Technical Data

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

in the placement 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 Flexible 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.

Position of the conveyor

rails

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.

Conveyor buffer

SIPLACE PCB conveyors

have three buffer zones (see

figure, page 9. If shorter wait-

ing times occur in a place-

ment area (due to longer

cycle times in the oven, for

example), the downstream

placement areas can con-

tinue to work since the unaf-

fected area can easily

access the PCB that is wait-

ing in the buffer zone. This

increases the true output of

the placement line.

Single conveyor

On the single conveyor,

PCBs are moved one after

the other into the placement

machine and placed on a

conveyor lane. 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 con-

veyor allows you to choose

between single conveyor

mode and dual conveyor

mode. In dual conveyor

mode, two PCBs are moved

into the placement machine

and placed either simultane-

ously (synchronous opera-

tion) or alternately (asyn-

chronous operation).

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.

Alternating Placement Mode

SIPLACE X4I I-Placement

In asynchronous mode,

only one PCB in a transport

lane is processed. At the

same time, another PCB in

the second transport lane 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

transported into the process-

ing area.

Alternating placement

mode

In the proven SIPLACE

placement method, the two

heads work alternately on

the PCBs on both conveyor

lanes. While the first head is

placing components on both

PCBs, the other head picks

up new components. With

this new arrangement of the

placement heads and com-

ponent changeover table in

SIPLACE X4I, the output is

much higher in both con-

veyor modes than in a com-

parable SIPLACE X4.

I-Placement

(SIPLACE X4I only)

Another placement concept

has been developed for the

SIPLACE X4I in addition to

synchronous and asynchro-

nous modes. This is known

as I-placement. In this mode,

the two heads work simulta-

neously and populate a PCB

totally independently of one

another. This further in-

creases the output. The

background: the placement

heads and component

feeder modules from the

SIPLACE X-series have

speeded up component pick-

up to such an extent that it is

now the distance compo-

nents are transported to the

PCB that is the speed-limit-

ing factor.
