The motor shaft of motor section ZM is connected to the lead screw shaft (not shown) of ball screw framework, and main shaft pressurization part SP is connected to and is set to
The nut of this lead screw shaft.Therefore, if main shaft pressurization part SP is declined by the driving of Z motor section ZM along Z-direction, main shaft pressurization
Portion SP presses the upper end of main shaft part 123, to which main shaft part 123 declines.It is Z motor section ZM applications servo motor, stepper motor, general
The motor of a variety of types such as logical direct current generator, common alternating current generator and form.
The work of the component holding head 100 according to the present embodiment will be illustrated next.
Component placement equipment utilization equipped with the component holding head 100 according to the present embodiment is installed under main shaft part 123
The nozzle section 130 at end is from the pickup (not shown) of component supply department and holding member, by the component transfer of pickup to substrate, and then will
Component is mounted on the precalculated position of substrate, hereinafter, illustrating referring to FIG. 1 and FIG. 2 for the guiding valve portion to 130 application air pressures of suction nozzle
140 work.
The control unit (not shown) of component placement equipment is in the case of the air pressure that needs variation applies suction nozzle 130, driving
Spool actuation motor section 195.
If spool actuation motor section 195 is driven, drive shaft of the cylindrical cam portion 190 from spool actuation motor section 195
195a and rotary shaft S connected to it receives power and rotates at a predetermined angle.The rotation angle in cylindrical cam portion 190 is logical at this time
It crosses the mounting part 193 for being set to cylindrical cam portion 190 and is set to the limitation moving link 111 of a main part 110 and is limited
System.
If cylindrical cam portion 190 rotates, the track 191 in cylindrical cam portion 190 rotates, therefore, be contacted with track 191 and
The roller component 181 being elastically supported is rolled along track 191, and its height change.
If the height change of roller component 181, it is provided with the height of the cam follower setting unit 161 of roller component 181
Variation, therefore the height in drive member portion 160 also changes.When the height change in drive member portion 160 moves, drive member
160 directed section 170 of portion guides and moves.
If drive member portion 160 moves, the slide valve actuation portion 150 for being connected to drive member portion 160 also moves.At this point,
The elastic force continuous action of elastic component 197, to prevent jitter phenomenon, the jump in drive member portion 160 and slide valve actuation portion 150
(jumping) phenomenon, therefore can realize accurate control.
If slide valve actuation portion 150 moves and height change, the service portion 143 and guiding valve 141 in guiding valve portion 140 also move,
Therefore, the air pressure for acting on nozzle section 130 changes.
Slide valve actuation portion 150, drive member portion are utilized as described above, having according to the component holding head 100 of the present embodiment
160, the power generated in spool actuation motor section 195 is transferred to guiding valve portion by cam follower 180, cylindrical cam portion 190
140, to the power pass through mechanism of the movement of spool control valve 141.It is directed to guiding valve portion 140 quickly and precision therefore, it is possible to realize
Control, to suitably control the air pressure for being applied to nozzle section 130, and due to can be by having compared with low torque
(Torque) motor constitutes spool actuation electric motor units 195, thus can reduce spool actuation electric motor units 195 size and
Weight.In turn, since the total quality and the moment of inertia of component holding head 100 can be reduced, be conducive to control unit sticking
First 100 movement.
Also, according to the component holding head 100 of the present embodiment, due to being not provided near guiding valve portion 140 for driving
The motor in guiding valve portion 140, but spool actuation motor section 195 is set in the head main part 110 separated with guiding valve portion 140, therefore,
Space near the guiding valve portion 140 of component holding head 100, which generates, has more than needed, to which designer or operator being capable of effective land productivities
With this excess room.
One side according to the present invention is illustrated as reference with the embodiment of diagram, however these are merely illustrative, in every case
Various deformation and impartial other embodiment can be understood from this by being the personnel for having basic knowledge in this technical field.Cause
This, specified protection domain of the invention needs are determined according to the range of claims.
