Description

Technical Field

[0001] The utility model relates to the technical field of soft-pack lithium battery processing, in particular to an overall lateral electric adjustment mechanism for a PCB board on a multi-channel soft-pack battery hot pressing fixture. Background Art

[0002] Currently, the contact point between battery cells and PCB boards is usually achieved through a traditional rack-and-pinion rotation mechanism. This mechanism requires a large space for rotation, and the flip mechanism causes the product to flip over a large range. This results in a large contact point between the battery cells and PCB boards during rotation, which limits production efficiency and makes it difficult to guarantee product quality, significantly impacting the company's profits and product competitiveness.

[0003] In actual production, the incoming soft-pack battery cells need to be rotated according to the requirements of different soft-pack battery modules to adjust their polarity so as to form different parallel or series combinations of soft-pack battery modules.

[0004] There are two existing methods for rotating the contact position between the soft-pack battery cell and the PCB board. One is manual operation, which not only has low production efficiency but also low accuracy. The other is to use mechanical equipment for rotation. After the soft-pack battery cell is produced on the line, it needs to be transferred to an independent rotating mechanism for rotation instead of being rotated on the original line. This causes the interruption of automated production and low production efficiency. In addition, due to the characteristics of the soft-pack battery cell that is easy to damage and deform, the soft-pack battery cell is transferred multiple times during the transfer process, which is easy to cause quality problems of the soft-pack battery cell.
