Automatic charging and replacing system for AGV battery

Abstract

The invention relates to the field of AGVs, and in particular relates to an automatic charging and replacing system for an AGV battery. The system comprises a battery replacing vehicle and a charging cabinet, the charging cabinet is provided with a plurality of charging stations, the battery replacing vehicle is arranged on one side of the charging cabinet and walks in the X direction, and a Y-direction lifting mechanism, a Z-direction moving mechanism and a taking and placing mechanism are arranged on the battery replacing vehicle. The Z-direction moving mechanism is driven by the Y-direction lifting mechanism to ascend and descend, the Z-direction moving mechanism is provided with a Z-direction moving seat, the taking and placing mechanism is arranged on the Z-direction moving seat and comprises a hooking driving device, a hook, a power-on driving device and a power-on pressing contact, the hook is driven by the hooking driving device to ascend and descend in the Y direction, and the power-on pressing contact is driven by the power-on driving device to move in the Z direction. AGV batteries are stored and charged in a centralized mode, the battery replacing vehicle is used for achieving taking, placing and replacing of the batteries, and therefore the AGV does not execute charging operation any more and only executes battery replacing operation with a shorter period, and the working efficiency of the AGV is improved.

Description

technical field [0001] The invention relates to the field of AGV trolleys, in particular to an automatic AGV battery charging and replacing system. Background technique [0002] With the continuous development of industrial automation level and the continuous expansion of modern industrial production scale, AGV trolley has become an indispensable part of the logistics production system. Most of the AGV cars in the prior art use batteries as the energy source, and the AGV cars need to go to the charging station for charging operation when the battery power is insufficient. It needs to be improved. On the other hand, many charging stations need to be configured on the production site, which will take up additional production space. With the development of science and technology, some AGV automatic charging devices have also appeared in the existing technology, but these devices generally have defects such as low positioning accuracy and lack of effective monitoring, and the s...

Problems solved by technology

With the development of science and technology, some AGV automatic charging devices have also appeared in the existing technology, but these devices generally have defects such as low positioning accuracy and lack of effective monitoring, and the scope of application of AGV models needs to be further expanded

In addition, in order to ensure that the AGV battery is firmly fixed, the battery in the prior art will be equipped with a battery locking mechanism, which usually adopts a structure similar to a knife switch. When the battery enters the AGV body or the charging station, the battery is automatically locked, so that the battery cannot be separated. When the battery needs to be taken out, the battery locking mechanism needs to be unlocked first, and then the battery can be taken out, but the AGV automatic charging device in the prior art has not yet been equipped with a structure that can cooperate with the above-mentioned battery locking mechanism
