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.
