Description: 

The whole line includes many core technologies., such as Bending, Winding, Pin-inserting, Spreading, Twisting, Welding, AIO testing, Trickling, Coating, Electric performance test etc.

The production line integrates many technologies, such as robot system, laser welding, RFID, Machine Vision detection, multi-robot controlling and synergizing etc. Adopt the innovative flexible automatic solution,

the whole production line is intelligent with automatic ordering, automatic feeding, automatic assembly and detection, and automatic packaging etc.

Unique advantages: 

1. Automatic production line

2. Enable to produce the most complex Hair-pin stator production ( 8 layers, 800V oil-cooled, with overline layer + I-pin, Busbar leads 3-phases line from the corolla-ends)

3. CT :122s

4. Modular designing

5. Integrate the Digitalization solution with MES and ERP system, the whole automatic production line can be digitalized managed and controlled by embedded Smart Manufacturing system. Re-define the traditional production mode of the stator, to solve many production problems, such as too many processes, high labor costs, low work efficiency, difficult to guarantee consistent product quality. While to achieve smart production process for flat-wire stator, ensure product quality consistently, reduce labor costs, increase efficiency, reduce TOC.

Application: 

NEV flat-wire stator mass production

Prospect: 

The major OEMers are intent to switch to flat-wire motor. But the penetration rate and installed capacity of hairpin stators are very low currently because of some limitation elements, such as automatic production process, cost, lead-time etc. Along with the flat-wire stator automatic production line to be launched in China market, the market demand of flat-wire stator will increase considerably in couple of years, the market size will getting bigger, which is enable the flat-wire stator manufactures speed up their mass production process, and to accelerate the penetration rate of flat-wire motor.
