DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for loading electronic components such as chip resistors or diodes into respective component housings formed in a hoop-shaped carrier tape at appropriate intervals along the longitudinal direction thereof. Related to a taping device.

[0002]

2. Description of the Related Art Generally, in order to tap electronic components such as a chip-type resistor on a hoop-shaped carrier tape, electronic components that are conveyed in a line are transferred by collet means such as a vacuum suction type. A method of picking up and loading into the respective component storage sections of the carrier tape is adopted.

[0003] In this case, the interval between the component storage portions in the carrier tape is smaller than the interval when electronic components are arranged in a line and transported. Therefore, in a conventional taping device, the components are arranged in a line and transported. One of the electronic components to be picked up and loaded into each of the component storage portions of the carrier tape, or a plurality of electronic components are picked up at the same time, and the interval between the electronic components is stored in the carrier tape. After narrowing to fit the interval between the parts, the parts are simultaneously loaded into a plurality of component storage parts of the carrier tape.

[0004]

However, taping of electronic components one by one as in the former case is extremely simple in the structure of the collet means, but on the other hand, taping each of the electronic components one by one. Therefore, the taping speed is remarkably slow, and the cost required for taping is significantly increased. Must be configured to be narrowed to the interval between the respective component storage portions of the carrier tape, and there has been a problem that the structure of the apparatus becomes extremely complicated.

An object of the present invention is to provide a taping device which solves these problems.

[0006]

SUMMARY OF THE INVENTION In order to achieve this technical object, the present invention provides an electronic component transfer path in which electronic components are arranged in a line at regular intervals and are transported in the horizontal direction. A carrier tape transfer path configured to transfer a carrier tape provided with a component storage section at an appropriate interval along the length thereof, and a plurality of electronic components in the electronic component transfer path that are simultaneously picked up and the carrier tape transfer path is selected. And a collet means that moves downward after moving up to a position above the carrier tape, so that the carrier tape is guided in an upwardly convex curved shape to a portion directly below the pickup means in the carrier tape transfer path. A guide means is provided. "

[0007]

In this configuration, the part of the carrier tape directly below the pickup means is curved upwardly and convexly toward the collet means by the guide means, so that each component storage portion in this curved part is formed. Since the interval in the horizontal direction is narrower than the interval in the longitudinal direction along the upper surface of the carrier tape, the interval in the horizontal direction of each of the component storage portions is set to be smaller than the interval of each of the electronic components in the electronic component transfer path. They can be aligned to be approximately the same as the spacing.

Accordingly, a plurality of electronic components in the electronic component transfer path are picked up by the collet means, and then the collet means is moved to a position above the carrier tape transfer path and then moved downward, whereby Each of the plurality of electronic components picked up from the electronic component transfer path can be simultaneously loaded into each of the plurality of component storage portions of the carrier tape.

Therefore, according to the present invention, when the interval between the respective component storage portions of the carrier tape is smaller than the interval between the electronic components along the electronic component transfer path, taping of a plurality of the individual components complicates the structure of the apparatus. This has the effect that it can be achieved without fail.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. In this figure,
Reference numeral 1 denotes a transfer table (electronic component transfer means) for electronic components A such as a chip-type resistor. The electronic components A are arranged in a line at a constant interval P along the upper surface of the transfer table 1 and are horizontally arranged. It is configured to transfer in the direction.

Reference numeral 2 denotes a conventionally known hoop-shaped carrier tape disposed in parallel with the longitudinal direction of the transfer table 1. The carrier tape 2 has a component storage portion 3 along the longitudinal direction. Depressions are formed at regular intervals T. In this case, the interval T between the component storage sections 3 in the carrier tape 2 is smaller than the interval P between the electronic components A in the transfer table 1.

The carrier tape 2 is guided so as to be curved in an upwardly convex shape by winding the carrier tape 2 around a pulley 4 having a radius R which also serves as a guide means and a feed means. By rotation, it is transported in the longitudinal direction under the state of being guided so as to be curved in the upward convex shape. Furthermore, reference numeral 5 is
The collet means 5 reciprocates in a horizontal direction between the upper part of the transfer table 1 and the upper part of the carrier tape 2, and descends at both ends of the reciprocation and then moves up. The reciprocating head 6 is constructed as described above, and the reciprocating head 6 has a plurality of vacuum suction-type collets 7 along the longitudinal direction of the transfer table 1 at intervals P between the electronic components A on the upper surface thereof. The collets 7 are provided in a line at the same interval P, and each of the collets 7 is vacuum-suctioned at the lower limit of the downward movement toward the transfer table 1, and is vacuum-sucked at the lowermost lower limit of the downward movement toward the carrier tape 2. Is configured to be released.

In this configuration, when the collet means 5 is located directly above the transfer table 1, it is moved downward, so that a plurality of collets 7 provided on the upper surface of the transfer table 1 allow the collet means 5 to move downward. Electronic components A
At the same time by vacuum suction. Next, the collet means 5 moves upward, moves laterally to a position immediately above the carrier tape 2 and then moves downward to release the vacuum suction by each collet 7.

In this case, the carrier tape 2
Is guided by the winding around the pulley 4 having a radius R so as to be curved in an upwardly convex shape, so that the space T ′ of each of the component storage portions 3 in the curved portion of the carrier tape 2 along the horizontal direction. Is carrier tape 2
Has a tendency to be narrower than the longitudinal interval T along the upper surface of the component storage portion 3, thereby increasing or decreasing the horizontal interval T ′ of each of the component storage portions 3 when the radius R is curved in the upward convex shape. Can be adjusted so as to be substantially the same as the interval T between the electronic components A in the transfer table 1, so that the collet means 5 picks up when the collet means 5 is lowered and the vacuum suction is released. Each of the plurality of electronic components A can be simultaneously loaded into each of the plurality of component storage sections 3 of the carrier tape 2.

In the above-described embodiment, the carrier tape 2 is wound around the pulley 4 so that the carrier tape 2 is guided so as to be curved in an upwardly convex shape and is simultaneously transported in the longitudinal direction. However, the present invention is not limited to this, and it may be configured such that the guide of the carrier tape 2 so as to be curved upward and the transfer of the carrier tape 2 in the longitudinal direction are performed by different means. It is good.

Incidentally, on the upper surface of the carrier tape 2,
After loading the electronic component A in each of the component storage sections 3,
A cover tape (not shown) for sealing the component storage sections 3 is attached.
