Danger

To ensure that your SIPLACE placement machine runs safely, a feeder must be assigned to

every location on the component trolley.

If you do not have enough feeder modules, then you should use dummy feeder modules as

space holders.

The dummy feeder module for the SIPLACE X series occupies one track on the component

trolley.

Description

SIPLACE has a number of

vision modules and a central

vision system to evaluate the

recorded image data, ensur-

ing high placement accuracy.

The PCB vision module is

mounted on the machine's X

gantry. It is used to find the

PCB's positioning-offsets

within the conveyor system.

This vision module is also re-

quired to measure the ma-

chine origin and/or the feeder

module positions on one side

of the table.

Each vision module consists

of a single CCD camera with

integrated lighting and

optics. The offsets in the po-

sition of the PCBs are deter-

mined with the help of at

least two but generally three

reference fiducials on the

PCB. When the PCB arrives

at the placement area the po-

sitioning system with its PCB

vision module moves to the

programmed fiducial. The

edge detection method

allows you to choose pre-

defined fiducials from a

menu (e.g. cross, circle,

square).

The size of the fiducial is pro-

grammed at the station com-

puter. From this time on form

and size of the fiducial is de-

fined and known.

With this data the PCB vision

module is able to search and

recognize the fiducial at the

predefined position on the

PCB or ceramic substrate

without further assistance.

For this reason it places sev-

eral small evaluation win-

dows at the assumed border

of the fiducial. Within these

evaluation windows the vi-

sion system looks for con-

trast transitions between

bright and dark. After finding

such contrasts the actual

position of the fiducial can be

assigned by comparison with

the predefined - and thus

known - shape and size.

The analysis operations can

be used to determine any off-

set with respect to the de-

sired position in the X and Y

directions and the angular

position. Alternatively, a fidu-

cial may be taught as a pat-

tern.

Additional functions of the

PCB vision module include

recognition of the position of

the feeder modules and ce-

ramic substrate (optional)

and recording of the machine

data including mapping.

The bad board detector

(GOOD/SCRAP scan) is also

moved over the ink spot us-

ing the PCB vision module.
