Abstract

Programmable Read-Only Memory (PROM) modules must be burned (written) with microcode, tested, and labelled. PROM burning is an ideal robotic application because PROMs are designed to be handled by automated equipment, but the existing equipment cannot apply labels. An IBM 7535 Robotic Manufacturing System is connected to a communications port on an IBM Personal Computer (PC). The PC is connected by other ports to the PROM burning equipment. The PC is the manufacturing cell controller. The robot's digital input points are connected to sensors, and its digital outputs are connected to actuators, such as air solenoids. In this way, the PC can control the action within the cell, and react intelligently to a variety of manufacturing problems.

Robotic Burn and Test of PROM Modules

Programmable Read-Only Memory (PROM) modules must be burned (written) with microcode, tested, and labelled. PROM burning is an ideal robotic application because PROMs are designed to be handled by automated equipment, but the existing equipment cannot apply labels. An IBM 7535 Robotic Manufacturing System is connected to a communications port on an IBM Personal Computer (PC). The PC is connected by other ports to the PROM burning equipment. The PC is the manufacturing cell controller. The robot's digital input points are connected to sensors, and its digital outputs are connected to actuators, such as air solenoids. In this way, the PC can control the action within the cell, and react intelligently to a variety of manufacturing problems. The PROM dispensers and the robot gripper are modifications of parts taken from a commercially available module-insertion machine. The gripper has had a retractable suction head added to pick up and apply labels. It is also used to handle PROMs after they have been burned. The PC can monitor and control the process quality through the rudimentary intelligence of the PROM burners. The PC can act on the results of verification testing after burning by segregating any bad modules. Labels carried on a backing tape are dispensed from a specially designed mechanism. The labels, on their backing material, are passed over a knife edge where the backing material is pulled down, away and backwards. The...
