The SIPLACE PCB bar code scan-

ner supports the flexible manufac-

ture of SMD products and en-

hances placement reliability. It

recognizes all types of cost in gen-

eral use in industry.

The laser scanner reads the bar

code label on the top or bottom of

each PCB while it is being trans-

ported in. On the basis of the bar

code data the line computer auto-

matic selects the correct place-

ment program from the bar code

allocation list previously prepared

and sends it to the station. Once a

bar code filter has been defined,

only the data in the bar code which

has been marked as being relevant

is compared. This procedure is

performed in slack time while a

PCB already in the machine is be-

ing populated. If a number of PCBs

with the same bar code are moved

in one after the other, the program

is only transferred the first time.

The following preconditions apply

for all products which are to be

manufactured with the aid of the

PCB bar code:

identical component set-up on

the individual machines in the

line

all of the PCBs are the same

width.

With a dual conveyor, the sole

purpose of the PCB bar code is to

relay the bar code via a GEM inter-

face. This is imperative for utiliza-

tion. Automatic placement pro-

gram supply is not possible.

Description

SIPLACE S-23 HM is equipped

with two component changeover

tables to the left and right of the

PCB conveyor. The total capacity

is, e.g. 2 x 40 tape tracks, each

8 mm wide.

The component feeders are sta-

tionary during the placement proc-

ess, therefore it is possible to re-

plenish the components (e.g., in

sticks) or to splice on tapes with-

out machine idle.

For the changeover, individual

feeders or all the changeover ta-

bles can be exchanged without any

tools for component tables which

have been set up in advance out-

side the placement machine.

Using component bar codes with

the aid of an optional component

bar code scanner guarantees the

correct allocation of the compo-

nent to the track.

To fully utilize the advantages of

the component changeover tables,

the entire set-up include checks

can also be conducted outside the

machine at the optional SIPLACE

set-up station. The changeover ta-

bles are equipped with rollers and

have an integrated pneumatic lift-

ing device, avoiding the use of a

lifting cart as with the SIPLACE 80

modules. Exchanging the tables

takes less than 2 minutes per

module.

Description

The tape reels of the feeder mod-

ules are accommodated in the

tape container of the component

changeover table. A cutter auto-

matically chops up empty tape

when it comes out.

Feeder modules used on SIPLACE

are distinguished by a short cycle

time and a highly accurate pick-up

position. Product diversity and

small batches sizes are also easily

managed, since changeover of the

modules can be handled quickly:

The increment of the tape cycle is

just as variable as the use of tape

materials. Thanks to the general

purpose tape feeder modules

which are equally suitable for pa-

per and blister tapes, a small range

of module types is sufficient. This

is a decisive advantage for invest-

ment and logistics. Once activated

by a signal from the component

table, the modules control the en-

tire feeder operation of the auto-

matic strip removal all by them-

selves.

The S Feeders series feature

shorter cycle times and they can

handle tapes with 2 mm grids

(8 mm S). 8 mm S and

12/16 mm S are equipped with

component cover.
