And a hanging part 64 that extends downward from the front and rear ends of the side surface of the pressing part 63. A spring 66 is interposed between the claw 65 provided at the lower end of each drooping portion 64 and the spring receiving portion 59b provided on the tape base 59, and the tape pressing member 62 is urged downward by these springs 66. Yes.

  As a result, the carrier tape 10 that engages with the sprocket 43 is biased toward the sprocket 43 by the tape pressing member 62, so that the carrier tape 10 engages with the sprocket 43 even if the thickness of the carrier tape 10 changes. It can be reliably maintained. In FIG. 6, the mounting screws 61 and 69 described above are omitted.

  The tape guide 44 is disposed at a component suction position Pn where the electronic component P is sucked by a suction nozzle (not shown). The tape guide 44 is formed in a U-shaped cross section opened downward, and both side walls 44b are fixed to a mounting member 68 fixed to the main body frame 41 by mounting screws 67 by mounting screws 69. The carrier tape 10 is guided between the walls 44b. On the upper wall 44a of the tape guide 44, a notch 44a1 for taking out the electronic component P accommodated in the carrier tape 10 is formed.

  A tape base 71 is disposed between the tape guide 44 and the mounting member 68 so as to be movable in the vertical direction. A spring 72 as an elastic member is inserted between the tape base 71 and the mounting member 68, and the tape base 71 is biased upward by the spring 72, that is, toward the upper wall 44 a of the tape guide 44. ing. Thereby, the carrier tape 10 is sandwiched from above and below by the tape guide 44 and the tape base 71 and supported by the tape base 71 so as to be transportable.

  Thus, the carrier tape 10 passing through the component suction position Pn is pressed against the tape guide 44 by the tape base 71 biased by the spring 72, and the carrier tape 10 is pressed against the lower surface of the upper wall 44a of the tape guide 44. To be transported. As a result, even if the type (thickness) of the carrier tape 10 changes, the upper surface of the carrier tape 10, that is, the upper surface (suction surface) of the electronic component P accommodated in the carrier tape 10 is positioned on a predetermined reference surface. The adjustment of the suction height of the suction nozzle can be made unnecessary.

  Further, as shown in FIG. 1, a pair of positioning pins 73, 73 are attached to the front end of the main body frame 41, and these positioning pins 73, 73 are inserted into engagement holes of a base (not shown). Thus, the tape feeder 40 is positioned and fixed to the base. A connector 75 connected to the control board 74 is provided between the pair of positioning pins 73, 73. By connecting this connector 75 to the connector on the base side, the control board 74 and the electronic component mounting machine are connected. Are electrically connected so that they can communicate.

  The tape guide 44 is made of a conductive material. As shown in FIGS. 5 and 6, the tape guide 44 is integrally formed with a second peeling member 22 that peels off the top tape 14. At one end of the second peeling member 22, a folded portion 22 a that peels off the top tape 14 and is folded back is formed on the upstream side in the feeding direction of the carrier tape 10 from the component suction position Pn. It is folded and sent by the top tape peeling feed mechanism 47 described above.

  Prior to the top tape 14 being peeled off and folded by the second peeling member 22, the first peeling member 21 made of a conductive material that gradually peels the top tape 14 from one side in the width direction is welded at the center. Is fixed to the tape pressing member 62. The first and second peeling members 21 and 22 made of a conductive material are grounded via the main body frame 41 and a base not shown.

  At the tip of the first peeling member 21, that is, at one end facing the feeding direction of the carrier tape 10, a tongue piece 21a having a pointed tip like a knife is formed, and the tongue piece 21a is the second peeling member. It is provided at a position offset by a predetermined amount on the upstream side of the carrier tape 10 of the folded portion 22a. The other end of the first peeling member 21 passes under the second peeling member 22 with a slight gap and extends to the front of the component suction position Pn, and is welded to the upper wall 44a of the tape guide 44 by welding. Fixed,

  The front end of the tongue piece 21a of the first peeling member 21 is positioned on one end side in the width direction of the top tape 14, and is inclined in the width direction of the top tape 14 along the feed direction of the carrier tape 10 from the front end. ing. When the carrier tape 10 is fed, the tongue piece portion 21a is interposed between the upper surface of the carrier tape body 11 and the top tape 14, and the tongue piece portion 21a is interposed between the carrier tape body 11 and the top tape 14. The seal is peeled off, and the top tape 14 is gradually peeled off from one end side in the width direction.

  At this time, even if one side of the top tape 14 begins to peel off, the component housing hole 12 is blocked by the remaining top tape 14, so that the electronic component P can be prevented from jumping out of the component housing hole 12.

  In addition, since the top tape 14 is gradually peeled from one side in the width direction, generation of static electricity when the top tape 14 is peeled can be suppressed, and vibration applied to the carrier tape 10 can be suppressed. Further, even if the electronic component P is charged by static electricity generated when the top tape 14 is peeled off, the static electricity charged in the electronic component P is brought into contact with the first peeling member 21 made of a conductive material, and the tape feeder 40 It is discharged through the main body frame 41. As a result, the electronic component P accommodated in the component accommodating hole 12 of the carrier tape 10 can be prevented from being stuck to the top tape 14, or attracted to the top tape 14, and can be prevented from standing up or jumping. And conveyed toward the component suction position Pn.

  As described above, since the static electricity generated when the top tape 14 is peeled can be removed, the electronic component P sent to the component suction position Pn is suctioned by the suction nozzle of the mounting head (not shown) in a state where the static electricity is surely removed. As a result, the electronic component P can be picked up accurately and reliably.

  Next, the operation in the first embodiment will be described. The carrier tape 10 sent by the sprocket 43 driven by the motor 48 is sent to the component suction position Pn while being pressed against the lower surface of the upper wall 44a of the tape guide 44 by the tape base 71 biased by the spring 72. It is sucked by a suction nozzle of a mounting head (not shown).

  By the way, prior to the top tape 14 of the carrier tape 10 sent toward the component suction position Pn being folded by the folded portion 22a of the second peeling member 22, the gap between the upper surface of the carrier tape body 11 and the top tape 14 is reached. In addition, the tongue piece portion 21a of the first peeling member 21 is intervened, and the top tape 14 is gradually peeled from the one end side in the width direction by the tongue piece portion 21a. In this case, since the other end side of the top tape 14 is sealed on the upper surface of the carrier tape main body 11, the electronic component P does not jump out of the component accommodation hole 12. Next, the top tape 14 is completely peeled off and folded by the second peeling member 22 and fed by the top tape peeling feed mechanism 47.

  As described above, according to the first embodiment described above, the top tape 14 is gradually peeled from one side in the width direction, whereby generation of static electricity at the time of peeling the top tape 14 can be suppressed, and the carrier Vibration applied to the tape 10 can be suppressed. Further, even if the electronic component P is charged by static electricity generated when the top tape 14 is peeled off, the static electricity charged in the electronic component P is brought into contact with the first peeling member 23 made of a conductive material, and the main body of the tape feeder 10. It is discharged through the frame 41. As a result, the electronic component P accommodated in the component accommodation hole 12 of the carrier tape 10 is held in a stable state and sent to the component adsorption position Pn, and the adsorption operation of the electronic component P is performed accurately and reliably. Will be able to.

  FIGS. 7 to 9 show a second embodiment of the present invention. The difference from the first embodiment described above is that the top tape 14 and the width of the carrier tape 10 are changed by the first peeling member 121. That is, one half of the direction is peeled off and the tape guide 44 is eliminated, and the tape pressing member 62 is extended to the tip of the main body frame 41.

  7 and 8, a tape pressing member 162 made of a conductive material is held at the tip of the feeder main body 41 so as to be movable in the vertical direction. That is, the tape pressing member 162 includes an upper wall 162a and a side wall 162b. The side wall 162b is formed with two elongated holes 162b1 extending in the vertical direction at the front and rear, and the main body frame 41 is inserted through the elongated holes 162b1. A side wall 162b is sandwiched between the head of the mounting screw 80 fixed to the side and the side surface of the main body frame 41 so as to be movable up and down. The tape pressing member 162 is pressed toward the upper surface of the feeder main body 41 by the urging force of the spring 81.

  A first peeling member 121 is integrally formed at the tip of the tape pressing member 162, and a tongue piece 121 a that peels one side in the width direction of the top tape 14 is formed at the tip of the first peeling member 121. . The tongue piece 121 a is interposed between the top surface of the carrier tape body 11 and the top tape 14, and peels half of the top tape 14 in the width direction.

  The second pressing member 122 is fixed to the tape pressing member 162 by welding at a position offset by a predetermined amount in the feeding direction of the carrier tape 10 with respect to the tongue piece 121a of the first peeling member 121. The 2nd peeling member 122 has the folding | turning part 122a which folds the top tape 14, and peels the seal | sticker of the remaining one side of the top tape 14 by folding | folding.

Can be taken out by.

  Further, as shown in FIG. 9, the tape pressing member 162 forms a tunnel portion 83 (see FIG. 9) through which the carrier tape main body 11 from which the top tape 14 has been peeled is passed between the upper surface of the feeder main body 41. The tunnel portion 83 is formed over a predetermined length between the folded portion 122a of the second peeling member 122 and the component suction position Pn. Thus, when the carrier tape 10 is sent by the sprocket, first, the seal on one side between the carrier tape main body 11 and the top tape 14 is peeled off by the tongue piece portion 121a of the first peeling member 121, and then the first 2 The carrier tape body 11 having the top tape 14 peeled off when the seal on the other side of the top tape 14 is peeled off at the folded-back portion 122a of the peeling member 122 is between the tape pressing member 162 and the feeder body 41. And is transported to the component suction position Pn.

  Therefore, even if the electronic component P is charged by static electricity generated when the top tape 14 is peeled off, it is discharged from the first peeling member 121 made of a conductive material through the main body frame 41 of the tape feeder 40. Further, the charged state is surely removed by passing through the tunnel portion 83 formed by the tape pressing member 162.

  Further, on the upper wall 162 a of the tape pressing member 162, a pressing portion 84 that presses the upper surface of the carrier tape main body 11 is integrally formed on the upstream side of the tongue piece portion 121 a of the first peeling member 121. The holding portion 84 is provided offset from the position where the top tape 14 is sealed in the width direction in which the feed hole 13 is formed. When the top tape 14 is peeled off by the first peeling member 121, the carrier tape body 11 is lifted. The upper surface of the carrier tape main body 11 is pressed against the upper surface side of the main body frame 11 so as not to be present.

  According to the second embodiment described above, the top tape 14 is peeled in two stages by the first peeling member 121 and the second peeling member 122, and is given to the carrier tape 10 generated when the top tape 14 is peeled off. Vibration can be effectively suppressed. The static electricity charged on the electronic component P due to the peeling of the top tape 14 is discharged through the first peeling member 121 made of a conductive material. Therefore, as in the first embodiment, the electronic component P sent to the component suction position Pn can be sucked by the suction nozzle of the mounting head (not shown) in a state where static electricity is reliably removed. The electronic component P can be picked up accurately and reliably.

  In the second embodiment, after the top tape 14 is peeled off and folded, the carrier tape main body 11 holding the electronic component P is formed between the tape pressing member 162 and the feeder main body 41. Since it is sent to the component suction position Pn through the tunnel portion 83, even if the electronic component P is not sufficiently discharged by the first peeling member 121, it passes through the tunnel portion 83, Static electricity can be reliably removed.

  Further, in the second embodiment, since the holding portion 84 that holds the upper surface of the carrier tape main body 11 is provided, the carrier tape main body 11 is prevented from being lifted when the top tape 14 is peeled off by the first peeling member 121.
