Abstract

In machines for inserting electrical components into printed circuit cards, each component is removed from a carrier and transported to a work position by means of a feeder. One such feeder comprises a V-shaped channel 10 having a squared groove 11 in the bottom. Pieces of surgical tubing 12 are inserted in holes drilled at an angle in the bottom of the groove as shown in the enlarged detail. The holes are slanted in the direction of travel of the component 14 so that air forced from a chamber in the base of the channel passes through the tubing 12 and drives the component to the work position under the inserting head 15. This arrangement, by reducing air turbulence, results in feeding components smoothly at increased speeds.

In machines for inserting electrical components into printed circuit cards, each component is removed from a carrier and transported to a work position by means of a feeder. One such feeder comprises a V-shaped channel 10 having a squared groove 11 in the bottom. Pieces of surgical tubing 12 are inserted in holes drilled at an angle in the bottom of the groove as shown in the enlarged detail. The holes are slanted in the direction of travel of the component 14 so that air forced from a chamber in the base of the channel passes through the tubing 12 and drives the component to the work position under the inserting head
15. This arrangement, by reducing air turbulence, results in feeding components smoothly at increased speeds.

In order to hold the component until needed, a pivoted stop 16 is located in the channel and is actuated by a solenoid 17. Between the end of the channel and the work position a wire cage 18 provides a guide and a brake for the component. Located beyond the head 15 is a truncated concave cone shaped member 20 for centering the component with respect to the head. A resilient block 21 mounted above the member 20 prevents rebound of the component.
