Industry 4.0 Version Single-sided Automatic Spot Welding Machine

Model: AOT-DH-10000RF (5000B transistor power box)



This machine is automatic spot welder for cylindrical batteries such as 18650/21700/26650/32650/32700. The electric control part of the spot welding machine adopts modular design, which has high integration, good versatility and convenient maintenance. The main actuator is controlled by a servo motor, which has high accuracy and good reliability. The electrical circuit of the equipment adopts domestic and foreign standard control devices and devices, which is convenient for maintenance and replacement. It supports automatic rotation of the spot welding head, Autocad data import, array and manual methods, which significantly improves the spot welding efficiency and guarantees the Pack production line.


Function description

1. The programming interface is easy to operate, and supports three methods: CAD map, array and manual. Any group of programming files can be stored.

2. Welding needle replacement forecast and reminder, the welding head adopts water-cooled circulation to dissipate heat, which effectively reduces the loss of welding needles and improves the welding effect.

3. Built-in welding current monitoring system, can monitor welding current, with false welding and false welding alarm function, can monitor welding in real time.

4. With integrated industrial control, all welding parameters can be traced and tracked, which is convenient for data management and simple operation. It has functions such as solder joint tracking, fire explosion, false soldering, and missing solder monitoring records.

5. The 4-axis pure electric model can effectively prevent false welding and frying welding due to unstable air pressure.

6. The Miyachi Rotary Welding Head is adopted. The welding head supports plus or minus 90° rotation. It is suitable for spot welding of nickel sheet shunt grooves at any angle, and the welding head is lightweight, which effectively prevents the welding head from being too heavy and causing the welding battery to deform.
