Description

Like the PCB vision module, optical

centering of ceramic substrate is

conducted with the aid of refer-

ence marks (fiducials). Depending

on the contrast ratio the machine

activates a standard lighting or the

oblique lighting.

§ On ceramic and CM blue light.

§ On flexible PCBs using vision

module without IF-filter infrared

light.

Description

The SIPLACE PCB bar code scan-

ner supports the flexible produc-

tion of SMD products and en-

hances placement reliability. It

recognizes all code types in gen-

eral use for industrial applications.

The laser scanner reads the bar

code label on the top and/or bot-

tom of each PCB moving during

transport. On the basis of the bar

code information the line computer

automatically selects the correct

placement program from the pre-

viously prepared bar code assign-

ment list and sends it to the sta-

tion. This procedure is performed

in slack time while a PCB already in

the machine is being 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 fol-

lowing preconditions apply for all

products which are to be manufac-

tured with the aid of the PCB bar

code:

§ identical component set-up at

the individual machines in the

line

§ all PCBs of same width.

The bar code filter can be utilized,

if only certain information con-

tained in the bar code is relevant.

a) This value can only be met if the bar code label on the PCB moves through the bar code scanner at

right angles to the machine’s direction of transport.

b) Depending on where the bar code label is located on the PCB, the position of the bar code scanner

can be easily adjusted in the input conveyor belt.

Description

SIPLACE HS-50 is equipped with

four stationary component tables,

one for each placement head. With

these four tables SIPLACE HS-50

can accommodate a total of 144

different 8 mm part numbers.

On the changeover tables tape

feeders and Bulk Case feeders

can be positioned. For safety rea-

sons tracks not in use should be

equipped with guards for feeder

locations.

Component feeders are stationary

during the placement process. This

allows for the replenishment of

both tape and bulk components

during machine operation.

For the changeover, individual

feeders or entire changeover ta-

bles can be exchanged without the

use of tools or external lifts. Job

changeover times can be dramati-

cally reduced with the use of addi-

tional feeder tables. This will allow

large set-ups to be completed off

line without impacting machine

production time

Using component bar codes with

the optional Component Bar Code

Scanner guarantees the correct

allocation of component to track.

Changeover tables are equipped

with rollers and an integrated

pneumatic lifting device which

eliminates the need of an external

lifting cart as with other equip-

ment. Exchanging the tables takes

less than 2 minutes per module.
