Rapid detection system and method for comprehensive performance of cylindrical lithium ion battery

Abstract

The invention relates to a rapid detection system and method for the comprehensive performance of a cylindrical lithium ion battery. The detection system comprises an automatic rejection mechanism, a monitoring terminal and any two or more selected from a height detection unit, an anode and cathode end surface appearance defect detection unit, a cylindrical surface appearance defect detection unit, an electrical performance detection unit and a liquid leakage detection unit, the detection units are connected successively, and the detection unit and the automatic rejection mechanism are connected with the monitoring terminal. The detection method comprises that the battery to be detected is driven by a conveyer belt to move to different detection units, the detection unit transmits a detection value to the monitoring terminal, and the monitoring terminal analyzes and processes the detection value to determine whether the battery is qualified; if the battery is qualified, the battery is moved to the next detection unit; and if the battery is not qualified, the automatic rejection mechanism is started, and rejects the unqualified battery to a collection warehouse. Thus, different indexes of the battery can be detected automatically, time and labor are saved, the detection reliability is improved, and the detection units can be combined freely so that use is flexible.

Description

technical field [0001] The invention relates to a battery detection device, in particular to a comprehensive performance rapid detection system and detection method of a cylindrical lithium-ion battery. Background technique [0002] As a new type of energy, lithium-ion batteries are widely used in the fields of digital, electronic equipment, backup energy storage and power energy. The development of power energy, especially pure electric vehicles, has brought greater market demand. Cylindrical lithium-ion batteries, such as 18650 and 26650, are the most widely used lithium-ion batteries, and their comprehensive performance detection methods have always been weak. At present, they are only simply sorted before use, and have not been relatively complete. Therefore, the battery quality cannot be guaranteed, and there are potential safety hazards. Moreover, the current battery testing is generally done manually, which is not only time-consuming and labor-intensive, but also easi...

Problems solved by technology

[0003] The present invention mainly solves the problem that the original battery detection is only simple sorting without a relatively complete system detection, so the battery quality cannot be guaranteed, and there are potential safety hazards. Moreover, the original battery detection is generally done manually, which is not only time-consuming and laborious, but also easily affected. Influenced by human factors, there are technical problems of detection errors; provide a rapid detection system and detection method for the comprehensive performance of cylindrical lithium-ion batteries, which can perform relatively complete detection of various indicators on the battery to ensure the quality of the battery, and each detection is performed by The system is automatically completed, saving time and effort, and avoiding the influence of human factors, effectively reducing errors and improving the reliability of detection
