Description

Nozzle changers increase

the flexibility of placement

heads when processing dif-

ferent components. The noz-

zle 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.

Up to eight nozzle changers

may be installed on the

SIPLACE D4i machine as an

option.

PCB Conveyor

Overview

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

circuit 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.

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 simultaneously

(synchronous operation) or

alternately (asynchronous

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.

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

transported into the process-

ing area.

Conveyor buffer

SIPLACE PCB conveyors

have 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.
