Abstract

The invention discloses an automatic detection tool for a lithium battery. The automatic detection tool comprises a support, a busbar, a detection assembly and a flow meter, a plurality of liquid passing channels are formed in the support; one ends of the liquid passing channels are in one-to-one butt joint with negative pressure cup assemblies connected with a negative pressure pipeline of the formation equipment; a communicating opening is formed in the support; a confluence channel is arranged in the busbar; a confluence liquid outlet is formed in the end part of the busbar; confluence liquid inlets are formed in the busbar and are in one-to-one correspondence with the communicating ports; a detection liquid inlet of the detection assembly is communicated with the communication port pipeline; the detection liquid outlet is communicated with a confluence liquid inlet pipeline through a flow meter; or the detection liquid outlet of the detection assembly is communicated with the confluence liquid inlet pipeline, and the confluence liquid outlet is communicated with the flow meter; the invention further discloses an application method for testing the single-channel flow and the overall flow of the negative pressure system pipeline of the formation equipment and whether the pipeline is blocked or not. The device has the beneficial effects that gas pressure leakage detection and blockage can be controlled, and the working efficiency is improved.

Description

technical field [0001] The invention relates to the field of tooling, in particular to a lithium battery automatic detection tooling and an application method thereof. Background technique [0002] The formation process is an important step in the production process of prismatic lithium batteries, and the purpose is to activate the battery. During the chemical formation process of the battery, gas will be generated inside, and negative pressure is generally used to extract the gas in the industry. As the gas is discharged, part of the electrolyte in the battery also enters the negative pressure pipeline, and over time, crystals are formed in the pipeline, which blocks the pipeline and affects the quality of the battery. SUMMARY OF THE INVENTION [0003] In order to solve the above problems, the present invention provides an automatic detection tool for lithium batteries and an application method thereof, which can quickly detect whether the gas in the channel is leaked or...
