DESCRIPTION OF EXEMPLARY EMBODIMENTS First Embodiment Hereinafter, a first embodiment of an electronic component crimping apparatus and an electronic component crimping method according to the present invention will be described with reference to the drawings. Here, FIG. 1 thru | or FIG. 3 (a) (b) is a figure which shows the 1st Embodiment of this invention.

  As shown in FIGS. 1 and 2, the electronic component crimping apparatus includes a backup tool 2 that supports a substrate 60 on which an electronic component 65 is temporarily bonded via an ACF tape 63, and an electronic component 65 that is temporarily bonded to the substrate 60. On the upper side, a sheet supply shaft (sheet supply unit) 11 that supplies the cushion sheet 10 and the backup tool 2 are arranged so as to be opposed to each other, and the cushion sheet 10 supplied from the sheet supply shaft 11 is pressed against the electronic component 65. The pressurizing unit 1 for finally press-bonding the electronic component 65 to the substrate 60 and the downstream side of the pressurizing unit 1 (positive direction in the X direction) are pressed against the electronic component 65 by the pressurizing unit 1. A sheet take-up shaft (sheet take-up part) 12 for taking up the cushion sheet 10 is provided.

  FIG. 1 is a perspective view of the electronic component crimping apparatus according to the present embodiment, and FIG. 2 is a side of the electronic component crimping apparatus shown in FIG. 1 viewed from the direction of arrow II (the negative direction of the Y direction) in FIG. FIG. In order to simplify the drawing, the substrate 60, the electronic component 65, and the ACF tape 63 are not shown in FIG. In addition, “downstream” in the present application means that it is downstream in the moving direction of the cushion sheet 10.

  1 and 3A and 3B, the winding direction of the cushion sheet 10 is XY plane (horizontal plane) with respect to the longitudinal direction (X direction) of the backup tool 2 and the pressure unit 1. ). More specifically, as shown in FIG. 3A, the winding direction of the cushion sheet 10 indicated by an arrow in FIG. 3A is in the XY plane with respect to the backup tool 2 and the pressurizing unit 1. It is inclined at an angle of α. In addition, in order to reduce the weight of the cushion sheet 10 and the cassette container 31 described later, to facilitate positioning when the cushion sheet 10 is supplied, and to facilitate replacement of the cushion sheet 10, α is 20 ° to 20 °. It is preferably 45 °, particularly preferably 20 ° to 30 °.

  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 press-bonded via the ACF tape 63 (support process) (see FIG. 2). 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 shaft 11 (sheet supply process) (see FIGS. 1 and 2). At this time, the wide cushion sheet 10 can be supplied onto the electronic component 65 temporarily bonded to the substrate 60. For this reason, as shown in FIG. 5, the cushion sheet 10 is used as the backup tool 2 as in the electronic component crimping apparatus of the type that supplies the narrow cushion sheet 10 along the longitudinal direction of the backup tool 2 and the pressure unit 1. In addition, it is not difficult to accurately position the pressing member 1 in the width direction, and the cushion sheet 10 can be easily supplied to the backup tool 2 and the pressing unit 1 in an appropriate position in the width direction. Can do.

  Next, the cushion sheet 10 supplied from the sheet supply shaft 11 is pressed against the electronic component 65 by the pressing unit 1 disposed facing the backup tool 2, and the electronic component 65 is finally pressed against the substrate 60. (Pressurizing step) (see FIG. 2).

  Next, the cushion sheet 10 pressed against the electronic component 65 by the pressure unit 1 is wound by the sheet winding shaft 12 (sheet winding process) (see FIG. 1).

  After that, the above-described sheet supply process to the sheet winding process are repeatedly performed until the cushion sheet 10 supplied from the sheet supply shaft 11 disappears (see FIG. 1).

  Thus, according to the present embodiment, the winding direction of the cushion sheet 10 is inclined at an angle α in the XY plane with respect to the longitudinal direction (X direction) of the backup tool 2 and the pressure unit 1. (See FIG. 3A). For this reason, the unused cushion sheet 10 can be supplied between the pressurizing unit 1 and the backup tool 2 by moving the cushion sheet 10 slightly in the winding direction. As a result, the narrow cushion sheet 10 as shown in FIG. 5 is supplied from the sheet supply shaft 11 as compared with the electronic component crimping apparatus of the type that supplies the backup tool 2 and the pressure unit 1 along the longitudinal direction. The number of times of use of the cushion sheet 10 can be increased, and the frequency of replacing the used cushion sheet 10 with a new cushion sheet 10 can be reduced.

  Further, as described above, since the winding direction of the cushion sheet 10 is inclined at an angle α in the XY plane with respect to the longitudinal direction of the backup tool 2 and the pressurizing unit 1, as shown in FIG. The width direction of the cushion sheet 10 can be reduced as compared with a type of electronic component crimping apparatus that supplies a wide cushion sheet 10 along a direction orthogonal to the longitudinal direction of the backup tool 2 and the pressure unit 1. For this reason, the weight of the cushion sheet 10 can be reduced, and the load applied to the sheet supply unit and the sheet winding unit can be reduced.

  Moreover, since the weight of the cushion sheet 10 can be reduced in this way, the operator can easily replace the used cushion sheet 10 with a new cushion sheet 10.

  Further, as described above, the winding direction of the cushion sheet 10 is inclined at an angle α in the XY plane with respect to the backup tool 2 and the pressurizing unit 1. In an electronic component crimping apparatus of a type that supplies a wide cushion sheet 10, it is very difficult to obtain a cushion sheet 10 having a sufficient width, and therefore, even for a large substrate 60 that could not be processed. The electronic component 65 can be permanently bonded.

  In the present embodiment, the winding direction of the cushion sheet 10 has been described using the aspect in which the cushion tool 10 is inclined in the XY plane with respect to the longitudinal direction of the backup tool 2 and the pressure unit 1, but is not limited thereto. Without moving the arrangement position of the backup tool 2 and the pressure unit 1, the longitudinal direction of the backup tool 2 and the pressure unit 1 is inclined in the XY plane (horizontal plane) with respect to the winding direction of the cushion sheet 10. You may arrange so that.

  In the above description, the angle α with respect to the longitudinal direction of the backup tool 2 and the pressure unit 1 in the winding direction of the cushion sheet 10 has been described for the counterclockwise direction. The angle α with respect to the longitudinal direction of the backup tool 2 and the pressure unit 1 in the direction may be set in the clockwise direction.

  Furthermore, in the above description, α is preferably 20 ° to 45 °, and particularly preferably 20 ° to 30 °, but is not limited thereto. That is, if attention is paid only to the fact that the electronic component 65 can be finally crimped to the substrate 60 via the cushion sheet 10 by the pressurizing unit 1, α is the inclination width of the cushion sheet 10 (the cushion sheet in the longitudinal direction of the pressurizing unit 1). 10) may be in a range that is longer than the length in the longitudinal direction of the pressure unit 1 (see FIG. 3B). FIG. 3B is an upper plan view showing an arrangement relationship between the pressurizing unit 1 and the cushion sheet 10 according to the present embodiment.

Second Embodiment Next, a second embodiment of the present invention will be described with reference to FIG. In the second embodiment shown in FIG. 4, the cassette container 31 that houses the sheet supply shaft 11 and the sheet take-up shaft 12, and the cushion sheet 10 that is supplied from the sheet supply shaft 11 include the pressure unit 1 and the backup tool 2. And a mounting member 33 that detachably holds the cassette container 31 so as to be disposed between the two. Each of the sheet supply unit and the sheet winding unit is detachably mounted on the cassette container 31. Other configurations are substantially the same as those of the first embodiment shown in FIGS. 1 to 3A and 3B.

  In the second embodiment shown in FIG. 4, the same parts as those in the first embodiment shown in FIGS. 1 to 3A and 3B are denoted by the same reference numerals, and detailed description thereof is omitted.

  In FIG. 4, the cassette container 31 is detachably held by a mounting member 33 at a position where the cushion sheet 10 supplied from the sheet supply shaft 11 is disposed between the pressure unit 1 and the backup tool 2. . For this reason, when all the cushion sheets 10 held on the sheet supply shaft 11 have been used, after the cassette container 31 storing the used cushion sheets 10 is removed from the mounting member 33, a new cushion sheet 10 is stored. By simply attaching the new cassette container 31 to the mounting member 33, the used cushion sheet 10 can be replaced with a new cushion sheet 10.

  As described above, the fact that the used cushion sheet 10 can be easily replaced with a new cushion sheet 10 is that the amount of the cushion sheet 10 wound around the sheet supply shaft 11 and the sheet take-up shaft 12 is large. This is especially beneficial for heavy cases.

  In FIG. 4, the upper surface of the cassette container 31 is opened so that the cushion sheet 10 can be pressed by the pressurizing unit 1. 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.
