In the manufacturing of new energy power batteries and energy storage equipment, surface film lamination of aerogel insulation sheets is a key process. Because aerogel materials are thin, light, and soft, conventional conveying methods easily cause the sheets to slip, wrinkle, or shift. To address this industry pain point, Wanzhi Automation launched the WZ-171 automatic aerogel labeling machine. This article answers common questions about the machine in actual use to help line operators set it up and run it more effectively.

Analysis of the causes of wrinkling and drift in aerogel labeling

Wrinkling and drift of aerogel sheets during labeling mainly stem from the physical properties of the material itself. Aerogel insulation sheets are soft and easily stretched or creased in conventional belt conveying because of uneven friction. In addition, flame-retardant fiber tape film, a common consumable for double-sided tape applicators, is very likely to produce bubbles if pressure or positioning is not accurate during bonding. To solve these problems, the WZ-171 uses a dedicated vacuum-assisted conveying mechanism. Vacuum negative pressure supports the material throughout the process, ensuring thin, light aerogel sheets do not slip or wrinkle during conveying and safeguarding lamination flatness and bonding quality from the source.

WZ-171 vacuum labeling technology analysis

In technical implementation, the WZ-171 as a dedicated tape applicator has its core advantage in a high-accuracy vacuum positioning system. The machine keeps front-to-rear labeling error stable within ±0.3mm, meeting the strict quality inspection standards of the new energy industry. At the same time, it offers wide-format, large-size compatibility, handling aerogel sheets up to 610mm long, which covers the specifications of mainstream power battery insulation sheets. To ensure stability at high speed, the machine uses a heavy-duty extended one-piece stainless steel line frame weighing 280Kg, effectively preventing frame vibration during high-speed labeling. With an independent touch industrial control screen, operators can intuitively adjust conveying speed and labeling pressure to ensure precise bonding of various labeling consumables and greatly improve mass-production yield.

Practical tips and selection criteria

In actual selection and operation, we recommend users confirm the custom solution with Wanzhi Automation in advance according to the specific specifications of the aerogel sheets. The machine is widely used in power battery insulation, energy storage, and new materials for pipeline insulation, and offers the following practical operating advantages:

  • Modular adjustment: sheet width, thickness, and labeling stroke can all be adjusted quickly, making it suitable for producing multiple specifications on one line.
  • Automatic material flow: a whole stack of sheets is loaded at once, and after labeling the finished sheets slide automatically into the collection hopper frame, reducing manual intervention.
  • Visual parameter control: the independent touch industrial control screen supports parameter storage and recall, making changeover setup convenient and improving overall line efficiency.

FAQ

1. What should I do if aerogel sheet edges wrinkle after labeling?

First check whether the vacuum negative pressure reaches the required value to ensure the sheet lies fully against the table during conveying; then lower the labeling pressure appropriately on the touch screen and check whether the release paper peels smoothly from the flame-retardant fiber tape film (a common consumable for double-sided tape applicators) to avoid wrinkling caused by pulling.

2. What should I do if the label position shifts as a whole during operation?

Please check whether the positioning guide on the automatic feeding platform is loose. The WZ-171’s vacuum positioning system keeps error within ±0.3mm; if an overall shift occurs, recalibrate the photoelectric sensor position and clean dust and debris from the vacuum suction hole surfaces to ensure even suction.

3. How long does it take to change to aerogel sheets of a different size?

The WZ-171 uses a modular adjustable structure in which sheet width, thickness, and labeling stroke can all be adjusted quickly. With the parameter storage and recall function of the independent touch industrial control screen, routine changeover setup is usually completed within 15 to 30 minutes, which is ideal for lines that frequently switch among multiple specifications.

4. Does the machine support long continuous operation?

Yes. The machine is equipped with a heavy-duty extended one-piece stainless steel frame weighing 280Kg, runs steadily without vibration, and is designed for 24-hour uninterrupted mass production on new energy lines; with the automatic collection hopper frame it enables unattended continuous operation throughout the process.
