Soft package lithium battery protection plate mounting equipment

Abstract

The invention discloses soft package lithium battery protection plate mounting equipment which comprises a rolling block assembly arranged corresponding to a single row of battery cell tabs on a protection plate, and a driving assembly connected with the rolling block assembly and used for driving the rolling block assembly to roll the battery cell tabs; and the rolling block assembly comprises a plurality of ball modules for bending the battery cell tabs through rolling. According to the soft package lithium battery protection plate mounting equipment, battery cell tabs are bent to a bonding pad through two-time opposite-direction actions of the driving assembly and in a rolling mode of a plurality of ball modules on the rolling block assembly, follow-up welding installation is facilitated, labor can be saved through the arrangement mode, the production procedures are reduced, and therefore, the production efficiency is improved and the production cost is reduced.

Description

technical field [0001] The invention relates to the technical field of lithium batteries, in particular to a soft-pack lithium battery protection board installation device. Background technique [0002] Compared with lead-acid batteries, lithium batteries have higher energy density, longer cycle life, higher lithium ion activity, and faster charging speed, but lithium batteries have poor safety performance. They need to be connected in series and parallel to form a group and then connected to an external protection circuit to control the battery. Soft-pack lithium batteries are connected in series and parallel. In the process of forming a module, the battery protection board generally needs to collect battery information, battery status, control circuit on-off and other functions. At present, the more advanced method is to directly weld the protective plate and the positive and negative tabs of the battery into one body. [0003] In the prior art, after the cells are stacke...

Problems solved by technology

The current method is to manually knock the tabs flat with an insulating block and then weld them. For example: 1 and 13 strings of cell protection boards need to be tapped at 26 tabs, which takes more than 2 minutes. The number of cores and the number of tabs are large, and the way of knocking tabs will lead to low production efficiency and long production cycle

[0004] Therefore, how to avoid the low production efficiency caused by manually knocking on the tabs is a technical problem that those skilled in the art need to solve at present.
