Description

Despite the highly stable machine

frame, slight distortions of the

gentry axes cannot always be

avoided. With the aid of the map-

ping process the high placement

accuracy of the machine is pre-

served throughout its entire serv-

ice life.

With this calibrating procedure,

which can be conducted quickly

and easily, the PCB camera recog-

nizes the fiducials on a mapping

calibration plate placed in its oper-

ating area. Any distortions are re-

vealed by comparing the nominal

grid on the glass plate with the ac-

tual grid “drawn” by placement

head. These distortions are taken

into account during all further posi-

tioning of X-/Y-axes and thus com-

pensated for.

Description

The control software is coordi-

nated with the modular architec-

ture of the SIPLACE production

line. It is based on a high-level real-

time multitasking operating sys-

tem which is optimally suited for

the control of time-critical proc-

esses in the placement machine.

Window technology and Touch-

Screen operator interface facilitate

handling with the line and station

computers which cooperate

closely in dividing the tasks to be

performed. The context-sensitive

on-line information and help sys-

tem comments on current events

in writing and graphics, for exam-

ple, and offers short information

about button in the toolbar or in

menu entries.

The UNIX multitasking operating

system of the line computer

makes it possible to perform more

than one work sequence at a time.

While the population of a PCB is in

process, for example, it is already

possible to determine the opti-

mized layout of the feeders for the

next PCB type (set-up optimiza-

tion). It is also possible to edit in

several windows or to look into the

MDA/PDA data without affecting

the placement speed. When pro-

duction planning is physically and

organizationally separate from the

production department, it is advis-

able to use a second line computer

as an off-line programming sys-

tem.

Description

The UNIX line computer is as-

signed the following interstation

tasks: creation, revision and man-

agement of placement programs,

job data and component and GF li-

braries; automatic, optimized gen-

eration and administration of ma-

chine set-ups (set-up optimization,

set-up editors); determination of

optimized travel for gantry and

nozzle assignments of the revolver

heads; control and supply of data

to SIPLACE machines in a line;

calculation, storage and display of

machine and operating data; data

backup on built-in magnetic tape

drive.

The Windows station computer in

conjunction with the machine con-

troller with its realtime capability

performs the following jobs: digital

control of the machine gantry sys-

tems; control of PCB input and

output and of PCB transport; moni-

toring functions, handling of mal-

functions and output of error mes-

sages (including Help system);

ensuring the optimal quality of the

placement process; optional load-

ing control by means of compo-

nent bar code and optional place-

ment program change by means

of PCB bar code.
