Automatic positioning correction mechanism

The invention discloses an automatic positioning correction mechanism. The automatic positioning correction mechanism is mounted on a working platform; a first working hand is used for moving a first workpiece; a second working hand is used for moving a second workpiece; and the automatic positioning correction mechanism comprises a first measurement positioning module for performing the size measurement and the positioning for the first workpiece in an X direction, a second measurement positioning module for performing the size measurement and the positioning for the first workpiece in a Y direction, a third measurement positioning module for performing the size measurement and the positioning for the second workpiece in the X direction, and a fourth measurement positioning module for performing the size measurement and the positioning for the second workpiece in the Y direction. When the automatic positioning correction mechanism is used for automatically aligning the workpieces, the positioning process is unrelated to materials, colors and the like of the workpieces, and the positioning and the alignment are performed in dependence of shapes of the workpieces. The size qualification of the workpieces can be synchronously detected in the automatic alignment process of the workpieces, so that the equipment cost and the labor operation cost are reduced.
