Method and system for aligning shelves with robots

Abstract

The invention discloses a robot and goods shelf alignment method and system. The robot and goods shelf alignment method comprises the following steps that a robot gets close to a goods shelf accordingto an advancing path, and then a guide channel arranged at the bottom of the goods shelf is used for correcting the advancing path to enable the robot to dive into the goods shelf, wherein the guidechannel is surrounded by guide rails which are arranged on the two sides of the advancing path; and a camera is used for identifying an identification label arranged at the bottom of the goods shelf so as to ensure that the position of a jacking rod of the robot and the position of a traction hole of the goods shelf correspond to each other, and then the jacking rod rises and extends into the traction hole. When the jacking rod of the robot corresponds to the position of the traction hole of the goods shelf, the camera is located under the identification label. According to the robot and goodsshelf alignment method and system, alignment deviation is corrected while the robot moves, and the time consumed by accurate alignment of the jacking rod and the traction hole is shortened, so that the alignment efficiency of the jacking rod and the traction hole is improved.

Description

technical field [0001] The invention relates to the technical field of docking between a robot and a shelf, in particular to a method and a system for aligning a shelf with a robot. Background technique [0002] When the latent robot is dragging and hanging some carriers such as shelves, it needs to use jacking rods to fix and drag movable shelves and other carriers. One or more sets of ejector rods are required on the robot chassis; when the robot is automatically loading and unloading the shelves, the jacking The rod needs to be inserted into the traction hole at the bottom of the shelf to realize the traction of the shelf. However, due to the allowable error of the butt joint between the traction hole and the jacking rod, it is very difficult to align the jacking rod with the traction hole, resulting in the alignment between the robot and the shelf. The alignment process is too long, which greatly reduces the efficiency of intelligent warehousing and seriously affects the...

However, due to the allowable error of the butt joint between the traction hole and the jacking rod, it is very difficult to align the jacking rod with the traction hole, resulting in the alignment between the robot and the shelf. The alignment process is too long, which greatly reduces the efficiency of intelligent warehousing and seriously affects the development of intelligent warehousing. Therefore, it is urgent for those skilled in the art to provide a method to improve the accuracy of the alignment between the robot and the shelf, so as to shorten the docking time and improve Efficiency and throughput in smart warehousing
