Description

Technical Field

[0001] The utility model relates to the technical field of battery string production, in particular to a welding strip buffer mechanism. Background Art

[0002] The utility model patent CN215363984U discloses a multi-roll welding tape feeding device, which includes a reel arrangement mechanism, a welding tape separation mechanism, a passing wheel, a guide wheel and a heavy hammer, wherein the reel arrangement mechanism is used to place the welding tape reel and provide welding tape, and the welding tape separation mechanism is used to separate the multiple welding tapes wound on the passing wheel, and the multiple welding tapes pass through the passing wheel, the guide wheel and the heavy hammer in sequence to enter the next process. The heavy hammer is used to cache part of the welding tape segment for the battery string production equipment to continuously produce battery strings. After replacing the welding tape reel, the welding tape on the replaced welding tape reel needs to be manually threaded on the passing wheel, the guide wheel and the heavy hammer in sequence. When there are many grid lines on the battery cell used to produce the battery string and they are densely distributed, the same number of welding tapes need to be threaded on the heavy hammer, and the spacing between the welding tapes is the same as the spacing between the grid lines. Because the distance between the welding tapes is too close, it is difficult to thread the welding tape manually due to space limitations, and the welding tape threading takes a long time.
