On-line repairing work processing method of cell

Abstract

The invention relates to an on-line repairing work processing method of a cell. The method comprises: information of a to-be-repaired cell is retrieved, an original bar code is printed for the to-be-repaired cell and is scanned into a database, and a correspondence relation with the to-be-repaired cell information is established; sleeve peeling and thermal shrinkage are carried out on the to-be-repaired cell according to a new processing batch, a cell printing batch number is established again and corresponding and continuous bar code information in a descending order is printed and is inputted into the database, a secondary identifier is generated at a corresponding position in initial inputting information of the to-be-repaired cell in the database according to the one-to-one correspondence relation, so that the same cell has original process data and after-repairing data; and secondary sorting and cell testing are carried out on the cell needing repairing, and then assembling and sorting are carried out on the cell based on the original process data and the after-repairing data. With the method, the yield can be substantially improved and the manufacturing cost can be lowered.

Description

technical field [0001] The invention belongs to the technical field of battery treatment, and in particular relates to a battery online rework processing method. Background technique [0002] At present, during the production process of cylindrical lithium-ion batteries, operations such as internal resistance and voltage tests, capacity classification and other operations are required to finally determine the battery level, and qualified batteries are finally shipped. In the original process, the battery is usually in batches, with 256 pallets as the smallest unit carrier for battery turnover, transportation, and testing. During the production process, the internal resistance, voltage, and capacity tests are completed in sequence, and then assembled and sorted according to different customer requirements. , Batteries that pass the appearance inspection are finally shipped. During this process, rework is required due to poor battery appearance or defects; and test data misju...

AI Technical Summary

Problems solved by technology

From the above flow chart, it can be clearly seen that during the operation process, the bad repaired batteries cannot be re-screened in a timely and effective manner, forming a backlog in the field and warehouse, and will eventually be processed as downgraded products. Under the original operation mode, the batteries after Testing, sorting, inspection and other processes, the final test qualified batteries are ready to be shipped, and the batteries with poor appearance and unqualified electrical properties during the processing can only be picked out as unqualified products, and can not be repaired in time and shipped as normal products

This will affect the production efficiency of the battery, and is not conducive to the continuous operation of the operator. At the same time, it will increase the battery manufacturing cost and decrease the battery yield rate.
