Battery production requires extreme precision and efficiency, especially when preparing battery surfaces for processes like welding, coating, or labeling. One critical step in this workflow is the removal of PVC films from the battery surface. For this purpose, laser stripping machines have become the industry standard due to their accuracy, safety, and efficiency.

What is a Battery Laser Stripping Machine?

A battery laser stripping machine is an automated tool designed to remove PVC/PET films from battery surfaces using a high-precision laser beam. These machines are commonly used for cylindrical batteries like 18650 and 21700, which are widely used in electric vehicles (EVs), power tools, and energy storage systems.

Why Remove PVC Films from Batteries?

PVC films serve as protective insulation for batteries. However, during assembly, the film needs to be stripped in certain areas (such as the positive/negative terminals) for the following purposes:

• Spot welding and other joining processes

• Applying insulation paper or electrodes

• Testing conductivity

Manually removing PVC films is inefficient, error-prone, and can cause battery damage. This is where laser stripping machines excel, offering a more reliable solution.

Advantages of Using a Laser Stripping Machine for PVC Film Removal

1. High Precision and Accuracy
   Laser stripping machines offer micron-level precision, ensuring PVC films are stripped without damaging the battery’s surface. This results in clean, smooth removal while preserving battery integrity.

2. Efficiency and Speed
   Laser stripping is significantly faster than manual stripping, ensuring high productivity in automated production lines. It reduces production time and minimizes bottlenecks.

3. No Physical Contact – Damage-Free
   Since the laser process is non-contact, there is no risk of scratching or deforming the battery surface, which is crucial for maintaining battery quality.

4. Consistent Results
   Automation guarantees consistent stripping quality across all batteries, something that’s difficult to achieve with manual processes. Each battery undergoes the same high-precision treatment.

5. Compatibility with Various Batteries
   Laser stripping machines can be customized to handle different cylindrical battery types, such as 18650 and 21700, as well as other battery sizes and shapes.

6. Clean and Eco-Friendly
   Laser technology eliminates the need for mechanical tools or chemicals, making it a clean, energy-efficient solution with minimal waste.
