In the aspect of flexible manufacturing of stator of flat wire motor, BMG-CN has established a complete solution system through more than ten years of unremitting efforts, from micro motor to new energy driven motor, from round wire to flat wire, continuous iterative production process.
In the process of stator torsion of flat wire motor, through theoretical research and process verification, the tooth thickness and lip chamfer are continuously optimized, and the problems of winding height difference and lacquer skin damage are solved successfully.
In the face of the problem of short life of tooling in large-scale production, BMG-CN uses mature Bosch plasma coating technology to enhance the surface hardness and smoothness of tooling, effectively prolong the life of tooling, reduce lacquer skin damage, and then improve production efficiency and product quality, and greatly reduce customers’ operating costs.
In the field of power battery manufacturing, since the delivery of the first 400V power battery packaging wiring in 2012, BMG-CN has launched a new generation of automation program through continuous optimization, which can significantly reduce maintenance requirements and reduce production line footprint by about 30%.
In addition, BMG-CN upgraded the recognition technology based on surface texture features (PUT) developed by Bosch Academia Sinica and applied it to the production of power battery electrodes.
By strengthening the quality control of battery electrode production, this technology solves the problem of production consistency, breaks the irresistible triangle dilemma of “high speed, non-contact and high precision”, and increases the qualified rate of battery performance from 90% to more than 99%.
The defective rate and lithium precipitation phenomenon are reduced, the consistency and safety of the overall battery performance are enhanced, and the service life of the battery is prolonged.
Yao Qi, head of the Asia-Pacific region of battery business, innovated with 20 years of technology accumulation and innovation.
during a visit to the factory, media representatives visited the winding equipment in Changsha, which is used in the manufacture of motor rotors.
The design scheme takes into account the close connection between the performance of equipment and customer products, and realizes the rapid replacement of fixtures of the same type of equipment through standardized interface, which greatly reduces the debugging time.
While ensuring product consistency and high performance standards, it makes the production more flexible and effectively controls the cost.
Cloud visited the winding equipment, in addition, the media representatives also had a close experience of the profound manufacturing heritage of BMG-CN.
At the Bosch coating Center, they learned about Bosch’s 35 years of research and development in the field of plasma coating technology, as well as the practical application of microwave coating equipment independently developed by BMG Germany in the manufacture of automotive parts.
At the same time, the H _ 2-μ Power continuous line coating system specially designed by the Chinese R & D team for PEMFC or electrolytic cell bipolar plate has also aroused the interest of the representatives.
The equipment supports a variety of coating components, including DLC, GLC, Cr, Ti, Au, Ag, Pt, etc.
, and can provide process development, proofing and small batch production services to help customers reduce R & D costs.
Visiting the Bosch coating workshop, in the laser and vision laboratory, media representatives learned about the rich experience of BMG-CN cutting-edge laser development and system design, and witnessed the perfect integration of laser technology and vision technology.
Based on the background of global laser development, BMG-CN continues to explore cutting-edge technologies such as flight welding and explore product requirements such as batteries and bipolar plates to provide customers with customized laser processing equipment solutions.
Through the high integration of vision system and laser processing, laser flight welding can not only reduce the production beat and improve the safety of key processes, but also have the flexibility of non-standard equipment, making the welding process more intelligent and efficient.
