Abstract

The invention relates to a welding point positioning method and a welding point positioning device. Wherein, the welding spot positioning method includes: obtaining the first image of the workpiece to be welded, and extracting the identification information of the workpiece to be welded according to the first image; according to the identification information of the workpiece to be welded and the preset corresponding relationship, obtaining the The second welding point coordinates and the second feature point coordinates; the first feature point coordinates on the first image are obtained according to the first image; the second welding point coordinates are corrected according to the first feature point coordinates and the second feature point coordinates to obtain the first feature point coordinates A welding point coordinate; identifying the welding point of the workpiece to be welded according to the first welding point coordinate. In the above welding point positioning method, by using the visual positioning mechanism to collect the first image of the workpiece to be welded in advance, the coordinates of the welding points on the first image can be obtained, which provides a basis for the subsequent welding mechanism to adjust the coordinates of the welding points. The visual positioning mechanism can be used for precise positioning, which improves the reliability of solder joint positioning.

Description

technical field [0001] The invention relates to the technical field of welding positioning, in particular to a welding point positioning method and a welding point positioning device. Background technique [0002] New energy vehicles refer to vehicles that use unconventional vehicle fuel as a power source. Usually new energy vehicles use lithium batteries to power the vehicle. With the development of the new energy vehicle industry, the capacity requirements for lithium batteries are greater. At present, a large-capacity lithium battery is composed of multiple battery modules, and each battery module includes several small cylindrical cells and a bracket for fixing the cylindrical cells. The positive pole of each cylindrical electric core is connected with the positive pole, and the negative pole is connected with the negative pole. At the same time, the negative pole of the electric core is welded to the negative bus bar through the aluminum wire and electrically connected...
