1. The vacuum is measured twice at the reference point: once with closed and once with open valve,

while air flows through the nozzle.

2. The value with closed valve depends on the ambient pressure and may vary significantly, according

to the local weather conditions and altitude. The higher the ambient pressure, the lower the vacuum

at closed valve.

3. The value by open valve depends on the nozzle size and condition. The smaller the nozzle, the

greater the open valve value will be. A contaminated or blocked nozzle will also give a higher valve.

4. The difference between the open and closed nozzles has been preset by the line computer as an

ideal case minimum value. This value is different for all nozzle types e.g. 120 mbar for 714, 704, 914

and 904 nozzles. If these values are not achieved, the error message "Vakuumdifferenz offen-

geschlossen zu gering" (vacuum difference open-closed is too low) will appear.

5. The threshold for component acceptance is also set now. In this case we have a value of 700 mbar

when the nozzle is open and a value of 900 mbar when the nozzle is closed. The calculation is

performed as follows:

Threshold = (900(closed) - 700(open))= x 0.2 + 700(open) = 200 x 0.2 + 700 = 740

5.3.10 Measuring Nozzle Lengths for Component Recognition by the Component

Sensor

The component sensor option can only be used with machine stations SW 503 or higher and only with

12 nozzle C&P placement heads.

If the CO sensor option is installed on the C&P12, the following will be performed during the vacuum

reference run:

 The length of the nozzle in the IR beam will be measured during star revolution.

 The SIPLACE Pro/LC defines which nozzle type can be measured (nozzle lengths longer than

12 mm). Nozzle setup on the placement star triggers measurement.

 Before pickup, the length of the empty nozzle is compared to the value measured during the

reference run.

 During the placement process, component recognition refers to the empty nozzle measurement

value before placement is performed.

5.3.11 Height reference run

With this function, we check whether the fitting on the sleeve is correct and whether the correct nozzle

type (set by the placement program) is programmed. The nozzle length is taken to calculate the pick up

and placement height for the following placements. This height reference run is not dependent on the

nozzle length measurement in the CO sensor!

Legend:

1. Top of the fixed conveyor side

2. First step with segment 1 for measure the

nozzle height.

3. Last step with segment 6 (12) for measure the

nozzle height.

 The gantry moves the placement heads above

the fixed conveyor side.

 The Z- axis runs down, and all nozzles touch

the transport rail.

 Nozzle 1 defines the reference length.

 All segments are measured according to there

specific length reffering to nozzle 1.

 The maximum length tolerance is 0,4 mm: If

the length difference is too high an error

message is displayed.

NOTE: Exception:

special nozzle with type number X9X are only measured (there is no length

specification).
