Abstract

The invention relates to the technical field of lithium battery production, and discloses a lithium battery Z-shaped lamination device. The lithium battery Z-shaped lamination device comprises a fixing frame, a negative pole piece lifter, a positive pole piece lifter, an isolating membrane, a motor and an air pump; the fixing frame can be divided into three parts including a side plate, a top plate and a bottom supporting plate, and a battery negative pole piece is movably mounted in the negative pole piece lifter; and a battery positive pole piece is movably mounted to the position, the positive pole piece lifter, in the fixing frame, and a negative pole piece conveying device is movably mounted on a top plate of the fixing frame. Through arrangement of the negative pole piece conveying device and the positive pole piece conveying device, the battery negative pole piece and the battery positive pole piece which need to be laminated are quickly mounted on the isolating membrane at a time, so that the pole piece conveying time is shortened, and the laminating efficiency is improved; and meanwhile, due to synchronism of the negative pole piece conveying device and the positive pole piece conveying device, the position difference of each pole piece after installation is small, so that the error between the pole pieces is small, and the quality of battery pieces is effectively improved.

Description

technical field

[0001] The invention relates to the technical field of lithium battery production, in particular to a zigzag lamination device for lithium batteries. Background technique

[0002] Lithium battery is a kind of negative electrode material with lithium metal or lithium alloy. The primary battery using non-aqueous electrolyte solution is different from rechargeable lithium-ion battery and lithium-ion polymer battery. Lithium battery is a kind of reaction with high efficiency and safety. Energy batteries with strong performance and small size are more and more widely used. In the production process of lithium batteries, it is necessary to stack the positive and negative electrode sheets to form battery sheets. The stacking of electrode sheets has been done by Manually switch to a fully automatic lithium battery stacker for stacking, but the currently used stacker has some shortcomings in production, as follows:

[0003] The existing stacking machine adopts the me...
