Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a tab tape reel, and in particular, between a pair of flanges, the interval between the outer periphery of the core and the interval between the flange ends (near the outer peripheral end of the flange) are matched as much as possible to improve the accuracy and ship. In order to improve the accuracy by removing the deformation of the flange end when loading to the mounting machine, or to improve the accuracy, the reel may deform, wavy or move with respect to the tab tape when winding and unwinding the tab tape The present invention relates to a tab tape reel which reliably prevents the occurrence of a tape reel and significantly improves the accuracy of the reel.
[0002]
[Prior art]
Conventionally, the tab tape reel has a core around which the tab tape is wound, and a disc-shaped reel fixed to both ends in the axial direction of the core in order to limit the position in the width direction of the tab tape wound around the core within a certain range. And a pair of flanges.
[0003]
[Problems to be solved by the invention]
In this conventional tab tape reel, the difference between the interval near the outer periphery of the core and the interval between the flange ends (near the outer peripheral end of the flange) is determined as a measure for determining accuracy, but the flange end of the reel is released. Because the distance between the flange ends widens during loading and mounting on a mounting machine, accuracy decreases.In addition, if the distance between the flanges increases, bulkiness increases in the axial direction when packing, so logistics costs are reduced. Even the problem of increase is derived.
[0004]
Further, in this conventional tab tape reel, when winding the tab tape, or when feeding the tab tape, the reel is deformed, wavy or moved in the axial direction with respect to the tab tape, that is, in the width direction of the tab tape. Of the reel and the flange of the reel may strongly rub against each other.
[0005]
If the tab tape and the flange are strongly rubbed, the resistance to winding and unwinding will increase, making smooth winding and unwinding impossible.In addition, wear debris on the tab tape and flange will be generated, and there will be problems such as adhesion to electronic components as foreign matter. Is caused.
[0006]
Further, if the reel is deformed, wavy, or moved in the axial direction with respect to the tab tape during winding or unwinding of the tab tape, the position of the tab tape in the width direction is not stabilized in the mounting process, which causes a problem that the location accuracy is reduced. become.
[0007]
In particular, since the conventional tab tape reel has a structure in which a pair of flanges are connected by a core, if the tab tape is strongly rubbed against the flange at a position away from the core, the flange is pushed outward and the flange is pushed out. , The position of the tab tape in the width direction fluctuates or undulates more widely.
[0008]
The present invention solves such a problem of the prior art and improves the accuracy by making the interval between the outer periphery of the core and the interval between the flange ends (near the outer peripheral end of the flange) as close as possible between a pair of flanges. Planning, loading at the time of shipping, improving the accuracy by eliminating the deformation of the flange end when mounting it on the mounting machine, and the reel deforming, waving or An object of the present invention is to provide a tab tape reel in which movement is reliably prevented and the accuracy of the reel is significantly improved.
[0009]
[Means for Solving the Problems]
In order to achieve this object, the tab tape reel of the present invention is a tab tape reel including a core around which a tab tape is wound, and a pair of flanges for regulating a position in a width direction of the tab tape wound around the core. The technical means that the core is rotatably provided on one or both flanges is adopted.
[0010]
According to the tab tape reel of the present invention, in a state where the flange and the core are fixed in the axial direction by fixing the flange, the tab tape can be wound around the core by configuring the core to be rotatable or wound around the core. The tab tape can be fed out, so the reel and its flange are securely prevented from deforming, waving or moving in the axial direction when winding or feeding the tab tape, and the tab tape is strongly rubbed against the flange. Can be prevented.
[0011]
As a result, the resistance to winding and unwinding of the tab tape is reduced, so that the winding and unwinding of the tab tape can be performed smoothly, and the generation of wear debris between the tab tape and the flange can be extremely reduced. In addition, the contamination of the electronic components mounted on the tab tape with foreign substances (contamination) is almost eliminated.
[0012]
Further, when the tab tape is wound by rotating the core while fixing the flange, the reel and its flange are not deformed, wavy or moved in the axial direction, and the flange is not pushed by the tab tape. As a result, there is no fear that the flange interval is widened. As a result, the positional accuracy of the tab tape in the width direction is significantly increased, and the positional accuracy in the component mounting process can be increased.
[0013]
In the tab tape reel of the present invention, the flange and the core may be formed so as not to be disassembled, or the flange and the core may be formed so as to be disassembled.
[0014]
Hereinafter, the tab tape reel of the present invention will be described in more detail.
The core of the present invention may be provided rotatably with respect to one flange, or may be provided rotatably with respect to both flanges.
[0015]
When the core is rotatably provided to one of the flanges, one of the rotatable flanges is fixed to the core, and the other flange and the core are rotated to wind or unwind the tab tape. I can do it.
[0016]
If the core is provided rotatable with respect to both flanges, the tab tape may be wound or unwound by fixing one of the flanges and rotating the core. The tab tape may be wound or unwound by rotating only the core while fixing the flange.
[0017]
In this case, the core and the flange rotatable with respect to the core are structurally formed separately from each other, and are assembled rotatably with respect to each other by, for example, fitting.
[0018]
As a structure in which the separately formed core and flange are rotatably assembled to each other, a structure that cannot be easily disassembled can be employed, but the core and flange are easily disassembled. When a structure that can be used is adopted, it is possible to reduce distribution costs such as transport costs and storage costs of empty reels for reuse or disposal and further recycling.
[0019]
Specifically, although not particularly limited, for example, a shaft having a smaller diameter, or an equal diameter, or a larger diameter than the main body is continuously provided on both sides of the main body of the core around which the tab tape is wound, and the core is adapted to this shaft. A basic structure can be adopted in which a bearing hole is formed in each flange, and each shaft is inserted into the bearing hole of the corresponding flange.
[0020]
In this basic structure, for example, a concave groove such as a V-shaped groove, a U-shaped groove, a single-flow trapezoidal groove, an equal leg trapezoidal groove, a square groove, etc. is formed on one of the peripheral surface of the shaft and the peripheral surface of the bearing hole, and the other side. By forming a projection or a ridge that bites into the concave groove and fitting the shaft into the bearing hole so that the concave groove and the projection or the ridge mesh with each other, the axial positioning of the core with respect to the flange can be reliably performed. preferable.
[0021]
It is also possible to assemble the two flanges and the core so that they cannot be easily disassembled.For example, if at least a groove is provided on the shaft of the core, the diameter of the shaft is reduced and the flange and the core are easily disassembled. And can be easily assembled.
[0022]
Here, for example, only one kind of the dimensions of the shaft and the bearing hole is set so that a plurality of types of cores having different outer diameters and shaft lengths and a flange having a different outer diameter can be freely rearranged. The optimum core and flange can be selected and combined according to the width, thickness and length of the electronic component to be mounted, and the width, thickness, and length of the tab tape can be adjusted. This is preferable because it is not necessary to manufacture or store various types of reels corresponding to the shape and size of the parts.
[0023]
Of course, it is also possible to modularize the core and the flange by setting a plurality of types in which the dimensions of the shaft and the bearing hole are standardized.
[0024]
In the tab tape reel of the present invention, one or both of the flanges are fixed at the time of winding or feeding, so that the problem that the interval between the flanges widens at the peripheral portion does not essentially occur, Is provided rotatably with respect to both flanges, in order to further reliably prevent the flanges from widening, at least one of the first and second flanges for connecting the pair of flanges at a position away from the core is provided. Preferably, two bridges are provided.
[0025]
The bridge portion may be provided, for example, so as to maintain a constant interval between the outer peripheral edges of the two flanges, and may be provided so as to connect a part of the outer peripheral edge of the two flanges to the center side to some extent. In this case, since the outer diameter of the flanges is reduced, it is more preferable to provide the outer peripheral edges of both flanges so as to connect them.
[0026]
Further, the bridge portion may be provided at a plurality of positions at a predetermined angle around the outer periphery of the core, and the bridge portion is formed in a circumferential direction of the flange except for a portion necessary for winding and feeding out the tab tape. May be provided.
[0027]
If the bridge part is provided in a series in the circumferential direction of the flange except for the part necessary for winding and feeding the tab tape, the part without the bridge part is opened and closed with a lid, or the bridge part is extended after winding After the tab tape has been wound up, dust, moisture, etc. may be wound around the reel during transport or storage before unwinding. It is preferable to reliably prevent intrusion between the attached tab tapes.
[0028]
Further, the bridge portion may be attached to the flange before winding the tab tape around the reel, or may be attached to the flange after winding the tab tape around the reel. Of course, it is also possible to form this bridge part integrally with one of the flanges, or to divide it into two parts in the axial direction, for example, and to form each part as one with the corresponding flange.
[0029]
In addition, in the present invention, if necessary, a slip sheet rich in surface smoothness is provided inside the flange, and the position of the side edge of the tab tape is regulated by the flange via this slip sheet, so that the tab tape is formed. Can be further smoothly wound and unwound, the generation of wear debris of the tab tape can be further reduced, and the wear debris of the flange can be completely eliminated.
[0030]
[Action]
As described above, the present invention relates to a tab tape reel including a core around which a tab tape is wound, and a pair of flanges for regulating a position in a width direction of the tab tape wound around the core. Is provided rotatably with respect to one or both flanges, so that one or both flanges are fixed, and the core is rotated to take up the tab tape on the reel or to feed the tab tape from the reel. As a result, it is possible to obtain an effect that it is possible to reliably prevent the reel from being axially deformed, wavy, or moved with respect to the tab tape during winding and unwinding of the tab tape.
[0031]
By the way, in the tab tape reel, the difference between the interval between the outer periphery of the core and the interval between the flange ends (near the outer peripheral end of the flange) between a pair of flanges is determined as a measure for determining the accuracy. In the tab tape reel of (1), since the bridge portion is provided on the flange, there is no difference between the interval near the outer periphery of the core and the interval between the flange ends (near the outer peripheral end of the flange), or the function of minimizing the difference is minimized. .
[0032]
Further, in the tab tape reel of the present invention, as described above, there is no difference between the interval between the outer periphery of the core and the interval between the flange ends (near the outer peripheral end of the flange) between the pair of flanges, or the difference is minimized. Therefore, the spacing between the flange ends does not widen when loading or mounting to a mounting machine at the time of shipment, and it is possible to improve accuracy, and especially, when winding or feeding out the tab tape, the tab tape is used. On the other hand, as a result of the reel not being deformed, wavy or moved in the axial direction, the position in the width direction of the tab tape is stabilized in the mounting process, and the location accuracy is improved.
[0033]
Further, in the tab tape reel of the present invention, when the tab tape is wound or when the tab tape is unreeled, the reel does not deform, wavy or move in the axial direction with respect to the tab tape, that is, in the width direction of the tab tape. This has the effect of preventing the edge and the flange of the reel from strongly rubbing each other.
[0034]
In addition, in the tab tape reel of the present invention, the tab tape and the flange hardly rub against each other, so that the resistance to winding and unwinding is small, smooth winding and unwinding can be performed, and wear debris of the tab tape and the flange is generated. It has the effect of disappearing.

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.
[0036]
FIG. 1 is a perspective view of a tab tape reel according to one embodiment of the present invention. As shown in FIG. 1, the tab tape reel has a core 1 around which a tab tape is wound, and both ends of the core 1 in the axial direction. A pair of disk-shaped flanges 2 supported by the section, and bridge sections 3 provided at a plurality of locations around the outer periphery of the core 1 at a predetermined angle, for example, 45 degrees.
[0037]
FIG. 2 is a front view of the core 1. In FIG. 2, a horizontal dashed line indicates a rotation axis of the core 1, and a vertical dashed line indicates a center line in the tab tape width direction. The right side from the center line shows the appearance as viewed from the front, and the left side shows a longitudinal front view. FIG. 3 is a side view of the tab tape reel. In FIG. 3, the upper portion of the front flange is partially cut away.
[0038]
As shown in FIGS. 2 and 3, the core 1 includes a main body 4 around which a tab tape is wound, a shaft 5 composed of circular shafts connected to both ends of the main body 4, and an entire length in the axial direction. The shaft 5 is formed of a hollow body having one formed sliding groove 6, and a concave groove 7 formed of a trapezoidal groove is formed on the outer peripheral surface of the shaft 5 over the entire circumference.
[0039]
The cross-sectional shape of the hollow portion of the core 1 is actually formed into a shape corresponding to the cross-sectional shape of the shaft inserted into the core 1 at the time of winding, for example, a non-circular shape such as a square or a wheel wheel. It is illustrated by a simple circle.
[0040]
By the way, a bearing hole 8 composed of a circular hole corresponding to the shaft 5 is formed at the center of each flange 2, and by forming corners on both sides of the periphery of the bearing hole 8, the periphery of the bearing hole 8 is formed. Are formed on the ridge of a trapezoidal cross section of an equal leg corresponding to the concave groove 7 of the core 1.
[0041]
When the end of the core 1 is pressed against the position of the bearing hole 8 of each flange 7 and the flange 7 is pressed against the core 1 with a certain force or more, the core 1 is reduced in diameter and the shaft 5 is easily inserted into the bearing hole 8. storm in. When each of the flanges 2 is pushed to the position of the concave groove 7, the core 1 is elastically restored and the concave groove 7 and the bearing hole 8 are engaged with each other, whereby the two flanges 2 are separated from each other by a predetermined distance W1. It is rotatably supported.
[0042]
As shown in FIG. 3, a dovetail-shaped recess 9 is formed on the outer peripheral edge of each of the flanges 2 at every 45 degrees around the outside of the core 1, and the bridge portion formed in this recess 9 in a dovetail shape is provided. 3 is fitted. As shown in FIG. 2, an inverted groove-shaped recess 10 is formed at the end of each bridge portion 3 so as to engage with the flange 2. By incorporating the bottom portion of the flange 9, the peripheral edges of both flanges 2 are held by the bridge portion 3 at a predetermined interval W3.
[0043]
When the end of the tab tape is inserted into the slot 6 which is opened on the peripheral surface of the main body 4 of the core 1, the flange 2 is fixed and the core 1 is rotated. Can be wound. Further, when the flange 2 is fixed and the tab tape wound around the core 1 is pulled out, the tab tape is fed out from the reel while rotating the core 1.
[0044]
In this manner, when winding and feeding are performed with both flanges 2 fixed, the reel can be reliably prevented from deforming, waving or moving with respect to the tab tape, and the tab tape is strongly rubbed against the flange 2 at that time. It will not be done.
[0045]
As a result, the resistance to winding and unwinding is reduced, so that winding and unwinding can be performed smoothly, and wear debris of the tab tape and the flange 2 hardly occurs, and foreign matter on the electronic components mounted on the tab tape is reduced. Adhesion can be almost completely eliminated.
[0046]
Further, when winding and feeding are performed with both flanges 2 fixed, the reel does not deform, wavy or move in the axial direction with respect to the tab tape at that time, so that the positional accuracy of the tab tape in the width direction is remarkably improved. And the location accuracy of electronic components in the component mounting process has been dramatically improved.
[0047]
Further, since the peripheral portions of the two flanges 2 are connected by the bridge portion 3, the interval between the peripheral portions of the both flange portions 2 is surely kept constant, and even if a large number of reels are stacked in the axial direction during packing, the bulk is increased. It is possible to reduce the logistics cost by reducing the packing style without increasing extra.
[0048]
The reel that has been emptied by feeding out the tab tape is disassembled into the bridge portion 3, the flange 2 and the core 1 as it is or in order to reduce distribution costs, and is reused or recycled as much as possible.
[0049]
Here, each of the bridge portions 3 can be easily detached and disassembled from the flange 2 by pulling the bridge portion 3 outward in the radial direction with a certain force or more. The core 1 can be easily disassembled by separating the core 1 with a force greater than a certain value in the axial direction.
[0050]
In addition, the inner surface of each of the bridge portions 3 and both end edges in the circumferential direction are formed in a smoothly continuous curved surface so that the tab tape and the electronic components mounted thereon are not caught by the bridge portion 3. .
[0051]
Further, although the flange 2 of this embodiment is formed in an elongated plate shape, an opening may be provided as appropriate in order to reduce the weight and observe the winding state of the tab tape. This opening is preferably closed with a transparent or translucent glass or synthetic resin, especially a transparent synthetic resin such as acrylic resin, in order to prevent foreign substances such as dust from entering the inside.
[0052]
In addition, in order to prevent the surface distortion of the flange 2, a rib may be appropriately provided on the outer surface of the flange 2, and the periphery of the bearing hole 8 and the peripheral portion of the flange may be formed thick.
