In a head module (5) to pick up and place dedicated components in SMT technology, comprising a body (10) of a head module (5), a suction nozzle assembly (40) with a gripping element (41) comprising a vacuum duct (42) inside the gripping element, which at one end is equipped with suction nozzle gripping dedicated components, to which at the opposite end of the suction nozzle a pressure connector is connected supplying vacuum or negative pressure to the vacuum duct which is connected with a through hole of a suction nozzle, a drive (20) of the gripping element generating a rotary motion of the gripping component and a drive (30) for linear movement of the gripping component in relation to the body of the head module mounted on the body of the head module, the drive (20) of the gripping component (41), generating the rotary motion of the gripping component (41), is a stepper motor (21) mounted by its housing (22) to the body (10) of the head module (5), whereby a stepper motor shaft is a hollow shaft (23), inside which the gripping component (41) is seated and coupled displaceably along the hollow shaft (23) axis, using a coupling sleeve (52) of a clearance-free guide (50) with the hollow shaft (23), while the gripping component (41) has the vacuum duct (42) hollow inside, which is connected with a centre through hole (56) of the suction nozzle (55) gripping the dedicated components using the suction end (57), and the drive (30) of linear displacement of the gripping component (41) in relation to the body (10) of the head module (5) is a belt transmission (31) with a belt tensioning pulley (32) and a drive pulley (35) seated on the motor (33) shaft (34) generating motion of a belt (36) of the belt transmission (31), on which a holder (37)) is non-displaceably mounted, whereas the holder (37) allows movement of the rotary seated gripping component (41) rotationally in relation to the holder (37). |
