In the current market or production, the two ends of a welding strip welded on a front main grid line and a back main grid line of a poor sheet are manually cut off, then the welding strip on a good sheet and the cut welding strip are manually welded, and due to the fact that the splicing of the welding strip can affect the current gathering and the appearance is not attractive, a plurality of manufacturers require to replace the poor sheet in a battery string through a new process. In view of the above, the application provides a device and a method for repairing a battery string assembly, which can heat and separate welding strips required to be separated when a bad piece is replaced, and then weld the welding strips required when a good piece is replaced, so that the problems caused by cutting and splicing the welding strips are avoided, and the quality of the battery string after repair is improved. The following explains the battery string component repair device provided by the present application with reference to fig. 1A and 1B.

Like this, through setting up the metal silk thread, can separate a plurality of separation welding strips of welding on the battery piece simultaneously, improved the separation efficiency of welding the area.
In an alternative implementation, referring to fig. 1A, the heating device includes a first heating tip 21 and a second heating tip 22, wherein: the first heating head 21 heats the first solder strip section soldered on the front main grid line of the first cell 11 to separate the solder strip section from the front main grid line of the first cell 1111; the second heating head 22 heats the second solder strip section welded to the front main grid line of the third cell 1212 to separate the second solder strip section from the front main grid line of the third cell 12, the third solder strip section and the second solder strip section on the back main grid line of the first cell 11 are two parts of the same solder strip, and the solder strip is welded on the back main grid line of the second cell before replacement.

For example, the first solder strip fixing device 31 is used for fixing a set of solder strips separated from the front main grid lines of the first battery piece 11, and the second solder strip fixing device 32 is used for fixing a set of solder strips separated from the back main grid lines of the first battery piece 11. For another example, the first solder strip fixing device 31 is used to fix a group of solder strips separated from the front main grid line of the first cell 11, the second solder strip fixing device 32 is used to fix a group of solder strips separated from the front main grid line of the third cell 12, and the solder strips on the front main grid line of the third cell 12 and the solder strips on the back main grid line of the first cell 11 belong to different parts of the same group of solder strips, that is, the same group of solder strips is soldered to the back main grid line of the first cell 11 and the front main grid line of the third cell 12.
