Wrinkled or misaligned film on new energy aerogel insulation sheets? A vacuum conveying and tape application solution and selection guide

In the manufacture of new energy power batteries and energy storage equipment, aerogel insulation sheets are key fireproof and insulating materials. However, when flame-retardant fiber tape labels are applied to their surface, the thin, light and easily deformed material readily wrinkles or shifts. Ensuring accurate, stable film lamination and labeling is a core pain point in line upgrades. This article explains the vacuum conveying tape application solution for aerogel materials and the key selection points.

Process challenges in aerogel film lamination and labeling

Aerogel panels have extremely low density and excellent thermal insulation, but their physical properties mean they stretch or crease easily under load. Conventional labeling often uses mechanical roller pressing or simple belt conveying, which struggles with such thin, light material and its unusual surface friction coefficient. When a standard double-sided tape applicator is used for lamination, even slight tension changes during conveying lift the edges or crease the center of the aerogel panel, spoiling appearance and potentially compromising insulation performance. For the new energy materials industry, dedicated labeling equipment with gentle support and precise positioning is therefore essential to solve film lamination and labeling at the root.

Vacuum conveying tape application technology and equipment advantages

To solve this industry pain point, Wanzhi Automation developed the WZ-171 aerogel automatic labeling machine specifically for the new energy industry. It introduces an innovative vacuum-assisted conveying system that holds the material under negative pressure throughout feeding and labeling, completely preventing thin aerogel from slipping or creasing during conveying.

On specifications, the WZ-171 is optimized for large, wide panels; vacuum positioning holds front-to-back labeling error within ±0.3mm, fully meeting the strict quality control standards of the new energy industry. The whole unit uses a heavy-duty extended one-piece stainless steel production line frame weighing 280Kg, keeping it free of vibration at high speed. With an independent industrial touch screen, conveying speed and labeling pressure can be stored visually, making changeover convenient. After labeling, finished parts slide automatically into the collection funnel bin for unattended continuous operation.

Line upgrade selection criteria and applications

During selection and application, focus on compatibility and automation level. For power battery insulation, pipeline insulation and similar applications, we recommend the following key points:

  • Size compatibility: Confirm the machine’s working range, for example compatibility with aerogel panels up to 610mm long, covering mainstream specifications.
  • Degree of automation: Choose a model that supports loading a full stack of panels at once and automatic discharge and collection, greatly saving manual handling costs.
  • Parameter adjustment: A modular adjustable structure and an independent touch screen support products in many specifications and one-touch recall of parameters.

When evaluating a double-sided tape application solution, also confirm whether conveying pressure can be customized to order so it matches the actual pace and layout of your line.

FAQ

How can wrinkling during aerogel labeling be solved?

Wrinkling is usually caused by uneven conveying tension or material that is not fully secured. Use equipment with a vacuum-assisted conveying mechanism that holds the material under negative pressure throughout, removing mechanical pulling and keeping the lamination flat.

What aerogel panel sizes can the machine handle?

Take the WZ-171: it is designed for wide, large panels, accommodating aerogel sheets up to 610mm long, which covers mainstream power battery insulation sheet specifications; length, width and thickness ranges can also be customized.

Is changeover complicated when switching aerogel product specifications?

No. The machine uses a modular adjustable structure and an independent industrial touch screen, so conveying speed, labeling pressure and label length can all be recalled and edited visually; changeover is quick and easy.
