Equipment Name: Coating Machine

Equipment model: SRBM-0030U

Equipment function introduction: The coating machine is suitable for the "U" -shaped blue film coating on the surface of square aluminum shell battery cell shells and the edge folding process on both sides. Manual feeding or automatic feeding from the previous process, achieving automatic surface cleaning of battery cells by roller brush, scanning code confirmation, automatic U-shaped film wrapping, folding film edges on both sides and the top, hot pressing and shaping of the top film edge, automatic insulation testing, NG discharge sorting, conveying and discharging, and manual material collection. The film roll has inherent adhesiveness. The tension of the film pulling is controlled by the magnetic powder brake of the air expansion shaft, with automatic deviation correction control and automatic fixed-length cutting.

The square aluminum shell battery coating machine is a specialized equipment used for insulating film coating of aluminum shell batteries during the lithium battery production process. It is mainly applied in fields such as power batteries and energy storage batteries. The following is a detailed introduction to the equipment and related key points:

Equipment function

Insulation protection

Precisely wrap the heat shrink film (such as PET, PVC, etc.) around the surface of the square aluminum shell battery to provide insulation, short-circuit protection and anti-corrosion protection.

Appearance encapsulation

Ensure that the film layer is smooth and free of wrinkles, improve the consistency of the battery's appearance, and meet the requirements of product standardization for automated production lines.

Compatibility

It can be adapted to square aluminum shell batteries of different sizes (such as length, width and height specifications), and supports customized adjustments.

Core component

Feeding mechanism

Batteries are automatically conveyed to the film coating station, usually by belt conveyor or mechanical arm grasping.

Positioning and deviation correction system

The battery position is detected visually or by sensors to ensure precise alignment and prevent the film from shifting.

Coating module

Automatically cut the diaphragm, wrap the diaphragm around the battery surface through a mechanical arm or roller, and fix it by hot pressing or adhesive bonding.

Heat shrinkage system

Hot air guns, infrared heating or thermal tunnels are used to heat the film layer, causing it to contract evenly and adhere to the battery surface.

Cooling and shaping

Air cooling or natural cooling is adopted to ensure the stable formation of the film layer.

Detection system

Visual inspection of the film layer integrity, no bubbles/wrinkles, thickness measurement, etc.

Cutting and sorting

Good products and defective products are sorted and proceed to the next process (such as welding and assembly).
