The major components of the mechanical ceramic substrate centering unit are the X-slide unit with
centering jaws which consists of a stop rail and stop unit at the front of the centering unit, a flat
cylinder with 5.6 bar compressed air connection, resetting spring, and inductive proximity switch
at the back (see Fig 2.3 - 3), that signals the condition "Centering unit open".
The triggering of the mechanical ceramic substrate centering and the monitoring of the proximity
switch are activated by the conveyor control. If an error occurs, the message "Error ceramic sub-
strate centering 1 / 2" is output at the station’s operating interface (see Section 2.3.6).
During the placement run, the substrate - like a PCB - is transported into the processing area
1 / 2 or 4 / 3 where it is recorded by the ultrasonic sensor. The stopper thereupon moves out, prep-
ositioning the substrate in X-direction, and the stopper then moves back.
When the ceramic substrate centering unit is open (in which state compressed air is present at
the ceramic substrate centering unit), it is lifted into the area of the substrate by the lifting table
and the signal "Lifting table at top" is triggered.
The mechanical X-centering follows: The pressure in the centering unit drops to zero. As a con-
sequence, the X-slide unit of the ceramic substrate centering unit moves forward and centers the
substrate in the X-direction (= transport direction) with the help of a tension spring between the
two ball bearings of the stop rail and the roller on the stop unit.
Following position recognition and completion of placement, the pressure of the compressed air
is exerted, opening the mechanical substrate centering unit.
The inductive proximity switch on the centering unit is tripped (switch signal => 1). When this sig-
nal "Ceramic substrate centering unit open" is received, the lifting table moves down with the open
centering unit and thus moves out of the path where substrates are transported.
The substrate is transported into the next conveyor area (intermediate conveyor / output con-
veyor).
