US 12,655,837 B2 · Apparatus for peristaltically pumping liquid onto a rotating surface

Abstract

In one embodiment, an apparatus includes an actuator coupled to an end effector, the actuator configured to create relative rotation between the actuator and the end effector. The apparatus further includes one or more peristaltic-pump rollers coupled to the actuator. The end effector includes a liquid-storage chamber configured to store a liquid and a flexible tubing that includes: (1) an intake disposed within the liquid-storage chamber, (2) an outlet configured to dispense the liquid onto an outer surface of the end effector, and (3) a peristaltic section configured to compress against at least one of the one or more peristaltic-pump rollers as a result of the relative rotation between the actuator and the end effector.

Dependent claims

An apparatus comprising:

an actuator coupled to an end effector, the actuator configured to rotate the entire end effector relative to the actuator;
one or more peristaltic-pump rollers coupled to the actuator;
and
the end effector, comprising:
a liquid-storage chamber configured to store a liquid;
a flexible tubing comprising an intake disposed within the liquid-storage chamber, an outlet configured to dispense the liquid onto an outer surface of the end effector, and a peristaltic section configured to compress against at least one of the one or more peristaltic-pump rollers as a result of the relative rotation between the actuator and the end effector, wherein every portion of the flexible tubing is part of the end effector that rotates relative to the actuator.
