Guide path for electronic components

1. Apparatus providing a guide path for electronic components having side face surfaces, with a guide channel, in which the components are conducted past a light barrier which detects the components, said light barrier having a transmitter and receiver arranged laterally next to the guide path, such that the light beams are introduced from the side of the guide path into the guide channel, wherein the guide path has guide elements, by means of which the components are guided, at least in the area of the light barrier, obliquely to the direction of the light beams, the guide elements being structured to cause the components to produce shadow surfaces which are higher than the side face surfaces of the components, wherein the guide elements comprise a lower longitudinal rail and a higher longitudinal rail, and wherein a guide web opposite the lower longitudinal rail projects further into the guide channel than a guide web opposite the higher longitudinal rail, such that on both sides of the guide channel the distance interval between each longitudinal rail and each guide web allocated to it is at least essentially the same.

2. The guide path as claimed in claim 1 , wherein the oblique position of the components relative to the main direction of the light beams amounts to 2 to 30°.

3. The guide path as claimed in claim 1 , wherein the lower and higher longitudinal rails are arranged next to one another on the floor of the guide channel, and are of different heights.

4. The guide path as claimed in claim 3 , wherein the longitudinal rails have contact surfaces for the components, which run parallel to the floor of the guide channel, such that the components come into contact only on the edges of the longitudinal rail.

5. Method for guiding electronic components having side face surfaces along a guide path with a guide channel, the method comprising:

introducing light beams from a side of the guide path into the guide channel;

projecting a guide web opposite a lower longitudinal rail further into the guide channel than a guide web opposite a higher longitudinal rail, such that on both sides of the guide channel the distance interval between the longitudinal rail and the guide web allocated to it is at least essentially the same;

conducting the components past a light barrier having a transmitter and receiver arranged laterally next to the guide path, including guiding the components obliquely to the direction of the light beams with guide elements at least in the area of the light barrier;

detecting the conducted components with the transmitter and receiver; and

producing, with the components, shadow surfaces which are higher than the side face surfaces of the components.
