Innovation

• The PCB is clamped from

below for placement

→ distance between the

PCB and placement head is

always constant

→ placement rate does

not depend on the PCB

thickness

→ fiducial contours are

always sharply displayed

→ improved PCB fiducial

centering

• The width adjustment unit

has a dedicated control

circuit

→ independent of other

machine components

→ faster and easier to

adjust

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 no longer

dependent on the thickness

of the PCB. The placement

rate is thus 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 sys-

tem quickly adapts to a wide

range of PCB widths. The set-

ting is made using the place-

ment program or via the

station software menu. The

width of the PCB conveyor is

monitored by an integral

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.
