And a sheet take-up unit 12 for taking.

  FIG. 1 is a perspective view of the electronic component crimping apparatus according to this embodiment, and FIG. 2 is a side view of the electronic component crimping apparatus shown in FIG. In order to simplify the drawing, the substrate 60, the electronic component 65, and the ACF tape 63 are not shown in FIG. 1, and a housing 47, a guide rail 43, a motor 41, and a ball screw 42 described later are shown in FIG. The control unit 50 is not shown. In addition, “downstream” in the present application means that it is downstream in the moving direction of the cushion sheet 10.

  1 and 2, the combination of the sheet supply unit 11 and the sheet winding unit 12 is movable in a direction (Y direction) perpendicular to the winding direction of the cushion sheet 10. Specifically, as shown in FIG. 1, each of the sheet supply unit 11 and the sheet winding unit 12 is accommodated in housings 47 and 47, and an orthogonal direction drive mechanism 55 a is provided in the housings 47 and 47. It has been.

  That is, as shown in FIG. 1, a ball screw 42 is connected to each of the housings 47 and 47 via a nut (not shown), and a motor (rotation drive unit) 41 that rotates the ball screw 42 is connected to the ball screw 42. Is provided. A pair of guide rails 43, 43 extending in a direction (Y direction) perpendicular to the winding direction of the cushion sheet 10 is provided on the lower surfaces of the housings 47, 47. Then, an orthogonal direction drive mechanism includes a ball screw 42, a motor 41 that rotates the ball screw 42, and a guide rail 43 that extends on the lower surface of the housing 47 in a direction orthogonal to the winding direction of the cushion sheet 10 (Y direction). 55a is configured.

  As shown in FIG. 1, the motor 41 is connected to the control unit 50. Then, the motor 41 synchronously rotates the ball screw 42 by a predetermined number of rotations according to a signal from the control unit 50, and each of the sheet supply unit 11 and the sheet winding unit 12 is moved along the guide rail 43 by a predetermined distance. , Move in steps.

  Next, the operation of the present embodiment having such a configuration will be described.

  First, the backup tool 2 supports the substrate 60 on which the electronic component 65 is temporarily pressure-bonded via the ACF tape 63 (support step 81) (see FIGS. 2 and 3). That is, in the previous step, the electronic component 65 is preliminarily pressure-bonded on the substrate 60 via the ACF tape 63, and the substrate 60 on which the electronic component 65 is temporarily pressure-bonded in this way is supplied to the backup tool 2.

  Next, the cushion sheet 10 is supplied onto the electronic component 65 temporarily bonded to the substrate 60 by the sheet supply unit 11 (sheet supply step 83) (see FIGS. 1 to 3). At this time, since the wide cushion sheet 10 can be supplied along the longitudinal direction of the backup tool 2 and the pressure unit 1, the cushion sheet 10 is accurately positioned in the width direction, and the cushion sheet 10 is accurately You can send only quantity.

  Next, the cushion sheet 10 supplied from the sheet supply unit 11 is pressed against the electronic component 65 by the pressurizing unit 1 disposed opposite to the backup tool 2, and the electronic component 65 is finally bonded to the substrate 60. (Pressurizing step 85) (see FIG. 2 and FIG. 3).

  Next, each of the sheet supply unit 11 and the sheet winding unit 12 is moved in a direction (Y direction) perpendicular to the winding direction of the cushion sheet 10 (moving step 87) (see FIGS. 1 and 3). Specifically, the motor 41 of the orthogonal direction drive mechanism 55a rotates the ball screw 42 by a predetermined number of rotations according to a signal from the control unit 50, and moves the housings 47, 47 by a predetermined distance in the Y direction. Thus, each of the sheet supply unit 11 and the sheet winding unit 12 moves by a predetermined distance in the positive direction of the Y direction.

  In this manner, the sheet supply unit 11 and the sheet take-up unit 12 are moved in synchronization with the control unit 50 while controlling the number of rotations of the ball screw 42. Can only be moved.

  Thereafter, the pressurizing step 85 and the moving step 87 described above are repeatedly performed a predetermined number of times (see FIG. 3).

  As described above, after the cushion sheet 10 is pressurized by the pressurizing unit 1, each of the sheet supply unit 11 and the sheet winding unit 12 is moved in a direction (Y direction) orthogonal to the winding direction of the cushion sheet 10. Therefore, the wide cushion sheet 10 can be used without waste. For this reason, the replacement frequency of the cushion sheet 10 can be reduced.

  After the pressurizing step 85 and the moving step 87 are repeatedly performed a predetermined number of times, the cushioning sheet 10 pressed against the electronic component 65 by the pressurizing unit 1 is wound up by the sheet winding unit 12 (sheet winding). Taking step 89) (see FIGS. 1 to 3).

  Thereafter, the above-described sheet supply process 83 to the sheet winding process 89 are repeatedly performed until the cushion sheet 10 supplied from the sheet supply unit 11 disappears (see FIG. 3).

  By the way, in the above, as the orthogonal direction drive mechanism, the ball screw 42 connected to each of the housings 47 and 47 in which the sheet supply unit 11 and the sheet winding unit 12 are stored, the motor 41 that rotates the ball screw 42, and the cushion The description has been made using the guide rail 43 that extends in a direction (Y direction) orthogonal to the winding direction of the sheet 10 and that guides each of the sheet supply unit 11 and the sheet winding unit 12. However, the present invention is not limited to this, and the orthogonal direction drive mechanism may move the sheet supply unit 11 and the sheet winding unit 12 in a direction (Y direction) orthogonal to the winding direction of the cushion sheet 10. That's fine.

  In addition, as an orthogonal direction drive mechanism, what moves the sheet | seat supply part 11 and the sheet winding part 12 in steps (Y direction) orthogonal to the winding direction of the cushion sheet 10 by a predetermined distance is preferable. This is because the cushion sheet 10 can be used more reliably and without waste by moving the sheet supply unit 11 and the sheet winding unit 12 step by step by a predetermined distance.

  In the above description, the combination of the sheet supply unit 11 and the sheet winding unit 12 is described using an aspect in which the combination is movable in a direction (Y direction) perpendicular to the winding direction of the cushion sheet 10. However, the combination of the backup tool 2 and the pressure unit 1 may be movable in a direction orthogonal to the winding direction of the cushion sheet 10.

  In addition, since the backup tool 2 and the pressure unit 1 are very heavy, the combination of the sheet supply unit 11 and the sheet winding unit 12 can be moved in a direction (Y direction) perpendicular to the winding direction of the cushion sheet 10. The combination of the backup tool 2 and the pressurizing unit 1 is more preferable than the case where the backup tool 2 and the pressing unit 1 are movable in a direction perpendicular to the winding direction of the cushion sheet 10.

Further, the lower surface of the cassette container 31 is opened so that the cushion sheet 10 pressed by the pressurizing unit 1 is pressed against the electronic component 65.

  Thus, since the cassette container 31 is detachably held by the mounting member 33, when all the cushion sheets 10 held by the sheet supply unit 11 are used, the used sheet supply unit 11 and the sheet are used. By simply removing the cassette container 31 storing the winding unit 12 from the mounting member 33 and attaching the cassette container 31 storing the new sheet supply unit 11 and the sheet winding unit 12 to the mounting member 33, the used sheet supply unit 11 and the sheet winding unit 12 can be replaced with a new sheet supply unit 11 and a sheet winding unit 12.

  As described above, the used sheet supply unit 11 and the sheet take-up unit 12 can be easily replaced with the new sheet supply unit 11 and the sheet take-up unit 12. It is particularly beneficial when the amount of cushion sheet 10 wound around 12 is large and heavy.

  4 to 6, the cassette container 31 is provided with an orthogonal direction moving mechanism 55b that moves the cassette container 31 in a direction orthogonal to the winding direction of the cushion sheet.
