[Detailed description of the invention]

[Industrial Field of Application] The present invention relates to an automatic connection device for a series of chip components, in particular, a carrier tape in which component storage holes are formed continuously and at equal intervals, chip components are stored in the storage holes, and a holding tape is used to connect the chip components. The present invention relates to an automatic connection device for interconnecting a series of chip components configured to hold the chip components in a storage hole.

[Prior Art] Conventionally, chip parts were manufactured using Japanese Industrial Standards (J
It was manufactured as follows based on IS) RC-1009B. That is, component storage holes are continuously provided in the carrier tape at equal intervals, and chip electronic components are sequentially stored in the holes.
Each chip component was held onto a carrier tape using a holding tape. A series of chip electronic components manufactured in this manner is shown in FIG. In FIG. 1, (a) is a plan view of a series of chip parts, (b) and (c) are cross-sectional views of (a), (b) is a paper-type chip series, and (c) is a plan view of a series of chip parts.
) indicates a series of embossed type chip parts. In the paper-type chip component series, after the chip components 3 are stored in the holes 2a of the carrier tape 1a, a top tape 4 and a bottom tape 5 are attached to both sides of the carrier tape 1a to hold the chip components 3. Furthermore, in the embossed type chip component series, after the chip components 3 are stored in the concave component storage hole 2b of the carrier tape 1b, a holding tape 6 is pasted on the top surface of the carrier tape 1b to hold the chip components 3. . Note that 7 is a hole for transporting and positioning a series of chip parts. The series of chip parts produced in this manner is wound into a reel in fixed quantities, and is mounted on a chip mounter using a small device commonly called a tape feeder as a medium. When the last electronic component of the series of chip parts wound on one reel is supplied, it is replaced with the next reel of the new series of chip parts. However, with conventional tape feeders, even if the operator of the chip mounter can predict the shortage of chip electronic components in advance, there is also a need to replace the reel of chip components for safety reasons regardless of whether the tape feeder is fixed or not. This work was impossible without temporarily stopping the chip mounter. In addition, when using a chip mounter whose tape feeder can be easily removed, prepare a certain amount of tape feeders, attach replacement reels to them in advance, and quickly replace the entire tape feeder when replacing due to missing items. Some machines are designed to reduce the downtime of the machine, but when the tape feeder is replaced, due to assembly errors on the machine, the component suction nozzle may be adjusted to pick up the component at the center position. Even so, it can sometimes go awry. especially,
Modern microchip components often lead to pickup errors. In addition, Japanese Patent Application Publication No. 1983-201700

Of course, during this movement, station III is open to allow the taping 10a to pass through. In this case, by the time both tapings 10a and 10b have stopped, they have reached a position where their rear end edges and front end edges are almost in contact with each other. Then, the hole fixing pin 24 is raised by a cylinder or the like from below the passage 13 of Station II, and the pins are fitted into the holes so as to straddle both the tapings 10a and 10b, thereby fixing both the tapings 10a and 10b in a predetermined position. Accurately position and securely fix. In this state, the upper surface fixing fixer 25, which was waiting directly above station II, descends and moves both tapings 10a, 10 in the direction of arrow D.
The adhesive tape of a predetermined length is applied to the upper surfaces of both tapings 10a and 10b by moving it so as to straddle the upper surface of the seam 10a and 10b. The fixer 25 itself is similar to a known adhesive tape supply device, in which adhesive tape is arranged in the form of a belt, and the adhesive tape is cut into a predetermined length as the fixer body moves. It is. Then, both tapings 10a and 10b with adhesive tape attached to the upper surface of the seam are automatically moved to station III. During this moving operation, the lower surface fixing fixer 26, which has a similar structure to the upper surface fixing fixer 25 and was waiting below the passage 13, rises and performs the same operation.
The joint portions of the lower surfaces of both tapings 10a and 10b are pasted with adhesive tape. In addition, both tapings 10a, 10b
At the seam portion, the hole 7 (FIG. 1) is closed with adhesive tape. Both tapings 10a and 10b that have moved to station III are stopped at a predetermined position by a sensor 27. The stopped taping is reliably positioned by a hole fixing pin 28 which is raised from below by a cylinder or the like, except for the area where the adhesive tape is pasted. Next, the hole press unit 29 located directly above is slightly lowered, and as a first step, the taping is held from the upper surface. Next, as a second step, a hole is made again from the upper surface of the adhesive tape using a press pin of the hole press unit 29 in the area where the adhesive tape is pasted. Note that the upper surface of the taping is securely held while the hole press unit 29 is in operation and until the press pin is raised. Upon completion of the above operations, the taping guide (not shown) etc. of the connection passage 13 is automatically opened,
