Example of a Placement Line of SIPLACE Compact machines

Description

Flexibility and adaptability cha-

racterize the modular SIPLACE

design. Each production line can

be individually composed of

similar and different modules.

Because of the small size and ro-

bust construction of the SIPLACE

modules, they can be recombined

quickly and easily to accommodate

changes in production requirements.

SIPLACE line-level optimization

tools generate single set-ups for

single products or for several

products. Also, product programs

can be transferred from line to line

even when the machine configura-

tions are different.

The innovative SIPLACE platform,

with its cutting-edge technology,

guarantees maximum productivity,

while compatibility across several

machine generations ensures you

of long-term investment protection.

And with SIPLACE, you benefit

from a global support network with

29 locations in Europe, 32 locations

in the Americas, and 23 locations in

Asia.

Description

The 6-Nozzle placement head

operates on the Collect & Place

principle. The 6 vacuum nozzles of

the SIPLACE Collect & Place head

rotate around a horizontal axis.

This does not only save space:

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 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

vision system are dumped into

a bin. 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

system 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

This head operates on the Pick

& Place principle. It is suitable for

picking up particularly sophisti-

cated or large components as well

as non-standard models. High-

resolution and intelligent vision

modules ensure that the compo-

nents meet specified tolerances

and that the placement position

is correct.

The sleeve and nozzle are the

heart of the Pick & Place Head.

The sleeve is mounted such that it

is movable in the longitudinal

(Z-axis) and rotational direction

(D-axis). Each of the two axes are

driven by a DC motor and posi-

tioning is done by incremental en-

coder. Due to the high-resolution

glass incremental panel on the

sleeve, the Pick & Place Head has

an outstanding high rotational posi-

tion accuracy. The movement of

rotation is transmitted directly

from the D-axis motor to the driv-

ing plate on the sleeve via frictional

wheel.

Special nozzles and grippers

increase the component range

of SIPLACE CF. They are either

specific for an individual compo-

nent or for a component family

and suitable for the nozzle

changer. The gripper can even

handle easily components without

a surface for vacuum pick-up.
