2. Description of the Related Art Small transistors, chip-type electronic parts, etc. are held at equal intervals on a so-called carrier tape and are shipped with the carrier tape wound on a reel. In the user, the reel of such carrier tape is loaded into the electronic component mounter, and while carrying the carrier tape,
Electronic components are automatically loaded while taking out the stored electronic components one by one.

As shown in FIG. 7, the carrier tape T has an embossed tape Ta in which recessed holes a for accommodating electronic parts are formed in an embossed shape at equal intervals in the longitudinal direction, and the electronic parts in each recessed hole. A sealing tape Tb attached to the upper surface of the carrier tape so as to seal the opening of each recess so as not to project outside. The embossed tape Ta is formed of a resin material having a certain shape retention property, while the sealing tape Tb is formed of a flexible thin resin film or the like. When the electronic components are loaded in the recessed holes, the sealing tape is attached to the upper surface of the embossed tape by adhesion.

By the way, the carrier tape T having the recessed holes filled with the electronic components as described above is wound on a reel and shipped while the sealing tape faces outward. The end portion of the carrier tape, which is to form the outermost peripheral portion of the reel, is usually processed as follows.

That is, as shown in FIG. 8, the sealing tape Tb is further extended by a predetermined length from the end portion Ta 'of the embossed tape Ta, and the end portion of the thus extended sealing tape is extended. The end seal b is connected. The bottom surface of the end seal b is an adhesive surface, which prevents the end portion of the sealing tape Tb from adhering to the outermost peripheral portion of the roll-wound carrier tape to prevent the roll from unrolling. To do. As described above, for example, the following device is used to process the end portion of the carrier tape so that the sealing tape further extends beyond the end of the embossed tape.

9 to 11, T indicates a carrier tape which is conveyed in the arrow direction on the conveying path 1 set in the horizontal direction. The carrier tape T has a large number of concave portions as described above. The embossed tape Ta having holes and the sealing tape Tb attached to the upper surface thereof are provided. A first cutter device 2 capable of appropriately cutting the carrier tape T on the transport path 1 is provided at an appropriate portion of the transport path 1. The following configuration is provided in a region of a predetermined length in front of the cutter device 2 in the transport direction.

That is, reference numeral 3 is rotatable above the transport path 1 about a first arm 5 rotatable about a shaft 4 and a shaft 6 at the lower end of the first arm 5 as a center. It shows a sealing tape floating means having a second arm 7 extending rearward in the transport direction and a vacuum suction means 8 provided on the lower surface of the second arm 7.

Reference numeral 9 has an arm 11 which is rotatable about an axis 10 below the conveying path and extends rearward in the conveying direction, and a vacuum suction means 12 is provided on the upper surface of the arm 11. An embossed tape Ta provided and further attached to the upper surface of the arm 11.
It shows an embossing tape cutting means provided with a second cutter device 13 capable of cutting the tape.

Incidentally, in FIG. 11, reference numeral 14 indicates a backup means which moves forward and backward in order to back up the embossed tape Ta from the upper surface when the second cutter device 13 is operated. Further, reference numeral 15 is used to appropriately press the carrier tape T from above and below in the conveying path 1 in front of the sealing tape floating means 3 and the embossing tape cutting means 9 to give the drive in the forward or backward direction. A pair of drive rollers are shown.

The length of the carrier tape T is set substantially corresponding to the diameter of the reel on which the carrier tape is to be wound, and in the vicinity of the end portion, electronic parts are provided in the concave holes a of the embossed tape Ta. It is not loaded, and the embossing tape Ta and the sealing tape Tb are not adhered to each other. The fact that the vicinity of the end portion of the carrier tape T having such a form has reached the transport path can be known by a detection device that optically detects the presence or absence of electronic components in the embossed tape.

When the predetermined length region near the terminal end of the carrier tape T is introduced into the transport path 1 as described above, FIG.
As shown in (1), the first cutter device 2 operates to cut the carrier tape T.

Next, as shown in FIG. 10, the second arm 7 of the sealing tape floating means 3 is rotated upward about the shaft 6 while the vacuum suction means 8 on the lower surface of the second arm 7 sucks and adheres the sealing tape Tb. On the other hand, the arm 11 of the embossing tape cutting means 9 rotates downward about the shaft 10 while suction-attaching the embossing tape Ta by the vacuum suction means 12 on the upper surface thereof. In this way, the second cutter device 13 provided on the arm 11 of the embossing tape cutting means 9 is provided with the embossing tape Ta and the sealing tape Tb in the non-adhesive state separated from each other. Only the embossed tape Ta attached to the upper surface of 11 is cut at a predetermined position in the longitudinal direction of the arm 11. When the second cutter device 13 is activated, as described above,
In order to allow the backup means 14 to advance above the upper surface of the arm 11 to back up the embossed tape Ta from the upper surface and to allow the backup movement of the backup means 14, the sealing tape floating means 3 appears in FIG. As shown in FIG.

When the arm 11 of the embossing tape cutting means 9 is rotated from the horizontal state of FIG. 9 to the downward inclined state of FIG. 10, in order to eliminate the displacement of the embossing tape Ta with respect to the upper surface of the arm 11, Drive roller 1
5 and 15 reversely rotate and move the carrier tape T slightly backward.

Upon completion of each of the above cutting processes, the sealing tape floating means 3 and the embossing tape cutting means 9 return to their original states shown in FIG. 9, and the carrier tape T is conveyed forward.

As described above, the end portion of the carrier tape T is end-treated so that the sealing tape Tb further extends from the end Ta 'of the embossed tape Ta, as already described with reference to FIG. Become. However,
In the terminal processing by the above method, the embossed tape Ta is cut at a fixed position in the longitudinal direction of the arm 11 of the embossed tape cutting means 9, so the embossed tape Ta is cut.
The extension length of the sealing tape Tb that further extends from the end Ta 'of the is inevitably constant, and it is not possible to easily cope with various changes in the extension length of the sealing tape Tb. There is a problem.

Further, since two cutter devices, that is, the first cutter device 2 and the second cutter device 13, are required, the management of the cutter device becomes complicated and the overall operation becomes complicated, so that a quick terminal is provided. There is also a problem that processing cannot be performed.

The present invention has been devised under the above circumstances, and the terminal treatment of the carrier tape is set by setting the extension amount of the sealing tape from the end of the embossed tape to a desired value. Provided are a new carrier tape terminal processing device for electronic parts and a terminal processing method using the same, which can be easily carried out by using a carrier tape and have a simplified mechanism to increase the terminal processing speed of the carrier tape. That is the subject.

[0018]

In order to solve the above problems, the present invention takes the following technical means. That is, in the terminal processing device for an electronic component carrier tape according to claim 1 of the present application, the recesses for storing electronic components are formed at equal intervals, and the recesses are sealed on the upper surface of an embossing tape having a predetermined shape retention property. A terminal portion of a carrier tape for electronic parts, which is attached with a flexible sealing tape for stopping, is processed so that the sealing tape further extends a desired length with respect to the end of the embossing tape. A device for doing

Means and the sealing tape floating means, and if the sealing tape is lifted, only the embossed tape on the conveying path, and if the sealing tape is not lifted, on the conveying path Cutting means for cutting the laminate of the embossing tape and the sealing tape, and pressing which is arranged in front of the cutting means and partially presses the laminate of the embossing tape and the sealing tape during its transportation. Means and are provided.

The invention according to claim 2 of the present application is a method for terminal treatment of a carrier tape for electronic parts using the apparatus according to claim 1, wherein: (a) the embossed tape running on the transport path. The non-adhesive portion near the end of the laminate of the sealing tape and the sealing tape is positioned corresponding to the sealing tape floating means, and the sealing tape floating means causes the sealing tape to extend over a predetermined length. With respect to the above, (b) actuating the cutting means to cut only the embossed tape located below the floating sealing tape, (c) while pushing down the pushing means, Sending the laminate forward a predetermined distance, (d) activating the cutting means to cut the laminate, (e) sending the laminate further forward. It is characterized in that it includes the step of separating from the sealing tape by the pressing means behind the embossed tape from the site that is cut by the step (b).

[0020]

The operation and effect of the present invention: No electronic parts are loaded in the vicinity of the end of the carrier tape, which is a laminate of the embossing tape and the sealing tape, that is, in the recesses of the embossing tape, and this embossing tape is used. On the other hand, when the portion of the predetermined length in which the sealing tape is laminated in the non-adhesive state reaches the transport path in the terminal processing device, the sealing tape floating means sucks the sealing tape by, for example, vacuum suction force. Then, the embossed tape is lifted by lifting it upward. In this state, the cutting means can cut only the embossed tape on the transport path. The cut portion cut by this first cutting defines the end of the embossed tape.
Then, when the operation of the floating means is released, the sealing tape is attached again to the upper surface of the embossed tape on the transport path.

Next, the laminate of the embossing tape and the sealing tape on the conveying path is sent forward by a desired distance. This distance is a distance corresponding to the length of the sealing tape to be further extended with respect to the end of the embossed tape. When the cutting means is operated in this state, the laminated embossed tape and the sealing tape are simultaneously cut. The cut portion of the sealing tape formed by this second cutting defines the end of the sealing tape at the carrier tape end.

Next, the carrier tape is fed further forward, but at this time, since the pushing means pushes down the carrier tape being conveyed in front of the cutting means, it is cut by the first cutting action. The embossed tape following the cut portion is separated downward from the conveying path by the pressing means, and due to the forward movement of the carrier tape, the sealing tape does not return to the conveying path again due to its shape retention property. Is separated from and falls downward. At this time, the sealing seal is pulled to the front portion thereof and, because of its flexibility, is pushed forward by following the end of the embossing tape, despite being pushed by the pushing means.

In this way, the carrier tape is processed into a form in which the sealing tape further extends the desired length with respect to the end of the embossed tape defined by the first cutting action of the cutting means. As described above, the end of the sealing tape is defined by the second cutting action of the cutting means.

As described above, according to the present invention, the carrier tape is conveyed from the first cutting action of cutting only the embossed tape to the second cutting action of cutting the sealing tape together with the unnecessary portion of the embossing tape. By setting the distance as desired, the extension length of the sealing tape from the end of the embossed tape can be easily set as desired.

Since the first cutting action for defining the end of the embossing tape and the second cutting action for defining the end of the sealing tape are configured to be performed by the same cutting means, the apparatus is constituted. However, the operation of each part of the apparatus can be speeded up, and the speed of the carrier tape end processing can be increased.
