Abstract

The system provides automatic assembly of logic and power cards with oddly shaped components that previously required manual assembly. The operation utilizing the robot to perform component insertion is as follows: I. The robot 10 picks up the first alignment pin and slides the card 12 into position utilizing the pin. II. The robot inserts the first, second and third alignment pins through the card 12 and feeder rails 14. III. The robot controller causes the feeder bank 16 to raise and lower so that the parts to be inserted are gravity fed and, alternately, are in a position to be picked up by the robot. IV. The component insertion utilizing the robot proceeds as follows: 1. Various-size sockets are picked up by the robot from the feeder guides 18, are oriented, and then inserted on the card. 2.

Robotic Component Insertion

The system provides automatic assembly of logic and power cards with oddly shaped components that previously required manual assembly. The operation utilizing the robot to perform component insertion is as follows: I. The robot 10 picks up the first alignment pin and slides the card 12 into position utilizing the pin. II. The robot inserts the first, second and third alignment pins through the card 12 and feeder rails 14. III. The robot controller causes the feeder bank 16 to raise and lower so that the parts to be inserted are gravity fed and, alternately, are in a position to be picked up by the robot. IV. The component insertion utilizing the robot proceeds as follows: 1. Various-size sockets are picked up by the robot from the feeder guides 18, are oriented, and then inserted on the card.
2. The various components, such as cylindrical capacitors and diodes, are picked up by the robot from the feeder guides and positioned in the registration block 20. These components are then oriented and positioned on positioned on the card. 3. The feeder banks 16 are again raised to move further components into position by gravity,thus allowing the robot to access the parts at a given point to save physical space. 4. Steps 1 and 2 are repeated until the full assembly of the card is completed. The card 12 is removed by the robot by removing the three alignment pins and utilizing one of the pins to push the board out of the work area. The card 12 decelerates as it is pushed by the robot to its assembly position. The variable linear speed obtained is accomplished through a camming motion created by rotating the theta 2 axis only, thereby allowing no card overshoot to occur. Since the manufacturing techniques of the components do not ensure accurate housing to lead relationships, the pins must be conformed in a registration block 20 while the gripper 22 retains the housing. This registration positions the leads accurately with r...
