Preliminary Soldering before Housing
The good battery core is loaded into the aluminum shell, and spot welding is for the subsequent sealing welding of the top cover and the shell. The top cover and the shell are pre-welded and fixed to prevent the dislocation of the top cover from affecting the quality of the battery.
Main control points
The shell station is carried out after the incoming material of the battery core, the equipment carries out positive and negative pressure dust removal and cleaning of the shell, and ensures that there is no foreign matter in the light before entering the shell station into the shell, and the battery core is carried out short circuit test after the short circuit test and pre-fixed welding.
Specific process
Battery Cell Loading: Placing the battery cell on the production line.
Battery Cell Scanning: Scanning the battery cell to confirm its information.
If the result of scanning code is NG (unqualified), NG Removal is performed.
Battery Cell Cleaning: to clean the battery cell.
Aluminum Housing Loading: Placing the aluminum housing on the production line.
Aluminum Housing Cleaning: The aluminum housing is cleaned.
Battery Cell Housing: Put the cleaned battery cell into the battery housing.
Battery Cell Pressing: Pressing the battery cell to ensure that it is fixed in the battery shell.
Step Inspection: Inspect the step part of the battery shell.
If the step detection result is OK, proceed to the next step.
If the result is NG, perform NG subtraction.
Top Cover Pre-welding: The top cover is pre-welded.
HI-pot Inspection: Perform HI-pot inspection on the battery core. If the result of HI-pot inspection is NG, perform NG removal.
Battery Cell Unloading: The removal of assembled battery cells from the production line.
The whole flow chart shows the complete process from the charging of the battery cell to the cleaning of the aluminum shell, including multiple steps such as scanning code, cleaning, pressing, testing and cutting material, as well as the treatment process when the test is not qualified.
