Abstract

The invention relates to a solder joint positioning method and a solder joint positioning device. The solder joint positioning method comprises the steps of acquiring a first image of a workpiece to be welded, and extracting identifying information of the workpiece to be welded according to the first image; according to the identifying information of the workpiece to be welded and a preset corresponding relation, acquiring second solder joint coordinates and second characteristic point coordinates corresponding to the identifying information; acquiring first characteristic point coordinates onthe first image according to the first image; correcting the second solder joint coordinates according to the first characteristic point coordinates and the second characteristic point coordinates soas to obtain first solder joint coordinates; and identifying a solder joint of the workpiece to be welded according to the first solder joint coordinates. According to the solder joint positioning method, the first image of the workpiece to be welded is acquired through using a vision positioning mechanism in advance, and the solder joint coordinates on the first image can be acquired, so that abasis is provided for adjusting the solder joint coordinates through a welding mechanism in the follow-up process. By adopting the vision positioning mechanism, accurate positioning can be realized, and the reliability of solder joint positioning is improved.

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 fuels as power sources. Usually, new energy vehicles use lithium batteries to power vehicles. With the development of the new energy vehicle industry, the greater the capacity requirements for lithium batteries. At present, a large-capacity lithium battery is composed of a plurality of battery modules, and each battery module includes several small cylindrical cells and a bracket for fixing the cylindrical cells. The positive electrode of each cylindrical battery cell is connected with the positive electrode, the negative electrode is connected with the negative electrode, and the negative electrode of the battery cell is welded to the negative electrode busbar by aluminum wire and electrically ...
