Abstract

A gripper has been developed for picking and placing semiconductor modules during manufacturing operations. The device makes it possible to pick or place three modules at a linearly oriented hopper track station, change their relative orientation, and then place or pick them at a turntable station. In the manufacturing process three linearly arranged hopper tracks at the linear station (Fig. 1) have modules placed in either the pass 1 or fail 2 locations or picked from the untested 3 location. At the circular station, modules 4 are tested in the test socket 5 as the turntable 6 rotates (7). The task of the gripper is to place and pick the modules, as required, for testing and removal.

Variable Geometry Multiple Robotic Gripper

A gripper has been developed for picking and placing semiconductor modules during manufacturing operations. The device makes it possible to pick or place three modules at a linearly oriented hopper track station, change their relative orientation, and then place or pick them at a turntable station. In the manufacturing process three linearly arranged hopper tracks at the linear station (Fig. 1) have modules placed in either the pass 1 or fail 2 locations or picked from the untested 3 location. At the circular station, modules 4 are tested in the test socket 5 as the turntable 6 rotates (7). The task of the gripper is to place and pick the modules, as required, for testing and removal.

The gripper has the capability of positioning the modules in either a linear orientation to accommodate the needs of the linear station or in a circular orientation to meet the needs of the circular station. The development consists of an air-actuated pivoting unit 8 (Fig. 3) with three modified commercial grippers 9 attached which act in parallel to grip the modules 10. Air cylinders 11, mounted back- to-back, provide the action to move the gripper assemblies at the outboard sides of the unit. Fig. 4 shows the air cylinders 11 in an extended position so that modules 10 will be held in a linear position by the gripper assemblies. Fig. 5 shows the cylinders 11 in a retracted position with the gripper assemblies 9 positioned s...
