200mm Rotary Pouch Cell Top Side Heat Sealing Machine

Product Overview

This system is a rotary, four-station heat-sealing solution for finishing the top and side edges of square pouch lithium battery cells. It combines two heat-sealing head groups with a 200 x 200 mm battery tray, enabling top and side sealing to be completed simultaneously. Independently adjustable temperature, time, pressure, and cylinder stroke settings give process teams practical control over the sealing cycle for soft-seal and hard-seal battery packaging operations.

The equipment is intended for lithium battery cell fabrication workflows where pouch-cell top-edge and side-edge sealing must be performed repeatedly and consistently. It supports square pouch cells up to 15 mm thick and is suited to battery R&D lines, pilot production environments, and manufacturing processes that need controlled handling between cell loading, sealing, and unloading.

Built around PLC control, touchscreen operation, pneumatic actuation, and a rotary indexing layout, this unit is designed for structured, repeatable operation. A front safety light curtain causes the machine to reset immediately when a body enters the working area, while the no-cell interlock prevents the corresponding upper and lower sealing bars from performing a sealing action when a tray is empty.

Key Features

• Four-Station Rotary Workflow: The rotary table structure supports a practical load-seal-unload sequence. While the next battery is transferred into the sealing position, the operator can remove the previously sealed battery, helping maintain a continuous working rhythm.

• Simultaneous Top and Side Sealing: Two heat-sealing head groups allow the top edge and side edge of a square pouch cell to be sealed at the same time. This arrangement addresses two critical packaging operations within one controlled cycle.

• Independent Top and Side Temperature Control: Top and side sealing temperatures are separately adjustable from ambient temperature to 250 degrees C. Separate adjustment helps process teams set conditions appropriate to the respective sealing operations rather than applying one common temperature setting.

• Adjustable Sealing Time: Top and side sealing times can each be set from 0 to 99.9 seconds. This enables controlled dwell-time selection during process development, acceptance setup, and routine production operation.

• Configurable Pressure and Cylinder Stroke: Sealing pressure and cylinder travel for the top and side edges are independently adjustable. The adjustment capability gives users direct control over the mechanical part of the heat-sealing process for their battery packaging requirements.

• Soft and Hard Seal Capability: The top seal uses a 3.5 mm wide soft seal with a tab preheating block, while the side seal uses a 6 mm wide hard seal. The equipment can support soft-seal and hard-seal processes through free replacement of sealing bars, with final side-seal width based on the user-provided acceptance product.

• Touchscreen PLC Operation: A touchscreen display and PLC control architecture provide a clear operating interface for the automatic sequence. The operator loads the battery into the tray and presses the two front operating control buttons to initiate automatic transfer and sealing.

• Empty-Tray Sealing Inhibition: When a battery is not loaded into a tray, the corresponding upper and lower heat-sealing bars do not carry out a heat-sealing action. This operating logic helps avoid unnecessary sealing-bar movement during an empty station cycle.

• Front Safety Light Curtain: A safety light curtain is installed at the front of the machine. When body access is detected during operation, the system immediately resets, providing an integrated protection measure around the active sealing area.

Why Choose This Product

• Process control where it matters: Separate adjustment of top and side temperature, sealing time, pressure, and cylinder stroke gives process teams control over both thermal and mechanical sealing conditions. This is especially valuable where top soft-seal and side hard-seal operations have different process requirements.

• Purpose-built pouch-cell handling: The four-station rotary structure, 200 x 200 mm tray format, and simultaneous top-side sealing configuration are aligned with square pouch lithium battery edge-packaging workflows. The unit supports cells up to 15 mm thick without requiring the operator to manually reposition the cell between the two sealing operations.

• Consistent automated sequence: Once the battery is loaded and the two front controls are pressed, the equipment transfers the cell, performs the heat-sealing action, holds pressure for the specified time, and returns the sealing bars. This defined sequence supports repeatable working procedures for laboratory and production teams.

• Flexible sealing-bar configuration: Replaceable sealing bars enable both soft-seal and hard-seal processes. The dedicated 3.5 mm top soft seal with tab preheating block and 6 mm side hard seal provide a clear starting configuration, while the side-seal requirement can be matched to the user's acceptance product.

• Integrated operational safeguards: The empty-tray inhibition logic avoids sealing-bar action where no battery is present, and the front safety light curtain immediately resets the machine when body access enters the work area. These built-in functions support controlled day-to-day operation around an active pneumatic heat-sealing station.
