Description

The 12-Nozzle placement head op-

erates on the Collect & Place prin-

ciple. In contrast to classic chip

shooters, the 12 vacuum nozzles

of the SIPLACE Collect & Place

head rotate around a horizontal

axis. In addition to space savings

this offers the following benefits:

Due to the small diameter com-

pared to chip shooters, the cen-

trifugal forces are significantly

lower. The results are high-speed,

reliable placement and the same

cycle time for all components.

Components are picked up and

placed reliably with the aid of vac-

uum followed by a gentle air kiss.

A number of vacuum tests moni-

tors if 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 records the exact posi-

tion of the feeder table.

§ A camera on the placement head

(component vision module) de-

termines the exact position of

each component on the nozzle.

§ For every feeder the pick-up

offsets are averaged over the

last ten pick-ups. This enables

the head to dial-in on the precise

pick point for each component.

§ 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 compo-

nent is rejected.

§ Components rejected by the vi-

sion system are dumped into a

bin, reject feeder or matrix tray.

Any rejected component gets

automatically placed during a

repair run.

§ Warpage of the PCB is accom-

modated by sensor stop acti-

vated z-axis placement. The sys-

tem also keeps the last ten

positions of the z-axis at com-

ponent placement and uses the

average of these values to im-

prove the drive down and place

speed of the cycle.

Description

A maximum of 2 nozzle changers

can be installed for each of the

12-Nozzle Collect & Place Heads,

which allows for 120 unique noz-

zles per Collect & Place Head

without decreasing feeder quanti-

ties. This allows a quick and reli-

able change of the nozzle configu-

ration when changing to another

job. Damaged or faulty nozzles

can also be exchanged via menu

function.

Description

On SIPLACE HS-50 the in-line

conveyor system guarantees a

quick adjustment to new PCB

widths. The change is made either

at the station computer using the

menu function or from the line

computer via the automatic width

adjustment unit.

As standard the SIPLACE place-

ment systems are available with a

single conveyor system.
