ABSTRACT:
A chip component handling and loading system for orienting and transporting a plurality of generally rectangular chip components includes a storage and feed location which, by means of vibratory action, randomly shakes out the chip components into or onto a series of twenty-five substantially parallel, generally rectangular channels. These channels are sized and arranged to receive the chip components in only one proper orientation. Any chip component which is not properly oriented either will not fit in the channel, or will fit in the channel as to its width and not height and downstream from the entry into the channels is a brush-back station where any improperly oriented chip component is either brushed away from the top surface of the channels or is brushed into a proper orientation. The channel dimensions represent the most likely orientation for the randomly vibrated chip components though not the necessary orientation for electrical testing of the components and loading these components into the clear plastic strip which will ultimately be used by the circuit board manufacturer. Consequently, a roll-over insert block is provided so as to transform the orientation of the chip components as initially loaded into the channels into a different orientation which corresponds to that required for electrical testing and component loading.
