Automatic Nozzle Cleaning
While dispensing fluids, the tip of the nozzle may collect a small deposit of fluid that could affect the consistency of dispense. Our automated nozzle cleaner can remove this drop of fluid ensuring a consistent dispense process. Cleaning the nozzle is done before the automated nozzle calibration routine, and can be programmed for the beginning of a program or at any time during a program. Systems with multiple dispense heads can benefit from multiple nozzle cleaners. Using multiple nozzle cleaners avoids potential contamination of a nozzle with a foreign fluid (non-conductive glue and conductive glue, for example).
Automated Needle Cleaning Sequence
The clamp nozzle cleaner - standard with all GPD Global automated platforms - uses a contact method that envelopes the end of a nozzle. When the nozzle is retracted, a wiping action is created leaving a clean nozzle tip for the dispense process. The nozzle moves incrementally along the length of the pad to avoid nozzle contamination. The system notifies the operator when the needle reaches the end of its pad length.
The Needle Cleaner tool-less design makes changing the wipes very easy. Simply remove the magnetic pad holders, remove the old pads, and insert new ones. Multiple styles of wipes (pad, paper) are available. The style needed depends on the type of fluid to be cleaned.
The Vacuum Nozzle Clean/Purge is recommended for the NCM5000 Jetting pump. The NCM5000 Jetting pump doesn't use conventional needle-type dispense tips, so vacuum is the best way to clean the nozzle tip. The vacuum nozzle clean/purge device is integrated into the calibration station. Vacuum pulls fluid from the pump tip into a tiny purge cup.
Vacuum nozzle clean/purge also works with standard types of needles. Use of the vacuum nozzle clean/purge is optional for Precision Auger and Volumetric PCD pumps. In some cases, you can use both vacuum nozzle clean/purge and the clamp nozzle cleaner. For fluids that tend to wick up the side of the nozzle, use vacuum clean/purge to keep the needle clean during the purge process while still using the clamp nozzle cleaner.
