Ultrasonic cleaning system

An ultrasonic cleaning system, comprising:

• a cleaning tank containing a cleaning liquid and having a first opening and a second opening in a top wall thereof;
• a first moving and holding device configured to move a first carrier into the cleaning tank through the first opening and hold the first carrier in the cleaning tank, a plurality of fiber optic ferrules are mounted on the first carrier and are immersed in the cleaning liquid when the first moving and holding device holds the first carrier in the cleaning tank, the first moving and holding device comprising:
• a first carrier holder adapted to hold the first carrier;
• a first lift mechanism arranged on a first side of the cleaning tank and configured to move the first carrier holder up and down along a vertical axis;
• a first horizontal connection plate attached to a top of the first lift mechanism and extending toward the cleaning tank;
• and
• a first cover plate connected to the first horizontal connection plate and adapted to close or expose the first opening in the top wall of the cleaning tank;
• a second moving and holding device configured to move a second carrier into the cleaning tank simultaneously with the first carrier and through the second opening and hold the second carrier in the cleaning tank, the second moving and holding device comprising:
• a second lift mechanism arranged on a second side of the cleaning tank, opposite the first side of the cleaning tank;
• a second carrier holder adapted to hold the second carrier;
• a second horizontal connection plate attached to a top of the second lift mechanism and extending toward the cleaning tank;
• and
• a second cover plate connected to the second horizontal connection plate and adapted to close or expose the second opening in the top wall of the cleaning tank;
• and
• an ultrasonic wave generator mounted in the cleaning tank and adapted to emit an ultrasonic wave into the cleaning liquid to clean the fiber optical ferrules immersed in the cleaning liquid.

An ultrasonic cleaning system, comprising:

• a cleaning tank containing a cleaning liquid and having at least one opening in a top wall thereof;
• a first moving and holding device configured to move a first carrier into the cleaning tank through the at least one opening and hold the first carrier in the cleaning tank, a plurality of fiber optic ferrules are mounted on the first carrier and are immersed in the cleaning liquid when the first moving and holding device holds the first carrier in the cleaning tank, the first moving and holding device comprising:
• a first carrier holder adapted to hold the first carrier;
• a first lift mechanism configured to move the first carrier into the cleaning tank;
• a first horizontal connection plate attached to a moveable end of the first lift mechanism and extending toward the cleaning tank;
• and
• a first cover plate connected to the first horizontal connection plate and adapted to close or expose at least a portion of the at least one opening in the top wall of the cleaning tank;
• a second moving and holding device configured to move a second carrier into the cleaning tank through the at least one opening and hold the second carrier in the cleaning tank, the second moving and holding device comprising:
• a second lift mechanism configured to move the second carrier into the cleaning tank;
• a second carrier holder adapted to hold the second carrier;
• a second horizontal connection plate attached to a moveable end of the second lift mechanism and extending toward the cleaning tank;
• and
• a second cover plate connected to the second horizontal connection plate and adapted to, with the first cover plate, close or expose the at least one opening in the top wall of the cleaning tank;
• and
• an ultrasonic wave generator mounted in the cleaning tank and adapted to emit an ultrasonic wave into the cleaning liquid to clean the fiber optical ferrules immersed in the cleaning liquid.
