Operation
Operation Overview
The Switch 3D gun dispenses ribbons of material onto a
substrate. The height and width of the material bead is
dependent on the flow rate of the material and the
speed of the robot movement. The size of the bead can
also be determined by the size of the nozzle. See
determine settings of the Switch 3D Gun.
Pressure Relief Procedure
Follow the Pressure Relief Procedure whenever
you see this symbol.
This procedure describes how to relieve pressure from
the Switch 3D Gun. See your supply system manual for
instructions on relieving pressure from the entire
system.
1. Shut off the material supply.
2. Position the Switch 3D Gun into a grounded metal
pail to relieve the fluid pressure.
3. Relieve all air pressure in the air lines by shutting off
the Customer supplied bleed valve. See F
4. If the nozzle tip or material hose is clogged or if
pressure has not been fully relieved after following
the steps above, very slowly loosen the customer
supplied material hose from the 3/8 in. BSPP inlet
fitting (704), (see F
Flush the Switch 3D Gun
•
Flush at the lowest pressure possible. Check
connectors for leaks and tighten as necessary.
•
Flush with a fluid that is compatible with the fluid
being dispensed and the equipment wetted parts.
Setup
1. With the Switch 3D Gun fully primed and cable
connections integrated into the robot control
system, the Switch 3D Gun is ready for dispensing
material onto the substrate.
2. Calculate the flow rate by the required height and
width versus the robot speed.
3. Adjust the material control system supplied with the
robot to the required flow rate.
4. Program the robot with the desired nozzle used to
dispense the material. The nozzle must be
perpendicular to the substrate.
5. Run the program and validate the height and width
of the bead.
6. The flow rate, robot speed, and nozzle size can be
adjusted to achieve the desired height and width of
the material bead.
7. Nozzle distance from target can affect the quality of
the bead. The further the nozzle is from target the
more air can be trapped between the bottom of the
bead and substrate. See
8. After the correct height, width, and quality of the
bead is confirmed, the Switch 3D Gun is ready for
dispensing.
This equipment stays pressurized until pressure is
manually relieved. To help prevent serious injury from
pressurized fluid, such as skin injection and splashing
fluid, follow the Pressure Relief Procedure when you
stop spraying and before cleaning, checking, or
servicing the equipment.
To avoid fire and explosion, always ground equipment
and waste container. To avoid static sparking and
injury from splashing, always flush at the lowest
possible pressure.
