Description

[Detailed description of the device]

[0001]

[Industrial application]

 The present invention relates to an improved structure of an electronic component centering device used in a device for taping an axial lead type electronic component.

[0002]

[Prior Art]

 A conventional device for taping an axial lead type electronic component will be described with reference to FIG. First, an electronic component that has a U-shaped concave portion formed on the surface and is carried at a constant interval by a conveyor 1 composed of a pair of transport chains facing each other in parallel has an outer periphery at its end. They are picked up one by one by a pair of first intermediate drums 2 having "U" -shaped teeth. That is, it is transferred to the concave portion between the U-shaped teeth of the first intermediate drum 2 that rotates in synchronization with the moving speed of the conveyor 1.

The electronic component transferred to the first intermediate drum 2 is further transferred to the second intermediate drum 3 which also has a U-shaped tooth on the outer circumference. That is, in the figure, the lead terminals of the electronic component are inserted into the space formed between the teeth of the second intermediate drum 3 and the lower outer circumference of the second intermediate drum 3, and the holding plate 4 curved along the outer circumference thereof. While moving. Then, the tip of the holding plate 4 is transferred to the taping drum 5.

As shown in FIG. 6, the taping drum 5 has a plurality of tapes into which a mount tape is inserted, as well as forming "V" -shaped grooves 51, 51 ... Into which lead terminals are inserted. Grooves 52, 52 are formed along the outer circumference. Again, these taping drums 5 and 5 are mounted in a state that a pair of them face each other in parallel. Incidentally, in this figure, the tape groove 52 formed along the outer periphery of each taping drum 5 is shown in only one row for simplification of the drawing.

In such a taping device for an axial lead type electronic component, as shown in the figure, mount tapes T, T are preliminarily formed on the bottom surface of the tape grooves 52, 52 of the taping drums 5, 5 from the bobbin 6 in advance. The lead terminals 11, 11 of the electronic component 10 which are pulled out and wound and arranged and transferred by the second intermediate drum 3 are placed on the mount tape T and at the same time as the taping drum of the taping drum. The V-shaped grooves 51 are arranged at predetermined intervals. At this time, the position of the main body 12 of the electronic component 10 is corrected by the center guide 7 so as to be positioned at the center of the pair of taping drums 5, 5. Thereafter, the adhesive tapes AT 1 and AT 2 having the surface coated with the adhesive are supplied from the bobbin 8, and the adhesive tapes AT 1 and AT 2 are pressed onto the mount tapes T 1 and T 2 by the taping rollers 9 and 9. Be crimped. As a result, the axial electronic component 10 is fixed by sandwiching the lead terminals 11, 11 extended at both ends thereof between the mount tapes T, T and the adhesive tapes AT, AT.

By the way, in the conventional axial lead type electronic component taping apparatus, as shown in FIG. 4, the center guide 7 has the outer peripheral surface of the valley of the “V” -shaped groove 51 of the taping drum 5. A guide groove 71 is formed so as to be curved along the bottom of the portion, and has a U-shaped cross section and the width thereof gradually narrows to have the same width as that of the main body 12 of the electronic component 10. (See especially FIG. 6). Since the guide groove 71 has a wide width on the inlet side and is gradually narrowed from that side, the lead terminals 11, 11 are formed in the valleys of the “V” -shaped grooves 51, 51 of the taping drums 5, 5. When the electronic component 10 inserted and conveyed passes the surface of the center guide 7, the position of the main body 12 is fixed by the guide groove 71, and the position is fixed and held (that is, the mount tape T And the adhesive tape AT) are aligned.

[0007]

[Problems to be solved by the device]

 However, in the above-mentioned conventional technique, there is a problem in the attachment structure of the center guide 7. That is, the center guide 7 in the prior art must be mounted close to these devices because the intermediate drum, the taping drum, etc. are rotating in synchronization with each other and the electronic parts are transferred. Therefore, conventionally, for example, the center guide 7 has been struggling to be placed at an accurate position between the taping drums 5 and 5, and for example, it has been mounted using a steel strip or the like from a distance. .. Therefore, the position of the center guide 7 is moved between the opposing taping drums 5 and 5 due to a slight vibration caused by the power of the device itself, a vibration caused by an external force, etc. The position often shifts, so-called center shift occurs, and defects often occur. Such a center deviation of taping of electronic components is a fatal defect of electronic components supplied by taping.

In view of the above-mentioned problems in the prior art, the present invention is a centering device used in a device for taping an axial lead type electronic component, which does not cause center deviation of the electronic component. It is an object of the present invention to provide a centering device for electronic parts having an improved mounting structure.

[0009]

[Means for Solving the Problems]

 In order to achieve the above object, the present invention forms a plurality of "V" -shaped grooves into which the lead terminal portion of an axial electronic component is inserted, and a flat bottom surface adjacent to the grooves. A pair of taping drums, each having a tape guide groove having a U-shaped cross section, are arranged in parallel so as to face each other, and a “V” -shaped groove on the outer circumference of the taping drum is provided in a space between the pair of taping drums. In a centering device for electronic parts, which has a curved surface along the valley part of the center, and on which is arranged a center guide part consisting of a groove with a U-shaped cross section, the width of which gradually narrows. Further, there is provided a centering device for electronic parts, wherein surface sliding members for filling a space between the pair of taping drums are fixed to both side surfaces of the center guide portion.

[0010]

[Action]

 In the above-described centering device for electronic parts of the present invention, since the surface sliding members for filling the space between the pair of taping drums are fixed to both side surfaces of the center guide portion, the center guide is moved by vibration, for example. Even if you try to do so, both sides are restricted by the sides of the taping drum and cannot move, so the center guide will not be displaced, and the center displacement of the taped and supplied electronic components will be reliably prevented. You can do it. Further, even if the center guides come into contact with the side surfaces of the taping drums on both sides, they smoothly slide on the sliding surface of the surface sliding member, which adversely affects the rotation of the taping drum or causes the center guides to vibrate. Not even.
