2.2.11 Twin Head
2.2.11.1 Description
The twin head consists of two identical P&P heads which work according to the pick&place prin-
ciple.The second P&P head is mounted on the gantry at an angle of 180 degrees. Two compo-
nents (one from each P&P head) can be picked up in succession from the feeder module and
optically centered with the help of the camera. On the way to the placement position, the compo-
nents are rotated into the correct position. They are then carefully and precisely positioned onto
the PCB with the help of controlled air kiss and a predefined force.
Type 5xx nozzles are used for the twin head. Type 4xx nozzles from the pick&place head and type
8xx and 9xx nozzles from the collect&place heads can be used with an adapter.
