Machine Description

Extensions

The options available to ex-

tend the functionality of the

placement machine include

the following:

• Additional component

changeover tables in-

crease machine utilization

since set-up times can be

reduced by carrying out

preliminary set-up off the

machine.

• The flexible dual conveyor

also increases machine

utilization by eliminating

non-productive PCB trans-

port times.

• Automatic nozzle chang-

ers speed up and optimize

the nozzle configuration

process.

• PCB barcode scanners al-

low the production set-up

to be changed over when

triggered by a new

product.

• The productivity lift imple-

ments the concept of par-

allel placement, and thus

improves the ratio be-

tween productive and

non-productive times.

Placement Head

12-Nozzle Collect & Place Head for High-

Speed Placement

Description

The 12-nozzle Collect & Place

head works on the Collect &

Place principle. This means

that, within each cycle,

twelve components are

picked up by the placement

head, are optically centered

on the way to the board and

are rotated into the required

placement angle. Lastly, the

air kiss sets down the compo-

nent gently and accurately

on the board.

Checking and self-learning

functions

The reliability of the Collect &

Place head is increased by

various checking and self-

learning functions.

• For example, vacuum

checks at the nozzles indi-

cate whether the compo-

nent was picked up

correctly.

•A digital component cam-

era on the placement head

determines the precise po-

sition of each component

at the nozzle. Any devia-

tions from the required

pick-up position are cor-

rected before placement

takes place.

• The package form is also

checked and the compo-

nent is not placed if the

geometric data thus deter-

mined differs from the

programmed data.

The vertical axis for picking

up and placing the compo-

nent works in sensor stop

mode, in which differences

in height during pick-up and

any unevenness of the PCB

surface are compensated

during placement.

In addition to the vacuum

check, an optional compo-

nent sensor may be used to

check for the presence of a

component at the nozzle.

The use of a component sen-

sor is recommended, particu-

larly when placing small

components, such as 0201.

High-resolution camera

option

The high-resolution compo-

nent camera allows the

12-nozzle Collect & Place

head to optically center and

place component sizes rang-

ing from 01005

, 0201 to

18.7 x 18.7 mm².
