Positioning transmission device

The utility model provides a positioning transmission device comprising a frame, a vertical lifting platform and a two-stage horizontal sliding platform, wherein the frame is provided with a shifting cavity; and the vertical lifting platform comprises a guide piece, a vertical driving mechanism, a push rod and an upper lifting plate and a lower lifting plate which are parallel to one another; the two-stage horizontal sliding platform comprises a sliding plate, a horizontal driving mechanism, a push block and a bearing plate for loading and unloading a substrate bearing box, the lower lifting plate does vertical movement along the guide piece under the driving of the vertical driving mechanism and drives the bearing plate to make synchronous movement through a push rod, and the horizontal driving mechanism drives the push block to drive a sliding plate to make horizontal sliding through the pushing block; and the bearing plate can horizontally slide on the sliding plate under a horizontal direction force to extend to the position of loading and unloading the bearing box. The positioning transmission device can simultaneously realize the height adjustment on the vertical direction and two-stage sliding adjustment on the horizontal direction, has the advantages of less occupied space, simple alignment, convenient operation and labor saving, and can improve transmission quality and accuracy and reduce transmission cost.
