Abstract

The invention relates to a welding detection system and method. The welding detection system includes: a welding head, a transmission device and a detection device, the detection device is fixed on the welding head, the transmission device is connected to the detection device, wherein the transmission device is connected to the welding wire, and the One end of the welding wire is in contact with the welding head; the detection device is used to detect the welding state according to the pressure action generated by the welding wire on the transmission device when the welding head is raised. The detection device of the welding detection system is used to detect the welding state according to the pressure action generated by the welding wire on the transmission device when the welding head is lifted, so that after the welding is completed, the pressure action generated by the welding wire on the transmission device can be driven when the welding head is lifted. The welding status is detected in time, and re-soldering can be completed in time after the detection of false welding, reducing or even avoiding the problem of false welding, and improving the safety and stability of the power battery module.

Description

technical field [0001] The invention relates to the field of power battery module welding, in particular to a welding detection system and method. Background technique [0002] With the rapid development of power battery technology, power batteries have become the main source of power for electric vehicles, electric bicycles and other tools. Usually, when the power battery is used as the power source, the power battery needs to be welded to form a power battery module, and the power battery module is used to provide power for electric vehicles, electric bicycles and other tools. [0003] The traditional power battery module welding technology uses aluminum wire to weld the power battery to form a power battery module with high energy density and long life. [0004] However, the traditional power battery module welding technology cannot detect the welding status in time, which leads to the problem of virtual welding in the power battery module.
