Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a spacer tape and a tab tape spacer that can reliably prevent deformation of a tab tape.
[0002]
[Prior art]
Generally, a spacer tape is a protrusion that protrudes in the thickness direction on one or both of the front and back sides of both side edges so that tab tapes wound around the reel are wound at appropriate intervals in the radial direction of the reel. It has.
[0003]
For example, as described in JP-A-11-45914 and JP-A-7-285576, this protrusion is formed by deforming a part of the tape by embossing, or Japanese Patent Publication No. 8-19116. In other words, it is formed by injection molding.
[0004]
[Problems to be solved by the invention]
By the way, the projections of these conventional products are arranged in the longitudinal direction of the tape at an appropriate interval, so that when they are wound around the reel together with the tab tape, the position of the projection that overlaps inside and outside is shifted in the longitudinal direction of the tape, and the inside projection In some cases, an outer protrusion fits between the tab tape and the spacer tape.
[0005]
Further, the deformation of the tab tape and the spacer tape causes defective products due to damage of the electronic component package due to frictional contact between the electronic component and the spacer tape, deformation of the lead of the electronic component, or the like.
[0006]
Furthermore, the deformation of the lead of the electronic component and the plastic deformation of the tab tape cause a decrease in location accuracy and generation of defective products in the component mounting process on the substrate due to the movement of the electronic component.
[0007]
In the spacer tape described in JP-A-11-45914, the width of the truncated 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. Thus, the outer protrusion is prevented from being fitted between the inner protrusions.
[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 is concentrated at the corners of the protrusions, and the spacer tape and the tab tape are plastically deformed, so that the location accuracy of the electronic components in the mounting process of the electronic components on the board is reduced and defective products are generated. Cannot be solved.
[0009]
It is an object of the present invention to provide a spacer tape that solves the problems of the prior art and can reliably prevent deformation of the 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 in the thickness direction on one or both of the front and back sides of the tape at both longitudinal edges of the tape body. In a spacer tape having a protruding protrusion, the protrusion is continuously formed over the entire length of the tape body.And the said protrusion is formed in the tunnel shape which has the cross-sectional shape which has the hollow part open | released in one surface.The technical means characterized by this is adopted.
[0011]
According to this, since the protrusions are continuous over the entire length of the tape body, the inner and outer intervals of the tape body wound on the reel are accurately and uniformly maintained, and the tab tape and the spacer tape are locally deformed, that is, bent. The risk of occurrence is completely eliminated.
Hereinafter, the first tape of the present invention will be described in more detail.
[0012]
First, the tape main 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]
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, vegetable fiber, or a composite material of two or more of these. That's fine.
[0014]
Furthermore, the shape of the tape body is not particularly limited as long as it is in the form of a tape that is long in the longitudinal direction.For example, it has an extended surface, and has an opening for saving materials and lightening including a ladder shape. A known shape such as a net shape may be employed.
[0015]
Furthermore, the method for 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, or die casting, or can be formed by various film forming methods. A method of obtaining a tape roll by slicing the roll at an appropriate interval in the axial direction may be adopted.
[0016]
The protrusions in the first tape of the present invention may be any protrusion that protrudes in the thickness direction on one or both of the front and back sides of the tape body at both side edges in the longitudinal direction of the tape body. It is preferable that the tape body is projected evenly on both the front and back surfaces so that the pressure and tension acting on the tape body are zero or almost eliminated. In other words, it is preferable that the neutral axis in the thickness direction of the tape body and the neutral axis in the tape thickness direction of the protrusions coincide with each other when viewed from the tape width direction.
[0017]
When providing protrusions on both front and back sides of the tape body, it is not necessary to match the position of the protrusions in the tape width direction on both the front and back sides.For example, the protrusions on the front side are placed at both ends of the entire width of the tape, and the protrusions on the back side Place one protrusion on the front side of the tape, one protrusion on the front side at one end of the entire width of the tape, the other on the inner side of the tape, and 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 tape width on the tape center side.
[0018]
However, in order to reduce the total width of the spacer tape and 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 the front and back sides. It is preferable.
[0019]
The protrusions need to have bending elasticity in the cross-sectional direction as in the case of the tape body, but the method for obtaining the bending elasticity is not particularly limited. For example, the method for selecting the material and the method for selecting the shape The method of selecting a material is a method of forming a protrusion with an elastic polymer composition such as rubber, and the method of selecting a shape is, for example, a cross-sectional shape. It is a method of forming an open figure, forming it hollow, or forming it thin.
[0020]
In selecting the material of the protrusion, the protrusion material can be the same or different from that of the tape, and if it is the same quality, the tape body and the protruding part can be extruded, injection molded, mold flow In addition to being able to be formed simultaneously by any resin molding technique such as molding, tape-shaped materials can be formed simultaneously, for example by hot roll molding or cold roll molding to make the tape body thin and the protrusions thick. After the formation, the end portion of the tape body can be formed by plastic working such as flanging, curling, roll forming, multi-stage pressing, or the like, or heat plastic working or heating die working.
[0021]
Here, plastic working is a process of plastically deforming a material with externally applied stress, that is, external stress, and heat plastic working is a process of plastically deforming with external stress while heating the material, Heating mold processing is to heat a material against a mold including rolls and rails, and intermolecular tension of the material, intermolecular repulsive force, intermolecular tension difference between heated surface and non-heated surface, between heated surface and non-heated surface. It is a process to adjust to the mold by internal stress such as intermolecular repulsion.
[0022]
Even when the material of the protrusions is different from that of the tape body, it is possible to form the protrusions simultaneously with the molding of the tape body, for example, by simultaneous extrusion molding, simultaneous injection molding, sequential casting, etc.
[0023]
Of course, even if the tape body and the protrusion are made of the same or different materials, the tape body and the protrusion are separately formed in advance, and the tape body and the protrusion are bonded, fused, welded, welded, crimped, for example. It is also possible to join by a technique such as fitting.
[0024]
Further, 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 and a synthetic resin of the same or different quality from the tape body.
[0025]
As this composite material, for example, a composite material composed of a synthetic resin, a chain made of a metal, or the like, and a synthetic resin, a wire including a single wire or a stranded wire made of metal, animal fiber, plant fiber, etc. and a synthetic resin There is.
[0026]
Examples of the composite structure of the strip and the synthetic resin include an impregnation structure in which the strip is impregnated with a synthetic resin, a mold structure in which a 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.
[0027]
In addition, the composite material is different from the reinforcing material so that the end portions in the tape longitudinal direction overlap each other when a number of reinforcing materials having a predetermined height in the tape thickness direction are 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 from metal, synthetic resin of the same or different quality as the tape body.
[0028]
  The shape of the protrusion may be a shape protruding in the tape thickness direction on one or both of the front and back of the tape, and its cross-sectional shape isIt is a tunnel type with a hollow part open to one side.
[0031]
  Of course, as mentioned above,HollowThe protrusions may be made of the same material as the tape body or may be made of a different material including the composite material.
[0032]
  Next, in order to achieve the above object, another spacer tape of the present invention (hereinafter referred to as the second tape of the present invention) is a protrusion protruding on one or both of the front and back of the tape body at both side edges of the tape body. In the spacer tape comprising: at least a part of the protrusions are provided so as to contact each other on one or both of the front and back sidesThe protrusions adjacent to each other are formed so as to come into surface contact with each other when the spacer tape is unfolded, and the contact surfaces of the adjacent protrusions overlap each other when viewed from the tape thickness direction.Adopt technical means.
[0033]
According to this, the spacer tape can be wound around the reel so that there is no gap in the tape longitudinal direction between the protrusions on the front surface side or the back surface side of the spacer tape. It does not fit between the protrusions of the spacer tape that overlap inside. As a result, it is possible to reliably prevent the corners of the protrusions of the outer spacer tape from being caught 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 one having protrusions formed on one side of the tape body, that is, one side of the tape body, and one having protrusions formed on both sides of the tape body.
[0035]
In the case where projections are formed on one side, at least a part of the projections adjacent to each other in the longitudinal direction of the tape is provided so as to be in contact with each other.
[0036]
In this case, as a method of forming the protrusion, embossing, injection molding in which the tape body is used as a part of the mold, and the like, a protrusion formed separately on the previously formed tape body is bonded and melted. A method of joining by welding, welding, welding, pressure bonding, fitting, or the like can be employed.
[0037]
When protrusions are provided on both sides of the spacer tape so as to contact other protrusions adjacent in the longitudinal direction of the tape, the position of the protrusions on both sides and the distance in the longitudinal direction of the tape may be different. In order to enable easy manufacture, it is preferable to form the protrusions on both sides at the same interval and at the same position.
[0038]
As a method for forming the protrusions on both sides, the injection molding in which the tape body is used as a part of the molding die is optimal, but in addition to this, the protrusions separately formed on the tape body formed in advance are bonded, fused, A method of joining by welding, welding, pressure bonding, fitting, or the like can be employed.
[0039]
By the way, when protrusions are provided on both sides of the tape main body, and the protrusions on both sides are provided so as to be in contact with other protrusions adjacent in the longitudinal direction of the tape, at least a part of the tape is used to wind the spacer tape around the reel. When bent in the thickness direction, adjacent protrusions on the inner side of the bending must be prevented from sticking to each other with a certain pressure or more.
[0040]
For this reason, a gap is formed between the adjacent protrusions on the inner surface of the bend to gradually increase the distance from the bottom of the protrusion toward the top of the protrusion, or the tape longitudinal direction of at least every other protrusion protruding on the inner surface of the bend It is necessary to configure such that both end portions or one end portion or both end portions of each protrusion in the longitudinal direction of the tape can be compressed and elastically deformed.
[0041]
Here, the method of configuring one end or both ends of the protrusion in the tape longitudinal direction so as to be able to compressively elastically deform is not particularly limited. For example, the protrusion is formed of rubber or other polymer composition having elasticity, or elastic There is a method of forming with a foamed synthetic resin. In addition to or in place of such material selection, a method of giving elasticity in shape, for example, forming one end portion or both end portions in the longitudinal direction of the protrusion in a bellows shape may be employed.
[0042]
The protrusions adjacent to the longitudinal direction of the tape may be point-contacted, line-contacted, or surface-contacted with a part of the bottoms of the protrusions, for example, when viewed from the tape width direction. You may make surface contact.
[0043]
When the protrusions are brought into line contact or surface contact, the contact line or contact surface is a bent line connecting a plurality of straight lines with different inclinations, whether it is a straight line or a curved line when viewed from the tape width direction. Alternatively, it may be a composite line in which straight lines and curved lines are connected continuously or discontinuously. Further, the contact line or a straight line constituting part or all of the contact surface viewed from the tape width direction may be raised perpendicular to the tape surface or 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 with different inclinations, the straight line and the curved line are continuously or indeterminate. It may be a composite wire connected continuously. Further, the contact line or the straight line constituting part or all of the contact surface 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 sides of the tape body, and the protrusions on both sides are at least partially in contact with other protrusions adjacent in the longitudinal direction of the tape, the bent spacer tape is bent between the protrusions on the outside. Although a gap is generated, it is possible to eliminate this gap by elastic restoration of the protrusion.
[0046]
That is, the protrusions on both sides are formed such that adjacent protrusions come into surface contact with each other when the spacer tape is unfolded, and the adjacent protrusions overlap each other when viewed from the thickness direction of the tape. When the spacer tape is pressed and elastically deformed, when the spacer tape is bent in the 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 projections on at least a part of both sides of the tape main body so as to be in contact with other projections adjacent to the longitudinal direction of the tape, injection molding with the tape main body as a part of the molding die or injection with the projections as a part of the molding die. In addition to this, other methods such as bonding, fusion, welding, welding, crimping, fitting, etc., can be adopted. .
[0048]
By the way, the first tape and the second tape of the present invention are either continuous in the longitudinal direction or intermittent in the longitudinal direction for positioning grooves for positioning the tab tape on the protrusions formed on both side edges of one side of the tape body. The tab tape is preferably formed so that the tab tape can be easily installed on the spacer tape, and misalignment is less likely to occur.
[0049]
In addition, the first tape and the second tape of the present invention may be provided with a full length wound around a reel, but the tape body and the protrusion are formed in a block having a predetermined length as necessary. A spacer tape having a required length may be obtained by adding each block.
[0050]
The blocks may be connected to each other using, for example, a separate member such as steeple, adhesive tape, adhesive tape, or a connecting means for connecting the blocks to both ends of each block in the longitudinal direction of the tape. For example, you may comprise so that a male and female fitting type connection means may be provided.
[0051]
In this way, 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 reel diameter. Spacer tapes with different lengths can be obtained, and many types of spacer tapes with different lengths corresponding to the difference in reel diameter can be manufactured and stored, so one type or a few types of blocks can be manufactured, The product inventory can be reduced, and there is an advantage that material costs and storage costs can be reduced.
[0061]
DETAILED DESCRIPTION OF THE INVENTION
Examples of the present invention will be specifically described below with reference to the drawings. However, the present invention is not limited to these examples.
[0062]
In the drawings, FIG. 1 is a perspective view of a spacer tape according to an 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 of the tape body 1. The protrusion 2 is provided.
[0063]
The protrusion 2 has a horseshoe-shaped tunnel shape in which both side edges of a single synthetic resin tape raw material are raised on the front surface side of the tape body 1 by, for example, heating roll molding, and the cross-sectional shape is opened on the back surface side of the tape body 1. Formed.
[0064]
When this spacer tape is wound on a reel together with a tab tape carrying an electronic component, the protrusion 2 is elastically deformed so as to become lower in the tape thickness direction and wider in the tape width direction, so that from the tape body 1 to the top of the protrusion 2 The height in the natural state, i.e., the state in which the tape body 1 is unfolded, is designed in anticipation of a decrease due to this elastic deformation.
[0065]
According to this spacer tape, since the protrusions 2 are continuous in the longitudinal direction of the tape, there is no possibility of a gap opening between the protrusions 2 in the longitudinal direction of the tape, and the protrusions 2 of the spacer tape wound outside. It is possible to reliably prevent the tab tape and the spacer tape from being deformed even if there is a deviation in the tape longitudinal direction between the projection 2 and the projection 2 wound inside.
[0066]
As a result, according to this spacer tape, the electronic component is scratched due to contact between the spacer tape and the electronic component, or the lead of the electronic component is deformed due to elastic deformation or plastic deformation of the tab tape or spacer tape. The effect that it is possible to reliably prevent the occurrence of defective electronic components before the feeding process and the effect that the generation of defective substrates due to the mounting of defective electronic components in the component mounting process can be reliably prevented can be obtained.
[0067]
In addition, according to this spacer tape, it is possible to reliably prevent the tab tape from being plastically deformed and the electronic components from moving with respect to the tab tape or the electronic components held by the tab tape from being misaligned in the longitudinal direction of the tape. Thus, it is possible to improve the locating accuracy in the component mounting process and to reliably prevent the occurrence of a defective substrate due to the locating failure.
[0068]
  FIG. 2 shows an example of the embodiment shown in FIG.Reference exampleAs shown in FIG.Reference exampleThe tube-shaped protrusion 2 is formed by providing portions 2a that are folded back from both sides of the tunnel-shaped protrusion 2 of the previous example so as to close the open surface of the tunnel-shaped by the same manufacturing method.
[0069]
  thisReference exampleAccording to the above, it is possible to reliably prevent one of the protrusions 2 wound inward and outward from being pushed into the other protrusion 2 from the open surface of the other protrusion 2, and the interval between the wound tape bodies 1 can be reduced. Since it can be held accurately, it is possible to more reliably prevent defective electronic components from being generated before the component mounting and feeding process due to scratches on the electronic components or deformation of the lead of the electronic components, and component mounting The effect that generation | occurrence | production of the defective board | substrate by mounting of the defective components in a process can be prevented more reliably can be acquired.
[0070]
  In addition, thisReference exampleIn order to more reliably prevent one of the protrusions 2 wound inside and outside from entering the other, the portion folded from the protrusion 2 and the tape body are viewed in the tape width direction when viewed from the tape thickness direction. However, it does not have to be overlapped in this way.
[0071]
  Also thisReference exampleThen, in order to avoid cost increase, the overlapped portions are simply overlapped. However, if the overlapped portions are fixed to each other by, for example, adhesion, fusion, welding, adhesion, etc., they are wound inward and outward. It is possible to more reliably prevent one of the stacked protrusions 2 from entering the other.
[0072]
  FIG. 3 shows another embodiment of the present invention.Reference example1 is a perspective view of a spacer tape according to the present invention, and this spacer tape is obtained by molding a single synthetic resin tape with a heating roller, and has a tape body 1 formed in an extended surface and tape bodies on both side edges thereof. 1 is provided with protrusions 2 that protrude evenly on both sides of the tape 1 and are continuous over the entire length in the longitudinal direction of the tape.
[0073]
The cross-sectional shape of the protrusion 2 is circular, and when the spacer tape is bent in the tape thickness direction so that the neutral axis of the tape body 1 coincides with the neutral axis of the protrusion 2 when viewed from the tape width direction, the tape body No tension or pressure is applied to 1.
[0074]
  thisReference exampleThen, the tape body 1 and the protrusion 2 are formed of the same material. For example, the tape body 1 is formed of an extrusion molding material of synthetic resin such as polyetherimide, polyimide, polyethylene triphthalate, and the protrusion 2 is formed of, for example, You may form with a tape main body 1 and a different extrusion (coextrusion) molding material, such as a synthetic rubber. When the tape body 1 and the protrusion 2 are made of different materials, they may be separately molded and joined by bonding, fusing, welding, forging, crimping, etc., for example, by simultaneous extrusion (coextrusion) You may shape | mold simultaneously.
[0075]
  thisReference exampleSince the operations and effects are the same as those of the embodiment of the present invention shown in FIG.
[0076]
  FIG. 4 shows the reference example shown in FIG.Further reference examplesFIG. 4 is a partially exploded perspective view showing the spacer tape according to FIG.Reference examplesIn FIG. 4, the tape body 1 and the protrusion 2 are formed of the same material.Reference exampleIn this case, 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 protrusion 2 is formed of an extrusion molding material that is different from the tape body 1 such as synthetic rubber.
[0077]
The cross-sectional shape of the protrusion 2 is substantially circular, and includes a tape insertion groove 2b that is recessed from one place on the peripheral surface to the center.
[0078]
Here, both side edges in the longitudinal direction of the tape body 1 are respectively inserted into the tape insertion grooves 2b of the protrusions 2, and if necessary, the tape body 1 and the protrusions 2 are joined so as not to be disassembled by, for example, adhesion or fusion. However, the tape main body 1 and the protrusion 2 may be simply fitted together, and the tape main body 1 and the protrusion 2 may be disassembled after use.
[0079]
When the tape body 1 and the protrusion 2 are made of different materials as described above, the tape body 1 and the protrusion 2 can be simultaneously formed by, for example, simultaneous extrusion (coextrusion).
[0080]
  Of course, thisReference exampleOther configurations, operations, and effects are the same as those in the above-described embodiments, and thus are omitted.
[0081]
  By the way, thisReference exampleThe side edge of the tab tape can be inserted into the tape insertion groove 2b of the protrusion 2 in place of the tape body 1 of the spacer tape, and the protrusion 2 can be used as a tab tape spacer.
[0082]
In this case, the protrusion 2 and the tab tape may be joined in an inseparable manner by bonding, fusing or the like. However, the tab tape and the protrusion (tab tape spacer) 2 are disassembled after use by fitting them so that they can be disassembled. It is preferable that each can be reused as much as possible.
[0083]
When the projection 2 is used as a tab tape spacer in this way, both side edges of the tab tape are respectively inserted into the tape insertion grooves 2b of the projection (tab tape spacer) 2 and wound around the reels. 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 components and the tab tape from rubbing against 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 electronic component from being defective due to winding of the tab tape around the reel, that is, reeling.
[0084]
In addition, since there is no possibility that a gap is generated in the longitudinal direction of the strip, there is no possibility that the tab tape is locally deformed by fitting the strip wound on the outer side into the gap between the strips wound on the inner side. As a result of improving the location accuracy in the longitudinal direction of the tab tape, it is possible to prevent generation of a defective substrate due to location failure.

Each of the positioning grooves 2d is formed in an inverted V-shaped cross section.
[0086]
As a result, the positioning protrusion 2c of the inner spacer tape is fitted into the positioning groove 2d of the spacer tape that is wound outward when the reel tape is wound, and the position of the spacer tape in the tab tape width direction that is wound inward and outward Is controlled to be constant, so that the location accuracy in the component mounting process can be increased, and the distance between the tape main body 1 of the spacer tape is accurately maintained constant to ensure the contact between the tape main body 1 and the electronic component.

  FIG. 10 is also different from the embodiment shown in FIG.Reference exampleIt is a perspective view of this, as shown in FIG.Reference exampleThen, a positioning groove 2g for restricting the position of the tab tape in the width direction is formed on the front surface side of each protrusion 2, and the cross-sectional shape of each protrusion 2 is formed in a crescent shape having a concave groove 2h on the back surface side.
[0099]
  thisReference exampleAlthough the shape of the concave groove 2h is a partial circular groove shape having the same diameter as the diameter of each projection 2, the concave groove 2c may be formed by a partial arc groove having a larger diameter than that of the projection 2 but may have a smaller diameter. Or a square groove such as a trapezoidal groove.
[0100]
  Thus, when the groove 2h is provided on one side of each protrusion 2, when the spacer tape is wound, the groove 2h of the spacer tape wound outwardly meshes with the top of the spacer tape wound inside. The spacer tape that overlaps inside and outside comes to be located at the same position in the tape width direction, so that the location accuracy in the tape width direction in the component mounting process can be improved, and the interval between the tape bodies 1 wound inside and outside is constant. It is possible to reliably prevent the tape body 1 from coming into contact with the electronic component. In addition, the groove width of the reel can be reduced, and dust can be prevented from being generated due to contact of the side edge of the spacer tape with the flange of the reel.
The other structure, operation, and effect of this embodiment are shown in FIG.Reference exampleSince it is the same as that, it abbreviate | omits.

  FIG. 11 is further different from the embodiment shown in FIG.Reference exampleIs a perspective view of the spacer tape according to FIG.Reference exampleThen, the top surface 2i and the bottom surface 2j of each projection 2 are formed in a plane parallel to the surface of the tape body 1, and positioning grooves 2g for positioning the tab tape in the tape width direction are formed on both front and back sides of each projection 2. .
[0102]
  thisReference exampleAccording to the present invention, when the spacer tape is wound, even if the inner and outer spacer tapes are displaced in the tape width direction, the bottom surface 2j of the spacer tape wound outside is received by the top surface 2i of the spacer tape wound inside. By being stopped, the interval in the tape thickness direction of the tape body 1 is kept constant, and the tape body 1 can be reliably prevented from coming into contact with the electronic component.

[0104]
FIG. 12 is a side view of a spacer tape according to another embodiment of the present invention. In this embodiment, a large number of protrusions 2 are arranged in the tape longitudinal direction on the tape surface side, and the tape body 1 is Adjacent protrusions 2 are provided so as to contact each other when deployed. The protrusion 2 is fixed to the tape body 1 by, for example, an insert molding method or an injection molding method.
[0105]
According to this embodiment, when the tape body 1 is wound around the reel so as to be bent toward 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. There is no gap extending between the two in the longitudinal direction of the tape. Actually, a minute gap is formed, but this gap can be ignored in terms of function compared to the length of the protrusion 2 in the tape longitudinal direction. For this reason, there is no possibility that the spacer tape protrusion 2 wound outside will fit between the spacer tape protrusions 2 wound inside.
[0106]
In addition, if an external force that bends the spacer tape to the surface side acts on the surface where the protrusions 2 are in contact, the protrusions 2 of the spacer tape will stick together and will not bend from the unfolded state to the surface side. There is no risk of the tape protrusion 2 entering between the spacer tape protrusions 2 wound inward, and the spacer tape protrusion 2 wound outward is between the spacer tape protrusions 2 wound inward. The risk of local deformation of the spacer tape and the tab tape is reliably eliminated by the entry.
[0107]
Other configurations, operations, and effects of this embodiment are the same as those of the above-described embodiments, and thus are omitted.
[0108]
FIG. 13 is a side view of a modified spacer tape shown in FIG. 11 according to another embodiment of the present invention. The spacer tape shown in FIG. 8 has adjacent protrusions 2 (A), 2 (V ) Is in surface contact over the front height.
[0109]
That is, this spacer tape is formed by alternately arranging A-shaped protrusions 2 (A) and V-shaped protrusions 2 (V) on both surfaces of the tape body 1 in the longitudinal direction of the tape, and these A-shaped protrusions 2 (A). And the V-shaped protrusion 2 (V) are formed at the same height, and although not particularly limited, the length La of the A-shaped protrusion 2 (A) in the tape longitudinal direction and the V-shaped protrusion 2 (V) The length Lv in the tape longitudinal direction is made equal.
[0110]
Here, the A-shaped protrusion 2 (A) is a shape in which the longitudinal dimension of the protrusion 2 (A) decreases continuously and / or stepwise toward the top of the protrusion 2 (A), or The protrusion 2 (A) has a uniform shape in the longitudinal direction, that is, a tapered or rectangular protrusion 2 (A). A curved surface is used.
[0111]
Further, the V-shaped protrusion 2 (V) means that the longitudinal dimension of the protrusion 2 (V) contacting the surface of the tape body 1 is continuously and / or stepwise toward the top of the protrusion 2 (V). Or a shape having a uniform longitudinal dimension of the protrusion 2 (V), that is, a protrusion 2 (V) having a flared shape or a rectangular shape in a side view, Both ends of the tape in the longitudinal direction are formed as convex curved surfaces corresponding to the concave curved surface of the A-shaped projection 2 (A), and the tape is so that the A-shaped projection 2 (A) and the V-shaped projection 2 (V) are in contact with 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 protrusion 2 (A) and the V-shaped protrusion 2 (V) is formed as a curved surface that is convex toward the A-shaped protrusion 2 (A). However, it may be formed in a curved surface convex toward the V-shaped protrusion 2 (V), or may be formed in a plane inclined to the surface of the tape main body 1 and further orthogonal 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 abutment surface is formed in parallel with the tape width direction, but may be inclined in the tarp width direction, and may be curved, for example, in an arc shape or S shape in the tape thickness direction. It may be bent into a letter shape or a crank shape.
[0113]
The A-shaped protrusion 2 (A) and the B-shaped protrusion 2 (B) are made of, for example, an elastic body such as a synthetic rubber. When the spacer tape is bent, the A-shaped protrusion 2 (A) and the B-shaped protrusion 2 (B) are outside the bent protrusions 2 (A) and 2 (V). Although a widening gap is generated, the protrusions 2 (A) and 2 (V) on the inner side of the bend are brought into 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]
As a result, the spacer tape protrusions 2 (A) and 2 (V) wound outside are not likely to fit between the spacer tape protrusions 2 (A) and 2 (V) wound inside, The spacer tape protrusions 2 (A) and 2 (V) wound inside may be fitted between the spacer tape protrusions 2 (A) and 2 (V) wound inside to deform the spacer tape and the tab tape. Also disappear.
[0115]
Of course, the protrusions 2 (A) and 2 (V) on the inner side of the bend may be formed without causing the protrusions 2 (A) and 2 (V) on the outer side of the bend to be elastically restored and continuous. 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) arranged alternately on both sides in the longitudinal direction of the tape. V-shaped protrusions 2 (V), and these protrusions 2 (A) so that the edge of the A-shaped protrusion 2 (A) and the edge of the V-shaped protrusion 2 (V) are continuous when viewed in the tape thickness direction. 2 (V).
[0117]
The length Lg of the gap in the tape longitudinal direction may be designed empirically. For example, the length Lg of the top surface of the A-shaped projection 2 (A) or the top ridge line in the tape longitudinal direction la (la / 2) The following is preferable, and in this embodiment, it is designed to be 1/4 (la / 4) with respect to the length la in the tape longitudinal direction of the top surface or the top ridge line of the A-shaped protrusion 2 (A). Yes.
[0118]
  Thus, when the A-shaped protrusions 2 (A) and the V-shaped protrusions 2 (V) are alternately arranged in the tape longitudinal direction,FIG.As shown in the side view, external force P is applied from the outside to a point T where the edges of the outer V-shaped protrusion 2 (V) and the inner V-shaped protrusion 2 (V) are abutted when the spacer tape is wound around the reel. When this occurs, the V-shaped protrusion 2 (V) indicated by the outer hatching is likely to be pushed between the inner protrusions 2 (A) and 2 (V) adjacent to the left and right with the T point interposed therebetween.
[0119]
  But in this case,FIG.For example, the V-shaped protrusion 2 (V), the V-shaped protrusion 2 (V) on the surface side, the left-side inner side from the T point, and the A-shaped protrusion 2 (A) on the surface side, as shown exaggeratedly in FIG. The A-shaped protrusions 2 (A) on both the front and back surfaces on the right outer side, the V-shaped protrusions 2 (V) on the right inner surface side, and the tape body 1 are elastically deformed.
[0120]
  FIG.In FIG. 3, the tape body 1 and the back surface (core side) protrusions 2 (A) and 2 (V) of the inner spacer tape are shown not to be elastically deformed. It gradually elastically deforms from the outside toward the inside.
[0121]
In this way, since the external force P is distributed and received by the plurality of spacer tapes, the external force received by the outer spacer tape is reduced, and the deformation thereof is moderately reduced. Therefore, the outer tape body 1 is plastic. There is no deformation. Further, since the deformation amount of the outer tape body 1 in the tape thickness direction is small, the outer tape body 1 is not rubbed against the electronic component.
[0122]
Further, when the external force P is removed, the V-shaped protrusion 2 (V), the surface-side V-shaped protrusion 2 (V), the left inner side from the point T, the surface-side A-shaped protrusion 2 (A), the right outer side Since the tape body 1 is pushed back to the 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, the location accuracy is not impaired.
[0123]
Of course, the distance Lg between the A-shaped protrusion 2 (A) and the V-shaped protrusion 2 (V) is set to a quarter of the length La of the top surface or the top ridge line of the A-shaped protrusion 2 (A). The protrusions 2 (A) and 2 (V) of the outer spacer tape do not step on the inner protrusions 2 (A) and 2 (V). As described above, the position of the tape main body 1 when the external force P is lost. Is returned to the normal position, and a precisely uniform interval is placed between the tape bodies 1 wound inside and outside.
[0124]

The effect that it can be completely eliminated can be obtained.
[0125]
This action can prevent local bending of the spacer tape, and the local bending of the spacer tape can prevent the electronic component from being scratched and the deformation of the lead of the electronic component. It is possible to obtain an effect that it is possible to prevent occurrence of defective electronic components before.
[0126]
In addition, the above action can prevent the tab tape from being bent locally together with the spacer tape, and the local bending of the tab tape can prevent the electronic component from moving with respect to the tab tape. The effect that it can raise can be acquired.
[0127]
  The second tape of the present invention is a spacer tape comprising protrusions projecting on one or both of the front and back sides of the tape body on both side edges of the tape body, and at least a part of the protrusions adjacent in the tape length direction is one or both of the front and back surfaces. Both are in contact with each otherThe protrusions adjacent to each other are formed so as to come into surface contact with each other when the spacer tape is unfolded, and the contact surfaces of the adjacent protrusions overlap each other when viewed from the tape thickness direction.Therefore, the spacer tape can be wound around the reel so that there is no gap between the protrusions on the front or back side of the spacer tape, and the protrusion of the spacer tape wound on the outer side of the spacer tape is wound on the inner side. It is possible to obtain an effect that the fitting between the protrusions can be completely eliminated.
[0128]
This action can prevent local bending of the spacer tape, and the local bending of the spacer tape can prevent the electronic component from being scratched and the deformation of the lead of the electronic component. It is possible to obtain an effect that it is possible to prevent occurrence of defective electronic components before.
[0129]
In addition, the above action can prevent the tab tape from being bent locally together with the spacer tape, and the local bending of the tab tape can prevent the electronic component from moving with respect to the tab tape. The effect that it can raise can be acquired.
[0132]
In addition, since there is no possibility that a gap is generated in the longitudinal direction in the strip, there is no possibility that the strip wound around the outside fits into the gap in the inner strip and the tab tape is not locally deformed. By this action, there is no possibility that the position of the electronic component in the tab tape longitudinal direction will fluctuate, and the location accuracy in the tab tape longitudinal direction in the component mounting process can be improved, resulting in the generation of defective substrates due to location defects. The effect that can be prevented can be obtained.
