Automatic Pouch Cell Electrode Die Cutting Machine

I. Equipment Overview

1.1 Equipment Function Overview:

The J520BS-B electrode sheet machine is developed in response to the rapidly growing demand in the power battery market. It is a new type of equipment for precise die cutting and forming of roll materials, which saves labor, increases output, and reduces costs during production.

The launch of this product marks a major leap forward in the processing and die cutting forming of battery electrode sheets.

The overall design of the machine fully draws on advanced technologies and processes from both domestic and international sources, with high manufacturing precision and significant technical advantages.

Applicable for: Forming of lithium-ion battery cathode and anode sheets.

1.5 Equipment Features:

1. Use of this equipment allows for direct die cutting, reducing processes, reducing scrap, saving labor, materials, and time, minimizing material waste, and greatly improving production efficiency, electrode sheet quality, and investment cost.

2. Feeding method: Manual loading.

3. Uses a photoelectric sensing automatic web guiding system to correct material deviation, solving the problem of low product quality caused by material misalignment.

4. Feeding method: Pushed to the die cutting section by a servo motor with a precision ball screw; after punching and forming, materials are automatically fed out.

5. Operation section: Operated via a touch screen with program control; reasonable data can be set according to the product, making operation convenient and fast.

6. Die cutting section: Synchronized with the servo feeding speed; both upper and lower templates are made of cast steel material and undergo multiple stress relief and shaping processes to improve rigidity, parallelism, flatness, and pressure stability precision.

7. Transmission section: Driven by the main motor crankshaft motion, speed can be set according to different products, with stable pressure output to ensure production efficiency.

8. Lubrication method: Automatic oil supply control system to keep the equipment always lubricated and ensure stable die cutting pressure.

9. Forming method: Uses a laser knife die, capable of multi-sheet die cutting per stroke, with high production efficiency, low knife die cost, and quick, convenient changeover.

10. Monitoring method: Uses an advanced fault monitoring and alarm system; in case of a fault, the exact fault location can be accurately displayed on the touch screen, making maintenance convenient. The touch screen enables man-machine dialogue for easy operation.

11. Safety protection: Uses a sensitive light curtain sensor system to ensure operator safety, thereby preventing accidents and avoiding unnecessary losses for the company.
