ELEMENTS
The assembly comprises:
• Auger and auger drive motor
• 10cc Syringe and dispense nozzle
• Z-axis motor
• Laser light sensor
• Consumable low level sensor
• Pneumatic regulator
• Electrical and pneumatic control interface
• Purge Station (optional)
The syringe attaches to an auger valve at the outlet end and to a pneumatic
supply at its input. A ‘C’ shaped clamp holds the unit in position at the rear and
it is fixed at the front with a plastic clamp screw.
A slightly positive air pressure is pulsed at the rear of the syringe to ensure the
auger valve is not starved of adhesive and a consistent supply is maintained.
The pulses are programmed in software to correspond with the auger feed
movement phases of the dispense cycle.
Adhesive Delivery
Mechanism
The delivery mechanism consists of an Archimedes screw fitted in the auger
valve. A stepper motor and pulley assembly (not shown) rotate the screw in the
auger valve. This action, combined with the positive air feed at the rear of the
syringe, ensure a consistent level of dispense when used in the correct operat-
ing conditions (temperature/humidity). The auger is purged with adhesive after
a syringe has been replaced.
The drive rotates for a pre-programmed number of steps in the feed direction.
The adhesive flows out of the nozzle onto the product surface, forming a dot. At
the end of each dispense, the motor can be reversed, this allows the auger to
draw adhesive back into the nozzle to avoid ‘stringing’. The number of motor
