    摘要: A cell detection method and apparatus, a system, a computer device, a computer-readable storage medium, a computer program product, and a cell detection system are provided. The method includes: obtaining, by shooting, a cell picture of a cell obtained after tab welding, the cell picture being shot under illumination of a shadowless light source; determining a detection object in the cell picture; and performing defect detection based on the detection object to obtain detection result information. In this method, the cell picture of the cell obtained after tab welding is shot under illumination of the shadowless light source, which can reduce a risk of false detection due to an impact of light spots caused by slight bending of an adapter plate, thereby improving the accuracy of defect detection on the cell that is obtained after tab welding.

    摘要: An electrode core encasing apparatus includes a main power mechanism, a housing fixing mechanism, an encasing mechanism, and an electrode core fixing mechanism. The housing fixing mechanism is disposed on one side of the encasing mechanism, which is located between the housing fixing mechanism and the electrode core fixing mechanism. The encasing mechanism includes an encasing mechanism body and an XY floating slide block. Two ends of the XY floating slide block are connected to the main power mechanism and the encasing mechanism body, respectively. The XY floating slide block is configured to drive the encasing mechanism body to slide freely relative to the main power mechanism, so as to adjust a relative position between the housing and the electrode core. The main power mechanism is configured to drive the housing fixing mechanism and the encasing mechanism to move to sleeve the electrode core into the housing.

    摘要: An electrode plate detection apparatus, method and system are disclosed. The electrode plate detection apparatus includes a detection module and a first image acquisition module. The first image acquisition module is configured to acquire images of different coating regions on an electrode plate, and send the images of the different coating regions to the detection module. The detection module is configured to detect the electrode plate according to the images of the different coating regions. As the first image acquisition module can be configured to implement the acquisition of the images of the different coating regions on the electrode plate, compared with the need to use different image acquisition modules for different coating regions, the number of the image acquisition modules can be reduced, thereby reducing the cost of the electrode plate detection apparatus.
