Transfer mechanism and transfer device

A transfer mechanism comprising:

• a rail;
• a first table and a second table, the first table and the second table being movably mounted on the rail;
• a first arm and a second arm, the first arm and the second arm being pivotably supported by the first table and the second table, respectively;
• a first drive mechanism and a second drive mechanism being configured to independently move the first table and the second table along the rail, respectively,
• wherein the first arm and the second arm are pivotally connected to each other at a position between a tip side and a base side thereof,
• wherein tip side portions of the first arm and the second arm than a connected portion of the first arm and the second arm serve as fingers for holding a workpiece,
• wherein a relative movement of the first table and the second table in opposite direction by the first drive mechanism and the second drive mechanism causes the first arm and the second arm to perform a clamp/unclamp operation, and
• wherein a coordinated movement of the first table and the second table in the same direction causes the first arm and the second arm to perform an advance/return operation.
