9.2.21 Detailed Rotation of DP Station 1. Swivel In

9.2.22 Positioning into Pickup Angle

 Diagram 1 shows the initial position (state after

reference run).

 From the initial position, the stepping motor

rotates by 90° for swivel-in.

 The DP station swivels in and contacts the

sleeve (incremental disk).

 The stepping motor is monitored by the light

barrier on the cam disk.

 Diagram 2 shows the status after swiveling in.

 This is the start command for the DP axis

drive.

 The DP axis positions the segment to the

relevant zero pulse and checks the signal level

at a distance of 3 digits.

 An end position signal is emitted if the actual

position deviation is within the permitted

tolerance.

 There is no difference between the 0° and

180° or 90° and

90° pickup angles.

9.2.23 Positioning into Placement Angle

9.2.24 Detailed rotation of DP station, 3. Swivel Out

 When positioning begins, the actual position of

the axis is set to 0 by setting the position

counter of the DP axis to 0.

 The DP drive is operated in relative positioning

mode.

 The DP axis starts to move towards the target

position which is calculated from the station

calibration values, the line computer

programming values and the centering values

of the placement procedure.

 An end position signal is emitted as soon as

the actual position deviation is within the

permitted tolerance.

 The command to start swiveling out is the end

position signal from DP positioning.

 The DP drive is still located at the sleeve.

 Diagram 1 shows the status when swiveled in.

 The stepping motor is controlled by the light

barrier on the cam disk.

 From its swiveled-in status, the stepping motor

rotates by 90° in a counterclockwise direction,

to swivel out.

 Diagram 2 shows the status when swiveled

out.

Placement Procedure Optical Nozzle Query

9.2.25 Optical Nozzle Query

1. After placement of the first board, the nozzle request is enabled:

– All nozzles listed for optical checking will be measured by the CO camera (nozzles such as 901,

904, 911, 914, 925).

– From SW 601, these can be found in the nozzle.lib.xml

– If measurement detects a light point of a defined size and brightness, the machine will issue the

message "nozzle worn down or contaminated".

2. Due to the low component height, small nozzles may touch the soldering paste or adhesive if a

component has slipped.

3. The number of components per segment (number of head cycles), after the next nozzle query has

been performed, should be adjusted to the customer's process requirements. This test is always

performed after board processing has been completed.

4. Another option can also be set:

– Nozzle scanning is not a fatal error and although the machine will show the error, it will not stop.

9.2.26 Air Kiss Control During Placement

This function takes a programming option which was designed for the TWIN and uses it as follows for

the C&P placement head.

Air kiss control during placement

 Entering "0" means that the air kiss valve will not be switched on.

 (1) Entering "1-50" means that the air kiss valve will be switched off when the stepping motor starts.

 (2) Entering "51-150" means that the air kiss valve will be switched off when the stepping motor

rotates by 90°.

 (3) Entering "151-255" means that the air kiss valve will be switched off when the light barrier is up

or when the stepping motor rotates by 180°.

 No entry "----" (the conversion 501/502 to 503 means switching procedure as in (3) (standard).

Air kiss control for place back (do not reject)

 (4) Entry and description as in (1)

 (5) Entry and description as in (2)

 (6) Entering "151-255" means that the air kiss valve will be switched off when the stepping motor

rotates by 180°.
