3-6 Component Description
X-1020 Dispensing Chamber Features
Below are functional descriptions of X-1000 Series Dispensing System components shown in Figure 3-3.
1. Dispensing Head`
The Dispensing Head is mounted on the X-beam and is moved by a positioning system in the X, Y, and
Z-axes. It carries the Dispensing Valve to a precise position over the workpiece in the dispense station of
the Conveyor. The Camera and Height Sensor (option) are also mounted on the Dispensing Head.
2. Electric/Pneumatic Bulkhead
The bulkhead consists of a sheet metal plate that supports electrical and pneumatic connectors for
accessories on the Dispensing Head. The bulkhead for Dispensing Valve 1 is on the left side of the
Dispensing Head and the bulkhead for Dispensing Valve 2 is mounted on the right side of the Head.
3. Camera and Lens
The Camera and Lens are part of the Vision System. They are mounted on the Dispensing Head and are
used to view work surfaces in the dispensing chamber.
4. Red/Blue Diffuse On-Axis Light
The Diffuse On-Axis Light, mounted on the Dispensing Head, provides variable red and blue LED lighting
for the Camera. Adjusting the light color and intensity improves video display contrast that results in
accurate fiducial identification on the workpiece.
5. Needle Heater
The Needle Heater is an RTD-controlled heating element attached to the needle on DV-7000 and
DP-3000 Dispensing Valves. The Needle Heater heats the dispensing fluid to maintain a consistent
viscosity and flowrate.
6. Dispensing Calibration Module (DCM)
The Dispensing Calibration Module on the Axiom X-1020 consists of the Weigh Station, Purge Station,
fiber-optic and tactile Needle Sensors, and a ceramic tile substrate.
6a Needle Sensor
The Needle Sensor includes a fiber-optic sensor that measures Dispensing Valve needle position in
the X- and Y-axes and a tactile sensor that measures needle position in the Z-axis. The FmNT
software uses this information to automatically compensate for changes in needle location. This
allows you to change needles and continue production without reprogramming the system.
6b Weigh Station
The Weigh Station is a location on the X-1020 Dispensing System where a scale measures the
weight of dispensed fluid and sends the information to the FmNT software for mass flow calibration.
6c Purge Station
The Purge Station is a location at the front of the dispensing chamber where the dispensing needle
is cleaned and the Dispensing Valve is automatically purged at user-defined intervals. A disposable
plastic cup inside of the Purge Station catches the dispensed fluid.
7. Heater Tooling (Option)
Heater Tooling (contact or impingement) is an option available on systems performing applications that
require heat. Contact Heaters have vacuum ports to hold the workpiece against the heated surface
during heating. Impingement Heaters blow heated air onto the underside of the workpiece from below
without direct contact. Heaters can be installed at up to three Conveyor stations.
