Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of logistics transportation, especially a conveying device for exchanging empty and full trays and workpieces. BACKGROUND

[0002] In a welding workshop, the bottom plate subassembly station and the midsole synthesis station are far apart, so they need to be transported by a docking trolley. The midsole station has double-layer slides, one end of the slide is on a logistics channel and needs to be connected with the docking trolley, and the other end of the slide is on the side of an operator and needs to be operated by the operator. The slide is divided into upper and lower slides, the upper slide is used to slide the workpiece on the tray outward, and the lower slide is used to slide the empty tray inward.

[0003] There is a lifting device inside the slide. When the lower tray slides into the slide of the lifting device from the lower slide, the robot puts the workpiece on the jig, and the operator uses a lifting tool to lift the workpiece from the jig and put it into the empty tray of the lifting device. Then press the lifting button, and the lifting device rises and aligns with the upper slide. The operator then pushes the tray downward, and then presses the lowering button. The lifting device lowers and docks with the lower slide, which is one cycle of operation.
