DSP-SAVPM17CSemi automatic winding machine and coiling machine

1 equipment introduction

1.1purpose

This device is applied to the semi-automatic winding machine of round or square lithium-ion batteries. By replacing the winding needle components, it can adapt to the winding of round and square batteries separately, including manual pole piece feeding, automatic needle pulling, automatic winding, and then manual adhesive paper pasting and material unloading.

1.2 characteristic

1. Suitable for oil-based electrodes, water-based electrodes, and various separators;

2. The width of the feeding groove (guide plate) can be adjusted, and one side can be adjusted;

3. The winding shaft is driven by a stepper motor to maintain a constant winding speed;

l4、 The tension of the pole piece and diaphragm during the winding process is relatively constant, and the consistency of the tension of the wound battery cells and the consistency of the position of the pole piece and diaphragm is good; Beneficial for improving the capacity and internal resistance uniformity of battery cells;

5. Continuous diaphragm reduces human contact during the winding process, minimizes internal short circuits and self discharges in the battery cell;

6. Equipment stability and high efficiency;

7. Humanized design, easy to operate;

8. Truly realizing the shared use of roll cylinders and soft packs;

2. Scope of applicable materials

2.1 Requirements for incoming materials

1. Polarized Serpentine Bending Error0.2mm/m;

2. Diaphragm winding error0.3mm;

3. Serpentine bending error of diaphragm0.5mm/m;

4. The length of the tape beyond the edge of the polarizer is less than1.5mm；

5. The exposed length of the extreme ear is less than25mm；
