Abstract

This capacitor handling system is a parts feeding mechanism that automatically transfers tantalum capacitors from plastic shipping tubes 10 to a precision discharge track 12. Plastic shipping tubes 10 that contain two rows of capacitors are manually stacked in the magazine assembly 14. The first row of capacitors (those in the bottom tube) is automatically aligned between the driver assembly 16 and the discharge track 12. Air motor 18 is activated and drives spool 20 in a clockwise direction. As the spool 20 rotates, it drives spring steel band 22 through the tube 10. The band 22 pushes capacitors through the tube and into the discharge track 12. The capacitors hit a stop at the end of the track 12 and await removal by a robot (not shown). The first four capacitors in the track 12 are retained by four sets of fingers.

Automatic Capacitor Handling System

This capacitor handling system is a parts feeding mechanism that automatically transfers tantalum capacitors from plastic shipping tubes 10 to a precision discharge track 12. Plastic shipping tubes 10 that contain two rows of capacitors are manually stacked in the magazine assembly 14. The first row of capacitors (those in the bottom tube) is automatically aligned between the driver assembly 16 and the discharge track 12. Air motor 18 is activated and drives spool 20 in a clockwise direction. As the spool 20 rotates, it drives spring steel band 22 through the tube 10. The band 22 pushes capacitors through the tube and into the discharge track 12. The capacitors hit a stop at the end of the track 12 and await removal by a robot (not shown). The first four capacitors in the track 12 are retained by four sets of fingers. The fingers are programmed to allow removal of any combination of capacitors (four maximum) depending on product requirements. The air motor is temporarily shut off to relieve pressure on the capacitors. The solder head, on the robot, comes down and engages the first four capacitors. The appropriate number of retaining fingers are opened by solenoids 24, and the robot head lifts and removes the capacitors from the track. The fingers are then all closed and the air motor 18 is reactivated allowing the metal band 22 to drive more capacitors through the track until they hit the stop. This cycle is repeated until the...
