Title:
ELECTRODE SHEET CUTTING CONTROL METHOD AND DEVICE, CONTROLLER AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2023/207150
Kind Code:
A1
Abstract:
An electrode sheet cutting control method and device, a controller and a storage medium. The method comprises the following steps: acquiring median line position information of a first tab and median line position information of a second tab, the median line position information being information calculated according to first position information of a tab rising edge and second position information of a tab falling edge of the first tab or the second tab detected by a detection module, and the second tab being a previous tab of the first tab; calculating a first tab interval distance according to the median line position information of the first tab and the median line position information of the second tab; and determining current position information as target position information under the condition that the first tab interval distance meets a preset distance condition; and determining cutting position information according to the target position information, and controlling a cutting module to cut an electrode sheet. The method can effectively avoid the influence of material belt fluctuation on detection, a cutting position is more accurate, and cutting precision is improved.
