Abstract

The invention discloses a pole piece forming device and a battery cell production system, and relates to the technical field of battery production. The pole piece forming device comprises a controller, a conveying mechanism, a cutting mechanism, a forming mechanism and a traction mechanism, and the conveying mechanism, the cutting mechanism and the forming mechanism are sequentially arranged in the first horizontal direction. The conveying mechanism is used for clamping and conveying composite unit pole pieces in the first horizontal direction. The traction mechanism is used for clamping the composite unit pole piece output by the conveying mechanism, and performing traction in a first horizontal direction; the controller is electrically connected with the cutting mechanism and the traction mechanism; and the controller is used for controlling the cutting mechanism to cut off the composite unit pole piece when the traction mechanism pulls the composite unit pole piece to move for a preset distance, and controlling the traction mechanism to release the clamping of the composite unit pole piece, so that the cut composite unit pole piece falls onto the forming mechanism under the action of gravity to finish preliminary folding. According to the pole piece forming device provided by the invention, the lamination speed is increased, and the energy consumption is reduced.

Description

technical field [0001] The invention relates to the technical field of battery production, in particular to a pole piece forming device and a battery cell production system. Background technique [0002] At present, in the preparation process of lithium-ion batteries, the pole piece forming devices used mainly include two types of equipment: free lamination and zigzag lamination. The free lamination mainly uses a manipulator to stack a single pole piece, which is inefficient and cannot achieve high speed. laminations. The zigzag lamination mechanism itself has a large mass, and the energy consumption is relatively high in the process of moving left and right. The two lamination equipment have been difficult to meet the needs of battery preparation. [0003] Therefore, there is an urgent need for a pole piece forming device to improve lamination efficiency and reduce energy consumption. Contents of the invention [0004] The object of the present invention is to provide ...
