    Abstract: A queue of randomly oriented chips (3) is advanced down a track (4). Each chip in the queue is sequentially and individually elevated into a pneumatic circuit and pressed against a mirrored surface (7) of an upper slide member to which it adheres if the chip was oriented with upwardly disposed solder lands. A jet of compressible fluid insufficient in magnitude to dislodge the chip is injected in a direction toward the queue. If the chip, alternatively, was oriented with the solder lands down, this fluid jet propels the chip about the oval-shaped pneumatic circuit so as to reorient the chip with the lands extending in the desired upward orientation, whereupon the chip is injected into a storage magazine. If the chip was adhered to the mirrored surface, after the first fluid jet, a second fluid jet is introduced to dislodge the correctly oriented chip from the mirrored surface, whereupon a third fluid jet oriented in a direction opposite to that of the first jet and in the direction of the advancing queue, propels the correctly oriented chip along a passageway to the storage magazine. This passageway joins with the oval-shaped inverting passageway which was employed to reorient or flip incorrectly disposedchips as they traversed the reorienting oval.

    Abstract: A queing means transfers surface mount components (17) randomly stored in a detachable hopper (12) into a plurality of parallel lines (16) formed by grooves in a track plate (20). Vibrator means (24) translate the components along the grooves in the downwardly extending track plate toward a shuttle assembly (32). With respect to pairs of such track grooves, the shuttle assembly alternately transports a chip from each groove comprising the pair into a plunger assembly (46). A tube magazine (14) carrying a plurality of carrier tubes (13) to be loaded with components is releasably disposed adjacent the plunger assembly whereby periodic downward movement of plungers simultaneously forces a component from each line of components in the plunger assembly formed by the shuttle mechanism into a respective one of the tubes, and the process is repeated until the tubes are filled with components as desired. Pneumatic means are provided for urging the components backwards from the plunger assembly along the grooves toward and into the hopper. The apparatus is thereby purged in preparation for substitution of a next hopper containing different components and a set of tubes carried by a next tube magazine replacing the one carrying the thus-filled tubes.

    Abstract: A method and apparatus are disclosed for randomly selecting and automatically testing electronic components such as surface mount passive electronic components. A detachable hopper is utilized to contain a plurality of randomly oriented electronic components which are agitated pneumatically and urged by vibration and gravity into a uniform orientation within a groove in an inclined track plate. A seal plate acts in conjunction with the groove within the track plate to form an elongate throat passage which is periodically cleared to prevent clogging by pulsating pneumatic pressure. A component detection circuit is utilized to detect the presence of an electronic component at a predetermined testing postition and a pair of movable conductive probes are then urged into contact with the component to permit testing. In response to a successful test the component under test is then ejected pneumatically back into the detachable hopper. In the discussed embodiment of the present invention, an unsuccessful test will require the unsatisfactory component to be manually removed from the testing position by the operator of the apparatus.
