<Nozzle member>
Hereinafter, the rotation and movement of the nozzle member 3 by the rotation motor 72, the rotation motor 51, and the elevating motor 61 will be described.

As shown in FIG. 5, by driving the rotation motor 72, the first rotation driven gear 74 of the second rotation shaft 71 mechanically connected to the rotation drive gear 73 rotates. As the first rotation driven gear 74 rotates, the second rotation shaft 71 rotates with the vertical direction as the rotation axis. As the second rotation shaft 71 rotates, the second rotation driven gear 75 rotates. Then, as the second rotation driven gear 75 rotates, the third rotation driven gear 31d fixed to each of the nozzle members 3 rotates. In this way, each of the plurality of nozzle members 3 rotates (rotates) around the rotation axis of the nozzle shaft 31.

When the rotation motor 51 is driven, the first rotation shaft 53 rotates with the vertical direction as the rotation axis. As the first rotation shaft 53 rotates, the nozzle pressing member 4 rotates. Here, as the nozzle pressing member 4 rotates, the base 41 and the pressing body 42 integrally rotate on the rotation axis of the first rotation shaft 53. As a result, the nozzle pressing member 4 can be moved to a desired position above the nozzle member 3.

The ball screw 62 is rotated by driving the elevating motor 61. As the ball screw 62 rotates (forward rotation), the moving body 63 moves downward. As the moving body 63 moves downward, the moving body 63 and the connecting body 64 move downward integrally. Then, as the connecting body 64 moves downward, the connecting body 64 and the nozzle pressing member 4 move downward integrally. As a result, the pressing body 42 of the nozzle pressing member 4 can move downward. At this time, the first elastic material 53d moves downward to the first elastic material 53d when the base 41 of the nozzle pressing member 4 moves downward due to the moving body 63 moving downward and the connecting body 64 moving downward. The force of is applied and it shrinks. At this time, the nozzle 32 moves to a position where the component is attracted or mounted.

The ball screw 62 is rotated by driving the elevating motor 61. As the ball screw 62 rotates (reverse rotation), the moving body 63 moves upward. When the moving body 63 moves upward, the moving body 63 and the connecting body 64 move upward integrally. Then, as the connecting body 64 moves upward, the connecting body 64 and the nozzle pressing member 4 move upward integrally. As a result, the pressing body 42 of the nozzle pressing member 4 can move upward. At this time, in the first elastic material 53d, the moving body 63 moves upward and the connecting body 64 moves upward, so that the base 41 of the nozzle pressing member 4 moves upward. As a result, the first elastic material 53d extends upward due to the urging force of the first elastic material 53d. At this time, the nozzle 32 moves to the standby position.

In this way, by driving the rotation motor 72, the rotation motor 51, and the elevating motor 61, the desired nozzle member 3 is rotated and moved up and down.

In the nozzle 32 of the nozzle member 3, a negative pressure is applied to the first air passage 71a. At this time, when the solenoid valve 223 is operated to communicate the first air passage 71a and the third air passage 32a, a negative pressure is applied to the third air passage 32a via the first communication passage 22c. As a result, a negative pressure is applied to the tip of the nozzle 32, and the component can be attracted to the nozzle 32. Further, in the nozzle 32 of the nozzle member 3, positive pressure is applied to the second air passage 53e. At this time, when the solenoid valve 223 is operated to communicate the second air passage 53e and the third air passage 32a, a positive pressure is applied to the third air passage 32a via the second passage 22d. As a result, a positive pressure is applied to the tip of the nozzle 32, and the components attracted to the nozzle 32 can be mounted on the substrate 16.

As a result, the nozzle pressing member 4 moves up and down by the driving force of the elevating motor 61, so that the elevating position of the nozzle pressing member 4 can be adjusted by adjusting the driving of the elevating motor 61. As a result, the elevating position of the nozzle pressing member 4 can be adjusted according to the vertical position of the substrate 16 on which the component is mounted.

Further, in the present embodiment, the nozzle pressing member 4 can be integrally rotated together with the first rotating shaft 53. Further, the nozzle pressing member 4 can be raised and lowered independently of the first rotating shaft 53. As a result, the nozzle pressing member 4 can rotate around the central axis of the first rotating shaft 53 and can move along the central axis of the first rotating shaft 53. As a result, since the first rotating shaft 53 is used as a common configuration in the circumferential movement mechanism 5 and the elevating movement mechanism 6, the configurations of the circumferential movement mechanism 5 and the elevating movement mechanism 6 can be simplified. Can be done.

Further, in the first embodiment, the component mounting head 2 includes a nozzle rotation mechanism 7 that rotates each of the plurality of nozzles 32 around the central axis. As a result, the second rotation shaft 71 can rotate the plurality of nozzles 32 around their respective central axes. As a result, the position and angle of the parts attracted to the nozzle 32 with respect to the horizontal plane can be adjusted.

Further, in the first embodiment, the second rotating shaft 71 has a double structure arranged inside the first rotating shaft 53. As a result, the space for arranging the first rotation shaft 53 and the second rotation shaft 71 can be reduced as compared with the case where the first rotation shaft 53 and the second rotation shaft 71 are separated. As a result, the component mounting head 2 can be miniaturized, so that the weight of the component mounting head 2 can be reduced.
