Five Axis Double Sided Automatic Servo Spot Welding Machine

Product Overview

This automatic double-sided servo spot welding system is engineered for efficient interconnection of cylindrical lithium battery cells and nickel strips. It combines programmable motion, double-sided welding capability, configurable transistor power, and real-time welding-current monitoring in one production-focused platform. The equipment supports point-by-point programming, array programming, and graphic import, allowing operators to create repeatable weld paths for pack layouts with varied cell counts and geometries.

The unit is suited to battery pack manufacturing, lithium battery module assembly, pilot-line production, and laboratory-scale cell-pack development. It accommodates common cylindrical cell formats including 18650, 21700, 26650, and 32650 cells, with a standard maximum loading capacity of 360 pieces of 18650 lithium cells. It is designed for welding pure nickel and nickel-plated steel strips within the specified thickness ranges.

For demanding production environments, this system incorporates a water-cooled welding head, adjustable imported spring pressure, precision linear guides, and servo-plus-stepper transmission. Weld-current monitoring and false-weld or insufficient-weld alarm functions provide immediate process visibility, helping users identify abnormal welding conditions while maintaining high-throughput operation.

Key Features

• Double-Sided Automatic Welding: The equipment performs automatic double-sided spot welding to improve production efficiency for cylindrical cell interconnection. Its automated workflow is designed for repetitive pack structures where weld placement consistency directly affects assembly quality.

• Configurable Transistor Power Supply: A transistor power supply is available in 5000A, 6000A, and 8000A options. The selectable power configuration enables the system to be matched to the specified nickel-strip material and thickness requirements of the application.

• High-Speed Spot Welding Output: Spot welding can operate at 0.5 s per point, with stated productivity of 3500 to 4000 pieces per hour. For flat welding, the stated welding rate is 0.3 to 1 s and 4000 to 5000 pieces per hour; projection welding is rated at 0.5 to 1 s and 3500 to 4000 pieces per hour.

• Flexible Programming Methods: Operators can program any individual point, create array-based programs, or import graphics for welding-path setup. Up to 99 programming file groups can be stored, supporting rapid retrieval of established battery-pack welding patterns.

• Breakpoint Restart Capability: The system supports restart from a breakpoint, helping preserve workflow continuity when an operation is interrupted. This function is valuable for complex weld programs and production tasks where restarting an entire sequence would be inefficient.

• Real-Time Weld Current Monitoring: An integrated welding-current monitoring system tracks welding current during operation. False-weld and insufficient-weld alarm functions provide an immediate warning of abnormal welding conditions so operators can respond promptly.

• Water-Cooled Welding Head: Circulating water cooling at the welding head dissipates heat during repeated welding cycles. This design reduces welding-needle loss and supports improved welding results during sustained operation.

• Adjustable Welding Pressure: Imported spring pressure at the welding head can be adjusted from 1.0 to 5.0 kg. This adjustment allows the welding interface to be set according to the strip type and welding process being used.

• Precision Motion Architecture: Servo and stepper drive components work with imported precision linear guideways for controlled positioning. The motor transmission system provides a maximum speed of 1000 mm/s, while imported motors are available as an option.

• Broad Cylindrical Cell Compatibility: The equipment is specified for 18650, 21700, 26650, 32650, and other cylindrical lithium batteries. Its 650 mm Y-axis travel and 350 mm Z-axis travel support automated access across multi-cell fixture layouts.
