Abstract
The resin dispenser comprises a support frame, a probe with an adjustable loading volume mounted on the support frame and connected to a vacuum source, a hopper for containing a resin slurry, a holder for retaining one or more containers to be loaded at a loading position, a translation means for moving the probe from the hopper to the container, a fluid circulation pump and an air pump for circulating fluid in the hopper, and at least one control device. The hopper includes a means for continuous circulation and replenishment of solvent with a large reserve of resin, and has a small volume from which the resin is extracted. The method for dispensing comprises drawing resin from a dispenser trough in the hopper into the loading volume using a vacuum, moving the probe to the loading position, then activating an air actuator which expels a resin pellet from the probe into the container by initiating movement of the inner and outer tubes that define the loading volume.
