PCB conveyor SIPLACE SX1/SX2

Single conveyor

Conveyor principle

Once the board has reached

the placement area, it is gen-

tly braked. As soon as the

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 is monitored.

Position of conveyor

edges

The conveyor can be easily

matched to many different

PCB widths by the automatic

electrical width adjustment.

The fixed conveyor edge

may be located on the left or

right for both the flexible dual

conveyor and the single con-

veyor.

Alternating placement

mode

In the proven SIPLACE

placement method, the two

heads process the boards

alternately on both conveyor

lanes. While the first head is

placing components on both

PCBs, the other head picks

up new components.

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 the dual conveyor,

two boards are moved into

the placement machine and

placed either at the same

time (synchronous mode) or

alternatively (asynchronous

mode). This makes it possi-

ble to process the top and

bottom sides of a board in

one line.

Synchronous mode

In synchronous mode, two

PCBs are moved into the

placement position at the

same time. They are pro-

cessed as a common panel.

When using products with

widely differing placement

contents, common optimiza-

tion of the entire placement

content for both boards can

enhance performance.

Asynchronous mode

In asynchronous mode, only

one PCB is processed per

conveyor lane. At the same

time, another PCB in the sec-

ond conveyor lane is moved

into the placement position.

This saves the full conveying

time of one PCB, thus con-

siderably increasing perfor-

mance, particularly for PCBs

with a short cycle time. The

placement process starts as

soon as one PCB is trans-

ported into the processing

area.

I-Placement

In addition to synchronous

and asynchronous conveyor

mode, a new placement con-

cept has been developed for

the SIPLACE SX: I-Place-

ment. In this mode, the two

heads work simultaneously

and populate a PCB totally

independently of one

another. This further

increases the output.

The background: the place-

ment heads and component

feeder modules of the

SIPLACE SX have acceler-

ated component pickup to

such a degree that it is now

the transport path to the

board and not the pickup pro-

cedure which has become

the speed-restricting factor.

Important information for machines in combination with SIPLACE SX2/SX1:

When setting up a machine (S; F, HS, HF, X or D series) next to a SIPLACE SX1/SX2, take note of the limited space

between the two machines. In these cases, you will need a 0.5 m conveyor between the SIPLACE SX1/SX2 and the

adjacent machines.
