Method, apparatus, device, medium and product for detecting alignment of battery electrode plates

A method for detecting alignment of lamination molded battery electrode plates by an alignment detecting apparatus, wherein the alignment detecting apparatus comprises a light sensing device and a data processing device connected to the light sensing device, the method comprising:

• obtaining, by the light sensing device, depth distances of a target cross section of the battery electrode plates, wherein the target cross section is perpendicular to an electrode plate setting direction of the battery electrode plates, and each of the depth distances of the target cross section is corresponding to one of the electrode plates;
• and
• determining, by the data processing device, an alignment detection result of the battery electrode plates based on the depth distances of the target cross section obtained by the light sensing device;
• wherein determining the alignment detection result of the battery electrode plates based on the depth distances of the target cross section comprises:
• based on depth distances of N mark points comprised in the target cross section, determining peak points and trough points among the N mark points, to obtain P peak points and Q trough points, wherein the N mark points correspond to N electrode plates one to one, N is an integer greater than 1, and P and Q are both positive integers;
• and
• determining the alignment detection result of the battery electrode plates based on position information of the P peak points and the Q trough points.
