Description

Technical Field

[0001] This utility model relates to the technical field of AGV (Automated Guided Vehicle) charging, and in particular to an AGV charging device and AGV system. Background Technology

[0002] In scenarios such as automated logistics sorting, intelligent manufacturing production lines, and warehouse cargo transfer, AGVs (Automated Guided Vehicles) serve as core automated handling equipment. With their characteristics of not requiring manual driving and being able to drive autonomously according to preset paths or real-time scheduling, they significantly improve cargo handling efficiency and operational accuracy, reduce labor costs and human error, and have become a key component of modern automated production and logistics systems.

[0003] Currently, most charging devices for AGVs are fixed in place, and their positions cannot be flexibly adjusted after installation, making it difficult to move synchronously with the AGV along a preset path (such as a track). In actual operation scenarios, when the AGV needs to replenish its power while traveling, or needs to temporarily recharge at non-fixed locations due to operational needs, the fixed charging devices cannot dynamically adapt to the real-time position of the AGV, and cannot accurately match the charging interface position of the AGV. This not only easily leads to charging interruptions, but also fails to achieve the efficient "charging while working" replenishment mode. In this situation, the AGV needs to frequently interrupt its current transport task, travel to the fixed charging area to complete charging, and then return to the work path, increasing the frequency of work interruptions and affecting the continuity of the overall work process and the efficiency of automated transport.

[0004] Currently, no effective solution has been proposed to address the problems of AGV charging devices being difficult to synchronize, causing work interruptions and affecting efficiency in related technologies. Utility Model Content

[0124] The method of using this utility model is as follows: (a) Charging operation The first driving element 134 is activated, causing the moving element 133 to rotate vertically, which in turn causes the second sliding element 131 to move along the length of the first sliding element 112. The second sliding element 131 then causes the housing element 121 to move accordingly until it reaches the bottom of the AGV vehicle, at which point the first driving element 134 stops operating. The second drive element 146 is activated, causing the first rotating element 147 to rotate circumferentially along the second rotating element 149. The first rotating element 147 then drives the lifting element 142 to move upward along the axis of the first guide element 141. The lifting element 142 drives the first plug-in element 143 and the first charging element 144 to move accordingly, so that the first plug-in element 143 protrudes out of the first through slot element 122 and plugs into the AGV, and the first charging element 144 protrudes out of the second through slot element 123 and is electrically connected to the AGV, thereby charging the AGV.

[0126] (ii) End charging The second drive element 146 is activated, causing the first rotating element 147 to rotate circumferentially along the second rotating element 149. The first rotating element 147 then drives the lifting element 142 to move downward along the axis of the first guide element 141. The lifting element 142 drives the first plug-in element 143 and the first charging element 144 to move accordingly, so that the first plug-in element 143 moves into the first through slot element 122 and separates from the AGV, and the first charging element 144 moves into the second through slot element 123 and separates from the AGV.

[0127] The advantages of this invention are that the cooperation between the base unit, the housing unit, and the moving unit provides a guiding effect for the housing unit. The sliding structure of the base unit provides a motion trajectory for the moving unit, ensuring that the moving unit drives the housing unit to move smoothly back and forth along the length direction without jamming or deviation. This allows the AGV charging device to follow the AGV and avoids charging interruption due to synchronization deviation. The charging drive unit provides a charging docking effect for the AGV, and the device can be plugged in or separated from the AGV through lifting motion, ensuring the stability of the charging connection.

The second sliding element 131 then causes the housing element 121 to move accordingly until it reaches the bottom of the trolley element 301, at which point the first driving element 134 stops operating. The second drive element 146 is activated, causing the first rotating element 147 to rotate circumferentially along the second rotating element 149.
