Abstract
The invention provides a battery, a power utilization device and a welding deviation detection device and a method thereof, and belongs to the technical field of battery manufacturing. A pre-welding addressing mechanism can determine the relative position relation between a positioning hole in a battery and a plurality of pole columns and send the relative position relation to the welding mechanism and the post-welding detection mechanism. The welding mechanism can detect the first positions of the positioning holes and determine the first positions of the plurality of pole columns based on the first positions of the positioning holes and the relative position relation, so that the welding mechanism can accurately weld a confluence assembly and the plurality of pole columns based on the first positions of the plurality of pole columns to form a plurality of welding seams. The post-welding detection mechanism can detect the second position of the positioning hole and the positions of the multiple welding seams, and the welding deviation condition of the confluence assembly and the pole column is detected based on the second position of the positioning hole, the positions of the multiple welding seams and the relative position relation. According to the embodiment of the invention, the confluence assembly and the plurality of pole columns can be accurately welded through the welding mechanism, and the welding deviation condition can be simply, conveniently and timely detected through the post-welding detection mechanism.
Description
technical field [0001] The embodiments of the present application relate to the technical field of battery manufacturing, and in particular to a battery, an electrical device, a welding deviation detection device and a method. Background technique [0002] In the production process of the power battery, it is necessary to weld the multiple poles of the multiple battery cells in the battery together with the bus assembly to realize the electrical connection of the multiple battery cells. If the bus assembly is offset from the pole, it will affect the safety performance of the battery. In related technologies, there are many studies on how to improve the accuracy of the welding position, and there are few studies on the detection of welding quality. Therefore, a welding deviation detection device is urgently needed to detect the welding deviation of the bus assembly and the pole. In order to realize the monitoring of welding quality.
