Lithium battery incoming material detection line

Abstract

The invention discloses a lithium battery incoming material detection line, which comprises a conveying device, a scanning device, an encoding tray, a code scanner, a formation device, a screening device and a control device, wherein the conveying device is used for conveying a lithium battery; the scanning device is arranged above the conveying device and used for scanning a bar code of the lithium battery; the encoding tray is used for accommodating the scanned lithium battery; the code scanner is used for scanning a bar code of the encoding tray; the formation device is used for testing voltage capacity and internal resistance of the lithium battery in the encoding tray; the screening device is used for testing and screening the standing lithium battery detected by the formation device; and the control device is connected with the conveying device, the scanning device, the code scanner, the formation device and the screening device. The lithium battery incoming material detection line is high in incoming material detection efficiency, and can ensure quality consistency and quality reliability of the lithium battery.

Description

technical field [0001] The invention relates to the technical field of lithium batteries, in particular to a lithium battery incoming material detection line. Background technique [0002] The lithium battery cells used in the production of lithium battery power supply, that is, lithium battery PACK, need to be inspected after they are offline to determine the value and consistency of the voltage capacity and internal resistance of the battery cells, so as to carry out the PACK of lithium battery packs. The incoming battery cells are usually cylindrical, and the data to be tested mainly include voltage capacity, internal resistance, voltage, etc. The existing testing equipment for incoming lithium battery cells is a capacity separation cabinet or a formation cabinet. During the inspection and test, workers need to manually install lithium battery cells one by one into the equipment. Each lithium battery needs to be supported by upper and lower thimbles. About a hundred. Af...

Problems solved by technology

[0003] Due to the inevitable deviation and the need to take into account the two parameters, it takes a lot of time to manually sort lithium batteries after testing, and there is a great chance of misoperation, which will affect the quality consistency of lithium batteries.

At the same time, because the system performance of the lithium battery that has just been rolled off the assembly line has not stabilized, the measured data is not the data after the lithium battery has been static. There are deviations in the voltage capacity and internal resistance of the lithium battery, which further affects the quality consistency of the lithium battery.

[0004] In addition, since the performance parameters of all lithium batteries are not stored, after the lithium battery is transferred to the user, the quality problem of the lithium battery is difficult to trace and identify, which will affect the quality and reliability of the lithium battery
