6.2.3 Vacuum check

Vacuum check

▪ After the CAN bus processor for the vacuum/air blast distributor has booted, the vacuum/air blast

distributor is initialized. This means that vacuum/air blast generator is adjusted to ensure that neither

vacuum or air blast is generated at the nozzle.

▪ The Gantry axes move the Twin-head to the reject position.

▪ Over the reject box the Vacuum-, air blast generator switch to air blast to reject components and

check the air blast.

▪ The vacuum/air blast generator now switches over to vacuum and the open vacuum at both seg-

ments (X and D3 machine, D1/D1i: one Twin segment) is measured*.

▪ After measurement, the pressure is adjusted back to 0 bar.

▪ The vacuum reference run has now been completed for the Twin head.

* The closed vacuum value for the Twin segments relates to the calibration value which was determined

in SITEST.

Reference run D-axis

1. Incremental glass scale D-axis

2. Incremental encoder

3. Zero pulse on the incremental glass scale

Then the D-axis (turning axis) executes the reference

run.

The D-axis runs to the zero pulse of the D- axis encoder.

The zero point correction value will be loaded. The D-axis

moves to the reference position, in accordance with the

prefix shown before the value.

Reference run completed! This is followed by the gantry

reference run (see Section Gantry).

Measure nozzle height

With this function we check the correct nozzle type which

is programmed. The nozzle length is taken to calculate

the pick up and placement height for the following place-

ments.

1. Top of fixed conveyor side

2. Z motor

3. Vacuum - air blast distribution

► The gantry moves the placement heads above the

fixed conveyor side.

► The Z axis positions module 2 (X/D3 machine) down-

wards.

► The travel range of the Z axis is taken to calculate the

Twin head height in relation to the nozzle type.

► Now the same happen with module 1.

► The maximum length tolerance is 0,4 mm: If the

length difference is too high an error message is dis-

played.

NOTICE

Both modules are measured at the same position of the PCB conveyor!

This Twin head reference run is performed parallel to the C&P head reference run in the other

placement area.
