Description

The component bar code scanner

enables a speedy, reliable set-up

and component replenishment

verification. To this end the bar

codes of the tracks (on the track

scale on the feeder table) and the

components allocated to them (bar

code labels on tapes, Bulk Cases,

etc.) are read in with a hand scan-

ner. An audible and optical signal

acknowledges a successful read-

ing operation. If a label is dam-

aged, the bar code can also be en-

tered at the keyboard.

The allocation of the components

to their respective track is de-

scribed in the set-up data. If the

data received from the bar code

scanner does not correspond with

the set-up data, an error message

is displayed.

Component table change Time expanded: 2 min / table side

Description

The component changeover tables

can be set up and checked at an

external SIPLACE set-up station

quickly and without machine idle

time. The costs for production in-

volving a wide variety of compo-

nents are greatly reduced. During

the bar code check outside the

machine, 10 minutes of machine

standstill are eliminated per set-up

change. All current data from up to

4 lines are accessible over a link to

the line computer via a Local Area

Network (LAN).

Description

The SIPLACE HS-60 has a number

of vision modules and a central vi-

sion system to evaluate the re-

corded image data ensuring high

placement accuracy.

At the machine´s X-gantry the PCB

vision module is mounted. It is

used to find the PCBs´ positioning-

offsets within the conveyor sys-

tem.

This vision module is also required

to measure the machine origin

and/or the feeder positions on one

side of the table. It consists of a

single CCD camera with integrated

lighting and optics.

The offsets in the position of the

PCBs are determined with the

help of at least two but generally

three reference fiducial marks on

the PCB. When the PCB arrives at

the placement area the positioning

system with its PCB vision module

moves to the programmed mark

position.

Using the Geometrical Alignment

allows to choose predefined

marks from a menu (e.g. cross,

circle, square). The size of the

mark is programmed at the Station

Computer. From this time on form

and size of the mark is defined and

known.

With this data the PCB vision

module is able to search and rec-

ognize the mark at the predefined

position on the PCB or ceramic

substrate without further assis-

tance. For this reason it places

several small evaluation windows

at the assumed border of the

mark. Within these evaluation win-

dows the vision system looks for

contrast transitions between

bright and dark. After finding such

contrasts the actual position of the

mark can be assigned by compari-

sion with the predefined – and

thus known – form and size.

Ink spot, e.g. square

Evaluation operations calculate

possible PCB offsets against given

values of X-, Y- and Theta-axis.

Saving the mark by teaching is not

necessary any more.

Additional functions of the PCB

vision module are recognition of

the position of the feeders and

ceramic substrate (optional) and

recording of the machine data in-

cluding mapping.

In addition, the bad board recogni-

tion unit handles “ink spots” with

the aid of the PCB vision module.
