AbstractThe rotary inverter described can be used for shifting the orientation of a part, such as a semiconductor module, 180 degrees. An additional feature of this device is that the rotary inverter can also be used as a sorter in a tightly confined space.
The rotary inverter described can be used for shifting the orientation of a part, such as a semiconductor module, 180 degrees. An additional feature of this device is that the rotary inverter can also be used as a sorter in a tightly confined space.
Referring to the figure, the rotary inverter 10 is shown schematically. The heart of the inverter 10 is spool 12 which rotates in the direction illustrated by arrow 14. Spool 12 contains a slot 16 which has an opening 18. Attached to spool 12 is flange 20.
In operation, a semiconductor module 22, or other object to be inverted or sorted, passes down track 24. Rotary inverter 10 is shown in its home position with the opening 18 in line with track 24. Permanent stop 26 coacts with flange 20 to insure correct alignment.
After module 22 drops into slot 16 in spool 12, clamping cylinder 27 engages the side of the part 22 being sorted to prevent entry of that part into non-selected output tracks as the spool 12 rotates past those tracks. Next, the spool is rotated in direction shown by arrow 14 until it is aligned with one of tracks 28, 30, or 32. Internal logic, not shown controls which output track is desired. Movable stops 34 and 36 are selectively engaged to stop the rotation of spool 14 when struck by flange 20. For example, if track 28 is the desired output track, then stop 34 would be extended and the spool 12 would stop its rotation when the edge 38 of flange 20 engaged stop 34. At this point, the op...
