Abstract

A described assembling system 2 automatically inserts irregularly shaped components into power cards. A raw power card 1 that is to be populated with components is placed in either the left or right side of a card workstation 6. Switches that are mounted on card rails 7 signal the robot 4 that the card is in position to be populated. A robot gripper 5 picks up a tool 3 and locates the edge of the card and places the card in the correct position. Tooling pins 10 move upward to lock card 1 in the proper orientation. The gripper 5 returns the tool 3 to its holding place. (Image Omitted) The automatic component insertion works in the following sequence. Variously shaped components, i.e., heatsink assembly, transformers, inductors, connectors and large capacitors are picked up by the robot gripper 5 from gravity feeders 8.

Robotic Assembly of Power Cards

A described assembling system 2 automatically inserts irregularly shaped components into power cards. A raw power card 1 that is to be populated with components is placed in either the left or right side of a card workstation 6. Switches that are mounted on card rails 7 signal the robot 4 that the card is in position to be populated. A robot gripper 5 picks up a tool 3 and locates the edge of the card and places the card in the correct position. Tooling pins 10 move upward to lock card 1 in the proper orientation. The gripper 5 returns the tool 3 to its holding place.

The automatic component insertion works in the following sequence. Variously shaped components, i.e., heatsink assembly, transformers, inductors, connectors and large capacitors are picked up by the robot gripper 5 from gravity feeders 8. The components are positioned and inserted on the raw card 1 with a search pattern using the tactile sensors of the robot 4. When all components are in place, assembly is completed and the populated card is pushed out by the robot. The system has a printer that prints a report giving insertion times, component location offsets and rejected or missing components. The robot senses empty feeders by comparing the gripper 5 opening at the time of component pick up to the expected gripper opening stored for a valid component. Components that won't insert after a complete search pattern are disposed of at a common reject fix...
