Abstract

A guide rail for electronic components, especially for use in robots for electronic components. The guide rail comprises a vertical or inclined guide duct that is provided with a curved, undulating guide track along at least one section thereof in order to decelerate components as the components slide within the guide track.

Claims (15)

1. A guide path for electronic components, in particular for use in handling robots for electronic components, with a guide channel which is arranged vertically or obliquely and is configured in such a way as to allow the components to slide along the guide channel owing to their gravitational force, the guide channel having at least one base-side guide surface, lateral guide surfaces and at least one cover-side guide surface, wherein the guide channel has an undulating guide track at least over a portion of its length, and wherein friction between the guide track and the component is increased and speed of the components is reduced so that damage to the components is reduced when the components strike stopping means.

2. The guide path as claimed in claim 1 , wherein the guide track undulates in a plane lying perpendicularly to the base-side or cover-side guide surfaces.

3. The guide path as claimed in either claim 1 , wherein the undulating course of the guide track is formed by base-side and cover-side guide rails on which the base-side and cover-side guide surfaces are provided, these guide surfaces being at varying distances from the base of the guide channel along the guide channel.

4. The guide path as claimed in claim 1 , wherein the guide track undulates in a plane lying parallel to the base-side or cover-side guide surfaces.

5. The guide path as claimed in claim 1 , wherein the undulating course of the guide track is formed by arched track portions.

6. The guide path as claimed in claim 1 , wherein the undulating course of the guide track is formed by rectilinear, parallel track portions which are offset in the lateral and/or depth direction and are joined together by obliquely arranged track portions.

7. An electronic component guide path comprising:

a guide channel comprising at least one base-side guide surface, lateral guide surfaces and at least one cover-side guide surface, the guide channel being configured to allow electronic components to slide along the guide surfaces under the force of gravity; and

a stopping device disposed in communication with the guide channel, the stopping device being configured to stop the electronic components from further sliding upon striking the stopping device;

the guide channel including an undulating guide track that applies friction to the sliding electronic components thereby reducing the speed of sliding components striking the stopping device to reduce the chance of damaging the electronic components when the electronic components strike the stopping device.

8. A method of guiding electronic components comprising:

sliding the electronic components under force of gravity along a guide channel comprising at least one base-side guide surface, lateral guide surface, and at least one cover-side guide surface;

sliding the electronic components through an undulating guide track disposed along at least a part of the length of the guide channel;

applying, with the undulating guide track, friction to the sliding electronic components while imposing a uniform delay on each said sliding component; and

after applying friction, directing the sliding components to strike a stopper while using said applied friction to reduce the speed of the sliding components striking the stopper thereby reducing the chance of damaging the electronic components when the electronic components strike the stopping device.
