Nozzle Changers

Technical Data

Description

Nozzle changers increase the

flexibility of placement heads

when processing different

components. The nozzle con-

figuration can be quickly

modified for new placement

jobs. Exactly defined posi-

tions and the perfect seating

of the nozzle in the garage

guarantee minimal radial

eccentricity at the placement

head.

PCB Conveyor

Single Conveyor

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 con-

veyor is monitored by an in-

tegral control circuit.

The machine 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 of the in-

dividual machines communi-

cate via the optional SMEMA

or Siemens 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.

When the board has reached

the placement area and

passed the light barrier, it is

braked. A laser light barrier

determines the position of

the board. As soon as the cir-

cuit board has reached its tar-

get position, the conveyor

belt is stopped and the board

is clamped from the under-

side. The placement process

then starts immediately.
