Patent ID: 8062434

Claim:
A cleaning device to clean a plurality of nozzles of a surface-mount technology (SMT) machine, each of the plurality of nozzles comprising a hollow pipe, a baffle-board, and a sucker in communication with the hollow pipe, the cleaning device comprising: a first cleaning container defining an first opening in a bottom thereof, a first air injecting hole to allow airflow into the first cleaning container, and a fluid injecting hole spaced from the first air injecting hole; a supporting board connected to the bottom of the first container, and defining a plurality of first through holes to fix a plurality of sealing members so as to fix the plurality of nozzles; a filtering member located at a bottom of the supporting board; a second cleaning container connected to the filter member, and operable to receive cleaning fluid, wherein the second cleaning container defines a third opening at a top thereof, a second air injecting hole in a sidewall adjacent to the third opening of the second cleaning container to allow the airflow into the second cleaning container, and a fluid outgoing hole structured to release the cleaning fluid in the second cleaning container; and a connection member to connect the fluid injecting hole of the first cleaning container and the fluid outgoing hole of the second cleaning container, and to switch on or off communication between the first cleaning container and the second cleaning container; wherein injection of air to the first cleaning container and the second cleaning container allows the cleaning fluid to circularly flow through the second cleaning container, the connection member, the first cleaning container, the supporting board, and the filtering member under air pressure generated by the airflow so as to clean the plurality of nozzles.
