Therefore, the head section 22 is fixed to the backup stage base 12B in a stable state.

  When moving (swinging) the head unit 22 from the “sheet installation position” to the “sheet installation preparation position”, the operator OP rotates the knob 41 around the axis of the cylindrical unit 42 to rotate the male screw of the cylindrical unit 42. After unscrewing the female screw in the lock hole 12H, the head portion 22 may be pulled toward the user.

  2, 3, 4, and 5, a sheet feed drive unit 50 is provided on the rear side of the backup stage base 12B. As shown in FIG. 12, the sheet feed drive section 50 has a configuration in which a sheet feed motor 52, a drive gear 53, and an idle gear 54 are provided on a bracket 51 attached to a rear surface of the backup stage base 12B. I have.

  12, the take-up motor 52 has a drive shaft 52J oriented in the X-axis direction, and a drive gear 53 is attached to the drive shaft 52J of the take-up motor 52. The idle gear 54 is rotatably attached to a support shaft 55 extending from the bracket 51 in the X-axis direction (ie, parallel to the drive shaft 52J of the winding motor 52), and meshes with the drive gear 53. Thus, when the sheet feed motor 52 is operated to rotate the drive gear 53 around the X axis, the idle gear 54 rotates in the direction opposite to the drive gear 53.

  The driven gear 33 of the head unit 22 meshes with the idle gear 54 of the sheet feed driving unit 50 when the seat unit 20 is attached to the base 11 and the head unit 22 is located at the “sheet installation position”. are doing. In this state, when the sheet feed motor 52 of the sheet feed drive unit 50 operates to rotate the drive gear 53, the driven gear 33 is driven to rotate via the idle gear 54, and the holding roller 31 rotates. When the holding roller 31 rotates, the sheet SH sandwiched between the holding roller 31 and the pinch roller 32 is sent to the rear side, and the sheet SH is newly pulled out from the sheet supply body ST. The part located above 12 is updated.

  The sheet SH sent to the rear side by the sheet feed drive unit 50 hangs down by its own weight, and is discharged from the shooter 62 (FIG. 2) to the outside of the component crimping device 1 via the sheet guide 61 installed on the back side of the backup stage 12. You. The protection sheet 18S discharged from the protection sheet installation cassette 18 is also discharged from the shooter 62 to the outside of the component crimping device 1 via the sheet guide 61 (FIG. 2).

  In the procedure for attaching the sheet setting unit 20 to the base 11 (method for attaching the sheet setting unit), the operator OP first places the head unit 22 in the "sheet setting preparation position" (FIGS. 8 and 9). ), The base portion 21 is mounted on the base 11 (specifically, a plurality of unit mounting bases 19 provided in a region on the front side of the backup stage 12) (first step; FIG. 13). Then, the sheet SH is pulled out from the sheet supply body ST held by the base portion 21 and the leading end of the drawn sheet SH is sandwiched between the holding roller 31 and the pinch roller 32 (referred to as a sheet installation preparation operation). .

  After performing the above-described sheet installation preparation work, the operator OP swings the head unit 22 from the “sheet installation preparation position” to the “sheet installation position” (FIGS. 8 → 7 → FIG. 4). As a result, the sheet holder 23 moves from the front side of the backup stage 12 to the rear side in an arc-shaped trajectory, and the sheet SH pulled out from the sheet supply body ST and held by the sheet holder 23 is moved to the upper surface side of the backup stage 12. It is installed (second step, FIGS. 4 and 5).

  When the head unit 22 is swung from the “sheet installation preparation position” to the “sheet installation position”, the driven gear 33 on the head unit 22 meshes with the idle gear 54 on the sheet feed drive unit 50 side. As a result, the sheet holding unit 23 is connected to the sheet feeding driving unit 50, and the sheet holding driving unit 50 can drive the sheet holding unit 23.

  When the operator OP has positioned the head unit 22 at the “sheet installation position” as described above, the operator OP operates the lock unit 25 to fit the cylindrical unit 42 into the lock hole 12H (see FIG. 11A). Then, the male screw of the cylindrical portion 42 is screwed into the female screw of the lock hole 12H by rotating around the axis of the cylindrical portion 42 (arrow N shown in FIG. 11B). As a result, the head portion 22 located at the “seat setting position” is fixed to the backup stage base 12B (relatively fixed to the backup stage 12) (third step).

  As described above, in the present embodiment, the sheet installation preparation work can be performed with the head unit 22 positioned at the “sheet installation preparation position” and the sheet holding unit 23 positioned in front of the backup stage 12. Further, after the sheet installation preparation work, the sheet SH can be installed on the upper surface side of the backup stage 12 only by swinging the head unit 22. Therefore, the operator OP can very easily perform the work of setting the sheet SH.

  When the sheet installation unit 20 is installed on the base 11 according to the above procedure, the component crimping operation by the component crimping apparatus 1 can be performed. When performing the component crimping operation, the component crimping apparatus 1 first receives the two boards KB transported by the above-described board transport unit (not shown) from the upstream process side of the component mounting line. And is positioned in front of the left and right backup stages 12. Then, the two substrates KB are moved to the rear side, and the rear ends on which the components BH are mounted are positioned on the upper surfaces of the left and right backup stages 12 via the ACF. At this time, the substrate KB is supported by the backup stage 12 via the sheet SH set on the upper surface side of the backup stage 12 by the sheet setting unit 20.

  When the two substrates KB are supported by the left and right backup stages 12, the pressure bonding cylinder 15 lowers the thermocompression bonding tool 16. Thus, the component BH mounted on the end of the board KB is pressed against the board KB. At this time, the thermocompression bonding tool 16 is heated by a heater (not shown), and the component BH is press-bonded to the substrate KB by softening the ACF through the component BH.

  When the thermocompression bonding tool 16 presses the component BH against the substrate KB, the thermocompression bonding tool 16 presses down the protection sheet 18S supplied by the protection sheet installation cassette 18 and abuts on the component BH from above (the heat indicated by a dashed line in FIG. Crimping tool 16). Therefore, the thermocompression bonding tool 16 does not directly contact the substrate KB and the component BH, and the thermocompression bonding tool 16 is prevented from being stained by the ACF protruding from the edge of the component BH.

  At the time of thermocompression bonding of the component BH to the substrate KB by the thermocompression bonding tool 16, the substrate KB is pressed by the sheet installation unit 20 onto the upper surface of the backup stage 12 via the sheet SH installed on the upper surface side of the backup stage 12. Thus, the board KB is heated by the thermocompression bonding tool 16. In the present embodiment, the cooling air 24 is blown out from the cooling unit 24 at the time of thermocompression bonding of the component BH by the thermocompression bonding tool 16.

  As described above, when the head unit 22 of the sheet setting unit 20 is located at the “sheet setting position”, the cooling air Air blown out from the outlet 24 </ b> K by the cooling unit 24 hits the upper part of the backup stage 12, and thereby the sheet SH. Since (particularly, the portion of the sheet SH placed on the upper surface side of the backup stage 12) is cooled, the substrate KB in contact with the sheet SH is appropriately cooled. For this reason, even if heat is transferred from the thermocompression bonding tool 16 to the substrate KB during the thermocompression bonding operation, the temperature of the substrate KB does not become excessively high, and various adverse effects that can occur due to the temperature of the substrate KB becoming excessively high. Can be prevented from occurring.

  When the component BH is crimped to the substrate KB, the crimp cylinder 15 raises the thermocompression tool 16. When the thermocompression bonding tool 16 is raised, the substrate setting unit 17 moves the two substrates KB to the front side of the backup stage 12 and transfers the substrates KB to the substrate transport unit. Upon receiving the two boards KB from the board setting unit 17, the board transport unit unloads the two boards KB to the downstream process side of the component mounting line.

  As described above, the component crimping apparatus 1 according to the present embodiment is detachably attached to the base 11 to hold the sheet supply body ST, and to transfer the sheet SH supplied from the sheet supply body ST to the backup stage 12. A cooling unit 24 that blows cooling air Air to the sheet SH to cool the sheet SH is provided to the sheet installation unit 20 installed on the upper surface side of the sheet SH. Therefore, by cooling the sheet SH by the cooling unit 24 during the thermocompression bonding of the component BH to the board KB by the thermocompression tool 16, the board KB can be cooled through the sheet SH, and the temperature of the board KB becomes excessively high. Can be prevented.

  Further, in the present embodiment, the seat installation unit 20 includes a base portion 21 detachably attached to the base 11 and a shaft portion (oscillation shaft 21c) connected to the base portion and extending in the lateral direction. The head portion 22 is swingable, and the sheet holding portion 23 and the cooling portion 24 are provided on the head portion 22. The head unit 22 includes a “sheet installation position” where the sheet holding unit 23 is located on the back side of the backup stage 12 and the sheet SH supplied from the sheet supply body ST is installed on the upper surface side of the backup stage 12; The sheet holding unit 23 is swingable between a “sheet installation preparation position” located in front of the backup stage 12. For this reason, after attaching the sheet installation unit 20 to the base 11 with the head unit 22 being located at the “sheet installation preparation position”, the sheet SH is merely swung to the “sheet installation position”. Can be installed on the upper surface side of the backup stage 12, and the installation of the sheet SH and the positioning of the cooling unit 24 with respect to the backup stage 12 can be performed extremely easily.

  Although the embodiment of the present invention has been described, the present invention is not limited to the above-described embodiment, and various modifications and the like are possible. For example, in the above-described embodiment, the cooling unit 24 is configured to blow the air onto the sheet SH to cool the sheet SH. However, another configuration may be used as long as the sheet SH can be cooled. Further, in the above-described embodiment, the head portion 22 of the sheet setting unit 20 is configured to swing around the axis of the shaft portion (swinging shaft 21c) extending in the lateral direction. This is because it is easy to perform the subsequent work of setting the sheet SH on the upper surface side of the backup stage 12, and the head unit 22 does not necessarily have to be swingable. Further, the configuration of the lock portion 25 that fixes the head portion 22 located at the “seat installation position” relatively to the backup stage 12 is not limited to the above-described configuration, and other configurations may be employed.

  Provided are a component crimping apparatus, a sheet installation unit, and a method for mounting a sheet installation unit, which can prevent a situation in which the temperature of a substrate becomes excessively high due to heat transmitted from a thermocompression bonding tool.
