Problems solved by technology

[0003] In the production process of polymer lithium-ion batteries, due to the symmetry of the edge distance between some models of aluminum tabs and nickel tabs, many production failures will occur in the prior art. The direction of the core, the top sealing equipment does not have the function of identifying the front and back, and the cell is scrapped after packaging; the tabs of the bare cells are bent and warped during the transportation, and the tabs are packaged with poor packaging, and the tabs are skewed, resulting in fatal bad leakage; There is no precise positioning of the cell, and the transfer is pushed forward by the offset push plate of the Taidian core, and the corner of the cell head is damaged and an internal short circuit occurs
The emergence of these phenomena greatly affects the production efficiency
[0004] In summary, there are defects in related technologies, which are not conducive to industrial production and need to be improved urgently.

Description

technical field [0001] The invention belongs to the technical field of batteries, and in particular relates to a detection system and a working process with the function of ear shaping. Background technique [0002] According to the different electrolyte materials used in lithium-ion batteries, lithium-ion batteries are divided into liquid lithium-ion batteries (Liquified Lithium-Ion Battery, referred to as LIB) and polymer lithium-ion batteries (Polymer Lithium-Ion Battery, referred to as PLB) or plastic lithium-ion batteries. Ion batteries (Plastic Lithium Ion Batteries, referred to as PLB). The positive and negative electrode materials used in polymer lithium-ion batteries are the same as liquid lithium ions. The positive electrode materials are divided into lithium cobaltate, lithium manganese oxide, ternary materials and lithium iron phosphate materials. The negative electrode is graphite, and the working principle of the battery is also basic. unanimous. The main dif...
