High-compatibility five-degree-of-freedom new energy automobile charging service robot

Abstract

The invention discloses a high-compatibility five-degree-of-freedom new energy automobile charging service robot which comprises a robot platform and an intelligent charging terminal, the robot platform comprises a three-axis mechanical arm and a butt joint mechanism, the butt joint mechanism is installed at the tail end of the mechanical arm and comprises a butt joint assembly, and the butt joint assembly comprises an error elimination mechanism and a charging plug. The error elimination mechanism comprises a butt joint mounting structure, a flexible joint, a positioning tail end and a positioning pin, the positioning pin is fixed at the positioning tail end, the positioning tail end is mounted at the tail end of the butt joint mechanism through the flexible joint, and the intelligent charging terminal is provided with a standard socket and a positioning groove surface which are electrically connected with a charging port in an automobile. The positioning groove surface comprises a conical groove for guiding the positioning needle to move and a positioning hole which is formed in the center of the conical groove and is matched with the positioning needle in an inserting manner. The identification and positioning process is simple, the charging plug can be automatically guided to be connected under the condition that a large accumulative error is generated, and the accumulative error is collected to be corrected.

Description

technical field [0001] The invention relates to a highly compatible five-degree-of-freedom new energy vehicle charging service robot. Background technique [0002] The existing automated charging piles automatically connect the charging plug with the charging interface of the electric vehicle through a mechanical arm, but the current charging pile automation process mostly uses the charging plug part to actively collect the location information of the charging interface, and uses visual recognition and active laser positioning. However, since the positions and structures of the charging sockets of different models of electric vehicles are different, and most of them are located on the side of the car body, a large amount of information needs to be collected when collecting the position. For example, visual recognition requires complex recognition calculations for images. Laser positioning often requires multiple laser emitting and receiving devices to simultaneously collect ...
