Dipping plate with adjustable cavity depth (only for LDU 2 X with Auto Cavity
option)
The adjustable cavity of the Auto Cavity dipping plate consists of a movable cavity plate, which is
connected to the dipping plate body by a flexible seal.
Dipping plate top side:
1. Dipping plate
2. Cavity plate
3. Seal
On the bottom side of the dipping plate, the cavity plate is supported by two stop plates, which
define the lowest position of the cavity plate and also ensure mechanical stability during the dipping
process.

Dipping plate bottom side:
1. Dipping plate
2. Cavity plate
3. Stop plates
The Auto Cavity dipping plate allows for cavity depths from 0.01mm to 0.25mm with an adjust-
ment tolerance of ±10 µm. The maximum component size that can be used on this dipping plate is
15 mm x 25 mm.
NOTICE
All existing standard dipping plates with fixed cavity depths can also be used with the
LDU2X with Auto Cavity option.
3.2.6 Dip stroke plate
1. Electromagnets
2. Permanent magnets
3. Dip stroke plate
The dipping plate is held in place on the by four permanent magnets. Two electromagnets are used
for additional fixing dip stroke plate and check whether a dipping plate is fitted. The electromagnets
detect changes in the distance between dipping plate and dip stroke plate. This will be the case
when the dipping plate gets stuck to the park plate during the downwards movement.
NOTICE
Dipping plate not available
If the dipping plate does not fit properly, the dipping plate is not recognized and "plate not
available" is displayed.
Dip stroke plate for LDU 2 X with Auto Cavity option
The dip stroke plate of the LDU 2 X with Auto Cavity option is a special design with a height adjust-
ment mechanism. A vertically movable pusher block contacts the cavity plate and controls its ver-
tical position.

3.2.7 Axes
The LDU has two drive axes.
The squeegee axis moves the squeegee forwards and backwards.
1. Squeegee
2. Front bearing block
3. Spindle
4. Guide rail
5. Rear bearing block
6. Coupling
7. Motor
The lifting axis moves the dipping plate up and down:
1. Motor
2. Coupling
3. Dipping plate
4. Dip stroke plate
5. Guidance
6. Slide
7. Bearing block (base of park plate)
The maximum lift of the lifting axis is -8.5mm to +22mm (mechanical stoppers). The basic position
(determined by an inductive switch) is at -7.5mm. The squeegee is positioned at 0mm. The dip-
ping position is at +17.5mm. Squeegee and dipping position are determined by the pulse gener-
ator of the motor.
