Placement Heads

Nozzle Changers

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 changers for the

MultiStar and the SpeedStar

are equipped with a monitor-

ing circuit which checks

whether the nozzle magazine

is seated correctly on the

mount. The nozzle changer

also detects from the coding

whether it is a magazine for

1xx, 20xx or 28xx nozzles.

SIPLACE MultiStar: 5 magazines for 20xx nozzles

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.
