Conveyor apparatus and method for transporting leadframe |
摘要 |
A conveyor apparatus for a leadframe includes a track defining a longitudinally extending passage through which the leadframe travels. A magnetic clamping system and a plurality of first guide magnets are provided on the track. A gripping device is provided for securing to the leadframe. At least one clamping magnet and a plurality of second guide magnets are secured to the gripping device. The first and second guide magnets cooperate to move the gripping device in a first direction along the length of the passage. The magnetic clamping system and the at least one clamping magnet cooperate to selectively move the gripping device in a second direction perpendicular to the first direction between a first condition spaced from the track to a second condition magnetically fixed to the track. |

1. A conveyor apparatus for a leadframe comprising:
a track defining a longitudinally extending passage through which the leadframe travels, a magnetic clamping system and a plurality of first guide magnets being provided on the track; and a gripping device to secure to the leadframe, at least one clamping magnet and a plurality of second guide magnets being secured to the gripping device; the first and second guide magnets cooperating to move the gripping device in a first direction along the length of the passage while in a first condition that is spaced from the track, the magnetic clamping system and the at least one clamping magnet cooperating to selectively move the gripping device in a second direction that is substantially perpendicular to the first direction between the first condition spaced from the track to a second condition magnetically fixed to the track. |
