3-4 Component Description
X-1010 Dispensing Chamber Features
Below are functional descriptions of X-1000 Series Dispensing System components shown in Figure 3-2.
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. Electrical/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 compact, high resolution, black and white Camera and its vibration-resistant 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 (DOAL), 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 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.
6. 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. Look Up Board Sensor (X-1010)
Optical Board Sensors mounted under the front Conveyor rail detect the presence of the workpiece at
each Conveyor station. Depending upon system configuration, there may be as many as two Board
Sensors mounted along the length of the Conveyor rail.
8. Stop Pins
Stop Pins are pneumatic devices that physically stop the workpiece at a specific Conveyor station. There
may be as many as two Stop Pins attached to the rear Conveyor rail.
9. Height Sensor
The Height Sensor is a device that measures substrate height and sends a signal to the system
Computer. The height information is used to position the dispensing needle at an exact distance above
the workpiece surface. A Tactile Height Sensor is standard. A Class 2 Laser Height Sensor is optional.
