Servo Polymer Battery Top and Side Sealing Machine

Product Overview

This servo polymer battery top and side sealing machine is a single-station system for the sealing stage of polymer and pouch lithium battery production. It combines manual loading and fixture handling with servo-driven upper sealing-bar motion to provide a controlled, repeatable sealing workflow. Adjustable temperature, pressure, and sealing time allow operators to align the sealing cycle with defined battery packaging requirements.

The equipment is suited to top-seal and side-seal operations for polymer cells and soft-pack lithium batteries. It is especially relevant to battery R&D laboratories, pilot lines, sample preparation areas, and controlled low-volume manufacturing where operators need direct handling of individual cells during packaging.

Built around fixture-position detection, pneumatic fixture descent, and servo-actuated sealing, this unit supports disciplined process execution under demanding packaging conditions. A specified sealing-head parallelism of ≤0.02 mm, adjustable operating settings on the touchscreen, and a stated qualified-product rate of ≥99.8% provide practical confidence for controlled pouch-cell sealing work.

Key Features

• Servo-Driven Upper Sealing Bar: After fixture position detection, the upper sealing bar is driven downward by a servo system to complete the sealing action. This controlled motion supports a defined, repeatable sequence at the critical heat-sealing stage.

• Single-Station Top and Side Sealing: The equipment is configured for single-station top-seal and side-seal processing of polymer and pouch lithium batteries. It provides a focused workstation for individual-cell packaging operations rather than a multi-station automated line.

• Wide Adjustable Temperature Range: Sealing temperature is adjustable from room temperature to 300℃ through the touchscreen, with a stated temperature-control accuracy of ±3℃. Operators can set the thermal condition required for the selected pouch-cell packaging process.

• Touchscreen Pressure Adjustment: Sealing pressure is set through the touchscreen. The available pressure range differs by equipment size, enabling buyers to select the configuration that matches the physical scale and pressure requirement of their battery packaging workflow.

• Configurable Sealing Dwell: Sealing time is adjustable from 0 to 99 seconds on the touchscreen. This enables the operator to establish and repeat a defined dwell setting for each sealing cycle.

• Precision Sealing-Head Alignment: The sealing head has a specified parallelism of ≤0.02 mm. This mechanical alignment characteristic is important when maintaining consistent contact conditions across the sealing width.

• Flexible Seal Width Configuration: Standard sealing-head width is 5 mm, with customization available according to customer requirements. This allows the system to be considered for pouch designs that require a different seal-width arrangement.

• Manual Cell Handling with Fixture Control: The operator places the cell in the fixture, manually raises the clamping plate, and moves the fixture into the sealing position. Following sealing, the fixture is returned manually, the cell is released, and the next cell can be loaded, creating a clear and manageable operating cycle.

• Position-Verified Sealing Sequence: The fixture must be detected in position before the cylinder lowers it and the upper bar starts the sealing action. This defined sequence helps ensure that sealing begins only after the fixture reaches the intended workstation position.

• Production-Oriented Reliability Indicators: The system is specified for capacity of ≥1 PPM, a qualified-product rate of ≥99.8%, and an equipment failure rate of ≤2%, subject to the stated exclusions for incoming materials, human factors, process factors, and site utility conditions.

Why Choose This Product

• Defined Mechanical Sealing Sequence: The combination of manual cell positioning, fixture detection, pneumatic fixture descent, and servo-driven upper-bar movement creates a clear operating sequence for controlled pouch-cell sealing.

• Process Settings Where They Matter: Temperature, sealing pressure, and sealing time are all touchscreen adjustable. This gives production and development teams direct access to the core sealing settings specified for the operation.

• Precision-Oriented Sealing Construction: ≤0.02 mm sealing-head parallelism and a 5 mm sealing width provide a technically relevant mechanical foundation for consistent contact across the seal area. Custom seal-width requirements can also be discussed.

• Configuration Choice for Cell Size and Pressure Range: Two equipment configurations address different compatible cell dimensions and pressure ranges, allowing procurement teams to select the system that better fits the intended pouch-cell format.

• Practical Reliability Metrics: Specified capacity, qualified-product rate, and failure-rate targets provide useful performance indicators for evaluating this system as a long-term laboratory or pilot-line packaging investment.
