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 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.

Elements The assembly comprises:
• Auger and auger drive motor
• 10cc Syringe and dispense nozzle
•Z-axis motor
• Laser light sensor
• Consumable low level sensor (not shown)
• Pneumatic regulator
• Electrical and pneumatic control interface
• Purge Station (optional) (not shown)
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.
The control interface is mounted on the panel at the rear of the printer. It
provides all the electrical and the pneumatic control functionality. An air pres-
sure regulator sets pneumatic pressure.
