Pre-positioning platform

The utility model provides a pre-positioning platform which comprises a visual positioning assembly used for placing a target product and a deviation rectifying assembly used for rectifying the position of the target product on a vacuum assembly, the vacuum assembly is arranged on the deviation rectifying assembly, and a first driving unit and a second driving unit are arranged on a base in a spaced and parallel mode. The third driving unit is arranged on the base and is perpendicular to the first driving unit, the deviation rectifying platform is rotatably arranged on the first driving unit, the second driving unit and the third driving unit, and the first driving unit and the second driving unit do not drive the deviation rectifying platform to move at the same time; when the first driving unit drives the vacuum assembly to move in the first horizontal direction, the third driving unit drives the vacuum assembly to move in the third horizontal direction, and the second driving unit does not drive the vacuum
