Abstract

This vibrating bowl provides desired alignment of relatively small and light parts, typically L-shaped straps used in microrelectric diode assembly techniques as disclosed, for example in the IBM Technical Disclosure Bulletin, Vol. 12, No. 9, February 1970, page 1524. The apparatus consists of a vibrating bowl having spiral grooved ramps. Portions of the vibrating bowl which achieve the specific functions are shown. In drawing A: two tracks are simultaneously fed, while excess of parts are rejected. In drawing B: a first selection is made, L-shaped straps are tilted 45 degrees and jammed parts are eliminated. In drawing C: a new tilt of 45 degrees is performed, only correctly oriented straps are kept. In drawing D: a new 45 degrees tilt is followed by a 30 degrees tilt.

Vibratory Feeder

This vibrating bowl provides desired alignment of relatively small and light parts, typically L-shaped straps used in microrelectric diode assembly techniques as disclosed, for example in the IBM Technical Disclosure Bulletin, Vol. 12, No. 9, February 1970, page 1524. The apparatus consists of a vibrating bowl having spiral grooved ramps. Portions of the vibrating bowl which achieve the specific functions are shown. In drawing A: two tracks are simultaneously fed, while excess of parts are rejected. In drawing B: a first selection is made, L-shaped straps are tilted 45 degrees and jammed parts are eliminated. In drawing C: a new tilt of 45 degrees is performed, only correctly oriented straps are kept. In drawing D: a new 45 degrees tilt is followed by a 30 degrees tilt. In drawing E: correctly aligned straps are placed on the feeding track for subsequent processing.

This vibrating bowl is characterized in that two feeding tracks may be implemented without an entering angle: this allows the bowl to be electroformed.
