Automated access method and device for use with lead frame magazine end cover plates during IC packaging process

摘要

An automated access device for lifting and placing back the end cover plates of lead-frame magazine during IC packaging process. It includes: (a) a 3-axis robotic arm a plurality of single-axis robots, adapted to carry out a positioning by horizontal and vertical motions; (b) an end cover plate temporary storage shelf, adapted to temporarily store a plurality of end cover plates removed from the magazine; (c) a guiding mechanism, adapted to provide positioning assistance of the end cover plates; and a gripper mechanism, installed in each the robotic arm. The gripper mechanism includes: (i) a suction disc; (ii) a first driver adapted to drive the suction disc to adhere to the end cover plates (iii) a second driver adapted to adjust the position of the suction disc; and (iii) a fixture cylinder having a first gripper adapted to position and fix the end cover plates to assure correct positioning and prevent the end cover plates from dropping during the motion of the robotic arm.
