Dispensing Needle Cleaning

Dispensing Needle 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 nozzle cleaner 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.

Wipe Styles

The Needle Cleaner tool-less design makes changing out the wipes very easy when it's time to replace them. Multiple styles of wipes (pad, paper) are available. The style needed depends on the type of fluid to be cleaned.
