AGV (automatic guided vehicle) automatic charging device, system and method

Abstract

The invention discloses an AGV automatic charging device, system and method. The automatic charging method includes: a central processing module starts a visual module after receiving a charging instruction; the visual module shoots an image of a to-be-charged AGV vehicle; the central processing module processes the image of the AGV vehicle and positions a charging electrode of the AGV vehicle; amechanical motion module controls butt joint of a charging contact and the charging electrode of the AGV vehicle according to position information of the charging electrode of the AGV vehicle under the control of the central processing module; a charging module detects a charging state of the AGV vehicle and correspondingly charges the AGV vehicle; after the charging module detects that charging of the AGV vehicle is finished, a charging circuit is closed; the mechanical motion module controls the charging contact to separate from the charging electrode of the AGV vehicle and controls the charging contact to return to an initial position. The AGV automatic charging device, system and method have advantages that self adaptability of the AGV automatic charging device is improved, and the requirement on AGV vehicle parking accuracy is lowered.

Description

technical field [0001] The invention relates to the technical field of AGV charging, in particular to an AGV automatic charging device, system and method. Background technique [0002] Today, with the rapid development of smart manufacturing, AGVs that can efficiently and unmanned transport logistics have become an indispensable part of factories, greatly improving the logistics efficiency of modern manufacturing factories and reducing labor costs. At present, basically all AGV cars use battery power to provide power for operation. When the AGV car is running to the state of running out of power, the scheduling algorithm will run the AGV car to a specific charging position for charging. Therefore, the factory will also equip the AGV car with special charging equipment to meet the charging needs of the AGV car, so that the AGV car can continue to run stably. The charging contacts of the general charging equipment and the charging electrodes of the AGV car correspond to each ...

AI Technical Summary

Problems solved by technology

[0004] (1) One type of charging equipment generally can only correspond to the corresponding AGV car, and the adaptability is not high

[0005] (2) The charging contacts of the charging equipment cannot be positioned automatically, and the positioning accuracy requirements for the AGV car to stop when charging are relatively high

[0006] (3) If there are multiple types of charging equipment, it will increase the difficulty of the scheduling algorithm and reduce the space utilization rate
