[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a carrier tape winding method and a winding device for holding an electronic component such as an integrated circuit (IC) on a carrier tape and winding the carrier tape on a reel. .

[0002]

2. Description of the Related Art FIG. 6 is a perspective view of a carrier tape T holding an electronic component. The carrier tape T is composed of an embossed tape Ta and a cover tape Tb. The embossed tape Ta has concave portions 1 at a constant pitch.
Are formed. A feed hole (perforation) 2 having a constant pitch is formed in one edge of the embossed tape Ta.

An electronic component W is housed in the recess 1. In the example of FIG. 6, the electronic component W is an integrated circuit (IC). After the electronic component W is stored in the recessed portion 1, the cover tape Tb is joined to the embossed tape Ta. The cover tape Tb is a thin and soft transparent or translucent film and has a sealant layer. The cover tape Tb is heat-welded to the embossed tape Tb on an extension of the line indicated by (a) and (b) in FIG. (Heat sealed). As a result, the opening of the recess 1 in which the electronic component W is stored is covered with the cover tape Tb. As described above, the electronic component W is housed in the recess 1 of the embossed tape Ta, and the cover tape T
The work of joining b by heat welding is performed using an automatic taping device or a semi-automatic taping device.

In this taping device, the embossed tape Ta is pulled out from the reel on the supply side, and the electronic component W is automatically inserted into each recess 1 of the embossed tape Ta.
The cover tape Tb is pulled out from a supply reel provided on a path different from that of the embossed tape Ta, joined to the embossed tape Tb containing the electronic component W, and in the heat sealing mechanism section, the embossed tape Ta and the cover tape. It is heat-welded with Tb. The carrier tape T, in which the electronic component W is housed in each recess 1 and the cover tape Tb is welded, is a reel R on the winding side as shown in FIG.
Is wound around the outer periphery of the core Rc. The reel R is made of paper or synthetic resin. The reel R on which the carrier tape T is wound is installed in an automatic mounting device (mounting device) that automatically mounts electronic components on a circuit board or the like. In this automatic mounting apparatus, the carrier tape T is pulled out from the reel R, the cover tape Tb is peeled from the embossed tape Ta, and the electronic component W in the recess 1 is taken out and automatically mounted on a circuit board or the like.

[0005]

In the above-described automatic taping device or semi-automatic taping device, when the carrier tape T is wound on the reel R on the winding side, conventionally, as shown in FIG. A portion where electronic parts are not accommodated is provided in the recessed portion 1, the winding start end is inserted into the slit Ra on the outer periphery of the core Rc of the reel R on the winding side, and in this state, the reel R on the winding side is rotated in the arrow direction. The carrier tape T in which the embossed tape Ta and the cover tape Tb are joined is wound up in sequence.

However, since the carrier tape T is a joined body of the embossed tape Ta and the cover tape Tb, it has a thickness as much as the concave portion 1 is formed. Therefore, it is difficult to insert the winding start end of the carrier tape T into the slit Ra on the outer periphery of the core Rc. First, since the carrier tape T has a thickness corresponding to the formation of the concave portion 1, in order to insert the carrier tape T into the slit Ra, the concave portion 1 is crushed at the winding start end to reduce the thickness. The work of inserting it into the slit Ra becomes necessary,
The work is very complicated. Since the embossed tape Ta is made of a fairly hard resin material and has elasticity, when the reel R starts to rotate after the winding start end is inserted into the slit Ra, the tape T is slit. Sometimes get out of the room, and as a result,
The tape T may not be reliably wound around the reel R in some cases.

Further, when the reel R is loaded into the automatic mounting apparatus, a pull-out section for pulling out the carrier tape T from the reel is required. In the conventional winding method and winding apparatus, the core of the reel R is used. After winding the carrier tape T containing the electronic component W in Rc by a predetermined number of turns, the carrier tape T not containing the electronic component W is wound around the outer peripheral portion several times, and the electronic component W is stored in the automatic mounting apparatus. The carrier tape T on the outer peripheral portion, which is not open, is used as a pull-out starting end. Further, when the reel is stored or transported, the electronic component is not stored in the carrier tape on the outer peripheral portion of the reel R, so that the electronic component can be protected.
However, the embossed tape Ta of the carrier tape T
Since it is expensive, it is uneconomical to wind the embossed tape Ta around the outer periphery without inserting the electronic parts for the purpose of pulling out by the automatic mounting device and for the purpose of protecting the electronic parts.

The present invention is to solve the above-mentioned conventional problems, and a method and a method for winding a carrier tape, in which a carrier tape holding an electronic component can be surely wound around a winding-side reel. The purpose is to provide a device.

Another object of the present invention is to provide a method and apparatus for winding a carrier tape, which can improve the uneconomicalness of winding the embossed tape around the outer peripheral portion of the reel while leaving it empty.

Further, according to the present invention, after the carrier tape is wound on the reel stand on the take-up side, the reel on the take-up side can be automatically exchanged so that the workability can be improved. An object is to provide a winding device.

In this case, it is preferable to extend the cover tape longer than the embossed tape at the winding end portion of the reel, wind the cover tape around the core for a predetermined angle, and then fix the winding end of the cover tape.

As described above, when the carrier tape using the embossed tape is used, as in the conventional example shown in FIG. 7, when the winding start end of the embossed tape Ta is attached to the core Rc of the reel R, it is inserted into the slit Ra. In addition, the work of crushing the tip of the embossed tape Ta is unnecessary, and the work of attaching the winding start end to the core becomes easy.

Further, since only the cover tape is wound several or ten times at the winding end portion of the carrier tape, when the tape is pulled out from the reel by the automatic mounting device, the cover tape is automatically used as the pull-out end. It can be extended into the mounting device. At this time, the pull-out end is only the cover tape, so there is no need to use embossed tape as the pull-out end as in the conventional case.
It is economical because expensive embossed tape is not wasted.

When the end reaches the outer circumference of the reel core, the peeling material is transferred in synchronization with the peeling material transfer means for sending the adhesive tape in the core direction of the reel, and the adhesive is applied to the winding start end of the carrier tape and the outer circumference of the reel core. Press the tape and press the adhesive tape against the winding end of the carrier tape and the outermost carrier tape wound on the reel. It is characterized in that the pressing member is provided.

In this carrier tape winding device, between the winding start end of the carrier tape and the outer peripheral surface of the core of the reel, the adhesive tape directs its adhesive surface toward the outer peripheral surface of the core in synchronization with the transfer of the carrier tape. The adhesive tape is fed out so as to straddle between the winding start end of the carrier tape and the outer peripheral surface of the core, and the adhesive tape is pressed by the pressing member to the winding start end of the carrier tape and the outer peripheral surface of the core to be adhesively fixed. . As a result, the winding start end of the carrier tape and the outer peripheral surface of the core are fixed to each other.

In the above, the carrier tape holding the electronic component is, for example, an embossed tape having recesses formed at a predetermined pitch, in which the electronic components are stored and the opening of the recess is sealed with a cover tape. A first cutting means for cutting only the embossed tape and a second cutting means for cutting the cover tape extending from the end of the embossed tape are provided, and the cover tape is wound at a predetermined angle at the winding end portion. It is preferable that the winding end of the cover tape and the outermost cover tape are fixed with an adhesive tape.

Further, the carrier tape guide member,
The adhesive tape guide member is attached to the guide arm, and the tip of this guide arm abuts against the outer circumference of the reel core by its own weight (biased by its own weight), and the number of tape windings around the outer circumference of the core increases. The guide arm can be configured to be movable to the outer circumference in the radial direction of the reel.

Further, it is preferable that a plurality of reels can be installed on the outer circumference of the rotating body at an equal angle, and the reel for winding the carrier tape can be replaced by rotating the rotating body.

In this carrier tape winding device, when the winding of the carrier tape of the allowable amount is completed for one reel, the rotating body rotates, and then a new reel moves to the winding position. The reel is replaced. The carrier tape guide member and the adhesive tape guide member face the outer circumference of the core of this new reel, and a new winding operation of the carrier tape is started.

The sheet is guided by the guide roller 24, the dancer roller 26, and the guide roller 25 and sent to the winding mechanism section B. In the winding mechanism section B, the reel R on the winding side is mounted on each reel shaft 33 provided on the rotating body 31 at an angle of 90 degrees. The empty reel R from which the carrier tape T is to be wound is moved to the uppermost position (C) by the rotation of the rotating body 31. When starting the winding operation, the expansion rod 46 advances by the cylinder mechanism 47 and intervenes between the flanges Rf and Rf of the reel R at the position (c), and the flanges Rf and Rf are expanded. It Before the winding operation is started, for example, when the rotating body 31 is rotating, the guide arm 50 is rotated counterclockwise by the cylinder mechanism provided in the pedestal 30, and the tip portion is the reel R. Is above. When the flanges Rf and Rf are expanded by the expanding rod 46, the guide arm 50 is rotated clockwise by the cylinder mechanism, and the tip of the arm is located between the flanges Rf and Rf of the reel R. Get in. When the pressing roller 71 at the tip of the guide arm 50 hits the outer peripheral surface of the core Rc of the reel R, the pressure of the drive fluid of the cylinder mechanism is released, and thereafter, the pressing roller 71 is pressed by the own weight of the guide arm 50. Is pressed against the outer peripheral surface of.

The carrier tape T sent to the guide arm 50 is hung on the feed roller 52 shown in FIG.
When the carrier tape T in which the embossed tape Ta and the cover tape Tb are joined is supplied to the feed roller 52, the pinch roller 56 separates from the feed roller 52,
The pinch roller 54 is the shallow groove 52a of the feed roller 52.
Is pressed against. Therefore, the carrier tape T has circumferential grooves 5 on both sides of the embossed tape Ta where the concave portion 1 is not formed.
2a and pinch roller 54, and feed roller 52
It is sent out by the rotating force of.

The carrier tape T fed by the feed roller 52 advances in the tip direction of the arm along the guide portions 57a and 57b of the guide arm 50. When the take-up reel rb is stopped, the feeding of the release material Tc is stopped in a state where the tip of the adhesive tape Td adhered to the release material Tc is aligned with the tip 65a of the release plate 65. When the tip of the embossed tape Ta of the carrier tape T sent is detected by the second detection means 68, the take-up reel rb is wound up, and the peeling material Tc advances on the peeling plate 65. The adhesive tape T is bent from the tip end portion 65a of the plate 65 toward the lower surface of the peeling plate 65.
d is separated from the release material Tc and proceeds (state of FIG. 4).

Since the second detecting means 68 is located slightly behind the front portion 65a of the peeling plate 65, the adhesive tape Td is peeled from the peeling material Tc based on the detection output of the second detecting means 68. Then, the pressure-sensitive adhesive tape Td reaches the position of the pressure roller 71 first, and the pressure-sensitive roller 71 presses the pressure-sensitive adhesive surface of the pressure-sensitive adhesive tape Td against the outer peripheral surface of the core Rc to make the pressure-sensitive adhesive. After that, the carrier tape T is sent out together with the adhesive tape Td, and the adhesive tape Td and the winding start end of the carrier tape T are core R by the pressing roller 71.
It is pressed against the outer peripheral surface of c, and the adhesive surface of the adhesive tape Td is adhesively fixed to the portion of the carrier tape T having a fixed length at the winding start end. Thus, the fixed length portion of the front portion of the adhesive tape Td is fixed to the outer peripheral surface of the core Rc, and the fixed length portion of the rear portion of the adhesive tape Td is the carrier tape T.
When the adhesive tape is fixed to the upper surface of the carrier tape, the outer peripheral surface of the core Rc and the winding start end of the carrier tape T are connected and fixed by this adhesive tape.

The feed length of the release material Tc is the release material Tc.
There is only one pitch of arrangement of the adhesive tape Td adhered to the tape. After the release material Tc is pulled by this one pitch, the rotation of the reel shaft 69 is stopped and the tip of the adhesive tape Tc is removed from the release material Tc. It stops when it coincides with the tip 65a of the plate 65. When the winding start ends of the adhesive tape Td and the carrier tape T are delivered to the outer peripheral surface of the core Rc and adhesively fixed, the drive pad 36 shown in FIG. 2 is pressed against the reel R at the position (c), The power of the motor 32 causes the reel R and the reel shaft 33 to rotate clockwise in FIG. Therefore, after the winding start end of the carrier tape T is fixed to the outer periphery of the core Rc, the carrier tape T is continuously wound by the rotation of the reel R.

As the winding diameter of the carrier tape T around the core Rc of the reel R gradually increases, the guide arm 50 counters its own weight and gradually counteracts the increase in the winding diameter. Rotate clockwise. The carrier tape T is wound up by the allowable amount of the reel R at the position (c),
Alternatively, when the supply of the predetermined type of electronic component W supplied by the supply unit 21 is completed, the winding of the carrier tape T on the reel R at the position (c) is completed.

At the end of winding, the embossed tape T
The supply of the electronic component W to a is stopped, and the carrier tape T is continuously fed out in the taping mechanism portion A in a state where the recess 1 is emptied as necessary. And reel R
After the recess 1 in which the electronic component W to be wound up is stored has passed through the heat seal mechanism section 22, the heat seal mechanism section 22
Then, the seal head 22b is lifted by the cylinder mechanism 22c, and thereafter the cover tape Tb is not welded to the embossed tape Ta, and the embossed tape Ta and the cover tape Tb rotate the feed roller 15 and the feed roller 18 in a state where they are not welded. It is sent out by force.

Embossed tape T not welded to each other
When a and the cover tape Tb are fed by the taping mechanism portion A and the unwelded portion moves to the portion of the first cutting means 23, the rotation of the feed roller 15 and the feed roller 18 is stopped. During this period, the winding mechanism B continues to wind the carrier tape T onto the reel R,
The difference in the feeding speed of the carrier tape T between the taping mechanism portion A and the winding mechanism portion B is absorbed by the rise of the dancer roller 26. In the first cutting means 23, as shown in FIG.
As shown in (A), the cover tape Tb is sucked and lifted by the suction member 23a, and the receiving plate 23e is inserted between the embossed tape Ta and the cover tape Tb. Then, the cutting blade 23c is raised by the cylinder mechanism 23d, and the embossed tape Ta is cut off by the cutting blade 23c.

Immediately after that, in the taping mechanism A, the feed roller 15 and the feed roller 18 are stopped, and the pinch roller 19 is separated from the feed roller 18. Therefore, the feeding of the embossed tape Ta is stopped, and the tip portion of the embossed tape Ta after being cut by the cutting blade 23c does not advance further than the first cutting means 23. However, winding on the reel R is still continued on the winding mechanism B side, and only the cover tape Tb is continuously pulled out from the original fabric r2 in the taping mechanism portion A by the rotational force of the feed roller 52. Then, only the cover tape Tb has a constant length (see FIG.
(L) of (B)), the feed rollers 15 and 18 start rotating again, and at the same time, the pinch roller 19 is pressed against the feed roller 18 and the embossed tape Ta and the cover tape Tb are fed together. At the same time, heat sealing mechanism 2
2, the seal mechanism 22b is driven by the cylinder mechanism 22c.
Is lowered, and heat sealing between the embossed tape Ta and the cover tape Tb is started. Then, in the supply unit 21, the electronic component W is supplied into the recess 1 of the embossed tape Ta wound on the next reel.

Therefore, in the winding mechanism section B, (C)
After the carrier tape T (part (c) of FIG. 5 (B)) preceding the reel R at the position is wound, only the cover tape Tb having the length L is wound, and the next electronic component W is further wound. Carrier tape T that stores (see (to) in FIG. 5 (B))
Part) is sent. At this time, the winding mechanism section B
In the guide arm 50, only the cover tape Tb having the length L is fed, and then the carrier tape T in the (to) portion comes and the tip of the embossed tape Ta is detected by the first detecting means 58. At that point, the feed roller 52 stops for a short time and the tape feed stops. Then, in the second cutting means 59, the pressing member 5 is moved by the cylinder mechanism 59d.
9b is raised, the cover 59a and the pressing member 59b hold the cover tape Tb, and the cutting blade 59c is further raised to cut the cover tape Tb. Immediately after that, the pressing member 59b descends, the feed roller 52 is started, and the cover tape Tb and the carrier tape T after being cut are subsequently fed together in the direction of the front end of the guide arm 50.

Then, when the leading end of the succeeding carrier tape T is detected by the second detecting means 68, the feed roller 52 is stopped, and the operation of the taping mechanism section A is also stopped if necessary. At the same time, the take-up shaft 69 of the take-up mechanism section B rotates, the release material Tc is taken up by the take-up side reel rb, and the release material Tc is fed by one pitch of the adhesive tape Td. Therefore, as in the case shown in FIG. 4, the adhesive tape Td is peeled from the peeling material Tc and supplied to the pressing roller 71, and the end of the cover tape Tb that advances from the position of the detecting means 68 (see FIG. 5B). ) Is adhesively fixed to the cover tape Tb on the inside by the adhesive tape Td.

Therefore, with respect to the reel at the position (C) of the winding mechanism B, the embossed tape Ta is first
And the cover tape Tb are heat-sealed, and the carrier tape T in which the electronic component W is housed is wound up.
Only the cover tape Tb having a length indicated by L in (B) is wound up. Then, the end portion of the cover tape Tb becomes the winding end, and the winding end and the cover tape Tb on the inner peripheral side are fixed by the adhesive surface of the adhesive tape Td, and the winding is completed. When the winding operation is completed, the guide arm 50 is rotated counterclockwise by the cylinder mechanism in the gantry 30, and the tip of the guide arm 50 is located between the flanges Rf and Rf of the reel R in the position (c). Get out of.

Next, the rotator 31 is rotated 90 degrees counterclockwise in FIG. 1 by the power of the motor 32 shown in FIG. 2, the next reel reaches the position (C), and the support mechanism 34 causes the rotator to rotate. The rear surface of 31 is supported, the drive pad 36 is pressed against the side surface of the reel R, and the reel R newly moved to the position of (c) can be rotationally driven. Then, the flanges Rf and Rf of the reel R are expanded by the expanding rod 46, the tip of the guide arm 50 enters in the direction of the core Rc, the taping device A is started, and the feed roller 52 shown in FIG. Is started, the winding start end of the carrier tape T stopped at the position of the second detecting means 68 is sent to the outer periphery of the core Rc, and the adhesive tape Td is also sent out along with this, and the winding start end is fixed to the core Rc. Next, the carrier tape T is wound around the reel R. When the reel R, which has been wound, reaches the position (d) by the rotation of the rotating body 31, the reel R is pushed out by the pushing shaft 43 shown in FIG. 2, and the reel is held by the holding shaft 41 of the discharging mechanism 37. When the handle 42 is turned in the tilting direction, the reel R can be taken out.

In the winding method described above, the winding start end of the carrier tape T in the state where the embossed tape Ta and the cover tape Tb are joined is located on the outer peripheral surface of the core Rc of the reel R, as shown in FIG. Since it is fixed with the adhesive tape Td, the winding start end is reliably fixed to the core Rc, only the cover tape Tb is wound at the winding end portion, and the winding end of this cover tape Tb is fixed with the adhesive tape. Therefore, there is no step at the winding end portion, and winding unraveling is unlikely to occur. Further, as the winding diameter of the carrier tape T on the outer peripheral surface of the core Rc of the reel R increases, the guide arm 50 moves in the outer diameter direction by its own weight, so that the winding can follow the change of the winding diameter. It is possible.

[0059]

As described above, according to the present invention, the winding start end and the winding end are securely fixed by the adhesive tape when the carrier tape is wound around the reel. Further, by winding only the cover tape at the winding end, the step at the winding end can be eliminated and the terminal end can be securely fixed. Also, since the outermost peripheral portion that serves as the pull-out end in the automatic mounting device and protects electronic components is only wrapped with the cover tape, and no embossing tape is used, it is necessary to wastefully use expensive embossing tape. Not economical.

Further, in the winding device of the present invention, since the guide arm operates by its own weight, the structure can be simplified. Further, since a plurality of reels are provided on the rotating body and the reels used for winding can be swiftly replaced by the rotating operation, the work efficiency can be improved.
