Key Features & Advantages
  • Premium Copper Sealing Cores: Outfitted with high-grade copper thermal blocks providing exceptional heat transfer, minimized power loss, and high operational efficiency.
  • Adjustable Interface Downforce: Mechanical sealing pressure of the upper and lower dies can be adjusted easily via an integrated regulating valve to suit customizable material metrics.
  • Linear Bushing Head Tracking: Cylinder-driven welding head translates smoothly along high-stiffness linear guide bushes, guaranteeing clean mechanical alignment and tight parallel margins.
  • Autonomous Puncture Sequencing: Features an automated built-in gas pocket puncture function to extract internal outgassing fractions cleanly before sealing.
  • Precision Guided Vacuum Cavity: Pneumatic-driven vacuum chamber works along a precise linear guiding structure, ensuring highly reliable sealing performance and absolute gas tightness.
  • Universal Pouch Size Adaptability: Easily accommodates broad pouch battery specs and lengths up to 300mm via simple internal mechanical layout tuning.
  • Ergonomic Lightweight Layout: Merges a compact structural cabinet footprint with light total assembly mass, delivering user-friendly tool operation and attractive appearance.

APPLICATION SCOPE: Pouch cell secondary vacuum sealing, post-injection degas hot-pressing, air bag automated puncture, and final edge boundary leveling.
FACILITY REQUIREMENT: Benchtop pilot workspace or integrated laboratory line placement. Total Net Weight: 50 KG. Power consumption requires a standard single-phase AC 220V grid interface drawing 900W.
IMPORTANT NOTICE: This device applies hot compression forces up to 7 Kg/cm² under extreme vacuum limits down to -95 KPa. Ensure that pneumatic inputs maintain a continuous 0.5–0.7 MPa supply line feed and clean volatile electrolyte residues off the copper faces routinely to preserve the ±1.5°C precision thermal tracking.

This machine requires a compressed air supply of 0.5-0.7 MPa and a stable AC220V/50Hz power source. The sealing head operates at temperatures up to 250°C, necessitating thermal protective measures for operators.

  • Air Supply: Ensure compressed air supply is maintained between 0.5 and 0.7 MPa for reliable cylinder actuation.
  • Power Supply: Connect to a grounded AC220V/50Hz power source rated for at least 900W to prevent electrical overload.
  • Sealing Temperature: Monitor sealing head temperature to remain within the adjustable range of ambient to 250°C to avoid thermal damage to the battery pouch.

This procedure describes the safe initialization and operation of the secondary vacuum sealing machine for pouch lithium batteries. It covers parameter setup, battery loading, and the sealing cycle including automatic puncture and vacuum steps.

Required Equipment: Secondary Vacuum Sealing Machine (Atomfair-VSE816)

  1. Connect utilities
    Connect the compressed air supply (0.5-0.7 MPa) and AC220V/50Hz power source to the machine.
  2. Set process parameters
    Adjust the sealing head temperature, pressure, time, and vacuum degree on the control panel to the required process values.
  3. Load battery
    Load the pouch battery into the sealing chamber, ensuring proper alignment with the sealing head.
  4. Initiate sealing cycle
    Activate the automatic puncture function to break the gas bag, then initiate the vacuum cycle to achieve the set vacuum degree.
  5. Perform hot-press sealing
    Press the heated sealing head against the battery pouch for the set duration and pressure after vacuum is reached.
  6. Retrieve sealed battery
    Wait for the chamber to vent to atmospheric pressure, then remove the sealed battery from the chamber.

How does the ±1.5°C temperature control accuracy impact seal consistency for pouch battery sealing processes?

The ±1.5°C accuracy ensures precise thermal management critical for consistent seal integrity across batches. With a sealing head temperature range from room temperature to 250°C, this control minimizes thermal degradation of the polymer sealant layer while maintaining sufficient flow for hermetic closure. The copper sealing head further enhances heat transfer efficiency, reducing energy consumption and thermal lag.

What pouch cell dimensions and battery sizes are compatible with the Atomfair VSE816 secondary vacuum sealing machine?

The VSE816 accommodates various pouch battery sizes with easy adjustment, supporting a maximum sealing length of 300mm and a customizable sealing width (default 5mm). The adjustable upper and lower head pressure via pressure regulating valve allows adaptation to different cell thicknesses and pouch materials. The cylinder-driven chamber with precise linear guiding provides reliable sealing performance across a range of battery geometries.

What are the utility requirements for operating the Atomfair VSE816 vacuum sealing machine in a laboratory setting?

The VSE816 requires a compressed air supply at 0.5–0.7MPa and AC220V/50Hz single-phase power with 900W capacity. The vacuum system achieves up to -95KPa, necessitating a robust vacuum line or pump connection. For dry room installation, the machine dimensions (L700×W500×H900mm) and weight (50kg) require adequate bench space and structural support.

This vacuum sealing machine is engineered for secondary sealing of pouch lithium batteries after electrolyte filling, featuring a copper sealing head for efficient heat transfer and adjustable vacuum up to -95KPa with automatic puncture capability. It requires compressed air and 220V/50Hz power, and its 50 kg weight demands robust benchtop support.

Positive

  • Copper sealing head for efficient heat transfer: The copper sealing head provides superior thermal conductivity, improving temperature uniformity across the seal bar and reducing energy consumption during operation.
  • Precise temperature and pressure control: Temperature control accuracy of ±1.5°C combined with adjustable sealing pressure (0–7 Kg/cm²) and time (0–99 s) allows fine-tuning for various pouch cell chemistries and foil laminate thicknesses.

Trade-offs

  • Requires compressed air and specific power: The machine needs an external compressed air supply of 0.5–0.7 MPa and a dedicated AC220V/50Hz power line, which may require laboratory infrastructure upgrades.
  • Significant weight and footprint: Weighing 50 kg with dimensions of 700 × 500 × 900 mm, the unit demands a sturdy benchtop and sufficient lab space for installation and operation.
