Description

  The present invention relates to an electronic component supply device such as a tape feeder, and prevents a cover tape from being mistakenly peeled off due to the paper fiber of the carrier tape that is attached when the cover tape is peeled off from the carrier tape containing the electronic component in the storage recess. It is related with the electronic component supply apparatus which can do.

  In the electronic component supply apparatus shown in Patent Document 1, a cover tape is inserted into a slit provided in a tape guide as a means for separating a cover tape (top tape) from a carrier tape, and the cover tape is attached to a pair of slit end surfaces constituting the slit. A technique for peeling from a carrier tape is described.

  This slit end surface is formed in an arc shape with an arbitrary curvature with the slit end surface on the carrier tape feeding direction side (downstream side in the feeding direction) centered on the electronic component movement trajectory of the carrier tape. The inner electronic component is pressed down to prevent rotation and rising in the storage recess and to smoothly remove the cover tape.

Japanese Patent Laid-Open No. 11-54989

  However, since adhesive portions for attaching the cover tape are formed on both sides of the edge of the carrier tape, when the cover tape is peeled off from the carrier tape, the upper surface of the carrier tape is formed along both sides of the edge of the cover tape. A part is peeled off, and paper fibers adhere to the lower surface of the cover tape and the upper surface of the carrier tape along the length direction.

  Of the slit end faces of the conventional example, the slit end face on the carrier tape feeding direction side is formed in an arc shape. For this reason, the gap between the left and right ends of the arc portion and the other linear slit end surface facing the arc portion cannot be widened, and the paper fibers adhere to both ends of the arc-shaped slit end surface when the cover tape is peeled off. By repeating this peeling operation, the attached paper fiber grows, and the slit interval is further narrowed, thereby hindering the winding operation of the cover tape. For example, when the winding force of the cover tape is increased, the cover tape is cut, or on the contrary, when the winding force is weaker than the feeding force of the tape, the cover tape is also pulled into the lower surface of the tape guide and cannot be peeled off. In any case, the cover tape may not be smoothly peeled off from the carrier tape and the electronic component may not be adsorbed.

  In order to solve the above-mentioned problem, the invention according to claim 1 includes a carrier tape in which parts are accommodated at equal intervals and an adhesive portion is formed with predetermined intervals on both edges in the longitudinal direction. Taping component supply apparatus comprising: an adhesive cover tape; a driving means for intermittently feeding the carrier tape; a peeling means for separating the cover tape from the carrier tape; and a winding means for winding the cover tape separated from the carrier tape. The peeling means is provided with an edge portion for separating the cover tape from the carrier tape, and a gap between the edge portion and the carrier tape feeding direction, and an interval between the edge portion and the edge of the carrier tape. And a projecting portion having a straight portion having a short length.

  According to the first aspect of the present invention, a length shorter than the interval between the adhesive portions of the carrier tape at the edge facing the edge portion of the protruding portion for preventing the electronic component from protruding from the carrier tape when the cover tape is peeled off. Since the protruding portion having the straight portion is formed, it is possible to prevent the paper fibers attached to the carrier tape and the cover tape from adhering to the protruding portion when the cover tape is peeled off.

  Therefore, the cover tape can be smoothly peeled off from the carrier tape, and the electronic component can be prevented from being mistakenly picked up.

  Examples of embodiments of the present invention will be described in detail below with reference to the drawings.

  As shown in FIG. 1, the component supply device 1 of the present invention includes a reel 2, a carrier tape 3, and a cover tape 4 that are detachably set on a feeder bank body (not shown) and on which a component transport tape A is wound. A tape feeding mechanism 5 that feeds the component transport tape A configured in the transport direction and a recovery reel 6 that peels and recovers the cover tape 4 from the carrier tape 3 are provided.

  As shown in FIG. 2, the carrier tape 3 stores the electronic parts P with the same direction in the storage chamber 3A formed at a constant pitch one by one so that the cover tape 4 does not move or drop out. The carrier tape 3 is bonded by adhesive portions 3B and 3B formed at predetermined intervals L on both sides in the longitudinal direction.

  This component supply device 1 feeds the component transport tape A wound around the reel 2 by the feed mechanism 5 in the transport direction (indicated by the solid arrow in FIG. 1), and collects the cover tape 4 from the carrier tape 3 during the transport. It peels off by winding on the reel 6. The peeled cover tape 4 is peeled off by being wound around the collection reel 6. The peeled cover tape 4 is collected on the collection reel 6 by being sequentially wound around the collection reel 6. The carrier tape 3 is conveyed below the component supply device 1 as shown by a chain line arrow in FIG.

  The peeling means 7 is disposed above the tape feeding mechanism, and as shown in FIG. 3, a linear edge portion 8 for separating and peeling the cover tape 4 at the tip, and in the feeding direction of the edge portion 8 and the carrier tape 3 A projection 9 that protects the carrier tape 3 exposed by the electronic component P is formed with a gap W between the slits S through which the cover tape 4 passes. The protruding portion 9 is formed with a straight portion 9A perpendicular to the tape feeding direction at the tip, and the width H of the straight portion 9A is shorter than the interval L between the adhesive portions 3B and 3B of the carrier tape 3. Yes.

  It should be noted that the edge surface portion of the protruding portion 9 is chamfered, and both corner portions are chamfered (R finish) with a predetermined curvature, so that the load when the electronic component comes into contact is eased and the electronic component is caught. It is preventing.

Next, the operation of the component supply apparatus according to the best mode of the present invention will be described.
As shown in FIG. 2, the carrier tape 3 is fed from the reel 2 to the slit S while being covered with the cover tape 4. As shown in FIG. 4, the cover tape 4 is peeled off by the edge portion 8, and the carrier tape 3 after the cover tape 4 is peeled is pitch-fed to the pickup position.

  On the other hand, the cover tape 4 is folded back to the edge portion 8 and wound around the collection reel 6. At this time, since the protruding portion 9 has a width H shorter than the distance L between the adhesive portions 3B and 3B of the carrier tape 3, the cover tape 4 is peeled off when the cover tape 4 is peeled off from the carrier tape 3. Thus, it is possible to prevent the paper fibers of the carrier tape 3 adhering in large amounts to both edges from adhering to the straight portion 9A of the protruding portion 9.

  FIG. 5 shows a second embodiment of the present invention, and the left and right edge portions 9B of the projecting portion 9 are widened toward the feeding direction of the carrier tape 3 (arrow direction in the figure) as shown in the figure. By using the inclined edge portion 9C as described above, even if the width H of the linear portion 9A of the protruding portion 9 is made shorter, it is possible to prevent the electronic component from rotating and rising when the cover tape is peeled off. It is possible to further reduce the adhesion range to the part.
