Automatic grading control apparatus of power lithium battery

Abstract

The invention relates to an automatic grading control apparatus of a power lithium battery. The automatic grading control apparatus comprises a battery loading unit, an automatic conveying unit, a bar code scanner, a battery OCV detection unit, a battery sorting unit, a battery storage unit and a central controller, wherein the central controller comprises a recognition module, a battery information storage module and a PLC control module, the recognition module and the battery information storage module form a signal connection, the battery information storage module and the PLC control module form a signal connection, the battery loading unit, the automatic conveying unit and the battery sorting unit are controlled by the PLC control module, and a power output terminal of the automatic conveying unit is connected with a conveying belt. The automatic grading control apparatus has the following beneficial effects that: grading is accurate, the system is stable, and human intervention is reduced; the apparatus can be used separately, and can further be integrated in a lithium battery production line; and the space is saved, on-site monitoring and data sharing can be achieved, special duty is not required, and system maintenance is convenient.

Description

technical field [0001] The invention relates to an automatic gear-grading control device for power lithium batteries. Background technique [0002] In recent years, with the improvement of science and technology and the popularization of new energy technology, power lithium battery is used as a module combination to provide power for large electric equipment. The internal resistance of lithium batteries has become an important factor affecting the life of large lithium battery modules. In order to improve the life of lithium battery modules, it is necessary to carry out strict internal resistance, voltage testing and quality classification for single lithium batteries. Most of the existing power lithium battery sorting machines are manual sorting, the sorting efficiency is low, the sorting cost is high, and there are too many human factors in the sorting process, resulting in poor sorting quality. Contents of the invention [0003] The present invention aims at the probl...
