Description

The 12-Nozzle placement head

operates on the Collect & Place

principle. 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 the

centrifugal 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 po-

sition 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 pre-

cise pick point for each compo-

nent.

 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.

 To check very small compo-

nents, such as 0201, it is helpful

to use a component sensor.

This infra-red sensor checks the

presence of components before

pick-up and placement, ensuring

reliable handling of even the

smallest components.

Nozzle Changer for 12-Nozzle Collect & Place Head (Option)

Technical Data

Type of nozzle All standard nozzles of nozzle series 9xx

Capacity 5 magazines holding 12 nozzles

each per changer

max. 2 nozzle changers per placement head

Nozzle changing time About 2 s per nozzle

a) Nozzles can be of different types.

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-60 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.

The PCB is clamped from the

bottom to the top side of the

conveyor. This offers several

advantages:

 Higher real placement rate

 Robust PCB recognition (cam-

era focus point)

 Shorter PCB change time

 Easier change of fixed conveyor

edge right/left also in field

 Quicker learning function, as the

PCB height does not effect the

Z-stroke, resulting in higher

placement rates

The conveyor can be ordered with

a fixed rail on right or left. As stan-

dard the SIPLACE placement sys-

tems are available with a single

conveyor system.
