that the electronic component is damaged or the lead of the electronic component is deformed, and it is possible to reliably prevent the tab tape from being wound around the reel, that is, to prevent the electronic component from being defective due to reeling.
[0084]
Moreover, since there is no risk that a gap is formed in the strip in the longitudinal direction, there is no possibility that the strip wound outside will fit into the gap between the strips wound inside and locally deform the tab tape. As a result, the location accuracy in the longitudinal direction of the tab tape can be improved, so that the occurrence of a defective substrate due to a location defect can be prevented.
[0085]
FIG. 5 is a partially exploded perspective view showing a modification obtained by further modifying the modification shown in FIG. 4. In this modification, a cross section continuous to the top surface of each projection 2 over the entire length of each projection 2 is shown. Positioning projections 2c each formed of a ridge having a triangular shape, and positioning concave grooves 2d formed on the bottom surface of each projection 2 and having an inverted V-shaped cross section continuous over the entire length of each projection 2 are provided. Is formed.
[0086]
As a result, the positioning protrusions 2c of the inner spacer tape are fitted into the positioning grooves 2d of the spacer tape which is wound outwardly when wound on the reel, and the position of the spacer tape which is wound inside and outside in the tab tape width direction. Is regulated to be constant, so that the location accuracy in the component mounting process can be improved, and the interval between the tape bodies 1 of the spacer tape is accurately kept constant to ensure the contact between the tape body 1 and the electronic components. Can be prevented.
[0087]

FIG. 9 is a perspective view of a spacer tape according to a modification different from that of the embodiment shown in FIG. 3. As shown in FIG. 9, in this modification, a tab tape is attached to each protrusion 2 in the tape width direction. A guide positioning groove 2g for positioning is formed.
[0096]
Although the positioning grooves 2g are formed only on the front side of the tape main body 1 as shown in FIG. 9, they may be formed on both front and back sides of the tape main body 1.
[0097]
According to this embodiment, the tab tape is positioned between the positioning grooves 2g of the protrusions 2 at both ends in the tape width direction to position the tab tape in the tape width direction, so that the tab tape moves in the tape width direction with respect to the spacer tape. It is possible to prevent the electronic component from rubbing against the tape body 1 and the protrusion 2, and to improve the location accuracy of the electronic component in the tape width direction.

[0104]
FIG. 12 is a side view of a spacer tape according to still another embodiment of the present invention. In this embodiment, a large number of protrusions 2 are provided on the tape surface side in the longitudinal direction of the tape. The adjacent projections 2 are provided so as to be in contact with each other when deployed. The protrusion 2 is fixed to the tape body 1 by, for example, an insert molding method, an injection molding method, or the like.
[0105]
According to this embodiment, when the tape body 1 is wound on a reel so as to be bent to the back side as shown by a two-dot chain line in FIG. 7, the projections 2 on the front side are in contact with each other in the longitudinal direction of the tape. 2, there is no gap extending in the longitudinal direction of the tape. Actually, a minute gap is formed, but this gap can be functionally ignored compared to the length of the protrusion 2 in the tape longitudinal direction. For this reason, there is no possibility that the protrusion 2 of the spacer tape wound on the outside will fit between the protrusions 2 of the spacer tape wound on the inside.
[0106]
Also, when an external force is applied to the spacer tape to bend to the surface side where the protrusion 2 is in contact, the protrusions 2 of the spacer tape are stuck and do not bend from the deployed state to the surface side. The possibility that the protrusions 2 of the tape are protruded between the protrusions 2 of the spacer tape wound inside is surely eliminated, and the protrusions 2 of the spacer tape wound outside are between the protrusions 2 of the spacer tape wound inside. The possibility that the spacer tape or the tab tape is locally deformed due to the intrusion surely disappears.
[0107]
Other configurations, operations, and effects of this embodiment are the same as those of each of the above-described embodiments, and will not be described.
[0108]
FIG. 13 is a side view of a spacer tape which is a modification of the still another embodiment of the present invention shown in FIG. 11. The spacer tape shown in FIG. 8 has adjacent projections 2 (A), 2 (V ) Are in surface contact over the front height.
[0109]
That is, this spacer tape is formed by fixing A-shaped projections 2 (A) and V-shaped projections 2 (V) on both sides of the tape body 1 alternately in the longitudinal direction of the tape, and these A-shaped projections 2 (A). And the V-shaped projection 2 (V) are formed at the same height, and although not particularly limited, the length La of the A-shaped projection 2 (A) in the tape longitudinal direction and the V-shaped projection 2 (V) Is equal to the length Lv in the tape longitudinal direction.
[0110]
Here, the A-shaped projection 2 (A) is a shape in which the dimension in the longitudinal direction of the projection 2 (A) decreases continuously and / or stepwise toward the top of the projection 2 (A), or The protrusion 2 (A) has a uniform shape in the longitudinal direction, that is, a tapered or rectangular protrusion 2 (A). The one formed on the curved surface is used.
[0111]
Further, the V-shaped projection 2 (V) means that the dimension in the longitudinal direction of the projection 2 (V) in contact with the surface of the tape body 1 is continuously and / or stepwise toward the top of the projection 2 (V). Or a shape in which the length of the protrusion 2 (V) in the longitudinal direction is uniform, that is, a protrusion 2 (V) having a divergent shape or a rectangular shape in a side view. Both ends in the longitudinal direction of the tape are formed into a convex curved surface corresponding to the concave curved surface of the A-shaped projection 2 (A), and the tape is formed so that the A-shaped projection 2 (A) and the V-shaped projection 2 (V) are in contact with each other on the entire curved surface. It is fixed to the main body 1.
[0112]
Here, when viewed from the tape width direction, the contact surface between the A-shaped projection 2 (A) and the V-shaped projection 2 (V) is formed as a curved surface that is convex toward the A-shaped projection 2 (A). However, it may be formed on a curved surface protruding toward the V-shaped projection 2 (V), or may be formed on a plane inclined with respect to the surface of the tape main body 1, and further perpendicular to the surface of the tape main body 1. It may be formed on a flat surface, or may be formed on a bent surface. In addition, the contact surface is formed parallel to the tape width direction, but may be inclined in the tarp width direction, or may be curved in the tape thickness direction, for example, in an arc shape or S-shape, It may be bent into a letter shape or a crank shape.
[0113]
The A-shaped projection 2 (A) and the B-shaped projection 2 (B) are made of an elastic material such as synthetic rubber, for example. When the spacer tape is bent, the protrusions 2 (A) and 2 (V) on the outside are bent. Although a widening gap is generated, the protrusions 2 (A) and 2 (V) inside the bend are in close contact with each other while being compressed and elastically deformed, and protrusions having the same height are formed continuously in the longitudinal direction of the tape.
[0114]
Accordingly, there is no possibility that the protrusions 2 (A) and 2 (V) of the spacer tape wound outside will fit between the protrusions 2 (A) and 2 (V) of the spacer tape wound inside. The protrusions 2 (A) and 2 (V) of the spacer tape wound around the spacer tape may fit between the protrusions 2 (A) and 2 (V) of the spacer tape wound inside and the spacer tape or tab tape may be deformed. Is also gone.
[0115]
However, even if the outer projections 2 (A) and 2 (V) are elastically restored and are not connected to each other, and a gap is formed between the projections 2 (A) and 2 (V), the projections 2 (A) and 2 ( Since (V) is continuous, the outer protrusions 2 (A) and 2 (V) do not fit between the inner protrusions 2 (A) and 2 (V).
[0116]
FIG. 14 is a side view of a spacer tape according to another embodiment of the present invention. As shown in FIG. 14, this spacer tape has A-shaped protrusions 2 (A) alternately arranged on both sides in the tape longitudinal direction. V-shaped projections 2 (V), and the projections 2 (A) are arranged such that the edges of the A-shaped projections 2 (A) and the edges of the V-shaped projections 2 (V) are continuous in the tape thickness direction. , 2 (V).
[0117]
The length Lg of the gap in the longitudinal direction of the tape may be designed empirically. For example, the length Lg of the top surface or the top ridge line of the A-shaped projection 2 (A) is １ (la / la). 2) It is preferable that the length is not more than one. In this embodiment, the length is designed to be 1/4 (la / 4) of the length la in the tape longitudinal direction of the top surface or the top ridge line of the A-shaped projection 2 (A). I have.
[0118]
Thus, when the A-shaped projections 2 (A) and the V-shaped projections 2 (V) are alternately arranged in the longitudinal direction of the tape, as shown in the side view of FIG. When an external force P is applied from the outside to a point T where the edges of the V-shaped projection 2 (V) and the inner V-shaped projection 2 (V) abut, the V-shaped projection 2 (V) indicated by the outer hatching becomes T It is easy to be pushed between the inner protrusions 2 (A) and 2 (V) adjacent to the left and right across the point.
[0119]
However, in this case, as shown in an exaggerated manner by a two-dot chain line in FIG. 14, for example, the V-shaped projection 2 (V), the V-shaped projection 2 (V) on the surface side, the left inner side from the T point, the surface The A-shaped projection 2 (A) on the side, the A-shaped projection 2 (A) on the front and back surfaces on the right outside, the V-shaped projection 2 (V) on the right inside surface side, and the tape body 1 are elastically deformed.
[0120]
In FIG. 14, the tape main body 1 of the inner spacer tape and the projections 2 (A) and 2 (V) on the back side (core side) are shown not to be elastically deformed. The tape is also gradually elastically deformed toward the inside rather than the outside.
[0121]
As described above, since the external force P is dispersed and received by the plurality of turns of the spacer tape, the external force received by the outer spacer tape is reduced, and its deformation is gradual and small. There is no deformation. Further, since the amount of deformation of the outer tape body 1 in the tape thickness direction is small, the outer tape body 1 is not rubbed against the electronic components.
[0122]
Further, when the external force P is removed, the V-shaped projection 2 (V), the V-shaped projection 2 (V) on the surface side, the left inside from the point T, the A-shaped projection 2 (A) on the front side, and the right outside. The tape body 1 is pushed back to a normal position by the elastic restoration of the A-shaped protrusion 2 (A), the right inner V-shaped protrusion 2 (V) and the tape body 1, so that the location accuracy is not impaired.
[0123]
Of course, since the distance Lg between the A-shaped projection 2 (A) and the V-shaped projection 2 (V) is set to one quarter of the length La of the top surface or the top ridge line of the A-shaped projection 2 (A). The protrusions 2 (A) and 2 (V) of the outer spacer tape do not deviate from the inner protrusions 2 (A) and 2 (V), and as described above, the position of the tape body 1 when the external force P disappears. Will return to the normal position, and the tape body 1 wound inside and outside will be accurately and uniformly spaced.
[0124]

[0126]
In addition, the above action can prevent the tab tape from being locally bent together with the spacer tape, and can prevent the electronic component from moving with respect to the tab tape due to the local bending of the tab tape. The effect of being able to increase can be obtained.
[0127]
The second tape of the present invention is a spacer tape having projections protruding on one or both sides of the tape main body on both side edges of the tape main body, wherein at least a part of the projections adjacent in the tape length direction is one of the front and back sides or Since the spacer tape is provided so as to be in contact with each other, the spacer tape can be wound around the reel so that there is no gap between the protrusions on the front side or the back side of the spacer tape, and the reel is wound outward. It is possible to obtain an effect that the protrusion of the spacer tape can be completely prevented from being fitted between the protrusions of the spacer tape wound inside.
[0128]
By this action, local bending of the spacer tape can be prevented, and the local bending of the spacer tape can prevent the electronic components from being scratched or deforming the leads of the electronic components. It is possible to obtain an effect that it is possible to prevent a defective electronic component from being generated before.
[0129]
In addition, the above action can prevent the tab tape from being locally bent together with the spacer tape, and can prevent the electronic component from moving with respect to the tab tape due to the local bending of the tab tape. The effect of being able to increase can be obtained.
[0130]
Next, the tab tape spacer of the present invention includes a tape insertion groove into which a side edge portion of the tab tape is inserted, and is formed of a strip having a predetermined height in a groove width direction of the tape insertion groove. Therefore, according to this, when the both side edges of the tab tape are inserted into the tape insertion grooves of the tab tape spacer and wound on the reel, the interval between the tab tapes wound inside and outside due to the overlapping of the strips inside and outside each other. The effect that the tab tape is kept constant over the entire length can be obtained.
[0131]
And, by this action, the electronic components or the electronic components and the tab tape are reliably prevented from rubbing each other, the electronic components are scratched, the tab tape wear debris adheres to the electronic components, and the leads of the electronic components are deformed. This eliminates the possibility that the electronic component will fail, and can reliably prevent the occurrence of defects in the electronic component due to reeling (winding of the electronic component around the reel).
[0132]
In addition, since there is no possibility that a gap is formed in the strip in the longitudinal direction, there is no possibility that the strip wound on the outside fits into the gap between the inner strips and the tab tape is locally deformed. With this operation, the position of the electronic component in the longitudinal direction of the tab tape does not fluctuate, and the location accuracy in the longitudinal direction of the tab tape in the component mounting process can be improved. Can be obtained.
