1. A welding deviation detection device, comprising:
a pre-welding addressing mechanism, configured to determine relative position relations between location holes and a plurality of poles in a battery, and to send the relative position relations to a welding mechanism and a post-welding detection mechanism, wherein the location holes are disposed on end plates of the battery along a first direction;
the welding mechanism, configured to detect first positions of the location holes, to determine first positions of the plurality of poles based on the first positions of the location holes and the received relative position relations, and to weld a bus assembly to the plurality of poles based on the first positions of the plurality of poles to form a plurality of welds; and
the post-welding detection mechanism, configured to detect second positions of the location holes and positions of the plurality of welds, and to detect welding deviation situations of the bus assembly and the poles based on the second positions of the location holes, the positions of the plurality of welds and the received relative position relations.
