Technical parameters and characteristics of 18650 battery flat top winding machine equipment

　　18650 battery flat top winding machine

　　Winding machines can be divided into manual winding machines, semi-automatic winding machines and fully automatic winding machines according to the machine operation mode. As far as 18650 battery flat top winding machines and capacitor winding machines are concerned, buyers usually classify them according to their place of origin, which are mainly divided into: domestic winding machines, Korean winding machines, and Japanese winding machines. Generally, small-scale battery manufacturers will choose domestic winding machines, mainly because of the low price. The winding machines used by battery manufacturers that receive large orders basically use Korean winding machines and Japanese winding machines.

　　In recent years, KOEM's 18650 battery flat top winding machines and capacitor winding machines from South Korea have occupied a large market share. First of all, because the technology is mature and stable, the price is affordable, and the after-sales service is timely. Coupled with the impact of disputes between Japan and our country, the market share of Korean winding machines is growing.

　　18650 battery flat top winding machine equipment features

　　1. Single-station winding is used to effectively ensure the consistency of the battery core.

　　2. The reel is a floating winding method, which makes the angular speed of the winding needle uniform during the winding process of the square battery core, thereby effectively controlling the S-shaped deformation of the battery core.

　　3. Both the diaphragm and the pole piece adopt constant tension control. The tension is not affected by changes in the motor and air pressure, and it overcomes the tension impact caused by winding and unwinding.

　　4. The pole piece is pre-rolled by the guide wheel and is sold directly from the iron core winding machine manufacturer, which effectively ensures the pole position of the battery core.

　　5. Gluing method: first stick the tape on the tail of the positive electrode according to the size required by the process. After the battery core is wound, it will automatically wrap the battery core. When applying glue in this way, first the appearance of the battery core will be smooth. The winding machine manufacturer does not

　　The traditional glueing method will cause wrinkles on the outer pole piece. Secondly, less tape can be used to wrap the battery core, which not only saves tape, but also reduces the thickness of the battery core.

　　6. The rolling needle adopts an adjustable method. The width of the rolling needle can be adjusted according to the production requirements, and the specification can be changed quickly and easily.

　　7. The positive and negative pole pieces adopt double correction precision mechanisms to ensure the alignment of the pole pieces and reduce short circuits caused by human operations during the winding process.

　　Foreign companies with 18650 battery flat top winding machine equipment have a long history of technology development and high brand effect, but the production process is relatively solid. Most of them only provide standardized testing systems, which cannot meet the customized needs of domestic customers. Moreover, most foreign companies only rely on agents for sales, and their domestic service capabilities are weak. Domestic manufacturers are flexible, cost-effective, and more competitive. The domestic production rate of activation volumetric detection equipment has exceeded 90%. If domestic 18650 battery flat top winding machine equipment brands want to have more markets, they will have to compete more with their own domestic brands.
