A diaphragm detection method includes acquiring a target image of an electrode plate to be detected. The electrode plate to be detected includes an anode electrode plate and diaphragms respectively stacked on two sides of the anode electrode plate. The method further includes performing image processing on the target image to determine a target image region in the target image, and performing diaphragm misalignment detection on the electrode plate to be detected based on the target image region.

Diaphragm detection method, device and apparatus

A dimension detection method for a battery composite surface includes: acquiring image information of a cathode sheet, the image information including an image of a first surface of the cathode sheet and an image of a second surface opposite to the first surface; acquiring image information of a composite sheet which includes a non-composite surface and a composite surface, the non-composite surface being formed by compounding the first surface of the cathode sheet, an anode, and a separator, the composite surface being formed by compounding the second surface of the cathode sheet, the anode, and the separator, and the image information of the composite sheet including image information of the non-composite surface; and calculating dimension information of the composite surface by an image processing algorithm, according to the image information of the cathode sheet and the image information of the composite sheet.

Method, device, and system for detecting size of battery composite surface

Provided are a method and device for correcting positions of tabs of an electrode assembly. The electrode assembly includes anode electrode plates and cathode electrode plates stacked alternately in a first direction. The method includes: determining whether there are a plurality of consecutive tabs misaligned with each other in a first electrode plate assembly; and adjusting, if there are a plurality of consecutive tabs misaligned with each other, a cutting position of the first electrode plate assembly to adjust a width of first electrode plates obtained after cutting, such that tabs of a plurality of first electrode plates obtained after cutting the first electrode plate assembly are aligned with each other, the first electrode plates being anode electrode plates or cathode electrode plates.
