High-speed automatic adhesive coating machine for lithium ion battery core

Abstract

The objective of the invention is to provide a high-speed automatic adhesive coating machine for a lithium ion battery core, wherein the machine has a reasonable structure and high production efficiency and is capable of substantially increasing the degree of automation. The high-speed automatic adhesive coating machine comprises a frame; an electric control part, a working platform and a vertical plate (4) are arranged on the frame; the vertical plate (4) is provided with an adhesive coating device which comprises an adhesive paper output part (a), an adhesive coating part (b) and a core clamping part (c). The adhesive paper output part (a) outputs adhesive paper; after the adhesive paper is pulled out to a certain length and cut, the adhesive coating part (b) adsorbs the non-sticky surface of the cut adhesive paper and conveys the cut adhesive paper to the core clamping part (c); under the action of the electric control part, the sticky surface of the cut adhesive paper faces a to-be-coated position of the core; and the adhesive coating part (b) and the core clamping part (c) complete adhesive coating together. The high-speed automatic adhesive coating machine provided by the invention is applicable to the field of manufacturing of batteries.

Description

technical field [0001] The invention relates to a glue wrapping machine, in particular to an automatic glue wrapping machine for high-speed lithium-ion battery cells. Background technique [0002] The rechargeable battery consists of a protective circuit board and battery cells. Wherein, the battery cell is the power storage part in the rechargeable battery. The quality of battery cells directly determines the quality of rechargeable batteries. There are many structures of battery cells, one of which is wrapped by several layers of diaphragms and aluminum films, and two electrodes are installed at one end of the wrapped soft package, and then surrounded by aluminum sheets, such as figure 1 Shown is the cell surrounded by the aluminum sheet. In the production process of the existing battery cells, in order to ensure the quality of the subsequent battery production, two layers of glue need to be wrapped on both ends of the battery cells surrounding the aluminum sheet to mak...

Problems solved by technology

However, the method of artificial encapsulation has the following disadvantages: 1. It requires a lot of manpower to work, which increases production costs; 2. The staff need to work without interruption, which increases the labor intensity of the staff; 3. Artificial encapsulation will reduce Production efficiency; 4. Manual encapsulation cannot guarantee the consistent quality of each encapsulated battery cell, resulting in uneven quality of battery cells; 5. Manual encapsulation reduces the automation of the entire battery production
