Graphene battery conductivity detector

Abstract

The graphene battery conductivity detector comprises a machine body shell, a working cavity is formed in the machine body shell, a first driving shaft is installed in the working cavity, four first connecting blocks which are annularly arranged are fixedly arranged on the first driving shaft, and first insulating blocks are fixedly arranged at the tail ends of the first connecting blocks; a detection cavity with an opening away from the first connecting block is formed in the first insulating block; a first electric push rod is mounted in the side wall of the detection cavity; a conductive contact can be flexibly connected with a battery contact under the driving of a second electric push rod and the action of a fourth spring, so that a circuit is conducted, the battery contact is protected, the contact is prevented from being damaged, a magnetic field is generated after an electromagnet is electrified to push a permanent magnet to move upwards, and the safety of the battery is improved. The distance detector can detect the moving distance of the permanent magnet, the conductivity of the battery is judged by detecting the rising distance of the permanent magnet, and the higher the rising distance of the permanent magnet is, the better the conductivity is.

Description

technical field [0001] The invention relates to the technical field of conductivity detection, in particular to a graphene battery conductivity detector. Background technique [0002] Graphene battery is a kind of battery, which is developed by utilizing the characteristics of rapid and large-scale shuttle movement of lithium ions between the graphene surface and electrodes. The advantages are also extremely prominent. In order to ensure the quality of the battery, it is necessary to conduct a conductivity test on the completed battery. [0003] In the prior art, the detection is generally carried out manually, and the battery is generally detected by manually picking up the battery during the detection. The workers are easy to touch the positive and negative electrodes of the battery, which may cause electric shock, and continuous testing cannot be performed, so that it may not be possible to accurately match the battery. The electrodes are in contact, which can lead to de...
