ABSTRACT:
Apparatus are shown for handling molded leadframes comprising, in combination, a gripper portion for grasping a molded leadframe from atop a first magazine holding a first plurality of molded leadframes and for releasing the molded leadframe when placed atop a second plurality of molded leadframes in a second magazine, and a mover portion coupled to the gripper portion for moving the gripper portion back and forth in a substantially semicircular motion between the first and second magazines. The mover portion includes a linking member coupled to the gripper portion, a first member rotatably coupled at a first end thereof to the linking member, a second member rotatably coupled at a first end thereof to the linking member, and a driver portion rotatably coupled to an opposite end of each of the first and second members for moving the gripper portion in a back and forth, substantially semicircular motion between the first and second magazines. Note that while the driver portion is shown in two of several possible embodiments, each embodiment of the driver portion includes only a single driver to move the gripper portion back and forth in the substantially semicircular motion.
