Pouch Cell PET Protective Film Laminating Machine

Product Overview

This system automatically applies PET protective film to soft-pack lithium battery cells after top and side sealing. It protects the cell surface from scratching during subsequent material flow and handling while providing controlled, repeatable film placement. The equipment is designed for cell widths from 50 to 150 mm, with adjustment capability that supports different battery formats within the specified range.

The unit is suited to pouch-cell manufacturing operations where surface condition, downstream handling quality, and film alignment require close control. A single operator manually loads each cell, making the equipment appropriate for dedicated workstations, pilot production, and production lines that need a practical balance between automation and operator-managed material presentation.

Built around a rigid aluminum-profile frame with treated mechanical components, this system is engineered for sustained industrial use. Its specified production capacity, qualification rate, scrap-rate target, and availability target give procurement and process teams measurable criteria for evaluating line performance under suitable incoming-material, air, power, and connected-equipment conditions.

Key Features

• Pouch Cell PET Surface Protection: The equipment applies protective PET film after pouch-cell top and side sealing, helping prevent surface scratches during later transfer and process flow. This directly supports appearance control for cells that must remain protected before further assembly or inspection.

• Broad Adjustable Cell Format Coverage: Width adjustment covers 50 to 150 mm excluding the air bag, while supported cell height is 80 to 200 mm and thickness is 3 to 12 mm. This range allows the same workstation to accommodate specified pouch-cell formats without changing the core equipment platform.

• Controlled Film Alignment: After film application, specified displacement accuracy is ±1 mm in both the cell length and width directions. The top-edge protective film is applied neatly without skew, with a stated length accuracy of ±0.5 mm for the top edge.

• Low-Bubble, Wrinkle-Free Application Standard: The main-body film application is specified to have few internal bubbles and no wrinkles. This process requirement helps maintain uniform surface coverage and reduces the risk that poorly applied protection creates handling or inspection issues downstream.

• 160 mm Effective Pressure-Roller Length: The film-laminating pressure roller provides an effective length of 160 mm. This defined contact length supports the applicable cell-width range and provides a controlled pressing interface for PET film application.

• Compatible Protective-Film Supply Format: The film-feed arrangement accepts protective-film rolls with a maximum outside diameter of 300 mm and an installation inner diameter of 78 mm. These dimensions give material planners clear requirements for preparing compatible PET film rolls.

• Single-Operator Manual Loading: The workflow requires manual cell placement and enables one person to operate one machine. This arrangement gives the operator direct control of cell loading while the equipment carries out the film application process.

• Format Change Adjustment Logic: When changing cell types, the operator adjusts the gap between laminating rollers and the film-pulling parameters. If the cell-thickness variation is small, roller-gap adjustment is not required, helping simplify appropriate product changeovers.

• Industrial Air and Power Requirements: The unit operates from AC220±10V, 50Hz, single-phase three-wire power, with filtered dry gas at 0.6±0.1MPa during normal operation. Defined utility conditions support stable setup planning before installation and commissioning.

• Protected Operating Access and Durable Finishes: The human-machine interface uses password settings to prevent non-professional personnel from incorrect operation that could introduce equipment or personnel safety risks. Mechanical parts use chrome plating, anodizing, or baked-paint treatment, while the frame and enclosure use specified industrial construction and finishing methods.

Technical Specifications

Why Choose This Product

• Defined Process Performance: The equipment provides explicit requirements for film-placement accuracy, top-edge alignment, bubble control, and wrinkle control. These measurable process points help technical buyers assess suitability for surface-protection operations instead of relying on undefined quality claims.

• Production-Oriented Operating Targets: Specified output of 800-1200pcs/h, a product qualification rate of ≥99.0%, a finished-product scrap rate of ≤0.5%, and availability of ≥95.0 provide concrete operating benchmarks. The stated exclusions and operating conditions make these targets more useful for realistic line planning.

• Robust Industrial Construction: Aluminum-profile framing, a welded square-tube bottom frame, baked finishes, and chrome-plated, anodized, or baked mechanical components support an equipment package designed for an industrial production environment.

• Practical Format Flexibility: Supported cell dimensions and adjustable width accommodate the stated pouch-cell range. Roller-gap and film-pulling adjustments provide a clear procedure for adapting the process when product formats change.

• Controlled and Safer Operation: Password-protected HMI access helps restrict settings changes by non-professional personnel, while defined electrical, pneumatic, installation, and environmental requirements simplify facility preparation and procurement review.
