As a result, the head portion 22 positioned at the "seat installation position" is fixed to the backup stage base 12B (fixed relative to the backup stage 12) (third step).

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

After the sheet installation unit 20 is installed on the base 11 according to the above procedure, the component crimping operation by the component crimping device 1 can be performed. When the component pressure-bonding apparatus 1 performs the component pressure-bonding work, first, the board installation section 17 receives two boards KB transported by the board transport section (not shown) from the upstream process side of the component mounting line. , and 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 end portions on which the components BH are mounted via the ACF are positioned on the upper surfaces of the left and right backup stages 12 . At this time, the substrate KB is supported by the backup stage 12 via the sheet SH installed on the upper surface side of the backup stage 12 by the sheet installation unit 20 .

After the two substrates KB are supported by the left and right backup stages 12, the compression cylinder 15 lowers the thermocompression bonding tool 16. As shown in FIG. As a result, the component BH mounted on the edge 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 softens the ACF through the component BH, thereby bonding the component BH to the substrate KB.

When the thermocompression bonding tool 16 presses the component BH against the substrate KB, the thermocompression bonding tool 16 pushes down the protective sheet 18S supplied by the protective sheet installation cassette 18 to abut the component BH from above (the thermal compression shown by the dashed line in FIG. 4). Crimping tool 16). For this reason, the thermocompression bonding tool 16 does not come into direct contact with the board KB and the component BH, and the thermocompression bonding tool 16 is prevented from being contaminated by the ACF protruding from the edge of the component BH.

When the thermocompression bonding tool 16 thermally compresses the component BH to the substrate KB, the substrate KB is pressed against the upper surface of the backup stage 12 by the sheet installation unit 20 via the sheet SH placed on the upper surface of the backup stage 12 . As a result, the substrate KB is heated by the thermocompression bonding tool 16. In the present embodiment, the cooling air Air is blown out from the cooling unit 24 during the thermocompression bonding operation of the component BH by the thermocompression bonding tool 16.

As described above, in the state where the head portion 22 of the seat installation unit 20 is positioned at the "seat installation position", the cooling air Air that the cooling unit 24 blows out from the outlet 24K hits the upper part of the backup stage 12, thereby causing the sheet SH Since (especially, the portion of the sheet SH which is 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. Therefore, 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 may occur due to the excessively high temperature of the substrate KB. can be prevented from occurring.

After the component BH is crimped onto the substrate KB, the crimping cylinder 15 raises the thermocompression bonding tool 16 . When the thermocompression bonding tool 16 is raised, the substrate setting section 17 moves the two substrates KB to the front side of the backup stage 12 and transfers them to the substrate transfer section. After receiving the two boards KB from the board installation section 17, the board transfer section carries out 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 feeder ST, and the backup stage 12 holds the sheet SH fed from the sheet feeder ST. The sheet installation unit 20 installed on the upper surface side of the sheet SH is provided with a cooling section 24 that cools the sheet SH by blowing cooling air Air onto the sheet SH. Therefore, by cooling the sheet SH with the cooling unit 24 during the thermocompression bonding operation of the components BH to the board KB by the thermocompression bonding tool 16, the board KB can be cooled through the sheet SH, and the temperature of the board KB becomes excessively high. situation can be prevented.

In this embodiment, the seat installation unit 20 includes a base portion 21 that is detachably attached to the base 11, and a shaft portion (swing shaft 21c) that is connected to the base portion 21 and extends in the horizontal direction. It has a head portion 22 that can swing freely, and the sheet holding portion 23 and the cooling portion 24 are provided in the head portion 22 . The head unit 22 has a "sheet installation position" where the sheet holding unit 23 is located on the rear side of the backup stage 12 and the sheet SH supplied from the sheet supply unit ST is installed on the upper surface side of the backup stage 12; The sheet holding portion 23 can swing between a "sheet installation preparation position" located on the front side of the backup stage 12. As shown in FIG. Therefore, after the seat installation unit 20 is attached to the base 11 with the head portion 22 positioned at the "seat installation preparation position", the head portion 22 is simply swung to the "seat installation position", and the sheet SH is installed. 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 very easily.
