*) All 6 magazines must always be set up.

The number of nozzle changers for the Collect & Place heads depends on the number of gantries

in the placement area:

- up to four nozzle changers may be installed in the placement area with two gantries

- up to three nozzle changers may be installed in the placement area with one gantry

Description

For placement, the PCB is

clamped from below. The dis-

tance between the top of the

PCB and the placement head

thus remains unchanged for

each PCB, and is not depen-

dent on the thickness of the

PCB. The placement rate is

also independent of the PCB

thickness.

Since the distance between

the PCB surface and the PCB

camera remains the same,

the PCB camera is always

focussed on the PCB surface

with the same level of sharp-

ness.

The PCB fiducial contours

are optimally mapped on the

CCD chip of the PCB camera.

The inline PCB conveyor

system quickly adapts to a

wide range of PCB widths.

The setting is made using the

placement program or via

the station software menu.

The width of the PCB convey-

or is monitored by an inte-

gral control circuit.

The transport height can be

modified, thus allowing the

machines to be integrated

into lines with a transport

height of 830, 900, 930 or

950 mm.

The PCB conveyors can com-

municate with the individual

machines via the SMEMA

interface.

The fixed transport side can

be located on the left or right

for both the dual conveyor

and the single conveyor.

With this conveyor, the fixed

side can be easily switched

from right to left or vice

versa.

Movement and clamping of

the PCBs are monitored and

controlled by sensors. When

the board has reached the

placement area and passed

the light barrier, it is braked.

A laser light barrier deter-

mines the position of the

board. As soon as the circuit

board has reached its target

position, the conveyor belt is

stopped and the board is

clamped from the underside.

The placement process then

starts immediately.
