3.8 Optional Equipment
Asymtek offers a wide range of options for fine-tuning your dispensing applications. This section
introduces options that are currently available for the Century C-740/C-741 Series Dispensing System.
3.8.1 Bar Code Recognition System
The Bar Code Recognition System uses a bar code label mounted on the workpiece to select the
appropriate coating sequence. The scanner, mounted on the conveyorized unit, reads the label, selects the
proper coating sequence within the ECXP software, and then executes the sequence.
3.8.2 Board Present Sensor
The Board Present Sensor, mounted on the Dispensing Head, registers the presence or absence of a
workpiece prior to dispensing. It initiates the coating sequence only when a workpiece is in place.
The Board Present Sensor is ideal for production environments where carriers are manually loaded. If a
carrier is not fully loaded, the system will detect the empty space and not dispense at that location. The
Board Present Sensor is factory configured at the time of system manufacture. It optimizes material usage
and minimizes cleanup.
3.8.3 Brush Box
The Brush Box mounts to the Conveyor and is used to clean the dispensing nozzle. The Brush Box
performs best with solvent-based materials, but can also be used with solvent-less fluids. Solvent is added
to the box, covering the bristles mounted to the bottom. At programmed intervals, the nozzle tip moves
back and forth in the solvent against the bristles to remove accumulated material. Advantages include:
Automatic nozzle cleaning with minimal operator intervention.
Improved dispensing consistency due to reduction of material buildup on the fluid applicator.
