The utility model relates to the technical field of material stacking, in particular to a double-station linear stacking robot. The lateral part or top of the frame body is provided with a traversing mechanism, a grab frame is arranged below a cross frame in the traversing mechanism, a motion control mechanism for controlling the grab frame is arranged in the cross frame, a conveying mechanism is arranged below the cross frame, and a lifting mechanism is arranged at the lateral part of the conveying mechanism. Materials can be directly stacked on the lifting plate through the grab frame, and the lifting mechanism designed in double position further improves the stacking efficiency. After the materials are stacked, the forklift or crane can be used to directly unload the materials from the lifting plate, and there is no need to push the materials out with a tray, which also avoids the collision between the materials and the grasping device when the original forklift is used to carry them, improves the stacking efficiency of the materials, ensures the uniformity of the materials stacking, and reduces the labor cost and manufacturing cost.
