4.2 Line Computer Modifications

4.2.1 Changing in the GF Editor

To make a scheduling of the 10.7mm high component possible, the maximum height of the com-

ponent has to be changed to 8.5mm in the editor. The last 2.2mm are added to the tolerances.

E.g. a component with 10.7mm height: type 8.5mm in the standard windows for the component

height and the remaining 2.2mm add to the tolerances. 4

All further component related values stay in the same way and are not modified. 4

Program as a nozzle the special nozzle beginning with number 990 or 790! The sensor type stay

as usual number 12 or 13. 4

Please consider the component size related restrictions at the 12 or 6 star head. 4

12 Segment revolver head max. component size:10mm

6 Segment revolver head max. component size:30mm 4

4.2.2 Optimisation dialog

Due to the modified component height in the GF editor, during the optimisation process the ope-

rator has to take care on following issues: 4

You cannot start a usual optimisation as known from the LCU process. 4

When a component with 10.7mm height is placed on a board, there is a “new” shadow effect crea-

ted which will not exist with the standard sleeve an nozzles. After the placement there is a area

around the high component, where the same machine cannot place any components.

This area has a radius from 5.5mm around the high component (Placement shadow = 0.5 x max

component size + 5.5mm) 4

There fore it is recommended to commit this high component with a restriction to the end of line

machine.

All component inside this shadow has to be omitted from the last machine!

After the programming of the restriction it is possible to star the first optimisation. With this first

result it possible to find out if there are still component inside the shadow effect placed or if the

machine is equipped with 711 or 911 nozzles.

If there are still component inside the shadow or if the last machine is using 711 or 911 nozzles

please star again with programming restrictions on these components. 4

Please refer to process flow OPTIMISATION 4

Optimisation process

Comp. higher

than 8.5mm?

STOP Optimisation process

Restrictions

fulfilled?

YES

Step 1:

Bind the high component to last machine of the line

Step 2:

All component which are in the placement shadow have to be omitted

at the specific station.

Step 3:

START first optimisation!

Step 4:

Via the first set-up the user has to verify if there are still components in the

placement shadow placed at the specific machine

Restrictions

fulfilled?

Schedule new job

YES

Step 1 :

The components which are still in the placement shadow

have to be omitted on the specific station

Step 2 :

START optimiser!

Step 3:

Compare again if all rstrictions are fulfilled at the specific machine

YES
