Description

Nozzle changers increase

the flexibility of placement

heads when processing dif-

ferent components. The

nozzle configuration can be

quickly modified for new

placement jobs. Exactly

defined positions and the per-

fect seating of the nozzle in

the garage guarantee mini-

mal radial eccentricity at the

placement head.

The nozzle changer for the

20-nozzle Collect&Place

head is equipped with a mon-

itoring circuit which checks

whether the nozzle magazine

is seated correctly on the

mount.

Technical Data

The number of nozzle changers for the Collect&Place heads depends on the number of gantries in the place-

ment area:

- up to four nozzle changers may be installed in the placement area with two gantries.

- up to three nozzle changers may be installed in the placement area with one gantry.

PCB Conveyor

Single Conveyor and Dual Conveyor

Conveyor principle

If the board has reached the

placement area and passed

a light barrier, it is braked. An

additional laser light barrier

determines the position of

the board. As soon as the cir-

cuit board has reached its

target position, the conveyor

belt is stopped and the board

is clamped from below. The

placement process then

starts immediately. Move-

ment and clamping of the

PCBs are monitored.

The conveyor can be easily

matched to many different

PCB widths by the automatic

electrical width adjustment.

The fixed conveyor rail may

be located on the left or right

for both the flexible dual con-

veyor and the single con-

veyor.

Single conveyor

On the single conveyor,

PCBs are moved one after

the other into the placement

machine and placed on a

conveyor track. This con-

veyor variant is particularly

suitable for very wide PCBs.

Flexible dual conveyor

To keep the range of PCBs to

be processed as wide as

possible - whilst maintaining

maximum productivity -

the flexible SIPLACE

dual conveyor

allows you to

choose between single con-

veyor mode and dual con-

veyor mode.

In dual conveyor mode, two

PCBs are moved into the

placement machine and

placed either simultaneously

(synchronous operation)

or alternately (asyn-

chronous opera-

tion).

In synchronous mode,

two PCBs are moved into

the placement position at the

same time. They are pro-

cessed as a common panel.

This allows the top and bot-

tom of PCB to be processed

on the same line and, for

products with very different

components to be placed,

the common optimization of

all the components to be

placed on both PCBs makes

it possible to increase output.

In asynchronous mode,

only one PCB in a transport

track is processed. At the

same time, another PCB in

the second transport track is

moved into the placement

position. This saves

the full conveying

time of one

PCB, thus considerably

increasing performance,

particularly for

PCBs with a

short cycle

time. The

placement

process starts as

soon as one PCB is trans-

ported into the processing

area.

Conveyor buffer

SIPLACE PCB conveyors

have three buffer zones. If

shorter waiting times occur in

a placement area (due to lon-

ger cycle times in the oven,

for example), the down-

stream placement areas can

continue to work since the

unaffected area can easily

access the PCB that is wait-

ing in the buffer zone. This

increases the true output of

the placement line.
