Description

Two methods of ceramic substrate

centering are available:

Optical centering

Optical centeringOptical centering

Optical centering

Like the PCB vision module, opti-

cal centering of ceramic substrate

is conducted with the aid of refer-

ence marks (fiducials). Depending

on the contrast ratio the machine

activates the standard lighting or

the oblique lighting contained in

the option:

§ On ceramic and CM blue light.

§ On flexible PCBs using vision

module without IF-filter infrared

light.

Mechanical centering

In certain cases, mechanical cen-

tering is required, e.g., when

placement is to continue to the

substrate edge, when handling of

the edges of the substrate is to be

particularly gentle, or when sub-

strates are scribed. In this gentle,

bounce-free procedure, the sub-

strate is fixed in place in the Y-

direction between a stop rail and

a rocking lever pneumatically

centered in the X-direction.

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.

Length of scanning window: ≤ 90 mm

Label alignment on PCB

transport direction, preferably next to

fixed conveyor side

Scan-in/analysis time

Slack time (T

≤ 1 s), as parallel to the

placement of preceding PCB

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

Each side of the machine is

equipped with a changeover table.

As option, a MTC with a narrow

component table can be placed.

The component feeders are sta-

tionary during the placement proc-

ess, therefore it is possible to refill

components or splice tapes with-

out stopping the machine.

Either individual feeders or the en-

tire changeover table can be ex-

changed during changeover.

Use of component bar codes with

the aid of an optional component

bar code scanner guarantees the

correct assignment of the compo-

nent to the track.

To make full use of the advantages

of the component changeover ta-

ble, the entire set-up including the

check can also be conducted out-

side the machine at the optional

SIPLACE set-up station. The

changeover tables are equipped

with rollers and have an integrated

pneumatic lifting device, eliminat-

ing the need for a lifting device.

Exchanging the tables takes less

than 2 minutes per module.
