In the future it will be possible to

configure placement heads flexibly

to adapt the production line more

exactly to your requirement profile.

All SIPLACE S-23 HM machines

have been prepared for this modi-

fication.

Description

Flexibility and adaptability are the

outstanding characteristics of the

modular SIPLACE concept. It en-

ables a production line with an in-

dividual combination of identical

and different types of modules.

When the performance require-

ments change, the individual ma-

chines ca be recombined quickly

and easily, because of their rela-

tively small size for example.

The SIPLACE family offers the

right product for each purpose -

from the super high-speed place-

ment system SIPLACE HS-50 to

the high-speed SMD placement

system SIPLACE S-23 HM and the

flexible Fine Pitch placement sys-

tem SIPLACE F

Description

The 12-nozzle revolver head oper-

ates on the Collect & Place princi-

ple. In contrast to classic shooters,

the 12 vacuum nozzles of the

SIPLACE revolver heads rotate

around a horizontal axis. This does

not just save space: Due to the

small diameter compared to

shooters, the centrifugal forces

which develop are significantly

lower. The results are high-speed,

reliable placement and the same

cycle time for all components.

Components are picked up and

placed gently and reliably with the

aid of vacuum or blast air. A num-

ber of vacuum tests indicate

whether the component has been

picked up and placed accurately.

Various control and self-learning

functions further enhance the de-

pendability of the system:

The optical recognition of feeder

positions furnishes the exact

position of the feeder table.

A camera on the revolver head

(component vision module) de-

termines the exact position of

each component on the nozzle.

Offsets in position are corrected

prior to placement and taken

into consideration during further

component pick-up.

In addition, the package form is

also checked. If the actual geo-

metric dimensions of the com-

ponent do not correspond to

those programmed, the place-

ment is not carried out.

Irregularities in the PCB surface

are balanced out due to the

sensor-stop operation while the

nozzle is being lowered and they

are also ”learned”.

Components recognized as be-

ing faulty are rejected by blast

air and are automatically added

during a repair run.

Description

One nozzle changer can be in-

stalled for the 12-nozzle revolver

head on each the left and right of

the PCB conveyor with no loss of

feeder locations. The revolver head

changes the placement quickly and

reliably for the nozzle configuration

required for a particular job. Dam-

aged or faulty nozzles can be ex-

changed via menu function.
