▪ 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 angle.

Detailed rotation process at DP station, positioning into

placement angle

▪ 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 posi-

tion 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 actu-

al position deviation is within the permitted tolerance.

9.2.11 Optical Nozzle State Recognition (Nozzle Scanning)

Optical Nozzle State Recognition (Nozzle Scanning)

1. After placing the first board the nozzle scanning is activated:

– Alle Nozzles which have been activated for nozzle scanning are tested by the Be (Nozzles ex-

ample 901, 904, 905, 906, 907, 911, 914, 925).

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

– If the nozzle outline or the nozzle air inlet limit deviates from the defined construction, a 'nozzle

is dirty' error will be issued.

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

ponent has slipped.

3. The frequency of the tests can be defined The standard fequency is after 350 The test is automati-

cally carries out after a PCB placement is completes and during a reference run

Air Blast Control During Placement

Diese Funktion nutzt eine für den TWIN- und C&P20-Kopf nötige Programmiermöglichkeit für den Blas-

druck beim Bestücken auch für den C&P6/12-Bestückkopf als Zeitsteuerung für das Blasluftventil wie

folgt aus:

Air blast control during placement with the C&P6/12 head

▪ Entering "0" means: air blast valve will not be switched on. (Do not use!)

▪ (1) Entering "1-50" means: air blast valve will be switched off before the stepping motor is started.

(Not recommended as the air blast is then too short to reliably place the component.

▪ (2) Entering "51-150" means: air blast valve will be switched off at a 90° rotation of the stepping mo-

tor.

▪ (3) Entering "151-255" means: the air blast valve will be switched off when the light barrier is up or

when the stepping motor rotates by 180°.

▪ No entry "----" (from conversion of 501/502 to 503) means: switching as in 3 (standard).

Detailed rotation of DP station, 3. Swivel out

▪ The command to start swiveling out is the end posi-

tion 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 ro-

tates by 90° in a counterclockwise direction, to swivel

out.

▪ Diagram 2 shows the status when swiveled out.

Sie können diese Funktionen keinesfalls dazu nutzen um Zeit einzusparen. Ihre

Im Ablauf einer Bestücksequenz des C&P12 wird geprüft ob das Vakuumsystem in Ordnung ist bzw. es

wird geprüft ob das BE korrekt an der Pipette vorhanden ist.

9.2.13.1 Component Sensor Functional Description

Component Sensor Functional Description

The component sensor for the C&P12 head functions according to the shadow casting principle, to de-

termine the height of the component on the nozzle. This means that the nozzle shadow is compared to

the shadow caused by the nozzle with component.

Measurement is performed "on the fly", during star rotation.

Conditions for measurement:

▪ The component sensor is fitted.

▪ The component sensor is configured in SIPLACE Pro and SITEST.

▪ The nozzle is longer than 12 mm and casts a shadow in the sensor.

▪ The component on the nozzle is still within the 5mm measuring range

(nozzle length in sensor + component height < 5 mm).

▪ The component has been selected for measurement in the component sensor (in order to measure

either the component presence or component height).

Component presence check modes (SIPLACE Pro programming)

Measurement procedure:

▪ Compare the "length of empty nozzle before pickup" with the "nozzle length during reference run".

▪ Compare the component on the nozzle before placement (depends on operating mode) with the

"length of the empty nozzle before pickup".

▪ After 350 head cycles, the "nozzle length during reference run" is measured again.

NOTICE! The BE sensor C&P12-Head does not measure 0,4x0,2 mm (01005).. The empty

nozzle is scanner measured before and after placement in this way the component placement is ensured
