Battery Winding Machine Equipment Technical Parameters and Features

12V27A battery Winding Machine

According to the machine operation mode, the winding machine can be divided into: manual winding machine, semi-automatic winding machine, and fully automatic winding machine. As for 12V27A battery winding machines and capacitor winding machines, buyers usually classify them according to the place of origin, 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 are basically Korean winding machines and Japanese winding machines.

In recent years, the 12V27A battery winding machines and capacitor winding machines of Korea's KOEM have occupied a large market share, first of all because of mature and stable technology, moderate prices, and timely after-sales service. In addition, due to the influence of the dispute between Japan and our country, the market share of Korean winding machines is increasing.

● Production mode selection Pole entry method selection: first enter the positive electrode and then the negative electrode; first enter the negative electrode and then the positive electrode; positive and negative electrodes enter at the same time;

● Outsourcing end method: (positive or negative) electrode outsourcing and diaphragm outsourcing can be selected;

● Winding mode: constant angular velocity mode or constant linear velocity mode;

● Features: stable operation, convenient debugging, simple operation.

Features of 12V27A battery winding machine

1. Single-station winding is adopted to effectively ensure the consistency of the battery cell.

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

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

4. The pole piece pre-winding is pressed in by the guide wheel, which effectively ensures the position of the pole ear of the battery cell.

5. In the glue sticking method, the tape is first pasted on the tail of the positive pole piece according to the process requirements, and the battery cell is automatically wrapped after the battery cell is wound. This method of glue sticking first makes the appearance of the battery cell smooth, and will not cause the wrinkling of the outer pole piece caused by the traditional glue sticking method. Secondly, the battery cell can be wrapped with less tape, which saves tape and reduces the thickness of the battery cell.

6. The winding needle adopts an adjustable method. The width of the winding needle is adjusted according to production requirements, and the specification is changed conveniently and quickly.

7. The positive and negative pole pieces adopt a double-correction precision mechanism to ensure the alignment of the pole pieces and reduce the short circuit caused by human operation during the winding process.

Foreign companies that produce 12V27A battery winding equipment have a long history of technological development and a high brand effect, but their production processes are relatively rigid, and most of them only supply standardized testing systems, which cannot meet the customized needs of domestic customers. Moreover, most foreign companies rely solely on agents for sales, and their domestic service capabilities are relatively weak. Domestic manufacturers are more flexible, cost-effective, and more competitive, and the domestic production rate of activation and capacity detection equipment has exceeded 90%. If domestic 12V27A battery winding equipment brands want to have more market share, they will face more competition from their own domestic brands.
