Abstract
Abstract A pick and place machine having an electronic component feed device is described. The feed device feeds electronic components to various pick up locations with such high positional accuracy that alignment jaws on the pick up head are not necessary. Elevated tracks run parallel to a printed circuit board conveyor belt. These elevated tracks support an arm which in turn supports the electronic component pick up head. The feed device is positioned under the elevated tracks so that an operator can replenish the supply of electronic components in the feed device without reaching over the tract.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
162 words
An electronic component supply for supplying electronic components to a pick-up location, comprising: a mostly inclined member having at least one channel forming groove extending from a higher to a lower position along said member, said channel at least one sidewall, wherein the channel is adapted to guide the electronic components in the channel from a higher end of the channel to the pick-up location at a lower end of the channel, the lower end of said channel at the pick-up location being horizontally disposed; a stop at the lower end of the channel for preventing further movement of the electronic components past the stop; and vibrating means for vibrating said inclined member back and forth along a line, said line being disposed at an acute angle relative to a longitudinal direction of the lower end of the channel at the pick-up location, so that the vibrations simultaneously urge the components against the stop and against the one sidewall of the channel.
Claim 2
Dependent Claim
162 words
An electronic component supply for supplying electronic components to a pick-up location, comprising: a mostly inclined member having at least one channel forming groove extending from a higher to a lower position along said member, said channel at least one sidewall, wherein the channel is adapted to guide the electronic components in the channel from a higher end of the channel to the pick-up location at a lower end of the channel, the lower end of said channel at the pick-up location being horizontally disposed; a stop at the lower end of the channel for preventing further movement of the electronic components past the stop; and vibrating means for vibrating said inclined member back and forth along a line, said line being disposed at an acute angle relative to a longitudinal direction of the lower end of the channel at the pick-up location, so that the vibrations simultaneously urge the components against the stop and against the one sidewall of the channel.
Claim 3
Dependent Claim
30 words
The electronic component supply of claim 1, wherein said acute angle is approximately 10° from the longitudinal direction of the lower end of the channel at the pick up location.
