Problems solved by technology

[0003] The disadvantages of the bag-making type cutting and stacking all-in-one machine are: low efficiency of sheet production, high rejection rate of short-circuit detection of manufactured cells
The lamination disadvantages of the "Z-shaped" all-in-one cutting and stacking machine are: the production efficiency is low, and the separator is subjected to tension, which is easy to damage the diaphragm

Embodiment

[0044] figure 1 For the overall flow diagram of the laminated cell forming system provided by the embodiment of the present invention, please refer to figure 1 shown.

[0045] The laminated cell forming system provided by the embodiment of the present invention includes a sheet making device 10, a thermal lamination device 20, a lamination device 30, and a thermal pressing device 40, which are used for thermal compound cutting and lamination in the manufacturing process of lithium power battery packs. The battery forming method of the process.

[0046] Wherein, the sheet making device 10 is in the process of cutting off the pole piece through the pole piece cutting mechanism 118 in the first pole piece making equipment 11 and the pole piece cutting mechanism 118 in the second pole piece making equipment 13. The film belt always keeps running at a constant speed, which greatly improves the production efficiency. The thermal lamination device 20 is used to heat and roll the b...

Abstract

The invention discloses a laminated battery cell forming system, and relates to the technical field of battery cell manufacturing. The system comprises a piece making device, and the piece making device comprises first pole piece making equipment, a membrane assembly and second pole piece making equipment. The membrane assembly comprises middle membrane equipment and bottom membrane equipment, andthe middle membrane equipment is located between the first pole piece manufacturing equipment and the second pole piece manufacturing equipment and used for laying a middle membrane material strip, and the bottom membrane equipment is located at the side, away from the first pole piece manufacturing equipment, of the second pole piece manufacturing equipment and used for laying a bottom membranematerial strip. The first pole piece manufacturing equipment and the second pole piece manufacturing equipment are respectively used for cutting the pole piece material strips into a first pole pieceand a second pole piece with fixed lengths, so that the first pole piece, the middle membrane material strip, the second pole piece and the bottom membrane material strip form a battery cell materialstrip. The system improves the piece production efficiency, and an isolating membrane is not liable to damage, thereby improving the cell short-circuit detection qualification rate, and improving thecell precision.

Description

technical field [0001] The invention relates to the technical field of battery cell manufacturing, in particular to a stacked cell forming system. Background technique [0002] At present, with the industry, lithium battery manufacturers have higher and higher requirements for battery production efficiency, battery performance, and accuracy. However, in the manufacturing process of lithium-powered battery packs on the domestic market, the forming methods of laminated batteries are roughly divided into two types: 1. The lamination system of the bag-making type cutting and laminating machine; 2. "Z-shaped" cutting The lamination system of the all-in-one machine. [0003] The disadvantages of the bag-making type cutting and stacking all-in-one machine are: the efficiency of sheet production is low, and the short-circuit detection rate of the finished batteries is high. The lamination disadvantages of the "Z-shaped" all-in-one cutting and laminating machine are: the production...
