Positive and Negative Electrode Current Collector Laser Welding Machine

Product Overview

This system is designed for laser welding positive and negative current collectors on full-tab battery cells. A dedicated cell-positioning fixture establishes the working reference, while a collector-positioning press head holds the collector securely before galvanometer-based laser welding is performed. The result is a controlled manual-load welding station that supports repeatable collector attachment within a defined production sequence.

The equipment is intended for battery-cell manufacturing operations where prepared cells require positive and negative collector welding before manual casing. It is relevant to battery R&D, pilot production, process development, and manufacturing environments that need a defined workflow from cell loading through collector placement, welding, dust extraction, and downstream housing insertion.

Built around pneumatic positioning, fixture guidance, a laser welding assembly, and PLC-based electrical control, this unit addresses the practical requirements of a production workstation. Its stated equipment-related product pass rate is 99%, with equipment availability of at least 95% for failures caused by the equipment, helping teams evaluate process consistency alongside output capability.

Key Features

• Fixture-Guided Cell Positioning: A dedicated cell positioning mechanism combines cylinder actuation with fixture location to establish a stable reference for the prepared cell. This supports consistent presentation of the workpiece before collector placement and welding.

• Controlled Collector Clamping: The welding press-head mechanism uses a cylinder, guide rail, and spring arrangement to press and hold the collector during the welding step. Secure mechanical retention is fundamental to maintaining the intended collector position while the laser process is executed.

• Galvanometer Laser Welding Assembly: The collector welding mechanism integrates a galvanometer, positioning cylinder, and laser source. This assembly is configured to complete laser welding of both positive and negative current collectors in the defined sequence.

• Defined Operator Workflow: The process begins with manual loading of a flattened cell, followed by manual collector placement, pneumatic collector pressing, galvanometer welding, dust extraction, and manual insertion into the casing. This clear sequence helps production teams organize handling responsibilities around the welding operation.

• PLC and Touchscreen Control: The electrical control system includes a PLC, touchscreen, detection sensors, relays, pushbuttons, and associated control components. This hardware foundation supports coordinated machine actions and operator interaction at the station.

• Production-Focused Output Target: The single-machine capacity is specified at no less than 2 PPM, subject to material and process differences. This provides a defined throughput reference for line balancing, staffing considerations, and process planning.

• Corrosion-Conscious Mechanical Construction: The body uses structural-steel square tube construction and the platform uses structural-steel plate with nickel or chromium plating. Aluminum alloy framing with transparent PVC panels forms the enclosure, while aluminum, stainless steel, or corrosion-resistant electroplated materials are prioritized for machine structure.

• Ergonomic Equipment Design: The machine is designed to provide good ergonomic performance. For manually loaded and manually unloaded operations, this focus supports practical interaction with the cell, collector, control interface, and finished workpiece sequence.

Why Choose This Product

• Purpose-Built Welding Sequence: The equipment is configured around the actual collector-welding workflow: locate the cell, position the collector, apply controlled pneumatic holding, weld through the galvanometer assembly, extract dust, and transfer the completed cell for casing.

• Engineering Around Process Consistency: Fixture positioning, press-head guidance, spring-supported clamping, pneumatic actuation, and sensor-capable PLC control form a coordinated foundation for repeatable operation at the workstation level.

• Defined Production Performance: A 99% equipment-related product pass rate, at least 95% equipment availability for equipment-caused failures, and a single-machine output of at least 2 PPM give procurement and manufacturing teams concrete reference points for technical assessment.

• Industrial Material Selection: Structural-steel construction, nickel or chromium platform plating, aluminum alloy enclosure framing, transparent PVC panels, and preference for corrosion-resistant materials support a robust machine build suited to routine operating environments.

• Practical Operator Integration: Manual loading, collector placement, and casing insertion are paired with a touchscreen-equipped electrical control system and ergonomic design objective, enabling the unit to fit a clearly defined production role.
