Description

Slight distortions of the gantry axis

cannot always be avoided despite

the highly stable machine frame.

With the aid of the mapping ap-

proach, the high placement preci-

sion of the machine is maintained

throughout its service 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. This board has highly

accurate marks on it. Any distor-

tions are located by comparing the

nominal grid on the mapping board

with the actual grid ”drawn” by

the placement head. These distor-

tions are taken into account during

all further positioning of the X-/Y-

axis and they are thus compen-

sated for.

Description

The control software coordinated

with the modular architecture of

the SIPLACE placement line. It is

based on a high-level realtime mul-

titasking operating system which

is optimally suited for controlling

time-critical processes in the

placement machine. Window

technique and Touch-Screen inter-

face simplify the operation of line

and station computers which co-

operate closely in dividing the

tasks to be performed. The con-

text-sensitive on-line information

and help system comments, for

example, on current events in text

and graphics and offers short in-

formation for buttons in the toolbar

or in menu entries.

The UNIX Multitasking operating

system of the line computer

makes it possible to perform sev-

eral work sequences simultane-

ously. While PCB population is in

progress, it is already possible for

example to determine the opti-

mized layout of the feeders for the

next PCB type (set-up optimiza-

tion). It is also possible, without in-

fluencing the placement speed, to

edit in several windows and to

view the PDA/MDA data. When

production planning is physically

and organizationally separate from

the production facilities, it is advis-

able to utilize a second line com-

puter as an off-line programming

system.

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 management of ma-

chine equipment (set-up

optimization, set-up editors); de-

termination of optimized travel

paths for gantries and nozzle allo-

cations for the revolver heads:

control and supply of data to the

SIPLACE machines in a line; scan-

ning, storage and display of ma-

chine and production data; data

back-up on built-in magnetic tape

drive.

The Windows station computer

performs the following tasks in

conjunction with the machine con-

troller which has realtime capabil-

ity: Digital control of the machine

gantry systems; control of PCB

loading and unloading as well as

PCB conveyor; monitoring func-

tions, handling of disruptions and

output of error messages (includ-

ing help system); ensuring optimal

quality of the placement process;

optional set-up check by means of

component bar code and optional

placement program change by

means of PCB bar code.
