Reverse connection prevention detecting device for lithium ion battery positive and negative electrode lugs

Abstract

The invention discloses a reverse connection prevention detecting device for lithium ion battery positive and negative electrode lugs. The reverse connection prevention detecting device comprises a base and a limiting assembly, a lifting driving assembly and a testing assembly which are arranged on the base; and the limiting assembly is used for limiting a core, and the testing assembly is arranged on the lifting driving assembly and comprises a fixing plate, detection pins, an indicator light and a buzzer, wherein the detection pin, the indicator light and the buzzer are arranged on the fixing plate, and the fixing plate is arranged on the lifting driving assembly. By arranging the detection pins, the indicator light and the buzzer, the problem that it is difficult to find that the core is reversely placed to be encapsulated can be effectively solved, and the voltage internal resistance of the core can be tested and uploaded to a computer database for testing battery voltage drop while reverse connection testing on the core is conducted; and accordingly, the battery testing effectiveness is improved, and safety accidents are effectively prevented.

Description

technical field [0001] The invention relates to the field of lithium batteries, in particular to an anti-reverse detection device for positive and negative tabs of a lithium ion battery. Background technique [0002] A lithium battery is a primary battery that uses lithium metal or lithium alloy as the negative electrode material and uses a non-aqueous electrolyte solution. It is different from a rechargeable battery. Lithium-ion batteries are different from lithium-ion polymer batteries. The inventor of the lithium battery is Edison. Due to the very active chemical properties of lithium metal, the processing, storage and use of lithium metal have very high environmental requirements. Therefore, lithium batteries have not been used for a long time. With the development of microelectronics technology at the end of the 20th century, miniaturized equipment is increasing day by day, which puts forward high requirements for power supply. Lithium batteries have entered a large-...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to overcome the deficiencies in the prior art, and provide a lithium-ion battery positive and negative ear anti-reverse detection device, by setting detection pins, indicator lights and buzzers, it can effectively solve the It is difficult to find the problem that the core is reversed and packaged. At the same time as the battery is reversed, the internal resistance of the battery voltage can also be tested and uploaded to the computer database to test the battery voltage drop, which improves the effectiveness of battery testing and effectively prevents safety accidents.
