Title:
BATTERY CELL DETECTION SYSTEM AND BATTERY CELL DETECTION METHOD
Document Type and Number:
WIPO Patent Application WO/2024/093644
Kind Code:
A1
Abstract:
The present application relates to a battery cell detection system and a battery cell detection method. The system comprises an image acquisition module and a processor. The image acquisition module is used for acquiring a first battery cell image and a second battery cell image of a laminated battery cell undergoing hot pressing. The first battery cell image is used for positioning electrode sheets, and the second battery cell image is used for reconstructing the electrode sheets. The processor is used for recognizing the position of an anode sheet and the position of a cathode sheet according to the first battery cell image, obtaining a flatness parameter of the laminated battery cell according to the position of the anode sheet, the position of the cathode sheet and the second battery cell image, and according to the flatness parameter, confirming whether the laminated battery cell has a defect. By means of the system, Overhang value measurement between an anode sheet and a cathode sheet of a laminated battery cell and surface inclination degree measurement of the laminated battery cell can be implemented at the same time, thereby effectively improving the accuracy of defect detection of the laminated battery cell, and avoiding the phenomena of missing detection and overkill.
