Single Sided Automatic Battery Spot Welding Machine

Product Overview

This automated single-sided spot welding system is built for efficient assembly of cylindrical battery packs. A rotating, servo-driven welding head combines programmable motion with controlled positioning to weld pure nickel up to 0.3 mm thick. The equipment is designed to support repeatable weld placement, uniform weld appearance, and dependable output for production environments where pack quality and cycle time directly affect throughput.

The unit supports series and parallel combinations of 14500, 18500, 18650, 18730, 21700, 26650, and 32700 cylindrical cells. It is suited to battery packs for power tools, self-balancing scooters, energy storage, scooters, and electric vehicles. Multiple-program operation, rapid model changeover, and flexible welding-data entry help manufacturers handle varied cell layouts without sacrificing production continuity.

Built around a high-speed PLC, four servo axes, water cooling, fault alarms, and real-time welding monitoring, this system addresses demanding battery-pack production requirements. Its transistor spot welding power source provides fast welding response with low weld-point temperature, while automatic alarms and stop functions help operators identify undercurrent or abnormal welding events before they affect ongoing production.

Key Features

• Rotating Servo Welding Head: The servo-powered head provides rotation within a configurable plus or minus 45-degree range. This capability supports welding paths and nickel-strip geometries that require angled head positioning.

• High-Output Battery Pack Throughput: The equipment delivers an approximate production efficiency of 1,500-2,000 cells per hour. This output level supports high-volume cylindrical-cell pack assembly while maintaining a controlled automated workflow.

• Pure Nickel Welding Capability: The system is designed to weld pure nickel strip from 0.1 mm to 0.3 mm thick. For 0.21-0.3 mm nickel, slotted or embossed material preparation is required, enabling the welding process to be matched to heavier interconnect material.

• Fast Transistor Spot Welding Power: The supplied 10,000 A transistor spot welding power source operates at a 2-10 ms welding speed. Fast response and low weld-point temperature support efficient joining with controlled thermal input at the weld location.

• Real-Time Welding Condition Monitoring: The equipment monitors welding in real time for undercurrent and explosive sparking conditions. When current is too low or an abnormal condition occurs during welding, the machine alarms and stops automatically.

• Independent Positive and Negative Welding Settings: Configurable welding specifications allow positive and negative terminals to use different current settings. This gives operators a practical method for applying process settings according to the requirements of each terminal location.

• Three Welding Data Input Methods: Operators can create programs using dot-matrix input, array input, or USB import. CAD welding data can be imported to the touch screen one set at a time, exported in batches to USB, and transferred for use on other machines.

• Fast Product Changeover: Up to 199 groups of data can be called up for different products. Combined with straightforward setup and mold-name entry in Chinese or English, the system is designed to simplify changes between supported pack configurations.

• Water-Cooled Welding Assembly: A water chiller is supplied, and the welding head includes a water-cooling system. This arrangement supports stable operation of the welding assembly during repeated production cycles.

• Formed Nickel Strip Compatibility: The equipment uses formed nickel strip to reduce material waste. Compatibility with formed or embossed nickel strip is confirmed during customization, helping the production setup align with the selected interconnect design.
