Balancing efficiency and accuracy in volume labeling of power battery aerogel insulation sheets: how the WZ-171 performs in practice

Balancing efficiency and accuracy in volume labeling of power battery aerogel insulation sheets: how the WZ-171 performs in practice

With the rapid growth of new energy power batteries and energy storage equipment, aerogel insulation sheets are a core fireproof and insulating material, and demand for surface film lamination and labeling keeps rising. However, aerogel is thin, light and soft, so it easily wrinkles or shifts in high-speed automated production. Balancing labeling efficiency and accuracy in volume production is key to upgrading a line.

Industry pain points in film lamination and labeling of thin, light materials and the solution

Conventional labeling of thin, soft aerogel panels faces many challenges. Without rigidity, the material easily slips, stretches or creases in ordinary conveying mechanisms, which directly affects finished-product yield. To address this industry pain point, Wanzhi Automation developed the WZ-171 aerogel automatic labeling machine. As a tape applicator built specifically for the new energy materials industry, it introduces a vacuum-assisted conveying system that overcomes unstable conveying of thin, light materials, providing a reliable hardware basis for automated film lamination on aerogel insulation sheets and helping companies raise line automation.

WZ-171 vacuum conveying and tape application technology

The WZ-171’s core advantage lies in its vacuum suction and integrated structural design. A dedicated automatic feed platform uses negative pressure to support the material throughout, so thin aerogel does not slip or crease during conveying. For accuracy, vacuum positioning holds front-to-back labeling error within ±0.3mm, meeting the strict quality control standards of the new energy industry. The machine handles large, wide panels, accommodating aerogel sheets up to 610mm long, which covers mainstream power battery insulation sheet specifications. The unit uses a heavy-duty extended one-piece stainless steel production line frame weighing 280Kg, keeping it free of vibration at high speed and supporting 24-hour continuous production. When used with double-sided tape application processes or flame-retardant fiber film lamination, its modular adjustable structure allows quick adjustment of panel thickness and labeling stroke, greatly improving changeover convenience and reducing downtime.

Practical line advice and applications

In production, selection and operation should focus on the following:

• Confirm non-standard frame dimensions and conveying pressure parameters with the manufacturer based on the actual length, width and thickness range of your aerogel panels.
• The independent industrial touch screen supports visual parameter storage, so operators can recall conveying speed and labeling pressure for different specifications with one touch.
• The machine is widely used in power battery insulation, energy storage manufacturing and new pipeline insulation materials; after labeling, finished parts slide automatically into the collection funnel bin.

This fully unattended continuous operation saves considerable labor costs. Wanzhi’s sustained technical work in this field provides solid automation solutions for new energy materials manufacturing and moves the industry toward higher efficiency and quality.

FAQ

How does the WZ-171 handle extremely thin aerogel panels?

The machine uses a vacuum-assisted conveying mechanism that supports the material under negative pressure throughout, avoiding the deformation and creasing caused by conventional mechanical clamping or friction and keeping thin panels moving steadily.

How long does it take to switch aerogel panel specifications?

The machine uses a modular adjustable structure with a broad length, width and thickness range. Recalling preset parameters on the independent industrial touch screen and adjusting the mechanical stops makes changeover quick and efficient, greatly reducing downtime.

How is stability ensured at high speed?

The unit has a heavy-duty extended one-piece stainless steel production line frame weighing 280Kg; the physical counterweight absorbs vibration at high speed, keeping labeling free of shaking and improving overall running stability.
