9.4.7 Calibrating the Twin Head

During initial setup or after replacement of a Twin module the Twin Head must be calibrated. This menu

measures the offset between the Twin segment and the PCB camera center.

X Put the nozzles 517 by hand on the segments of the P&P modules.

X Make sure that the first nozzle from the garages are empty and depend on this the filling level from

the nozzle changer are edited, This is necessary for calibration of the pickup height.

X Enter the nozzle "517" for both TWIN modules as active nozzle on the TWIN Head:

9.4.8 Mechanical Adjustment of the Z Axis Incremental Encoder

9.4.9 Vision DC/DC Converter

The function of the Vision DC/DC converter is to provide the 42V voltage supply for the stationary

cameras.

The 42V are use for the illumination of the stationary cameras.

When replacing the Vision DC/DC converter, observe the following settings, which depend on your

installation location (main/subdistributor).

9.4.10 Manual Lowering of Z Axis

The Twin head is designed for a placement force of 0.5 to 15 N (up to 30 N for the high force Twin head)

. The rotary axis needs to be very smooth-running, especially for low placement forces. Therefore, the

rotary axis is not constructed for traction forces.

NOTE:

The following calibration steps are performed automatically: - MA zero point, PCB camera,

calibration tool position, head height, TH calibration offset module 1 and 2, IC camera, (option

FC camera), nozzle changer.

NOTE:

The incremental encoder on the Z axis must be adjusted to a distance of 0.4 mm to the

incremental scale. Please adjust the incremental encoder parallel to the incremental scale.

After fitting, check the Z axis track signals (see Section Component Handling).

Since both segments of the Twin head are fitted at an angle of 180°, there are two different methods for

moving the Z axis downwards.

CAUTION:

When manually lowering the Z axis, the Twin head module can be easily damaged!

X Manual lowering may only be performed by trained personnel!

ATTENTION:

Before performing manual lowering of the Z axis, make sure the Z axis has been released at the

relevant axis controller board.

X When releasing the Z axis, the Z axis return cylinder moves upwards.

X If the axis is not released, the return cylinder will automatically move upwards when the Z axis

is manually lowered, which could cause injuries and damage to the placement head.

Lowering the Z Axis at P&P Module 1

To safely press the Z axis downwards, apply

manual pressure to the marked part of the return

unit driver.

Lowering the Z Axis at P&P Module 2

The Z axis can be moved downwards at segment

2 by taking hold of the carrier arm from both sides

and then pushing this down.

magazines are seated on a common support.

They are centered with two parallel pins and fixed

in place with two countersunk screws.
