Thermal compounding high-speed stacking machine

Abstract

The invention provides a thermal compounding high-speed stacking machine. The invention relates to the technical field of lithium battery manufacturing. The thermal compounding high-speed stacking machine comprises a supporting wall plate, a pole piece manufacturing device and a stacking device. The pole piece manufacturing device and the stacking device are arranged on the supporting wall plate at an interval. The pole piece manufacturing device is used for forming composite pole pieces. The pole piece stacking device comprises a swing roller assembly and a folding and stacking table, the swing roller assembly is arranged above the folding and stacking table and used for folding and stacking the composite pole pieces to form a battery cell, and limiting baffles are arranged on the two sides of the folding and stacking table so that a groove used for containing the composite pole pieces can be formed in the folding and stacking table. Due to the limiting and stopping effects of the limiting baffles, the battery cell can be stopped and limited from the two sides, loosening of the stacked pole pieces is prevented, and the stacking quality is improved. In addition, due to the fact that the swing roller assembly is adopted for folding and stacking the composite pole pieces, and the limiting baffles are arranged, the folded composite pole pieces can be effectively fixed, the loosening problem of the composite pole pieces does not need to be considered in the stacking process, and the stacking speed is greatly increased.

Description

technical field [0001] The invention relates to the technical field of lithium battery manufacturing, in particular to a thermal compound high-speed lamination machine. Background technique [0002] At present, the lithium-ion battery process can be roughly divided into the following contents: homogenization→coating→rolling→slitting→slicing→making batteries→shelling→liquid injection→formation→volume separation, etc. Winding or stacking equipment is responsible for the production of sheets and cells. There are various traditional stacking methods, but they can be roughly divided into several categories such as single-chip stacking and zigzag stacking. [0003] The disadvantage of the existing technology is that the pole piece cannot be fixed because the pole piece is in a loose state, which easily leads to battery safety issues, and the efficiency of lamination is very low, and the amount of battery cells produced cannot keep up with the market demand. [0004] In view of th...

[0003] The disadvantage of the existing technology is that the pole piece cannot be fixed because the pole piece is in a loose state, which easily leads to battery safety problems, and the efficiency of lamination is very low, and the amount of battery cells produced cannot keep up with the market demand

[0004] In view of this, in order to solve the problems of battery cell safety hazards and low stacking efficiency, it is particularly important to develop a new type of stacking method that can improve the quality of the battery core and greatly improve the stacking efficiency.
