▎ 摘　　要

NOVELTY - The detector has a working cavity whose bottom wall is provided with a moving component capable of driving a rotating block to move. The rotating block is formed with a sliding groove with an opening towards a left. The sliding groove is fixed with a first sliding block in sliding connection. A feeding component is fixed in the sliding groove. A second electric push rod is provided on a top wall of the working cavity corresponding to a position of a first insulating block above. An output end of the second electric pushing rod is fixedly provided with second insulating blocks. A code spraying cavity is connected with a code spraying component for automatically marking a detection date of a battery spraying code. USE - Graphene battery conductivity detector used in graphene military engineering field, and used in electric vehicles, hybrid electric vehicles and fuel cells. ADVANTAGE - The conductive contact can be flexibly connected with the battery contact under the driving of the second electric push rod and under the action of the fourth spring so as to conduct the circuit, protect battery contact, prevent the contact from being damaged, and the electromagnetic iron generates magnetic field to push the permanent magnet to move upwards after electrified. The first sliding block can be pressed on the first insulating block of the right under action of second spring and the fourth electric rod, it has function of abutting the detecting cavity to prevent the battery from falling, and second push plate can push the battery placed in the transfer cavity into the detection cavity of right side under the right side of the first connecting block, playing the role of automatic feeding, reducing the labor intensity of the worker. DESCRIPTION OF DRAWING(S) - The drawing shows a structural diagram of Graphene battery conductivity detector.
