CHAPTER 38 STINGER
OVERVIEW
Stinger is a glue dot dispenser module attached to the camera carriage. The
dispensed adhesive is used to hold larger mass components, which may as a
result of transportation, or where under components are used, move after
placement.
After a product has been printed, Stinger dispenses adhesive in a pre-pro-
grammed pattern onto the product’s surface. A laser can be programmed to
take a measurement at various locations on the product; these measurements
are used to check that the dispense gap is maintained, even where product
warpage exists.
Operation Regulated air is supplied to the rear of the syringe, forcing an internal plunger
to compress the adhesive. The auger body fills with adhesive and the auger
valve screw (Archimedes screw) is rotated, providing a stirring motion that
‘works’ the adhesive; this action disperses any air bubbles that may be present.

STINGER
OVERVIEW
Figure 38-1 Exploded View of the Dispense Mechanism
The unit can be programmed to purge the contents of the syringe, ensuring
consistency, prior to a production run. Externally, a consumable level sensor
detects the level of the adhesive in the syringe and warns the operator when
the level is low. A laser can be programmed to take height readings across the
top surface of the product; the information gained, is used to adjust the dispense
height, thereby increasing the consistency during the dispense cycle.
For detailed set up and operation procedures refer to manual, Stinger, a guide
to adhesive dot dispensing - Part Number 88198825-01.
