Abstract

A placement head for automatically placing electronic components on a component carrier. The placement head has a chassis; a first rotor assembly that is mounted so that it is rotatable relative to the chassis about a first axis of rotation and that has a first quantity of first handling devices; and a second rotor assembly that is mounted so that it is rotatable relative to the chassis about a second axis of rotation and that has a second quantity of second handling devices. Each handling device includes a sleeve to which a component holding device for temporarily picking up a component can be attached, and a drive device with a linear drive for moving the sleeve along its longitudinal axis, and a rotary drive for rotating the sleeve about its longitudinal axis. Furthermore, a placement machine with such a placement head and a method for automatic assembly of a component carrier using such a placement head.

Dependent claims

A placement head for automatically placing electronic components on a component carrier, the placement head comprising:

a chassis;
a first rotor assembly that is mounted so that it is rotatable relative to the chassis about a first axis of rotation and that has a first quantity of first handling devices;
and
a second rotor assembly that is mounted so that it is rotatable relative to the chassis about a second axis of rotation and that has a second quantity of second handling devices;
wherein each handling device comprises:
a sleeve, on which a component holding device for temporarily picking up a component can be mounted, and
a drive device comprising:
(i) a linear drive for moving the sleeve along its longitudinal axis and
(ii) a rotary drive for rotating the sleeve about its longitudinal axis,
for enabling two or more components to be placed on the component carrier simultaneously or independently,
wherein the first axis of rotation and the second axis of rotation are on a common axis of rotation.
