Abstract

An apparatus for arranging integrated circuit receiving tubes, the apparatus including a reverse mechanism, a detection element and a discharge mechanism. In use, the reverse mechanism receives a tube and the detection element determines an orientation of the received tube. The reverse mechanism moves to allow the discharge mechanism to receive the tube from itself. If the orientation of the received tube differs from a desired orientation, the movement of the reverse mechanism changes the orientation of the tube before allowing the discharge mechanism to receive the tube. Otherwise, the orientation of the tube is maintained notwithstanding the movement of the reverse mechanism, and is subsequently received by the discharge mechanism. This helps to automatically ensure that all the tubes are received by the discharge mechanism in the same orientation.

First claim

The invention claimed is:

1. An apparatus for arranging tubes configured to receive integrated circuit packages, the apparatus comprising:
a reverse mechanism configured to receive a tube;
a detection element configured to determine an orientation of the tube received by the reverse mechanism; and
a discharge mechanism, the reverse mechanism being movable selectively between a first position which prevents the discharge mechanism from receiving the tube from the reverse mechanism and a second position which allows the discharge mechanism to receive the tube;
wherein the movement of the reverse mechanism between the first position and the second position is dependent on the determined orientation of the tube,
wherein the reverse mechanism is rotatable, and
wherein rotation of the reverse mechanism in one direction from the first position to the second position maintains the orientation of the tube, and rotation of the reverse mechanism in the other direction from the first position to the second position changes the orientation of the tube.

2. An apparatus according to claim 1 , further comprising a separation mechanism configured to ensure the receiving of a single tube by the reverse mechanism.

3. An apparatus according to claim 2 , wherein the separation mechanism comprises at least one groove sized to receive a single tube.

4. An apparatus according to claim 3 , further comprising an urging mechanism configured such that when a plurality of tubes are received by the at least one groove, the urging mechanism repeatedly urges the plurality of tubes away from the at least one groove until a single tube is received by the at least one groove.

5. An apparatus according to claim 3 , further comprising a tube present detection device configured to detect if a tube has been received by the at least one groove.

6. An apparatus according to claim 5 , wherein the detection element is configured to determine the orientation of the tube received by the at least one groove after the tube present detection device has detected that a tube has been received.

7. An apparatus according to claim 6 , wherein the apparatus further comprises a reject mechanism configured to urge the tube out of the at least one groove if the detection element is unable to detect the orientation of the tube after the tube present detection device has detected that a tube has been received.

8. An apparatus according to claim 2 , wherein the separation mechanism and the reverse mechanism are separate and wherein the separation mechanism is movable to allow the reverse mechanism to receive the single tube from the separation mechanism.

9. An apparatus according to claim 2 , wherein the separation mechanism is comprised in the reverse mechanism.

10. An apparatus according to claim 1 , wherein the reverse mechanism and the discharge mechanism comprise respective grooves for receiving the tube, and wherein the grooves of the reverse and discharge mechanism are misaligned when the reverse mechanism is in the first position and are aligned when the reverse mechanism is in the second position.

11. An apparatus according to claim 1 , wherein the reverse mechanism is configured to rotate 45 degrees in the clockwise direction to maintain the orientation of the tube and 135 degrees in the anti-clockwise direction to change the orientation of the tube.

12. An apparatus according to claim 1 , further comprising tube grooves configured to facilitate movement of the tube from the reverse mechanism to the discharge mechanism.

13. An apparatus according to claim 1 , further comprising support structures with V-shaped openings to facilitate the apparatus to receive the tubes.

14. A method of arranging tubes configured to receive integrated circuit packages, the method comprising:
receiving a tube with a reverse mechanism;
determining an orientation of the received tube;
moving the reverse mechanism selectively between a first position which prevents receiving of the tube from the reverse mechanism and a second position which allows receiving of the tube from the reverse mechanism;
wherein the movement of the reverse mechanism between the first position and the second position is dependent on the determined orientation of the tube,
wherein the reverse mechanism is rotatable, and
wherein rotation of the reverse mechanism in one direction from the first position to the second position maintains the orientation of the tube, and rotation of the reverse mechanism in the other direction from the first position to the second position changes the orientation of the tube.
