A battery module tab automatic rolling device

Abstract

The invention relates to the technical field of battery production equipment, in particular to an automatic rolling device of a battery module tab. The automatic rolling device comprises a rack, a tool plate, a blocking and stop mechanism, a dual-shaft movement module, clamping mechanisms, a rolling mechanism and a lifting mechanism, wherein the tool plate bears a battery module to be moved to a working position on a transmission line, the blocking and stop mechanism is blocked and stopped by the tool plate, the lifting mechanism is used for pushing the tool plate from the transmission line and raising the tool plate to a required height, the battery module is clamped by the clamping mechanisms arranged at two sides of the battery module, the dual-shaft movement module acts, the rolling mechanism is moved to a position where the tab is located, the tab is rolled according to a sequence, afterwards the clamping mechanisms at the two sides are loosen, the lifting mechanism descends, theblocking and stop mechanism descends, and the battery module is moved to a next station. The device is high in automation, production can be performed instead of labor, the workload of a worker is greatly reduced, the production cost is reduced as well as the production efficiency is improved, and the automatic rolling device is suitable for industrial production.

Description

technical field [0001] The invention relates to the technical field of battery production equipment, in particular to an automatic rolling device for tabs of a battery module. Background technique [0002] Before welding the battery lugs to the copper bar, the battery module must be flattened to make it stick to the surface of the copper bar, otherwise, it will lead to poor welding, false welding, false welding, and even tab welding penetration. The case where the tab is not connected to the copper bar. In the prior art, the tabs are usually flattened by manual rolling, such as making a roller jig, manually pressing on the tabs and rolling back and forth to flatten the tabs. The degree of automation is low, and the labor workload of employees is large, which greatly reduces production efficiency. [0003] In view of this, it is an urgent technical problem in this field to overcome the above defects in the prior art and to provide a new automatic rolling device for tabs of ...
