Abstract

The invention aims to provide lithium battery stacking equipment. The lithium battery stacking equipment comprises a positioning device and a stacking device, wherein the positioning device comprises a main body and a positioning piece fixed on the main body; the positioning piece defines a positioning region on the main body and is used for positioning a pole piece body in the positioning region; the stacking device is a hollow frame structure, defines a body region and a limiting region which extends from the body region and communicates with the body region; and the body region and the limiting region jointly form a penetration region and are respectively matched with a main body and a pole lug of a pole piece. When the lithium battery stacking equipment is used, the stacking device is stacked on the positioning device, corners of the stacking device is combined to positioning pieces of the positioning device in a clamped manner, and the limiting region of the stacking device is staggered from the pole lug of the pole piece positioned on the positioning device in the stacking direction of the stacking device and the positioning device. The invention further provides a stacking method using the lithium battery stacking equipment. The lithium battery stacking equipment has the advantages of simplicity and convenience in operation, accurate positioning, high efficiency and improvement of yield of products.

Description

[0001] 【Technical field】 [0002] The invention relates to the field of batteries, in particular to a lithium battery stacking device and a stacking method thereof. [0003] 【Background technique】 [0004] In the production process of lithium batteries, it is necessary to cut large pieces of aluminum foil and copper foil into small pieces of positive and negative electrodes. Both the positive and negative electrodes include a body and a tab extending from one end of the body. A diaphragm is provided on the body to separate the adjacent bodies insulated. The tab has no diaphragm, and the tab is electrically connected to an external power source or electrical equipment to realize charging and discharging. The stacking operation is to alternately stack the positive and negative electrodes of the lithium battery according to the required position, so as to facilitate the subsequent processes of liquid injection and chemical formation. In the prior art, the manual stacking method ...
