An AGV automatic charging system and method integrating docking success physical quantity feedback

Abstract

The invention discloses and provides an AGV automatic charging system and method integrating docking success physical quantity feedback. The positioning and pose errors of the AGV can be self-adapted,and the attaching conduction between electric brushes can be well completed; the AGV automatic charging task can be reliably and safely completed; a protection door ensures the safety, reliability and service life of an electric brush and prolongs the service life of the system. The technical scheme adopted by the charging system is as follows: the charging system comprises a charging pile and anAGV cart. A charging docking device is arranged in the side face of the AGV cart. The charging docking device comprises an electric cylinder, an electric cylinder fixing seat, a connecting seat connected with an output shaft of the electric cylinder, and an electric brush module arranged in front of the connecting seat; the output shaft is perpendicular to the side face, a through hole matched with the charging docking device is formed in the side face of the AGV cart, the electric brush module comprises the electric brush and an electric brush isolation mounting plate; the rear portion of the electric brush isolation mounting plate is connected with the connecting seat in a hinged mode, and a charging brush head module matched with the electric brush module is arranged on the charging pile. The system and method can be applied to the field of AGV carts.

Description

technical field [0001] The invention relates to an AGV automatic charging system and method that integrates physical quantity feedback of docking success. Background technique [0002] With the advocacy and implementation of Industry 4.0, the degree of automation and intelligence in the manufacturing and logistics industries continues to increase. AGV (automated guided vehicle) has developed rapidly because of its intelligent and flexible material transmission functions. At present The application of AGV is not limited to the traditional unmanned storage environment, but its application has been extended to some transportation environments with harsh working environment and simple labor but high intensity. One of the stable and continuous operations of the AGV depends on the reliable supplement and stable output of power energy. The accurate and timely charging and charging management of the AGV is particularly important. This requirement requires the AGV to have a reliable ...

Problems solved by technology

[0003] The existing AGV automatic charging scheme does not have feedback on the successful docking between the brushes. Most of them are based on an open-loop control with accurate AGV debugging and positioning as a priori condition, which cannot ensure the correct fit and conduction between the brushes. The risk of arcing and short circuit; the existing technology does not disclose or disclose the posture adjustment of the AGV when it stops in front of the charging pile; the self-adaptiveness of the successful docking of the brushes is poor, and the existing AGV automatic charging brushes are fixed in only one active dimension On the components, when the posture of the car body is wrong, there may be only wire contact between the brushes, and an arc will be generated after the charging circuit is turned on, which will ablate the brushes and cause greater harm; the brushes are not protected, and the application number is CN Patent No. 108116257 A discloses a movable brush exposed on the charging pile, which poses certain safety problems to equipment and people; patent application number CN 108116266 A discloses a buried charging pile brush, and the brush is exposed to the charging pile. People and electrodes themselves are detrimental
