A robotic tool picks and places a clinging part in an assembly. Two gripper jaws each have gripper fingers spaced apart from each other by a central spacing. The gripper jaws are movable between a grip position and a release position. The robotic tool also has an ejector. The ejector has a part pusher that is cling resistant and movable in the central spacings between a retracted position, and an eject position in which the cling resistant part pusher ejects the clinging part.
Based on the working principle of a horizontal plate precision metering device, the causes of seed damage and delivery precision of the existing
pusher and
ejector were analyzed and a new type of ball bearing
Pusher and
Ejector was developed at
Shivalik Alloys . Resulting in field and laboratory experiments showed that the ball bearing
Pusher and
Ejector improved metering performance and reduced seed damage.
