Flexible assembly edge cutting and searching method and system, edge cutting method and assembly preparation method

By irradiating the flexible module laminate with a specific wavelength excitation light source, the cell array is excited to produce photoluminescence. The images are collected and processed to identify the edges, which solves the problem of inaccurate edge positioning of the cell array under low contrast or special front panel structure, and realizes high-precision, non-contact edge positioning and trimming.

AI Technical Summary

Technical Problem

In low-contrast or special front panel structures, edge positioning of the cell array is inaccurate and unreliable, and traditional visual recognition methods struggle to achieve high-precision edge positioning.

Method used

A specific wavelength excitation light source is used to irradiate the flexible module laminate, causing the cell array to produce photoluminescence. The luminescent image is acquired and processed by an image acquisition module to identify the boundary between the luminescent and non-luminescent areas and determine the edge of the cell array.

Benefits of technology

It achieves high-precision, non-contact edge positioning, solving the problem of inaccurate edge positioning of battery cell arrays under low contrast or special front panel structures, and improving the accuracy and production efficiency of subsequent edge trimming.
