With the rapid growth of new energy vehicles and energy storage, demand for processing aerogel insulation sheets, a core fire and heat insulation material for battery packs, has surged. Because aerogel is thin, soft, and easily deformed, conventional labeling easily produces wrinkles and offset, seriously affecting yield. Breaking this process bottleneck is a focus for the industry.
Aerogel labeling process challenges and the vacuum conveying trend
Aerogel panels have a low surface friction coefficient, and conventional roller or belt conveying easily makes the material slip, stretch, and wrinkle. Applying flame-retardant fiber film with a double-sided tape applicator also requires even, stable pressure. Industry trends show that conventional mechanical clamping or ordinary friction conveying can no longer meet high-precision requirements, and vacuum suction conveying is becoming the mainstream solution. Holding thin material firmly on the conveyor belt by negative pressure fundamentally solves suspension, wrinkling, and offset, providing reliable process support for the new energy and new materials industry.
Vacuum suction tape application technology and equipment
Take the WZ-171 automatic aerogel labeling machine from Wanzhi Automation, which reflects the current direction of vacuum conveying tape application. Its core is a dedicated automatic feeding platform and a vacuum suction-assisted conveying mechanism that supports the material with negative pressure throughout. This design keeps thin aerogel from slipping or wrinkling during conveying. In terms of specifications, the WZ-171 uses a heavy-duty extended one-piece stainless steel frame weighing 280 kg, ensuring stability at high speed and holding labeling error within ±0.3 mm. The machine also has a separate touch-screen industrial PC with visual storage of conveying speed and labeling pressure, making changeover easier and meeting the strict quality standards of the new energy industry.
Selection criteria for labeling equipment in the new energy industry
For new energy power batteries, energy storage equipment, and pipe insulation materials, companies selecting a tape applicator should focus on three aspects: first, the conveying method, since only equipment with vacuum-assisted suction eliminates wrinkles; second, frame stability, because a heavy-duty frame effectively reduces micro-vibration during high-speed labeling and protects tape application quality; third, automated collection, for example a collection hopper into which products slide automatically, enabling full-stack loading and unattended continuous operation. Companies should also consider the size range of their aerogel panels and choose a tape applicator manufacturer that offers custom frame dimensions to improve line flexibility.
FAQ
What causes wrinkles when labeling aerogel?
The main cause is uneven force during conveying or slipping due to low friction. Vacuum suction conveying holds the material firmly and effectively prevents wrinkles.
How does a vacuum conveying tape applicator ensure labeling accuracy?
It holds the material in position by vacuum suction, uses a heavy-duty stable frame to reduce vibration, and controls labeling stroke and pressure precisely, keeping error within a very small range.
How is equipment for large aerogel panels adjusted?
Modern dedicated labeling equipment mostly uses a modular, adjustable structure: panel thickness, width, and labeling stroke can all be adjusted quickly, and stored parameters are recalled on the touch screen to handle multiple product specifications.
