6.4 Station SW Menu Functions Combined with 'Fiducials'

The station software offers a fiducial position correction function for incorrectly positioned PCBs. This

allows you to correct the position of the PCB position recognition fiducials and to then continue

placement.

6.4.1 Machine Functions

Gantries 2 and 4 or the left-hand gantry in the machine determine the PC position in the machine for the

placement process.

Error messages relating to the fiducial position are only issued for these gantries.

To rule out temperature influence for high-precision applications, gantries 1 and 3 or the right-hand

gantry in the machine measure the PCB position deviation, compared to the partner gantry for the 1st

PCB or the position fiducials for the next PCB, after a minimum of 300 seconds.

6.4.2 Fiducial Position Teaching

The position needs to be trained in 3 separate steps for each PCB position fiducial. After the error

message

Fiducial not found,

you can switch over to the fiducial teach menu for the teaching process.

The fiducial positions are only learnt for the placement process in the respective placement area of the

machine. When the PCB is transported out of the placement conveyor, the position offset of the fiducial

is set back to 0.

If this position offset was caused by a programming error, you will need to perform correction in SIPLACE

Pro.

In this menu you can also open other SIPLACE Vision fiducial teaching functions and then save their

respective results after editing.

6-18: Teaching the fiducial position

The PCB fiducial position is shown in the

SIPLACE Vision fiducial teach menu as a position

teach menu (1).

The X axis (2) of the camera position shows

0.7 mm (3), this being the original gantry position

before correction (7 marker lines on the coordinate

cross) and therefore points to the fiducial center

through movement of the gantry.

NOTE:

Due to the camera installation, X

cam1

corresponds to the - Y

coordinate.

6.5 Feeder Position Recognition Fiducials

There is a special type of fiducial available for feeder position recognition.

In this section we will not cover the feeder position recognition function in the machine but merely touch

on the basic functions which SIPLACE Vision makes available for this.

The optical recognition is performed by enabling the Vision interface in the "setup staff" operator level,

during the startup sequence.

This fiducial, specified as a component pocket in SIPLACE Pro, can be programmed to a maximum size

of 2x2 mm.

6.5.1 Component Pocket Fiducials

X feeders

S feeders

Only those fiducials which support the pickup

position with component in the 8 mm tape pocket

are made available for X feeders. The fiducial is

automatically generated from the CS body data, if

the component length is 1.0 mm (0402) or less. If

the component is larger, feeder position

recognition can not be forced even by teaching a

pickup position fiducial.

There are 2 methods of feeder position recognition

for S feeders (for 8 mm feeders only):

 Pickup position fiducials (tape pockets)

When components with a length of 0.6 mm or

shorter are in the 0201(01005) 3x8 mm S

feeder.

Teaching pickup position fiducials (in extreme exceptions only)

Teaching - prerequisites and menus:

X Creates a fiducial in SIPLACE Pro and defines this as a component pocket.

X Assign the fiducial to the feeder track of the required component (observe component sizes as

explained).

X The

Line Engineer level

is active.

X The machine (placement run) has been stopped.

X Open the

Set up

menu (the feeder position recognition fiducials are NOT part of the placement

information!).

X The menu buttons:

Component pocket list

and

Test component

are only active when the machine

has been stopped.

X Select the incomplete or required fiducial.

X The gantry will position over the standard pickup position.

X Illuminate (type and/or intensity) and teach (X/Y geometry) the pickup position fiducial for the black

blister tape accordingly.

X Test the pickup position fiducial with and without components in the tape.

 Feeder fiducial recognition

When components with a width of 08 mm or

wider are in the 0201(01005) 3x8mm S feeder

or when components which are narrower than

0.8 mm are in the 3x8 mm or 2x8 mm

standard S feeder.

The pickup position fiducial is automatically

generated from the CS body data.

The feeder fiducial from the pickup position is

derived from the construction offset. This is a

1.0 mm black machine circle fiducial.

ATTENTION:

This teaching is ONLY REQUIRED if the component sizes match the values specified above

and if these components need to be picked up from the black blister tape! (As of 2008, only one

such case is known.)
