Method, device, welding equipment and readable storage medium for obtaining welding point

Abstract

Embodiments of the present invention provide a welding point acquisition method, device, welding equipment and readable storage medium, which relate to the technical field of machine vision. The method determines the first coordinates of the first feature point, the first coordinates of the second feature point, and the first coordinates of the battery according to the first coordinate system corresponding to the plane information to be welded, Information, convert the first coordinates of the first feature point and the first coordinates of the second feature point to obtain the second coordinates of the first feature point and the second coordinates of the second feature point, and then according to the first feature point The second coordinate, the second coordinate of the second feature point, and the first coordinate of the battery cell are obtained to obtain the second coordinate of the battery cell, and the second coordinate of the battery cell is the welding point that needs to be obtained, which realizes fast and accurate Get the welding point.

Description

technical field [0001] The present invention relates to the technical field of machine vision, in particular to a method, device, welding equipment and readable storage medium for acquiring welding point positions. Background technique [0002] In the battery cell module welding process, because of the large number of cells in the cell module, the traditional positioning method is to set fixed points, and when setting the fixed points, the operator needs to check each cell one by one. The coordinate point position of the core requires a lot of work, and the requirements for the consistency of the battery module are very high, otherwise there will be problems such as inaccurate positioning and damage to the module caused by the welding deviation of the battery core, and the loss of the point position will cause re-calibration positioning problem. Contents of the invention [0003] In view of this, the object of the present invention is to provide a welding point acquisitio...
