2-6 Introduction
Front View Features
Following are short descriptions of the various parts and modules of the C-718SMT system
(Figure 2-1, Figure 2-2 and Figure 2-3). Detailed operation instructions for some features
are covered in other sections.
Computer System (computer, monitor, keyboard, mouse)
The Computer System is used to create and run dispensing programs with the Asymtek
dispensing software Fluidmove
®
for Windows NT (FmNT).
Control Panel
The Control Panel mainly uses membrane buttons. The Panel is organized to control certain
programming and run functions via three functional areas: Download Program Control,
Motion Control, and Safety Interlock Control. From the Panel you can move the dispensing
head, move the conveyor belts and rails, enable the Safety Interlock system, make an
emergency stop, check dispensing status, and adjust valve controls.
Conveyor
The specific type of conveyor and dimensions on your system may be customized for your
application. All dispensing systems with conveyors are SMEMA compatible. The Control
Panel and Fluidmove software control the conveyor. C-718SMT dispensing systems use belt
conveyors.
Conveyor Controller
The Conveyor Controller module monitors the SMEMA interface and controls the conveyor
indexing operations. The inputs and outputs are used for sensors, stop pins, bar clamps and
operation of the conveyor. For more information on the conveyor, see Section 4-Operation.
Dispensing Head
The Dispensing Head moves in the XYZ planes. It is controlled by the dispensing system
software and the Control Panel. The fluid pump, vision system, height sensor, and needle
heater are attached to the Dispensing Head.
Dual-Action Dispensing Head (option)
An optional Dual-Action Dispensing Head makes it possible to dispense a second fluid
during a single dispensing cycle. It is controlled in the same manner as the single
Dispensing Head.
EMO
In emergencies, this large, red “mushroom” button shuts down power to the Control Panel,
the dispensing mechanics, conveyor, and temperature controller. It does NOT shut down
power to the computer, monitor.
Fluid Pressure Gauge and Regulator
The Fluid Pressure Gauge indicates the air pressure supplied to the syringe. Systems
equipped with a Dual-Action Dispensing Head have an additional fluid pressure gauge for
the second pump. The Fluid Pressure Regulator is located underneath the front hood of the
system. See the appropriate fluid pump manual for the recommended setting for your pump.
The maximum recommended setting is 2.1 kg/cm
2
(30 psi).
Fluid Pump
The fluid pump (also referred to as a “valve” or “jet”, depending on the type) dispenses the
fluid onto the part. It mounts on the dispensing head, and holds the syringe of dispensing
fluid. For more information, see the appropriate fluid pump manual.
