A kind of glue wrapping device for aluminum shell battery cell

Abstract

The invention discloses an aluminum case battery unit glue wrapping device, which comprises a bottom plate, a rubber roller and a film support, the rubber roller and the film support are arranged at one end of the bottom plate, and a film is arranged on the film support; the bottom plate The middle part is provided with a positioning plate and a knife groove; the positioning plate is L-shaped, wherein the long plate of the positioning plate is fixedly arranged along the edge of one side of the bottom plate, and the short plate of the positioning plate is parallel to the knife groove; wherein the short plate of the positioning plate There is a certain distance between the bottom of the plate and the bottom plate; and the knife groove is set perpendicular to the conveying direction of the tape. The device has simple structure, low cost, and low requirements for operators; it can accurately complete the positioning of the tape and the surface of the battery, and accurately cut the required length of tape to avoid material waste and achieve efficient continuous operation; steps It is simple and efficient, greatly improving the consistency of the lagging, and avoiding the problems of shell contact and subsequent poor welding caused by lagging offset.

Description

technical field [0001] The invention relates to the field of lithium-ion battery manufacturing, in particular to an aluminum-shell battery monomer encapsulation device. Background technique [0002] In the production process of batteries, encapsulation is an important factor that is indispensable and affects its quality and life. In the manufacturing process of lithium-ion battery PACK, the surface insulation tape is directly related to the performance of the entire battery module, and even more related to the safety performance of the whole vehicle when it is subsequently applied to the car. [0003] The use of a fully automated rubber encapsulation device has high costs and high requirements for operators; and in the production process, the production method of small batches and multiple varieties increases the difficulty of introducing a fully automated rubber encapsulation device. Therefore, in most cases, people mostly use manual insulating tape to wrap the work. Howev...

[0003] The use of a fully automated rubber encapsulation device has high costs and high requirements for operators; and in the production process, the production method of small batches and multiple varieties increases the difficulty of introducing a fully automated rubber encapsulation device.

Therefore, in most cases, people mostly use manual insulating tape to wrap the work. However, due to the lack of special auxiliary devices, the work efficiency is low and the defect rate increases. and other adverse conditions will bring greater difficulty to the subsequent automatic welding operation and increase the safety hazard of the entire battery system
